Karyotype analysis and FISH mapping using 45S rDNA sequences on 6 economically important plant species Anthuriumandraeanum Linden ex André, 1877, Monsteradeliciosa Liebmann, 1849, Philodendronscandens Koch & Sello, 1853, Spathiphyllumwallisii Regel, 1877, Syngoniumauritum (Linnaeus, 1759) Schott, 1829 and Zantedeschiaelliottiana (Knight, 1890) Engler, 1915 within the monocotyledonous family Ara...

Combined with a system for identifying each of the chromosomes in a genome, visualizing the location of individual genetic loci by fluorescence in situ hybridization (FISH) would aid in assembling physical and genetic maps. Previously, large genomic clones have been successfully used as FISH probes onto somatic chromosomes but this approach is complicated in species with abundant repetitive ele...

Multi-gene detection at the single-cell level is desirable to enable more precise genotyping of heterogeneous hematology and oncology samples. This study aimed to establish a single-cell multi-gene fluorescence in situ hybridization (FISH) method for use in molecular pathology analyses. Five fluorochromes were used to label different FISH gene probes, and 5 genes were detected using a five-colo...

Chromosomal aberrations play a dominant role in colorectal carcinogenesis. The application of fluorescence in situ hybridization (FISH) based techniques such as comparative genomic hybridization (CGH) and spectral karyotyping (SKY) revealed that colorectal carcinomas are characterized by a specific pattern of chromosomal imbalances which sequentially accumulate during cancer progression. This r...

Several cytogenetic markers show chromosomal diversity in the fish such as "armoured catfish". Although studies have characterized many species in the major genera representing these Siluridae, particularly in the genus Hypostomus Lacépède, 1803, trends in chromosome evolution of this group remain unclear. The Paraíba do Sul river basin contains the armoured catfish Hypostomus affinis Steindach...

A 4-year-old girl with Down syndrome exhibited an autosomal translocation t(2;18) in addition to trisomy 21. An evaluation of GTG-banded metaphases revealed the karyotype 47,XX,t(2;18),21 that was confirmed by using fluorescent in situ hybridization (FISH) probes. This case represents a very rare coincidence of an autosomal aneuploidy and a structural rearrangement. Her parents showed a normal ...

copper matrix composite reinforced by 1wt.% tib2 particles was prepared using in situ reaction of cu-1.4wt.% ti and cu-0.7wt.% b by rapid solidification and subsequent heat treatment for 1-20 hrs at 900ºc. high-resolution transmission electron microscopy (hrtem) characterization showed that primary tib2 particles were formed in liquid copper. heat treatment of as-solidified samples led to the f...

the first purpose of this study is to present an alternative robust model in order to describe ruminal degradation kinetics of forages and to minimize the fitting problems. for this purpose, the korkmaz-uckardes (ku) model, which has a logarithmic structure, was developed. the second purpose of this study is to estimate, by using the korkmaz-uckardes (ku)model, the parameters tp (the time to pr...

degradation of dry matter (dm) and nitrogen (n) in fresh or frozen-thawed alfalfa and ryegrass was studied by using in situ technique. the forages were labeled with 15n during growth in a glasshouse, harvested at similar growth phase, and fresh (f) or frozen-thawed (ft) samples were incubated in the rumen of 3 sheep. there was no difference (p>0.05) between forage type (s) for the immediately s...

in this work, the potential of auto-ignition of heavy oil during in-situ combustion (isc) process was studied. kinetic studies were carried out using thermo gravimetric analyzer (tga), differential scanning calorimetry (dsc) and accelerating rate calorimetric (arc) techniques. effects of oxygen partial pressure, reservoir pressure and clay on auto ignition condition were investigated on a numbe...
