Article Abstract
Combination chemotherapy presents a promising approach to overcome multidrug resistance in cancer treatment. However, conventional delivery systems struggle to achieve synchronized co-delivery of hydrophilic and hydrophobic therapeutics with tumor-specific targeting and controlled release. Here, we developed a multifunctional nanocarrier integrating poly (lactic-co-glycolic acid) nanoparticles with polydopamine and programmable nucleic acids. Within this system, the hydrophobic core encapsulates lipophilic drugs, while the surface nucleic acid architecture enables hydrophilic drug loading via molecular intercalation. Furthermore, tumor-targeting aptamers guide selective cellular uptake, and a tumor microenvironment-responsive mechanism ensures spatiotemporally controlled drug release. As demonstrated experimentally, this unified platform demonstrates promising antitumor activity with potential advantages in drug delivery efficiency. By combining targeted delivery, differential drug loading, and stimuli-triggered release, the design establishes a modular framework for precision combination therapies, thereby advancing adaptable nanomedicine in oncology.

Purpose: The purpose of this document is to review current methods for cervical ripening and to summarize the effectiveness of these approaches based on appropriately conducted outcomes-based research. This document focuses on cervical ripening in individuals with term, singleton, vertex pregnancies with membranes intact, because this is the population in whom most studies were conducted. For more information on recommended timing of delivery based on maternal, fetal, and obstetric conditions and on labor management, refer to: American College of Obstetricians and Gynecologists (ACOG) Committee Opinion No.

Neuropeptide Y (NPY) and the voltage-gated potassium channel Kv1.3 are closely associated with breast cancer progression and apoptosis regulation, respectively. NPY receptors (NPYRs), which are overexpressed in breast tumors, contribute to tumor growth, migration, and angiogenesis.

Purpose: Glioblastoma (GBM) remains one of the most aggressive primary brain tumors with poor survival outcomes and a lack of approved therapies. A promising novel approach for GBM is the application of photodynamic therapy (PDT), a localized, light-activated treatment using tumor-selective photosensitizers. This narrative review describes the mechanisms, delivery systems, photosensitizers, and available evidence regarding the potential of PDT as a novel therapeutic approach for GBM.

Acute ischemic stroke (AIS) remains a leading cause of mortality and long-term disability globally, with survivors at high risk of recurrent stroke, cardiovascular events, and post-stroke dementia. Statins, while widely used for their lipid-lowering effects, also possess pleiotropic properties, including anti-inflammatory, endothelial-stabilizing, and neuroprotective actions, which may offer added benefit in AIS management. This article synthesizes emerging evidence on statins' dual mechanisms of action and evaluates their role in reducing recurrence, improving survival, and mitigating cognitive decline.

Target-controlled infusion (TCI) systems, originally developed for intravenous drug administration of anesthetic drugs, enable precise drug delivery based on pharmacokinetic-pharmacodynamic (PKPD) models. While widely used in the operating room, their application in the intensive care unit (ICU) remains limited despite the complexity of drug dosing in critically ill patients. This scoping review evaluates existing evidence on the use of TCI systems in ICU settings, focusing on sedation, analgesia, and antibiotic administration.
