Investigations of gluten proteins from functional and historical perspective

Creator:: Zhang, Ying
Abstract:: Wheat (Triticum aestivum) is one of the world’s major staple food crops, with flour produced from starchy endosperm being used for breads, cakes, noodles and various other wheat-based foods. The unique bread making properties of wheat are primarily attributed to its gluten-forming storage proteins: gliadins and glutenins. This study investigated...

The role of leptin in normal and pathological bone resorption

Creator:: Philbrick, Kenneth Alan
Abstract:: Particles generated from wear of prosthesis joint bearing surfaces induce inflammation and promote pathological periprosthetic osteoclast-mediated bone resorption (osteolysis). Obesity increases the risk of prosthesis failure. However, despite being morbidly obese, leptin-deficient ob/ob mice are resistant to osteolysis. These findings suggest that leptin exerts effects that act to increase particle-induced...
