Prostaglandins (PGs) are lipid molecules that profoundly affect cellular processes including inflammation and immune response. Pathways contributing to PG output are highly regulated in antigen-presenting cells such as macrophages and monocytes, which produce large quantities of these molecules upon activation. In this report, we demonstrate aberrant(More)

The brains of 21 rhesus monkeys inoculated with SIVMAC251 were examined after intervals ranging from 3 to 27 months and compared with five uninoculated controls. Eighteen animals became infected and individually exhibited several distinct patterns of disease. Nine (50%) had largely intramural leptomeningeal venous infiltrates (LMVI) without multinucleate(More)
There is strong evidence that patients with AIDS have loss of cortical neurons. In this study we have examined the hippocampus of rhesus monkeys infected with simian immunodeficiency virus (SIV) to determine whether neuronal damage occurs in this model of human AIDS and to investigate its time course. Twenty-eight infected monkeys (23 young [< 9 years] and(More)
Readers of Mathematical Spectrum have recently indicated an interest in the problem of expressing a natural number was a sum of (at least two) consecutive natural numbers (see [1]-[5]). Bob Bertuello showed that this is not possible when n is a power of 2. We prove here a general result which determines those natural numbers that can be expressed as a sum(More)
This is a retrospective study of 38 cases of infection by Babesia macropus, associated with a syndrome of anaemia and debility in hand-reared or free-ranging juvenile eastern grey kangaroos (Macropus giganteus) from coastal New South Wales and south-eastern Queensland between 1995 and 2013. Infection with B. macropus is recorded for the first time in agile(More)
A 10-month-old female, Wire-haired Pointing Griffon dog had a hamartoma of the hypothalamus. Episodes of sudden flaccid collapse had increased in frequency and duration for 7 months. Cerebrospinal fluid pressure was normal. A flat, pedunculated mass, 2.5 X 3.0 X 0.9 cm, covered the brain stem between the pituitary gland and pons. Its 1.2-cm-diameter(More)
