One major problem with understanding Alzheimer's is not being able to clearly see why the disease starts. A super-resolution 'nanoscope' developed by Purdue University researchers now provides a 3D view of brain molecules with 10 times greater detail. This imaging technique could help reveal how the disease progresses and where new treatments could intervene.
The study also analyzed participants' overall willingness to initiate and sustain responsible drinking habits or abstinence. Compared to men, women were 38 percent more willing to initiate or try responsible drinking and 49 percent more willing to sustain those habits. Non-white college students were 41 percent more willing to initiate responsible drinking behaviors than whites and 96 percent more willing to sustain those habits.
In 'The Unmet Promise of a Miracle Drug for Alzheimer's Disease: Implications for Practice, Policy, and Research,' the authors lament the unmet promise of a miracle drug for Alzheimer disease but are heartened by what they see as encouraging improvements in care (care transformation) for a growing population of older adults, many with dementia.
White adolescent boys experiencing early puberty are at higher risk for substance use than later developing boys, a new Purdue University study finds.
Spinal muscular atrophy (SMA) is a genetic disease that affects motor neurons in the spinal cord, resulting in muscle atrophy and widespread weakness that eventually impair swallowing and breathing. A new study in the Journal of Neuromuscular Diseases finds that children with SMA type 1 can achieve improvements in motor function after six months of treatment with the drug nusinersen, particularly when treatment began before seven months of age.
Scientists have long known that RNA encodes instructions to make proteins. The building blocks that comprise RNA--A, U, C, and Gs--form a blueprint for the protein-making machinery in cells. In a new study published in Nature, scientists describe how the protein-making machinery identifies alternative initiation sites from which to start protein synthesis.
Actigraphy can be a useful clinical tool for the evaluation of adult and pediatric patients with suspected sleep disorders, including circadian rhythm sleep-wake disorders, according to a clinical practice guideline from the American Academy of Sleep Medicine (AASM).
More than a million patients are transferred between hospitals each year in the U.S. This process is challenging both for hospitals and patients and breakdowns in communication are common. A recent University of Minnesota Medical School study focuses on the patients transferring from one hospital to another and highlights the importance of efficient communication between hospitals.
Severe infections leading to hospitalizations during childhood are associated with lower school achievement in adolescence, reports a study in the July issue of The Pediatric Infectious Disease Journal (PIDJ). The official journal of The European Society for Paediatric Infectious Diseases, PIDJ is published in the Lippincott portfolio by Wolters Kluwer.
According to a new National Institutes of Health-funded study, it is not destiny that brings two fruit flies together, but an evolutionary matchmaker of sorts that made tiny adjustments to their brains' mating circuits, so they would be attracted to one another while rejecting advances from other, even closely-related, species. The results, published in Nature, may help explain how a specific female scent triggers completely different responses in different male flies.
