Abstract
BACKGROUND Metastatic castration-sensitive prostate cancer (mCSPC) is commonly classified into high- and low-volume subgroups which have demonstrated differential biology, prognosis, and response to therapy. Timing of metastasis has similarly demonstrated differences in clinical outcomes; however, less is known about any underlying biologic differences between these disease states. Herein, we aim to compare transcriptomic differences between synchronous and metachronous mCSPC and identify any differential responses to therapy. PATIENTS AND METHODS We performed an international multi-institutional retrospective review of men with mCSPC who completed RNA expression profiling evaluation of their primary tumor. Patients were stratified according to disease timing (synchronous versus metachronous). The primary endpoint was to identify differences in transcriptomic profiles between disease timing. The median transcriptomic scores between groups were compared with the Mann-Whitney U test. Secondary analyses included determining clinical and transcriptomic variables associated with overall survival (OS) from the time of metastasis. Survival analysis was carried out with the Kaplan-Meier method and multivariable Cox regression. RESULTS A total of 252 patients were included with a median follow-up of 39.6 months. Patients with synchronous disease experienced worse 5-year OS (39% versus 79%; P < 0.01) and demonstrated lower median androgen receptor (AR) activity (11.78 versus 12.64; P < 0.01) and hallmark androgen response (HAR; 3.15 versus 3.32; P < 0.01). Multivariable Cox regression identified only high-volume disease [hazard ratio (HR) = 4.97, 95% confidence interval (CI) 2.71-9.10; P < 0.01] and HAR score (HR = 0.51, 95% CI 0.28-0.88; P = 0.02) significantly associated with OS. Finally, patients with synchronous (HR = 0.47, 95% CI 0.30-0.72; P < 0.01) but not metachronous (HR = 1.37, 95% CI 0.50-3.92; P = 0.56) disease were found to have better OS with AR and non-AR combination therapy as compared with monotherapy (P value for interaction = 0.05). CONCLUSIONS We have demonstrated a potential biologic difference between metastatic timing of mCSPC. Specifically, for patients with low-volume disease, those with metachronous low-volume disease have a more hormone-dependent transcriptional profile and exhibit a better prognosis than synchronous low-volume disease.

Abstract
Um experimento foi realizado com duração de 27 semanas, com poedeiras da linhagem Shaver Brown em produção, seu objetivo foi avaliar a mobilização de cálcio e fósforo ósseos para a formação da casca dos ovos, assim como, acompanhar as variações na qualidade óssea ao longo do ciclo de produção. Foram utilizadas 64 aves. O delineamento experimental foi o inteiramente casualizado com dois tratamentos (porcentagem de cálcio na dieta) e quatro repetições de oito aves cada. As dietas utilizadas foram isoprotéicas e isocalóricas, com níveis adequados (3,8%) e baixos (1,8%) de cálcio. Realizaram-se análises densidade mineral óssea (DMO) das tíbias e fêmures às 16, 22, 28, 34 e 40 semanas de idade. Após cada coleta radiográfica 4 aves por tratamento, foi abatida para realização de análise de resistência óssea (RO), índice Seedor (IS), teor de matéria seca (MS), teor de minerais totais (MIN) e os teores de cálcio e fósforo (Ca e P). Os valores de produção de ovos, produção de massa de ovos e qualidade da casca também foram avaliados. Foi possível concluir que as aves mobilizaram minerais ósseos para a produção de ovos, independentemente do tratamento e que as aves que receberam dietas com níveis baixos de cálcio tiveram a qualidade das cascas dos ovos prejudicadas.

Abstract
O objetivo de estudo foi o de avaliar o efeito do jejum de ração e água antes do abate sobre o rendimento de carcaça e cortes, perda de peso vivo, conteúdo do papo, intestino e moela, matéria seca das fezes, bem como volume globular médio e proteína total plasmática do soro. Foram utilizados 600 pintos machos da linhagem Ross, criados até 42 dias de idade, quando foram submetidos a três períodos de jejum (zero, quatro ou oito horas). A duração do período de jejum afetou (p<0,05) a perda de peso vivo, o rendimento de carcaça, carne de pernas, pés, conteúdo do papo e intestino. Aumentando-se o período de jejum até 4 horas, aumentou-se a perda de peso vivo e o rendimento de carcaça e patas, mas diminuiu-se o rendimento de pernas e o conteúdo do papo e do intestino. Não houve efeito (p>0,05) do período de jejum sobre as demais variáveis estudadas.

Abstract
O experimento foi realizado com o objetivo de avaliar o desempenho de codornas poedeiras alimentadas por diferentes períodos com milho moído ou ração de postura durante sete dias após três dias de jejum, método de muda utilizado. Após esse período, as aves foram alimentadas com ração de postura durante as 20 semanas do período experimental. Utilizou-se um delineamento inteiramente ao acaso com três tratamentos (ração de postura por sete dias, ração de postura por três dias e milho moído por quatro dias e milho moído por sete dias), e quatro repetições de 24 aves por parcela. Os resultados mostraram que aves alimentadas apenas com ração de postura nos sete primeiros dias após o jejum apresentaram maior produção de ovos nas seis primeiras semanas do período de produção pós-muda. Porém, não foi constatado efeito de tratamento sobre a produção de ovos, peso dos ovos, consumo de ração e conversão alimentar durante as 20 semanas do período experimental.

Abstract
O experimento foi conduzido nas instalações da Faculdade de Medicina Veterinária e Zootecnia, UNESP, Campus de Botucatu, utilizando-se dois mil pintos de um dia de idade, da linhagem Ross, distribuídos em um delineamento inteiramente casualisado em esquema fatorial 2 x 2 (sexos x níveis de lisina) e criados até 49 dias de idade. As aves foram alimentadas com dietas: inicial (0-21 dias), crescimento (22-42 dias) e acabamento (43-49 dias), contendo 100% dos níveis de lisina recomendados pelo NRC (1994), ou 110% nas rações inicial e de crescimento e 120% na ração de acabamento. Os frangos foram abatidos aos 28, 35, 42 e 49 dias de idade quando os rendimentos de carcaça e de peito foram determinados. Os níveis de lisina não afetaram (p>0,05) o ganho de peso, conversão alimentar e o rendimento de carcaça, mas os níveis altos resultaram em menores porcentagens de gordura abdominal quando comparados aos níveis baixos de lisina, nas fêmeas. A inclusão de lisina na dieta não melhorou o rendimento de carcaça e de peito aos 28, 35, 42 e 49 dias de idade (p>0,05). Portanto, pode-se concluir que o aumento dos níveis de lisina acima do recomendado pelo NRC (1994) não apresentou influência sobre as características avaliadas.

Abstract
O experimento teve como objetivo estudar os efeitos de níveis de cantaxantina sobre o desempenho e a coloração das gemas dos ovos de galinhas poedeiras. Foram utilizadas 384 galinhas da linhagem Hisex Brown, em um delineamento em blocos ao acaso, contendo seis tratamentos (0, 12, 24, 36, 48 e 60 ppm de cantaxantina), com oito repetições de oito aves por parcela. O período experimental foi de 56 dias. A coleta de ovos foi realizada diariamente e a análise de coloração dos ovos foi efetuada com o abanico colorimétrico da Roche. Durante os 14 dias do período inicial do experimento, a melhor coloração das gemas foi obtida com a adição de 60 ppm de cantaxantina, atingindo-se a cor plateau de 14,3 do leque colorimétrico Roche aos 5,43 dias de inclusão do pigmentante. Considerando-se o período experimental total, os níveis de cantaxantina utilizados melhoraram de forma quadrática a coloração das gemas, sem influenciar os parâmetros produtivos e demais características de qualidade dos ovos de poedeiras comerciais.

Abstract
Um experimento foi conduzido para avaliar os efeitos da suplementação de metionina em dietas de crescimento (22 a 42 dias de idade) sobre o desempenho, rendimento e composição química da carcaça de frangos de corte. Foram utilizados 2000 frangos de corte da linhagem comercial Ross, sexados, distribuídos em um delineamento ao acaso, em esquema fatorial 2 x 5 (sexo e níveis de metionina) com quatro repetições de 50 aves cada. As dietas foram formuladas para conter 100% ,110%, 120%, 130% e 140% dos níveis de metionina recomendados pelo NRC (1994). Aos 42 dias de idade, as aves foram abatidas para avaliar a quantidade de gordura abdominal, bem como o rendimento e a composição química da carcaça. Ao aumentar o nível de metionina da dieta, não houve efeito (p> 0,05) sobre o ganho de peso, consumo de ração, conversão alimentar, mortalidade, gordura abdominal, e rendimento de carcaça, bem como, umidade, proteína, gordura e cinzas do peito e pernas. Não foi verificado efeito (p>0,05) de interação entre nível de metionina e sexo, mas as fêmeas apresentaram maior percentual de gordura abdominal (p<0,05) que os machos. Como o nível de metionina não afetou o desempenho, rendimento e composição química da carcaça, concluiu-se que a recomendação sugerida pelo NRC (1994) de 0,38% para frangos de corte no período de 22 a 42 dias de idade está adequada.

Abstract
O experimento foi conduzido nas instalações experimentais da Faculdade de Medicina Veterinária e Zootecnia - UNESP, Campus de Botucatu, SP, Brasil, com o objetivo de avaliar o efeito da densidade de criação e do sexo sobre o empenamento, incidência de lesões na carcaça e a qualidade de carne de peito de frangos de corte. Foram utilizados 1950 pintos de corte sexados, da linhagem Ross, distribuídos em um delineamento inteiramente casualizado, com esquema fatorial com 3 densidades (10, 13 e 16 aves/m²) e dois sexos com 5 repetições, sendo que uma foi destinada exclusivamente para reserva, criados até os 42 dias de idade. Aos 28, 35 e 42 dias foram amostradas 3 aves por repetição para a determinação do empenamento através da porcentagem de penas e 10 aves para a determinação do escore de empenamento. Também aos 42 dias de idade todas as aves foram identificadas na pata com anilhas numeradas e submetidas à avaliação da incidência de lesões na pele. Foram escolhidas ao acaso 5 aves por repetição para a determinação da qualidade da carne de peito. Pode-se concluir que o aumento na densidade de criação promoveu uma diminuição na velocidade de empenamento e, conseqüentemente, uma maior incidência de lesões na carcaça. O comprimento, a largura e a espessura do peito foram menores para as aves criadas na maior densidade, e a perda de peso por cozimento foi maior para as aves criadas na maior densidade.

Abstract
As condições ideais dos frangos de corte no momento do abate devem ser conhecidas a fim de possibilitar a produção de carne de excelente qualidade, uma vez que diversos fatores pré e pós-abate estão envolvidos na qualidade final. Em condições normais de abate e processamento, a retirada de ração é feita de 6 a 8 horas antes da apanha das aves, resultando em um período total de jejum de 8 a 12 horas antes do abate, para esvaziar o intestino e com isso minimizar a contaminação no abatedouro. A escalda, depena e evisceração são pontos importantes de contaminação cruzada no abatedouro devido à grande quantidade de microorganismos aderidos às penas, pele e patas das aves e ao rompimento das vísceras durante a evisceração. Entretanto, a desidratação da carcaça começa imediatamente após o início do jejum. Períodos prolongados de jejum podem afetar o pH das diversas partes do intestino, aumentando a presença de Salmonella e outros microorganismos patogênicos. Além disso, determinam uma maior contaminação pela bile, e são, subjetivamente, associados à fragilidade dos intestinos durante a evisceração mecânica. Portanto, os esquemas de processamento devem ser estabelecidos levando-se em conta a integridade e o esvaziamento do intestino e da vesícula biliar, bem como a desidratação e os seus efeitos sobre o bem estar das aves, contaminação da carcaça e qualidade da carne. Como alguns efeitos do jejum ainda não são bem conhecidos, sugerem-se pesquisas nas seguintes áreas: definir o tempo ótimo de jejum para atender o bem estar das aves, minimizar a contaminação e otimizar os parâmetros de qualidade de carcaça; estudar os efeitos de períodos prolongados de jejum sobre o pH e a colonização do papo, pró-ventrículo, moela, intestino delgado, intestino grosso e cecos por enterobactérias, como Salmonella, por exemplo; efeito do jejum sobre o tamanho e cor do fígado. O resultado esperado é um aumento na qualidade final dos produtos aliado a uma redução nas perdas e no custo de produção.

Abstract
BACKGROUND Previously we reported that cultures of fine-needle aspiration biopsy (FNAB) samples synthesize different cytokine pattern depending on the alloimmune response towards the kidney graft. However, we failed to find a clear picture for growth factors implicated in early T-cell activation (interferon-gamma, interleukin [IL]-4, IL-12), although we observed that interleukin-1 receptor antagonist (IL-1ra) was associated with absence of acute rejection. We have now studied tumor necrosis factor-alpha (TNF-alpha) and its two soluble receptors, sTNFRI and sTNFRII, IL-1beta and soluble IL-1 receptor II (sIL-1RII), and leukemia inhibitory factor (LIF), all potential modulators of T-cell activation. METHODS Sixty-six cadaver kidney transplants (KTX) were divided into four groups: group 1, day 7 after KTX, stable (n=30); group 2, day 7 after KTX, 8+/-4.5 days before acute rejection (n=12); group 3, first day of acute rejection (n=17); and group 4, day 14 after KTX, stable (n=32). Patients from groups 1 and 4 remained rejection-free for the first 6 months. All rejection episodes were confirmed by core renal biopsy. FNAB samples were cultured according to our published methodology, and culture supernatants were collected at 48 hr and analyzed by ELISA for IL-1beta, sIL-1RII, TNF-alpha, sTNFRI, sTNFRII, and LIF. Serum levels for sIL-1RII, sTNFRI, and sTNFRII were also measured. RESULTS FNAB cultures from groups 1 and 4 synthesized significantly lower amounts of sTNFRI and sTNFRII than those from either groups 2 or 3. Both sTNFRI and sTNFRII reached high positive and negative predictive values for acute rejection. IL-1beta and sIL-1RII were synthesized by all groups but without differences. No trace of LIF and TNF-alpha was found. sTNFRII was significantly higher in serum from group 3. CONCLUSIONS Both TNF receptors were positively associated with acute rejection and were good predictors of impending acute rejection. The ratio of sIL-1RII over IL-1 (together with IL-1ra that we previously measured in FNAB cultures) suggests that IL-1 actions may be inhibited with current immunosuppression early after transplantation.

Abstract
BACKGROUND The new cyclosporin (CsA) formulation, Neoral, has different pharmacokinetics compared with Sandimmune (SIM). Larger area under the curve (AUC) values with equivalent trough blood values are reached when Neoral is administered at equivalent doses to SIM. Previously, we showed a great diagnostic reliability when using cytofluorometric analysis from fine-needle aspiration biopsy (FNAB) samples. We investigated possible changes brought about by Neoral on lymphocyte subsets and the repercussions on the activation score cut-off for acute rejection, defined under SIM treatment. METHODS Of 63 patients that received SIM, 40 remained rejection-free and 23 suffered one episode of rejection. Of 52 patients that received Neoral, 38 remained rejection-free. Peripheral blood lymphocytes (PBL) and lymphocytes from FNAB taken on days 7 and 14 post-transplantation and on the first day of acute rejection were analysed by flow cytometry. RESULTS Trough blood CsA levels were not different between SIM and Neoral treatments. Among rejection-free patients, a significant down-regulation of CD3DR and of CD8DR expression on both graft-infiltrating lymphocytes (GIL) and PBL, and significant up-regulation of naïve T cells on GIL were observed with Neoral. These changes were followed by a significant down-regulation of the activation score with Neoral. Conversely, within the acute rejection group, the activation score was significantly higher with Neoral than with SIM. The activation score performed equally well in Neoral transplants compared with what we had reported with SIM. CONCLUSIONS Our study indicates that Neoral elicits stronger immunosuppressive effects in stable patients, which eventually should translate into better clinical efficiency. However, when acute rejection supervenes, the treatment breakthrough seems stronger with Neoral. Cytofluorometric studies from FNAB samples showed that diagnostic reliability was maintained at a high level under Neoral therapy.

Abstract
BACKGROUND Focal segmental glomerulosclerosis (FSGS) aetiology remains undefined although a derangement of lymphocytes and monocytes macrophages, at least, has been strongly suspected. We report the graft-infiltrating phenotypes and their cytokine production in a case of FSGS recurrence post-transplantation. METHODS The kidney transplant recipient suffered immediate FSGS recurrence. Aspiration biopsies were done at the first and second week post-surgery and were analysed by flow cytometry. The cytokine analysis was done on aspiration sample culture supernatants and serum by enzyme-linked immunosorbent assay. RESULTS High expression of CD3CD69, CD3CD71 and CD4CD29 was found on infiltrating lymphocytes. Biopsy cultures pointed to a Th0/Th1 pattern of cytokine production as well as significant synthesis of transforming growth factor-beta1. Interestingly, monocyte chemokines were absent. CONCLUSION We report evidence of intragraft lymphocyte activation in the early days of FSGS recurrence. Aspiration biopsy cultures showed failure of cyclosporin A to inhibit interleukin-2 (IL-2) production by infiltrating lymphocytes. If our findings are confirmed in similar patients, a trial with anti-IL-2-receptor antibody could be warranted.

Abstract
BACKGROUND Peripheral blood lymphocyte (PBL) analysis by flow cytometry has been inconsistently reported as an adjunctive method for diagnosing acute kidney transplant rejection. However, there is good evidence that lymphocytes infiltrating renal grafts differ from those found at the peripheral level. We hypothesized that the study of aspiration biopsy samples in conjunction with PBL by flow cytometry would enable us to diagnose acute rejection crisis reliably. METHODS Lymphocytes from PBL and aspiration biopsies of kidney transplant patients were analyzed. Fifty-one stable patients, rejection-free for the first 6 months, were studied on day 7 and day 30 after transplantation and were compared with 32 patients with 40 acute rejection episodes. RESULTS Significant differences were observed for several lymphocyte subpopulations on aspiration biopsy samples comparing stable patients with rejection patients. In contrast, PBL analysis was not helpful in differentiating the two groups of patients. By combining the expression of several activation markers inside the graft with CD3DR and CD3CD25 aspiration biopsy to peripheral blood ratios, we obtained very good values for sensitivity and specificity-83.9% and 90.5%, respectively. The positive predictive value for rejection among dysfunctional grafts reached 85.8%. CONCLUSIONS Flow cytometry study of aspiration biopsy samples of kidney transplant patients is a reliable and powerful method to diagnose acute rejection episodes, although it is needed to consider several lymphocyte phenotypes; cytofluorometric analysis of PBL is important because it provides graft-infiltrating cell to peripheral blood lymphocyte ratios. This safe and rapid test may significantly improve the management of kidney transplant patients.

Abstract
BACKGROUND Monocytes-macrophages are found within kidney allografts during the first days after surgery, where they perform "housekeeping" tasks, participate in postreperfusion injury, and act as antigen-presenting cells, as well as become involved in the effector phase of acute rejection. They also seem to play a prominent role in chronic rejection. We quantified their presence in fine-needle aspiration biopsies and studied the growth factors that, we hypothesized, would mark the different implications of the presence of monocytes-macrophages. METHODS Fine-needle aspiration biopsies were obtained from 56 adult renal transplants and analyzed for CD14+ using the alkaline phosphatase-anti-alkaline phosphatase procedure. Thirty-three patients were studied on the production of interleukin (IL)-1 receptor antagonist (IL-1ra), IL-6, IL-8, macrophage colony-stimulating factor, monocyte chemotactic protein 1, and macrophage inflammatory protein 1alpha by aspiration biopsies cultures using enzyme-linked immunosorbent assay techniques. RESULTS CD14+ cells were present at significantly higher numbers in steroid-resistant acute rejections but also during the first days after surgery, especially if acute tubular necrosis was present. We found a significantly higher production of IL-1ra by rejection-free patients compared with acutely rejecting patients, and this difference was already established on day 7 after surgery (10+/-10.5 days before rejection). CONCLUSIONS Monocytes-macrophages are present at higher numbers in aspiration biopsies of kidney transplant patients suffering either acute tubular necrosis or steroid-resistant rejections, but they are present during the first days after transplant in stable patients, too. The production of IL-1ra is significantly up-regulated in stable patients, which suggests that monocytes-macrophages may constitute an early key factor in the down-regulation of the anti-allograft immune response.

Abstract
Four trials of identical experimental design were conducted to determine the effects of temperature, dietary Lys level, and dietary Arg:Lys ratios on performance and carcass yield of male broilers. Birds of a commercial strain were grown from 21 to 42 d of age in wire-floored finishing batteries placed in environmental chambers. The chambers were programmed to provide either a constant thermoneutral temperature (21.1 C), a constant cold temperature (15.5 C), or a cycling hot diurnal temperature (25.5 to 33.3 C). Within each environment there was a factorial arrangement of three Lys levels (1.0, 1.1, and 1.2%) with four Arg:Lys ratios (1.1:1, 1.2:1, 1.3:1, and 1.4:1). Environmental temperature significantly influenced virtually every characteristic examined. Hot cyclic temperatures reduced weight gain, feed intake, and breast meat yield, and increased feed conversion, dressing percentage, leg quarter yield, and abdominal fat content. The cold environment promoted increased feed intake and mortality. Ascites and cardiomyopathy were the leading causes of death under cold exposure and thermoneutral conditions, whereas complications arising from heat exposure were the main cause of death under hot cyclic conditions. Levels of Lys affected leg quarter yield and abdominal fat content over all environments but increased breast meat yield only under cold conditions. Increasing Arg:Lys ratios improved feed conversion and dressing percentage and reduced abdominal fat content; it could not be determined whether these responses were consistent with Arg per se or were due to a nonspecific N response. As increasing Lys levels or Arg:Lys ratios did not improve weight gain, increase breast meat yield, or attenuate adverse effects due to heat or cold exposure, it is concluded that the levels of Lys and Arg suggested for 21 to 42 d by the NRC are adequate for birds of this age under the environmental conditions encountered.
