Osteoporosis, a metabolic bone disease, is characterized by an excessive formation and activation of osteoclasts. Anti-catabolic treatment using natural compounds has been proposed as a potential therapeutic strategy against the osteoclast related osteolytic diseases. In this study, the activity of berberine sulfate (an orally available form of berberine) on osteoclast differentiation and its u...
OBJECTIVE To refresh the athletic trainer's knowledge of articular cartilage biomechanics, physiology, and structure and explore the role of glucosamine sulfate in treating articular cartilage pathologic conditions, including supplementation methods and clinical outcomes. DATA SOURCES We searched MEDLINE from 1989 through 2000 and SPORT Discus from 1975 through 2000 using the following key wo...
Abstract This article investigates utilization of polypropylene microfibers as reinforcement in geopolymer concrete to enhance the ductility characteristics since is considered a brittle material. The were added at fiber volume content 0.5%, 1.0%, and 1.5%. In this article, slump test compressive strength tested for concretes measure effect on concretes. Also, static flexural dynamic loading ap...
Concretes, depending on their application, may be exposed to elevated temperatures during lifetime, especially when placed near or in a furnace an accidental fire. The thermal stability of alkali-activated mortars and hydrated prepared using ladle slag two different aggregates was studied. A commercial calcium aluminate cement used as comparison for the properties after exposure up 1000°C. All ...
Ureaplasma urealyticum is an organism considered susceptible to tetracycline. Ten tetracycline-resistant (Tcr) clinical isolates and Tcr serotype 9 were examined. All contained DNA sequences homologous to the streptococcal determinant tetM. They differed from each other on sodium dodecyl sulfate-polyacrylamide gel electrophoresis, Southern blots, and immunoblots and appeared to represent differ...
The S-nitrosylated proteoglycan glypican-1 recycles via endosomes where its heparan sulfate chains are degraded into anhydromannose-containing saccharides by NO-catalyzed deaminative cleavage. Because heparan sulfate chains can be associated with intracellular protein aggregates, glypican-1 autoprocessing may be involved in the clearance of misfolded recycling proteins. Here we have arrested an...
