Predicting the biodegradation products of perfluorinated chemicals using CATABOL.

Perfluorinated chemicals (PFCs) form a special category of organofluorine compounds with particularly useful and unique properties. Their large use over the past decades increased the interest in the study of their environmental fate. Fluorocarbons may have direct or indirect environmental impact through the products of their decomposition in the environment.

The cayo santiago primate colony.

This is an account of the vicissitudes of the monkeys on Cayo Santiago. In it is described the relationship of the establishment of that primate colony to the development of the National Regional Primate Research Center Program in the United States and the Laboratory of Perinatal Physiology in Puerto Rico. The Cayo Santiago colony opened new aspects of biomedical research and stimulated the general use of nonhuman primates in behavioral as well as physiological investigations.

Progressive suppression of adrenocorticotropin secretion in resting adrenalectomized dogs by low stepwise infusions of cortisol.

Ten male mongrel dogs of 8.3-14.3 kg were bilaterally adrenalectomized and maintained on replacement steroids for 1 week.

Developmental behaviors: delayed appearance in monkeys asphyxiated at birth.

Development behaviors: delayed appearance in monkeys asphyxiated at birth.

Developmental behaviors were studied in monkeys subjected to asphyxia at birth. Visual depth perception, visual pla ing, and locomotion appeared significantly later than in nonasphyxiated monkeys. After these behaviors had been established in asphyxiates, however, there was little difference from those observed in normal monkeys.

Cerebral hemorrhage in relation to birth asphyxia.

The brains of monke guinea pigs asphyxiated at birth pletely resuscitated, and killed a ous times thereafter revealed no chial hemorrhages. However, postnatal distress and other factoring to a moribund state occurro brains revealed petechial hemor.
