BACKGROUND The evolution and correlation between the aortic neck and distally located iliac necks after endovascular treatment of abdominal aortic aneurysms (AAAs) was studied. METHODS Of 179 patients who had undergone AAA repair between 2003 and 2007, 61 received the same radiologic follow-up and were included in this retrospective study. Data for 61 aortic necks and 115 iliac arteries were ...

The unprecedented wheat yield increases during the Green Revolution were achieved through introduction of Reduced height (Rht)-B1b and Rht-D1b semi-dwarfing alleles. These Rht-1 alleles encode growth-repressing DELLA genes containing a stop codon within their open reading frame that confers gibberellin (GA)-insensitive semi-dwarfism. In this study, we successfully took hurdle detecting wild-typ...

In guanine nucleotide-binding regulatory protein- (G protein) coupled receptors, an amphipathic alpha-helix has been postulated to be the common structural determinant in the NH2- and COOH-terminal portions of the third intracellular loop representing the major interaction site with the G proteins. Here we assessed the ability of six peptides derived from these sites of the human dopamine D1-, ...

The RNAi-mediated silencing of Pina and Pinb, the two genes responsible for the grain texture of allohexaploid wheat, was induced and analysed in two wheat cultivars, Kontesa and Torka. A characterization of the two genes in non-transgenic plants revealed that Pinb carries a point mutation, designated Pinb-D1c in both cultivars. This mutation does not influence transcript abundance or protein c...

The transferrins are a group of iron-binding glucoproteins migrating in the 3-globulin region on starch gel electrophoresis (Smithies and Hiller, i959). Commonly, there is a single iron-binding band called transferrin C, but faster (B variants) and slower (D variants) migrating bands are occasionally present. They are termed in order of electrophoretic mobility towards the anode Bo, Bo-i, B1, B...

The introduction of the Reduced height (Rht)-B1b and Rht-D1b semidwarfing genes led to impressive increases in wheat (Triticum aestivum) yields during the Green Revolution. The reduction in stem elongation in varieties containing these alleles is caused by a limited response to the phytohormone gibberellin (GA), resulting in improved resistance to stem lodging and yield benefits through an incr...

Dopamine, one of main modulatory neurotransmitters of the nervous system acts on target cells through two classes of G protein-coupled receptors, D1 and D2. The two dopamine receptor classes display different structures, interact with different regulatory partners (including heterotrimeric G proteins) and, accordingly, have independent evolutionary origins. In vertebrates, each of these recepto...

The effects of dwarfing alleles (reduced height, Rht) in near isogenic lines on wheat grain quality are characterised in field experiments and related to effects on crop height, grain yield and GA-sensitivity. Alleles included those that conferred GA-insensitivity (Rht-B1b, Rht-B1c, Rht-D1b, Rht-D1c) as well as those that retained GA-sensitivity (rht(tall), Rht8, Rht8 + Ppd-D1a, Rht12). Full ch...
