Carbapenem-resistant Acinetobacter baumannii is increasing in prevalence. Polymyxin B and tigecycline are among the most active antibiotics used against this pathogen in vitro. Past in vitro studies, however, neglected the importance of simulating exposures observed in humans to determine their antibacterial effects. In this study, four carbapenem-resistant A. baumannii isolates were evaluated ...

To stimulate plant development in phytoremediation or the cultivation of non-food crops potentially contaminated soils, a biotechnologically created product could be applied. The aim this study was to explore possibility creation biofertiliser, based on activated sludge combined with bacterial strain detoxifying and growth promoting properties. presented is focused effect phenol following conce...

Chronic Helicobacter pylori disease is reduced with Allium vegetable intake. This study was designed to assess the in vivo anti-H. pylori potential of a variety of garlic substances. The garlic materials all showed substantial but widely differing anti-H. pylori effects against all strains and isolates tested. The MICs (range, 8 to 32 microg/ml) and minimum bactericidal concentrations (MBCs) (r...

The aim of the present study was to evaluate the effects of the level of salt intake on endothelium-derived factors in a group of patients with essential hypertension. A group of 50 patients with essential hypertension who had never been treated for the condition were placed on a low-sodium (50 mmol/day), low-nitrate (400 micromol/day) diet, which was supplemented, in a single-blind fashion, wi...

in this study, we investigated the effect of savory (satureja hortensis) essential oil, garlic(allium sativum) powder, and garlic aqueous extract on fungal load of poultry feed. tothis end, savory essential oil and garlic aqueous extract each amounting 62.5, 125, and250 μl/ml and mg/ml, respectively, per kilogram of feed and garlic powder amounting2.5, 5, and 10 g/kg of feed were used. one and ...

Experiments were carried out to study the effects of ammonia and nitrite on food consumption Macrobrachium amazonicum postlarvae. Postlarvae (average weight 0.0625 g) exposed during 21 days four concentrations total (0, 1.05, 2.1 4.2 mg. NH3+NH4+ L-1) 0.075, 0.15 0.30 mg N-NO2- L-1). After exposure period, six prawns per treatment maintained individually in 250 mL experimental units analyze as ...

The toughness of a polymer glass is determined by the interplay of yielding, strain softening, and strain hardening. Molecular-dynamics simulations of a typical polymer glass, atactic polystyrene, under the influence of active deformation have been carried out to enlighten these processes. It is observed that the dominant interaction for the yield peak is of interchain nature and for the strain...
