Extensive studies have demonstrated that biochanin A (BCA) has a significant hypolipidemic effect. However, its mechanism of action is not clear. In this context, the effect of BCA on a high-fat diet (HFD)-induced hyperlipidemia in mice was determined. The results showed that treatment with a medium dose of biochanin A (BM) significantly decreased low density lipoprotein cholesterol (LDL-C) 85% (from 1.196 ± 0.183 to 0.181 ± 0.0778 mM) and total cholesterol (TC) 39% (from 5.983 ± 0.128 to 3.649 ± 0.374 mM) levels, increased lipoprotein lipase (LPL) 96% (from 1...

At the annual Iditarod Race, Alaskan Huskies repeatedly run for up to 8 hours at 16 km/h to complete 1600 km. We previously demonstrated high rates of mitochondrial protein synthesis in Alaskan Huskies, which we suspected allowed rapid remodeling of mitochondrial proteins in response to energetic stress. The purpose of this study was to examine mitochondrial respiration in permeabilized skeletal muscle fibers of Alaskan Huskies in the offseason (Non-raced) and following the 1600 km Iditarod Sled Dog Race (Raced)...

The causes of pain symptoms in the temporomandibular joint (TMJ) and masticatory muscle (MM) regions may not be determined by clinical examination alone. In this review, we document that pain symptoms of the TMJ and MM regions in patients with temporomandibular disorders (TMDs) are associated with computed tomography and magnetic resonance (MR) findings of internal derangement, joint effusion, osteoarthritis, and bone marrow edema. However, it is emphasized that these imaging findings must not be regarded as the unique and dominant factors in defining TMJ pain...

BACKGROUND: The aim of breast conserving surgery (BCS) is to excise the cancer with clear margins whilst at the same time leaving a good or excellent cosmetic result. A significant percentage of women, who have large cancers or have limited breast volumes, achieve poor cosmetic outcomes. BCS with immediate volume replacement using lipofilling or autologous fat transfer is a new technique. The aim of this study was to evaluate the cosmetic outcomes of a pilot study of patients having BCS and immediate lipofilling performed in The Edinburgh Breast Unit...

Derived from the eigenvector method (EM), a vectorial eigenvector method (VEM) for the mode calculation of polarization dependent resonator is presented. New transfer matrices of laser resonant cavities with polarization-selective devices are built by using Jones matrix representation. The eigenvectors computed by solving the matrix eigenequation manifest the mode characteristics of resonators, including cylindrical vector (CV) modes. Comparing with EM, the VEM inherits EM's superiorities and extends scalar models to vector models...

Genetics plays a central role in susceptibility to obesity and metabolic diseases. BALB/c mice are known to be resistant to high fat diet (HFD)-induced obesity, however the genetic cause remains unknown. We report that deletion of the innate immunity antibacterial gene Nod2 abolishes this resistance, as Nod2 (-/-) BALB/c mice developed HFD-dependent obesity and hallmark features of metabolic syndrome. Nod2 (-/-) HFD mice developed hyperlipidemia, hyperglycemia, glucose intolerance, increased adiposity, and steatosis, with large lipid droplets in their hepatocytes...

Soft tissue reconstruction to restore volume to damaged or deficient tissue beneath the skin remains a challenging endeavor. Current techniques are centered around autologous fat transfer, or the use of synthetic substitutes, however a great deal of scientific inquiry has been made into both the molecular mechanisms involved in, as well as limitations of, de novo adipogenesis, i.e. the formation of new adipose tissue from precursor cells. To best comprehend these mechanisms, an understanding of defined markers for adipogenic differentiation, as well as knowledge of both commercially available and primary cell lines that enable in vitro and in vivo studies is necessary...

Background: The role of plasma apolipoprotein (apo) C-I in cardiometabolic risk in humans is unclear. However, in vitro studies showed a dual role for apoC-I, both protective and harmful, depending on the carrier lipoprotein.Objective: We tested the hypothesis that triglyceride (TG)-rich lipoprotein (TRL) apoC-I, not total or HDL apoC-I, is associated with delayed postprandial plasma clearance of TRLs, independently of apoC-II, apoC-III, and apoE.Methods: This cross-sectional study examines the plasma clearance of a (13)C-triolein-labeled high-fat meal (68% fat energy) in 20 postmenopausal overweight and obese women [body mass index (in kg/m(2)) ≥27; aged 45-74 y] as the increment change in area under the 6-h postprandial curves (iAUC6h) of TRL parameters...

Gut microbiota dysbiosis has been implicated in a variety of systemic disorders, notably metabolic diseases including obesity and impaired liver function, but the underlying mechanisms are uncertain. To investigate this question, we transferred caecal microbiota from either obese or lean mice to antibiotic-free, conventional wild-type mice. We found that transferring obese-mouse gut microbiota to mice on normal chow (NC) acutely reduces markers of hepatic gluconeogenesis with decreased hepatic PEPCK activity, compared to non-inoculated mice, a phenotypic trait blunted in conventional NOD2 KO mice...

AIM: Obesity is accompanied with systemic inflammation and pre-conditions to severe alterations in liver environment and functions. So far, it remains elusive to which extent obesity modulates immune responses during hepatotropic virus infections as well as in autoimmune hepatitis. In this study we investigated the influence of obesity on the intrahepatic immune response, in particular on the function of CD8 T cells as the crucial players in clearance of virus infected hepatocytes. METHODS: We established high fat induced obesity in transgenic mouse models with hepatocyte specific expression of a model antigen (Ova)...

Fructose is a highly lipogenic sugar that can alter energy metabolism and trigger metabolic disorders. In the current study, microRNAs (miRNAs) altered by a high-fructose diet were comprehensively explored to elucidate their significance in the pathogenesis of chronic metabolic disorders. miRNA expression profiling using small noncoding RNA sequencing revealed that 19 miRNAs were significantly upregulated and 26 were downregulated in the livers of high-fructose-fed mice compared to chow-fed mice. Computational prediction and functional analysis identified 10 miRNAs, miR-19b-3p, miR-101a-3p, miR-30a-5p, miR-223-3p, miR-378a-3p, miR-33-5p, miR-145a-3p, miR-128-3p, miR-125b-5p and miR-582-3p, assembled as a regulatory network to potentially target key genes in lipid and lipoprotein metabolism and insulin signaling at multiple levels...

NLRP3 (Nod-like receptor family pyrin domain containing 3) inflammasome has been reported to contribute to obesity-induced inflammation and insulin resistance. However, there are few drugs targeting NLRP3 inflammasome for the treatment of insulin resistance. In the present study, we showed that berberine (BBR) significantly suppressed saturated fatty acid palmitate (PA)-induced NLRP3 inflammasome activation and interleukin-1β (IL-1β) release in macrophages, which was one of the most important mediators in the insulin sensitivity of adipose tissue...

On the basis of mouse I-A(b)-binding motifs, two sequences of the murine apolipoprotein B-100 (mApoB-100), mApoB-1003501-3515 (designated P3) and mApoB-100978-992 (designated P6), were found to be immunogenic. In this report, we show that P6 is also atherogenic. Immunization of Apoe(-/-) mice fed a high-fat diet (HFD) with P6 resulted in enhanced development of aortic atheroma as compared to control mice immunized with an irrelevant peptide MOG35-55 or with complete Freund's adjuvant alone. Adoptive transfer of lymph node cells from P6-immunized donor mice to recipients fed an HFD caused exacerbated aortic atheromas, correlating P6-primed cells with disease development...

It is well-known that policosanol can improve serum lipid profiles, although the physiological mechanism is still unknown. Here, we investigated functional and structural changes in lipoproteins after consumption of policosanol. To investigate the physiological effect of policosanol, we analyzed serum parameters in young non-smoker (YN; n=7, 24.0±2.4 years), young smoker (YS; n=7, 26.3±1.5 years), and middle-aged subjects (MN; n=11, 52.5±9.8 years) who consumed policosanol daily (10 mg/day) for 8 weeks...
