Post-menopausal osteoporosis as a consequence of estrogen depletion is a growing concern for women in the United States. As more women take on executive positions and experience sleep deprivation, there is the potential for up regulation of pro-inflammatory cytokines, such as tumor necrosis factor alpha. It follows that the homeostatic imbalance of osteoclastic and osteoblastic activity leads to a greater risk of disease. Bisphosphonates generally, and Zolendronate specifically works by decreasing the number of osteoclasts. This current study investigated the impact of Zolendronate on the concentrations of tumor necrosis factor alpha-type (TNFɑ) in 32 ovariectomized Wistar rats. Throughout a five …


Bone Strength And Distal Femur Trabecular Thickness In Sleep Deprived Ovariectomized Rats Treated With Zoledronate, Erin Nolte, Frank Frisch Dec 2019

Bone Strength And Distal Femur Trabecular Thickness In Sleep Deprived Ovariectomized Rats Treated With Zoledronate, Erin Nolte, Frank Frisch

Student Scholar Symposium Abstracts and Posters

Osteoporosis is a disease that causes the density and quality of bone to be decreased, which can increase the risk of fracture by 40%. 1 in 3 women over the age of 50 will be affected by osteoporosis. This study aimed to show how bone strength and distal femur trabecular thickness might be affected by Zoledronate and sleep-deprivation in estrogen-deficient rats. Wistar female rats were ovariectomized to contrive postmenopausal estrogen-deficiency. The rats were separated into 4 groups. The control group (C, n=4) was given an intraperitoneal (IP) injection of 0.45 mL of 0.9% saline, were housed in standard conditions permitting …


The Impact Of A 20% Vs. A 40% Caloric Restrictive Diet On Bone Mineral Density During The Growth Period In Male Rats, Kassandra Lee May 2015

The Impact Of A 20% Vs. A 40% Caloric Restrictive Diet On Bone Mineral Density During The Growth Period In Male Rats, Kassandra Lee

Student Scholar Symposium Abstracts and Posters

Purpose: The purpose of this study was to determine the impact of a 20% and a 40% caloric restrictive diet on bone mineral density (BMD) and bone strength in male rats during the growth period. Methods: 32 male rats were randomly divided into: control groups (C20, n=8 and C40, n=8), a group fed the 20% caloric restrictive diet (D20, n=8), and a group fed the 40% caloric restrictive diet (D40, n=8). An animal in the caloric restrictive diet group was matched and pair fed with an animal in the control group for 6 weeks. Each caloric restrictive diet contained additional …


The Effects Of A Caloric Restrictive Diet On Bone Mineral Density And Bone Strength In Male And Female Rats, Haley Folta May 2015

The Effects Of A Caloric Restrictive Diet On Bone Mineral Density And Bone Strength In Male And Female Rats, Haley Folta

Student Scholar Symposium Abstracts and Posters

The purpose of this study was to determine the existence of sex differences following a 40% caloric restrictive diet and its impact on tibial bone mineral density (BMD) and bone strength between male and female rats. Thirty-two, six-week old Sprague Dawley rats (16 males and 16 females) were randomly divided into an ad libitum fed control group (MC, n=8 and FC, n=8) and a pair fed diet group placed on the 40% caloric restriction (MD, n=8 and FD, n=8) for a 6 week period. The caloric restrictive diet was equivalent to the normal fed diet in vitamin and mineral content …


Effects Of Human Recreational Activity On The Tameness Of Common Loons (Gavia Immer) In Northern Wisconsin, Seth Yund May 2015

Effects Of Human Recreational Activity On The Tameness Of Common Loons (Gavia Immer) In Northern Wisconsin, Seth Yund

Student Scholar Symposium Abstracts and Posters

The Common Loon (Gavia immer) is an aquatic diving bird that lives in freshwater habitats in Canada and the northern U.S.. Human activity on a loon’s resident lake may affect its fitness and behavior, yet few studies identify or quantify these effects. We modified existing techniques that measure escape distances in other species to measure tameness as the distance at which individual loons dove in response to human approach by canoe. Tameness was similar between pair members, suggesting that common lake conditions or the behavior of a mate might influence the behavior. Sex, size within sex, and human activity did …
