The mineral density and atomic numbers of elements in the periosteal callus and the cortex area of a healing fracture were measured by quantitative computerized tomography (QCT) to obtain accurate information on the mineralization process in rabbit tibia. The mineral density of the periosteal callus was highest on day 15 and decreased gradually throughout the experiment. This was initially detected by QCT, but not with conventional radiography. An apparent decrease in cortical bone density on days 28 and 42 after fracture was observed. Atomic numbers of elements in the cortex remained stable, indicating a possible homeostatic mechanism of mineral preservation at the fracture callus and involved cortical area. QCT may predict density alterations in the fracture callus more accurately than conventional X-ray. Further studies are essential to predict a relationship between mineral density, atomic numbers, and mechanical stability.

Vibration analysis of the human radius of elderly men Oezdurak, R. Huerrem; Sezgin, Oender C.; Akın, Serhat; Korkusuz, Feza (Ovid Technologies (Wolters Kluwer Health), 2006-02-01) Vibration analysis seldom has been used in detecting structural and mechanical changes in physiologic and pathologic bone conditions. We sought to correlate natural frequency of the radius measured by vibration analyses with bone mineral density measured by dual-energy xray absorptiometry and quantitative computed tomography (including cortical thickness). Sixty sedentary men between 50 and 70 years old were deemed osteopenic or healthy. A higher natural frequency of the dominant and nondominant radius was ...
Determination of Zinc, Copper, Iron, and Manganese in Different Regions of Lamb Brain Bakirdere, Sezgin; Kizilkan, Nese; YAMAN, MEHMET (Springer Science and Business Media LLC, 2011-09-01) The levels of zinc, copper, iron, and manganese were measured in the hippocampus, thalamus, gyrus cinguli, hypothalamus, and in the prefrontal, parietal, temporal, and occipital cortexes of lamb brain by flame atomic absorption spectrometry. Standard addition method was also applied to samples and it was observed that there was no matrix interference affecting the determination of elements interested. In the determination of Cu, a slotted tube atom trap was used to improve sensitivity. One-way analysis of v...
Vibration measurements predict the mechanical properties of human tibia Bediz, Bekir; Özgüven, Hasan Nevzat; Korkusuz, Feza (Elsevier BV, 2010-05-01) Background: Vibration analysis is a promising technique in diagnosing metabolic bone diseases such as osteoporosis and monitoring fracture healing. The aim of this study is to observe the structural dynamic property changes of the tibia extracted from the vibration analysis data.
Surgical repair of cartilage defects of the patella Atik, OS; Korkusuz, Feza (Ovid Technologies (Wolters Kluwer Health), 2001-08-01) The structure and biomechanical forces on the patellar joint challenges researchers to define an ideal method for resurfacing the patellar cartilage. The articular surface of the patella presents variability between individuals, and has various minor articulations that bear partial or total compressive, shear, and combined forces during movement. Surgical techniques for the repair of patellar cartilage defects have evolved from cumulative advances in basic science and technology. Such surgeries include the ...
Possible interactions between antioxidant enzymes and free sialic acids in saliva: A preliminary study on elite judoists Cavas, L; Arpinar, P; Yurdakoc, K (Georg Thieme Verlag KG, 2005-12-01) Measurement of antioxidant enzyme activities is of great importance in the evaluation of oxidative stress in human metabolism. Sialic acids are also vital bio-markers for some diseases such as acute myocardial infarction and diabetes. In the present study, antioxidant enzyme activities (SOD, CAT, GSH-Px) and free sialic acid (FSA) levels in saliva were determined before and after training in the elite Turkish judoists (ETJ). According to the results, antioxidant enzyme activities in post-exercise values wer...
