The aim of this study was to evaluate the effects of a novel antimuscarinic agent, Lu 25-109, a partial M1 receptor agonist, and M2/M3 receptor antagonist in human and pig detrusor to establish its affinity for muscarinic receptors in human detrusor and parotid gland and to compare the results with those obtained with oxybutynin. Effects on the detrusor were determined as regards the ability to in

Two patients with long-term (35 years) survival on hemodialysis are described. Kidney replacement therapy for these patients was initiated by a pioneer in hemodialysis, Nils Alwall, in 1968 and 1971, respectively. Kidney transplantation was attempted twice in both patients; however, the dialysis-free interval was less than 18 months in both patients. These patients represent two of the longest kno

Coronene is a highly symmetric organic molecule whose molecular structure resembles a fragment of graphite. We have crystallized a charge-transfer complex based on coronene and TCNQ, and present crystal structure and transport properties. The complex adopts alternate stacking between coronene and TCNQ and the charge-transfer was estimated to be of the order of 0.3 by the structure and IR analysis

BACKGROUND: There is a wide range (5-50 per 100 000) in the reported annual incidence of acute pancreatitis. Furthermore, the predominant aetiology varies in different reports. This study was undertaken to establish the current incidence, aetiology and associated mortality rate in a defined population. METHODS: A retrospective study of all cases of acute pancreatitis admitted over a 10-year p

Cost reduction strategies are often invoked as explanations when studies of adaptation fail to find predicted costs. This might seem discouraging, offering little opportunity for further investigation. In this paper, we demonstrate that cost reduction strategies can themselves be investigated by arguments from design. Recent work on inducible morphological defences has shown that hydrodynamical di

Quaternary glacial stratigraphy and relative sea-level changes reveal at least four expansions of the Kara Sea ice sheet over the Severnaya Zemlya Archipelago at 79 degrees N in the Russian Arctic, as indicated from tills interbedded with marine sediments, exposed in stratigraphic superposition, and from raised-beach sequences that occur at altitudes up to 140 m a.s.l. Chronologic control is provi

We investigated differences in smoking prevalence between urban and non-urban area of residence in six Western European countries (Sweden, Finland, Denmark, Germany, Italy and Spain), and smoking prevalence trends over the period 1985-2000. In most countries, smoking prevalence was highest in urban areas, and increased with urbanization. Urban/non-urban inequalities were most pronounced among indi

We developed a technique for studying seasonal and interannual variation in pyrogenic carbon emissions from Africa using a modelling approach that scales burned area estimates from L3JRC, a map recently generated from remote sensing of burn scars instead of active fires. Carbon fluxes were calculated by the novel fire model SPITFIRE embedded within the dynamic vegetation model framework LPJ-GUESS,

OBJECTIVES: The present study tested the hypothesis that treatment with human recombinant immunoglobulin G1 (IgG1) antibodies against a specific oxidized low-density lipoprotein (oxLDL) epitope will induce regression of existing atherosclerotic lesions in LDL receptor-deficient mice expressing apolipoprotein B-100 (apoB-100) (Apobec-1(-/-)/LDLR(-/-)). BACKGROUND: Oxidized LDL plays an essential ro

Objective. Our study describes sick leave during 3 years before and 3 years after diagnosis of rheumatoid arthritis (RA) in relation to referents and identifies predictors for sick leave during the third year after diagnosis of RA. Methods. One hundred twenty patients (76% women) from the Swedish early RA study TIRA were included. Disease activity and disability were registered regularly during 3

Patterns of variation among all micro-species of Hieracium sect. Hieracium and H. sect. Vulgata known from Denmark and southern Sweden are investigated. Forty-three, possibly independent morphological characters are used. Significant correlations were revealed among the majority of the characters. Multivariate analyses did not reveal any discontinuities in the variation or any discrete groups of s

BACKGROUND: Formation of intra-abdominal adhesions depends, in part, on the activity of serine proteinases. Matrix metalloproteinases (MMP) are required for epithelialization of skin wounds but their involvement in mesothelialization of peritoneal wounds and in adhesion pathogenesis is not known. Early tumor necrosis factor-alpha (TNF-alpha) levels have been proposed to reflect propensity to adhes

The standard method for measuring the it umber of infectious phages in solution has traditionally been the plaque forming assay. An alternative method is described where the number of lytic, infectious phages is determined in an endpoint titration assay adapted for a microplate system. In this model system, susceptible Escherichia coli 136 at a density of 4 x 10(7) cells/ml, were mixed with an equ

Postmitotic neurons were generated from the human NT-2 teratocarcinoma cell line in a novel rapid differentiation procedure. These neurons were used to establish an in vitro assay system that allows the investigation of hypoxic/ischaemic cell damage and the development of neuroprotective strategies. In experiments of simulated ischaemia, the neurons were subjected to anoxia and hypoglycaemia. The

Instability of the pre-ocular tear film causes symptoms of dry eyes. Tear film instability may be caused by exposure to air pollutants, but identification of causative agents is often difficult. We describe an in vitro technique for assessment of putative agents on the surface activity of Meibomian lipids. The lipids were obtained from bovine eyelids and dissolved in chloroform. Surface activity o

Leukotriene ( LT) A(4) hydrolase is a bifunctional zinc metalloenzyme, which converts LTA(4) into the neutrophil chemoattractant LTB4 and also exhibits an anion-dependent aminopeptidase activity. In the x-ray crystal structure of LTA(4) hydrolase, Arg(563) and Lys(565) are found at the entrance of the active center. Here we report that replacement of Arg(563), but not Lys(565), leads to complete a

Temperate and boreal forests in the Northern Hemisphere cover an area of about 2 times 107 square kilometres and act as a substantial carbon sink (0.6–0.7 petagrams of carbon per year)1. Although forest expansion following agricultural abandonment is certainly responsible for an important fraction of this carbon sink activity, the additional effects on the carbon balance of established forests of

A conjugated polymer with a low band gap of 1.21 eV, i.e., absorbing infrared light, is demonstrated as active material in field-effect transistors (FETs). The material consists of alternating fluorene units and low band gap segments with electron donor-acceptor-donor units composed of two electron-donating thiophene rings attached on both sides of a thiadiazolo-quinoxaline electron-acceptor group
