Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

Zinc inhibits SARS-CoV-2’s main protease in vitro

Zinc has antiviral properties. However, the detailed kinetics and the mechanism of zinc in the inhibition of viruses, particularly SARS-CoV-2 – the causative virus of COVID-19 – is unclear. To probe the role of zinc as an anti-SARS-CoV-2 agent at the structural and molecular level, researchers in India studied the binding kinetics and the inhibition mechanism of zinc with SARS-CoV-2’s viral proteins.

A new strategy to combat pathogenic bacterium

Pseudomonas aeruginosa is an opportunistic pathogenic bacterium present in many ecological niches, such as plant roots, stagnant water or even the pipes of our homes. Naturally very versatile, it can cause acute and chronic infections that are potentially fatal for people with weakened immune systems.

Yeast cell machinery seamlessly 'reads' the unnatural ingredients in the genetic recipe

If the genome is the recipe of life, base pairs are the individual ingredients listed. These chemical structures form DNA, and every living organism on Earth has just four. The specific arrangements of these four base pairs -- A, T, C, G -- make us who and what we are.

RIG-1 agonist shows potent antiviral efficacy against SARS-CoV-2 infection

A team of scientists from the United States has recently revealed the antiviral efficacy of stem-loop RNA 14, a RIG-1 agonist, in controlling severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in mice. The compound reduces the risk of severe coronavirus disease 2019 (COVID-19) by inhibiting viral replication in the lower respiratory tract. The study is currently available on the bioRxiv* preprint server.

Scientists develop low-cost lab-on-paper device for rapid and accurate detection of SARS-CoV-2

A team of scientists from the University of Connecticut, USA, has developed a low-cost lab-on-paper technology to rapidly and easily detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The work has recently been published in a Royal Society of Chemistry’s Lab on a Chip journal.

Combination of interferon-α and nafamostat inhibits SARS-CoV-2 in vivo

A new study, released as a preprint on bioRxiv* server, shows that a combination of the biological interferon-α and the small molecule nafamostat are effective against SARS-CoV-2 infection in vitro, as well as in vivo.

Study examines SARS-CoV-2 replication in cells using super-resolution microscopy

Despite tremendous efforts by the global scientific community to curb the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by developing more efficient testing protocols, therapies, and vaccines at a rapid pace, relatively little is known about the dynamics of SARS-CoV-2 replication within cells.

Study shows how epigenetic factors modulate the risk of type 1 diabetes

Genetics plays a major role in determining a person’s risk of developing type 1 diabetes, but environmental and lifestyle factors are also important. In an article recently published in Chinese Medical Journal, a team of researchers explore the interplay of genetic and environmental factors by summarizing the literature on type 1 diabetes and epigenetics—the study of how gene expression patterns can be modified.

Which vitamins and minerals help with COVID?

A study published in the journal Inflammopharmacology reviewed recent data related to the role of vitamins and minerals in treating COVID-19 patients. The primary goal of the review is to highlight the possible therapeutic role of vitamins A, B, C, D, E and K, and micronutrients as immunity boosters in COVID-19 patients.

The SARS-CoV-2 virus and its vaccines pose unique challenges

Iranian researchers recently provided a review of the attempts made to develop safe SARS-CoV-2 vaccines. The researchers outlined potential challenges and concerns, including disease enhancement, virus mutation, and public acceptability. Their work is published in the journal Immunological Investigations.

Study: Cancer cells grown in culture dishes have less parity with their human sources

In a bid to find or refine laboratory research models for cancer that better compare with what happens in living people, Johns Hopkins Medicine scientists report they have developed a new computer-based technique showing that human cancer cells grown in culture dishes are the least genetically similar to their human sources.

Genetically engineering NK cells can destroy tumor-regenerating glioblastoma stem cells

Preclinical research from The University of Texas MD Anderson Cancer Center finds that although glioblastoma stem cells (GSCs) can be targeted by natural killer (NK) cells, they are able to evade immune attack by releasing the TFG-β signaling protein, which blocks NK cell activity.
