Researchers have found that two common approaches to post-operative atrial fibrillation -- rhythm control and rate control -- are equally safe and effective.
A study in military veterans finds that explosive blast-related concussions frequently result in hormone changes leading to problems such as sleep disturbances, fatigue, depression and poor quality of life. The research evaluated hormone levels in 41 male veterans who had been deployed to Iraq or Afghanistan.
Anabolic androgenic steroid (AAS) abuse is associated with severe blood pressure (BP) increase and hypertension, new research reports.
Brominated fire retardants, used in many consumer products and known to cause hormonal irregularities, overstimulates an adrenal gland hormone in a way that may lead to the development of cardiovascular disease, new research in human cells finds.
New research suggests pretreating cells with a peptide hormone may improve the success rate of pancreatic islet cell transplants, a procedure that holds great promise for curing Type 1 diabetes.
In obese middle-aged men, losing weight while dieting normally depletes both fat and muscle. But adding testosterone treatment may help them lose only fat and retain their muscle, new research suggests.
Aromatase inhibitors, when used for up to three years in combination with growth hormone, may effectively and safely help very short adolescent boys grow taller, new research suggests.
Young children who take antibiotics may disrupt their gut’s microbial ecosystem and be more likely to develop prediabetes in adolescence, new research reports.
A combined vaccine therapy including live Salmonella is a safe and effective way to prevent diabetes in mice and may point to future human therapies, a new study finds.
A new article provides much-needed guidance for critical care nurses and other clinicians whose patients experience continuous or recurrent seizures.
Use of nanoparticles in many applications, for instance for catalysis, relies on the surface area of the particles. Now scientists show how originally spherical nucleus can transform into cube with high surface-to-volume ratio. These nanocubes are available to be used in practice, and may interest many designers of new materials.
It could be perceived that social status can be correlated with better life chances and educational achievements for children. But is it all about the social background and income of the parents, or should children’s own cognitive abilities be taken into account? Recent research considers 4 key areas of parental social background against children’s cognitive ability to decipher their impact on educational outcomes.
Combining quantum dots and organic molecules can enable solar cells to capture more of the sun’s light, researchers report. Light from the sun is our most abundant source of renewable energy, and learning how best to harvest this radiation is key for the world's future power needs. The scientists have discovered that the efficiency of solar cells can be boosted by combining inorganic semiconductor nanocrystals with organic molecules.
Two new chambers have been discovered in the tomb of pharoah Tutankhamun. Now scientists are hoping that a second set of scans will confirm their presence unequivocally.
Critically-endangered species of fish are being sold in sushi restaurants in the UK without adequate labeling, report researchers. Overfished species of tuna and eel are among the sushi dishes being served up without adequate information to consumers, the report outlines.
Hormonally active substances may contribute to global amphibian decline. Some compounds, for example from pharmaceuticals, occur in biologically relevant concentrations in freshwater ecosystems, and thus can affect the hormonal system and the sexual development of animals. Researchers have compared the effects of the pill estrogen ethinylestradiol (EE2) in three amphibian species. The study shows that EE2 can lead to a complete feminization of genetic males. Without molecular establishment of the genetic sex, this has remained partly unnoticed.
Cystinuria occurs in one out of every 7,000 in the world, but its curative treatment has not been established. AGT1/SLC7A13, a protein, is an unknown factor that binds with the protein rBAT/SLC3A2, of which mutations may cause cystinuria leading to serious kidney failure, report researchers.
An international team of scientists was able to demonstrate in mouse and patient studies, how magnesium affects the production of blood platelets and that the TRPM7 channel function plays a key role in this process.
Terahertz is a new technology in which nondestructive testing of components and surfaces is possible. Until now, these devices and, in particular, the sensor heads have been expensive and unwieldy. Researchers have now succeeded in making sensor heads more compact and, thus, cheaper, which facilitates their handling considerably.
In computer aided vehicle engineering, you need accurate data on various environmental influences. This is the only way developers can conduct tests that simulate the experience of a real car. A quick and inexpensive new system collects real data at normal driving speeds and processes this data in real time as fine-grained and coarse-grained data for 3D driving simulations.
