New York, Jul 30: Can the coronavirus spread through the air? Yes, it's possible.

The World Health Organisation recently acknowledged the possibility that Covid-19 might be spread in the air under certain conditions.

Recent Covid-19 outbreaks in crowded indoor settings — restaurants, nightclubs and choir practices — suggest the virus can hang around in the air long enough to potentially infect others if social distancing measures are not strictly enforced.

Experts say the lack of ventilation in these situations is thought to have contributed to spread, and might have allowed the virus to linger in the air longer than normal.

In a report published in May, researchers found that talking produced respiratory droplets that could remain in the air in a closed environment for about eight to 14 minutes.

The WHO says those most at risk from airborne spread are doctors and nurses who perform specialized procedures such as inserting a breathing tube or putting patients on a ventilator.

Medical authorities recommend the use of protective masks and other equipment when doing such procedures.

Scientists maintain it's far less risky to be outside than indoors because virus droplets disperse in the fresh air, reducing the chances of Covid-19 transmission.

New Delhi, Sept 17: Union Health Minister Harsh Vardhan on Thursday said that the coronavirus vaccine will be made available in the country by the start of next year. The remarks come at a time when India is recording more than 50 lakh cases and people are awaiting the vaccine with bated breath.

"Just like other countries, India is also making efforts. Three vaccines candidates are in different phases. Under Prime Minister's guidance, an expert group is looking at it and there is advanced planning in place. We are hopeful that by the start of next year a vaccine will be available in India," Harsh Vardhan said in Rajya Sabha.

Two indigenous vaccines by Zydus Cadila and Bharat Biotech have completed phase 1. Serum Institute of India (SII) has again commenced the trials after getting clearance from the Drug Controller General of India.

India is the manufacturing partner of the vaccine candidate named Covishield, developed jointly by the University of Oxford's Jenner Institute's and AstraZeneca. The Pune-based firm, SII, is looking after the trials at 17 trial sites across India.

Besides this, the Russian Direct Investment Fund (RDIF) and Dr. Reddy's Laboratories Limited, a global pharmaceutical company headquartered out of India, have agreed to cooperate on clinical trials and distribution of Sputnik V vaccine in India.

Sputnik V, an adenovirus vector-based vaccine, was developed by the Gamaleya Scientific Research Institute of Epidemiology and Microbiology, along with the Russian Direct Investment Fund and registered on August 11.

"On regulatory approval in India, RDIF shall supply to Dr. Reddy's 100 million doses of the vaccine. The Sputnik V vaccine, which is based on well-studied human adenoviral vector platform with proven safety, is undergoing clinical trials for the coronavirus pandemic," said a statement from the fund.

New Delhi, Sept 13: A group of scientists in India is working on genomic sequences of SARS-CoV-2 around the World, including India, to identify genetic variability and potential molecular targets in virus and human to find the best possible answer to combat the COVID-19 virus.

As per the Union Ministry of Information and Broadcasting, the study is sponsored by Science and Engineering Research Board (SERB), a statutory body under the Department of Science and Technology (DST) and the study has been published in the Journal called Infection, Genetics, and Evolution.

Breaking down the novel coronavirus challenge into many pieces to get to its root and see it from multiple directions, Dr. Indrajit Saha, Assistant Professor in the Department of Computer Science and Engineering of National Institute of Technical Teachers' Training and Research, Kolkata, and his team have developed a web-based COVID- Predictor to predict the sequence of viruses online on the basis of machine learning and analysed 566 Indian SARS-CoV-2 genomes to find the genetic variability in terms of point mutation and Single Nucleotide Polymorphism (SNP).

"They have mainly found that 57 out of 64 SNPs are present in 6 coding regions of Indian SARS-CoV-2 genomes, and all are nonsynonymous in nature. They have extended this research for more than 10 thousand sequences around the globe, including India and found 20260, 18997, and 3514 unique mutation points globally, including India, excluding India and only for India, respectively," the ministry said.

The scientists are on the track to identify the genetic variability in SARS-CoV-2 genomes around the globe including India, find the number of virus strains using Single Nucleotide Polymorphism (SNP), spot the potential target proteins of the virus and human host based on Protein-Protein Interactions. They also carried out integrating the knowledge of genetic variability, recognize candidates of synthetic vaccine based on conserved genomic regions that are highly immunogenic and antigenic, and detect the virus miRNAs that are also involved in regulating human mRNA.

"They have computed the mutation similarity in sequences of different countries. The results show that the USA, England, and India are the top three countries having the geometric mean, 3.27 per cent, 3.59 per cent, and 5.39 per cent, respectively, of mutation similarity score with other 72 countries," the ministry said.

The scientists have also developed a web application for searching the mutation points in SARS-CoV-2 genomes globally and country wise. Besides, they are now working more towards protein-protein interactions, epitopes discovery, and virus miRNA prediction, it said.

Ludhiana, Sept 18: DMCH Cancer Care Centre in collaboration with American Oncology Institute recently started a new diagnostic service (PSMA-PET Scan) in treating various prostate cancer.

Prostate cancer is the most common cancer in men and one of the leading causes of cancer death. Prostate Specific Membrane Antigen (PSMA ) is highly expressed in prostate cancer and its expression increases with tumour aggressiveness, metastatic disease and disease recurrence.

Secretary of DMCH Managing Society, Sh. Prem Kumar Gupta said, “Very few facilities in the region have this state-of-art facility and will be of great benefit for the patients.” He further added, “DMCH Cancer Care Centre is always in the process of acquiring new techniques and facilities for diagnosing and treating various cancer diseases. The availability of this facility will go a long way to help both patients and clinicians in knowing about the proper stage of prostate cancer, thereby helping patients with better outcome.”

Dr. Puneet Bhutani from the Department of Nuclear Medicine, American Oncology Institute stated, “This is a major milestone in diagnosis of prostate cancer. The procedure of diagnosing prostate cancer through PSMA-PET Scan is more accurate method for early detection of recurrent disease. It allows the oncologists to treat patients at an early stage and provide them a better treatment outcome.”

About American Oncology Institute:

American Oncology Institute is the leading cancer care provider across South Asia operating a chain of cancer hospitals in multiple cities across South Asia. AOI today is a wholly owned subsidiary of Varian Medical Systems (NYSE: VAR).

The team of clinical, paraclinical and healthcare operations experts pride themselves with the aim of closing the gap between standards of cancer care in South Asia and the developed cancer hospitals in the West. AOI provides comprehensive cancer management that is powered by clinical excellence, world class technology as well as best in class clinical pathways and protocols for treatment planning and execution, providing best in-class quality in cancer care across South Asia.
