Evaluation of tumor-colonizing strains using the chick chorioallantoic membrane model.

The chick embryo chorioallantoic membrane (CAM) tumor model is a valuable preclinical model for studying the tumor-colonizing process of serovar Typhimurium. It offers advantages such as cost-effectiveness, rapid turnaround, reduced engraftment issues, and ease of observation. In this study, we explored and validated the applicability of the partially immune-deficient CAM tumor model.

Targeting unique ligand binding domain structural features downregulates DKK1 in Y537S ESR1 mutant breast cancer cells.

Resistance to endocrine therapies remains a major clinical hurdle in breast cancer. Mutations to estrogen receptor alpha (ERα) arise after continued therapeutic pressure. Next generation selective estrogen receptor modulators and degraders/downregulators (SERMs and SERDs) show clinical efficacy, but responses are often non-durable.

Polypharmacy and cumulative anticholinergic burden in older adults hospitalized with fall.

Introduction: Polypharmacy is a growing phenomenon associated with adverse effects in older adults. We assessed the potential confounding effects of cumulative anticholinergic burden (ACB) in patients who were hospitalized with falls.

Methods: A noninterventional, prospective cohort study of unselected, acute admissions aged ≥ 65 years.
