Importance of millipedes (Diplopoda) in the autumn-winter diet of Scolopax rusticola

2019

Authors examined the autumn-winter diet of the woodcock Scolopax rusticola from 407 gizzard samples originating from Crimea and Italy, resulting in a high number of millipedes (Diplopoda) in all the samples; this prey item was particularly important in terms of weight percentage. The authors consider that calcium, highly present in millipedes, should be an important source for the woodcocks’ metabolism during the autumn-winter seasons.

The mitogen-activated protein kinase p38 pathway is conserved in metazoans: Cloning and activation of p38 of the SAPK2 subfamily from the sponge Sube…

2000

Our recent data suggest that during auto- and allograft recognition in sponges (Porifera), cytokines are differentially expressed. Since the mitogen-activated protein kinase (MAPK) signal transduction modulates the synthesis and release of cytokines, we intended to identify one key molecule of this pathway. Therefore, a cDNA from the marine sponge Suberites domuncula encoding the MAPK was isolated and analyzed. Its encoded protein is 366 amino acids long (calculated Mr 42 209), has a TGY dual phosphorylation motif in protein kinase subdomain VIII and displays highest overall similarity to the mammalian p38 stress activated protein kinase (SAPK2), one subfamily of MAPKs. The sponge protein w…

Conservation of the positions of metazoan introns from sponges to humans

2002

Abstract Sponges (phylum Porifera) are the phylogenetic oldest Metazoa still extant. They can be considered as reference animals (Urmetazoa) for the understanding of the evolutionary processes resulting in the creation of Metazoa in general and also for the metazoan gene organization in particular. In the marine sponge Suberites domuncula , genes encoding p38 and JNK kinases contain nine and twelve introns, respectively. Eight introns in both genes share the same positions and the identical phases. One p38 intron slipped for six bases and the JNK gene has three more introns. However, the sequences of the introns are not conserved and the introns in JNK gene are generally much longer. Intron…

Emergence and Disappearance of an Immune Molecule, an Antimicrobial Lectin, in Basal Metazoa

2003

Sponges (phylum Porifera) represent the evolutionarily oldest metazoans that comprise already a complex immune system and are related to the crown taxa of the protostomians and the deuterostomians. Here, we demonstrate the existence of a tachylectin-related protein in the demosponge Suberites domuncula, termed Suberites lectin. The MAPK pathway was activated in response to lipopolysaccharide treatment of the three-dimensional cell aggregates, the primmorphs; this process was abolished by the monosaccharide D-GlcNAc. The cDNA encoding the S. domuncula lectin was identified and cloned; it comprises 238 amino acids (26 kDa) in the open reading frame. The deduced protein has one potential trans…

First report on the helminthfauna of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula

2016

Summary Information about the prevalence of helminth parasites of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula is almost non-existent and there is no reliable data reported from Spain. Fourteen A. flavicollis from the Erro River valley (Navarre, Spain) were examined for endoparasites, between February 2001 and July 2002. Thirteen specimens (92.9 %) of the total sample were parasitized by at least one of the following six helminth species: one trematode (Corrigia vitta), one cestode (Taenia parva larvae) and four nematodes (Trichuris muris, Calodium hepaticum, Heligmosomoides polygyrus and Syphacia stroma). This is the first report about the helminthfauna of A. fla…

Rearing background and exposure environment together explain higher survival of aquaculture fish during a bacterial outbreak

2019

1.Parasitic diseases represent one of the greatest challenges for aquaculture worldwide and there is an increasing emphasis on ecological solutions to prevent infections. One proposed solution is enriched rearing, where traditional stimulus‐poor rearing tanks are equipped with different types of structures to increase habitat complexity. Such spatial enrichment is known to increase survival of fish during parasite epidemics, but the underlying mechanisms are still unclear. 2.We studied whether enriched rearing affected infection of an important fish pathogen Flavobacterium columnare in young Atlantic salmon (Salmo salar) and sea‐migrating brown trout (Salmo trutta). First, we used natural b…

Mediating Effects of Global Negative Effect Expectancies on the Association between Problematic Cannabis Use and Social Anxiety

2017

The relationship between social anxiety and cannabis use among adolescents and young adults is a highly debated topic. In this cross-sectional study, we tested whether cannabis use expectancies mediated the association between social anxiety and cannabis use severity in a sample of 343 young adults (74.3% male) who used cannabis. They completed self-report measures for the screening of problematic cannabis use (Cannabis Use Problems Identification Test) and social anxiety symptoms (Social Interaction Anxiety Scale and Social Phobia Scale). A multiple mediation analysis was used to test whether marijuana effect expectancies mediate social anxiety effect on problematic cannabis use. Social an…

Publiskais iepirkums kā preču pakalpojumu brīvas pārrobežu aprites veicināšanas instruments Eiropas Savienībā

2018

Publiskais iepirkums ir Eiropas Savienības vienotā (arī kopējā, iekšējā) tirgus veidošanas procesa daļa. Tāpēc svarīgi identificēt pārrobežu iepirkumu kavējošos šķēršļus preču, pakalpojumu un būvdarbu brīvai apritei un meklēt risinājumus to novēršanai. Bakalaura darba “Publiskais iepirkums kā preču un pakalpojumu brīvas pārrobežu aprites veicināšanas instruments Eiropas Savienībā” mērķis ir izstrādāt priekšlikumus iepirkumu regulējuma un tā piemērošanas pilnveidei Direktīvas 2014/24/ES kontekstā. Mērķa sasniegšanai izvirzīti uzdevumi analizēt publiskā iepirkuma vietu vienotajā tirgū un pārrobežu publisko iepirkumu veicinošos un ierobežojošos faktorus. Vienveidīgas piemērošanas veicināšanai …
