Background: Annually, approximately 1.7 million women are diagnosed with breast cancer worldwide. Engaging in regular physical activity (PA) post-diagnosis brings significant health benefits, enhancing breast cancer survivors' (BCS) prognosis and overall health-related quality of life (HRQoL). Despite these benefits, a low percentage of Chinese BCS adhere to the recommended moderate-to-vigorous PA levels. This highlights the need for innovative PA interventions tailored for BCS management. eHealth technology, such as fitness wearables and apps, presents an opportunity to improve BCS healthcare by offering personalized exercise programs.
Methods: This study focuses on developing a precision eHealth PA program for 200 Chinese BCS in Guangdong Province, using a custom micro-application and a smart band for a 12-month trial. All participants will receive a Huawei Smart Band and be divided into 1) a personalized intervention group, receiving daily PA tracking and feedback, and 2) a control group receiving standard care. The primary outcome is PA and secondary outcomes include biomarkers, weight and body composition, functional fitness, HRQoL, and individual beliefs. Outcomes will be assessed at baseline, 6 months, and 12 months (endpoint). Successful outcomes could revolutionize PA programs for Chinese BCS, providing a model for future eHealth interventions.

In this study, we synthesized 12 monofunctional tridentate ONS-donor salicylaldimine ligand ()-based Ru(II) complexes with general formula [(Ru()(-cymene)]·Cl (-), characterized by H NMR, C NMR, UV, FT-IR spectroscopy, HR-ESI mass spectrometry, and single-crystal X-ray analysis showing ligand's orientation around the Ru(II) center. All 12 of these 12 complexes were tested for their anticancer activities in multiple cancer cells. The superior antitumor efficacy of , , and was demonstrated by reduced mitochondrial membrane potential, impaired proliferative capacity, and disrupted redox homeostasis, along with enhanced apoptosis through caspase-3 activation and downregulation of Bcl-2 expression.

Background: To investigate the performance of contrast-enhanced ultrasound(CEUS) parameters of metastatic axillary lymph nodes (ALNs) before and after two courses of neoadjuvant chemotherapy (NAC) in breast cancer patients in predicting the efficacy of NAC.
Methods: A total of 41 postoperative breast cancer patients were selected. All patients underwent NAC, and ALN biopsy was positive before chemotherapy.

Unlabelled: Engineered three-dimensional (3D) tissue culture platforms are useful for reproducing and elucidating complex in vivo biological phenomena. Spheroids, 3D aggregates of living cells, are produced based on physicochemical or microfabrication technologies and are commonly used even in cancer pathology research. However, conventional methods have difficulties in constructing 3D structures depending on the cell types, and require specialized techniques/lab know-how to reproducibly control the spheroid size and shape.

Mucinous carcinoma of the breast, also known as colloid carcinoma, is an uncommon type of differentiated adenocarcinoma, representing only 2% of all invasive breast carcinomas. It usually occurs in women ≥ 60 years of age. Mucinous carcinoma is characterized by clusters of epithelial tumour cells suspended in pools of extracellular mucin and is further divided in 2 subgroups, pure and mixed.
