Imaging of nitric oxide in a living vertebrate using a diaminofluorescein probe
2007
Abstract Numerous approaches have been described to identify nitric oxide (NO), a free radical involved in various physiological and pathophysiological processes. One of these approaches is based on the use of chemical probes whose transformation by NO generates highly fluorescent derivatives, permitting detection of NO down to nanomolar concentrations. Here, we show that the cell-permeant diaminofluorophore 4-amino-5-methylamino-2′-7′-difluorofluorescein diacetate (DAF-FM-DA) can be used to detect NO production sites in a living vertebrate, the zebrafish Danio rerio. The staining pattern obtained in larvae includes the bulbus arteriosus, forming bones, the notochord, and the caudal fin. Th…
Alterations in the organization of the isocortical layer I in trisomy 22.
1999
The isocortical layer I of human fetal brains obtained from different cases of chromosomal abnormalities (trisomy 18, 21, 22) and controls without pathological disturbances were investigated histologically and immunohistochemically by using the antibodies SMI 311, SMI 35 and SMI 81 (SNAP 25) as well as antibodies against GAP 43 and calretinin. In cases of trisomy 22 the Cajal-Retzius cells in Nissl-sections and in SMI 311-immunopreparations do not reveal any alterations regarding their location or morphology. However, the axonal plexus, selectively labelled with SMI 35, normally located in layer Ib, is malpositioned in Ia. Likewise, SNAP 25- and GAP 43-immunoreactive structures, which were …
Analysis of Air Cycle and Efficiency Evaluation for a Blast Freezing Tunnel Plant
2013
Air refrigerating systems offer a suitable alternative to vapour compression systems. Air can be used as working fluid in gas compression cycles for refrigeration, air conditioning and heat pump systems. This paper gives some results of theoretical investigation into improved air cycles for refrigeration systems and a comparison is made with their performances. The case-study relates to a dual purpose refrigerating plant. A blast freezing tunnel gives the coldest air stream and, in cascade, the air coming out from the tunnel is used in a channel network for feeding a lot of chilling cells. The case-study analysed indicates that there is a real possibility to build plants which will be equip…
A Snapshot of the World of Global Multinationals – An Industry Based Analysis of Fortune Global 500 Companies
2017
Abstract For better or for worse, the “corporations rule the world” assertion is nowadays more actual and accurate than ever before, as multinational companies represent the undisputable engine of the globalization process, and the latter continuously (re)creates the background against which global multinationals are flourishing, while reinforcing their “domination”. Since 1995, the Fortune Global 500 ranking (FG 500) annually provides a comprehensive and eloquent image of the world of global multinationals; the merits of the FG 500 ranking go beyond the synchronic approach of the characteristics of global multinationals (in terms of revenues, profits, assets and employees - by sector, indu…
Naratīvu izpausmes sociālajos tīklos: Stāsta ("Story") funkcija sociālajās platformās Snapchat, Instagram, Facebook un Whatsapp
2017
Bakalaura darbā “Naratīvu izpausmes sociālajos tīklos: Stāsta ("Story") funkcija sociālajās platformās Snapchat, Instagram, Facebook un Whatsapp” ir apskatīts, kādi ir jaunu cilvēku sociālo platformu “story” jeb stāsta sadaļas lietošanas paradumi. Darba mērķis: noskaidrot, vai lietotāji izmanto “story” funkciju, konstatēt satura atšķirības starp sadaļām, noskaidrot, kā izmaiņas kopējā sociālā tīkla profila naratīvā ietekmē izpratni par laiku, un vai lietotāji savu sociālo tīklu profilu izmanto kā dienasgrāmatu. Darba teorētiskajā daļā apskatīts, kas ir sociālie mediji un sociālie tīkli, mobilie digitālie sociālie tīkli, “story” funkcija, naratīvs un cilvēku izpratne par laiku. Pētījuma ietv…
A multiplex SNP typing approach for the DNA pyrosequencing technology
2006
Abstract We have developed a multiplex Pyrosequencing assay which enables the simultaneous analyses of 23 single nucleotide polymorphisms (SNPs) from the human genome selected by the SNPforID Consortium. In our investigations we have studied the multiplex capacity of the PSQ™ 96MA instrument (Biotage AB). To test the reliability of SNP typing by Pyrosequencing the SNPs were analysed in parallel by using the SNaPshot minisequencing technique as reference method.
Introduction to the Issue on Advances in Remote Sensing Image Processing
2011
The papers in this special issue span a wide range of problems arising in modern remote sensing data analysis and provide a snapshot in the state-of-the-art of remote sensing image processing. More advances are expected in the near future, mainly due to the increasing user demands in terms of spatial, spectral, and temporal resolutions of data, and of products generated from these data by automatic processing techniques.

The stem rust resistance gene Rpg5 encodes a protein with nucleotide-binding-site, leucine-rich, and protein kinase domains
2008
We isolated the barley stem rust resistance genes Rpg5 and rpg4 by map-based cloning. These genes are colocalized on a 70-kb genomic region that was delimited by recombination. The Rpg5 gene consists of an unusual structure encoding three typical plant disease resistance protein domains: nucleotide-binding site, leucine-rich repeat, and serine threonine protein kinase. The predicted RPG5 protein has two putative transmembrane sites possibly involved in membrane binding. The gene is expressed at low but detectable levels. Posttranscriptional gene silencing using VIGS resulted in a compatible reaction with a normally incompatible stem rust pathogen. Allele sequencing also validated the candi…
The ineffectiveness of the NO-cyclic GMP signaling pathway in the atrial myocardium
1995
1. This study was performed to determine whether nitric oxide (NO) has direct effects on force of contraction (Fc) in atrial myocardium from rats, rabbits, guinea-pigs, frogs, and man. 2. Glyceryl trinitrate, isosorbide dinitrate, 3-morpholino-sydnonimine hydrochloride (SIN-1), and S-nitroso-N-acetylpenicillamine (SNAP) did not significantly reduce Fc in the various preparations investigated, either given alone or after stimulation of alpha- or beta-adrenoceptors. 3. SNAP did not change the time course of contractions in rat, guinea-pig and human preparations. 4. 8-Bromo-guanosine-3':5'-cyclic monophosphate (8-Br-cyclic GMP) produced a negative inotropic effect in rat, guinea-pig and human …
