Asociación entre relaciones románticas y la calidad de sueño percibida por jóvenes universitarios

Introducción: Uno de los aspectos con mayor variación durante la adolescencia es el sueño, el cual se ve afectado por factores biológicos así como por los estados afectivos y emocionales. En esta etapa, los individuos establecen sus primeras relaciones sentimentales románticas, vínculos esenciales para la maduración de las relaciones sociales y psicosexuales. Este trabajo busca determinar la asociación existente entre las relaciones sentimentales románticas y sus características, con la calidad sueño percibida por los jóvenes. Metodología: Estudio realizado en una población de 1794 estudiantes de ciencias de la salud entre los 18 y 25 años de edad en Bogotá, Colombia, entre 2012 y 2013. Se obtuvo una muestra probabilística con asignación proporcional de 443 sujetos, estratificada por programa académico y sexo. Utilizando dos cuestionarios de auto reporte se exploraron las características de las relaciones sentimentales y la calidad de sueño percibida. Resultados: El 64% (IC 95%: 59,4-68,9%) de la población estudiada se encontró en una relación sentimental romántica. Estos sujetos tuvieron latencias de sueño prolongadas con menor frecuencia que quienes no tenían en una relación (p <0,05). La calidad de sueño percibida se asoció al nivel de satisfacción que tuvieron los sujetos en su relación, así como la atracción por su pareja. Rasgos obsesivos, ansiosos, temerosos y evitativos en la relación disminuyeron la calidad de sueño percibida. Conclusión: Las relaciones sentimentales románticas y sus características se asocian con la calidad de sueño percibida por los individuos. Se requieren estudios que determinen causalidad en esta asociación y definan potenciales estrategias de intervención al respecto.

La cooperación en América del Norte : de las seguridades económica y militar a la bioseguridad (2001-2009)

El nuevo orden internacional derivado de la Guerra Fría se caracterizó por la multiplicación de nuevas amenazas a la seguridad y la construcción de bloques regionales con el propósito de enfrentarlas. Esta investigación plantea que bajo tales circunstancias, en América del Norte, fue adoptada una agenda ampliada y profundizada en materia de seguridad que permitió articular las seguridades económica, militar y la bioseguridad. En este sentido, la configuración de dicha agenda fue posible gracias a la adopción de una retórica neoliberal de seguridad económica desde la puesta en marcha del Tratado de Libre Comercio en 1994, la cual luego del 11 de septiembre de 2001 fue articulada con la agenda de seguridad militar propuesta por el gobierno estadounidense en materia de lucha antiterrorista, que a su turno permitió la adopción de una retórica y unas medidas extraordinarias en materia de bioseguridad, motivada por los ataques bioterroristas con ántrax en EE.UU., el brote de SARS en Canadá y la pandemia de AH1N1 en México.

El papel de los principios en las fallas de los regímenes internacionales: el Fondo Monetario Internacional en la crisis económica argentina de 2001

Este trabajo de grado busca analizar el papel que juegan los principios en las fallas del Régimen Internacional de Pagos a la hora de responder a situaciones de crisis, específicamente, en la actuación del Fondo Monetario Internacional durante la crisis económica argentina de 2001. El Régimen, atado al cumplimiento de sus principios, actuó de manera tal que produjo unas fallas que terminaron exacerbando la crisis. Mediante el análisis de fuentes primarias y secundarias, y con métodos tanto cualitativos como cuantitativos se busca demostrar que efectivamente, los principios en los que se fundamentan las actuaciones de los regímenes, que son creencias, tienden a tornarse dogmáticos, por lo tanto, se hacen resistentes al cambio y no permiten a las instituciones obrar de manera que se ajuste a la realidad. Es así que los principios llegan agravar las crisis que debían solucionar, tal y como sucedió en Argentina en 2001.

Identification of potential drug targets in Salmonella Typhimurium using metabolic modelling and experimental validation

almonella enterica serovar Typhimurium is an established model organism for Gram-negative, intracellular pathogens. Owing to the rapid spread of resistance to antibiotics among this group of pathogens, new approaches to identify suitable target proteins are required. Based on the genome sequence of Salmonella Typhimurium and associated databases, a genome-scale metabolic model was constructed. Output was based on an experimental determination of the biomass of Salmonella when growing in glucose minimal medium. Linear programming was used to simulate variations in energy demand, while growing in glucose minimal medium. By grouping reactions with similar flux responses, a sub-network of 34 reactions responding to this variation was identified (the catabolic core). This network was used to identify sets of one and two reactions, that when removed from the genome-scale model interfered with energy and biomass generation. 11 such sets were found to be essential for the production of biomass precursors. Experimental investigation of 7 of these showed that knock-outs of the associated genes resulted in attenuated growth for 4 pairs of reactions, while 3 single reactions were shown to be essential for growth.

Carbamyl Analogs of Phosphatidylcholines Synthesis, Interaction With Phospholipases and Permeability Behavior of their Liposomes

A novel class of phospholipase-resisting phosphatidylcholine analogs, in which the C-2 ester group or both C-1 and C-2 ester groups have been replaced by carbamyloxy functions (-NH-C-O-), have been synthesized. These lipids were not degraded by phospholipase A2 while complete hydrolysis occurred with phospholipase C. Ultrasonic irradiation of the aqueous dispersions of the phospholipids in the presence as well as in the absence of cholesterol resulted in the formation of closed bilayer structures as evidenced by negative staining electron microscopy and also by their ability to entrap [14C]glucose. The leakage rates of glucose at 37°C from liposomes of these compounds have also been measured. Liposomes consisting of 1,2-dipentadecanylcarbamyloxy-sn-glycero- 3-phosphorylcholine were found to be more leaky (2.1 %/h) as compared to the liposomes of 1-palmitoyl-2-pentadecanylcarbamyloxy-sn -glycero-3-phosphoryl- choline (O.5%/h). Moreover, inclusion of cholesterol (33 mol%) into the bilayers of the former phospholipid had no effect on the leakage rate (2.4%/h) while it effectively reduced permeability of the latter (O.22%/h). These phosphatidylcholines are useful for studying the possible role of phospholipases in the capture and lysis of liposomes in vivo.

Stability of liposomes in circulation is markedly enhanced by structural modification of their phospholipid component

Replacement of the C-2 ester group in phosphatidylcholine by the carbamyloxy function rendered its liposomes completely stable and longer living in the circulation of rats.

Skehill, Caroline: History of the Present of Child Protection and Welfare Social Work in Ireland

This unique book has at least three significant strengths. First, it offers an interesting angle on Irish social history and how social work and child protection and welfare services have been developed from the 1860s to the 1990s. Secondly, the author uses the 'history of the present' method of Michel Foucault in a promising manner, incorporating his concepts of archaeology, genealogy and discourse. Most of all she has succeeded in further developing Michel Foucault's concepts and strategies of writing. Although this is a national history, she has made a remarkable contribution to social work research. Her conceptual and methodological innovations are undoubtedly fully applicable to other social and societal contexts. This book is recommendable to those who want to implement genealogical analysis in their own research. Thirdly, her skill in writing and the way she renders the difficult language and concepts of Michel Foucault accessible means that here is a book that can also be read with ease by those whose mother tongue is not English. From the viewpoint of women and women's research the focus in this book is minor but if you are interested in social work history and genealogical analysis, this is a book you have to read!

The relationship between adolescents’ social capital and individualism-collectivism in Estonia, Germany, and Russia

The present study examines the relationship between adolescents’ social capital and individualism-collectivism using data from the Value of Children Study (Trommsdorff and Nauck, 2005) from Estonia (N=228), Germany (N=278), and Russia (N=280). Two social capital indexes for adolescents (measuring parental social capital and peer-group social capital) were developed for the analysis. The COLINDEX Scale (Chan 1994) was used to measure individualistic and collectivistic values. In all three countries collectivistic values predicted parental social capital whereas individualistic values predicted peer-group social capital. There were also a few country-specific relationships between the constructs, with collectivism and peer-group social capital being positively related in Estonia and individualism and parental social capital signif- icantly negatively correlated in Russia. The current analysis suggests that during the adolescence, collectivistic values are more likely to be related to higher levels of parental social capital and individualistic values to higher levels of peer-group social capital. Therefore, it seems that at the individual level and for adolescents the individualism and collectivism are related to different forms of social capital in the different manner.

CONFORMATIONAL CHANGES IN THE EXTRACELLULAR DOMAIN OF GLUTAMATE RECEPTORS

The family of membrane protein called glutamate receptors play an important role in the central nervous system in mediating signaling between neurons. Glutamate receptors are involved in the elaborate game that nerve cells play with each other in order to control movement, memory, and learning. Neurons achieve this communication by rapidly converting electrical signals into chemical signals and then converting them back into electrical signals. To propagate an electrical impulse, neurons in the brain launch bursts of neurotransmitter molecules like glutamate at the junction between neurons, called the synapse. Glutamate receptors are found lodged in the membranes of the post-synaptic neuron. They receive the burst of neurotransmitters and respond by fielding the neurotransmitters and opening ion channels. Glutamate receptors have been implicated in a number of neuropathologies like ischemia, stroke and amyotrophic lateral sclerosis. Specifically, the NMDA subtype of glutamate receptors has been linked to the onset of Alzheimer’s disease and the subsequent degeneration of neuronal cells. While crystal structures of AMPA and kainate subtypes of glutamate receptors have provided valuable information regarding the assembly and mechanism of activation; little is known about the NMDA receptors. Even the basic question of receptor assembly still remains unanswered. Therefore, to gain a clear understanding of how the receptors are assembled and how agonist binding gets translated to channel opening, I have used a technique called Luminescence Resonance Energy Transfer (LRET). LRET offers the unique advantage of tracking large scale conformational changes associated with receptor activation and desensitization. In this dissertation, LRET, in combination with biochemical and electrophysiological studies, were performed on the NMDA receptors to draw a correlation between structure and function. NMDA receptor subtypes GluN1 and GluN2A were modified such that fluorophores could be introduced at specific sites to determine their pattern of assembly. The results indicated that the GluN1 subunits assembled across each other in a diagonal manner to form a functional receptor. Once the subunit arrangement was established, this was used as a model to further examine the mechanism of activation in this subtype of glutamate receptor. Using LRET, the correlation between cleft closure and activation was tested for both the GluN1 and GluN2A subunit of the NMDA receptor in response to agonists of varying efficacies. These investigations revealed that cleft closure plays a major role in the mechanism of activation in the NMDA receptor, similar to the AMPA and kainate subtypes. Therefore, suggesting that the mechanism of activation is conserved across the different subtypes of glutamate receptors.
