The complement system is a proteolytic cascade in blood plasma and a mediator of innate immunity, a nonspecific defense mechanism against pathogens. There are three pathways of complement activation: the classical pathway, the lectin pathway, and the alternative pathway. All of these pathways generate a crucial enzymatic activity that, in turn, generates the effector molecules of complement. The main consequences of complement activation are the opsonization of pathogens, the recruitment of inflammatory and immunocompetent cells, and the direct killing of pathogens. Blood coagulation is another series of proenzyme-to-serine protease conversions, culminating the formation of thrombin, the enzyme responsible for the conversion of soluble fibrinogen to the insoluble fibrin clot. Protease-activated receptors, such as those activated by thrombin, are members of G protein-coupled receptors and function as a mediator of innate immunity. The kallikrein-kinin system is an endogenous metabolic cascade, triggering of which results in the release of vasoactive kinins (bradykinin-related peptides). Kinin peptides are implicated in many physiological and pathological processes including the regulation of blood pressure and sodium homeostasis, inflammatory processes, and the cardioprotective effects of preconditioning.

Based on the defense cascade model, we developed the Shutdown Dissociation Scale (Shut-D; Schauer & Elbert, 2010), which is able to meet the new requirements for assessing the expression of dereali...

Maine’s public defense agency operated without clear leadership and with few written policies that caused a cascade of problems with its finances and oversight of attorneys for the state’s poorest defendants, a scathing report released Monday by the state’s oversight agency shows.

Parc Diderot is a hidden gem in the busy bustling La Defense business district of Paris. Slightly off the beaten track and nestling among the glass towers, water ripples and roars as a giant wave. Water integrate remarkably well into the surrealist landscape imagined by Alain Provost, and forms a giant wave framed by pink granite. “The cascade is stunning”, but “chut”…keep it secret.
