Stability Of The Miniscrew-Bone Interface: Reverse Torque Values In Rabbits, Daniel John Drye
Stability Of The Miniscrew-Bone Interface: Reverse Torque Values In Rabbits, Daniel John Drye
Loma Linda University Electronic Theses, Dissertations & Projects
Introduction: Miniscrews are used in orthodontics as practical temporary anchorage devices (TAD's). The purpose of this animal study was to measure reverse torque values for Absoanchor 1.2 mm and Micerium 1.5mm miniscrews at 0, 2, and 12 weeks under loaded and unloaded conditions.
Methods: Ninety-six miniscrews were placed in the femora of twelve rabbits and allowed to heal for either two or twelve weeks. Half of the fixtures were loaded immediately with NiTi open coil springs producing a force of 150-200g and the other half served as unloaded controls. For each of the healing times, two and twelve weeks, …
Mechanisms Of Hbo-Induced Neuroprotection In A Neonatal Hypoxia-Ischemia Model, John Winter Calvert
Mechanisms Of Hbo-Induced Neuroprotection In A Neonatal Hypoxia-Ischemia Model, John Winter Calvert
Loma Linda University Electronic Theses, Dissertations & Projects
With an incidence approaching 1/4000 live births and as high as 60% in low birth weight infants, cerebral hypoxia-ischemia during the perinatal period is the single most important cause of acute mortality and chronic disability in newborns. Herein, we tested the hypothesis that following a hypoxic-ischemic insult hyperbaric oxygen (HBO) treatment can restore high energy metabolite levels in the affected regions of the brain and through this increase in energy levels ameliorate the spread of cell death following the insult. We also investigated if an additional mechanism by which HBO affords its neuroprotection is by altering the expression of the …

Animal Models Of Head Trauma, Ibolja Cernak
Animal Models Of Head Trauma, Ibolja Cernak
Biomedicine and Animal Models in Research Collection
Animal models of traumatic brain injury (TBI) are used to elucidate primary and secondary sequelae underlying human head injury in an effort to identify potential neuroprotective therapies for developing and adult brains. The choice of experimental model depends upon both the research goal and underlying objectives. The intrinsic ability to study injuryinduced changes in behavior, physiology, metabolism, the blood/tissue interface, the blood brain barrier, and/or inflammatory- and immune-mediated responses, makes in vivo TBI models essential for neurotrauma research. Whereas human TBI is a highly complex multifactorial disorder, animal trauma models tend to replicate only single factors involved in the pathobiology …
Histological Comparison Of White And Gray Mta In Repair Of Furcation Perforations, Miguel Elias Mego
Histological Comparison Of White And Gray Mta In Repair Of Furcation Perforations, Miguel Elias Mego
Loma Linda University Electronic Theses, Dissertations & Projects
Mineral trioxide aggregate (MTA) has been shown to promote regeneration of the periodontal apparatus when used as a repair material in furcation perforations. Two variations of MTA (Gray and White) have been introduced to the dental market. The purpose of this study was to histologically compare the in vivo response to immediate furcation perforation repair using gray or white MTA in beagle dogs.
Under general anesthesia, non-surgical root canal therapy and furcal perforations were performed on sixteen mandibular premolars of eight 2-year old beagle dogs. The perforations were immediately repaired with either white (n=8) or gray (n=8) MTA. The animals …

Non-Human Primates In Medical Research And Drug Development: A Critical Review, Jarrod Bailey
Non-Human Primates In Medical Research And Drug Development: A Critical Review, Jarrod Bailey
Laboratory Experiments Collection
There is much current debate surrounding the use of non-human primates (NHPs) in medical research and drug development. This review, stimulated by calls for evidence from UK-based inquiries into NHP research, takes a critical view in order to provide some important balance against papers supporting NHP research and calling for it to be expanded. We show that there is a paucity of evidence to demonstrate the positive contribution or successful translation of NHP research to human medicine, that there is a great deal of often overlooked data showing NHP research to be irrelevant, unnecessary, even hazardous to human health and …
Chimpanzees In Research: Past, Present, And Future, Kathleen Conlee, Sarah T. Boysen
Chimpanzees In Research: Past, Present, And Future, Kathleen Conlee, Sarah T. Boysen
State of the Animals 2005
Although the welfare of chimpanzees encompasses many issues, this chapter addresses their use in research, including their historical and current use in the United States, ethical and scientific concerns, public opinion, international legislation, and future directions.
