Large-scale expansion of spike-reactive T cells feasible after COVID-19 vaccination

A new bioRxiv* preprint reports on the successful use of a protocol to expand SARS-CoV-2-reactive T-cells a thousand-fold.

Study reveals how HIV prevents the maturation of myelin-making brain cells

It's long been known that people living with HIV experience a loss of white matter in their brains. As opposed to "gray matter," which is composed of the cell bodies of neurons, white matter is made up of a fatty substance called myelin that coats neurons, offering protection and helping them transmit signals quickly and efficiently.

Gauging the efficacy and ease of use of at-home COVID-19 tests

As the country gets vaccinated and begins to re-open, testing remains a key element of safe interactions. Rapid testing for COVID-19 has become more common and accessible, including over-the-counter (OTC) tests approved by the U.S. Food and Drug Administration.

New study sheds light on why many COVID-19 patients suffer from hypoxia

A new study published in the journal Stem Cell Reports by University of Alberta researchers is shedding light on why many COVID-19 patients, even those not in hospital, are suffering from hypoxia--a potentially dangerous condition in which there is decreased oxygenation in the body's tissues.

Novel SARS-CoV-2 variants partially resistant to infection- and vaccine-induced immunity, study finds

A recent study conducted by a team of scientists in the Netherlands has revealed that while severely affected hospitalized COVID-19 patients and vaccinated individuals are capable of neutralizing the B.1.1.7, B.1.351, and P.1 variants of SARS-CoV-2, a significant proportion of non-hospitalized patients with less severe COVID-19 remain susceptible to these viral variants.

Researchers develop sophisticated data modeling to help eradicate malaria in Haiti

Researchers from Telethon Kids Institute and Curtin University in Perth and Tulane University in New Orleans have developed sophisticated data modeling that could help eradicate malaria in Haiti.

Could higher carnitine levels in the blood protect against severe COVID-19?

Researchers at the MRC Integrative Epidemiology Unit (IEU), Bristol Medical School, University of Bristol, Bristol, UK, found that carnitine and its derivative acetyl-carnitine provide a protective effect against severe COVID-19. Doubling of carnitine or acetyl-carnitine is tied to a 40-percent reduction risk of disease progression.

Could certain genes be associated with a loss of smell in some COVID-19 patients?

Researchers at the 23andMe COVID-19 Team, who help search for genetic links associated with the severity of COVID-19, found that the genes UGT2A1 and UGT2A2 may be associated with the loss of smell in those infected with SARS-CoV-2.

Could semen quality indicate SARS-CoV-2 insult susceptibility in polluted areas?

In a recent review in Environmental Science and Pollution Research, Italian researchers focused on “the evidence that correlates the degree and type of pollution with the increased susceptibility of many countries to this pandemic and proposes human semen as an early marker of the environmental health and the general health of individuals.” Their observations are based on a robust body of experimental evidence.

New vaccine candidate with RBD and N protein targets protects against SARS-CoV-2 in preclinical trials

A recent study published in the journal Science Advances, explores the immunization of RBD with the P2 epitope of tetanus toxoid, to enhance its immunogenicity, and also tests the benefit of N protein in the vaccine.

Can immunity form and interaction with seasonal coronaviruses influence SARS-CoV-2 epidemiology?

A new study hypothesizes that cross-protection from seasonal epidemics of HCoVs could not only affect SARS-CoV-2 transmission but also protect children from the disease.

Could 3D printed swabs be used to collect COVID-19 test samples?

Researchers have evaluated 3D printed sample collection swabs made in-house and found them to be a reliable alternative to commercial swabs.

A newly developed electronic ‘nose’ could identify COVID-19-infection

Developing rapid diagnostic tools is key to dealing with the COVID-19 pandemic, and a new electronic-based ‘nose’ detector could identify cases in 80 seconds.

“Cognitive clock” emerges as a new way to measure brain health

Researchers have developed a novel method to monitor the brain health of patients to improve the early diagnosis and treatment of certain diseases.

How antibody production in the lungs can determine severe respiratory infections

Recent findings describe how the presence of certain antibodies within the lungs can induce an immune response to minimize the effects of these infections.

SARS-CoV-2 can be neutralized by UV-A and UV-B

Since the end of the 1800s, Ultra-violet (UV) light has been widely documented for its germicidal properties. The UV-C light produced by low-pressure mercury tubes is widely used for disinfecting wastewater, closed environments, and biological products and is well-established, safe, and economical. UV light can have a germicidal effect on bacteria and viruses.

Positive COVID-19 screening test helps monitor respiration rate, blood-oxygen saturation at home

Two easily measurable signs of health - respiration rate and blood-oxygen saturation - are distinctly predictive of higher mortality among patients hospitalized with COVID-19, according to a study examining the cases of inpatients with COVID-19 at Rush University Medical Center and University of Washington Medicine hospitals.

Scientists test antibody-based therapy to treat Crimean-Congo hemorrhagic fever virus

Army scientists working as part of an international consortium have developed and tested an antibody-based therapy to treat Crimean-Congo hemorrhagic fever virus (CCHFV), which is carried by ticks and kills up to 60 percent of those infected.
