The (Cu,Mn,Co)3O4 (CMC) spinel layer is useful in inhibiting Cr vaporization that deteriorates the solid oxide fuel cell performance. effectiveness of suppressing volatile species from metallic interconnects strongly dependent on density, which influenced by particle size distributions and agglomerations powders. Considering material properties were synthesizing conditions, this study elucidate...

Rochalimaea quintana was isolated from the blood of a French human immunodeficiency virus-infected patient with bacillary angiomatosis. The isolate showed the typical growth characteristics of Rochalimaea species and was inert when typical biochemical testing was used. The purpose of the present work was to characterize and compare this new isolate with reference strains of R. quintana, Rochali...

Citrate-soluble extracts of chicken sciatic nerve were fractionated biochemically and added to cultures of embryonic chicken skeletal muscle in order to identify the component that exerted trophic influences on the muscle. A protein fraction that expressed trophic activity was obtained by ion-exchange chromatography on DEAE-cellulose followed by gel filtration on Sephadex G-100 superfine. This ...

Poly(1,8-octanediol-co-citrate) (POC) is a biocompatible, biodegradable elastomer with potential application for soft tissue applications such as cartilage. For chondrogenesis, permeability is a scaffold design target that may influence cartilage regeneration. Scaffold permeability is determined by many factors such as pore shape, pore size, pore interconnectivity, porosity, and so on. Our focu...

Bovine Factor VIII (antihemophilic factor) has been purified approximately lO,OOO-fold with an over-all yield of 10 to 15%. The purification procedure involves BaS04, kaolin, and bentonite adsorption to remove contaminants, ethanol, polyethylene glycol, and /Y-alanine fractionation, calcium citrate-cellulose chromatography, concanavalin A precipitation, and an Agarose gel filtration step. The f...

An alkalophilic bacterium, Bacillus cereus produced an extracellular alkaline protease, which was found to be active at high temperature and pH range, suitable for commercial laundry detergents. B. cereus protease was partitioned in different aqueous two-phase systems such as PEG/dextran, PEG/potassium phosphate, PEG/sodium citrate, PEG/magnesium sulphate and PEG/sodium dihydrogen phosphate and...

Human Factor VIII/von Willebrand factor, purified by calcium citrate-cellulose chromatography and 4% agarose gel filtration was subjected to sodium dodecyl sulfate gel electrophoresis on gels containing 2% acrylamide and 0.5% agarose. We find a series of multimers of which the apparent molecular weight of the higher members was congruent with5 million. The higher multimers were isolated by 2% a...

Rhodopseudomonas gelatinosa grows on citrate anaerobically in the light. Under aerobic conditions citrate cannot be utilized. Citrate is rapidly fermented by Rps. gelatinosa in the dark, and this fermentation is associated with limited growth (one generation). Anaerobically in the light citrate is decomposed much faster than its catabolic products can be used for the synthesis of cellular mater...

Electroaddressing of biological components at specific device addresses is attractive because it enlists the capabilities of electronics to provide spatiotemporally controlled electrical signals. Here, the electrodeposition of calcium alginate hydrogels at specific electrode addresses is reported. The method employs the low pH generated at the anode to locally solubilize calcium ions from insol...

The effectiveness of sodium citrate and sodium citrate/ranitidine were compared in two randomised groups of elective caesarean patients during the various phases of anaesthesia. The mean pH values (3.5, 3.3, 3.6) were lower in the citrate group compared to the citrate/ranitidine group (6.1, 6.3, 5.9). The percentage of patients with pH values less than 2.5 was 40% in the citrate group compared ...
