REVIEW
C Foster, J B Moore, C R Singletary, J A Skelton
Targeting physical inactivity in children is pertinent to aiding in the decrease of childhood obesity rates. Only 33% of adolescents are obtaining the recommended goal of at least 60 min of physical activity per day. The objectives of this review are to summarize professional recommendations for physical activity and exercise in children and adolescents, and identify family-centred strategies that can be implemented by weight management clinicians. Clinically oriented recommendations and policy statements from professional organizations were identified through literature and internet searches, summarized using rubrics of aerobic, muscle strengthening and bone strengthening exercise, then examined for details on family-based focus, inclusion of child developmental stage and age, and application to the prevention and treatment of obesity...

REVIEW
David E Cummings, Francesco Rubino
Several bariatric operations originally designed to promote weight loss have been found to powerfully treat type 2 diabetes, causing remission in most cases, through diverse mechanisms additional to the secondary consequences of weight loss. These observations have prompted consideration of such operations as 'metabolic surgery', used expressly to treat diabetes, including among patients who are only mildly obese or merely overweight. Large, long-term observational studies consistently demonstrate that bariatric/metabolic surgery is associated with reductions in all cardiovascular risk factors, actual cardiovascular events, microvascular diabetes complications, cancer and death...

A 60-day feeding trial was conducted to evaluate the nutritional potential of fermented Jatropha kernel meal (FJKM) in the diets of rohu, Labeo rohita, fingerlings. Four iso-nitrogenous (336 g kg-1) and iso-energetic (20 MJ kg-1) diets containing 0, 100, 200, and 300 g kg-1 FJKM in replacement of 0, 33.3, 66.7, and 100% soybean meal protein, respectively, were prepared and designated as control, T1, T2, and T3, respectively. A total of 180 acclimatized fish (average weight 6.05 ± 0.04 g) were equally distributed into four experimental groups in triplicates, and were fed their respective diets to satiation twice daily at 10:00 h and 18:00 h...

Since the early 1990s, it has been recognized that testosterone (T) levels are lower in men with type 2 diabetes mellitus (T2DM) compared with nondiabetic men (controls). Hypogonadism has been reported in approximately 50% of men with T2DM with robust correlations with measures of obesity, such as waist circumference and body mass index (BMI). In longitudinal studies, hypogonadism has been identified as a predictor of incident T2DM. Experimental withdrawal of T led to acute decreased insulin sensitivity, which can be reversed by normalization of T concentrations...

Obesity and metabolic syndrome display disparate prevalence and regulation between males and females. Human, as well as rodent, females with regular menstrual/estrous cycles exhibit protection from weight gain and associated chronic diseases. These beneficial effects are predominantly attributed to the female hormone estrogen, specifically 17β-estradiol (E2). E2 exerts its actions via multiple receptors, nuclear and extranuclear estrogen receptor (ER) α and ERβ, and the G-protein-coupled estrogen receptor (GPER, previously termed GPR30)...

Estrogens play essential roles in suppressing food intake and preventing body weight gain. Tremendous research efforts have been focused on estrogen physiology in the context of feeding control. Estrogen receptors and the related signals have been attractive targets for development of new obesity therapies. This chapter focuses on the functional interactions between brain estrogens and other appetite-regulatory signals, the critical estrogen receptor isoforms and distinct brain regions that mediate effects of estrogens on feeding, and the intracellular signals that are involved...

Physiologically, estrogens carry out a myriad of functions, the most essential being the regulation of the reproductive axis. Currently, it is also dogmatic that estrogens play an important role modulating energy balance and metabolism. In this sense, it is well known that low estrogens levels, occurring due to ovarian insufficiency, in conditions such as menopause or ovariectomy (OVX), are associated with increased food intake and decreased energy expenditure, leading to weight gain and obesity at long term...

Our understanding of the metabolic roles of sex steroids in men has evolved substantially over recent decades. Whereas testosterone once was believed to contribute to metabolic risk in men, the importance of adequate androgen exposure for the maintenance of metabolic health has been demonstrated unequivocally. A growing body of evidence now also supports a critical role for estrogens in metabolic regulation in men. Recent data from clinical intervention studies indicate that estradiol may be a stronger determinant of adiposity than testosterone in men, and even short-term estradiol deprivation contributes to fat mass accrual...

Leptin, the adipocyte-derived hormone identified in 1994 for its major role in the control of satiety and body weight regulation, is an adipokine secreted in a sex-specific manner. Although it has clearly been established that females secrete three to four times more leptin than males and that this sexual dimorphism in leptin secretion is exacerbated with overweight and obesity, the origin and the physiological consequences of this sexual dimorphism remain ill-defined. The adipose tissue is the major site of leptin secretion; however, leptin receptors are ubiquitously expressed, conferring to leptin, and indirectly to the adipose tissue, a potential role in the control of numerous physiological functions...

BACKGROUND/AIMS: Myostatin is known as a powerful negative regulator of muscle growth playing a key role in skeletal muscle homeostasis. Recent studies revealed that myostatin-deficient mice lead to an increase of insulin sensitivity, a decrease of adiposity and a resistance to obesity, showing that myostatin can also impact on metabolism. Thus, myostatin appeared as a potential therapeutic target to treat insulin resistance. METHODS: We generated transgenic mice overexpressing Gasp-1, a myostatin inhibitor...

Tanzila Khan, H Christopher Frey
U.S. light duty vehicles are subject to the U.S. Environmental Protection Agency (EPA) emission standards. Emission compliance is determined by certification testing of selected emissions from representative vehicles on standard driving cycles using chassis dynamometers. Test results are also used in many emission inventories. The dynamometer based emission rates are adjusted to provide the certification levels (CL), which must be lower than the standards for compliance. Although standard driving cycles are based on specific observations of real-world driving, they are not necessarily real-world representative...

BACKGROUND: Improved imaging methods are critical to assess neurodegeneration and remyelination in multiple sclerosis. Chronic hypointensities observed on T1-weighted brain MRI, "persistent black holes," reflect severe focal tissue damage. Present measures consist of determining persistent black holes numbers and volumes, but do not quantitate severity of individual lesions. OBJECTIVE: Develop a method to differentiate black and gray holes and estimate the severity of individual multiple sclerosis lesions using standard magnetic resonance imaging...

The increasing worldwide incidence of colon cancer has been linked to obesity and consumption of a high-fat Western diet. To test the hypothesis that a high-fat diet (HFD) promotes colonic aberrant crypt (AC) formation in a manner associated with gut bacterial dysbiosis, we examined the susceptibility to azoxymethane (AOM)-induced colonic AC and microbiome composition in C57/BL6 mice fed a modified AIN93G diet (AIN, 16% fat, energy) or an HFD (45% fat, energy) for 14 weeks. Mice receiving the HFD exhibited increased plasma leptin, body weight, body fat composition and inflammatory cell infiltration in the ileum compared with those in the AIN group...
