Cancer is class of diseases that has great diversity and unfortunately is one of the leading causes of death in the United States. Chemotherapy remains an important cancer treatment modality, and superior chemotherapeutic drugs are constantly being sought. Gemcitabine is an anti-tumor chemotherapeutic drug and it is the first line...
A computer program, SAW3DG, was developed to optimize log breakdown
using 3-dimensional log and internal defect shapes. The program was based on
SAW3D, a log breakdown optimization program considering only 3-dimensional log
shape. SAW3D was modified to include internal log defects in 3-dimensional
representation and integrated with SLGRADER, an expert...
This dissertation describes formulation of a gastric retention device (GRD) and sustained release (SR) hydrochlorothiazide beads at Oregon State University. Formulation condition and amounts of excipients had significant influence on characteristic of the GRD. The GRD containing SR hydrochlorothiazide beads was employed to assess bioavailability/bioequivalency study in healthy subjects. An...
Reproductive function in the dog is controlled by feedback mechanisms that involve the hypothalamus, the anterior pituitary gland, and the gonads. Surgical gonad removal, a common procedure performed in dogs for the purposes of sterilization, disrupts the hypothalamic-pituitary-gonadal (HPG) axis and results in permanently elevated concentrations of gonadotropins. Manipulation of...
This thesis describes in vitro and in vivo evaluation of a gastric retention formulation (GRF) developed at Oregon State University. The formulation was prepared from xanthan gum and locust bean gum as gelling agents and other formulation ingredients were added, then it was originally vacuum oven dried. The effect of...
At present all vaccines for fish are primarily delivered either by injection or immersion which introduces added stress and labor. A more attractive method of vaccine delivery is oral administration using an enteric protection system, Enteric Coated Antigen Microspheres (ECAMs), which can be utilized for a variety of antigenic forms....
Currently, the only anthrax vaccine licensed for human use in the United States is the Anthrax-vaccine-absorbed (AVA or Biothrax®). AVA suffers from several drawbacks, including a complicated and lengthy dosing schedule that requires six initial injections administered over eighteen months, followed by annual boosters. Therefore, a new generation anthrax vaccine...
Numerous studies have explored how alluvial channel size and morphology are adjusted to different sediment and flow conditions, yet we still know very little about how and to what degree the flow regime controls channel form and processes. We use the term ‘channel form’ to refer to the size and...
This research project focuses on the Walla Walla River Basin located on the east side of the states of Oregon and Washington, USA. With the support and collaboration of the Walla Walla Basin Watershed Council, this work embraces four research topics. The first topic includes the feasibility study of artificial...
