NSF International develops online resource for supplements information
ANN ARBOR, Mich. NSF International on Tuesday launched a new online resource, http://www.nsfsport.com, to provide information to help consumers, athletes and coaches choose safer, quality supplement products.
“We are pleased to see more user-friendly resources being placed in the hands of the public,” stated Liliana Begg, manager, Clean Sport Initiative. “The Clean Sport Initiative, which provides a forum for discussions on accidental doping will now have the support of value-added informational sites that provide consumers with the guidance they need when choosing nutritional supplements.”
NSF’s Athletic Banned Substances Certification Program certifies sports supplements that have met NSF’s certification guidelines and provides key preventive measures to protect against adulteration of products, verify label claims with product contents, as well as identify any banned substances in the finished product. The certification program has been recommended by key athletic organizations, including Major League Baseball, the Major League Baseball Players Association, the National Football League, the Professional Golf Association, the National Football League Players Association and the Canadian Centre for Ethics in Sports.
Mosquito gut bacteria may inhibit malaria parasite, researchers say
BALTIMORE, Md. Bacteria in the gut of a mosquito may inhibit infection of Plasmodium falciparum, the parasite that causes malaria in humans, according to researchers at the Johns Hopkins Bloomberg School of Public Health.
Scientists with the Bloomberg School’s Malaria Research Institute found that removing these bacteria, or microbial flora, with antibiotics made the mosquitoes more susceptible to Plasmodium infection because of a lack of immune stimulation. Their study is published in the May 8, edition of the journal PLoS Pathogens.
“Our study suggests that the microbial flora of mosquitoes is stimulating immune activity that protects the mosquito from Plasmodium infection,” stated George Dimopoulos, senior author of the study and associate professor with Johns Hopkins Malaria Research Institute. “The same immune factors that are needed to control the mosquito’s infection from the microbes are also defending against the malaria parasite Plasmodium. … The interplay between bacteria and the mosquito’s immune system may have significant implications for the transmission of malaria in the field where mosquitoes may be exposed to different types of bacteria in different regions. Theoretically, these bacteria could be introduced to the mosquitoes to boost their immunity to the malaria parasite and make them resistant and incapable of spreading the disease. Our current research aims at identifying those bacteria that trigger the strongest mosquito immune defense against the malaria parasite.”
Malaria kills more than one million people worldwide each year; the majority of deaths are among children living in Africa.
Herb works as anti-ulcer therapy, study shows
BEIJING A research team led by Syed Rafatullah from Saudi Arabia validated the gastric anti-ulcer properties of the herb Rocket “Eruca sativa L.” (EER) on experimentally-induced gastric secretion and ulceration in albino rats. The study was published April 28 in the World Journal of Gastroenterology.
In recent years, Rocket “Eruca sativa L.” (EER), a member of the Brassicacae family, has gained greater importance as a salad vegetable and spice, especially among Middle Eastern populations and Europeans. It is believed that plants belonging to the Brassicacae family possess diversified medicinal and therapeutic properties including inhibition of tumorigenesis, anti-ulcer and hepatoprotective activities.
Although the introduction of proton-pump inhibitors to the classic anti-ulcer therapy has revolutionized treatment of peptic ulcers and other gastrointestinal disorders, there is still no complete cure for this disease, researchers noted. It has been shown that long term use of these drugs leads to various adverse and side effects. Relapses of the malady, ineffectiveness of different drug regimens and even resistance to drugs are emerging. Thus, there is an urgent requirement to identify more effective and safe anti-ulcer agents.
Researchers found that the ethanolic extract of EER significantly and dose-dependently reduced basal gastric acid secretion, titratable acidity and ruminal ulceration in lab rats. The authors concluded that EER extract possesses anti-ulcer activities against experimentally-induced gastric lesions.
