A team HKUST scientists has recently identified a set of potential vaccine targets for SARS-CoV-2 coronavirus, to guide experimental efforts towards vaccine development against novel pneumonia (COVID-19).
Resistance to a deadly disease that is affecting the second most farmed fish in the world has been found to be mainly due to differences in genes between families of the same fish. The breakthrough could help protect stocks of Tilapia fish, which is an important food source in Africa, Asia and South America and worth nearly $10 billion to the global economy.
In a compelling article in Progress in Cardiovascular Diseases, published by Elsevier, Mark McCarty of the Catalytic Longevity Foundation, San Diego, CA, USA, and James DiNicolantonio, PharmD, a cardiovascular research scientist at Saint Luke's Mid America Heart Institute, Kansas City, MO, USA, propose that certain nutraceuticals may help provide relief to people infected with encapsulated RNA viruses such as influenza and coronavirus.
Interacting contagious diseases like influenza and pneumonia--and perhaps coronavirus too -- follow the same complex spreading patterns as social trends, like the adoption of new slang or technologies. This new finding, published in Nature Physics, could lead to better tracking and intervention when multiple diseases spread through a population at the same time.
Egypt, Algeria and Republic of South Africa are the African countries most at risk for coronavirus COVID-19 importation in the continent, due to high air traffic with the contaminated Chinese provinces. But these countries are also among the best equipped on the continent to quickly detect and deal with new cases. In other African countries, the risk of importation is lower, but health organization deficiencies raise concerns about rapid spread.
Increased resources, surveillance, and capacity building should be urgently prioritised in African countries with moderate risk of importing cases of novel coronavirus disease 2019 (COVID-19), as these countries are estimated to be ill-prepared to detect cases and limit transmission.
Researchers have made a critical breakthrough toward developing a vaccine for the 2019 novel coronavirus by creating the first 3D atomic scale map of the part of the virus that attaches to and infects human cells. Mapping this part, called the spike protein, is an essential step so researchers around the world can develop vaccines and antiviral drugs to combat the virus. The paper is publishing Wednesday, Feb. 19 in the journal Science.
Potato virus Y is the most economically important and devastating aphid-transmitted virus, affecting both tuber yield and quality. The virus is also a major cause of seed potato degeneration, which leads to regular flushing out of seed potatoes after limited field production cycles. There is no remedy for this virus and once a plant becomes infected, it stays sick for life.
The 2019 novel coronavirus (CoV) causes fatal pneumonia that has claimed over 1300 lives, with more than 52000 confirmed cases of infection by February 13, 2020, all in the span of just over a month. But, what is this virus? Is it a new virus altogether? Where did it come from? Scientists from top research institutes in China teamed up to answer these questions, and this pioneering study has been published in Chinese Medical Journal.
Northwestern University researchers have, for the first time, determined the 3D atomic structure of a key complex in paramyxoviruses, a family of viruses that includes measles, mumps, human parainfluenza and respiratory syncytial virus (RSV).
