Proenkephalin-A mRNA is widely expressed in tissues of the human gastrointestinal tract

Background: It has been shown that the non-opioid effects of Met-enkephalin, which is derived from proenkephalin-A, are mediated through a specific opioid growth factor (OGF) receptor which is assumed to be involved in the control of cell growth. The expression and tissue location of proenkephalin-A mRNA in the gastrointestinal tract remains largely unknown. Methods: In this study we have analyzed

Pseudomonas aeruginosa-induced infection and degradation of human wound fluid and skin proteins ex vivo are eradicated by a synthetic cationic polymer

Objectives: Antimicrobial peptides are important effectors of innate immunity. Bacteria display multiple defence mechanisms against these peptides. For example, Pseudomonas aeruginosa releases potent proteinases that inactivate the human cathelicidin LL-37. Hence, in conditions characterized by persistent bacterial colonization, such as in P. aeruginosa-infected skin wounds, there is a need for ef

Registries of immunodeficiency patients and mutations

Immunodeficiencies form a distinct group of human hereditary diseases with several rare disorders. During recent years, information has been collected concerning immunodeficiency patients and mutations causing disorders. The large European (ESID) registry contains clinical data for some 7,000 patients. At present, international mutation databases have information for > 1,000 immunodeficiency patie

Reversible size of shear-induced multi-lamellar vesicles

We have investigated the reversibility in the shear-induced multi-lamellar vesicle (MLV) size during stepwise cycling of the shear rate by employing common rheometry, polarized light microscopy and rheo-optic techniques. We thus address the question whether there is a true MLV steady state, irrespective of history. The system studied, was the nonionic surfactant triethylene glycol decyl ether (C10

Cartilage oligomeric matrix protein-deficient mice have normal skeletal development.

Cartilage oligomeric matrix protein (COMP) belongs to the thrombospondin family and is a homopentamer primarily expressed in cartilage. Mutations in the COMP gene result in the autosomal dominant chondrodysplasias pseudoachondroplasia (PSACH) and some types of multiple epiphyseal dysplasia (MED), which are characterized by mild to severe short-limb dwarfism and early-onset osteoarthritis. We have

Thermo gravimetric study of calcination of dolomite at pressurised conditions

Calcination and carbonation behaviour of dolomite has been studied in a pressurised thermo balance at pressures in the range of 1.1 to 2.3 MPa and for temperatures ranging from 730 to 840 degrees C. The atmosphere consisted of nitrogen containing up to 20 vol.-% carbon dioxide. The calcination of dolomite has been studied as a function of temperature, particle size, and P-CO2. An investigation con

Fetal varicella-herpes zoster syndrome in early pregnancy: ultrasonographic and morphological correlation

We report a case of an intrauterine fetal infection by the varicella-herpes zoster virus following maternal varicella at 17 weeks' amenorrhea. Prenatal diagnosis of fetal infection was confirmed by serology and fetal damage by ultrasonography. Autopsy of the fetus showed multiorgan manifestation with disseminated foci of necrosis and microcalcifications, encephalitis and unilateral segmental skin

Chemical composition and morphology of individual aerosol particles from a CARIBIC flight at 10 km altitude between 50 degrees N and 30 degrees S

Analysis of individual particles by analytical electron microscopy as well as quantitative analysis using particle-induced X-ray emission (PIXE) and particle elastic scattering analysis (PESA) were carried out on samples collected from a flight at 10 km altitude between 50 degrees N and 30 degrees S as part of the Civil Aircraft for Regular Investigation of the atmosphere Based on an Instrument Co

Nu startar projekt Skånes Mossor!

The Lund Botanical Society 2007-03-23 decided to launch a project with the following aims: 1) to map the frequency and distribution of all bryophytes in the province of Skåne, southernmost Sweden, thereby making way for future studies of changes in the flora, 2) to find and document as many sites as possible for nationally and regionally rare or endangered bryophytes and initiate conservation acti

Coupled diffusion and adsorption effects for multiple proteins in agarose gel

A mathematical model for the hindered diffusion and competitive adsorption of two proteins in an agarose gel has been developed. In a simulation program the model has been used to study the competing and displacement effects on a single bead for lysozyme and bovine serum albumin (BSA) bound to the ligand Cibacron Blue in agarose gel. The model takes into account hindered diffusion described by the

Delayed recombination of detrapped space-charge carriers in poly[2-methoxy-5-(2 '-ethyl-hexyloxy)-1,4-phenylene vinylene]-based light-emitting diode

We report the observation of a spectroscopically resolved delayed electrofluorescence (DEF) in the time domain of nanosecond to microsecond (depending on temperature, in the range of 30-290 K, as well as bias) from light-emitting diodes based on poly[2-methoxy-5-(2(')-ethyl-hexyloxy)-1,4-phenylene vinylene]. The decay kinetics of this DEF are always found to be biexponential in nature. The fast de

Identification of T1D susceptibility genes within the MHC region by combining protein interaction networks and SNP genotyping data

To develop novel methods for identifying new genes that contribute to the risk of developing type 1 diabetes within the Major Histocompatibility Complex (MHC) region on chromosome 6, independently of the known linkage disequilibrium (LD) between human leucocyte antigen (HLA)-DRB1, -DQA1, -DQB1 genes. We have developed a novel method that combines single nucleotide polymorphism (SNP) genotyping dat

Contribution of mitral annular excursion and shape dynamics to total left ventricular volume change

The mitral annulus (MA) has a complex shape and motion, and its excursion has been correlated to left ventricular (LV) function. During the cardiac cycle the annulus' excursion encompasses a volume that is part of the total LV volume change during both filling and emptying. Our objective was to evaluate the contribution of MA excursion and shape variation to total LV volume change. Nine healthy su

Treatment and vision-related quality of life in the early manifest glaucoma trial

Purpose: To evaluate the effect of treatment, visual function, and other factors on vision-targeted health-related quality of life (HRQOL) of patients with early glaucoma. Design: Randomized clinical trial. Participants: Two hundred fifty-five patients with newly detected open-angle glaucoma and repeatable early visual field (VF) defects, 50 to 80 years old (66% female). Methods: Patients were ran

Long-range PCR facilitates the identification of PMS2-specific mutations

Mutations within the DNA mismatch repair gene, "postmeiotic segregation increased 2" (PMS2), have been associated with a predisposition to hereditary nonpolyposis colorectal cancer (HNPCC; Lynch syndrome). The presence of a large family of highly homologous PMS2 pseudogenes has made previous attempts to sequence PMS2 very difficult. Here, we describe a novel method that utilizes long-range PCR as

5-Hydroxytryptamine stimulates the formation of inositol phosphate in astrocytes from different regions of the brain

5-Hydroxytryptamine (5-HT) stimulated the turnover of phosphoinositide in primary cultures of astroglia from the cerebral cortex, striatum, hippocampus and brain stem. Ketanserin and ritanserin, selective antagonists for the central 5-HT2 receptor, inhibited the 5-HT-stimulated formation of inositol monophosphate. In contrast, there was no statistically significant accumulation of cyclic AMP after

Multi-species ionic diffusion in concrete with account to interaction between ions in the pore solution and the cement hydrates

The penetration and leaching of ionic species in concrete are studied by using a model based on the Nernst-Planck equations. A finite element procedure is used to solve the coupled non-linear governing equations. A numerical example is performed in which the results are compared to measured electron probe micro analysis (EPMA) data. A close agreement of the simulated results to measured data is fo
