Effects of dried distillers grains with solubles (DDGS) feeding strategies (a corn-soybean meal (CS) fed continously; CS+40% DDGS fed continously; CS+40, 30, 20, or 10% DDGS in 4 phases, respectively; or CS+40% DDGS in phases 1 to 3 and CS in phase 4 before slaughter) on belly and pork fat quality of immunologically castrated (n=192) pigs were evaluated. All pigs received the first Improvest dose at 11week of age, and the second dose at 9, 7, or 5week before slaughter at 24week of age. Increasing the time interval of the second Improvest dose before slaughter reduced IV in all fat depots and increased belly thickness...

BACKGROUND: Various fat depots including visceral (VAT), subcutaneous adipose tissue (SAT) or liver fat content (LFC) were supposed to have different influences on various entities including adipokine levels as well as insulin resistance/sensitivity. Therefore, the aim of the study was to investigate the associations of SAT, VAT and LFC with the levels of leptin and vaspin as well as insulin resistance in a general non-diabetic population. METHODS: In total, 1825 participants of the Study of Health in Pomerania were characterized according to body fat compartments and LFC determined by magnetic resonance imaging...

We evaluated the effect of frequency, duration and intensity of exercise training on metabolic parameters and structural capillary density in obese rats with metabolic syndrome (MS). Wistar-Kyoto rats were fed a either standard commercial diet (CON) or high-fat diet (HFD). Animals that received the HFD were randomly separated into either a sedentary (SED) group or 8 different exercise groups that varied by the frequency, duration and intensity of training. After 12 weeks of aerobic exercise training, body composition, aerobic capacity, hemodynamic variables, metabolic parameters and capillary density in the heart and skeletal muscle were evaluated...

Adipose tissue includes multiple anatomical depots that serve as an energy reserve that can expand or contract to maintain metabolic homeostasis. During normal growth and in response to overnutrition, adipose tissue expands by increasing the volume of preexisting adipocytes (hypertrophy) and/or by generating new adipocytes (hyperplasia) via recruitment and differentiation of adipose progenitors. This so-called healthy expansion through hyperplasia is thought to be beneficial in that it protects against obesity associated metabolic disorders by allowing for the "safe" storage of excess energy...

Although regular physical activity is associated with improvement in aerobic capacity and lower breast cancer risk, there are heritable sets of traits that affect improvement in aerobic capacity in response to physical activity. Although aerobic capacity segregates risk for a number of chronic diseases, the effect of the heritable component on cancer risk has not been evaluated. Therefore, we investigated breast carcinogenesis in rodent models of heritable fitness in the absence of induced physical activity...

Rhizoma Alismatis (RA) was wildly used for treatment of dysuria, pyelonephritis, hyperlipidemia, enteritis diarrhea, diabetes, inflammation, and cancer. Triterpenoids are the major active components of RA, and its extract is mainly composed of alisol A (ALA), alisol B (ALB), alisol C 23-acetate (ALC-23A), alisol A 24-acetate (ALA-24A), and alisol B 23-acetate (ALB-23A). In this study, a simple, reliable, and sensitive ultra high-performance liquid chromatography with triple quadrupole mass spectrometry (UHPLC-MS/MS) method was created and validated for the quantification of the five major triterpenoids in rat plasma and various tissues biosamples (including intestine, stomach, liver, kidney, fat, muscle, brain, heart, lung, spleen, and testes)...

Adipose tissue development is associated with modifications involving extracellular matrix remodelling, and metalloproteinases play a significant role in this process. Reduced circulating sexual hormones cause impacts on the size, morphology and functions of the adipose tissue, increasing susceptibility to diseases. This study investigated whether exercise training may be an alternative strategy to combat the effects promoted by estrogen decay through modulation in gene expression patterns in the extracellular matrix (ECM) of visceral adipose tissue of ovariectomized rats...

The genomic CDKN2A/B locus, encoding p16(INK4a) among others, is linked to an increased risk for cardiovascular disease and type 2 diabetes. Obesity is a risk factor for both cardiovascular disease and type 2 diabetes. p16(INK4a) is a cell cycle regulator and tumour suppressor. Whether it plays a role in adipose tissue formation is unknown. p16(INK4a) knock-down in 3T3/L1 preadipocytes or p16(INK4a) deficiency in mouse embryonic fibroblasts enhanced adipogenesis, suggesting a role for p16(INK4a) in adipose tissue formation...

The insulin sensitizing glitazone drugs, rosiglitazone (ROS) and pioglitazone (PGZ) both have anti-proliferative and anti-inflammatory effects and induce adipose tissue (fat) to produce the vaso-protective protein adiponectin. Stenosis due to intimal hyperplasia development often occurs after placement of arteriovenous synthetic grafts used for hemodialysis. This work was performed to characterize the in vitro and in vivo effects of ROS or PGZ incorporation in fat and to determine if fat/PGZ depots could decrease vascular hyperplasia development in a porcine model of hemodialysis arteriovenous graft stenosis...

We thank Macchi et al. for their comments regarding our study describing regional differences between perisynovial and infrapatellar adipose tissue (AT) depots in patients with end stage osteoarthritis (OA) of the knee [1]. They summarize our findings concisely and contextualize this data with their own findings. The main goal of our paper was to quantify the differences between synovial and infrapatellar fat pad (IPFP) AT deposits from the same patient. The synovial AT had more pro-inflammatory/pro-fibrotic response than the IPFP in patients with obesity...

Brown adipose tissue is a key metabolic organ that oxidizes fatty acids and glucose to generate heat. Through epigenomic analyses of multiple adipose depots, the transcription factor nuclear factor I-A (NFIA) is now shown to drive the brown fat genetic program through binding to lineage-specific cis-regulatory elements.

BACKGROUND/OBJECTIVES: Mutations in the Tubby gene (TUB) cause late-onset obesity and insulin resistance in mice and syndromic obesity in humans. Although TUB gene function has not yet been fully elucidated, studies in rodents indicate that TUB is involved in the hypothalamic pathways regulating food intake and adiposity. Aside from the function in central nervous system, TUB has also been implicated in energy metabolism in adipose tissue in rodents. We aimed to determine the expression and distribution patterns of TUB in man as well as its potential association with obesity...

BACKGROUND: Adipose fat transfer is increasingly used for contour corrections of the tumor bed after lumpectomy and breast reconstructions after mastectomy. The lipophilic nature of the fat tissue may render adipocytes an ideal vehicle with which to deliver a high boost of an antiestrogen to the tumor bed to serve as an adjunct systemic hormonal therapy. The authors therefore tested whether adipocytes could safely be loaded with an antiestrogen and allow for release at therapeutic concentrations to treat breast cancer...

A correlation exists between the extent of pericardial adipose and atrial fibrillation (AF) risk, though the underlying mechanisms remain unclear. Selected adipose depots express high levels of aromatase, capable of converting androgens to estrogens - no studies have investigated aromatase occurrence/expression regulation in pericardial adipose. The Women's Health Initiative reported that estrogen-only therapy in women elevated AF incidence, indicating augmented estrogenic influence may exacerbate cardiac vulnerability...

BACKGROUND: Obesity is associated with the development and progression of osteoarthritis (OA). Although the infrapatellar fat pad (IFP) could be involved in this association, due to its intracapsular localization in the knee joint, there is currently little known about the effect of obesity on the IFP. Therefore, we investigated cellular and molecular body mass index (BMI)-related features in the IFP of OA patients. METHODS: Patients with knee OA (N = 155, 68% women, mean age 65 years, mean (SD) BMI 29...

PURPOSE OF REVIEW: The review aims to summarize the literature describing the clinical impact of cardiac fat depots in patients with HIV infection. RECENT FINDINGS: People living with HIV (PLHIV) have accelerated rates of cardiovascular disease, and are prone to the development of ectopic fat deposition. Specifically, PLHIV have higher volumes of epicardial and intracardiac fat quantified by noninvasive imaging. Higher volumes of epicardial fat may be related to antiretroviral therapy duration and chronic inflammation, independently of other measures of body adiposity such as BMI...

Bone marrow fat is a unique fat depot that may regulate bone metabolism. Marrow fat is increased in states of low bone mass, severe underweight, and diabetes. However, longitudinal effects of weight loss and improved glucose homeostasis on marrow fat are unclear, as is the relationship between marrow fat and bone mineral density (BMD) changes. We hypothesized that after Roux-en-Y gastric bypass (RYGB) surgery, marrow fat changes are associated with BMD loss. We enrolled 30 obese women, stratified by diabetes status...
