Proteins of the Tol-Pal (Tol-OprL) system play a key role in the maintenance of outer membrane integrity and cell morphology in gram-negative bacteria. Here we describe an additional role for this system in the transport of various carbon sources across the cytoplasmic membrane. Growth of Pseudomonas putida tol-oprL mutant strains in minimal medium with glycerol, fructose, or arginine was impai...

The aim of this research was to improve our understanding of human toxicity due to exposure to DMF, MEK, or TOL individually as compared to exposure to DMF-MEK or DMF-TOL mixtures, by comparing EC50 values as well as the morphological changes in HepG2 cells treated with these substances. We found that there was marked cell necrosis in the groups treated with mixtures than in those treated with ...

The objective of the present study was to develop a physiologically based pharmacokinetic (PBPK) model for a ternary mixture of alkyl benzenes [toluene (TOL), m-xylene (XYL), and ethylbenzene (EBZ)] in rats and humans. The approach involved the development of the mixture PBPK model in the rat and extrapolation to humans by substituting rat physiological parameters and blood:air partition coeffi...

in order to evaluate and drought tolerance selection in cowpea genotypes and to identify the best indices for drought tolerance, an experiment was conducted at research field university of tehran in karaj during 2011-2012 growing season. in this study, 31 cowpea genotypes were evaluated in a randomized complete block design (rcbd) with three replications under normal irrigation (non- stress) an...

for identifying drought tolerance genotypes 29 wheat genotypes as cultivar factor and irrigation and non irrigation treatments as an irrigation factor in a split block design with 3 blocks were planted at a research filed of college of agriculture, tehran university, iran. there was a low and non significant correlation (r=0.35) between yield at non irrigating (ys) and yield at irrigating (yp) ...

A study was performed in growing pigs to evaluate the efficacy of α-tocopherol (Tol) concentration in plasma, muscle, liver, and adipose tissue following dietary supplementation with vitamin E (VE) and various sources of fat. The trial involved 96 piglets weaned at an average of 28 d of age. Piglets were fed for 2 wk a semipurified diet not supplemented with VE. Piglets were then randomly assig...

Some executive tasks may require diverse abilities to solve, having implications for the comprehension of an individual’s performance. This study investigated the processes involved in the resolution of a complex test of executive function (EF): the Tower of London (ToL) task. One hundred twenty-four healthy teenagers, 11–14 years old (M = 12.5, SD = 1.14) participated in the study. They were t...

This investigation was carried out for genetic characterization and determination of drought tolerance ten Egyptian cultivars wheat (Triticum aestivum L.), namely Misr 1, 2, Gemmiza 9, 10, 11, 12, Shandawel Giza 168, 171, Sids 14. These were grown in two winter seasons: 2018/2019 2019/2020 at the experimental farm Fac. Agric., Suez Canal Univ., Ismailia, Egypt, under watering regimes: normal (1...
