The metabolic syndrome and diabetic conditions support atherosclerosis, but the exact mechanisms for accelerated atherogenesis remain unclear. Although the proinflammatory role of STAT4 in atherosclerosis and diet-induced insulin resistance (IR) was recently established, the impact of STAT4 on atherogenesis in conditions of IR is not known. In this study, we generated Stat4(-/-)Ldlr(-/-) mice that were fed a diabetogenic diet with added cholesterol (DDC). DDC-fed Stat4(-/-)Ldlr(-/-) mice demonstrated improved glucose tolerance, insulin sensitivity, and a 36% reduction in atherosclerosis compared with Ldlr(-/-) controls...

As extensively used chemicals in a variety of consumer products, perfluoroalkyl substances (PFASs) are ubiquitous and could bring significant risk to human health. However, the effect of PFASs on metabolic syndrome (MetS) is not fully understood. In 2015, a preliminary cross-sectional study was undertaken. A total of 148 male subjects including 81 affected by MetS and 67 non-MetS participants as the reference were recruited from Physical Examination Center affiliated to Capital Medical University, China. Serum levels of perfluorohexane sulfonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA) were significantly higher in the subjects with MetS...

Diet-associated insulin resistance (IR) is intimately correlated to the progression of metabolic syndrome and hippocampal dysfunction. Pioglitazone (PIO), a selective peroxisome proliferator-activated receptor gamma (PPARγ) agonist, has been applied to enhance insulin sensitivity. With limited permeability to blood-brain-barrier, it is unclear that whether oral PIO available to cure both the peripheral IR and the impairment in hippocampus. We evaluated the levels of peripheral and hippocampal IR via the homeostatic model assessment of insulin resistance and hippocampal IRS-1/Akt phosphorylation, respectively, of Wistar Kyoto rats fed with regular chew or high fructose diet (HFD) for 12weeks...

BACKGROUND: As pain is often a comorbid condition, many patients use opioid analgesics in combination with several other drugs. This implies a generally increased risk of drug interactions, which along with inherent pharmacogenetic variability and other factors may cause differences in therapeutic response of opioids. AIM: To provide an overview of interactions and pharmacogenetic variability of relevance for individual differences in effect and tolerability of opioid analgesics, which physicians and other healthcare professionals should be aware of in clinical practice...

OBJECTIVE: Aphasia is a common presentation of ischemic stroke, often diagnosed in the acute setting using tools such as the NIH Stroke Scale (NIHSS). Due to the vascular distribution of the middle cerebral artery, it is often accompanied by other symptoms such as weakness, sensory loss, or visual changes. Isolated aphasia due to ischemia is possible, but language problems mimicking aphasia syndromes can also be seen with other diagnoses such as metabolic abnormalities or dementia. In this study, we determine the incidence of aphasia-only strokes using the NIHSS, and factors associated with a higher likelihood of ischemia...

Movement disorders are a prominent and common feature in many autoantibody-associated neurological diseases, a group of potentially treatable conditions that can mimic infectious, metabolic or neurodegenerative disease. Certain movement disorders are likely to associate with certain autoantibodies; for example, the characteristic dyskinesias, chorea and dystonia associated with NMDAR antibodies, stiff person spectrum disorders with GAD, glycine receptor, amphiphysin or DPPX antibodies, specific paroxysmal dystonias with LGI1 antibodies, and cerebellar ataxia with various anti-neuronal antibodies...

OBJECTIVE: The Williams-Beuren syndrome (WS) is associated with impaired glucose metabolism (IGM) early in adulthood. However, the pathophysiology of IGM remains poorly defined, due to the lack of longitudinal studies investigating the contribution of β-cell dysfunction and impaired insulin sensitivity. This study aimed at assessing incidence of IGM and the underlying mechanisms in WS adults. METHODS: This observational, longitudinal (5-year), cohort study enrolled thirty-one consecutive WS subjects attending a tertiary referral center...

Androgen deprivation therapy continues to be widely used for the treatment of prostate cancer despite the appearance of new-generation androgen-receptor targeting drugs after 2000. Androgen deprivation therapy can alleviate symptoms in patients with metastatic prostate cancer and might have a survival benefit in some patients, but it causes undesirable changes in lipid, glucose, muscle or bone metabolism. These metabolic changes could lead to new onset or worsening of diseases, such as obesity, metabolic syndrome, diabetes mellitus, cardiovascular disease, sarcopenia or fracture...

Significant differences exist between the highly pathogenic (HP) porcine reproductive and respiratory syndrome virus (PRRSV) and its attenuated pathogenic (AP) strain in the ability to infect host cells. The mechanisms by which different virulent strains invade host cells remain relatively unknown. In this study, pulmonary alveolar macrophages (PAMs) were infected with HP-PRRSV (HuN4) and AP-PRRSV (HuN4-F112) for 24 h, then harvested and subjected to label-free quantitative mass spectrometry. A total of 2849 proteins were identified, including 95 that were differentially expressed...

BACKGROUND: The alanine aminotransferase (ALT)/aspartate aminotransferase (AST) ratio is reportedly associated with insulin resistance (IR). However, few studies have explored the relationship between the ALT/AST ratio and IR in the Chinese population. Here, we aimed to explore whether the ALT/AST ratio is associated and, if so, to what extent, with IR in the Chinese population as categorized by waist circumference (WC). METHODS: Our data were obtained from the SPECT-China study, a cross-sectional survey on the prevalence of metabolic diseases and risk factors in East China from 2014 to 2015...

Polycystic ovary syndrome (PCOS) is the most common endocrine and reproductive disorder in premenopausal women, characterized by hyperandrogenemia, metabolic syndrome, and inflammation. Women who had PCOS during their reproductive years remain hyperandrogenemic after menopause. The consequence of chronic hyperandrogenemia with advanced aging has not been studied to our knowledge. We have characterized a model of hyperandrogenemia in female rats and have aged them to 22-25 months to mimic advanced aging in hyperandrogenemic women, and tested the hypothesis that chronic exposure to hyperandrogenemia with aging has a deleterious effect on renal function...

INTRODUCTION: C-reactive protein (CRP) is often elevated in patients living with severe obesity (BMI≥35kg/m(2)). However, there is limited information on how CRP, and other inflammation responsive biomarkers, change in response to weight loss following laparoscopic sleeve gastrectomy (LSG). We studied how CRP, ferritin and albumin change following LSG surgery in relation to obesity, metabolic syndrome (MetS) ATPIII risk components and diabetes mellitus (DM). METHODS: Laboratory parameters (including CRP) were examined in 197 patients prior to LSG, and at 6, 12, 18 and 24months...

Taurine is a conditionally essential amino acid present in the body in free form. Mammalian taurine is synthesized in the pancreas via the cysteine sulfinic acid pathway. Anti-oxidation and anti-inflammation are two main properties through which it exerts its therapeutic effects. Many studies have shown its excellent therapeutic potential against diabetes mellitus and related complications like diabetic neuropathy, retinopathy, nephropathy, hematological dysfunctions, reproductive dysfunctions, liver and pancreas related complications etc...
