When spinach thylakoids were subjected to moderate heat stress (40 degrees C for 30 min), oxygen evolution was inhibited, and cleavage of the reaction center-binding protein D1 of photosystem II took place, producing 23-kDa N-terminal fragments. The D1 cleavage was greatly facilitated by the addition of 0.15 mM ZnCl2 and 1 mM ATP and was completely inhibited by 1 mM EDTA, indicating the partici...

In this study, double loop electrochemical potentiokinetic reactivation (DLEPR) test was applied to determine the degree of sensitization in 316L type stainless steel, where obtained results were correlated with revealed microstructures after oxalic acid test and weight loss measurements of Streicher and Huey acid tests. Best agreement was provided with test parameters which are 1 M H2SO4 and 0...

the kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-6 (l) through a bulk liquid membrane is studied experimentally and theoretically. the proposed model is based on the assumption of a pure diffusion of the complex salt [k·l]+scn¯ through the liquid membrane stagnant films at the interfaces. it illustrates the connection between liquid-liquid extraction equilib...

Thiocyanate (SCN?) present in irrigation water can have negative effects on plant growth and crop yields. Addition of regulators (PGRs) alleviate toxic stress to plants. In the current study, we established a grey situation decision-making model (GSDM) integrate data RT-qPCR analysis for screening optimal addition PGRs minimise pollution stress. The (i.e., jasmonic acid [JA], indole-3-acetic [I...

iMany reports have been published on the effect of inorganic salts, especially LiBr, on the secondary structure of protein and synthetic polypeptide. Harrington and Scheilman (1) worked with solutions of silk fibroin, serum albumin, clupein, and ribonuclease and deduced that LiBr increases the stability of intramolecular hydrogen bonds. Perlmann (2) observed the change in dispersion constant, X...

L-Alanine transport was studied in plasma-membrane vesicles from rat liver. A gradient of NaSCN, but not of KSCN, stimulated alanine uptake. Monensin plus carbonyl cyanide p-trifluoromethoxyphenylhydrazone abolished the observed overshoot in uptake. After equilibration of alanine, NaSCN induced uphill transport.

nutritional standards and improve public health. The mission of KSCN is to develop and extend knowledge of clinical nutrition of all species, to promote education and training of dietitians in clinical practice, to facilitate contact among investigators in nutrition, medicine and related fields of interest, and to advocate for clinical nutrition research and its application to the clinical nutr...
