Smell and taste loss symptoms associated with robust SARS-CoV-2 antibody response in new study

Researchers in Italy report a correlation between the loss of smell and taste and an observed persistence or rise in antibody levels at five months after infection.

Traumatic or stressful events in childhood may lead to changes in key brain structures

A new study from University of Alberta researchers has shown that traumatic or stressful events in childhood may lead to tiny changes in key brain structures that can now be identified decades later.

Subgenomic RNAs could help identify asymptomatic SARS-CoV-2 infection

Researchers report the association of subgenomic RNA (sgRNA) production, the structural differences between sgRNA variants, and clinical severity in 81 clinical specimens obtained from both asymptomatic and symptomatic individuals with SARS-CoV-2 infection.

Emergence and transmission of UK SARS-CoV-2 variant in the US

Researchers describe the impending rise to dominance of the B.1.1.7 (UK) variant in the US. Understanding this development will help to shape preventive action to reduce the infection and mortality rates.

Vaccinated mothers may pass on SARS-CoV-2 antibodies to newborns

A new study describes the first case of anti-SARS-CoV-2 antibodies detected in the cord blood of an infant born to a mother immunized with the first dose of an mRNA COVID-19 vaccine three weeks earlier.

A precursor to remdesivir shows therapeutic potential for COVID-19

A new study points to the potential to use the remdesivir precursor, GS-441524, as a treatment choice for COVID-19.

Study: Human hearing process is directly linked to synchronization by gamma waves

How come we don't hear everything twice: After all, our ears sit on opposite sides of our head and most sounds do not reach both our ears at exactly the same time.

Mortality study combines drug overdose deaths with all suicide rates into a self-injury category

Classifying a death as suicide may be easiest for medical examiners and coroners in the western United States, which reports the highest suicide rates officially.

Study identifies major flaws in iBMEC-based models of the blood-brain barrier

A type of cell derived from human stem cells that has been widely used for brain research and drug development may have been leading researchers astray for years, according to a study from scientists at Weill Cornell Medicine and Columbia University Irving Medical Center.

Periodontitis treatment that changes oral bacteria also reduces severity of diabetes

We know that what happens in the mouth doesn't stay in the mouth - but the oral cavity's connection to the rest of the body goes way beyond chewing, swallowing and digestion.

Immune responses to insulin could help identify individuals at risk for developing type 1 diabetes

Researchers from the Barbara Davis Center for Childhood Diabetes at the University of Colorado Anschutz Medical Campus have found that immune responses to insulin could help identify individuals most at risk for developing Type 1 diabetes.

Simple blood test can detect a wide range of diseases

In diagnostic medicine, biopsies, where a sample of tissue is extracted for analysis, is a common tool for the detection of many conditions. But this approach has several drawbacks - it can be painful, doesn't always extract the diseased tissue, and can only be used in a sufficiently advanced disease stage, making it, in some cases, too late for intervention.

Pancreatic β cells secrete miR-29 in response to high levels of free fatty acids

In a new study published in Journal of Extracellular Vesicles, Chen-Yu Zhang's group and Antonio Vidal-Puig's group at University of Cambridge report that pancreatic β cells secrete miR-29 family members (miR-29a, miR-29b and miR-29c) in response to high levels of free fatty acids (FFAs). These β cell-derived miR-29s are delivered to the liver, promoting insulin resistance and enhancing hepatic glucose output.

Human-caused climate change plays key role in allergy outcomes

If you live with seasonal allergies and feel like the pollen seasons feel longer and longer every year, you may be right. New research shows that pollen seasons start 20 days earlier, are 10 days longer, and feature 21% more pollen than in 1990 - meaning more days of itchy, sneezy, drippy misery.

Researchers look at long-term outcomes of cancer patients diagnosed with COVID-19

Researchers at MUSC Hollings Cancer Center have joined a nationwide study to look at the long-term outcomes of cancer patients who have been diagnosed with COVID-19.

Differences in gene readouts may shed light on mental disorders

A new study suggests that differences in the expression of gene transcripts - readouts copied from DNA that help maintain and build our cells - may hold the key to understanding how mental disorders with shared genetic risk factors result in different patterns of onset, symptoms, course of illness, and treatment responses

New U.K. SARS-CoV-2 variant may cause more severe illness, study finds

Researchers at the London School of Hygiene and Tropical Medicine revealed that the VOC 202012/01 variant is not only fast-spreading and easily transmissible but also may cause more severe illness.

One-dose SARS-CoV-2 vaccine policy may lead to antigenic evolution, study finds

In a new study, published on the pre-print server medRxiv, an international team of researchers found that a one-dose policy may increase the potential for antigenic evolution. The study revealed that focusing on one dose may decrease infections in the short term, but longer-term outcomes rely on this immune strength.

HIV: New therapeutic approach to restore the effectiveness of immune cells

Prompted by the need to improve conventional treatments for people infected with the human immunodeficiency virus (HIV-1), a team from the Institut national de la recherche scientifique has identified a therapeutic approach to restore the effectiveness of immune cells.

Compound isolated from Ophiura sarsii can be used as an affordable drug for photodynamic therapy

An unusual biologically active porphyrin compound was isolated from seabed dweller Ophiura sarsii. The substance might be used as an affordable light-sensitive drug for innovative photodynamic therapy and for targeted treatment of triple-negative breast cancer and some other cancers.
