A new expression vector for production of enzymes in the yeast Saccharomyces (lachancea) kluyveri.

We overexpressed and purified enzymes involved in the pyrimidine catabolic pathway in the yeast Saccharomyces (Lachancea) kluyveri. A new vector was therefore designed, providing the first specific expression system in Saccharomyces kluyveri. The URC1 gene was overexpressed and a soluble protein obtained and successfully purified using the C-terminally added His-tag. Our system will be used for fu

Fractures in children with cerebral palsy: a total population study.

AIM: To analyse factors associated with fractures in children with cerebral palsy (CP) in different levels of Gross Motor Function Classification System (GMFCS). METHOD: This was an epidemiological retrospective study of a total population of 536 children (214 females, 322 males) with CP born between 1990 and 2005. CP type was unilateral spastic (n=159), bilateral spastic (n=225), ataxic (n=60), d

The bioeconomy and beyond: Visions and strategies

A bioeconomy can be defined as an economy where the basic building blocks for materials, chemicals and energy are derived from renewable biological resources. Recently, many strategies and visions for the bioeconomy have been produced by industry associations and government agencies. It is apparent from these documents that the actors engaged in the bioeconomy understand the concept in quite diffe

Control and understanding of kink formation in InAs-InP heterostructure nanowires.

Nanowire heterostructures are of special interest for band structure engineering due to an expanded range of defect-free material combinations. However, the higher degree of freedom in nanowire heterostructure growth comes at the expense of challenges related to nanowire-seed particle interactions, such as undesired composition, grading and kink formation. To better understand the mechanisms of ki

Transforming growth factor (TGF)-β levels and unprovoked recurrent venous thromboembolism.

Prediction of recurrence in patients with unprovoked venous thromboembolism (VTE) remains a challenge. Studies of atherosclerosis suggest a protective role of transforming growth factor (TGF)-β. However, the role of TGF-β has not been studied in VTE. The aim of this study was to investigate TGF-β as a predictive marker of recurrent VTE in patients with a first episode of unprovoked VTE. Patients i

Carrier Recombination Dynamics in Sulfur-Doped InP Nanowires.

Measuring lifetime of photogenerated charges in semiconductor nanowires (NW) is important for understanding light-induced processes in these materials and is relevant for their photovoltaic and photodetector applications. In this paper, we investigate the dynamics of photogenerated charge carriers in a series of as-grown InP NW with different levels of sulfur (S) doping. We observe that photolumin

Indicators of soil ecosystem services in conventional and organic arable fields along a gradient of landscape heterogeneity in southern Sweden

Agricultural intensification has been vital for meeting global food demand but has caused environmental degradation. This has disrupted the ability of soil to provide vital ecosystem services. Organic farming is often thought to conserve and utilise soil ecosystem services, and thus be a more sustainable method of food production than conventional farming. However, evidence for this is equivocal,

Do Cyclodextrins Aggregate in Water? Insights from NMR Experiments

One decade ago Bonini et al. [Langmuir 2006, 22, 1478-1484] reported the occurrence of aggregates of beta-cyclodextrin in aqueous Solutions with sizes in the range from 90 nm to a few micrometers. The experimental technique used was cryo-TEM. This work followed a number of previous studies involving other physical parameters, such as viscosities and activity coefficients, the results of which were

The Manager’s Dilemma: A conceptualization of online review manipulation strategies.

Online evaluations are one of the most important innovations in tourism in recent years, often combining a review/rating (business-specific evaluation) and a ranking (inter-business comparison). As online reputation determines economic success, tourism managers may be tempted to manipulate online content. This paper presents the results from a qualitative study involving 20 hotel managers in south

Physical activity and lymphoid neoplasms in the European Prospective Investigation into Cancer and nutrition (EPIC)

Background: Lymphoid neoplasms are a heterogeneous group of cancers that originate in the lymphatic cells of the immune system. Several risk factors have been identified or suggested, but they all account for only a small proportion of the lymphoid neoplasm incidence. It has been hypothesised that regular exercise may modulate the immune system and thereby reduce the risk of developing the disease

MIRD Pamphlet No. 26: Joint EANM/MIRD Guidelines for Quantitative 177Lu SPECT applied for Dosimetry of Radiopharmaceutical Therapy.

Accuracy of absorbed dose calculations in personalized internal radionuclide therapy is directly related to the accuracy of the activity (or activity concentration) estimates obtained at each of the imaging time points. MIRD Pamphlet No. 23 presented a general overview of methods that are required for quantitative SPECT imaging. The present document is next in a series of isotope-specific guidelin

Children's affective experience of every-day travel

This study aims to evaluate if children's affective experience of every-day travel varies depending on travel mode and destination of travel. More specifically, what are children's reported valence (unpleasantness-pleasantness) and activation (deactivation-activation) while travelling to different destinations and does this experience have spill-over effects on how they perceive activities at the

Evaluation of residual stresses in electron-beam welded Zr2.5Nb0.9Hf Zircadyne flange mock-up of a reflector vessel beam tube flange

The dual-phase alloy Zr2.5Nb alloy is an important nuclear material, because of its use in current and possible use in future nuclear reactors. It is, however, well-known that Zr2.5Nb weldments can fail through a time-dependent mechanism called delayed hydride cracking which is typically driven by the presence of tensile residual stresses. With a view to understanding the development of residual s

Skin sensitizers differentially regulate signaling pathways in MUTZ-3 cells in relation to their individual potency.

Due to the recent European legislations posing a ban of animal tests for safety assessment within the cosmetic industry, development of in vitro alternatives for assessment of skin sensitization is highly prioritized. To date, proposed in vitro assays are mainly based on single biomarkers, which so far have not been able to classify and stratify chemicals into subgroups, related to risk or potency
