Abstract:
Didymella bryoniae (anamorph Phoma cucurbitacearum) is the causal agent of gummy stem blight, although other Phoma species are often isolated from cucurbit plants exhibiting symptoms of the disease. The molecular and phylogenetic relationships between D. bryoniae and these Phoma species are unknown. Isolates of D. bryoniae and Phoma obtained from cucurbits grown at various geographical locations in the United States were subjected to random amplified polymorphic DNA (RAPD) analysis and internal transcribed spacer (ITS) sequence analysis (ITS-1 and ITS-2) to determine the molecular and phylogenetic relationships within and between these fungi. Using RAPD fingerprinting, 59 isolates were placed into four phylogenetic groups, designated RAPD group (RG) I, RG II, RG III, and RG IV. D. bryoniae isolates clustered in either RG I (33 isolates), RG II (12 isolates), or RG IV (one isolate), whereas all 13 Phoma isolates clustered to RG III. There was greater than 99% sequence identity in the ITS-1 and ITS-2 regions between isolates in RG I and RG II, whereas isolates in RG III, P. medicaginis ATCC 64481, and P. exigua ATCC 14728 clustered separately. On muskmelon seedlings, a subset of RG I isolates were highly virulent (mean disease severity was 71%), RG II and RG IV isolates were slightly virulent (mean disease severity was 4%), and RG III isolates were nonpathogenic (disease severity was 0% for all isolates). The ITS sequences indicate that RG I and RG II are both D. bryoniae, but RAPD fingerprints and pathogenicity indicate that they represent two different molecular and virulence subgroups.

Abstract:
Radix Glycyrrhizae (RG)-Radix Euphorbiae Pekinensis (REP) is a representative incompatible herbal pair of Eighteen Incompatible Medicaments (EIM) and has been disputed in clinical application for a long time. The present study was performed with the Madin-Darby canine kidney (MDCK) cell line using cell cytotoxicity assay, apoptosis detection, cell cycle measurement, reactive oxygen species (ROS) determination, and high content analysis (HCA) in combination with high-performance liquid chromatography (HPLC) fingerprint comparison to clarify whether RG and REP can be concomitantly used from the perspective of cytotoxicity, investigate the major correlated compounds, and elucidate the underlying mechanisms. The results showed that the toxicity of REP could be significantly enhanced through its concomitant use with RG in the ratio of 1 : 1, and this increased toxicity could be weakened with the further increased proportion of RG. 3,3′-di-O-methylellagic acid-4′-O-β-D-xylopyranoside (DEAX) and 3,3′-di-O-methylellagic acid (DEA) were shown to be mainly responsible for the toxicity induced by concomitant use of REP and RG. Both RG-REP decoctions and the above two compounds boosted cell apoptosis, cellular morphological change, ROS accumulation, and mitochondrial membrane potential (MMP) disruption. In conclusion, the incompatible use of RG and REP is conditionally established because of the bidirectional regulatory effect of RG, and the major compounds responsible for RG-REP incompatibility are DEAX and DEA, which result in toxicity through activation of mitochondria-dependent apoptosis induced by increased ROS production. This study provided a basis for understanding the incompatible use of RG and REP and the EIM theory.

Abstract:
Diaphragm abnormalities in aging or chronic diseases include impaired mitochondrial respiration and H2O2 emission, which can be measured using saponin-permeabilized muscle fibers. Mouse diaphragm presents a challenge for isolation of fibers due to relatively high abundance of connective tissue in healthy muscle that is exacerbated in disease states. We tested a new approach to process mouse diaphragm for assessment of intact mitochondria respiration and ROS emission in saponin-permeabilized fibers. We used the red gastrocnemius (RG) as “standard” limb muscle. Markers of mitochondrial content were two– to fourfold higher in diaphragm (Dia) than in RG ( P < 0.05). Maximal O2 consumption ( JO2: pmol·s−1·mg−1) in Dia was higher with glutamate, malate, and succinate (Dia 399 ± 127, RG 148 ± 60; P < 0.05) and palmitoyl-CoA + carnitine (Dia 15 ± 5, RG 7 ± 1; P < 0.05) than in RG, but not different between muscles when JO2 was normalized to citrate synthase activity. Absolute JO2 for Dia was two– to fourfold higher than reported in previous studies. Mitochondrial JH2O2 was higher in Dia than in RG ( P < 0.05), but lower in Dia than in RG when JH2O2 was normalized to citrate synthase activity. Our findings are consistent with an optimized diaphragm preparation for assessment of intact mitochondria in permeabilized fiber bundles. The data also suggest that higher mitochondrial content potentially makes the diaphragm more susceptible to “mitochondrial onset” myopathy. Overall, the new approach will facilitate testing and understanding of diaphragm mitochondrial function in mouse models that are used to advance biomedical research and human health.

Abstract:
Reverse gyrases (RGs) are the only topoisomerases capable of generating positive supercoils in DNA. Members of the type IA family, they do so by generating a single-strand break in substrate DNA and then manipulating the two single strands to generate positive topology. Here, we use single-molecule experimentation to reveal the obligatory succession of steps that make up the catalytic cycle of RG. In the initial state, RG binds to DNA and unwinds ∼2 turns of the double helix in an ATP-independent fashion. Upon nucleotide binding, RG then rewinds ∼1 turn of DNA. Nucleotide hydrolysis and/or product release leads to an increase of 2 units of DNA writhe and resetting of the enzyme, for a net change of topology of +1 turn per cycle. Final dissociation of RG from DNA results in rewinding of the 2 turns of DNA that were initially disrupted. These results show how tight coupling of the helicase and topoisomerase activities allows for induction of positive supercoiling despite opposing torque.

Abstract:
The sympathetic nervous system has greater influence on vascular resistance in low-oxidative, fast-twitch skeletal muscle than in high-oxidative skeletal muscle (17). The purpose of this study was to test the hypothesis that arterioles isolated from low-oxidative, fast-twitch skeletal muscle [the white portion of gastrocnemius (WG)] possess greater responsiveness to adrenergic constriction than arterioles isolated from high-oxidative skeletal muscle [red portion of the gastrocnemius muscle (RG) and diaphragm (Dia)]. Second-order arterioles (2As) were isolated from WG, RG, and Dia of rats and reactivity examined in vitro. Results reveal that Dia 2As constrict less to norepinephrine (NE) (10−9 to 10 −4 M) than 2As from RG and WG, which exhibited similar NE-induced constrictions. This difference was not endothelium dependent, because responses of denuded 2As were similar to those of intact arterioles. The blunted NE-induced constrictor response of Dia 2As appears to be the result of differences in α1-receptor effects because 1) arterioles from Dia also responded less to selective α1-receptor stimulation with phenylephrine than RG and WG arterioles; 2) arterioles from Dia, RG, and WG dilated similarly to isoproterenol (10−9 to 10−4 M) and did not respond to selective α2-receptor stimulation with UK-14304; and 3) endothelin-1 produced similar constriction in 2As from Dia, RG, and WG. We conclude that differences in oxidative capacity and/or fiber type composition of muscle tissue do not explain different NE responsiveness of Dia 2As compared with 2As from gastrocnemius muscle. Differences in α1-adrenergic constrictor responsiveness among arterioles in skeletal muscle may contribute to nonuniform muscle blood flow responses observed during exercise and serve to maintain blood flow to Dia during exercise-induced increases in sympathetic nerve activity.

Abstract:
Red ginseng has been reported to elicit various therapeutic effects relevant to cancer, diabetes, neurodegenerative diseases, and inflammatory diseases. However, the effect of red ginseng on exercise endurance and skeletal muscle function remains unclear. Herein, we sought to investigate whether red ginseng could affect exercise endurance and examined its molecular mechanism. Mice were fed with red ginseng extract (RG) and undertook swimming exercises to determine the time to exhaustion. Animals fed with RG had significantly longer swimming endurance. RG treatment was also observed to enhance ATP production levels in myoblasts. RG increased mRNA expressions of mitochondrial biogenesis regulators, NRF-1, TFAM, and PGC-1α, which was accompanied by an elevation in mitochondrial DNA, suggesting an enhancement in mitochondrial energy-generating capacity. Importantly, RG treatment induced phosphorylation of p38 and AMPK and upregulated PGC1α expression in both myoblasts and in vivo muscle tissue. In addition, RG treatment also stimulated C2C12 myogenic differentiation. Our findings show that red ginseng improves exercise endurance, suggesting that it may have applications in supporting skeletal muscle function and exercise performance.

Abstract:
Ribonucleoside triphosphates are often incorporated into genomic DNA during DNA replication. The accumulation of unrepaired ribonucleotides is associated with genomic instability, which is mediated by DNA topoisomerase 1 (Top1) processing of embedded ribonucleotides. The cleavage initiated by Top1 at the site of a ribonucleotide leads to the formation of a Top1-DNA cleavage complex (Top1cc), occasionally resulting in a DNA double-strand break (DSB). In humans, tyrosyl-DNA phosphodiesterases (TDPs) are essential repair enzymes that resolve the trapped Top1cc followed by downstream repair factors. However, there is limited cellular evidence of the involvement of TDPs in the processing of incorporated ribonucleotides in mammals. We assessed the role of TDPs in mutagenesis induced by a single ribonucleotide embedded into DNA. A supF shuttle vector site-specifically containing a single riboguanosine (rG) was introduced into the human lymphoblastoid TK6 cell line and its TDP1-, TDP2-, and TDP1/TDP2-deficient derivatives. TDP1 and TDP2 insufficiency remarkably decreased the mutant frequency caused by an embedded rG. The ratio of large deletion mutations induced by rG was also substantially lower in TDP1/TDP2-deficient cells than wild-type cells. Furthermore, the disruption of TDPs reduced the length of rG-mediated large deletion mutations. The recovery ratio of the propagated plasmid was also increased in TDP1/TDP2-deficient cells after the transfection of the shuttle vector containing rG. The results suggest that TDPs-mediated ribonucleotide processing cascade leads to unfavorable consequences, whereas in the absence of these repair factors, a more error-free processing pathway might function to suppress the ribonucleotide-induced mutagenesis. Furthermore, base substitution mutations at sites outside the position of rG were detected in the supF gene via a TDPs-independent mechanism. Overall, we provide new insights into the mechanism of mutagenesis induced by an embedded ribonucleotide in mammalian cells, which may lead to the fatal phenotype in the ribonucleotide excision repair deficiency.

Abstract:
ABSTRACT Plant cell wall degradation is a premier event when Bacillus subtilis, a typical saprophytic bacterium, invades plants. Here we show the degradation system of rhamnogalacturonan type I (RG-I), a component of pectin from the plant cell wall, in B. subtilis strain 168. Strain 168 cells showed a significant growth on plant cell wall polysaccharides such as pectin, polygalacturonan, and RG-I as a carbon source. DNA microarray analysis indicated that three gene clusters (yesOPQRSTUVWXYZ, ytePQRST, and ybcMOPST-ybdABDE) are inducibly expressed in strain 168 cells grown on RG-I. Cells of an industrially important bacterium, B. subtilis strain natto, fermenting soybeans also express the gene cluster including the yes series during the assimilation of soybean used as a carbon source. Among proteins encoded in the yes cluster, YesW and YesX were found to be novel types of RG lyases releasing disaccharide from RG-I. Genetic and enzymatic properties of YesW and YesX suggest that strain 168 cells secrete YesW, which catalyzes the initial cleavage of the RG-I main chain, and the resultant oligosaccharides are converted to disaccharides through the extracellular exotype YesX reaction. The disaccharide is finally degraded into its constituent monosaccharides through the reaction of intracellular unsaturated galacturonyl hydrolases YesR and YteR. This enzymatic route for RG-I degradation in strain 168 differs significantly from that in plant-pathogenic fungus Aspergillus aculeatus. This is, to our knowledge, the first report on the bacterial system for complete RG-I main chain degradation.

Objetivou-se com este trabalho a obtenção de modelos para a estimativa do saldo de radiação (Q*) a partir da radiação solar global incidente (Rg) sobre dosseis de plantas de girassol. Os experimentos foram conduzidos na área experimental da Universidade Federal de Santa Maria, nos anos de 2007, 2008 e 2009. O Q* foi medido com saldos radiômetros instalados acima das plantas e a Rg em estações meteorológicas automáticas. Para fins de cálculo foram efetuadas as somas diárias de Q* e de Rg, obtendo-se a relação entre Q* e Rg para cada dia. Obtiveram-se, então, modelos com elevado coeficiente de determinação e baixo RQME no teste entre valores medidos e estimados de um banco de dados independente, indicando precisão na estimativa do saldo de radiação em dosseis de girassol, independendo da época de cultivo no ano. A função linear geral obtida com dados de diferentes épocas de cultivo foi: Q* = 0,5285 Rg (R² = 0,95), que no teste apresentou RQME = 1,04 MJ m-2 d-1. Conclui-se que o saldo de radiação (Q*) pode ser estimado utilizando-se a radiação solar global medida em estações automáticas, com precisão suficiente para os diferentes fins na agrometeorologia do girassol.

Abstract:
The hyperemic response in exercising skeletal muscle is dependent on muscle fiber-type composition and fiber recruitment patterns, but the vascular control mechanisms producing exercise hyperemia in skeletal muscle remain poorly understood. The purpose of this study was to test the hypothesis that arterioles from white, low-oxidative skeletal muscle are less responsive to adenosine-induced dilation than are arterioles from diaphragm (Dia) and red, high-oxidative skeletal muscle. Second-order arterioles (2As) were isolated from the white portion of gastrocnemius muscle (WG; low-oxidative, fast-twitch muscle tissue) and two types of high-oxidative skeletal muscle [Dia and red portion of gastrocnemius muscle (RG)] of rats. Results reveal that 2As from all three types of muscle dilated in response to the endothelium-dependent dilator acetylcholine (WG: 48 ± 3%, Dia: 51 ± 3%, RG: 74 ± 3%). In contrast, adenosine dilated only 2As from WG (48 ± 4%) and Dia (46 ± 5%) but not those from RG (5 ± 5%). Thus adenosine-induced dilator responses differed among 2As of these different types of muscle tissue. However, the results do not support our hypothesis because 2As from Dia and WG dilated in response to adenosine, whereas 2As from RG did not. We conclude that the adenosine responsiveness of 2As from rat skeletal muscle cannot be predicted only by the fiber-type composition or oxidative capacity of the skeletal muscle tissue wherein the arteriole lies.

The transplantation of organs and tissues presents itself as an important therapeutic option, both from a medical standpoint, the social or economic. Thus, the identification of variables that can interfere in the effectiveness of organs and tissues donation for transplantation needs to be investigated adequately, because it stands before increasing index of chronic and degenerative diseases in the population, what makes the waiting list for transplantation grow disproportionately and patients come to death without the opportunity of realization the treatment due to a lack of donors. In this context, has defined as objective of this study evaluate the factors associated with the effectiveness of organs and tissues donation for transplantation. It is a evaluative research, quantitative, prospective, with longitudinal design, developed at Central of Catchment, Notification and organ donation for transplant, Organ Procurement Organization and in six accredited hospitals to collect and transplantation of organs and tissues, in Natal/RN, between august 2010 and february 2011, after the approval of the Research Ethics Committee, under No. 414/10 and CAAE 007.0.294.000-10. The probabilistic sample without replacement was composed of 65 potential donors. It was used as an instrument of data collection a structured script non-participant observation of checklist type. Data were analyzed using descriptive statistics and presented in tables, charts, graphs and figures. For this, was used Microsoft Excel 2007 and statistical program SPSS version 20.0. To check the level of significance was chosen by applying the chi-square test (χ2) and Mann Whitney and caselas for less than five, it is considered the Fisher exact test. It was adopted as the significance level p-value <0.05. Among the surveyed it was observed that most of the individuals were male (50,8%), in the age group 45 years (53,8%), mean age of 42,3 years, minimum 5 and maximum 73 years (? 17,32 years). Single / widowers / divorced (56,9%), with up to completed elementary school (60,0%) in the exercise of professional activity (86,2%), catholic (83,1%) and residents in metropolitan region of Natal (52,3%). Was obtained donation effectiveness of 27,7%. There was no statistical significance between structure and effectiveness of the donation, but were observed inadequacies in physical resources (36,9%), materials (30,8%), organizational structure (29,2%) and human resources (18,5%). In the process, the maintenance phase (p= 0.004), diagnosis of brain death (p= 0.032), family interview (p≤ 0.001) and documentation (p= 0.001) presented statistical significance with effectiveness. Thus, it is accepts the alternative hypothesis of the study, in which is evidenced that the adequacy of the factors related to structure and process is associated to effectiveness of organs and tissues donation for transplantation. In this way, the effectiveness of organ and tissue donation ends in an essential way the rapidity and accuracy with which the donation process is conducted, requiring appropriate structure, with appropriate physical and material resources and skilled human resources to optimize the reduction of time and the suffering of those waiting for an organ or tissue transplant queued in Brazil
O transplante de ?rg?os e tecidos apresenta-se como importante op??o terap?utica, tanto do ponto de vista m?dico, quanto social ou econ?mico. Assim, a identifica??o das vari?veis que podem interferir na efetividade da doa??o de ?rg?os e tecidos para transplante precisa ser investigada de maneira adequada, pois se est? diante de crescente ?ndice de doen?as cr?nicas e degenerativas na popula??o, que faz com que a lista de espera para transplante aumente desproporcionalmente e os pacientes chegam ao ?bito sem a oportunidade de realiza??o do tratamento devido ao d?ficit de doadores. Nesse contexto, definiu-se como objetivo deste estudo avaliar os fatores associados ? efetividade da doa??o de ?rg?os e tecidos para transplantes. Trata-se de pesquisa avaliativa, quantitativa, prospectiva, com delineamento longitudinal, desenvolvida na Central de Capta??o, Notifica??o e Doa??o de ?rg?os para transplantes, Organiza??o de Procura de ?rg?os e em seis unidades hospitalares credenciadas para capta??o e transplante de ?rg?os e tecidos, em Natal/RN, entre agosto de 2010 e fevereiro de 2011, ap?s a aprova??o do projeto de pesquisa pelo Comit? de ?tica em Pesquisa, CAAE 007.0.294.000-10. A amostra probabil?stica sem reposi??o foi composta de 65 potenciais doadores. Utilizou-se como instrumento de coleta de dados um roteiro estruturado de observa??o n?o participante do tipo checklist. Os dados foram analisados por meio da estat?stica descritiva e apresentados em forma de tabelas, quadros, gr?ficos e figuras. Para tanto, utilizou-se o Microsoft Excel 2007 e o Programa Estat?stico SPSS vers?o 20.0. Para verificar o n?vel de signific?ncia optou-se pela aplica??o dos testes Qui-quadrado (χ2) e Mann Whitney e, para as caselas inferiores a cinco, considerou-se o teste exato de Fisher. Adotou-se como n?vel de signific?ncia p-valor <0,05. Entre os pesquisados observou-se que a maior parte dos indiv?duos era do sexo masculino (50,8%), na faixa et?ria at? 45 anos (53,8%), com m?dia de idade de 42,3 anos, m?nimo de cinco e m?ximo de 73 anos (? 17,32 anos). Solteiros/vi?vos/divorciados (56,9%), com at? o ensino fundamental completo (60,0%), em exerc?cio de atividade profissional (86,2%), cat?licos (83,1%) e residentes na regi?o metropolitana de Natal (52,3%). Obteve-se efetividade de doa??o de 27,7%. N?o ocorreu signific?ncia estat?stica entre a estrutura e a efetividade da doa??o, por?m observaram-se inadequa??es nos recursos f?sicos (36,9%), materiais (30,8%), estrutura organizacional (29,2%) e recursos humanos (18,5%). No processo, as fases de manuten??o (p=0,004), diagn?stico de morte encef?lica (p=0,032), entrevista familiar (p≤ 0,001) e documenta??o (p= 0,001) apresentaram signific?ncia estat?stica com a efetividade. Assim, se aceita a hip?tese alternativa do estudo, na qual se evidencia que a adequa??o dos fatores relacionados ? estrutura e processo est? associada ? efetividade da doa??o de ?rg?os e tecidos para transplantes. Desse modo, a efetividade da doa??o de ?rg?os e tecidos encerra de forma imprescind?vel a rapidez e a precis?o com que o processo de doa??o se conduz, requerendo estrutura adequada, com recursos f?sicos e materiais apropriados e recursos humanos capacitados, para otimizar a diminui??o do tempo e do sofrimento daqueles que aguardam um ?rg?o ou tecido na fila do transplante no Brasil

A disserta??o visou abordar os procedimentos de transplanta??o humana, especificamente a tutela penal relativa ao com?rcio de ?rg?os humanos que tem sido dispensada n?o s? pelo legislador p?trio (Lei 9.434/97), como tamb?m em rela??o ao direito comparado a esta revolucion?ria t?cnica. Tal objetivo foi desenvolvido atrav?s de an?lise eminentemente interdisciplinar, com a abordagem de elementos da hist?ria das id?ias, psiquiatria, filosofia, etnografia, bio?tica e direito. Primeiramente buscou-se investigar a transi??o das vis?es de corpo na modernidade e contemporaneidade: indo desde uma id?ia de sacralidade at? a de profana??o. Ap?s, buscou-se, al?m da realiza??o de an?lise hist?rico-comparativa dos principais avan?os cient?ficos na ?rea com a evolu??o legislativa, principalmente em nosso pa?s, a defini??o de conceitos relacionados ? tem?tica, como o de transplante, suas modalidades e a pol?mica relativa a morte encef?lica. A quest?o de escassez demonstrou-se essencial ? discuss?o, j? que ensejadora de um dos mais debatidos e controversos temas relativos aos transplantes de ?rg?o na atualidade: o com?rcio de ?rg?os humanos. Ap?s discuss?o de casos documentados sobre a pr?tica, foi realizada a confronta??o entre os argumentos favor?veis e contr?rios, chegando-se ? conclus?o de que uma an?lise ? luz da dignidade humana e da ?tica da alteridade ? suficiente para recha?ar a disposi??o remunerada de ?rg?os humanos. Sob a ?tica dos bens jur?dicos envolvidos e do consentimento do ofendido, a conclus?o n?o ? outra. Por ?ltimo atrav?s de pesquisa de campo em que foram entrevistadas 450 pessoas, evidenciou-se a avers?o majorit?ria ao com?rcio de ?rg?os, fundada em um crit?rio moral, em tr?s grupos diferentes (profissionais e acad?micos de Medicina e outras ci?ncias da sa?de; profissionais e acad?micos do Direito e comunidade em geral). O desejo de salvar vidas precisa estar em conson?ncia com o necess?rio respeito ? dignidade humana.

This study aimed at examining the representation and the level of knowledge as well as getting acquainted whether there had been significant divergence among three social groups of 3rd year Law students, 7th period Medical students at UFPB and a group of people from the Catholic Church in vila dos pescadores in Jo?o Pessoa - about organ donation, transplant law and ethical issues that raise questions. In order to accomplish the qualitative analysis, Bardin?s content analysis technique was applied in conjunction with the Chisquare test which was applied with significance level of 5% to quantitative data. The data revealed that most informants agree with organ donation, Although they are not acquainted with the law of transplants, and with the lack of confidence in the single list of recipients. The problem is that there is an encouragement to trades with organs and the possibility of any person legally authorized to donate organs in life. The statistically significant difference was observed in only two questions, ie, in response to the confidence in the diagnosis of brain death: 64% of 7th period Medical students at UFPB trust this diagnosis versus 12% of the evangelizing group of vila dos pescadores. The other difference refers to the answer about the confidence in the single list of recipients: 36% of the 7th period Medical students of UFPB said to trust the list versus 12% of the 3rd law students of UFPB. This is was a multidisciplinary study with Involvement of lawyers and doctors
O presente estudo teve por objetivo analisar a representa??o, o n?vel de conhecimento, bem como saber se existia diverg?ncia significativa entre tr?s grupos sociais estudantes de direito do 3? ano e de medicina do 7? per?odo da UFPB e um grupo de pessoas da igreja cat?lica na vila dos pescadores em Jo?o Pessoa-PB sobre a doa??o de ?rg?os, lei dos transplantes e temas que suscitam questionamentos ?ticos. Aplicou-se a t?cnica de an?lise de conte?do de Bardin para a an?lise qualitativa e o teste Qui-quadrado com n?vel de signific?ncia de 5% para os dados quantitativos. Os dados mostraram que a maioria dos entrevistados ? favor?vel a doa??o de ?rg?os, que n?o conhece a lei de transplantes, como tamb?m n?o confia na lista ?nica de receptores. E que h? um favorecimento ao com?rcio de ?rg?os, a possibilidade de qualquer pessoa autorizada judicialmente ser doador de ?rg?os em vida. A diferen?a estatisticamente significativa s? foi observada em dois questionamentos, ou seja, na resposta sobre a confian?a no diagn?stico de morte encef?lica: 64% dos estudantes de medicina do 7? per?odo da UFPB confiam nesse diagn?stico versus 12% do grupo evangelizador da vila dos pescadores. A outra diferen?a foi na resposta sobre a confian?a na lista ?nica de receptores: 36% dos estudantes do 7? per?odo de medicina da UFPB afirmaram confiar na lista versus 12% dos estudantes de direito do 3? ano da UFPB. A realiza??o desse estudo teve car?ter multidisciplinar com envolvimento de advogados e m?dicos

Organ transplantation is one of the greatest twentieth century advances in medicine, with success rates above 80%. Recent changes on donors profile, due to worldwide population aging, has led to modified organs acceptance criteria by the transplantation centers. This study aimed to describe the epidemiological, serological and clinical data of elderly organ donors, aged 60 years old or above, distributed by the National Transplant Center - NTC, Brazil, from 2011 to 2014, with special regard to organ donations progression and donation processes outcome related to the elderly organs donors. A descriptive, exploratory, retrospective, temporal and documentary series study was conducted with secondary data concerning Brazilian Federal Unit origin (UF), donation processes data and solid organs (heart, lung, liver and kidney) distribution, conducted by NTC, from 2011 to 2014, of older donors with 60 years or above. A total of 1,173 donation processes were analyzed, 38.6% of elderly donors were 60-64 years range and 31.5% were 65-69 years range. 57.9% were men and stroke (haemorrhagic) was the leading cause of death. Santa Catarina (20.2%), Cear?? (13%) and Rio de Janeiro (11.3%) were the most tendered states for national elderly organs distribution. Kidney was the most offered organ, followed by liver, heart and lung, in that order. Potential donor hospital stay was identified as an average of 5 - 6 days. Considering the use of vasoactive drugs and antibiotics, there was not a significant difference between donors with transplanted organs and donors with discarded organs. As for serologic tests, the presence or absence of a positive serologic test did not influence the acceptance of organs; however creatinine, urea and total bilirubin levels influenced this acceptance. Our results suggests that further researches are needed to better understand the old organ donor profile, consequently stimulating the use of organs from these donors by the transplantation centers and state transplant centers.

Abstract:
Human epidemiological and experimental animal studies show that a poor intra-uterine environment induced by restricted maternal diet during pregnancy leads to persistent alterations in the metabolism and physiology of the offspring and an altered susceptibility to chronic disease in adult life such as cardiovascular disease and metabolic syndrome. This phenomenon has been termed fetal programming. In rats, maternal protein restriction (MPR) during pregnancy alters the expression of specific genes involved in lipid and carbohydrate homeostasis such as glucocorticoid receptor (GR) and peroxisomal proliferator-activated receptor–alpha (PPARα). Evidence is accumulating which indicates that persistent changes in the expression of GR and PPARα are mediated by changes in the epigenetic regulation of these genes within the offspring. Epigenetics refers to processes that stably alter gene activity without altering DNA sequence. DNA methylation and histone modification are the most significant epigenetic modifications. However the mechanism by which alterations in maternal diet can induce the altered epigenetic regulation of genes such as GR or PPARα is currently unknown. The aim therefore of this project was to investigate the role of the DNA methyltransferase1 (Dnmt1). Dnmt1 is essential for the maintenance of DNA methylation patterns in the induction of the altered epigenetic regulation of genes in response to maternal diet. We initially investigated the effect of MPR on Dnmt1 mRNA expression in heart, brain and spleen from control and protein restriction (PR) offspring on PN34. We found that MPR altered the expression of Dnmt1 and the de novo DNA methyltransferases Dnmt3a, and 3b in a tissue specific manner. The effect of MPR on the expression and methylation of GR and PPARα was also tissue specific. However, in most tissues examined there was not a simple inverse relationship between GR or PPARα expression and methylation or with levels of Dnmt1 expression. To assess how widespread the changes in gene expression induced by MPR are, microarray analysis was conducted in E8 embryos from control and PR fed dams and results were validated by RT-PCR. Results showed that only relatively small subsets of genes were affected by MPR or global dietary restriction (UN). Gene ontology analysis also revealed that similar pathways were altered under condition of both maternal PR and UN and interestingly one of the pathways altered by both maternal PR and UN was chromatin modification. In both PR and UN embryos on E8 a decrease in Dnmt1, Dnmt3a and 3b expression was observed as well as a decrease in the histone methyltransferases EZH2, Suv39H1 and the HDAC Sirt1 in the embryos from PR dams compared to controls. Alterations in the expression of the DNA and histone methyltransferases in response to MPR were accompanied by changes in DNA methylation and histone modification at the GR promoter as early as E14.

Resumo de Limita??o no Suporte de vida Objetivo: Avaliar a incid?ncia de limita??o de suporte de vida (LSV) e as condutas m?dicas nas ?ltimas 48 horas de vida de crian?as internados em 7 UTIP de 3 regi?es brasileiras. Desenho: Estudo transversal, multic?ntrico e retrospectivo por revis?o de prontu?rio. Local (setting): 7 UTIP de hospitais universit?rios e terci?rios localizados em 3 regi?es Brasileiras, em Porto Alegre (2), S?o Paulo (2) e Salvador(3) Pacientes: todos pacientes que faleceram nas 7 UTIP no per?odo entre Janeiro de 2003 e dezembro de 2004. M?todos e principais resultados: Dois residentes de cada servi?o preencheram um protocolo padr?o com dados demogr?ficos, classificando o ?bito (reanima??o completa, ordem de n?o reanimar ou retirada de tratamento) e as condutas tomadas nas ?ltimas 48 horas de vida. Os dados foram comparados utilizando teste t de Student, Anova, Qui quadrado e RR. Dos 561 ?bitos, foram exclu?dos 36 com menos de 24 horas de interna??o, 61 com morte encef?lica e 36 prontu?rios n?o localizados. Em 56,5% dos ?bitos foram oferecidas manobras de ressuscita??o cardiopulmonar, com diferen?a entre regi?o sudeste e nordeste (p<0,001). A maior faixa et?ria (p=0,025) e maior tempo de interna??o na UTIP (p=0,001) foram fatores associados a n?o reanima??o. Em apenas 52,7% dos pacientes com LSV houve descri??o de plano no prontu?rio. O ?bito sem suporte respirat?rio ocorreu em apenas 14 pacientes. Em 66,1% pacientes com ordem de n?o reanimar as drogas inotr?picas foram mantidas ou aumentadas. Conclus?o: A incid?ncia de LSV tem aumentado nas UTIP brasileiras, havendo diferen?as entre regi?es. A ordem de n?o reanima??o ainda ? a pratica mais em nosso meio, havendo t?midas iniciativas de retirada de suporte. Resumo de Morte encef?lica Objetivo: Avaliar a incid?ncia de Morte Encef?lica (ME) bem como as condutas e protocolos adotados ap?s esta confirma??o diagn?stica em 7 UTIP localizadas em 3 regi?es Brasileiras. M?todo: Estudo transversal e multic?ntrico baseado na revis?o e an?lise retrospectiva de prontu?rios de todos os ?bitos ocorridos entre janeiro de 2003 e dezembro de 2004 em 7 UTIP localizadas em Porto Alegre (2), S?o Paulo (2) e Salvador (3). Dois residentes de cada servi?o previamente treinados preencheram protocolo padronizado avaliando dados demogr?ficos, a causa do ?bito, crit?rios para diagnostico de ME e a conduta m?dica adotada. Resultados: Identificamos 525 ?bitos, sendo 61 (11,6%) com diagn?stico de ME. A incid?ncia de ME diferiu entre as 7 UTIP (24,2% a 4,5%; p=0,015), por?m, sem diferen?a nas 3 regi?es (12% x 15% x 7%; p=0,052). A causa mais freq?ente foi Hemorragia Intracraniana (31,1%). Em 80% dos casos o diagnostico clinico de ME foi confirmado por exame complementar (100% na regi?o sul, 68% na sudeste e 72% na nordeste, p=0,02). A retirada de suporte vital ap?s diagnostico de ME diferiu nas 3 regi?es, sendo mais r?pida (p=0,04) no sul (1,8 ?1,9 hs) que no Sudeste (28,6 ?43,2hs) e Nordeste (15,5 ?17,1hs). Apenas 6 (9,8%) crian?as com ME foram doadoras de ?rg?os. Conclus?o: Apesar da lei que define crit?rios para Morte Encef?lica existir no Brasil desde 1997, verificamos que ela n?o ? obedecida uniformemente. Consequentemente, suporte vital desnecess?rio ? ofertado a indiv?duos j? mortos, existindo ainda um modesto envolvimento das UTIP com doa??es de ?rg?os

Abstract:
All eukaryotic cells possess mitochondrial DNA (mtDNA), which is maternally inherited through the oocyte, its replication being regulated by nuclear-encoded replication factors. It was hypothesised that mtDNA replication is highly regulated in oocytes, pre-implantation embryos and embryonic stem cells (ESCs) and that this may be disrupted following nuclear transfer (NT). MtDNA copy number decreased between 2-cell and 8-cell staged porcine embryos and increased between the morula and expanded blastocyst stages, coinciding with increased expression of mtDNA replication factors. Competent porcine oocytes replicated their mtDNA prior to and during in vitro maturation to produce and maintain the 100000 mtDNA copies required for fertilisation. Those oocytes in which mtDNA replication was delayed had reduced developmental ability. Expression of pluripotency-associated genes decreased as murine ESCs differentiated into embryoid bodies, although expression of mtDNA replication factors did not increase until the stage equivalent to organogenesis. Cross-species NT embryos in which the donor cell-derived mtDNA was replicated produced decreased developmental outcomes compared to those in which no mtDNA replication took place. Disruption of the strict regulation of mtDNA replication that occurs during early embryogenesis, as is likely following NT, may therefore contribute to the reduced developmental ability of embryos produced using such techniques.

Abstract:
Array signal processing is an important branch in the field of signal processing. In recent years, it has developed dramatically. It can be applied in such fields as radio detection and ranging, communication, sonar, earthquake, exploration, astronomy and biomedicine. The field of direction of array signal processing can be classified into self-adaption array signal processing and spatial spectrum, in which spatial spectrum estimation theory and technology is still in the ascendant status, and become a main aspect in the course of array signal processing. Spatial spectrum estimation is focused on investigating the system of spatial multiple sensor arrays, with the main purpose of estimating the signal’s spatial parameters and the location of the signal source. The spatial spectrum expresses signal distribution in the space from all directions to the receiver. Hence, if one can get the signal’s spatial spectrum, then the direction of arrival (DOA) can be obtained. As thus, spatial spectrum estimation is also called DOA estimation. DOA technology research is important in array signal processing, which is an interdisciplinary technology that develops rapidly in recent years, especially the direction of arrival with multiple signal sources, the estimation of coherent signal sources, and the DOA estimation of broadband signals. DOA estimation has a wide application prospect in radar, sonar, communication, seismology measurement and biomedicine. Over the past few years, all kinds of algorithms which can be used in DOA estimation have made great achievements, the most classic algorithm among which is Multiple Signal Classification (MUSIC). In this thesis I will give an overview of the DOA estimation based on MUSIC algorithm.

Abstract:
No contexto de Renormalização Wilsoniana, os fluxos do grupo de renormalização (RG flows) são um conjunto de equações diferenciais que define como as constantes de acoplamento de uma teoria dependem de uma escala de energia. o conteúdo destes é semelhante a como sistemas termodinâmicos estão relacionados com a temperatura. Neste sentindo, é natural olhar para estruturas nos fluxos que demonstram um comportamento termodinâmico. A teoria matemática para estudar estas equações é chamada de sistemas dinâmicos e aplicações desta têm sido usadas no estudo de RG flows. Como exemplo o teorema-C de Zamolodchikov e os equivalentes teoremas em dimensões maiores mostram que existe uma função monotonicamente decrescente ao longo do fluxo e é uma propriedade que se assemelha à segunda lei da termodinâmica, estão relacionadas com a função de Lyapunov no contexto de sistemas dinâmicos e podem ser usadas para excluir a possibilidade de comportamentos assintóticos exóticos, como fluxos periódicos ou ciclos limites. Estudamos a teoria de bifurcação e a teoria de índice, que foram propostas como sendo úteis no estudo de RG flows: a primeira pode ser usada para explicar constantes cruzando pela marginalidade e a segunda para extrair informação global do espaço em que os fluxos vivem. Nesta dissertação, também olhamos para aplicações em RG flows holográficos e tentamos buscar relações entre as estruturas em teorias holográficas e as suas duais teorias de campos.
In the context of Wilsonian Renormalization, renormalization group (RG) flows are a set of differential equations that defines how the coupling constants of a theory depend on an energy scale. These equations closely resemble thermodynamical equations and how thermodynamical systems are related to temperature. In this sense, it is natural to look for structures in the flows that show a thermodynamics-like behaviour. The mathematical theory to study these equations is called Dynamical Systems, and applications of that have been used to study RG flows. For example, the classical Zamolodchikov\'s C-Theorem and its higher-dimensional counterparts, that show that there is a monotonically decreasing function along the flow and it is a property that resembles the second-law of thermodynamics, is related to the Lyapunov function in the context of Dynamical Systems. It can be used to rule out exotic asymptotic behaviours like periodic flows (also known as limit cycles). We also study bifurcation theory and index theories, which have been proposed to be useful in the study of RG flows, the former can be used to explain couplings crossing through marginality and the latter to extract global information about the space the flows lives in. In this dissertation, we also look for applications in holographic RG flows and we try to see if the structural behaviours in holographic theories are the same as the ones in the dual field theory side.

Abstract:
The major threat that nuclear power plants (NPPs) pose to the safety of the public comes from the large amount radioactive material released during design-basis accidents (DBAs). Additionally, many aspects of Control Room Habitability, Environmental Reports, Facility Siting and Operation derive from the design analyses that incorporated the earlier accident source term and radiological consequence of NPPs. Depending on current applications, majority of Chinese NPPs adopt the method of TID-14844, which uses the whole body and thyroid dose criteria. However, alternative Source Term (AST) are commonly used in AP1000 and some LWRs (such as Beaver Valley Power Station, Units No. 1 and No. 2, Calvert Cliffs Nuclear Power Plant, Unit Nos. 1 And 2, Kewaunee Power Station and so on), so it is attempted to adopt AST in radiological consequence analysis of other nuclear power plants. By introducing and implementing the method of AST defined in RG 1.183 and using integral safety analysis code, a pressurized water reactor (PWR) of 900 MW nuclear power plant analysis model is constructed and the radiological consequence induced by Main Steam Line Break (MSLB) accident is evaluated. For DBA MSLB, the fractions of core inventory are assumed to be in the gap for various radionuclides and then the release from the fuel gap is assumed to occur instantaneously with the onset of assumed damage. According to the assumptions for evaluating the radiological consequences of PWR MSLB, dose calculation methodology is performed with total effective dose equivalent (TEDE) which is the criteria of dose evaluation. Compared with dose criteria of RG 1.183, the dose of control room, exclusion area boundary and outer boundary of low population zone are acceptable.
