The oil palm (Elaeis guineensis Jacq.) is one of the major cultivated crops among economically important species. It mainly for its edible oil. For a perennial crop like palm, use Marker Assisted Selection (MAS) techniques helps to reduce breeding cycle and improve economic products. Genetic physical maps are sequencing experiments since they show exact positions genes other distinctive feature...
Genotype imputation from low-density to high-density (SNP) chips is an important step before applying genomic selection, because denser chips can provide more reliable genomic predictions. In the current research, the accuracy of genotype imputation from low and moderate-density panels (5K and 50K) to high-density panels in the purebred and crossbred populations was assessed. The simulated popu...
CD44, a cancer stem cell (CSC)-related surface marker, correlates with local control after radiotherapy of early laryngeal cancer. For the first time, a CSC-related marker has been functionally validated for radiotherapy in patients. CD44 expression bears the potential to predict the outcome of radiotherapy by assessment of CSC density.
The increase in the number of available markers for many experimental populations has led to QTL studies with ever increasing marker numbers and densities. The resulting conundrum is that as marker density increases, so does the multiple testing problem. It is important to re-examine the detection of multiple QTL in light of increasing marker density. We explore through simulation whether exist...
Only a few genetic maps based on recombinant inbred line (RIL) and backcross (BC) populations have been developed for tetraploid groundnut. The marker density, however, is not very satisfactory especially in the context of large genome size (2800 Mb/1C) and 20 linkage groups (LGs). Therefore, using marker segregation data for 10 RILs and one BC population from the international groundnut commun...
AIM To compare endoglin (CD105) and the pan-endothelial marker CD31 in the assessment of angiogenesis in glioblastoma and to evaluate their values in the prognosis of this malignancy. METHODS Forty-six cases of glioblastoma were included in this retrospective study. All cases were immunohistochemically stained for endoglin (CD105), CD31, vascular endothelial growth factor (VEGF), and MIB-1 (K...
Figure 2: Targeting images, needle visualization images, and gold marker image of clinical procedure using the transrectal prostate intervention system. Top image row: Suspicious targets (red cross hairs) were selected on axial TSE T2-weighted images. Second image row: The needle tip void was visualized in axial TSE proton density images. The desired targets match the actual position of the nee...
Marker-assisted selection holds promise because genetic markers provide completely heritable traits than can be measured at any age in either sex and that are potentially correlated with traits of economic value. Theoretical and simulation studies show that the advantage of using marker-assisted selection can be substantial, particularly when marker information is used, because normal selection...
