Comparative effectiveness of primary tumor resection versus chemotherapy in patients with asymptomatic unresectable metastatic colorectal cancer: a retrospective cohort study using the target trial emulation framework.

Patients who undergo primary tumor resection (PTR) reportedly have significantly higher overall survival (OS) than those who do not undergo this procedure. However, this result is only evident in past retrospective studies, and clinical trial results did not show the same trend. Thus, it remains unclear whether primary tumor resection effectively increases survival in patients with metastatic colorectal cancer (mCRC) across different study designs.

Benefits of Herbal Medicine on Bone Mineral Density in Osteoporosis: A Meta-Analysis of Randomized Controlled Trials.

Bone mineral density (BMD) has been validated not only for the diagnosis of osteoporosis but also for prediction of the risk of osteoporosis-related fractures. The purpose of this paper was to investigate the overall benefits of herbal medicines on BMD using a meta-analytic method. Systematic searches in PubMed, Medline, Cochrane Central, and China National Knowledge Infrastructure were performed for eligible studies.

Effect of sertraline on Ca²⁺ fluxes in rabbit corneal epithelial cells.

The effect of sertraline, a selective serotonin reuptake inhibitor (SSRI), on cytosolic free Ca²⁺ concentrations ([Ca²⁺](i)) in a rabbit corneal epithelial cell line (SIRC) is unclear. This study explored whether sertraline changed basal [Ca²⁺](i) levels in suspended SIRC cells by using fura-2 as a Ca²⁺-sensitive fluorescent dye. Sertraline at concentrations between 10-100 μM increased [Ca²⁺](i) in a concentration-dependent manner.
