"It's fun, but …" Children with cerebral palsy and their experiences of participation in physical activities.

Abstract Purpose: To explore the experiences of children with cerebral palsy (CP) regarding participation in physical activities, and to describe facilitators and barriers. Methods: Sixteen children with CP 8-11 years old who varied in gross motor, cognitive and communicative function participated in either an individual interview or a focus group. Results: Two categories and 10 sub-categories eme

Bayesian Formulation of Gradient Orientation Matching

Gradient orientations are a common feature used in many computer vision algorithms. It is a good feature when the gradient magnitudes are high, but can be very noisy when the magnitudes are low. This means that some gradient orientations are matched with more confidence than others. By estimating this uncertainty, more weight can be put on the confident matches than those with higher uncertainty.

Perinatal and Family Risk Factors for Hodgkin Lymphoma in Childhood Through Young Adulthood

The incidence of Hodgkin lymphoma has increased among adolescents and young adults in recent decades, but the relevant risk factors in early life are still unknown. A national cohort study was conducted of 3,571,574 individuals born in Sweden in 19732008 and followed up for Hodgkin lymphoma incidence through 2009, to examine perinatal and family risk factors for Hodgkin lymphoma in childhood throu

Anisotropic clay–polystyrene nanocomposites: Synthesis, characterization and mechanical properties

Recent studies on clay–polymer nanocomposites have shown prominent improvements in thermal and mechanical propertieswith the addition of quite small amounts of nanometer sized clay particles. The present work presents characterization of anisotropic clay–polystyrene nanocomposites synthesized via a guided self-assembly technique, employing electric fields to align the clay particles into chain-lik

Matrix Metalloproteinases - keys to healthier blood vessels in diabetes?

In this issue of J Endocrinol, Schuyler et al. show that intimal lesions in atherosclerosis-prone diabetic apoE-/- mice are reduced by insulin treatment. An increase of metalloproteinase-9 expression was observed in untreated diabetic apoE-/- mice; this was absent in insulin-treated mice. The study suggests that hindering of tissue-remodeling metalloproteinases may account for the beneficial effec

A reduced model for the design of glass structures subjected to impact loads

A reduced finite element model for determining the maximum principal stress of a glass pane subjected to dynamic impact load is developed and compared to a full dynamic finite element model. The reduced model is based on the Rayleigh-Ritz method. The Ritz vectors used are determined by simple static load-cases. The model is applicable to centrically and eccentrically applied impact and to glass of

Association between follicle-stimulating hormone receptor polymorphisms and reproductive parameters in young men from the general population.

OBJECTIVE: Follicle-stimulating hormone (FSH) regulates gametogenesis through binding to its receptor (FSHR). In women, the Thr307Ala and Asn680Ser polymorphisms in the FSHR gene affect reproductive function, but it is not clear whether they have any impact on spermatogenesis and have mainly been investigated in infertile men of varying ages. The aim of the present study was therefore to examine

Intravascular ultrasound assessed incomplete stent apposition and stent fracture in stent thrombosis after bare metal versus drug-eluting stent treatment the Nordic Intravascular Ultrasound Study (NIVUS)

Background: This prospective multicenter registry used intravascular ultrasound (IVUS) in patients with definite stent thrombosis (ST) to compare rates of incomplete stent apposition (ISA), stent fracture and stent expansion in patients treated with drug-eluting (DES) versus bare metal (BMS) stents. ST is a rare, but potential life threatening event after coronary stent implantation. The etiology

Plasma lipid fatty acid composition, desaturase activities and insulin sensitivity in Amerindian women

Background and aims: Two Amerindian populations - Shuar women living in the Amazonian rain forest under traditional conditions and urbanized women in a suburb of Lima were studied. The fatty acid composition in plasma lipids and the relationships between fatty acid composition and metabolic variables were studied, as well as in a reference group of Swedish women. Methods and results: Fasting plasm

Characterization of Ambipolar GaSb/InAs Core-Shell Nanowires by Thermovoltage Measurements.

In semiconductor heterostructures with a type II band alignment, such as GaSb-InAs, conduction can be tuned from electron- to hole-dominated using an electrostatic gate. However, traditional conductance measurements give no direct information on the carrier type, and thus limit the ability to distinguish transport effects originating from the two materials. Here, we employ thermovoltage measuremen

Single Step Hybrid Coating Process to Enhance the Electrosteric Stabilization of Inorganic Particles

We report on a single-step coating process and the resulting colloidal stability of silica-coated spindle-type hematite nanoparticles (NPs) decorated with a layer of poly-(acrylic acid) (PAA) polyelectrolyte chains that are partially incorporated into the silica shell. The stability of PAA coated NPs as a function of pH and salt concentration in water was compared to bare hematite particles and si

Genomic selection in relation to bovine milk composition and processability.

Genomic selection is a new technology in which selection decisions are based on direct genomic values (DGVs) or genomic enhanced breeding values (GEBVs). The objective of this study was to evaluate the relations between DGVs and several milk traits important for both the nutritional value and processability of milk. This is a new approach and can be used to increase the knowledge on how genomic se

Bushmeat hunting changes regeneration of African rainforests.

To assess ecological consequences of bushmeat hunting in African lowland rainforests, we compared paired sites, with high and low hunting pressure, in three areas of southeastern Nigeria. In hunted sites, populations of important seed dispersers-both small and large primates (including the Cross River gorilla, Gorilla gorilla diehli)-were drastically reduced. Large rodents were more abundant in hu

Negative pressure wound therapy for post-sternotomy mediastinitis reduces mortality rate and sternal re-infection rate compared to conventional treatment

Objective: Negative pressure wound therapy (NPWT) is a recently introduced treatment modality for post-sternotomy mediastinitis. The aim of this study was to compare the mortality rate, the sternal re-infection rate and the length of hospital stay in patients with post-sternotomy mediastinitis after NPWT and conventional treatment. Methods: We retrospectively analysed 118 patients with post-sterno
