COVID-19 associated complications and potential therapeutic targets.

The global pandemic COVID-19, caused by novel coronavirus SARS-CoV-2, has emerged as severe public health issue crippling world health care systems. Substantial knowledge has been generated about the pathophysiology of the disease and possible treatment modalities in a relatively short span of time. As of August 19, 2020, there is no approved drug for the treatment of COVID-19.

Exploring molecular dynamics simulation to predict binding with ocular mucin: An in silico approach for screening mucoadhesive materials for ocular retentive delivery systems.

In recent times, molecular dynamic (MD) simulations have been applied in the area of drug delivery, as an in silico tool to predict the behaviour of nanoparticles with respect to their interaction with larger biological entities like bilayer membranes, DNA and dermal surface. However, the predictions must be systematically evaluated by extensive studies with actual biological entities in order to deem the in silico models accurate. Thus, in the present study, MD simulation was used to screen ligands with respect to ocular mucoadhesion.

Liposils: An effective strategy for stabilizing Paclitaxel loaded liposomes by surface coating with silica.

The present work aims at improving stability of paclitaxel (PTX) loaded liposomes by its coating with silica on the surface by a modified sol-gel method. Effect of various components of liposomes such as phosphatidylcholine to cholesterol ratio (PC:CH), PTX and stearylamine on entrapment efficiency (% EE) and particle size were systematically investigated and optimized using central composite design on Design-Expert®. The optimized liposomes were utilized as a template for silica coating to prepare surface coated PTX liposils.
