Role of Stro1+/CD44+ stem cells in myometrial physiology and uterine remodeling during pregnancy†
2016
Regulation of myometrial functions during pregnancy has been considered the result of the integration of endocrine and mechanical signals. Nevertheless, uterine regeneration is poorly understood, and the cellular source within the gravid uterus is largely unexplored.In this study, we isolated and quantified the myometrial stem cells (MSC) population from pregnant female Eker rat uteri, by using Stro1/CD44 surface markers. We demonstrated that prior parity significantly increased the percentage of Stro1+/CD44+ MSC because of injured tissue response. Interestingly, we established that Stro1+/CD44+ MSC respond efficiently to physiological cues when they were treated in vitro under different do…
Sex-Specific Genetic Effects Associated with Pigmentation, Sensitivity to Sunlight, And Melanoma in a Population of Spanish Origin
2016
Background Human pigmentation is a polygenic quantitative trait with high heritability. In addition to genetic factors, it has been shown that pigmentation can be modulated by oestrogens and androgens via up- or down-regulation of melanin synthesis. Our aim was to identify possible sex differences in pigmentation phenotype as well as in melanoma association in a melanoma case-control population of Spanish origin. Methods Five hundred and ninety-nine females (316 melanoma cases and 283 controls) and 458 males (234 melanoma cases and 224 controls) were analysed. We genotyped 363 polymorphisms (single nucleotide polymorphisms (SNPs)) from 65 pigmentation gene regions. Results When samples were…
The Intracellular Cleavage Product of the NG2 Proteoglycan Modulates Translation and Cell-Cycle Kinetics via Effects on mTORC1/FMRP Signaling
2018
The NG2 proteoglycan is expressed by oligodendrocyte precursor cells (OPCs) and is abundantly expressed by tumors such as melanoma and glioblastoma. Functions of NG2 include an influence on proliferation, migration and neuromodulation. Similar to other type-1 membrane proteins, NG2 undergoes proteolysis, generating a large ectodomain, a C-terminal fragment (CTF) and an intracellular domain (ICD) via sequential action of α- and γ-secretases which is enhanced by neuronal activity. Functional roles of NG2 have so far been shown for the full-length protein, the released ectodomain and CTF, but not for the ICD. In this study, we characterized the role of the NG2 ICD in OPC and Human Embryonic Ki…
Violent offending in borderline personality disorder and attention deficit/hyperactivity disorder.
2018
Abstract The prevalence of borderline personality disorder (BPD) and attention deficit/hyperactivity disorder (ADHD) is significantly higher among offenders compared to the prevalence found in the general population. Both disorders share important diagnostic characteristics and thus it has been suggested that they might follow a common developmental pathway. In this narrative review, we first discuss the potential links of disorder inherent symptoms such as impulsivity and emotion regulation difficulties and how they might elevate the risk of violent delinquency. We continue with highlighting that comorbidities particularly from the antisocial spectrum as well as comorbid substance use diso…
Characterisation of microsatellite and SNP markers from Miseq and genotyping-by-sequencing data among parapatric Urophora cardui (Tephritidae) popula…
2017
Phylogeographic analyses of the gall flyUrophora carduihave in earlier studies based on allozymes and mtDNA identified small-scale, parapatrically diverged populations within an expanding Western Palearctic population. However, the low polymorphism of these markers prohibited an accurate delimitation of the evolutionary origin of the parapatric divergence.Urophora carduifrom the Western Palearctic have been introduced into Canada as biological control agents of the host plantCirsium arvense. Here, we characterise 12 microsatellite loci with hexa-, penta- and tetra-nucleotide repeat motifs and report a genotyping-by-sequencing SNP protocol. We test the markers for genetic variation among thr…
Understanding illnesses through a film festival: an observational study
2019
Abstract Audio-visual materials play a fundamental role in the context of education, care and clinical treatment, as they seem to have a high impact on public awareness. This study aims to describe what messages are perceived by the society at an International Festival of Short Films and Art on Diseases that may help to understand difficult topics, such as illness, dying and suffering. Through an observational, descriptive, cross-sectional study, using full participant observation and an open, self-administered questionnaire, 32 short films were analysed during a healthcare art festival. Categories were developed using inductive content analysis. The message perceived by the participants, a…
Predictive validity of the risk SCORE model in a Mediterranean population with dyslipidemia.
2019
Background and aims: Cholesterol treatment for the primary prevention of cardiovascular disease is based on cardiovascular risk, as assessed by the SCORE (Systematic COronary Risk Evaluation) scale. This study aimed to assess the predictive value and clinical utility of the SCORE scale for preventing cardiovascular events and all-cause mortality in people with dyslipidemia and no lipid-lowering treatment. Methods: Patients with dyslipidemia and no lipid-lowering treatment were included from the ESCARVAL-RISK cohort. Cardiovascular risk was calculated by means of the SCORE scale. All deaths and cardiovascular events were recorded for up to five years of follow-up. We calculated sensitivity, …
Association between familial hypobetalipoproteinemia and the risk of diabetes. Is this the other side of the cholesterol-diabetes connection? A syste…
2017
Statin therapy is beneficial in reducing LDL cholesterol (LDL-C) levels and cardiovascular events, but it is associated with the risk of incident diabetes mellitus (DM). Familial hypercholesterolemia (FH) is characterized by genetically determined high levels of plasma LDL-C and a low prevalence of DM. LDL-C levels seem then inversely correlated with prevalence of DM. Familial hypobetalipoproteinemia (FHBL) represents the genetic mirror of FH in terms of LDL-C levels, very low in subjects carrying mutations of APOB, PCSK9 (FHBL1) or ANGPTL3 (FHBL2). This review explores the hypothesis that FHBL might represent also the genetic mirror of FH in terms of prevalence of DM and that it is expecte…
How to deal with context? A context-mapping tool for quality and safety in nursing homes and homecare (SAFE-LEAD Context)
2019
Abstract Objective The objective of this paper is to develop a context-mapping tool (SAFE-LEAD Context) adapted to the nursing home and homecare setting. These two contexts represent a substantial variability, but studies focusing on the types and roles of contextual factors in quality and safety in these care settings are lacking. Results We conducted a step-wise collaborative design process consisting of mapping of key contextual factors as perceived by managers in Norwegian nursing homes and homecare, then created a draft tool discussed in a consortium workshop with co-researchers, and ran an international cross-country comparison. The SAFE-LEAD Context tool is inspired by the Consolidat…
Neurotoxicity of zearalenone’s metabolites and beauvericin mycotoxins via apoptosis and cell cycle disruption
2021
Cell cycle progression and programmed cell death are imposed by pathological stimuli of extrinsic or intrinsic including the exposure to neurotoxins, oxidative stress and DNA damage. All can cause abrupt or delayed cell death, inactivate normal cell survival or cell death networks. Nevertheless, the mechanisms of the neuronal cell death are unresolved. One of the cell deaths triggers which have been wildly studied, correspond to mycotoxins produced by Fusarium species, which have been demonstrated cytotoxicity and neurotoxicity through impairing cell proliferation, gene expression and induction of oxidative stress. The aim of present study was to analyze the cell cycle progression and cell …
