Maternal overnutrition programs hedonic and metabolic phenotypes across generations through sperm tsRNAs
2019
There is a growing body of evidence linking maternal overnutri-tion to obesity and psychopathology that can be conserved acrossmultiple generations. Recently, we demonstrated in a maternalhigh-fat diet (HFD; MHFD) mouse model that MHFD inducedenhanced hedonic behaviors and obesogenic phenotypes thatwere conserved across three generations via the paternal lineage,which was independent of sperm methylome changes. Here, weshow that sperm tRNA-derived small RNAs (tsRNAs) partly contrib-ute to the transmission of such phenotypes. We observe increasedexpression of sperm tsRNAs in the F1 male offspring born to HFD-exposed dams. Microinjection of sperm tsRNAs from the F1-HFDmale into normal zygotes…

Species-specific enamel differences in hardness and abrasion resistance between the permanent incisors of cattle (Bos primigenius taurus) and the eve…
2022
Hypselodont (ever-growing) teeth of lagomorphs or rodents have higher wear rates (of a magnitude of mm/week), with compensating growth rates, compared to the non-ever-growing teeth of ungulates (with a magnitude of mm/year). Whether this is due to a fundamental difference in enamel hardness has not been investigated so far. We prepared enamel samples (n = 120 per species) from incisors of cattle (Bos primigenius taurus) and nutria (Myocastor coypus, hypselodont incisors) taken at slaughterhouses, and submitted them to indentation hardness testing. Subsequently, samples were split into 4 groups per species (n = 24 per species and group) that were assessed for abrasion susceptibility by a sta…
The origin of failure: A multidisciplinary appraisal of the hubris hypothesis and proposed research agenda
2014
The hubris hypothesis complements the extant debate on how people make judgments and decisions in organizations. Drawing on the origin of hubris in Greek mythology, the psychological approach, and finance studies, this paper portrays an informed picture of the current status of managerial hubris literature that develops a more advanced understanding of what is known about hubris. We present a conceptual map that provides a comprehensive appreciation of hubris antecedents-symptoms-strategic choices-feedback performance main cause effect relationships. Our proposed conceptual map draws on the idea that managerial hubris is one of the determinants of CEO judgments, strategic choices, and organ…
Linear assembly of lead bromide-based nanoparticles inside lead(ii) polymers prepared by mixing the precursors of both the nanoparticle and the polym…
2019
Mixing precursors of lead(ii) polymers with those of lead bromide-based nanoparticles (CH3NH3PbBr3 perovskites or PbBr2), at room temperature and in the presence of cyclohexanemethylammonium bromide, generated colloidal nanocomposites which, when deposited on a hydrophobic surface led to long, one-dimensional, ordered and well-defined architectures. ispartof: CHEMICAL COMMUNICATIONS vol:55 issue:20 pages:2968-2971 ispartof: location:England status: published
Origin of the Chemiresistive Response of Ultrathin Films of Conductive Metal–Organic Frameworks
2018
Conductive metal-organic frameworks are opening new perspectives for the use of these porous materials for applications traditionally limited to more classical inorganic materials, such as their integration into electronic devices. This has enabled the development of chemiresistive sensors capable of transducing the presence of specific guests into an electrical response with good selectivity and sensitivity. By combining experimental data with computational modelling, a possible origin for the underlying mechanism of this phenomenon in ultrathin films (ca. 30 nm) of Cu-CAT-1 is described. ispartof: ANGEWANDTE CHEMIE-INTERNATIONAL EDITION vol:57 issue:46 pages:15086-15090 ispartof: location…
Controlling the mode of operation of organic transistors through side chain engineering
2016
Electrolyte-gated organic transistors offer low bias operation facilitated by direct contact of the transistor channel with an electrolyte. Their operation mode is generally defined by the dimensionality of charge transport, where a field-effect transistor allows for electrostatic charge accumulation at the electrolyte/semiconductor interface, whereas an organic electrochemical transistor (OECT) facilitates penetration of ions into the bulk of the channel, considered a slow process, leading to volumetric doping and electronic transport. Conducting polymer OECTs allow for fast switching and high currents through incorporation of excess, hygroscopic ionic phases, but operate in depletion mode…
Programmable assembly of peptide amphiphile via noncovalent-to-covalent bond conversion
2017
Controlling the number of monomers in a supramolecular polymer has been a great challenge in programmable self-assembly of organic molecules. One approach has been to make use of frustrated growth of the supramolecular assembly by tuning the balance of attractive and repulsive intermolecular forces. We report here on the use of covalent bond formation among monomers, compensating for intermolecular electrostatic repulsion, as a mechanism to control the length of a supramolecular nanofiber formed by self-assembly of peptide amphiphiles. Circular dichroism spectroscopy in combination with dynamic light scattering, size-exclusion chromatography, and transmittance electron microscope analyses r…
A Patient Registry to Improve Patient Safety: Recording General Neurosurgery Complications
2016
Background To improve the transparency of the local health care system, treatment cost was recently referenced to disease related groups. Treatment quality must be legally documented in a patient registry, in particular for the highly specialized treatments provided by neurosurgery departments. Methods In 2013 we have installed a patient registry focused on cranial neurosurgery. Surgeries are characterized by indication, treatment, location and other specific neurosurgical parameters. Preoperative state and postoperative outcome are recorded prospectively using neurological and sociological scales. Complications are graded by their severity in a therapy-oriented complication score system (C…
Adolescent boys with asthma – a pilot study on embodied gendered habits
2012
Thomas Westergren,1 Ulla-Britt Lilleaas21Faculty of Health and Sport Science, Department of Health and Nursing Science, University of Agder, Grimstad, Norway; 2Faculty of Humanities and Education, Centre for Gender and Equality, University of Agder, Kristiansand, NorwayPurpose: Asthma is a common chronic disease with gender differences in terms of severity and quality of life. This study aimed to understand the gendered practices of male asthmatic adolescents in terms of living with and managing their chronic disease. The study applied a sociological perspective to identify the gender-related practices of participants and their possible consequences for health and disease.Patients and metho…
