Resting and phorbol-activated human neutrophils were separated by treatment with Triton X-100 into detergent-extractable and cytoskeleton fractions. Respiratory burst oxidase activity was restricted entirely to the cytoskeleton. The cytoskeleton also contained approximately 15% of the neutrophil cytochrome b558, an oxidase-associated heme protein, as well as most of the oxidase-related cytosoli...
Paranodal axoglial junctions in myelinated nerve fibers are essential for efficient action potential conduction and ion channel clustering. We show here that, in the mature CNS, a fraction of the oligodendroglial 155 kDa isoform of neurofascin (NF-155), a major constituent of paranodal junctions, has key biochemical characteristics of a lipid raft-associated protein. However, despite its robust...
In this study, we examined human growth hormone (hGH)-induced changes in nonionic detergent solubility characteristics of its receptor (hGHR). Exposure of IM-9 cells to hGH caused a time- and concentration-dependent loss of immunoblottable detergent-extractable hGHRs and a corresponding accumulation of receptors in a detergent-insoluble pool. At 37°C, the loss of detergent-soluble and the accum...
the purpose of this study was to examine the comparative effect of story retelling and role playing on efl learners’ vocabulary learning and reading comprehension. to carry out the purpose of the study 90 female learners of tabarestan language school located in noshahr were non-randomly selected. they took pet test and among these 90 participants 62 students were selected as homogenous learners...
Activation of the stress response attenuates proinflammatory responses by suppressing cytokine-stimulated activation of the NF-kappaB signaling pathway. In this study, we show that the activation of the cellular stress response, either by heat shock treatment or after exposure to sodium arsenite, leads to a transient inhibition of IkappaBalpha phosphorylation. Inhibition of IkappaBalpha phospho...
In this experiment, we used 15 newborn Holstein male calves that their initial weight was 41 ± 4.5 kg and their age was one week. The experiment was conducted in a completely randomized design with three treatments and five replications. Treatments included: 1- control treatment without flaxseed, 2- treatment containing 5% flaxseed and 3- treatment containing10% flaxseed. Flaxseed replaced ...

This report was prepared by Dr. Jonathan Köhler, Department of Applied Economics University of Cambridge, UK, for the Centre Européen d'Etudes des Polyphosphates, the Western European phosphate industry's joint research association (a European Chemical Industry ...
Epidermal growth factor increases surface hydrophobicity and resistance to acid in the rat duodenum.
Epidermal growth factor (EGF) is produced in Brunner's glands and plays a role in healing and repair of duodenal ulcers. We examined the participation of zwitterionic phospholipids of mucus in the effects of EGF. Under anesthesia, groups of rats received an intraduodenal bolus of either saline or EGF. Some rats received subcutaneous indomethacin followed by EGF or EGF followed by a detergent (5...
