Doing less exercise could deactivate a vital protein in the body, suggests study

Doing less exercise could deactivate a vital protein in the body, causing further inactivity and making exercise more difficult, new research suggests.

Researchers create a comprehensive atlas of cerebrovascular cell types

While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that deliver oxygen and other nutrients to the brain.

Combined strategy suppresses the growth of deadly brain tumor

Short bursts of radiation therapy dramatically enhanced the efficiency of targeting glioblastomas with natural nanoparticle-based immunotherapy, thus suppressing growth of the deadly tumor, inducing anti-tumor immunity and prolonging survival in animal models, a research team at Massachusetts General Hospital has discovered.

Exploring loss of Y chromosome in white blood cells as a risk-factor of life-threatening COVID-19 in men

Researchers published a study exploring the possibilities of predisposing men for a life-threatening disease course of COVID-19.

Study uncovers a harmful neutrophil behavior linked to cardiovascular disease

Scientists led by Dr. Andrés Hidalgo at the Centro Nacional de Investigadores Cardiovasculares have discovered that circulating neutrophils-;a type of immune cell-;acquire different behavior patterns during inflammatory processes.

X-ray imaging of cardiac tissue reveals the impact of Covid-19 on the heart

An interdisciplinary research team from the University of Göttingen and Hannover Medical School (MHH) has detected significant changes in the heart muscle tissue of people who died from Covid-19.

Researchers find muscle growth in some critically ill COVID-19 patients

Muscles appear to grow, rather than shrink, in some critically ill COVID-19 patients, finds new research being presented at Euroanaesthesia, the annual meeting of the European Society of Anaesthesiology and Intensive Care, held online this year.

Gene key to excessive cell proliferation could be a potential target for fatal pulmonary hypertension

A gene that is overexpressed in some aggressive cancers also appears to be key to the excessive cell proliferation that thickens the walls of pulmonary arteries and ultimately causes the right ventricle of the heart to fail, scientists report.

Study measures arterial stiffness in women from wide age range

A study conducted at the University of Jyväskylä in the Faculty of Sport and Health Sciences measured arterial stiffness in women from wide age range.

Using soft X-ray tomography for 3D imaging of cell structures in few minutes

Viral pathogens like the SARS-CoV-2 coronavirus change the interior structure of the cells they infect. These changes occur at the level of individual cell components – the organelles – and can provide information on how viral diseases develop.

Therapeutic heparin for preventing COVID-19 deaths is four times higher than the prophylactic dose

The anti-coagulant heparin reduces the likelihood of death from COVID-19 by 78% when administered in therapeutic doses to patients with signs of respiratory failure on admission to hospital, according to a study reported on October 14 in the British Medical Journal.

Researchers identify a common gene variant that drives the efficiency and outcome of dialysis

Every day, the human kidneys clean about 1,500 liters of blood by producing approximately 1–2 liters of urine. Thereby, the body gets rid of excess water and toxic waste products of the metabolism or also drugs and maintains the balance of water and minerals in the tissues.

Research reveals new role of immune cells that protect the brain from disease and injury

University of Virginia School of Medicine researchers have revealed a vital but previously unknown role for immune cells that protect the brain from disease and injury: The cells, known as microglia, also help regulate blood flow and maintain the brain's critical blood vessels.

Scientists move a step closer to harnessing viruses to fight antibiotic resistance

As antibiotics increasingly develop resistance to bacteria that cause infection, scientists have moved a step closer to harnessing viruses as an alternative form of therapy.

Dynamics of innate immune responses decide COVID-19 severity in genetically diverse mice

In a recently published article on the bioRxiv* preprint server, scientists from the USA and UK have described the significance of early inflammatory signaling pathways in determining the severity of coronavirus disease 2019 (COVID-19).

Liver may play a key role in the onset or progression of Alzheimer's disease

Amyloid protein made in the liver can cause neurodegeneration in the brain, according to a new study in the open-access journal PLOS Biology, by John Mamo of Curtin University in Bentley, Australia, and colleagues.

Home blood collection device could be used for measuring antibodies against SARS-CoV-2

A device that could make it possible for patients to draw their own blood at home was successfully used to collect blood samples for measuring antibodies against SARS-CoV-2, the virus that causes COVID-19, researchers at the University of Washington School of Medicine in Seattle report.

The influence of COVID-19 on platelet activation and aggregation

In a paper recently uploaded to the bioRxiv* preprint server, humanized ACE2 mice are infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and platelets are subsequently isolated from the blood for quantitative proteomic analysis.
