We examined the effects of the developmental milieu on the capacity of B cells to undergo immune response gene-controlled, T cell-dependent polyclonal proliferation. Although I-Aq poly(Glu60 Ala30 Tyr10)n (GAT)-nonresponder T cells developing in a responder environment become phenotypic GAT-responders, I-Aq B cells remain unresponsive to GAT, even after maturation in a GAT-responder animal. Con...

OBJECTIVES In the current research, we have studied the general composition of noncommercial alcohol samples to ident...

Purpose: Sub-acromial impingement syndrome (SAIS) is one of the most common causes shoulder pain and affects joint proprioception. The closed kinetic chain (CKC) exercises with sling are more effective safer than open (OKC) exercises. This study aimed to compare effectiveness OKC total-body resistance (TRX) training on position sense (JPS) in overhead athletes (SIS). Methods: article was a rand...
