The molecular mechanisms of laser-induced changes in the cell structure and function are not well known. The authors examined the effects of low-power laser irradiation on unnucleated pig blood platelets. The obtained results showed that laser irradiation (1-5 J) caused in blood platelets lipid peroxidation (measured as thiobarbituric acid reactive substances) and superoxide anion generation, c...

In the title compound, C(32)H(33)NO(6)S, the indole ring system makes dihedral angles of 62.78 (10) and 80.53 (8)°, respectively, with the phenyl and benzene rings. In the crystal, the mol-ecules are linked through inter-molecular C-H⋯O hydrogen bonds, forming a chain along the a axis. Between the chains, a weak aromatic π-π stacking inter-action [centroid-centroid distance = 3.831 (2) Å] is ob...

The synthesis of the racemic a-glycerophosphoric acid (1) and of the I( -)-cr-glycerophosphoric acid (2) has been reported. The Z( -)-CL-glycerophosphoric acid has been isolated from various natural sources, such as phosphatides, and as an intermediate product of fermentation or glycolysis. For this reason, in a previous paper we called the I( -)-cr-glycerophosphoric acid the “biological” acid....

1. The effect of in vitro glycation on delta-aminolevulinic dehydratase (ALA-D) under several experimental conditions was investigated. When preincubated with 500 mM glucose at 37 degrees C for 20 hr, ALA-D was 80% inactivated and glycated hemoglobin levels were increased more than fourfold. 2. Thiobarbituric acid species were not modified during glycation; therefore ALA-D inactivation cannot b...

The asymmetric unit of the title compound, C(17)H(25)NO(7)S, contains two independent mol-ecules, which are enanti-omers forming a hydrogen-bonded dimer associated with two R(2) (2)(7) patterns. In each mol-ecule, one ethyl group from the two available ethyl ester functional groups is disordered. In one mol-ecule, the ethyl group of the ester function from an α-carb-oxy-lic acid is positionally...

the present work was carried out to study the effect of vacuum packaging and pomegranate peel extract (pe) treatments on the quality of pacific white shrimp (peneous vannamei) during refrigerated storage. changes in ph, thiobarbituric acid (tba), total volatile base nitrogen (tvb-n), trimethylamine (tma), aerobic plate counts, psychrophilic, lactic acid bacteria and enterobacteriaceae counts, m...
