A materialização da dignidade da pessoa humana e o cumprimento das penas privativas de liberdade

The current research come from need to analyze possibilities to materialize human dignity principle during freedom curtail penalties fullfilment, abreast finding that internal and international regulations dictate this is the way to be tread by Brazilian penitentiary system, however, verily, indignity, assistance missing, overcrownding, crime, in the end, barbarie reigns. The work will analyze two strands in order to effective the mentioned principle: the state responsability optics, such in internal scope, as internationally, abreast historical omission in satisfy Constitution, international treaties and laws; and also indicating penal execution alternative methods adoption as a way, bringing to fore a case study - called "apaqueano" method. With such desideratum will bring, first of all, considerations about consolidation process of human dignity principle, its concept and essential content. Furthermore, will address historical and philosophical evolution of freedom curtail penalties. As it follows, will be done an approach about constitutional and underconstitutional legislation that disciplines penalties fullfiling in Brazil, analyzing their main aspects, emphasizing the possibility to charge Brazilian state for disregarding mentioned standards. Next, will also be started a critical analyzis about international regulations, which forbids diminishing or cruel penalties or treatments, approaching human rights international treaties and conventions ratified by Braziland their incorporation and effectiveness in local Law, emphasizing monitoring forms and country international charging possibility for disregarding international regulations. Lastly, will advance to the real possibility to materialize human dignity principle in penalties fullfiling, based in a case study verification - the APAC (Associação de Proteção e Assistência aos Condenados) called method, analyzing the various theories about penalties grounding, with emphasis in their ressocializing function, as well as traditional penitentiary systems, and the theory adopted by vernacular order, in desideratum to contribute to improve national penitentiary system chaotic situation

Experimental Trypanosoma evansi infection in donkeys: hematological, biochemical and histopathological changes

Cinco jumentos, adultos foram infectados experimentalmente com cepa brasileira de Trypanosoma evansi, isolada de um cão naturalmente infectado, com o intuito de observar as alterações hematológicas, bioquímicas e histopatológicas durante a evolução da enfermidade. O curso da infecção experimental foi de 145 dias. Análise hematológica dos jumentos infectados revelou declínio nos valores de hemoglobina, hematócrito e contagem total de eritrócitos. Notou-se anemia após sucessivos picos de parasitemia. Análise bioquímica indicou aumento dos níveis de índice ictérico, globulinas séricas e diminuição dos valores séricos de albumina e glicose. Todos os jumentos infectados apresentaram aumento do baço e de sua polpa branca, aumento de linfonodos mediastínicos e congestão pulmonar. Meningoencefalite foi o principal achado histopatológico. em algumas áreas do pedículo cerebelar foram observadas desmielinização, além de vacuolização do neurópilo. O estudo mostrou que jumentos infectados com a cepa brasileira do T. evansi desenvolveram doença crônica.

Hepatoprotective treatment attenuates oxidative damages induced by carbon tetrachloride in rats

The present study evaluated the hepatoprotective effect of an N-acetyl or-methionine + choline chloride + caffeine + thiamine hydrochloride + nicotinamide + pyridoxine hydrochloride compound at doses of 0.2, 0.6 and 1.0 mL/kg of b.w., and the assessment was done by the investigation of serum-enzymatic activity, metabolic functions of the liver and histophatological changes in female Wistar rats, which were subjected to experimental intoxication with CCl4. One hundred and nineteen rats were randomly distributed into 17 groups, performing five different treatments, being evaluated seven animals per treatment in four periods: 2, 4, 6 and 8 days after CCl4-induced intoxication. Treated rats with the hepatoprotective medicine (HM) presented a significant reduction in infiltration of inflammatory cells, steatosis, necrosis and liver congestion when compared to non-treated rats (control). Beside these results, the treatment showed a positive effect on circulatory alterations in the intoxicated animals, with reduction of spleen and renal congestion, as well as, promotion of a significant improvement in ALT, AST, LDH, ALP, GGT enzymatic serum activity reduction and in recovering liver function regarding the metabolism of urea, triglycerides and glucose. These findings indicate therapeutic usefulness of the compound when administered at dose 0.6 and 1.0 mL/kg of b.w. in female Wistar rats. (C) 2010 Elsevier GmbH. All rights reserved.

Análise de efluente e histologia da pele, fígado e rim de Pacus (Piaractus mesopotamicus) suplementados com cromo trivalente

The objective of this work was to evaluate the skin, liver and kidney histology of young pacus supplemented in diet with trivalent chromium and to evaluate the residue of chromium in water effluent. Randomised delineation by using factorial scheme 4x2, with four levels of chromium (0, 6, 12, 18 mg/L), two stocking densities (4 and 20 kg/m(3)), and four repetitions were used. Pacus with 100 g were used, for 90 days. An increase of the number of mucus cells and club cells in the epidermis of the pacus supplemented with 18 chromium mg/kg was observed in any stocking density. The same effect was observed in the liver, and in the highest density (20 kg/m(3)) the alterations already occurred at the level of 6 mg/kg with the inclusion of chromium, initially with congestion of sinusoids and getting worse at the level of 18 mg/kg with necrosis. The kidney didn't present visible morphologic alterations when supplemented and submitted to the stocking densities. The concentration of chromium in the effluent of pacus was 3.27 mu g/L in the higher level of supplementation (18 mg/L). In conclusion the level of 18 supplement mg/kg was not shown beneficial to the growth of pacus and the stocking density, due to the possible stress, accelerated the alteration histology process of tissues.

Piscinoodinium pillulare (Schäperclaus, 1954) Lom, 1981 (Dinoflagellida) infection in cultivated freshwater fish from the Northeast region of São Paulo State, Brazil: parasitological and pathological aspects

O Centro de Aqüicultura, Unesp, Jaboticabal, SP, Brasil, recebeu peixes para diagnose, os quais apresentavam aglomeração nas bordas dos viveiros e na entrada da água. Dos 194 casos diagnosticados, 53 apresentavam estruturas brancas circulares ou ovais, imóveis, medindo 162 mm de diâmetro, identificadas como o dinoflagelado Piscinoodinium pillulare. em 34 casos, os parasitos estavam presentes nas brânquias, em 2 casos, no corpo e em 9 casos, em ambos. Dos 53 casos observados, 31 eram o híbrido tambacu; 7, o Piaractus mesopotamicus; 6, o Colossoma macropomum; 5, o Leporinus macrocephalus; 3, o Oreochromis niloticus; e 1, o Prochilodus lineatus. Os peixes apresentaram aumento da produção de muco no corpo e nas brânquias e equimoses no pedúnculo caudal e nos opérculos. As brânquias também apresentaram palidez, congestão e petéquias. A histopatologia revelou a presença de grande número de trofontes situados entre as lamelas secundárias, fixados ou não ao epitélio. As lamelas primárias mostraram hemorragias intersticiais, severa hiperplasia do epitélio e das células caliciformes e infiltrado inflamatório. O presente trabalho é o primeiro relato de P. pillulare no Brasil e enfatiza a importância dos dinoflagelados, que causaram significativas perdas econômicas entre 1995 e 1997.

Aspectos clínicos e patológicos em frangos de corte (Gallus gallus domesticus) infectados experimentalmente com oocistos esporulados de Eimeria acervulina Tyzzer, 1929

No presente estudo, sinais clínicos e alterações patológicas foram avaliados por 30 dias em frangos de corte, linhagem Cobb, machos, com dez dias de idade, infectados com Eimeria acervulina. Foram utilizados 192 animais distribuídos em 3 grupos: grupo A inoculado com 1x10(6) oocistos esporulados; grupo B inoculado com 1x10(5) oocistos esporulados; grupo C inoculado com água destilada. Os sinais clínicos observados foram anorexia, diarréia e apatia. As alterações patológicas macroscópicas observadas foram: enterite, hiperemia seguido de congestão intestinal, excesso de exsudato mucoso no lúmen do intestino delgado, palidez e desidratação muscular, alto acúmulo de bile na vesícula biliar e deposição de gordura hepática. A atrofia de vilosidades e alta presença de células inflamatórias foram as alterações microscópicas observadas no epitélio intestinal. Na análise histopatológica do fígado observaram-se infiltrados inflamatórios e deposição de gordura. Os resultados demonstraram que frangos de corte infectados experimentalmente com E. acervulina apresentam progressivas lesões intestinais de intensidade variável e que essas anormalidades são as principais causas de redução no desenvolvimento da ave.

Acurácia dos indicadores clínicos do diagnóstico de enfermagem volume de líquidos excessivo em pacientes submetidos à hemodiálise

Trasnversal study, with the objective of evaluating the accuracy of clinical indicators of nursing diagnosis excessive fluid volume in patients undergoing hemodialysis. The study occurred in two stages, the first consisted of the evaluation of the diagnostic indicators in study; and the second, the diagnostic inference conducted by nurse diagnosticians. The first stage occurred from december 2012 to april 2013, in a University Hospital and a Hemodialysis Clinic in Northeastern of Brazil, with a sample of 100 chronic renal failure patients on hemodialysis. The data were selected through an interview form and a physical examination, organized into spreadsheets and analyzed as to the presence or absence of the indicators of diagnosis excessive fluid volume. In the second step, the spreadsheets were sent to three nurses diagnosticians, who judged the presence or absence of diagnosis in the clientele searched. This step was conducted from july to september 2013. For analysis of the data, we used descriptive and inferential statistics. In the descriptive analysis, we used measures of central tendency and dispersion. In inferential analysis, we used the tests Chi- square, Fisher and prevalence ratios. The accuracy of the clinical indicators pertaining to the diagnosis were measured as to the specificity, sensitivity, predictive values, likelihood ratios and Diagnostic Odds Ratio. Also developed a logistic regression. The results were organized in tables and discussed with literature. This study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte, with Presentation Certificate for Ethics Appreciation nº 08696212.7.0000.5537. The results revealed that the diagnosis studied was present in 82% of patients. The characteristics with prevalence above 50 % that stood out were: azotemia, decreased hematocrit, electrolyte imbalance, intake exceeds output, anxiety, edema, decreased hemoglobin, oliguria and blood pressure changes. Eight defining characteristics were presented statistically significant association with the nursing diagnosis investigated: pulmonary congestion, intake exceeds output, electrolytes imbalance, jugular vein distension, edema, weight gain over short period of time, agitation and adventitious breath sounds. Among these, the 10 characteristics which showed higher prevalence ratios were: edema and weight gain over short period of time. The features with the highest sensitivity were edema, electrolytes imbalance and intake exceeds output and the standing out with greater specificity were: anasarca, weight gain over short period of time, change in respiratory pattern, adventitious breath sounds, pulmonary congestion, agitation and jugular vein distension. The indicators jugular vein distension, electrolytes imbalance, intake exceeds output, increased central venous pressure and edema, together, were identified in the logistic regression model as the most significant predictors. It is concluded that the identification of accurate clinical indicators allow a good prediction of the nursing diagnosis of excessive fluid volume in patients undergoing hemodialysis in order to assist the nurse in the inference process, which will contribute to the success of patient care. In addition, nurses will consider for diagnostic inference not only his clinical experience, but also scientific evidence of the occurrence of excessive fluid volume, contributing to the control of volemia in these patients

Crescimento de filmes nanométricos monocristalinos de Fe/MgO(100) por "SPUTTERING" DC

The research behind this master dissertation started with the installation of a DC sputtering system, from its first stage, the adaptation of a refrigerating system, passing by the introduction of a heating system for the chamber using a thermal belt, until the deposition of a series of Fe/MgO(100) single crystal nanometric film samples. The deposition rates of some materials such as Fe, Py and Cu were investigated through an Atomic Force Microscope (AFM). For the single crystal samples, five of them have the same growth parameters and a thickness of 250Å, except for the temperature, which varies from fifty degrees from one to another, from 100ºC to 300ºC. Three other samples also have the same deposition parameters and a temperature of 300ºC, but with thickness of 62,5Å, 150Å, and 250Å. Magneto-optical Kerr Effect (MOKE) of the magnetic curves measurements and Ferromagnetic Resonance (FMR) were made to in order to study the influence of the temperature and thickness on the sample s magnetic properties. In the present dissertation we discuss such techniques, and the experimental results are interpreted using phenomenological models, by simulation, and discussed from a physical point of view, taking into account the system s free magnetic energy terms. The results show the growth of the cubic anisotropy field (Hac) as the sample s deposition temperature increases, presenting an asymptotic behavior, similar to the characteristic charging curve of a capacitor in a RC circuit. A similar behavior was also observed for the Hac due to the increase in the samples thicknesses. The 250˚A sample, growth at 300°C, presented a Hac field close to the Fe bulk value

Analysis of the accumulated energy by thermal stratification of liquid inside storage tanks with porous layers

A mathematical model was developed in order to study the behavior of thermal stratification of liquid in a typical storage tank with porous medium. The model employs a transient stream function-vorticity formulation to predict the development of stream function and temperature fields in a charging process. Parameters analyzed include Biot, Darcy, Reynolds and Richardson numbers, position, and the thickness of the porous medium. The results show the influence of these physical parameters that should be considered for a good design of storage tanks with thermal stratification.

High laryngeal mask airway pressures resulting from nitrous oxide do not increase pharyngeal mucosal injury in dogs

Purpose: During general anesthesia, nitrous oxide (N2O) diffuses rapidly into the air-filled laryngeal mask airway (LMA) cuff, increasing intracuff pressure. There is no clear correlation between LMA intracuff pressure and pressure on the pharynx. We have studied the effects of high LMA intracuff pressures secondary to N2O on the pharyngeal mucosa of dogs.Methods: Sixteen mongrel dogs were randomly allocated to two groups: G1 (intracuff volume, 30 mL; n = 8) breathed a mixture of O-2 (1 L.min(-1)) and air (1 L.min(-1)) and G2 (intracuff volume, 30 mL; n=8) a mixture of O-2 (1 L.min(-1)) and N2O (1 L.min(-1)). Anesthesia was induced and maintained with pentobarbitone. LMA cuff pressure was measured at zero (control), 30, 60, 90 and 120 min after #4 LMA insertion. The dogs were sacrificed, and biopsy specimens from seven predetermined areas of the pharynx in contact with the LMA cuff were collected for light (LM) and scanning electron microscopic (SEM) examination by a blinded observer.Results: LMA intracuff pressure decreased with time in G1 (P < 0.001) and increased in G2 (P < 0.001). There was a significant difference between the groups (P < 0.001). In both groups, the LM study showed a normal epithelium covering the pharyngeal mucosa and mild congestion in the subepithelial layer There were no differences between the groups (P > 0.10) or among the areas sampled (P > 0.05). In both groups, the SEM study showed a normal pharyngeal mucosa with mild superficial desquamation. Few specimens in G1 and G2 showed more intense epithelial desquamation.Conclusion: High LMA intracuff pressures produced by N2O do not increase pharyngeal mucosal injury in dogs.

Glibenclamide effects on renal function and histology after acute hemorrhage in rats under sevoflurane anesthesia

Introduction. Hypovolemia from hemorrhage evokes protective compensatory reactions, such as the renin-angiotensin system, which interferes in the clearance function and can lead to ischemia. This study was designed to evaluate the effects of glibenclamide, a K-ATP(+) channel blocker, on renal function and histology in rats in a state of hemorrhagic shock under sevoflurane anesthesia. Material and Methods. Twenty Wistar rats were randomized into two groups of 10 animals each (G1 and G2), only one of which (G2) received intravenous glibenclamide (1 mu g.g(-1)), 60 min before bleeding was begun. Both groups were anesthetized with sevoflurane and kept on spontaneous respiration with oxygen-air, while being bled of 30% of volemia in three stages with 10 min intervals. There was an evaluation of renal function-sodium para-aminohippurate and iothalamate clearances, filtration fraction, renal blood flow, renal vascular resistance-and renal histology. Renal function attributes were evaluated at three moments: M1 and M2, coinciding with the first and third stages of bleeding; and M3, 30 min after M2, when the animals were subjected to bilateral nephrectomy before being sacrificed. Results. Significant differences were found in para-aminohippurate clearance, G1 < G2, and higher renal vascular resistance values were observed in G1. Histological examination showed the greater vulnerability of kidneys exposed to sevoflurane alone (G1) with higher scores of vascular and tubular dilatation. There were vascular congestion and tubular vacuolization only in G1. Necrosis and signs of tubular regeneration did not differ in both groups. Conclusion. Treatment with glibenclamide attenuated acutely the renal histological changes after hemorrhage in rats under sevoflurane anesthesia.
