Establishing governing equations for 3D cell culture in perfusion bioreactors
(2014-05)
Culturing cells and regenerating tissues in vitro on 3D scaffolds involves several challenges, such as efficient nutrient transportation, uniform stress distribution, and the removal of wastes. Bioreactors not only allow ...
Hydrate formation in waxy oil systems
(2016-12)
Emulsions are of great importance due to their widespread occurrence in industries such as pharmaceutical, cosmetics, food, agricultural, and energy. In the energy industry, emulsions may be encountered in all stages of ...
Analysis of nitric oxide transfer and release rate for a cysteine modified polymer
(2010-05)
Scope and Method of Study: In order to improve the haemocompatibility of biomaterials so that platelet adhesion on the surface can be minimized, a cysteine (CySH) modified polymer was developed previously and preliminary ...
Effect of monocyte chemoattractant protein-1 concentration gradients on monocyte migration in a three-dimensional in vitro vascular tissue model
(2015-07)
The initiation of atherosclerosis is marked by the accumulation of lipid substances in the subendothelial layer of major arteries, followed by adhesion and transmigration of monocytes to the extracellular matrix (ECM). ...
Extrusion-based, three-dimensional printing of calcium-phosphate scaffolds
(2015-12)
Small or large bone defects, can occur due to a variety of reasons: congenital disorders, infections, tumors, or traumas which can lead to significant disabilities. There is an assortment of bone grafting procedures, each ...
