Prevention of postoperative peritoneal adhesions: Effects of lysozyme, polylysine and polyglutamate versus hyaluronic acid

Objective. Intraperitoneal adhesions are an important cause of postoperative intestinal obstruction, abdominal discomfort and infertility. In the present study we hypothesized that a combination of polypeptides with different surface properties, resulting in fine disperse low-soluble complexes, could be of benefit in the prevention of abdominal adhesions. Material and methods. Various polypeptides

Ultrafast carotenoid band shifts: Experiment and theory

The ultrafast carotenoid band shift upon excitation of nearby bacteriochlorophyll molecules was studied in three different light harvesting complexes from purple bacteria. The results were analyzed in terms of changes in local electric field of the carotenoids. Time dependent density functional theory calculations based on known and model structures led to good agreement with experimental results,

Cost-analyzes based on a prospective, randomized study comparing laparoscopic colposuspension with a tension-free vaginal tape procedure.

Background. The aim of this study was to compare laparoscopic colposuspension with tension-free vaginal tape (TVT) in terms of costs to the county. Methods. In a prospective, randomized study, we approached 270 consecutive women presenting for evaluation of stress urinary incontinence symptoms at one university hospital. Preoperatively, and at 1-year follow-up, the women underwent urodynamic eval

Impaired postural control in patients with cervico-brachial pain

Dizziness and subjective balance disturbances are common complaints in cervical pain syndromes. We assessed balance function with posturography using vibration-induced and galvanically-induced body sway in consecutive patients (n = 116) with cervico-brachial pain syndrome of more than 3 months' duration. A total of 83% of the patients showed signs of cervical root compression on MRT scans. The inc

Ultra short-loop feedback control of thyrotropin secretion

Evidence is accumulating that pituitary hormone secretion is not only regulated by feedback from hormones produced in the target organs (long feedback) on the pituitary and the hypothalamus (feedforward), but also by a feedback of the hypophyseal hormones at the hypothalamic (short feedback) and the pituitary (ultra-short feedback) level. Inhibition of thyrotropin (TSH) and MSH secretion by pituit

The role of molecular polarity in cluster local structure studied by photoelectron spectroscopy

We have studied the spatial structure and electronic levels of clusters of the molecule CH3Br to investigate the effects of molecular polarity on these properties. Analysis of the core level photoclectron spectra of initially neutral CH3Br clusters shows that the C 1 s(-1) state has a 30% larger binding energy shift between free molecules and clusters than the Br 3d(-1) state. This difference is a

JJGEN: A flexible program for generating lists of j j-coupled configuration state functions

The success of large scale relativistic multiconfiguration Dirac-Hartree-Fock calculations for atomic systems rely on judiciously chosen configuration expansions. Dependent on the atomic system as well as on the studied properties, various correlation effects need to be considered. Based on the active set approach, this program allows the user to generate general lists of j j-coupled configuration

A hedging point strategy - balancing effluent quality, economy and robustness in the control of wastewater treatment plants

An operational space map is an efficient tool to compare a large number of operational strategies to find an optimal choice of setpoints based on a multicriterion. Typically, such a multicriterion includes a weighted sum of cost of operation and effluent quality. Due to the relative high cost of aeration such a definition of optimality result in a relatively high fraction of the effluent total nit

Transient waves from internal sources in non-stationary media - Numerical implementation

In this paper, the focus is on numerical results from calculations of scattered direct waves, originating from internal sources in non-stationary, dispersive, stratified media. The mathematical starting point is a general, inhomogeneous, linear, first order, 2 × 2 system of equations. Particular solutions are obtained, as integrals of waves from point sources distributed inside the scattering medi

Joint inflammation in rabbits induced by preformed immune complexes

The rabbit knee joint was used to evaluate the inflammatory properties of immune complexes with different contents of antigen. Immune complexes made in vitro with antiserum from hyperimmunized rabbits and bovine serum albumin as antigen were injected into the joints. The reactivity of the individual animal was established by injection of normal rabbit serum into the contralateral joint. The number

Fast Spectral Velocity Estimation Using Adaptive Techniques: In-vivo Results

Adaptive spectral estimation techniques are known to provide good spectral resolution and contrast even when the observation window (OW) is very short. In this paper two adaptive techniques are tested and compared to the averaged periodogram (Welch) for blood velocity estimation. The blood power spectral capon (BPC) method is based on a standard minimum variance technique adapted to account for bo

Abstract in French Cet article a deux objectif. À un premier niveau, nous présentons un survol de quatre aspects du DP français et leur acquisition par des apprenants adultes suédophones, à savoir l’existence d’un stade de noms dits « nus », le statut syntaxique de l’article défini, le placement de l’adjectif et l’accord en genre. À un deuxième niveau, nous souhaitons illustrer une méthode de travThis article has two objectives. At a first level we present an overview of four aspects of the French DP and its acquisition by adult Swedish speaking learners, namely the existence of a bare noun stage, the syntactic status of the definite article, the placement of the adjective and gender agreement. At a second level, we wish to illustrate a method in Research on Language Acquisition which is i

Effects of high protein intakes

Among other nutrients of breast milk, the amino acid pattern is considered normative throughout infancy. Exclusive breastfeeding by a healthy mother should be the standard from birth to 6 months. During the breastfeeding period the protein intake is low in the human being compared too many other animals. The protein content in breast milk is about 1 g/1 00 ml and the daily protein intake approxima

Plasticity of TRPC expression in arterial smooth muscle: correlation with store-operated Ca2+ entry.

Loss of the smooth muscle contractile phenotype is critical in atherosclerosis and in restenosis after angioplasty, but its early signals are incompletely understood. In this study, we have explored the role of transient receptor potential canonical (TRPC) proteins, which have been suggested to mediate store-operated Ca2+ entry (SOCE). Contractility of rat cerebral arteries in organ culture is pre

SEQUENCE AND DISPERSION OF VENTRICULAR REPOLARIZATION ON THE ENDOCARDIUM AND EPICARDIUM Studies using the monophasic action potential mapping technique in humans and pigs

Materials and Methods: Monophasic action potential (MAP) were recorded, using the CARTO mapping system and NaviStar catheters, during sinus rhythm from the endocardium at 43 ± 15 LV or RV sites in 8 patients, at 61 ± 18 LV and/or RV sites in 10 pigs and during atrial pacing from the endo- and epicardium at 211 ± 54 LV and RV sites in additional 10 pigs. Local activation time (AT), MAP duration (MA

Search for supersymmetric particles in light gravitino scenarios and sleptons NLSP

A search for sleptons, neutralinos, charginos, sgoldstinos and heavy stable charged sleptons in the context of scenarios where the lightest supersymmetric particle is the gravitino, is presented. Data collected during 2000 with the DELPHI detector at centre-of-mass energies from 204 to 208 GeV were analysed and combined with all the data collected from 1995 to 1999 at lower energies. No evidence f

Titration of fatty acids in sugar-derived (APG) surfactants: A C-13 NMR study of the effect of headgroup size, chain length, and concentration on fatty acid pKa at a nonionic micellar interface

The pK(a) of a C-13-enriched fatty acid probe, tetradecanoic acid, was investigated in a variety of sugar-derived (APG) surfactants by using C-13 NMR to monitor the chemical environment of the probe during titration with base. There was an increase of approximately 2 pK(a) units for the probe within the micellar systems compared to the value of acetic acid in water. Analysis shows that the interfa
