The suitability of steam exploded vitis vinifera and alkaline lignin for the manufacture of fiberboard

The main objective of this study was to explore the suitability of Vitis vinifera as a raw material and alkaline lignin as a natural binder for fiberboard manufacturing. In the first step, Vitis vinifera was steam- exploded through a thermo-mechanical vapor process in a batch reactor, and the obtained pulp was dried, ground, and pressed to produce the boards. The effects of pretreatment factors and pressing conditions on the chemical composition of the fibers and the physico-mechanical properties of binderless fiberboards were evaluated, and the conditions that optimize these properties were found. A response surface method based on a central composite design and multiple-response optimization was used. The variables studied and their respective variation ranges were: pretreatment temperature (Tr: 190-210ºC), pretreatment time (tr: 5-10 min), pressing temperature (Tp: 190-210ºC), pressing pressure (Pp: 8-16MPa), and pressing time (tp: 3-7min). The results of the optimization step show that binderless fiberboards have good water resistance and weaker mechanical properties. In the second step, fiberboards based on alkaline lignin and Vitis vinifera pulp produced at the optimal conditions determined for binderless fiberboards were prepared and their physico-mechanical properties were tested. Our results show that the addition of about 15% alkaline lignin leads to the production of fiberboards that fully meet the requirements of the relevant standard specifications

TRPV4-associated skeletal dysplasias.

Dominant mutations in the TRPV4 gene result in a bone dysplasia family and form a continuous phenotypic spectrum that includes, in decreasing severity, lethal, and nonlethal metatropic dysplasia (MD), spondylometaphyseal dysplasia Kozlowski type (SMDK), and autosomal dominant brachyolmia. Several rare variant phenotypes that have some overlap but deviate in some ways from the general pattern have also been described. The known variant phenotypes are spondyloepiphyseal dysplasia Maroteaux type (Pseudo-Morquio type 2), parastremmatic dysplasia, and familial digital arthropathy with brachydactyly. Interestingly, different TRPV4 mutations have been associated with dominantly inherited neurologic disorders such as congenital spinal muscular atrophy and hereditary motor and sensory neuropathy. Finally, a small number of patients have been identified in whom a TRPV4 mutation results in a phenotype combining skeletal dysplasia with peripheral neuropathy. The TRPV4 gene encodes a regulated calcium channel implicated in multiple and diverse cellular processes. Over 50 different TRPV4 mutations have been reported, with two codons appearing to be mutational hot spots: P799 in exon 15, mostly associated with MD, and R594 in exon 11, associated with SMDK. While most pathogenic mutations tested so far result in activation of the calcium channel in vitro, the mechanisms through which TRPV4 activation results in skeletal dysplasia and/or peripheral neuropathy remain unclear and the genotype-phenotype correlations in this group of disorders remains somewhat mysterious. Since the phenotypic expression of most mutations seems to be relatively constant, careful clinical and radiographic assessment is useful in directing molecular analysis. © 2012 Wiley Periodicals, Inc.

A mixed approach for proving non-inferiority in clinical trials with binary endpoints

When a new treatment is compared to an established one in a randomized clinical trial, it is standard practice to statistically test for non-inferiority rather than for superiority. When the endpoint is binary, one usually compares two treatments using either an odds-ratio or a difference of proportions. In this paper, we propose a mixed approach which uses both concepts. One first defines the non-inferiority margin using an odds-ratio and one ultimately proves non-inferiority statistically using a difference of proportions. The mixed approach is shown to be more powerful than the conventional odds-ratio approach when the efficacy of the established treatment is known (with good precision) and high (e.g. with more than 56% of success). The gain of power achieved may lead in turn to a substantial reduction in the sample size needed to prove non-inferiority. The mixed approach can be generalized to ordinal endpoints.

Ocorrências éticas com profissionais de enfermagem: um estudo quantitativo

Este trabalho teve por objetivo identificar as características das ocorrências éticas, envolvendo a assistência de enfermagem, em um hospital particular de grande porte do município de São Paulo. Houve 190 ocorrências comunicadas à Comissão de Ética de Enfermagem (CEE) da Instituição, entre 1995 e 2004. Na maioria das ocorrências éticas não houve dano ao paciente, nem à Instituição de saúde ou ao profissional envolvido. Do total de 398 providências tomadas, em 94,5% dos casos foram de orientações dadas pela CEE aos profissionais de enfermagem, destacando-se também orientações feitas pela chefia imediata deles. Em 93,7% das ocorrências, envolvia apenas um profissional. As unidades de internação constituíram o cenário para 76,3% das ocorrências éticas. Como resultado, pode-se mencionar que o estudo demonstrou a importância da orientação aos profissionais, para prevenir ocorrências danosas à clientela.

Lateralization of olfactory processing: Differential impact of right and left temporal lobe epilepsies.

Olfactory processes were reported to be lateralized. The purpose of this study was to further explore this phenomenon and investigate the effect of the hemispheric localization of epileptogenic foci on olfactory deficits in patients with temporal lobe epilepsy (TLE). Olfactory functioning was assessed in 61 patients and 60 healthy control (HC) subjects. The patients and HC subjects were asked to rate the intensity, pleasantness, familiarity, and edibility of 12 common odorants and then identify them. Stimulations were delivered monorhinally in the nostril ipsilateral to the epileptogenic focus in TLE and arbitrarily in either the left or the right nostril in the HC subjects. The results demonstrated that regardless of the side of stimulation, patients with TLE had reduced performance in all olfactory tasks compared with the HC subjects. With regard to the side of the epileptogenic focus, patients with left TLE judged odors as less pleasant and had more difficulty with identification than patients with right TLE, underlining a privileged role of the left hemisphere in the emotional and semantic processing of odors. Finally, irrespective of group, a tendency towards a right-nostril advantage for judging odor familiarity was found in agreement with a prominent role of the right hemisphere in odor memory processing.

Situação de trabalho dos profissionais da Estratégia Saúde da Família em Ceará-Mirim

O objetivo deste estudo foi analisar as situações de trabalho vivenciadas pelos profissionais da Estratégia Saúde da Família (ESF). Estudo descritivo realizado em Ceará-Mirim, Rio Grande do Norte, em 2007. A população constituiu-se de 190 profissionais da ESF, na qual foi aplicada um questionário com questões fechadas. Os resultados apontaram que o conhecimento da área geográfica adstrita pelos profissionais da ESF foi considerado como um aspecto positivo para a realização das atividades executadas por 83,2% dos profissionais, e o número de famílias acompanhadas por equipe foi considerado como uma dificuldade por 40,5%. Em relação às condições de trabalho, 93,2% referiram a presença de profissionais com perfil em saúde pública, e 86,8%, indisponibilidade de equipamentos e instrumentos. Dos profissionais que trabalham exclusivamente na ESF, 74% são agentes comunitários de saúde. O compromisso e a responsabilidade para substituir as práticas tradicionais de assistência devem ser de todos, havendo a necessidade de interação de fatores históricos, políticos, sociais, econômicos e culturais.
