Platelet adhesion and aggregation during hemostasis and thrombosis are usually limited to sites where the integrity of the vessel wall is disrupted. The high concentration of platelet agonists within these sites represents a putative control mechanism for targeting platelet activation. Although much has been learned about the intracellular signaling systems controlling platelet activation, our ...

PURPOSE Cyclin B1 plays an important role as a mitotic cyclin in the G(2)-M phase transition during the cell cycle. The aim of the present study was to elucidate the biological significance of cyclin B1 expression in squamous cell carcinoma (SCC) of the esophagus. EXPERIMENTAL DESIGN We analyzed immunohistochemically the expression of cyclin B1 in the tumor specimens from 120 patients with SC...

BACKGROUND The human immunodeficiency virus (HIV) pandemic has brought about a resurgence in tuberculosis (TB), especially in developing countries.
