1. Resistance of sweet potato clones to meloidogyne incognita races 1 and 3
The objective of this study was to evaluate sweet potato clones for resistance to root-knot nematode, Meloidogyne incognita races 1 and 3. For each nematode physiological race, a greenhouse experiment was set up in a randomized block experimental design with three replications and six plants per plot. Fifty-eight sweet potato clones from the UFVJM germplasm

2. Classification of physiological races of Fusarium oxysporum f. sp. phaseoli in common bean
Fusarium wilt, caused by Fusarium oxysporum Schlecht. f. phaseoli Kendrick and Snyder (FOP), is a major disease of common bean, causing large economic losses. Genetic resistance is one of the main mechanisms of pathogen control, and knowledge of the physiological variability is fundamental in breeding for resistant cultivars. Thus, a method of pathogen class

3. Identification of a new race of Hemileia vastratix in Brazil.
In this study, a survey of physiological races of Hemileia vastatrix was carried out on 34 coffee leaf rust populations collected at several coffee genotypes in Brazil. After the inoculation on leaf disc of coffee differential clones, the races I, II, III, XIII, XVII and XXXVII were characterised. This is the first report of race XXXVII on Coffea arabica in

5. Hot spots for diversity of Magnaporthe oryzae physiological races in irrigated rice fields in Brazil.
Abstract ? The objective of this work was to evaluate the Magnaporthe oryzae pathotype diversity in new commercial irrigated rice fields in the Araguaia River Valley, state of Tocantins, Brazil. The causal agent of rice blast has heavily affected rice production in the region. Despite the efforts of breeding programs, blast resistance breakdown has been reco

6. Desempenho e termorregulação de corredores jovens e de meia-idade com VO2 máx similar em corridas de intensidades fixa e autorregulada em ambientes quente e termoneutro
In order to compare the heat exercise performance between middle-aged and young runners with similar VO2peak using self-paced and fixed workload intensity, 26 endurance runners; seven men (MA_M: 54 ± 2 years; 58 ± 4 ml.kg-1.min-1) and six middle-aged women (MA_W: 54 ± 4 years; 48 ± 3 ml.kg-1.min-1); seven men (YO_M: 28 ± 1 years; 61 ± 5 ml.kg-1.min-1)

7. Non genomic actions of triiodothyronine (T3) on the expression polyadenylation and distribution of TSH granules in thyrotrophs of hypothyroid rats / Ações não genômicas da triiodotironina (T3) sobre a expressão, poliadenilação e distribuição dos grânulos de TSH nos tireotrofos de ratos hipotireiodeos
The thyroid-stimulating hormone (TSH) is the main regulator of the synthesis and secretion of thyroid hormones (TH), which exert a negative feedback mechanism in the pituitary by reducing the synthesis of β and α (CGA - Glycoprotein hormones alpha chain) chains through mechanisms that involve changes in the tra

8. O uso do boné em crianças durante a corrida de intensidade auto regulada sob o sol diminui a temperatura média da cabeça, mas não influencia a velocidade da corrida
The aim of this study was to test the hypothesis that the use of the cap could be a barrier to sun radiation, allowing less heat storage during the self paced race of 6 km under sunlight. Nineteen children of both sexes, inhabitants of tropical region, healthy and able to practice physical exercise (10.3 ± 0.7 and 10.2 ± 1.0 years old, 148 ± 6 and 145 ±

9. Contribution of different energy systems for rowing on the water and on different rowing ergometers / Contribuição dos sistemas energéticos na água e em diferentes ergômetros de remo
Rowing is a sport that can be subject to environmental conditions as it is practiced outdoors. Wind, rain and cold climates can disturb or even impede the execution of rowing on the water. For that reason, indoor rowing is considered to be an important means of training. The most used form of indoor training and evaluation of athletes is the rowing ergometer

10. Efeito da dexmedetomidina ou do remifentanil na função renal de pacientes submetidos à cirúrgia bariátrica.
The objective of the present research was to study the comparative effects of dexmedetomidine and remifentanil on the renal function of morbidly obese patients submitted to bariatric surgery. Casuistic and Method: After approval by the local Ethics Council, in the period from August 2004 to August 2005, 61 patients were studied prospectively independent of r

11. Levantamento de Meloidogyne incognita em lavouras de algodÃo no noroeste do Paranà e seleÃÃo de genÃtipos de algodoeiro com resistÃncia a Meloidogyne incognita raÃa 3 / Survey of Meloidogyne incognita on cotton crops in northwest Paranà and selection of resistant cotton genotypes to Meloidogyne incognita race 3
Among the pathogens that reduce the cotton productivity in Brazil, Meloidogyne incognita is one of the most important by causing yield losses and for being widespread. The most recommended control methods to this species are the use of resistant cultivars and crop rotation systems. In ParanÃ, M. incognita races 3 and 4 have already been reported as cotton p

12. IdentificaÃÃo de raÃas do nematÃide de cisto da soja [Heterodera glycines (Ichinohe)] a partir de populaÃÃes de campo e isolados monocÃsticos e resistÃncia de cultivares comerciais à raÃa 3 / Race identification of the soybean cyst nematode (SCN) Heterodera glycines (Ichinohe) from field populations and monocystic isolates and resistance of commercial cultivars to race 3
O nematÃide de cisto à um dos principais patÃgenos da cultura da soja a nÃvel mundial. No Brasil, este nematÃide encontra-se disseminado em praticamente todas as regiÃes produtoras de soja, sendo responsÃvel por perdas de produtividade variÃveis, dependendo do nÃvel de infestaÃÃo a campo. No ParanÃ, esta espÃcie encontra-se amplamente distribuÃ
