Alkaloids show potential as treatments for COVID-19

To further study these organic compounds, researchers from Kermanshah University of Medical Sciences, Iran, and Universidad de Santiago de Chile, Chile, reviewed the role of alkaloids as a potential antiviral, specifically against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They presented the chemistry, plant sources, and antiviral effects of alkaloids and their anti-SARS-CoV-2 effect.

Treatment-resistant depression relieved by laughing gas

Researchers at the Washington University School of Medicine in St. Louis and the University of Chicago have found that a single, one-hour treatment involving the inhalation of a mixture of oxygen and the anesthetic drug nitrous oxide, also known as laughing gas, can improve symptoms of depression in people resistant to treatment.

CDC reports rare cases of heart inflammation in young men after mRNA COVID-19 vaccination

Vaccination efforts have rolled out in most countries starting in the last quarter of 2020 with more than 2.37 billion vaccines administered worldwide so far. However, reports of cardiac inflammation (myocarditis and pericarditis) occurring after the mRNA COVID-19 vaccination (Pfizer-BioNTech and Moderna) have increased in the United States since April 2021.

Analysis of COVID-19 patients with repeatedly positive SARS-CoV-2 tests

New research published on the medRxiv preprint server provides a detailed analysis of COVID-19 patients who had repeated positive PCR tests for SARS-CoV-2 infection in a large US COVID-19 electronic health record (EHR) database.

Rural Missouri counties experience nursing shortages at a greater rate, shows study

While the United States faces a nationwide nursing shortage, a recent study at the University of Missouri found rural Missouri counties experience nursing shortages at a greater rate than the state's metropolitan counties.

REGEN-COV antibody cocktail shown to significantly lower SARS-CoV-2 viral load

In human trials, the interim analysis of 275 participants showed REGEN-COV quickly reduced viral loads. Moreover, this reduction was much faster in people who did not have a high viral load when they started treatment.

Immune memory responses differ between SARS-CoV-2 and influenza A

Researchers in Canada have shown that the long-lasting immunity that develops following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is characterized by different T cell responses than those observed for influenza A virus-specific immune memory.

SARS-CoV-2 variant of concern could cause further epidemics in UK

The team – from the University of Warwick, the University of Manchester, and the University of Oxford – say that a variant of concern that has either a substantial transmission advantage over resident lineages, or the ability to evade vaccine- or infection-induced immunity, can be expected to drive a wave of infections and hospitalizations similar to that seen in the country during the winter of 2020-21.

Plasma zinc status not an effective prognostic factor for hospitalized COVID-19 patients

Due to previous evidence suggesting that zinc deficiencies can lead to complications along with an impaired antiviral response, a group of international researchers has undertaken a prospective observational study to investigate this association further.

Study uncovers novel drug that effectively thwarts pancreatic tumors

Pancreatic cancer is an aggressive disease in which malignant cells form in the tissues of the pancreas, a long and flat gland located behind the stomach that helps with digestion and blood sugar regulation.

South African and Brazilian SARS-CoV-2 variants overtake UK variant in French regions

Researchers have found that the variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that were initially identified in South Africa (B.1.351) and Brazil (P.1) appear to be spreading more quickly in some areas of France than the previously dominant UK variant B.1.1.7.

Study reveals risk factors associated with COVID-19 outcomes for people with IDD

A study of nearly 550 adults with intellectual and developmental disabilities receiving residential services in New York City found that age, larger residential settings, Down syndrome and chronic kidney disease were the most common risk factors for COVID-19 diagnosis, and heart disease was most associated with COVID-19 deaths.

Stents inspired by kirigami could deliver drugs to tubular organs

Inspired by kirigami, the Japanese art of folding and cutting paper to create three-dimensional structures, MIT engineers and their collaborators have designed a new type of stent that could be used to deliver drugs to the gastrointestinal tract, respiratory tract, or other tubular organs in the body.

Researchers develop new imaging technique for studying nanoscale coronavirus-host interactions

Lei S. Qi of Stanford University, California, and colleagues published research showing a potential framework to better characterize coronaviruses' biology. While most high-resolution imaging techniques show the life cycle of coronaviruses, identifying viral or host proteins and genomes remains poorly understood. Their results use multi-color super-resolution imaging allows them to study nanoscopic parts of the coronavirus, including RNA.
