A new study finds that the persistence of a marker of chronic cellular stress, previously associated with neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), also takes place in the brains of Huntington's disease (HD) patients. from Top Health News -- ScienceDaily https://ift.tt/3xSmO9n via IFTTT

A groundbreaking study found that stem cells reduce the amount of virus causing AIDS, boost the body's antiviral immunity, and restore the gut's lymphoid follicles damaged by HIV. It provided a roadmap for multi-pronged HIV eradication strategies. from Top Health News -- ScienceDaily https://ift.tt/3xLGFXv via IFTTT

A new biocompatible polymer-based composite material could soon replace metal plates in treating difficult and unstable fractures. The newly-developed material is as strong as dental composites yet non-toxic. from Top Health News -- ScienceDaily https://ift.tt/3j8hEBV via IFTTT

Researchers were able to show for the first time that a very low calorie diet significantly alters the composition of the microbiota present in the human gut. The researchers report that dieting results in an increase of specific bacteria - notably Clostridioides difficile, which is associated with antibiotic-induced diarrhea and colitis. from Top Health News -- ScienceDaily https://ift.tt/2TYCtFe via IFTTT

A rare genetic defect that affects the so-called ALG2 gene can cause serious metabolic diseases in humans. Until now, its rareness and complexity made it difficult to study this congenital glycosylation disorder. A research team has finally succeeded in introducing the underlying mutation in the ALG2 gene in a fish model, allowing the causes of these complex diseases to be studied at the molecular level. from Top Health News -- ScienceDaily https://ift.tt/2UyrlPS via IFTTT

Children who were exposed to higher levels of trace minerals manganese and selenium during their mothers' pregnancy had a lower risk of high blood pressure in childhood, according to a new study. from Top Health News -- ScienceDaily https://ift.tt/3xN0vBP via IFTTT

Researchers have designed a deep learning-based system that accurately identifies individual skin stem cells grown under artificial conditions and tracks their motion. Using this system to perform quality control of stem cell cultures could improve the speed and efficiency of growing skin grafts for use in regenerative medicine and may also be useful for other types of stem cell cultures. from Top Health News -- ScienceDaily https://ift.tt/3gU275Y via IFTTT

Researchers have developed a method to combine three brain-imaging techniques to more precisely capture the timing and location of brain responses to a stimulus. Their study is the first to combine the three widely used technologies - fMRI, EEG and EROS - for simultaneous imaging of brain activity. from Top Health News -- ScienceDaily https://ift.tt/3gPz98D via IFTTT

The origins of seven types of kidney cancer, including several rare subtypes, have been identified by researchers. The findings confirm that these cancers have their origin in specific forms of developmental cells present in the maturing fetus. from Top Health News -- ScienceDaily https://ift.tt/3xQa9np via IFTTT

With the National Eye Institute reporting that about 11 million older adults in the U.S. endure a condition that leads to progressive blindness, known as age-related macular degeneration, researchers are starting to understand what goes wrong in the disease, in order to develop new therapies to treat it. from Top Health News -- ScienceDaily https://ift.tt/3gLQKya via IFTTT

A study involving virtual rather than real patients was as effective as traditional clinical trials in evaluating a medical device used to treat brain aneurysms, according to new research. The findings are proof of concept for what are called in-silico trials, where instead of recruiting people to a real-life clinical trial, researchers build digital simulations of patient groups, loosely akin to the way virtual populations are built in various computer games. from Top Health News -- ScienceDaily https://ift.tt/3gLHFW1 via IFTTT

Eating fruits with lunch, vegetables at dinner and a dairy snack in the evening was associated with a reduced risk of early death by cardiovascular disease (CVD) and all-cause mortality, according to a study of U.S. adults. Eating a Western lunch (typically containing a high quantity of refined grains, cheese and cured meat) was associated with an elevated risk of CVD and all-cause mortalities in the same study. from Top Health News -- ScienceDaily https://ift.tt/35KxBpQ via IFTTT
