(Texas A&M University, 2001)Pilots routinely utilize positive pressure breathing to prevent hypoxia while flying at high altitudes. In addition, positive pressure breathing is also exploited to avoid syncope while pilots experience elevated Gz levels. ...
-
(Texas A&M University, 1999)Visualization of scientific data plays an ever increasingly vital role in the study of humans, plants, animals, and the world around us. An integral part of that visualization and what makes it possible is the use of ...
-
The application of surface-enhanced Raman spectroscopy for the detection of excitatory amino acids (Texas A&M University, 1999)The release of excitatory amino acids (EAAs) from injured neurons has been associated with secondary injury following head trauma. The development of a rapid and sensitive method for the quantification of EAAs may provide ...
-
(Texas A&M University, 2002)Subarachnoid hemorrhage following the rupture of a cerebral aneurysm is one of the most devastating neurological catastrophes affecting adults. It has been well documented that cerebral aneurysms frequently form at arterial ...
-
(Texas A&M University, 2002)Data on the mechanical properties of the lens capsule available in the literature are limited, providing only global and 1-D information. There has yet to be any systematic, rigorous study of the nonlinear multiaxial ...
-
(Texas A&M University, 2001)Intracranial saccular aneurysms present a very challenging problem both clinically and for the bioengineer. As long as a complete understanding of their material properties is unavailable, other ways to gain insight into ...
-
(Texas A&M University, 2004)Constitutive modeling of soft tissue has provided better understanding of their function and behavior in both normal and pathophysiological conditions. The ability to predict growth and remodeling of the tissue under the ...
-
(Texas A&M University, 2000)The aim of this project was the qualitative and quantitative characterization of the variations in the corneal birefringence in the rabbit eye through the design and development of an automated optical setup. The results ...
-
(Texas A&M University, 2002)In humans and rats, microgravity induces adaptations within the cardiovascular system that appear to include modifications in peripheral vascular reactivity. Rodent hindlimb unweighting (HU) has been used to model putative ...
-
(Texas A&M University, 2002)Previous studies have indicated that optical means of blood glucose detection are feasible and provide a minimally invasive alternative to current commercially available modalities. Fluorescence spectroscopy has shown ...
-
(Texas A&M University, 1999)Regulation of contractile activity in cardiac muscle is a cooperative interaction between thick and thin filament sarcomeric proteins. Tropomyosin (Tm), an essential thin filament protein, interacts with troponin (Tn) and ...
-
(Texas A&M University, 2003)Mechanical forces such as shear stress and pressure affect the cells of the arterial wall. Large arteries seek to maintain an optimal shear stress of 1.5 Pa and a circumferential stress of 100 kPa; when conditions such ...
-
(Texas A&M University, 1998)An analog cum digital computing hybrid system is analyzed, to compare its speed of computation and accuracy with a full digital computer, for quantum chemical molecular modeling. This is done at the level of the simulation ...
-
(Texas A&M University, 1999)Cerebral saccular aneurysms are likely harbored by 3 to 5% of the population of the United States. Rupture of cerebral aneurysms is the leading cause of spontaneous subarachnoid hemorrhage, which claims 35 to 50% of its ...
-
(Texas A&M University, 1998)A three-dimensional computer graphic simulation which hics. allows for the arbitrary placement of axes of motion with respect to skeletal structures is described. The simulation, developed on a Sum UItraSPARC high performance ...
-
(Texas A&M University, 1998)A system was developed using a Fourier Transform-n spectrometer to investigate spectral differences between malignant, benign and healthy oral tissue in the near-infrared range (2.0-2.5 microns). A hamster model for oral ...
-
(Texas A&M University, 1999)Current techniques used to monitor glucose concentration of cell culture media require invasive and tedious handling of the sample for sterile media removal and nutrient replacement. In order to maximize cell culture growth ...
-
(Texas A&M University, 2003)The isolated perfused working heart preparation has been an established method of investigation for larger animals. However, because of technical, economic and ethical issues, this methodology needs to be extended for use ...
-
(Texas A&M University, 2000)During embryonic development, the heart undergoes remarkable morphological changes due to genetic programming and epigenetic influences such as mechanical loads. L.A. Taber and colleagues at Washington University have ...
-
(Texas A&M University, 2000)Six bone slices from one canine tibia were tested by compressive load to determine the ultimate strength as a function of distance from the knee. Both the ultimate compressive strength and overall modulus of elasticity of ...
