appendicitis/protease

OBJECTIVE Serine proteases and the matrix metalloproteinases (MMPs) are key factors in the proteolytic cascade and participate in extracellular matrix (ECM) degradation. Fibrinolytic activators and inhibitors may have an effect on inflammatory cells, thereby modulating the inflammatory response. It

BACKGROUND Cathepsin B (CatB) belongs to a family of lysosomal cysteine proteases and plays an important role in intracellular proteolysis. OBJECTIVE The concentration of CatB and 20S proteasome was evaluated in the serum of children with appendicitis, before and after surgery, on a basis of an

BACKGROUND Matrix metalloproteinases (MMPs) and serine proteases are able to degrade the extracellular matrix (ECM) and modulate immune responses in the gastrointestinal tract. The purpose of this study was to investigate local proteolysis in perforated appendicitis and its association with the

BACKGROUND Thrombotic thrombocytopenic purpura (TTP) in children is a rare life-threatening syndrome, characterized by microangiopathic hemolytic anemia, thrombocytopenia with renal dysfunction, neurologic symptoms, and fever. TTP is usually caused by deficient activity of von Willebrand factor

Proteus species, members of the Enterobacteriaceae family, are usually considered commensals in the gut and are most commonly recognized clinically as a cause of urinary tract infections. However, the recent identification of Proteus spp. as potential pathogens in Crohn's disease recurrence after
