Microvascular strategies for damage restoration
… demonstrated by the incorporation of biomimetic microvascular networks within structural polymers and polymer composites. Internal networks of channels act as pathways for mass transport of liquid healing agents to damage regions that intersect the vasculature. Microvascular self-healing has …

Microvascular inflammatory response in the skin
This thesis examines the microvascular inflammatory response in the skin. The microvascular response includes vasodilatation and plasma exudation. In the first three studies, the combined response was measured in guinea pig skin with a technique based on detection of radiolabelled protein. …

Computational Design of Microvascular Biomimetic Materials
In this work, we propose to design these materials using Genetic Algorithms (GAs), the most common methodology within a broader category of Evolutionary Algorithms (EAs). GAs can be combined with a Pareto-selection mechanism to create Multi-Objective Genetic Algorithms (MOGAs), which enable the …

Computational design of microvascular biomimetic materials
Biomimetic microvascular materials are increasingly considered for a variety of autonomic healing, cooling and sensing applications. The microvascular material of interest in this work consists of a network of hollow microchannels, with diameters as small as 10 μm, embedded in a polymeric matrix. …

Direct ink writing of microvascular networks
Nature is replete with examples of embedded microvascular systems that enable efficient fluid flow and distribution for autonomic healing, cooling, and energy harvesting. The ability to incorporate microvascular networks in functional materials systems is therefore both scientifically and …

Microviscometric Analysis of Microvascular Hemodynamics in Vivo
… with an accuracy and detail unprecedented in microvascular research. Microviscometry depends only upon knowledge of the velocity profile over the cross section of a microvessel, which can readily be extracted using fluorescent micro-particle image velocimetry (mu-PIV) from distributions in the …

Microvascular Networks for Continuous Self -Healing Materials
… events in a continuous self-healing coating on a microvascular substrate. A three-dimensional, interconnected microvascular network in the substrate serves as a delivery system for healing materials to heal damage in a polymer coating. Two approaches to microvascular delivery are explored: one …

Directed Assembly of Three-Dimensional Microvascular Networks
The construction of 3-D microvascular networks enables microfluidic devices with unparallel geometric complexity. In one example, a 3-D microfluidic mixing device was demonstrated with square-spiral mixing towers isolated within the vascular network by a secondary photopatterning process. These …

Mechanisms of increased microvascular permeability during acute Rickettsiosis
… typhus. Rickettsiae primarily target the microvascular endothelium leading to increased microvascular permeability, the mechanisms of which are completely unknown. We sought to determine the impact of host responses to infection on increasing microvascular permeability both in vitro and in …

Genetic contribution to type 1 diabetes microvascular complications
… protect them from, the expression of the chronic microvascular complications: retinopathy, neuropathy and nephropathy. In my first chapter, I introduce the history of type 1 diabetes and microvascular complications and their importance as a public health concern. Data show that the prevalence for …

Microvascular oxygen transport: development of an optical triplicator
Microvascular oxygen transport has been studied using many experimental methods. The three wavelength photometric method of Pittman and Duling (6) was the basis for this project. An optical triplicator was introduced into the microscopy assembly. The triplicator’s function was to take the image …

Nonlinear Dynamical Analysis Of Microvascular Red Blood Cell Flow
Microvascular red blood cell (RBC) flow is an enormously complex and dynamically variable process. Variations appear as temporal fluctuations within vessels, and spatially, along or between vessels in a network. These variations occur on many different time scales and highlight microcirculatory …

Nonlinear dynamics of blood flow in simple microvascular networks
… hematocrit, and blood velocity can occur in microvascular networks in the absence of biological control. In this paper, both analytical and numerical methods have been used to investigate the nonlinear dynamics of microvascular blood flow in simple networks. First, the steady state solutions …
