In this report we analyzed the expression and distribution of leptin and ghrelin in the digestive apparatus of DIO zebrafish. Leptin is anorexigenic peptide while ghrelin is orexigenic one. They act as antagonists. In this study in order to develop an obesity phenotype adult zebrafish were divided into two dietary groups. The con-trol group was fed with Artemia (5 mg cysts/fish/day) once per day. The overfeeding group was fed three times per day with Artemia (60 mg cysts/fish/day). For calorie restriction, the zebrafish was fed with Artemia (2.5 mg cysts/fish/day) for 2 weeks after being overfed for 8 weeks. At the end of this period, after 24h of fasting, the zebrafish digestive apparatus were sampled for immunohistochemistry, western blotting and qRT-PCR techniques. Leptin and ghrelin immunoreactivity were found in the enteric nervous system and neuroen-docrine cells in overfeeding and control zebrafish intestine. The number of immunopositive cells is greater in DIO zebrafish than in control ones. In both groups leptin immunoreactive nervous fibers were found around ducts and vessels of liver. The presence of proteins were confirmed by western blotting analysis. By qRT-PCR, leptin and ghrelin mRNA levels are higher in the overfeeding zebrafish intestine and in control zebrafish liver. The immunological detection of ghrelin and leptin in control zebrafish are in agreement with literature data. In DIO zebrafish the results are similar to those found for obese mammals. In conclusion, this study represent a starting point to investigate the mechanisms involved in the regulation of appetite and energy balance in DIO zebrafish

Thrombin generation in children with acute lymphoblastic leukemia: effect of leukemia immunophenotypic subgroups
Elevated plasma concentrations of endogenous thrombin generation markers and thrombotic events have been reported in children with leukemia. The aim of this study was to evaluate the effects of cancer and its treatment on thrombin generation (TAT levels) in children with acute lymphoblastic leukemia (ALL). The authors evaluated 32 children (23 M, 9 F) aged between 1 and 15 years (mean 6) affected by ALL (immunophenotypic subgroups: 16 common, 7 T, and 9 pre-B type). In all patients TAT levels at onset and after 5-6 doses of L-asparaginase were evaluated. TAT levels were higher in patients both at onset (13.04 ± 10.90 ng/L) and after the 5-6 doses of L-asp (19.41 ± 11.05 ng/L) with respect to controls (4 ± 1 ng/L) (p < .001 and p < .001). TAT levels after 5-6 doses of L-asp were higher than those at onset (p < .001). Factorial ANOVA showed that at onset there was a significant effect of leukemia immunophenotypic subgroups upon TAT levels (p < .05) and no effect of inherited thrombotic risk factors. These results indicate that in children with ALL an important role is played by acquired thrombotic risk factors, among which the indirect cancer procoagulant activity has its importance

Nicotinic acetylcholine receptors in rat forebrain that bind ¹⁸F-nifene: relating PET imaging, autoradiography, and behavior
Nicotinic acetylcholine receptors (nAChRs) in the brain are important for cognitive function; however, their specific role in relevant brain regions remains unclear. In this study, we used the novel compound ¹⁸F-nifene to examine the distribution of nAChRs in the rat forebrain, and for individual animals related the results to behavioral performance on an auditory-cognitive task. We first show negligible binding of ¹⁸F-nifene in mice lacking the β2 nAChR subunit, consistent with previous findings that ¹⁸F-nifene binds to α4β2* nAChRs. We then examined the distribution of ¹⁸F-nifene in rat using three methods: in vivo PET, ex vivo PET and autoradiography. Generally, ¹⁸F-nifene labeled forebrain regions known to contain nAChRs, and the three methods produced similar relative binding among regions. Importantly, ¹⁸F-nifene also labeled some white matter (myelinated axon) tracts, most prominently in the temporal subcortical region that contains the auditory thalamocortical pathway. Finally, we related ¹⁸F-nifene binding in several forebrain regions to each animal's performance on an auditory-cued, active avoidance task. The strongest correlations with performance after 14 days training were found for ¹⁸F-nifene binding in the temporal subcortical white matter, subiculum, and medial frontal cortex (correlation coefficients, r > 0.8); there was no correlation with binding in the auditory thalamus or auditory cortex. These findings suggest that individual performance is linked to nicotinic functions in specific brain regions, and further support a role for nAChRs in sensory-cognitive function.Peer reviewedAuthor's Manuscript is also available open access in PubMed Central: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3292694.This is the peer reviewed version of the following article: Bieszczad, K.
