OBJECTIVE: The aim of this study was to uncover the mediators and mechanistic events that facilitate the browning of white adipose tissue (WAT) in response to burns. BACKGROUND: In hypermetabolic patients (eg, burns, cancer), the browning of WAT has presented substantial clinical challenges related to cachexia, atherosclerosis, and poor clinical outcomes. Browning of the adipose tissue has recently been found to induce and sustain hypermetabolism. Although browning appears central in trauma-, burn-, or cancer-induced hypermetabolic catabolism, the mediators are essentially unknown...

Artificial skin has achieved considerable therapeutic results in clinical practice. However, artificial skin treatments for wounds in diabetic patients with impeded blood flow or with large wounds might be prolonged. Cell-based therapies have appeared as a new technique for the treatment of diabetic ulcers, and cell-sheet engineering has improved the efficacy of cell transplantation. A number of reports have suggested that adipose-derived stem cells (ASCs), a type of mesenchymal stromal cell (MSC), exhibit therapeutic potential due to their relative abundance in adipose tissue and their accessibility for collection when compared to MSCs from other tissues...

It has been shown that adipose tissue and skeletal muscles of lean individuals respond to meal-induced hyperinsulinemia by increases in perfusion, the effect not observed in patients with metabolic syndrome. In conditions of hyperglycaemia and hypertriglyceridemia, this insufficient vascularization leads to the liberation of reactive oxygen species, and disruption of nitric oxide synthesis and endothelial signalling responsible for the uptake of circulating fatty acids, whose accumulation in skeletal muscles and adipose tissue is widely associated with impairment of insulin signalling...

With the increase in obesity worldwide, its associated comorbidities, including nonalcoholic steatohepatitis (NASH), have become a public health problem that still lacks effective therapy. We have previously reported that mixed-lineage kinase 3-deficient (MLK3-deficient) mice are protected against diet-induced NASH. Given the critical need to identify new therapeutic agents, we sought to examine whether the small-molecule MLK3 inhibitor URMC099 would be effective in reversing diet-induced murine NASH. C57BL/6J mice were fed either a diet high in saturated fat, fructose, and cholesterol (FFC), or a chow diet for 24 weeks...

The rise of follicle-stimulating hormone (FSH) is a hallmark of menopause associated with osteoporosis and visceral adiposity. In Nature, Zaidi and colleagues (Liu et al., 2017) report that blocking FSH action reduces body fat by promoting brown/beige fat thermogenesis, potentially providing a new intervention for the treatment of menopause-related metabolic diseases.

Cachexia, a progressive weight loss in cancer patients that results from tumor-induced energy wasting, is a serious problem that interferes with response to treatment and affects quality of life. Recent studies suggest that thermogenesis of adipose tissues is involved in energy wasting and also point to a link between the atrophy of fat and muscle. Tumor-derived PTHrP has emerged as a key molecule playing multiple roles in cachexia, from fat 'browning' factor to potential therapeutic target.

BACKGROUND: Diet and activity are thought to worsen with urbanization, thereby increasing risk of obesity and chronic diseases. A better understanding of dietary and activity patterns across the urbanization divide may help identify pathways, and therefore intervention targets, leading to the epidemic of overweight seen in low- and middle-income populations. Therefore, we sought to characterize diet and activity in a population-based study of urban and rural residents in Puno, Peru. METHODS: We compared diet and activity in 1005 (503 urban, 502 rural) participants via a lifestyle questionnaire...

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a major risk factor for cardiovascular disease, and the prevalence has increased significantly in recent decades to epidemic proportions in China. Individually, fenugreek (Trigonella foenum graecum) seed, mulberry (Morus alba L.) leaf and American ginseng (Panax quinquefolius) root can improve glycemia in various animal models and humans with impaired glucose metabolism and T2DM. The aim of this study was to design an optimized botanical formula containing these herbal extracts as a nutritional strategy for the prevention of insulin resistance and T2DM...

CONTEXT: Intraosseous (IO) access is an established route of administration in resuscitation situations. Patients with serious poisoning presenting to the emergency department may require urgent antidote therapy. However, intravenous (IV) access is not always readily available. OBJECTIVE: This study reviews the current evidence for IO administration of antidotes that could be used in poisoning. The primary outcome was mortality as a surrogate of efficacy. Secondary outcomes included hemodynamic variables, electrocardiographic variables, neurological status, pharmacokinetics outcomes, and adverse effects as defined by each article...

Here, we review and update the recent advances in the metabolic control during the adaptive response of budding yeast to hyperosmotic and salt stress, which is one of the best understood signaling events at the molecular level. This environmental stress can be easily applied and hence has been exploited in the past to generate an impressively detailed and comprehensive model of cellular adaptation. It is clear now that this stress modulates a great number of different physiological functions of the cell, which altogether contribute to cellular survival and adaptation...

Nuclear receptors Farnesoid X Receptor (FXR) and Small Heterodimer Partner (SHP) are important regulators of bile acid, lipid and glucose homeostasis. Here we show that global Fxr (-/-) Shp(-/-) double knockout (DKO) mice are refractory to weight gain, glucose intolerance and hepatic steatosis when challenged with high-fat diet. DKO mice display an inherently increased capacity to burn fat and suppress de novo hepatic lipid synthesis. Moreover, DKO mice are also very active and that correlates well with the observed increase in Pepck expression, type IA fibers and mitochondrial function in the skeletal muscle...

Obesity is associated with low-grade inflammation. Leptin, a hormone made by fat cells regulates appetite and hunger and thus food intake behavior. Interestingly, , food preservatives like sodium sulfite and sodium benzoate and also natural colorant and spice compounds such as curcumin were found to decrease the release of leptin in murine 3T3-L1 adipocytes, after co-incubation with LPS, which was added to mimic the pro-inflammatory status in obesity. Several of these compounds are well known food antioxidants...

Obesity and overweight have become a leading health problem in the world. But we have not yet had any optimal therapy to prevent this health issue. Accumulating evidence suggests that there is existence of functional brown/brite adipocytes in both infants and adult humans, and the activated brown/brite can burn energy by generating heat. These adipocytes can be differentiated from stem cells and transplantation of pre-activated human thermogenic adipocytes in vitro benefits to glucose homeostasis, insulin sensitivity and reduces body fat in normal or obese immunodeficient mice...

AIMS: Depressive symptoms are commonly reported by haemodialysis (HD) patients. Previous reports have suggested an association between depression and nutritional status. To investigate this, we measured muscle mass in HD patients screened for depression. METHODS: The Beck Depression Inventory-II (BDI-II), Hospital Anxiety and Depression Scale (HADS) were used to screen for depression, and quality of life assessed by the short form 36 (SF36), and measured appendicular lean mass (ALM) post-dialysis with segmental bioimpedance...
