Microdeletions are a general feature of adult and adolescent acute lymphoblastic leukemia: Unexpected similarities with pediatric disease

We present here a genome-wide map of abnormalities found in diagnostic samples from 45 adults and adolescents with acute lymphoblastic leukemia (ALL). A 500K SNP array analysis uncovered frequent genetic abnormalities, with cryptic deletions constituting half of the detected changes, implying that microdeletions are a characteristic feature of this malignancy. Importantly, the pattern of deletions

Simulating worst case scenarios and analyzing their combined effect in operational release planning

Operational release planning (ORP) is concerned with assigning human resources to development tasks in software projects such that a defined set of product features can be completed under given constraints. In this paper, we present a simulation-based approach to study the impact of uncertainty. Uncertainty parameters considered in this paper are related to the features themselves (functionality,

Negative UV–NIL (NUV–NIL) – A mix-and-match NIL and UV strategy for realisation of nano- and micrometre structures

This paper presents a novel strategy for aligning patterns created with nano-imprint lithography (NIL) and UV lithography, similar to a mix-and-match process, which allows for the fabrication of large and small features in a single layer of resist. The resin used to demonstrate this new imprinting scheme is SU-8, a very widely used negative photoresist. Rapid stamp manufacturing using ma-N 2405 ph

Computational predictions of binding affinities to dihydrofolate reductase: synthesis and biological evaluation of methotrexate analogues

The relative binding affinities to human dihydrofolate reductase of four new potential antifolates, containing ester linkages between the two aromatic systems, were estimated by free energy perturbation simulations. The ester analogue, predicted to exhibit the highest binding affinity to human dihydrofolate reductase, and a reference ester (more structurally related to methotrexate) were synthesiz

Bucket hashing with a small key size'

In this paper we consider very fast evaluation of strongly universal hash functions, or equivalently, authentication codes. We show how it is possible to modify some known families of hash functions into a form such that the evaluation is similar to “bucket hashing”, a technique for very fast hashing introduced by Rogaway. Rogaway’s bucket hash family has a huge key size, which for common paramete

Resilience of a zooplankton community subjected to marine intrusion in a tropical coastal lagoon

One of the main disturbances on Imboassica Lagoon is the occasional artificial opening of its sand bar. Following two such events, two environmental gradients were observed. One was directly related to entry of marine water ( salinity gradient); and the other to a decrease in dilution of the nutrient load, because of water level reduction ( trophic status gradient). Two stations were sampled. At S

Biometrics and sub-specific identification of white-spotted Bluethroats (Luscinia svecica cyanecula and L. s. namnetum) during autumn and winter.

Detailed analyses of the biometrics of white-spotted bluethroats captured in the Iberian Peninsula and sub-Saharan Africa show that previous criteria for diagnosing subspecies are inadequate. This deficiency seems to result from feather wear during the breeding period and so new criteria are proposed for the migratory and wintering periods. Foreign recoveries in Portugal indicate that the new crit

Effect of the quinoline-3-carboxamide ABR-215757 during inflammation

ABR-215757 (5757) is a quinoline-3-carboxamide (Q-compound) currently in clinical development for systemic sclerosis. Q-compounds have shown efficacy in several different models of autoimmune diseases such as experimental autoimmune encephalomyelitis (EAE) and collagen induced arthritis. However, the mechanism of action is still poorly understood. In this thesis we have tried to find the mechanism

The global distribution and evolution of deoxyribonucleoside kinases in bacteria

Deoxyribonucleoside kinases (dNKs) are important to DNA metabolism, especially in environments where nucleosides are freely available to be absorbed and used for the salvage pathway. Little has previously been known about the complement of dNKs in different bacterial genomes. However, it was believed that Gram-negative bacteria had a single dNK, while Gram-positive bacteria possessed several. An a

A Measure of Septum Shape Using Shortest Path Segmentation in Echocardiographic Images of LVAD Patients

Patients waiting for heart transplantation due to a failing heart can get a left ventricular assist device (LVAD) implanted through open chest surgery. The device consists of a pump that pumps blood from the left ventricle into the aorta. To get the correct rotation speed of the pump, the physicians consider a number of measurements as well as a sequence of echocardiographic images. The important

Screening Detected Celiac Disease in Children

Popular Abstract in Swedish Bakgrund och syfte med avhandlingen Glutenintolerans, celiaki är en av de vanligaste kroniska sjukdomarna bland barn och innebär att man inte tåler gluten, som är ett protein och finns i vete, råg och korn. Tunntarmen har en veckad slemhinna med fingerlika utskott , tarmludd och hela tarmen har en yta på 250 kvadratmeter, vilket är lika stort som en tennisplan. Den stBackground: The prevalence of celiac disease (CD) is estimated to be around 1%, but most CD cases are undiagnosed. Sweden experienced an epidemic of clinically detected celiac disease in children younger than 2 years of age, partly due to changes in infant feeding practices, were the amount of gluten and age at introduction was changed. However, it was not clear if the increase in clinically detec

Dendronized Polymers: Molecular Objects between Conventional Linear Polymers and Colloidal Particles

The term molecular object (MO) is introduced to describe single, shape persistent macromolecules that retain their form and mesoscopic dimensions irrespective of solvent quality and adsorption onto a surface. The concept is illustrated with results concerning homologous series of dendronized polymers (DP). In particular, we discuss imaging experiments quantifying deformation upon adsorption, defec

Multireference Ab Initio Calculations of g tensors for Trinuclear Copper Clusters in Multicopper Oxidases.

EPR spectroscopy has proven to be an indispensable tool in elucidating the structure of metal sites in proteins. In recent years, experimental EPR data have been complemented by theoretical calculations, which have become a standard tool of many quantum chemical packages. However, there have only been a few attempts to calculate EPR g tensors for exchange-coupled systems with more than two spins.

Incidence and survival in non-hereditary amyloidosis in Sweden

Background: Amyloidosis is a heterogeneous disease caused by deposition of amyloid fibrils in organs and thereby interfering with physiological functions. Hardly any incidence data are available and most survival data are limited to specialist clinics. Methods: Amyloidosis patients were identified from the Swedish Hospital Discharge and Outpatients Registers from years 2001 through 2008. Results:

Risk factors for Clostridium difficile toxin-positive diarrhea: a population-based prospective case-control study

Increased incidence and severity of Clostridium difficile infections (CDIs) is of major concern. However, by minimizing known risk factors, the incidence can be decreased. The aim of this investigation was to calculate the incidence and assess risk factors for CDI in our population. A 1-year prospective population-based nationwide study in Iceland of CDIs was carried out. For risk factor evaluatio

Using tonal cues to predict inflections

The present article discusses the Central Swedish word accents – Accent 1 and Accent 2 – and their productive association to suffixes from the point of view of prediction theories of speech processing. Based on recent neurophysiological findings, we propose that both word accents are used predictively, but that Accent 1 is more ‘predictively useful’ than Accent 2, due to the fact that Accent 1 ste

Multiconfigurational quantum chemical methods for molecular systems containing actinides

Recent advances in computational actinide chemistry are reported in this tutorial review. Muticonfigurational quantum chemical methods have been employed to study the gas phase spectroscopy of small actinide molecules. Examples of actinide compounds studied in solution are also presented. Finally the multiple bond in the diuranium molecule and other diactinide compounds is described.
