statement of the problem: reducing the patients' stress can prevent, or at least, limit the increase in blood glucose level. purpose: the study compares the effect of propofol and midazolam on blood glucose level in the patients undergoing dental implant surgery. the effect of pre-operational stress on blood glucose level during the surgery is also evaluated. materials and method: this prospect...

introduction roselle (hibiscus sabdariffa l.) as a medicinal plant belongs to the malvacea family. their active ingredient increases under water stress. humic acid bacteria derived from humus and other natural resources have hormonal effects and can improve nutrient absorption to enhance performance especially under stress conditions . materials and methods this experiment was conducted in the ...

background and aims. there are many edentulous people with severely resorbed residual ridges and non-resilient lining mucosa that are unable to tolerate occlusal forces during functional and parafunctional movements. lining the tissue surface of dentures with a flexible material can theoretically distribute and absorb forces with cushioning effect. the aim of this study was to evaluate the effe...

rice plants are injured at the seedling stage in early spring in northern iran. in order to study rice response to cold stress, the expression of osdreb1a, osap37, osmyb3r-2, and osnac6 genes encoding transcription factors was observed in 14-day-old seedlings of cold-tolerant genotype pr and cold-sensitive cv. hashemi during cold stress (5°c for 24 h) using the differential display method and t...

understanding the physiological processes associated with drought stress lead to an understanding of the basic mechanisms of resistance, maintaining yield potential and contribute to the identification of drought tolerant cultivars. for this purpose, the effects of drought stress in cowpea genotypes was evaluated using five different genotypes with different yield potential in a pot experiment ...

Background: Although all jobs can be stressful, occupational stress is an important issue in jobs that deal with human health. Evidence indicates that nursing is a stressful occupation. Objective: This research evaluated factors affecting occupational stress and strategies for coping with it. Methods: This cross-sectional descriptiv...
