Mammalian cells respond to bacterial lipopolysaccharide (LPS) through a cognate receptor: Toll-like receptor 4 (TLR4). The signaling pathways, which link TLR4 to the proinflammatory transcription factor nuclear factor kappaB (NF-kappaB), occur through the intracellular docking proteins MyD88 and Trif. We hypothesize that unlike antigen-presenting cells, vascular endothelial cells (ECs) lack the...

BACKGROUND Venous thromboembolism (VTE) risk models including the Davison risk score and the 2005 Caprini risk assessment model have been validated in plastic surgery patients. However, their utility and predictive value in breast reconstruction has not been well described. We sought to determine the utility of current VTE risk models in this population and the VTE rate observed in various meth...

The free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) and deep inferior epigastric perforator (DIEP) flaps involve transferring skin and subcutaneous tissue from the lower abdominal area and have many features that make them well suited for breast reconstruction. The robust blood supply of the free flap reduces the risk of fat necrosis and also enables aggressive shaping of...

Recent reports of breast reconstruction with the deep inferior epigastric perforator (DIEP) flap indicate increased fat necrosis and venous congestion as compared with the free transverse rectus abdominis muscle (TRAM) flap. Although the benefits of the DIEP flap regarding the abdominal wall are well documented, its reconstructive advantage remains uncertain. The main objective of this study wa...

A numerical study of eight configurations magnetic systems electric motors with permanent magnets for driving a tram was carried out. The magnet motor can be used as high-speed drive to replace the existing DC tram, and low-speed gearless new generation tram. most promising have been determined. By varying geometrical winding parameters each investigated models motors, mechanical characteristic...

Although experimental evidence suggests that the preliminary surgical delay procedure physiologically improves the circulation of the TRAM flap, there are no published controlled studies evaluating the clinical outcomes associated with this procedure. The purpose of this study was to evaluate the efficacy of the surgical flap delay versus no delay in consecutive patients having pedicle TRAM bre...

Abstract This article analyses the possibility of using self-driving systems in field public transport. In this study, type transport considered is tram. Today, innovative technologies are becoming publicly available. It shown that modernization artificial intelligence tram, maximum practical experience needed to improve its adaptation various external situations. The study suggests application...

Secretion of Cl(-) and K(+) in the colonic epithelium operates through a cellular mechanism requiring K(+) channels in the basolateral and apical membranes. Transepithelial current [short-circuit current (I(sc))] and conductance (G(t)) were measured for isolated distal colonic mucosa during secretory activation by epinephrine (Epi) or PGE(2) and synergistically by PGE(2) and carbachol (PGE(2) +...

BACKGROUND This study reports on the longitudinal experience and outcomes of one surgeon performing free transverse rectus abdominis musculocutaneous (TRAM) flaps on 500 consecutive patients between 1992 and 2003. METHODS A retrospective review of hospital and outpatient records was performed. Specific risk factors for successful reconstruction were reviewed, including American Society of Ane...
