To investigate possible risk factors for Parkinson's disease (PD) we conducted a case-control study of 150 PD patients and 150 age- and sex-matched controls. We interviewed and examined all 300 subjects. We collected demographic data including lifetime histories of places of residence, source of drinking water, and occupations such as farming. Subjects(More)
BACKGROUND AND AIMS A standardized methodology to assess the impacts of land-use changes on vegetation and ecosystem functioning is presented. It assumes that species traits are central to these impacts, and is designed to be applicable in different historical, climatic contexts and local settings. Preliminary results are presented to show its(More)
Land use and climate changes induce shifts in plant functional diversity and community structure, thereby modifying ecosystem processes. This is particularly true for litter decomposition, an essential process in the biogeochemical cycles of carbon and nutrients. In this study, we asked whether changes in functional traits of living leaves in response to(More)
BACKGROUND AND AIMS Fire is the dominant disturbance in central Kamchatka boreal forests, yet patterns and mechanisms of stand recovery have not been investigated. METHODS Measurements were made of 1433 stems > or =1.3 m height and annual radial increments of 225 randomly selected trees in a 0.4-ha plot of a 53-year-old fire-origin mixed-species stand to(More)
We studied the effect of cessation of management on carbohydrate reserves of plants in meadows with different environmental characteristics and plant composition. We recorded storage carbohydrates and seasonal changes for 40 plant species. We asked whether there are differences in responses of carbohydrate reserves in forbs versus graminoids and in plants(More)
Changes in composition and structure of plant communities in relation tothe soil and snow cover variation were analyzed along an altitudinal transect(1150–1750 m) from the mountain-temperate forests to a woodyshrub community and alpine meadows on Mt Velký Gápel', Slovakia.The soils below the treeline (∼1510 m) had a more developedorganic layer above the(More)
Methanogens typically occur in reduced anoxic environments. However, in recent studies it has been shown that many aerated upland soils, including desert soils also host active methanogens. Here we show that soil samples from high-altitude cold deserts in the western Himalayas (Ladakh, India) produce CH4 after incubation as slurry under anoxic conditions at(More)
OBJECTIVES To study the andrological outcome of the division of testicular lymphatic vessels at varicocelectomy in children and adolescents. METHODS Testicular size and basal and stimulated luteinizing hormone (LH) and follicle-stimulating hormone (FSH) values were determined prospectively in 86 patients with left unilateral varicocele grades II-III. 22(More)
An increased incidence of complications of atherosclerosis has been noted in cancer survivors. The aim of the present study was to evaluate, in patients with breast carcinoma, the effect of antracycline-based chemotherapy on carotid intima-media thickness (IMT), myocardial perfusion, assessed by single-photon emission tomography (SPECT) and laboratory(More)
UNLABELLED The objective of the study is to estimate the differences in the impact of diet and physical exercise on lung cancer risk in female nonsmokers vs. smokers, and reveal interactions, if any. In a hospital based case-control study, data collected by in-person interviews from 569 female lung cancer cases and 2120 controls were analyzed using(More)
