Fixed drug eruption induced by indapamide. Cross-reactivity with sulfonamides

Indapamide is a nontiazidic sulfonamide diuretic which has not been previously reported as a cause of fixed drug eruption. We describe a patient who experienced several episodes of fixed drug eruption during treatment with indapamide. The diagnosis was confirmed by positive controlled oral challenge test. The possible existence of cross-reactivity with other sulfonamide derivatives was investigate

Conditions and costs for renewables electricity grid connection: Examples in Europe

This paper compares conditions and costs for RES-E grid connection in selected European countries. These are Germany, the Netherlands, the United Kingdom, Sweden, Austria, Lithuania and Slovenia. Country specific case studies are presented for wind onshore and offshore, biomass and photovoltaic power systems, as based on literature reviews and stakeholder interviews. It is shown that, especially f

Mediator-assisted simultaneous probing of cytosolic and mitochondrial redox activity in living cells.

This work describes an electron transfer mediator-assisted amperometric flow injection method for assessing redox enzyme activity in different subcellular compartments of the phosphoglucose isomerase deletion mutant strain of Saccharomyces cerevisiae, EBY44. The method is demonstrated using the ferricyanide-menadione double mediator system to study the effect of dicoumarol, an inhibitor of cytosol

Competitive advantage in the ERP system's value-chain and its influence on future development

Using the resource-based view, we present a set of propositions related to enterprise resource planning (ERP) development, reflections on competitive advantage and the different roles that stakeholders play in the value-chain. This has the goal of building a foundation for future research on ERPs and how stakeholders' desire to achieve competitive advantage influence ERP development, especially wh

Accessibility to the public environment as perceived by teenagers with functional limitations in a south Swedish town centre.

PURPOSE: Owing to physical inaccessibility persons with mobility restrictions and other functional limitations often face problems in public environments, leading to restrictions in activity and participation. To investigate general accessibility and perceived problems of accessibility to the public environment in a town centre, as well as visiting preferences to public facilities, among teenagers

Low frequency of E-cadherin alterations in familial breast cancer

In order to explore the possible role of E-cadherin in familial cancer, 19 familial breast cancer patients, whose tumours demonstrated loss of heterozygosity (LOH) at the E-cadherin locus, were screened for germline mutations. No pathogenic germline alterations were detected in these individuals. However, a somatic mutation was found (49-2A-->C) in one of the tumours. This tumour showed a pattern

Genetic diversity of the epiphytic bryophyte Leucodon sciuroides in formerly glaciated versus nonglaciated parts of Europe

Twelve populations of the epiphytic bryophyte Leucodon sciuroides from three major regions representing formerly glaciated and nonglaciated regions of Europe were screened for polymorphisms at 15 putative isozyme loci. The populations clustered into three distinct groups consisting of: (i) a single population from Crete, representing a cryptic unknown taxon; (ii) four Scandinavian populations and

Role of islet amyloid in type 2 diabetes mellitus: consequence or cause?

Type 2 diabetes mellitus (DM2) is characterized metabolically by defects in both insulin secretion and insulin action, resulting in hyperglycemia. Histopathologically, DM2 is characterized by depositions of protein in the pancreatic islets. This 'islet amyloid' is present in > 90% of patients with DM2, as well as in monkeys and cats with DM2. The pathogenesis of DM2 is heterogeneous and multifacto

Synthesis of amphiphilic amylose and starch derivatives

For non-food uses starch generally is modified in order to obtain products with properties suitable for various applications. In the present work, starch and amylose were hydrophobically modified through reactions with long-chain alpha -alkyl epoxides (C-6 and C-12) in DMSO solution, in the presence of NaH as a catalyst. The molar substitution (MS) was calculated from NMR spectra. Derivatives with

Inverse vs. forward breast IMRT planning

Breast intensity-modulated radiation therapy (IMRT) improves dose distribution homogeneity within the whole breast. Previous publications report the use of inverse or forward dose optimization algorithms. Because the inverse technique is not widely available in commercial treatment planning systems, it is important to compare the 2 algorithms. The goal of this work is to compare them on a prospect

Suppression of cholesterol 7 alpha-hydroxylase transcription and bile acid synthesis by an alpha(1)-antitrypsin peptide via interaction with alpha(1)-fetoprotein transcription factor

alpha(1)-Antitrypsin (alpha(1)-AT) is a serum protease inhibitor that is synthesized mainly in the liver, and its rate of synthesis markedly increases in response to inflammation. This increase in alpha(1)-AT synthesis results in an increase in peptides, like its carboxyl-terminal C-36 peptide (C-36), resulting from alpha(1)-AT cleavage by proteases. Atherosclerosis is a form of chronic inflammati

Coordination of acetate to Al(III) in aqueous solution and at the water-aluminum hydroxide interface: A potentiometric and attenuated total reflectance FTIR study

Attenuated total reflectance FTIR spectroscopy was used to characterize Al(III)-acetate complexation at 25 degrees C, in homogeneous aqueous solution and at the water-aluminum hydroxide interface. The data collected in aqueous solution, at [Al](tot) = 0.080 M, [OAc](tot) = 0.040 M, and pH < 4.3, indicate the presence of only one dominating complex which, by spectral analysis, is shown not to invol

Reproductive effects of male psychologic stress

OBJECTIVES: Male psychologic stress can affect semen quality and couple fecundability. METHODS: We conducted a prospective study of 430 Danish couples who were trying to become pregnant for the first time. In each menstrual cycle, both partners filled out a 12-item version of the General Health Questionnaire (GHQ-12), an assessment of psychologic stress. A blood sample was drawn from both partners

Human papillomavirus and Papanicolaou tests to screen for cervical cancer.

Background Screening for cervical cancer based on testing for human papillomavirus (HPV) increases the sensitivity of detection of high-grade (grade 2 or 3) cervical intraepithelial neoplasia, but whether this gain represents overdiagnosis or protection against future high-grade cervical epithelial neoplasia or cervical cancer is unknown. Methods In a population-based screening program in Sweden,

Telomere dysfunction triggers extensive DNA fragmentation and evolution of complex chromosome abnormalities in human malignant tumors

Although mechanisms for chromosomal instability in tumors have been described in animal and in vitro models, little is known about these processes in man. To explore cytogenetic evolution in human tumors, chromosomal breakpoint profiles were constructed for 102 pancreatic carcinomas and 140 osteosarcomas, two tumor types characterized by extensive genomic instability. Cases with few chromosomal al

The von Willebrand Disease Prophylaxis Network (vWD PN): Exploring a treatment concept.

The von Willebrand Disease Prophylactic Network (vWD PN) has been initiated to study the natural history of vWD bleeding, and to prospectively study the role of von Willebrand Factor (vWF) concentrate prophylaxis in vWD. Patients with all types of vWD in need of treatment with vWF concentrate will be enrolled into the study. Quality of life will be measured and safety and efficacy will be monitore
