Potassium chlorate is a powerful oxidizer salt that, when mixed with a fuel source, has been used as a homemade explosive (HME). As an inorganic salt, potassium chlorate has no appreciable vapor pressure under ambient conditions and requires temperatures exceeding 300 °C for decomposition. Howe...

This study aimed to investigate three different electrodialysis (ED) configurations using two distinct membranes, a monovalent ion selective membrane and a non-selective heterogeneous membrane. The configurations were evaluated in terms of efficiency of potassium recovery from vinasse and energy...

In this article we report results of combined theoretical and experimental NMR studies on muscimol, the bioactive alkaloid from fly agaric mushroom (Amanita muscaria). The assignment of 1H and 13C NMR spectra of muscimol in DMSO-d6 was supported by additional two-dimensional heteronuclear correl...

Pipoxolan has been reported to have antitumor activity. However, the effects of pipoxolan on lung cancer cell metastasis remains unclear. This study examined the anti-metastatic effects of pipoxolan on lung adenocarcinoma cancer cells (i.e. CL1–5, CL1–0, and A549) and its underlying molecular ...

The molecular structures of tert-butyldimethylsilanol and its hemihydrate in the gas phase have been determined by electron diffraction. The two diffraction patterns are indistinguishable, indicating that the hydrate is essentially completely dissociated in the vapour phase under the conditions ...

The research was aimed at defining the impact of non-enzymatic glycosylation of pea globulin 7S on its biological properties. Glycation of pea globulin 7S was carried out at the temperature of 37 °C for 7 days and at 60 °C for 3 days. No glycation of the of the pea globulin 7S was observed whe...

Protein content and globulin subunit composition of soybean seeds affect the quality of soy foods. In this proteomic study, the protein profile of soybean seeds with high (∼45.5%) or low (∼38.6%) protein content and with or without the glycinin (11S) subunit 11SA4 was examined. 44 unique prote...

The effects of selenium (Se) on the protein content, amino acid profile, secondary structure and subunit composition of soy proteins and its distribution were evaluated, as was the effect of peroxyl radicals produced by thermal decomposition of AAPH on the conformational changes of Se-enriched β...

A comparison between theory and experiment, concerning the K(4 s) + K(7s)→K(4 s) + K(5f) reaction of excitation energy transfer in thermal collisions, is presented. The cross sections for this process are calculated for the potassium vapour temperatures in the range of 310–1000 K. The calculat...

7S protein is one of four major storage proteins in soybean. The present study compared the relative cholesterol-lowering activity of the 7S protein with that of total soybean protein isolate (SPI). Forty-eight hamsters were divided into six groups fed non-cholesterol diet or one of five high-ch...

BackgroundPulmonary hypertension (PH) causes right ventricular dysfunction and central venous congestion, and may lead to congestive hepatopathy. The serum 7S domain of collagen type IV (P4NP 7S) is an established marker of liver fibrosis in chronic liver disease. We aimed to determine whether P...

ObjectiveStreptococcus mutans is a principal bacterium that forms pathogenic biofilm involved in the development of dental caries. S. mutans possesses a quorum sensing system (QS) stimulated by competence stimulating peptide (CSP), which is associated with bacteriocin production, genetic compete...

The reaction of phenyl(bromodichloromethyl)mercury-derived dichlorocarbene with bis(trimethylsilyl)mercury in benzene at 80° gave as principal products trimethyl(trichlorovinyl)silane, trimethylchlorosilane, metallic mercury and phenylmercuric bromide. An analogous reaction with bis(trimethylge...

Four new (chloromethyl)disilanes, (ClCH2)Cl2SiSiCl2Me (I), (Cl2CH)Cl2SiSiCl2Me(II), (ClCH2)MeClSiSiClMe2(III) and (ClCH2)Me2SiSiCl3(IV), have been prepared and studied as to their attitude toward intramolecular rearrangement with aluminum chloride. The reactivity decreases in the order: (III) > ...

2-Substituted 1,2-dihydropyridines including an optically active one were regioselectively prepared from 2-substituted piperidines through three intermediates, that is, (a) 1,2,3,4-tetrahydropyridines, (b) 5-bromo-6-methoxypiperidines, and (c) 1,2,3,6-tetrahydro- 6-methoxypyridines.

Previous studies have established that epicutaneous application of 5-methyl-3-n-pentadecylcatechol (5-Me-PDC), a synthetic analog of a poison ivy urushiol component, leads to immune tolerance to 3-n-pentadecylcatechol (PDC) in mice. The induction of tolerance by 5-Me-PDC may be mediated by a pro...

Three-component coupling reactions of 2-(cyanomethyl)phenol, aryl halides, and carbon monoxide (CO) in orthogonal–tandem catalysis were investigated. In the reactions, 2-(cyanomethyl)phenyl esters, which are produced through Pd(PPh3)4-catalyzed alkoxycarbonylation of aryl halides with 2-(cyanom...

Nanometer layers are grafted on the surface of carbon or metallic electrodes by electrochemical reduction of iodo or bromoacetonitrile in acetonitrile. The structure of these layers, (carbon or metal)–[CH2–CH(NH2)–]n, is determined by electrochemistry, ellipsometry and IRRAS. The bond between...

The diphosphate moiety of geranylgeranyldiphosphate (GGdP) was replaced with metabolically and hydrolytically stable analogous polar portions, in an attempt to obtain new geranylgeranyltransferase (GGTase) inhibitors, which could also be selective over congener enzyme farnesyltransferase (FTase)...

In the continuing study directed toward the development of peroxisome proliferator-activated receptor gamma (hPPARγ) agonist, we attempted to improve the water solubility of our previously developed hPPARγ-selective agonist 3, which is insufficiently soluble for practical use, by employing two...
