Neutrolis announces development of first-in-class therapy to target NETs in COVID-19 patients

Neutrolis, a biotechnology company developing therapeutics that target neutrophils, the most abundant immune cells in the body, today announced the development of NTR-441, a first-in-class DNASE1L3 enzyme analog that has the potential to rapidly and systemically clear neutrophil extracellular traps for severe cases of COVID-19.

Despite COVID-19 pressures, hospitals are maintaining emergency cardiac services in majority of cases

The death rate for patients who experienced what is normally a lower-risk heart attack rose sharply during the peak of the COVID-19 pandemic in England, according to an analysis of NHS data.

Targeting LDL cholesterol to reduce heart disease risk now questioned

For many years, health experts have warned that high levels of bad cholesterol or low-density lipoprotein (LDL) are critical drivers for the development of cardiovascular disease. Now, a new study claims that decades of research have failed to show benefit of targeting the bad cholesterol to reduce the risk of cardiovascular disease.

How COVID-19 lockdown affected the heart

A new study published on the preprint server medRxiv in August 2020 shows that heart rate variability assessments, used to evaluate the health of the heart and blood vessels, are useful in identifying changes in health and well being throughout lockdown related to COVID-19.

Study uncovers how schistosome worms trick the host's immune system

Researchers uncovered in a new study how schistosomes, parasitic flatworms that infect more than 200 million people in the tropics, trick the host's immune system and continue producing eggs for decades.

New method to detect rare circulating tumor cells in blood samples

Metastasis - the development of tumor growth at a secondary site - is responsible for the majority of cancer-related deaths. It occurs when the primary tumor site sheds cancerous cells which are then circulated through the body via blood vessels or lymph nodes.

Portable, injectable clotting agent reduces blood loss by 97% in mice models

When it comes to traumatic injuries, it's a race against time. A person with major hemorrhage can die from blood loss within minutes, so staunching the wound and getting them to a hospital as fast as possible is critical.

Investigational drug shows promising results for treating HNSCC tumors

Head and neck cancer is one of the leading causes of cancer-related deaths worldwide, and squamous cell carcinomas (HNSCC) account for the majority of these cases.

First case report on pathologic findings of vasculitis of the small vessels in the heart

A team of LSU Health New Orleans pathologists published what is believed to be the first case report on pathologic findings of vasculitis of the small vessels of the heart, which likely represents multisystem inflammatory syndrome.

Pilot study shows cholesterol-lowering medication improves function of coronary arteries

In a pilot study of people living with HIV or high levels of cholesterol, Johns Hopkins Medicine researchers found that a six-week course of a cholesterol-lowering medication improved the function of the coronary arteries that provide oxygen to the heart.

Remnants of bird ovaries can be preserved in the fossil record, confirms study

A research team led by Dr. Alida Bailleul from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences has put one controversy to rest: whether or not remnants of bird ovaries can be preserved in the fossil record.

Platelet hyperreactivity, a unique feature of COVID-19

A new study by Irish researchers and published in the preprint server medRxiv in July 2020 reports a bidirectional relationship between COVID-19 and coagulation abnormalities.

Computational analyses suggest new pathway for inflammatory response to SARS-CoV-2

Analyses of lung fluid cells from COVID-19 patients conducted on the nation's fastest supercomputer point to gene expression patterns that may explain the runaway symptoms produced by the body's response to SARS-CoV-2.

28 Jul 2020

Varying immune system responses can predict severe COVID-19 outcomes

The differing immune system responses of patients with COVID-19 can help predict who will experience moderate and severe consequences of disease, according to a new study by Yale researchers published July 27 in the journal Nature.

Little-used measurement of 'good cholesterol' can better predict heart attack and stroke risk

For decades, high-density lipoprotein (HDL) cholesterol has been dubbed "good cholesterol" because of its role in moving fats and other cholesterol molecules out of artery walls.

High ACE2 Expression on pancreatic islet cells during inflammation could explain new-onset diabetes in COVID-19

A new study suggests that the SARS-CoV-2 infection may be linked to the onset of diabetes, via the infection of pancreatic islet beta cells, which produce insulin.

Researcher receives Outstanding Investigator Award for groundbreaking microvascular and circulation research

Sarah Yuan, MD, PhD, professor and chair of the Department of Molecular Pharmacology and Physiology at the USF Health Morsani College of Medicine, has received a highly competitive National Heart, Lung, and Blood Institute (NHLBI) Outstanding Investigator Award to continue breaking new ground in microvascular and circulation research.

Neurotransmitter-derived lipidoids help carry drugs across the blood-brain barrier in mice

Biomedical engineers at the Tufts University School of Engineering have developed tiny lipid-based nanoparticles that incorporate neurotranmitters to help carry drugs, large molecules, and even gene editing proteins across the blood-brain barrier and into the brain in mice.

SphingoTec launches point-of-care test for bio-ADM, a biomarker for life threatening endothelial dysfunction

Diagnostics company SphingoTec GmbH today announced the launch of its IB10 sphingotest® bio-ADM®, a CE-IVD-marked point-of-care test to quantitatively determine blood levels of Bioactive Adrenomedullin. Blood levels of bio-ADM® reflect in real-time the functional status of the endothelium, the inner cell sheet of blood vessels.
