introduction: previously, we demonstrated that i.p. injection of aqueous extract prepared from aerial parts of drosera spatulata (droseraceae) can induced remarkable analgesia in both phases of formalin test in rats. because, analgesia induced in acute phase of formalin test mainly mediated by activation of central analgesic mechanisms and also paragigantocellularis (pgi) nucleus is part of bra...

BACKGROUND It has long been recognized that analyzing the behaviour of the complex intracellular biological networks is important for breeding industrially useful microorganisms. However, because of the complexity of these biological networks, it is currently not possible to obtain all the desired microorganisms. In this study, we constructed a system for analyzing the effect of gene expression...

Understanding how climate change impacts natural systems requires investigations of the effects of environmental variation on vulnerable species and documentation of how populations respond to change. The willow beetle Chrysomela aeneicollis is ideal for such studies. It lives in California's Sierra Nevada on the southern edge of its worldwide range. Beetles experience elevated air temperatures...

Two forms of dermatan sulfate proteoglycans, called DS-PGI and DS-PGII, have been isolated from both bovine fetal skin and calf articular cartilage and characterized. The proteoglycans were isolated using either (a) molecular sieve chromatography under conditions where DS-PGI selectively self-associates or (b) chromatography on octyl-Sepharose, which separates DS-PGI from DS-PGII based on diffe...

background: currently, non-invasive methods for screening atrophic gastritis and gastric cancer are lacking. the purpose of this study was to evaluate the value of serological parameters including serum pepsinogen i (pgi), pepsinogen ii (pgii) and pepsinogen i: ii ratio for the screening atrophic gastritis and gastric cancer.   methods : the study population consisted of 132 dyspeptic patients ...

Inhalation of aerosolized prostacyclin (PGI(2)) exerts selective pulmonary vasodilation, but its effect is rapidly lost after termination of nebulization. Amplification of the vasodilatory response to inhaled PGI(2) might be achieved by phosphodiesterase (PDE) inhibitors to stabilize its second messenger, cAMP. We established stable pulmonary hypertension in perfused rabbit lungs by continuous ...

In obesity, skeletal muscle blood flow during exercise (functional hyperemia) is impaired. We have indirectly demonstrated that an altered arachidonic acid metabolism is responsible for the impaired functional vasodilation in the obese Zucker rat (OZR), a model of obesity. In this study, we tested the hypothesis that there is an impaired release of PGI(2) due to a nitration of PGI(2) synthase (...

OBJECTIVE In rehabilitation, treatment is individually tailored to each patient's goals. Individualized instruments allow patients to choose domains that they consider important, which may make them particularly appropriate as evaluative tools in this setting. We aimed to evaluate the psychometric properties of the Norwegian version of the patient generated index (PGI) in patients with rheumati...

AIM to find out biomarker as diagnostic tool of H. pylori chronic gastritis. METHODS the design of present study was a diagnostic test and there were 104 subjects with H. pylori chronic gastritis who fulfilled the inclusion and exclusion criteria. The diagnosis of H. pylori chronic gastritis was based on histopathological examination and PCR with ureC primer of the gastric biopsy specimen. In...
