INTRODUCTION A pilot intervention was conducted to promote physical activity and nutrition in public preschool education (near half a million children in Chile), in order to prevent obesity. OBJECTIVE To assess the primary (body fat) and secondary outcomes (physical activity and energy intake) of a nutrition and physical activity pilot intervention for preschool children, attending day care c...

The TRIX index used for the assessment of trophic status of coastal waters has been applied in many European seas (Adriatic, Tyrrhenian, Baltic, Black Sea, and North Sea). However, all these waters are characterized by high nutrient levels and phytoplankton biomass; index calibration based on systems that are principally eutrophic may introduce bias to the index scaling. In the present work the...

A large variety of aquatic animals was found to emit the potent greenhouse gas nitrous oxide when nitrate was present in the environment. The emission was ascribed to denitrification by ingested bacteria in the anoxic animal gut, and the exceptionally high N(2)O-to-N(2) production ratio suggested delayed induction of the last step of denitrification. Filter- and deposit-feeding animal species s...

The present study deals with an account of the primary productivity and trophic status Rewalsar, Kuntbhyog, Prashar lakes Western Himalayas. Seasonal variations in gross (GPP) (g C m –2 day –1 ), net (NPP, respiration (R), NPP/R ratio have been studied compared hydrobiological factors. Among various factors, temperature, light, nutrients, chlorophyll a were accountable for high productivity. Ny...

A research report from the Swedish Environmental Advisory Council, titled A Strategy for Ending Eutrophication of Seas and Coasts, argues that the Baltic Sea is facing an ecological flip, associated with changes characterized by excessive algal bloom and a fishing industry in crisis (MVB 2005). Eutrophication may be the most severe of the consequences faced by the Baltic Sea. According to HELCO...

OBJECTIVE To assess and compare the respiratory muscle strength among eutrophic, overweight and obese school children, as well as to identify anthropometric and respiratory variables related to the results. METHODS Cross-sectional survey with healthy schoolchildren aged 7-9 years old, divided into three groups: Normal weight, Overweight and Obese. The International Study of Asthma and Allergi...

We analyzed Chlorophyll-a and CDOM dynamics from field measurements and 17 assessed the potential of multispectral satellite data for retrieving water-quality parameters in 18 three small surface reservoirs in the Brazilian semiarid region. More specifically, this work 19 comprises i) analysis of Chl-a and trophic dynamics; ii) characterization of CDOM; iii) estimation 20 of Chl-a and CDOM from...

Although the emission of N(2) via anaerobic ammonium oxidation (anammox) is a key process in the elimination of nitrogenous compounds from aquatic environments, little information is available regarding its significance and the relevant microorganisms (anammox bacteria) in eutrophic freshwater lakes. In the present study, the anammox bacteria in the sediment of a eutrophic lake in Japan, Lake K...

BACKGROUND Obesity is associated with the rise of noncommunicable diseases worldwide. The pathophysiology behind this disease involves the increase of adipose tissue, being inversely related to adiponectin, but directly related to insulin resistance and metabolic syndrome (MetS). Therefore, this study aimed to determine the relationship between adiponectin levels with each component of MetS in ...
