Diabetic periodontitis presents a unique therapeutic challenge, primarily due to its chronic inflammatory profile and the associated bone loss driven by immune dysregulation. Metformin (Met) is recognized for its potent anti-inflammatory properties, yet its limited cellular uptake has hindered its clinical effectiveness in diabetic periodontitis. A tetrahedral framework nucleic acid (tFNA)-based delivery system is developed to enhance Met cellular uptake and investigate its effects on diabetic periodontitis in this study.

Transdermal drug delivery presents a compelling alternative to both needle injection and oral ingestion of medication, as it enhances patient adherence and convenience through its non-invasive and painless administration method. The use of microneedles penetrates the barrier of the stratum corneum, facilitating the sustained delivery of drugs across the skin. However, their efficacy has been limited by the slow diffusion of molecules and often requires external triggers.

Doxorubicin (DOX) is a powerful antineoplastic FDA-approved anthracycline-derived antibiotic and is considered as the most suitable intervention for solid tumors and hematological cancers therapy. However, its therapeutic application is highly limited due to acute and chronic renal, hematological and testicular toxicity. Oxidative stress, lipid peroxidation and apoptosis in germ cells as well as low sperm count, motility and disturbing steroidogenesis are the principal machineries of DOX-induced testicular toxicity.

Background: Piperine, a secondary metabolite, affects the antihyperlipidemic effect of Ezetimibe (EZ). Hyperlipidemia is one of the independent risk factors for cardiovascular disorders such as atherosclerosis. Antihyperlipidemic drugs are essential for reducing cardiovascular events and patient mortality.

Alzheimer's disease (AD) is the most frequent cause of dementia. Since there are complex pathophysiological mechanisms behind AD, and there is no effective treatment strategy, it is necessary to introduce novel multi-targeting agents with fewer side effects and higher efficacy. Polydatin (PD) is a naturally occurring resveratrol glucoside employing multiple mechanisms toward neuroprotection.
