Less than half of women who filled a statin prescription following a heart attack received a high-intensity statin--indicating they continue to be less likely than men to be prescribed this lifesaving treatment, according to a study published today in the Journal of the American College of Cardiology. The persistent gap in heart disease treatment between women and men continues despite similar effectiveness of more-intensive statins for both sexes and recent efforts to reduce sex difference in guideline-recommended treatment.
Health checks including diabetes risk assessment have been introduced in a number of countries. However, there are few population-based trials assessing the benefits, harms and costs of these screening programmes, and these have shown mixed results.
SOLOMON ISLANDS (April 16, 2018) - Globally, remaining tropical forests are being rapidly cleared, particularly in countries like the Solomon Islands where commercial logging accounts for about 18 percent of government revenue, and at least 60 percent of exports while providing the largest number of formal sector jobs. However, the loss of native forests has huge ecological and social consequences, many of which are poorly documented.
Researchers at the National Institute of Standards and Technology (NIST) continue to pioneer new antenna measurement methods, this time for future 5G wireless communications systems.
Scientists at the University of Waterloo have developed a new tool to protect women from HIV infection.
The tool, a vaginal implant, decreases the number of cells that the HIV virus can target in a woman's genital tract. Unlike conventional methods of HIV prevention, such as condoms or anti-HIV drugs, the implant takes advantage of some people's natural immunity to the virus.
DARIEN, IL - April 16, 2018 - Medical cannabis and synthetic marijuana extracts should not be used for the treatment of obstructive sleep apnea, according to a position statement from the American Academy of Sleep Medicine (AASM).
DARIEN, IL - April 16, 2018 - A position statement from the American Academy of Sleep Medicine (AASM) concludes that fatigue and sleepiness are inherent safety risks in the ridesharing industry.
A team from the Spanish National Cancer Research Centre (CNIO) has determined for the first time the high-resolution structure of a complex (R2TP) involved in key processes for cell survival and in diseases such as cancer. This achievement has been made possible by using high-resolution cryo-electron microscopy, a technique brought to the CNIO thanks to Óscar Llorca, director of the Structural Biology Programme and lead author on the paper published in Nature Communications.
CAMBRIDGE, MA -- During the past several years, many strains of bacteria have become resistant to existing antibiotics, and very few new drugs have been added to the antibiotic arsenal.
To help combat this growing public health problem, some scientists are exploring antimicrobial peptides -- naturally occurring peptides found in most organisms. Most of these are not powerful enough to fight off infections in humans, so researchers are trying to come up with new, more potent versions.
New research published in The Journal of Physiology has indicated why people with paralysis of their limbs and torso are more likely to suffer from sleep apnoea. This knowledge could be used to develop much-need targeted therapies.
The hippocampus is an area of the brain commonly linked with memory and dementia.
But new U of T Scarborough research finds that it may also yield important clues about a range of mental health illnesses including addiction, anxiety and depression.
The research, authored by a team of neuroscientists, found that a specific part of the hippocampus could play an important role in emotional regulation, a finding that calls into question our understanding of how exactly this part of the brain works.
14 April 2018, Paris, France: A single treatment using an optimized, targeted form of faecal microbiota transplantation (FMT) produces sustained clinical and cognitive improvements, according to the results of a long-term follow-up of patients with liver cirrhosis and hepatic encephalopathy (HE) who had participated in a short-term study.
RIVERSIDE, Calif. -- A team of researchers at the University of California, Riverside have isolated three previously unknown bacterial species from wild bees and flowers. The bacteria, which belong to the genus Lactobacillus, may play a role in preserving the nectar and pollen that female bees store in their nests as food for their larvae.
Losing just one night of sleep led to an immediate increase in beta-amyloid, a protein in the brain associated with Alzheimer's disease, according to a small, new study by researchers at the National Institutes of Health. In Alzheimer's disease, beta-amyloid proteins clump together to form amyloid plaques, a hallmark of the disease.
The researchers within the groups of Prof Dr Lars Schäfer and Prof Dr Enrica Bordignon, who work together in the Excellence Cluster Ruhr explores Solvation, Resolv in short, report in the Journal of the American Chemical Society of 16 March 2018.
"ABC transporters are fascinating biological nanomachines", says Lars Schäfer, head of the Molecular Simulation research group. These proteins couple the binding and chemical cleavage of ATP molecules, the chemical energy unit of the cell, with the transport of molecules through biological membranes.
