The present investigation aims at developing microemulsion-based formulations for topical delivery of acyclovir. Various microemulsions were developed using isopropyl myristate/Captex 355/Labrafac as an oil phase, Tween 20 as surfactant, Span 20 as cosurfactant, and water/dimethylsulfoxide (1:3) as an aqueous phase. Transcutol, eucalyptus oil, and peppermint oil were used as permeation enhancers. In vitro permeation studies through laca mice skin were performed using Franz diffusion cells. The optimum formulation containing 2.5% Transcutol as the penetration enhancer showed 1.7-fold enhancement in flux and permeation coefficient as compared to marketed cream and ointment formulation. In vivo antiviral studies were performed in female Balb/c mice against induced herpes simplex virus I infection. A single application of microemulsion formulation containing 2.5% Transcutol given 24 h post-injection resulted in complete suppression of development of herpetic skin lesions.

Aim: The aim of the current study was to explore nano-formulation for effective neuroprotection by auranofin.
Background: Currently, the treatment options for various CNS disorders, particularly neurodegenerative disorders, are greatly constrained. A significant obstacle in this pursuit is the blood-brain barrier, a shielding covering that hinders the route of numerous biochemical treatments into the brain.

Objective: Wet distiller's grains (WDG) are rich in crude protein, yet challenging to preserve. Nevertheless, incorporating WDG into total mixed ration (TMR) silage holds promise for enhancing fermentation quality. This study investigated the effects of varying WDG proportions on nitrogen composition, fermentation quality, and microorganisms in TMR silage.

Frequent topical administration of hypotensive eye drops in glaucoma patients may lead to the development of dry eye disease (DED) symptoms, because of tear film destabilization and the adverse effects associated with antiglaucoma formulations. To address all this, in the current study preservative-free latanoprost-loaded (0.005 % w/v) synthetic phosphatidylcholine (1,2-dioleoyl-sn-glycero-3-phosphocholine 0.
