The frequency and prognostic impact of dic(9;20)(p13.2;q11.2) in childhood B-cell precursor acute lymphoblastic leukemia: results from the NOPHO ALL-2000 trial

The dic(9;20)(p13.2;q11.2) is reported to be present in similar to 2% of childhood B-cell precursor acute lymphoblastic leukemia (BCP ALL). However, it easily escapes detection by G-banding analysis and its true prevalence is hence unknown. We performed interphase fluorescence in situ hybridization analyses-in a three-step manner-using probes for: (i) CDKN2A at 9p21, (ii) 20p and 20q subtelomeres

A short-lived aeolian event during the Early Holocene in southeastern Norway

The Starmoen dune field is part of a larger aeolian system in the Jomna and Glomma river valleys in southeastern Norway. It is believed to have formed just after the last deglaciation in the area, but no absolute ages have been available to support this. Here, we present a set of quartz optically stimulated luminescence (OSL) ages from the aeolian sediments and the underlying glacifluvial deposits

A NEMO potential that includes the dipole-quadrupole and quadrupole-quadrupole polarizability.

To increase the accuracy of molecular force fields a systematical and balanced improvement of the various terms included is needed. In this work, we have followed this strategy to improve the quality of the NEMO potential for the formaldehyde dimer by introducing local quadrupole moments and higher-order polarizabilities. It is found that inclusion of the quadrupole moment significantly improves t

A beta 40 Oligomers Identified as a Potential Biomarker for the Diagnosis of Alzheimer's Disease

Alzheimer's Disease (AD) is the most prevalent form of dementia worldwide, yet the development of therapeutics has been hampered by the absence of suitable biomarkers to diagnose the disease in its early stages prior to the formation of amyloid plaques and the occurrence of irreversible neuronal damage. Since oligomeric A beta species have been implicated in the pathophysiology of AD, we reasoned

Early changes in myocardial repolarization and coronary perfusion after cardiopulmonary bypass surgery for ASD repair in children

Background: In adults, impaired myocardial repolarization and increased risk of arrhythmia are known consequences of open heart surgery. Little is known, however, about post-operative consequences of cardiopulmonary bypass surgery in children. The aim of this study was to assess ventricular repolarization and coronary perfusion after bypass surgery for atrial septal defect (ASD) repair in children

Inter-domain electron transfer in cellobiose dehydrogenase: modulation by pH and divalent cations

The flavocytochrome cellobiose dehydrogenase (CDH) is secreted by wood-decomposing fungi, and is the only known extracellular enzyme with the characteristics of an electron transfer protein. Its proposed function is reduction of lytic polysaccharide mono-oxygenase for subsequent cellulose depolymerization. Electrons are transferred from FADH(2) in the catalytic flavodehydrogenase domain of CDH to

Neuroinflammation in Lyme neuroborreliosis affects amyloid metabolism

Background: The metabolism of amyloid precursor protein (APP) and beta-amyloid (A beta) is widely studied in Alzheimer's disease, where A beta deposition and plaque development are essential components of the pathogenesis. However, the physiological role of amyloid in the adult nervous system remains largely unknown. We have previously found altered cerebral amyloid metabolism in other neuroinflam

Fractionation of wheat and barley straw to access high-molecular-mass hemicelluloses prior to ethanol production.

The cost efficiency of the biorefining process can be improved by extracting high-molecular-mass hemicelluloses from lignocellulosic biomass prior to ethanol production. These hemicelluloses can be used in several high-value-added applications and are likely to be important raw materials in the future. In this study, steam pretreatment in an alkaline environment was used to pretreat the lignocellu

Criteria for medicines management in hospitals

Study objectives: The aim of this study was to develop quality criteria for further development and use in the Medicines Management(MM) process in European hospitals. Methods: Criteria for MM were developed in three steps using a modified two-stage Delphi-technique. In the first step a literature search was performed and 300 topics were listed. These topics were grouped into three dimensions, e

Effects of denosumab on pain and analgesic use in giant cell tumor of bone: Interim results from a phase II study

Background. Giant cell tumor of bone (GCTB) is an aggressive primary osteolytic tumor. GCTB often involves the epiphysis, usually causing substantial pain and functional disability. Denosumab, a fully human monoclonal antibody against receptor activator of nuclear factor. kappa beta ligand (RANKL), is an effective treatment option for patients with advanced GCTB. This analysis of data from an ongo

Bebyggelsestruktur, resande och energi för persontransporter

Det finns en ganska stor samstämmighet bland forskare och också bland många planerare att en rad åtgärder behövs för att transportsystemet skall kunna anpassas till miljömålen. I den här studien har vi undersökt hur olika bebyggelseparametrar påverkar resandet och energianvändningen. Flertalet studier inom området har fokuserat på stora städer. I vår studie har vi analyserat orter i Skåne. Syftet

Regulation of glucagon secretion from pancreatic alpha cells

Glucagon secreted by pancreatic α-cells plays an important role in the regulation of blood glucose. In this thesis, different techniques such as electrophysiology, immunohistochemistry and hormone secretion assay were combined to explore the mechanisms by which glucagon secretion is regulated. Like pancreatic β-cells, which produce insulin, α-cells are electrically excitable and equipped with dif
