Noradrenergic control of circadian rhythms in Cebus albifrons

American Journal of Physical Anthropology, 1973
AbstractManifestation of biologic oscillations (e.g., body temperature 24‐hour wave form) is the summation of the exogenous and endogenous response mechanisms of the biologic clock. Biologic rhythm asynchrony results from a rapid change in the environment presented to the time sensors.

Megaloblastic anemia and the requirement for folic acid in the cebus monkey (Cebus albifrons)

American Journal of Primatology, 1982
AbstractTo study the development of folic acid deficiency, nine 3‐year‐old cebus monkeys (Cebus albifrons) were fed purified diets containing varying amounts of added folic acid. Monkeys fed the diet without added vitamin stopped growing and then lost weight.

Synchronized retinal afterdischarge and neural dark adaptation in the monkey (Cebus albifrons)

Experimental Neurology, 1968
Abstract The relationship between the duration of synchronized after-discharge (30/sec), recorded from the optic chiasm of monkeys following cessation of illumination, and the intensity and duration of an immediately preceding test light; intensity and duration of prior conditioning illumination; duration of dark adaptation between conditioning and ...

Tool use in wild capuchin monkeys (Cebus albifrons trinitatis)

American Journal of Primatology, 1998
White-fronted capuchins were observed to use leaves as cups to retrieve water from tree cavities. On multiple occasions several individuals performed this behavior. Thus, these capuchins engage in habitual tool use, as defined by McGrew's classificatory scheme of tool using behavior.

Papillary Carcinoma of Apocrine Sweat Glands in a Capuchin Monkey (Cebus albifrons)

Journal of Medical Primatology, 1976
A tumor removed from the skin of the right pectoral region of a 19-year-old male Capuchin monkey (Cebus albifrons) was morphologically classified as a papillary carcinoma of apocrine sweat gland origin. The designation of malignancy was based primarily on cellular pleomorphism and stromal invasion.

Assessment of the Efficiency of Nitrogen Utilization in the Infant Cebus Monkey (Cebus albifrons) by Nitrogen Balance

Journal of Medical Primatology, 1986
Nitrogen (N) balance and growth were utilized to assess the efficiency of N utilization in the infant cebus monkey (Cebus albifrons). The efficiency of N utilization as calculated from N balance data was 35%. The efficiency of N utilization for growth was 37% as determined by weight change over a 28‐day trial and by body composition data from the ...
