the present research was conducted to estimate the dietary lysine (lys) requirement of growing female quail base on performance and carcass constitutes at 24 to 42 d of age. a dose-response diet mainly based on corn, corn gluten and soybean meal was used. lys content was minimized in dose-response diet (10 g/kg) while assuring the minimum levels of all other essential amino acids in a manner th...

Alternation in the strength of left ventricular contractions was noted relatively frequently in patients with acquired aortic stenosis, but not in patients with congenital aortic stenosis of similar severity. The product of left ventricular systolic pressure and heart rate, an index of the myocardial oxygen requirement, was significantly higher in those patients who exhibited persistent pulsus ...

Acquired pulmonary vein stenosis is a rare cardiac defect and diagnosis can often be challenging, as many cases present with refractory or prolonged oxygen requirement over the expected course. Comorbid conditions can cloud this diagnosis further. Prognosis is poor for most patients. We present a case of idiopathic acquired pulmonary vein stenosis and discuss diagnostics, treatment options, and...

A gene encoding a putative pyruvate decarboxylase (EC 4.1.1.1) was isolated from a genomic library of the filamentous fungus Aspergillus parasiticus strain SU-1. The deduced amino acid sequence showed 37% homology to PDC1 from Saccharomyces cerevisiae. Although A. parasiticus has an obligate growth requirement for oxygen, it produced ethanol in shake flask cultures indicating a response to anox...

There have been several reports on the utilization of oxygen during the cell life cycle (1-7), with particular emphasis on the question of whether there is any change during mitosis . One of the most elegant of these studies, the "Cartesian Diver" experiments of Holter and Zeuthen (1) on synchronous egg cells, indicated that the oxygen requirement was decreased in mitosis . While Scholander et ...

A computerized infusion system was used to determine mivacurium infusion requirements to maintain 95% and 50% neuromuscular block in 15 infants less than 1 yr of age. Neuromuscular block was measured by adductor pollicis EMG and anaesthesia maintained with 66% nitrous oxide in oxygen and alfentanil 50-100 micrograms kg-1 h-1. Neuromuscular block was produced by repeated bolus doses of mivacuriu...

A cause and effect understanding of thermal limitation and adaptation at various levels of biological organization is crucial in the elaboration of how the Antarctic climate has shaped the functional properties of extant Antarctic fauna. At the same time, this understanding requires an integrative view of how the various levels of biological organization may be intertwined. At all levels analys...

Most yeast species can ferment sugars to ethanol, but only a few can grow in the complete absence of oxygen. Oxygen availability might, therefore, be a key parameter in spoilage of food caused by fermentative yeasts. In this study, the oxygen requirement and regulation of alcoholic fermentation were studied in batch cultures of the spoilage yeast Zygosaccharomyces bailii at a constant pH, pH 3....

background low-cost anaerobic sequencing batch reactor (asbr), which is widely used for controlling high-organic wastewater, is an effective method to remove chemical oxygen demand (cod). objectives the main objectives was evaluating the feasibility of using asbr in the treatment of synthetic dairy wastewater, determining its removal efficiency, and assessing the effect of temperature on operat...

Bleomycin is an anti-neoplastic agent with potential for producing pulmonary toxicity, attributed in part to its freeradical-promoting ability. The central event in the development of toxicity is endothelial damage of the lung vasculature due to bleomycin-induced cytokines and free radicals, ultimately progressing to lung fibrosis. The treatment is discontinuation of bleomycin, initiation of sy...
