Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects joints, connective tissues and the axial skeleton. Metabolic syndrome is an independent risk factor for psoriasis (Pso) development and is associated with more severe forms of Pso. Adipocytokines are secreted by white adipose tissue and are thought to link obesity with the development of metabolic and cardiovascular diseases. Secukinumab is a new monoclonal antibody with a different mechanism of action. This antibody selectively binds to and neutralizes interleukin-17 (IL-17) and it has shown efficacy in the treatment of PsA...

Migration of fibroblast-like preadipocytes is important for the development of adipose tissue, whereas excessive migration is often responsible for impaired adipose tissue related with obesity and fibrotic diseases. Type I collagen (collagen I) is the most abundant component of extracellular matrix and has been shown to regulate fibroblast migration in vitro, but its role in adipose tissue is not known. Silibinin is a bioactive natural flavonoid with antioxidant and antimetastasis activities. In this study, we found that type I collagen coating promoted the proliferation and migration of murine 3T3-L1 preadipocytes in a dose-dependent manner, implying that collagen I could be an extracellular signal...

BACKGROUND: Schizophrenia is a psychiatric disorder with a higher mortality than that of the general population. Most of the deaths are due to cardiovascular causes and are related to metabolic risks. This risk is due not only to antipsychotics but also to inherent factors of the disorder. Studies in the West have shown topiramate to be effective in schizophrenia to reduce weight gain and for symptomatic control. Whether this is effective for South Asians is not known. It is important because South Asians have a higher risk of metabolic syndrome...

Berberine, an important natural isoquinoline alkaloid from traditional Chinese medicine, is reported to exhibit multiple pharmacological properties, including anti-microbial, anti-diabetes, anti-obesity, anti-inflammatory and anti-carcinogenic activities. Although studies have shown that a wide range of carcinoma cells could be inhibited by berberine, few studies involved thyroid carcinoma. We therefore examined the effect of berberine on papillary thyroid carcinoma (PTC, the most common subtype) and anaplastic thyroid carcinoma (ATC, the most malignant and aggressive subtype)...

Aldosterone plays a pivotal role in the pathogenesis of metabolic syndrome and cardiovascular disease; however, the underlying mechanisms have not been clarified. Chemerin has been characterized as an adipokine with crucial roles in obesity-associated disorders and cardiovascular homeostasis. The aim of the present study was to investigate the direct effects of aldosterone on chemerin expression and secretion in 3T3-L1 adipocytes and to identify the potential signalling pathways involved. Chemerin mRNA levels were measured using real-time PCR, whereas the levels of secreted chemerin in the culture media were determined using ELISA...

Recent research indicates that the hypothalamic neuropeptide hormone oxytocin is a key central nervous system factor in the regulation of food intake and weight. However, the mechanisms underlying the anorexigenic effects of oxytocin in humans are unknown and critical to study in order to consider oxytocin as a neurohormonal weight loss treatment. We performed a randomized, double-blind, placebo-controlled crossover study with single-dose intranasal oxytocin (24 IU) in ten overweight or obese, otherwise healthy men...

Stimulation of the ubiquitin-proteasome pathway-especially E3 ubiquitin ligases Atrogin-1 and MuRF1-is associated with muscle loss in diabetes. Elevated lipid metabolites impair myogenesis. Oligonol, a low molecular weight polyphenol derived from lychee, exhibited anti-diabetic and anti-obesity properties, suggesting it could be a proper supplement for attenuating muscle loss. Dietary (10 weeks) oligonol supplementation (20 or 200 mg/kg diet) on the skeletal muscle loss was investigated in diabetic db/db mice...

Obesity is a risk factor for developing severe disease following influenza virus infection; however, the comorbidity of obesity and secondary bacterial infection, a serious complication of influenza virus infections, is unknown. To fill this gap in knowledge, lean and obese C57BL/6 mice were infected with a nonlethal dose of influenza virus followed by a nonlethal dose of Streptococcus pneumoniae Strikingly, not only did significantly enhanced death occur in obese coinfected mice compared to lean controls, but also high mortality was seen irrespective of influenza virus strain, bacterial strain, or timing of coinfection...

Components of the metabolic syndrome (MetS), including abdominal obesity, low-grade chronic systemic inflammation, altered glucose metabolism, dyslipidemia and high blood pressure, are major threats to healthy aging in modern societies. The connection between MetS components and gut microflora is now acknowledged and multiple therapeutic strategies have been proposed to change the composition of the gut microbiota in order to promote optimal metabolic health. Prebiotics have the ability to favour growth of beneficial bacteria, especially short-chain fatty-acids (SCFA) producers...

BACKGROUND: With the advent of effective antivirals against cytomegalovirus (CMV), use of CMV hyperimmune globulin has decreased. Although antiviral prophylaxis in patients at high risk for CMV is effective, many patients still have late infection, never developing antibodies sufficient to achieve immunity. Utilizing a combination of antiviral and CMV immunoglobulin G may allow patients to achieve immunity and decrease late CMV infections. METHODS: This was a prospective randomized, open-label, pilot study comparing valganciclovir (VGCV) prophylaxis for 200 days vs VGCV for 100 days followed by CMV HIG in abdominal transplant recipients at high risk for CMV...

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...

Saringosterol, a steroid isolated from Sargassum muticum, a brown edible alga widely distributed on the seashores of southern and eastern Korea, has been shown to exhibit anti-obesity effect. In this study, we investigated the anti-obesity activity of saringosterol through various experiments. The inhibitory effect of saringosterol on adipogenesis was evaluated via Oil Red O staining in 3T3-L1 preadipocytes. After confirming that saringosterol is not cytotoxic to these cells by using the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay, the effect of saringosterol on the expression of various adipogenesis-related genes was analyzed via quantitative real-time polymerase chain reaction and western blotting...

Generally, licensed drug-dosing recommendations for chemotherapy are based on results from clinical trials in which subjects are usually of relatively normal body size, middle-aged, and are relatively racially homogeneous, with minimal comorbidity and specific tumor characteristics. Very few nontrial patients meet these characteristics, resulting in clinical practice having to extrapolate dosing recommendations to the specific patient. There is insufficient research on the impact of obesity-associated physiological changes prevalent in patients with common cancers on standard pharmacokinetic and pharmacodynamic parameters...

OBJECTIVE: Enhanced activation of cell specific mineralocorticoid receptors (MRs) in obesity plays a key role in the development of cardiovascular disease including cardiac diastolic dysfunction as a critical prognosticator. Our previous investigations demonstrated that selective endothelium MR activation promotes a maladaptive inflammatory response and fibrosis in cardiovascular tissue in female mice fed a western diet (WD), and this was associated with expression and activation of the epithelial sodium channel on the surface of endothelial cells (EnNaC)...

Continuous administration of a 14-amino acid peptide YY (PYY) analog, Ac-[d-Pro(24),Pya(4)(26),Cha(27,36),Aib(28,31),Lys(30)]PYY(23-36) (4), which has a high binding affinity and agonist activity for the neuropeptide Y2 receptor (Y2R), has previously shown an antiobesity effect in a 2-week diet-induced obesity (DIO) study in mice. However, there remained a possibility to obtain more potent analogs by further improving its pharmacokinetic profile. A combination of the N-terminal 4-imidazolecarbonyl moiety and three amino acid substitutions, trans-4-hydroxy-d-proline (d-Hyp)(24), isovaline (Iva)(25), and γ-methylleucine (γMeLeu)(28), not only improved the binding affinity of the peptide for Y2R but also increased its anorectic activity in lean mice...

Soy may be a suitable food for anti-obesity efforts because of its high protein and isoflavone content. We conducted this meta-analysis to evaluate potential effects of soy and soy isoflavones on weight, waist circumference, and fat mass. PubMed, MEDLINE, Scopus, EMBASE, and Cochrane databases were searched. Twenty-four trials with soy and 17 trials with isoflavones passed the eligibility stage. According to the results, soy showed no overall statistically significant effect on weight, waist circumference, or fat mass, but a significant increasing effect on weight was observed in some circumstances: for instance, in obese subjects [mean difference (MD): 0...

PURPOSE OF REVIEW: Vitamin D is essential for bone health, and may also have important functions in immunity and other systems. Vitamin D deficiency is common, and testing and supplementation is increasing. Serum vitamin D is lower in obese people; it is important to understand the mechanism of this effect and whether it indicates clinically significant deficiency. RECENT FINDINGS: Vitamin D is fat soluble, and distributed into fat, muscle, liver, and serum. All of these compartments are increased in volume in obesity, so the lower vitamin D likely reflects a volumetric dilution effect and whole body stores of vitamin D may be adequate...
