The chiral diphosphine ligand R,R-trans-1,2-C(6)H(10)(NHCOC(6)H(4)PPh(2))(2), 1, gives the fluxional trans-chelate complexes [M(1)]X, 2a-2c, M = Au or Ag. It is suggested that a similar trans-chelate conformation may be present in the catalytic intermediate [Pd(1)].

This study investigated the evolution of trans-9 trans-11 conjugated linoleic acid (CLA) from cis-9 trans-11 CLA during methylation and its avoidance through a rapid base methylation of milk fat. The study examined three conditions shown to result in loss of cis-9 trans-11 CLA during methylation namely: temperature, methylation time, water contamination in old reagents and acidic conditions. Th...

Epoxyeicosatrienoic acids (EETs) are vasodilator, natriuretic, and antiinflammatory lipid mediators. Both cis- and trans-EETs are stored in phospholipids and in red blood cells (RBCs) in the circulation; the maximal velocity (V(max)) of trans-EET hydrolysis by soluble epoxide hydrolase (sEH) is threefold that of cis-EETs. Because RBCs of the spontaneously hypertensive rat (SHR) exhibit increase...

Taste and odor (T&O) problems in drinking water frequently occur because of many compounds present in the water, of which trans-1,10-dimethyl-trans-9-decalol (geosmin) and 2-methylisoborneol (MIB) are well-known. In this study, a fast and effective method was established for simultaneous determination of 10 T&O compounds, including geosmin, MIB, 2,4,6-trichloroanisole (TCA), 2-methylbenzofuran,...

The trans-»eis photoisomerization of a series of substituted stilbazolium salts (A t X , At: trans-l-alkyl-4-[4-R-styryl]-pyridinium and -quinolinium, R = CN. H, CH3 and OCH3, X " = T and CIO4) was studied by laser flash photolysis and steady state irradiation measurements. The quantum yields of eis ^ trans photoisomerization (<£c_t and $ t _ c ) and of fluorescence of the trans isomers (f) ...

Two modern laser-based techniques were synchronously applied to study the dynamics of the trans-resveratrol activity in Botrytis cinerea-infected grapes. Direct analysis of trans-resveratrol in both infected and noninfected grapes (Vitis vinifera, Aledo variety) was performed by using an analytical technique incorporating laser desorption coupled with laser resonant ionization and time-of-fligh...

background: this study examined the applicability of trans-theoretical model (ttm) to understand exercise behavior among female college students in hamadan university of medical sciences, iran in 2007. methods: a cross-sectional descriptive study was conducted. the dependent variables analyzed were exercise efficacy expectation, decisional balance (pros and cons). the independent variable was s...

patients with syndrome x coronary disease represent a heterogeneous group of patients. medical treatment with dilators and calcium channel blockers are not very effective. we evaluated the use of transmyocardial laser revascularization (tmlr) in treating 5 patients with this syndrome. between may 2002 to december 2005, 5 patients with cardiac syndrome x (mean age of 49.7 years) underwent tmlr. ...
