AI Article Synopsis
- Multifunctional nanoparticles made from MnFe₂O₄ are combined with chitosan to enhance magnetic drug delivery and hyperthermia for cancer treatment, while also serving as MRI contrast agents for diagnosis.
- The study details the synthesis and characterization of these nanoparticles, focusing on their stability in water and their ability to act as effective drug carriers due to the chitosan coating.
- The researchers examined how different concentrations of a surface-modifying agent (DMSA) and varying pH levels affect the magnetic properties, heat generation, and size of the nanoparticles.
Article Abstract
Multifunctional nanoparticles composed of MnFe₂O₄ were encapsulated in chitosan for investigation of system to combine magnetically-triggered drug delivery and localized hyperthermia for cancer treatment with the previously published capacity of MnFe₂O₄ to be used as an efficient MRI contrast agent for cancer diagnosis. This paper focuses on the synthesis and characterization of magnetic MnFe₂O₄ nanoparticles, their dispersion in water and their incorporation in chitosan, which serves as a drug carrier. The surface of the MnFe₂O₄ nanoparticles was modified with meso-2,3-di-mercaptosuccinic acid (DMSA) to develop stable aqueous dispersions. The nanoparticles were coated with chitosan, and the magnetic properties, heat generation and hydrodynamic size of chitosan-coated MnFe₂O₄ were evaluated for various linker concentrations and in a range of pH conditions.

: Brain tissue immersed in cerebrospinal fluid often exhibits complex mechanical behaviour, especially the nonlinear stress- strain and rate-dependent responses. Despite extensive research into its material properties, the impact of solution environments on the mechanical behaviour of brain tissue remains limited. This knowledge gap affects the biofidelity of head modelling.

Anti-Müllerian hormone (AMH) protects the ovarian reserve from chemotherapy, and this effect is most pronounced with Doxorubicin (DOX). However, DOX toxicity and AMH rescue mechanisms in the ovary have remained unclear. Herein, we characterize the consequences of these treatments in ovarian cell types using scRNAseq.

RNA N6-methyladenosine (m6A) plays diverse roles in RNA metabolism and its deregulation contributes to tumor initiation and progression. Clear cell renal cell carcinoma (ccRCC) is characterized by near ubiquitous loss of followed by mutations in epigenetic regulators , , and . Mutations in , a histone H3 lysine 36 trimethylase (H3K36me3), are associated with reduced survival, greater metastatic propensity, and metabolic reprogramming.
