ACE2/TMPRSS2 not expressed in pancreatic islet endocrine cells

A new study by researchers at the Vanderbilt University Medical Center and the University of Pennsylvania Perelman School of Medicine and published on the preprint server bioRxiv* in August 2020 reports that both key enzymes that are required for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) entry into the human host cell are lacking in the beta cells of the pancreatic islet. This rules out the direct injury hypothesis for impaired glucose control in patients with COVID-19 disease.

Researchers develop 3D imaging technique to visualize damaged lung tissue after severe COVID-19

Physicists at the University of Göttingen, together with pathologists and lung specialists at the Medical University of Hannover, have developed a three-dimensional imaging technique that enables high resolution and three-dimensional representation of damaged lung tissue following severe Covid-19.

COVID-19 causes significant dilation of lung blood vessels, indicates study

A new pilot study from the Icahn School of Medicine at Mount Sinai suggests that COVID-19 is causing significant dilation of the blood vessels of the lung, specifically the capillaries.

Bioinformatics identifies key genes and cellular pathways in COVID-19

The COVID-19 pandemic is showing no signs of waning or extinction anytime soon. Now, a new study published on the preprint server bioRxiv* in August 2020 shows a new bioinformatics approach to studying the pathogenesis of this disease, by uncovering the differentially expressed genes (DEGs) and cell signaling pathways that cause the disease characteristics. This will help develop better therapies to counter the effects of these genes.

ARDS may not be the primary lung iInjury in COVID-19

A new Italian study published on the preprint server medRxiv in August 2020 shows that this may not be an adequate explanation, since ARDS is a nonspecific diagnosis. Instead, they say, antemortem lung biopsy shows a “Covid pattern” of acute lung injury, which could guide the application of therapeutics.

Scientists identify new treatment targets for blinding retinal disease

When the eye isn't getting enough oxygen in the face of common conditions like premature birth or diabetes, it sets in motion a state of frenzied energy production that can ultimately result in blindness, and now scientists have identified new points where they may be able to calm the frenzy and instead enable recovery

Researchers launch randomized, placebo-controlled clinical trial of pulmozyme in COVID-19 patients

Researchers at Boston Children's Hospital and Brigham and Women's Hospital have launched a randomized, placebo-controlled clinical trial of dornase alfa (Pulmozyme) in patients with severe COVID-19 pneumonia and respiratory failure requiring mechanical ventilation.

Study identifies mechanisms that underlie olfactory symptoms of COVID-19

A new study of human olfactory cells has revealed that viral invasion of supportive cells in the nasal cavity might be driving the loss of smell seen in some patients with COVID-19.

Autopsies reveal unexpected changes in the hearts of COVID-19 patients

A series of autopsies conducted by LSU Health New Orleans pathologists shows the damage to the hearts of COVID-19 patients is not the expected typical inflammation of the heart muscle associated with myocarditis, but rather a unique pattern of cell death in scattered individual heart muscle cells.

COVID-19 complications may be associated with von Willebrand factor in the blood

Anna Aksenova, a senior research associate at the Laboratory of Amyloid Biology at St Petersburg University, has advanced a hypothesis that the severe course of COVID-19 may be associated with von Willebrand factor.

Latest findings put Benson Viscometers at the forefront of Covid-19 fight

A clinical viscosity diagnostic instrument is proving to be valuable in the research and treatment of coronavirus after laboratory scientists have identified its ability to provide meaningful data for medical teams treating Covid-19 patients.

Blood cell damage in COVID-19 may compromise oxygen transport

Researchers in the U.S. have shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may alter key protein structures on red blood cells and compromise the transport and delivery of oxygen in patients with coronavirus disease 2019 (COVID-19).

Artificial red blood cells mimic the favorable properties of natural ones

Scientists have tried to develop synthetic red blood cells that mimic the favorable properties of natural ones, such as flexibility, oxygen transport and long circulation times.

UZH researchers develop new X-ray contrast agent for high-resolution vascular imaging

Various diseases in humans and animals - such as tumors, strokes or chronic kidney disease - damage the blood vessels. Capillaries, the smallest blood vessels in the body, are particularly affected.

Inexpensive screening method for retinal changes in diabetics

Retinal damage due to diabetes is now considered the most common cause of blindness in working-age adults.

Capillary leakage important in COVID-19 respiratory distress

Now, a new study published on the preprint server medRxiv reports the pivotal role played by protein leakage through lung capillaries and promotes the use of serum albumin as a biomarker of disease progression and severity.

Tocilizumab improves survival in COVID-19 patients with ARDS

The current COVID-19 pandemic caused by the SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2), has already nearly 4.8 million confirmed cases and more than 318,000 deaths.

Clinical trial to test the efficacy of defibrotide medicine for reducing COVID-19 death rate

The Neurosciences Institute, mixed centre of the Spanish National Research Council and the Miguel Hernández University of Elche, have collaborated on the first clinical trial conducted in the world to test whether the defibrotide medicine, which has already been authorized to treat a severe obstruction of the hepatic sinusoidal veins of people who have undergone a bone marrow transplant, can be used as therapy against COVID-19.

Study: Chronic exposure to inhaled nicotine alone leads to pulmonary hypertension

A study conducted by a team of researchers at LSU Health New Orleans has shown for the first time that chronic exposure to inhaled nicotine alone increases blood pressure (hypertension), in both the body's general circulation and in the lungs that can lead to pulmonary hypertension.
