Characterization Of An Antiviral Agent Based On Nonionic Surfactants And It's Effects On Human Dermal Fibroblasts, Ji Young Li Oct 1994

Characterization Of An Antiviral Agent Based On Nonionic Surfactants And It's Effects On Human Dermal Fibroblasts, Ji Young Li

Biological Sciences Theses & Dissertations

The AIDS ·pandemic has directed various research endeavors towards finding an appropriate method for eliminating all potentially infectious material within bone allografts before implantation into a recipient. To that effect, Panavirocide was conceived by Medicine and Applied Science·s, Inc. This compound, in which three nonionic surfactants serve as the active agents, has been shown to inactivate HIV-1 particles within blood and blood products. Because Panavirocide has never been used with allografts, the purpose of the present research was to characterize the nonionic surfactants for the putative alteration of the formulation by determining the critical micelle concentration values and to determine …

Periodontal Repair In Dogs : Part I : Evaluation Of The Natural Disease Model ; Part Ii : Eptfe Barrier Membranes Support Wound Stabilization And Enhance Bone Regeneration, James Marc Haney Jun 1994

Periodontal Repair In Dogs : Part I : Evaluation Of The Natural Disease Model ; Part Ii : Eptfe Barrier Membranes Support Wound Stabilization And Enhance Bone Regeneration, James Marc Haney

Loma Linda University Electronic Theses, Dissertations & Projects

Animal models are frequently consulted for histometric analysis of reconstructive periodontal therapy. Statistical analysis of induced lesion defects and surgically created defects from our laboratory suggest defect size homogeneity is critical for the model to discriminate treatment effects. This study characterizes natural disease defects in beagle dogs. Buccal-lingual histologic sections from the 2nd, 3rd, and 4th mandibular premolar teeth (P2, P3, P4) from 6 aged beagle dogs with natural disease defects were evaluated for variation in defect height between pair matched tooth types, and jaw quadrants, as well as estimated confidence intervals for treatment differences between left and right pair …


Investigation Of Selenium Status In Hypo-, Hyper- And Euthyroid Children, Ping Sun Apr 1994

Investigation Of Selenium Status In Hypo-, Hyper- And Euthyroid Children, Ping Sun

Chemistry & Biochemistry Theses & Dissertations

Recently, it has been reported that human type I iodothyronine deiodinase, an enzyme important in the conversion of T4 to T3 , is a selenoenzyme. Several studies have reported alterations in plasma selenium level in hypo- and hyperthyroid patients.

Using polarized Zeeman-effect atomic absorption spectroscopy, we measured selenium, zinc, copper and manganese concentrations in the plasma and/or red blood cells in children with or without thyroid disease being seen at the outpatient clinic at Children's Hospital of the King's Daughters. Children with thyroid disease were subdivided into untreated, treated and nonresponsive groups. Data were analyzed using Student's t-test …


The Amino-Terminal Functions Of The Simian Virus 40 Large T Antigen Are Required To Overcome Wild-Type P53-Mediated Growth Arrest Of Cells., Robin S. Quartin, Charles N. Cole, James M. Pipas, Arnold J. Levine Mar 1994

The Amino-Terminal Functions Of The Simian Virus 40 Large T Antigen Are Required To Overcome Wild-Type P53-Mediated Growth Arrest Of Cells., Robin S. Quartin, Charles N. Cole, James M. Pipas, Arnold J. Levine

Dartmouth Scholarship

High levels of the p53 tumor suppressor protein can block progression through the cell cycle. A model system for the study of the mechanism of action of wild-type p53 is a cell line (T64-7B) derived from rat embryo fibroblasts transformed by activated ras and a temperature-sensitive murine p53 gene. At 37 to 39 degrees C, the murine p53 protein is in a mutant conformation and the cells actively divide, whereas at 32 degrees C, the protein has a wild-type conformation and the cells arrest in the G1 phase of the cell cycle. Wild-type simian virus 40 large T antigen and …


Coping With The Risk Of Cancer In Children Living Near Power Lines, Eileen N. Abt Jan 1994

Coping With The Risk Of Cancer In Children Living Near Power Lines, Eileen N. Abt

RISK: Health, Safety & Environment (1990-2002)

Ms. Abt briefly summarizes evidence linking power lines with a possible increase in risk of childhood cancer. She also recounts how, although many experts remain skeptical of causality, public fears, whether or not warranted, have themselves created serious problems. Finally, she proposes ways to address those problems.

In Vitro And In Vivo Effects Of Chemotherapeutants On The Oyster Parasite, Perkinsus Marinus, Gustavo W. Calvo Jan 1994

In Vitro And In Vivo Effects Of Chemotherapeutants On The Oyster Parasite, Perkinsus Marinus, Gustavo W. Calvo

Dissertations, Theses, and Masters Projects

To investigate the potential of chemotherapeutants to control the oyster pathogen Perkinsus marinus, anticoccidial and antifungal compounds were tested in vitro on infected hemolymph and cultured P. marinus cells and in vivo on infected oysters. In addition, acute toxicity to oysters was determined for six anticoccidials. In vitro experiments with infected hemolymph consisted of 24 h exposure of 0.2 mL hemolymph aliquots to concentrations ranging from 100 mg/L to 0.01 mg/L of amphotericin-B, amprolium, arprinocid, cycloheximide, lasalocid, malachite green, monensin, sulfadimethoxine, and a potentiated sulfadimethoxine, followed by incubation in fluid thioglycollate medium (FTM) to determine prezoosporangia abundance. Lasalocid, malachite green, …

Quality Wool Production At Lower Cost, Peter Metcalfe Jan 1994

Quality Wool Production At Lower Cost, Peter Metcalfe

Journal of the Department of Agriculture, Western Australia, Series 4

Low wool prices are forcing farmers to reduce their sheep management costs but, fortunately, cost cutting is not resulting in lower wool production, poorer wool quality or lessened sheep care on the best wool growing properties.
