10 patients with anorexia nervosa were compared with controls with normal weight, regarding their peripheral blood polymorphonuclear (PMN) granulocyte reactions. The anorexia patients showed a statistically significant decrease in PMN bactericidal capacity and PMN adherence. The mean chemotaxis did not differ, but in two of the anorexia patients chemotaxis was almost absent. The intracellular a...

BACKGROUND Anorexia nervosa is a primary psychiatric disorder, with non-negligible rates of mortality and morbidity. Some of the related alterations could participate in a vicious cycle limiting the recovery. Animal models mimicking various physiological alterations related to anorexia nervosa are necessary to provide better strategies of treatment. AIM To explore physiological alterations an...

INTRODUCTION Interleukin-7 (IL-7) is a cytokine involved in energy homeostasis as demonstrated in rodents. Anorexia nervosa is characterized by restrained eating behavior despite adaptive orexigenic regulation profile including high ghrelin plasma levels. Constitutional thinness is a physiological condition of resistance to weight gain with physiological anorexigenic profile including high Pept...

as the first case, a baby red eared slider turtle, trachemys scripta elegans, 1.77 inches long, with a 4 month history of anorexia and blind eyes was referred to the aquatic animal clinic, school of veterinary medicine, shiraz university, iran. the eyes of the pet were swollen and he was not active in swimming and feeling around. in the clinic, after stress treatment, he was kept in a clean aqu...

BACKGROUND Recent evidence has shown that individuals with acute anorexia nervosa and those recovered have aberrant physiological responses to rewarding stimuli. We hypothesized that women recovered from anorexia nervosa would show aberrant neural responses to both rewarding and aversive disorder-relevant stimuli. METHODS Using functional magnetic resonance imaging (fMRI), the neural response...

Anorexia of aging, defined as a loss of appetite and/or reduced food intake, affects a significant number of elderly people and is far more prevalent among frail individuals. Anorexia recognizes a multifactorial origin characterized by various combinations of medical, environmental and social factors. Given the interconnection between weight loss, sarcopenia and frailty, anorexia is a powerful,...

Animal studies are very useful in detection of early disease indicators and in unravelling the pathophysiological processes underlying core psychiatric disorder phenotypes. Early indicators are critical for preventive and efficient treatment of progressive psychiatric disorders like anorexia nervosa. Comparable to physical hyperactivity observed in anorexia nervosa patients, in the activity-bas...

A population of professional dance (N = 183) and modelling (N = 56) students, who by career choice must focus increased attention and control over their body shapes, was studied. Height and weight data were obtained on all subjects. In addition, a questionnaire that is useful in assessing the symptoms of anorexia nervosa, the Eating Attitudes Test (EAT), was administered. Results of these tests...

Pathological concern regarding one's weight and weight gain is a crucial feature of anorexia nervosa. Consequently, anorexia nervosa patients often claim that they are uncertain regarding the amount of food they should eat. The present study investigated whether individuals with anorexia nervosa show an altered estimation of meal portion sizes and whether this estimation is modulated by an inte...

Systemic inflammatory stimuli cause anorexia and weight loss by disrupting the physiological regulation of energy balance. Mice lacking MyD88, an intracellular mediator of signal transduction activated by Toll-like receptor 4 or IL-1beta receptors, are resistant to anorexia induced by the bacterial endotoxin lipopolysaccharide (LPS), despite a significant circulating cytokine response. Thus, we...
