Overnutrition activates a proinflammatory program in macrophages to induce insulin resistance (IR), but its molecular mechanisms remain incompletely understood. Here, we show that saturated fatty acid and lipopolysaccharide, two factors implicated in high-fat diet (HFD)-induced IR, suppress macrophage CGI-58 expression. Macrophage-specific CGI-58 knockout (MaKO) in mice aggravates HFD-induced g...

Newborn rabbits were overfed by encouraging them to suck from two lactating does. These double-fed rabbits were compared with single-fed litter-mate controls. A standard set of fore- and hind-foot radiographs was obtained by taking daily radiographs from a normal litter and selecting the most representative film to act as a standard for that day. Bone age was assessed in single- and double-fed ...

Background Childhood overnutrition is a serious public health problem, with consequences that extend into adulthood. The aim of this study was to determine the prevalence and determinants of overweight and obesity among school-age children in two urban settings in Ghana. Methods This cross-sectional study involved 3089 children (9-15 years) recruited between December 2009 and February 2012 in...

The phenomenon that adverse environmental exposures in early life are associated with increased susceptibilities for many adult, particularly metabolic diseases, is now referred to as 'developmental origins of health and disease (DOHAD)' or 'Barker' hypothesis. Fetal overnutrition and undernutrition have similar long-lasting effects on the setting of the neuroendocrine control systems, energy h...

Decades of research in rodent models has shown that early postnatal overnutrition induces excess adiposity and other components of metabolic syndrome that persist into adulthood. The specific biologic mechanisms explaining the persistence of these effects, however, remain unknown. On postnatal day 1 (P1), mice were fostered in control (C) or small litters (SL). SL mice had increased body weight...

Metabolic syndrome, a network of medical disorders that greatly increase the risk for developing metabolic and cardiovascular diseases, has reached epidemic levels in many areas of today's world. Despite this alarming medicare situation, scientific understandings on the root mechanisms of metabolic syndrome are still limited, and such insufficient knowledge contributes to the relative lack of e...

Epidemiological studies have shown an association between maternal overnutrition and increased risk of the progeny for the development of obesity as well as psychiatric disorders. Animal studies have shown results regarding maternal high-fat diet (HFD) and a greater risk of the offspring to develop obesity. However, it still remains unknown whether maternal HFD can program the central reward sy...

BACKGROUND Urbanization is increasing around the world, and in India, this trend has translated into an increase in the size of slum dwellings whose environments are suspected of being associated with poor health outcomes, particularly those relating to women's nutritional status. With this study, we sought to determine the factors associated with Indian women's body mass index (BMI) in slum en...

INTRODUCTION Many studies have found that parents of overweight children do not perceive their child to be overweight. Little is known, however, about the extent to which such misperceptions exist among parents of preschool-aged children. METHODS We analyzed data that were collected in 2004-2005 from parents of 593 preschool-aged children in 20 child care centers in the Minneapolis-St. Paul, ...

Results from epidemiogical studies have provided clues as to etiological factors involved in the development of large bowel cancer. Overnutrition, especially in terms of dietary fat consumed, appears to be a key etiological variable affecting the rate of colon cancer. Epidemiologists can provide the leads for chemists and bacteriologists to pursue in population groups and for experimentalists t...
