It has been well-established that polarized migrating cells exhibit a stable and transient gradient of intracellular calcium concentration ([[Ca.sup.2+.sub.i]), increasing from front-to-rear, that is thought to be responsible for rear retraction. The paradox that arises is how calcium at the front of a cell catalyzes critical high-threshold calcium-dependent processes during ...

In dystrophin-deficient skeletal muscle cells, in which [Ca.sup.2+] homeostasis is disrupted and reactive oxygen species production is increased, we hypothesized that hypochlorous acid (HOCl), a strong [H.sub.2][O.sub.2]-related free radical, damages contractile proteins and the sarcoplasmic reticulum. The aim of the present study was to investigate the effects of exposure to ...
Oliveira-Pelegrin, G.R. - - 2010
Sepsis induces production of inflammatory mediators such as nitric oxide (NO) and causes physiological alterations, including changes in body temperature ([T.sub.b]). We evaluated the involvement of the central NO-cGMP pathway in thermoregulation during sepsis induced by cecal ligation and puncture (CLP), and analyzed its effect on survival rate. Male Wistar ...

Myocardial tumor necrosis factor-[alpha] (TNF-[alpha]), a proinflammatory cytokine, is a critical inducer of myocardial dysfunction in sepsis. The purpose of this review is to summarize the mechanisms through which TNF-[alpha] production is regulated in cardiomyocytes in response to lipopolysaccharide (LPS), a key pathogen-associated molecular pattern (PAMP) in sepsis. These mechanisms ...

Duchenne muscular dystrophy (DMD) is a severe muscle-wasting disease caused by the absence of the cytoskeletal protein dystrophin. Experiments on the mdx mouse, a model of DMD, have shown that mdx muscles are particularly susceptible to stretch-induced damage. In this review, we discuss evidence showing that a series of stretched ...
