1. Autophagy protects against neural cell death induced by piperidine alkaloids present in Prosopis juliflora (Mesquite)
ABSTRACT Prosopis juliflora is a shrub that has been used to feed animals and humans. However, a synergistic action of piperidine alkaloids has been suggested to be responsible for neurotoxic damage observed in animals. We investigated the involvement of programmed cell death (PCD) and autophagy on the mechanism of cell death induced by a total extract (TAE)

2. Multipotent male germline stem cells (mGSCs) from neonate porcine testis
ABSTRACT Spermatogonial stem cells (SSCs) are the foundation of spermatogenesis, during which unlimited spermatozoa is produced daily derived from SSCs in the testis throughout life of the male. Germline stem (GS) cells can be isolated from spermatogonia, which shared the characteristics of SSCs and embryonic stem cells (ESCs), and can be passaged stably in

3. Atividade enzimática dos subtipos de fosfolipase A2 (PLA2) em cultura primária de neurônios / Activity of phospholipase A2 (PLA2) subtypes in primary cultures of rat cortical neurons
The phospholipase (PLA2) is considered a key enzyme in the metabolism of phospholipids, which are the main constitutes of cellular membranes. Alterations in PLA2 activity have been reported in the brain and blood cells of psychiatric patients and also in biological matrixes like rat brain tissues and cultures of neuron cells. Inhibition of PLA2 activity in p

4. Efeitos das células de schwann cultivadas e tratadas com o pedf no trofismo de neurônios medulares cultivados e na recuperação motora de ratos submetidos ao trauma contuso da medula espinal pelo impactor / Effect of the cells of Schwann cultivated and treated with the PEDF in the trophism to spinal cord neurons cultivated and in the motor recovery of rats submitted to the trauma contused of the spinal cords for the Impactor
The present study aimed the assessment of the trophic and regenerative potential of the Schwann cells (SC) and of the neurotrophic factor PEDF on the spinal cord neurons by means of cultures of those cells in vitro as well as in an experimental model of a contused spinal cord lesion in vivo. SC were cultivated from sciatic nerves fragments of young adult rat

5. Astrócitos e harmônio da tireóide (T3): desenvolvimento neuronal e neuroproteção
Thyroid hormone (T3) has a significant influence on the development and maturation of the mammalian SNC. T3 modulates neuronal development in an astrocyte-mediated manner, secreting soluble factors and other molecules, as ECM proteins, and regulating neurite outgrowth, neuron proliferation and migration. Astrocytes also participate actively in the neuronal m

6. Ultrastructural description of rabies virus infection in cultured sensory neurons
Primary cultures were made from adult mouse spinal ganglia for depicting an ultrastructural description of rabies virus (RABV) infection in adult mouse sensory neuron cultures; they were infected with rabies virus for 24, 36, and 48 h. The monolayers were processed for transmission electron microscopy and immunochemistry studies at the end of each period. As

7. "Efeito modulatório da nicotina sobre a neurotransmissão em núcleos encefálicos responsáveis pelo controle cardiovascular em ratos geneticamente hipertensos e normotensos" / "Nicotine modulatory effects on neurotransmiter systems in the cardiovascular brain areas of spontaneously hypertensive and normotensive rats"
Nicotine is one of the most important agents for cardiovascular diseases in tobacco smoking. This alkaloid acts in the blood stream, but it also crosses the blood-brain-barrier and participate in the regulation of pivotal neurotransmitter systems for the blood pressure control and, eventually, for hypertension development. In this context, nicotine abuse cou

8. Formation of cholinergic synapses between dissociated sympathetic neurons and skeletal myotubes of the rat in cell culture.
Sympathetic principal neurons, dissociated from superior cervical ganglia of newborn rats, were plated into cultures containing rat skeletal myotubes formed from previously plated primary myoblasts. Electrophysiological evidence is presented that the neurons developed cholinergic synapses with the myotubes. In addition, the neurons developed cholinergic syna

9. Readily releasable pool size changes associated with long term depression
We have estimated, for hippocampal neurons in culture, the size of the autaptic readily releasable pool before and after stimulation of the sort that produces culture long term depression (LTD). This stimulation protocol causes a decrease in the pool size that is proportional to the depression of synaptic currents. To determine if depression in this system i

10. Ontogeny of electrically excitable cells in cultured olfactory epithelium.
A primary system has been developed in which it is possible to study the production of electrically excitable neuron-like cells from a precursor population of olfactory epithelial cells. Rat nasal epithelium was dissociated and placed in culture. The initial surviving cells are flat and ciliated and contain glial fibrillary acidic protein (GFAP). After 3-5 d

11. Sympathetic neuron density differentially regulates transmitter phenotypic expression in culture.
The effects of cell density and aggregation on expression of transmitter traits were examined in dissociated, pure sympathetic neuron cultures, grown in fully defined, serum-free medium. After 1 week at a density of 7-8 X 10(3) neurons per 35-mm dish, moderate levels of tyrosine hydroxylase (tyrosine 3-monooxygenase, EC 1.14.16.2) activity and substance P we

12. Secretion of neuron-specific enolase, prolactin, growth hormone, luteinising hormone and follicle stimulating hormone by "functionless" and endocrine-active pituitary tumours in vitro.
Secretion of the neuroendocrine marker neuron-specific enolase by 24 pituitary tumours was measured in maintenance tissue culture. Eleven endocrine-active and 13 "functionless" tumours were defined by measurement of prolactin, growth hormone, luteinising hormone (LH) and follicle stimulating hormone (FSH) secretion rates in vitro and the corresponding plasma
