The complement system plays an important role in eliminating invading pathogens. Activation of complement results in C3b deposition (opsonization), phagocytosis, anaphylatoxin (C3a, C5a) release, and consequently cell lysis. Moraxella catarrhalis is a human respiratory pathogen commonly found in children with otitis media and in adults with chronic obstructive pulmonary disease. The species has ev

Aim. The aim of this study is to examine associations between caregiver burden, perceived health and sense of coherence in family caregivers to persons with dementia living at home. Background. Most of the studies on family caregivers have focused on burden and morbidity. However, the caregiver's sense of coherence and perceived health have not been studied earlier in relation to caregiver burden.

This article reports model experiments where vocal tract profiles of high and mid unrounded front and high rounded back vowels were systematically modified to simulate small constriction shifts along the hard or soft palate, in order to test A. M. Bell's century-old proposal that small shifts of tongue arch fronting or retraction would yield audible shifts of vowel timbre. Such differences were cl

Rotationally resolved spectral lines in the C-X(1,0) band of carbon monoxide are investigated under high resolution using a coherent vacuum ultraviolet laser source, continuously tunable near 107 nm. Transition frequencies are determined by calibrating against a reference standard of iodine lines, recorded with saturation spectroscopy in the visible range, yielding an absolute accuracy of 0.003 cm

The introduction in 2010 of the Freedom of Choice Act represents one of the most far-reaching reforms of the Swedish health system. While it is mandatory for the regional counties to introduce choice plans for primary care it is voluntary for ambulatory specialist services. The voluntary nature of the regulations for the latter types of care generates a potential gap between the central government

Context: Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are cleaved by dipeptidyl peptidase-4 (DPP-4); plasma activity of DPP-4 may be increased in obesity. The impact of this increase on incretin hormone secretion and metabolism is not known. Objective: The aim of the study was to assess incretin hormone secretion and degradation in lean and obese nondiabet

Several signaling pathways in neurons engage the endoplasmic reticulum (ER) calcium store by triggering calcium release. After release, ER calcium levels must be restored. In many non-neuronal cell types, this is mediated by store-operated calcium entry (SOCE), a cellular homeostatic mechanism that activates specialized store-operated calcium channels (SOC). Although much evidence supports the exi

BACKGROUND: Prostate-specific antigen (PSA) occurs in different molecular forms in serum: free PSA (fPSA) and complexed PSA (cPSA), the sum of which corresponds to total PSA (tPSA). In addition to tPSA, percent fPSA is widely used in the detection of prostate cancer. Free PSA, approximately 28 kDa, is eliminated by glomerular filtration. Previous data showed that men with end-stage renal dysfuncti

Pancreatic beta-cell loss represents a key factor in the pathogenesis of diabetes. Since the influence of purinergic signaling in beta-cell apoptosis has not been much investigated, we examined the role of the ADP receptor P2Y(13) using the pancreatic insulinoma-cell line MIN6c4 as a model system. Real time-PCR revealed high expression of the ADP receptors P2Y(1) and P2Y(13). Adding the ADP analog
