Family and School Psychosocial Environment (FSPE): Development of a brief questionnaire measuring perceived psychosocial environments in children/siblings

Persson, B. (2011). Family and School Psychosocial Environment (FSPE): Development of a brief questionnaire measuring perceived psychosocial environments in children/siblings. Scandinavian Journal of Psychology. The aim of the study was to develop a short Swedish standardized, factor analyzed and cross-validated, family and school psychosocial environment questionnaire (FSPE). The study was based

Engineering Cofactor Preference of Ketone Reducing Biocatalysts: A Mutagenesis Study on a γ-Diketone Reductase from the Yeast Saccharomyces cerevisiae Serving as an Example

The synthesis of pharmaceuticals and catalysts more and more relies on enantiopure chiral building blocks. These can be produced in an environmentally benign and efficient way via bioreduction of prochiral ketones catalyzed by dehydrogenases. A productive source of these biocatalysts is the yeast Saccharomyces cerevisiae, whose genome also encodes a reductase catalyzing the sequential reduction of

Prediction of endometrial malignancy in women with postmenopausal bleeding and sonographic endometrial thickness ≥ 4.5 mm.

OBJECTIVE: To build mathematical models to evaluate the individual risk of endometrial malignancy in women with postmenopausal bleeding and sonographic endometrial thickness ≥ 4.5 mm using clinical data, sonographic endometrial thickness and power Doppler ultrasound findings. METHODS: Of 729 consecutive patients with postmenopausal bleeding, 261 with sonographic endometrial thickness ≥ 4.5 mm and

Adaptive impedance matching performance of MIMO terminals with different bandwidth and isolation properties in realistic user scenarios

Using the metric of channel capacity, three dual-antenna multiple-input multiple-output (MIMO) terminals with adaptive impedance matching were evaluated at LTE Band 13 in four different user scenarios using simulation. Each of the three terminals is equipped with a slot-monopole antenna and a planar inverted-F antenna (PIFA). The slot monopole is fixed at one edge of the chassis, whereas the locat

pH-responsive liposome-templated polyelectrolyte nanocapsules

Hollow nanocapsules made of polyelectrolytes, extensively useful for biomedical and biotechnological applications, are produced with a simple Layer-by-Layer approach using liposomes as template. The biocompatible polymers, alginate and chitosan, are alternatively adsorbed onto liposomes allowing the achievement of small size hollow nanocapsules with an average diameter of similar to 280 nm. Hollow

Effects on heart pumping function when using foam and gauze for negative pressure wound therapy of sternotomy wounds

Background: Negative pressure wound therapy (NPWT) has remarkable effects on the healing of poststernotomy mediastinitis. Foam is presently the material of choice for NPWT in this indication. There is now increasing interest in using gauze, as this has proven successful in the treatment of peripheral wounds. It is important to determine the effects of NPWT using gauze on heart pumping function bef

Deteriorated function of cutaneous microcirculation in chronic congestive heart failure

Background Chronic congestive heart failure is a complex condition that leads to dysfunction in the peripheral microcirculation. We have previously shown that vascular reactivity is reduced with increasing age. In this study, we examined a group of very old patients with severe chronic heart failure to test the hypothesis that vascular function is further compromised by a combination of heart fail

Diabetes Mellitus Glucose Prediction by Linear and Bayesian Ensemble Modeling

Diabetes Mellitus is a chronic disease of impaired blood glucose control due to degraded or absent bodily-specific insulin production, or utilization. To the affected, this in many cases implies relying on insulin injections and blood glucose measurements, in order to keep the blood glucose level within acceptable limits. Risks of developing short- and long-term complications, due to both too high

Exposure to Polybrominated Diphenyl Ethers and Male Reproductive Function in Greenland, Poland and Ukraine.

Animal and a few human studies suggest that polybrominated diphenyl ethers (PBDEs) may affect male reproductive function. The aim of the present study was to evaluate if male reproductive function was associated with serum level of PBDEs. We evaluated, in a cross-sectional study, the effects of environmental exposure to BDE-47 and BDE-153 on reproductive hormones and semen quality, including marke

A framework for regularized non-negative matrix factorization, with application to the analysis of gene expression data.

Non-negative matrix factorization (NMF) condenses high-dimensional data into lower-dimensional models subject to the requirement that data can only be added, never subtracted. However, the NMF problem does not have a unique solution, creating a need for additional constraints (regularization constraints) to promote informative solutions. Regularized NMF problems are more complicated than conventio

Association of a hydrophobically modified polyelectrolyte and a block copolymer followed by fluorescence techniques

By using absorption and fluorescence (steady-state and time-resolved) techniques the interaction between a poly(acrylic acid) PAA, randomly grafted with pyrene (Py) units (PAAMePy55) and a triblock copolymer of poly(ethylene oxide) and poly(propylene oxide) (EO20PO68EO20, P123) was investigated. From the fluorescence data it is shown that upon addition of P123 a decrease of the (pyrene-pyrene, Py-

Predicting long-term carbon sequestration in response to CO2 enrichment: How and why do current ecosystem models differ?

Large uncertainty exists in model projections of the land carbon (C) sink response to increasing atmospheric CO2. Free-Air CO2 Enrichment (FACE) experiments lasting a decade or more have investigated ecosystem responses to a step change in atmospheric CO2 concentration. To interpret FACE results in the context of gradual increases in atmospheric CO2 over decades to centuries, we used a suite of se

Dectin-1 and DC-SIGN Polymorphisms Associated with Invasive Pulmonary Aspergillosis Infection

The recognition of pathogen-derived structures by C-type lectins and the chemotactic activity mediated by the CCL2/CCR2 axis are critical steps in determining the host immune response to fungi. The present study was designed to investigate whether the presence of single nucleotide polymorphisms (SNPs) within DC-SIGN, Dectin-1, Dectin-2, CCL2 and CCR2 genes influence the risk of developing Invasive

Causes of premature mortality in Swedish drug abusers: A prospective longitudinal study 1970-2006.

Aims To evaluate premature mortality and causes of death from young adulthood to middle age in a cohort of drug users followed during almost four decades Design Follow-up study of a consecutive cohort of patients with drug abuse/dependence. Methods A cohort of 561 drug abusers, admitted to a detoxification and short-term rehabilitation unit 1970–1978 was followed to December 31st, 2006. Standard

Presynaptic calcium signalling in cerebellar mossy fibres

Whole-cell recordings were obtained from mossy fibre terminals in adult turtles in order to characterize the basic membrane properties. Calcium imaging of presynaptic calcium signals was carried out in order to analyse calcium dynamics and presynaptic GABA B inhibition. A tetrodotoxin (TTX)-sensitive fast Na+ spike faithfully followed repetitive depolarizing pulses with little change in spike dura

Inductive tongue control of powered wheelchairs

Alternative and effective methods for controlling powered wheelchairs are important to individuals with tetraplegia and similar impairments whom are unable to use the standard joystick. This paper describes a system where tongue movements are used to control a powered wheelchair thus providing users, with high level spinal cord injuries, full control of their wheelchair. The system is based on an
