AIM:To assesses the safety and efficacy of Aspergillus niger prolyl endoprotease(AN-PEP)to mitigate the im-munogenic effects of gluten in celiac patients.METHODS:Patients with initial diagnosis of celiac disease as confirmed by positive serology with subtotal or total villous atrophy on duodenal biopsies who adhere to a strict gluten-free diet(GFD)resulting in normalised antibodies and mucosal healing classified as Marsh 0 orⅠwere included.In a randomised double-blind placebo-controlled pilot study,patients consumed toast(approximately 7 g/d gluten)with AN-PEP for 2 wk(safety phase).After a 2-wk washout period with adherence of the usual GFD,14 patients were randomised to gluten intake with either AN-PEP or placebo for 2 wk(efficacy phase).Measurements at baseline included complaints,quality-of-life,serum antibodies,immunophenotyping of T-cells and duodenal mucosa immunohistology.Furthermore,serum and quality of life questionnaires were collected during and after the safety,washout and efficacy phase.Duodenal biopsies were collected after the safety phase and after the efficacy phase.A change in histological evaluation according to the modified Marsh classification was the primary endpoint.RESULTS:In total,16 adults were enrolled in the study.No serious adverse events occurred during the trial and no patients withdrew during the trial.The mean score for the gastrointestinal subcategory of the celiac disease quality(CDQ)was relatively high throughout the study,indicating that AN-PEP was well tolerated.In the efficacy phase,the CDQ scores of patients consuming gluten with placebo or gluten with AN-PEP did not significantly deteriorate and moreover no differences between the groups were observed.During the efficacy phase,neither the placebo nor the AN-PEP group developed significant antibody titers.The IgA-EM concentrations remained negative in both groups.Two patients were excluded from entering the efficacy phase as their mucosa showed an increase oftwo Marsh steps after the safety phase,yet with undetectable s 相似文献

Autism spectrum disorder refers to syndromes of varying severity, typified by impaired social interactions, communicative delays and restricted, repetitive behaviours and interests. The prevalence of autism spectrum disorders has been on the rise, while the etiology remains unclear and most likely multifactorial. There have been several reports of a link between autism and chronic gastrointestinal symptoms. Endoscopy trials have demonstrated a higher prevalence of nonspecific colitis, lymphoid hyperplasia and focally enhanced gastritis compared with controls. Postulated mechanisms include aberrant immune responses to some dietary proteins, abnormal intestinal permeability and unfavourable gut microflora. Two autism spectrum disorder patients with chronic intestinal symptoms and abnormal endoscopic findings are described, followed by a review of this controversial topic. 相似文献

Objective
To evaluate the influence of alternative erasing times of DenOptix® (Dentsply/Gendex, Chicargo, IL) digital plates on subjective image quality and the probability of double exposure image not occurring.Methods
Human teeth were X-rayed with phosphor plates using ten different erasing times. Two observers evaluated the images for subjective image quality (sharpness, brightness, contrast, enamel definition, dentin definition and dentin-enamel junction definition) and for the presence or absence of double exposure image. Spearman''s correlation analysis and ANOVA was performed to verify the existence of a linear association between the subjective image quality parameters and the alternative erasing times. A contingency table was constructed to evaluate the agreement among the observers, and a binominal logistic regression was performed to verify the correlation between the erasing time and the probability of double exposure image not occurring.Results
All 6 parameters of image quality were rated high by the examiners for the erasing times between 25 s and 130 s. The same erasing time range, from 25 to 130 s, was considered a safe erasing time interval, with no probability of a double exposure image occurring.Conclusions
The alternative erasing times from 25 s to 130 s showed high image quality and no probability of double image occurrence. Thus, it is possible to reduce the operating time of the DenOptix® digital system without jeopardizing the diagnostic task. 相似文献995.

KAPUR G., WINDSOR P.M. & Mc COWAN C. (2010) European Journal of Cancer Care 19 , 643–647 The effect of aerobic exercise on treatment‐related acute toxicity in men receiving radical external beam radiotherapy for localised prostate cancer We retrospectively analysed acute radiation toxicity data for patients who had participated in a randomised controlled study in our centre in order to assess the impact of aerobic exercise on acute rectal and bladder morbidity during treatment. Data from 65 of 66 patients were analysed: 33 allocated into a control group (standard advice) and 33 into an exercise group (aerobic walking for 30 min at least three times per week) during 4 weeks of external beam radiotherapy; one patient in the exercise group withdrew after randomisation before starting radiotherapy. There was a trend towards less severe acute rectal toxicity in the exercise group with a statistically significant difference in mean toxicity scores over the 4 weeks of radiotherapy (P = 0.004), with no significant difference in bladder toxicity scores between the two groups (P = 0.123). The lack of an association for severity of bladder toxicity could be attributed to the confounding effect of lower urinary tract symptoms from their prostate cancer. Keeping active and being asked to adhere to a well‐defined exercise schedule appears to reduce the severity of rectal toxicity during radiotherapy to the prostate. 相似文献

The likely roles of Wnt signaling in regulating mammary stem cell behavior have been much discussed, in part because they
may underlie the oncogenic effects of Wnt signaling in mammary tissue. Two recent papers add important data to this field.
One tests directly the effects of purified Wnt protein on mouse mammary stem cells in culture and finds a specific increase
in the proportion of cells with self-renewing stem cell phenotypes. The second identifies a novel target gene of canonical
Wnt signaling that may be expressed in stem cells and is induced in both mouse and human mammary tumors associated with Wnt
pathway activation. 相似文献

Array comparative genomic hybridization studies were performed to further characterize cytogenetic abnormalities found originally by karyotype and fluorescence in situ hybridization in five clinical cases of distal 10q deletions, including several with complex cytogenetic rearrangements and one with a partial male-to-female sex-reversal phenotype. These results have enabled us to narrow the previously proposed critical regions for the craniofacial, urogenital, and neuropsychiatric disease-related manifestations associated with distal 10q deletion syndrome. Furthermore, we propose that haploinsufficiency of the DOCK1 gene may play a crucial role in the pathogenesis of the 10q deletion syndrome. We hypothesize that alteration of DOCK1 and/or other genes involved in regulation and signaling of multiple pathways can explain the wide range of phenotypic variability between patients with similar or identical cytogenetic abnormalities. 相似文献
