Abstract The 3D flow filling process of LOX (Liquid Oxygen) dome is studied in a liquid oxygen/methane rocket engine. volume, field pressure and velocity distributions oxygen at different time are determined. property propellant the injection characteristic obtained. results show that when has not been filled, state disorder, flows around annular wall middle dome. static near equalizing orifice...

DescriPtion oF the eviDence collection methoD A critical analysis of articles from the MEDLINE database was carried out using the following keywords (MeSH terms): asthma, asthma/epidemiology, asthma/therapy, oxygen therapy, prednisone, prednisolone, dexamethasone, mineralocorticoids, glucocorticoids, adrenal cortex hormones, bronchodilators, albuterol, terbutaline, fenoterol, salmeterol, formot...

Vasoactive drugs are normally utilized to elevate mean artery pressure and maintain adequate organ perfusion in clinical treatment. During the injection, morphological changes and the subsequent oxygen supply alteration in the brain, e.g., possible hypoxia, are prone to introduce serious damage and even dysfunction to the brain. Therefore, multiparameter monitoring of cerebral microvasculature ...

The effects of S-allylcysteine on oxidative damage and spatial learning and memory deficits produced by an intrahippocampal injection of amyloid-beta peptide 25-35 (Abeta(25-35)) in rats were investigated. The formation of reactive oxygen species, lipid peroxidation and the activities of the antioxidant enzymes superoxide dismutase and glutathione peroxidase were all measured in hippocampus 120...

Suspensions of an oxygen-sensitive (MT-7) and of an oxygen-insensitive(M109) tumor cell line were injected i.v. into BALB/c mice. Exposure to 100% O2 after injection of the cells did not modify the initial arrest of either cell line in the lung. Exposure of animals given injections of MT-7 cells for 60 h to 100% oxygen decreased the number of lung colonies formed even when onset of oxygen expos...

Suspensions of an oxygen-sensitive (MT-7) and of an oxygen-insensi tive (M109) tumor cell line were injected i.v. into BALB/c mice. Exposure to 100% O2 after injection of the cells did not modify the initial arrest of either cell line in the lung. Exposure of animals given injections of M I7 cells for 60 h to 100% oxygen decreased the number of lung colonies formed even when onset of oxygen exp...

Hyperbaric oxygen exposures were evaluated for treatment of progressive liver abscesses produced by intraperitoneal injection of combined cultures of Fusobacterium necrophorum plus either Bacteroides fragilis subsp. fragilis or Fusobacterium nucleatum in a mouse model. Infected control and hyperbaric oxygen-exposed mice were autopsied 5 or 6 weeks after inoculation of bacteria and were assigned...
