Copoly(arylene ether nitrile) and Copoly(arylene ether sulfone) lonomers with Pendant Sulfobenzoyl Groups for Proton Conducting Fuel Cell Membranes

Three series of fully aromatic ionomers with naphthalene moieties and pendant sulfobenzoyl side chains were prepared via K2CO3 mediated nucleophilic aromatic substitution reactions. The first series consisted of poly(arylene ether)s prepared by polycondensations of 2,6-difluoro-2'-sulfobenzophenone (DFSBP) and 2,6-dihydroxynaphthalene or 2,7-dihydroxynaphthalene (2,7-DHN). In the second series, co

Dissociative double-photoionization of butadiene in the 25-45 eV energy range using 3-D multi-coincidence ion momentum imaging spectrometry

Dissociative double-photoionization of butadiene in the 25-45 eV energy range has been studied with tunable synchrotron radiation using full three-dimensional ion momentum imaging. Using ab initio calculations, the electronic states of the molecular dication below 33 eV are identified. The results of the measurement and calculation show that double ionization from π orbitals selectively triggers t

Image schemas, mimetic schemas, and children’s gestures

Mimetic schemas, unlike the popular cognitive linguistic notion of image schemas, have been characterized in earlier work as explicitly representational, bodily sturctures arising from imitation of culture-specific practical actions (Zlatev 2005, 2007a, 2007b). We performed an analysis of the gestures of three Swedish and three Thai children at the age of 18, 22 and 26 months, in episodes of natur

Smoking at onset of rheumatoid arthritis (RA) and its effect on disease activity and functional status: experiences from BARFOT, a long-term observational study on early RA

Objectives: To assess the effects of smoking on disease outcome in a large cohort of patients with early rheumatoid arthritis (RA). Methods: Between 1996 and 2004, 1787 adult patients (disease duration 5.1, p = 0.005). Significantly fewer current smokers were in remission at 12 months (33%) compared to never smokers (36%) and previous smokers (42%) (p = 0.013). Current smoking at inclusion indepe

Distinct transcriptional control in major immunogenetic subsets of chronic lymphocytic leukemia exhibiting subset-biased global DNA methylation profiles

Chronic lymphocytic leukemia (CLL) can be divided into prognostic subgroups based on the IGHV gene mutational status, and is further characterized by multiple subsets of cases with quasi-identical or stereotyped B cell receptors that also share clinical and biological features. We recently reported differential DNA methylation profiles in IGHV-mutated and IGHV-unmutated CLL subgroups. For the firs

A New Digital Front-End for Flexible Reception in Software Defined Radio

Future mobile terminals are expected to support an ever increasing number of Radio Access Technologies (RAT) concurrently. This imposes a challenge to terminal designers already today. Software Defined Radio (SDR) solutions are a compelling alternative to address this issue in the digital baseband, given its high flexibility and low Non-Recurring Engineering (NRE) cost. However, the challenge stil

Expression of Zinc Finger 23 Gene in Human Hepatocellular Carcinoma

The aim of this study was to investigate the relationship between human zinc finger 23 (ZNF23) expression and clinico-pathological characteristics in patients suffering from hepatocellular carcinoma (HCC), and to investigate ZNF23 expression in relation to cell apoptosis. Patients and Methods: Thirty-seven HCC samples were collected and ZFP23 mRNA levels were determined by real-time reverse transc

A longitudinal study of sick building syndrome among pupils in relation to microbial components in dust in schools in China

There are few longitudinal studies on sick building syndrome (SBS), which include ocular, nasal, throat, and dermal symptoms, headache, and fatigue. We studied the associations between selected microbial components, fungal DNA, furry pet allergens, and incidence and remission of SBS symptoms in schools in Taiyuan, China. The study was based on a two-year prospective analysis in pupils (N = 1143) i

An Aspergillus nidulans GH26 endo-β-mannanase with a novel degradation pattern on highly substituted galactomannans.

The activity and substrate degradation pattern of a novel Aspergillus nidulans GH26 endo-β-mannanase (AnMan26A) was investigated using two galactomannan substrates with varying amounts of galactopyranosyl residues. The AnMan26A was characterized in parallel with the GH26 endomannanase from Podospora anserina (PaMan26A) and three GH5 endomannanases from A. nidulans and Trichoderma reesei (AnMan5A,

Localization of Sunitinib in in vivo Animal and in vitro Experimental Models by MALDI Mass Spectrometry Imaging

The spatial distribution of an anti-cancer drug and its intended target within a tumor plays a major role on determining how effective the drug can be at tackling the tumor. This study provides data regarding the lateral distribution of sunitinib, an oral antiangiogenic receptor tyrosine kinase inhibitor using an in vitro animal model as well as an in vitro experimental model that involved deposit

A prospective cohort study on risk of acute pancreatitis related to serum triglycerides, cholesterol and fasting glucose

Background/objectives: To investigate risk for acute pancreatitis related to moderately elevated triglycerides, cholesterol and fasting glucose. Methods: This was a prospective cohort study in Malmo, Sweden of 33 346 subjects investigated 1974 - 1992 and followed until December 31, 2006. Baseline investigation included a self-administered questionnaire and analysis of serum triglycerides, choleste

Observing as an essential facet of mindfulness: A comparison of FFMQ patterns in meditating and non-meditating individuals.

One of the most comprehensive measures of mindfulness is the Five Facet Mindfulness Questionnaire (FFMQ) with five factors—Observing, Describing, Acting with awareness, Non-judging, and Non-reactivity. Hierarchical confirmatory factor analyses, however, have suggested that only four of the FFMQ factors (i.e. all except Observing) were components of “an overall mindfulness construct”—which is puzzl

The Genetics of Autism Spectrum Disorders and Related Neuropsychiatric Disorders in Childhood.

Objective: Autism spectrum disorders are considered to be among the most heritable mental disorders, a notion based on surprisingly sparse data from small clinical studies. Population-based studies of the heritability of other neuro-psychiatric disorders and comorbidities among them have also been sparse. The authors sought to address both of these issues. Method: Parents of all Swedish 9- and 12-

Hyperbaric oxygen therapy as adjunctive treatment of diabetic foot ulcers.

Hyperbaric oxygen therapy (HBO) is a short-term, high-dose oxygen inhalation and diffusion therapy, delivered systemically through airways and blood under high pressure using hyperbaric chambers. HBO stimulates angiogenesis, reduces edema, augments granulation tissue formation by enhancing fibroblasts, and improves leukocyte function by elevating the partial pressure of oxygen in tissue. The numbe
