Hydrogels have been proposed as candidates for nucleus pulposus replacement due to
their similarity in mechanical behavior to the native tissue when subjected to transient or
static loading; however, given the viscoelastic nature of soft biological tissues, the lack of
dynamic testing is a significant inadequacy in the studies performed...
A large part of low-back pain occurrences are due to disc herniation or prolapse of the nucleus pulposus. An alternative technique to existing treatments of low back pain includes nucleus pulposus replacement by an artificial material to relieve pain and restore normal function. To date, there has been a deficiency...
Recent scientific studies show strong correlations between oral and systemic disease, creating a crucial need for increased collaboration between the medical and dental professions. Interdisciplinary collaboration between medical and dental providers is emerging as a critical component to effective patient care. The role of the dental hygienist in interdisciplinary collaboration...
This thesis examines how changes made to the Oregon Health Plan (OHP) in 2003 impacts those now utilizing the emergency room (ER) for primary health care. This thesis also examines how these changes impact staff members working in the ER of Salem Hospital. Through the utilization of qualitative research methods,...
Thousands of children and adults suffer from fine motor skill deficits due to developmental disabilities or brain trauma. In order to acquire or reclaim these precision motor movements, occupational therapists work closely with each patient to develop the muscle memory required for completing tasks such as handwriting or drawing. Although...
The extent to which thermoacoustic data determines the acoustic properties of an object was studied. In the case of one dimensional thermoacoustic imaging it was shown that constant acoustic profiles are uniquely specified from measurements. For a radial thermoacoustic problem we have shown that if the acoustic source is radial...
The disposition of four therapeutically important antimicrobial agents was studied in llamas following intravenous bolus administration. Six llamas were each given ampicillin, tobramycin, trimethoprim and enrofloxacin at a dose of 12 mg/kg, 1 mg/kg, 3 mg/kg and 5 mg/kg of body weight with a wash out period of 3 days...
A series of TiNbHf alloys ranging from 0-40 atomic %
Nb and 0-15 atomic % Hf were evaluated to investigate
low-elastic modulus phenomena which occur in this ternary
system. The desirability of utilizing corrosion-resistant, biocompatible alloys with elastic modulus values
approaching that of human bone for medical prosthetic
implants provides...
Gastric retention time of single unit dosage forms in swine was found
to be much longer than in humans. It was concluded that swine are not a
good animal model to study GI transit time of nonerodable or slowly eroded
dosage forms. Noneradable and slowly eroded dosage forms used to...
Use of the Internet for health information has been gaining popularity, and some studies suggest an increase in the use of online interactive peer-to-peer forums for seeking health information. Internet health information-seeking is especially popular among those with stigmatized conditions such as obesity, and negative healthcare experiences have been linked...
