Alveolar regenerative gene expression is unidentified partly because its onset, after a regenerative stimulus, is unknown. Toward addressing this void, we used a mouse model in which calorie restriction produces alveolar loss, and ad libitum access to food after calorie restriction induces alveolar regeneration. We selected four processes (cell replication, angiogenesis, extracellular matrix re...

OBJECTIVE Exposure to high-calorie foods may promote overeating by stimulating brain reward pathways and appetite. Abdominal fat has particularly adverse metabolic consequences and may alter brain pathways that regulate feeding behavior. Functional magnetic resonance imaging (fMRI) was used to test the hypothesis that high-calorie food cues activate brain reward regions and increase appetite, a...

BACKGROUND Calorie labeling at the point-of-purchase in chain restaurants has been shown to reduce energy intake. OBJECTIVE To investigate the impact of point-of-purchase calorie information at one rural middle school. METHODS With a community-based participatory research framework a mixed method approach was used to evaluate the impact of point-of-purchase calorie information. Students in ...

Nutrition labels are one strategy being used to combat the increasing prevalence of overweight and obesity in the United States. The Patient Protection and Affordable Care Act of 2010 mandates that calorie labels be added to menu boards of chain restaurants with 20 or more locations. This systematic review includes seven studies published since the last review on the topic in 2008. Authors sear...

BACKGROUND/OBJECTIVES To encourage healthier food choices for children in fast-food restaurants, many initiatives have been proposed. This study aimed to examine the effect of disclosing nutritional information on parents' meal choices for their children at fast-food restaurants in South Korea. SUBJECTS/METHODS An online experimental survey using a menu board was conducted with 242 parents of...

In the present investigation we researched the effects of low calorie diet without protein restriction on the renal function and glomerular injury of uninephrectomized spontaneously hypertensive rats. We compared the findings with those that occurred in two different groups of uninephrectomized spontaneously hypertensive rats: one treated with oral hydralazine (10 mg/kg per day) and a second fe...

Anticancer drugs have been reported to damage the intestinal mucosa. We evaluated the effects of caloric intake on the mucosal morphology and immune cells in rats treated with 5-fluorouracil (5-FU). Rats were received a liquid diet plus 5-FU treatment for 8 days as follows: Low calorie group (25 kcal/day with 5-FU), Normal calorie group (50 kcal/day with 5-FU), and Control group (50 kcal/day wi...

BACKGROUND Surgery is the only effective treatment for people with a body mass index (BMI) greater than 40 Kg/m² or even greater than 35 Kg/m² when some diseases like diabetes or hypertension appear. In order to minimize surgical risk and improve postoperative results, preoperative preparation it's very important. "Acute" preoperative weight loss just before surgery plays a crucial role in that...

The aim of this article was to study the effect of virtual-reality exposure to situations that are emotionally significant for patients with eating disorders (ED) on the stability of body-image distortion and body-image dissatisfaction. A total of 85 ED patients and 108 non-ED students were randomly exposed to four experimental virtual environments: a kitchen with low-calorie food, a kitchen wi...

BACKGROUND The loss of self-control or inability to resist tempting/rewarding foods, and the development of less healthful eating habits may be explained by three key neural systems: (1) a hyper-functioning striatum system driven by external rewarding cues; (2) a hypo-functioning decision-making and impulse control system; and (3) an altered insula system involved in the translation of homeosta...
