Curcumin improved survival and minimized oxidative stress, hepatocellular injury and hepatic necroinflammation, NFkappaB binding and iNOS expression in a rat model of FHF. These findings support the role of ROS, NFkappaB and iNOS in mediating liver insult due to TAA, and that of curcumin as a hepato-protectant.
Autonomic dysfunction in Parkinson's disease (PD) is considered a late complication of the disease or an adverse effect of anti-parkinsonian medications. Morphological changes are demonstrated only by postmortem examination. The study objective was to evaluate peripheral autonomic neural involvement in PD using punch skin biopsy. The study sample included 22 patients (mean age 50 +/- 7.7 years, mean disease duration 5.3 +/- 3.8 years) and 19 controls. Four-millimeter skin biopsies were immunohistochemically stained with anti-PGP 9.5 antibody. Autonomic innervation of the blood vessels, sweat glands, and erector pili muscles was assessed and rated from 0 (normal) to 2 (severe). Cutaneous autonomic innervation was decreased in patients compared to controls. Semi quantitative analysis demonstrated reduced autonomic innervation of the blood vessels (1.0 +/- 0.8 vs. 0.42 +/- 0.8 in controls; p < 0.02), of sweat glands (0.95 +/- 0.67 vs. 0.47 +/- 0.61; p < 0.02) and of the erector pili muscles (1.06 +/- 0.55 vs 0.21 +/- 0.42; p < 0.001). This method demonstrates that the peripheral autonomic system is affected in PD at early stage of the disease and that autonomic involvement in PD may be more prevalent than previously thought.
Aim:
To evaluate the sensitivity and specificity of a new 13C urea breath test, Oridion BreathID, for the diagnosis of Helicobacter pylori.
Methods:
A total of 97 consecutive symptomatic patients referred for upper endoscopy were included in the ‘pre‐therapy’ part of the study. After endoscopy the patients were analysed for H. pylori by Oridion BreathID. BreathID continuously sampled the subject’s breath for 20 min, and displayed the results on the BreathID screen in real time. Results of the BreathID were compared with the ‘gold standard’ (rapid urease test and histology). We also prospectively tested the validity of BreathID in comparison to isotope ratio mass spectrometry, in 40 patients referred to monitor the efficacy of H. pylori eradication treatment.
Results:
Complete agreement was observed between the ‘gold standard’ and the Breath ID test in 96.9% (94 out of 97) of the patients. The sensitivity and specificity of BreathID were 97.8% and 96.1%, respectively. The correlation between BreathID and isotope ratio mass spectrometry breath test was 100%.
Conclusions:
The Oridion BreathID has comparable sensitivity and specificity to the claims of the currently available urea breath tests. Furthermore, BreathID has the potential advantages of ease of use with minimal medical staff requirement, and real time rapid results (20 min maximum) which may make the BreathID preferable to other urea breath test assays.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
