Pro-enkephalin opioid peptides are abundant in porcine and bovine splenic nerves, but absent from nerves of rat, mouse, hamster, and guinea-pig spleen
1995
The opioidergic innervation of the mammalian spleen and possible species differences were investigated. Light-microscopic immunohistochemistry revealed that splenic nerves of bovine and porcine spleen, but not of rat, mouse, hamster and guinea-pig spleen contained proenkephalin-derived opioidergic innervation. Immunoreactivity to both prodynorphin and pro-opiomelanocortin was absent from splenic nerves. In bovine and porcine spleen, fibers immunoreactive for met-enkephalin, met-enkephalin-Arg-Phe, met-enkephalin-Arg-Gly-Leu, leu-enkephalin and peptide F formed perivascular plexus, traveled in trabecular connective tissue, and extended into the capsule. Spatial relationships with immune cell…
Differences in the activity and distribution of peroxidases from three different portions of germinating Brassica oleracea seeds
2002
Peroxidase (POD, EC 1.11.1.7) activity, cellular localization and isozyme patterns were investigated in the seed integument, cotyledon and embryo axis of Brassica oleracea cv. Cappuccio during pregermination and seedling growth. Seeds started to germinate after 24 h of imbibition. POD activity was localized in the pigmented layer of the integument and in procambial strands of the cotyledon and embryo axis in the first 24 h of imbibition. It was localized in the integumental cells of palisade, pigmented and aleurone layers and in epidermal, meristematic, procambial cells and xylem elements of the root and hypocotyl after 48 h of imbibition. POD activity increased during germination and early…
Global and local interactions in football: Comparing the development paths of Finland and Hungary
2018
The aim of this study is to increase understanding of football’s global and local contexts. More specifically, the development paths of Finnish and Hungarian football are explored and compared in four research articles from different perspectives within a global framework. These viewpoints, in addition to a historical-sociological overview in the article I, cover closely interrelated phenomena observable in the landscape of top-level football: the organization of elite youth football, the professionalization of players and the development of football stadiums. The main research question of the study is as follows: In what way have glocal interactions in men’s football shaped the development…
NOTES ON THE BIOMETRY, ORIENTATION AND SPATIAL LOCALIZATION OF THE NESTS OF THE GLOBALLY NEAR-THREATENED STRAIGHT-BILLED REEDHAUNTER (LIMNOCTITES REC…
2017
We report the records of three nests of Straight-billed Reedhaunter, Limnoctites rectirostris, in southernmost Brazil. For each nest, we collected information about the biometry, spatial localization within the patch (border or inland) and cardinal orientation of the incubation chamber. Information on number of eggs and reproductive success is also presented. All nests were found early in September. The three nests were situated on the edge of patches and guided incubation chamber opening between north and east. All results are discussed. The information presented herein extends the scarce knowledge about the breeding biology of the Straight-billed Reedhaunter. Key words: breeding biology, …
Revealing Hidden Histories with Modern Technology : Archaeological Information Systems and Geolocalization
2016
It has been long since it was enough for museums to be simply repositories of objects and hubs of research and knowledge. Public education and sharing of knowledge has always been part of museum ideology but today many museums are striving to engage and enthral their audiences in a world filled with pastime entertainment. Nonetheless, this challenge is not novel but one of the fundamental questions of museum pedagogy: How to present past and distant cultures as lived histories, as lives lived in places and environments now either empty or over taken by new inhabitants and their way of life? How to present the world stored inside the museum as interconnected with the living, changing everyda…
AMPA Receptor Auxiliary Proteins of the CKAMP Family
2019
α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are assembled of four core subunits and several additional interacting proteins. Cystine-knot AMPA receptor-modulating proteins (CKAMPs) constitute a family of four proteins that influence the trafficking, subcellular localization and function of AMPA receptors. The four CKAMP family members CKAMP39/shisa8, CKAMP44/shisa9, CKAMP52/shisa6 and CKAMP59/shisa7 differ in their expression profile and their modulatory influence on AMPA receptor function. In this review, I report about recent findings on the differential roles of CKAMP family members.
The effect of nanoparticle size and NLS density on nuclear targeting in cancer and normal cells; impaired nuclear import and aberrant nanoparticle in…
2017
The cell nucleus is an interesting target in many diseases with particular interest in cancer. Previously, nuclear targeted small and large chitosan nanoparticles (S-NPs≈25nm, and L-NPs≈150nm respectively), modified with low, intermediate and high densities of NLS (L-NLS, I-NLS and H-NLS) were developed and assessed in L929 fibroblasts. However, to evade apoptosis and stimulate tumor growth cancer cells are capable of manipulating the nuclear-cytoplasmic transport on many levels, making NPs that are capable of nuclear targeting in normal cells incapable of doing so in cancer. For such reason, here, the nuclear delivery efficiency of S-NPs and L-NPs was assessed as a function of their NLS de…
The identification and localization of two intermediate filament proteins in the tunic of Styela plicata (Tunicata, Styelidae).
2009
The intermediate filament (IF) proteins Styela C and Styela D from the tunicate Styela (Urochordata) are co-expressed in all epidermal cells and they are thought to behave as type I and type II keratins. These two IF proteins, Styela C and Styela D, were identified in immunoblots of proteins isolated from the tunic of Styela plicata. The occurrence and distribution of these proteins within the tunic of this ascidian was examined by means of immunofluorescence and immunoperoxidase techniques, using anti-Styela C and anti-Styela D antibodies. In addition, immuno-electron microscopy of the tunic showed that the two proteins are located in the cuticle layer and in the tunic matrix. These result…
PREMISES OF GASTRONOMIC TOURISM
2013
Since the competition among tourism destinations has risen, local culture has developed into a competitive advantage and a priceless resource of new products and services to attract and captivate tourists. Gastronomy plays a vital role in the process of attracting tourists because food has an important part in the tourist experience, plus gastronomy developed over the year's styles and tastes and become a critical source of establishing patterns in postmodern civilization.
