Swimming Versus Voluntary Running Exercise On Bone Health In Ovariectomized Retired Breeder Rats, Shelly Ann Duhe
Swimming Versus Voluntary Running Exercise On Bone Health In Ovariectomized Retired Breeder Rats, Shelly Ann Duhe
LSU Master's Theses
Physical activity may increase long bone calcium (Ca) content to preserve bone strength in postmenopausal women. This study determined the effect of compulsory swimming and voluntary running exercise on bone mineral density, bone Ca and phosphorus (P) content, and femoral neck and tibia strength in ovariectomized (OVX) retired breeder rats, as a model for postmenopausal women. Thirty-seven nine-month old Sprague Dawley rats were assigned randomly into one of four treatment groups for the nine-week study: OVX + running (OR; n=9); OVX + swimming (OS; n=10); OVX + no exercise (O; n=9); sham-surgery + no exercise (Sh; n=9). OR rats had …
Using Trabecular Architecture Of The Proximal Femur To Determine Age At Death: An Accuracy Test Of Two Methods, Wendy Michelle Jones
Using Trabecular Architecture Of The Proximal Femur To Determine Age At Death: An Accuracy Test Of Two Methods, Wendy Michelle Jones
LSU Master's Theses
Osteologists and forensic researchers are often called upon to determine age at death for skeletal remains. Although there are common methods in wide use, new methods are always sought. This study evaluates the accuracy of two radiographic methods of determining age by looking at the changes in the trabecular architecture of the proximal femur. These two methods are the Szilvassy and Kritscher (1990) method and the Walker and Lovejoy (1985) method. Samples were taken from four skeletal collections. Radiographs were taken of each individual and both Szilvassy and Kritscher’s (1990) phases of trabecular change and Walker and Lovejoy’s (1985) phases …
