Screening for gene copy-number alterations (CNAs) has improved by applying genome-wide microarrays, where SNP arrays also allow analysis of loss of heterozygozity (LOH). We here analyzed 10 chronic lymphocytic leukemia (CLL) samples using four different high-resolution platforms: BAC arrays (32K), oligonucleotide arrays (185K, Agilent), and two SNP arrays (250K, Affymetrix and 317K, Illumina). Cro

Objective: To design an economic model describing the costs and outcomes for patients treated with tumour necrosis factor alpha ( TNF alpha) inhibitors for rheumatoid arthritis ( RA) in current clinical practice in Sweden, to be used as a tool to estimate cost- effectiveness of the next generation of treatments. Methods: The model was constructed as a discrete event simulation ( DES) model analyse

Following the heavy-ion fusion-evaporation reaction S-32+Mg-24 at 95 MeV beam energy the lifetimes of analogue states in the T-z=+/-1/2 A=51 mirror nuclei Fe-51 and Mn-51 have been measured using the Cologne plunger device coupled to the GASP gamma-ray spectrometer. The deduced B(E2;27/2(-)-->23/2(-)) values afford a unique opportunity to probe isoscalar and isovector polarization charges and to d

In order to obtain a better understanding of the role of conformational disorder in the photophysics of conjugated polymers the ultrafast transient absorption anisotropy of partially deconjugated MEH-PPV has been measured. These data have been compared to the corresponding kinetics of Monte Carlo–simulated polymer chains, and estimates of the energy hopping time and energy migration distances for

he conservation process involves recognizing and listing rare and decreasing species, recording their distribution, biology and specific threats, proposing conservation programmes, and executing these programmes. There are large gaps in our knowledge about bryophytes which must be filled before their conservation can be selective. These include taxonomy, bryogeography, habitat demands, natural dy

This report describes the ascertainment of Parkinson disease (PD) in all individuals aged 50 years or older (49,814 individuals) from the Swedish Twin Registry. In phase one of the study, all twins were screened for PD using telephone interviews, with a response rate of 72.7%. In phase two, twins with suspected PD were re-contacted to exclude anyone from follow-up who reported parkinsonian symptom

The cooling rates of C-60(-) have been measured in an electrostatic storage ring between several hundred mu s and several tens of ms with one-photon laser excitation. The absolute energy scale is established by the photon energy, and the cooling time interval is derived from the nonexponential decay of the ensemble of hot molecules. The energy decreases due to the combined action of depletion and

Dilute solutions of -lactoglobulin (-Lg) A, B, and C were heated at temperatures between about 40 and 94 C for 10 min, cooled, and analyzed using Trp fluorescence and extrinsic fluorescence spectra of the probe 1,8-anilinonaphthalene sulfonate (ANS). Thiol availabilities using 5,5'-dithiobis(2-nitrobenzoic acid) (DTNB) were determined using a separate set of samples. The normalized ANS fluorescenc

Economic evaluation in health care is still an evolving discipline. One of the current controversies in cost-effectiveness analysis regards the inclusion or exclusion of future non-medical costs (i.e. consumption net of production) due to increased survival. This paper examines the implications of a symmetry rule stating that there should be consistency between costs included in the numerator and

The Wnt-5a gene encodes a secreted protein that controls several normal processes during embryogenesis and development of adult tissues by as yet unknown mechanisms. Endogenous expression of Wnt-5a mRNA is known to occur in both mouse and human mammary cell lines. To investigate the biological role of Wnt-5a in the human mammary epithelial cell line HB2, we used an antisense approach to repress en

The present study tested, and found support for, the hypotheses that crime victims with acute post-traumatic stress disorder have: (1) a general memory impairment for faces; and (ii) a memory bias for faces that they perceive as hostile, even when these faces are not arranged to show any hostile face expressions. It is suggested that crime victims with acute post-traumatic stress disorder perform

The free energy of interaction between two nanometric clay platelets immersed in an electrolyte solution has been calculated using Monte Carlo simulations as well as direct integration of the configurational integral. Each platelet has been modeled as a collection of charged spheres carrying a unit charge-the face of a platelet contains negative charges, and the edge, positive charges. The calcula

The objective of the study was to investigate whether spontaneous and iatrogenic preterm births are associated with different paediatric outcomes. A nationwide population-based study comprising 1 010 487 singletons used data from 1991 to 2001 from the Swedish Medical Birth Register and the Swedish Hospital Discharge Register. Intrauterine fetal deaths, unknown type of delivery onset and congenital

There is an increasing interest in how oxidative stress can cause cells to go into apoptosis in both normal ageing and in neurodegenerative disorders. Previous research has implicated insulin-like growth factor-1 (IGF-1) as being involved in the pathogenesis in Alzheimer's disease (AD) by protecting the neurons through reducing neuronal susceptibility to oxidative stress. IGF-1 receptor (IGF-1R) p

Transverse single-spin asymmetries to probe the transverse-spin structure of the proton have been measured for neutral pions and nonidentified charged hadrons from polarized proton-proton collisions at midrapidity and root s = 200 GeV. The data cover a transverse momentum (pT) range 1.0-5.0 GeV/c for neutral pions and 0.5-5.0 GeV/c for charged hadrons, at a Feynman-x value of approximately zero. T

Microchip immobilized enzyme reactors (mu IMERs) with immobilized endoglucanases were applied for the hydrolysis of methyl cellulose (MC). MCs of various molecular weights were hydrolyzed using two mu IMERs containing immobilized celloendoglucanase Cel 5A from Bacillus agaradhaerens (BaCel 5A) connected in series. Hydrolysis by the mu IMER could be confirmed from the average molar masses and molar

In order to understand the state of test process practices in the software industry, we have conducted a qualitative survey, covering software development departments at 11 companies in Sweden of different sizes and application domains. The companies develop products in an evolutionary manner, which means either new versions are released regularly, or new product variants under new names are relea
