BACKGROUND/AIMS The ultraviolet (UV) portion of sunlight is involved in the induction and development of skin cancers against which a limited photoprotection may be provided by reduced time of exposure, clothing, and sunscreen applications. The concept of an effective, safe, systemic photoprotection will circumvent many of the shortcomings. The UV-induced oxidative stress is a cause of DNA dama...
Increases in oxidative stress or decreases in antioxidant capacity, or redox imbalance, are known to alter physiological function and has been suggested to influence performance. To date, no study has sought to manipulate this balance in the same participants and observe the impact on physiological function and performance. Using a single-blind, placebo-controlled, and counterbalanced design, t...

هدف: هدف پژوهش حاضر، ساخت و اعتبارسنجی سیاهه آسیب‌شناسی روانشناختی نوجوانان در فضای مجازی بود. روش: روش آمیخته اکتشافی (کیفی-کمی) بدین منظور با استفاده از تحلیل مضمون مقالات مصاحبه‌های انجام‌شده متخصصان فعال مجازی، آسیب ها شناسایی شدند بر اساس آن ای ساخته شد. جامعه آماری بخش کیفی شامل مقالات، اساتید دانشگاه های اراک، اصفهان، امام خمینی قزوین شهر اراک بودند که نمونه هدفمند آنها انتخاب کمی بو...
The correlation of glutathione S-transferase (GST) M1/T1 genetic polymorphisms with oxidative stress-related chronic diseases was proved recently. The aim of the present study was to investigate the association of GSTM1/T1 genetic polymorphisms with antioxidant biomarkers and consumption of fruits and vegetables (F&V) in healthy subjects. In this study, for conducting a 3 d dietary survey, 190 ...
The Bi-Air (BA) dual-trace 25 mm filter cassette was described, and its performance for the collection of Aspergillus/Penicillium (Asp/Pen) and Stachybotrys type spores in a clam-air settling chamber was compared to that of the Air-O-Cell (AOC) cassette. The BA produced duplicate sample traces, the sample traces were confined to two small, welldefined areas on the filter, and the small size of ...

In side-channel analysis, the waveforms can be acquired misaligned. Several algorithms have been put forward to resynchronize signals, as a pretreatment before the attack proper. In this article, we examine two of them, namely amplitude-only and phase-only correlation (abridged AOC and POC), and introduce a third one, called thresholdPOC (T-POC) that corrects a flaw of the phase-only correlatio...
BACKGROUND No biomarker is available to predict prognosis of patients with advanced ovarian cancer (AOC) and guide the choice of chemotherapy. We performed a prospective-retrospective biomarker study within the MITO2 trial on the treatment of AOC. PATIENTS AND METHODS MITO2 is a randomised multicentre phase 3 trial conducted with 820 AOC patients assigned carboplatin/paclitaxel (carboplatin: ...
The present study investigated the effects of xanthophyll supplementation on production performance, antioxidant capacity (measured by glutathione peroxidase, superoxide dismutase (SOD), catalase, total antioxidant capacity (T-AOC), and reduced glutathione:oxidised glutathione ratio (GSH:GSSG)) and lipid peroxidation (measured by malondialdehyde (MDA)) in breeding hens and chicks. In Expt 1, 43...
