background and objectives: multiple sclerosis is an inflammatory disease of the central nervous system. this is due to migration of peripherally activated lymphocytes to central nervous system leading to inflammatory lesions. however, liver has an anti-inflammatory microenvironment. myelin expression in the liver of transgenic mice suppresses inflammatory lesions within central nervous system. ...

Silica boron sulfonic acid [SiO2–B(OSO3H)3] as an inexpensive, reusable, and Lewis and Brønsted acid catalyst was successfully synthesized, and used for the one-pot three-components synthesis of biologically active substituted Hantzsch 1,4-dihydropyridine derivatives  in the absence of solvent at 90ºC. Silica boron sulfonic acid is attractive and efficient, because it plays in two role as a Lew...

Jockusch showed that 2-generic degrees are downward dense below a 2-generic degree, but in the case of 1-generic degrees Kumabe, and independently Chong and Downey constructed a minimal degree computable from a 1-generic degree. We explore the tightness of these results. We solve a question of Barmpalias and Lewis-Pye by constructing a minimal degree computable from a weakly 2-generic one. The ...

Immunogenetic mechanisms operating within the immune system are known to influence cytokine profiles and disease susceptibility. Yet the role of the individual's neurohormonal background in these processes remains undefined. Hormonal imbalances are documented in immune-related diseases, but it is unclear whether this represents a secondary phenomenon or a primary "defect" related to specific ne...

BACKGROUND AND AIMS A mouse model was established to compare colonization by the H. pylori Sydney strain SS1 with several clinical isolates expressing different Lewis antigens on their surface. In addition, both humoral and cell mediated immune responses were determined for different H. pylori strains. METHODS Mice were inoculated intragastrically separately with the Sydney strain as well as ...
