A set of simple analytical equations, derived from the Flory-Huggins theory, are used to identify the dominant driving forces for phase separation and solute (e.g., protein) partitioning, in the absence and presence of added electrolyte, in every general class of aqueous two-phase systems. The resulting model appears to capture the basic nature of two-phase systems and all trends observed experime

Expression of pituitary adenylate cyclase-activating polypeptide in sensory neurons varies with injury or inflammation. The neurotrophins NGF and NT-3 are profound regulators of neuronal peptidergic phenotype in intact and injured sensory neurons. This study examined their potential for modulation of PACAP expression in adult rat with intact and injured L4-L6 spinal nerves with or without immediat

This article deals with the legal understanding of the demands in working life on employees’ability to cooperate. The concept of cooperation ability is here used in the sense of an ability to actively facilitate communication and foster relationships with colleagues and supervisors through flexibility and commitment, and thereby benefit the employer’s business. Special attention is paid to the dis

It is now increasingly recognized that aviation is an important driver of individual and global mobility. Growth in mobility is not evenly distributed, however: recent studies indicate that a relatively small, highly mobile part of society may account for a large share of the total distances travelled. In reviewing one of the processes that may lead to growth in individual aeromobility, the paper

Affinity chromatography is routinely used mostly on a preparative scale to isolate different biomolecules such as proteins and carbohydrates. To this end a variety of proteins is in common use as ligands. To extend the arsenal of binders intended for separation of carbohydrates, we have explored the use of carbohydratebinding modules (CBM) in affinity chromatography. The thermostable protein CBM4-

This study is a long-term follow-up in narrative form of three former psychiatric patients who had been discharged eight to nine years earlier from an outpatient occupational therapy programme. The purpose of the study was to gain an understanding about the participants' views about the period of therapy from a long-term perspective and of how the outcome of therapy could be understood within the

Density functional calculations have been used to investigate oxygen atom transfer reactions from the biological oxygen atom donors trimethylamine N-oxide (Me3NO) and dimethyl sulfoxide (DMSO) to the molybdenum(IV) complexes [MoO(mnt)(2)](2-) and [Mo(OCH3)(mnt)(2)](-) (mnt = maleonitrile-1,2-dithiolate), which may serve as models for mononuclear molybdenum enzymes of the DMSO reductase family. The

Background: A major part of medical pathology in internal medicine is associated with chronic alcoholism. The aim of the current study was to investigate whether screening for Alcohol Use Disorders (AUD) can be improved through determination of direct ethanol metabolites compared to traditional biological state markers, the Alcohol Use Disorders Identification Test (AUDIT) and additional self-repo

BACKGROUND. The objective of the current study was to compile prospective, population-based data on cutaneous invasive melanomas in Sweden during the period from 1990 to 1999, to describe and analyze survival data and prognostic factors, and to make comparisons with previously published Swedish and international data. METHODS. Twelve thousand five hundred thirty-three patients, which included 97%

Pubertal growth was studied in 10 girls previously treated for acute lymphoblastic leukemia. The average age at menarche was 12.2 years, which is significantly lower (p less than 0.01) than the expected 13.1 years. Compared with normal girls, these girls showed a subnormal (p less than 0.05) peak height velocity during the second year before menarche. The remaining growth before menarche as well a

To obtain a deeper insight into the genes and gene networks involved in the development of placentopathies, we have assessed global gene expression in three different models of placental hyperplasia caused by interspecies hybridization (IHPD), cloning by nuclear transfer, and mutation of the Esx1 gene, respectively. Comparison of gene expression profiles of approximately 13,000 expressed sequence

MAX-lab has introduced a local perturbation to the electron orbit of the MAX II storage ring, providing users at the SX700 monochromator beam line, D1011, with elliptically polarised soft X-rays. This is achieved by using corrector magnets to send the electron orbit on an ascending or descending trajectory through the dipole magnet source. This simple "bump" approach has many advantages over and a

DNA interacts with insoluble monolayers made of cationic amphiphiles as well as with monolayers of zwitterionic lipids in the presence of divalent ions. Binding to dioctadecyldimethylammonium bromide (DODAB) or distearoyl-sn-glycero-3-phosphocholine (DSPC) monolayers in the presence of calcium is accompanied by monolayer expansion. For the positively charged DODAB monolayer, this causes a decrease

Synaptogenesis, the formation of functional synapses, is a crucial step for the development of the central nervous system. Among the genes involved in this process are cell adhesion molecules, such as protocadherins and neuroligins, which are essential factors for the identification of the appropriate partner cell and the formation of synapses. In this work, we studied the expression and the genet

A major bottleneck in understanding zoonotic pathogens has been the analysis of pathogen co-infection dynamics. We have addressed this challenge using a novel direct sequencing approach for pathogen quantification in mixed infections. The major zoonotic food-borne pathogen Campylobacter jejuni, with an important reservoir in the gastrointestinal (GI) tract of chickens, was used as a model. We inve

Excessive secretion of glucagon is a major contributor to the development of diabetic hyperglycemia. Secretion of glucagon is regulated by various nutrients, with glucose being a primary determinant of the rate of alpha cell glucagon secretion. The intra-islet action of insulin is essential to exert the effect of glucose on the alpha cells since, in the absence of insulin, glucose is not able to s

Patients with severely deforming rheumatoid arthritis and impaired function of the upper extremity are often unable to use conventional walking aids. This report describes 42 such patients who were equipped with altogether 75 individually manufactured, lightweight walking aids (12 crutches, 12 forearm-crutches, 39 crutch-sticks and 12 sticks). A plaster cast of the patient's grip as well as analys

The workshop was organised to discuss the validity and limitations of existing functional markers of Se status in human subjects and to identify future research priorities in this area. Studies presented as part of this workshop investigated: the bioavailability of Se from different dietary sources; potential functional markers of Se status; individual variation in response to Se; the effect of ma
