Three pigeons were trained on a differential, intradimensional autoshaped discrimination. A 45 degrees line tilt was always paired with food whereas a 15 degrees line tilt was never paired with food. All subjects learned the discrimination within 17 sessions. The pigeons were then given generalization tests in extinction over seven ...

1. Mature laying hens were subjected to ambient temperatures sufficient to maintain body temperature of 43 degrees C for periods of 6 to 7 h during the day (eight periods) or the night (five periods). This did not reduce total daily food consumption. 2. The effect of heat stress during ...

Folacin derivatives were found to vary greatly in thermal stability. It is worth mention that pteroylmonoglutamic acid (PGA), the folate used therapeutically and in food supplementation, was extremely stable to heat under the experimental conditions, that is, at 100 degrees C. in neutral solution. Under these conditions, 5-formyl-THFA also exhibited ...

The structure, distribution, density and innervation of arteriovenous anastomoses (AVAs) have been compared in the skin of Weddell and elephant seals, as part of a study of the structure and function of arteriovenous anastomoses in mammals. In both genera AVAs were coiled vessels with the segmental structure typical of "epithelioid" ...

A method for weighing samples of plaque using a weighing assembly comprising a sample-bearing boat, held in a closed capsule to avoid moisture loss to room or balance environment is described. The system described is an objective device for measuring, by wet weight the amounts of plaque accumulating under various ...

In this third paper on heat illness, the position of acclimatization in prevention of heat illness is reviewed. Both short and long-term acclimatization are considered, the former in more detail with discussion of present knowledge of the differences arising from artificial and natural acclimatization, the effects of training, water intake ...

The effect of chlorhexidine on the development of plaque, resulting from the inoculation with saliva of a tooth mounted in an artificial mouth, has been studied. The agent delayed the formation of plaque and also inhibited changes in pH and Eh, whether sucrose was present or not. Applied as a ...

Lysinoalanine, N6-(DL-2-amino-2-carboxyethyl)-L-lysine, an unusual amino acid implicated as a renal toxic factor in rats, has been found in proteins of home-cooked and commercial foods and ingredients. Although it has been reported to occur in both edible and nonfood proteins only after alkali treatment, it has now been identified in food ...

Heat-killed Pseudomonas aeruginosa are phagocytized much more slowly by human polymorphonuclear leukocytes than are the live organisms. The post-phagocytic increase in hexose monophosphate shunt activity (HMS) parallels the ingestion of the bacteria. The addition of serum to the live organisms causes a marked increase in both ingestion and cellular HMS ...

Sublethally stressed cells of 9 of 10 species of yeast were recovered at maximum levels when potato dextrose agar was adjusted to approximately pH 8. The optimum for candida utilis was at approximately pH 10. At pH 3.5, as commonly employed with media selective for yeasts and molds, recovery of ...

It has been shown in several experiments that the heat-labile, growth-promoting factor "V" found in the blood of animals does not diminish or disappear when the animals are kept on vitamine B-free diet. The titer of the "V" substance present in the blood of normal animals is undiminished in animals ...

At an ambient temperature of 25 degrees C, selective cooling of the area preoptica medialis to 24 degrees +/- 1 degrees C produced a significant decrease in food intake together with hyperthermia. Heating the same area to 43 degrees +/- 1 degrees C resulted in the opposite effects. At an ...

The nucleosides adenosine, guanosine, cytidine, uridine, and thymidine were each heated with inorganic phosphate. Nucleoside monophosphates were formed in appreciable yield. This result has a bearing on the hypothesis of chemical evolution.

Studies of microbial survival in simulated deep-space conditions have established that these conditions will not sterilize contaminated spacecraft. Likewise, data presented at this and previous meetings of COSPAR have shown that many terrestrial microbes, particularly anaerobic sporeformers, readily tolerate simulated Martian environments. Any spacecraft landing on Mars must have a ...

Brown adipose tissue has been shown to be a strongly thermogenic effector organ in homeothermic animals exposed to cold and in hibernators during cold-induced arousal from deep hibernation. Because of the anatomical distribution of brown fat and the utilization of vascular countercurrent heat exchange, this cold-induced thermogenic response protects the ...

The effects of sodium alginate on Staphyiococcus aureus 196 exposed to mild heating or to freezing at -21 C were studied. The addition of sodium alginate to a diluent appeared to confer some protection of viable cells during mild heating. The effect of the presence of sodium alginate in the ...

The heat content of copepods and other microcrustaceans and two species of algae in calories per gram varied from 4427 for immature crayfish to 5643 for the female Diaptomus siciloides. The algae, cladoceran, anostracan, conchostracan, and immature crayfish were all below 5000, whereas all the copepods were above 5300 (x ...

Bacillus licheniformis was isolated from spoiled cans of banana purée. The isolate proved to be a thermophilic gas former which causes soft swell in cans of nonacidic food. Thermal resistance of the spores was examined. Heat treatment for at least 90 to 100 sec at 230 F was found necessary ...
