Heavy metal ions can accumulate in the area’s crop harvest, such as rice, via a tight binding with protein. Such binding paves great difficulties to remove heavy metal ions. This study aims to remove cadmium from contaminated rice protein using rhamnolipid biosurfactant together with Pluronic F...
Cadmium removal from aqueous solution by polyelectrolyte enhanced ultrafiltration (PEUF) with relatively low transmembrane pressure was investigated at varying conditions of polyelectrolyte and cadmium concentrations, transmembrane pressure, ionic strength and pH. The poly(ammonium acrylate), wi...
Poly(butyl acrylate-co-fluorinated acrylate)-graft-natural rubber was successfully prepared via emulsion graft copolymerization and applied as a compatibilizer for improving phase compatibility and toughness of natural rubber/poly(butyl acrylate-co-fluorinated acrylate) films. From graft copolym...
This work describes the construction and evaluation of a microflow-analyzer with an in-chip cadmium column used to determine total nitrate and nitrite ion concentrations in freshwater. Deep UV photolithography in urethane-acrylate photoresist was used to create channels (390 μm deep and 410 μm...
Decreased thiamine and reduced activity of thiamine diphosphate (ThDP)-dependent 2-oxoglutarate dehydrogenase (OGDH) cause neurodegeneration. We hypothesized on concerted cell-specific regulation of the thiamine metabolism and ThDP-dependent reactions. We identified a smaller thiamine pool, a lo...
The effect of sulfate presence on reductive dechlorination of chlorinated ethenes has been a matter of conflict among the limited reports found in literature. This paper aims to clarify the misconceptions regarding the performance of trichloroethene biotransformation under sulfate reducing condi...
Ensuring continuous intracellular supply of thiamine is essential to maintain metabolism. Cellular homeostasis requires the function of the membrane bound thiamine transporters THTR1 and THTR2. In the absence of increased dietary intake of thiamine, varying intracellular levels to meet metabolic...
Biomimetic nanocarriers are emerging as efficient vehicles to facilitate dietary absorption of biomacromolecules. In this study, two vitamins, thiamine and niacin, are employed to decorate liposomes loaded with insulin, thus facilitating oral absorption via vitamin ligand–receptor interactions....
SummaryThis study examines the effect of thiamine (TH) and thiamine pyrophosphate (TPP) on epileptic episode model induced in rats with caffeine. Animals were divided into groups and given TH or TPP at doses of 10, 30 or 50 mg/kg intraperitoneally. Subsequently, all animal groups were injected i...
Thiamine has fundamental role in energy metabolism. The organs mostly sensitive to the lack of thiamine levels in the body are the nervous system and the heart. Thiamine deficiency causes symptoms of polyneuritis and cardiovascular diseases. Because of its importance in the metabolism of carbohy...
Lipid nanoparticles have been used for carrying different therapeutic agents because of the advantage in improved absorption, bioavailability, targeted deliveries and reduction in the quantity of drugs required. The aim of the study was to prepare and characterize nanoliposomes containing thiami...
Thiamine is a vitamin whose deficient can result in multiorgan symptoms. We described an 18% prevalence of clinical thiamine deficiency after gastric bypass surgery. Our hypotheses are that individuals with medically complicated obesity frequently have clinical thiamine deficiency and that diabe...
The densities and viscosities of thiamine hydrochloride (vitamin-B1) in aqueous tetrabutylammonium hydrogen sulphate (Bu4NHSO4) solutions with several molal concentrations (mBu4NHSO4 = 0.000, 0.005, 0.010, 0.015 and 0.020mol ⋅ kg‐1) of Bu4NHSO4 were determined at T = (298.15, 308.15 and 318.15)...
Retention of labile vitamins such as thiamine (vitamin B1) in NASA spaceflight foods intended for extended-duration missions is critical for the health of the crew. In this study, the degradation kinetics of thiamine in three NASA spaceflight foods (brown rice, split pea soup, BBQ beef brisket) ...
Treatment of tyrosine with paraformaldehyde and catalytic amounts of p-toluenesulfonic acid, at reflux in toluene, directly generates benzyl (S)-4-(4H-1,3-benzodioxin-6-ylmethyl)-5-oxo-1,3-oxazolane-3-carboxylate, which on treatment with boron trichloride in dichloromethane, affords (S)-4-hydrox...
The photolysis of 1,4-bis(2-phenyltetramethyldisilanyl)benzene (1) in the presence of isobutene in benzene gave 4-(isobutyldimethylsilyl)-1-(2-phenyltetramethyldisilanyl)-3-(dimethylphenylsilyl)benzene, 2-(isobutyldimethylsilyl)-1-{dimethyl[4-(2-phenyltetramethyldisilanyl)phenyl]silyl}benzene, a...
Stereochemical analyses of amino acids as well as their derivatives hold great importance. Owing to the increasing role of amino acid configuration in biomedical and pharmaceutical studies, numerous analytical methods have been described in the literature. Literature shows that time to time seve...
In this work, a series of novel indole-2-amide compounds were designed, synthesized, characterized and the anti-inflammatory activity in vivo were evaluated. Compounds 8a, 10b, 12h, and 12l exhibited marked anti-inflammatory activity in 2,4-Dinitrofluorobenzenethe (DNFB) - induced mice auricle e...
Fatty acids themselves have a number of biological properties and its easy intake by the human body will focus to the synthesis of many heterocyclic moiety substituted with fatty acid residue, to make more gradual intake of heterocycles in the human body. 2,5-Dimethyl pyrrole 2(a–e) and 1,3-ben...
Three microperoxidases – hemin-6(7)-gly-gly-his methyl ester (HGGH), mesohemin-6(7)-gly-gly-his methyl ester (MGGH) and deuterohemin-6(7)-gly-gly-his methyl ester (DGGH) – have been prepared as models for heme-containing peroxidases by condensation of glycyl-glycyl-l-histidine methyl ester wit...
