objective: the current methods for bladder cancer diagnosis suffer from low sensitivity and specificity. therefore, finding a novel tumor markers with high specificity and sensitivity is of great interest. micrornas (mirna, mir) are small endogenously-produced, non-coding rnas with an important role in regulating gene expression. recent studies show that mirnas expression profiles represent sig...

to determine the role of ddx3y gene in spermatogenesis and infertility in bulls, blood samples were collected from five infertile bulls (azoospermic; no sperm in the semen) at the animal breeding center in karaj, iran. the recommended human primers by eaa/eqmn were investigated using the blastn database for sts marker detection. alignment of sts marker genes with bovine genome was performed. pr...

linked and/or gene-based molecular markers have been used widely in marker-assisted selection (mas) to differentiate resistant and susceptible genotypes. resistance to meloidogyne spp. in beta vulgaris l. is mediated by a single dominant gene (r6m-1). using allele-specific primers (asps), an snp marker harboring a single nucleotide polymorphism (a/g), linked to the resistance gene was developed...

background: despite the extensive information available in the literature, cell surface marker signature of human amniotic epithelial cells (haecs) remains controversial. the aim of the present study was to characterize immuno-phenotypic features, proliferative capacity and immunogenicity of haecs. we also tested whether expression of some cell surface markers is influenced by the type of tryps...

to evaluate the genetic variations in eleven fennel populations in iran, 55 accessions were analyzed by srap markers. twelve primer combinations produced 171 polymorphic bands. the cumulative dendrogram delineated fennel accessions into five major groups in accordance to the geographical regions from which the populations were originated. about 43.57% of total genetic variation was detected amo...

Non-invasive surface registration methods have been developed to register and track breathing motions in a patient's abdomen and thorax. We evaluated several different registration methods, including marker tracking using a stereo camera, chessboard image projection, and abdominal point clouds. Our point cloud approach was based on a time-of-flight (ToF) sensor that tracked the abdominal surfac...

In an attempt to transduce monocyte-derived dendritic cells (DCs) by a retroviral vector coding for a cell surface marker, we were confronted by the observation of high transfer of the surface molecule in the absence of vector proviral DNA in the treated cells. Indeed, DCs acquired the surface marker by a mechanism independent of the vector machinery, requiring cell-to-cell contact and involvin...

This paper describes a 3-D gait analysis system, which combines optoelectric motion tracking and a standardized X-ray procedure, to calculate the net knee-joint forces and moments of a normal subject group during walking. The optoelectric system collects kinematic data from infra-red LED markers placed at selected skin surface locations and projecting probes attached to the lower limb. A standa...

Blood or bone marrow specimens from 22 patients with chronic myelogenous leukemia in blast crisis were studied for the surface expression of glycophorin-A, a marker for early erythroid differentiation. The leukemic blasts were stained with rabbit anti-glycophorin-A antiserum. The glycophorin-A molecules detected by the rabbit antiserum were identified by polyacrylamide slab gel electrophoresis ...

A method is described for the use of scanning electron microscopy on the surface of gold-labeled cells. It includes the use of 45- or 20-nm colloidal gold marker conjugated with Staphylococcal protein A. The marker is best recognized on the basis of its atomic number contrast by using the backscattered electron imaging mode of the scanning electron microscope. When the backscattered electron si...
