Theses, Dissertations and Capstones
The goal of this study is to examine the effect of urbanization and latitude on bone morphology, specifically limb length and bone density among gray squirrels endemic to the eastern United States. This study’s hypotheses are as follows: gray squirrels occupying lower latitudes will have larger body sizes and longer limbs relative to body size than those at higher latitudes following Bergmann’s and Allen’s rules. Further, squirrels in urban habitats will have greater bone density than those in rural habitats. Results show moderate correlation between body mass and respective proxies and latitude following Bergmann’s rule. Weak correlations were found between …
The Effects Of Zoledronate And Sleep Deprivation On The Distal Femur Trabecular Thickness Of Ovariectomized Rats: Application Of Different Statistical Methods, Erin Nolte
Student Scholar Symposium Abstracts and Posters
Osteoporosis is a disease that causes the degradation of bone, leading to an increased risk of fracture. 1 in 3 women over the age of 50 will be affected by Osteoporosis. This study aims to understand how bone is affected by sleep deprivation in estrogen-deficient rats, and how Zoledronate might negate the inimical effects of sleep deprivation on bone. As bone mineral density (BMD) is a crude evaluation of the architectural changes seen in Osteoporosis, trabecular thickness may serve as a better single evaluation of bone health. 31 Wistar female rats were ovariectomized and separated into 4 random groups. The …
The Biological Significance And Utility Of Feeding By Dermestes Maculatus, Braymond Adams
The Biological Significance And Utility Of Feeding By Dermestes Maculatus, Braymond Adams
School of Natural Resources: Dissertations, Theses, and Student Research
With their efficient feeding habits and tolerance to very low moisture and humidity, beetles in the Family Dermestidae are especially adapted to variable environments and habitats. Dermestid cultures have been in use since 1922 in cleaning tissue and flesh from bones, and proven benefit in multiple fields, including zoology, ornithology, and forensics. Dermestid feeding behaviors when coupled with known life stage and insect succession information aids in providing significant entomological evidence. However, the feeding activities of insects, like those of vertebrate scavengers and predators, change remains and may leave artifacts that can be sometimes be difficult to assign to a …
A Natural, Calcium-Rich Marine Multi-Material Complex Preserves Bone Structure, Composition And Strength In An Ovariectomized Rat Model Of Osteoporosis, Orlaith Brennan, Joseph Sweeney, Brian O'Meara, Amro Widaa, Franck Bonnier, Hugh Byrne, Denis O'Gorman, Fergal O'Brien

Calcium supplements are used as an aid in the prevention of osteopenia and osteoporosis and also for the treatment of patients when used along with medication. Many of these supplements are calcium carbonate based. This study compared a calcium-rich, marine multi-mineral complex (Aquamin) to calcium carbonate in an ovariectomised rat model of osteoporosis in order to assess Aquamin’s efficacy in preventing the onset of bone loss. Animals were randomly assigned to either non-ovariectomy control (Control), ovariectomy (OVX) plus calcium carbonate, ovariectomy plus Aquamin or ovariectomy plus Aquamin delay where Aquamin treatment started 8 weeks post OVX. At the end of …
An Investigation Of Alkaline Earth And Rare Earth Elements In Human Bone Following Long-Term Parenteral Nutrition, Aubrey L. Galusha
An Investigation Of Alkaline Earth And Rare Earth Elements In Human Bone Following Long-Term Parenteral Nutrition, Aubrey L. Galusha
Legacy Theses & Dissertations (2009 - 2024)
This investigation focused on a unique collection of archived human bones obtained post-mortem from 7 patients, who had received long-term parenteral nutrition (PN) for up to 21 years. Parenterals are administered intravenously as a nutritional supplement, and may be contaminated with metals, which are completely absorbed into the blood compartment. Some metal contaminants may be deposited in the body’s reservoir for inorganic elements – bone.
The Role Of Hydroxyl Channel In Defining Selected Physicochemical Peculiarities Exhibited By Hydroxyapatite, Vuk Uskoković
The Role Of Hydroxyl Channel In Defining Selected Physicochemical Peculiarities Exhibited By Hydroxyapatite, Vuk Uskoković
Pharmacy Faculty Articles and Research
Mysteries surrounding the most important mineral for the vertebrate biology, hydroxyapatite, are many. Perhaps the Greek root of its name, απαταo, meaning ‘to deceive’ and given to its mineral form by the early gem collectors who confused it with more precious stones, is still applicable today, though in a different connotation, descriptive of a number of physicochemical peculiarities exhibited by it. Comparable to water as the epitome of peculiarities in the realm of liquids, hydroxyapatite can serve as a paradigm for peculiarities in the world of solids. Ten of the peculiar properties of hydroxyapatite are sketched in this review piece, …
The Fish Bone Remains, Geoffrey Clark, Katherine Szabo
The Fish Bone Remains, Geoffrey Clark, Katherine Szabo
Katherine A Szabo
Fisheries are a fundamental part of Remote Oceanic economies and lifeways, used for different types of fishing, invertebrate capture and collection, and the gathering of marine plants. Where no bones or calcareous parts remain, these activities are invisible to archaeologists, but modern studies of marine exploitation in Fiji and elsewhere in the Pacific (e.g. Rawlinson et al. 1994; Dalzell et al. 1996) indicate that a good portion of activities should leave traces in the archaeological record. As with marine mollusca, tropical Indo-Pacific fish species diversity is high. However unlike the mollusca, our inability to identifY remains beyond the family level …
