Thymidine labelling indices (LI) and the number of clonal chromosome aberrations were assessed in fine‐needle aspirates from enlarged lymph nodes in 22 patients with non‐Hodgkin's lymphoma (NHL). 11 patients had LI > 3.0 (median 8.4) and 11 others had LI < 3.0 (median 1.0). Three categories of chromosome aberration were recorded: normal karyotype, 1–5 aberrations, and ≥ 6 aberrations or multiple c
Floder och åar är viktiga källor för järn och andra näringsämnen till Östersjön. De senaste decennierna har järnkoncentrationen i svenska och finska åar ökat kraftigt, vilket skulle kunna leda till en ökad transport av järn till Östersjön. Vilken effekt detta kan ha för Östersjön beror på vad som händer med järnet när det möter det salta vattnet i Östersjön. Järn transporteras huvudsakligen i formRivers have traditionally not been considered important sources of bioavailable iron (Fe) to the marine waters, since most Fe is lost by salinity-induced aggregation and sedimentation during estuarine mixing. However, recent studies from boreal rivers found a remarkably high Fe stability, probably due to the interaction with organic matter. Recent studies have suggested that Fe speciation is a key
Ectomycorrhizal (ECM) fungi are key players in N cycling in coniferous forests, and forest management such as application of wood ash can affect their functionality. The aim of this study was to determine the effects of wood ash application on ECM fungal mycelial production, capacity to retain N, diversity and community composition. In-growth mesh bags were installed in control and treated plots.
This paper reports findings from a pilot study for the research project SHARP – Shared Reading After Pain Rehabilitation. SHARP explores the feasibility and effect of Shared Reading, a group-based reading intervention, as a way to improve the quality of life for people with chronic non-cancer pain who have undergone a pain rehabilitation programme (5 weeks) at Skåne University Hospital in Sweden.
Some experimental tests were conducted to reveal the enhancement of the ferrofluid heat transfer under a permanent magnetic field. This research aims to investigate the effect of various external magnetic fields on convective heat transfer characteristics of the ferrofluid (magnetic nanofluid). Comparison of theoretical predictions and experimental data were conducted to validate the rationality o
This paper investigates the salience of speech contrasts in noise, in relation to how listening attention affects scalp-recorded cortical responses. The contrasts that were examined with consonant-vowel syllables, were place of articulation, vowel length and voice-onset time (VOT) and our analysis focuses on the correspondence between the effect of attention on the electrophysiology and the decrem
D-programmet pa LTH har en låg andel kvinnliga sökande, samtidigt som intresset för att lära sig programmera bland kvinnor tycks öka. Det finns exempel på att intresset är överväldigande stort när det anordnas programmeringsundervisning som endast är avsedd för kvinnor. Vilka ärintresserade och varför? Kan detta ge oss förslag på vad LTH kan gora för att öka mångfalden på D-programmet? Undersöknin
In this work we discuss a gradient plasticity formulation which relies on the introduction of higher-order gradient contributions as additional arguments of the free energy function. These gradients can be interpreted in terms of the local geometrically necessary dislocation density. This gives rise to physically well-motivated kinematic-type hardening models in contrast to purely phenomenological
The reactions between [VO(acac)2] (acac– = acetylacetonate) and the tripodal amino bisphenols 6,6′-(((2-morpholinoethyl)azanediyl)bis(methylene))bis(2,4-di-tert-butylphenol) (H2L1) and 6,6′-(((thiophen-2-ylmethyl)azanediyl)bis(methylene))bis(2,4-di-tert-butylphenol) (H2L2) as well as the tetradentate amino phenol 2,2′-((3,5-di-tert-butyl-2-hydroxybenzyl)azanediyl)bis(ethan-1-ol) (H3L3) afford the
Combining neo-institutionalism, actor network theory, and Gabriel Tarde's sociology, Czarniawska considers the key driver of organizational change to be imitation but an imitation that rests on translation. Organizations emulate one another by translating fashionable ideas according to their understanding, traditions, needs, and means. As translation in this tradition always entails a transformati
Purpose: To describe a new time-saving threshold visual field–testing strategy—Swedish Interactive Thresholding Algorithm (SITA) Faster, which is intended to replace SITA Fast—and to report on a clinical evaluation of this new strategy. Design: Description and validity analysis for modifications applied to SITA Fast. Methods: Five centers tested 1 eye of each of 126 glaucoma and glaucoma suspect p
In this work, 3-point bending tests and micro-hardness measurements were performed on pure tungsten irradiated with high-energy protons and spallation neutrons in a target of the Swiss Spallation Neutron Source (SINQ). The specimens were irradiated to doses in the range of 1.3–3.5 dpa, with 37–140 appm He, at temperatures between 75 and 110 °C. During 3-point bending tests performed at temperature
In this chapter, we discuss the open challenges in building self-aware computing systems that are still being faced by the research and development community. The challenges can be theoretical, technical, computational, or even sociological. First, we highlight the challenges associated with each of the earlier parts of the book and summarize on respective future research directions. We then offer
Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) has been clinically validated as a target for antimalarial drug discovery, as a triazolopyrimidine class inhibitor (DSM265) is currently undergoing clinical development. Here, we have identified new hydroxyazole scaffold-based PfDHODH inhibitors belonging to two different chemical series. The first series was designed by a scaffold hoppi
Cationic 1,3,5‑triaza‑phosphaadamantane (PTA) quinoline ruthenium(II) and iridium(III) complexes were successfully synthesized and characterized using standard spectroscopic and analytical techniques. The complexes were evaluated for their in vitro antiplasmodial activities against the chloroquine-sensitive (CQS) NF54 and chloroquine-resistant (CQR) K1 strains of the Plasmodium falciparum species
Devices based on molecular motor-driven cytoskeletal filaments, e.g., actin filaments, have been developed both for biosensing and biocomputational applications. Commonly, these devices require nanoscaled tracks for guidance of the actin filaments which has limited the patterning technique to electron beam lithography. Thus, large scale systems become intractable to fabricate at a high throughput
In a population-based group of women, consecutively diagnosed, with premenopausal breast cancer there was a significant correlation between tumour size and plasma prolactin (r=0.30;P<0.004). The concentration of estrogen receptor was negatively correlated to tumour size (r=-0.17;P<0.09). There were no substantial correlations between tumour size and progesterone receptor, plasma progesterone or es
Previous studies on metabolic factors and bladder cancer (BC) risk have shown inconsistent results and have commonly not investigated associations separately by sex, smoking, and tumor invasiveness. Among 811,633 participants in six European cohorts, we investigated sex-specific associations between body mass index (BMI), mid-blood pressure (BP, [systolic + diastolic]/2), plasma glucose, triglycer
