A team of scientists, with the first author from the HSE University, were investigating which factors are the most important for the upper limb motor recovery after a stroke. The study is published in Stroke.

Neurons control blood flow in tiny vessels in the brain, but researchers know little about this relationship. Now a team of Penn State engineers has found a connection between nitric oxide expressing neurons and changes in arterial diameters in mice, which may shed light on brain function and aging.
As humans evolve, cancer also evolves in parallel, making the race for finding efficient treatment methods for cancer patients challenging and constant. In addition to designing drugs for treatment, the delivery of these drugs to targeted organs is also a major challenge faced by the cancer research community.
With nearly 2 million Americans battling type 1 diabetes, it is no surprise that clinical therapies for the disease are constantly evolving and improving. In type 1 diabetes mellitus, the body's immune system attacks and destroys insulin-producing β-cells. As a result, people living with type 1 diabetes lose insulin secretion and encounter difficulty regulating glucose levels -- especially after meals. Drugs developed to proliferate β-cells often are inefficient and have off-target effects that can dysregulate other cell types and pancreatic hormone production.
DARIEN, IL - The American Academy of Sleep Medicine has published a new clinical practice guideline establishing recommendations for the use of behavioral and psychological treatments for chronic insomnia disorder in adults.
BIRMINGHAM, Ala. - The bacteria Streptococcus pneumoniae colonizes the nasopharynx and can cause pneumonia. Then, it can spread from the lungs to the bloodstream and cause organ damage. This opportunistic pathogen commonly infects young children, those who are immunocompromised and the elderly. In 2015, S. pneumoniae infections worldwide killed an estimated 192,000 to 366,000 children under age 5.
Research has shown that human milk is the optimal nutrition source for neonates and infants. It confers protection against both immediately life-threatening infant diseases such as necrotizing enterocolitis, as well as later onset diseases in adults, like obesity, diabetes and inflammatory bowel disease. Scientific evidence suggests that what a mother eats while she is breastfeeding can modulate the beneficial composition of the mother's milk, but the underlying mechanisms involved have not been elucidated.
A group of proteins called 4E-BPs, involved in memory formation, is the key to unlocking the antidepressant effect of ketamine in the brain, according to researchers from three Canadian universities. The discovery could lead to better and safer treatments for certain patients suffering from major depression.
Because more than 30% of patients are resistant to selective serotonin reuptake inhibitors (SSRI), the most commonly-prescribed antidepressants, finding an effective treatment for major depressive disorder is challenging.
LA JOLLA--(December 16, 2020) Getting computers to "think" like humans is the holy grail of artificial intelligence, but human brains turn out to be tough acts to follow. The human brain is a master of applying previously learned knowledge to new situations and constantly refining what's been learned. This ability to be adaptive has been hard to replicate in machines.
PHOENIX, Ariz. -- Dec. 15, 2020 -- The Translational Genomics Research Institute (TGen), an affiliate of City of Hope, has identified a specific genetic target that could help explain the tremendous variation in how sick those infected with COVID-19 become.
COLUMBUS, Ohio -- A new study offers strong evidence that kids who use e-cigarettes are more likely to take up smoking or smokeless tobacco, researchers say.
Teen boys who vaped were almost three times as likely to start smoking as other teen boys with similar risk profiles and more than two times as likely to try smokeless tobacco, the study from The Ohio State University found. The research was published online this week in the journal Addictive Behaviors.
BOSTON - (December 16, 2020) - Intensive interventions to reduce blood glucose and blood pressure levels in type 2 diabetes reduce the risk of developing cardiovascular autonomic neuropathy (CAN), a frequent but underdiagnosed complication of diabetes that can be life-threatening.
Natural variations in ultraviolet radiation influence the spread of COVID-19, but the influence is modest compared to preventive measures such as physical distancing, mask wearing, and quarantine, according to new research from Harvard University.
Groundbreaking research led by a team of scientists including a University of Massachusetts Amherst biostatistician shows that oral hormone therapy (HT) significantly alters the metabolome of postmenopausal women. This finding, which examined blood specimens from the landmark Women's Health Initiative (WHI) study, may help explain the disease risks and protective effects associated with different regimens of hormone therapy.
CAMBRIDGE, MA--December 16, 2020--In 2019, the National Academies of Science, Engineering, and Medicine (NASEM) published a consensus report for the US Congress--Reproducibility and Replicability in Science--which addressed a major methodological crisis in the sciences: The fact that many experiments and results are difficult or impossible to reproduce.
