El asma bronquial es una enfermedad inflamatoria crónica, se asocia a hiperrespuesta de la vía aérea, la cual lleva a episodios recurrentes de sibilancias, tos y disnea. La entidad se ha correlacionado con una gran variedad de genes involucrados en su fisiopatología, dentro de los cuales se encuentran genes localizados en el cromosoma 5 (5q23-31), como el del Receptor ß2 Adrenérgico (RB2A). En el presente trabajo se realizó una estimación de las frecuencias de los polimorfismos Arg16Gly, Gln27Glu y Thr164Ile de este receptor, y se estudió la relación existente entre los diferentes polimorfismos y asma, así como su relación con respecto a la severidad de la enfermedad, finalmente se estimó la relación de los haplotipos conformados por estos tres polimorfismos y su asociación con la enfermedad y severidad del fenotipo asmático.

Resumen del autor
Resumo:
This paper develops a model of the regulator-regulated firm relationship in a regional natural gas commodity market which can be linked to a competitive market by a pipeline. We characterize normative policies under which the regulator, in addition to setting the level of the capacity of the pipeline, regulates the price of gas, under asymmetric information on the firm’s technology, and may (or may not) operate (two-way) transfers between consumers and the firm. We then focus on capacity and investigate how its level responds to the regulator’s taking account of the firm’s incentive compatibility constraints. The analysis yields some insights on the role that transport capacity investments may play as an instrument to improve the efficiency of geographically isolated markets.

Alpha-synuclein is found in synaptic terminals at the base of both inner and outer hair cells, while the beta isoform is prominently localized to spiral ganglion neuron cell bodies. The present study assessed the role of beta-synuclein in auditory function, and potential interactions between isoforms.
Down-regulation of the CSLF6 gene results in decreased (1,3;1,4)-beta-D-glucan in endosperm of wheat
Resumo:
(1,3;1,4)-beta-d-Glucan (beta-glucan) accounts for 20% of the total cell walls in the starchy endosperm of wheat (Triticum aestivum) and is an important source of dietary fiber for human nutrition with potential health benefits. Bioinformatic and array analyses of gene expression profiles in developing caryopses identified the CELLULOSE SYNTHASE-LIKE F6 (CSLF6) gene as encoding a putative beta-glucan synthase. RNA interference constructs were therefore designed to down-regulate CSLF6 gene expression and expressed in transgenic wheat under the control of a starchy endosperm-specific HMW subunit gene promoter. Analysis of wholemeal flours using an enzyme-based kit and by high-performance anion-exchange chromatography after digestion with lichenase showed decreases in total beta-glucan of between 30% and 52% and between 36% and 53%, respectively, in five transgenic lines compared to three control lines. The content of water-extractable beta-glucan was also reduced by about 50% in the transgenic lines, and the M(r) distribution of the fraction was decreased from an average of 79 to 85 x 10(4) g/mol in the controls and 36 to 57 x 10(4) g/mol in the transgenics. Immunolocalization of beta-glucan in semithin sections of mature and developing grains confirmed that the impact of the transgene was confined to the starchy endosperm with little or no effect on the aleurone or outer layers of the grain. The results confirm that the CSLF6 gene of wheat encodes a beta-glucan synthase and indicate that transgenic manipulation can be used to enhance the health benefits of wheat products.
