Statins may protect against heart damage caused by breast cancer therapies

Statins are widely used to lower cholesterol and prevent heart disease and related deaths, but can they also help guard against heart damage caused by certain breast cancer therapies?

Switching what heart cells consume could help them regenerate

Switching what the powerhouses of heart cells consume for energy could help the heart regenerate when cells die, a new study led by UT Southwestern researchers suggests.

Fruit flies have a new defense strategy to deal with oxidative stress

Oxidative stress affects all living organisms, and the damage it causes is believed to play a part in cancer, diabetes, Alzheimer's disease and a number of other health conditions.

NUS researchers identify new protein to prevent chemotherapy-induced neuropathy

A team of researchers from the NUS Yong Loo Lin School of Medicine has identified a novel protein that would prevent the development of neuropathy in cancer patients who receive chemotherapy.

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

Free radicals from immune cells linked to salt-sensitive hypertension

In salt-sensitive hypertension, immune cells gather in the kidneys and shoot out free radicals, heightening blood pressure and damaging this pair of vital organs, scientists report.

Bats' fierce immune response to viruses could drive zoonotic emergence

It's no coincidence that some of the worst viral disease outbreaks in recent years -- SARS, MERS, Ebola, Marburg and likely the newly arrived 2019-nCoV virus -- originated in bats.

Scientists reveal the damaging effect of Zika virus on a type of brain cell

The Zika virus (ZIKV) outbreak in Brazil in 2015 sparked for many health agencies and scientists to study the pathogen, which has been linked to microcephaly and other fetal neurological disorders collectively known as Congenital Zika Syndrome.

Research unravels consequences of Zika virus attack on neural cells

Previous studies regarding the damage of the Zika virus on the brain had already pointed out the virus's predilection for a certain neural cell: the astrocyte. However, few studies have proposed to identify the infection effects on these cells, as well as their association with developmental alterations, including brain malformations and microcephaly.

A new book on antioxidant foods that prevent or treat chronic diseases

A search using medical data bases reveals that hundreds of meta-analysis papers conducted with tens of millions of people worldwide have confirmed clinically the efficacies of thirty antioxidant-rich foods to prevent or treat chronic diseases, including hypertension, diabetes, cardiovascular disease, cognitive impairment, chronic kidney disease, cancer, and more.

Exosome treatment promotes remarkable stroke recovery in swine models

It's been almost a quarter century since the first drug was approved for stroke. But what's even more striking is that only a single drug remains approved today.

Scientists use blue mushroom dye to develop fluorescent tool for detecting reactive oxygen species

A new fluorescent tool for detecting reactive oxygen species based on a chemical found in mushrooms has been developed by scientists at the University of Bath.

Research suggests contributory role of 'Asian glow' mutation and alcohol to Alzheimer’s

A new study from Stanford, published on December 12 in the journal Acta Neuropathologica Communications, suggests that an important enzyme that helps break down alcohol in the body is defective in patients with Alzheimer’s disease (AD). Understanding its relationship with alcohol and with genes that predispose to AD could help avert the latter in humans at risk.

New startup aims to prevent reperfusion-related organ damage after liver transplant

Roughly 65 years ago, the first human organ transplant was successfully performed. A decade later, heart and liver transplants became possible. Now, a startup founded by researchers from the Medical University of South Carolina and elsewhere hopes to bring about the next major breakthrough.

FDA-approved drug to prevent organ rejection may slow skin aging

The search for youthfulness typically turns to lotions, supplements, serums and diets, but there may soon be a new option joining the fray.

Researchers detect photoinitiators in human breast milk

Photoinitators (PIs) are compounds used in the ink of many types of food packaging. The substances have been shown to migrate into food and, when consumed, show up in human blood serum.

Doctors issue stern warning on e-cigarette use as it can damage vital organs

E-cigarette use has increased dramatically over the last decade. With its popularity, the use of e-cigarette spans from adolescents to adults. Now, cardiologists warn against the use of e-cigarettes and how these devices cause damage to vital organs, including the heart, brain, lungs, and blood vessels.

Study describes a molecular strategy that helps prevent development of tumors in mice

The body's process for manufacturing fatty acids is regulated by the enzyme FASN. In normal cells, this is not a very active process - except occasionally in the liver and adipose tissue - since most of the fatty acids we need for cell maintenance are obtained from the diet.

Japanese chemists develop vicinal reaction for creating highly functionalized ketones

Organic chemists are molecular architects, designing sophisticated structures. As the molecules used in science and medicine become ever more complex, new tools are needed to piece together the building blocks.
