We investigated the movement of interstitially infused macromolecules within the central nervous system (CNS) in rats with high and low blood pressure (BP)/heart rate and in rats euthanized immediately before infusion (no heart action). Adeno-associated virus 2 (AAV2), fluorescent liposomes, or bovine serum albumin was infused into rat striatum (six(More)
Increased expression of the high molecular weight glutenin subunit (HMW-GS) Bx7 is associated with improved dough strength of wheat (Triticum aestivum L.) flour. Several cultivars and landraces of widely different genetic backgrounds from around the world have now been found to contain this so-called ‘over-expressing’ allelic form of the Bx7 subunit encoded(More)
Bánkúti 1201, an old Hungarian wheat variety with special quality traits, was analysed to determine the relationships between its storage protein composition and superior quality-attributes for breadmaking. Based on the storage protein composition, the variety appears to have the nature of a population, containing several genotypes with different gluten(More)
The synthetic cholera toxin B subunit (CTB) gene, modified according to the optimized codon usage of plant genes, was introduced into a plant expression vector and expressed under the control of the Bx17 HMW (high molecular weight) wheat endosperm-specific promoter containing an intron of the rice act1. The recombinant vector was transformed into rice(More)
The recently achieved significant improvement of cereal transformation protocols provides facilities to alter the protein composition of the endosperm, for example, to increase or decrease the quantity of one of its protein components or to express foreign molecules. To achieve this goal, strong endosperm-specific promoters have to be available. The aim of(More)
An amaranth (Amaranthus hypochondriacus) albumin gene, encoding the 35-kDa AmA1 protein of the seed, with a high content of essential amino acids, was used in the biolistic transformation of bread wheat (Triticum aestivum L.) variety Cadenza. The transformation cassette carried the ama1 gene under the control of a powerful wheat endosperm-specific promoter(More)
 The isolation and characterisation by DNA sequencing of two different low molecular weight glutenin subunit (LMW-GS) genes from a genomic library derived from Triticum tauschii is described. These genes are similar (more than 90% similarity) but not identical to previously published LMW-GS gene sequences from cultivated wheats. A comparison of nucleotide(More)
BACKGROUND The aim of the study was to determine the role of quantitative pathological parameters in prognosis of head and neck malignancies. MATERIALS AND METHODS 51 head and neck squamous cell carcinoma patients were examined for mutant p53 gene expression (45 out of 51 patients) by immunohistochemistry and for cellular DNA-content (44 out of 51(More)
Epitopes often require co-delivery with adjuvant and targeting proteins to enable recognition by the immune system, and this approach may also increase the efficacy of the antigen. In this study, we assess and describe the ability of transgenic rice plants to express a fusion protein consisting of the B-subunit of the Escherichia coli heat-labile(More)
Transcriptional regulation of LMW glutenin genes were investigated in-silico, using publicly available gene sequences and expression data. Genes were grouped into different LMW glutenin types and their promoter profiles were determined using cis-acting regulatory elements databases and published results. The various cis-acting elements belong to some(More)
