Poor quality of life (QOL) and a high prevalence of depression have been identified among end-stage renal disease (ESRD) patients undergoing hemodialysis (HD). We aimed to evaluate the associations between religious/spiritual (R/S) coping methods and both QOL and depression among ESRD patients undergoing hemodialysis (HD).The sample included 161 ESRD patients over 18 years of age who had been undergoing HD for more than 3 months. R/S coping methods were assessed using the Religious Coping Questionnaire ( ...

Sexual function among women undergoing hemodialysis (HD) is under-studied and there is no consensus about the effect of sexual dysfunction (SD) on their quality of life (QoL). We aimed to determine the prevalence of SD and to compare QoL between women undergoing maintenance HD with and without SD.We included female end-stage renal disease (ESRD) patients undergoing HD during June 2011 in the only renal unit in the north of Ceará state, northeastern Brazil. The criteria for inclusion were age between ...

Abstract The possible involvement of the endothelium in the vasodilator action of eugenol was investigated in the mesenteric vascular bed (MVB) of the rat. Bolus injections of eugenol (0.2, 2 and 20 μmol) and acetylcholine (ACh; 10, 30 and 100 pmol) induced dose-dependent vasodilator responses in noradrenaline-precontracted beds that were partially inhibited by pretreatment of the MVB with deoxycholate (1 mg mL−1) to remove the endothelium (˜ 14% and ˜ 30% of the control response remaining at the lowest ...

Resonant Raman scattering from LO phonons in the presence of a constant magnetic field is considered. We calculate the differential extinction coefficient, including effects of the electron-phonon interaction, for a doped semiconductor. It is shown that significant deviations from the Lorentzian line shape may appear due to hybridization of the phonon mode with the cyclotron modes, when for certain geometries, a harmonic of the cyclotron frequency is approximately equal to the LO-phonon frequency. ...

Corynebacterium pseudotuberculosis is the aetiological agent of caseous lymphadenitis (CLA), a debilitating disease of sheep and goats. Accurate diagnosis of CLA primarily relies on microbiological examination, followed by biochemical identification of isolates. In an effort to facilitate C. pseudotuberculosis detection, a multiplex PCR (mPCR) assay was developed targeting three genes of this bacterium: the 16S rRNA gene, rpoB and pld. This method allowed efficient identification of 40 isolates of ...

Expressivo número de municípios amazonenses se encontra localizado em áreas carentes em agregados pétreos, o que leva os construtores de pavimentos a adotarem alternativas que, em retrospecto histórico, propiciam pavimentos de deficiente resistência mecânica. Conquanto mais eficaz e apropriado do ponto de vista técnico, o concreto betuminoso usinado à quente é normalmente evitado por conta da indicada carência estadual em agregados pétreos. Em face do peculiar contexto amazonense, revela-se recomendável ...

Background: It appears there are no studies evaluating the influence of the bisphosphonate tiludronic acid (TIL) on periodontitis. The purpose of this study is to evaluate via microtomographic, histopathologic, histometric, and immunohistochemical analyses the effects of local administration of TIL on ligature‐induced periodontitis in rats. Methods: Forty‐eight rats were divided into six groups: C (control), EP (experimental periodontitis), EP‐Saline, EP‐TIL0.1, EP‐TIL0.3, and EP‐TIL1. In EP, a ligature ...

Human L-asparaginase-like protein 1 (ASRGL1) has hydrolytic activity against L-asparagine and isoaspartyl dipeptides. As an N-terminal nucleophile hydrolase family member, its activation depends on an intramolecular autoprocessing step between G167 and T168. In vitro, autoprocessing reaches only 50% completion, which restrains the activity and hampers the full understanding of the activation process. The ASRGL1 dimer interface plays a critical role in intramolecular processing, and the interactions ...

The CYFIP2 protein (cytoplasmic FMR1-interacting protein 2) is part of the WAVE regulatory complex (WRC). CYFIP2 was recently correlated to neurological disorders by the association of the R87C variant with early infantile epileptic encephalopathy (EIEE) patients. In this set of syndromes, the epileptic spasms and seizures since early childhood lead to impaired neurological development in children. Inside the WRC, the variant residue is at the CYFIP2 and WAVE1 protein interface. Thus, the hypothesis ...

Multiple auditory steady-state response (MASSR) is recommended to estimate hearing thresholds in difficult-to-test individuals. The multiple stimuli that evoke MASSR may present an interstimulus interaction (ISI) that is able to distort the generation of responses. No consensus exists on the effects of the ISI in MASSR when dealing with high sound level stimuli or cases of sensorineural hearing loss. This study investigated the effects of ISI on the amplitude and detectability of auditory steady-state ...

The Pantanal floodplains of Brazil are a region of rich biodiversity. To date, the true richness of the Pantanal avifauna has not been explored satisfactorily caused by a lack of studies in the region and, especially, by the divergence of opinion among the works published by various authors on the many species found in the region. This is due to the lack of criteria in examining records, both with regard to the reliability of the identifications and in the precise geographical allocation. Therefore, ...
