<ul>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">In this fuel cell, carefully selected cohort of bacteria is made to act on the textile wastewater placed in it. These bacteria are isolated from very wastewater they are meant to degrade. </span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">They feed on organic material in water and break it down under anaerobic (without oxygen) conditions, releasing electrons in process. </span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The electrons are collected at anode which results in current in circuit. The bacteria forms biofilm on anode making collection of electrons easy at anode.</span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">During this entire process, bacteria act on wastewater and purify it and waste is segregated in the cell. For example, dye present in wastewater is broken to simpler form.</span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">At present this technology has been tested in 200 litre capacity prototype, which can can generate power of around 1 watt per square-metre.</span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Scientists are also incorporating nanotechnology in it, to add nanotech filter to improve process to keep thickness of biofilm within prescribed limit.</span></span></li>

This gene links sleep to immune system and provides potential explanation for how sleep increases during sickness. It was identified in study of over 12,000 lines of fruit flies. It was found that to extent of infection, stimulated overactive nemuri expressed in small set of fly neurons improves sleep.</span></span></p>
<p style="margin-left:0in; margin-right:0in; text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong>Key Findings of Study</strong></span></span></p>
<ul>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Nemuri gene fights germs with its inherent antimicrobial activity and drives prolonged, deep sleep after infection.<strong>It provides potential explanation for how sleep increases during sickness</strong></span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">It was found that flies with extra nemuri were better at fighting flu. When they were infected with deadly bacteria, nemuri-boosted flies survived longer than their non-boosted counterparts.</span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">In response to infection, nemuri gene kill microbes, most likely in peripheral parts of fruit fly body and increased sleep through its action in the brain.</span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Abundance of nemuri also helped flies fight infection, thus presents clear connection between this sleep gene and immune system.</span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">It was also found that flies lacking nemuri gene, were completely unable to manufacture its antimicrobial benefits.</span></span></li>
<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">However, nemuri gene is not all gene required for sleep or immunity. Without it, flies are still capable of sleeping, albeit more fitfully, and its absence doesn’t impair them in resisting infection.</span></span></li>

<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><span style="font-family:"quicksand",serif">This is caused by specific enzyme (LTA4 hydrolase) being switched off by mycotoxin.

<li style="text-align:justify"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><span style="font-family:"quicksand",serif">Healthy people are not affected much if spores of this fungus find their way into their body.

<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The three kits developed are TB Detect, TB Concentration & Transport, and TB DNA Extraction.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The TB Detect kit is for diagnosis using LED fluorescence microscopy, while the TB Concentration & Transport, and the TB DNA Extraction kits together are for detection of drug-resistance.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The TB Detect kit helps increase the positivity of LED fluorescence microscopy by about 5%, while the TB DNA Extraction kit allows the detection of drug-resistant TB bacteria with a high level of sensitivity. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">TB detection kit uses a simple filter-based system to separate TB bacteria from the sputum to improve the sensitivity of LED fluorescence microscopy. In this, the sputum, which is viscous, is first liquefied using a proprietary reagent and pre-filtered. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The liquefied sputum containing the TB bacteria then comes in contact with a highly porous, plastic membrane filter made up of multiple fibrous pads kept at the base of the filter device.

</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The membrane concentrates the bacteria in a small surface, which is about 1 cm in diameter. This leads to an increase in the detection limit by separating the bacteria from sputum.</span></span></p>

<p style="margin-right:0cm"><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">A novel amylase-based biocatalyst developed by researchers at the Central Leather Research Institute (CSIR-CLRI), Chennai, helps in processing leather in an environment-friendly way and also drastically cutting the time taken to process the skin at the pre-tanning stage.</span></span></p>
<p style="margin-right:0cm"> </p>
<p style="margin-right:0cm"><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif""><strong>Background</strong></span></span></p>
<p style="margin-right:0cm"><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">Pre-tanning process generates 60-70% of total pollution during processing. This pollution is responsible for polluting water bodies and their ecosystem. The new discovery can lead to reduction in water pollution.</span></span></p>
<p style="margin-right:0cm"> </p>
<p style="margin-right:0cm"><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif""><strong>Details</strong></span></span></p>
<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">In the new proceess using bio-catalyst ,the quantum of effluent discharge is considerably cut as there is threefold reduction in water usage.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">Chromium, that is used for increasing the stability of the collagen through cross-linking is less utilised. Since no chemicals are used, the chemical oxygen demand drops by about 35% while the total solid effluent load reduces by over 50%.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">The reason why less chromium and water are required at the pre-tanning stage when the biocatalyst is used is primarily because of the 120-fold higher binding of the biocatalyst to the glycan sugar present predominantly in the skin.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">Once the catalysts binds to the sugar, it selectively breaks down (hydrolysis) the sugar thus opening up the skin fibre without much effort.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">Traditionally, enzymes take three-to-four hours to open the fibres. If lime and sulphate are used it takes 12 hours to complete the process. Using Bio-catalyst reduces the time required to 10 minutes.</span></span></p>
</li>
</ul>
<p style="margin-right:0cm"><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif""><strong>Importance of Biocatalyst discovery</strong></span></span></p>
<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">The biocatalyst also penetrates deep into the skin unlike the traditionally used enzymes. Deep penetration of the biocatalyst ensures less amount of chromium to be used to increase the stability of the collagen and the quality of the finished leather also becomes superior.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">About 21% of the chromium used gets absorbed by the skin, which is far more than when other enzymes or chemical-based methods are used, leading to reduced chromium in the effluent discharge.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">The biocatalyst is stable even at a high temperature of 90 degree C and pH 10 and so up to 95% of the enzyme can be recovered after a single process and reused.</span></span></p>
</li>
</ul>
<p style="margin-right:0cm"><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif""><strong>Additional Information</strong></span></span></p>
<p style="margin-right:0cm"><span style="font-size:11pt"><span style="font-family:"Calibri","sans-serif"">Biocatalysis refers to the use of living systems or their parts to speed up chemical reactions.

</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">NIV isolated a strain of the virus from an asymptomatic Covid-19 patient and transferred it to BBIL early in May. The firm then used it to work on developing an “inactivated” vaccine–a vaccine that uses a dead virus.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Once the vaccine is injected into a human, it has no potential to infect or replicate, since it is a killed virus. It just serves to the immune system as a dead virus and mounts an antibody response towards the virus.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">BBIL’s Covaxin then underwent pre-clinical testing, when the vaccine is tested on animals like guinea pigs and mice to see if it is safe, before the firm approached CDSCO for approvals to move on to the next stage of testing–human trials.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The first phase, usually conducted on a small group of individuals, tries to find what dosage of the vaccine is safe for use, whether it is effective in building their immunity to the virus and whether there are any side effects. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The second phase is conducted on a larger group comprising hundreds of persons fitting the description of those for whom the vaccine is intended using characteristics like age and sex.

<p style="margin-right:0cm"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The study said that across all populations, the candidate was well-tolerated and demonstrated a strong immune response, and that they are on track to seek regulatory review in October 2020.</span></span></p>

<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The project with four vaccine candidates is based on BionTech’s proprietary mRNA-based technology platforms. It began in mid-January after the genetic sequence of SARS-CoV-2 was made public.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Two of these four candidates — BNT162b1 or BNT162b2 — have gone into human trials so far. Both are in Phase 1/2 human trials in the United States and Germany.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The researchers announced that after extensive review of preclinical and clinical data and in consultation with the US FDA’s Center for Biologics Evaluation and Research, they have chosen to advance their BNT162b2 vaccine candidate into the Phase 2/3 study, where 30,000 participants will be taking part.</span></span></p>
</li>
</ul>
<p style="margin-right:0cm"> </p>
<p style="margin-right:0cm"><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif"><strong> BNT162b2</strong></span></span></p>
<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">It is a single nucleoside-modified messenger RNA (modRNA) vaccine candidate. It is made of a short segment of genetic material — the messenger RNA — which provides instructions for a human cell to make a harmless version of a target protein, in this case the spike protein of SARS-CoV-2, in order to activate an immune response against the protein.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">During a clinical trial, three aspects are assessed: reactogenicity (ability to produce common, adverse reactions), immunogenicity (ability to provoke an immune response), and safety.</span></span></p>
</li>
<li>
<p><span style="font-size:11.0pt"><span style="font-family:"Calibri","sans-serif"">BNT162b2 was associated with less systemic reactogenicity, particularly in older adults. This effectively means that BNT162b2 generates an even lower adverse reaction among the vulnerable population, making it the safer candidate of the two.</span></span></p>

<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Last week, the World Health Organisation cautioned Russia against rushing through with its vaccine as officials expressed doubts over the shots being produced in China and Russia during testifying before a panel of US lawmakers.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Russia’s vaccine is based on the DNA of a SARS-CoV-2 type adenovirus, a common cold virus. The vaccine uses the weakened virus to deliver small parts of a pathogen and stimulate an immune response. Officials maintained that the coronavirus particles in the vaccine cannot harm the body as they cannot multiply.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">So far, Russia has only made public the results of phase-I of the clinical trials, which they claimed were successful and produced the desired immune response. </span></span></p>

<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Phase I human trials started on June 17 among 76 volunteers, with most being recruited from the military.

</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The superfast speed at which the Russian vaccine has been produced, eclipsing front runners like Oxford-AstraZeneca, Moderna, and Pfizer, has led to experts flagging that the government has cut corners and may put citizens at risk.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">What has raised the issue from experts is the fact that human trials for the vaccine, which takes several years in normal circumstances, have been completed in less than two months.</span></span></p>
</li>
<li>
<p><span style="font-size:11.0pt"><span style="font-family:"Calibri","sans-serif"">Russia, however, has claimed that this was made possible due to the fact that its Covid-19 vaccine candidate closely resembled a vaccine for Middle East Respiratory Syndrome (MERS) disease, caused by another coronavirus, that had already been tested extensively.</span></span></p>

<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">But it has certain shortcomings. The test requires complex and costly equipment. It requires extensive training for potential users.</span></span></p>

<ul>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The RT-PCR test needs different temperatures in one cycle.

<li>

<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The quantity of DNA amplified in the LAMP technology is hundred thousand times more than that is taking place in PCR. </span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The assay is so fast that results can be obtained within 30 minutes and positive samples are amplified as early as 10 minutes.</span></span></p>
</li>
<li>
<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">Another advantage of LAMP is that the reagents are to be stored at 4 degree C (ordinary fridge), whereas the PCR-based reagents are to be stored and transported at –20 degrees C, which needs deep freezers that escalate the cost.</span></span></p>
