A granulomatous alveolitis, with multinuclear cell formation combined with an eosinophilic peribronchiolitis, was achieved in rats by intratracheal administration of sephadex beads (G-200, Pharmacia, Sweden). The pattern of inflammation and the degree of postgranulomatous fibrosis were substantially dampened when the particles were dispersed by ultrasonification. The animals were analyzed with bro

In the native bovine casein micelle the calcium sensitive caseins (alpha(S1)-, alpha(S2)- and beta-casein) sequester amorphous calcium phosphate in nanometer-sized clusters, whereas the calcium-insensitive K-casein limits the growth of the micelle. In this paper, we further investigate the self-association of kappa- and beta-casein, which are two of the key proteins that control the substructure o

A central tenet of Rescorla and Wagner's model of associative learning is that the reinforcement value of a paired trial diminishes as the associative strength between the presented stimuli increases. Despite its fundamental importance to behavioral sciences, the neural mechanisms underlying the model have not been fully explored. Here, we present findings that, taken together, can explain why a s

Objectives: Angiotensin II (ANGII) is involved in vessel inflammation and is important in the development of cardiovascular disorders such as atherosclerosis. During active disease, patients with granulomatosis with polyangiitis (GPA; Wegener's granulomatosis) have accelerated atherosclerosis and ANGII inhibitors are recommended to these patients to reduce atherosclerosis. We assessed the hypothes

The anaesthetic conserving device (ACD) AnaConDa was developed to allow the reduced use of inhaled agents by conserving exhaled agent and allowing rebreathing. Elevated has been observed in patients when using this ACD, despite tidal volume compensation for the larger apparatus dead space. The aim of the present study was to determine whether CO2, like inhaled anaesthetics, adsorbs to the ACD duri

Surfactants with the cationic functionality based on an amino acid structure have been used to prepare novel biocompatible devices for the controlled encapsulation and release of DNA. We report here the formation of DNA gel particles mixing DNA (either single- (ssDNA) or double-stranded (dsDNA)) with two different single-chain amino acid-based surfactants: arginine-N-lauroyl amide dihydrochloride

Given the cost constraints of the European health-care systems, criteria are needed to decide which genetic services to fund from the public budgets, if not all can be covered. To ensure that high-priority services are available equitably within and across the European countries, a shared set of prioritization criteria would be desirable. A decision process following the accountability for reasona

In this paper, we present a method for metal contact characterization to vertical semiconductor nanowires using the transmission line method (TLM) on a cylindrical geometry. InAs nanowire resistors are fabricated on Si substrates using a hydrogen silsesquioxane (HSQ) spacer between the bottom and top contact. The thickness of the HSQ is defined by the dose of an electron beam lithography step, and

OBJECTIVE: To identify predictors of sick leave and disability pension in patients with early rheumatoid arthritis (RA). METHODS: Individuals aged 19-59 years diagnosed with early RA (≤12 months symptom duration) were identified in the Swedish Rheumatology Quality Register (1999-2007; n=3029). We retrieved days of sick leave and disability pension from the Swedish Social Insurance Agency and basel

To investigate whether interstitial cells (ICs) are present in the adult mouse bladder, and what transmitters characterize adjacent nerve fibres, as ICs in human and guinea-pig bladder lie close to nerve fibres but transmitters present in these nerves have not yet been reported. Sections of the bladder wall from 12 adult male mice (six each, aged 3-4 or 18-24 months) were incubated in carboxygenat

The present study was designed to demonstrate a hypothesis that some G-protein coupled receptors are up-regulated and a dysfunction of endothelium occurs in hypertension. The arteries from hypertensive patients and spontaneously hypertensive rats (SHR) were tested. An in vitro myograph system was used to obtain concentration-contraction curves mediated by endothelin ETA, endothelin ETB, 5-hydroxyt

Objective To assess the application of a quality control scheme for total prostate-specific antigen (PSA) as used for participants of the European Randomized Study for Screening of Prostate Cancer (ERSPC) during 1996-2002. Methods From 1996, the first complete year being 1997, an external scheme was organized by the Dutch Quality Assessment Foundation especially for the ERSPC. This scheme consists

Introduction: Identification of suitable candidates for cardioversion currently is not based on individual electrical and mechanical atrial remodeling. Therefore, this study analyzed the meaning of atrial fibrillatory rate obtained from the surface ECG (as a measure of electrical remodeling) and left atrial size (as measure of mechanical remodeling) for prediction of early atrial fibrillation (AF)

The adsorption of starch that had been hydrophobically modified with octenyl succinate anhydride (OSA) at the oil/water interface during emulsification was studied. The starch samples were of waxy barley origin and were varied in molar mass and degree of substitution (DS). The particle size of the emulsions was measured and the adsorbed amount of starch was determined through serum depletion. The

Abstract Aim: Compared to neutral globular proteins, neutral polysaccharides, such as dextran, pullulan and Ficoll, appear hyperpermeable across the glomerular filtration barrier. This has been attributed to an increased flexibility and/or asymmetry of polysaccharides. The present study investigates whether polysaccharides are hyperpermeable also across the continuous capillaries in the rat perito

Purpose: To describe, by use of a phenomenological approach, how relatively young trans-femoral amputees experienced their amputation and their coping strategies in the acute phase and over time. Method: Eleven trans-femoral amputees, median age 33.5 years, were interviewed. The amputation was caused by tumour, motorcycle accidents or work-related traumas. Amputation was made in median 7.5 years

Objective: The purpose of the study was to determine if a dose-response relationship exists between obstetric adversity and age at first presentation with schizophrenia. Method: The Dublin Psychiatric Case Register was used to identify subjects with schizophrenia. Data on obstetric complications, social class of origin, and family history of psychiatric illness were obtained for those subjects. Re
