A prospective analysis of islet-cell cytotoxic antibodies in insulin-dependent diabetic children. Transient effects of plasmapheresis
We determined the effects of plasmapheresis on cytotoxic antibodies to islet cells in 10 children (aged 11-16 yr) with newly diagnosed insulin-dependent diabetes mellitus (IDDM), as well as the plasma levels of antibodies over the next 30 mo and their relation to serum C-peptide concentrations. Complement-dependent, antibody-mediated cytotoxicity (C'AMC) in plasma was measured in a 51Cr release as
In vitro lymphocyte recognition of islet cells following in vivo priming with allogeneic murine pancreatic islets
Lymphocytes from patients with insulin-dependent diabetes have been shown to be sensitized to pancreatic tissue antigens. Mice immunized with homologous pancreatic islets have been found to develop glucose intolerance and insulitis. Since lymphocytes may be involved in diabetogenesis, we wished to determine if lymph node cells from islet-immunized mice can recognize and respond to islet cells in v
Islet cell surface and lymphocyte antibodies often precede the spontaneous diabetes in the BB rat
The diabetic syndrome of the BB rat shows many homologies with that of human insulin-dependent diabetes and evidence that the onset of the disease is associated with the presence of autoantibodies, including islet cell surface antibodies. In this study, sera were sampled serially from weaning to 157 days of age from 26 BB rats in two low-incidence litters, and 22 rats of three high-incidence litte
Why Low Levels of Democracy Promote Corruption and High Levels Diminish It
Theory predicts democracy should reduce corruption. Yet, scholars have found that while corruption is low at high levels of democracy, it is high at modest levels, as well as low when democracy is absent. A weakness of studies that aim to explain this inverted curvilinear relationship is that they do not disaggregate the complex concepts of democracy and corruption. By contrast, this paper disaggr
Features of urine S100B and its ability to rule out intracranial hemorrhage in patients with head trauma : a prospective trial
Purpose: Traumatic brain injury causes morbidity and mortality worldwide. S100B is the most documented emergency brain biomarker and its urine-assay might be advantageous because of easier sampling. The primary aim was to evaluate urine S100B’s ability to rule out intracranial hemorrhage. Secondary aims included S100B temporal pattern for 48 h post-trauma and chemical properties of urine that affe
Explaining the measurement and evaluation stasis : A thought experiment and a note on functional stupidity
Purpose: The purpose of this paper is to explain the “evaluation deadlock” or “stasis” diagnosed by many authors. The explanation relies on a thought experiment. Design/methodology/approach: The paper is conceptual and builds on a thought experiment inspired by qualitative research such as interviews with communication consultants in Sweden. It makes use of principal–agent theory and Akerlof’s the
Ship Generated Waves Over a Complex Bathymetry

Intimate partner violence and maternal depression during pregnancy : A community-based cross-sectional study in Ethiopia
Introduction Intimate partner violence (IPV) is regarded an important public health and human rights issue, characterized by physical, sexual or emotional abuse. Globally more than one in three women report physical or sexual violence by their intimate partners. Though the association between IPV and depression is known, we found no study investigating depression as a risk factor for IPV and very
Water Resources Management Through Flood Spreading Project Suitability Mapping Using Frequency Ratio, k-nearest Neighbours, and Random Forest Algorithms
Lack of water resources is a common issue in many countries, especially in the Middle East. Flood spreading project (FSP) is an artificial recharge technique, which is generally suggested for arid and semi-arid areas with two major aims including (1) flood mitigation and (2) artificial recharge of groundwater. This study implemented three state-of-the-art popular models including frequency ratio (
Application of alkylresorcinols in an organic apple orchard for protection against storage diseases
Each year, fungal storage diseases destroy large amounts of apple, especially in organic orchards. In the present study, antifungal activity of a rye bran-based remedy with 5-n-alkylresorcinols (ARs) was investigated. In 2014 and 2015, ‘Amorosa’ apple trees in an organic orchard were sprayed with a 0.025% AR emulsion pre-harvest, once or twice at different points in time. In addition, emulsions wi
Year-round distribution, activity patterns and habitat use of a poorly studied pelagic seabird, the fluttering shearwater Puffinus gavia
We present the first study to examine the year-round distribution, activity patterns, and habitat use of one of New Zealand’s most common seabirds, the fluttering shearwater (Puffinus gavia). Seven adults from Burgess Island, in the Hauraki Gulf, and one individual from Long Island, in the Marlborough Sounds, were successfully tracked with combined light-saltwater immersion loggers for one to thre
Split N and P addition decreases straw mineralization and the priming effect of a paddy soil : a 100-day incubation experiment
The effect of mineral fertilization and its application pattern on microbial activity and the subsequent CO2 and CH4 emissions arising from soil organic matter (SOM) or added substrate remains unclear. We quantified the decomposition of 13C-labeled straw and the priming effect (PE) governed by the N and P fertilizer application pattern during a 100-day experiment in a flooded soil. Straw addition
Driving Neuronal Differentiation through Reversal of an ERK1/2-miR-124-SOX9 Axis Abrogates Glioblastoma Aggressiveness
Identifying cellular programs that drive cancers to be stem-like and treatment resistant is critical to improving outcomes in patients. Here, we demonstrate that constitutive extracellular signal-regulated kinase 1/2 (ERK1/2) activation sustains a stem-like state in glioblastoma (GBM), the most common primary malignant brain tumor. Pharmacological inhibition of ERK1/2 activation restores neurogene
Impact of menstrual function on hormonal response to repeated bouts of intense exercise
Background: Strenous exercise stimulates the hypothalamic-pituitary (HP) axis in order to ensure homeostasis and promote anabolism. Furthermore, exercise stimulates a transient increase in the neurotrophin brain-derived neurotrophic factor (BDNF) suggested to mediate the anxiolytic effects of exercise. Athletes with secondary functional hypothalamic amenorrhea (FHA) have been reported to have lowe
B cell profiling in malaria reveals expansion and remodeling of CD11c+ B cell subsets
Humoral immunity is important in limiting clinical disease in malaria, yet the longitudinal B cell response to infection remains unclear. We performed a 1-year prospective study in patients treated for acute Plasmodium falciparum malaria for the first time or with previous exposure to the disease. Using an unbiased exploratory approach with mass cytometry, followed by targeted flow cytometry, we f
Spectroscopy of kaonic atoms at DAFNE and J-PARC
The interaction of antikaons (K) with nucleons and nuclei in the low-energy regime represents a very active research field in hadron physics. A unique and rather direct experimental access to the antikaon-nucleon scattering lengths is provided by precision X-ray spectroscopy of transitions in low-lying states in the lightest kaonic atoms (i.e. kaonic hydrogen and deuterium). In the SIDDHARTA exper
Evolutionary aspects of Indo-European gender assignment
Gender assignment in languages with a gender system is a complex issue, as this can be influenced by both semantic, morphological, and phonological factors (Corbett, 1991, 2013; Corbett & Fraser, 2000). Many Indo-European languages possess a three-gender system, which distinguishes masculine, feminine, and neuter gender. Whereas this system is preserved in several Indo-European branches, it ha
TANGO2 deficiency as a cause of neurodevelopmental delay with indirect effects on mitochondrial energy metabolism
Exome sequencing has recently identified mutations in the gene TANGO2 (transport and Golgi organization 2) as a cause of developmental delay associated with recurrent crises involving rhabdomyolysis, cardiac arrhythmias, and metabolic derangements. The disease is not well understood, in part as the cellular function and subcellular localization of the TANGO2 protein remain unknown. Furthermore, th
