Hydroxychloroquine combined with azithromycin and abnormal heart rhythms in COVID-19 patients

A new study shows that the initially lauded combination of drugs against COVID-19 - Hydroxychloroquine and Chloroquine combined with azithromycin, could lead to abnormal and life-threatening heart rhythms. In patients hospitalized with the novel coronavirus infection or SARS CoV-2, this combination can lead to prolonged QT interval as can be detected on ECG.

Salt substitution could prevent nearly half a million cardiovascular deaths in China

A nationwide intervention to replace regular household salt with potassium-enriched salt substitutes in China could prevent nearly half a million cardiovascular deaths per year, according to a new modelling study published in the British Medical Journal.

Do ACE inhibitors increase SARS-CoV-2 binding to ACE2?

The COVID-19 pandemic has forced clinicians and academicians to intensive research to find evidence for many conventional therapies. A new round-up editorial published in the journal Cardiovascular Research in April 2020 summarizes the current clinical grounds for and against the use of the commonly used angiotensin axis inhibitors in patients with COVID-19.

Study describes unconventional mechanism of ionic channel traffic in cardiac cells

Ionic channels -integral proteins in the cell membrane- are essential in several processes such as cardiac activity, nervous transmission, cell proliferation and the regulation of blood pressure.

Screening blood samples for COVID-19 using artificial intelligence

A promising new study published in the preprint online journal medRxiv in April 2020 shows the potential of artificial intelligence (AI) for developing a patient classifier that can separate patients likely to be negative for COVID-19 from among a pool of suspected patients visiting an emergency room (ER).

New technique for imaging proteins in 3D

A team of scientists including researchers at the National Synchrotron Light Source II (NSLS-II)--a U.S. Department of Energy Office of Science User Facility at DOE's Brookhaven National Laboratory--have demonstrated a new technique for imaging proteins in 3-D with nanoscale resolution.

New computer model can screen drugs for unintended cardiac side effects

UC Davis Health researchers have developed a computer model to screen drugs for unintended cardiac side effects, especially arrhythmia risk.

Genetic mutation found to improve cognitive flexibility in mice

Researchers at the National Institutes of Health have discovered in mice what they believe is the first known genetic mutation to improve cognitive flexibility--the ability to adapt to changing situations.

Critical guidance to identify COVID-19 patients at risk of drug-induced sudden cardiac death

SARS-CoV-2, the virus that causes COVID-19, continues to spread, leading to more than 20,000 deaths worldwide in less than four months. Efforts are progressing to develop a COVID-19 vaccine, but it's still likely 12 to 18 months away.

Antibiotic blocks the integration of building blocks into the cell wall of pathogens

One of the last arrows in the quiver in the fight against dangerous bacteria is the reserve antibiotic daptomycin.

Cryo-electron microscopy helps visualize ball-and-chain inactivation of ion channels

Ion channels, which allow potassium and sodium ions to flow in and out of cells, are crucial in neuronal 'firing' in the central nervous system and for brain and heart function.

Drug from scorpion venom could offer hope for children with fetal alcohol spectrum disorder

A research team led by Children's National Hospital faculty was able to "rescue" a pre-clinical model of fetal alcohol spectrum disorder in juvenile models, reversing motor skill deficits with the help of a novel drug derived from scorpion venom.

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.

Altered potassium levels in neurons linked to mood swings in bipolar patients

People with bipolar disorder experience dramatic shifts in mood, oscillating between often debilitating periods of mania and depression.

Study reveals underlying mechanism for life-threatening cardiac arrhythmias

Low oxygen levels in the heart have long been known to produce life-threatening arrhythmias, even sudden death. Until now, it was not clear how.

Mediterranean diet promotes healthy aging with healthier gut microbiome

A new study published online in the journal Gut in February 2020 reports the striking health-promoting effects of switching to a Mediterranean diet for just one year. The results were due to an increase in the health and number of gut bacteria that favor a healthy diet.

Guideline-recommended diuretic linked to more side effects than similar antihypertensive drug

Chlorthalidone, the guideline-recommended diuretic for lowering blood pressure, causes more serious side effects than hydrochlorothiazide, a similarly effective diuretic, according to a new study led by researchers at Columbia University Irving Medical Center.

Oxidative stress induces sleep in fruit flies, research shows

Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body. Kempf

Forgiveness combined with acetaminophen can alleviate social pain

Most everyone experiences the pain of social rejection at some point in their lives. It can be triggered by the end of a romantic relationship, losing a job or being excluded by friends.
