Background: Microvascular dysfunction (MVD) is a recognized sign of disease in heart failure progression. Intact blood vessels exhibit abnormal vasoreactivity in early stage, subsequently deteriorating to rarefaction and reduced perfusion. In managing heart failure with preserved ejection fraction (HFpEF), earlier diagnosis is key to improving management.

Nimodipine (NIMO) is used to treat ischemic nerve injury from subarachnoid hemorrhage (SAH), but its low aqueous solubility limits clinical safety and bioavailability. This study aims to improve NIMO's solubility by preparing inclusion complexes with sulfobutylether-β-cyclodextrin (SBE-β-CD), reducing the limitations of Nimotop injection, including vascular irritation, toxicity, and poor dilution stability. The NIMO-SBE-β-CD inclusion complex (NIMO-CD) was characterized in both liquid and solid states through phase solubility studies and methods including DSC, FT-IR, XRD, and SEM.

Chronic kidney disease (CKD) is a conceivable new risk factor for cognitive disorder and dementia. Uremic toxicity, oxidative stress, and peripheral-central inflammation have been considered important mediators of CKD-induced nervous disorders. Nitric oxide (NO) is a retrograde neurotransmitter in synapses, and has vital roles in intracellular signaling in neurons.

While cisplatin is an effective anti-tumor treatment, it induces ototoxicity through mechanisms involving DNA damage, oxidative stress, and programmed cell death. Rho-associated coiled-coil-containing protein kinase (ROCK) is essential for numerous cellular processes, including apoptosis regulation. Studies have suggested that ROCK inhibitors could prevent apoptosis and promote regeneration.
