Neuronal traits are required for glucose-induced insulin secretion

Amar Abderrahmani, Guy Niederhauser, Valérie Plaisance, Jacques-Antoine Haefliger, Romano Regazzi, Gérard Waeber
2004 FEBS Letters  
The transcriptional repressor RE1 silencer transcription factor (REST) is an important factor that restricts some neuronal traits to neurons. Since these traits are also present in pancreatic b-cells, we evaluated their role by generating a model of insulin-secreting cells that express REST. The presence of REST led to a decrease in expression of its known target genes, whereas insulin expression and its cellular content were conserved. As a consequence of REST expression, the capacity to

Objective: To develop a composite patient safety score that provides patients, health-care providers, and health-care purchasers with a standardized method to evaluate patient safety in general acute care hospitals in the United States. Methods: The Leapfrog Group sought guidance from a panel of national patient safety experts to develop the composite score. Candidate patient safety performance measures for inclusion in the score were identified from publicly reported national sources. Hospital

A reference mean score was set at 3, with scores interpreted in terms of standard deviations above or below the mean, with above reflecting better than average performance. Results: Twenty-six measures were included in the score. The mean composite score for 2652 general acute care hospitals in the United States was 2.97 (range by hospital, 0.46Y3.94). Safety scores were slightly lower for hospitals that were publicly owned, rural in location, or had a larger percentage of patients with Medicaid as their primary insurance. Conclusions: The Leapfrog patient safety composite provides a standardized method to evaluate patient safety in general acute care hospitals in the United States. While constrained by available data and publicly reported scores on patient safety measures, the composite score reflects the best available evidence regarding a hospital's efforts and outcomes in patient safety. Additional analyses are needed, but the score did not seem to have a strong bias against hospitals with specific characteristics. The composite score will continue to be refined over time as measures of patient safety evolve. The coefficient of variation for the measure plus 1.0, capped at a maximum score of 3.0 reflects the variation in performance between hospitals. ‡ Measure of the number of patients possibly affected by the safety event and on the severity of harm for individual patients.

Architecture and characterization of a calibrator for PMUs operating in power distribution systems

Daniele Colangelo, Lorenzo Zanni, Marco Pignati, Paolo Romano, Mario Paolone, Jean-Pierre Braun, Laurent-Guy Bernier
2015 2015 IEEE Eindhoven PowerTech  
In recent years, the Phasor Measurement Unit (PMU) technology is rapidly evolving towards the potential deployment also in power distribution systems (DSs). In general, this specific field of applications requires PMUs whose accuracy levels are beyond those required by the IEEE Std. C37.118. Additionally, there is the need to define the architecture of an associated calibration system capable to assess the metrological performances of these devices. In this paper, we first analyse the impact of
more » ... the uncertainties (in term of phase and magnitude) introduced by arbitrary PMUs on a state estimation (SE) process performed on the IEEE 13-bus distribution test feeder. The outcomes of this analysis are used to infer the most stringent steady-state performances of PMUs for DSs monitoring and, consequently, to define the requirements and the hardware architecture of a PMU calibrator presently developed at the Author's laboratories. A preliminary metrological characterization of the proposed calibrator is presented in the paper.

The hairy and enhancer of split 1 is a negative regulator of the repressor element silencer transcription factor

Amar Abderrahmani, Guy Niederhauser, Vincent Lenain, Romano Regazzi, Gérard Waeber
2005 FEBS Letters  
Silencing of the transcriptional repressor REST is required for terminal differentiation of neuronal and b-cells. In this study, we hypothesized that REST expression is controlled by hairy and enhancer of split 1 (HES-1), a transcriptional repressor that plays an important role in brain and pancreas development. We identified several N elements (CTNGTG) within the promoter of REST and confirmed that HES-1 associates with the endogenous promoter of REST. Moreover, using a cells model that

2015 Diabetologia  
Aims/hypothesis Ageing can lead to reduced insulin sensitivity and loss of pancreatic beta cell function, predisposing individuals to the development of diabetes. The aim of this study was to assess the contribution of microRNAs (miRNAs) to age-associated beta cell dysfunction. Methods The global mRNA and miRNA profiles of 3-and 12-month-old rat islets were collected by microarray. The functional impact of age-associated differences in miRNA expression was investigated by mimicking the observed
more » ... changes in primary beta cells from young animals. Results Beta cells from 12-month-old rats retained normal insulin content and secretion, but failed to proliferate in response to mitotic stimuli. The islets of these animals displayed modifications at the level of several miRNAs, including upregulation of miR-34a, miR-124a and miR-383, and downregulation of miR-130b and miR-181a. Computational analysis of the transcriptomic modifications observed in the islets of 12-month-old rats revealed that the differentially expressed genes were enriched for miR-34a and miR-181a targets. Indeed, the induction of miR-34a and reduction of miR-181a in the islets of young animals mimicked the impaired beta cell proliferation observed in old animals. mRNA coding for alphatype platelet-derived growth factor receptor, which is critical for compensatory beta cell mass expansion, is directly inhibited by miR34a and is likely to be at least partly responsible for the effects of this miRNA. Conclusions/interpretation Changes in the level of specific miRNAs that occur during ageing affect the proliferative capacity of beta cells. This might reduce their ability to expand under conditions of increased insulin demand, favouring the development of type 2 diabetes.

2020 Environmental Epidemiology  
Behavioral effects of prenatal exposure to mixtures of essential and toxic metals are incompletely understood. We investigated neurodevelopmental effects of prenatal metal exposures in the New Hampshire Birth Cohort Study, a prospective birth cohort. We measured metals (As, Cu, Mn, Pb, Se, Zn) in maternal prenatal and postnatal toenails and infant toenails, reflecting exposures during periconception and early pregnancy, mid pregnancy, and late pregnancy and early neonatal life, respectively.

We used mean field variational Bayes for lagged kernel machine regression to investigate associations of toenail metal concentrations with SRS-2 Total Scores and BASC-2 composite scores (SRS-2: n = 371; BASC-2: n = 318). Infant toenail Mn was associated with poorer performance on multiple BASC-2 composite scores. Maternal postnatal toenail As was associated with worse scores on the BASC-2 Internalizing Problems and Behavioral Symptoms Index. Associations with Mn were generally stronger in males, and associations with As were generally stronger in females. Other metals, including Pb, were weakly or inconsistently associated with BASC-2 outcomes, and there were no strong associations of individual metals and SRS-2 Total Scores. We observed suggestive evidence of interaction between As and Se for SRS-2 Total Scores and BASC-2 Adaptive Skills, though overall evidence of interactions between metals was weak. Our results support the hypothesis that exposure to Mn and As in mid to late pregnancy may be neurodevelopmentally harmful.

Bariatric surgery is an effective treatment for type 2 diabetes. Early post-surgical enhancement of insulin secretion is key for diabetes remission. The full complement of mechanisms responsible for improved pancreatic beta cell functionality after bariatric surgery is still unclear. Our aim was to identify pathways, evident in the islet transcriptome, that characterize the adaptive response to bariatric surgery independently of body weight changes. We performed entero-gastro-anastomosis (EGA)

Multiple approaches such as determination of glucose tolerance, GLP-1 and insulin secretion, whole body insulin sensitivity, ex vivo glucose-stimulated insulin secretion (GSIS) and functional multicellular Ca2+-imaging, profiling of mRNA and of miRNA expression were utilized to identify significant biological processes involved in pancreatic islet recovery. EGA resolved diabetes, increased pancreatic insulin content and GSIS despite a persistent increase in fat mass, systemic and intra-islet inflammation, and lipotoxicity. Surgery differentially regulated 193 genes in the islet, most of which were involved in the regulation of glucose metabolism, insulin secretion, calcium signaling or beta cell viability, and these were normalized alongside changes in glucose metabolism, intracellular Ca2+ dynamics and the threshold for GSIS. Furthermore, 27 islet miRNAs were differentially regulated, four of them hubs in a miRNA-gene interaction network and four others part of a blood signature of diabetes resolution in ob/ob mice and in humans. Taken together, our data highlight novel miRNA-gene interactions in the pancreatic islet during the resolution of diabetes after bariatric surgery that form part of a blood signature of diabetes reversal.

The EIPonAHA is an interdisciplinary and cross-sector initiative involving more than 3000 partners with two specific objectives: to increase the healthy life expectancy of Europeans by two years by 2020, while increasing their QoL. The initiatives of the EIPonAHA have been organized according to six thematic action groups (AG), with the A3 group targeting areas relating to the prevention of functional decline and frailty. In addition to the good practices of partners, there are several on going collaborative works. The involvement of the EC includes support through an elaborated research programme in which the Consumers, Health, Agriculture and Food Executive Agency (CHAFEA) and the Directorate-General for Communications Networks, Content and Technology (DG CONNECT) are the main funding bodies. Screening approaches and preventive interventions constitute most of the initiatives within the A3 AG. Partners are distributed across five sub-groups according to good practices: i) cognitive decline, ii) food and nutrition, iii) physical activity, iv) caregivers, and v) frailty and functional decline. Regular updates of the progression of both good practices and collaborative works are presented in A3 AG meetings. The 2017 meeting in Valencia, Spain, showcased in this paper, provides an up-to-date overview of the current status of A3 activities.

Uncombable hair syndrome (UHS), also known as "spun glass hair syndrome," "pili trianguli et canaliculi," or "cheveux incoiffables" is a rare anomaly of the hair shaft that occurs in children and improves with age. UHS is characterized by dry, frizzy, spangly, and often fair hair that is resistant to being combed flat. Until now, both simplex and familial UHS-affected case subjects with autosomaldominant as well as -recessive inheritance have been reported. However, none of these case subjects

Here, we report the identification of UHS-causative mutations located in the three genes PADI3 (peptidylarginine deiminase 3), TGM3 (transglutaminase 3), and TCHH (trichohyalin) in a total of 11 children. All of these individuals carry homozygous or compound heterozygous mutations in one of these three genes, indicating an autosomal-recessive inheritance pattern in the majority of UHS case subjects. The two enzymes PADI3 and TGM3, responsible for posttranslational protein modifications, and their target structural protein TCHH are all involved in hair shaft formation. Elucidation of the molecular outcomes of the disease-causing mutations by cell culture experiments and tridimensional protein models demonstrated clear differences in the structural organization and activity of mutant and wild-type proteins. Scanning electron microscopy observations revealed morphological alterations in hair coat of Padi3 knockout mice. All together, these findings elucidate the molecular genetic causes of UHS and shed light on its pathophysiology and hair physiology in general.
