Tyrosine kinase inhibitors improve long-term outcome of allogeneic hematopoietic stem cell transplantation for adult patients with Philadelphia chromosome positive acute lymphoblastic leukemia.

This study aimed to determine the impact of tyrosine-kinase inhibitors given pre- and post-allogeneic stem cell transplantation on long term outcome of patients allografted for Philadelphia chromosome-positive acute lymphoblastic leukemia. This retrospective analysis from the Acute Leukemia Working Party of EBMT included 473 de novo Philadelphia chromosome-positive acute lymphoblastic leukemia pat

Commercial motorcycle drivers' perceptions of risk and road safety in urban Nigeria: an explorative study.

Road traffic injury is a great public health challenge with an emerging trend of increasing rates and high mortality involving commercial motorcycles in Nigeria. A qualitative approach was used with 10 in-depth interviews conducted to explore the risk perceptions of commercial motorcyclists in Ibadan, Nigeria. The data analysis using manifest and latent content analysis resulted in an overarching

Analysis of midwifery students' written reflections to evaluate progression in learning during clinical practice at birthing units.

Written daily reflections during clinical practice on birthing units have been used during several years in midwifery education at Lund University, Sweden. However, the usefulness of these reflections for evaluation of progression in learning and professional development of students has to date not been evaluated. In order to analyse written reflections, two taxonomies developed by Bloom and Pette

Interior aesthetics: an experience-focused approach for the design of brand-specific automotive identity

In this research, two objectives were pursued. Firstly, to develop an experience-focused approach to design, based on a framework for perceptual product experience, and, secondly, to test and verify the proposed methodology through an interior design study of the Hulme.F1 supercar. In the process, experience design criteria were developed, which served creative and evaluative purposes. The final d

The influences of the transfer method and particle surface chemistry on the dispersion of nanoparticles in nanocomposites

The synthesis via in situ polymerization and characterization of nanocomposites (NCs) made from silica (SiO2) nanoparticles in a methyl methacrylate (MMA) monomer matrix is reported. We first investigate the transfer of well-defined spherical silica nanoparticles (NPs) (average radius R = 24.2 +/- 3.2 nm) into the monomer solvent. We study the influence of two transfer methods and different surfac

Perfusion MRI of brain tumours: a comparative study of pseudo-continuous arterial spin labelling and dynamic susceptibility contrast imaging

The purpose of this study was to compare the non-invasive 3D pseudo-continuous arterial spin labelling (PC ASL) technique with the clinically established dynamic susceptibility contrast perfusion magnetic resonance imaging (DSC-MRI) for evaluation of brain tumours. A prospective study of 28 patients with contrast-enhancing brain tumours was performed at 3 T using DSC-MRI and PC ASL with whole-brai

Electrochemical communication between microbial cells and electrodes via osmium redox systems.

Electrochemical communication between micro-organisms and electrodes is the integral and fundamental part of BESs (bioelectrochemical systems). The immobilization of bacterial cells on the electrode and ensuring efficient electron transfer to the electrode via a mediator are decisive features of mediated electrochemical biosensors. Notably, mediator-based systems are essential to extract electrons

Two-center potential correlations and its use to determine effective ion-ion interactions and dielectric permittivities in dipolar solvents

General expressions for two-center electrostatic potential correlations and its use to determine (i) the effective interaction between simple ions in a dipolar solvent and (ii) the dielectric permittivity of the solvent are proposed. Such two-center potential correlations were determined from Monte Carlo simulations of spherically confined dipolar particles embedded in a dielectric medium describe

A new spectrophotometric method for improved indirect measurement of low levels of vitellogenin using malachite green

Vitellogenin (VTG) is a well-known biomarker for endocrine disruption and the measurement of alkali-labile protein bound phosphate (ALP) has been used as an indirect quantification method for VTG in fish, clam and mussel. One limitation of the ALP method has been the insufficient detection limit but with the method presented here this obstacle has been overcome, enabling measurement in fish specie

Dendronised polymer architectures for fuel cell membranes

Multi-step synthetic pathways to low-ion exchange capacity (IEC) polysulfone (PSU) with sulfonic acid functionalized aliphatic dendrons and sulfonated comb-type PSU structures are developed and investigated in a comparative study as non-fluorinated proton exchange membrane (PEM) candidates. In each case the side chains are synthesized and introduced in their sulfonated form onto an azide-functiona

Changing the Mechanical Unfolding Pathway of FnIII(10) by Tuning the Pulling Strength

We investigate the mechanical unfolding of the tenth type III domain from fibronectin (FnIII(10)) both at constant force and at constant pulling velocity, by all-atom Monte Carlo simulations. We observe both apparent two-state unfolding and several unfolding pathways involving one of three major, mutually exclusive intermediate states. All three major intermediates lack two of seven native beta-st

C-erbB2, p27 and G1/S aberrations in human primary breast cancer

Background: C-erbB2 is overexpressed in approximately one-fourth of human breast cancers. In spite of numerous reports suggesting a connection of c-erbB2 overexpression with cell cycle regulation through p27, D cyclins and c-myc. the relationship between c-erbB2 and proliferation through de-regulation of the pRb pathway in primaty breast cancer has not been fully clarified. Materials and Methods:

Long-term treatment and suicidal behavior in severe depression: ECT and antidepressant pharmacotherapy may have different effects on the occurrence and seriousness of suicide attempts.

Our objective in this article is to assess the relation between long-term treatments of depressive episodes and attempted or completed suicide in patients who had had a severe depression at index admission. A blind record evaluation of 96 suicides with a primary severe depression and matched controls has been performed. Out of those, 57 and 33, respectively, bad made suicide attempts. Occurrence o

Joint effects of different human papillomaviruses and Chlamydia trachomatis infections on risk of squamous cell carcinoma of the cervix uteri

This case-control study based in Nordic serum banks evaluated the joint effects of infections with genital human papillomavirus (HPV) types, and Chlamydia trachomatis in the aetiology of cervical squamous cell carcinoma. Through a linkage with the cancer registries, 144 cases were identified and 420 controls matched to them. Exposure to past infections was defined by the presence of specific IgG a

The pattern of variation in leaflet shape and reproductive characters in Lathyrus vernus (L.) Bernh. (Fabaceae)

The pattern of variation in characters closely connected with reproductive fitness and in a presumably weakly selected character, leaflet shape, was studied in the forest-herb Lathyrus vernus. Plants from twenty populations, representing three geographically distinct regions (C. Europe, S. Sweden and C. Sweden), were transplanted to a common garden. Leaflet shape, described using elliptic Fourier

An exact ab initio theory of quantum transport using TDDFT and nonequilibrium Green's functions

We present an exact ab initio theory for describing the motion of interacting electrons through nanoscopic constrictions. Our theory is based on time-dependent density functional theory (TDDFT) and nonequilibrium Green functions. We consider the system electrode-device-electrode initially contacted and in equilibrium, therefore the scheme is thermodynamically consistent. Besides the steady-state r

A concentration polarization model for the ultrafiltration of nonionic surfactants

A theoretical model has been developed that describes ultrafiltration of nonionic surfactants. The model takes into account the fact that surfactants start to aggregate and form micelles at the critical micelle concentration, The model can be used to predict the performance of the membrane if the transport properties inside and at the membrane surface as well as the surfactant association behavior

Damage evolution in elasto-plastic materials - Material response due to different concepts

The purpose of this paper is to show that shortcomings exist in the plasticity induced damage theories. Existing phenomenological thermodynamic approaches used for describing elasto-plasticity coupled with damage are therefore evaluated. Within the concept of effective stress both the postulate of strain equivalence and the postulate of (complementary) energy equivalence, as well as extensions of
