Oil/water droplet formation by temperature change in the water/C16E6/mineral oil system

Droplet sizes of oil/water (O/W) nanoemulsions prepared by the phase inversion temperature (PIT) method, in the water/C16E6/mineral oil system, have been compared with those given by a theoretical droplet model, which predicts a minimum droplet size. The results show that, when the phase inversion was started from either a single-phase microemulsion (D) or a two-phase W+D equilibrium, the resultin

The clinical, metabolic and endocrine features and the quality of life in adults with childhood-onset craniopharyngioma compared with adult-onset craniopharyngioma

Background: Craniopharyngioma is a parasellar tumour that, although benign, tends to behave aggressively. It can occur at any age but most commonly presents in childhood or adolescence. Objectives: to investigate the frequency and severity of problems associated with craniopharyngioma, using the large international database (KIMS) for adult patients with GH deficiency (GHD), and to assess the diff

Exhaled and nasal NO levels in allergic rhinitis: relation to sensitization, pollen season and bronchial hyperresponsiveness

Exhaled nitric oxide is a potential marker of lower airway inflammation. Allergic rhinitis is associated with asthma and bronchial hyperresponsiveness. To determine whether or not nasal and exhaled NO concentrations are increased in allergic rhinitis and to assess the relation between hyperresponsiveness and exhaled NO, 46 rhinitic and 12 control subjects, all nonasthmatic nonsmokers without upper

Relational problems and psychiatric symptoms in couple therapy

Lundblad A-M, Hansson K. Relational problems and psychiatric symptoms in couple therapyInt J Soc Welfare 2005: 14: 256 -264 c Blackwell Publishing, 2005.This article describes couples attending family counselling in Sweden. The study group is compared with clinical groups and non-clinical groups. Self-rating instruments were com-pleted by 317 women and 312 men to evaluate the following: marital sa

Psychometric evaluation of multidimensional pain inventory (Swedish version) in a sample of elderly people.

Objectives The aim was to psychometrically evaluate the Swedish version of the Multidimensional Pain Inventory (MPI-S) and the “brief screening version of MPI-S” for use in an elderly sample. Methods This study comprised 175 people aged 76–99 years reporting pain and in need of help to manage daily living. The instrument’s factor structures were investigated through factor analyses, convergent

"Protein-like" copolymers: Effect of polymer architecture on the performance in bioseparation process

Recently, a new class of copolymers, so-called protein-like copolymers has been predicted theoretically by computer simulation. In these copolymers. the conformation of the copolymer determines the exposure of certain comonomer units to the outer solution. Depending on the conformation, copolymer molecules with essentially the same comonomer composition could have pronouncedly different properties

Morphology and structure of CuOx/CeO2 nanocomposite catalysts produced by inert gas condensation: An HREM, EFTEM, XPS, and high-energy diffraction study

Inert gas condensation (IGC) has been employed to produce nanoparticles of the low-temperature combustion catalyst CuOx/CeO2. For the first time we have used a multiple heating crucible setup to tailor various morphologies over the whole compositional range (2-98% Cu). The factors that control the growth, structure, and morphology of the nanocomposite have been studied. A powerful combination of c

Low-light-induced formation of semicrystalline photosystem II arrays in higher plant chloroplast

Remodeling of photosynthetic machinery induced by growing spinach plants under low light intensities reveals an up-regulation of light-harvesting complexes and down-regulation of photosystem II and cytochrome b(6)f complexes in intact thylakoids and isolated grana membranes. The antenna size of PSII increased by 40-60% as estimated by fluorescence induction and LHCII/PSII stoichiometry. These low-

Oral function test for monitoring suction and swallowing in the neurologic patient

Disturbances in swallowing are common in neurologic disease but difficult to evaluate in the clinical setting. Fundamental variables such as bolus volume, swallow capacity (volume ingested over time), and the relation between ingestion and time for important events in oral and pharyngeal swallowing have not been sufficiently studied. We therefore employed a composite method for monitoring oral and

Health profile of middle-aged women: The Women's Health in the Lund Area (WHILA) study.

BACKGROUND: Middle-aged women experience various health-related problems. The aim of this study was to evaluate the impacts of menopause status and hormone intervention on women's health. METHODS: In an ongoing, population-based study, 4943 women, born 1935 to 1945 and living in the Lund area of Southern Sweden, were included in this analysis. They completed a generic questionnaire pertaining to s

I-129 in Swedish rivers: distribution and sources

We analyzed the concentration of I-129 in the water of 26 rivers covering most of the runoff from Sweden, with the aim of assessing current contamination levels, distribution patterns and potential sources in freshwater systems of northern Europe. The results show relatively high values (up to 1.4 x 10(9) atoms 1(-1)), steeply decreasing levels with increasing latitude and a positive correlation w

Horizontal flight of a swallow (Hirundo rustica) observed in a wind tunnel, with a new method for directly measuring mechanical power

A swallow flying in the Lund wind tunnel was observed from the side and from behind, by two synchronised highspeed video cameras. The side-view camera provided a record of the vertical position of a white mark, applied to the feathers behind and below the eye, from which the vertical acceleration was obtained. The rear-view camera provided measurements of the mean angle of the left and right humer

Pain management in elderly persons who require assistance with activities of daily living: a comparison of those living at home with those in special accommodations.

Objectives: To describe and compare the methods of pain management used by elderly individuals with chronic pain and requiring assistance with activities of daily living, depending on whether they live alone, with someone, at home or in special accommodations. Methods: This study comprised 294 people aged 76–100 years, identified as having chronic pain and requiring assistance with activities of

Standard addition - A way of improving quantification of banned azo dyes in leather

An analytical procedure based on supercritical-fluid extraction and microwave-assisted extraction was applied on six different real leather samples for the determination of banned azo dyes. Determination of the dyes was performed indirectly by measuring their corresponding harmful aromatic amines, formed after reduction. A comparative study between external standard calibration and standard additi

Leukotriene D(4) affects localisation of vinculin in intestinal epithelial cells via distinct tyrosine kinase and protein kinase C controlled events

Local inflammatory reactions affect the integrity of intestinal epithelial cells, such as E-cadherin-mediated cell-cell interactions. To elucidate this event, we investigated the effects of an inflammatory mediator, leukotriene D(4 )(LTD(4)), on the phosphorylation status and properties of vinculin, a multi-binding protein known to interact with both the E-cadherin-catenin complex and the cytoskel
