Rice is one the most important crops in Iran and worldwide. Abiotic stresses including cold, restrict rice production. In order to saturation of linkage map in recombinant lines population caused by Sepidroud × Anbarbou crosses, an experiment was conducted using 96 recombinant lines and 40 ISSR markers at Gonbad Kavous University. 96 Recombinant lines were plant under hydroponic conditions fo...
small supernumerary marker chromosomes (ssmc) are still a major problem in clinical cytogenetics as they cannot be identified or characterized unambiguously by conventional cytogenetics alone. on the other hand, and perhaps more importantly in prenatal settings, there is a challenging situation for counseling how to predict the risk for an abnormal phenotype, especially in cases with a de novo ...
INTRODUCTION Radiostereometric analysis has demonstrated its capacity to track precise motion of the bones within a subject during motion. Existing devices for imaging the body in two planes are often custom built systems; we present here the design and marker-based validation of a system that has been optimized to image the foot during gait. METHODS Mechanical modifications were made to pair...
MOTIVATION Identification of differentially expressed genes is a major issue in gene expression data analysis and selection of marker genes is critical in tumor classification using gene expression data. In this paper, we propose a semiparametric two-sample test to identify both differentially expressed genes and select marker genes for sample classification. RESULTS A simulation study shows ...
The problem of hip joint centre location using optical markers located on the skin is addressed. We present a novel computational technique which can recover joint centre location based solely on the marker measurements. In addition a quantitative estimate of the uncertainty in joint centre location is obtained. We also present some preliminary experimental validation of the technique on a rigi...
Although O(6)-methylguanine DNA methyltransferase (MGMT) promoter methylation status is an important marker for glioblastoma multiforme (GBM), there is considerable variability in the clinical outcome of patients with similar methylation profiles. The present study aimed to refine the prognostic and predictive value of MGMT promoter status in GBM by identifying a micro (mi)RNA risk signature. D...
MALDI imaging mass spectrometry represents a new analytical tool to directly provide the spatial distribution and relative abundance of proteins in tissue. Twenty-five ovary carcinomas (stages III and IV) and 23 benign ovaries were directly analyzed using MALDI-TOF MS. The biomarker with the major prevalence (80%) has been fully identified using MALDI MS and nanoESI MS and MS/MS after separatio...
Recent investigation has identified association of IL-12p40 blood levels with melanoma recurrence and patient survival. No studies have investigated associations of single-nucleotide polymorphisms (SNPs) with melanoma patient IL-12p40 blood levels or their potential contributions to melanoma susceptibility or patient outcome. In the current study, 818,237 SNPs were available for 1,804 melanoma ...
In this paper an object recognition and tracking approach for the mobile, marker-less and PDA-based augmented reality system AR-PDA is described. For object recognition and localization 2D features are extracted from images and compared with a priori known 3D models. The system consists of a 2D graph matching, 3D hypothesis generation and validation and an additional texture based val-
26 Peatlands are widely exploited archives of palaeoenvironmental change. We developed and 27 compared multiple transfer functions to infer peatland depth to the water table (DWT) and pH 28 based on testate amoeba (percentages or presence/absence), bryophyte presence/absence and 29 vascular plant presence/absence data from sub-alpine peatlands in the SE Swiss Alps in order 30 to compare the per...
