The spectrum of serological markers associated with inflammatory bowel disease (IBD) is rapidly growing. Due to frequently delayed or missed diagnoses, the application of non-invasive diagnostic tests for IBD, as well as differentiation between ulcerative colitis (UC) and Crohn’s disease (CD), would be useful in the pediatric population. In addition, the combination of pancreatic autoantibodies and antibodies against saccharomyces cerevisiae antibodies/perinuclear cytoplasmic antibody (pANCA) improved the sensitivity of serological markers in pediatric patients with CD and UC. some studies suggested that age-associated differences in the patterns of antibodies may be present, particularly in the youngest children. In CD, most patients develop stricturing or perforating complications, and a significant number of patients undergo surgery during the disease course. Based on recent knowledge, serum antibodies are qualitatively and quantitatively associated with complicated CD behavior and CD-related surgery. Pediatric UC is characterized by extensive colitis and a high rate of colectomy. In patients with UC, high levels of anti-CBir1 and pANCA are associated with the development of pouchitis after ileal pouch-anal anastomosis. Thus, serologic markers for IBD can be applied to stratify IBD patients into more homogeneous subgroups with respect to disease progression. In conclusion, identification of patients at an increased risk of rapid disease progression is of great interest, as the application of early and more aggressive pharmaceutical intervention could have the potential to alter the natural history of IBD, and reduce complications and hospitalizations.

Though the pathophysiology of clinical obesity is un-doubtedly multifaceted, several lines of clinical evidence implicate an important functional role for glucagon-like peptide 1(GLP-1) signalling. Clinical studies assessing GLP-1 responses in normal weight and obese subjects suggest that weight gain may induce functional deficits in GLP-1 signalling that facilitates maintenance of the obesity phenotype. In addition, genetic studies implicate a possible role for altered GLP-1 signalling as a risk factor towards the development of obesity. As reductions in functional GLP-1 signalling seem to play a role in clinical obesity, the pharmacological replenishment seems a promising target for the medical management of obesity in clinical practice. GLP-1 analogue liraglutide at a high dose(3 mg/d) has shown promising results in achieving and maintaining greater weight loss in obese individuals compared to placebo control, and currently licensed antiobesity medications. Generally well tolerated, provided that longer-term data in clinical practice supports the currently available evidence of superior short- and longterm weight loss efficacy, GLP-1 analogues provide promise towards achieving the successful, sustainable medical management of obesity that remains as yet, an unmet clinical need.

AIm To analyze access(availability, affordability and acceptability) to biologicals for Crohn's disease(CD) in ten European countries and to explore the associations between these dimensions, the uptake of biologicals and economic *** A questionnaire-based survey combined with desk research was carried out in may 2016. Gastroenterologists from the Czech Republic, France, Germany, Hungary, Latvia, Poland, Romania, slovakia, spain and sweden were invited to participate and provide data on the availability of biologicals/biosimilars, reimbursement criteria, clinical practice and prices, and use of biologicals. An availability score was developed to evaluate the restrictiveness of eligibility and administrative criteria applied in the countries. Affordability was defined as the annual cost of treatment as a share of gross domestic product(GDP) per capita. Correlations with the uptake of biologicals, dimensions of access and GDP per capita were *** At the time of the survey, infliximab and adalimumab were reimbursed in all ten countries, and vedolizumab was reimbursed in five countries(France, Germany, Latvia, slovakia, sweden). Reimbursement criteria were the least strict in sweden and Germany, and the strictest in Hungary, Poland and slovakia. Between countries, the annual cost of different biological treatments differed 1.6-3.3-fold. Treatments were the most affordable in sweden(13%-37% of the GDP per capita) and the least affordable in the Central and Eastern European countries, especially in Hungary(87%-124%) and Romania(141%-277%). Biosimilars made treatments more affordable by driving down the annual costs. The number of patients with CD on biologicals per 100000 population was strongly correlated with GDP per capita(0.91), although substantial differences were found in the uptake among countries with similar economic development.

The Al tolerance of newly developed wheat/barley disomic addition, substitution and translocation lines carry chromosomes of three different barley cultivars was evaluated by comparing the root growth in solution containing 75 μm AlCl3 at pH 4.0 to that of known Al-tolerant and sensitive wheat genotypes. The wheat Asakaze komugi, barley manas cultivars and their hybrid derivatives were found to have high levels of Al tolerance. The wheat line mv9kr1, barley cultivar Igri and progenies of the hybrids were sensitive to Al. In most cases, the Al tolerance of the wheat/barley introgression lines derived from Al-sensitive wheat mv9kr1 and barley Betzes with moderate Al tolerance was similar to that of the wheat parents, but the 2Ds.2DL-1Hs translocation line of mv9kr1/Betzes exhibited more intensive root growth, while accumulating less Al than the parental lines. This indicates that either the lack of the distal part of chromosome 2DL or the presence of the distal part of 1Hs improved the Al tolerance level.

many environmental chemicals and pesticides have been found to alter neuroendocrine communication in exposed biological objects. The environmental loads have primary and secondary effects that can alter the homeostatic regulation potential. since it is difficult to avoid human exposition, a potentially important area of research to develop in vivo and in vitro experimental models. In this context, the primary aim of this study was to demonstrate the effects of chlorobenzenes on adrenocorticotrophic hormone（ACTH） release. In our experimental study, male Wistar rats were exposed to 0.1, 1.0 and 10 μg/b.w.（body weight） kg of 1,2,4-trichlorobenzene and hexachlorobenzene（Cl B） mix via gastric tube for 30, 60 or 90 days. At the endpoints of the experiment blood samples were taken and animals were decapitated. Primary,monolayer adenohypophysis cell cultures were prepared by enzymatic and mechanical digestion. The ACTH hormone content in serum and supernatant media was measured by immuno-chemiluminescence assay. The mg2＋-dependent ATPase activity was determined by modified method of martin and Dotty. significant differences were detected in the hormone release between the control and treated groups. The hormone release was enhanced characteristically in exposed groups depending upon the dose and duration of exposure. The mg2＋-ATPase activity enhanced after chronic and subtoxic Cl B exposition. Light microscopy revealed that the adenohypophysis seemed to be more abundant. Results indicate that Wistar rats exposed to subtoxic Cl B have direct and indirect effects on hypothalamus–hypophysis–adrenal axis.
