Obesity: an asthma aggravating factor?
Background Several trials have demonstrated an association between obesity and asthma severity. Body Mass Index (BMI) is a metric used to estimate the amount of body fat. It’s one of the best methods for population assessment of overweight and obesity. We have investigated the relationship between BMI and asthma severity in an adult asthmatic population from the Clinical Immunology outpatient s...
متن کاملThermodynamic modelling predicts energetic bottleneck for seabirds wintering
INTRODUCTION The strong link between animal energetics and individual survival has been put forward in a variety of studies (Schmidt-Hempel and Wolf, 1988; Speakman and Racey, 1989; Hobbs, 1989; Golet et al., 1998; Golet et al., 2000). During reproduction, parental care such as offspring provisioning forces adults to spend energy at a high rate, potentially threatening their own survival (Dijks...
متن کاملThermodynamic modelling predicts energetic bottleneck for seabirds wintering in the northwest Atlantic.
Studying the energetics of marine top predators such as seabirds is essential to understand processes underlying adult winter survival and its impact on population dynamics. Winter survival is believed to be the single most important life-history trait in long-lived species but its determinants are largely unknown. Seabirds are inaccessible during this season, so conventional metabolic studies ...
متن کاملStable isotope evidence of diverse species-specific and individual wintering strategies in seabirds.
Although there is increasing evidence that climatic variations during the non-breeding season shape population dynamics of seabirds, most aspects of their winter distribution and ecology remain essentially unknown. We used stable isotope signatures in feathers to infer and compare the moulting (wintering) habitat of subantarctic petrels breeding at two distant localities (South Georgia and Kerg...
متن کامل[The metabolic syndrome: from an aggravating condition to a pathogenic risk factor for chronic diseases].
In recent years, a rapidly increasing number of studies have focused on the association between metabolic syndrome and several chronic diseases. However, it is difficult to determine a well defined pathogenic relationship, due to the etiological heterogeneity and comorbidities of these diseases. Research efforts are aiming to identify the convergent biological mechanisms that mediate the effect...
