Yeast-bacteria competition induced new metabolic traits through large-scale genomic rearrangements in Lachancea kluyveri
Large-scale chromosomal rearrangements are an important source of evolutionary novelty that may have reshaped the genomes of existing yeast species. They dramatically alter genome organization and gene expression fueling a phenotypic leap in response to environmental constraints. Although the emergence of such signatures of genetic diversity is thought to be associated with human exploitation of y
Large-scale evidence for the effect of the COLIA1 Sp1 polymorphism on osteoporosis outcomes : the GENOMOS study
BACKGROUND: Osteoporosis and fracture risk are considered to be under genetic control. Extensive work is being performed to identify the exact genetic variants that determine this risk. Previous work has suggested that a G/T polymorphism affecting an Sp1 binding site in the COLIA1 gene is a genetic marker for low bone mineral density (BMD) and osteoporotic fracture, but there have been no very-lar
Linkage disequilibrium between polymorphisms in the human TNFRSF1B gene and their association with bone mass in perimenopausal women
Osteoporosis is a multifactorial disease with a strong genetic component characterized by reduced bone density and increased fracture risk. A candidate locus for regulation of hip bone mineral density (BMD) has been identified on chromosome 1p36 by linkage analysis. One of the positional and functional candidate genes located within this region is the tumour necrosis factor receptor superfamily me
Genetic and environmental determinants of peak bone mass in young men and women
Peak bone mass is an important risk factor for the development of osteoporosis in later life. Previous work has suggested that genetic, intrauterine, and environmental factors all contribute to the regulation of bone mass, but the ways in which they interact with each other to do so remain poorly understood. In this study, we investigated the relationship between peak bone mass and polymorphisms o
Association between COLIA1 Sp1 alleles and femoral neck geometry
Genetic factors play an important role in the pathogenesis of osteoporosis by affecting bone mineral density and other predictors of osteoporotic fracture risk such as ultrasound properties of bone and skeletal geometry. We previously identified a polymorphism of a Sp1 binding site in the Collagen Type 1 Alpha 1 gene (COLIA1) that has been associated with reduced BMD and an increased risk of osteo
Trypanosoma brucei : mammalian epidermal growth factor promotes the growth of the African trypanosome bloodstream form
Vitamin K1 intake is associated with higher bone mineral density and reduced bone resorption in early postmenopausal Scottish women : no evidence of gene-nutrient interaction with apolipoprotein E polymorphisms
BACKGROUND: Polymorphisms in the apolipoprotein E (APOE) gene are associated with fracture risk, and a potential mechanism is through vitamin K transport.OBJECTIVE: We investigated the relation between dietary vitamin K(1) intake, APOE polymorphisms, and markers of bone health.DESIGN: We measured bone mineral density (BMD) at the lumbar spine (LS) and femoral neck (FN) in a cohort of Scottish wome
Large-scale population-based study shows no evidence of association between common polymorphism of the VDR gene and BMD in British women
UNLABELLED: The VDR is a candidate gene for osteoporosis. Here we studied five common polymorphisms of VDR in relation to calcium intake and vitamin D status in a population-based cohort of 3100 British women, but found no significant association with bone mass, bone loss, or fracture.INTRODUCTION: Population studies of vitamin D receptor (VDR) polymorphisms have produced conflicting results. We p
Methylenetetrahydrofolate reductase polymorphism interacts with riboflavin intake to influence bone mineral density
Bone mineral density is a complex trait regulated by an interaction between genetic and environmental factors. Recent studies have identified a functional polymorphism affecting codon 677 of the methylenetetrahydrofolate reductase (MTHFR) gene that is associated with reduced bone mineral density (BMD) in Japanese and Danish postmenopausal women and increased risk of fracture in elderly Danish wome
From passive passenger to participating co-pilot – Pregnant women's expectations of being able to access their online journal from antenatal care
Objective The aim of the study was to describe pregnant women's expectations of being able to access their electronic health records from antenatal care. Methods Nine pregnant women passing 25 full gestational weeks were interviewed individually. Collected data were analysed with an inductive approach using content analysis. The study was performed in antenatal care units in southern Sweden. Resul

Asymmetric semantic interaction in Jedek-Jahai bilinguals : Spatial language in a small-scale, non-standardized, egalitarian, long-term multilingual setting in Malaysia
Aims and objectives/purpose/research questions:We investigate semantic interaction in bilinguals’ topological relations descriptions in a small-scale, non-standardized, egalitarian, long-term multilingual setting in Malaysia.Design/methodology/approach:Two groups of bilingual speakers of Jedek and Jahai (8 Jedek-identifying, 6 Jahai-identifying bilinguals) and two groups of monolingual Jedek and J
VEGF synthesis is induced by prostacyclin and TGF-β in distal lung fibroblasts from COPD patients and control subjects : Implications for pulmonary vascular remodelling
Background and objective: Involvement of pulmonary vascular remodelling is a characteristic sign in COPD. Vascular mediators such as vascular endothelial growth factor (VEGF) and prostacyclin may regulate fibroblast activity. The objective was to study the synthesis of VEGF and interactions with prostacyclin and transforming growth factor (TGF)-β1 in lung fibroblasts from patients with COPD and he
Concentration on the few : mechanisms behind a falling share of innovative firms in Germany
Innovation activities in the German business sector showed two opposing trends over the past two decades: While total innovation expenditures grew substantially, the number of firms conducting innovation activities fell sharply. In this paper, we explore the mechanisms behind the declining trend in the share of innovation active firms. Considering both input (R&D activities) and output (introd
Detection of simultaneous multi-mutations using base-quenched probe
The base-quenched probe method for detecting single nucleotide polymorphisms (SNPs) relies on real-time PCR and melting-curve approaches. Here, we applied the most common commercial fluorophores including FAM, HEX, CY5, CY3, TET, JOE, Texas Red and ROX for labeling probes to detect multi-mutations simultaneously according to the different fluorescence channels. Accuracy of the method was confirmed
The ambulance nurse. Aspects on competence and education.
The knowledge area of ambulance nurses’ competence represents a relatively new research area that cannot be regarded as having been fully explored and described by existing research. There is uncertainty regarding the required competence for ambulance nurses as well as the professional role of the ambulance nurse in ambulance care. It is also not clear if the ambulance nurse educational programmes
ICP curve morphology and intracranial flow-volume changes : a simultaneous ICP and cine phase contrast MRI study in humans
Background: The intracranial pressure (ICP) curve with its different peaks has been extensively studied, but the exact physiological mechanisms behind its morphology are still not fully understood. Both intracranial volume change (ΔICV) and transmission of the arterial blood pressure have been proposed to shape the ICP curve. This study tested the hypothesis that the ICP curve correlates to intrac
