Implantable, 3D-Printed Alginate Scaffolds with Bismuth Sulfide Nanoparticles for the Treatment of Local Breast Cancer via Enhanced Radiotherapy.

Surgical removal of tumor tissue remains the primary clinical approach for addressing breast cancer; however, complete tumor excision is challenging, and the remaining tumor cells can lead to tumor recurrence and metastasis over time, which substantially deteriorates the life quality of the patients. With the aim to improve local cancer radiotherapy, this work reports the fabrication of alginate (Alg) scaffolds containing bovine serum albumin (BSA)-coated bismuth sulfide (BiS@BSA) nanoradiosensitizers using three-dimensional (3D) printing. Under single-dose X-ray irradiation in vitro, Alg-BiS@BSA scaffolds significantly increase the formation of reactive oxygen species, enhance the inhibition of breast cancer cells, and suppress their colony formation capacity.

Association between carotid intima-media thickness and presence of coronary artery disease in chronic obstructive pulmonary disease patients.

Objective: Chronic obstructive pulmonary disease (COPD) is a risk factor for cardiovascular disease (CVD). Carotid intima-media thickness (CIMT) is the sign of subclinical atherosclerosis. Therefore, the aim of this study was to evaluate whether CIMT measurement is related with significant coronary artery disease (CAD) in patients with COPD, similar to those without COPD.

Forced expiratory volume in one second can predict SYNTAX score in patients with chronic obstructive pulmonary disease.

Background: The SYNTAX score is an angiographic score that predicts coronary artery disease (CAD) complexity. It has been shown to be useful for decision making about percutaneous coronary intervention or coronary artery bypass grafting among patients with CAD. Higher SYNTAX scores are indicative of more complex disease.
