Study demonstrates improved mobility, less pain, in patients with osteoarthritis
Osteoarthritis (OA) is a progressive, degenerative joint disease estimated to affect more than 21 million individuals in the United States. The Arthritis Foundation reports that arthritis is the leading disability of Americans resulting in over 39 million medical visits per year and $65 billion in medical expenses and lost wages. This condition is characterized by erosion of articular cartilage, caused by
In the first known study of the absorption and anti-tumor effects of green and black tea polyphenols in human tissue, researchers at the University of California at Los Angeles were able to detect tea polyphenols in prostate tissue after a very limited consumption of tea.
More importantly, the scientists found that prostate cancer cells grew more slowly when placed in a medium containing blood serum of men who had consumed either green or black tea for five days compared to serum collected
No further studies should be carried out to compare the effectiveness of oral rehydration and intravenous therapy for treating children who are dehydrated after suffering from diarrhoea, write researchers in BMC Medicine this week. Their systematic review of published research concludes that current guidelines recommending oral rehydration therapy as a first course of treatment are correct.
The researchers, from University of Alberta and Stollery Children’s Hospital, studied 14 randomised c
Wearing protective helmets during sports can affect performance, according to a new study from Northumbria University.
Tests were carried out on a group of young male cricketers and researchers investigated the physical and mental demands during an intense batting practice over eight overs when wearing a standard non-vented safety helmet and when not wearing a helmet at all.
The research revealed that wearing helmets led to significant attentional impairments and slower re
Humans can affect marine life in unexpected ways, as when large numbers of seals succumbed to canine distemper virus in 2000, presumably contracted from domestic dogs. Such human incursions cause even more damage by exacerbating the effects of naturally occurring parasitic and pathogenic diseases. While all indicators point to a real increase in disease in marine organisms, scientists have no baseline data to measure these increases against and so cannot directly test whether marine diseases are gen
12 month quality of life study with Parkinson’s patients shows surprising results
Patients with Parkinson’s disease who thought they had received a transplant of human neurons into their brains–but who really hadn’t–reported an improved quality of life one year later.
In the April issue of the Archives of General Psychiatry, research reported by Dr. Cynthia McRae of the University of Denver’s College of Education provides strong evidence for a significan
Rochester expert warns of toxicity in new wave of science
Nanotechnology, a science devoted to engineering things that are unimaginably small, may pose a health hazard and should be investigated further, warns a University of Rochester scientist and worldwide expert in the field, who received a $5.5 million grant to conduct such research.

Over the next two years, researchers at Binghamton University and partnered institutions will be helping to protect life as we know it. While the claim might sound extreme, keep in mind that they will be working to improve the design and energy efficiency of data centers.
Data centers. Thousands of them. All processing vital information, critically important to much that drives our daily lives– from world financial markets, government and military operations, business and industry, worldwi
Study’s findings contradict long-held belief that penicillin is best for the job
Pediatricians treating a child who has strep throat should reconsider the role of penicillin given that a newer class of antibiotics called cephalosporins are three times more effective, according to a study being published in the April issue of Pediatrics. The findings will spark widespread debate, because they contradict long-established guidelines from the American Academy of Pediatrics, American Heart
Risk of complications of pregnancy in women with type 1 diabetes: nationwide prospective study in the Netherlands – BMJ Online First Publication
Women with diabetes are at an increased risk of pregnancy complications, even if their diabetes is well controlled, according to new research. These findings suggest that the current criteria for strict blood sugar (glycaemic) control before and during pregnancy are not good enough.
This study will be available on bmj.com on Monday 5 April
Consumer trust in food is high in the United Kingdom, Denmark, and Norway, but low in Italy and Portugal and relatively low in Germany. Research also shows that consumers in these countries are most sceptical about meat products, fast-food outlets and food processors. These findings are revealed in the recently published study “Trust in Food in Europe, A Comparative Analysis”. The research presents data from surveys completed in the above mentioned six countries. The study was conducted as part of th
How molecules are linked together to form liquid water is the subject of a groundbreaking study due to appear Thursday, Apr. 1 in Science magazine’s advance publication web site Science Express. The investigation entitled The Structure of the First Coordination Shell in Liquid Water summarizes the results of an international collaboration headed by researchers at Stockholm University and the Stanford Linear Accelerator Center (SLAC) in California. The international team of researchers, which also inv
New studies by Howard Hughes Medical Institute researchers at The Rockefeller University show that the appetite-regulating hormone leptin causes rewiring of neurons in areas of the brain that regulate feeding behavior.
The discovery is another important clue about how leptin exerts its effects on the brain to cause decreased food intake and increased energy expenditure, said the researchers. The research also suggests that natural variability in the “wiring diagrams” of the neural feeding ci
Work could lead to improved machine vision systems, more
MIT scientists are reporting new insights into how the human brain recognizes objects, especially faces, in work that could lead to improved machine vision systems, diagnostics for certain neurological conditions and more.
Look at a photo of people running a marathon. The lead runners’ faces are quite distinct, but we can also make out the faces of those farther in the distance. Zoom in on that distant runner, how
In a study of Han Chinese patients, researchers have for the first time directly linked a gene of the immune system to a severe adverse drug reaction called Stevens-Johnson syndrome (SJS), according to a Duke University Medical Center medical geneticist and collaborators in Taiwan.
The sometimes fatal condition is characterized by a blistering rash that can lead to detachment of the skin and inflammation of the gastrointestinal and respiratory lining. More than 100 drugs — including antibi
The results and use of the model may have implications for cancer therapy
Zebrafish may prove to be an invaluable animal model with which to screen the effects of radiation, Jefferson Medical College researchers have found.
