The thickness of native oxides on aluminum alloys and single crystals

We present results from measurements of the native oxide film thickness on four different industrial aluminum alloys and three different aluminum single crystals. The thicknesses were determined using X-ray reflectivity, X-ray photoelectron spectroscopy, and electrochemical impedance spectroscopy. In addition, atomic force microscopy was used for micro-structural studies of the oxide surfaces. The

Production of prebiotic xylooligosaccharides from alkaline extracted wheat straw using the K80R-variant of a thermostable alkali-tolerant xylanase

Agricultural by-products are raw materials of importance for increased utilization of renewable biomass. Wheat straw is a raw material of significant production volume and is in this work used for production of xylooligosaccharides (XOS). Extraction of xylan by dilute alkali was followed by hydrolysis using a variant of the alkali-tolerant Bacillus halodurans S7 endoxylanase A mutated at K80R. The

Continuous-wave differential absorption lidar

This work proves the feasibility of a novel concept of differential absorption lidar based on the Scheimpflug principle. The range-resolved atmospheric backscattering signal of a laser beam is retrieved by employing a tilted linear sensor with a Newtonian telescope, satisfying the Scheimpflug condition. Infinite focus depth is achieved despite employing a large optical aperture. The concept is dem

Variability in Neuronal Expression of Dopamine Receptors and Transporters in the Substantia Nigra

Parkinson's disease (PD) patients have increased susceptibility to impulse control disorders. Recent studies have suggested that alterations in dopamine receptors in the midbrain underlie impulsive behaviors and that more impulsive individuals, including patients with PD, exhibit increased occupancy of their midbrain dopamine receptors. The cellular location of dopamine receptor subtypes and trans

Effects of mating system on adaptive potential for leaf morphology in Crepis tectorum (Asteraceae).

Background and Aims A shift from outcrossing to selfing is thought to reduce the long-term survival of populations by decreasing the genetic variation necessary for adaptation to novel ecological conditions. However, theory also predicts an increase in adaptive potential as more of the existing variation becomes expressed as homozygous genotypes. So far, relatively few studies have examined how a

How do nurses in palliative care perceive the concept of self-image?

Nursing research indicates that serious illness and impending death influence the individual's self-image. Few studies define what self-image means. Thus it seems to be urgent to explore how nurses in palliative care perceive the concept of self-image, to get a deeper insight into the concept's applicability in palliative care.

The ideology of neuroscience and intellectual disability: reconstituting the 'disordered' brain

During the last two or three decades, neuroscience has changed how we understand brain functioning. This shift, which is re-conceptualizing the relationship between the materiality of the brain and consciousness, is bound to have implications for intellectual disability, which is commonly seen as a condition of the brain. At present, examinations of intellectual disability that deploy techniques a

Auditory event-related potentials are related to cognition at preschool age after preterm birth

Background:Auditory event-related potentials (AERP) are neurophysiological correlates of sound perception and cognitive processes. Our aim was to study in very preterm born children at preschool age if AERP correlate with cognitive outcome.Methods:Seventy children (mean ± SD gestational age 27.4 ± 1.9 wk, birth weight 996 ± 288 g) were investigated at age 4.3-5.3 y with psychological testing (WPPS

High levels of cystatin C predict the metabolic syndrome: the prospective Malmö Diet and Cancer Study.

OBJECTIVE: Cystatin C is a novel marker of cardiovascular disease (CVD), however the underlying mechanisms remain unclear. Here, we prospectively investigated whether plasma levels of cystatin C predict new-onset metabolic syndrome (MetS) as well as long-term progression and incidence of the different components of the MetS. METHODS: Cystatin C was measured in 1502 individuals included in the Malm

Evidence for altered inflammatory and repair responses in symptomatic carotid plaques from elderly patients.

Most acute cardiovascular events are caused by rupture of an atherosclerotic plaque. The incidence of cardiovascular events increases with age and inflammation is generally considered to be the main cause of increased plaque vulnerability. However, the relationship between age and plaque inflammation has not yet been fully clarified. The aim of our study was to determine if age-dependent plaque vu

Surveillance vs. adjuvant therapy of clinical stage I testicular tumors - a review and the SWENOTECA experience

Although clinical stage I (CS I) testicular cancer is highly curable, the optimal management is controversial. The aims of the Swedish and Norwegian Testicular Cancer Group (SWENOTECA) studies for CS I non-seminoma (NS) and seminoma (S) have been to reduce treatment intensity while maintaining high survival rates, reduce the number of patients needing salvage treatment and implement patient autono

Soil resistivity monitoring of an irrigation experiment

Resistivity measurements were used for tracing water transport during a three-year irrigation study. Three different rates of landfill leachate irrigation and one control treatment were applied to two cultivars of short-rotation willow coppice. Groundwater level measurements and water sampling were carried out in pipes installed in the centre of each plot. Resistivity was measured with permanently

Role of WT1-ZNF224 interaction in the expression of apoptosis-regulating genes

The transcription factor Wilms tumor gene 1, WT1, is implicated both in normal developmental processes and in the generation of a variety of solid tumors and hematological malignancies. Physical interactions of other cellular proteins with WT1 are known to modulate its function. We previously identified the Krppel-like zinc-finger protein, ZNF224, as a novel human WT1-associating protein that enha

Joint scientific statement of the European Association for the Study of Obesity and the European Society of Hypertension: obesity and early vascular ageing.

Current cardiovascular risk scores do not include obesity or fat distribution as independent factors, and may underestimate risk in obese individuals. Assessment of early vascular ageing (EVA) biomarkers including arterial stiffness, central blood pressure, carotid intima-media thickness and flow-mediated vasodilation may help to refine risk assessment in obese individuals in whom traditional card

Long-Term Outcome of Mustard/Senning Correction for Transposition of the Great Arteries (TGA) in Sweden and Denmark.

-The atrial switch operation Mustard- or Senning operation for transposition of the great arteries (TGA) was introduced in the late 1950s and was the preferred surgery for TGA until the early 1990s. The Mustard- and Senning operation involves extensive surgery in the atria and leaves the right ventricle as the systemic ventricle. The Mustard and Senning cohort is now well into adulthood and we beg

Subcutaneous continuous infusion of apomorphine has been shown to effectively reduce off-time and dyskinesias in Parkinson's disease (PD). In this multicentre observational cohort study we investigated motor effectivity, tolerability and patient satisfaction with subcutaneous apomorphine infusion therapy over a follow-up period of 2 years. 62 PD patients were included (34 women, 28 men; median age
