Asthma is a highly relevant disorder that can be induced by many environmental factors such as allergens and pollutants. One of the most critical pathological symptoms of asthma is airway inflammation. In order to identify a cause of respiratory inflammation, we thoroughly examine the unique role of reactive oxygen species (ROS). Evidence supports that the inhalation of aggravating compounds such as allergens can promote the increased generation of ROS. Accordingly, ROS have a proven role in the cellular signaling cascades of many respiratory diseases that cause respiratory inflammation, including asthma. Although there is no known cure for asthma, current treatments effectively lessen the inflammation symptom. Based on the investigations of asthma pathogenesis and the mechanism of ROS formation, we have identified several novel anti-inflammatory therapeutic treatments, shedding light on a fundamental understanding for the cure of this disorder. In this review, we will outline the pathogenesis of asthma and its relationship to ROS, oxidative stress, and pulmonary inflammation.

Anticancer potential of nerolidol on acute lymphoblastic leukemia cells through the interactions with the NF-κB/STAT-3 and PI3K/Akt signaling pathways.
Adv Clin Exp Med
January 2025
Department of Hematology, Rheumatology and Immunology, The First People's Hospital of Xianyang, China.
Background: Leukemia may form at any age, from newborns to the elderly, and accounts for considerable mortality worldwide.
Objectives: Nerolidol (NRD) is isolated from the aromatic florae oils and was found to have anticancer activities. However, the role of NRD in antiproliferative and apoptosis actions in acute lymphoblastic leukemia (ALL) is unclear.

Shree S. K. Patel College of Pharmaceutical Education and Research, Ganpat University, Kherva, 384012, India.
Aims: This study aimed to develop Imatinib Mesylate (IMT)-loaded Poly Lactic-co-Glycolic Acid (PLGA)-D-α-tocopheryl polyethylene glycol succinate (TPGS)- Polyethylene glycol (PEG) hybrid nanoparticles (CSLHNPs) with optimized physicochemical properties for targeted delivery to glioblastoma multiforme.
Background: Glioblastoma multiforme (GBM) is the most destructive type of brain tumor with several complications. Currently, most treatments for drug delivery for this disease face challenges due to the poor blood-brain barrier (BBB) and lack of site-specific delivery.
Morphine-Induced Elevation of Reactive Oxygen Species Attenuates Chemotherapy Efficacy in Diverse Cancer Cell Types.
Curr Mol Med
January 2025
Department of Anesthesiology, Baoan Central Hospital of Shenzhen, Shenzhen, Guangdong Province, China.
Background: Morphine, a mu-opioid receptor (MOR) agonist commonly utilized in clinical settings alongside chemotherapy to manage chronic pain in cancer patients, has exhibited contradictory effects on cancer, displaying specificity toward certain cancer types and doses.
Objective: The aim of this study was to conduct a systematic assessment and comparison of the impacts of morphine on three distinct cancer models in a preclinical setting.
Methods: Viability and apoptosis assays were conducted on a panel of cancer cell lines following treatment with morphine, chemotherapy drugs alone, or their combination.
Oral Biomimetic Nanotherapeutics for Ulcerative Colitis Targeted Treatment by Repairing Intestinal Epithelial Barrier and Restoring Redox Homeostasis.
ACS Appl Mater Interfaces

Department of Pharmaceutics, School of Pharmacy, Ningxia Medical University, No. 1160 Shengli South Street, Yinchuan 750004, PR China.
The structural disruption of intestinal barrier and excessive reactive oxygen/nitrogen species (RONS) generation are two intertwined factors that drive the occurrence and development of ulcerative colitis (UC). Synchronously restoring the intestinal barrier and mitigating excess RONS is a promising strategy for UC management, but its treatment outcomes are still hindered by low drug accumulation and retention in colonic lesions. Inspired by intestine colonizing bacterium, we developed a mucoadhesive probiotic -mimic entinostat-loaded hollow mesopores prussian blue (HMPB) nanotherapeutic (AM@HMPB@E) for UC-targeted therapy via repairing intestinal barrier and scavenging RONS.

Background: The ECM (extracellular matrix) provides the microenvironmental niche sensed by resident vascular smooth muscle cells (VSMCs). Aging and disease are associated with dramatic changes in ECM composition and properties; however, their impact on the VSMC phenotype remains poorly studied.
Methods: Here, we describe a novel in vitro model system that utilizes endogenous ECM to study how modifications associated with age and metabolic disease impact the VSMC phenotype.
