BACKGROUND Experimental and natural human adenovirus-36 (Adv36) infection of multiple animal species results in obesity through increasing adipogenesis and lipid accumulation in adipocytes. Presence of Adv36 antibodies detected by serum neutralization assay has previously been associated with obesity in children and adults living in the USA, South Korea and(More)
This paper and the following four papers summarize a symposium on the role of opioids in regulation of feeding, body weight, and energy expenditure. The central sites of opioid action are discussed, as is opioid activity in invertebrates, large animals, and humans. This paper provides a historical review of developments in the field from the early concepts(More)
The endogenous opiate system is involved in the regulation of numerous bodily functions, but the literature suggests that the effects of endogenous opioids differ among species and between animals and man. Naltrexone, a relatively pure opiate antagonist, appears to have significant effects on the secretion of the gonadotropins (luteinizing hormone and(More)
Obesity is a new specialty of medicine fighting for recognition. Current treatments with diet, exercise, and lifestyle modification have a high failure rate. Few obesity drugs exist and they are not very effective. Research should focus on understanding basic mechanisms, the numerous etiologies of obesity, and new drug development. Understanding the(More)
Massive adipose tissue depositions in the abdomen and thorax sufficient to interfere with respiration developed in a patient with multiple medical problems. Biopsy of adipose tissue identified human adenovirus 36 (Adv 36) DNA. Adv 36 causes adipogenesis in animals and humans. Development of massive lipomatosis may be caused by Adv 36.
