Individuals infected with mild-to-moderate COVID 19 mount a robust antibody response

The vast majority of individuals infected with mild-to-moderate COVID 19 mount a robust antibody response that is relatively stable for at least five months, according to research conducted at the Icahn School of Medicine at Mount Sinai and published October 28, in the journal Science.

Researchers develop RNA catalyst that sheds light on evolution

Enzymes enable biochemical reactions that would otherwise not take place on their own. In nature, it is mostly proteins that function as enzymes.

Myeloid cell can suppress the immune response to tumor cells

For a long time, researchers had believed that the brain reduces inflammation by protecting itself from an aggressive immune response.

RNA-centric mechanism regulates microRNAs linked to cancer, neurological disorders

MicroRNAs are small non-coding RNAs—that is, bits of genetic code that act as key gene regulators in various aspects of biological processes.

Researchers map molecular structure of CV30 antibody to neutralize coronavirus

Scientists at Fred Hutchinson Cancer Research Center in Seattle have shown that a potent antibody from a COVID-19 survivor interferes with a key feature on the surface of the coronavirus's distinctive spikes and induces critical pieces of those spikes to break off in the process.

Specific metabolites can predict COVID-19 mortality

A new study from Lawson Health Research Institute, Western University and University of Alberta suggests that COVID-19 affects the human body's blood concentration levels of specific metabolites - small molecules broken down in the human body through the process of metabolism.

Proviral and antiviral genes may help develop new therapies for COVID-19

Scientists have screened an unlimited number of cells exposed to the COVID-19 virus and detected genes that appear to close the door on the virus.

Researchers identify genes associated with autism spectrum disorder

The lack of some genes in the BEC/TCEAL cluster could be related to some alterations associated with the autism spectrum disorder, according to a preclinical study published in the journal Genome Biology, and led by Professor Jordi Garcia Fernàndez, from the Faculty of Biology and the Institute of Biomedicine of the University of Barcelona (IBUB), and researcher Jaime Carvajal, from the Andalusian Centre for Developmental Biology - University Pablo de Olavide (CSIC-UPO).

Dual-chip system for monitoring heart toxicity from breast cancer drugs

Breast cancer is the most commonly occurring cancer for women around the world, and much effort has been spent in the development of therapies to treat this disease.

Scientists develop human airway stem cells to accelerate research on COVID-19, influenza

For the first time, researchers have successfully created airway basal stem cells in vitro from induced pluripotent stem cells by reprogramming blood cells taken from patients.

Ketogenic diets can prevent or reverse heart failure caused by metabolic process

Research from Saint Louis University finds that high fat or "ketogenic" diets could completely prevent, or even reverse heart failure caused by a metabolic process.

Increased weight is causally protective for breast and prostate cancer

Although a recent campaign by Cancer Research UK emphasized obesity as a risk factor for cancer on par with smoking, the scientific literature on the relationship between increased weight and cancer risk is not so clear.

Researchers identify new potential therapeutic targets for SARS-CoV-2 infection

To identify new potential therapeutic targets for SARS-CoV-2, a team of scientists at the New York Genome Center, New York University, and the Icahn School of Medicine at Mount Sinai, performed a genome-scale, loss-of-function CRISPR screen to systematically knockout all genes in the human genome.

Study explains the nuances of mechanical signaling in cells

Actin is among the most abundant proteins in cells, and it has many jobs--from giving the cell its very shape and structure to managing networks of proteins crucial to numerous cellular functions. Without it, the fragile fundamental unit of life would crumble.

Study shows molecular link between diet and cancer risk

Scientists have detected a molecular connection between dairy and meat diets and the development of antibodies in the blood that raises the risk of cancer.

Experimental AI platform predicts best approach to cancer treatment

The U.S. Food and Drug Administration (FDA) has given final approval to only 4% of all cancer therapeutic drugs being developed.

26 Oct 2020

Study indicates underlying molecular sources in COVID-19 variability

Humans have different susceptibilities to SARS-CoV-2, and eventually develop varying degrees of fatigue, fever, and breathing problems.

Scientists design cost-effective portable analyzers

Despite their high accuracy, the majority of the existing instrumental laboratory methods are very laborious and insufficient in terms of quick analysis of the objects under study. A team of scientists of Samara Polytech design cost effective portable analyzers.

Study: Early travel restrictions have significantly limited the spread of COVID-19 virus

The coronavirus, responsible for the COVID-19 pandemic, has one official name--SARS-CoV-2. But according to virologists, mutations lead to hundreds of genetically-distinct versions of the virus.
