Onion bulbs (Allium cepa L. cv. Hysam) were stored under regular atmosphere (RA: 21% O2/0.1% CO2) and controlled atmospheres (CA2/2: 2% O2/2% CO2; and CA2/8: 2% O2/8% CO2) with 80±3% relative humidity (RH) at 0.5±0.5 °C for 9 weeks. Total pyruvic acid content (PY), changes in S-alk(en)yl-l-cy...

SummaryThe intestine has direct contact with nutritional information. The mechanisms by which particular dietary molecules affect intestinal homeostasis are not fully understood. In this study, we identified S-adenosylmethionine (SAM), a universal methyl donor synthesized from dietary methionine...

A measurement system for cystathionine (Cysta) lanthionine (LT), and S-(2-aminoethyl)-l-cysteine (AEC), and reduced products of their ketimines, perhydro-1,4-thiazapine-3,5-dicarboxylic acid (PHTZDC), 1,4-thiomorpholine-3,5-dicarboxylic acid (TMDA) and 1,4-thiomorpholine-3-carboxylic acid (TMA) ...

Pulse-chase experiments with 35SO42− fed for 10 min to leaves of Allium cepa (onion), A. sativum (garlic) and 4 A. siculum showed that label appeared in γ-glutamyl peptides within 15 min, reached a maximum amount at 1 hr and had decreased by 6 hr. Label was not detected in free S-alk(en)yl-l-cy...

The absolute configuration of the naturally occurring amino acid (−)-S-(2-carboxypropyl)-L-cysteine has been determined by asymmetric synthesis.

Ionic liquid 1-methyl-3-(3-sulfopropyl)-imidazolium hydrogen sulfate ([C3SO3HMIM][HSO4]) was synthesized and characterized by infrared spectroscopy (IR), nuclear magnetic resonance (1H and 13C NMR) and ultraviolet-visible (UV-Vis) spectra. Its thermal stability was also examined by thermogravime...

Ammonia borane is a promising hydrogen storage material that liberates hydrogen by thermolysis at moderate temperatures, but it also presents major limitations for practical applications including a long induction time before the initiation of hydrogen release and a difficult regeneration. Previ...

In this study, the bamboo dissolution capability of six amino acid-based ionic liquids (AAILs) with two different cations, i.e. 1-ethyl-3-methylimidazolium (Emim) and Tetrabutylphosphonium (P4444) and three anions derived from amino acids were investigated by Conductor-like screening model for r...

A series of oligomeric poly(tetrabutylphosphonium styrenesulfonate)s (PSSP#, where # is the number of monomer units in the oligomer) were prepared from tetrabutylphosphonium styrenesulfonate (SSP) as a monomer for application as a draw solute in a forward osmosis (FO) system. Although the water ...

To develop the “hydrate thermal energy storage technology”, it is desired to reveal the mechanism of the thermophysical property manifestation on ionic semiclathrate hydrate. The influence of valence on thermophysical properties has not been investigated so far. In the present study, the phase...

The photophysical properties of 4-cyano-4′-butyloxybiphenyl (4COB) in diluted solytion at room temperature are reported. From this study it is clear that 4COB forms an I(ntramolecular) C(harge) T(ransfer) state. Furthermore, the influence of the temperature on the formation of the ICT state of ...

The composition, structure and rheological properties and metal ions interaction with Enterolobium contortisilliquum gum were investigated. This gum contains galactose, arabinose, rhamnose and glucuronic acid as main monosaccharide components. 13C nuclear magnetic resonance spectroscopy revealed...

Fluoresence probe techniques have been employed to monitor interactions of sodium carboxymethylamylose (NaCMA) with cationic and anionic surfactants in aqueous solution in both the absence and the presence of added salt. The changes of the I1I3 ratio of the fluorescence of pyrene in NaCMA soluti...

Zinc ash has been used as a zinc source for precipitation of zinc borates through leaching–purification–precipitation route. Zinc ash containing about 71% Zn, 0.6% Fe, 28% Cl−, 0.2% Pb, and traces other elements such as Cu, Cd, As etc. in ppm level were leached in sulfuric acid. The leach solu...

The standard mole enthalpy of formation is an essential feature of chemical compounds, which is critical for assessing the thermal effects of chemical reactions with their participation. In this paper, two pure phases of zinc borates, 2ZnO·2B2O3·3H2O and ZnB4O7, have been synthesized by hydrot...

Polychlorinated biphenyls (PCBs) are persistent organic pollutants associated with non-alcoholic fatty liver disease (NAFLD) in epidemiologic studies. The purpose of this study was to evaluate the hepatic effects of a PCB mixture, Aroclor 1260, whose composition mimics human bioaccumulation patt...

Three sediment cores from Lake Ontario, Lake Erie and Indiana Harbor Ship Canal were collected, segmented and analyzed for Aroclor and non-Aroclor polychlorinated biphenyl congeners (PCBs). PCBs associated with the commercially produced Aroclor mixtures 1248 and 1254 dominate the sediment signal...

Aroclor 1254 (A1254) is the most toxic commercial PCB mixture produced, primarily due to its relatively high concentrations of dioxin-like congeners. This study demonstrates a comparative evaluation of dechlorination of A1254 and PCB-118 by indigenous organohalide respiring bacteria enriched fro...

River sediment contamination is a critical environmental problem. Concentrations of certain hydrophobic organic compounds (HOCs) in sediments in Taiwan are ranked at the top in the world.
