Carbon monoxide-induced relaxation and distribution of haem oxygenase isoenzymes in the pig urethra and lower oesophagogastric junction

1. The distribution of the carbon monoxide (CO) producing enzymes haem oxygenase (HO)-1 and -2 was studied by immunohistochemistry in the pig's lower urinary tract, including bladder extramural arteries, and the oesophagogastric junction (OGJ). In isolated smooth muscle from the urethra and the OGJ, the mechanisms for CO-induced relaxations were characterized by measurement of cyclic nucleotide le

Low serum level of soluble tumor necrosis factor receptor p55 predicts response to thalidomide in advanced multiple myeloma

Background and Objectives. Thalidomide modulates the production of tumor necrosis factor (TNF-alpha). Soluble TNF receptors, TNFR p55 and TNFR p75, modify TNF-a activity. In this study, we explored the relation between soluble TNF receptors and outcome in patients with advanced multiple myeloma treated with thalidomide. Design and Methods. The levels of soluble TNF receptor p55 and p75 were assess

Monotone operator functions on C*-algebras

The article is devoted to investigation of classes of functions monotone as functions on general C-*-algebras that are not necessarily the C-*-algebra of all bounded linear operators on a Hilbert space as in classical case of matrix and operator monotone functions. We show that for general C-*-algebras the classes of monotone functions coincide with the standard classes of matrix and operator mono

Atrial fibrillation and flutter: aeromedical considerations. New strategies for management and intervention

Few cases of atrial fibrillation can be completely excused from the possibility of having some impact of potential importance in the aviation environment. The clinical pattern in paroxysmal disturbance is very wide and possible incapacitating phenomena are mainly haemodynamic. In contrast, chronic atrial fibrillation is mostly well-tolerated with only minimal haemodynamic effect, but there is a ri

Fuktdimensionering av träkonstruktioner : riskanalys

Denna rapport syftar till att anvisa metoder för att beräkna eller bedöma risken för fuktskador, särskilt i träkonstruktioner. I rapporten ingår en allmän orientering i riskanalys, statistiska beräkningar enligt Monte Carlo-metoden samt andra beräkningar av riskfaktorer gällande fukt- och mögelangrepp.

Exposure of infants to budesonide through breast milk of asthmatic mothers

Background: Maintenance treatment with inhaled corticosteroids is often required for asthmatic nursing women. Data on the transfer of inhaled corticosteroids from plasma to breast milk and the subsequent exposure of the breast-feeding infant has been unavailable. Objective: We sought to assess budesonide concentrations in milk and plasma of asthmatic nursing women receiving maintenance treatment w

Taking automatic control into wood ash recycling

In Sweden, extensive research is conducted to find alternative sources of energy that should partly replace the electric power production from nuclear power. With the ambition to create a sustainable system for producing energy, the use of renewable energy is expected to grow further and biofuels are expected to account for a significant part of this increase. However, when biofuels are burned or

Role of surface diffusion in chemical beam epitaxy of InAs nanowires

We present growth studies of InAs nanowires nucleated from lithographically positioned Au seeds on InAs (111)B substrates. The nanowires are grown in a chemical beam epitaxy system and exhibit high aspect ratios and high homogeneity in length and width. Investigations of wire growth rate as a function of diameter, density, and time were performed and the results indicate that 80% of the growth is

Imperiet slås tillbaka?

Globaliseringsrörelsen har observerats allt mer. Men den består inte av en rörelse utan av flera. I samband med rapporteringen från Göteborg och Genua har också den nya boken ”Empire” uppmärksammats. Boken försöker fånga den anda som driver globaliseringsrörelsen framåt och de politiska rörelser som politiserar denna process.

A Swedish Perspective on the Prevention of Moisture Problems During the Building's Design Phase

Moisture problems in buildings are increasingly being reported in the mass media in Sweden, often leading to some controversial stories about companies and their building processes. Using building physics and building performance principles during the design stage can often prevent most problems from occurring. One of the big questions is, with all the available knowledge about designing a buildin

Stratum corneum hydration: phase transformations and mobility in stratum corneum, extracted lipids and isolated corneocytes

The outermost layer of skin, stratum corneum (SC), functions as the major barrier to diffusion. SC has the architecture of dead keratin filled cells embedded in a lipid matrix. This work presents a detailed study of the hydration process in extracted SC lipids, isolated corneocytes and intact SC. Using isothermal sorption microcalorimetry and relaxation and wideline 1H NMR, we study these systems

Shape, shell structure and collective modes unique to nuclei far from stability line

The structure of nuclei far from beta-stability lines is expected to show various interesting and exotic phenomena, due to the unique features: (a) the presence of nucleons with very small binding energies and largely extended wave-functions; (b) large difference between the Fermi levels of protons and neutrons; (c) exotic ratios of the proton to neutron numbers for a given mass number. Among the

Evaluation of new methods for the monitoring of alkalinity dissolved hydrogen and the microbial community in anaerobic digestion

New methods for spectrophotometric alkalinity measurement, dissolved hydrogen monitoring and for obtaining a fingerprint of the microbial community were evaluated as tools for process monitoring in anaerobic digestion. The anaerobic digestion process was operated at organic loading rates of 1.5, 3.0 and 4.5g volatile solids l-1d-1 and subjected to pulse loads of carbohydrate, lipid, protein and a
