The Measurement of Uptake of Nitrous Oxide by Pneumotachography. I. Apparatus, Methods and Accuracy.
A method of measuring the breath-by-breath uptake of nitrous oxide by the pulmonary capillary blood is described. With defined reservations, this uptake is given by the difference between the tidal volumes inspired and expired. The tidal volumes were measured by pneumotachography. The accuracy of these measurements is discussed. Precautions taken to reduce errors are described, with particular ...
It has recently been demonstrated in this laboratory (l-3) that “biologically labile” methyl groups can be oxidized to CO2 in the rat. This has been established by feeding methionine containing radioactive carbon in the methyl group and demonstrating the presence of radioactive CO2 in the expired air. In the present communication a comparison is made of the rates of oxidation of methyl groups a...
The objectives of the pilot study are to (1) confirm the general observation that an immune-supporting supplement, ASEATM, has an effect on athletic performance and (2) determine the specific physiological parameters: Heart Rates (HR), volume of O2 inspired (VO2), volume of CO2 expired (VCO2), volume of expired gas (VE), Respiration Rate (RR), Respiratory Exchange Ratio (RER), Aerobic Threshold...
The establishment of 3-hydroxyanthranilate (3-OHAA) as an intermediate in the conversion of tryptophan to niacin or its biological equivalent in Neurospora (1, 2) has led to findings (3-5) which indicate that this compound serves a similar role in animals. Much effort to establish the details of the individual reactions involved has centered around studies of the products of the oxidation of 3-...
Abstract The current study aimed to investigate the influence of expired hardened cement blended with ground granulated blast furnace slag on bond, microstructure, and durability high-strength concrete (HSC). Five mixes are prepared; first mix is taken as a control, remaining four used experimental blends. HSC characteristics evaluated by compressive, flexural, splitting tensile, tests. Further...
Amino acid requirements of sows may change from early to late gestation due to the accelerated growth of products of conception after d 70 of pregnancy. The objective of this study was to determine the Trp requirement, Phe kinetics, and energy expenditure in early (d 35 to 53) and late (d 92 to 111) pregnancy using the indicator amino acid oxidation method and indirect calorimetry. The same 6 s...
BACKGROUND Large amounts of expired and unused medications accumulate in households. This potentially exposes the public to hazards due to uncontrolled use of medications. Most of the expired or unused medications that accumulate in households (household medical waste) is thrown to the garbage or flushed down to the sewage, potentially contaminating waste-water, water resources and even drinkin...
In two previous articles we discussed how there are many misconceptions concerning time-sensitive chemicals and how time-sensitive chemicals should be managed. What remains to be discussed is ‘‘How does one treat and stabilize time-sensitive chemicals that have been stored for prolonged periods and have developed additional hazards?’’ That is the subject of this manuscript. (Note: For the purpo...
