A monoclonal antibody, Py, was produced by immunizing mice with a glycoprotein fraction isolated from 3-week-old rat hippocampus. Py antibodies gave strong immunocytochemical staining of the perikarya and dendrites of large neurons in many areas of the rat brain, including the cerebral cortex, hippocampus, cerebellum, brain stem, and olfactory bulb.(More)
Encapsulation of antibiotics may improve treatment of intracellular infections by prolonging antibiotic release and improving antibiotic uptake into cells. In this study, liposome-encapsulated ciprofloxacin for inhalation (CFI) was evaluated as a postexposure therapeutic for the treatment of Coxiella burnetii, the causative agent of Q fever. Intranasal(More)
Explants of Embryonic Day 18 (E18) rat entorhinal cortex were cocultured with Postnatal Day 6 mouse hippocampal slices to study CNS regeneration in vitro. The present report describes a double-labeling paradigm for quantitative analysis of the type of new growth seen in immature cultures. Entorhinal projection neurons in living static cocultures were(More)
The development of the gamma-aminobutyrate (GABA)-ergic system in the human cerebral cortex and cerebellum was studied in post mortem specimens, by estimating the activity of glutamate decarboxylase (GAD) and the binding capacity for muscimol as markers of GABA-ergic nerve terminals and GABA receptors respectively. The age periods studied were as follows(More)
Benzodiazepine receptor binding and the concentration of the free tissue GABA, glutamate, glutamine, aspartate, and 13 other amino acids were estimated in specimens of cerebral cortex and cerebellum taken from normal foetuses and from perinatal and postnatal infants and adults postmortem. Compared with the ontogenetic increase, previously reported, in(More)
We determined the effects of voluntary wheel running on the hypothalamic-pituitary-adrenal (HPA) axis, and the peripheral determinants of glucocorticoids action, in male Zucker diabetic fatty (ZDF) rats. Six-week-old euglycemic ZDF rats were divided into Basal, Sedentary, and Exercise groups (n = 8-9 per group). Basal animals were immediately killed,(More)
Xin is a muscle-specific actin binding protein of which its role and regulation within skeletal muscle is not well understood. Here we demonstrate that Xin mRNA is robustly upregulated (>16-fold) within 12 h of skeletal muscle injury and is localized to the muscle satellite cell population. RT-PCR confirmed the expression pattern of Xin during regeneration,(More)
We have used the species-specific monoclonal antibodies OM1 and OM4 to identify the histiotypic pattern of projection from late embryonic rat entorhinal explants to the outer molecular layer of the dentate gyrus in organotypic cultures of 6-day postnatal mouse hippocampal slices. The presence of this entorhinal projection was detectable with the(More)
The effect of thyroid status on noradrenergic synaptic function in the mature rat brain was examined by measuring presynaptic alpha 2- and post-synaptic beta-adrenoceptors. Repeated triiodothyronine (T3) administration to rats (100 micrograms/kg X 14 days: hyperthyroid) caused an 18% increase in striatal beta-adrenoceptors as shown by [3H]-dihydroalprenolol(More)
In growing towards their hippocampal targets, incoming afferent axons from the entorhinal cortex arrive at the subicular pole of the hippocampus and normally turn pialwards from the alvear path, crossing (perforating) the subiculum and field CA1, but never the more distally situated field CA3. To address the question of whether a specific repulsive(More)
