Hepatitis C virus (HCV) infection remains the main cause of liver disease and can lead to chronic hepatitis, cirrhosis, and hepatocellular carcinoma. HCV may also develop extrahepatic manifestations in the skin, eyes, joints, kidneys, nervous system, and immune system. In fact, several studies reported that up to 70% of HCV patients experienced extrahepatic manifestations. Lichen planus (LP), which is an immune system disorder that is triggered by viral infections, allergens, and stress, can affect the skin, mouth, nails, and scalp...

A pandemic of metabolic diseases, consisting of type-2 diabetes, non-alcoholic fatty liver diseases (NAFLD) and obesity, has imposed critical challenges for societies worldwide, prompting investigation of underlying mechanisms and exploration of low cost and effective treatment. In this report, we demonstrate that metabolic disorders in mice generated by feeding with a high-fat diet without dietary vitamin D (HD) can be prevented by oral administration of polycationic amine resin. Oral administration of cholestyramine , but not the control uncharged polystyrene, was able to sequester negatively charged bacterial endotoxin in the gut, leading to (1) reducing plasma endotoxin levels, (2) resolving systemic inflammation and hepatic steatohepatitis,and (3) improving insulin sensitivity...

The prevalence of non-alcoholic fatty liver disease is increasing rapidly worldwide. However, effective strategies for combating high-fat diet (HFD) induced obesity, fatty liver and metabolic disorder are still limited, and outcomes remain poor. In the present study, we evaluated the combined actions of dietary capsaicin and antibiotics on HFD-induced physiological abnormalities in mice. C57BL/6 male mice were fed with HFD (60% calories from fat) for 17 weeks, and the resultant pathophysiological effects were examined...

REVIEW
Jeongho Kim, Young-Jai You
Metformin ameliorates hyperglycemia without the side effects of lactic acidosis or hypoglycemia. Metformin lowers the blood glucose level by decreasing hepatic glucose production in the liver and by increasing glucose uptake in the muscle. Recent studies show that metformin induces cell death in certain cancer cell lines by interfering with the metabolism of the cancer cells. Therefore, understanding the mechanisms of action for metformin will provide insights into how to better treat diabetes and other metabolic disorders and also into the development of new therapeutic drugs...

3,4-Methylenedioxymethamphetamine (MDMA; ecstasy) is being investigated in MDMA-assisted psychotherapy. The present study characterized the safety pharmacology of single-dose administrations of MDMA (75 or 125 mg) using data from nine double-blind, placebo-controlled, crossover studies performed in the same laboratory in a total of 166 healthy subjects. The duration of the subjective effects was 4.2 ± 1.3 h (range: 1.4-8.2 h). The 125 mg dose of MDMA produced greater 'good drug effect' ratings than 75 mg. MDMA produced moderate and transient 'bad drug effect' ratings, which were greater in women than in men...

Major depressive disorder (MDD) has a complex etiology and is characterized by a change in mood and psychophysiological state. MDD has been shown to mediate accelerated biological aging in patients, although the underlying mechanism is not well understood. In the present study, we used a chronic mild stress (CMS) paradigm to induce anhedonia, one of the main symptoms of MDD. CMS induced depression-like symptoms in rats, including reduced sucrose preference and increased immobility time in the forced swim test...

Obesity remains the most prevailing disorder in childhood males and females worldwide. Its high prevalence markedly predisposes children to insulin resistance, hypertension, hyperlipidemia and liver disorders while enhancing the risk of type 2 diabetes and cardiovascular diseases. In this review, the relationship of obesity with genetic and environmental factors will be described and the underlined causes will briefly be reported. As obesity in children constitutes an increasingly health concern, important potential biomarkers have been discussed for the diagnosis, treatment and follow-up of the wide range of overweight-related complications...

Androgen as well as estrogen has physical, psychological and sexual roles in women. The action of androgen on bone health in women is important. The androgen receptor is expressed in osteoblasts and osteocytes but the mechanism has not been clarified in women. It has been reported that endogenous testosterone level was positively correlated with bone mineral density and higher testosterone level might be associated with decrease in bone fractures. Also, it has been reported that bone mineral density in women who received testosterone with estrogen was higher than that in women who received estrogen alone...

The angiotensin (Ang) converting enzyme 2/Ang-(1-7)/Mas axis has been described to have a beneficial role on metabolic disorders. In the present study, the use of a transgenic rat model that chronically overexpresses Ang-(1-7) enabled us to investigate the chronic effects of this peptide on lipid accumulation in the liver and adipose tissue. The transgenic group showed a marked tendency toward increased expression of peroxisome proliferator-activated receptor-γ (PPARγ) and decreased lipoprotein lipase (LPL) expression and activity in epididymal adipose tissue...

Reported hepatotoxicity induced by corticosteroids is very rare, and the diagnosis is highly challenging in the context of auto-immune disease. We report here a case of high-dose methylprednisolone (MP)-induced acute hepatitis confirmed by liver histology in a patient with multiple sclerosis (MS) and a case series (n=4) notified to the French Pharmacovigilance center of Lyon. In all 5 cases, other common causes of hepatitis were excluded. The causal relationship with MP pulse therapy was supported by the fact that MP was the only culprit drug...

Lipotoxicity induced by saturated fatty acids (SFAs) plays a central role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD); however, the exact mechanism(s) remain to be fully elucidated. SIRT3 is an NAD(+) -dependent deacetylase primarily located inside mitochondria. In this study, we demonstrated that a SFAs-rich high-fat diet (HFD) was more detrimental to the liver than an isocaloric unsaturated FAs-rich HFD. Unexpectedly, SIRT3 expression/activity were significantly elevated in the livers of mice exposed to the SFAs-rich HFD...

The profile of bile acids (BA) largely depends on the enzymatic activity of the microbiota, but this can be modulated by the dietary addition of biologically active compounds, e.g., polyphenols and polyunsaturated fatty acids. The aim of this study was to examine the effect of dietary raspberry pomace as a rich source of biologically active compounds on microbial activity and the BA profile in the caecum of rats fed a high-fat diet. Wistar rats were fed the standard diet AIN-93, a high-fat diet or a modified high-fat diet enriched with 7% different types of processed raspberry pomaces produced by standard grinding and fine grinding, with or without seeds...

Crotadihydrofuran C (CC) from the herbs of Crotalaria albida is able to inhibit adipocyte differentiation and lipid accumulation. However, the effects of CC on obesity and metabolic disorders have not yet been elucidated. In our study, the first enantioselective synthesis of the 2-isopropenyl dihydrofuran isoflavone skeleton (CC) is described. The convenient and efficient synthetic protocols developed skilfully solve the problems of the ortho-para directing group and Suzuki coupling reaction using a boronic acid pinacol ester that was more stable and easy to obtain...
