U of M study: Health food supplement may curb addiction of pathological gamblersSeptember 12, 2007University of Minnesota researchers have discovered that a common amino acid, available as a health food supplement, may help curb pathological gamblers' addiction. In a recent eight-week trial, 27 people were given increasing doses of the amino acid, N-acetyl cysteine, which has an impact on the chemical glutamate - often associated with reward in the brain. At the end of the trial, 60 percent of the participants reported fewer urges to gamble. The research will be published in the Sept.15, 2007 issue of Biological Psychiatry. "It looks very promising," said Jon Grant, J.D., M.D., a University of Minnesota associate professor of psychiatry and principal investigator of the study. "We were able to reduce people's urges to gamble." Those who responded well in the first round of the study were asked to continue to participate in a double-blind study - a testing method where neither the researcher nor subjects know who is in the control group until the study is finished. Of the 16 who responded to the amino acid the first time around, 13 agreed to continue in the double-blind study (three didn't want to risk quitting the drug) for an additional six weeks. About 83 percent who received the supplement, continued to report fewer urges to gamble. Nearly 72 percent of those who took the placebo went back to gambling. Similar studies using N-acetyl cysteine have shown its ability to curb drug addictions in animals, and a current University of Minnesota study conducted by Grant is investigating whether the drug could help methamphetamine users quit. "This research could be encouraging for a lot of addictions," Grant said. This pilot study is the first to examine the efficacy of a glutamate-modulating agent in the treatment of pathological gamblers, making the findings fairly significant, Grant said. Because subjects knew they were taking a supplement during the first phase of the study and since there was a relatively small number of subjects in the double-blind portion, a larger study is warranted to confirm the validity of these findings. University of Minnesota researchers are currently seeking a federal grant to fund it. University of Minnesota |

What cures your aches might prevent cancer Mayo Clinic Cancer Center has begun three clinical studies looking at the use of nonsteroidal anti-inflammatory drugs (NSAIDs) to prevent cancer - colon, esophageal or lung. Brewing up potential anti-cancer drugs from green tea Drinking green tea has a protective effect against some forms of cancer but drinking large amounts can increase the risk of birth defects such as spina bifida - according to previous epidemiological studies. Red palm oil as a means of combating Vitamin A deficiency More than 250 million under-fives in the world are at risk from vitamin A deficiency. Such deficiency, currently the primary cause of avoidable blindness, provides the conditions for diseases to take hold, leading to high death rates among these young children. Several strategic options exist for combating these deficiencies: medicinal supplements, vitamin A enrichment of foods at industrial or community scale, or diet diversification founded on the use of locally available resources. The latter approach was adopted, in a pilot project for promoting unrefined red palm oil in Burkina Faso. IRD scientists from the research unit "nutrition, diet, societies", working jointly with Canadi Plants Control The Molting Of Insects A special place on the market of food supplements belongs to ecdysteroid-containing preparations that are helpful as a tonic for sportsmen during intensive training sessions, for people of various professions connected with physical and psychological stresses, and also for elderly people. Ecdysteroids heal wounds and burns. A plant containing very high concentrations of ecdysteroids has been found by a team headed by Vladimir Volodin from the Institute of Biology in Syktyvkar. This is saw-wort (Serratula coronata). Its leaves contain more significant amounts of the active component than the roots of rhaponticum (Leuzea carthamoides) used as a medicinal plant in the former USSR. A saw-wort p Leprosy, tuberculosis, and peanuts Nitric oxide is a natural part of the body’s immune defense. Linköping University researcher Thomas Schön has studied this compound in connection with the skin disease leprosy and the lung disease tuberculosis. The Swedish researcher has found that nitric oxide probably contributes to the disease in the case of leprosy but, on the other hand, plays a positive role in protecting against tuberculosis. This role can be reinforced by adding a supplement of arginine, which is found in peanuts, for example. Probiotics, mentioned on the labels of food products, often cannot be detected in the food. In the course of a PhD research, fifty-five European probiotic products were screened for the identity and quantity of the bacterial strains included in these products. A probiotic is a living microorganism (bacteria or yeast) that upon intake, improves the health of the host by means of a number of positive effects in that host. These ‘good’ microorganisms that usually belong to the group of the ‘lactic acid bacteria’ (such as Lactobacillus and Bifidobacterium, better known as ‘active bifidus’), can be included in a whole array of products, which then are named ‘probiotic products’. The most popular probiotic products are dairy drinks, althoug LONG-TERM BENEFITS OF GLUCOSAMINE SULPHATE FOR OSTEOARTHRITIS (pp 247, 251) The symptoms and changes to joint structure associated with osteoarthritis could be moderated by the long-term effects of glucosamine sulphate, conclude investigators in a study published in this week's issue of THE LANCET. Osteoarthritis is a major cause of disability and is among the most frequent forms of musculoskeletal disorders. Several short-term to medium-term clinical trials in osteoarthritis have shown the symptom-modifying effect of glucosamine sulphate and its good safety profile. However, the need for long-term clinical trials with this compound has been emphasised. Consequently, treatment of osteoarthritis has been limited to short-term symptom control.
