Bombesin receptor subtype 3 (BRS-3) is an orphan G-protein-coupled receptor. Based on the obese phenotype of male BRS-3-deficient mice, BRS-3 has been considered an attractive target for obesity treatment. Here, we developed a novel selective BRS-3 agonist (Compound-A) and evaluated its anti-obesity effects. Compound-A showed anorectic effects and enhanced energy expenditure in diet-induced obese (DIO)-F344 rats. Moreover, repeated oral administration of Compound-A for 7 days resulted in a significant body weight reduction in DIO-F344 rats...

Context: Increased prevalence of type 2 diabetes mellitus and prediabetes worldwide has been attributed, at least in part, to a modern lifestyle, in particular, to an unhealthy diet. Objective: To evaluate whether 12 weeks of high MUFA or fiber-rich weight maintenance diet lowers hepatic fat and improves glucose tolerance in people with prediabetes. Design: Subjects underwent a [6, 6-2H2] labeled 75 g oral glucose tolerance test to estimate hepatic insulin sensitivity (Siliver) along with measurement of liver fat fraction (LFF) using magnetic resonance spectroscopy before and after intervention...

Context: Weight loss is prescribed to offset the deleterious consequences of polycystic ovary syndrome (PCOS), but a successful intervention requires an accurate assessment of energy requirements. Objective: Describe energy requirements in women with PCOS and evaluate common prediction equations compared to doubly-labeled water (DLW). Design: Cross-sectional study. Setting: Academic research center. Participants: Twenty-eight weight-stable women with PCOS completed a 14-day DLW study along with measures of body composition, resting metabolic rate, and physical activity assessment by accelerometry...

The hormones ghrelin and leptin act via the lateral hypothalamic area (LHA) to modify energy balance but the underlying neural mechanisms remain unclear. We investigated how leptin and ghrelin engage LHA neurons to modify energy balance behaviors and whether there is any cross-talk between leptin and ghrelin-responsive circuits. We demonstrate that ghrelin activates LHA neurons expressing Hypocretin/Orexin (OX) to increase food intake. Leptin mediates anorectic actions via separate neurons expressing the long form of the leptin receptor (LepRb), many of which co-express the neuropeptide neurotensin (Nts); we refer to these as NtsLepRb neurons...

Bisphenol-A (BPA) is a component of polycarbonate and other plastics to which humans are regularly exposed at low levels. BPA is characterized as an endocrine disruptor due to observations of its estrogenic activity in various experimental models. We have previously shown evidence of disrupted hypothalamic feeding circuitry and leptin sensitivity in adult BPA-exposed animals subject to a high-fat diet, but because these animals were already exhibiting a diet-induced obese phenotype, we could not rule out the possibility that these observations were simply consequences of the obesity, not a pre-existing phenotype produced by BPA exposure...

OBJECTIVE: Behaviour change interventions are effective in supporting individuals to achieve clinically significant weight loss, but weight loss maintenance (WLM) is less often attained. This study examined predictive variables associated with WLM. DESIGN: N-of-1 study with daily ecological momentary assessment combined with objective measurement of weight and physical activity, collected with wireless devices (Fitbit™) for six months. Eight previously obese adults who had lost over 5% of their body weight in the past year took part...

Obesity has grown worldwide over the last few decades. In its different degrees, obesity is accompanied by many clinical and biochemical alterations reflecting the pathological condition of various body tissues. Among the mechanisms underlying the pathogenesis of obesity and associated complications, oxidative stress (OS) may be playing an important role. In the present study, we have characterized at systemic level the degree of OS status in a group of morbid obese patients (BMI>40kg/m(2)) at basal sate and its modulation during one year after bariatric surgery using the laparoscopic sleeve gastrectomy (LSG) technique...

We have investigated the postprandial transcriptional response of blood cells to increasing caloric doses of a meal challenge to test whether the dynamic response of the human organism to the ingestion of food is dependent on metabolic health. The randomized crossover study included seven normal weight and seven obese men consuming three doses (500/1000/1500 kcal) of a high-fat meal. The blood cell transcriptome was measured before and 2, 4, and 6 h after meal ingestion (168 samples). We applied univariate and multivariate statistics to investigate differentially expressed genes in both study groups...

Obesity is characterized by chronic low-grade inflammation driven by activation and tissue infiltration of circulating leukocytes. Although exercise has anti-inflammatory effects, the impact of exercise on mediators of leukocyte migration is unclear. PURPOSE: To determine the impact of high intensity interval training (HIIT) versus moderate intensity continuous training (MICT), in the absence of weight/fat loss, on circulating chemokines and leukocyte chemokine receptors. METHODS: Thirty-seven inactive obese adults were randomized to two weeks (10 sessions) of HIIT or MICT with fasting blood samples collected before and after training...

BACKGROUND: Pancreas grafts from pediatric donors are still considered "not ideal". Perceived concerns are related to low islet mass and potential for graft thrombosis. METHODS: The study evaluated all pancreas transplants from January 2000 to May 2015 using the Organ Procurement and Transplant Network (OPTN) database. Comparative analysis of recipient and graft survival was performed between pediatric (≤18 years) and adult donors. In the pediatric group, the outcomes were stratified based on donor age (≤ 6 years; 7-12 years; 13-18 years) and weight (<30 kg; 30-95 Kg; >95 kg)...

PURPOSE OF REVIEW: Nonpharmacologic lifestyle modification interventions (LMIs), such as increasing physical activity, dietary modification, weight-loss, reducing alcohol consumption and smoking cessation, are effective strategies to lower resting blood pressures (BPs) in prehypertensive or hypertensive patients. However, the limited time shared between a physician and a patient is not adequate to instill an adoption of LMI. The purpose of this review is to therefore highlight evidence-based BP lowering, LMI strategies that can feasibly be implemented in clinical practices...

AIMS: X-linked adrenoleukodystrophy (X-ALD) is a genetic white matter disorder in which demyelination occurs due to accumulation of very long chain fatty acids. Inflammation in the brain white matter is a hallmark of the pathology of cerebral X-ALD, but the underlying pathogenic mechanisms are still largely unknown. In other inflammatory demyelinating disorders such as multiple sclerosis, the expression of heat shock proteins (HSPs) in combination with interferon-γ (IFN-γ) has been suggested to play a prominent role in the initiation of demyelination and inflammation...

REVIEW
Thomas Grenier-Larouche, Anne-Marie Carreau, André C Carpentier
The introduction of bariatric surgery into clinical practice in the 1980s was followed by a relatively long watch-and-wait period before the very rapid accumulation of scientific literature, over the past decade, concerning its clinical effectiveness and safety and its mechanisms of action in the treatment of obesity. These surgical procedures now emerge as the most effective therapeutic modality to induce long-term remission of type 2 diabetes. Recent research has shed light on the potential mechanisms leading to the profound improvement of glucose homeostasis following most bariatric surgery procedures...

Wearable devices, such as smart glasses and watches, allow for continuous recording of everyday life in a real world over an extended period of time or lifelong. This possibility helps better understand the cognitive behavior of humans in real life as well as build human-aware intelligent agents for practical purposes. However, modeling the human cognitive activity from wearable-sensor data stream is challenging because learning new information often results in loss of previously acquired information, causing a problem known as catastrophic forgetting...
