OBJECTIVE To evaluate the rate of over-diagnosis of breast cancer 15 years after the end of the Malmö mammographic screening trial. DESIGN Follow-up study. SETTING Malmö, Sweden. SUBJECTS 42 283 women aged 45-69 years at randomisation. INTERVENTIONS Screening for breast cancer with mammography or not (controls). Screening was offered at the end of the randomisation design to both groups...

Introdution: The aim of this study was to evaluate and benchmark EGSnrc code in the simulation of 18 MV photon beam produced by Siemens Oncor® linear accelerator. Methods: This study was conducted in a comparative and simulation based on experience method. The Beamnrc code was used to model the accelerator head and generate phase space files. The phase space files were obtained with the fo...
We approximately compute the normalization constant of the first infrared renormalon of the pole mass (and the singlet static potential). Estimates of higher order terms in the perturbative relation between the pole mass and the MS mass (and in the relation between the singlet static potential and αs) are given. We define a matching scheme (the renormalon subtracted scheme) between QCD and any ...

Objective(s): The purpose of this study was to investigate cytotoxicity and membrane toxicity effects induced by Mesobuthus eupeus venom (MEV) on the HT-29 cell line. Materials and Methods: To determine the in vitro cytotoxicity via MTT assays, HT-29 (as cancer cell line) and Hek-293T (as normal cell) were treated through different conce...
This study aimed to analyze risk factors for lack of Pap smear screening among menopausal women. This population-based study evaluated 456 women 45-69 years of age (mean 58.7; SD 5.7), with age at menopause 48.0 years (SD 5.0) living in the urban area of Maringá, Paraná State, Brazil. Most reported having 7 years of schooling or less, were married or living with a partner, had paid work, were s...
