Alcohol consumption cutoffs are unreliable in the setting of Roux-en-Y gastric bypass (RYGB) surgery, researchers report. "Because RYGB changes the way that alcohol is metabolized and experienced, such that alcohol has a stronger effect post-surgery, we hypothesized that the best alcohol frequency and quantity cutoffs for identifying alcohol problems would be lower among post-surgery patients," said Dr. Wendy C. King from University of Pittsburgh
GPs are ordering more than three times as many tests diagnostic for their patients as they were 15 years ago as they now provide more services previously provided by hospitals and monitor more patients with chronic diseases, shows a study published in The BMJ today.
Viruses are Nature’s delivery vehicles. Millions of years of evolution have molded them into remarkable machines capable of performing a monumental task vital to their survival: the delivery of genetic material into other organisms.
Surgery-induced neuroinflammation plays an important role in postoperative cognitive dysfunction (POCD). Gut microbiota is a key regulator of neurological inflammation. Nurturing with prebiotics is an effective microbiota manipulation that can regulate host immunity and cognition.
The aim of the present study was to test whether administration of the prebiotic Bimuno® (galactooligosaccharide (B-GOS) mixture) could ameliorate POCD and attenuate surgery-induced neuroinflammation through the microbiota-brain-axis.
It's fitting that one of the first experiments to be conducted by Canada's first astronaut in space since 2013 – will be a research project designed by a Canadian university. If all goes well, one of his first tasks during his six-month tour will involve conducting experiments on himself, as part of a research program designed by York University's Center for Vision Science.
Injuries are part of the game. That is a common refrain in sports, usually referring to the athletes. But sometimes it is the spectators who get hurt. "You do not expect to be injured when you attend a sporting event as a spectator," said Amit Momaya, a sports medicine orthopaedic surgeon. "You certainly do not expect to die, yet there are any number of cases where spectators are injured, some fatally, at sporting events ."
The Union government's policy push for developing health and wellness centers is a well thought out step for renewing focus on comprehensive primary care. The experiences of several countries show that investing in primary healthcare leads to allocative efficiency by bringing to a range of preventive, curative, promotive and rehabilitative services closer to the people. Countries with greater primary care orientation have a lower rate of mortality and better health outcomes .
"Preventing the threat of use of biological agents is a key priority for Sri Lanka," stressed Sri Lanka Permanent Representative in Geneva Ambassador Azeez, addressing the International Seminar convened by the Geneva Center for Security Policy (GCSP) and the Implementation Support Unit (ISU) ) of the Biological Weapons Convention (BWC) on 'The importance of disease surveillance and alert mechanisms: Lessons for the BWC' held on 20 November.
Supercomputer simulations show that at the atomic level, material stress does not behave symmetrically. Widely-used atomic stress formulae significantly underestimate stress near stress concentrators such as dislocation core, crack tip, or interface, in a material under deformation. Supercomputers simulate force interactions of Lennard-Jones perfect single crystal of 240,000 atoms. Study findings could help scientists design new materials such as glass or metal that does notice up.
RUDN chemists synthesized a range of biologically active molecules called chromones and demonstrated their use in the treatment of Alzheimer's disease. The results of the work were published in the Bioorganic & Medicinal Chemistry journal.
A commonly used biomarker of kidney disease may also indicate lung problems, particularly COPD, or chronic obstructive pulmonary disease, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
An international research team has discovered a mechanism that regulates the regeneration of the insulating layer of neurites. This insulation coating, also referred to as myelin sheath, is crucial for rapid signal transmission among cells. Damages to the myelin sheath, such as are caused by multiple sclerosis, can considerably inhibit the function of the nervous system.
