Abstract: Com o objetivo de avaliar o efeito de diferentes fontes e doses de N e da inocula o com rizóbio na produ o de mudas de Sesbania virgata (sesbania), conduziu-se um experimento no qual se utilizou como substrato composto de baga o de cana-de-a úcar + torta de filtro de usina peneirados (3:2, v:v) e decompostos. Foram testados os seguintes tratamentos em esquema fatorial: 3 doses de N (100, 200 e 300 mg/dm3) x 3 doses de N (uréia, sulfato de am nio e nitrato de am nio) + 2 tratamentos adicionais (inoculado e n o-inoculado com rizóbio). As três aduba es foram realizadas a cada 15 dias, sendo a primeira 30 dias após a semeadura. O experimento foi conduzido sob delineamento inteiramente casualizado, com três repeti es compostas por 80 mudas. As mudas foram avaliadas em altura, diametro, massas de matéria seca da parte aérea e do sistema radicular, área foliar e potencial de regenera o de raízes. Conclui-se que para este substrato a inocula o das sementes foi suficiente para atender à demanda de N das mudas de sesbania.

Abstract: Canine cutaneous leishmaniasis by Leishmania braziliensis is a neglected, but widespread disease of dogs in South America. This paper describes clinical and hematological alterations in 17 L. braziliensis-infected dogs from Brazil. The most common hematological findings were thrombocytopenia (82.4%), anemia (70.6%), low packed cell volume (52.9%) and eosinophilia (41.2%). Twelve (70.6%) dogs displayed at least one evident physical alteration; 11 dogs (64.7%) presented skin lesions, four (23.5%) had weight loss and two (11.8%) onychogryphosis. L. braziliensis-infected dogs present clinical and hematological signs often observed in dogs infected by other pathogens. This indicates that veterinarians and public health workers should not consider the presence of non-specific clinical signs as diagnostic criteria for visceral leishmaniasis in dogs living endemic areas to avoid misdiagnosis and subsequent elimination of dogs infected by L. braziliensis. A leishmaniose cutanea canina causada por Leishmania braziliensis é uma doen a negligenciada, mas disseminada entre c es na America do Sul. Este artigo descreve altera es clínicas e hematológicas em 17 c es infectados por L. braziliensis do Brasil. As altera es hematológicas mais comuns foram trombocitopenia (82,4%), anemia (70,6%), baixo valor de hematócrito (52,9%) e eosinofilia (41,2%). Doze (70,6%) c es apresentaram pelo menos uma altera o física; 11 (64,7%) apresentaram les es cutaneas, quatro (23,5%) perda de peso e dois (11,8%) onicogrifose. C es infectados por L. braziliensis apresentaram altera es clínicas e hematológicas inespecíficas que s o comumente observadas em c es infectados por outros patógenos. Isso indica que veterinários e profissionais de saúde pública n o deveriam considerar a presen a de tais sinais clínicos como critério de diagnóstico para leishmaniose visceral em c es, em áreas endêmicas, no intuito de evitar um diagnóstico equivocado e a subsequente elimina o de c es infectados por L. braziliensis.

Abstract: spontaneous mammary tumors represent the most frequent type of cancer in canines, accounting for approximately 50% of all neoplasms. the majority of scientific papers cited in the literature are limited to non refined epidemiological data, without mentioning the trend of this disease in generating clusters in a given geographical area. in this context, this research aimed to create thematic maps of spatial distribution of mammary neoplasms in bitches and to identify disease clusters for the city of salvador, bahia. trough the spatial analysis scanning, it was found that cases of breast cancer is not evenly distributed in the municipality. a significant primary cluster was detected (p>0,001) covering 67.3% of the studied cases. considering the gap in literature available in this field, it is believed that such results will become very important, especially in leading to new studies, where intrinsic and extrinsic variables regarding the animal must be taken into consideration and analyzed for factors risk identification to formulate educational plans targeting the promotion of animal welfare.

Abstract: there are controversies as to whether extreme ages of women upon giving birth bring with them a greater number of factors associated with infant mortality rates and whether there is evidence of higher mortality rates among children of new mothers below age 20 or over age 34. regarding teenage mothers, a heated debate is in course as to whether adverse obstetric results that occur are due to biological immaturity, to unfavorable socioeconomic situations, or if there is null effect of a woman's young age on the chances of infant mortality. one question involving older mothers at childbirth is whether, despite the inroads made in medicine, this age can be associated with higher vulnerability to infant mortality. another factor is whether more favorable socioeconomic conditions reduce the effect of the most common infirmities seen in mothers who gave birth at age 35 or over. there is also the question as to whether late affects the occurrence of infant mortality. on the basis of contrasting evidence regarding the levels of child mortality as correlated with mothers' age, this article presents and discusses the main arguments found in the literature. in the case of both early and late childbirth, there are indications that back up not only the hypotheses of the biological and socioeconomic plausibility of infant mortality, but also the position that there is no effect of mothers' ages on this factor. two factors hamper more precise identification regarding this vulnerability. first there is the variety of methods used to study the relationship between mother's age when giving birth, on the one hand, and infant mortality, on the other. secondly, there is lack of uniformity among the studies in defining age groups.

Abstract: Background Chagas disease patients with right bundle-branch block (RBBB) have diverse clinical presentation and prognosis, depending on left ventricular (LV) function. Autonomic disorder can be an early marker of heart involvement. The heart rate recovery (HRR) after exercise may identify autonomic dysfunction, with impact on therapeutic strategies. This study was designed to assess the HRR after symptom-limited exercise testing in asymptomatic Chagas disease patients with RBBB without ventricular dysfunction compared to patients with indeterminate form of Chagas disease and healthy controls. Methods One hundred and forty-nine subjects divided into 3 groups were included. A control group was comprised of healthy individuals; group 1 included patients in the indeterminate form of Chagas disease; and group 2 included patients with complete RBBB with or without left anterior hemiblock, and normal ventricular systolic function. A symptom-limited exercise test was performed and heart rate (HR) response to exercise was assessed. HRR was defined as the difference between HR at peak exercise and 1 min following test termination. Results There were no differences in heart-rate profile during exercise between healthy individuals and patients in indeterminate form, whereas patients with RBBB had more prevalence of chronotropic incompetence, lower exercise capacity and lower HRR compared with patients in indeterminate form and controls. A delayed decrease in the HR after exercise was found in 17 patients (15%), 9% in indeterminate form and 24% with RBBB, associated with older age, worse functional capacity, impaired chronotropic response, and ventricular arrhythmias during both exercise and recovery. By multivariable analysis, the independent predictors of a delayed decrease in the HRR were age (odds ratio [OR] 1.11; 95% confidence interval [CI] 1.03 to 1.21; p = 0.010) and presence of RBBB (OR 3.97; 95% CI 1.05 to 15.01; p = 0.042). Conclusions A small proportion (15%) of asymptomatic Chagas patients had attenuated HRR after exercise, being more prevalent in patients with RBBB compared with patients in indeterminate form and controls.
