Consumption Of High Ω-3 Fatty Acid Diet Suppressed Prostate Tumorigenesis In C3(1) Tag Mice, Juliana Akinsete, Gabriela Ion, Theodore Witte, W. Hardman Oct 2012

Consumption Of High Ω-3 Fatty Acid Diet Suppressed Prostate Tumorigenesis In C3(1) Tag Mice, Juliana Akinsete, Gabriela Ion, Theodore Witte, W. Hardman

Gabriela Ion

Prostate cancer incidence and mortality are high in the Western world and high ω-6/ω-3 PUFA in the Western diet may be a contributing factor. We investigated whether changing from a diet that approximates ω-6 fat content of the Western diet to a high ω-3 fat diet at adulthood might reduce prostate cancer risk. Female SV 129 mice that had consumed a high ω-6 diet containing corn oil for 2 weeks were bred with homozygous C3(1)Tag transgenic male mice. All male offspring were weaned to the corn oil diet (CO) until postpuberty when half of the male offspring were transferred to …


Effects Of Diets High In Whey, Soy, Red Meat And Milk Protein On Body Weight Maintenance In Diet-Induced Obesity In Mice, Xu-Feng Huang, Y Liu, Gita Rahardjo, Peter Mclennan, Linda Tapsell, William Buttemer Sep 2012

Effects Of Diets High In Whey, Soy, Red Meat And Milk Protein On Body Weight Maintenance In Diet-Induced Obesity In Mice, Xu-Feng Huang, Y Liu, Gita Rahardjo, Peter Mclennan, Linda Tapsell, William Buttemer

This study examined the effects of different food sources of protein on energy intake, body weight maintenance, and on the responses of plasma leptin, insulin and adiponectin in chronic high-fat diet-induced obese mice. Obesity was induced in 47 mice with a high-fat diet for 20 weeks. They were divided into five diet groups to test the effects of a higher protein proportion (30% energy), achieved at the expense of carbohydrate. For the next eight weeks, four of the groups were fed diets of chow formulated with whey, soy, red meat or milk while the control group continued on their high-fat …


Adaptation To Hard-Object Feeding In Sea Otters And Hominins, Paul Constantino, James Lee, Dylan Morris, Peter Lucas, Adam Hartstone-Rose, Wah-Keat Lee, Nathaniel Dominy, Andrew Cunningham, Mark Wagner, Brian Lawn Sep 2012

Adaptation To Hard-Object Feeding In Sea Otters And Hominins, Paul Constantino, James Lee, Dylan Morris, Peter Lucas, Adam Hartstone-Rose, Wah-Keat Lee, Nathaniel Dominy, Andrew Cunningham, Mark Wagner, Brian Lawn

The large, bunodont postcanine teeth in living sea otters (Enhydra lutris) have been likened to those of certain fossil hominins, particularly the ’robust’ australopiths (genus Paranthropus). We examine this evolutionary convergence by conducting fracture experiments on extracted molar teeth of sea otters and modern humans (Homo sapiens) to determine how load-bearing capacity relates to tooth morphology and enamel material properties. In situ optical microscopy and x-ray imaging during simulated occlusal loading reveal the nature of the fracture patterns. Explicit fracture relations are used to analyze the data and to extrapolate the results from humans to earlier hominins. It is shown …


Microwear, Mechanics And The Feeding Adaptations Of Australopithecus Africanus, Paul Constantino, Craig Byron, Paul Dechow, Ian Gross, Peter Lucas, Brian Richmond, Callum Ross, Dennis Slice, Mark Spencer, Dennis Strait, Qian Wang, Gerhard Weber, Bernard Wood, Barth Wright Sep 2012

Microwear, Mechanics And The Feeding Adaptations Of Australopithecus Africanus, Paul Constantino, Craig Byron, Paul Dechow, Ian Gross, Peter Lucas, Brian Richmond, Callum Ross, Dennis Slice, Mark Spencer, Dennis Strait, Qian Wang, Gerhard Weber, Bernard Wood, Barth Wright

Recent studies of dental microwear and craniofacial mechanics have yielded contradictory interpretations regarding the feeding ecology and adaptations of Australopithecus africanus. As part of this debate, the methods used in the mechanical studies have been criticized. In particular, it has been claimed that finite element analysis has been poorly applied to this research question. This paper responds to some of these mechanical criticisms, highlights limitations of dental microwear analysis, and identifies avenues of future research.
