Computer simulations were used to study the efficiency of marker-assisted selection (MAS) based on an index combining the phenotypic value and the molecular score of individuals. The molecular score is computed from the effects attributed to markers by multiple regression of phenotype on marker genotype. The results show that in the first generation the ratio RE of the expected efficiency of MA...

conclusions the x-intercepts (point at which the fdc crosses the x-axis) were on average more in the base-in direction, y-intercepts (point at which the fdc crosses the y-axis) were shifted in the exo direction, and slopes were steeper in the symptomatic group. results there were more subjects with exo fixation disparity than eso fixation disparity in the study sample. the means for fixation di...

OBJECTIVE Functional magnetic resonance imaging (fMRI) is frequently used to localize language areas in a non-invasive manner. Various paradigms for presurgical localization of language areas have been developed, but a systematic quantitative evaluation of the efficiency of those paradigms has not been performed. In the present study, the authors analyzed different language paradigms to see whi...

Iron deficiency in axenic cultures of Trichodesmium erythraeum IMS101 led to significant declines in both nitrogen fixation rates and photochemical energy conversion efficiency, accompanied by downregulation of genes encoding the major iron-binding proteins, including psbA and psbE of photosystem II, psaA and psaC of photosystem I, petB and petC of the cytochrome b(6)f complex, and nifH. Howeve...

The production of hydrogen (H2) is an inherent component of biological dinitrogen (N2) fixation, and there have been several studies quantifying H2 production relative to N2 fixation in cultures of diazotrophs. However, conducting the relevant measurements for a field population is more complex as shown by this study of N2 fixation, H2 consumption and dissolved H2 concentrations in the oligotro...

conclusions according to the results of our study, neck collar fixation has no effect on ventilation in multiple trauma patients. results this study involved 163 multiple trauma patients. of these, 65% were male. the mean of end tidal carbon dioxide (etco2) of the patients without neck collars was 34.62 ± 4.46 and the mean etco2 of the patients with neck collars was 34.21 ± 2.31. there was no s...

Purpose. The purpose of this article is to develop a preprocessing method for digital multispectral remote sensing images obtained through optical and infrared means in the electromagnetic spectrum. aims ensure invariance with respect positional formation conditions that determine spatial radiometric resolution. By implementing homomorphic filtering method, we can significantly increase informa...

Uncorrected bony deformity or stiffness resulting from a metacarpal shaft fracture can produce a significant functional or cosmetic deficit. Intramedullary fixation of metacarpal shaft fractures using small flexible rods can provide stable internal fixation while minimizing the extent of soft tissue trauma that is associated with more extensive surgical techniques such as plate or screw fixatio...

Background: The treatment of open tibial fractures is still an orthopaedic challenge and full of complications. In many cases the use of external fixator that has been known as a non-union machine is obligatory with a high incidence of pin track infection and other complications. The aim of this study was to compare the use of external fixation as a definite method for treatment of open tibial ...

  Background: Pelvic ring injuries and sacroiliac dislocations have significant impacts on patient’s quality of life. Several techniques have been described for posterior pelvic fixation. The current study has been designed to evaluate the spinopelvic method of fixation for sacroiliac fractures and fracture-dislocations.   Methods: Between January 2006 and December 2014, 14 patients with sacroi...
