introduction: biofilm forming staphylococcus epidermidis is a main causative agent of infections related to medical devices. purification and evaluation of gly-ta polysaccharide from a biofilm-forming s. epidermidis as a putative vaccine candidate were the main goals of the current study. methods: taking advantage of size exclusion chromatography procedure, glycerol teichoic acid (gly-ta) was p...

Abstract Pigmentary coloration can produce viewing angle-independent uniform colors via light absorption by chromophores. However, due to the limited diversity in changes of molecular configuration chromophores undergo color change, existing materials cannot a wide range visible with tunable saturation and transmittance. Herein, we propose novel strategy create highly We fabricated hydrogel pol...

The 2-mono and 2,6-disubstituted methyl-1,4-dihydropyridines were synthesized by reaction of morpholine, thiophenol, 8-hydroxyquinoline, 2-naphthol and 2-mercopto-1-methyl imidazole with the 2-mono bromo and 2,6-dibromo-1,4-dihidropyridines.

Escherichia coli and Salmonella typhimurium show positive chemotaxis to glycerol, a chemical previously reported to be a repellent for E. coli. The threshold of the attractant response in both species was 10(-6) M glycerol. Glycerol chemotaxis was energy dependent and coincident with an increase in membrane potential. Metabolism of glycerol was required for chemotaxis, and when lactate was pres...

The oxidation and turnover of plasma glycerol has been studied in lean and obese, fed and starving man by means of a long-term infusion of glycerol-(14)C, and the participation of glycerol in gluconeogenesis has been determined. Under none of the experimental conditions did glycerol contribute more than 10% of the total respiratory CO(2). Glycerol turnover in fed lean subjects was 106 mmoles/mi...

Rainbow smelt is a small fish that accumulates glycerol in winter as a cryoprotectant when the animal is in seawater. Glycerol is synthesized in liver from different substrates that all lead to the formation of glycerol-3-phosphate (G3P). This study assesses whether glycerol is produced by a direct dephosphorylation of G3P by a phosphatase (G3Pase) or by a cycling through the glycerolipid pool ...

We report, in this work, our study of the thermal conductivity high-viscosity nanofluids based on glycerol. Three have been prepared with different contrasts, by suspending graphene flakes, copper oxides, or silica nanoparticles pure The were thermally characterized at room temperature 3ω technique, low amplitudes oscillations. A significant enhancement is found both glycerol/copper oxide and g...

The superior quality of glycerol synthesized.from propylene (Groll, et al., 1938; Williams, 1938, 1941), as compared with glycerol obtained from fats and oils, has been reported by Williams (1938) and confirmed by studies in pharmacology (Hart, 1939) and experiments in histology (Nichols, 1941). Since glycerol is a constituent of numerous culture media for microorganisms, the value of synthetic...

BACKGROUND Malaria and dengue are two of the most common vector-borne diseases in the world, but co-infection is rarely described, and immunologic comparisons of co-infection with mono-infection are lacking. METHODOLOGY AND PRINCIPAL FINDINGS We collected symptom histories and blood specimens from subjects in a febrile illness surveillance study conducted in Iquitos and Puerto Maldonado, Peru...

legumes are rich sources of protein and consider a good alternative to make a protein films. in this study, central composite design to investigate the simultaneously effect of the grasspea protein isolates (2 - 10 percent), glycerol (0.5 - 7%) and oleic acid (0 - 2%) on properties of edible films made from grasspea protein isolates, such as thickness, density, percentage of solubility in water...
