Altered polymorphonuclear leukocyte (PMN) function is thought to contribute to organ dysfunction during the systemic inflammatory response syndrome (SIRS). To test this hypothesis, we evaluated whole blood PMN function adherent to fibronectin or laminin in patients with mild or severe acute pancreatitis as a paradigm for sirs. Whole-blood PMN intracellular H2O2 production, expression of CD32w (...

Drought stress is one of the most important factors limiting the survival and growth of plants in the different habitats of Iran. Detailed knowledge about the ecophysiological responses of native plants to drought stress could contribute to the success of breeding and re-vegetation programs. Six wild populations of Anthemis tinctoria, were assigned to four drought treatments, i.e. well...

During the highly pathogenic avian influenza (HPAI) H7N7 virus outbreak in The Netherlands in 2003, 88 infected persons suffered from mild illnesses, and 1 died of pneumonia. Here, we studied which of the 14 amino acid substitutions observed between the fatal case (FC) virus and a conjunctivitis case (CC) virus determined the differences in virus pathogenicity. In virus-attachment experiments, ...

Background: Occupational stress has physical and psychological consequences, and is a major cause of job dissatisfaction among employees, which can reduce the quality of services provided. This study was conducted to examine the relationship between job stress and the prevalence of musculoskeletal disorders (MSDs) among computer users in hospitals (private & governmental) of Gorgan, Iran, in 20...

Despite the positive effects of mild hypothermic conditions on monoclonal antibody (mAb) productivity (qmAb ) during mammalian cell culture, the impact of reduced culture temperature on mAb Fc-glycosylation and the mechanism behind changes in the glycan composition are not fully established. The lack of knowledge about the regulation of dynamic intracellular processes under mild hypothermia res...

This study was carried out to determine the consequence of foliar application agmatine (0 and 0.5 mM), on growth, physiological biochemical traits, yield turnip (Brassica rapa L.) plants grown under water stress or salt conditions. The effect three irrigation regimes (100%, 80% 40% field capacity) concentrations (0, 100 200 mM NaCl) in pots greenhouse conditions were studied. Water deficit deve...

abstract in order to evaluate the effects of drought stress and defoliation on sunflower, a study was conducted under controlled conditions. treatments were a combination of three levels of drought ((100, 60 and 30 percent of field capacity (fc)) and three levels of defoliation (control, removal of either 4 or 6 leaves from lower part of the plant) laid out, in a completely randomized design wi...
