Activating mutations of codon 816 of the Kit gene have been implicated in malignant cell growth of acute myeloid leukemia (AML), systemic mastocytosis and germ cell tumors. Substitution of aspartic acid with valine (D816V) renders the receptor independent of ligand for activation and signaling. Wild-type c-Kit is a tyrosine kinase receptor that requires its ligand, stem cell factor (SCF), for acti

Background: Total plasma homocysteine (tHcy) concentration is elevated in patients with psychogeriatric disease. There are many different determinants of plasma tHcy concentration, including the presence of vascular disease. Method: We investigated plasma tHcy levels in several different subgroups of vascular disease and also the relation between plasma tHcy and renal function in patients with psy

AIM: The aim of this paper was to define the incidence of disease progression of the contralateral internal carotid artery (CICA) in patients undergoing carotid endarterectomy (CEA) and to identify factors influencing disease progression. METHODS: Patients from our primary catchment area that had undergone CEA between 2002 and 2005 were included. The study cohort was divided in four groups based

A few patients have been shown to develop severe abdominal pain and gastrointestinal dysmotility during treatment with gonadotropin‑releasing hormone (GnRH) analogs. A rat model of enteric neuropathy has been developed by administration of the GnRH analog buserelin to rats. Loss of enteric neurons and ganglioneuritis throughout the gastrointestinal tract has been described, without other histopath

Mesh networking is currently gaining much attention, within both academia and industry. Mesh networking allows cheap and fast deployment of wireless services. It is regarded as a very promising solution for urban deployment scenarios as well as for temporary emergency response situations. Another related promising field is that of ad hoc wireless networking, which consists of mobile nodes that dyn

Background. To characterize participant reasons for withdrawing from a diabetes focused longitudinal clinical observational trial (TEDDY) during the first three study years. Methods. 8677 children were recruited into the TEDDY study. At participant withdrawal staff recorded any reason parents provided for withdrawal. Reasons were categorized into (1) family characteristics and (2) protocol reasons

Weight loss improves insulin sensitivity and glucose tolerance in obese subjects with impaired glucose tolerance (IGT), but the long term dynamic effects on blood metabolites other than glucose during an oral glucose tolerance test (OGTT), are largely unknown. Here, we studied changes in OGTT-elicited metabolite patterns in obese subjects during a diet-induced weight loss study.

Children, in contrast to adults, show an excellent clinical recovery after a peripheral nerve injury, which may be explained by better peripheral nerve regeneration and a superior plasticity in the young brain. Our aim was to study the long-term electrophysiological outcome after nerve repair in children and young adults and to compare it with the clinical outcome. Forty-four patients, injured at

Abstract OBJECTIVE: To evaluate the association between radiographic hip osteoarthritis (OA) and future total hip replacement (THR) due to OA or hip fracture. METHODS: We studied a cohort of individuals who had colon radiography from 1980-1997. Minimal joint space (MJS) was measured and each hip was graded for radiographic OA according to the Kellgren/Lawrence scale. Subjects were followed until t

Are the semantic categories of very closely related languages the same? We present a new methodology for addressing this question. Speakers of English, German, Dutch and Swedish described a set of video clips depicting cutting and breaking events. The verbs elicited were then subjected to cluster analysis, which groups scenes together based on similarity (determined by shared verbs). Using this te

Radiotherapy to the head and neck region leads to severe side effects in the oral cavity but knowledge about severity and onset is scarce among oncology nurses in a radiotherapy department. The aim was to test the Oral Assessment Guide for reliability and validity for patients receiving radiotherapy to the head and neck region. A prospective design with repeated assessments was selected. Thirty-si

Density-dependent reproduction is commonly explained by either the habitat heterogeneity (HHH) or individual adjustment (IAH) hypothesis. Under the HHH, high quality territories are assumed to be occupied first. At higher density, occupation of low-quality territories increases due to lower availability of high-quality territories, which reduces mean reproductive success. Alternatively, the IAH as

Purpose. To investigate the clinical and electrophysiologic effect of a single intravitreal injection of bevacizumab for neovascular glaucoma (NVG) after ischemic central retinal vein occlusion (iCRVO). Methods. Nineteen eyes from 19 patients with NVG secondary to iCRVO were randomly allocated to either an intravitreal bevacizumab injection and panretinal photocoagulation (PRP) (10 eyes) or PRP al

Summary Background: Serum has the ability to neutralize the procoagulant properties of anionic liposomes, with transfer of phospholipids (PLs) to both high-density lipoprotein (HDL) and low-density lipoprotein (LDL) particles. Phospholipid transfer protein (PLTP) mediates transfer of PLs between HDL and other lipoproteins and conversion of HDL into larger and smaller particles. Objectives: To exam

Moraxella catarrhalis is an emerging human respiratory pathogen in patients with chronic obstructive pulmonary disease (COPD) and in children with acute otitis media. The specific secretion machinery known as outer membrane vesicles (OMVs) is a mechanism by which Gram-negative pathogens interact with host cells during infection. We identified 57 proteins in M. catarrhalis OMVs using a proteomics a

OBJECTIVE: Left heart failure (LHF) is a common and frequently overlooked condition owing to insufficient diagnostic methods. This can potentially delay onset of treatment. Our clinical experience with ventilation/perfusion single photon emission computed tomography (V/P SPECT) indicates that perfusion shows an antigravitational distribution pattern in LHF. The aim of the study was to test the hyp

Thymic stromal lymphopoietin (TSLP) is an interleukin-7-like cytokine expressed by epithelial cells and reported to be involved in allergic diseases and atopic eczema. The presence of several predicted α-helical regions in TSPL, a structure characterizing many classical antimicrobial peptides (AMPs), prompted us to investigate whether TSLP exerts antimicrobial activities. Recombinant human TSLP ex

Procedures for the initial management of children newly diagnosed with diabetes vary greatly worldwide and the evidence available is insufficient for conclusively determining the best process regarding hospital-based or home-based care. The aim of the study was to compare two different regimens for children with newly diagnosed type 1 diabetes; hospital-based care and hospital-based home care (HBH
