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.

Research looks at convalescent plasma use in COVID-19 mouse model

A new study by researchers at the University of Iowa and published on the preprint server bioRxiv in August 2020 reports the utility of a mouse model that recapitulates several aspects of human COVID-19 and can reflect the antiviral efficacy of new drugs as well.

SARS-CoV-2 a "swarm" of mutant viruses

In this new study, the virus was serially passaged in independent cell types in a controlled environment. The researchers found that the virus rapidly adapts to the changing conditions in culture by selecting for pre-existing species.

Can SARS-CoV-2 be transmitted via feces?

A new study by researchers at the University of Oxford and the Trip Medical Database and published on the preprint server medRxiv* in August 2020 as part of the ongoing Open Evidence Review on Transmission Dynamics of COVID-19 reports the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in feces and the need for precautions to prevent orofecal spread in the surroundings of confirmed or suspected cases.

Inhaled delivery of a potent neutralizing nanobody effective against SARS-CoV-2

A recent study by researchers from China, available on the bioRxiv preprint server, shows how stable neutralizing nanobody Nb11-59 might be a promising prophylactic and therapeutic molecule against coronavirus disease (COVID-19) – especially if administered via the inhalatory route.

First clinical trial could become an effective way to deliver chemotherapy to abdominal cancer patients

City of Hope surgical researchers are the first in the nation to open a clinical trial that could one day become an effective way to deliver chemotherapy to abdominal cancer patients who currently have very few treatment options.

SARS-CoV-2 infection and transmission possible in North American deer mice

The current COVID-19 pandemic began as a zoonosis in China, at the end of 2019, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel betacoronavirus with significant similarity to an earlier virus of the same family.

CRISPR-based COVID-19 surveillance

A recent US study available on the medRxiv preprint server supports the use of self-collected oropharyngeal swabs, together with CRISPR- and PCR-based diagnostic assays, as rapid, feasible and reliable approach for the surveillance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in university students and other asymptomatic individuals

Additional $400,000 awarded for research projects focused on cardiovascular impact of COVID-19

The American Heart Association has awarded an additional $400,000 in research grants focused on the cardiovascular impact of COVID-19.

Scientists identify new treatment targets for blinding retinal disease

When the eye isn't getting enough oxygen in the face of common conditions like premature birth or diabetes, it sets in motion a state of frenzied energy production that can ultimately result in blindness, and now scientists have identified new points where they may be able to calm the frenzy and instead enable recovery

COVID-19 patient with repeatedly undetectable SARS-CoV-2 antibodies

A recent case study published in the Journal of Applied Laboratory Medicine in August 2020 illustrates this with its finding of persistent seronegativity in a patient confirmed to be SARS-CoV-2 positive.

DHODH inhibitor PTC299 shows potential as a COVID-19 therapeutic

As COVID-19 continues to take a heavy toll on human health and life in many parts of the world, there is still no effective antiviral drug or vaccine. This has fueled an intensive search for small molecules and proteins that can inhibit viral entry and replication.

UTHSC professor recognized for contributions to pioneering cancer genomic research

Neil Hayes, MD, MS, MPH, division chief of Hematology and Oncology at the University of Tennessee Health Science Center, is among recipients of the 2020 Team Science Awards from the American Association for Cancer Research for his contributions to developing The Cancer Genome Atlas, a groundbreaking multisite project to understand cancer at its molecular level through genome sequencing and extensive data analysis.

FDA approves first oral drug for treatment of spinal muscular atrophy

The U.S. Food and Drug Administration today approved Evrysdi (risdiplam) to treat patients two months of age and older with spinal muscular atrophy (SMA), a rare and often fatal genetic disease affecting muscle strength and movement.

Scientists find new way of identifying and targeting hidden HIV viral reservoirs during ART therapy

Scientists at The Wistar Institute may have discovered a new way of identifying and targeting hidden HIV viral reservoirs during treatment with antiretroviral therapy (ART).

New approach improves SCA1 symptoms in animal models

Research has shown that a mutation in the ATAXIN-1 gene leads to accumulation of Ataxin-1 (ATXN1) protein in brain cells and is the root cause of a rare genetic neurodegenerative disease known as spinocerebellar ataxia type 1 (SCA1).

NSD2 enzyme protects against cellular senescence

Researchers from Kumamoto University in Japan have used comprehensive genetic analysis to find that the enzyme NSD2, which is known to regulate the actions of many genes, also works to block cell aging.

Coronavirus-specific structure in cells may lead to new antiviral strategies

By visualizing coronavirus replication in an infected host cell, researchers may have answered a long-standing question about how newly synthesized coronavirus components are able to be incorporated into fully infectious viruses.

Immune system derails during severe course of COVID-19

Contrary to what has been generally assumed so far, a severe course of COVID-19 does not solely result in a strong immune reaction - rather, the immune response is caught in a continuous loop of activation and inhibition.

A new method to diagnose brain tumors without any incisions

Brain tumors are typically diagnosed using MRI imaging, as taking a sample for a tissue biopsy is risky and may not be possible due to tumor location or a patient's poor health conditions.

Carefully engineered spike protein can help develop COVID-19 vaccine

The experimental vaccine against SARS-CoV-2 that was the first to enter human trials in the United States has been shown to elicit neutralizing antibodies and a helpful T-cell response with the aid of a carefully engineered spike protein that mimics the infection-spreading part of the virus.
