Comparison of esophagus dose in breast cancer patients undergoing supraclavicular irradiation with and without esophagus countering.

Context: Esophagus toxicity and the risk of esophageal cancer are linked to radiation dose to the esophagus in breast cancer patients undergoing supraclavicular irradiation.

Aims: The aim of this study was to evaluate the impact of esophagus contouring on the dose received in the esophagus in breast cancer patients undergoing supraclavicular irradiation.

Setting And Design: This study included 30 treatment plans for breast cancer patients who received 50 Gy/25 fractions (2 Gy/fraction/day) using 3D-conformal radiation therapy (3D-CRT) to the whole breast or chest wall and supraclavicular.

Detection of the Early Cardiotoxic Effects of Doxorubicin-Containing Chemotherapy Regimens in Patients with Breast Cancer through Novel Cardiac Magnetic Resonance Imaging: A Short-term Follow-up.

Objectives: Many patients with breast cancer (BC) require cardiotoxic anthracycline-based chemotherapy. We intended to assess the early cardiotoxic effects of doxorubicin utilizing cardiac magnetic resonance (CMR) imaging.

Material And Methods: Forty-nine patients including 21 otherwise healthy females with BC at a mean age (±SD) of 47.

The role of cardiac magnetic resonance imaging in the detection and monitoring of cardiotoxicity in patients with breast cancer after treatment: a comprehensive review.

The use of chemotherapy medicines for breast cancer (BC) has been associated with an increased risk of cardiotoxicity. In recent years, there have been growing interests regarding the application of cardiovascular magnetic resonance (CMR) imaging, a safe and noninvasive modality, with the potential to identify subtle morphological and functional changes in the myocardium. In this investigation, we aimed to review the performance of various CMR methods in diagnosing cardiotoxicity in BC, induced by chemotherapy or radiotherapy.

Spectrophotometric determination of vitamin A in oils and fats.

A spectrophotometric method for determining vitamin A based on interaction with 50% trichloroacetic acid solution in dichloromethane was developed. The blue reaction product had a maximum absorption at 620 nm and obeyed Beer's law over the concentration range of 0.5-5.

Rapid spectrophotometric determination of ascorbic acid in citrus fruits.

A new spectrophotometric method has been developed for determining ascorbic acid in citrus fruits. The method is based on interaction between dimethoxydiquinone and ascorbic acid, followed by extraction with chloroform. The resulting chloroform solution gives a maximum absorption at 530 nm, a determination limit of 22.
