Lethality Of H1N1 Influenza Virus Increasing According To Latest Analysis Of Virus Peptide Genomic Data
An analysis of the latest peptide genomic data for the H1N1 influenza virus indicates that the current global outbreak of H1N1 is increasing in its capacity for lethality. The new sequence data on PubMed of the past two weeks through June 10, 2009 showed an increase in the Replikin Count* of the Replikin Lethality Gene in the pB1 genomic area from a mean of 2+/-0.2 in 2008 to a mean of 3.2+/-3.7 in 2009 (p

Medical Study Establishes First-Ever Long-Term Benefits For Macular Degeneration Sufferers Using Macular Health Vitamin Supplement
According to the World Health Organization (WHO), age-related macular degeneration (AMD) ranks third as a cause of visual impairment. It is the primary cause of visual impairment in industrial countries with a blindness prevalence of 8.7 percent. A new medical study indicates, however, that with the use of the Macular Health vitamin supplement there is a way to preserve the vision of millions of aging adults suffering from AMD.

Ginseng -- Nature's Anti-Inflammatory?

Laboratory experiments have demonstrated the immunological effects of ginseng. Researchers writing in BioMed Central"s open access Journal of Translational Medicine have shown that the herb, much used in traditional Chinese and other Asian medicine, does have anti-inflammatory effects. Allan Lau led a team of researchers from the University of Hong Kong who identified seven ginseng constituents, ginsenosides, which showed immune-suppressive effects. He said, "The anti-inflammatory role of ginseng may be due to the combined effects of these ginsenosides, targeting different levels of immunological activity, and so contributing to the diverse actions of ginseng in humans". The scientists treated human immune cells with different extracts of ginseng. They found that of the nine ginsenosides they identified, seven could selectively inhibit expression of the inflammatory gene CXCL-10. Lau concludes, "Further studies will be needed to examine the potential beneficial effects of ginsenosides in the management of acute and chronic inflammatory diseases in humans". Uniquely, the researchers were able to holistically test the ginseng extract"s immune effects by using sophisticated purification technologies to identify individual constituents and define their bioactivity using genomics and bioactivity assays. After that, they reconstituted them back into a whole extract with definable individual ginsenosides for re-confirmation of effects. This potentially opens up a vigorous methodology to study medicinal herbs with state-of-the-art technologies.
