Spending long periods in space not only leads to muscle atrophy and reductions in bone density, but it also has lasting effects on the brain. However, little is known about how different tissues of the brain react to exposure to microgravity, and it remains unclear whether and to what extent the neuroanatomical changes so far observed persist following return to normal gravity.
The study was published in the New England Journal of Medicine, they show that differential changes in the three main tissues of the brain remain detectable for at least half a year after the end of their last mission.
UT Southwestern researchers have made a major advance in uncovering the biology of how many thousands of disfiguring skin tumors occur in patients with a genetic disorder called neurofibromatosis type 1 (NF1).
This scientific advance could slow the development of these tumors. The study was published in the journal Cancer Discovery.
The emergency worker remembers when the "young and proud" Aboriginal man in his 20s was brought into the emergency department by his father. He was agitated and upset, He said he wanted to kill himself but he would not engage with us any further."
The man was seen by the psychiatry team and admitted as an involuntary patient. There were no beds available, and I was to stay in the ED until one became available. On his second day in the ED, I managed to escape.
Results from the Lipid-Rich Plaque (LRP) study demonstrate the correlation between the presence of non-flow-limiting, non-intervened upon, lipid-rich plaques detected by NIRS-IVUS imaging and the development of a major adverse cardiac event (MACE ) from a de novo culprit lesion at both the patient level (vulnerable patients) and segment level (vulnerable plaques) within 24 months post intravascular imaging.
If your mental or physical health is suffering, a lack of sleep may be to blame. Sleep is considered both restorative and restorative, and a full night's sleep is essential to our overall health and well-being. But with the frenzied pace of work, social and family demands, many people find that they are not getting the proper rest they need on a nightly basis.
New research marks an important step toward what may become a new approach to restore hearing loss. Scientists have been able to record the sensory hair cells found in the cochlea-a part of the inner ear that converts sound vibrations into electrical signals and can be permanently lost due to age or noise damage.
An estimated 30 million Americans suffer from some degree of hearing loss and people have long accepted this as a fact of life for the aging population. But animals, including birds, frogs, and fish, can regenerate lost sensory hair cells. The research appears in the European Journal of Neuroscience.
"It's funny, but mammals are the oddballs in the animal kingdom when it comes to cochlear regeneration," says study coauthor Jingyuan Zhang of the biology department at the University of Rochester. "We're the only vertebrates that can not do it."
A new study examined the relationship between fasting hyperglucagonemia-which can negatively affect glucose metabolism in patients with type 2 diabetes (T2D) -and several biochemical and glycemic factors in subjects with T2D or in a nondiabetic control group. The study results, which help to elucidate the mechanisms that underlie fasting hyperglucagonemia, are published in Metabolic Syndrome and Related Disorders.
Researchers have determined that those who identify as LGBT and have come to their family carry fewer stress hormones than those who have not come out, which may ultimately benefit their health.
The recent study by Zoccola and coauthor Andrew Manigault, MS, the study was published in the October issue of Psychosomatic Medicine, discusses how to be able to comfortably talk about your sexual identity with family members specifically, appears to be most linked to output of the stress hormone cortisol, a hormone that if too much is produced, it can damage an individual's health.
For patients with osteoporosis caused by transfusion-dependent thalassemia (TDT), a twice-yearly injection appears to improve spinal bone mineral density, according to a new study
IUPUI biologists are growing 'mini retinas' in the lab from stem cells to mimic the growth of the human retina. The researchers hope to use the research to restore sight when critical connections between the eye and the brain are damaged. These models also allow the researchers to better understand how cells in the retina develop and are organized. These results are published online in Scientific Reports
Women's bodies undergo a "striking" change during a specific week of pregnancy that can significantly reduce their risk of developing breast cancer later in life, scientists said Tuesday
Current clinical whole-body PET imaging protocols reflect the trend followed in conventional nuclear medicine in that they are optimized to produce the best image quality for qualitative visual interpretation instead of the quantitative assessment of biological parameters
