BACKGROUND Adipose tissue has been identified as an endocrine organ secreting adipokines involved in metabolic and inflammatory pathways. Adiponectin, an anti-inflammatory adipokine, is reduced in sepsis. High Molecular Weight (HMW) adiponectin, the biologically most relevant molecule, has been investigated very little in human sepsis. Zinc-alpha2-glycoprotein (ZAG) is a novel adipokine and its...
PURPOSE To develop new blends of emulsification-resistant silicone oil based on high molecular weight (HMW) silicone oil for use as an endotamponade in vitreoretinal surgery. METHODS Viscosity and elasticity of various silicone oil blends (Siluron 1000, Siluron 2000, Siluron 5000, 7% HMW + Siluron 1000, 10% HMW + Siluron 1000, and 15% HMW + Siluron 1000; Fluoron GmbH, Ulm, Germany) were measu...
High molecular weight (HMW) kininogen, the cofactor for activation of the contact system of plasma proteolysis, transports and optimally positions prekallikrein and factor XI on a negatively charged surface, allowing those zymogens to be activated by surface-bound factor XIIa. HMW kininogen circulates in plasma as a procofactor that, after cleavage by kallikrein or factor XIIa, gains ability to...
High-molecular-weight (HMW) protein from human cataractous lenses, isolated by differential centrifugation, was deaggregated in 7M urea and then reaggregated in either the presence or absence of 10 mM CaCl2. Over 90% of the material reaggregated in the presence of calcium appears to have a size greater than 50 X 10(6) daltons. By contrast, only 20% to 25% of the material reaggregated in the abs...
RATIONALE Percutaneous aortic valve procedures are a major breakthrough in the management of patients with aortic stenosis. Residual gradient and residual aortic regurgitation are major predictors of midterm and long-term outcome after percutaneous aortic valve procedures. We hypothesized that (1) induction/recovery of high molecular weight (HMW) multimers of von Willebrand factor defect could ...
PURPOSE The aim of this study was to investigate high molecular weight hyaluronan (HMW-HA) protection on human corneal epithelial (HCE) cells against ultraviolet B (UVB) radiation-induced toxic effects. METHODS The HCE cell line was incubated with HMW-HA or phosphate-buffered salt solution (PBS), rinsed, and exposed to UVB radiation. Cell viability, reactive oxygen species (ROS) and glutathio...
To measure the in vivo secretion of high molecular weight (HMW) transforming growth factor (TGF)beta by Reed-Sternberg cells from patients with nodular sclerosing Hodgkin's disease, we studied the urine samples from untreated patients. The urinary proteins did not promote the proliferation of NIH-3T3 cells in monolayer culture and contained similar amounts of total TGF activity when compared wi...
High-molecular-weight polycyclic aromatic hydrocarbons (HMW-PAHs) are natural components of fossil fuels that are carcinogenic and persistent in the environment, particularly in oil sands process-affected water (OSPW). Their hydrophobicity and tendency to adsorb to organic matter result in low bioavailability and high recalcitrance to degradation. Despite the importance of microbes for environm...
This study is designed to investigate the biodegradation of high molecular weight (HMW) lignin under sulfate reducing conditions. With a continuously mesophilic operated reactor in the presence of co-substrates of cellulose, the changes in HMW lignin concentration and chemical structure were analyzed. The acid precipitable polymeric lignin (APPL) and lignin monomers, which are known as degradat...
BACKGROUND Little is known regarding the associations between high-molecular-weight (HMW-) adiponectin, leptin and soluble leptin receptor (sOB-R) and metabolic syndrome (MetS) in Chinese. Also few studies elucidate the effects of inflammation and body fat mass on the relations. METHODS Plasma HMW-adiponectin, leptin and sOB-R were measured among 1055 Chinese men and women (35∼54 yrs). Whole ...
