Manifestaciones renales en pacientes con síndrome de Alagille: Reporte de casos y revisión de la literatura.

El síndrome de Alagille es una condición autosómica dominante que se define clínicamente por alteraciones de cinco sistemas principales: escasez de ductos biliares con colestasis crónica, compromiso cardíaco (estenosis pulmonar), óseo (vétebras en mariposa), oftálmico (embriotoxon posterior) y de la cara (fascies dismórficas leves pero reconocibles). La afectación renal es común en estos pacientes; sin embargo, no hace parte de los criterios que definen el síndrome. Reportamos los casos de 3 pacientes con síndrome de Alagille y compromiso renal y realizamos una revisión de la literatura para establecer la importancia de incluir la evaluación de este sistema en el diagnóstico del síndrome. Concluimos que el compromiso renal es frecuente, y por lo tanto sugerimos que en todos los casos se evalúe la posibilidad de compromiso renal tanto a nivel estructural como funcional glomerular y tubular.

La situación de los refugiados palestinos en el Líbano a partir del Acuerdo de Taif en la década de los 90.

El interés de esta monografía es analizar la situación en la que viven los refugiados palestinos en el Líbano a partir de las políticas impuestas por el gobierno desde la década de los 90. Se analiza y explica cómo un Estado con el fin de defender su seguridad nacional se convierte en una fuente de amenazas para la seguridad humana de ciertos individuos. A través de la perspectiva de Barry Buzan se busca explicar el proceso de securitización por medio del cual los refugiados palestinos son vistos como una amenaza existencial para la seguridad nacional libanesa.

Análisis de los conceptos de la cadena de suministro y su relación con el desempeño organizacional

En el contexto de globalización, cambio y entornos más agresivos para las organizaciones, se hace necesario conocer el impacto de la administración de la cadena de suministro en el desempeño organizacional y cómo el fortalecimiento de la cadena permite a las organizaciones mantenerse en el mercado (Jacoby, 2009). Esta tendencia aplica para las organizaciones en todo el mundo, en el caso de las organizaciones Colombianas se requiere un trabajo académico donde se haga un análisis de los impactos de las cadenas de suministro en el desempeño organizacional (Ministerio de Transporte, Ministerio de Comercio, DIAN, & DNP, 2008). Una muestra de lo anterior es el hecho de que Colombia se encuentra en el puesto 97 en el ranking de desempeño logístico hecho por el Banco Mundial en 2014 (Banco Mundial, 2014). Esto demuestra la necesidad de mejorar los procesos logísticos en el país mediante el fortalecimiento de las cadenas de suministros, permitiendo una mayor eficiencia y capacidad de respuesta ante las demandas globales de los diferentes mercados en un entorno cambiante y agresivo. Por lo anterior se debe comprender y dimensionar el potencial impacto que tenga el desempeño organizacional y la correcta gestión de la cadena de suministros en el contexto Colombiano. Por consiguiente a través de una exhaustiva revisión literaria se buscaran los puntos de convergencia entre el desempeño organizacional y la cadena de suministros, haciendo uso del modelo Balance Score Card para analizar desde las perspectivas financiera, clientes, procesos internos e innovación y aprendizaje de las organizaciones, las actividades que involucran las cadena de suministro: aprovisionamiento, producción y distribución.

La dimensión transnacional del movimiento feminista marroquí: génesis, desarrollo e impacto social (1980-2008)

Esta monografía busca explicar cómo han incidido el contexto internacional y las relaciones transnacionales en el movimiento feminista de Marruecos. De este modo, este estudio defiende que las Conferencias Mundiales sobre la Mujer de la ONU crearon una estructura de oportunidad política que favoreció el surgimiento y el desarrollo de este movimiento. Asimismo, dicho contexto construyó un espacio para que las activistas feministas marroquíes crearan y se insertaran en Redes de Defensa Transnacional, las cuales contribuyeron a cambiar la condición de la mujer en Marruecos, a través de reformas a los Códigos de Familia y Nacionalidad y el levantamiento de las reservas a la CEDAW. Para esto se hará un estudio interdisciplinario haciendo uso de la teoría de los movimientos sociales y del activismo transnacional. Igualmente, se utilizará una metodología cualitativa, principalmente a través de las herramientas del análisis de contenido y el trabajo de campo de la autora.

Manipulation of Dhaka cheese curd and effects on cheese quality

Dhaka cheese is a semihard artisanal variety originating from Bangladesh where manual curd kneading is a normal stage in its manufacture. Dhaka cheeses were produced with different degrees of curd kneading to quantify the curd manipulation process in terms of pressure and to standardise the length of operation. The effect of manipulation on the composition, rheology, texture and microstructure of fresh cheese was also studied. Manipulation had significant effects (P < 0.05–0.001) on most of the parameters studied. One minute of curd manipulation was found to be sufficient for Dhaka cheesemaking

Pressing technique and its effect on the quality of Dhaka cheese

Dhaka cheese is a semihard artisanal variety made mainly from bovine milk, using very simple pressing methods. Experimental cheeses were pressed at gauge pressures up to 31 kPa for 12 h at 24 °C and 70% RH. These cheeses were subsequently examined for their compositional, textural and rheological properties plus their microstructures investigated by confocal laser microscopy. The cheese pressed at 15.6 kPa was found to have the best compositional and structural properties.

Diallyl disulfide-induced apoptosis in a breast-cancer cell line (MCF-7) may be caused by inhibition of histone de-acetylation

The health benefits of garlic have been proven by epidemiological and experimental studies. Diallyl disulphide (DADS), the major organosulfur compound found in garlic oil, is known to lower the incidence of breast cancer both in vitro and in vivo. The studies reported here demonstrate that DADS induces apoptosis in the MCF-7 breast-cancer cell line through interfering with cell-cycle growth phases in a way that increases the sub-G0 population and substantially halts DNA synthesis. DADS also induces phosphatidylserine (PS) translocation from the inner to the outer leaflet of the plasma membrane and activates caspase-3. Further studies revealed that DADS modulates the cellular levels of Bax, Bcl-2, Bcl-xL and Bcl-w in a dose-dependent manner, suggesting the involvement of Bcl-2 family proteins in DADS induced apoptosis. Histone deacetylation inhibitors (HDACi) are known to suppress cancer growth and induce apoptosis in cancer cells. Here it is shown that DADS has HDACi properties in MCF-7 cells as it lowers the removal of an acetyl group from an acetylated substrate and induces histone-4 (H4) hyper-acetylation. The data thus indicate that the HDACi properties of DADS may be responsible for the induction of apoptosis in breast cancer cells.

Prolonged exposure to palmitate impairs fatty acid oxidation despite activation of AMP-activated protein kinase in skeletal muscle cells

The aim of this study was to investigate the chronic effects of palmitate on fatty acid (FA) oxidation, AMPK/ACC phosphorylation/activation, intracellular lipid accumulation, and the molecular Mechanisms involved in these processes in skeletal muscle cells. Exposure of L6 myotubes for 8 h to 200, 400, 600, and 800 mu M of palmitate did rot affect cel viability but significantly reduced FA oxidation by similar to 26.5%, similar to 43.5%, similar to 50%, and similar to 47%, respectively. Interestingly, this occurred despite significant increases in AMPK (similar to 2.5-fold) and ACC (similar to 3-fold) phosphorylation and in malonyl-CoA decarboxylase activity (similar to 38-60%). Low concentrations of palmitate (50-100 mu M) caused an increase (similar to 30%) in CPT-I activity. However, as the concentration of palmitate increased, CPT-I activity decreased by similar to 32% after exposure for 8 h to 800 mu M of palmitate. Although FA uptake was reduced (similar to 35%) in cells exposed to increasing, palmitate concentrations, intracellular lipid accumulation increased in a dose-dependent manner, reaching values similar to 2.3-, similar to 3-, and 4-fold higher than control in muscle cells exposed to 400, 600, and 800 mu M palmitate, respectively. Interestingly, myotubes exposed to 400 mu M of palmitate for 1h increased basal glucose uptake and glycogen synthesis by similar to 40%. However, as time of incubation in the presence of palmitate progressed from 1 to 8h, these increases were abolished and a time-dependent inhibition of insulin-stimulated glucose uptake (similar to 65%) and glycogen synthesis (30%) was observed in myotubes. These findings may help explain the dysfunctional adaptations that occur in glucose and FA Metabolism in skeletal muscle under conditions of chronically elevated circulating levels of non-esterified FAs. Such as in obesity and Type 2 Diabetes.

GLP-1 Inhibits and Adrenaline Stimulates Glucagon Release by Differential Modulation of N- and L-Type Ca(2+) Channel-Dependent Exocytosis

Glucagon secretion is inhibited by glucagon-like peptide-1 (GLP-1) and stimulated by adrenaline. These opposing effects on glucagon secretion are mimicked by low (1-10 nM) and high (10 mu M) concentrations of forskolin, respectively. The expression of GLP-1 receptors in a cells is <0.2% of that in beta cells. The GLP-1-induced suppression of glucagon secretion is PKA dependent, is glucose independent, and does not involve paracrine effects mediated by insulin or somatostatin. GLP-1 is without much effect on a cell electrical activity but selectively inhibits N-type Ca(2+) channels and exocytosis. Adrenaline stimulates a cell electrical activity, increases [Ca(2+)] enhances L-type Ca(2+) channel activity, and accelerates exocytosis. The stimulatory effect is partially PKA independent and reduced in Epac2-deficient islets. We propose that GLP-1 inhibits glucagon secretion by PKA-dependent inhibition of the N-type Ca(2+) channels via a small increase in intracellular cAMP ([cAMP]). Adrenaline stimulates L-type Ca(2+) channel-dependent exocytosis by activation of the low-affinity cAMP sensor Epac2 via a large increase in [cAMP],.

QoS evaluation of Bandwidth Schedulers in IPTV Networks Offered SRD Fluid Video Traffic

Internet protocol TV (IPTV) is predicted to be the key technology winner in the future. Efforts to accelerate the deployment of IPTV centralized model which is combined of VHO, encoders, controller, access network and Home network. Regardless of whether the network is delivering live TV, VOD, or Time-shift TV, all content and network traffic resulting from subscriber requests must traverse the entire network from the super-headend all the way to each subscriber's Set-Top Box (STB). IPTV services require very stringent QoS guarantees When IPTV traffic shares the network resources with other traffic like data and voice, how to ensure their QoS and efficiently utilize the network resources is a key and challenging issue. For QoS measured in the network-centric terms of delay jitter, packet losses and bounds on delay. The main focus of this thesis is on the optimized bandwidth allocation and smooth data transmission. The proposed traffic model for smooth delivering video service IPTV network with its QoS performance evaluation. According to Maglaris et al [5] first, analyze the coding bit rate of a single video source. Various statistical quantities are derived from bit rate data collected with a conditional replenishment inter frame coding scheme. Two correlated Markov process models (one in discrete time and one in continuous time) are shown to fit the experimental data and are used to model the input rates of several independent sources into a statistical multiplexer. Preventive control mechanism which is to be including CAC, traffic policing used for traffic control. QoS has been evaluated of common bandwidth scheduler( FIFO) by use fluid models with Markovian queuing method and analysis the result by using simulator and analytically, Which is measured the performance of the packet loss, overflow and mean waiting time among the network users.

Micro finance programs: caring for those missed by formal social protection mechanism

In line with the current global trend of economic and social restructuring, it has become essential to address the issue of poverty and social protection for the poorer segment of the population who are not covered by formal social protection mechanisms. Micro finance institutions (MFIs) in developing countries have been working towards poverty alleviation and enhancing social protection for the last few decades. MFI’s provision of financial assistance to the poor has been instrumental in improving the overall quality of the impoverished. Based on an in-depth qualitative study conducted across three different types of NGOs (Non Governmental Organization) in the Philippines, this study found a relationship between micro finance programs and improved social protection. The study reveals that MFIs have the ability to make a positive impact on areas such as entrepreneurship, education, housing, job security and income generation.

Understanding what microfinance institutions need to address to aid poverty alleviation, social inclusion and human development

Poverty, in its most basic form can be defined as a deprivation of well-being. It is an issue that has been evident in society for centuries and a concern for government policy makers and more recently for non-government organizations (NGOs). In this paper, we consider how management approaches to resolving the dilemma of poverty can be advanced by drawing on two major areas in the development arena associated with poverty, namely, ‘social exclusion’ and ‘the human development paradigm’. We put forward the argument that for groups of people where social disintegration has already occurred, only structural interventions coupled with a social development mechanism will achieve the desired effect. One method for achieving this is through the use of microfinance programs which provide a broad range of financial services to the poor and low-income households as well as to micro-enterprises. This paper contributes to both management practice and theory by developing a theoretical model that microfinance institutions need to do to aid both ‘human development’ and ‘social inclusion’ processes for the socially excluded and poor.

Fighting the digital divide with microfinance : building social capital and socio-economic development

Unlike other technology, lCT has the tremendous capacity to eliminate various social and economic barriers impeding the poor, helping them discover their potential. Wider access and use of lCT can improve social networks and increase civic engagement, thereby improving social fabric and developing social capital. Thus, scholars now have realized lCT plays a primary role in the formation and maintenance of social network. This paper identifies microfinance programs as an agent with unparalleled capacity to facilitate access to lCT and thus the formation of social capital and socio-economic development of the poor. In this paper, we also discuss the role of MFls in developing social capital in
South Asia and present an analytical model of how the intervention of microfinance can facilitate access to lCT by the poor with the result of an improved both socio-economic situation and social capital.
