Progress in Neurobiology | Year: 2016

In the last years there has been a considerable advance in the knowledge on the regulation of astrocytes by sex steroids under physiological and pathological conditions. By the activation of a variety of nuclear and membrane receptors, sex steroid hormones regulate the functions of astrocytes and their communication with other cell types in the central nervous system. Under physiological conditions astrocytes participate in the neuroendocrine and behavioral actions of gonadal steroids, as well as in the hormonal control of brain tissue homeostasis. Under pathological conditions astrocytes mediate, at least partially, the neuroprotective effects of gonadal steroid hormones; given that sex steroids modulate reactive astrogliosis and reduce the release of pro-inflammatory molecules by these cells. Given the side effects that sex steroids may have when administered systemically, a number of synthetic agonists of the receptors for gonadal steroid hormones in the nervous system have been developed, and may be considered for clinical use after brain injury as potential enhancers of the neuroprotective astrocytic functions. © 2016 Elsevier Ltd

Fluid Phase Equilibria | Year: 2013

This is the first part of a series of two communications in which a Helmholtz energy model is developed and applied to the prediction of thermodynamic properties of non-polar fluids and their mixtures. In this first part, the application is concerned only with pure non-polar fluids.The Helmholtz energy model is based on previous work by the author and co-workers in which the Helmholtz energy of the fluid is represented as a contribution of two terms: one is an extended corresponding states model and the other is a correction term. In the case of single components, this correcting term is a function of temperature and density.In this study 18 fluids were considered, namely: the normal alkanes from ethane to octane, isobutane, ethylene, cyclohexane, benzene, toluene, nitrogen, carbon dioxide, carbon monoxide, oxygen and argon. Percentage absolute average deviations (AADs) were calculated with the following results: 0.175 for pρT data; 0.279 for saturation pressures; 0.168 and 0.324 for saturated-liquid and saturated-vapour densities, respectively; 1.364 and 1.563 for isochoric and isobaric heat capacities, respectively, and 0.638 for speeds of sound. This performance is, by and large, quite comparable with the demanded accuracy of modern technical Helmholtz energy models for fluids of industrial interest and practical applications in process design and simulation. © 2013 Elsevier B.V.

This is the second part of a series of two communications in which a Helmholtz energy model is developed and applied to the prediction of thermodynamic properties of non-polar fluids and their mixtures. In this second part, the application is concerned only with mixtures of non-polar fluids.The Helmholtz energy model is based on previous work by the author and colleagues in which the Helmholtz energy of the fluid is represented as a contribution of two terms: one is an extended corresponding states model and the other is correction term. In the case of mixtures, this correcting term is mixing rule, in terms of local compositions, of a temperature- and density-dependent function. Local compositions are calculated with a coordination number model for square-well fluids.The mixtures that were considered were eight "primary" systems and 29 "secondary" systems of methane, ethane, propane, isobutane, n-butane, nitrogen, carbon dioxide, carbon monoxide, hydrogen and argon and a few ternary and quaternary systems. Percentage absolute average deviations (AADs) were calculated with the following results: 0.114 and 0.255 for pρT data of primary and secondary mixtures, respectively; 0.094 and 0.052 for pρT data of ternary and quaternary systems, respectively; 1.153 and 0.108 for isobaric heat capacities and speeds of sound of primary mixtures, respectively; 1.210 and 1.280 for bubble-point vapour pressures of primary and secondary mixtures, respectively; and absolute average deviations of 0.744cm3/mol and 288cm6/mol2 for second and third virial coefficients, respectively. This performance was found to be very satisfactory when compared with the expected accuracy of mixture Helmholtz energy models, i.e. that by Lemmon and Jacobsen, which is cited further ahead. © 2013 Elsevier B.V.

In this work a Helmholtz energy mixture model that had been previously published by the author was applied to natural gases and the related multicomponent systems. The Helmholtz energy of the mixture is the sum of two terms: one is an extended corresponding states model and the other is a correction term that is mixing rule, in terms of local compositions, of a temperature- and density-dependent function. Local compositions are calculated with a coordination number model for square-well fluids.The systems of interest were ternary, quaternary, multicomponent systems and natural gases. Deviations were calculated for pρT data, speeds of sound, isobaric heat capacities, isobaric and isenthalpic enthalpy differences, saturated-liquid densities of liquefied natural gases and vapour pressures of ternary systems. Representative percentage average absolute deviations were: 0.060 in pρT data of pipeline-quality natural gases; 0.099 in pρT data of unusual-composition natural gases; 0.249 in pρT data of rich natural gases; 0.220 in speeds of sound; 1.150 in isobaric heat capacities; 0.146 in saturated-liquid densities of liquefied natural gases and 1.267 in vapour pressures of ternary systems. Those results met the international standards of accuracy in the prediction of natural gas thermodynamic properties and were also comparable with those obtained with the GERG-2004 equation of state. © 2013 Elsevier B.V.

Porcine astrovirus (PAstV) has been poorly studied and has been associated mainly with gastroenteritis. Computational analysis has revealed the close relationship of PAstV with astroviruses of humans (HAstV) and cats (FAstV). In this study, 105 and 171 stool specimens were collected from piglets and children under 5 years of age, respectively, in different Colombian regions during a 1-year period. The stool samples were examined for astroviruses by ELISA and RT-PCR; 23.8% and 4% were found to be positive for PAstV and HAstV, respectively. Additional sequence analysis with partial sequences obtained from ORF2 identified at least 2 probable groups of PAstVs and possible recombination events between porcine and human astroviruses. This study provides preliminary evidence of the high presence of PAstVs in pigs and proposes the existence of multiple PAstV types that are evolutionarily closely related to HAstVs.

In this work a Helmholtz energy model is applied to the prediction of thermodynamic properties of air, the related binary mixtures and the intervening pure components. The Helmholtz energy of the mixture is represented as two contributions: one from a proven accurate extended corresponding states model and the other is a correction term. The corresponding states model relies on pure-component shape factors relative to nitrogen and extension to mixtures with the van der Waals one-fluid mixture model with ordinary combining rules. The correction term is temperature-, density- and composition-dependent with the use of a theoretically consistent local composition model with a coordination number model derived from lattice gas theory. For air the obtained average absolute deviations in densities were 0.090 per cent, 0.15 per cent in speeds of sound, 0.28 per cent in bubble-point pressures and 0.30 per cent for dew-point pressures. For the three associated binary mixtures, the absolute average deviations in densities were within 0.14 per cent and 0.63 per cent for bubble-point pressures. For oxygen and argon, the absolute average deviations were within 0.07 per cent in densities, 0.45 per cent in VLE properties and 0.012 per cent in speeds of sound. © 2009 Elsevier B.V.

This reflective article presents the current state of cardiopulmonary resuscitation (CPR) and reviews it from a bioethical standpoint. It starts with the ineffectiveness of CPR and the reasons why today it is a universally applied procedure, sometimes without taking into consideration the wishes or condition of the patient. Possible courses of action for the continuous improvement of cardiopulmonary resuscitation are proposed, especially from the humanistic point of view. Greater involvement of patients and their families in medical decisions, particularly in the planning of medical management rather than in the acute phase of the disease - as is the case for CPR - is encouraged. © 2014 Sociedad Colombiana de Anestesiología y Reanimación.

Surfactant therapy is effective in improving the outcome of very preterm infants. Trials have studied a wide variety of surfactant preparations used either to prevent or treat respiratory distress syndrome (RDS). In animal models, prophylactic surfactant leads to more homogeneous distribution and less evidence of lung damage. However, administration requires intubation and treatment of infants who will not go on to develop RDS. This is of particular concern with the advent of improved approaches to providing continuous distending pressure, particularly in the form of nasal continuous positive airway pressure (CPAP). To compare the effect of prophylactic surfactant administration to surfactant treatment of established RDS in very preterm infants at risk of RDS. We updated the search of the Cochrane Central Register of Controlled Trials (The Cochrane Library), MEDLINE, EMBASE, CINAHL, and clinical trials.gov register in December 13, 2011. Randomized and quasi-randomized controlled trials that compared the effects of prophylactic surfactant administration to surfactant treatment of established RDS in preterm infants at risk of RDS. Data regarding clinical outcomes were extracted from the reports of the clinical trials by the reviewers. Data analysis was done in accordance with the standards of the Cochrane Neonatal Review Group. Eleven studies were identified that met inclusion criteria [nine without routine application of continuous positive air way pressure (CPAP) in the selective treatment group; two with routine application of CPAP in the selective treatment group]The meta-analysis of studies conducted prior to the routine application of CPAP demonstrated a decrease in the risk of air leak and neonatal mortality associated with prophylactic administration of surfactant. However, the analyses of studies that allowed for routine stabilization on CPAP demonstrated a decrease in the risk of chronic lung disease or death in infants stabilized on CPAP. When all studies were evaluated together, the benefits of prophylactic surfactant could no longer be demonstrated. Although the early trials of prophylactic surfactant administration to infants judged to be at risk of developing RDS compared to selective use of surfactant in infants with established RDS demonstrated a decreased risk of air leak and mortality, recent large trials that reflect current practice (including greater utilization of maternal steroids and routine post delivery stabilization on CPAP) do not support these differences and demonstrate less risk of chronic lung disease or death when using early stabilization on CPAP with selective surfactant administration to infants requiring intubation.
