Characterizing the Interaction between Root-knot Nematodes and Soil-borne Fungi which are Pathogenic to Passion Fruit ().

For decades there have been anecdotal claims of synergistic interactions between plant-parasitic nematodes and soil-borne fungi causing decline of productivity of passion fruit () orchards. An empirical confirmation of these disease complexes would impact disease management and plant breeding for resistance. To test those claims, we subjected passion fruit plants to single or concomitant parasitism by or and or sp.

The association between caffeine consumption and objective sleep variables is dependent on ADORA2A c.1083T>C genotypes.

Objective: To verify the association between c.1083T>C polymorphism in the adenosine receptor A gene (ADORA2A) and objective sleep, as well as the correlation between caffeine consumption, sleep parameters, and electroencephalographic spectral power in a large, population-based sample from São Paulo, Brazil.

Methods: This study was conducted in participants of the São Paulo Epidemiologic Sleep Study (EPISONO), a large, population-based survey consisting of a representative sample of the inhabitants of the city from São Paulo, Brazil, according to sex, age (20-80 years), and socioeconomic status in the year 2007.

Children's Exposure to Radon in Nursery and Primary Schools.

The literature proves an evident association between indoor radon exposure and lung cancer, even at low doses. This study brings a new approach to the study of children's exposure to radon by aiming to evaluate exposure to indoor radon concentrations in nursery and primary schools from two districts in Portugal (Porto and Bragança), considering different influencing factors (occupation patterns, classroom floor level, year of the buildings' construction and soil composition of the building site), as well as the comparison with IAQ standard values for health protection. Fifteen nursery and primary schools in the Porto and Bragança districts were considered: five nursery schools for infants and twelve for pre-schoolers (seven different buildings), as well as eight primary schools.

Gender-related associations of genetic polymorphisms of α-adrenergic receptors, endothelial nitric oxide synthase and bradykinin B2 receptor with treadmill exercise test responses.

Background: Treadmill exercise test responses have been associated with cardiovascular prognosis in individuals without overt heart disease. Neurohumoral and nitric oxide responses may influence cardiovascular performance during exercise testing. Therefore, we evaluated associations between functional genetic polymorphisms of α-adrenergic receptors, endothelial nitric oxide synthase, bradykinin receptor B2 and treadmill exercise test responses in men and women without overt heart disease.

Spontaneous closure of post-intervention left anterior descending coronary pseudoaneurysm.

Coronary pseudoaneurysms are an unusual finding during coronary angiography and there are very little data on their prognosis in the literature. We report the case of a 62-year-old man admitted with an anterior myocardial infarction who developed a pseudoaneurysm in the mid left anterior descending artery some days after a type I coronary perforation during coronary angioplasty. Spontaneous closure of the pseudoaneurysm was observed during hospital follow-up.

High-sensitivity C-reactive protein levels and treadmill exercise test responses in men and women without overt heart disease.

Background: C-reactive protein (CRP) is a marker of systemic inflammatory activity and may be modulated by physical fitness. Treadmill exercise testing is used to evaluate cardiovascular health through different variables including exercise capacity, heart rate and blood pressure responses. It was hypothesized that CRP levels are associated with these variables in men and women without overt heart disease.

Heart rate response and chronotropic incompetence in exercise stress testing of asymptomatic women.

Evaluation of: Gulati M, Shaw LJ, Thisted RA, Black HR, Bairey Merz CN, Arnsdorf MF: Heart rate response to exercise stress testing in asymptomatic women: The St. James Women Take Heart Project. Circulation 122, 130-137 (2010).

Influence of demographic and metabolic variables on forearm blood flow and vascular conductance in individuals without overt heart disease.

Purpose: Vascular reactivity is involved in the regulation of vascular function either in normal conditions or in the pathophysiology of cardiovascular diseases. We tested the hypothesis that vascular reactivity evaluated by forearm blood flow may vary according to demographic and metabolic variables in a cohort of individuals without any evidence of heart disease after clinical examination.

Subjects And Methods: We studied 186 individuals (mean age 41.
