Rosuvastatin (ROS), a statin drug with promising anticancer properties has a low bioavailability of approximately 20% due to lipophilicity and first-pass metabolism. This study aimed to enhance ROS anticancer efficacy through loading into flexible chitosomes. The chitosomes were prepared starting from negatively charged liposomes through electrostatic interactions with chitosan.

Background: Alzheimer's disease (AD) is one of the furthermost advanced neurodegenerative disorders resulting in cognitive and behavioral impairment. Citicoline sodium (CIT) boosts the brain's secretion of acetylcholine, which aids in membrane regeneration and repair. However, it suffers from poor blood-brain barrier (BBB) permeation, which results in lower levels of CIT in the brain.

Topical formulation of non-steroidal anti-inflammatory drugs (NSAIDs) exhibits many advantages over the oral administration route, such as avoiding the direct effect on GIT and avoiding the poor oral bioavailability of such drugs. Our study aims to develop a new self-assembling construct based on the hydrophobic interaction between adamantane terminated poly (ethylene glycol) polymers and polymerized β-cyclodextrin. The viscous constructs were developed from direct mixing of host and guest polymer solutions, indicating spontaneous formation without cross-linkers.

Background: SARS-COVID-2 has recently been one of the most life-threatening problems which urgently needs new therapeutic antiviral agents, especially those of herbal origin.

Purpose: The study aimed to load acaciin (ACA) into the new self-assembled nanofibers (NFs) followed by investigating their possible antiviral effect against bovine coronavirus (BCV) as a surrogate model for SARS-COV-2.

Methods: ACA was identified using H-NMR and DEPT-Q C-NMR spectroscopy, the molecular docking study was performed using Autodock 4 and a modification of the traditional solvent injection method was applied for the synthesis of the biodegradable NFs.

Epigallocatechin-3-gallate (EGCG) is a pleiotropic compound with anticancer, anti-inflammatory, and antioxidant properties. To enhance EGCG anticancer efficacy, it was loaded onto gold nanoparticles (GNPs). EGCG-GNPs were prepared by a simple green synthesis method and were evaluated using different techniques.

The aim of this study was to prepare triamcinolone acetonide (TA)-loaded poly(ethylene glycol)--poly(ε-caprolactone) (PEG--PCL) and poly(ethylene glycol)--poly(lactic acid) (PEG--PLA) micelles as a potential treatment of ocular inflammation. The micelles were evaluated for particle size, drug loading capacity and drug release kinetics. Selected micellar formulations were dispersed into chitosan hydrogel and their anti-inflammatory properties were tested in rabbits using a carrageenan-induced ocular inflammatory model.

Objectives: Transcranial magnetic stimulation (TMS) allows exploration of the mode of action of neuroactive substances in the human brain, and allows evaluation of neuronal networks, which might be involved in the action of nicotine. The aim of the present study was to explore motor cortex excitability in chronic smokers and non-smokers using TMS.

Methods: The study included 50 healthy subjects, of whom 25 were chronic smokers and 25 were age- and sex-matched non-smokers.

Hepatitis B virus (HBV) infection remains a public health problem worldwide. In this review, we aim to assess the current situation of the HBV care pathway in the Kingdom of Saudi Arabia (KSA), identify gaps/barriers therein, and recommend initiatives to be taken to improve the management of such patients. Towards this end, a literature search was conducted in PubMed and free Internet searches.

Fluorouracil (5-FU) is an antimetabolite drug used in the treatment of various malignancies, such as colon and skin cancers. However, its systemic administration results in severe side effects. Topical 5-FU delivery for the treatment of skin cancer could circumvent these shortcomings, but it is limited by the drug poor permeability through the skin.

Objective: To enhance 5-fluorouracil (5-FU) permeability through the skin by loading onto gold nanoparticles (GNPs) capped with two cationic ligands, benzalkonium chloride (BC) or poly (ethylene imine) (PEI). Whereas 5-FU has excellent efficacy against many cancers, its poor permeability through biological membranes and several adverse effects limit its clinical benefits. BC and PEI were selected to stabilize GNPs and to load 5-FU through ionic interactions.
