BACKGROUND: Atherosclerosis (AS) is the most common and serious complication of type 2 diabetes mellitus (T2DM) and is accelerated via chronic systemic inflammation rather than hyperglycemia. Adipose tissue is the major source of systemic inflammation in abnormal metabolic state. Pro-inflammatory CD4(+)T cells play pivotal role in promoting adipose inflammation. Adipose-derived stem cells (ADSCs) for fat regeneration have potent ability of immunosuppression and restricting CD4(+)T cells as well...

Perineural adherences represent a problem after surgery involving peripheral neural system. Fat-grafting with adipose derived stem cells (ASCs) with their pro-regenerative characteristics can be important to prevent the neural damage or to facilitate the neural regeneration. Our idea was to use the fat-grafting as an anti-adherence device and test its efficacy on a postsurgical scar animal model and comparing to an antiadhesive gel. 32 athymic mice were operated under magnification, we exposed both sciatic nerves...

Experimental bone marrow transplantation (BMT) in mice is commonly used to assess the role of immune cell-specific genes in various pathophysiological settings. The application of BMT in obesity research is hampered by the significant reduction in high-fat diet (HFD)-induced obesity. We set out to characterize metabolic tissues that may be affected by the BMT procedure and impair the HFD-induced response. Male C57BL/6 mice underwent syngeneic BMT using lethal irradiation. After a recovery period of 8 weeks they were fed a low-fat diet (LFD) or HFD for 16 weeks...

BACKGROUND: Cell-assisted lipotransfer has been promisingly applied to restore soft-tissue defects in plastic surgery; however, the harvesting of stromal vascular fraction increases morbidity and poses potential safety hazards. The authors investigated whether adding indomethacin, an antiinflammatory proadipogenic drug, to the fat graft at the time of transplantation would enhance the final graft volume compared with cell-assisted lipotransfer. METHODS: In vitro, human adipose-derived stem cells were cultured in conditioned growth media supplemented with various doses of indomethacin to investigate adipogenesis and the expression of the adipogenic genes...

BACKGROUND: Isolated adipose stem cells have been reported to encourage migration and early metastasis of breast cancer. Mimicking a surgical situation, the authors developed a human breast cancer model to evaluate in vivo whether human adipose tissue promotes tumor growth and invasion. METHODS: Human adipose tissue was obtained from four patients. The MDA-MB-468 cell line was cultured with a lentiviral vector encoding a puromycin resistance gene and mCherry fluorescent protein...

BACKGROUND: Composite breast augmentation with fat grafting and an implant has become very popular in the past 5 years. This achieves the core volume projection of an implant complemented by the natural appearance and feel of fat. However, no study has looked at the complications and reoperation rates of this technique. METHODS: A retrospective chart review examined all patients who underwent the combined use of an implant and fat grafting for primary breast augmentation...

Obesity is characterized by increased fat mass, as adipose tissue serves as a storage site for excess energy from food consumption. In obesity, altered lipid metabolism of adipose tissue, characterized by fatty acid uptake, de novo lipogenesis, and lipolysis, are induced. In this study, we examined the effect of zerumbone, a major sesquiterpene from wild ginger, on high-fat diet (HF)-induced obesity and dysregulated lipid metabolism in the white adipose tissues (WAT) of C57BL/6N mice. Dietary supplementation with zerumbone ameliorated HF-induced obesity and improved impaired lipid metabolism in WAT...

The prevalence of non-alcoholic fatty liver disease is increasing rapidly worldwide. However, effective strategies for combating high-fat diet (HFD) induced obesity, fatty liver and metabolic disorder are still limited, and outcomes remain poor. In the present study, we evaluated the combined actions of dietary capsaicin and antibiotics on HFD-induced physiological abnormalities in mice. C57BL/6 male mice were fed with HFD (60% calories from fat) for 17 weeks, and the resultant pathophysiological effects were examined...

BACKGROUND: In the past decade, the minimally invasive repair of pectus excavatum (MIRPE) has become the treatment of choice for severe pectus excavatum (PE), proving acceptable to excellent cosmetic results. Recently, autologous fat grafting (FG) has been identified in aesthetic and reconstructive surgery to ideally handle volume and contour defects. We report our experience about FG in the treatment of residual minor defects after MIRPE and a proposal for a new indication of this largely adopted technique...

Our previous study demonstrated that thiodigalactoside (TDG) ameliorates obesity by targeted inhibition of galectin-1 (GAL1). Here, for the first time, we report the unexpected role of GAL1 and ATG5 inhibition by TDG in lipid metabolism. Core thermogenic marker proteins and genes were highly induced in white adipose tissue (WAT) of rats fed a high fat diet (HFD) and TDG, resulting in the significant development of brown fat-like adipocytes in inguinal WAT. TDG treatment reduced weight gain and fat mass as well as activated brown adipose tissue (BAT) in HFD-fed rats...

Vaspin and omentin are adipose tissue adipokines that have often been related to obesity and its comorbidities. The aim of this study was to investigate the behaviour of serum omentin and vaspin in models of type 2 diabetes. To do this, Wistar rats (~200 g) were randomly divided into two groups: a non-diabetic group (n = 6) and a diabetic group fed on a high-fat diet (n = 6) and a low dose of streptozotocin (Sigma(®) ). All procedures were approved by the Brazilian Ethics Committee. Body weight (BW) and food intake were recorded daily...

This experiment was carried out to examine the effect of grapeseed oil (GSO) on performance, rumen fermentation, antioxidant status and subcutaneous adipose fatty acid (FA) profile in lambs. Eighteen Baluchi lambs, 196 ± 14 days of age and 39.8 ± 1.7 kg body weight, were randomly assigned to three experimental diets: (i) diet without GSO (control), (ii) diet containing 2% of GSO (GSO2) and (iii) diet containing 4% of GSO (GSO4) for 42 days. Results showed that the experimental diets had no significant effect on dry matter intake and performance (p > 0...

Capsaicin (CAP), the major active component of chili peppers, is known to have thermogenic and weight-loss potential. The aim of this study was to investigate the anti-obesity effects of capsaicin-loaded nanoemulsions (C-NE) on male Sprague Dawley (SD) rats treated with a high-fat diet (HFD). The food grade C-NE was prepared using capsaicin, medium chain triacylglycerols (MCT) (Neobee 1053), sucrose stearate S-370, Tween 80 and distilled water with an emulsion droplet size of 168 nm and a capsaicin loading of 80...

Sn-2 palmitic acid triacylglycerols (sn2PA fat) and polyunsaturated fatty acids are thought to influence the metabolic status and intestinal bacterial population of the host. In this study, the impact of sn2PA fat in combination with DHA or ARA in the diet on lipid metabolism in the liver and faecal microbiota composition were investigated in rats fed diets containing sn2PA fat, 90% sn2PA fat + 10% DHA oil (wt%), or 90% sn2PA fat + 10% ARA oil (wt%). Tissue fatty acid composition was measured using gas chromatography (GC), whereas the faecal microbial composition was assessed using 16S rRNA high-throughput sequencing technology...

Renal replacement lipomatosis (RRL) is a rare condition that occurs at the end of the spectrum of renal tissue replacement by fat. Xanthogranulomatous pyelonephritis (XGP) is a granulomatous inflammation characterized by destruction of renal parenchyma and replacement by lipid-laden macrophages. We present the case of a 75-year-old man who complained of severe anemia 34 years after right nephrolithotomy. Computed tomography revealed a huge low-density mass with renal parenchyma atrophy on the right side of horseshoe kidney...

Depression and use of antidepressant medications are both associated with increased risk of obesity, potentially attributed to a reduced serotonin transporter (SERT) function. However, how SERT deficiency promotes obesity is unknown. Here, we demonstrated that SERT (-/-) mice display abnormal fat accumulation in both white and brown adipose tissues, glucose intolerance and insulin resistance while exhibiting suppressed aromatase (Cyp19a1) expression and reduced circulating 17β-estradiol levels. 17β-estradiol replacement in SERT (-/-) mice reversed the obesity and glucose intolerance, supporting a role for estrogen in SERT deficiency-associated obesity and glucose intolerance...

Browning white adipocytes may be a new target in anti-obesity therapy. Pentamethylquercetin (PMQ) has been shown to have anti-obesity effects in monosodium glutamate-induced obese mice. Here, we aimed to study the anti-obesity effects of PMQ in vitro and in vivo and to determine if adipose browning is involved in the mechanism underlying the anti-obesity effects of PMQ. We evaluated the effects of PMQ on cell proliferation, cell differentiation, glucose consumption, cellular lipid metabolism, and related brown gene expression in 3T3-L1 adipocytes...

Aging affects almost all physiological processes, but changes in body composition and body phenotype are most observable. In this review, we focus on these changes, including loss of bone and muscle and increase in body fat or redistribution of the latter, possibly leading to osteosarcopenic obesity syndrome. We also address low-grade chronic inflammation, prevalent in aging adults and a cause of many disorders including those associated with body composition. Changes in dietary intake and nutritional requirements of older individuals, that all may lead to some disturbances on tissue and organ levels, are discussed as well...

The European isolate Agrotis segetum granulovirus DA (AgseGV-DA) is a slow killing, type I granulovirus due to low dose-mortality responses within seven days post infection and a tissue tropism of infection restricted solely to the fat body of infected Agrotis segetum host larvae. The genome of AgseGV-DA was completely sequenced and compared to the whole genome sequences of the Chinese isolates AgseGV-XJ and AgseGV-L1. All three isolates share highly conserved genomes. The AgseGV-DA genome is 131,557 bp in length and encodes for 149 putative open reading frames, including 37 baculovirus core genes and the per os infectivity factor ac110...
