Modified brucella broth medium was used to study the growth of Helicobacter pylori at varied pHs and partial pressures of oxygen and to determine the effect of urea on culture pH. Our findings suggested that the pHs of the media remained stable with or without urea and that H. pylori showed facultative acidophilism and obligate microaerophilism.

We examine whether a high wage–high employee intrapreneurial inputs model remains significant feature of the Russian economy. do so by estimating evolution ‘intrapreneurial’ contributions to companies in Russia, 1994–2015, using Akerlof's theory ‘partial gift exchange’. Akerlof (1982) suggests that discretionary organizational capacities rise when pay exceeds perceptions ‘fair’ comparable emplo...

Few studies have examined the adaptive significance of reversible acclimation responses. The aerobic performance and mating behaviour of the sexually coercive male eastern mosquito fish (Gambusia holbrooki) offers an excellent model system for testing the benefits of reversible acclimation responses to mating success. We exposed male mosquito fish to normoxic or hypoxic conditions for 4 weeks a...

Experiments were conducted to determine the water solubility of alkali basalts from Etna, Stromboli and Vesuvius volcanoes, Italy. The basaltic melts were equilibrated at 1,200°C with pure water, under oxidized conditions, and at pressures ranging from 163 to 3,842 bars. Our results show that at pressures above 1 kbar, alkali basalts dissolve more water than typical mid-ocean ridge basalts (MOR...

Investigations into the blood oxygenation level-dependent (BOLD) functional MRI signal have used respiratory challenges with the aim of probing cerebrovascular physiology. Such challenges have altered the inspired partial pressures of either carbon dioxide or oxygen, typically to a fixed and constant level (fixed inspired challenge (FIC)). The resulting end-tidal gas partial pressures then depe...

STUDY A lipid emulsion containing 10 percent medium-chain triglycerides (MCT) and 10 percent long-chain triglycerides (LCT) was infused at a rate of 1 ml/kg/h (3.3 mg/kg/min) for 2 h, in 12 patients (2 males, 10 females; mean age, 54 +/- 3 (SEM) years; range, 34 to 67 years) 24 h after open-heart surgery (mitral valve replacement). METHODS Hemodynamic factors (pulmonary and radial artery indw...

This article considers the role of SENCo during Covid-19 pandemic conditions school lockdown with partial reopening for children classified as ‘vulnerable’. It is argued that existing pressures and tensions already experienced by SENCos – example, related to time, workload, status, their prescribed managerial strategic have been highlighted conditions. Pressures resulting specifically from are ...

The pathogenesis of mucoinfective lung disease in cystic fibrosis (CF) patients likely involves poor mucus clearance. A recent model of mucus clearance predicts that mucus flow depends on the relative mucin concentration of the mucus layer compared with that of the periciliary layer; however, mucin concentrations have been difficult to measure in CF secretions. Here, we have shown that the conc...

Most current photosynthesis models, and interpretations of many wholeleaf CO(2) gas exchange measurements, are based on the often unstated assumption that the partial pressure of CO(2) is nearly uniform throughout the airspaces of the leaf mesophyll. Here we present measurements of CO(2) gradients across amphistomatous leaves allowed to assimilate CO(2) through only one surface, thus simulating...
