This chapter surveys some recent work on the application of techniques from computational geometry to geometric problems arising in manufacturing processes such as layered manufacturing, mold design, and numerically controlled machining. Within each topic, we discuss problems that have benefited from the application of geometric techniques, and mention several other problems where such techniqu...
The objectives of this study were to determine the selection potential (genetic variation) of sow efficiency traits (prolificacy, longevity), to understand the co-responses (genetic correlations) among sow efficiency traits and other economically important traits (performance, carcass quality, and meat quality), and determine the feasibility of developing breeding value estimates for sow effici...
We developed a method, named GraFix, that considerably improves sample quality for structure determination by singleparticle electron cryomicroscopy (cryo-EM). GraFix uses a glycerol gradient centrifugation step in which the complexes are centrifuged into an increasing concentration of a chemical fixation reagent to prevent aggregation and to stabilize individual macromolecules. The method can ...
Current findings suggest a role for the angiotensin II (Ang II) signalling pathway in generation of reactive oxygen species and diabetes-induced cardiac complications. In this study we aimed to investigate the effect of angiotensin II type 1 (AT 1 ) receptor blockage on some antioxidant enzy mes such as glucose-6-phosphate dehydrogenase (G6PD), 6-phoshogluconate dehydrogenase (6PGD), glutathion...
Meal machine, experimental laboratory, status symbol, domestic prison, or the creative and spiritual heart of the home? Over the course of the past century no other room has been the focus of such intensive aesthetic and technological innovation, or as loaded with cultural significance. Kitchen design has been both a central concern of modernism and fundamental to our concept of modern life (Mo...
IN RECENT YEARS, THERE HAS BEEN A RAPID AND SIGNIFICANT PROGRESS IN UNDERSTANDING THE MOLECULAR BASIS OF THE CIRCADIAN RHYTHMICITY, AS SEVERAL CLOCK GENES HAVE BEEN CLONED IN MAMMALS. Studies with these genes focusing on loss of function have demonstrated abnormal sleep/wake length periods, disturbed entrainment, and loss of persistence of circadian rhythms. Current findings clearly indicate th...
introduction: over expression of selected peptide receptors in human tumors has been shown to represent clinically relevant targets for cancer diagnosis and therapy. the aim of this work was to investigate neuropeptide y (npy) as a new radiopharmaceutical for diagnosis of breast cancer. methods: a neuropeptide y analogues with y1 receptor preference and agonistic properties was synthesized by s...
objective: in this study we introduced an rgd-containing peptide of collagen iv origin that possesses potent cell adhesion and proliferation properties. this peptide was immobilized on a nanofibrous polycaprolactone/gelatin scaffold after which we analyzed human bone marrow-derived mesenchymal stem cells (hbmscs) adhesion and proliferation on this peptide-modified scaffold. methods: nanofibrous...
