1Research advances on the multiple uses of Moringa oleifera: a sustainable alternative for socially neglected population显示文摘Moringa oleifera Lam(Moringaceae) is a plant with high nutritional and medicinal value. Native to India, it is now widely distributed throughout tropical and subtropical regions of the world. Its different parts are sources of proteins, vitamins and minerals and present different pharmacological and biotechnological potential. Moreover, M. oleifera seeds are widely used in water and effluent treatment, for their coagulation, flocculation and sedimentation properties, their ability of improving water quality, by reducing organic matter and microbial load, with special applicability in intensive animal production systems, such as aquaculture. In addition, due to its high nutritional value and several medicinal properties, this tree may act as a nutritional and medical alternative for socially neglected populations. In this context, this review gathers information on M. oleifera, emphasizing its chemical constituents, nutritional, pharmacological and antimicrobial properties, applications in the treatment of water effluents, and ecological and social aspects.Raimunda Samia Nogueira Brilhante Jamille Alencar Sales Vandbergue Santos Pereira Débora de Souza Collares Maia Castelo-Branco Rossana de Aguiar Cordeiro Célia Maria de Souza Sampaio Manoel de Araújo Neto Paiva Joao Bosco Feitosa dos Santos JoséJúlio CostaSidrim Marcos Fábio Gadelha Rocha 2017Asian Pacific Journal of Tropical Medicine2017,10,7:10

3Percutaneous radiofrequency ablation for early hepatocellular carcinoma: Risk factors for survival显示文摘AIM: To evaluate outcomes of radiofrequency ablation(RFA) therapy for early hepatocellular carcinoma(HCC) and identify survival- and recurrence-related factors. METHODS: Consecutive patients diagnosed with early HCC by computed tomography(CT) or magnetic resonance imaging(MRI)(single nodule of ≤ 5 cm, or multi-(up to 3) nodules of ≤ 3 cm each) and who underwent RFA treatment with curative intent between January 2010 and August 2011 at the Instituto do Cancer do Estado de S o Paulo, Brazil were enrolled in the study. RFA of the liver tumors(with 1.0 cm ablative margin) was carried out under CT-fluoro scan and ultrasonic image guidance of the percutaneous ablation probes. Procedure-related complications were recorded. At 1-mo post-RFA and 3-mo intervals thereafter, CT and MRI were performed to assess outcomes of complete response(absence of enhancing tissue at the tumor site) or incomplete response(enhancing tissue remaining at the tumor site). Overall survival and diseasefree survival rates were estimated by the Kaplan-Meier method and compared by the log rank test or simple Cox regression. The effect of risk factors on survival was assessed by the Cox proportional hazard model. RESULTS: A total of 38 RFA sessions were performed during the study period on 34 patients(age in years: mean, 63 and range, 49-84). The mean follow-up time was 22 mo(range, 1-33). The study population showed predominance of male sex(76%), less severe liver disease(Child-Pugh A, n = 26; Child-Pugh B, n = 8), and single tumor(65%). The maximum tumor diameters ranged from 10 to 50 mm(median, 26 mm). The initial(immediately post-procedure) rate of RFAinduced complete tumor necrosis was 90%. The probability of achieving complete response was significantly greater in patients with a single nodule(vs patients with multi-nodules, P = 0.04). Two patients experienced major complications, including acute pulmonary edema(resolved with intervention) and intestinal perforation(led to death). The 1- and 2-year overall survival rates were 82% and 71%, respectively. Sex, tumor size, initial response, and recurrence status influenced survival, but did not reach the threshold of statistical significance. Child-Pugh class and the model for end-stage liver disease score were identified as predictors of survival by simple Cox regression, but only Child-Pugh class showed a statistically significant association to survival in multiple Cox regression analysis(HR = 15; 95%CI: 3-76 mo; P = 0.001). The 1-and 2-year cumulative disease-free survival rates were 65% and 36%, respectively. CONCLUSION: RFA is an effective therapy for local tumor control of early HCC, and patients with preserved liver function are the best candidates.Luciana Kikuchi Marcos Menezes Aline L Chagas Claudia M Tani Regiane SSM Alencar Marcio A Diniz Venncio AF Alves Luiz Augusto Carneiro D’Albuquerque Flair José Carrilho 2014World Journal of Gastroenterology2014,20,6:5
4Detection of flock movement and behaviour of broiler chickens at different feeders using image analysis显示文摘The behaviour of broiler chickens has been extensively studied as a function of stocking density and environmental conditions,but limited information was reported in the scientific literature about the effect of feeder type on birds’feeding process.The main objective of this study was to assess the effects of three different feeder types in relation to the birds’behaviour in its surroundings.The analysed feeders were:tube-type with partition grid(F1);tube-type without partition grid(F2);and automatic type with partition grid(F3).The considered variables were:occupied area(OA);activity index(AI)(flock movement);total birds presented in the area(TB);and birds effectively eating(EE).OA and AI were calculated by computational image analysis while TB and EE were manually measured.The results indicated that the feeder type could have influenced the birds’behaviour regarding to OA(R2=0.56),TB(R2=0.48),and EE(R2=0.40),but AI(R2=0.01)was not found to be directly influenced by the feeder type.A higher percentage of birds effectively eating were found in F2(86.4%),which was the one with the largest free area to access the feed.Similar average number of total birds was found in F1,but with a lower percentage of individuals effectively eating(63.3%),which means that birds were nearby this feeder performing other behaviours.Since the assessed feeders were in the same house under the same conditions,it can be suggested that not only the free area to access the feed but potentially the design of feeders could have influenced the birds’feeding preference.The real beneficial effect of the adoption of partition grid on feed trays is still uncertain,and it is also unclear whether the financial value of reduced wastage would compensate the possible reduction in feed intake.Diego Pereira Neves Saman Abdanan Mehdizadeh Matthew Tscharke Irenilza de Alencar Nääs Thomas Michael Banhazi 2015Information Processing in Agriculture2015,2,3:4

6Impact of global climate change on the health,welfare and productivity of intensively housed livestock显示文摘Major scientific studies have shown that global warming(i.e.increasing average temperature of the Earth)is now a reality.The aims of this paper are to broadly review the underlining causes of global warming,the general effects of global warming on social and environmental systems and the specific effects of resulting from global warming phenomena severe fluctuations in weather patterns,particularly heat waves on livestock health,welfare and productivity.Finally this article aims to summarise some common sense climate control methods and more importantly to highlight the required future research and development(R&D)work that is necessary to achieve a new level of building environment control capability,and thus ensure that the intensive livestock industries will be able to cope with the changed external climate.With the increasing temperatures on a global scale,the most direct effect of the high temperature on the animals is heat stress,which has been proven to have a variety of negative effects on animal health,welfare and productivity.Different potential measures could be taken in future to alleviate the increased heat stress.Some of these measures are mere adaptations or improvements of current engineering solutions.However,facing the complex challenges of global warming and particularly resulting from it the rapid increase of the number of consecutive days with significantly higher than average temperatures will probably require novel solutions,including new designs based on solid engineering judgment,development of new engineering standards and codes to guide designs,the exploration of new and superior building materials,the need for better energy management,and the development of substantially more“intelligent”control systems that will balance changing exterior disturbances,interior building loads and demands to the biological needs of the occupants of the structures.Tadeusz Kuczynski Victoria Blanes-Vidal Baoming Li Richard S.Gates Irenilza de Alencar Nääs Daniella J.Moura Daniel Berckmans Thomas M.Banhazi 2011International Journal of Agricultural and Biological Engineering2011,4,2:3
