Morphological findings in placentae of insulin-dependent diabetic patients treated with continuous subcutaneous insulin infusion (CSII)

Twenty-one placentae from type I (insulin-dependent) pregnant diabetic patients, treated with continuous subcutaneous insulin infusion (CSII), were studied morphologically. Despite a near-optimal blood glucose control the placental changes were identical to those previously reported in diabetic pregnancy. The most frequently observed lesion was that of relative placental immaturity; this, when ext

First records of soilborne Phytophthora species in Swedish oak forests

Thirty-two oak stands in southern Sweden, 27 with predominantly declining trees and five with a higher proportion of healthy trees were investigated regarding the presence of soilborne Phytophthora species. Phytophthora quercina , an oak-specific fine root pathogen, was isolated from rhizosphere soil samples in 10 of the 27 declining stands. Additionally, P. cactorum and P. cambivora were recovere

Fast and Stable Polynomial Equation Solving and Its Application to Computer Vision

This paper presents several new results on techniques for solving systems of polynomial equations in computer vision. Gröbner basis techniques for equation solving have been applied successfully to several geometric computer vision problems. However, in many cases these methods are plagued by numerical problems. In this paper we derive a generalization of the Gröbner basis method for polynomial eq

Expression and mutation analysis of the discoidin domain receptors 1 and 2 in non-small cell lung carcinoma.

The discoidin domain receptors, (DDR) 1 and DDR2, have been linked to numerous human cancers. We sought to determine expression levels of DDRs in human lung cancer, investigate prognostic determinates, and determine the prevalence of recently reported mutations in these receptor tyrosine kinases. Tumour samples from 146 non-small cell lung carcinoma (NSCLC) patients were analysed for relative expr

Identification of T1D susceptibility genes within the MHC region by combining protein interaction networks and SNP genotyping data

To develop novel methods for identifying new genes that contribute to the risk of developing type 1 diabetes within the Major Histocompatibility Complex (MHC) region on chromosome 6, independently of the known linkage disequilibrium (LD) between human leucocyte antigen (HLA)-DRB1, -DQA1, -DQB1 genes. We have developed a novel method that combines single nucleotide polymorphism (SNP) genotyping dat

Repetitive usage testing with budesonide in experimental nickel--allergic contact dermatitis in individuals hypersensitive to budesonide

BACKGROUND: Contact allergy to topical corticosteroids on patch testing is well recognized, but the clinical significance is uncertain. OBJECTIVES: To determine the clinical relevance of contact allergy to topical corticosteroids. METHODS: Seven patients hypersensitive to both budesonide and nickel repeatedly applied budesonide, betamethasone valerate or the common base for both corticosteroids to

Iterative methods for cancellation of intercarrier interference in OFDM systems

We consider orthogonal frequency-division multiplexing systems with intercarrier interference (ICI) due to insufficient cyclic prefix and/or temporal variations. Intersymbol interference (ISI) and ICI lead to an error floor in conventional receivers. We suggest two techniques for the equalization of ICI. The first, called "operator-perturbation technique" is an iterative technique for the inversio

Contribution of mitral annular excursion and shape dynamics to total left ventricular volume change

The mitral annulus (MA) has a complex shape and motion, and its excursion has been correlated to left ventricular (LV) function. During the cardiac cycle the annulus' excursion encompasses a volume that is part of the total LV volume change during both filling and emptying. Our objective was to evaluate the contribution of MA excursion and shape variation to total LV volume change. Nine healthy su

Influence of childhood atopic dermatitis on future worklife

Objectives The purpose of this study was to perform a population-based follow-up of people with childhood atopic dermatitis with respect to the possible influence on their worklife. Methods Medical records of the school health care services in Stockholm, Sweden, were reviewed for people born between 1960 and 1969. Altogether 600 persons with signs of atopic dermatitis ('' cases '') and 600 matched

Action-based sensory encoding in spinal sensorimotor circuits

The concept of a modular organisation of the spinal withdrawal reflex circuits has proven to be fundamental for the understanding of how the spinal cord is organised and how the sensorimotor circuits translate sensory information into adequate movement corrections. Recent studies indicate that a task-related body representation is engraved at the network level through learning-dependent mechanisms

Simulation of the release from a multiparticulate system validated by single pellet and dose release experiments

A previously described single-pellet release model has been simplified and modified to give predictions of the release from multiple-pellet systems, besides describing the release from single pellets. The simplified single-pellet model has been verified using single-pellet data and has been used to estimate three release-controlling parameters, namely the pellet core radius, the overall mass trans

Influence of urban morphology and sea breeze on hot humid microclimate: the case of Colombo, Sri Lanka

Urbanisation leads to increased thermal stress in hot-humid climates due to increased surface and air temperatures and reduced wind speed. We examined the influence of urban morphology and sea breeze on the microclimate of Colombo, Sri Lanka. Air and surface temperatures, humidity and wind speed were measured at 1 rural and 5 urban sites during the warmest season. The urban sites differed in their

Platelet-derived growth factor promotes survival of rat and human mesencephalic dopaminergic neurons in culture

The effect of two isoforms of platelet-derived growth factor (PDGF), PDGF-AA and PDGF-BB, was tested on dissociated cell cultures of ventral mesencephalon from rat and human embryos. PDGF-BB but not PDGF-AA reduced the progressive loss of tyrosine hydroxylase- (TH)-positive neurons in rat and human cell cultures. The mean number of TH-positive cells in the PDGF-BB-treated rat culture was 64% and 1

Annual CO2 exchange between a nutrient-poor, minerotrophic, boreal mire and the atmosphere

[1] Mires are key landscape elements at high latitudes and have certainly accumulated carbon during the Holocene, but their current carbon balance at the present time is very unclear. The major carbon flux is the land-atmosphere CO2 exchange and full-year data are still limited. Here we present data from 3 a (2001-2003) of continuous Eddy Covariance measurements at Degero Stormyr (64 degrees 11'N,

Genetic Variation in Sex Hormone Genes Influences Heel Ultrasound Parameters in Middle-Aged and Elderly Men: Results From the European Male Aging Study (EMAS)

Genes involved in sex hormone pathways are candidates for influencing bone strength. Polymorphisms in these genes were tested for association with heel quantitative ultrasound (QUS) parameters in middle-aged and elderly European men. Men 40-79 yr of age were recruited from population registers in eight European centers for the European Male Aging Study (EMAS). Polymorphisms were genotyped in AR, E
