BACKGROUND The acute blood pressure response to physical exertion has been used as an indicator of the risk of developing hypertension. The factors associated with this response need to be clarified for timely intervention in preventing hypertensive disease. OBJECTIVE To describe the response of cardiovascular variables to acute physical exertion in overweight adolescents using cardiopulmonar...

The most common natural disturbances in shallow lakes are wind-induced waves, which cause catastrophic changes in the aquatic fauna of lakes. Recovery from these changes is always prolonged. The objective of this study was to understand the resilience and recovery of the particle-attached bacterial community composition (PABCC) after frequent wind-wave disturbance in a large shallow eutrophic l...

OBJECTIVE The aim of this study was to evaluate the multisegmental static postural balance of active eutrophic and obese elderly women using a three-dimensional system under different sensory conditions. METHODS A cross-sectional study was conducted on 31 elderly women (16 eutrophic and 15 obese) aged 65 to 75 years. The following anthropometric measurements were obtained: weight, height, wai...

Algal blooms have been frequently found at the upper reaches of the Tanglang River, which is downstream from the eutrophic Dianchi Lake. The eutrophic lake upstream is considered to be a potential source of phytoplankton, which contributes to the development of harmful algal blooms in the river downstream and can cause many serious problems for the river ecology. However, few studies focused on...

Toxin-producing cyanobacteria have frequently been hypothesized to limit the ability of herbivorous zooplankton (such as Daphnia) to control phytoplankton biomass by inhibiting feeding, and in extreme cases, causing zooplankton mortality. Using limnocorral experiments in hyper-eutrophic ponds located in Alabama and Michigan (U.S.A.), we tested the hypothesis that high levels of cyanobacteria an...

The predictive power of species distribution models (SDMs) varies substantially among depending on their ecological and life-history traits, but which these traits are the most relevant how they influence ‘predictability' remains an area debate. Here, we address questions in bryophytes. SDMs employing macroclimatic, topographic edaphic predictors were calibrated for 411 Europe externally evalua...

Chromophoric dissolved organic matter (CDOM) is crucial in the biogeochemical cycle and carbon of aquatic environments. However, inland waters, remotely sensed estimates CDOM remain challenging due to low optical signal complex conditions. Therefore, developing efficient, practical robust models estimate absorption coefficient waters essential for successful water environment monitoring managem...

BACKGROUND Civilization has produced lifestyle changes; currently, people ingest more calories than are expended, resulting in obesity. This study assessed the association between dietary habits, physical activities, and sedentary behaviors and the risk of obesity in schoolchildren in Mexico City. METHODS Of 1,441 children (6-12 years old) screened in elementary schools, 202 obese (BMI ≥95(th...

Phytoplankton vertical and diel dynamics in a small shallow lake (Lake Monte Alegre, Ribeirão Preto, state of São Paulo) were investigated in two climatological periods: July 2001 (cool-dry season) and March 2002 (warm-rainy season). Monte Alegre is a eutrophic reservoir, with a warm polymictic discontinuous circulation pattern. The lake was thermally stratified in both periods, although dissol...
