This study investigates whether Andrographolide-loaded Lactose β-Cyclodextrin (ALN-βCD) nanoparticles enhance cognitive function, particularly spatial learning and memory. The successful conjugation of lactose to β-cyclodextrin was confirmed via 1H NMR spectroscopy, facilitating neuronal cell entry. The solvent evaporation method was used to create the nanoparticles, which were characterised for particle size, PDI, zeta potential, and drug release. The nanoparticles exhibited a size of 247.9 ± 3.2 nm, a PDI of 0.5 ± 0.02, and a zeta potential of 26.8 ± 2.5 mV. FTIR and TEM analyses, along with in vitro drug release and BBB permeability studies, confirmed their stability and efficacy. Behavioural tests, including the Elevated Plus Maze, Y-Maze, Object Recognition, and Locomotor Activity tests, demonstrated significant improvements in memory, motor coordination, and exploration time in the nanoparticle-treated groups. The group treated with ALN-βCD at a dose of 100 mg/kg/p.o. showed superior cognitive performance compared to the group receiving free andrographolides (AG). Biochemical assays indicated a significant reduction in acetylcholinesterase activity and lipid peroxidation, suggesting increased acetylcholine levels and reduced oxidative stress. Histopathological examination showed improved neuronal function without toxicity. The results showed significant improvements (p < 0.001) in memory and cognitive abilities in experimental animals, highlighting the potential of ALN-βCD nanoparticles as a non-invasive treatment for memory loss. These promising findings warrant further exploration through clinical trials.
Many people who have recovered from coronavirus disease 2019 (COVID-19) have recently been diagnosed with black fungus – or mucormycosis – disease. Rhino-orbital mucormycosis is becoming more common in people with COVID-19, particularly in India. On its own, diabetes mellitus is a risk factor for severe COVID-19 and mucormycosis. The goal of this study is to conduct a review of the literature to determine the features of patients with mucormycosis and COVID-19. Increased mucormycosis in India appears to be the result of an unholy trifecta of diabetes (high hereditary incidence), corticosteroid overuse (increased blood glucose and opportunistic fungal infection), and COVID-19 (cytokine storm, lymphopenia, and endothelial damage). To limit the incidence of deadly mucormycosis, all efforts should be made to maintain optimum hyperglycemia, and only prudent evidence-based use of corticosteroids in patients with COVID-19 is advocated. In this review, we emphasize knowledge on diagnosis and therapy regarding black fungal mucormycosis, which is accompanied by post-SARS-CoV-2.
