Background: Metastasis and recurrence of colorectal cancer after treatment is attributed to stem cells. The aim of this study was to determine the relationship between the expression of stem cell marker CD166 in colorectal cancer by immunohistochemistry and clinicopathologic parameters.Methods: From 2006 to 2012, 121 colectomy specimens of patients with colon cancer that were operated in Babol...

(4/12) of the treatments called useful will be false positives. Of course, the false positive rate rises above 5% as the number of tests of statistical significance performed increases. In this connection, Tannock reported that subgroup analyses were done in 59% of 32 randomized trials published in the New England Journal of Medicine or the Journal of Clinical Oncology, with corrections for mul...

We describe an augmented reality (AR) marker that has both a virtual appearance and physical features. We integrate a blimp with an AR marker to overcome two problems found in conventional AR applications. One problem is mobility. While a conventional AR marker is generally paper-based and static, “Aero-Marker” floats in the air and moves toward the user. Thus, the relationship between the user...

To validate if DCX truly predicts neuron recruitment throughout the canary brain, it should correlate to a high degree with established methods for studying neuron recruitment, such as labeling cells with the mitotic marker 5-bromo-2-deoxyuridine (BrdU). This is not the case, however, as we observed clear regional differences in the relationship between the two labeling methods in neurogenic an...

seedlessness is the most important trait in table grape and raisin industry which has attracted breeders from long ago. breeding grapes by traditional methods result in low number of seedless progenies and their selection requires long time. therefore, marker-assisted selection (mas) can overcome the selection difficulty and would decrease high cost of progeny maintenance for several years. in ...

mahaleb (prunus mahalab l.) is used as a rootstock for cherries in iran and many other countries. in this research, rapd markers were used to determine the genetic diversity among eight genotypes of mahaleb evaluated in two separate research grardens in karaj, iran. these genotypes are used as mother plants for seed production. totally 40 random primers were examined for pcr reactions on the te...

background : hepatitis includes a wide range of clinical and pathological conditions. the beta-2 microglobulin (ãÿ2m), as part of thehla complex, is responsible for transmission of viral antigens on the surface of liver cells. the purpose of this study is to determine the concentration of salivary ãÿ2m as a marker of viral proliferation in subjects who are hbsag + , hbv dna pcr + compared with ...

background: garlic is a valuable medicinal plant with variability in desirable morphological and physiological characteristics. the analysis of genetic diversity plays an important role in breeding programs. the rapd technique could be very effective in detecting genetic variation in garlic.  objective: the objective of the present work was to detect molecular polymorphism among iranian garlic ...
