Antihypertensive drugs may protect against COVID-19 in heart patients

Common drugs used in high blood pressure, heart failure, and diabetic patients with kidney damage, including angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), could be protective in patients with COVID-19.

Study provides insights into pain signaling mechanism in the brain

Fast communication between our brain cells - or neurotransmission as it is called - is hugely important for our brain to work properly. Some of the messengers involved in this form of communication are neuropeptides, which are chemicals produced in the brain.

Lipid aids healing of scratches on the cornea

A species of a lipid that naturally helps skin injuries heal appears to also aid repair of common corneal injuries, even when other conditions, like diabetes, make healing difficult, scientists report.

Supercomputer helps benchmark new molecular docking tool

With the American Cancer Society estimating 1.76 million new cases and more than 600,000 deaths during 2019 in the U.S. alone, cancer remains a critical healthcare challenge.

Scientists discover tuberculosis bacterium channels vitamins into the cell

A new study published in the journal Nature in March 2020 reports a unique transport protein found within the tubercle bacillus, Mycobacterium tuberculosis. This huge membrane-spanning vesicular protein is different from other transport proteins and is instrumental in carrying hydrophilic molecules, notably vitamin B12 or cobalamin, across the cell membrane.

Study: Bacterial protein fragment instigates lung tissue death in pulmonary fibrosis

A bacterial protein fragment instigates lung tissue death in pulmonary fibrosis, a mysterious disease affecting millions of people worldwide, according to a new study from researchers at the University of Illinois at Urbana-Champaign and Mie University in Japan.

Researchers identify novel blood-based markers to detect Alzheimer’s disease

In a recent study published in the Journal of Alzheimer’s Disease, researchers at Okayama University developed a technique to uncover molecules within the blood which can help doctors differentiate patients with Alzheimer’s disease from healthy individuals.

G-FET based biosensors for selective identification of deadly bacteria strains

Using a single atom-thick sheet of graphene to track the electronic signals inherent in biological structures, a team led by Boston College researchers has developed a platform to selectively identify deadly strains of bacteria, an advance that could lead to more accurate targeting of infections with appropriate antibiotics, the team reported in the journal Biosensors and Bioelectronics.

Immune mechanism in the brain appears to play key role in the development of Alzheimer's

An immune reaction in the brain seems to play a major role in the development of Alzheimer's disease. In a way, it "adds fuel to the fire" and apparently causes an inflammation that, in a sense, keeps kindling itself. The study has now been published in the journal Cell Reports.

New, rubber-like material could act as replacement for human tissue

Researchers from Chalmers University of Technology, Sweden, have created a new, rubber-like material with a unique set of properties, which could act as a replacement for human tissue in medical procedures.

Max Planck researchers identify mechanistic basis of antigen receptor gene assembly

Adaptive immunity is a powerful defense mechanism in vertebrates. A finely tuned interplay of different cell types provides a pathogen-specific immune response to eliminate for example bacteria and viruses.

New technique helps study peptide-receptor interactions on the cell surface

In the past, biologically-active peptides - small proteins like neurotoxins and hormones that act on cell receptors to alter physiology - were purified from native sources like venoms and then panels of variants were produced in bacteria, or synthesized, to study the structural basis for receptor interaction.
