Estudo morfométrico comparativo de 58 populações brasileiras de Rotylenchulus reniformis (Nemata: Rotylenchulinae)

Foram recuperadas 58 populações de Rotylenchulus reniformis de amostras de solo e raízes de diferentes culturas e inoculadas em plantas de algodoeiro (Gossypium hirsutum) cv. COODETEC 402 e de mamona (Ricinus communis), mantidas em vasos de argila em casa de vegetação do Departamento de Fitossanidade da UNESP/FCAV, Campus de Jaboticabal - São Paulo. Foi realizado estudo morfométrico comparativo das populações ao microscópio óptico composto, seguido da ordenação das populações segundo análises multivariadas de agrupamento e de componentes principais. Foram avaliadas 11 variáveis morfométricas em dez fêmeas jovens de cada população e sete variáveis derivadas. A amplitude de variação de caracteres morfométricos em populações brasileiras desse nematóide tais como, comprimento do estilete, V e forma da cauda, é maior que em populações da mesma espécie de outras regiões do mundo. Os dados obtidos confirmam que o comprimento do estilete, presença de machos e V são suficientes para identificação de R. reniformis e que esta é a espécie do grupo predominante nos agroecossistemas brasileiros.

Análise econômica da alface americana em monocultura e consorciada com pepino japonês em ambiente protegido

The experiment was carried in green house at Unesp, Jaboticabal-SP, in the period of August and November, with objective to evaluate the production cost and crisphead lettuce "Lucy Brown" profitability in monoculture and in intercropping with Japanese cucumber "Hokushin" in protected environment. The production cost determination was performed on total operational cost (COT) basis. The crisphead lettuce in monoculture estimated COT and in intercropping was R$ 657,57 and R$ 159,95/614,4 m(2) respectively. The productivities of 623 and 730 kg/614,4 m(2) in the experiments had provided gross incomes of 286,58 R$ and 335,80/614,4 m(2). It was verified a loss of R$ 370,99/614,4 m(2) in the crisphead lettuce monoculture and an operational profit of R$ 175,85/614,4 m(2), in protected environment when in intercropping with cucumber.

Níveis de fósforo disponível e tamanho de partícula do fosfato bicálcico na dieta de poedeiras comerciais de 24 a 58 semanas de idade

Um experimento foi conduzido para verificar o efeito de níveis de fósforo e do tamanho de partícula do fosfato bicálcico na dieta de poedeiras comerciais na fase de produção. Utilizou-se um delineamento experimental inteiramente casualizado, em esquema fatorial 2 × 3 com dois tamanhos de partícula do fosfato (fino e granulado) e três níveis de fósforo disponível (0,28; 0,38 e 0,48%), totalizando seis tratamentos, cada um com cinco repetições de oito aves. As dietas experimentais foram isoproteicas, isocalóricas e isocálcicas. O consumo de ração, a produção de ovos, a massa de ovos, a conversão alimentar, a porcentagem de casca, a gravidade específica e os teores de cinzas, cálcio, fósforo e magnésio nos ossos não foram afetados pelas dietas. Dietas contendo fosfato bicálcico (fino ou granulado) e 0,28% de fósforo disponível atendem às exigências de fósforo de galinhas poedeiras semipesadas de 24 a 58 semanas de idade.

Cardiovascular fitness and cardiovascular risk factors among obese men and women aged 58 years and older, in Portugal

Background: A better physical fitness may have survival advantages in adults. Aim: To analyze the relationship between cardiorespiratory fitness and cardiovascular risk factors among obese subjects aged 58 years and older. Material and Methods: Cardiorespiratory fitness using the six-minute walk test, body composition by dual-energy x-ray absorptiometry and blood pressure were measured in a non-representative sample of 76 obese Portuguese subjects aged 58 to 87 years (55 women). Participants were stratified in tertiles of walking capacity according to the six-minute walk test. Results: Six minutes walk test results were negatively correlated with percentage body fat (r = -0.28; p = 0.012) and systolic blood pressure (r = -0.23; p = 0.045). Participants located in the lowest tertile for the six minutes walk test had an odds ratio of 4.34 (95% confidence intervals: 1.02-18.43) for elevated blood pressure. Conclusions: A lower six minutes walk test result is associated with a higher risk for high blood pressure. (Rev Med Chile 2012; 140: 1164-1169).

Effects of castration on alpha(1)-adrenoceptor subtypes in the rat aorta

The expression of alpha(1)-adrenoceptor subtypes in several tissues is regulated by gonadal hormones. In this study, we investigated whether castration regulates the alpha(1)-adrenoceptor subtypes mediating the contractions of the aorta from male rats to noradrenaline. Noradrenaline induced similar concentration-dependent contractions in the aorta from control and castrated rats. Treatment of the aorta from both control and castrated rats with the alpha(1B)/alpha(1D)-adrenoceptor alkylating agent chloroethylclonidine resulted in approximate to1600-fold rightward shift in the concentration-response curves to noradrenaline. The pA(2) values found for WB 4101, benoxathian (alpha(1A)-selective) and BMY 7378 (alpha(1D)-selective) indicate that alpha(1D)-adrenoceptors are involved in the contractions of the aorta from control and castrated rats to noradrenaline. However, there was a 15-fold difference between the pK(B) estimated through the lowest effective concentrations of the alpha(1A)-adrenoceptor selective antagonist 5-methyl-urapidil in the aorta from control and castrated rats. The pK(B) estimated in aorta from control rats is consistent with the interaction with alpha(1D)-adrenoceptors (7.58 +/- 0.06), while that calculated in organs from control rats is consistent with alpha(1A)-adrenoceptors (8.76 +/- 0.09). These results suggest that castration induces plasticity in the alpha(1)-adrenoceptor subtypes involved in the contractions of the aorta to noradrenaline. (C) 2003 Elsevier B.V. All rights reserved.

Paracoccidioidomicose: estudo radiológico e pulmonar de 58 casos

Spirometric and haemogasimetric tests were performed in 52 patients with unifocal and multifocal progressive Paracoccidioidomycosis pulmonary diseases, in 5 patients with juvenile and 1 female internal genital forms. The age ranged from 20 to 74 years old and the duration of disease from 3 to 25 years. Dyspnea, cough, tegumentary and lymphatic manifestations were the most predominant signs observed. Fourteen of them was developed Cor pulmonale. Impaired renal function was recorded in 19 patients, cardiac symptoms were described in 7 and hyporeactor adrenal activity was showed in 13 patients. Radiological studies demonstrated mild in 16, moderate in 24 and severe pulmonary lesions types in 18 patients. The pulmonary function revealed: normal spyrographic findings in 17, pure obstructive type in 32 and mixed form in 9 of them. Hyperventilation was described in 54 individuals and all of them showed an increasing of the alveolo-arterial difference. PaO2 less than 80 mm/Hg observed in 36 of them. Statistical analysis demonstrated significative association between clinical evolution and radiological interpretation. Similar data were obtained in radiology evaluations, clinical evolutive studies and pulmonary functions described in these patients. The granulomatous reaction due to Paracoccidioidomycosis, in heavy smokers patients, gave origin to the alterations in small airways predisposing the interalveolar dissemination an impaired alveolo-arterial diffusion.

Análise dos aspectos legais das prescrições de medicamentos

This article describes a survey of prescriptions dispensed in drugstores and pharmacies in the city of Araraquara in the state of São Paulo, Brazil, in May 2006. Their contents were assessed for compliance with the laws in force on drug prescription and dispensing. A total of 1,335 prescriptions were examined: 40 (3%) were unsigned, 212 (15.9%) did not contain the prescribing physician's stamp, 170 (12.7%) were undated. There were prescriptions containing corrections (4.6%), and written in code (4.4%). Only 58.8% were legible and easy to understand; nevertheless all of them were dispensed. Some did not specify the name of the patient (7.2%). On how to use the medication prescribed, not a single prescription contained all the information required by law. Specifically, 7.6% lacked information on dosage, 54.3% on presentation, 33.6% on how to take the drug, and 51.2% on duration of treatment. The data show a general failure to comply with the laws on drug prescription and dispensing. Incomplete information on the drugs and their correct use could lead to irrational use and errors in medication. The lack of prescribers' signature and stamp, date of emission and name of patient can lead to fraudulent and counterfeit prescriptions. Thus, the data found point to the need for capacitation of prescribing and dispensing professionals and the importance of the role of professional associations in guiding their members.
