When CASNET (Chapter 7) evolved into the general s,vstem-building tool known as EXPERT, one of the first applications was a rheumatology consultant program called AI/Rheum (Kingsland and Lindberg, 1983). Developed collaboratively by researchers at Rutgers University and the University of Missouri, AI/Rheum quickly became large and complex, thereby complicating the process of knowledge base main...

BACKGROUND Exposure to ultraviolet (UV) radiation causes various forms of acute and chronic skin damage, including immunosuppression, inflammation, premature aging and photodamage. Furthermore, it induces the generation of reactive oxygen species, produces proinflammatory cytokines and melanocyte-stimulating hormone (MSH) and increases tyrosinase activity. The aim of this study was to evaluate ...

BACKGROUND During adaptive radiation events, characters can arise multiple times due to parallel evolution, but transfer of traits through hybridization provides an alternative explanation for the same character appearing in apparently non-sister lineages. The signature of hybridization can be detected in incongruence between phylogenies derived from different markers, or from the presence of t...

OBJECTIVES Trichomoniasis is one of the most common sexually transmitted diseases in humans and is caused by the protozoan Trichomonas vaginalis. Nowadays, increasing resistance to drugs such as metronidazole resulted in many problem, so new effective remedies are needed. In this study, we evaluate constituents of essential oil and anti-trichomonas activity of Rheum ribes. MATERIALS AND METHO...

Rheum species are medicinally important herbs, posses several type of biological activities due to the presence of anthraquinone derivatives. Several HPLC methods have been used for sepeatation of anthraquinone of Rheum Species. In most cases anthraquinones were separated using C18 column as a stationary phase, acetonitrile, water and methanol with or without acid as mobile phase at 1.0 ml/min ...
