Zinc-Phthalocyanine Loaded PLGA-PVA-Chitosan Nanosystem for the Enhancement of Antidiabetic Activity.

Zinc, one of the most common nutraceutical agents, proved to be effective for diabetes as it regulates the blood glucose level by inhibiting glucagon secretion. However, the hepatotoxicity of zinc creates necrosis, hepatic glycogen depletion, and apoptosis of hepatocytes at the concentration of 10 μg/kg. Phthalocyanine, a blue-colored compound, is an aromatic macrocyclic compound with good antioxidant ability owing to its heterocyclic nitrogen conjugation.

Phthalocyanine-based glucose-responsive nanocochleates for dynamic prevention of β-cell damage in diabetes.

Phthalocyanine is a blue-colored macrocyclic compound with excellent anti-oxidant and lipid-peroxidation abilities due to its intermolecular π-π stacking structure. Antioxidants inhibit intracellular reactive oxygen species formation and decrease oxidation defense ability of the enzymes in diabetes management. The present study aimed to fabricate concanavalin A conjugated phthalocyanine-loaded cochleates (Formulation PhConA) as a glucose-sensitive lipidic system and estimate its efficacy in streptozotocin-induced male Sprague Dawley diabetic rats for 28 days.

Diversified Applications of Self-assembled Nanocluster Delivery Systems- A State-ofthe- art Review.

Background: For the nanoparticulate system and the transportation of cellular elements for the fabrication of microelectronic devices, self-assembled nanoclusters arrange the components into an organized structure. Nanoclusters reduce transcytosis and increase endocytosis in intestinal mucin to strengthen the retrograde pathway that helps for delivery of actives to the Golgi apparatus.

Objectives: This review article focuses on the self-assembled nanoclusters for cellular transportation, applications of self-assembled structures in the delivery of essential elements like using a peptide in targeted and stimuli-responsive drug delivery systems, and self-assembly of tocopherol nanoclusters that promote vitamin E delivery across the endothelial barrier.

Multifaceted Applications of Genetically Modified Micro-organisms: A Biotechnological Revolution.

Background: Genetically modified micro-organisms like bacteria, viruses, algae and fungi are novel approaches used in the field of healthcare due to better efficacy and targeted delivery in comparison to conventional approaches.

Objectives: This review article focuses on the applications of genetically modified micro-organisms in the treatment of cancer, obesity and HIV infection. The gut microbiome causes metabolic disorders, however, the use of genetically modified bacteria alters the gut microbiota and delivers therapeutically effective drugs in the treatment of obesity.

Enhancement of immunopotentiation using tetanus toxoid-based nanoparticulate dissolvable microneedles.

The main objective of the present study was to prepare and evaluate dissolvable microneedle patch containing nanoparticles of tetanus toxoid without the use of any adjuvant and its immunopotentiation activity. Immunization with microneedles is a novel approach in vaccines delivery with advantages such as convenience, simple, and non-invasive therapy. The gelatin nanoparticles were prepared by a layer-by-layer coating method using polystyrene sulfonate (PSS), polyallylamine hydrochloride (PLA), and PLGA.
