Exploring the potential utility of calcium channel inhibitors in SARS-CoV-2 infection

In a new study, researchers discuss the role of calcium signaling pathways as targets of inhibition in potential new antiviral therapeutic pathways for SARS-CoV-2.

Research shows a relationship between increased SARS-CoV-2 seroreactivity and antimalarial humoral immunity

Researchers investigate the cross-reactivity of the SARS-CoV-2 with pre-pandemic malaria-exposed sera samples collected from Cambodia.

SARS-CoV-2 RNA can be detected in exhaled aerosol

In a study published in the open-access journal Influenza and other Respiratory Viruses, researchers investigated if severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be detected in exhaled aerosol samples obtained from coronavirus disease 2019 (COVID-19) patients during many different types of breathing and coughing. They also analyzed how SARS-CoV-2 infection may affect the size and number of exhaled aerosol particles.

Performance of lateral flow tests for detecting SARS-CoV-2 in children falls short of minimum criteria

The performance of lateral flow (antigen) tests commonly used to detect COVID-19 infection in children falls short of the minimum criteria set by the World Health Organization (WHO) and US and UK device regulators, finds a pooled data analysis of the available evidence on 8 different tests, published in the journal BMJ Evidence-Based Medicine.

Subcutaneous nanotherapy can make immunomodulation more effective in people with type 1 diabetes

Individuals living with type 1 diabetes must carefully follow prescribed insulin regimens every day, receiving injections of the hormone via syringe, insulin pump or some other device. And without viable long-term treatments, this course of treatment is a lifelong sentence.

Study finds COVID booster maintains strong T cell response against Omicron

New study results posted to the medRxiv* preprint server found that COVID vaccine boosters increase immunity by enhancing T cell immune memory. In the face of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) Omicron variant, vaccinated people who had received a third booster shot maintained high T cell responses than people with naturally acquired immunity or vaccine-induced immunity from two doses of the SARS‑CoV‑2 vaccine.

SARS-CoV-2 protein biosensor employing colloidal quantum dots-modified electrode

An all-solid-state SARS-CoV-2 protein biosensor using lead sulfide colloidal quantum dots--modified electrode is demonstrated in this study by a group of researchers from several institutions.

Applications of bioconjugated nanomaterials in SARS-CoV-2 diagnostics

In this study, the researchers not only elucidate the recent bioconjugated nanomaterials for targeted diagnosis of SARS-CoV-2, but they also provide the rationale behind these developments by discussing the mechanisms and approaches.

Officials struggle to regulate pop-up covid testing sites — and warn patients to beware

In recent months, mobile covid-19 testing tents and vans have sprouted on urban sidewalks and street curbs as demand has skyrocketed in response to the rapid spread of the omicron variant.

New method may help make immunomodulation more effective in individuals with Type 1 diabetes

Individuals living with Type 1 diabetes must carefully follow prescribed insulin regimens every day, receiving injections of the hormone via syringe, insulin pump or some other device. And without viable long-term treatments, this course of treatment is a lifelong sentence.

Efficacy and safety of mRNA-based SARS-CoV-2 vaccination in immuno-compromised subjects

A team of researchers assessed the immune response after administering a SARS-COV-2 vaccine in immuno-compromised subjects who are potentially at an increased risk to experience severe COVID-19 and inadequate response to SARS-CoV2 vaccination.

Seroepidemiologic surveys for assessment of the COVID-19 pandemic in Japan

In a new study, a team of researchers demonstrated that Japan had witnessed a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant-induced endemic between August and December 2021.

Dexamethasone shown to upregulate innate and adaptive immune responses in COVID-19 acute respiratory distress syndrome patients

In a new study, researchers used per protocol bronchoalveolar lavage fluid (BALF) samples after intubation to evaluate the transcriptomic profiles of the local pulmonary host responses during early-stage severe coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (CARDS), non-COVID-19 ARDS, and sepsis.
