Immunity against cytomegalovirus (CMV) is initiated after its recognition by Toll-like receptor 2 (TLR2). We assessed the association between a single-nucleotide polymorphism (SNP) that impairs TLR2 function and CMV disease in a cohort of 737 liver recipients. Ninety-two of 737 patients (7.1%, 10.9%, 12.3%, and 12.5% by 3, 6, 12, and 24 months, respectively) developed CMV disease. Kaplan-Meier ...

To examine the correlations among environmental perceptions, motivational beliefs, and self-regulating learning of Tehran high school third-year boys, a causal model was used and 685 students were selected by multistage cluster-sampling method. The motivated Strategies for Learning Questionnaire (Pintrich & De Groot, 1990), Students' Achievement Goal Orientations (Midgley, Kaplan, Middleton, Ma...

Alopecia Areata (AA) is a common autoimmune disease characterized by the loss of immune privilege hair follicle. CD8+ T cells have been identified as main effectors in AA, however, little known about role regulatory (Tregs) and why they fail to control disease. The imbalance Tregs: thought influence development many diseases. Enrichment compartment has gaining momentum field currently there are...

In a recent paper G.V. Stupakov and P. Chen[1] have advanced the possibility of beam-beam interaction suppression in circular colliders for heavy particles such as muons and protons, by introducing a plasma at the interaction point. More recently and independently, A. Skrinsky [2] has suggested to use flowing liquid Li for the same purpose in a muon collider. This is an alternative that is only...
