Postnatal developmental expression of the PDZ scaffolds Na+-H+ exchanger regulatory factors 1 and 2 in the rat cochlea

Sensory transduction in the mammalian cochlea requires the maintenance of specialized fluid compartments with distinct ionic compositions. This is achieved by the concerted action of diverse ion channels and transporters, some of which can interact with the PDZ scaffolds, Na+-H+ exchanger regulatory factors 1 and 2 (NHERF-1, NHERF-2). Here, we report that NHERF-1 and NHERF-2 are widely expressed in the rat cochlea, and that their expression is developmentally regulated. Reverse transcription/polymerase chain reaction (RT-PCR) and Western blotting initially confirmed the RNA and protein expression of NHERFs. We then performed immunohistochemistry on cochlea during various stages of postnatal development. Prior to the onset of hearing (P8), NHERF-1 immunolabeling was prominently polarized to the apical membrane of cells lining the endolymphatic compartment, including the stereocilia and cuticular plates of the inner and outer hair cells, marginal cells of the stria vascularis, Reissner's epithelia, and tectorial membrane. With maturation (P21, P70), NHERF-1 immunolabeling was reduced in the above structures, whereas labeling increased in the apical membrane of the interdental cells of the spiral limbus and the inner and outer sulcus cells, Hensen's cells, the inner and outer pillar cells, Deiters cells, the inner border cells, spiral ligament fibrocytes, and spiral ganglion neurons (particularly type II). NHERF-1 expression in strial basal and intermediate cells was persistent. NHERF-2 immunolabeling was similar to that for NHERF-1 during postnatal development, with the exception of expression in the synaptic regions beneath the outer hair cells. NHERF-1 and NHERF-2 co-localized with glial fibrillary acidic protein and vimentin in glia. The cochlear localization of NHERF scaffolds suggests that they play important roles in the developmental regulation of ion transport, homeostasis, and auditory neurotransmission.

CRISTOLOGIA ANGELOMÓRFICA DE HEBREUS Estudo Sócio-Retórico e História das Religiões Comparadas em Hebreus 1.1-14; 2.5-18; 7.1-10

A Epístola aos Hebreus apresenta já em seus primeiros versos Jesus Cristo assentado à destra de Deus (Hebreus 1,1-4). Assim, desde o princípio a Carta aos Hebreus revela a estratégia de seu autor ao expressar Jesus Cristo em termos honrosos. Tais indícios sugerem o meio ambiente cultural típico do mundo mediterrâneo do século I E.C., em que honra e vergonha exerciam uma função pivô nessa sociedade. A estratégia de Hebreus apresenta a dignidade de Jesus Cristo e sustenta o controle social de seus leitores diante de uma eminente evasão do grupo religioso. Para isso, o autor de Hebreus lança mão de tradições angelológicas amplamente conhecidas do entorno religioso judaico do período do segundo templo. Caracterizam principalmente essas tradições elementos gloriosos desenvolvidos pela religião judaica (anjos, figuras hipostáticas, Melquisedec), que contribuíram para a confissão do Cristo exaltado de Hebreus. Fazemos um estudo da História das Religiões Comparadas das figuras mediadoras nos escritos do AT e da literatura pseudepígrafa, entendendo que essas figuras foram adquirindo cada vez mais características divinizadas possibilitando a elaboração da Cristologia angelomórfica de Hebreus 1.1-14; 2.5-18; 7.1-10. Além disso, uma aproximação sócio-retórica à Hebreus garante resultados mais claros no que diz respeito à estratégia pretendida por seu autor.

Lipoplexes formulation and optimisation:in vitro transfection studies reveal no correlation with in vivo vaccination studies

The aim of these studies was to compare the effect of liposome composition on physico-chemical characteristics and transfection efficacy of cationic liposomes both in vitro and in vivo. Comparison between 4 popularly used cationic lipids, showed 3b-N-(dimethylaminoethyl)carbamate (DC-Chol) to promote the highest transfect levels in cells in vitro with levels being at least 6 times higher than those of 1,2-di-O-octadecenyl-3-trimethylammonium propane (DOTMA). 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP), and dimethyldioctadecylammonium (DDA) and approximately twice as efficient as dipalmitoyl-trimethylammonium-propane (DPTAP). To establish the role of the helper lipid, DC-Chol liposomes were formulated in combination with either 1,2-dioleoyl-sn-glycero-3-phosphatidylethanolamine (DOPE) or cholesterol (Chol) (1:1 molar ratio) with and without the addition of phosphatidyl choline. The choice of helper lipid incorporated within the bilayer was found to influence the formation of complexes, their resultant structure and their transfection efficiency in vitro, with SUV-DNA complexes containing optimum levels of DOPE giving higher transfection than those containing cholesterol. The inclusion of PC within the formulation also reduced transfection efficiency in vitro. However, when administered in vivo, SUV-DNA complexes composed of PC:Chol:DC-Chol at a molar ratio of 16:8:4 micromole/ml were the most effective at inducing splenocyte proliferation upon exposure to antigen in comparison to control spleens. These results demonstrate that there is no in vitro/in vivo correlation between the transfection efficacy of these liposome formulations and in vitro transfection in the above cell model cannot be taken as a reliable indicator for in vivo efficacy of DNA vaccines.

Predictors of maternal control of feeding at 1 and 2 years of age

Objective: To establish the best predictors of maternal use of controlling feeding practices at 1 and 2 years of age. Design: A longitudinal study from birth to 2 years. Participants: Sixty-two mothers of 2-year-old children. Measures: Infant weight at birth, 6, 12 and 24 months, breastfeeding history, infant temperament and feeding difficulties at 6 and 12 months, maternal demographics at 12 and 24 months, maternal mental health at 6 and 12 months, maternal controlling feeding practices at 12 and 24 months. Results: Controlling feeding practices at 1 year were predicted by perceptions of infant temperament at 6 months, birth weight, length of breastfeeding, mental health at 6 months, and mealtime negativity at 6 months. Parental control over feeding when their child reached 2 years was predicted by the mother's tendency to use that particular strategy at 1 year in combination with the perceptions of infant temperament and feeding problems at 1 year, weight at 1 year, length of breastfeeding in infancy, and/or maternal mental health at 1 year. Conclusions: Breastfeeding appears to promote subsequent monitoring, and is associated with reduced use of pressurising and restrictive feeding practices. Infant characteristics are important predictors of control at both 1 and 2 years of age. The use of controlling feeding practices is relatively stable from 1 to 2 years. © 2007 Nature Publishing Group All rights reserved.

Toll-like receptor 4 signalling is neither sufficient nor required for oxidised phospholipids mediated induction of interleukin-8 expression

Toll-like receptor (TLR)-4 signalling has been shown to accelerate atherosclerosis. As oxidised phospholipids are present in atherosclerotic plaque and have been shown to modulate TLR4 signalling, we investigated the role of oxidised 1-palmitoyl-2-arachidonyl-sn-glycero-3-phosphorylcholine (OxPAPC) in the regulation of TLR 1, 2, 4 and 6 signalling. Unlike established TLR agonists, OxPAPC did not induce NF-?B-dependent gene expression in monocytic THP-1 cells, human aortic endothelial cells or TLR-deficient HEK-293 cells transfected with TLRs 1, 2, 4 or 6. OxPAPC induction of IL-8 was not blocked by the TLR4 specific antagonist Rhodobacter sphaeroides LPS in human aortic endothelial cells, though OxPAPC potently inhibited TLR4 mediated IL-8 induction in these cells. OxPAPC upregulated IL-8 production in TLR4 deficient HEK-293 cells and this was not increased following TLR4 overexpression. Lipids extracted from carotid atherectomy samples did not stimulate TLR 1, 2, 4 or 6 signalling in a HEK-293 transfection assay. TLR4 signalling does not contribute to OxPAPC induced IL-8 expression in human epithelial HEK-293, monocytic THP-1 or aortic endothelial cells. As lipids extracted from diseased human artery also induced no TLR signalling, it is likely that the TLR-activating materials contributing to atherosclerosis are not of endogenous lipid origin.
