The clinical and serological features have been analysed retrospectively in 42 patients with an onset of systemic lupus erythematosus (SLE) up to 16 years of age. Thirty-seven (88.1%) were female and 5 (11.9%) male. The mean age of onset was 12.3 years (range 7-16); 11 patients were 10 years or under. The mean duration of disease from diagnosis was 7.1(More)
Hair has been shown to archive a uniquely time averaged signal of endocrine activity, and holds attractive advantages for both laboratory and field research. Prior research has explored the potential of hair hormone analysis to examine hormone-behavior relationships. To date, no research has focused on the potential of the technique to investigate(More)
Studies of growth regulation and cellular transformation will be assisted by the identification of proteins that are preferentially synthesized in dividing cells. The 'proliferating cell nuclear antigen' ( PCNA ), distinguished by its apparent association with cell division, is defined by reaction with an antibody found in the autoimmune disease systemic(More)
In autoimmune disorders such as rheumatoid arthritis and systemic lupus erythematosus (SLE), autoantibodies are generated against a variety of macromolecules. Myositis is a human autoimmune disease characterized by weakness and wasting of muscle. In American studies, antibodies directed against soluble cellular constituents were detected by immunodiffusion(More)
The sera of six patients with autoimmune disease, predominantly myositis with pulmonary fibrosis, contain antibodies of the PL-12 specificity. These autoantibodies react with both protein and RNA components of human cells. The protein has a subunit molecular mass of 110 kD, and the RNA comprises a group of bands in the tRNA size class. Aminoacylation(More)
An autoantibody known as PL-7 was found in the serum of four patients with myositis and one with a systemic lupus erythematosus-like syndrome. The PL-7 antigen is an 80,000 dalton polypeptide that coprecipitates with transfer RNA. In aminoacylation reactions, PL-7 IgG inhibited the charging of tRNA with threonine but had little or no effect on charging with(More)
COURSE DESCRIPTION. Why do we behave the way we do? How have we come to be this way? How much of our behavior can be understood as a result of 'nature', 'nurture', or both? This course addresses these questions from environmental, biological, and evolutionary perspectives. We will examine human behavior in a comparative context, drawing on our understanding(More)
Male olive (Papio anubis) and hamadryas (P. hamadryas) baboons have distinctive sociobehavioral and physical characteristics. In the Awash National Park, Ethiopia, a hybrid population at the contact zone between these two species, exhibits heterogeneous sociobehavioral and physical characteristics. The ambiguity of the hybrid social environment and(More)
This study tests the "adaptive onset" hypothesis (AOH) proposed by Kuhle and explores the potential adaptive origins of menopause (Kuhle (2007) [3]). The AOH posits that both menopause and the timing of its onset are adaptive, and that age at onset may be mediated according to the likelihood of successful continued reproduction. Twelve factors were(More)
Vervet monkeys (Chlorocebus aethiops) often live in close proximity to humans. Vervets are known to raid crops, homes and gardens in suburban areas leading to human–vervet conflict. In general, primate groups with access to human foods experience increased population densities and intra-group aggression. This suggests high stress loads for vervets living in(More)
