ABSTRACT Introduction Chronic nausea and vomiting are symptoms of a wide range gastrointestinal non‐gastrointestinal conditions. Diagnosis can be challenging requires systematic well‐structured approach. If the initial investigation for structural, toxic metabolic disorders is negative, digestive motility gut‐brain interaction should assessed.

Introduction . Chemerin seems to be involved in pathogenesis of chronic hepatitis C (CHC). Hepatic expressions chemerin and its receptor, chemokine receptor-like 1 (CMKLR1), CHC have not been studied so far. Aim To evaluate CMKLR1 hepatic expression together with serum concentration patients assess their relationship metabolic histopathological abnormalities. Methods The study included 63 nonobese patients. Transcription was assessed by quantitative real-time PCR, while enzyme-linked...

Chronic hepatitis C (CHC) is accompanied by numerous metabolic disorders, partially associated with altered adipokine system regulation. Omentin (intelectin-1) a novel known to play pivotal role in regulation CHC. In group of 63 CHC patients (29 men/34 women) infected genotype 1b, aged 6.6 ± 14.6 years, serum omentin levels and its gene expression liver tissue were examined their association histopathological features was assessed.

Low caloric diet is a commonly accepted treatment in obesity. However, owing to moderate results, pharmacological support has been proposed. As some efficacious drugs activate overall sympathetic activity, they might modify functions of the cardiovascular system. Three groups subjects were studied: (1) nine obese women receiving only standard hypocaloric diet; (2) and ephedrine (2 × 25 mg) with caffeine 200 mg); (3) yohimbine 5 mg). The state was evaluated by thoracic electrical...
