Diabetic children and their parents: personality correlates of metabolic control

Test measures of field-dependence-independence and impulsiveness-control were obtained from two groups of diabetic children and their parents, the children being in optimal (O, n = 12) or poor (P. n = 27) metabolic control and, according to the judgment of clinicians, showing optimal or poor psychological adaptation. Children of the O-group scored lower in impulsiveness and higher in realistic fun

Free cytosolic calcium during spontaneous contractions in smooth muscle of the guinea-pig mesotubarium

The free intracellular calcium ion concentration ([Ca2+]i) was measured simultaneously with isometric force in strips of guinea-pig mesotubarium using the Fura-2 technique. During the relaxed period (5-15 min) between spontaneous contractions [Ca2+]i continues to decrease after full mechanical relaxation to reach a minimal level of 86 +/- 8 nM (n = 9) just before the start of the next contraction.

Arrest of chlorophyll accumulation prior to anthocyanin formation in Euphorbia pulcherrima

Euphorbia pulcherrima Klotz plants exposed to short days (11 h light/13 h dark) for a period of eight weeks, developed flowers and a red canopy consisting of bracts and few true leaves. Plants maintained for three weeks under short day conditions, failed to produce flower primordia or a red canopy in the following 5 weeks in continuous light. Between the 4th and 5th short day week, the youngest le

Pollen analysis, chronology and palaeomagnetism of three Late Weichselian sites in southern Sweden

Popular Abstract in Swedish Pollenanalys, kronologi och paleomagnetism på tre senglaciala lokaler i södra Sverige Senglaciala sjösediment (d.v.s. avsatta under slutet av den senaste istiden) från tre bassänger i södra Sverige, Torreberga i Skåne, Farslycke i Blekinge och Bolmen i Småland, har studerats med avseende på pollensammansättning och paleomagnetism. Åldersbestämning och tidsjämförelser bThree sites, Torreberga in Skåne, Farslycke in Blekinge and Lake Bolmen in Småland, with Late Weichselian lake sediments were studied with respect to pollen analysis and palaeomagnetism. The chronologies are based on pollen stratigraphical correlations, radiocarbon dating and, for two of the sites, on a clay-varve chronology. The stratigraphies were correlated to the GRIP event stratigraphy and th

Pore structure in supermacroporous polyacrylamide based cryogels

Pore size and thickness of pore walls in macroporous polyacrylamide gels, so-called cryogels (pAAm-cryogels), were controlled by varying the content of monomers in the initial reaction mixture and the cross-linker used. The thickness of pore walls in pAAm-cryogels increased with increasing concentration of monomers in the initial reaction mixture. Pore volume in the supermacroporous pAAm-cryogels

The stable carbon isotope composition of the terrestrial biosphere: Modeling at scales from the leaf to the globe

Global data sets of the stable carbon isotope composition of plant leaves, of CO2 in canopy air, and of CO2 in the background atmosphere were compiled and compared to results of a global vegetation model (BIOME4) that simulated, at these three scales, the magnitude, direction, and timing of fluxes of CO2 and C-13 between the biosphere and the atmosphere. Carbon isotope data on leaves were classifi

Retinopathy and nephropathy in insulin-dependent diabetics: an inconsistent relationship?

The association between retinopathy and nephropathy was investigated in a retrospective study of 52 insulin-dependent diabetics with preproliferative or proliferative retinopathy and in 48 patients without or with background retinopathy. The duration of diabetes was 23.2 +/- 1.0 years (mean +/- SEM) and 22.0 +/- 1.2 years in the two groups. Patients in the retinopathy group showed a higher frequen

Gender Based Focal Points

The subjects behaved significantly more “hawkish” in an experimental battle of the sexes game when the co-player was a woman compared to when it was a man. Discrimination helped the parties to coordinate and increase the average earnings in the subject group of mixed sex, compared to the unisex groups.

The Rate of Isomerisation of Peptidyl-proline Bonds as a Probe for Interactions in the Physiological Denatured State of Chymotrypsin Inhibitor 2

There are four peptidyl-proline bonds in the 64-residue protein chymotrypsin inhibitor 2 (CI2), all of which are in the trans conformation in the native structure. The isomerisation of one or more of these peptidyl-proline bonds to the cis conformation in the denatured state gives rise to heterogeneity, leading to both fast and slow-folding species. The refolding of the fast-folding species, which

An assessment of governmental wind power programmes in Sweden-using a systems approach

The purpose of this paper is to assess the effects, the cost efficiency, and the goal achievement of policy instruments aimed for the development and deployment of wind power in Sweden during the period 1975 to 2000. The paper presents an empirical example of a socio-technical system-based approach for impact assessment, in which changes in the wind power system are described and analysed with res

Simulations of the absorption and fluorescence of indole in aqueous solution and at a nonpolar/polar interface

Theoretical results are presented on the absorption and fluorescence of indole in aqueous solution as well as at the air/water surface. We use a combined quantum chemical statistical mechanical model with explicit solvent. An approximate ab initio complete active space self-consistent field description of the indole molecule is used, coupled to a discrete polarizable water medium. From the bulk si

Complications of video-assisted gastrostomy in children with or without a ventriculoperitoneal shunt

The aim of the study was to test the hypothesis that the presence of a ventriculoperitoneal shunt ( VPS) influences the frequency of postoperative complications after video-assisted gastrostomy ( VAG) in children. When using a power of 80%, a critical value for significance of 5% and an assumed population-based standard deviation of 0.4, it will be required to have a sample size of at least 14 chi

Compact third-order multidimensional upwind scheme for Navier-Stokes simulations

A new compact third-order scheme for the solution of the unsteady Navier-Stokes equations on unstructured grids is proposed. The scheme is a cell-based algorithm, belonging to the class of Multidimensional Upwind schemes, which uses a finite-element reconstruction procedure over the cell to achieve third order (spatial) accuracy. Derivation of the scheme is given. The asymptotic accuracy, for stea

A simplified computational kernel for trellis-based decoding

A simplified branch metric and add-compare-select (ACS) unit is presented for use in trellis-based decoding architectures. The simplification is based on a complementary property of best feedforward and some systematic feedback encoders. As a result, one adder is saved in every other ACS unit. Furthermore, only half the branch metrics have to be calculated. It is shown that this simplification bec

Regimens of factor VIII administration--continuous infusion vs. bolus

The Malmo protocol for immune tolerance induction uses intermittent injections of factor VIII/IX together with intravenous IgG and cyclophosphamide. In order to increase the production of antigen-antibody complexes, and also to improve cost-efficacy, we applied continuous infusion instead of intermittent injection in 5 high-responders (3 hemophilia A and 2 hemophilia B). All treatment attempts fai

Genetic and genomic analysis of arthritis regulating regions in human and mouse

Identifying genes involved in the disease pathways of complex diseases such as Rheumatoid arthritis (RA) has been shown to be very difficult. Despite decades of research still only a handful of genes have been convincingly identified as risk genes. RA is a common autoimmune disorder that affects approximately 1% of the population and knowledge of the contributing genetic factors would greatly incr
