Novel Spectroscopic Studies of the Interaction of Three Different Types of Iron Oxide Nanoparticles with Albumin.

In the present work, we studied the interactions of three types of iron oxide nanoparticles (IONPs) with human serum albumin (HSA) by fluorescence and UV-Vis spectroscopy. The determined binding parameters of the reactions and the thermodynamic parameters, including ΔHo, ΔSo, and ΔGo indicated that electrostatic forces play a major role in the interaction of IONPs with HSA. These measurements indicate a fluorescent quenching mechanism based on IONPs-HSA static complex formation.

Development of Nanocomposite Microspheres for Nasal Administration of Deferiprone in Neurodegenerative Disorders.

Elevated brain iron levels are characteristic of many neurodegenerative diseases. As an iron chelator with short biological half-life, deferiprone leads to agranulocytosis and neutropenia with a prolonged therapeutic course. Its inclusion in sustained-release dosage forms may reduce the frequency of administration.

Idebenone-Loaded Nanocomposite Microspheres for Nasal Administration-A Perspective in the Treatment of Alzheimer's Disease.

Background: Alzheimer's disease results in neurodegeneration and is characterized by an accumulation of abnormal neuritic lesions and intracellular aggregates of hyperphosphorylated Tau proteins in the cerebrum. That leads to progressive decline in memory, thinking, and learning skills. Oxidative stress has been shown to play a significant role in the pathogenesis of Alzheimer's disease.

Emerging Therapeutic Potential of Polyphenols from L. in Viral Infections, Including SARS-CoV-2.

The existing literature supports the anti-inflammatory, antioxidant, and antiviral capacities of the polyphenol extracts derived from L. These extracts exhibit potential in hindering viral replication by inhibiting enzymes like DNA polymerase and reverse transcriptase. The antiviral properties of L.

Effect of a Ketogenic Diet on Oxidative Posttranslational Protein Modifications and Brain Homogenate Denaturation in the Kindling Model of Epilepsy in Mice.

This study focused on the ketogenic diet (KD) effects on oxidative posttranslational protein modification (PPM) as presumptive factors implicated in epileptogenesis. A 28-day of KD treatment was performed. The corneal kindling model of epileptogenesis was used.
