Genome-wide scan of fat-tail sheep identifies signals of selection for fat deposition and adaptation
2018
Fat tail in sheep represents a valuable energy reserve for facing future climate changes. The identification of genes with a role in the fat-tail phenotype may contribute to understanding the physiology of fat deposition and the mechanisms of adaptation. Genotypic data obtained with the OvineSNP50K array in 13 thin-tail sheep breeds from Italy were used to identify selection signatures of fat tail through pairwise thin- versus fat-tail sheep breed comparisons, with the following fat-tail breeds of the Mediterranean area: two unique Italian fat-tail breeds (Barbaresca and Laticauda), a Barbary sheep breed from Libya, Ossimi breed from Egypt, Cyprus Fat-Tail and Chios from the Greek islands …
New insights on water buffalo genomic diversity and post-domestication migration routes from medium density SNP chip data
2018
Made available in DSpace on 2018-12-11T16:52:11Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-03-02 The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil were genotyped with a species-specific medium-dens…

Nature is an indispensable source of new drugs, providing unique bioactive lead structures for drug discovery. In the present study, secalonic acid F (SAF), a naturally occurring ergochrome pigment, was studied for its cytotoxicity against various leukemia and multiple myeloma cells by the resazurin assay. SAF exhibited cytotoxic activity on both leukemia and multiple myeloma cells. Generally, multiple myeloma cells were more sensitive to SAF than leukemia cells. NCI-H929 cells were the most affected cells among the tested panel of multiple myeloma cell lines and were taken for further studies to assess the mode of action of SAF on those cells. Cell cycle analysis revealed that SAF induced …

A substantial body of research has shown worse health conditions for East- vs. West-Germany in the wake of reunification. In the present study, we investigate how these differences between the two formerly divided regions developed and what maintains them. Specifically, we consider the associations between health status, income satisfaction, and health-related locus of control. In a quasi-experimental and longitudinal study design, we are particularly interested in the differences between individuals who stayed in East-Germany and those who were born in the East but migrated to West-Germany. To this end, we examined data from seven waves of the Saxony Longitudinal Study (2003–2009). Specifi…
Molecular characterisation of k-casein gene in Girgentana dairy goat breed and identification of two new alleles
2015
The k-casein fraction plays an important role in the formation, stabilisation and aggregation on casein micelles and thus affects technological and nutritional properties of milk. In this study, exon 4 of k-casein (CSN3) gene was sequenced and analysed in Girgentana goat breed. Analyses of the obtained sequences showed the presence of A, B, D, and G known alleles and two new genetic variants, named D’ and N. The new D’ allele differs from D in one transition, G284→A284, which did not cause amino acid change. The new N allele differs from A in five single nucleotide polymorphisms (SNPs): T245/C245, G284/A284, G309/A309, G471/A471 and T591/C591, while it differs from C in one transition, i.e.…
Remittance behaviours of foreigners in Italy
2015
This article investigates the determinants of remittance behaviours among foreigners in Italy and intends to gain a better understanding of the temporal pattern of remittances. The analysis is based on data from the 2009 “Italian Statistics on Income and Living Conditions of Households with Foreigners”. The decisions on whether to remit and how much to remit are separately yet simultaneously estimated using a zero-inflated beta regression model. The findings reveal that remittances are driven by a mix of altruistic and self-interest motives that may persist for many years. Many covariates included in the model have a different effect on the propensity to remit and on the relative amount of …
Le sentiment de discrimination des descendants d'immigrés : reflet d'une orientation contrariée et d'un chômage persistant
2012
National audience; La discrimination est analysée ici en croisant les perceptions des jeunes avec la réalité de leur insertion sur le marché du travail et de leur parcours d'éducation. Une orientation contrariée en fin de troisième a un impact sur les trajectoires ultérieures, comme l'obtention d'un emploi. Certes, le chômage est lié au niveau d'études, mais les descendants d'immigrés originaires du Maghreb ou d'Afrique subsaharienne y sont surexposés, mettant en relief une discrimination à l'embauche, discrimination vivement ressentie par les jeunes eux-mêmes.
Attempts for Common Understanding of the Concept of Worker as a Consequence of Globalisation?
2017
AbstractGlobalisation may concern many different issues, among others, the increase in migration that creates opportunities for all. There should be no doubt that globalisation can bring both positive and negative effects to workers. It can be seen as new opportunities for people, because they can travel, work, learn and live in different countries. Simultaneously however it can be perceived as synonymous to job losses, social injustice, or low environmental, health, and privacy standards. As a result of globalisation, the world is becoming more and more complex and the economic importance of state borders is reduced. It should therefore not raise doubts, that global problems require the ca…
