Reproductive hormones and reactive oxygen species produced by either hormonal or aerobic metabolism have been implicated in carcinogenesis of the breast and disease progression. Perturbations in the homeostasis of female reproductive hormones and oxidative stress indices in breast cancer (BCa) could be used for monitoring disease prognosis. ⋯ Postmenopausal women with BCa at different stages have increased estradiol, antioxidants, lipid peroxidation, and oxidative stress index suggesting that these indices may be useful for clinical assessment and monitoring progression of breast cancer.

Timing of laparoscopic cholecystectomy (LC) in acute cholecystitis (AC) is still debated. ⋯ LC can safely be performed within 7 days of admission in cases of AC.

To evaluate the effect of various aging periods and different surface preparation methods on microtensile bond strength (μTBS) for composite repair. ⋯ Different surface preparation methods, various aging periods, and the interaction of both affected the repair μTBS of the tested nanohybrid composite resin.

The present study aimed to investigate the potential of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and mean platelet volume (MPV) as prognostic markers in tinnitus patients at inflammatory process. ⋯ Our results confirm that elevated NLR, PLR and MPV values has been suggested to be a useful inflammatuar prognostic biomarker of tinnitus patients.

To evaluate the effect of multiple-use and sterilization on cyclic fatigue and shaping ability of heat-treated nickel-titanium (NiTi) rotary instruments. ⋯ The effects of repeated use and autoclaving on the cyclic fatigue resistance of HyFlex CM, ProTaper Next, and Twisted File were not significant. Canal transportation increased mostly in the apical region. The amount of resin removal decreased as the number of use increased for ProTaper Next and Twisted File instruments.
