World’s First CRISPR Edited ReptileAn Albino Lizard The world’s first CRISPR edited reptile the tiny albino lizards have been created by A team of scientists from the University of Georgia, U.S in a DNA breakthrough. THIS METHOD HAS PREVIOUSLY BEEN USED TO CHANGE THE DNA OF MAMMALS, FISH, BIRDS, AND AMPHIBIANS – BUT THIS IS THE FIRST TIME IT HAS BEEN USED WITH REPTILES. By Rahul Mishra

It was previously thought to be impossible to use the technique on reptiles because, unlike other animals, they fertilize their eggs at unpredictable times. In a paper published in the Journal Cell Reports, Douglas B. Menke and his colleagues described how they made an albino version of the brown anole (Anolis sagrei), a species of lizard native to Cuba and the Bahamas. The creature, which is the size of a human index finger, was made using a controversial gene-editing technique called CRISPR-Cas9.

It was previously thought to be impossible to use the technique on reptiles. This was because, unlike other animals, they fertilize their eggs at unpredictable times. At the same time, embryos are hard to transfer from a female lizard, making it more difficult to manipulate them in a lab as has been done with other animals. In this latest research, Scientists from the University of Georgia injected CRISPR reagents into unfertilized eggs in lizard ovaries for the first time. When the eggs hatched, about 50% of the mutant lizards had inherited edited genes on DNA from both their mothers and fathers. This study proves that CRISPR components stay active for several days or even weeks within an unfertilized egg. Doug Menke, an associate professor at the University of Georgia and the lead author of the paper said that his team has been brainstorming on how to modify reptile genomes and manipulate genes in reptiles. Since scientists were injecting unfer-

The scientists now hope to use this gene-editing technique on other animals in a hope to discover more methods of gene editing using CRISPR Cas9 technique.

Scientists Convert Smartphone Into Fluorescence Microscope! Researchers from the U.S. and China have developed a method to transform a smartphone into a fluorescence microscope. IT IS CALLED AS THE HANDHELD SMARTPHONE-FLUORESCENCE MICROSCOPE (HSFM). THIS DEVICE ALLOWS COMPLEX BIOMEDICAL ANALYSES BOTH RAPIDLY AND IS COST-EFFECTIVE. By Rahul Mishra

The Conventional fluorescence microscopes play an essential role to detect different cells and proteins, but they are bulky and inconvenient for point-of-care diagnoses. Bo Dai and a team of interdisciplinary research scientists made the use of liquid polymers to create mini two-droplet lenses dyed with colored solvents. The lenses are compatible across different smartphone devices. The low-cost, equipment allowed them to observe and count cells, monitor the expression of fluorescently tagged genes, and distinguish between healthy tissues and tumors. What is Fluorescence Microscopy? Fluorescence microscopy is a crucial technique in multiple disciplines of Life Sciences. These include cell and molecular biology, environmental monitoring, the healthcare industry. In biomedicine and clinical applications, fluorescent imaging techniques can detect and track cells, proteins, and other molecules of interest with very high sensitivity and precision. Portable microscopes are an essential development on an ideal smartphone platform for mobility and accessibility to a range of users. The fundamental problem faced by the researches is due to the various models of smartphones currently available in the market for users. Scientists aim to develop an attachment for smartphone-based microscopy whose design is independent of a specific phone model. To address this challenge, Dai and team, the team of researchers, developed a low-cost handheld smartphone fluorescence microscope- (HFSM) in a portable size. The HRSM uses a single compact and multifunctional color lens to convert any smartphone model

into a fluorescence microscope. This is done without modifying the attachment design between phones. This experiment was designed to reduced the HRFM device complexity and allowed its adoption across a variety of smartphones. The research team used the tool to demonstrate bright field and fluorescent imaging in various bioanalytical applications within cells, including the tissues.

They transfected the GFP tagged human NLRP3 gene into a 293T human embryonic kidney cell line. After this, the researchers excited the transfected cells with a 480 nm blue light for bright green fluorescence emission. The excitation light filtered through the green lens for fluorescence emission, which Dai et al. captured as green spots using the smartphone. The results correlated well for both lens models (model I and II) relative to values measured using a conventional Fluorescence Microscope.

The research team was inspired by preceding research work on a smartphone lens named the DOTlens developed elsewhere. The work presented here can serve as next-generation multifunctional lens modules for field-portable smartphone microscopes.

For the HFSM module, Dai and team included a color compound lens for imaging as well as light filtering. They developed a mini lens using two high refractive-index (RI) droplets. One of them inside another dyed with colored solvents to transmit the desired emission light to the imaging sensor. During the cell counting experiments, Dai and co-workers clearly distinguished the individual cells and calculated the cell concentration. This agreed accurately with the results obtained from a commercial cell counter to validate the HSFM device. Scientists incubated human liver tissues with fluorescently tagged antibodies to detect regular or defective features of the tissue using the lowcost handheld smartphone fluorescence microscope- (HFSM) equipped with a green lens. Using the smartphone microscope, researchers accurately identified images of healthy tissues, para-tumor tissues, and cancerous tissues.

This scientific gold includes insight from machine learning into the genomic organization as well as the function during development. The research study on 3D genome for understanding genes appears today in Dyer added. the journal Neuron. Michael Dyer, Ph.D., the chair of the St. Jude Department of Developmental Neurobiology and Howard Hughes Medical Institute investigator, said that understanding the way cells organize their genomes during development will help the researchers to understand their ability to respond to stress, injury, and disease. Dyer and Xiang Chen, Ph.D., assistant member of the St. Jude Department of Computational Biology, are the corresponding authors of the research study published. The research study focused on light-sensing rod cells in the retina of the mouse. More than eight thousand genes are turned on or off during retinal development. And thousands of regulatory regions across the genome also play a crucial role in this. Scientists used a technology called ultra-deep chromosome conformation capture or the Hi-C analysis to map those interactions in mouse rod cells.

3D genome The current study captured long-distance interactions between promoters (DNA regions that promote gene expression) and enhancers (regions that increase gene expression) at different stages of retinal development.

In this study on 3D genome for understanding genes, the scientists determined that when a core regulatory circuit super-enhancer for the Vsx2 gene was deleted, an entire class of neurons (bipolar neurons) was eliminated. No other defects were identified. Deletion of the Vsx2 gene causes many more defects in retinal development so the super-enhancer is highly specific to bipolar neurons. Scientists developed a genetic mouse model of the defect that scientists are using to study neural circuits in the retina.

Plants Species Going Extinct 350 Times Faster Than Ever Before Previously this year a United Nations report predicted that up to one million species, as well as fifty percent of all plant on earth, maybe extinct by the end of the century. FURTHERMORE, CURRENT RESEARCH RECORDED THAT 571 PLANT VARIETIES HAVE ACTUALLY VANISHED OVER THE PREVIOUS 250 YEARS. By Ria Roy

Now, a new research study shows that plants have been shed at a rate that is 350 times above the average rate of plant extinctions observed in the fossil record. Although plant extinctions have been common in Earth’s history, human impacts appear to be the main driving force for many contemporary ones. When the data around the globe is considered, in South Africa alone, nearly 80 plant species gone extinct have been declared over the past three centuries. The key drivers behind this loss of plant life are thought to be agriculture, urbanization, as well as the spread of invasive species.

The major problem faced here is in order to accurately determine whether or not a plant is extinct is difficult. For example, data is unavailable for many plant species in our planet and, because most of the plants are longlived like the bristlecone pine trees which can live for up to 5,000 years, we may not be able to document their extinction in our lifetimes. Nevertheless, our sustained actions may contribute to their demise.

“Pelargonidin” In Strawberries – Key For Developing Insulin Pills According to the recent survey, more than thirty million Americans suffer from diabetes and they have to inject themselves with insulin at least two to four times daily. SCIENTISTS HAVE BEEN LOOKING FOR THE WAYS TO ADMINISTER THE MEDICATIONS ORALLY, AND SCIENTISTS AT CARNEGIE MELLON UNIVERSITY HAVE NOW SHOWN THAT SUCH A FEAT IS POSSIBLE WITH A NOVEL “STRAWBERRY TECHNOLOGY INSULIN PILL”.

Whitehead said that they took around 110 fruits and vegetables and they were screened for an ability to open up those gaps between the cells of the intestine wide enough to allow this insulin to pass through it. Here is where strawberries and “strawberry technology insulin pill”come in. The same chemical that makes strawberries red — pelargonidin — which can dilate the intestinal pores in a non-toxic way that later allows them to shrink back to the normal.

Whitehead’s lab has plans to extend its strawberry pigment technology to proteins other than insulin. This means the strawberry technology can potentially be used with other protein therapies too, many of which are used to treat disease conditions like leukemia, osteoporosis and even autoimmune disease. Undoubtedly, such an advance would revolutionize healthcare by removing the pain of injections and improving the daily lives of millions of patients.

Researchers Create Super-Mice That Can See Infrared! Supermice that can see Infrared- Researchers used a nanoparticle solution to grant ordinary mice the ability to see in near-infrared.


The visible spectrum ranges from 380 nanometers to 740 nanometers, which is outside the infrared spectrum whose wavelengths extend from 800 nanometers to one millimeter. Gang Han, the study’s principal investigator and a researcher at the University of Massachusetts Medical School, said Humans could only see visible light. Having the ability to see Infrared would enable humans to have night vision without the use of bulky equipment. Human Beings can see visible light due to unique structures present in the eyes known as rods and cones. They are photoreceptor cells in the retina that absorb photons of light and send corresponding electric signals to the brain. But not all light is absorbed since some wavelengths are too short or too long. As on now, we use specialized equipment’s such as telescopes or thermal cameras to see objects that give off infrared light. Thermal Cameras are equipped with detectors that translate IR radiation by assigning each temperature a shade of a color. Colder temperatures are often given a shade of blue, purple, or green. The warmer temperatures can be assigned a shade of red, orange, or yellow. Supermice that can see InfraredProcedure Involved to Create the mice Han and colleagues injected a particular type of nanoparticles called upconversion nanoparticles (UCNPs) into the eyes of ordinary mice. The nanoparticle solution contains elements such as erbium and ytterbium. These can convert low-energy infrared photons into higher-energy green light that is visible. To test whether the mice could indeed detect infrared, the researchers devised a series of physiological and behavioral tests. During one such test, the mice were placed in a Y-shaped tank of water. Here one of the branches had an opening through which the rodents could escape. The

escape route was marked with visible light in the shape of a triangle, while the other blocked end was marked with a similarly lit circle. After various rounds of training, the visible light was replaced with near-infrared. Hans said that the mice with the particle injection could see the triangle clearly and swim to it each time, but the mice without the dose could not see or tell the difference between the two shapes. Single-dose of nanoparticles in the eyes of the mice gave them infrared vision (IR) for up to 10 weeks. Although there was a minor side effect. The cloudy cornea was seen though it disappeared in a week’s time. Tests found no damage to the retina’s structure, suggesting that the procedure was safe. However, before the same could be done to humans, there’s still a lot of work to do. For one, there are biocompatibility uncertainties since the UCNPs are inorganic. Han and team would like to replace them with organic dyes instead of rare-earth elements. Besides enabling human beings to see beyond our natural capabilities, the procedure could be useful in medicine to correct human red color vision deficits or to trigger drug release upon contact with infrared light.

Startup – Insilico Medicine Designs a Drug In 21 Days Using AI Hong Kong-based Insilico Medicine published a research study on using AI to design a drug shows that its deep learning system could identify potential treatments for fibrosis. THAT DEEP LEARNING SYSTEM CALLED GENERATIVE TENSORIAL REINFORCEMENT LEARNING, OR GENTRL FOR SHORT, WAS SUCCESSFULLY ABLE TO FIND SIX PROMISING TREATMENTS IN JUST 21 DAYS, WHERE ONE OF THE TREATMENT SHOWED PROMISING RESULTS IN AN EXPERIMENT INVOLVING MICE. By Ria Roy

The research study on this has been published in Nature Biotechnology and the code for the model has been made available on Github. Researchers have got an AI strategy combined with AI imagination said Insilico CEO Alex Zhavoronkov, who compares the operation of generative tensorial reinforcement learning (GENTRL) to the AlphaGo machine learning system that Google’s Deepmind developed to challenge champion Go players. Alex Zhavoronkov established the business in 2014. His original background was in computer technology. He spent numerous years working at ATI until it was obtained by AMD in 2006. At that point, he changed gears and decided to go into the biotechnology research field, with an interest in research into slowing down the aging process. He got his Masters from Johns Hopkins and afterward got a Ph.D. from Moscow State University, where his studies concentrated on making use of machine learning to check out the physics of molecular interactions in organic systems. Zhavoronkov then worked for a number of companies however after that returned to Baltimore to found Insilico. Insilico Medicine published a research study on using AI to design a drug on Monday in Nature Biotechnology. The Insilico’s original philosophy was about using deep learning to train neural networks to go through large libraries of molecules to find out the drug targets. Then shortly after founding the company, however, Zhavoronkov became fascinated with Ian Goodfellow’s work in machine learning and decided to switch course.

He said that his initial thought was on whether it is possible to make machines imagine new molecules with particular properties of interest instead of screening large vendor libraries. Screening molecules is how they do it in the traditional drug discovery world, but Zhavoronkov wanted to check if this type of machine learning could do things even more quickly.

hibitors. Insilico company used GENTRL to design new drug candidates. These molecules were then synthesized and a leading candidate was successfully tested in mice. For the AI system to design drug molecules, it took about 21 days. The total time for design, its synthesis, and validation was about 46 days.

Initial research the Insilico company published based around this idea was in 2016. This helped to bring in investment money to the competitive biotech and AI arenas. According to Pitchbook, it has so far raised $24.3 million in investment dollars at a valuation of about $56 million, from backers including A-Level Capital and Juvenescence. The company also has multiple partners across the biotechnology field, including A2A Pharmaceuticals and TARA Biosystems.

Even though none of the drugs designed by GENTRL would appear to be more effective than the inhibitors developed by the traditional research method, the traditional process to develop drug candidate molecules took over 8 years and also millions of dollars to develop when compared to the handful of weeks and approximate $150,000 cost of Insilico’s method of drug discovery using AI.

The current paper on AI system to design a drug has its origin in a challenge put to the company by its colleagues in the chemistry field. They ask the company to use its system to develop potential drugs that can inhibit discoidin domain receptor 1 (DDR1) activity. discoidin domain receptor 1 is an enzyme that is involved in fibrosis. Even though it’s not yet clear if DDR1 regulates those processes, inhibiting its activity is being investigated as a possible therapy for fibrosis. The challenge for Insilico was based on a recently published research from a team at Genentech where they had taken about 8 years to identify promising DDR1 kinase in-

Zhavoronkov said that their molecules drug candidates molecules took over 8 years are amazing and these molecules are a little bit better than what his AI system could do. he added that all now matters here is those years took for drug discovery versus

the people who do not have a lot of knowledge of chemistry doing this stuff. Of course, when considering the grand scheme of drug development, this only represents the very first step. Even though this represents a milestone in demonstrating the potential of AI to identify and design drug candidates in a very short time, it will still take years of clinical trials and millions spent on an investigation before any drug candidate molecule is approved for use to treat against a particular disease. Zhavoronkov also cautions that his company Insilico still has a lot of work ahead of it, though this research is an important breakthrough in drug discovery because it shows the promise of using AI to design a drug. He said that this paper on using AI to design a drug in a very short time will remove a lot of skepticism in big pharma!

Thread-Like Robotic Worm By MIT Researchers That Burrows Into Human Brain

Robotics engineers from Massachusetts Institute of Technology MIT have developed a threadlike robotic worm which can be magnetically steered to deftly navigate into the extremely narrow and winding arterial pathways of our human brain. THIS ROBOTIC WORM COULD BE USED TO QUICKLY CLEAR BLOCKAGES AND EVEN CLOTS THAT CONTRIBUTE TO STROKES AND ANEURYSMS. ALONG WITH THIS, AT THE SAME TIME THIS TECHNOLOGY MAKING THE CURRENT STATE OF ROBOTIC TECHNOLOGY& ITS EVOLUTION EVEN MORE UNSETTLING. By Ria Roy

Strokes are one of the leading cause of death and disability in the US, but if the relieving blood vessel blockages are possible within the first 90 minutes of treatment, it has been found to show dramatically increase survival rates of the patients. This process is a complicated one. But with the help of skilled surgeons to manually guide a thin wire through the patient’s arteries up into a damaged brain vessel which is then followed by a catheter that can deliver treatments or medications or simply retrieve a clot from its place. This is not the only potential for these wires to damage vessel linings as these wires inch through the body. But during the process, the surgeons are exposed to excess radiation from a fluoroscope that guides them by generating x-ray images in real-time. And there is a lot of room for improvement in this area. Here comes the importance of robotic worm designed to remove clots from

the human brain. Using the expertise in both water-based biocompatible hydrogels, and by the use of magnets to manipulate simple machines, the MIT robotic engineers created a robotic worm for human brain featuring a pliable nickel-titanium alloy core with the memory shape characteristics so that when it is bent, it returned to its original shape. The core was then coated with a rubbery paste that was embedded with magnetic particles. Then it was wrapped in an outer coating of hydrogels allowing this robotic worm designed for the human brain to glide through its arteries and blood vessels without any friction that could potentially cause any damages.

The robotic worm was tested on a small obstacle course, with a twisting path of small rings, which was guided by a strong magnet which could be operated at enough distance to be placed outside a patient. The MIT engineers also mocked up a life-size replica of a brain’s blood vessels and it was found that not only could the robot easily navigate through the obstacle but that it had also the potential to upgrade it with additional tools like a delivery mechanism for clot reducing drugs. They even successfully replaced the worm’s metalcore with an optical cable, so that once the robot reached its destination, the robot could deliver powerful laser pulses to help remove a blockage of the human

brain. The robotic worm designed for would not only make the post-stroke procedure faster and faster, but these robots would also reduce the exposure to radiation that surgeons often have to endure during the clot removal process. And when it was tested using a manually operated magnet to steer it, eventually machines can be built to control the positions of the magnets ( MRI machines already surround patients in intense magnetic fields) with an improved accuracy, which would in turn further improve and accelerate the robot’s journey through a patient’s body.

Gene Therapy Reduces Obesity & Reverses Type 2 Diabetes in Mice To overcome the side effects of current anti-obesity drugs, scientists have devised a specific gene silencing therapy against Fabp4- a fatty acid metabolism gene. OBESITY AFFECTS NEARLY HALF A BILLION PEOPLE WORLDWIDE, INCLUDING CHILDREN. ACCORDING TO WHO REPORTS OBESITY-RELATED DISEASES, INCLUDING HEART DISEASE, STROKE, TYPE 2 DIABETES, AND CANCER, ARE A LEADING CAUSE OF DEATH. By Rahul Mishra

Both genetic and environmental factors cause obesity. The development of effective anti-obesity drugs is required. Presently these drugs exhibit severe off-target effects. In a study published in Genome Research, Jee Young Chung and colleagues developed a gene therapy technique that specifically reduces fat tissue and reverses obesity-related metabolic disease in obese mice. Gene Therapy for Obesity and Diabetes- The Study Methodology Scientists used a CRISPR interference system wherein catalytically dead Cas9 protein, and single-guide RNA was targeted to white adipocytes with a tissue-specific fusion

peptide attached. The complex was internalized with limited toxicity to the cells, and upon internalization, the molecule complex decreased the expression of Fabp4 and reduced lipid storage in adipocytes. Chung and team tested their therapy on obese mice, which showed that this therapy delivered well. Mice were on a diet high in fat leading to obesity and insulin resistance. Fabp4 repression resulted in a 20% reduc-

tion in body weight and improved insulin resistance and inflammation after just six weeks of the gene therapy. Additional improvements were seen, including a reduction in fatty lipid deposition in the liver and reduced circulating triglycerides. The current standard FDA-approved treatment shows 5% of body weight loss after one year of treatment in humans.

This CRISPR based gene therapy shows promising results in mice. Further research is required before it can be used in clinical treatment against human disease. Importantly, this study highlights the advances in precision gene-editing technology, which can be translated to other types of therapies.

Collagen also plays a very crucial role in tissue engineering. The ultimate aim of this technology is to harness the potent, regenerative nature of stem cells to create artificial tissues for implants and other applications. Just like a building under construction, stem cells are held in place by a collagen scaffolding while they proliferate and transform into specialized tissue. The primary source of this protein is from animal sources like rat tails, pigskin, and bovine skin. These sources are expensive and are highly prone to infections and various pathological conditions. The scientists from the Department of Biomedical Engineering, IIT Hyderabad, have come up with an inexpensive, eco-friendly method to derive Collagen from Eel Skin and used it effectively to 3D print stem cells According to Dr.Govindharaj, Marine animals thrive in a very challenging environment making their Collagen more resilient and highly bioactive. This promotes the speedy growth of stem cells. As published in their recent paper in The Journal for Cleaner Production, the method used to derive Collagen from eel skin was by treating it with cetic acid, common salt, and pepsin. This method is safe, reduces waste build up in Oceans. Using the eel skin also prevents spreading of toxins and diseases. The use of abundantly available marine eel skin to extract valuable Collagen, i.e., volarisation is what makes this research ” Blue.”

The method as explained by Dr. Govindharaj, The stems cells can be extracted from the bone marrow of the Patient. These stem cells are then mixed with Collagen and 3D-printed into a matrix in which they grow into the desired tissue. Dr. Mano Govindharaj, Dr. Subha Narayan Rath and Mr. Uday Kiran Roopavath responsible for developing low-cost stem cells 3D printing is now working on extending their technique to derive more “blue” Collagen from other marine waste sources like fish skin. They hope that their research provides a practical approach both to protect marine environments and improve human health

Scientists Create 3D Heart Cell-On-Chip Platform According to the Study, Cancer is to become the leading cause of death in the wealthy nations by overtaking Heart Diseases in the coming decades if the current trend continues. BASED ON TWO STUDIES PUBLISHED IN THE LANCET MEDICAL JOURNAL, SCIENTISTS HAVE OBSERVED A GLOBAL “EPIDEMIOLOGIC TRANSITION” BETWEEN CANCER AND HEART DISEASES. By Preety Suman

According to the observation of the study, Cardiovascular disease remains responsible for 40% of deaths among middle-aged adults. Meanwhile, Cancer is now killing twice as many people suffering from heart diseases in wealthy countries. In the opinion of Gilles Dagenais, a professor at Quebec’s Laval University and co-led the study, Cancer is the second most leading cause for death in 2017, responsible for 26% of all deaths. But as the heart disease rates fall continuously, cancer will become the leading cause of death within a few decades.

tions associated, such as heart failure, angina, heart attack, and strokes. 70% of all cardiovascular conditions were contributed by changeable risks like High blood pressure, high cholesterol, unhealthy diets, and other lifestyle factors.

According to the researchers among the estimated 55 million deaths recorded in 2017, 17.7 million were due to cardiovascular diseases and condi-

In High-income countries, readily available treatment for High cholesterol and blood pressure medicines have led to a dramatic decrease in heart diseases in the past few decades.

The team also suggested that higher rates of cardiovascular deaths in low-income countries might be due to lower quality health care. They also found fewer hospitalization rates and little use of heart disease medications in middle-income countries compared to wealthy nations. This Research was a part of Prospective Urban Epidemiologic (PURE) study, published in The Lancet and was also presented at the ESC Con-

gress in Paris. The Countries involved in the analysis are Argentina, Bangladesh, Brazil, Canada, Chile, China, Colombia, India, Iran, Malaysia, Pakistan, Palestine, Philippines, Poland, Saudi Arabia, South Africa, Sweden, Tanzania, Turkey, United Arab Emirates, and Zimbabwe.

Discovery of AD26 Virus May Lead To Cancer Vaccines Researchers From Cardiff University’s School of Medicine have decoded how AD26 Virus infects the body. This research could lead to new vaccines and treatments for diseases like cancer. THEY HAVE LEARNED HOW A VIRUS, KNOWN AS ADENOVIRUS TYPE 26 (AD26), INFECTS HUMAN CELLS. THIS INFORMATION ABOUT THE INFECTION PROCESS COULD BE USED TO MAKE VACCINES TO STIMULATE IMMUNE SYSTEMS TO FIGHT CANCER. By Rahul Mishra

Adenoviruses are clinically essential agents. They cause respiratory distress, gastroenteritis, and epidemic keratoconjunctivitis. As non-enveloped, double-stranded DNA viruses, they are easily manipulated, making them popular vectors for therapeutic applications, including vaccines. Species D adenovirus type 26 (HAdV-D26) is both a cause of EKC and other diseases and a promising vaccine vector.

Bioprinting Complex Living Tissue In Seconds To Revolutionize Tissue Engineering Scientists from EPFL and the University Medical Center Utrecht in the Netherlands have now developed an extremely fast optical method for sculpting complex tissues in stem-cell-laden hydrogels and then vascularizing the resulting tissue. THIS GROUNDBREAKING TECHNIQUE OF BIOPRINTING COMPLEX LIVING TISSUE IN JUST SECONDS WILL REVOLUTIONIZE THE TISSUE ENGINEERING FIELD. By Rahul Mishra

Tissue engineers create artificial organs and tissues that can be used to develop and test new drugs, to repair damaged tissue & even to replace entire organs in the human body. However, the current fabrication methods limit their ability to produce free form shapes and achieve high cell viability. Scientists at the Laboratory of Applied Photonics Devices (LAPD), in EPFL’s School of Engineering, working with their colleagues from Utrecht University, have come up with optical technique bioprinting for complex living tissue. The resulting tissues can then be vascularized by adding endothelial cells. The research team describes this high-resolution bioprinting method for complex tissue in an article appearing in Advanced Materials. This technique will change the way cellular engineering specialists work, allowing them to create a new breed of personalized, functional bio-printed organs.

Damien Loterie, an LAPD researcher and co-author of the study said that unlike conventional bioprinting which was a slow, layer-by-layer process, this new technique of bioprinting complex living tissue in just seconds is very fast and offers greater design freedom without jeopardizing the cell’s viability. The scientists’ work of bioprinting complex living tissue is a real game-changer. Paul Delrot, another co-author, said that the characteristics of human tissues depend to a large extent on a highly sophisticated extracellular structure, and the ability to replicate this complexity could lead to a number of real clinical applications. Using this technique of labs could mass-produce artificial tissues or organs at an unprecedented speed. This sort of replicability is very essential when it comes to testing of new drugs in vitro, and this could help obviate the need for animal testing which is a clear ethical advantage as well as a new way of reducing costs.

The technique is called volumetric bioprinting for complex living tissue. In order to create tissue, the scientists project a laser down a spinning tube filled with a stem-cell-laden hydrogel. They shape the tissues by focusing the energy from the light at specific locations, which then solidify. After a few seconds, a complex 3 Dimensional shape appears, suspended in the gel.

Novel Software That Maps Tissue Insights Similar to Google Maps! A new software, developed by a team led by Max Delbrück Center for Molecular Medicine scientist Dr. Stephan Preibisch, is helping researchers to understand and organize the enormous data generated due to Tissue Microscopy. MODERN LIGHT MICROSCOPIC TECHNIQUES PROVIDE INCREDIBLY DETAILED INSIGHTS INTO ORGANS, BUT THE ARDUOUS AMOUNT OF DATA THEY PRODUCE ARE USUALLY IMPOSSIBLE TO PROCESS AND UNDERSTAND. By Rahul Mishra

How Do Scientists Study Tissues? Recently, researchers have for a few years now, have been able to study large structures like mouse brains and human organoids by making it transparent. CLARITY is perhaps the most famous of the various sample clearing techniques. With this technique, almost any object of study can be made nearly as transparent as water. This enables researchers to investigate cellular morphology in ways which seemed nearly impossible a few years ago.

Promising Bioconjugate Vaccine Against Hypervirulent Superbug Klebsiella Researchers have now produced and tested a promising bioconjugate vaccine against Klebsiella in mice. This is a vaccine that protects against this worrisome superbug i.e, a hypervirulent form of the bacteria Klebsiella pneumoniae. RESEARCHERS, WASHINGTON UNIVERSITY SCHOOL OF MEDICINE IN ST. LOUIS AND VAXNEWMO, A ST. LOUIS-BASED STARTUP., HAVE DONE THIS BY GENETICALLY MANIPULATING A HARMLESS FORM OF E. COLI. By Ria Roy

Klebsiella pneumonia superbug causes a number of variety of infections including the rare but life-threatening liver infections, respiratory tract infections, bloodstream infections, and other infections. Only little is known about how exactly people become infected with these bacteria, and the bacteria are unusually adept at acquiring resistance to the antibiotics. A prototype vaccine against superbug Klebsiella, details of the study which are published online Aug 27 in Proceedings of the National Academy of Sciences, may offer an effective way to protect people against the lethal infection caused by Klebsiella which is hard to prevent and treat generally. David A. Rosen, MD. Ph.D., an assistant professor of pediatrics and of molecular microbiology at Washington University, said that for a long time, Superbug Klebsiella was primarily an issue in the hospital setting, so even though its drug resistance was a real problem in treating these infections, the impact on the public was limited. Rosen who is also the co-author of the study on novel Vaccine against superbug Klebsiella added that now we’re seeing Klebsiella strains that are virulent enough to cause death and severe disease in healthy people in the community. In the past five years, the resistant bugs and the really virulent superbugs that have begun to merge so we are beginning to see drug-resistant and hypervirulent strains which are the very scary factor to be considered. The hypervirulent strains of Klebsiella superbug caused tens of thousands of infections in various countries like China, South Korea, and Taiwan last year, and the bacteria is spreading around the world. Almost half of the people infected with hypervirulent, superbug drug-resistant Klebsiella die. There are two types in

particular which are known as K1 and K2 that are responsible for 70 percent of these cases. Rosen, the senior author Christian Harding, Ph.D., a co-founder of VaxNewMo; and the first author Mario Feldman, Ph.D., an associate professor of molecular microbiology at Washington University and one of the co-founders of VaxNewMo; and his colleagues decided to create a vaccine against superbug Klebsiella. The Klebsiella bacterium’s outer surface is coated with sugars so the scientists designed a glycoconjugate vaccine which is composed of these sugars linked to a protein that in turn helps to make the vaccine more effective and efficient. A similar method of modified vaccines has proven highly successful at protecting people against various deadly diseases such as bacterial meningitis and also a kind of pneumonia. Harding said that the glycoconjugate vaccines are among the most effective vaccine against superbug Klebsiella. But traditionally they have involved a lot of chemical syntheses, which is slow and expensive. Researchers have replaced chemistry with biology by engineering E. coli to do all the synthesis for them. The research team genetically modified a harmless strain of E. coli, converting the E.coli into tiny biological factories that are capable of churning out the protein and the sugars needed for the vaccine making. Then researchers used another bacterial en-

zyme to link the proteins as well as the sugars together. In order to test the vaccine, the scientists gave groups of 20 mice three doses of the vaccine or a placebo at 2-week intervals. Then the team challenged the mice with about fifty bacteria of either the K1 or the K2 strain. The previous studies had already shown that just fifty hypervirulent superbug Klebsiella bacteria are enough to kill a mouse. In contrast to this, it takes about tens of millions of classical Klebsiella bacteria, the kind that affects hospitalized people, to be similarly very lethal. About 80 percent infected with the K1 type and 30 percent infected with the K2 type died of the mice that received the placebo. In contrast to this, of the vaccinated mice, 80 percent infected with K1 and all of those infected with K2 survived. Feldman said that they are very hap-

py with how effective this Vaccine against superbug Klebsiella was and they now working on scaling up the production and also optimizing the protocol to take the vaccine into clinical trials soon. The goal of the study is to get a vaccine ready for human use before the hypervirulent superbug strains start causing disease in even larger numbers of people. Rosen said that he as a pediatrician wanted to see people get immunity to this bug as early as possible and It is still rare in the US, but given the high likelihood of dying or even having a severely debilitating disease, he thinks one could argue for vaccinating everybody. And soon we will not be left with a choice. The number of cases is increasing, and we are going to get to the point that we will need to vaccinate everybody, he added.

Fu led the teams that discovered both short sleep genes. She is also a member of of the UCSF Weill Institute for Neurosciences. human body to sleep or wake.

Though Natural short sleepers sleep less, they don’t suffer any of the adverse health effects associated with sleep deprivation. A study conducted by Fu’s team discovered that people who had inherited a specific mutation in a gene called DEC2 averaged only 6.25 hours of sleep per night. Study participants lacking this variation in the same gene averaged 8.06 hours. This finding provided the first conclusive evidence that natural short sleep is, is caused due to genetic effects. Scientists found that this mutation is rare. Though it helped explain some natural short sleepers, it couldn’t account for all of them. According to UC San Francisco’s Professor Louis Ptáček, MD co-senior author of the new study, sleep is complicated. He is a John C. Coleman Distinguished Professor in Neurodegenerative Diseases. Professor Louis said that the team of scientists didn’t think there was just one gene or one region of the brain telling the

which helps scientists pinpoint the exact chromosomal location of mutations associated with a particular trait. The researchers found that a single-letter mutation in a gene known as ADRB1 that, like the mutation in DEC2, was related to natural short sleep. This lead to the Second Short Sleep Gene being Identified.

The scientists were eager to understand how the newly discovered mutation might lead to short sleep. The researchers performed a series of experiments in lab-grown cells and in mice that had been genetically engineered to harbor an identical mutation in the mouse version of ADRB1. The cell-based tests revealed that the mutant form of the beta-1 adrenergic receptor, the protein that encoded by the ADRB1 gene plays a role in a variety of essentially biological processes degrades more rapidly than the non-mutant version. This suggests that it might also function differently. Additional experiments showed that

wakefulness-promoting neurons in the pons with the mutated version of ADRB1 were more easily activated. Furthermore, the ratio of wakefulness-promoting to sleep-promoting neurons skewed heavily towards the former in mice with the ADRB1 mutation. These experiments suggest that the mutant form of ADRB1 promotes natural short sleep because it helps build brains that are easier to rouse and that stay awake longer. Fu said, most people are chronically sleep-deprived. This has well-known, long-term health consequences. A sleep-deprived person is likely to suffer from cardiovascular disease, cancer, dementia, and metabolic prob-

lems. Natural short sleepers, on the other hand, seem to benefit from this. Fu says scientists have discovered that short sleepers tend to be more optimistic, more energetic and better multitaskers. They also have a higher pain threshold, don’t suffer from jet lag, and some researchers believe they may even live longer. Though the exact reasons for these benefits remain unknown, Fu and Ptáček think their work is an important step towards understanding the connection between proper sleep and overall health.

Researchers Highlight Key Components of Plants’ Immune Systems Key Immune Systems in Plants- Researchers have shed light on the crucial aspect of the plant immune response. THE DISCOVERY, REVEALING HOW PLANT RESISTANCE PROTEINS TRIGGER LOCALIZED CELL DEATH, COULD LEAD TO NEW STRATEGIES FOR ENGINEERING DISEASE RESISTANCE IN NEXT-GENERATION CROPS. By Rahul Mishra

Plants, like humans and animals, have evolved complex immune systems that destroy invading pathogens. But unlike animals, plants lack adaptive immunity. This means specific plant cell must defend itself against all potential pathogens. Plant Cells have disease resistance genes which code for protein complexes. These proteins are coded when plants are infected by pathogens such as fungi or bacteria. Such genes encode traits used by biotechnologists to generate disease-resistant plants and crops. The research team was led by Marc Nishimura, Colorado State University Assistant Professor, Jeff Dangl of the University of North Carolina at Chapel Hill, and Jeffrey Milbrandt of the Washington University School of Medicine. Nishimura and team identified the mechanism of one little-understood domain of plant resistance proteins called a “toll-interleukin-1 receptor,” or TIR domain. The researchers revealed that during the plant immune response, the TIR domain is an enzyme that degrades a molecule

known as NAD+, which is essential for metabolism in all organisms, including humans. By cleaving NAD+, the plant self-destructs infected cells by the pathogen while leaving others unharmed. Scientists had previously suspected that plant’s TIR domains might act like physical scaffolds. These function by building a structure that attaches to the cell’s plasma membrane, in turn, recruiting other proteins to the area to begin an immune response. This is how these domains work in animal cells which includes human beings Nishimura and colleagues’ work shows that the role of TIR domains in the plant immune response is indeed functionally related to the part of the more unusual animal TIR domain. The researchers found that the

plant TIR domain is itself acts as an enzyme that cleaves the NAD+ molecule, rather than acting as a structural scaffold that recruits other components. On the other hand, the animal TIR domain in SARM1 kills the cells by depleting NAD+ levels. The plant TIR domains cleave NAD+ to generate a signaling molecule. This molecule is not seen in animal cells. This molecule is structurally related to a classical signaling molecule called cyclic ADP-Ribose. The team is now working to understand how this new product they saw influences cell death and disease resistance. Nishimura said that For 25 years, scientists didn’t know what the function of TIR domains plants was. There-

fore, Nishimura added that the results were exciting in terms of advancing the understanding of how TIR domains trigger immunity in plants. Key Immune Systems in PlantsWhy is it Important? Nishimura said that discovering individual biochemical pathways in the plant immune response may be necessary to how plants are manipulated to protect food crops. This is particularly more important as new pathogens emerge, and global food supplies become vulnerable. Ultimately this study will help scientists rationally engineer new receptors to recognize emerging pathogens.

Drug Use in the Ancient World Episode 47 By Rashmi Sanyal

We wish there was a pill for everything. From the days we are feeling low to curing the constant pangs of hunger during work. From stress-related hypertension to disturbed sleep and insomnia at night. That day is not far when there would be a library of such treatments available to relieve us from their untimely attack. But where did all of this start from? What were the first disease and its cure? Isn’t excessive use of medication bad for health? Then how was its use controlled in the ancient world? Welcome back to another illuminating episode on Voice of Biotecnika. I, Rashmi, will divulge various facts related to the use of drugs and medications in the ancient world – Drug Use in the Ancient World. So, sit tight and buckle up for a short journey, taking us back in time. Archeological evidence suggests that the ancient world depended on many natural concoctions that would treat mankind or even could be a reason for their enhanced intelligence that is well portrayed behind their genius theories and philosophies. Not only did these compounds have immense use in healing the society, but they also were compounds that were used for its hallucinating and psychoactive properties. Such compounds can be traced to be found throughout the world, under multiple civilizations and in the most incredible and inconceivable locations. For example, imagine finding them in mummies or in the ruins of burned down cities of the ancient world! To analyze this further, the area or location of the presence of such compounds were traced by archeologists. For example, whether such compounds were occasionally found in the old house ruins or whether there were special manufacture and store areas created for these. Incidentally, a lot many such concoctions and elements were found near-religious areas. This gives us the impression

that psychoactive and hallucinating agents might have been used during the performance of many rituals. For example, older civilizations believed in accessing the spirit world for the purpose of healing oneself. Here, the compounds were not used for its recreational benefits, as we perceive them to be in the modern days. Rather they were used to get spiritual oneness and to derive energy from the non-physical realm. A lot of ancient civilizations were in use of these. What was the effect that it had on society? Why is the use of such chemicals regarded as abuse today? In our present-day society the use of many of these chemicals are regarded as “outside the norm” or even illegal in some nations!

however, can only be anticipated. Since the then civilization regarded this knowledge as a sacred mystery, they did not carve it on the then present stone tablets, due to which there is hardly any concrete evidence pertaining to their usage. In many tribal traditions, the ability to communicate with spirits and other entities was a prized skill and much respect was given to the shaman or priest who could facilitate this kind of interaction.

Similarly, alcohol, wine, herbs, concoctions were found almost in every civilization. In Egypt, when famous tombs were dug open, there was evidence of blue water lilies covering the mummy of famous Kings. These lilies behave as a very strong psychoactive drug when soaked in wine for The trouble in solving this mystery a few weeks. lies in the fact that the exact usage of all such chemicals was considered We can only presume its usage. a secret in many societies.

The Romans and the Greeks used opium, as well as numerous botanical toxins to induce states of mental euphoria, create hallucinations, and alter their own consciousness. If such compounds had such a wide variety of usage listed throughout history and civilization, then how did its use become so restricted today? Drug addiction is characterized by an inability to abstain from the drug; impaired behavioral control; cravings for the drug or other pleasure-seeking activities which stimulate the same reward pathways; diminished recognition of behavioral problems; and a dysfunctional emotional response. In this case compounds like sugar, herbs, spices, coffee would all be termed as drugs as their prolonged use may harm mankind. But since they are readily available and marketed with awareness, their use is not abused. Health professionals and senior ranking police officials agree that much harm could be avoided if we let go of the stigma and secrecy surrounding drug use and instead focussed on helping those who experience the problems associated with addiction in a balanced and non-judgemental way. Accepting the significance of drug use throughout history and in virtually all traditional cultures around the world would go a long way to overcoming the taboo which is preventing the rational exploration of their continued use. The human appreciation

for the healing, sacred, entertaining, bonding, pain-relieving and mood-altering experiences that drugs provide is not going to go away – the tradition of their use is simply too strong and too significant. Drug Use in Ancient World – If we look into the history of medicine, we can find how societies have changed in their approach to diseases and illness from ancient times to the present. The Renaissance period had improved understanding of anatomy, and the microscope was invented. Although there is no record to establish when plants were first used for medicinal purposes (herbalism), the use of plants as healing agents, as well as clays and soils is ancient. Over time, by following the behavior of fauna, a deep medicinal knowledge base developed and was passed across generations. Even earlier, Neanderthals

might also have engaged in medical practices. Among the tribal society, specialized casts – shamans and apothecaries used to function as healers. Shamans were known to enter the spiritual world by entering into a trance while the healing process. The ancient Mesopotamians had no distinction between “rational science” and magic. To treat a patient – recitations and chants, as well as herbs and other such magical medications, were administered. The earliest medical prescriptions appear in Sumerian during the Third Dynasty of Ur. In ancient Egypt, the practice of medicine is so specialized among them that each physician is a healer of one disease and no more. Medical information appears in the Edwin Smith Papyrus, an ancient Egyptian medical text, and may date to a time as early as 3000 BC. The Atharvaveda, a sacred text of Hinduism dating from the

September 10th, 2019 Vol. 03 NO 95

Early Iron Age, deals with medicine and is said to be one of the first Indian texts to do so. The Atharvaveda also contain prescriptions of herbs for various ailments. The use of herbs to treat ailments would later form a large part of Ayurveda. Charaka Samhita, Sushruta Samhita includes the knowledge of preserving health and even techniques to modern-day surgery. Hippocrates is considered to be the father of modern medicine. He and his followers are presumed to be the first to describe many diseases and medical conditions. The Romans invented numerous surgical instruments, including the first instruments unique to women. As we advanced into the latest centuries, advanced research centers opened and are often connected with major hospitals. Medicine was heavily professionalized by the 20th century.

There must be some reason behind the fact that why in ancient times, different clans of people started to intentionally select, prepare, and consume various substances that contain certain chemicals. Should the basis of their understanding just be left out to dilute amongst the many theories that modern-day man believes in? Or should we continue to believe in the ancient potions and magic that is the essence of many civilizations each of us seems to have descended from? If you find this topic – “Drug Use in Ancient World” interesting do share your comments below and stay tuned to the upcoming sessions filled with such absorbing and engrossing subject matters. Wishing you all a great day ahead!
