Isobaric vapor–liquid equilibrium for ternary mixtures of ethanol and methylcyclohexane with 3-methylpentane and tert-butyl alcohol at 101.3kPa
2007
Abstract Consistent vapor–liquid equilibrium (VLE) data for the ternary systems 3-methylpentane + ethanol + methylcyclohexane and ethanol + tert-butyl alcohol (TBA) + methylcyclohexane are reported at 101.3 kPa. The VLE data have been correlated by Wilson, UNIQUAC and NRTL equations. The ternary systems do not present azeotrope and are well predicted from binary interaction parameters.
Epidemiology of Nonalcoholic Fatty Liver Disease and Nonalcoholic Steatohepatitis: Implications for Liver Transplantation.
2018
Nonalcoholic fatty liver disease (NAFLD) affects 25% of the global adult population with a range of 13.5% in Africa and 31.8% in the Middle East. Nonalcoholic fatty liver disease is closely associated with a constellation of metabolic comorbidities which include: obesity, type 2 diabetes mellitus, hypertension, and hypercholesteremia. In fact, the increasing number of metabolic comorbidities not only increases the prevalence of NAFLD but also places patients at higher risk for progressive liver disease. As such, NAFLD is presently among the top etiologies for hepatocellular carcinoma and an indication for liver transplantation (LT) in the United States. Therefore, the following recommendati…
IL28B and PNPLA3 Polymorphisms Affect Histological Liver Damage in Patients with Non-alcoholic Fatty Liver Disease.
2012
Background & Aims: Genetic background may affect liver damage in patients with non-alcoholic fatty liver disease (NAFLD). The main outcomes of the study were to assess whether IL28B rs12979860 and rs8099917 polymorphisms, together with PNPLA3 rs738409 C>G polymorphism, are associated with lobular inflammation and fibrosis, in NAFLD patients. Methods: One hundred sixty consecutive NAFLD patients were assessed by liver biopsy (Kleiner score); anthropometric, and biochemical and metabolic features were included. IL28B rs12979860 C>T, IL28B rs8099917 G>C, and PNPLA3 rs738409 C>G single nucleotide polymorphisms were tested. Results: Seventy-four (46.2%) patients had IL28B rs12979860 CC polymorph…
Predictors of weekly alcohol drinking and alcoholrelated problems in binge-drinking undergraduates
2015
Texto en inglés e español Las importantes implicaciones que genera el consumo intensivo de alcohol entre los jóvenes justifican el interés por determinar qué factores predicen su aparición. Concretamente, en este estudio se analiza el papel de la personalidad y edad de inicio en el consumo de alcohol en la predicción del consumo semanal de alcohol, y de todas estas variables en la predicción del número de consecuencias asociadas al consumo en jóvenes universitarios. Se evalúan 213 consumidores intensivos de primer curso de la Universidad Complutense de Madrid. Todos ellos cumplimentaron un autoregistro de consumo, el BIS-11, el NEO-FFI y el IECI de consecuencias asociadas a la ingesta. Los …
Urgencias en alcoholismo: abordaje desde los centros de tratamiento de adicciones
2007
La presentación de situaciones de urgencia en los dispositivos de tratamiento de adicciones constituye una realidad relativamente frecuente.Aunque el papel del médico en el tratamiento de los trastornos adictivos se centra en intervenciones de desintoxicación y deshabituación, deberá contemplar la actuación en estas situaciones. Actuación que estará condicionada por las características del dispositivo asistencial en el que desarrolle su labor y que dependerá de los recursos disponibles y posibilidades de interconsulta.La intervención estará dirigida a prevenir-evitar la presentación de urgencias, identificarlas precozmente si ocurren, tratar lo tratable en situación de seguridad y proceder …
Uztvertā vecāku pārraudzība, smēķēšanas un/ vai alkohola lietošanas biežums pusaudžiem no pilnām un nepilnām ģimenēm.
2018
Pētījuma mērķis bija izpētīt sakarības starp uztverto vecāku pārraudzību un alkohola lietošanas biežumu pusaudžiem no pilnām un nepilnām ģimenēm. Datu ievākšanai tika izmantota Vecāku uzraudzības aptauja ( Parental Monitoring Scale, Stattin & Kerr, 2009), kas sastāv no 24 jautājumiem, kas atspoguļo vecāku uzraudzības veidus., (t.i., ko vecāki zina, pusaudžu atklātība, kontroles sajūta, vecāku kontrole). Apgalvojumi tiek vērtēti pēc Likerta skalas 5 punktu sistēmā (1- „nekad”, 5- „vienmēr”). Un alkohola lietošanas biežuma aptauja (Youth risk behavior survey. Division of adolescent and school health, CDC, 1993.g.). Attiecīgā aptauja sastāv no 5 jautājumiem. Respondentiem tiek lūgts izvērtēt k…
Tipologías de consumidores de alcohol dentro de la práctica del botellón en tres ciudades españolas
2010
In this work, 6,009 youngsters (14-25 years old) who practice the «botellon» were interviewed in three cities of the Valencian Community. After a stratifi ed sampling among college and noncollege students, a two-step cluster analysis was carried out for each sample with two aims: to identify different types of alcohol consumers in the practice of the «botellon» and to carry out a crossed validation of the results obtained. The variables included in the analysis were the following: gender, age group (university students: U; adolescent students: ES), performance of intensive episodes of consumption (yes/no), number of years practicing the «botellon» and grams of alcohol ingested. The results …
Organic solvent vapor effects on phase transition of α and β tegafur upon grinding with solvent additives.
2012
Abstract Solvent effects on α tegafur (5-fluoro-1-(tetrahydro-2-furyl)uracil) phase transition to β tegafur during grinding with solvent additive, as well as phase transition in samples exposed to 95% relative solvent vapor pressure has been studied in this research. Samples containing 0.5% and 0.1% of β tegafur in α and β tegafur mixture, as well as samples of pure α tegafur were ground with different solvent additives, and conversion degrees depending on the solvent were determined using PXRD method. Samples with α and β tegafur weight fraction of 1:1 were exposed to 95% relative solvent vapor pressure, and phase transition rates were determined. Solubility of α tegafur, solvent sorption …
Vaporization and autoignition characteristics of ethanol and 1-propanol droplets : influence of water
2013
Detailed investigation of the vaporization of an isolated of ethanol and 1-propanol droplet was carried out in this experimental study. The experimental set-up consists of a heated chamber with a cross quartz fibers configuration as droplet support. An alcohol droplet is located at the intersection of the cross quartz fibre with a controlled initial diameter (300-600µm). Ambient temperature is varied from 298 to 973K at atmospheric pressure. The quasi-steady theory has been used to compare and to explain all experimental results. The real impact of the water concentration on the vaporization rate of an ethanol droplet is also examined, where two ‘quasi-steady’ periods are observed on the d2…
Phosphatidylinositol phosphate kinase type I gamma regulates dynamics of large dense-core vesicle fusion.
2005
Phosphatidylinositol-4,5-bisphosphate was proposed to be an important regulator of large dense-core vesicle exocytosis from neuroendocrine tissues. Here, we have examined the kinetics of secretion in chromaffin cells from mice lacking phosphatidylinositol phosphate kinase type Iγ, the major neuronal phosphatidylinositol-4-phosphate 5-kinase. Absence of this enzyme caused a reduction of the readily releasable vesicle pool and its refilling rate, with a small increase in morphologically docked vesicles, indicating a defect in vesicle priming. Furthermore, amperometry revealed a delay in fusion pore expansion. These results provide direct genetic evidence for a key role of phosphatidylinositol…
