Background: The main purpose for measuring urinary free sialic acid (FSA) is to diagnose sialic acid (SA) storage diseases. Elevated amounts of conjugated sialic acid (CSA) are observed in several diseases indicating the need to quantify CSA as well. A LC-MS/MS method for quantification of FSA and total sialic acid (TSA) in urine is developed and validated. Methods: FSA is analyzed directly after
Background Some evidence suggests that chronic kidney disease is a risk factor for lower-extremity peripheral artery disease. We aimed to quantify the independent and joint associations of two measures of chronic kidney disease (estimated glomerular filtration rate [eGFR] and albuminuria) with the incidence of peripheral artery disease. Methods In this collaborative meta-analysis of international
Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive tumors, accounting for around 5% of all soft tissue sarcomas. A better understanding of the pathogenesis of these tumors and the development of effective treatments are needed. In this context, established tumor cell lines can be very informative, as they may be used for in-depth molecular analyses and improvement of treatment strate
Food additives such as emulsifiers are used in increasing quantities in the food industry. The aim of this study was to compare three different emulsifiers (polysorbate 80 (P80), carboxymethyl cellulose (CMC), and β-lactoglobulin (β-lac) with regards to their effect on the stimulation of immune cells and intestinal permeability. The immune stimulatory effects were studied in the myeloid cell line
BACKGROUND. We investigated the association of different subfractions of prostate specific antigen (PSA) and human glandular kallikrein 2 (hK2), such as total PSA (tPSA), complexed PSA (cPSA), free PSA (fPSA), "single-chain Intact fPSA" (fPSA-I), "multi-chain nicked fPSA" (fPSA-N), and total hK2 with volumes of total prostate gland, transition zone (tz), and prostate cancer (PCa) tissue in patient
Using the newly described streptococcal surface protein, protein G, which has powerful immunoglobulin G binding properties, solid-phase radioimmunoassays were developed for the quantitation of goat and rat immunoglobulin G bound to the plastic surface of microtiter plates. The binding of goat immunoglobulin G to the surface via a specific antigen (guinea pig alpha 1-microglobulin) permitted the de
Obesity impairs the relaxant capacity of adipose tissue surrounding the vasculature (PVAT) and has been implicated in resultant obesity-related hypertension and impaired glucose intolerance. Resident immune cells are thought to regulate adipocyte activity. We investigated the role of eosinophils in mediating normal PVAT function. Healthy PVAT elicits an anti-contractile effect, which was lost in m
Radiological evaluation of incidentally detected lung nodules on computed tomography (CT) influences management. We assessed international radiological variation in 1) pulmonary nodule characterisation; 2) hypothetical guideline-derived management; and 3) radiologists' management recommendations.107 radiologists from 25 countries evaluated 69 CT-detected nodules, recording: 1) first-choice composi
When decision on repair has been taken the available repair systems/methods must be evaluated with regard to the immediate requirements. For each type and cause of damage, there are normally only a few possible repair systems. These repair systems should be evaluated with regard to following 5 basic properties, or characteristics: 1) service life/durability, 2) structural stability/safety, 3) exec
A proposal for a new synchrotron light source, MAX 4, is presented. The main components are two identical storage rings operated at different electron beam energies and equipped with superconducting insertion devices. Small beam emittances will yield high brilliance radiation over a wide spectral range. A small horizontal emittance is achieved by using a large number of cells with gradient dipoles
We performed transient absorption (TA) measurements on CP29 minor light-harvesting complexes that were reconstituted in vitro with either violaxanthin (Vio) or zeaxanthin (Zea) and demonstrate that the Zea-bound CP29 complexes exhibit charge-transfer (CT) quenching that has been correlated with the energy-dependent quenching (qE) in higher plants. Simulations of the difference TA kinetics reveal t
Collagen-induced arthritis (CIA) is one of the most commonly used animal models for Rheumatoid arthritis (RA). CIA is induced in susceptible mouse strains after immunization with heterologous type II collagen (CII). In mice of the H-2q haplotype rat CII (rCII) is used whereas in mice of the H-2r haplotype bovine CII is utilized. The broad objective of this thesis was to gain an understanding of th
Popular Abstract in Swedish Syftet med denna avhandling är att studera den sydhalländska stickningsindustrins framväxt, utveckling och organisation under tidigmodern tid. Denna protoindustriella verksamhet bedrevs i godsbygd i huvudsak på förlagsbasis. Tidigt spelade Wallens gods i Våxtorps socken en aktiv roll i verksamheten. Under 1700-talets senare hälft organiserades stickningsindustrin av förThe aim of this dissertation has been to examine the growth, development, and organisation of the knitting industry in southern Halland during early modern times. This proto-industrial enterprise was conducted primarily via a putting-out system in the goods districts. Wallen's estate in Våxtorp parish played an active role in the enterprise already from an early stage. During the latter half of th
BACKGROUND: BRCA1 and BRCA2 are the two major susceptibility genes involved in hereditary breast cancer. This study was undertaken to provide reliable population-based estimates of genetic influence and to characterize the nature and prevalence of BRCA1 and BRCA2 germline mutations in early-onset breast cancer.METHODS: In a series comprising all women diagnosed with breast cancer under the age of
Neisseria meningitidis lipopolysaccharide (LPS) has been identified as a major determinant of dendritic cell (DC) function. Here we report that one of a series of meningococcal mutants with defined truncations in the lacto-N-neotetraose outer core of the LPS exhibited unique strong adhesion and internalization properties towards DC. These properties were mediated by interaction of the GlcNAc(beta1
An outbreak of gastroenteritis affecting 158 of 219 (72%) guests and employees at a hotel is described. Food served at the hotel restaurant is believed to have been the source of the outbreak and to have been contaminated by sick employees working in the restaurant. A secondary attack rate of 22% was seen involving 43 persons in all. In stool specimens from seven of eight patients, Norwalk-like vi
Specific causes of death, survival, and recurrence rates were assessed in a cohort of 60 patients who had undergone surgery for craniopharyngioma between 1951 and 1988. Compared to the general population, the standardized mortality ratio (SMR) was increased [5.55; 95% confidence interval (CI), 3.68-8.22], and it was higher among females (SMR, 11.4) than males (SMR, 4.79). The risk of cardio- and c
Gram-negative bacteria from the genus Acinetobacter are responsible for life-threating hospital-related infections such as pneumonia, septicemia, and meningitis, especially in immunocompromised patients. Worryingly, Acinetobacter have become multi- and extensively drug resistant (MDR/XDR) over the last few decades. The complement system is the first line of defense against microbes, thus it is hig
