A genome-wide association study of marginal zone lymphoma shows association to the HLA region
2015
Marginal zone lymphoma (MZL) is the third most common subtype of B-cell non-Hodgkin lymphoma. Here we perform a two-stage GWAS of 1,281 MZL cases and 7,127 controls of European ancestry and identify two independent loci near BTNL2 (rs9461741, P=3.95 × 10−15) and HLA-B (rs2922994, P=2.43 × 10−9) in the HLA region significantly associated with MZL risk. This is the first evidence that genetic variation in the major histocompatibility complex influences MZL susceptibility.
Analyzing Illumina Gene Expression Microarray Data from Different Tissues: Methodological Aspects of Data Analysis in the MetaXpress Consortium
2012
Microarray profiling of gene expression is widely applied in molecular biology and functional genomics. Experimental and technical variations make meta-analysis of different studies challenging. In a total of 3358 samples, all from German population-based cohorts, we investigated the effect of data preprocessing and the variability due to sample processing in whole blood cell and blood monocyte gene expression data, measured on the Illumina HumanHT-12 v3 BeadChip array. Gene expression signal intensities were similar after applying the log(2) or the variance-stabilizing transformation. In all cohorts, the first principal component (PC) explained more than 95% of the total variation. Technic…

Biofilm formation of listeria monocytogenes strains under food processing environments and pan-genome-wide association study
2019
International audience; Concerns about food contamination by Listeria monocytogenes are on the rise with increasing consumption of ready-to-eat foods. Biofilm production of L. monocytogenes is presumed to be one of the ways that confer its increased resistance and persistence in the food chain. In this study, a collection of isolates from foods and food processing environments (FPEs) representing persistent, prevalent, and rarely detected genotypes was evaluated for biofilm forming capacities including adhesion and sessile biomass production under diverse environmental conditions. The quantity of sessile biomass varied according to growth conditions, lineage, serotype as well as genotype bu…

Genes, Ageing and Longevity in Humans: Problems, Advantages and Perspectives.
2006
Many epidemiological data indicate the presence of a strong familial component of longevity that is largely determined by genetics, and a number of possible associations between longevity and allelic variants of genes have been described. A breakthrough strategy to get insight into the genetics of longevity is the study of centenarians, the best example of successful ageing. We review the main results regarding nuclear genes as well as the mitochondrial genome, focusing on the investigations performed on Italian centenarians, compared to those from other countries. These studies produced interesting results on many putative "longevity genes". Nevertheless, many discrepancies are reported, l…
Morphological and genome-wide evidence for natural hybridisation within the genus Stipa (Poaceae)
2020
AbstractHybridisation in the wild between closely related species is a common mechanism of speciation in the plant kingdom and, in particular, in the grass family. Here we explore the potential for natural hybridisation in Stipa (one of the largest genera in Poaceae) between genetically distant species at their distribution edges in Mountains of Central Asia using integrative taxonomy. Our research highlights the applicability of classical morphological and genome reduction approaches in studies on wild plant species. The obtained results revealed a new nothospecies, Stipa × lazkovii, which exhibits intermediate characters to S. krylovii and S. bungeana. A high-density DArTseq assay disclos…
Transformacja Polskiego Związku Łowieckiego w świetle ewolucji modelu łowiectwa w Polsce
2020
The Polish Hunting Association is a nationwide organization of Polish hunters and hunting clubs, whose traditions date back to the interwar period. This study presents the genesis and evolution of the Polish Hunting Association, which, in the wake of social and political changes in the country, has been transformed from a voluntary association into a monopolistic and compulsory-membership organization, which is to carry out tasks commissioned by public authorities. Additionally, as a result of further amendments, the Association has been transformed into a governmental agency, organizationally subordinated to the minister of the environment also in the scope of appointing its high-rank staf…
Using virtual reality and mood-induction procedures to test products with consumers of ceramic tiles
2013
This work describes a Virtual Reality Environment (VRE), through which users are able to view and test ceramic tile products. Users' virtual interfacing with the products generated emotional experiences that allowed them to feel ''engaged'' with the products. Users could choose between different kinds of products and test them out in order to know how they would look in a real-world context. In the VRE several mood-induction Procedures for inducing relaxation were included. The VRE was tested with respect to its ability to induce relaxation and sense of presence in 26 participants. It was also analyzed the level of satisfaction. Measures included the Visual Analogue Scale, the Self-Assessme…
