Background: Relapse of disease is frequent in anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV). It is unclear whether persistent ANCA when starting maintenance therapy increases the risk of relapse. We examined the association between ANCA status and relapse in two randomised controlled trials. Methods: ANCA-positive patients in two trials, CYCLOPS and IMPROVE, were switched f
INTRODUCTION: It is hypothesized that cerebral hypoperfusion promotes the development of Alzheimer pathology. We therefore studied whether longstanding cerebral hypoperfusion is associated with Alzheimer pathology in nondemented humans.METHODS: Cerebral blood flow and amyloid β ((18)F-Flutemetamol) positron emission tomography retention were assessed in eleven patients with unilateral occlusion of
Background: Carbohydrate antigen 125 (CA125) is a mucin produced by serosal cells in response to mechanical and inflammatory stimuli. CA125 has emerged as prognostic biomarker in heart failure (HF) and correlates with markers of fluid overload, echocardiographic parameters and prognosis in HF patients. In patients with acute coronary syndrome (ACS), elevated CA125 is correlated with a higher risk
There is an unmet need to reliably and non-invasively monitor disease progression in preclinical Huntington's disease (HD) models. As a marker of axonal damage, neurofilament light chain (NfL) has been suggested a marker for neurodegeneration. NfL concentrations in blood and CSF were recently shown to have prognostic value for clinical HD progression and brain atrophy. We therefore hypothesized th
Idiopathic pulmonary fibrosis (IPF), an insidious disease with grave prognosis, is characterized by heterogeneous fibrosis with densely fibrotic areas surrounded by nonfibrotic normal-looking tissue, believed to reflect a temporal development. The etiology is incompletely elucidated, but aberrant wound healing is believed to be involved. Embryonic signaling pathways, including Wnt signaling, are r
BACKGROUND: It has been suggested that osteoblasts are involved in the regulation of haematopoietic stem cells. Whether osteocalcin, which is derived from osteoblasts and is metabolically active, influences blood haemoglobin (Hb) levels is not known.OBJECTIVE: To determine whether plasma osteocalcin is a determinant of Hb in elderly men.METHODS: A total of 993 men (mean age 75.3 ± 3.2 years) parti
There is consistent evidence in the literature that an average employee's age is negatively related to firm-level innovativeness. This observation has been explained by older employees working with outdated technological knowledge and being characterized by reduced cognitive flexibility. We argue that firms can mitigate this effect through employee turnover. In particular, turnover of R&D work
In higher plants, genes for subunits of respiratory chain complex I (NADH:ubiquinone oxidoreductase) have so far been identified solely in organellar genomes. At least nine subunits are encoded by the mitochondrial DNA and 11 homologues by the plastid DNA. One of the 'key' components of complex I is the subunit binding the substrate NADH. The corresponding gene for the mitochondrial subunit has no
50 years ago, on June 11, 1963 president John F Kennedy, in live television, gave his commemorated speech to the American people where he declared his demand for civil rights for all Americans. The film Guess who is coming to dinner (Stanley Kramer, 1967) was an attempt to raise this question again by bringing up the topic of interracial marriage. This essay aims at studying how this is done, by s
Objective. Patients with inflammatory bowel disease (IBD) often have low iron stores or anaemia. There is controversy about whether iron should be supplemented orally or intravenously (i.v.). The purpose of this study was to investigate whether treatment with intravenous iron is superior to treatment with oral iron. The primary end-points were response and remaining anaemia at the end of treatment
Single-strand RNA-binding proteins (RBPs) are involved in many aspects of RNA metabolism and in the regulation of gene transcription. The RBP RBM3 was recently suggested to be a proto-oncogene in colorectal cancer; however, such a role has not been corroborated by previous studies in the colon or other tumor types, and the prognostic implications of tumor-specific RBM3 expression remain unclear. M
One of the major roles of seminal plasma is to provide antimicrobial protection for the spermatozoa in the female reproductive tract. We found that the bactericidal activity of seminal plasma was highest after resolution of the seminal clot and that this antibacterial activity subsequently became greatly diminished. The antibacterial activity was derived from peptides generated by fragmentation of
BACKGROUND: Inflammation has been proposed to be important in the pathogenesis of diabetic retinopathy. An early feature of inflammation is the release of cytokines leading to increased expression of endothelial activation markers such as vascular cellular adhesion molecule-1 (VCAM-1). Here we investigated the impact of diabetes and dyslipidemia on VCAM-1 expression in mouse retinal vessels, as we
Variants in the TCF7L2 gene (transcription factor 7-like 2) have shown strong association with type 2 diabetes with two defined risk haplotypes, HapA and HapB(T2D). TCF7L2 may play a role in both glucose homeostasis and adipogenesis. Our aim was to characterize the TCF7L2 mRNA expression and regulation in human adipose tissue. We quantified TCF7L2 mRNA levels in cultured human adipocytes and in bi
Aims/hypothesis: Insufficient insulin release and hyperglucagonaemia are culprits in type 2 diabetes. Cocaine- and amphetamine-regulated transcript (CART, encoded by Cartpt) affects islet hormone secretion and beta cell survival in vitro in rats, and Cart−/− mice have diminished insulin secretion. We aimed to test if CART is differentially regulated in human type 2 diabetic islets and if CART affe
The ECL cells are peptide hormone-producing cells, rich in histamine and chromogranin A (CGA)-derived peptides, that operate under the control of gastrin. Gastrin and the ECL cells form a functional unit, the gastrin-ECL-cell axis. The aims of the present study were to examine (1) if calcitonin (CT), parathyroid hormone (PTH) and vitamin D affect the gastrin-ECL-cell axis (by measuring the activit
Using in vitro and in vivo experimental systems and in situ analysis, we show that growth hormone (GH) is secreted locally by normal human mammary epithelial cells upon progesterone stimulation. GH increases proliferation of a subset of cells that express growth hormone receptor (GHR) and have functional properties of stem and early progenitor cells. In 72% of ductal carcinoma in situ lesions, an
Background and aims: Asthma is one of the most common respiratory diseases in the world. Research has shown that temporal increases in air pollution concentrations can aggravate asthma symptoms. The aim of this study was to assess whether individuals living in areas with higher air pollution concentrations responded differently to short-term temporal exposure to air pollution than those living in
