"Long COVID": More than a quarter of COVID-19 patients still symptomatic after 6 months

In a new study of adults from the general population who were infected with COVID-19 in 2020, more than a quarter report not having fully recovered after six to eight months. Those findings are described this week in the open-access journal PLOS ONE by Milo Puhan and colleagues at the University of Zurich, Switzerland.

Artificial intelligence could be new blueprint for precision drug discovery

Writing in the July 12, 2021 online issue of Nature Communications, researchers at University of California San Diego School of Medicine describe a new approach that uses machine learning to hunt for disease targets and then predicts whether a drug is likely to receive FDA approval.

Anti-tumor agent from the intestine

It is believed to be involved in the development of chronic inflammatory intestinal diseases, to trigger diabetes, to be responsible for obesity, even neurological diseases such as multiple sclerosis and Parkinson's could have their causes here - not to mention depressions and autistic disorders. We are talking about the microbiome - the vast collection of bacteria in the human gut. It is estimated that each person carries around 100 trillion bacterial cells in their digestive tract, belonging to several thousand species.

mRNA vaccines slash risk of COVID-19 infection by 91% in fully vaccinated people

People who receive mRNA COVID-19 vaccines are up to 91 percent less likely to develop the disease than those who are unvaccinated, according to a new nationwide study of eight sites, including Salt Lake City. For those few vaccinated people who do still get an infection, or "breakthrough" cases, the study suggests that vaccines reduce the severity of COVID-19 symptoms and shorten its duration.

Cancer cells eat themselves to survive

It is the membrane of cancer cells that is at the focus of the new research now showing a completely new way in which cancer cells can repair the damage that can otherwise kill them.

In both normal cells and cancer cells, the cell membrane acts as the skin of the cells. And damage to the membrane can be life threatening. The interior of cells is fluid, and if a hole is made in the membrane, the cell simply floats out and dies - a bit like a hole in a water balloon.

Researchers find potential path to a broadly protective COVID-19 vaccine using T cells

Gaurav Gaiha, MD, DPhil, a member of the Ragon Institute of MGH, MIT and Harvard, studies HIV, one of the fastest-mutating viruses known to humankind. But HIV's ability to mutate isn't unique among RNA viruses - most viruses develop mutations, or changes in their genetic code, over time. If a virus is disease-causing, the right mutation can allow the virus to escape the immune response by changing the viral pieces the immune system uses to recognize the virus as a threat, pieces scientists call epitopes.

Mefloquine: A promising drug 'soldier' in the battle against COVID-19

Early 2020 saw the world break into what has been described as a "war-like situation": a pandemic, caused by the severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), the likes of which majority of the living generations across most of the planet have not ever seen. This pandemic has downed economies and resulted in hundreds of thousands of deaths.
