A world checklist of Onychophora (velvet worms), with notes on nomenclature and status of names.

Currently, the number of valid species of Onychophora is uncertain. To facilitate taxonomic work on this understudied animal group, we present an updated checklist for the two extant onychophoran subgroups, Peripatidae and Peripatopsidae, along with an assessment of the status of each species. According to our study, 82 species of Peripatidae and 115 species of Peripatopsidae have been described thus far.

The 2004 Australian prison entrants' blood-borne virus and risk behaviour survey.

Objectives: To assess the prevalence of blood-borne viruses and associated risk factors among prison entrants at seven Australian prisons across four States.

Design: Consecutive cross-sectional design. Voluntary confidential testing of all prison entrants for serological markers of human immunodeficiency virus (HIV), hepatitis C (HCV) and hepatitis B (HBV) over 14 consecutive days in May 2004.

Aging and food restriction alter some indices of bone metabolism in male rhesus monkeys (Macaca mulatta).

Food restriction increases life span, reduces aging rate and affects a wide variety of biological functions. In rats, food restriction delays bone growth and reduces bone density and mineral content. We report the effects of aging and long-term (> 6.

Diet restriction in rhesus monkeys lowers fasting and glucose-stimulated glucoregulatory end points.

Male rhesus monkeys (Macaca mulatta) of different age groups representing the species life span were fed ad libitum or a 30% reduced calorie diet over a 7-yr period. During the first 2-3 yr of this longitudinal study, glucose and insulin levels were not altered by diet restriction (DR). However, reductions in fasting blood glucose became apparent in DR animals after 3-4 yr.
