Copper allergy from dental copper amalgam?

A 65-year-old female was investigated due to a gradually increasing greenish colour change of her plastic dental splint, which she used to prevent teeth grinding when sleeping. Furthermore, she had noted a greenish/bluish colour change on the back of her black gloves, which she used to wipe her tears away while walking outdoors. The investigation revealed that the patient had a contact allergy to

A wideband spatial channel model for system-wide simulations

A wideband space-time channel model is defined, which captures the multiple dependencies and variability in multicell system-wide operating environments. The model provides a unified, treatment of spatial and temporal parameters, giving their statistical description and dependencies across a large geographical area for three outdoor environments pertinent to third-generation cellular system simula

Polymer recycling in aqueous two-phase extractions using thermoseparating ethylene oxide-propylene oxide copolymers

This is a study on the recovery and recycling of copolymer in aqueous two-phase systems containing random copolymers of ethylene oxide (EO) and propylene oxide (PO). The random copolymers separate from water solution when heated above the lower critical solution temperature (LCST). The primary phase systems were composed of EOPO copolymer and hydroxypropyl or hydroxyethyl starch. After phase separ

Epitope mapping of anti-glomerular basement membrane (GBM) antibodies with synthetic peptides

Autoantibodies to the non-collagenous (NC1) domain of the alpha 3(IV)-chain of type IV collagen are found in sera from patients with anti-GBM nephritis. These antibodies have been shown to be pathogenic. In this study the antibody specificity has been investigated in patients with Goodpasture's syndrome and from a patient with atypical anti-GBM antibodies, recognizing the alpha 1(IV)-chain only. O

Correlation between different intensities of anti-vitamin K treatment and coagulation parameters

In order to study the effect of different intensities of anti-vitamin K treatment on coagulation parameters, 23 patients with venous thromboembolism were given, after the initial treatment period, warfarin at doses giving an International Normalised Ratio of 1.3-2.0 for 4 weeks, and of 1.1-1.3 for another 4 weeks. Blood samples were taken at the end of each of these periods and 4 weeks after the e

The proportion of carboxylated to total or intact osteocalcin in serum discriminates warfarin-treated patients from control subjects

We assessed the serum concentration of gamma-carboxylated osteocalcin (OC), total OC, and full-length OC in a clinical setting of 37 patients on continuous warfarin treatment (international normalized ratio 2.0-3.8). A comparison was done with the results from 30 untreated age-matched controls. Four monoclonal antibodies, previously generated and characterized as to their ability to recognize diff

Class-A lasers with injected signal: Bifurcation set and Lyapunov-potential function

We describe the bifurcation set for a class-A laser with an external injected signal in terms of the amplitude and the frequency of the applied field. We explain the dynamical behavior of this kind of lasers in terms of a Lyapunov potential in the case where such a description is possible. In particular, a full description for the deterministic and nondeterministic dynamics can be given by using t

Differences in lodgement of tumour cells in muscle and liver

Differences in the lodgement of circulating tumour cells in various organs are considered an important factor in metastatic organ selection. The present vital microscopic studies show that the pattern of intravascular arrest of tumour cells in muscle after intra-arterial injection is similar to that observed earlier, in the liver, after intraportal injection. However, parallel isotope studies on t

Polydispersity and heterogeneity of squid cranial cartilage proteoglycans as assessed by immunochemical methods and electron microscopy

The three populations of squid cranial cartilage proteoglycans, D1D1A, D1D1B and D1D2 appeared to have a high degree of polydispersity. Gel electrophoresis and immunoblotting analysis showed that polydispersity was mainly due to the variable size of chondroitin sulphate E chains. This was further ascertained after rotary shadowing electron microscopy of proteoglycan core proteins and glycosaminogl

Diet and endogenous carbohydrases in the temperate marine herbivorous fish Kyphosus sydneyanus

Stomach content analysis showed that Kyphosus sydneyanus collected by spearing from coastal reefs near Leigh, north-east New Zealand, is herbivorous throughout its post-settlement life. All size classes collected consumed a wide range of macroalgae, predominantly the phaeophytes Carpophyllum maschalocarpum and Ecklonia radiata, and the rhodophytes Gigartina macrocarpa and Caulacanthus ustulatus. M

Diffusion and perfusion MRI in patients with ruptured and unruptured intracranial aneurysms treated by endovascular coiling: complications, procedural results, MR findings and clinical outcome.

Our purpose was to evaluate treatment safety as well as complications frequency and management in endovascular coiling of intracerebral aneurysms using MR diffusion and perfusion imaging. In this prospective study, 77 MR examinations were performed in conjunction with 43 procedures in 40 patients, 14 patients presented with ruptured and 26 with unruptured aneurysms. Mean time interval between trea

Identification of oxidative stress and toll-like receptor 4 signaling as a key pathway of acute lung injury

Multiple lung pathogens such as chemical agents, H5N1 avian flu, or SARS cause high lethality due to acute respiratory distress syndrome. Here we report that Toll-like receptor 4 (TLR4) mutant mice display natural resistance to acid-induced acute lung injury (ALI). We show that TLR4-TRIF-TRAF6 signaling is a key disease pathway that controls the severity of ALI. The oxidized phospholipid (OxPL) Ox

A polymorphism in the serotonin receptor 3A (HTR3A) gene and its association with harm avoidance in women

BACKGROUND: The brain neurotransmitter serotonin is known to affect various aspects of human behavior, including personality traits. Serotonin receptor type 3 is a ligand-gated channel encoded by 2 different subunit genes, HTR3A and HTR3B. A polymorphism (C178T) in the 5' region of the HTR3A gene has recently been identified and suggested to be of functional importance. OBJECTIVE: To elucidate the

Electrical properties of InAs-based nanowires

Semiconductor nanowires are grown using chemical beam epitaxy and metal organic vapor phase epitaxy from size-selected gold nanoparticles acting as catalysts. By changing materials during the growth it is possible to form heterostructures both along the length of the nanowires but also in a core-shell fashion. In particular, incorporation of pairs of InP tunnel barriers in InAs nanowires has been

Fertility and history of sexual abuse at 10-year follow-up of adolescent-onset anorexia nervosa

Objective We studied fertility and history of child sexual abuse (CSA) in a representative group of anorexia nervosa (AN) cases. Method Fifty-one adolescent-onset AN cases recruited after community screening and 51 matched comparison cases were interviewed 10 years after reported AN onset, at mean age 24 years, regarding children, miscarriages, and fertility problems. They completed anonymousl

Identification of the site on IgG Fc for interaction with streptococci of groups A, C and G

The interaction between living groups A, C and G streptococci and IgG Fc was studied using human IgG, IgG Fc and IgG Fc-intermediate (Fci) fragments, chemically modified human IgG and fragment D of staphylococcal protein A (SPA). Diethylpyrocarbonate modification of His or N-acetylimidazole modification of Tyr of human IgG resulted in the loss of its capacity to inhibit the binding of radiolabelle

Microbial manipulation of the rat dam changes bacterial colonization and alters properties of the gut in her offspring.

The impact of an altered bacterial colonization on gut development has not been thoroughly studied, despite the increased risk of certain diseases with a disturbed microbiota after birth. This study was conducted to determine the effect of microbial manipulation, i.e. antibiotic treatment or Escherichia coli (E. coli) exposure, of the dam on bacterial colonization and gut development in the offspr
