question:
It remains controversial whether the cure of H. pylori infection improves NUD symptoms.', 'To conduct a double-blind placebo-controlled single centre study with concealed allocation to investigate this question.', 'Ninety NUD patients with H. pylori infection were randomly assigned to either the treatment group (50 patients) or placebo group (40 patients). The treatment group received omeprazole, amoxycillin, clarithromycin and the placebo group received omeprazole and placebos for 7 days. Symptoms were assessed every week for up to 12 weeks after completion of medication by a symptom questionnaire. Alteration of histological parameters for gastritis was also evaluated.', 'The infection was cured in 41 out of 48 patients in the treatment group and none in the placebo group. There was no significant difference in the mean symptom scores at any assessment point up to 12 weeks between the treatment and placebo groups. Regarding histological parameters, activity and inflammation, not atrophy or intestinal metaplasia, were significantly improved in the treatment group.

question:
To compare rates of pelvic inflammatory disease (PID) among women who did and did not receive an intrauterine device (IUD) the day they sought emergency contraception (EC) or pregnancy testing.', 'Women, 15 to 45\xa0years of age, who sought EC or pregnancy testing from an urban family planning clinic completed surveys at the time of their clinic visit (August 22, 2011, to May 30, 2013) and 3 months after their clinic visit. The surveys assessed contraceptive use and symptoms, testing, and treatment for sexually transmitted infections (STI) and PID. We reviewed the medical records of participants who reported IUD placement within 3\xa0months of enrollment and abstracted de-identified electronic medical record (EMR) data on all women who sought EC or pregnancy testing from the study clinic during the study period.', 'During the study period, 1,060 women visited the study clinic; 272 completed both enrollment and follow-up surveys. Among survey completers with same-day IUD placement, PID in the 3\xa0months after enrollment was not more common (1/28 [3.6%]; 95% CI, 0%-10.4%) than among women who did not have a same-day IUD placed (11/225 [4.9%]; 95% CI, 2.7%-8.6%; p\xa0=\xa0.71). Chart review and EMR data similarly showed that rates of PID within 3\xa0months of seeking EC or pregnancy testing were low whether women opted for same-day or delayed IUD placement.

question:
The optimal repair of DNA lesions is fundamental for physiological processes. We asked whether the recruitment of HP1β, 53BP1 and BMI1 proteins to ultraviolet (UVA)-induced DNA lesions requires functional A-type lamins.', 'We found that UVA irradiation of nuclear lamina abolished the fluorescence of mCherry-tagged A-type lamins and destroyed the nuclear lamina as also observed by electron microscopy studies. Similarly, an absence of endogenous A- and B-type lamins was found in irradiated regions by UVA. However, irradiation did not affect the recruitment of HP1β, 53BP1 and BMI1 to DNA lesions. The UVA-induced shrinkage of the nuclear lamina, which anchors chromatin, explains why UVA-micro-irradiated chromatin is relaxed. Conversely, additional experiments with γ-irradiation showed that the nuclear lamina remained intact and the genome-wide level of HP1β was stable. Fluorescence intensity of HP1β and BMI1 in UVA-induced DNA lesions and level of HP1β after γ-irradiation were unaffected by deficiency in A-type lamins, whereas those parameters of 53BP1 were changed.
