Experimental Rodent Models of Vascular Dementia: A Systematic Review.

Vascular Dementia (VaD) occurs due to cerebrovascular insufficiency, which leads to decreased blood circulation to the brain, thereby resulting in mental disabilities. The main causes of Vascular Cognitive Impairment (VCI) are severe hypoperfusion, stroke, hypertension, large vessel disease (cortical), small Vessel Disease (subcortical VaD), strategic infarct, hemorrhage (microbleed), Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL), and Cerebral Amyloid Angiopathy (CAA), which leads to decreased cerebrovascular perfusion. Many metabolic disorders such as Diabetes Mellitus (DM), dyslipidemia, and hyperhomocysteinemia are also related to VaD.

Development and evaluation of PLGA polymer based nanoparticles of quercetin.

Quercetin is the most abundant antioxidant found in the human diet. Low aqueous solubility of quercetin limits its bioavailability and hence therapeutic effects. Therefore, the aim of the present study was to develop a poly lactide-co-glycolic acid (PLGA) polymer based nanoparticles of quercetin with a view to improve its aqueous solubility and examine the effect on its antioxidant and diuretic properties.

Enhanced oral bioavailability of insulin-loaded solid lipid nanoparticles: pharmacokinetic bioavailability of insulin-loaded solid lipid nanoparticles in diabetic rats.

Objective: Insulin is a hormone used in the treatment of diabetes mellitus. Multiple injections of insulin every day may causes pain, allergic reactions at injection site, which lead to low patient compliance. The aim of this work was to develop and evaluate an efficient solid lipid nanoparticle (SLN) carrier for oral delivery of insulin.
