( Elsevier B.V. , 2020 , Article)Background: Microscopic patches as quite promising platforms in transdermal drug delivery suffer from conventional injections. In other hand, a wide range of pharmacokinetics, ranging from fast oral administration to ... -
Polymerization of 3-cyanopropyl (triethoxy) silane: A kinetic study using gas chromatography
( John Wiley and SonsInc. , 2018 , Article)Gas chromatography (GC) was used to study the kinetics of the 3-cyanopropyl triethoxysilane (CTES) polymerization. The reaction is a consecutive complex reaction that depends mainly on the kinetics of the first hydrolyzed ... -
Polymers to improve the world and lifestyle: physical, mechanical, and chemical needs
( Elsevier , 2020 , Book chapter)The wide-ranging applications of polymers are due to their important advantages that involve their relatively low cost, low density, resistance to corrosion, resistance to most chemicals, and easier manufacturing designs. ... -
The polymorphism at the microRNA-155 binding site in AGTR1 gene is not significantly associated with rheumatic heart disease in Saudi Arabia population
( Bentham Science Publishers , 2020 , Article)Rheumatic heart disease (RHD) remains a major cause of cardiovascular diseases and the most devastating effects are on children and young adults. RHD is caused due to the interaction between microbial, environmental, ... -
Polyolefin-Based Smart Self-Healing Composite Coatings Modified with Calcium Carbonate and Sodium Alginate.
( MDPI , 2024 , Article)Corrosion-related damage incurs significant capital costs in many industries. In this study, an anti-corrosive pigment was synthesized by modifying calcium carbonate with sodium alginate (SA), and smart self-healing coatings ... -
Polypharmacy and drug interactions amongst cirrhotic patients discharged from a tertiary center: Results from a national quality improvement audit
( Elsevier , 2020 , Article)Background and Study AimsAuditing of polypharmacy is particularly essential in patients with cirrhosis because of the crucial role of liver in drug metabolism. The aim of this study was to audit the drug prescribed in this ... -
Polypharmacy in the management of patients with schizophrenia on risperidone in a tertiary-care hospital in Malaysia
(2012 , Article)The present study was conducted primarily to determine the occurrence of polypharmacy in patients with schizophrenia on risperidone. The secondary aim was to ascertain the incidence of inappropriate prescribing with ... -
