Pancreatic ductal adenocarcinoma is one of the most difficult malignancies to diagnose and treat. The aim of this article is to review how tumor markers can aid the diagnosis and management of patients with this malignancy. The most widely used and best validated marker for pancreatic cancer is CA 19-9. Inadequate sensitivity and specificity limit the use(More)
The greenbug, Schizaphis graminum(Rondani), the Russian wheat aphid, Diuraphis noxia (Mordvilko), and the bird cherry oat aphid, Rhopalosiphum padi(L.), annually cause several million dollars worth of wheat production losses in Europe and the United States. In this study, Triticum and Aegilops accessions from the Czech Research Institute of Crop Production(More)
Mother of FT and TFL1 (MFT) participates in the regulation of seed dormancy in wheat. A single-nucleotide polymorphism (SNP) in the promoter of MFT on chromosome 3A (MFT-3A) can explain the difference in the levels of MFT-3A expression, and the difference in seed dormancy, between Chinese Spring (CS) and the CS line with a substituted chromosome 3A from(More)
Sequence tagged site (STS) markers have been developed recently to identify resistance genes in wheat. A number of wild relatives have been used to transfer resistance genes into wheat cultivars. Accessions of wild species of Triticeae: Aegilops longissima (4), Ae. speltoides (6), Ae. tauschii (8), Ae. umbellulata (3), Ae. ventricosa (3), Triticum spelta(More)
The occurence ofSipha (Rungsia) elegans is recorded in 11Aegilops species and in two wildTriticum species grown on an experimental plot in Praha-Ruzyně in 1993–1995. Abundance ofS. elegans varied in various years, and the infestation of species tested also differed. The highest aphid number, 0.91 individuals per tiller, was recorded in 1995 at the latest(More)
