Background: Radiofrequency catheter ablation (RFCA) has become an important strategy for treating atrial fibrillation (AF), and postoperative recurrence represents a significant and actively discussed clinical concern. The recurrence after RFCA is considered closely related to inflammation. Systemic immune inflammation index (SII) is a novel inflammation predictor based on neutrophils, platelets, and lymphocytes, and is considered a biomarker that comprehensively reflects the immune inflammatory status of the body.

Article Synopsis
  • This study compares two methods for implanting implantable venous access ports (IVAPs) in breast cancer patients, focusing on patient comfort, surgery duration, and complications.
  • Results show that the Axillary vein/Subclavian vein (AxV/SCV) approach provides significantly better patient comfort and shorter surgery time compared to the Internal jugular vein (IJV) method.
  • However, the AxV/SCV approach is associated with a higher risk of early complications, particularly catheter misplacement, while both methods overall have a low risk of complications.

Selenate and sulfide are both contaminants which severely pollute water bodies. Respective bioremediation of selenate- and sulfide-contaminated wastewaters requires abundant electron donors and acceptors. Here, we present a novel concept coupling biological selenate to selenite (shortcut deselenization) and chemical sulfide-driven selenite reduction, to remove multiple pollutants simultaneously.

Background: Internal jugular vein (IJV) and axillary vein/subclavian vein (AxV/SCV) are commonly used for implantable venous access port (IVAP) implantation in breast cancer (BC) patients with chemotherapy. Previous studies focused on complications between these different approaches and ignored patient comfort. In this study, we aim to compare patient comfort between IJV and AxV/SCV approaches, as well as surgery duration and complications.

CD44 is a marker of cancer stem cell (CSC) in many types of tumors. Alternative splicing of its 20 exons generates various CD44 isoforms that have different tissue specific expression and functions, including the CD44 standard isoform (CD44s) encoded by the constant exons and the CD44 variant isoforms (CD44v) with variant exon insertions. Switching between the CD44v and CD44s isoforms plays pivotal roles in tumor progression.
