Genome-wide association studies identify four ER negative-specific breast cancer risk loci

2013

Estrogen receptor (ER)-negative tumors represent 20-30% of all breast cancers, with a higher proportion occurring in younger women and women of African ancestry. The etiology and clinical behavior of ER-negative tumors are different from those of tumors expressing ER (ER positive), including differences in genetic predisposition. To identify susceptibility loci specific to ER-negative disease, we combined in a metaanalysis 3 genome-wide association studies of 4,193 ER-negative breast cancer cases and 35,194 controls with a series of 40 follow-up studies (6,514 cases and 41,455 controls), genotyped using a custom Illumina array, iCOGS, developed by the Collaborative Oncological Gene-environm…

The love of money and work‐related attitudes

2004

This study examines the love of money and work‐related attitudes and identifies four money profiles based on a sample of citizens in the Republic of Macedonia. Achieving Money Worshipers (the highest scores on Factors Success, Motivator, and Budget and the lowest on Evil) had the highest active involvement in work activities. Careless Money Admirers (the lowest score on Factor Budget) had the highest external locus of control, the highest involvement, and lowest success avoidance. Apathetic Money Managers (the lowest scores on Factors Success and Motivator) had the highest internal locus of control and the lowest involvement. Money Repellent Individuals (the highest score on Factor Evil) ha…

Fragmentation-related patterns of genetic differentiation in pedunculate oak (Quercus robur) at two hierarchical scales

2016

Populations at species' range margins are expected to show lower genetic diversity than populations at the core of the range. Yet, long-lived, widespread tree species are expected to be resistant to genetic impoverishment, thus showing comparatively high genetic diversity within populations and low differentiation among populations. Here, we study the distribution of genetic variation in the pedunculate oak (Quercus robur L.) at its range margin in Finland at two hierarchical scales using 15 microsatellite loci. At a regional scale, we compared variation within versus among three oak populations. At a landscape scale, we examined genetic structuring within one of these populations, growing …

Retama species growing in different ecological-climatic areas of northeastern Algeria have a narrow range of rhizobia that form a novel phylogenetic …

2009

International audience; Sixty-seven isolates were isolated from nodules collected on roots of Mediterranean shrubby legumes Retama raetam and Retama sphaerocarpa growing in seven ecological-climatic areas of northeastern Algeria. Genetic diversity of the Retama isolates was analyzed based on genotyping by restriction fragment length polymorphism of PCR-amplified fragments of the 16S rRNA gene, the intergenic spacer (IGS) region between the 16S and 23S rRNA genes (IGS), and the symbiotic genes nifH and nodC. Eleven haplotypes assigned to the Bradyrhizobium genus were identified. Significant biogeographical differentiation of the rhizobial populations was found, but one haplotype was predomin…

“Phraseological fossils”: morphology of "fossil words" as idiomatic words in Spanish idioms

2020

[ES] En el presente trabajo pretendemos ofrecer un análisis de la configuración formal del tipo de palabras idiomáticas que denominamos “fósiles fraseológicos”. Para ello, tras delimitar los conceptos de “palabra idiomática” y “fósil fraseológico”, se aclaran los procedimientos metodológicos para recopilar este tipo de voces en un diccionario general actual como el DLE, y se procede al análisis del corpus obtenido. El principal rasgo de los fósiles fraseológicos es que presentan los cambios evolutivos característicos de la evolución del latín al español, como voces patrimoniales que son. [EN] The objective of this paper is to offer an analysis of the morphology of the kind of idiomatic word…

Molecular phylogeny of Old World swifts (Aves: Apodiformes, Apodidae, Apus and Tachymarptis) based on mitochondrial and nuclear markers.

2011

We provide a molecular phylogeny for Old World swifts of genera Apus and Tachymarptis (tribe Apodini) based on a taxon-complete sampling at the species level. Phylogenetic reconstructions were based on two mitochondrial (cytochrome b, 12S rRNA) and three nuclear markers (introns of fibrinogen and glyceraldehyde 3-phosphate dehydrogenase plus anonymous marker 12884) while the myoglobin intron 2 did not show any intergeneric variation or phylogenetic signal among the target taxa at all. In contrast to previous hypotheses, the two genera Apus and Tachymarptis were shown as reciprocally monophyletic in all reconstructions. Apus was consistently divided into three major clades: (1) East Asian cl…

Characterization of Colletotrichum strains associated with olive anthracnose in Sicily

2022

Anthracnose caused by Colletotrichum spp. is the most damaging olive fruit disease in many countries, including Italy. This disease has been sporadically detected in Sicily, but new agronomic practices can increase risk of olive anthracnose in this region. An etiological study of the disease focused on local olive cultivars growing at the International Olive Germplasm Collection (IOGC) in Villa Zagaria, Enna, Sicily has been undertaken. During 2018 and 2019, 137 Colletotrichum strains were isolated from olives. Colony morphology, conidium characteristics, and multilocus sequence analyses aided identification of three species: C. acutatum (affecting 70% of symptomatic olives), C. gloeosporio…

Early-onset ataxia with cardiomyopathy and retained tendon reflexes maps to the friedreich's ataxia locus on chromosome 9q

1995

Absence of lower limb tendon reflexes has been considered an essential diagnostic criterion for Friedreich's ataxia (FA). However, preservation of knee and ankle jerks has been reported in a few patients. Linkage analysis to FA locus (FRDA) on chromosome 9q13-21.1 was performed in 11 patients from 6 families with FA phenotype, including cardiomyopathy, but retained reflexes (FARR). A maximal lod score of 3.38 at recombination fraction theta equal to 0.00 was obtained demonstrating that FARR maps to the FRDA locus. These results suggest that FARR is a variant phenotype of FA.
