The dose-dependent induction of unscheduled DNA synthesis (UDS) by 2-acetylaminofluorene (AAF) and N-OH-2-acetylaminofluorene (N-OH AAF) in primary rat hepatocytes isolated from untreated and 3-methylcholanthrene (3-MC) treated rats was investigated. 3-MC treatment was not necessary for the dose-dependent induction of UDS induced by N-OH AAF, suggesting the(More)
BACKGROUND There has been a worldwide increased prevalence of tuberculosis (TB) in recent years, with a similar trend observed in Jamaica and more recently in children admitted to the University Hospital of the West Indies, Jamaica. Data regarding paediatric TB, especially as it relates to all aspects of HIV co-infection, are needed from developing(More)
Widespread male body size variation in P. latipinna appears to be attributable to genetic variation in the size at maturation. The contribution of adult growth needs to be assessed because adult growth rates may vary with size at maturation and local environment. In our laboratory study we examined adult growth patterns as a function of size at maturation(More)
We investigated the potential effect of social interactions between juveniles on the adult body size and male sexual behavior of the live-bearing teleostPoecilia latipinna, the sailfin molly. Contrary to expectation, juveniles exhibited very low levels of aggression. Juvenile growth rates did not differ between fish raised alone and fish raised in pairs(More)

The aim of the following experiments is to identify and to describe those factors most probably important in determining reproductive success in male Girardinus metallicus and to investigate how competition among juveniles affects these characters. The quantitative relationships among male size, male aggressiveness, and male sexual activity are examined.(More)
