Responses of glial cells to stress and glucocorticoids

Abstract

The rheological behavior of AOT/water dispersions over the whole two-phase concentration range (1.4 to 18.5 1 wt% AOT at 25°C) is reported here. At a concentration around 8 wt% AOT, the dispersions undergo a phase inversion from being water-continuous to being liquid crystalline-continuous. Below the phase inversion point the water-continuous dispersions are viscoelastic. At the phase inversion point there is a substantial reduction in viscosity and in relaxation times. Above the phase inversion point, the dispersions become more elastic and show increasing values of viscosity and relaxation time. Shear viscosities of water-continuous dispersions exhibit hysteresis in increasing-decreasing shear rate experiments. A shear thickening region was detected in the increasing shear mode, which may be associated with the formation of shear-induced structures similar to those found above the phase inversion point.

Material and Methods. The tool was translated into Spanish and a manual was created. The manual was submitted for authorization to the Ethics Committee of the National Public Health Institute of Mexico. The kit was sent to 122 units (response rate of 84.4%), covering a wide range of institutions in six contrasting states of Mexico according to the Human Development Index (HDI). The tool was validated internally and externally using statistical methods. Results. Differences were observed in the teams' research utilization capacity within each phase, regardless of their composition by gender, experience or academic level but with differences according to the extent of involvement in patient care and to the states' HDI. Conclusions. The tool was validated both internally and externally for its application under widely varying conditions in Mexico.

Rodriguez Noriega, E.",,"1999",,"Background: Enterococci have become one of the main causes of nosocomial infections. Enterococci are intrinsically resistant to various antimicrobial agents and can become multiple-drug resistant through the acquisition of resistance-encoding genes. The treatment of enterococcal infection including those caused by E. faecalis and E. faecium is extremely difficult. Objective: To analyze the susceptibility of clinical isolates of enterococci. Material and methods: The study was conducted at the Hospital Civil de Guadalajara, a university affiliated tertiary care center. All enterococcal strains isolated from clinical sites from 1991 to 1993, and from 1996 to June 1999 were included. A total of 681 strains were analyzed: 471 were E. faecalis and 210 E. faecium. Isolates were identified using microdilution method and all were tested for antimicrobial susceptibility using a microdilution method. Results: Resistance to ampicillin, rifampin, and vancomycin was stable during the period in E. faecalis. High-level resistance to aminoglycosides and resistance to ciprofloxacin increased in E. faecalis to 30 and 40%, respectively. E. faecium isolates demonstrated increasing high-level resistance to aminoglycosides, ampicillin and ciprofloxacin (37, 58, and 56%). Vancomycin resistance in E. faecium was noticed in 1999 isolates. Conclusions: The increasing resistance to most available antibiotics in E. faecalis and E. faecium represents a challenge.",,,,,,,,,"http://hdl.handle.net/20.500.12104/44220","http://www.scopus.com/inward/record.url?eid=2-s2.0-80052922353&partnerID=40&md5=8c4829f22a683b30e4b324ab264e5677",,,,,,"5",,"Enfermedades Infecciosas y Microbiologia",,"222

Luquin, S.",,"2010",,"A growing body of evidence suggests that glial cells are involved in practically all aspects of neural function. Glial cells regulate the homeostasis of the brain, influence the development of the nervous system, modulate synaptic activity, and carry out the immune response inside the brain. In addition, they play an important role in the restoration of the nervous system after damage, and they also participate in various neurodegenerative disorders. In a similar way, the importance of stress and glucocorticoids (GCs) on brain function is being increasingly recognized. Within the brain, stress hormones target both neurons and glial cells. Through their actions on these cells, glucocorticoids exert organizational functions on various processes of the developing brain and contribute to neuronal plasticity in the adult brain. Moreover, stress and glucocorticoids have become especially attractive in the study of a number of neurodegenerative disorders. However, studies on the mechanisms behind glucocorticoid-induced regulation of brain function have been classically focused on their effects on neurons. In this review, we start by describing the main functions of glial cells and then proceed to present data highlighting the effects of stress and GCs on brain function. We conclude the review by presenting recent evidence linking stress and glucocorticoids to glial cell function. " 2010 Bentham Science Publishers Ltd.
