For First Time Insulin Made With Stem Cell-Derived Therapy Stem cell therapies have become increasingly versatile. Two presentations at this fall’s Cell & Gene Meeting on the Mesa in Carlsbad illustrated how the stem cell therapy field is maturing. SAN DIEGO’S VIACYTE IS NOW DEVELOPING 2 VERSIONS OF EXPERIMENTAL DIABETES TREATMENT, USING INSULIN-PRODUCING CELLS GROWN FROM THE EMBRYONIC STEM CELLS. THE CELLS ARE ENCAPSULATED IN A DEVICE THAT IS IMPLANTED BELOW THE SKIN. By Ria Roy
One of the versions, called PEC-Direct, shows intermittent signs of producing therapeutic levels of insulin, the first time this has been seen, said ViaCyte’s CEO, Paul Laikind. And this was seen indirectly through the presence of a by-product of insulin production. However, the production is not reliable enough to substitute for injected insulin, Laikind said. ViaCyte is now working to improve reliability. PEC Direct is meant for the most severe cases of type 1 (insulin-dependent) diabetes. It allows the blood vessels to grow into the device to contact the cells. In order to prevent an immune reaction, the patients get immunosuppressive drugs. The other ViaCyte product, PEC-Encap, shields the cells from direct contact. Immune-suppressing drugs are not required here. However, it did not work well in early testing, because scar tissues built up around the implant.

Researchers Develop New CRISPR-Cas9 Enzyme With High Precision! Highly precise CRISPR-Cas9 enzyme is developed by a group of researchers from the City University of Hong Kong (CityU) and Karolinska Institutet that can enhance the targeting accuracy in the genome editing process. THE NEW CRISPR-CAS9 PROTEIN IS BELIEVED TO BE VERY USEFUL IN HUMAN GENE THERAPIES, WHICH REQUIRE HIGH PRECISION. By Rahul Mishra
CRISPR (Gathered Consistently Interspaced Brief Palindromic Repeats) -Cas9 is a famous gene-editing modern technology that has a broad range of applications, from curing numerous genetic diseases to establishing drought-tolerant plants.

shipment vector called adeno-associated viral (AAV) vector that is typically utilized for in vivo gene therapy. However, SaCas9 is much smaller than SpCas9, as well as can be quickly packaged in the payload-limited AAV vectors for providing gene-editing elements in vivo. Nevertheless, no SaCas9 variation with high genome-wide targeting accuracy was discovered to date. Highly precise CRISPR-Cas9 enzyme SaCas9-HF to increase the precision in genome editing Dr. Zheng Zongli, Assistant Professor of Department of Biomedical Sciences at CityU and the Ming Wai Lau Centre for Reparative Medicine of Karolinska Institutet in Hong Kong, and Dr. Shi Jiahai, Assistant Teacher of Division of Biomedical Sciences at CityU, efficiently crafted SaCas9-HF, a CRISPR Cas9 variant which reveals high precision in genome-wide targeting in human cells without compromising on-target per-
formance. The research group’s finding was based upon a considerable examination of 24 targeted human genetic locations comparing the initial unmodified (wild-type) SaCas9 and also the new SaCas9-HF. For those targets having comparable sequences in the genome and thus prone to off-target adjustment by the wild-type enzyme, SaCas9-HF decreased the off-target task by about 90%. For those targets with rather much less off-target modifying by the wild-type enzyme, this highly precise CRISPR-Cas9 enzyme SaCas9-HF yielded no observable off-target activity. The research findings were published in the scientific journal Process of the National Academy of Sciences (PNAS) labeled “Logically engineered Staphylococcus aureus Cas9 nucleases with high genome-wide uniqueness.”

US Researchers Use Biomarker Blood Test To Reveal Heart Disease Risk Without occasionally looking under the hood, it is difficult to predict whether expensive car repairs lie ahead.
IN A SIMILAR WAY, PREVENTIVE CARDIOLOGISTS ARE NOW LOOKING FOR WAYS TO DETECT EARLY-STAGE HEART DISEASE IN PEOPLE WHO ARE NOT CURRENTLY UNDER TREATMENT. By Ria Roy

The team thinks this type of test can help in the shared decision-making process for patients who are in need of information about their risk, said preventive cardiologist, Dr. Parag Joshi, Assistant Professor of Internal Medicine. Biomarker blood tests are easily accessible and are less expensive than some other tests for risk assessment, he added. Led by Dr. Joshi & Dr. Ambarish Pandey, Assistant Professor of Internal Medicine, the scientists looked at data from about 12,987 participants (mean age 55 years, 55% female) who experienced 825 cardiovascular events, such as heart attacks & strokes, over a median follow-up time of ten years. This information was compiled from the Atherosclerosis Risk in Communities Study, the Dal-
High blood pressure (with other risk factors) is known to increases the risk of heart attacks, strokes & congestive heart failure. Treatment to lower the blood pressure reduces this risk factor. Other parameters that play a role in cardiovascular disease include high cholesterol levels, gender, age, smoking, poor diet, lack of exercise & diabetes. The process of developing the cardiovascular disease can be difficult to pick up on based only on these risk factors. Now there are tests to detect markers of heart disease in people without any symptoms who are actually at higher risk, said Dr. Joshi.
Additional UT Southwestern cardiology scientists who contributed to the study include Dr. Kershaw Patel, cardiology fellow; Colby Ayers, Internal Medicine Faculty Associate; Dr. Wanpen Vongpatanasin, Professor of Internal Medicine; Dr. Jarett Berry, Professor of Internal Medicine; & Dr. James de Lemos, Professor of Internal Medicine. Dr. Vongpatanasin holds the Norman & Audrey Kaplan Chair in Hypertension and the Fredric L. Coe Professorship in Nephrolithiasis Research in Mineral Metabolism. Dr. Berry is a Dedman Family Scholar in Clinical Care. Dr. de Lemos holds the Sweetheart Ball-Kern Wildenthal, M.D., Ph.D. Distinguished Chair in Cardiology.

Getting Mood Swings? Scientists Say This Brain Receptor Is Responsible! A research team has now discovered a unique receptor in the brain i.e, believed to regulate negative moods.

He added the team knew there were GluN3A subunits in the adult medial habenula & NMDA receptors formed with these sub-units were likely to have very different characteristics. The team didn’t expect to find the receptor that they did, said Dr. Otsu. The NMDA receptors normally require two different neurotransmitter molecules i.e, glutamate and glycine, to bind and activate the receptor. The receptor that Dr. Otsu & his colleagues found only needs one neurotransmitter i.e, glycine, to activate it. The receptors direct brain function and are also the target of approximately 40 % of all current medicines. Therefore, this discovery of the rare type of brain receptor and its role in modulating anxiety and its effects of negative experiences means it has the potential to be a highly specific target for mood-regulating drugs.
The team will be embarking on research within the Kolling Institute to further understand the role of this newly found brain receptor, with the ultimate goal of developing drugs to target it. This discovery could lead to advances in mental health & pain medications, he added.
Dr. Aubrey said Yo has brought such a depth of knowledge to the team. He interrogates every aspect of the data i.e, an approach that has enabled him to consistently produce data of the highest level & impact.

Scientists Use CRISPR For Dose-Dependent Gene Activation A group of scientists affiliated with several institutions in the U.S. has developed a way to use the CRISPR gene-editing technique for dose-dependent activation of gene expressions. THE TEAM OF SCIENTISTS DESCRIBES THEIR TECHNIQUE FOR ALTERING GENE EXPRESSION IN AN ALTERNATIVE WAY AND HOW WELL IT WORKED. By Rahul Mishra
Prior studies have shown that gene expression can be suppressed or activated using the CRISPR/Cas9 gene-editing technology. But until now, the CRISPR technique had not been used to enable dose-dependent activation of gene expression. CRISPR For Dose-Dependent Gene Activation- A New Approach In this new effort by scientists, they have found a way to do just that by making use of chemical epigenetic modifiers- (CEMs) that were skillfully designed to activate desired gene expression with the help of some parts of the endogenous chromatin-activating machinery â€” doing, so researchers eliminated the requirement of exogenous transcriptional activators. The new approach involved using two components; the first was Cas9, which was catalytically inactive along with the binding protein FKBP.

Sven Klimpel Professor for Parasitology & Infection Biology at Goethe University in Frankfurt and the Senckenberg Biodiversity and Climate Research Centre said with their new modeling approaches it is possible now to illustrate the risk areas for Zika virus infections in Latin America regions. Klimpel added that the models additionally allows illustrating Zika risk areas for Europe. For example, their models indicate the 2 autochthonous cases in southern France in Département Var (see illustration). And at the end of October, French authorities announced the first Zika case in Europe; about a week later, a second Zika case was made public. According to the scientists’ calculations, the Zika infection risk in South America is highest along the Brazilian East Coast & in Central America. The infection risk is moderate in the Amazon region and the lowest in the
To determine the infectious risk of a specific area, the scientists Dr. Sarah Cunze & Professor Sven Klimpel modeled the potential spread of the 2 species of mosquito, Aedes aegypti & Aedes albopictus. Since the mosquitoes can only transmit this Zika virus in regions where the virus is present in the first place, the scientists included an Evidence Consensus Map in their risk model. This map could categorize the number of reported Zika
illnesses at the regional level. And the average temperature of the warmest quarter was also incorporated in the model since the temperature has a significant influence on whether the virus can survive and then multiply in the mosquito. Finally, the researchers added socio-economic factors such as population density and gross domestic product to their risk model.

FDA Authorizes NGS Test Marketing For Detecting HIV-1 Drug Resistance The FDA has approved the for marketing the Sentosa SQ HIV Genotyping Assay, which is the first HIV drug-resistant assay used in next-generation sequencing technology. THE CAPABILITY TO LOGICALLY CHOOSE THERAPIES FOR PATIENTS READY TO START OR ALREADY TAKING ANTIVIRAL TREATMENT OFFERS AN ADDITIONAL DEVICE IN OUR ONGOING FIGHT VERSUS HIV,” SAID PETER MARKS, M.D., PH.D., SUPERVISOR OF THE FDA’S FACILITY FOR BIOLOGICS EXAMINATION AND RESEARCH STUDY. By Ria Roy
“Today’s consent offers healthcare providers a brand-new tool in helping to choose treatment choices for their patients. The best combination of antivirals can lower viral tons, or the quantity of virus in the bloodstream, and also aid keep patients with HIV healthy for several years. Nonetheless, according to a recent record from the Centers for Disease Control and also Avoidance and also the World Health Organization, the percent of individuals dealing with HIV around the globe that have resistance to some HIV medications has boosted from 11% to 29% given that 2001. FDA Authorizes HIV-1 drug – What Causes AIDS? When HIV infection is untreated, it can cause acquired immunodeficiency syndrome (AIDS) disease. It is transmitted through direct contact with Human Immunodeficiency Virus-infected bodily fluids such as blood, and the majority of Human Immunodeficiency Virus infections in the U.S. are from Human Immunodeficiency Virus-1. According to the Center for Disease Control, there were more than 1 million Americans with Human Immunodeficiency Virus in the year 2016. The present standard of care for patients with Human Immunodeficiency Virus-1 is ART, also known as antiretroviral therapy, the daily combined usage of drugs to treat Human Immunodeficiency Virus by suppressing it. Traditionally, monitoring a patient’s viral lots has been done to evaluate the effectiveness of therapies. Increasing viral loads indicate that the virus might have mutated and that a
patient’s present regimen is not effective at suppressing the virus. Once the virus has mutated or altered, and drug resistance develops, a person should generally change medications intake as different drugs will help to keep the virus from multiplying. FDA Authorizes HIV-1 drug- Why Did FDA Approve It? Food and Drug Administration Principal Deputy Commissioner Amy Abernethy, M.D., Ph.D., said the public health agency, the FDA is precise, aware of the danger of drug-resistant infections and are focused on facilitating the development of safe and effective new treatments to give patients more options to fight life-threatening infections. This diagnostic provides a new way to select effective treatment options, he added. The Sentosa SQ Human Immunodeficiency Virus-1 Genotyping Assay detects Human Immunodeficiency Virus-1 drug resistance mutations in patients taking to start antiviral treatment. This assay will detect mutations in genes of the Human Immunodeficiency Virus-1 virus from a sample of a patient’s blood using New Generation Sequencing or NGS technology. Understanding the mutations in the virus will help healthcare providers to select a very useful combination of drugs in an ART regimen and indication in which drugs may no longer be effective against the mutated HIV-1 virus. The US FDA reviewed data from
performance studies, which demonstrated a greater than 95 percent sensitivity and specificity in detecting 342 HIV drug-resistant mutations and determined the Sentosa SQ HIV-1 Genotyping Assay provides a reasonable assurance of safety and effectiveness for its intended use. FDA Authorizes HIV-1 drug- The Research Data The Sentosa SQ HIV Genotyping Assay is for use only in patients with HIV-1 who are about to start or already taking antiviral therapy and is not intended for diagnosing infection with HIV. Results of this test are intended to be used in conjunction with clinical observations, patient history, and other laboratory evidence to make patient management decisions. The Food Drug and Administration or FDA have reviewed data for the Sentosa SQ HIV Genotyping Assay through the de novo premarket review pathway, a regulatory pathway for devices of a new type.
Along with this authorization, the Food Drug and Administration is establishing criteria, called special controls, which is the requirement that test developers must meet for demonstrating accuracy, reliability, and effectiveness of tests intended to identify the virus mutations. These unique controls, when met along with general controls, provide a reasonable assurance of efficacy and safety for tests of this type. This action will also create a new regulatory classification, which means that subsequent devices of the same type with the same intended use may go through the Food and Drug Administration’s 510(k) pathway, whereby devices can obtain clearance by demonstrating substantial equivalence to a predicate device. The Food Drug and Administration agreed on marketing authorization of the Sentosa SQ HIV Genotyping Assay to Vela Diagnostics USA Inc.

NASA’s Curiosity Rover Detects Strange Oxygen Behavior On Mars The Curiosity Rover by NASA landed in Gale Crater in 2012. Since then, it has been the Martian surface beneath its wheels to learn more about the planet’s history. ALONG WITH THE SURFACE EXAMINATION, CURIOSITY ALSO COLLECTED DATA ABOUT THE PLANET’S ATMOSPHERE. By Rahul Mishra
Curiosity’s tunable laser spectrometer, called SAM, which stands for Sample Analysis at Mars, detected the most significant amount of methane ever measured during its mission. SAM has also discovered that over time, oxygen behaves in a way that can’t be explained by any chemical process researchers currently understand. Sam has revealed the following data about the Mars atmosphere- 95 percent of the atmosphere is carbon dioxide, followed by 2.6 percent molecular nitrogen, 1.9 percent argon, 0.16 percent oxygen, and 0.06 percent carbon monoxide.
Earth, microbial life is a crucial source of methane. NASA also warned that expectations of life should be managed since interactions between rocks & water can also create methane, and Mars has water as well as the abundance of rocks.

It is not in use in the field just yet, then, but that is considerably better than other Artificial Intelligence cancer screening methods that typically don’t exist as more than experiments. There is an incentive to put this into use quickly. TechCrunch noted that roughly about 67,000 women die of cervical cancer in India each year or more than a quarter of the deaths worldwide. At the same time, there is just a handful of doctors that can process pap smears and help women take action. SRL diagnostics alone receives over 100,000 samples per year, and 98 % of those are normal. Microsoft’s Artificial Intelligence would let doctors focus on just the two percent of samples that are problematic and help women start treatment sooner. SRL Diagnostics– Microsoft consortium said they are very hopeful about their APIs and it could find application in other fields of pathology such as in the diagnosis of kidney pathologies and in oral, pancreatic & liver cancers. The consortium aims to expand its reach with more collaborations with private players & governments to expand the reach of the model even in the remote geographical areas where the availability of histopathologists is really a challenge.

Google’s AI Based Search Tool For Analyzing Millions Of Health Records Google, the ever-growing technology company, has been revolutionizing the world since 1998. FROM THE MOST USED SEARCH ENGINE TO THE RECENT DRIVERLESS CARS, GOOGLE CONQUERED ALMOST ALL THE TECHNOLOGICAL INDUSTRIES. By Namitha Thampi
The most prominent players in the world, like Google, Facebook, Amazon, and Apple had been trying to invade the $3 trillion healthcare industry. Among them, Google’s dream is going to come true soon. On November 12, Google declared a partnership with ascension, one of the leading non-profit health systems in the United States. Tariq Shaukat, President, Industry Products, and Solutions of Google Cloud announced that Google would support Ascension with technology to deliver better healthcare across the US. Ascension will provide Google with personal health datasets to develop Artificial Intelligence-based tools for medical providers. This alliance, named “Project Nightingale” was announced one week after Google bought Fitbit for $ 2.1 billion. The announcement of the partnership confirms the earlier reports that Google is working on a search tool for doctors to find medical records easily. The deal of sharing data Google will be acquiring detailed personal health data of people across the US, which would include patient names, dates of birth, doctor diagnoses, lab results, and hospitalization records, along with the medical histories of 50 million patients of Ascension. Google confirmed that it would abide by the HIPAA regulations to protect the privacy and security of the patients. According to the HIPAA regulations, hospitals can share the patient data with its business partners without the consent of patients on the condition that the data will be used only
for clinical purposes.
for personalized healthcare.
Google stated that the data from Ascension would not be used for any purposes other than the mentioned services, and they will not be combined with the Google consumer data.
This is not the first time Google is interested in the health sector. Google has close relationships with other health institutions like the Chilean Health Ministry, Mayo Clinic, Dr. Agarwal’s Eye Hospital, as well as the American Cancer Society.
It is noteworthy that Ascension is not paying Google for these services. They believe that the application of Artificial Intelligence will improve the quality of the health sector by developing machine learning models
Still, there are queries concerning the privacy of patients considering that 150 employees of Google will have access to these medical records.
That’s not all! In 2016 Google was accused of violating patient privacy for DeepMind health move after it’s a partnership with Britain’s National Health Service regardless of it’s earlier vow to keep the health industry separate. Despite the privacy concerns, let’s hope that this initiative by Google would improve healthcare immensely.

Guide For Becoming a Programming Biologist Have the idea of becoming a biology programmer ever stricken your mind? Is it so that you tried but later found yourself standing nowhere near to start? If the answer to both of these questions is yes, you are encouraged to give a try to the following resources. COMPUTER SCIENCE IS ONE OF THE SUBJECTS WHICH NEEDS LEAST CERTIFICATION AND GUIDANCE AND MORE OF SELF-LEARNING AND PRACTICE, ALONG WITH MOTIVATION AND A COMPUTER CONNECTED TO THE INTERNET! By Dr. Preeti Saini
brary of tools. To name a few Biopython, Galaxy, and Pygr. Python is also smoother to implement in a relatively shorter amount of time, as compared to C++ or Java. If you’re unsure which program is right for you, do some research online, Spend some time reading up on the different pros/cons of the languages you have filtered as well as how steep the learning curve is. One can always learn multiple languages. However, it is advisable to master the first language before setting out to learn a second. Don’t Hurry It, Take Baby Steps! Once you’ve begun, specialize in one task at a time and apply your thinking and problem-solving expertise. This needs tackling a problem stepwise. Analysis of the overall information could sound challenging, however taking the baby steps will help a lot. e.g., First scan your information, decide on a way to interpret missing values, do the scaling, establish comparison conditions, calculate fold change, etc. Tackle these tasks one at a time. Iteratively edit for potency, flow, and conciseness. Don’t be afraid of committing mistakes, the more important thing is to notice, correct, and learn from them. Immersion Is The Best Learning Tool Do not sew along an analysis by shifting between or among languages, this is going to make the task more
difficult. If possible, complete the job in one language or environment. Like, importing a spreadsheet of data (like you would view in Excel) is not necessarily straightforward; Excel automatically determines how to read a text, but the method may differ from conventions in other programming languages. If your date is not being read properly (misread), it is suggested to take the help of Excel. However, these issues are fastened by correctly reading the information and by understanding the language’s data structures. Additionally, transferring across programs induces error. See References for additional Excel or word processing–induced errors. Eventually, you’ll establish tasks that don’t seem to be well matched to the language under consideration. At that time, it should be helpful to choose can build will make it easier to find out a second. Practice Makes Perfect Once you’ve started onto something, what comes next is relentless practice. Like any other field – a Programming Biologist career will also take lots of practice of constantly writing programs is going to make you perfect in this particular field. I hope you have learned of the famous fact “if you are going to spend 10,000 hours onto the subject of your choice, it will make you a Master of the same”. While doing the same, you’ll be handling certain small techniques, learning to think programmatically, and will eventually feel confident enough to
apply your knowledge to real-world issues. Take Help There may be a whole lot of online resources in the form of documentation, sites, and tutorials as well as the communities to discuss the problems viz. Biostars, StackExchange, StackOverflow, etc., but nothing can substitute for a friend or colleague’s help. You may find one in your own university. If your lab or university does not have a community of programmers, take the help of certification courses online. Thereby, it will also be possible to get mailing lists for connecting with members. One can also get in contact with the help of events organized by language-specific user groups or interest groups focused on big data, machine learning, or data visualization in one’s city. But before asking for help as well, you need to be clear about the problem yourself. First, interpret the error message. The process of understanding the problem is called “debugging”. Before starting the work go through previous papers, check experiments, get code from your friends, implement and interpret that code, discuss your queries with them, take their help in editing.

How To Make A Career in Next Gen Sequencing? Current DNA sequencing methods cannot differentiate between the 2 states of genes i.e; when they are turned on or off. THE NEXT GEN SEQUENCING TECHNOLOGIES CAN DIFFERENTIATE BETWEEN THE SAME. By Dr. Ankita Trivedi
With the help of this technology, we can accurately identify cures for diseases !! There were certain misconceptions and drawbacks of Sanger sequencing methods that laid the foundation of these new and much more advanced sequencing technologies collectively termed as NEXT GENERATION SEQUENCING. What is Sequencing? You all are aware of the fact that our body is made up of DNA – A Hereditary material. DNA is made up of a nucleic acid sequence. In order to determine the nucleotides in DNA, sequencing was performed. Sequencing includes any method or technology that can be helpful in any way to determine and analyze the order of the four nucleotide bases: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). DNA sequencing is mostly performed by using the Chain Termination method of Frederick Sanger. This was the simplest technique that implies sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates. Nevertheless, certain new technologies of sequencing are acquiring a high share of the sequencing methods. Pyrosequencing is one of those that is generating more genome data than Sanger DNA sequencing method/technology. What is NGS- Next Gen Sequencing? Next-gen sequencing alludes to non-Sanger-based high-throughput DNA sequencing technologies. Many strands, almost Millions or billions of DNA strands can be sequenced in parallel, generating substantially more throughput and minimizing the need for the fragment-cloning methods that were used for Sanger sequencing of genomes. NGS has transfigured nearly most of the area of Biotechnology. NGS allows the sequencing of nucleic acids like DNA and RNA much more quickly and in a cheaper man-
ner than the older version of sequencing technologies. With the use of these technologies study of various branches of Biology such as Genetics and Molecular Biology are revolutionized. Next-gen sequencing includes different types of sequencing methods. Let’s have a look at these Sequencing methods and how they are far ahead from Sanger-based sequencing technology. NGS utilizes vast numbers of short reads that are sequenced in a single stroke. To achieve this, the input sample is first chopped down into short sections. The various section lengths produced will depend on the fact that which particular sequencing methodology has been used. Based on this NGS can be of three types described below: Illumina (Solexa) Sequencing: This method works by simultaneously analyzing DNA bases as each base emits a unique fluorescent signal, and adding them to a nucleic acid chain. In this method: 100-150 bp reads are used. Longer fragments are ligated to generic adaptors which are then annealed to a slide with the help of adaptors. To amplify each read and to produce a spot with multiple copies of the same read, PCR is used. In the final step, multiple copies are split into single strands that are subjected to sequencing. Roche 454 Sequencing: The second type of NGS is based on pyrosequencing that notices the release of
pyrophosphate once nucleotides are subsumed by polymerase to a new DNA strand with the help of fluorescence. This method can sequence much longer reads than Illumina (up to 1kb), but the sequencing method remains the same. The read ends are attached to generic adaptors and are annealed to beads. Finally, PCR is used to amplify these fragments by adaptor- specific primers. Each well of a slide contains a single bead covered in multiple PCR copies of a single sequence in addition to Sequencing buffers and DNA polymerase. Ion Torrent: Proton / PGM sequencing: This NGS method is unique in its own way. This sequencing method measures the direct release of H+ by the incorporation of individual bases / dNTP by DNA polymerase and thus shows the difference from the previous two methods as it does not measure optical signals. In this method, the read size is about 200bp. Adaptors are added and a molecule is deposited on a bead. With the help of emulsion PCR, molecules are amplified. Single well on a slide contains a single bead. Applications of NGS : Next-Generation Sequencing has an allied group of applications. With the advancement in various sequencing methods, the way to carry out various studies on molecular and genomic levels has been changed and modified. NGS has given us so much power to sequence and interprets genomes quickly and accurately. NGS is used to study various variations,
DNA-binding as well as expression at a genome-wide level. With more advancement based on various research studies, one can get an idea of the immense potential of Next Gen Sequencing in numerous fields and the different tools that can be used for the analysis purpose. Some of the Applications of NGS are listed below : • Next generation sequencing techniques are applied to different aspects of Biological Sciences such as Plant Biotechnology, Animal Biotechnology, and Human Biotechnology. • The plentiful information generated by NGS assists in analyzing genomic variations, various disease mechanisms, and its resistance. • NGS has its applications in forensic genetics- NGS contributes to offering new possibilities for forensic genetic casework. • This method of sequencing can be combined with various types of markers like STRs, SNPs, insertion/deletions, mRNA -to gather more information from unique samples in a single experiment. • All these sorts of applications of Next generation sequencing help

Medical Writing As A Career – Eligibility & Job Prospects If you master those writing skills which can leave the readers into a state of contentment where the most complicated fact or data is explained in a technical but tranquil language, this exhilarating career of medical writing might be waiting for you. NOT ONLY THIS CAREER OPTION HAS TOUCHED THE HEIGHTS DURING RECENT YEARS IN TERMS OF PROVIDING CAREER OPTIONS BUT ALSO IT IS OFFERING ALLURING SALARY PACKAGES TO THE EMPLOYERS. By Dr. Nidhi Hukku
What is medical writing and what does it contribute? Medical writing is an art of creating well-articulated scientific documents that may include clinical research documents, content for healthcare websites, health magazines, health care journals, and health-related news. It also encompasses writing documents for clients in media, industries, government, clinical research organizations (CROs) and medical device manufacturers. The Two arms of Medical writing! Medical writing can be broadly categorized into regulatory medical writing and Educational medical writing. 1.Regulatory medical writing: Contributes to getting the approval of drugs/cosmetics/food products/ medical devices! This form of medical writing involves writing the documents that are required to be submitted to the regulatory agencies to get approval for drugs, devices, and biologics. Usually, each country owns its national authority whose approval is required for medicine, drug, cosmetic products, processed food, biologics to be marketed and sold. Regulatory documents remain huge and are required to be created complying with the standards of technical writing. For drug approval, regulatory documents comprise of all the details and data initializing from the clinical trials. These documents include clinical study protocols, clinical study reports, patients’ consent forms, investigator brochures and the most significant Common Technical Document [CTD] in prescribed formats. These documents are created to summarize and interpret the data gathered by the
company in the course of developing a pharmaceutical or cosmetic product. The audience for these documents remain ethical committees and regulatory authorities.
2. Educational medical writing: Assists in facing the general audience! Any information which has been collected from various sources and shaped in the form of the technical regulatory documents, when needs to be presented to the general audience or health care professionals should be done in a captivating and illuminating manner. Addressed for the general public, these documents are written in simple, non-technical language. This subset of medical writing helps in developing drug-related educational and propagative literature, journal manuscripts, abstracts. Besides, writing content for healthcare-related journals, newsletters, magazines and healthcare websites will share canopy under educational medical writing. What a medical writer does? • A medical writer creates, proofreads, finalizes protocols, investigator brochures, synopses, regulatory documents, and clinical documents. • A medical writer contributes to the development of product dossiers for a company aimed at regulatory authority submissions. • A medical writer coordinates with clinicians, clinical scien-
tists, biostatisticians, and pharma professionals to transcribe study results. A medical writer ensures clinical or research studies results and statistical interpretations are precisely reflected in the final documents. A medical writer works in collaboration with scientists, doctors and subject matter experts to design and outline the framework for the essential documents. A medical writer helps doctors or a medical organization to write research articles, abstracts, reviews and monographs on health-related topics. A medical writer works for a pharmaceutical or medical device manufacturing company to design educational materials and informational material for kits or package inserts to be used by the doctors and the nurses. A medical writer may produce documents for the press release for a company or website content for it. A medical writer writes about the research discoveries for any medium or means to reach the general public. A medical writer fortifies that medical writing documents comply to International Conference on Harmonization(ICH) or other relevant regulatory guidelines A medical writer develops standard operating procedures for the preparation and maintenance of compliant medical writing deliverables for a company.
• A medical writer inspects that appropriate documented quality control (QC) checks are being implemented on medical writing deliverables. Where medical writers could be placed for Job? Nowadays Medical Writing Career is booming, demand for medical writers is tremendously growing. Medical writers could find a job option in an array of niches like: • CROs( Contract Research Organizations) or BPOs and KPOs • Functional service providers i.e companies involved in Scientific content and healthcare communication • Media & Publishing companies • Reputed Medical Journals • Academic medical institutions engaged in providing education to healthcare professionals. • Medical/scientific societies • Pharmaceutical/healthcare product companies including medical device companies • Food processing/ cosmetics manufacturing companies • Healthcare Websites Top Companies Hiring Medical Writers: • Paraxel • Novo Nordisk

Overpopulation – The Human Explosion Explained
Humans are considered as the most powerful species on earth. They are the most intelligent and have the power to control everything that exists on earth. But what, if we tell you, that this super-intelligent human race is controlled by tiny organisms that live within or exists inside the human body. They not only influence the human brain but behavior too.
Episode 56 By Dr.Tanushree
Scary right! Welcome to the next episode of Voice of Biotecnika, where we will tell you about who these tiny organisms are and why as well as how these tiny organisms control humans or more precisely “RULE OVER YOUR BODY”. Bacteria are everywhere, the air you breathe, the water you drink, food that you eat, on and inside your body, things you use like mobile phones, laptops, tabs, even washed clothes as well as utensils, everywhere, you can think about it. In recent years, the term “microbiome” has sought the attention of researchers and scientists all-round the globe. So you must be thinking what is this Microbiome? Microbiome describes the genome of all microorganisms including bacteria, viruses, fungi and archaea in a particular environment, like the microorganisms in our gut environment are known as the gut microbiome. These microbes can be symbiotic or pathogenic, living in and on all vertebrates. Talking about bacteria in the gut, these are key to many aspects of human health including metabolism, immune, and neurobehavioural traits which have been supported by evidence from the animal models and human studies. But how our relationship with these bacteria begins? It is assumed that humans develop their relationship with bacteria inside the mother’s womb. The innumerable bacteria present inside the mother’s womb, cover every single part of our body. Pregnant mothers release some molecules that make their way in the fetal brain and seed their babies with these microbes during childbirth. After birth, special sugars that are present inside the mother’s milk feed and support these bacteria. During the first few years of infant life, both the brain and microbe rapidly develop. These bacteria help in the development of our immune system and develop a healthy community inside
the human body. Once the solid diet is introduced to babies, it becomes an important factor that has a stronger impact on subsequent maintenance and maturation of gut microbiota organization throughout the lifespan. These bacteria are considered to play an important part in human health, therefore, our body not only accepts their invasion but we also welcome it. What does this gut microbiota do for us? There are several categories of bacteria inside our bodies. There are some whom we learn to live, the one which is present in our mouth and can harm our teeth if we do not brush daily. Next is, friendly fellows who live in our gut. The bacterial microbial communities present in the human gut are essential for maintaining the intestinal ecosystem as well as play an important role in gathering energy from foods and producing micronutrients. The gut microbiota performs fermentation of non-digestible substrates like dietary fibers which in turn supports the growth of short-chain fatty acids and gases producing microbes. Several enzymes produced by these gut microbes contribute to the metabolism of bile acid that acts as metabolic regulators and signaling molecules to affect important pathways in the host. In return, we provide food to them and an appropriate environment for growth. Thus, we not only live with them but also depend on this vast army of bacteria to stay alive. Every human has a distinctive mi-
crobiome. In the last few years, understanding of the influence of gut microbiome goes much deeper. The gut microbiome is considered an area of great assurance for a better understanding of human health and related diseases. It is considered that the bacteria that are part of our microbiome encodes millions of genes that can manufacture thousands of metabolites, which has the potential to replace many of the functions in the host which affect the host’s phenotype, fitness, as well as health. Whether it’s a craving for a specific food, immune system protection, regulation of behavior or role in several disorders such as depression, autism, dementia, and many others, in all these, our body’s bacterial community plays a very important role. Therefore, the microbiome is now considered a virtual organ of the human body. So, how do these microbiomes communicate with us? There are several pieces of evidence that indicate the human immune system and microbes communicate with each other and produce a specific response. Different disease results in changing of the composition of these bacteria in the gut. Several researchers are working on how our body’s immune system interacts with these tiny travelers and how that relationship may function in a particular disease. For example, certain bacteria that are present in the lining of the gut excrete excessive quantities of antibodies into the gut, which can help in understanding what are the antibodies
types being made, and how the body tries to regulate the interaction between ourselves and bacteria on the outside. It is interesting to know that microbes can even talk to our brain, they not only interact but affect our nervous system or maybe our mood too. In the gut, several neuroactive compounds are synthesized which have a major impact on mental well-being. Studies have reported the production of DOPAC, a metabolite of the neurotransmitter dopamine in humans is related to the healthier mental quality of life. Dopamine and serotonin have composite roles in the brain and imbalances related to it. About 90% of serotonin which is an important messenger for the immune system, produced in the gut. Scientists believe that the microbiome does this to communicate with the vagus nerve, which connects about 100 million nerve cells from the digestive tract to the base of the brain. The vagus nerve sends these signals from the gut to the brain, where they alter the production of a hormone called oxytocin that promotes social bonds. Some chemicals communicate through the bloodstream with the brain. Since the brain decides what to eat, the microbe is interested in a healthy brain. Bacteria in the gut have the ability to manage behavior and mood through altering the neural signals in the va-

gus nerve, changing taste receptors, producing toxins to make us feel bad, and liberating chemicals to make us feel good. However, the microbes, that live outside the human body, like those present in the soil are not able to synthesize some kind of neurotransmitters. The reason might be that these microorganisms have not co-evolve with humans and therefore, have not learned to gain advantage from invading into the host nervous system. Although there is a heritable part of gut microbiota, several environmental factors such as related to diet and drugs decide the composition of gut microbiota which in turn can affect our health. Antibiotics entered indirectly in our body through the food chain have various metabolic consequences that vary from person to person. Antibiotics are used for livestock farming in many countries. Several human studies, as well as many rodents studies, have provided an obesogenic effect of antibiotics in humans in minute doses found in food. Therefore, extensive research on the gut microbiome is required to better understand the effect of antibiotics, chemicals such as pesticides sprayed on crops on them. Several animal studies have shown that sugar substitutes such as aspartame, sucralose as well as saccharin and food additives such as emulsifiers which are present in processed food have negative effects on the animals’ gut microbiota. The production of trimethylamine from carnitine and dietary phosphatidylcholine (dairy and meat products) by gut microbiota varies between people depending on the food they consume. This trimethylamine oxidized in the liver to trimethylamine N-oxide, which is associated with an increased risk of atherosclerosis (buildup of plaque inside arteries) and major adverse cardiovascular events. Some people follow restrictive diets like raw food, the vegan, gluten-free diet which may also raise some concern as these may have some side-effects on gut health. So, there is a strong relationship in what you eat decides what type of bacteria you breed or what type of bacteria present in your body decides what to eat. These microbes initially come from our mother but how they develop and change depending on what we eat. For example, some bacteria like fibers whereas some like cheese. If we eat a lot of fast food we breed fast food-loving bacteria that take up space for vegetable eating bacteria and also send signals to the brain
to eat fast food. Thus, gut microbiota seems to play an important role in the development and progression of obesity. So we can reverse fast food or cheese liking bacteria with vegetable liking or fiber good bacteria and this intensifies the strong connection between diet and microbiome. Also, it’s not just about the bacterial numbers but their diversity too. It has been observed that the people suffering from inflammatory bowel disease, type 1 or 2 diabetes, obesity, and atopic eczema have lower bacterial diversity than in healthy individuals. This indicates that the gut ecosystem which is rich in microbe species is more robust against environmental influences. If any microbe species is missing, its function is been performed by a more related microbe. Thus, “diversity” seems to be a good indicator of a “healthy gut”. However, an increase in dietary fiber or a specific type of diet may temporarily reduce the diversity as the microbes related to digestion of fibers increases, leading to change in a composition via competitive interactions. It has been reported that the people who lack certain bacteria in their gut are more likely to undergo depression. Studies have provided evidence that the bacteria Dialister and Coprococcus, were uncommon in depressed people. It might be possible that the people suffering from depression may have different eating habits that have led to changes in their gut flora, resulting in their low levels and in turn responsible for depression. Some researchers also believe that bacteria living within our bodies may cause stomach or other cancers. Thus, the evolution of tumors and bacterial communities are linked. There are several pieces of evidence where minor changes in microbiota can result
in major changes in immune-chemotherapy treated cancer patients, autoimmune disorders and bone marrow recipients. For example, studies have shown that phytoestrogens have a protective effect on breast cancer which depends on the presence of several intestinal bacteria such as Lactonifactor longoviformis, Clostridium saccharogumia, and Blautia producta, Eggerthella lenta that can convert isoflavones into bioactive compounds. Targeting the microbiome, there is a possibility for preventing a variety of diseases such as diabetes and gastrointestinal tract cancers. The treatment is possible by using probiotics that increase the populations in gut treatment. Probiotics are live microorganisms that when given in an appropriate amount have health benefits on the host. Among probiotics, mostly Lactobacillus species and Bifidobacterium species are included in of products such as dietary supplements, drugs, and food. There are concerns that most microbe supplements are unable to set themselves in the gut and in turn, do not exert any effect on the resident community. However, they have a direct effect on the host through the production of bioactive compounds or immune modulation. But, prior to probiotic treatment, it is important to know about the substances synthesized by these bacteria followed by their testing. This is a challenging task as this diverse and complex bacterial community of gut microbiome keeps on changing during different stages of life. The human microbiota undergoes the most prominent fluctuations during infancy and old age. This is the time when our immune health is most unstable and weakest. The elderly people have different bacterial gut microbiota profile than healthy adults. There are ev-
idence that suggests, the association of gut microbiota with age-related chronic conditions of health and inflammation, and hence could be exploited as a presumed target to improve the aging process. Understanding the functional role of the human gut microbiome, the researchers have come up with fecal microbiota transplantation. It’s not yet clinical practice but has been explored where feces from a healthy donor is transplanted to recipients with metabolic syndrome resulting in better insulin sensitivity. Fecal microbiota transplantation (FMT) provides support in the treatment of recurrent Clostridium difficile infection with cure rates reported up to 90% in clinical trials. However, the FMT use in other conditions such as obesity, inflammatory bowel disease, metabolic syndrome, and functional gastrointestinal disorders is still controversial. Thus, more studies are required to fill in gaps in understanding microbiome composition, function and bacterial prebiotics, probiotics or fecal microbiota transplantation to assess changes in microbiota composition and in health outcomes. The extensive catalog of human gut bugs will help scientists to recognize the specific bacteria in patients’ bodies and lead research into new treatments for conditions such as psychiatric, neurological, allergies, obesity, aging, bowel syndrome and many disorders. So, now you might have understood better, that your diet plays an important role in the development of healthy bacteria inside your body. Your microbiome not only indicates what is going inside you but also keeps you healthy as well as happy, because after all it’s not you but your “microbiome- that rule over your body”.
