Few differences in cytokines between patients newly diagnosed with type 1 diabetes and their healthy siblings

The cause of the worldwide increase in type 1 diabetes (T1D) is largely unknown. T cells are thought to play a role in disease progression. In contemporary research over the last decade, age- and gender-specific serum levels as well as changes of Th1 and Th2-related cytokines are not well described. From a population-based register of children diagnosed from 1997 to 2005 this study explores eight

Relationship between apoptotic markers in semen from fertile men and demographic, hormonal and seminal characteristics

Apoptosis in the testis has two putative roles during normal spermatogenesis; limitation of the germ cell population to numbers that can be supported by the Sertoli cells, and, possibly, selective depletion of meiotic and postmeiotic abnormal germ cells. We investigated the demographic and biological correlates of the pro-apoptotic marker Fas and the anti-apoptotic marker Bcl-xL in sperm cells of

Productivity and patient satisfaction in primary care-Conflicting or compatible goals?

Following recent reforms in Swedish primary care, providers are accountable to both citizens and county councils, in their role as payers. Productivity and quality measurement is fundamental for ensuring health care providers accountability to payers and that resources are spent as intended. The purpose was to study productivity and patient satisfaction in Swedish primary care. One measure of prod

Efficient and Effective Learning for Safety from Incidents

Learning from incidents is important for improving safety. Many companies spend a great deal of time and money on such learning procedures. The objectives of this paper are to present some early results from a project aimed at revealing weaknesses in the procedures for learning from incidents and to discuss improvements in these procedures, especially in chemical process industries. The empirical

Synthesis, nanostructures and properties of sulfonated poly(phenylene oxide) bearing polyfluorostyrene side chains as proton conducting membranes

Graft copolymers with ionic backbones and hydrophobic fluorinated side chains have been prepared by using lithiated poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) as a macroinitiator for anionic polymerization of 4-fluorostyrene. After grafting of the poly(4-fluorostyrene) (PFS) side chains, the PPO backbone was selectively sulfonated using trimethylsilylchlorosulfonate under mild and controlled con

Oral poly(ADP-ribose) polymerase inhibitor olaparib in patients with BRCA1 or BRCA2 mutations and advanced breast cancer: a proof-of-concept trial

Background Olaparib, a novel, orally active poly(ADP-ribose) polymerase (PARP) inhibitor, induced synthetic lethality in BRCA-deficient cells. A maximum tolerated dose and initial signal of efficacy in BRCA-deficient ovarian cancers have been reported. We therefore assessed the efficacy, safety, and tolerability of olaparib alone in women with BRCA1 or BRCA2 mutations and advanced breast cancer. M

Phase-behavior of alkyl ketene dimmer (AKD) in supercritical carbon dioxide. The implications of using different solubility measurement methods

In this work, three different methods were used to determine the phase behavior of alkyl ketene dimer (AKD) in supercritical carbon dioxide (SC-CO2). Rough values for the total solubility of AKD in SC-CO2 were obtained. The solubility ranges from 1 to 14 mg AKD/g CO2 at temperatures from 40 to 80 degrees C and pressures from 10 to 30 MPa. A significant increase in solubility was observed in the re

Alpha-Synuclein Repeat Variants and Survival in Parkinson's Disease

Objectives: To determine whether alpha-synuclein dinucleotide repeat (REP1) genotypes are associated with survival in Parkinson's disease (PD). Methods: Investigators from the Genetic Epidemiology of Parkinson's Disease Consortium provided REP1 genotypes and baseline and follow-up clinical data for cases. The primary outcome was time to death. Cox proportional hazards regression models were used t

Minimization of economical losses due to utility disturbances in the process industry

A process industrial site may consist of several production areas, some producing intermediate products for further refinement in other areas, and some producing end products. The areas may share the same utilities, such as steam and cooling water, which means that the areas could be connected both by the flow of products through the site and by the use of the same utilities. Management of utility

Genetic vasopressin 1b receptor variance in overweight and diabetes mellitus.

Recently, imbalance in the vasopressin (AVP) system, measured as elevated levels of copeptin (the c-terminal part of the AVP pro-hormone) in plasma, was linked to development of abdominal obesity and diabetes mellitus (DM). Here, we aim to investigate if genetic variation of the human AVP receptor 1b gene (AVPR1B) is associated with measures of obesity and DM.

Agricultural growth and institutions: Sweden 1700-1860

The dating and explanation of the agricultural revolution in Europe remains an elusive research task. When and why did a low-productive pre-industrial agricultural sector turn into a fast-growing, more productive one? Unique data from Sweden, consisting of more than 80,000 observations of farm production output for the period 1700–1860, is used to calculate and explain decisive changes in pre-indu

On the Dynamics of Semimartingales with Two Reflecting Barriers

We consider a semimartingale X which is reflected at an upper barrier T and a lower barrier S, where S and T are also semimartingales such that T is bounded away from S. First, we present an explicit construction of the reflected process. Then we derive a relationship in terms of stochastic integrals linking the reflected process and the local times at the respective bathers to X, S, and T. This r

Impact of human population density on fire frequency at the global scale

Human impact on wildfires, a major earth system component, remains poorly understood. While local studies have found more fires close to settlements and roads, assimilated charcoal records and analyses of regional fire patterns from remote-sensing observations point to a decline in fire frequency with increasing human population. Here, we present a global analysis using three multi-year satellite-

Comparison of health care experience and access between young and older adults in 11 high-income countries

Purpose Young adults (18–24 years) frequently report poorer health care access and experience than older adults. We aimed to investigate how differences between young and older adults vary across 11 high-income countries. Methods A total of 20,045 participants from 11 high-income countries (i.e., Australia, Canada, France, Germany, the Netherlands, New Zealand, Norway, Sweden, Switzerland, United

Corticobasal and ataxia syndromes widen the spectrum of C9ORF72 hexanucleotide expansion disease

Recently, a hexanucleotide (GGGGCC) repeat expansion in the first intron of C9ORF72 was reported as the cause of chromosome 9p21-linked frontotemporal dementia-amyotrophic lateral sclerosis (FTD-ALS). We here report the prevalence of the expansion in a hospital-based cohort and associated clinical features indicating a wider clinical spectrum of C9ORF72 disease than previously described. We studie
