In the last several years there have been impressive strides in the ability to explore the nature of hippocampal system functioning in humans by employing functional neuroimaging methods, permitting such methods to be used in conjunction with neuropsychological methods to better understand the role of the hippocampal system in memory. In this paper, we(More)
Mice account for over 80% of all animals used in experimentation. This study investigated how different housing conditions affected stress levels by measuring both corticosterone levels, using non-invasive faecal collection, and behaviour. Sixty outbred MF1 male mice were used which were separated into five different housing conditions at the beginning of(More)
This review summarizes evidence that supports working hypotheses for the roles of boron in animal model systems. It is well established that vascular plants, diatoms, and some species of marine algal flagellates have acquired an absolute requirement for boron, although the primary role of boron in plants remains unknown. Recent research findings suggest(More)
Three experiments were conducted to test the behavior of the offspring of rat dams (ZD) fed a mildly zinc deficient diet (10.0 micrograms Zn/g) during pregnancy and lactation. Since zinc deficiency causes anorexia, a second group of rat dams (PF) was fed the same quantity of the diet during gestation and lactation as was consumed by their ZD mates. A third(More)
BACKGROUND In view of the almost certain mortality of the acquired immune deficiency syndrome (AIDS) patient, controversy may arise as to how to treat those individuals with concomitant aneurysmal disease. METHODS We conducted a retrospective case review of six patients seen in a 1-year period, who had a history of either being positive for human(More)
BACKGROUND Aneurysmal subarachnoid hemorrhage is uncommon in the pediatric and adolescent age groups. Collagenopathies, particularly of collagen type III and IV, have been recognized in the pathogenesis of intracranial (i.c.) aneurysms in recent studies of cerebrovascular immunoreactivity and the molecular architecture of the walls of cerebral blood(More)
The hippocampal formation (HF) is involved in higher brain functions including learning and declarative memory. The possibility that dietary copper has a role in the morphological development, and therefore the function of the HF, has received little attention. A rat model of tiered copper deficiency, initiated during gestation, was employed to determine(More)
The impact of human immunodeficiency virus (HIV) on the clinical presentations, causative organisms, and neurologic outcomes of patients with spinal infections is reviewed. Thirty-two patients with spinal epidural abscesses, vertebral osteomyelitis, or both were treated at an urban hospital over a 42-month period. Thirteen of these patients were confirmed(More)
We report the case of a previously healthy woman who had an extremely rapid progression of pyogenic vertebral osteomyelitis. The plain film radiographs from 1 month before admission, from the time of admission, and from her 1 year follow-up are presented. Although it is a well known fact that pyogenic vertebral osteomyelitis can evolve rapidly and that the(More)
