We report a series of microarray-based comparisons of gene expression in the leaf and crown of the winter barley cultivar Luxor, following the exposure of young plants to various periods of low (above and below zero) temperatures. A transcriptomic analysis identified genes which were either expressed in both the leaf and crown, or specifically in one or the(More)
Glutamate carboxypeptidase II (GCPII) is a transmembrane glycoprotein expressed in various tissues. When expressed in the brain it cleaves the neurotransmitter N-acetylaspartylglutamate (NAAG), yielding free glutamate. In jejunum it hydrolyzes folylpoly-gamma-glutamate, thus facilitating folate absorption. The prostate form of GCPII, known as prostate(More)
Drought and low temperature are the two most significant causes of abiotic stress in agricultural crops and, therefore, they pose considerable challenges in plant science. Hence, it is crucial to study response mechanisms and to select genes for identification signaling pathways that lead from stimulus to response. The assessment of gene expression is often(More)
Elderly patients with Hodgkin's lymphoma carry a worse prognosis than younger patients because of a higher incidence of advanced stages, a worse performance status and the intolerance of full-dose curative treatment. A retrospective analysis of patients treated at our institution was performed. Our retrospective study summarizes the treatment results for 52(More)
Oxidation, cleavage and degradation of the imidazole and piperazine rings, O-dealkylation, and aromatic hydroxylation are the reported pathways of ketoconazole (KC) metabolism. Metabolites were examined in hepatic extracts from male Swiss Webster mice treated with KC (350 mg kg-1 po x 7 days) in a 0.25% gum tragacanth suspension at 10 ml kg-1. Livers were(More)
We report a series of microarray-based leaf and crown transcriptome comparisons involving three barley cultivars (cvs. Luxor, Igri and Atlas 68) which express differing degrees of frost tolerance. The transcripts were obtained following the exposure of seedlings to low (above and below zero) temperatures, aiming to identify those genes and(More)
Many clinical and forensic toxicology laboratories establish criteria for identifying a random urine specimen submitted for drug screening as being "normally concentrated" or "dilute" by incorporating creatinine analysis and/or specific gravity measurement into their testing protocols. The objective of this study is to describe the importance of urine(More)
Cold stress is a major environmental factor that limits the distribution of plants and determines the spectrum and amount of secondary metabolites with a protective function. The most studied representative of the genus Hypericum, H. perforatum L. (St. John’s wort), is known as a producer of the photodynamic pigment hypericin, the unique bioactive compound(More)
The development of dormancy, frost resistance and cryotolerance of in vitro apple plants (Malus domestica Borkh.), cv. Greensleeves during their exposure to cold hardening was studied. In vitro cultures were cold hardened at 4°C under a short photoperiod up to 25 weeks. The dormancy status, non-structural saccharides, proline, water content and frost(More)
