X-Type hexa-nano-ferrites were prepared using a co-precipitation route, coated with Chitosan, and synthesized into a ferrite chitosan curcumin nanoparticle system. This combination enhances curcumin’s therapeutic properties, chitosan’s bioavailability, and ferrite’s magnetic targeting potential, offering improved cellular uptake and diagnostic applications. Nandrolone decanote (ND), one of the class II anabolic androgenic steroids (AASs), quickly spreading as a class of medications used in both clinical and illegal settings. AAS can enhance tolerance to exercise, so they are taken illegally by bodybuilders and adolescents. However, the abuse of AASs can lead to serious and irreversible organ toxicity. This study designed to investigate the therapeutics effect of nano ferrite chitosan curcumin nanoparticles (NF-CH-CurNPs) against ND induced hepatic toxicity, proliferation, inflammation, oxidative stress, and DNA damage in male rats. 48 adult male rats assigned to 6 groups [1st Gp, control; 2nd Gp, CurNPs; 3rd Gp, NF-CH-CurNPs; 4th Gp, ND; 5th Gp, ND + CurNPs; 6th Gp. ND + NF-CH-CurNPs]. Current results revealed, a significant elevation in the levels of aspartate transaminase (AST), alanine transaminase (ALT), total proteins, liver DNA damage, injury, malondialdehyde (MDA), proliferating cell nuclear antigen (PCNA), tumor necrosis factor alpha (TNFα) and a significant depletion in albumin, catalase, superoxide dismutase (SOD), reduced glutathione (GSH) after ND administration as compared to control and CurNPs groups. Treatment of ND with CurNPs or NF-CH-CurNPs significantly improved liver functions, structure, oxidative stress, DNA damage, PCNA, and TNFα expressions, with NF-CH-CurNPs showing potential for scavenging free radicals.

Modulation of oxidative stress and P53/PCNA signaling by glucosodiene-loaded nanoferrites (GLONF) in ehrlich solid tumor–induced hepatotoxicity
2026
Ehrlich solid tumors are commonly used as a model to study tumor growth and evaluate potential anticancer therapies. Current study aimed to assess the curative efficacy of glucosodiene Loaded over Nanoferrites (GLONF) against Ehrlich solid tumor (EST) induced hepatotoxicity. Fifty female mice were randomly allocated into five equal groups (Control; GLONF; EST; GLONF + EST; EST+GLONF). Our findings revealed that the EST group exhibited significantly increased levels of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), hepatic injury indices, malondialdehyde (MDA), proliferating cell nuclear antigen
(
PCNA), and apoptotic p53, while showing significant depletion of albumin, total proteins, catalase, superoxide dismutase (SOD) and reduced glutathione (GSH) when compared to the control group. GLONF post-treatment (EST+ GLONF) is a highly effective strategy, demonstrating potent antitumor where it reduced tumor size, hepatoprotective, and antioxidant actions, restoring liver integrity, modulating key molecular markers and improving histological and immunohistochemical profiles.

Antineoplastic drugs
2025
Nanoscale materials can improve cancer treatment by safely and efficiently delivering chemotherapeutic drugs. This study was designated to load the anticancer drug doxorubicin (DOX) into chitosan-coated Pb2Mn2Fe12O22 magnetic nanoparticles (CT-MNPs) and compare their physicochemical and biological effects with free drug, in addition to the therapeutic role of DOX-CT-MNPs to acting efficaciously in restraint of cancer cells growth and evolution using Ehrlich solid tumor model (EST). Forty female mice were randomly and equally split into four groups (EST; EST + Free DOX; EST + CT-MNPs; and EST + DOX-CT-MNPs). Our findings show that treating EST with DOX, either free or loaded on CT-MNPs, inhibits tumour growth by producing oxidative stress, disrupting the antioxidant system, activating apoptosis, and arresting the cell cycle. Furthermore, DOX loaded on CT-MNPs had greater anticancer activity than DOX in its free form. This highlights the potential advantages of CT-MNPs in tumour therapy and drug delivery.

Light and ultrastructural study in the propylthiouracil-induced hypothyroid rat heart ventricles and the ameliorating role of folic acid
2012
Thyroid hormones have marked effects on the growth, development, and metabolic function of virtually all organs and tissues. Thyroid status is an important determinant of cardiovascular function. The present work studied the histopathological and ultrastructural changes in the hypothyroid rat left ventricle at post-pubertal stage, in addition to the ameliorating role of folic acid. A total of 50 male albino rats were randomly divided into 5 groups (group I, control; group II, folic acid; group III, propylthiouracil-induced hypothyroid rats; group IV, co-treatment with folic acid; group V, post-treatment). In order to ensure the hypothyroid state, the level of serum triiodothyronine (T3) and thyroid stimulating hormone (TSH) through the dose period was regularly determined. The TSH levels were significantly higher while T3 levels were significantly lower in hypothyroid rats when compared to control group. The high-performance liquid chromatography analysis showed an increase in homocysteine (Hcy) in the hypothyroid rats group when compared to the control group. The histopathological studies of the ventricle in hypothyroid rats revealed hydrophobic changes in myofibrillar structure with striations, myocardial atrophy, nuclear pyknosis, cytoplasmic vacuoles, and cytoplasmic eosinophilia. Transmission electron micrographs in the myocardium of hypothyroid rats revealed a marked reduction in muscle fibre mass, a marked degeneration of muscle fibres, swollen mitochondria, dilated sarcoplasmic reticulum and more prominent perinuclear oedema observed in the cardiac myocytes. In co-treated hypothyroid rats with folic acid, a regular arrangement of muscle fibres, mild swelling of myofibrillar structure with striations and no continuity with adjacent myofibrils were observed while the post-treated hypothyroid rat with folic acid showed normal architecture of myofibrillar structure with striations and continuity with adjacent myofibrils. In conclusion, our results indicated that folic acid had ameliorative effect against cardiac damage induced by 6-n-propyl-2-thiouracil and the best results were found in case of using the folic acid as an adjuvant therapy after returning to the euthyroid state.
