Osteoarthritis is a common chronic joint disorder affecting older people. The knee is the major joint affected. The symptoms of osteoarthritis include limited range of motion, joint swelling, and pain causing disability. There are no disease modifying drugs available, and treatments are mainly focused on pain management. Total knee replacement performed at the end stage of the disease is considered the only cure available. It has been found that obese people have an increased risk to develop not only knee but also hand osteoarthritis...

OBJECTIVES: Food insecurity, defined as the limited or uncertain availability of nutritious and safe foods, is a complex phenomenon and is linked to poor nutrition and diet-sensitive chronic diseases. Dietary patterns that include saturated fats and meat products are potential risk factors for the progression of peripheral arterial disease (PAD). This study explored whether there is a relationship between food insecurity and PAD among a national sample of older adults. DESIGN: We conducted a cross-sectional data analysis using data from the 1999-2004 National Health and Nutrition Examination Survey (NHANES)...

Estrogen, via estrogen receptor alpha (ERα), exerts several beneficial effects on metabolism and energy homeostasis by controlling size, enzymatic activity and hormonal content of adipose tissue. The actions of estrogen on sympathetic ganglia, which are key players in the browning process, are less well known. In the present study we show that ERβ influences browning of subcutaneous adipose tissue (SAT) via its actions both on sympathetic ganglia and on the SAT itself. A 3-day-treatment with a selective ERβ agonist, LY3201, induced browning of SAT in 1-year-old obese WT and ERα(-/-) female mice...

Pioglitazone is a peroxisome proliferator-activated receptor gamma (PPARγ) full agonist and useful for the treatment of type 2 diabetes mellitus. Naringenin is a citrus flavonoid with anti-inflammatory actions, which has been shown to prevent obesity-related diseases and to activate PPARγ. The aim of this study was to investigate whether dietary naringenin affects the actions of pioglitazone. We administered naringenin (100 mg/kg) and pioglitazone (10 mg/kg) to Tsumura Suzuki Obese Diabetes (TSOD) mice for 4 weeks and then conducted an oral glucose tolerance test...

OBJECTIVES: Based on a novel approach suggesting a role of adipose tissue in osteoarthritis (OA), we aimed to determine whether the infrapatellar fat pad (IFP) may affect joint cell functions through adipokines. METHODS: The conditioned media of IFP and subcutaneous adipose tissue from OA patients were used to determine the production of leptin and adiponectin, and to stimulate chondrocytes and fibroblast-like synoviocytes (FLS). Blocking experiments were carried out to evaluate the contribution of adipokines to IFP effects...

PURPOSE: Knee joint is one of the largest and most complex joints of the body. Knee joint diseases are common, and current clinical imaging technologies such as x-ray computed tomography, magnetic resonance imaging, and ultrasound imaging have limitations in the diagnosis of knee joint diseases. Emerging imaging technologies such as diffuse optical tomography and photoacoustic imaging (PAI) have been applied to the detection of osteoarthritis (OA). However, they are limited to small joints such as the finger and difficult to be used for large joints such as the knee...

BACKGROUND: The gastrointestinal tract is populated by a complex and vast microbial network, with a composition that reflects the relationships of the symbiosis, co-metabolism, and co-evolution of these microorganisms with their host. The mechanism that underlies such interactions between the genetics of the host and gut microbiota remains elusive. RESULTS: To understand how genetic variation of the host shapes the gut microbiota and interacts with it to affect the metabolic phenotype of the host, we compared the abundance of microbial taxa and their functional performance between two lines of chickens (fat and lean) that had undergone long-term divergent selection for abdominal fat pad weight, which resulted in a 4...

BACKGROUND: Recent anatomical findings have suggested that facial fat distribution is complex and changes with age. Here, we developed a grafting technique based on the physiological distribution and volume changes of facial fat compartments to achieve a youthful and natural-looking face. METHODS: Forty cadaveric hemifaces were used for the dissection of fat compartments and neurovascular structures in the mid-face area. Seventy-eight patients were treated for cheek atrophy using our targeted restoration of mid-face fat compartment volume...

Signalling through VEGF receptors and the Tie2 receptor by angiopoietins is required in combination with blood flow for the formation of a functional vascular network. We tested the hypothesis that VEGF and Ang1 contribute differentially to neovascularization induced by nitric oxide (NO) mediated vasodilatation, by comparing the phenotype of new microvessels in the mesentery during induction of vascular remodelling by over-expression of endothelial nitric oxide synthase (eNOS) in the fat pad of the adult rat mesentery during inhibition of Angiopoietin signalling with soluble Tie2 and VEGF signalling with sFlt1...

The existence of multipotent adipose-derived stem cells isolated from human orbital fat (OF) tissue has shown great therapeutic potential in tissue engineering and regenerative medicine. But the use of stem cells for therapeutic applications is influenced by their proliferative and differentiation potentials, which may be affected by the age of the donor. So far there is little knowledge about the effects of donor age on the biological properties of human orbital adipose-derived stem cells (OASCs). The intraorbital fat protrusion in the lower eyelids occurs as an aging process, and the protruded fat is routinely removed during aesthetic surgeries...

The distal colon functions as a bioreactor and harbors an enormous amount of bacteria in a mutualistic relationship with the host. The microbiota have to be kept at a safe distance to prevent inflammation, something that is achieved by a dense inner mucus layer that lines the epithelial cells. The large polymeric nets made up by the heavily O-glycosylated MUC2 mucin forms this physical barrier. Proteomic analyses of mucus have identified the lectin-like protein ZG16 (zymogen granulae protein 16) as an abundant mucus component...
