Abstract: background & purpose: the association of obstructive sleep apnea syndrome (osas) and restless legs syndrome (rls) has been reported in the literature for many years. both conditions may be responsible for fatigue and somnolence complaints secondary to nocturnal sleep disruption. the primary concern of this study is to evaluate the outcome of fatigue and daytime sleepiness symptoms at baseline and after continuous positive air pressure (cpap) treatment in osas patients with and without rls. method: a prospective and comparative study between a group of 13 patients with osas and a group of 17 patients with osas+rls. laboratory blood tests and polysomnography were performed at baseline. the epworth sleepiness scale (ess) and the pichot?s questionnaire of fatigue/depression (pic) were applied before and after 3 months of cpap treatment. results were compared. results: no significant differences were found on psg and laboratory results at baseline. both groups had similar ess and pic scores at baseline (p=0.73 and 0.08, respectively). after n-cpap, osas+rls patients showed higher ess and pic scores (p=0.017 and 0.03, respectively). conclusions: despite a favorable general response, n-cpap seemed less effective in treating fatigue and sleepiness in the osas+rls group.

Rezende, Erika Luiza Lage Fazito;Vasconcelos, Ana Maria Nogales;Pereira, Mauricio Gomes;
Brazilian Journal of Infectious Diseases , 2010, DOI: 10.1590/S1413-86702010000600003
Abstract: background: the monitoring of the underlying causes of death in people living with hiv/aids is important so that actions to reduce morbidity and mortality can be taken. objective: to describe the temporal trends of underlying causes of death among people living with hiv/aids between 2000 and 2007 in brazil and to identify factors associated with it. methods: the mortality information system data for deaths occurred in brazil between 2000 and 2007 that contained reference to hiv/aids in any of the death certificate fields was analyzed. temporal trends of the underlying cause of death were studied. differences in the underlying cause of death according to gender, age, region of residence, level of education, certifying officer, race and year of death were verified. results: between 2000 and 2007 the percentage of deaths not related to hiv/aids among people living with hiv/aids increased from 2.5% to 7.0%. people with higher level of formal education, living in the south-east region of brazil and aged under 13 or over 60 years old were more likely to have their underlying cause of death reported as not related to hiv/aids. conclusion: the results suggest the importance of implementing actions aimed at improving the quality of life of plwha, and which could include behavioral changes, such as smoking and alcoholism cessation, early screening to detect neoplasms and the monitoring of chronic conditions, such as diabetes. that is to say, the need exists to integrate the actions of hiv/aids programs with other public health programs.

Cruz, Fernando William;Cunha, Murilo Bastos da;Ferneda, Edilson;Alonso, Luiza Beth Nunes;Vasconcelos, Ana Maria Nogales;
Perspectivas em Ciência da Informa??o , 2011, DOI: 10.1590/S1413-99362011000200013
Abstract: despite the good results generated by studies of uses and needs of musical information published in the last years, there is lack of basic referential to support the organization of concepts and the mapping of variables associated to the phenomena that are object of investigation. this paper presents a behavioral model for the needs and usage of musical information that can facilitate the identification of variables of analysis and production of instruments for data collecting in quantitative and qualitative studies. in order to validate the proposed conceptual model, the results of one application of the model in a quantitative exploratory study with non specialized users of music are presented.
Avalia??o do sistema de vigilancia entomológica da doen?a de Chagas com participa??o comunitária em Mambaí e Buritinópolis, Estado de Goiás

Abstract: entomological surveillance of chagas disease in mambaí and buritinópolis, in the state of goiás, brazil, has been kept up through the local population's participation, consisting of reporting the presence of vectors inside their homes. a long time has elapsed since instituting these control measures and it has now been certified that vector transmission has been halted. thus, this study sought to evaluate the population's knowledge and practices in this situation. the results show that there has been progressive indifference towards the topic of "chagas disease", which can be attributed to the reduction in the magnitude of the problem that this disease represented, little participation in surveillance among schools, low epidemiological importance of secondary and native vectors and, consequently, limited control interventions from health services in response to notifications. it is proposed that direct search activities by means of sampling should be carried out periodically, and that there should be greater involvement among teaching institutions.

Weight/length relationships, condition factor, gonadosomatic and hepatosomatic indices, conversion factor for gutted to total weight and spawning season of hake in the Portuguese Coast (36.92 to 42.22 degrees latitude N; 9.61 to 6.07 degrees longitude W) were investigated for the first time, aiming to fill the lack of information on the biology of hake of the Portuguese waters. Data were obtained from commercial samples collected between 2005 and 2010 and pooled by month. Sex ratio observed in fish below 40 cmwas close to 1:1; females were always dominant above50 cmlength. All the parameters were analysed by month and by sex and by combined sexes. The relationships obtained for combined sexes for the entire period concerning the growth in length and weight were: total length-total weight =0.0038L3.172, total length-gutted weight =0.0052L3.059. The relationship total weight-gutted weight was Wt = 15.8112 + 0.8480Wg and the conversion factor was of 1.1524. The growth rate is similar for both sexes but different when based on total weight or gutted weight. The analysis of the condition factor, gonadosomatic index, hepatosomatic index and the monthly distribution of the maturity stages seem to indicate that hake from thePortugueseCoasthas a long spawning season, with three spawning peaks in March, May and August but the start of the spawning season seems independent of the fish length.

International Journal of Tryptophan Research , 2012, DOI: 10.4137/IJTR.S4260
Abstract: Kynurenic acid (KYNA) is an endogenous metabolite of tryptophan. Studies have revealed increased brain KYNA levels in patients with schizophrenia. Prepulse inhibition (PPI) is a behavioral model for sensorimotor gating and found to be reduced in schizophrenia. Previous studies have shown that pharmacologically elevated brain KYNA levels disrupt PPI in the rat. The aim of the present study was to investigate the receptor(s) involved in this effect. Rats were treated with different drugs selectively blocking each of the sites that KYNA antagonizes, namely the glutamate recognition site of the N-methyl-D-aspartate receptor (NMDAR), the α7* nicotinic acetylcholine receptor (α7nAChR) and the glycine site of the NMDAR. Kynurenine (200 mg/kg) was given to replicate the effects of increased levels of KYNA on PPI. In order to block the glutamate recognition site of the NMDAR, CGS 19755 (10 mg/kg) or SDZ 220–581 (2.5 mg/kg) were administered and to antagonize the α7nAChR methyllycaconitine (MLA; 6 mg/kg) was given. L-701,324 (1 and 4 mg/kg) or 4-Chloro-kynurenine (4-Cl-KYN; 25, 50 and 100 mg/kg), a drug in situ converted to 7-Chloro-kynurenic acid, were used to block the glycine-site of the NMDAR. Administration of SDZ 220-581 or CGS 19755 was associated with a robust reduction in PPI, whereas L-701,324, 4-Cl-KYN or MLA failed to alter PPI. Kynurenine increased brain KYNA levels 5-fold and tended to decrease PPI. The present study suggests that neither antagonism of the glycine-site of the NMDA receptor nor antagonism of the α7nAChR disrupts PPI, rather with regard to the effects of KYNA, blockade of the glutamate recognition-site is necessary to reduce PPI.

Studies of Oxide Layers Grown at 260°C on A106 B Carbon Steel in Aqueous Medium with Ethanolamine or Morpholine  [PDF]
Ana Maria Olmedo, Roberto Bordoni
Materials Sciences and Applications (MSA) , 2015, DOI: 10.4236/msa.2015.69080
Abstract: The water chemistry of the secondary coolant in the majority of Nuclear Power Plants is controlled by AVT (All Volatile Treatment), wherein volatile amines are used to maintain the alkaline pH required for minimizing the corrosion of structural materials which one of them is Carbon Steel. In this treatment, ammonia, morpholine and ethanolamine are commonly used as conditioning reagents. In this context, experiments were carried out by exposing carbon steel A106 B samples in a simulated secondary coolant in order to study the nature of the oxide films. The tests were performed in a static autoclave at 260°C using two media: I) hydrazine + morpholine and II) hydrazine + ethanolamine during different exposure periods up to 1020 h. The oxide film characterization was mainly studied using Scanning Electron Microscopy and X-ray diffraction. A chemical descaling procedure was used to obtain the material weight loss (W) of samples, the adherent and released oxide. The XRD analyses, for all exposures studied, showed that magnetite was the corrosion product formed in the films grown in both media. The material weight loss, after descaling, could be fitted by a law of the type W = ktn, up to 1020 h of exposure tested, resulting in n = 0.42, k = 6.24 for films grown in medium I) and n = 0.39, k = 6.08 for films grown in medium II) respectively (W is in mg/dm2 and t in h). The higher corrosion product release measured in the medium with morpholine could be important in power plant operation.
