The city lifestyle has been criticised as a key reason that children are disconnected from nature. This has led to an unhealthy lifestyle in regard to active play and eating habits. Even worse, many young children do not feel well psychologically they are often stressed and depressed. 16% of preschoolers in Hong Kong and up to 22 percent in China show signs of mental health problems.
Astrocytes, 'caretaker' cells that surround and support neurons in the brain, play a much more important role in circadian rhythms, the body's 24-hour internal clock, than previously understood.
Postdural puncture headache (PDPH) is a complication of spinal anesthesia or lumbar puncture and is an unpleasant experience for the patient as well as the anesthetist. It is thought to result from meningeal traction related to low cerebrospinal fluid (CSF) pressure or cerebral vasodilation as an indirect effect of decreased CSF pressure. A clinical experience with neostigmine prompted the comparison of the efficacy of neostigmine and conservative management for the treatment of PDPH.
Researchers have had a rare opportunity to see how conditions on the International Space Station translated to changes in gene expression by comparing identical twin astronauts one of the twins spent close to a year in space, while the other remained on Earth.
The visual system is probably the best understood part of the brain. Over the past 75 years, neuroscientists have assembled a detailed account of how light waves entering your eyes allow you to recognize your grandmother's face, to track a hawk in flight, or to read this sentence. But a new study by UC San Francisco researchers is calling a fundamental aspect of vision science into question, showing that even the best-studied parts of the brain can still hold plenty of surprises.
Rutin, a bioflavonoid (plant pigment) found in certain vegetables and fruits, protects mice against snake venom by minimizing bleeding and inflammation, according to a study performed at the Butantan Institute, a research institution belonging to the government of São Paulo State in Brazil.
The expectation of constant availability due to our 21st-century, technology-driven lifestyles can be exhausting. Throw in the laundry, shopping, and social obligations, and finding the time to exercise can seem impossible.
Should death be defined in strictly biological terms as the body's failure to maintain the integrated functioning of respiration, blood circulation, and neurological activity? Should death be declared on the basis of severe neurological injury even when biological functions remain intact?
Alcohol is ubiquitous in Western society, and rates of excessive use among adults remain high. Excessive alcohol consumption is an established risk factor for atrial fibrillation (AF), but what are the effects of moderate and mild consumption on AF?
Findings from a Western-led study into the biggest concerns faced by musicians with hearing loss should strike a chord with educators and conductors and result in new ways to lead ensembles, researchers explained.
Drugs called thiazolidinediones (TZDs) reverse insulin resistance in patients with type 2 diabetes by targeting the activity of a receptor protein. However, an array of side effects, including weight gain, edema, and high cholesterol, limits their use in the clinic.
