Obesity is frequently associated with insulin resistance and abnormal glucose homeostasis. Recent studies in animal models have indicated that TNF-alpha plays an important role in mediating the insulin resistance of obesity through its overexpression in fat tissue. However, the mechanisms linking obesity to insulin resistance and diabetes in humans remain(More)
BACKGROUND Human adenovirus-36 (Ad-36) increases adiposity and paradoxically lowers serum cholesterol and triglycerides in chickens, mice, and non-human primates. The role of Ad-36 in human obesity is unknown. OBJECTIVES To determine the prevalence of Ad-36 antibodies in obese and nonobese humans. To evaluate the association of Ad-36 antibodies with body(More)
BACKGROUND Human adenovirus-36 (Ad-36) is thought to induce obesity by a direct effect of the viral E4orf1 gene on lipogenic enzymes in host adipocytes. Ad-36 prevalence is 30% in obese adults, but prevalence has not been reported in childhood obesity. OBJECTIVES To determine the prevalence of Ad-36 infection in obese Korean children (age 14.8 +/- 1.9;(More)
Alzheimer disease affects almost 4 million Americans and costs $65 billion annually. The disease is more common in women than in men, and studies suggest that oestrogen may have a protective effect. Oestrogen replacement lowers circulating concentrations of gonadotropins. When gonadotropins are added to rat granulosa cells in culture, the number of low(More)
The effect of 7 wk consumption of a diet containing 32.6% of kilocalories as fat [condensed milk (CM) diet] on body composition and energy intake was evaluated in nine strains of inbred mice (AKR/J, C57L/J, A/J, C3H/HeJ, DBA/2J, C57BL/6J, SJL/J, I/STN, and SWR/J). Control animals were fed a high-carbohydrate diet containing 11.6% of energy as fat (Purina(More)
Because it has been suggested that patients with obstructive sleep apnea have a narrower pharyngeal airway than normal persons, we performed lateral fluoroscopy and computed tomographic (CT) scans of the pharynx in patients with this syndrome. Fluoroscopy in 6 sleeping patients showed that the obstruction always began during inspiration when the soft palate(More)
Conjugated linoleic acid (CLA) is being sold as a panacea that has the capability of reducing or eliminating cancer, preventing heart disease, improving immune function, and altering body composition to treat obesity or build lean body mass. Unfortunately, there has been very little published human research on CLA. This review will examine the literature on(More)
BACKGROUND Four animal models of virus-induced obesity including adiposity induced by an avian adenovirus have been described previously. This is the first report of adiposity induced in animals by a human virus. OBJECTIVE We investigated the adiposity promoting effect of a human adenovirus (Ad-36) in two different animal models. DESIGN Due to the novel(More)
Existing obesity therapies are limited by safety concerns and modest efficacy reflecting a weight loss plateau. Here, we explore combination therapy with bupropion (BUP), a putative stimulator of melanocortin pathways, and an opioid antagonist, naltrexone (NAL), to antagonize an inhibitory feedback loop that limits sustained weight reduction. In vitro(More)
