Effect of nutritional density and season on the performance of young rabbit does before the first mating

The objective was to evaluate the effect of nutritional density and season on the performance of young rabbit does before the first mating. Forty-eight females from the Botucatu Genetic Group were used in each season (warm or cool), starting at the age of 70 days, housed in groups of four per cage up to 119 days, and reared individually from 120 to 140 days of age. The high-density diet was formulated to contain, on a 90% DM basis, 18.4% CP, 16.5% ADF and 2,500 kcal DE kg-1; whereas the low-density diet was formulated to contain 14.7% CP, 24% ADF and 2,000 kcal DE kg-1. The experiment was conducted according to a 2x2 factorial design (two diets x two seasons) with repeated measures (weeks). The high-density diet promoted lower feed intake, higher final weight, and higher daily weight gain, adjusted for constant intake. But these facts alone do not warrant using a high-density diet for growing rabbit does, because it could have a negative impact during the reproductive phase. In the warm season, there was a reduction in feed intake and an improvement in feed efficiency. Along time, however, the mean body weight of does was similar in the two seasons.

Risk factors that may signify a propensity to the use of drugs in students at a public university

Introduction: We sought to evaluate the risk factors that may increase the propensity to use licit and illicit drugs among students at a public university. Methods: The project involved students (n = 268) enrolled in the first and fourth years of courses in the areas of the social and biological sciences at a public university. Data collection was conducted by means of self-administered, semistructured questionnaires, based on such standardized assessment instruments as Audit, Assist, Cage and Duse. Collected data were analyzed quantitatively by calculating the percentages and evaluating the data in terms of categories of risk, classifying them by age, gender, religion, schooling, use (before or after entering university) and contexts of use. By means of this survey the researchers were able to correlate the use of drugs to the risk factors that might increase the students’ propensity to use these substances. Results: The results revealed a high proportion of current drug-using students, but showed no significant differences between the first and fourth year students as regards contexts of use. However, 67% of students regarded the university environment as encouraging the use of drugs. Students pointed to such major risk factors as friends’ and fellow-students’ influence, university parties, excessive curiosity and desire to experiment. Conclusion: Due to the high rate of drug use among university students, by the determination of the risk factors related to the university environment and also knowing that the process of addiction is one of growing chemical dependence, the importance of the development and implementation of public health policies at all levels, especially in terms of approaches and specific interventions addressing this population, should be noted.

Efeitos da Fisioterapia Respiratória na Mecânica Respiratória de Pacientes com Acidente Vascular Encefálico Ventilados Mecanicamente

Patients who went through a Stroke may require mechanical ventilation (MV) in the acute phase of the disease and, on MV, they may show alterations in the respiratory mechanic. Physiotherapy techniques are applied in patients on MV to improve their respiratory mechanic. Thus, the purpose of this study was to evaluate the effects of the Respiratory Physiotherapy into the dynamic compliance (Cdyn), static compliance (Cst) and airway resistance (Rwa) in Stroke patients on MV. In order to do that, patients with Stroke diagnostic on MV were evaluated, before and after the use of Physiotherapy techniques (manual rib-cage compression, thoracic decompression, zero end expiratory pressure and suctioning). Cdyn, Cst and Rwa were the researched variables. Statistical Analysis was made using Paired T-Test with statistical significance with p-values no greater than 5%. Eleven patients were part of the study, with an average of 64,6±12,5 years old. Cdyn increased after physiotherapy from 29,3±16,1 ml/cmH2O to 33,8±16,7 ml/cmH2O (p=0,03). Cst also increased from 44,4±20,7 ml/cmH2O to 54,0±26,6 ml/cmH2O (p=0,024). No significant difference was detected for Rwa between the before and after moments (Before – 8,0±3,2 cmH2O/l/s, After – 7,3±2,25 cmH2O/l/s; p=0,45). It was possible to conclude that both dynamic and static compliance increased after physiotherapy, but the airway resistance did not increase in patients with stroke on mechanical ventilation.

Características produtivas e morfológicas do capim Tanzânia em diferentes intensidades de pastejo

The objective of this study was to determine the best height of the Tanzania grass under grazing, assessing morphological and productive characteristics of the sward. This experiment was conducted in Cidade Gaucha, Parana, where he was rated the accumulation rate and morphological characteristics of Tanzania grass pastures grazed at 20, 40, 60 and 80 cm grazing under continuous stocking with variable stocking rate for beef cattle. The experimental area was 12 hectare divided in paddocks of one hectare each. For each paddock were allocated two grazing exclusion cage for estimating herbage accumulation, and eight samples were taken every 28 days throughout the year 2010. The completely randomized design. The herbage mass of the morphological structures showed a linear positive function of sward heights. The height of defoliation did not influence the rate of herbage accumulation for any of the morphological structures: green leaf, stem + sheaths and senescent material. There were also no differences in leaf: stem ratio. All heights within the range studied provided adequate number of green leaves per tiller. Tanzania grass pastures grazed under continuous stocking between 40 and 60 cm, for providing a good association between accumulation and mass of green leaf blades, and acceptable values of the mass of stem + sheaths and senescent material. Pasture of Tanzania grass under 60 and 80 cm allow of leaves satisfactory accumulation in the autumn.

Morbidades e consumo de álcool em pacientes internados na Clínica Médica de um hospital universitário

Abusive consumption of alcohol leads to several negative consequences to health and quality of life, as it increases the frequency of diseases that cause death or functional disabilities. The rates of patients admitted to hospital due to physical problems stemming from alcohol abuse are high. This study aimed at identifying patients according to variables age, gender and education level as well as at evaluating the prevalence of CAGE-positive patients and morbidity due to CID-10 (International Classification of Diseases) by the World Health Organization. It is a cross-sectional, observational, exploratory, descriptive and quantitative study. It was conducted at the Botucatu School of Medicine University Hospital (HC) from July to September 2010, at the Internal Medicine ward. This ward aggregates 5 specialties, namely, Cardiology, Hematology, General Medicine, Nephrology and Gastroclinic. Presently, it has 36 beds, of which four are for Intensive Care Therapy (ICT). Three hundred and ten medical charts were analyzed for identification of morbidities and of variables age, gender and schooling. A closed semistructured questionnaire including, among other questions, the CAGE test was applied to each individual. The CAGE test is a questionnaire that comprises four questions and considers that one who answers two or more of such questions affirmatively is a suspected case of alcoholism. The total population studied included 310 patients. Indexes of 60% (186) male and of 40% (124) female patients were found. As regards age range, a population with a higher prevalence of individuals from 51 to 70 years old (41%) was observed. The main education indexes were: incomplete Elementary School: 23.22% (72), complete Elementary School: 21.61% (67), incomplete Secondary School: 18.40% (57) and Illiteracy: 17.74% (55). As regards diseases, a higher proportion was observed for: ...(Complete abstract click electronic access below)

Comportamento de oviposição em Chrysomya megacephala (F.) (Diptera: Calliphoridae): distinção quantitativa frente a posturas prévias?

Chrysomya megacephala (Fabricius), has considerable medical, veterinary and forensic importance. In insects in general, the ability to track the food substrate is due to highly sensitive organs adapted for detecting odors, particularly in the case of blowflies, which is one of carcass main consumers. Eggs of blowflies are usually aggregated in function of the behavior of other pheromone mediated by females laying eggs in place on the same substrate. One of the main reasons for studying oviposition behavior is because it may indirectly affect individual qualification, population dynamics and community structure. It has been suggested that female blowflies can evaluate the number of eggs on a substrate, decreasing the size of oviposition in very saturated substrates with larvae or eggs leading to a lower intraspecific competition. The present study investigated the oviposition behavior of females of C. megacephala, and wished to consider whether they are able to distinguish quantitatively (size of the mass) eggs previously put into a place of posture and hence indicate whether there is a limit beneficial (to avoid competition among larvae) for its oviposition on the same substrate or if that place would already be saturated, requiring find another substrate without eggs or less for futures ovipositions. With 20 females and five males, five treatments were applied, repeated ten times and analyzed using the Mann-Whitney test. Each treatment consists in placing, inside the cage, a flask with 50g of ground beef and another one in the other side, with the same amount of substrate with a certain amount of prior oviposition for a period of 5 hours. The masses prior eggs were used 0.03 g, 0.05 g, 0.1 g, 0.2 g and 0.3 g (respectively, T1, T2, T3, T4 and T5). The other part of the work consisted in the use of a “Y” olfactometer, a device used to determine the choice of an invertebrate against... (Complete abstract click electronic access below)

Avaliação dos componentes de óleos essenciais 1,8-cineol, β-cariofileno e α-humuleno como possíveis repelentes para Aedes (Stegomyia) aegypti (Diptera: Culicidae)

Aedes aegypti, mosquito da família Culicidae responsável pela transmissão dos vírus da dengue, da febre amarela urbana e da febre chikungunya, apresenta grande proliferação em áreas urbanas das regiões tropicais e subtropicais, além de representar um fator de incômodo por causar alergias devido à inoculação dos componentes salivares durante o processo do repasto sanguíneo. Como forma de evitar os problemas causados por eles, o repelente mais usado e registrado comercialmente desde 1957 é o DEET (N,N-dietil-3-metilbenzamida ou N,N-dietil-meta-toluamida), que apesar de apresentar eficácia comprovada possui determinada toxicidade quando utilizado por crianças e por mulheres grávidas ou lactantes. Atualmente, grande parte dos estudos sobre novas substâncias repelentes envolvem óleos essenciais de plantas, principalmente por serem atóxicos, biodegradáveis, possuírem um preço mais acessível e uma ampla atividade contra diferentes espécies de mosquitos. Os terpenos 1,8-cineol, β-cariofileno e α-humuleno podem ser encontrados em óleos essenciais de uma grande variedade de plantas e apesar de dados da literatura mostrarem uma eficácia dessas substâncias como repelentes para outras espécies de insetos, até o presente momento não existem estudos que relacionam porcentagem de repelência ao longo do tempo para avaliar o potencial de repelência das mesmas para culicídeos.O presente estudo avaliou tais substâncias como possíveis repelentes para A. aegypti, utilizando o DEET como controle positivo. Para avaliar a eficácia do β-cariofileno foi utilizada a BG-cage, uma gaiola desenvolvida especificamente para testes de repelência onde o voluntário expõe um braço sob uma abertura coberta por uma tela onde os mosquitos pousam, mas não picam. Os testes foram repetidos a cada 30 minutos após a aplicação do produto por um tempo máximo de duas horas (seguindo a recomendação de reaplicação do produto comercial ...
