Radiation therapy delivered with hypofractionation, which involves the delivery of a higher dose per fraction in fewer fractions (generally with a lower total nominal dose) over a shorter overall treatment time, is an established therapeutic option at least for a selected group of early breast cancer patients after breast-conserving surgery. Optimal delivery of the tumor bed boost dose in terms...

A method is proposed for delivering an absorbed dose to a target during brachytherapy cervical cancer by using new applicator, which consists of annular part and two uterine canals. The design the applicator makes it possible implement required depth, taking into account anatomical features, widely cover cervix corporis womb with 100 % isodose irradiation, deliver planned dose. patient admitted...

Turnera aphrodisiacaWard (Turneraceae) has been traditionally used for the treatment of anxiety neurosis and as aphrodisiac, but no attempts have been made to investigate the plant systematically for its traditional claims. The current investigation was carried out ot isolate the bioactive constituent(s) from T. aphrodisiaca using bioactivity-guided fractionation. Antianxiety activityguided fra...

X-ray fluorescence nanotomography provides unprecedented sensitivity for studies of trace metal distributions in whole biological cells. Dose fractionation, in which one acquires very low dose individual projections and then obtains high statistics reconstructions as signal from a voxel is brought together (Hegerl & Hoppe, 1976), requires accurate alignment of these individual projections so as...

CARO 2016 _________________________________________________________________________________________________________ was sent to all 14 provincial cancer centres in 2013. The survey included 72 questions in four different categories: general/demographic, pre-treatment assessment, EBRT and BT questions. Results: The response rate was 100%. Ten out of 14 centres treated cervical cancer patients an...

Pancreatic cancer is a devastating disease with poor survival outcomes. Recent studies have shown that the addition of radiotherapy to chemotherapy in the setting of locally advanced pancreatic cancer did not improve overall survival outcome. These studies commonly utilize conventional radiotherapy treatment fractionation and technique (typically 3-D conformal radiotherapy or intensity modulate...

HE previous paper (DE SERRES and GILES 1953) has described the results T of experiments investigating the effects of fractionated doses of X-rays on the frequency of chromosome aberrations induced in Tradescantia microspores. The results of these studies demonstrate that there is a marked effect of X-ray dosage fractionation in reducing the yield of 2-hit aberration types and, further, that no ...
