Purpose Malignant hyperthermia (MH) is a potentially fatal hypermetabolic condition triggered by certain anesthetics and caused by defective calcium homeostasis in skeletal muscle cells. Recent evidence has revealed impairment of various biochemical pathways in MH-susceptible patients in the absence of anesthetics. We hypothesized that clinical differences between MH-susceptible and control individuals are reflected in measurable differences in myoplasmic metabolites. Methods We performed metabolomic profil...
Unsupervised segmentation of hyperspectral images using modified phase correlation
Ertuerk, Alp; Ertuerk, Sarp (2006-10-01)
This letter presents hyperspectral image segmentation based on the phase-correlation measure of subsampled hyperspectral data, which is referred to as modified phase correlation. The hyperspectral spectrum of each pixel is initially subsampled to gain, robustness against noise and spatial variability, and phase correlation is applied to determine spectral similarity. Similar and dissimilar pixels are decided according to the peak value of the phase correlation result to determine pixels that fall into the s...
Unsupervised building detection in complex urban environments from multispectral satellite imagery
AYTEKİN, Orsan; Erener, Arzu; Ulusoy, İlkay; Duzgun, Sebnem (2012-01-01)
A generic algorithm is presented for automatic extraction of buildings and roads from complex urban environments in high-resolution satellite images where the extraction of both object types at the same time enhances the performance. The proposed approach exploits spectral properties in conjunction with spatial properties, both of which actually provide complementary information to each other. First, a high-resolution pansharpened colour image is obtained by merging the high-resolution panchromatic (PAN) an...
Multielement analysis of iliac crest bone by neutron activation
Aras, NK; Ertaş, Gülay; Korkusuz, F; Olmez, I; Sepici, B; Eksioglu, F; Bode, P (2000-04-01)
Bone samples from iliac crest were obtained from apparently healthy female (n=4) and male (n=8) subjects with ages between 15-50. Cortical and trabecular parts were separated and soft tissues like fat, muscle and blood were removed. Calcium, Mg, Na, Cl, Fe, Zn, Br, Sr, and Cs were determined by instrumental neutron activation analysis and other techniques, and their relations were discussed. Fairly good agreement was obtained with literature data. These values may serve as reference values for subjects from...
