Study Design. A multicenter, randomized, controlled, cost-effectiveness analysis. Objective. To assess the cost-effectiveness of balloon kyphoplasty (BKP) compared with standard medical treatment (control) in patients with acute/subacute (<3 months) vertebral compression fracture (VCF) due to osteoporosis. Summary of Background Data. Patients with a VCF due to osteoporosis are common and will incr

Indisputably Normalized Cuts is one of the most popular segmentation algorithms in pattern recognition and computer vision. It has been applied to a wide range of segmentation tasks with great success. A number of extensions to this approach have also been proposed, including ones that can deal with multiple classes or that can incorporate a priori information in the form of grouping constraints.

α1-microglobulin (A1M) is a 26 kDa plasma and a tissue protein belonging to the lipocalin family. The reductase and free radical scavenger A1M has been shown to protect cells and extracellular matrix against oxidative and irradiation-induced damage. The reductase activity was previously shown to depend upon an unpaired cysteinyl side-chain, C34, and three lysyl side-chains, K92, 118, and 130, loca

Covalent immobilization of enzymes at electrodes via amide bond formation is usually carried out by a two-step protocol, in which surface carboxylic groups are first activated with the corresponding cross-coupling reagents and then reacted with protein amine groups. Herein, it is shown that a modification of the above protocol, involving the simultaneous incubation of tobacco peroxidase and the py

Ectomycorrhizal fungi play a key role in mobilizing nutrients embedded in recalcitrant organic matter complexes, thereby increasing nutrient accessibility to the host plant. Recent study have shown that during assimilation of nutrients, the ectomycorrhizal fungus Paxillus involutus decomposes organic matter using an oxidative mechanism involving Fenton chemistry (Fe(2+) + H2O2 + H(+) → Fe(3+) + •O

Development of targeted agents for the treatment of diffuse large B-cell lymphoma includes clinical evaluation of enzastaurin, an agent that suppresses signaling through protein kinase C-beta and AKT pathways. To determine whether protein kinase C-beta expression has prognostic significance for diffuse large B-cell lymphoma patients treated with immunochemotherapy, we analyzed the expression of pr

Abstract Background Gender specific outcome for children with anorectal malformations (ARM) is rarely reported although it is important for medical care and in parent counseling. Purpose To assess bowel function according to the Krickenbeck system in relation to ARM-subtype, gender and age. Method All children born with ARM in 1998–2008 and referred to two centers in two different countries wer

Aerosol effects on low-level clouds over the Nordic Countries are investigated by combining in situ ground-based aerosol measurements with remote sensing data of clouds and precipitation. Ten years of number size distribution data from two aerosol measurement stations (Vavihill, Sweden and Hyytiälä, Finland) provide aerosol number concentrations in the atmospheric boundary layer. This is combined

Introduction: Gene amplification of CCND1 is observed in a subgroup of breast cancers with poor prognosis, whereas overexpression of the protein cyclin D-1 has been linked to both worse and better clinical outcome. CCND1 amplification and protein overexpression have also been associated with resistance to treatment with tamoxifen or even to a potentially detrimental effect of tamoxifen. Methods: T

Existing evidence on the effects of manganese and selenium during fetal life on neurodevelopmental disorders is inadequate. This study aims to investigate the hypothesized relationship between fetal exposure to manganese and selenium and attention deficit hyperactivity disorder (ADHD) diagnosis in childhood. Children born between 1978 and 2000 with ADHD (n=166) were identified at the Department of

Aims/hypothesis High plasma copeptin, a marker of vasopressin (VP) secretion, has been shown to be associated with the metabolic syndrome and development of type 2 diabetes in humans. The present study was designed to determine the long-term influence of plasma VP concentration in a rodent model prone to metabolic dysfunction. Methods Obese Zucker rats and their lean counterparts were submitted fo

Methylisothiazolinone (MI) is used as a preservative in occupational and household products, and cosmetics. It is a part of the preparation of methylchloroisothiazolinone (MCI)/MI, which is patch tested in water in the European baseline series. However, this preparation fails to detect a significant percentage of allergic contact reactions to MI.

Young immigrants who suffer from psychosis perceive their illness from the outlook of at least two cultures, which is often a source of confusion and misunderstanding for clients, their families, and clinicians. This article presents a case study with a narrative approach, aiming to illustrate how an occupational therapy intervention can highlight the role of culture and address bicultural identif

Forensic DNA analysis applying PCR enables profiling of minute biological samples. Enhanced analysis conditions can be applied to further push the limit of detection, coming with the risk of visualising artefacts and allele imbalances. We have evaluated the consecutive increase of PCR cycles from 30 to 35 to investigate the limitations of low-template (LT) DNA analysis, applying the short tandem r

Abstract in Romanian ntemeiată la 1348, Universitatea Carolină din Praga se numără printre cele mai vechi instituţii de învăţământ superior din lume. Studiul limbii române beneficiază aici de o bogată tradiţie, acesta fiind introdus la catedra de limbi romanice a Universităţii încă din anul 1882 de către profesorul ceh de filologie Jan Urban Jarník (1848-1923). Este notabil şi faptul că UniversitaFounded in 1348, Charles University in Prague is among the oldest academic institutions in the world. Teaching the Romanian language has a longstanding tradition as well: it was established by the Czech philologist Jan Urban Jarník (1848-1923) within the Romance Department in 1882. Thus Charles University in Prague became the fifth university outside Romania that began teaching Romanian language (

This paper presents an optimization of shell and tube heat exchangers with respect to the total annual costs by a cuckoo search algorithm. The total annual cost is considered as the optimization objective so as to obtain economic heat exchanger structures. The performance of the CSA algorithm is further compared with various algorithm representative of the state of the art in heat exchanger optimi
