title: The Use of A Compound Based on Phyllosilicates and Cinnamon Essential Oil for Chicken Broiler’s Litter

description: ABSTRACT The objective of this study was to evaluate the effectiveness of a litter conditioning compound (LCC) based on 98% phyllosilicates (kaolinite) and 2% cinnamon essential oil to be applied on the litter of broiler houses. Animal performance, prevalence of footpad lesions, and litter quality (water activity, pH, and moisture) were evaluated, in addition to the effect on the incidence of Salmonella spp., evaluated by testing shoe-drag swabs, fecal samples, and organs. Twenty-one broiler houses with similar structure and rearing conditions were distributed in a completely randomized design with three treatments and seven replications each, as follows: T0: control, without the use of LCC; T100: application of 100 grams of LCC per m² of litter per week; T200: application of 200 grams of LCC per m² of litter per week. There was no significant effect of treatments on performance variables; however litter pH was lower when 200g/m2 was used in comparison with the control treatment, a result not verified for moisture and water activity (p&gt;0.05). Our findings demonstrated significant reduction in the percentage of footpad lesions in birds that received the LCC (T0: 63.37%; T100: 41.38% and T200: 27.24%). A reduction in the number of positive flocks for Salmonella spp. Was also observed (with overall positivity rates of 17.86%, 12.14%, and 5% for treatments T0, T100, and T200, respectively). It is concluded that the product reduces the incidence of Salmonella spp. and also significantly reduces the incidence of footpad lesions, two important factors for the poultry industry.

title: Presumed cytomegalovirus retinitis late after kidney transplant

description: Abstract Cytomegalovirus (CMV) retinitis is a rare manifestation of CMV invasive disease and potentially threatening to vision in immunocompromised individuals. Clinical suspicion is fundamental since it is an unusual entity with a progressive and often asymptomatic installation over a long period. The authors report a 70-year-old man with diabetic nephropathy who underwent a kidney transplant (KT) in August 2014 with good clinical evolution. No previous CMV infection or episodes of acute rejection were reported. Five years after transplant, he was admitted due to a reduced visual acuity of the left eye with seven days of evolution with associated hyperemia, without exudate. The ophthalmologic evaluation was compatible with acute necrosis of the retina and presumed associated with CMV infection. He had a progressive improvement after ganciclovir initiation. CMV retinitis is one of the most serious ocular complications in immune-suppressed individuals and can lead to irreversible blindness, and because of that, early diagnosis and treatment remains crucial in obtaining the best visual prognosis in affected patients. Secondary prophylaxis with ganciclovir is not consensual, neither is the safety of reintroducing the antimetabolite in these cases.

title: EFFECT OF MERCURY EXPOSURE ON U1-70 KDA PROTEIN EXPRESSION IN EMBRYOS OF BLACK BEAN (Phaseolus vulgaris L.)

description: Exposure to heavy metals has been documented to induce changes in the expression of plant proteins. Phaseolus vulgaris L., represents a great source of nutrition for millions of people, and is the second most important legume crop. The present study aimed to investigate the effects of Hg stress on germination rate and identify the gene expression profiling of U1-70 kDa by using SDS-PAGE analysis. Seeds of black beans (P. vulgaris L.) variety Jamapa were used. The study was performed in the municipality of Guadalupe in Zacatecas, México; August 2009 to 2011. Embryos were exposed to 10 µmol L-1 HgCl2. Expression and detection of U1-70 kDa was affected by mercury. It was possible to amplify the cDNA for U1-70 kDa in all tested samples, there were also found variations in the mRNA of embryos bean seeds for western blot analysis. Mercury does not affect the germination of bean seeds P. vulgaris L.; there is variation in the expression of the U1-70 kDa protein at different hours of exposure to 10 µmol L-1 of mercury. The presence of U1-70 kDa is identified for the first time in early stages of germination of bean seeds P. vulgaris L.

title: Paired kidney donation: are we going beyond reasonable limits in living-donor transplantation?

description: Abstract The growing demand for transplant kidneys requires strategies to increase organ supply and avoid long waiting periods on the list. The increase in the number of transplants from living donors involves the growth in the use of unrelated donors and paired kidney donation. Most of these transplants are performed in the USA, where they already represent, respectively, 34% and 16% of total transplants from living donors. In Latin America, and especially in Brazil, there is no collective enthusiasm for these modalities, either at the request of transplanters or that of the community, with the region's priority being to increase transplants from deceased donors, which growth can be up to three-fold. Concerning transplants from matched donors, the possible conflicting results between donors can generate public challenges and they risk compromise the concepts of equal opportunities for transplant candidates, with the possibility of generating resistance to organ donation, especially in regions with socioeconomic limitations and disparities in access to qualified health care and education. This donation model involves challenging ethical and logistical issues, which are subject to questionings, starting with an act of exchange between two pairs until reaching embarrassing proposals, which can compromise the altruistic character of organ donation, and thus not be universally incorporated.

title: Nomophobia and smartphone addiction: do the variables age and sex explain this relationship?

description: Abstract This study aimed to identify the extent nomophobia explains smartphone addiction, controlling for age and gender effects. Participants were 316 people from the 22 Brazilian states (Mage = 28.1 years), most from Paraíba (38.9%) and Piauí (16.5%), equally distributed between genders. They answered the Nomophobia Questionnaire, the Smartphone Addition Scale and demographic questions. The results demonstrate that the factors of the nomophobia measure explained smartphone addiction, indicating that more nomophobic behavior equates to increased smartphone addiction, especially in the younger participants, there was no difference regarding gender. These findings are discussed according to the literature on adherence to new technologies, revealing the current problem of smartphone addiction in young people.

title: Omphalocele and biliary atresia: chance or causality. A case report

description: ABSTRACT To relate omphalocele and biliary atresia and investigate possible embryological correlations that justify the simultaneous occurrence. A female preterm newborn diagnosed as omphalocele; cesarean delivery, weight 2,500g, 46 XX karyotype. Initially, the newborn remained fasting and on parenteral nutrition, and enteral diet was introduced later, with good acceptance. On the 12th day of life, the newborn presented direct hyperbilirubinemia, increased levels of liver enzymes and fecal acholia, with a presumptive diagnosis of biliary atresia. However, the ultrasound was inconclusive, due to anatomical changes resulting from omphalocele. A surgical approach was chosen on the 37th day of life aiming to confirm diagnosis of biliary atresia and to repair omphalocele. During the surgical procedure, structural alterations compatible with biliary atresia were observed, later confirmed by pathological examination; a hepatoportoenterostomy was performed and the omphalocele was corrected. She evolved well in the postoperative period, with a decrease in direct bilirubin and liver enzymes, as well as resolution of fecal acholia, and was discharged in good clinical condition. This is a bizarre and extremely rare association, but the prognosis may be good when an early diagnosis is made and surgery performed, besides support and clinical management to prevent complications in the perioperative period. Although the pathogenesis of the diseases has not been fully defined yet, there is, to date, no direct relation between them. The association between omphalocele and biliary atresia is extremely uncommon, with only two published cases.

title: FACTORIAL DESIGN FOR THE SYNTHESIS OF ETHYL OLEATE CATALYZED BY NATIVE LIPASE Aspergillus niger.

description: This work reports the use of the Octave, a free computational software, to optimize the experimental design in the synthesis of ethyl oleate from oleic acid and ethanol catalyzed by a native lipase from Aspergillus niger. The central composite factorial design (CCD) was performed with 2 levels and 3 variables (temperature, mass of native A. niger lipase and oleic acid:ethanol molar ratio) in conjunction with response surface methodology (RSM). The results indicate that variable 1 (oleic acid:ethanol molar ratio; X1) and 2 (mass of A. niger lipase, X2), as well as the interaction between them, are statistically significant. The optimal reaction condition was estimated using ANOVA data and the response surface. The experimental results are consistent with those estimated, and thus, ethyl oleate was obtained with conversion (&gt; 90%) using oleic acid and ethanol in a 1:2 molar ratio, A. niger lipase (8,00 mg) and temperature of 45 °C in 6 hours of reaction.

title: From oppressors to oppressed: psychosocial stressors and job satisfaction among correctional officers

description: Abstract In its proposal to analyze the relationship between psychosocial stressors and job satisfaction among correctional officers in the traditional system and Association for Protection and Assistance to Convicts - (APAC), the study included 206 participants, who completed the questionnaires for assessing psychosocial stressors, job satisfaction, and sociodemographic data. Psychometric properties of the instruments were evaluated and hierarchical regression analyses were performed. The stressors explained the variance in job satisfaction levels, regardless of the type of prison system, which also showed explanatory power, indicating higher levels of job satisfaction in the APAC method. Aspects intrinsic to the job itself were predictors of all dimensions of satisfaction, followed by lack of social support and level of responsibility. Satisfaction with management was the most sensitive variable to the stressors addressed. The findings highlight the importance of the psychosocial environment for the workers’ well-being.

title: Spatio-temporal dynamics of surface water quality of two large reservoirs of Brazilian hydroelectric plants

description: ABSTRACT The use of water resources for energy generation, generally, involves the design of artificial dams and reservoirs. The construction of reservoirs may be associated with socio-environmental impacts. The use of statistical techniques and indexes to assess surface water quality data has been an efficient tool for understanding the spatial dynamics of these environments. The work aimed to evaluate the water quality in two large reservoirs and their main tributaries, the Emborcação and Nova Ponte hydroelectric power plants in Minas Gerais. Secondary data were evaluated using the Multivariate Statistical Technique of Cluster Analysis (CA), followed by non-parametric tests, also the Environment Water Quality Index (WQI) and the Trophic State Index (TSI). To support the discussion of the results, the types of land use and occupation in the study area were also analyzed. The results of the CA indicated the separation of the monitoring sites of each reservoir into groups, according to their locations and the type of environment in which they are inserted. The results of the statistical tests suggested a better water quality in the groups formed by stations located in the reservoir and close to it, which have been confirmed by WQI. The results of the WQI indicated the adequacy of the quality of these waters, in relation to the proposed uses for class 2 framing. About the TSI, there was the presence of intermediate primary productivity at acceptable levels. The predominance of land use for agriculture can partially justify the degradation conditions of the water quality watercourses’, especially about the parameters associated with solids and nutrients.
