BACKGROUND Modern anesthesiology has integrated the use of ultrasonography as a tool that has displaced neurostimulation as a technique for locating peripheral nerves. The aim of this study was to determine which procedure is more effective for guiding interscalene block for total shoulder arthroplasty. METHODS We carried out a comparative, prospective non-randomized study comprised of the gr...

Recombinant factor VIIa (rFVIIa) is registered for treatment of inhibitor-complicated haemophilia, and a once-daily prophylactic administration of rFVIIa is successful in reducing the number of bleeding events. This suggests that a single rFVIIa dose has a pro-haemostatic effect up to 24 hours (h), which is difficult to explain given its half-life of 2 h. In this study, six pigs received a 90 µ...

BACKGROUND Despite a possible role of Helicobacter pylori in gastric carcinoma (GC), its pathogenesis is not clear. There is scanty data on apoptosis in GC in relation to H. pylori and CagA antibody. Therefore, we studied gastric epithelial apoptosis in GC and non-ulcer dyspepsia (NUD) with or without H. pylori infection, and the degree of apoptosis in relation to CagA antibody status. METHOD...

INTRODUCTION AND OBJECTIVES The aim was to investigate etiologic and cardiovascular risk factors in obese children from Extremadura, Spain, and their relationship with insulin resistance and plasma adipocytokine levels. METHODS The study included 373 children (age, 3-13 years) who were randomly selected from schools in the city and province of Badajoz and from two health centers in the Spanis...

Brock, Robert W., Michael W. Carson, Kenneth A. Harris, and Richard F. Potter. Microcirculatory perfusion deficits are not essential for remote parenchymal injury within the liver. Am. J. Physiol. 277 (Gastrointest. Liver Physiol. 40): G55–G60, 1999.—A normotensive model of hindlimb ischemia-reperfusion in Wistar rats was used to test the hypothesis that microvascular perfusion deficits contrib...

The genus Hypericum is one of the most important medicinal plants that contain 17 species in Iran, three of them are endemics. This paper reports the essential oil composition of eight Hypericum species from Iran. The essential oil analysis of a number of the studied plants has already been reported but their report from Iran may be valuable for scientists.  Samples collected from different pla...

To compare the metabolic effects of elevated plasma concentrations of IGF-I and insulin, overnight-fasted normal subjects were studied twice, once receiving IGF-I and once insulin at doses that resulted in identical increases in glucose uptake during 8-h euglycemic clamping. Recombinant human IGF-I or insulin were infused in one group at high doses (30 micrograms/kg per h IGF-I or 0.23 nmol/kg ...

BACKGROUND Modified toluidine blue staining (MTBs) is a simple, inexpensive and time saving method to detect H. pylori in gastric biopsy specimens. As a metachromatic stain, it simultaneously highlights intestinal metaplasia, a gastric cancer precancerous lesion. The aim of this study was to assess the reliability of MTBs compared with hematoxylin-eosin (H and E) for H. pylori detection using i...
