closure of donor site of the flap has special problems. reduction of this site will decrease the morbidity of operation. in this study, we present our experience in donor site size reduction. methods between 2006 and 2008, 15 patients with skin and soft tissue defects underwent operation. in all patients, coverage of defect was performed with various flaps. substratum horizontal mat-tress sutur...

Species rich benthic communities have been reported from some seamounts, predominantly from the Atlantic and Pacific Oceans, but the fauna and habitats on Indian Ocean seamounts are still poorly known. This study focuses on two seamounts, a submarine volcano (cratered seamount--CSM) and a non-volcano (SM2) in the Andaman Back-arc Basin (ABB), and the basin itself. The main purpose was to explor...

Cell migration is a phenomenon that is involved in several physiological processes. In the absence of external guiding factors it shares analogies with Brownian motion. The presence of biochemical or biophysical cues, on the other hand, can influence cell migration transforming it in a biased random movement. Recent studies have shown that different cell types are able to recognise the mechanic...

Specialized areas within broad, close, cell-substratum contacts seen with reflection interference contrast microscopy in cultures of Xenopus embryonic muscle cells were studied. These areas usually contained a distinct pattern of light and dark spots suggesting that the closeness of apposition between the membrane and the substratum was irregular. They coincided with areas containing acetylchol...

Cell division of various animal cells depends on their attachment to a substratum. Dictyostelium cells deficient in type II myosin, analogous to myosin in muscle, can divide on a substratum without the contractile ring. To investigate the mechanism of this substratum-dependent cytokinesis, the dynamics of actin in the ventral cortex were observed by confocal and total internal reflection fluore...
