Clin Chim Acta

September 2025

Department of Hematology and Blood Banking, School of Allied Medical Sciences, Iran University of Medical, Tehran, Iran. Electronic address:

Acute myeloid leukemia (AML) represents a genetically heterogeneous malignancy, with mutations in the nucleophosmin-1 (NPM1) gene identified as the most prevalent and clinically significant molecular biomarkers. These mutations play a crucial pivotal role in the realms of diagnosis, prognosis, and therapeutic decision-making. Although an ideal measurable residual disease (MRD) test has yet to be developed, there is increasing acknowledgment of the significance of advanced molecular methodologies for monitoring MRD in NPM1-mutated (NPM1) AML.

Bilirubin biosensors for liver disease management.

Clin Chim Acta

September 2025

Social Determinants of Health Research Center, Health Management and Safety Promotion, Tabriz University of Medical Sciences, Tabriz, Iran. Electronic address:

Bilirubin is a vital biomarker that plays a significant role in assessing liver function and diagnosing hemolytic disorders. While current detection methods are indeed sufficient for clinical practice, the accurate and timely detection of bilirubin levels remains essential for effective management of liver diseases. Enhanced detection capabilities through sensitive nanoscale biosensors can provide more precise monitoring, which may lead to earlier identification of abnormalities and improved patient outcomes.

Radiotherapy is a cornerstone in treating head and neck cancers, yet its effectiveness is often limited by factors such as hypoxia and cancer stem cells. This study evaluated the radiosensitizing potential of diosgenin in KB cancer cells and normal HDF cells exposed to 4 Gy X-rays, with or without diosgenin. Cell viability, apoptosis, cell cycle distribution, ROS production, and expression of intrinsic apoptosis-related genes were assessed using MTT assays, flow cytometry, and RT-qPCR, respectively.

Nanobubbles: An emerging therapeutic paradigm for targeted cancer therapy.

Bioorg Chem

August 2025

ENT and Head and Neck Research Center and Department, The Five Senses Health Institute, School of Medicine, Iran University of Medical Sciences, Tehran, Iran; Radiation Oncology Department, Iran University of Medical Sciences, Tehran, Iran. Electronic address:

Recently, nanobubbles (NBs) have emerged as a groundbreaking platform for drug and gene delivery in the targeted treatment of cancer because of their unique advantages. The nanoscale dimensions, stability, and responsiveness to external triggers-for example, ultrasound-allow for highly selective localization and controlled release of therapeutic agents in tumor tissues. This review highlights the capability of NBs, when combined with ultrasound activation, to significantly improve the intracellular uptake, penetration, and therapeutic efficacy of chemotherapeutic agents, thus diminishing their off-target toxicity.
