In answer to recent experimental force measurements between oppositely charged surfaces we here reproduce the repulsion in the presence of multivalent salt using Monte Carlo simulations within the primitive model. Our osmotic pressure curves are in good agreement with experimental results. In contrast with Poisson-Boltzmann calculations, both repulsion and charge inversion are seen in the simulati
OBJECTIVES: To determine the biologic half-life of the S100B protein and to investigate if the elimination of S100B depends on glomerular filtration rate (GFR). DESIGN: Prospective human study. SETTING: University hospital. PARTICIPANTS: Sixteen patients who underwent cardiac surgery with cardiopulmonary bypass. INTERVENTIONS: Shed mediastinal blood (autotransfusion) was returned to the patients p
Background Patient-clinician communication is central to mental healthcare but neglected in research. Aims To testa new computer-mediated intervention structuring patient-clinician dialogue (DIALOG) focusing on patients' quality of life and needs for care. Method In a cluster randomised controlled trial, 134 key workers in six countries were allocated to DIALOG or treatment as usual; 507 people wi
Background: There has been a controversy regarding the cause of brachioradial pruritus: is it caused by a nerve compression in the cervical spine or is it caused by a prolonged exposure to sunlight? Objective: The purpose was to study clinical features of patients with brachioradial pruritus and to compare the cutaneous innervation in punch biopsies from the itchy skin of patients with the age-mat
The authors describe a 9-year-old boy who had an accident with his bicycle. He presented with hematuria a few weeks later, and cystoscopy results showed a polypod lesion near the veru montanum. The lesion was resected, and histologic examination showed a nephrogenic adenoma (NA), which recurred 6 years later with hematuria. NA is a rare lesion in a child's urethra and can be a source of hematuria.
Tamoxifen (Tam) is widely used in chemotherapy of estrogen receptor-positive breast cancer. It inhibits proliferation and induces apoptosis of breast cancer cells by estrogen receptor-dependent modulation of gene expression, but recent reports have shown that Tam (especially at pharmacological concentrations) has also rapid nongenomic effects. Here we studied the mechanisms by which Tam exerts rap
The azlB locus of Bacillus subtilis was defined previously by a mutation conferring resistance to a leucine analog, 4-azaleucine (J. B. Ward, Jr., and S. A. Zahler, J. Bacteriol. 116:727-735, 1973). In this report, azlB is shown to be the first gene of an operon apparently involved in branched-chain amino acid transport. The product of the azlB gene is an Lrp-like protein that negatively regulates
Background: Atopic dermatitis (AD) is common in the population, and studies have shown that the disease is on the increase. Studies based on hospital records reflect selected populations and may miss less severe cases of AD, and the use of self-reported questionnaires has the drawback of recall bias. Objectives: To investigate some possible factors influencing recall bias when questionnaires are u
Total and regional cerebral glucose metabolism (CMRgl) was measured by positron emission tomography with 2-(F-18) fluoro-2-deoxy-D-glucose ((18)FDG) in 20 term infants with hypoxic ischemic encephalopathy (HIE) after perinatal asphyxia. All infants had signs of perinatal distress, and 15 were severely acidotic at birth. Six infants developed mild HIE, twelve moderate HIE, and two severe HIE during
Smoluchowski's coagulation equation is studied for the kernel K (u, v) = E(u(alpha)v(beta) + u(beta) v(alpha)) with real, non-negative alpha, beta and E, using gamma distributions with a singularity at zero volume as initial size spectra. As the distribution parameter of the gamma distribution, p, approaches its lower limit (p -> 0) the distribution becomes similar to pv(p-1) 1 for small v. Asympt
The tense relationship between 'troublesome youth' and conventional society does not end with incarceration or institutional treatment. Rather, it is transformed into an abundance of interpersonal conflicts within incarceration and treatment. This article uses an interactionist perspective to critically assess five research approaches that account for these phenomena in various ways: 1) quarrels a
We introduce photons in partially quenched chiral perturbation theory and calculate the resulting electromagnetic loop-corrections at next-to-leading-order (NLO) for the charged meson masses and decay constants. We also present a numerical analysis to indicate the size of the different corrections. We show that several phenomenologically relevant quantities can be calculated consistently with phot
The organization of climbing fibre input to the cerebellar anterior lobe of the ferret was investigated in barbiturate-anaesthetized animals. Climbing fibre field potentials evoked on electrical stimulation of forelimb and hindlimb nerves were recorded at the cerebellar surface. Based on characteristic latencies of climbing fibre responses and their relative localization along the longitudinal axi
This manuscript investigates possible bifurcations into stationary wave-type solutions in situations where an isotropic elastic bulk is bonded by a non-coherent orthotropic interface to a rigid substrate. The interface is characterised by a tractionseparation-law capturing elastic and inelastic material behaviour. Based on an ansatz for stationary waves at the surface of the bulk being connected t
Congenic BioBreeding (BB) rats, homozygous for the autosomal lymphopenia (Lyp) gene (Lyp/Lyp), heterozygous (Lyp/+), or wild-type (+/+), were immunized with the T cell-dependent bacteriophage PhiX174 to determine effects of Lyp on primary and secondary antibody responses. The primary PhiX174 antibody response did not differ between the three different genotypes. In contrast, the secondary immune r
The endogenous C18 N-acylethanolamines (NAEs) N-linolenoylethanolamine (18:3 NAE), N-linoleoylethanolamine (18:2 NAE), N-oleoylethanolamine (18:1 NAE), and N-stearoylethanolamine (18:0 NAE) are structurally related to the endocannabinoid anandamide (20:4 NAE), but these lipids are poor ligands at cannabinoid CB1 receptors. Anandamide is also an activator of the transient receptor potential (TRP) v
The retinoblastoma gene product (pRb) is the main substrate for cyclin-dependent kinases (CDKs) during the G1/S transition. Aberrations in cell cycle regulatory proteins, which have been observed in many malignancies, can theoretically cause increased phosphorylation of pRb due to unbalanced CDK activities. The expression and phosphorylation of pRb and potential associations to cell cycle aberrati
An aircraft-based, multi-channel aerosol sampler for studies of the upper troposphere and lowermost stratosphere from the CARIBIC ( Civil Aircraft for Regular Investigation of the Atmosphere Based on an Instrument Container) platform was designed and calibrated. The sampler operates with an impaction technique at a flow rate of 10.4 lpm and consists of sixteen sampling channels. Samples are collec
Objective: To evaluate the eYcacy of the essential omega-6 fatty acid Gammalinolenic acid (GLA) on fatigue associated with primary Sjo¨ gren’s syndrome. Methods: Ninety patients with primary Sjo¨ gren’s syndrome (with or without signs of autoimmunity) entered a 6-month double blind placebo-controlled randomised trial with high dose GLA (extracted from Evening Primrose Oil ) or corn oil. The primar
More than 11 million children under 15 years in sub-Saharan Africa have lost at least one parent to AIDS. In Uganda, about 2 million children are orphans, with one or both parents dead. The objective of this study was to investigate the psychosocial consequences of AIDS orphanhood in a rural district in Uganda and to identify potential areas for future interventions. The study was conducted in a r
