BACKGROUND Recently, some articles about patient-prosthesis mismatch (PPM) of the mitral valve have been published. However, the outcome of PPM of the mitral valve remains controversial. The objective of this study was to determine the impact of mitral valve PPM on clinical results after mitral valve replacement (MVR). METHODS AND RESULTS Eighty-four patients underwent MVR from 1992 to 2005. ...
Hypersecretion and chronic phlegm are major symptoms of chronic obstructive pulmonary disease (COPD) but animal models of COPD with a defined functional hypersecretion have not been established so far. To identify an animal model of combined morphological signs of airway inflammation and functional hypersecretion, rats were continuously exposed to different levels of sulfur dioxide (SO2, 5 ppm,...
To examine the effects of using synthetic Fischer-Tropsch (FT) diesel fuel in a modern compression ignition engine, experiments were conducted on a MY 2002 Cummins 5.9 L diesel engine outfitted with high pressure, common rail fuel injection, a variable geometry turbo charger, cooled EGR and a fully configurable engine management computer. Additionally, the effect of varied injection timing and ...
Objective(s): There is a rising use of gold nanoparticles (AuNPs) in goods and in the medical fields but there is concern about the toxicity of them. So in this study spherical AuNPs with 3 different concentrations were applied for investigating their effects in vivo. Materials and Methods: 40 male albino mice were randomly divided into sham, control, 25 ppm, 50 ppm, 100 ppm groups and were...
Physiologically based Pharmacokinetic Modeling of Metabolic Interactions Between nHexane and Toluene in Humans: Xiaozhong YU, et al. Department of Occupational and Environmental Health, Nagoya University Graduate School of Medicine—Some animal experiments have shown that mutual metabolic inhibition takes place between nhexane and toluene, but we have found only one report dealing with their met...
Ion homeostasis plays important roles in development of metabolic diseases. In the present study, we examined the contents and distributions of 25 ions in chicken muscles following treatment with selenium (Se) deficiency for 25 days. The results revealed that in chicken muscles, the top ranked microelements were silicon (Si), iron (Fe), zinc (Zn), aluminum (Al), copper (Cu) and boron (B), showi...
Offset pulse position modulation (OPPM) and Dicode (DiPPM) have been introduced as new attractive techniques, however, they are suffering from erasure, wrong slot, false alarm errors. in this paper, two types of error correction (EC) codes, Low-Density Parity Check (LDPC) code Reed Solomon (RS) code, where paired the OPPM DiPPM systems to reduce bugs, analyze best EC parameters, choose superlat...
We investigated the effects of dietary zinc deficiency on oxidative stress and bone metabolism. Four-week-old male Wistar rats were randomly assigned to one of three groups for 4 weeks: a zinc-adequate group (30 ppm); a zinc-deficient group (1 ppm); and a pair-fed group (30 ppm) that was pair-fed to the zinc-deficient group. The iron content and the thiobarbituric acid reactive substance level ...
An experiment involving 25 experiment stations in the North Central and Southern regions (NCR-42 and S-288, respectively) was conducted to assess the degree of uniformity of diet mixing among stations and to assess the variability among station laboratories in chemical analysis of mixed diets. A fortified corn-soybean meal diet was mixed at each station using a common diet formula (except for v...
Petroleum hydrocarbons had affected site soils at three separate locations over the estimated area of approximately 32,000 sq. ft. The depth of contamination varied from 3 feet in two areas to over 20 ft. in the area next to the retaining wall. Total Petroleum Hydrocarbon (TPH) concentrations ranged from less than 50 ppm up to 11,000 ppm with levels varying from the surface to the groundwater t...
