Protocolos de indução e sincronização do estro em ovelhas

O objetivo do presente trabalho foi testar a indução e sincronização do estro em ovelhas utilizando-se diferentes períodos de permanência do progestágeno, dose única de PGF2α ou efeito macho. Para tanto dois experimentos foram realizados: no experimento 1, as ovelhas (n=48) receberam esponjas vaginais impregnadas com MAP (medroxiprogesterona) e foram divididas em 2 grupos: G-9 e G-14, ou seja, MAP por nove ou 14 dias com aplicação de PGF2α na retirada do progestágeno e detecção de estro com reprodutores. Não houve diferenças (p<0,05) na manifestação no estro (69,6 % e 80%), na porcentagem de prenhez (34,8% e 44%) ou de concepção (50% e 55%) nos grupos G-9 e G-14, respectivamente. No experimento 2, as ovelhas (n=151) foram aleatoriamente divididas em 3 grupos: G-6, cada ovelha recebeu MAP por seis dias e aplicação de PGF2α na retirada do progestágeno; G-PGF, cada ovelha recebeu dose única de PGF2α e G-EM para avaliar o efeito macho foram introduzidos machos entre ovelhas previamente separadas dos mesmos. A porcentagem de manifestação de estro foi maior (p<0,05) nos grupos G-6 (58%) e G-PGF (39%) quando comparados ao G-EM (11%). Concluímos ser possível diminuir o tempo de permanência do progestágeno, porém o uso de luteolítico, em período de transição da estacionalidade reprodutiva, sem o progestágeno, resulta em baixa manifestação de estro.

Adoção de práticas da produção enxuta na construção civil

The civil construction sector has been stimulated to industrialize itself by the adoption of lean production practices in its constructive process. Given this fact, this research verify and identify good practices and difficulties in implementing lean production in construction companies in the State of São Paulo, in order to be able to formulate recommendations to potentiate the performance of the lean concepts applied. The research method used was a multiple case study, where the companies analyzed are constructors that have already initiated the lean application in their systems. From the results, a case analysis was conducted in order to note the constructors' situation in relation to lean construction and, base on this analysis, recommendations were proposed for the companies reflect on lean principles and apply them along to your construction management

Indicadores-chave de desempenho e a gestão integrada da mineração

The exceptional advance of information technology and computer application to the mineral sector has allowed the automation of several processes of the mineral value chain. ERP systems (Enterprise Resource Planning) provided the platform for the efficient integration of all support activities of the mineral value chain. Despite all advances gathered with the application of computers, it was not possible to date, to effectively integrate the primary activities of the mineral value chain. The main reason for that are the uncertainties present in the productive process, which are intrinsic to the business, and the difficulty to quantify and qualify the benefits obtained with this integration due to the lack of a clear definition of the key performance indicators (KPIs). This work presents an analysis of the ERP systems application in Brazilian mining, identifies the KPIs of some of the most important Brazilian mining companies, and discusses the importance of mapping and measuring these indicators for the effective. management of the mining business.

Expression of cancer-testis antigens MAGE-A4 and MAGE-C1 in oral squamous cell carcinoma

Background Tumor markers are genes or their products expressed exclusively or preferentially in tumor cells and cancer-testis antigens (CTAs) form a group of genes with a typical expression pattern expressed in a variety of malignant neoplasms. CTAs are considered potential targets for cancer vaccines. It is possible that the CTA MAGE-A4 (melanoma antigen) and MAGE-C1 are expressed in carcinoma of the oral cavity and are related with survival. Methods This study involved immunohistochemical analysis of 23 patients with oral squamous cell carcinoma (SCC) and was carried out using antibodies for MAGE-A4 and MAGE-C1. Fisher's exact test and log-rank test were used to evaluate the results. Results The expression of the MAGE-A4 and MAGE-C1 were 56.5% and 47.8% without statistical difference in studied variables and survival. Conclusion The expression of at least 1 CTA was present in 78.3% of the patients, however, without correlation with clinicopathologic variables and survival. (c) 2011 Wiley Periodicals, Inc.

ROLE OF FOCAL ADHESION KINASE IN LUNG REMODELING OF ENDOTOXEMIC RATS

Despite significant advances in the care of critically ill patients, acute lung injury continues to be a complex problem with high mortality. The present study was designed to characterize early lipopolysaccharide (LPS)-induced pulmonary injury and small interfering RNA targeting focal adhesion kinase (FAK) as a possible therapeutic tool in the septic lung remodeling process. Male Wistar rats were assigned into endotoxemic group and control group. Total collagen deposition was performed 8, 16, and 24 h after LPS injection. Focal adhesion kinase expression, interstitial and vascular collagen deposition, and pulmonary mechanics were analyzed at 24 h. Intravenous injection of small interfering RNA targeting FAK was used to silence expression of the kinase in pulmonary tissue. Focal adhesion kinase, total collagen deposition, and pulmonary mechanics showed increased in LPS group. Types I, III, and V collagen showed increase in pulmonary parenchyma, but only type V increased in vessels 24 h after LPS injection. Focal adhesion kinase silencing prevented lung remodeling in pulmonary parenchyma at 24 h. In conclusion, LPS induced a precocious and important lung remodeling. There was fibrotic response in the lung characterized by increased amount in total and specific-type collagen. These data may explain the frequent clinical presentation during sepsis of reduced lung compliance, oxygen diffusion, and pulmonary hypertension. The fact that FAK silencing was protective against lung collagen deposition underscores the therapeutic potential of FAK targeting by small interfering RNA.

Aerobic exercise attenuates pulmonary injury induced by exposure to cigarette smoke

It has recently been suggested that regular exercise reduces lung function decline and risk of chronic obstructive pulmonary disease (COPD) among active smokers; however, the mechanisms involved in this effect remain poorly understood. The present study evaluated the effects of regular exercise training in an experimental mouse model of chronic cigarette smoke exposure. Male C57BL/6 mice were divided into four groups (control, exercise, smoke and smoke+exercise). For 24 weeks, we measured respiratory mechanics, mean linear intercept, inflammatory cells and reactive oxygen species (ROS) in bronchoalveolar lavage (BAL) fluid, collagen deposition in alveolar walls, and the expression of antioxidant enzymes, matrix metalloproteinase 9, tissue inhibitor of metalloproteinase (TIMP) 1, interleukin (IL)-10 and 8-isoprostane in alveolar walls. Exercise attenuated the decrease in pulmonary elastance (p<0.01) and the increase in mean linear intercept (p=0.003) induced by cigarette smoke exposure. Exercise substantially inhibited the increase in ROS in BAL fluid and 8-isoprostane expression in lung tissue induced by cigarette smoke. In addition, exercise significantly inhibited the decreases in IL-10, TIMP1 and CuZn superoxide dismutase induced by exposure to cigarette smoke. Exercise also increased the number of cells expressing glutathione peroxidase. Our results suggest that regular aerobic physical training of moderate intensity attenuates the development of pulmonary disease induced by cigarette smoke exposure.

Jean Bodin, o Methodus e a Clio tucidideana: as figurações heroicizantes do historiador

Apreciando as representações figuradas na ideia de uma Clio Tucidideana por fins do século XVI, propõe-se refletir sobre a associação entre a concepção antiga de herói e a moderna de gênio como parâmetro epistemológico que catalisa a apreciação da excelência da práxis historiográfica. Aborda-se essa reflexão tomando em particular as proposições elaboradas sobre a escrita da História no Metodus de Jean Bodin que juntamente com La Popelinière e Thomas Hobbes configuram historiograficamente a ideia da Clio Tucidideana conceituada por Cesare Ripa.
