Herglotz functions and applications in electromagnetics

Herglotz functions inevitably appear in pure mathematics, mathematical physics, and engineering with a wide range of applications. In particular, they are the pertinent functions to model passive systems, and thus appear in modeling of electromagnetic phenomena in circuits, antennas, materials, and scattering. In this chapter, we review the basic theory of Herglotz functions and its applications t

Predictive value of islet cell and insulin autoantibodies for type 1 (insulin-dependent) diabetes mellitus in a population-based study of newly-diagnosed diabetic and matched control children

Most studies evaluating immune markers for prediction of Type 1 (insulin-dependent) diabetes mellitus have focused on first degree relatives, although only 10% of newly-diagnosed patients have an affected first degree relative. The Swedish Childhood Diabetes Register identifies 99% of all diabetic children at diagnosis. In this population-based study, islet cell antibodies and insulin autoantibodi

Enabling social participation for older people : The content of reablement by age, gender, and level of functioning in occupational therapists’ interventions

Background: Social participation and the ability to build and maintain social relationships is emphasized as important for older people’s health and well-being. Aim: To explore if social participation is addressed and whether age, gender and level of functioning are associated with the composition of occupational therapy interventions within the context of reablement. Method: In this cross-section

Matching on action : Effects of action speed and viewpoint on perceived continuity across match-action film edits

A match-action cut in feature films connects two shots of a single continuous movement. This type of editing often goes unnoticed and is arguably the most effective form of continuity editing. However, the literature offers little agreement on editing best practice and, by implication, on how our perceptual system deals with disjointed moving images. Studies have suggested that frames should overl

Long-term tolerability and efficacy after initial PegIFN-α addition to dasatinib in CML-CP : Five-year follow-up of the NordCML007 study

Objectives: Treatment-free remission (TFR) has emerged as a treatment goal in chronic myeloid leukemia in the chronic phase (CML-CP). Attempts to increase proportion of patients achieving TFR include combination of tyrosine kinase inhibitors (TKI) and other drugs. Interferon-α in addition to TKI has shown promising efficacy but with dose-dependent toxicity and discontinuations. NordCML007 was init

Regulation of glutamic acid decarboxylase diabetes autoantigen expression in highly purified isolated islets from Macaca nemestrina

Macaca nemestrina, which may have larger and more numerous pancreatic islets than other species, was used for large scale islet isolation by ductal collagenase perfusion and Ficoll gradient centrifugation. The average yield was 51,000 islet equivalents per pancreas, or 8,750 islets equivalents per g. The average purity was 91%, often exceeding 95%. These are the highest reported size, purity, and

A report on influences from superfluid turbulence in Der Rufer for percussion quartet

This report will discuss the influence of research into superfluid turbulence on my composition Der Rufer for percussion quartet. Written for Professor Olaf Tzschoppe, director of the Bremen Percussion Quartet, this work is the first result of a planned long-term collaboration with J.G. Weisend II, a Deputy Head of Accelerator Projects at the European Spallation Source (E.S.S.).

High level of concordance between assays for glutamic acid decarboxylase antibodies : The First International Glutamic Acid Decarboxylase Antibody Workshop

Glutamic acid decarboxylase antibodies (GADAbs) are being increasingly used in clinical and research programs for the prediction and classification of insulin-dependent diabetes mellitus (IDDM). A number of different assay formats for the measurement of GADAbs have been reported, but the degree of concordance between assays is unknown. In this study, GADAbs were measured on 16 coded sera in 34 ass

The Alterations of Mitochondrial Function during NAFLD Progression : An Independent Effect of Mitochondrial ROS Production

The progression of non-alcoholic fatty liver (NAFL) into non-alcoholic steatohepatitis implicates multiple mechanisms, chief of which is mitochondrial dysfunction. However, the sequence of events underlying mitochondrial failure are still poorly clarified. In this work, male C57BL/6J mice were fed with a high-fat plus high-sucrose diet for 16, 20, 22, and 24 weeks to induce NAFL. Up to the 20th we

A mitochondria-targeted caffeic acid derivative reverts cellular and mitochondrial defects in human skin fibroblasts from male sporadic Parkinson's disease patients

Parkinson's Disease (PD) is a neurodegenerative disorder affecting more than 10 million people worldwide. Currently, PD has no cure and no early diagnostics methods exist. Mitochondrial dysfunction is presented in the early stages of PD, and it is considered an important pathophysiology component. We have previously developed mitochondria-targeted hydroxycinnamic acid derivatives, presenting antio

Nanotechnology as a therapeutic strategy to prevent neuropsychomotor alterations associated with hypercholesterolemia

Hypercholesterolemia has been linked to neurodegenerative disease development. Previously others and we demonstrated that high levels of plasma cholesterol-induced memory impairments and depressive-like behavior in mice. More recently, some evidence reported that a hypercholesterolemic diet led to motor alterations in rodents. Peripheral inflammation, blood-brain barrier (BBB) dysfunction, and neu

Subcellular localization of sphingosine 1-phosphate receptors in synapses of the mouse cortex

Sphingosine 1-phosphate (S1P) has pleiotropic biological functions in the regulation of proliferation, survival, migration, inflammation or angiogenesis. S1P acts as intracellular second messenger, as well as extracellular receptor ligand via five G-protein coupled receptors (S1PR1-5). In the brain, S1P regulates neuronal proliferation or apoptosis, excitatory neurotransmission and neuroglia activ

Exploratory Data Analysis of Cell and Mitochondrial High-Fat, High-Sugar Toxicity on Human HepG2 Cells

Non-alcoholic steatohepatitis (NASH), one of the deleterious stages of non-alcoholic fatty liver disease, remains a significant cause of liver-related morbidity and mortality worldwide. In the current work, we used an exploratory data analysis to investigate time-dependent cellular and mitochondrial effects of different supra-physiological fatty acids (FA) overload strategies, in the presence or a

Afrostyrax lepidophyllus Mildbr. and Monodora myristica (Gaertn.) Dunal Extracts Decrease Doxorubicin Cytotoxicity on H9c2 Cardiomyoblasts

Materials and Methods: Bark extracts of these plants (1 and 25 µg/mL) were added 3 hours before coincubating H9c2 cardiomyoblasts with Dox (0.5 and 1 µM) for 24 hours more. We measured cell mass and metabolic viability, mitochondrial transmembrane potential, superoxide anion content, and activity-like of caspase-3 and caspase-9 following treatment with the extracts and/or Dox. Also, selenium and v

Refinement of a differentiation protocol using neuroblastoma SH-SY5Y cells for use in neurotoxicology research

Since most models used to study neuronal dysfunction display disadvantages and ethical concerns, a fast and reproducible in vitro model to study mitochondria-related neurodegeneration is required. Here, we optimized and characterized a 3-day retinoic acid-based protocol to differentiate the SH-SY5Y cell line into a neuronal-like phenotype and investigated alterations in mitochondrial physiology an

Taurine and N-acetyl-cysteine supplementation prevents memory impairment in high-fat diet-fed female mice

Background: The risk to develop memory impairment in has been widely investigated in type 2 diabetes (T2D). There are several mechanisms proposed for T2D-associated cognitive impairment, such as brain insulin resistance, synaptic dysfunction, inflammation, gliosis, or disruption of neuron-astrocyte interactions (Garcia-Serrano & Duarte, 2020). On the other hand, supplementation with the antiox
