The current work is devoted entirely to the study of passive transport phenomena, or more specifically, the more simple diffusion, electric migration and filtration of solute matter and water over glomerular and peritoneal capillary walls. The driving forces behind such trans-capillary transport phenomena have long been assumed to be simple gradients of concentration, hydrostatic pressure and elec
BACKGROUND: Transforming growth factor-β1 (TGF-β1) is a potent regulator of cell growth and differentiation. TGF-β1 has been shown to be a key player in tissue remodeling processes in a number of disease states by inducing expression of extracellular matrix proteins. In this study a quantitative proteomic analysis was undertaken to investigate if TGF-β1 contributes to tissue remodeling by mediatin
Over the past decade, liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) has evolved into the main proteome discovery technology. Up to several thousand proteins can now be reliably identified from a sample and the relative abundance of the identified proteins can be determined across samples. However, the remeasurement of substantially similar proteomes, for example those gene
Human blood plasma can be obtained relatively noninvasively and contains proteins from most, if not all, tissues of the body. Therefore, an extensive, quantitative catalog of plasma proteins is an important starting point for the discovery of disease biomarkers. In 2005, we showed that different proteomics measurements using different sample preparation and analysis techniques identify significant
Multidimensional LC-MS based shotgun proteomics experiments at the peptide level have traditionally been carried out by ion exchange in the first dimension and reversed-phase liquid chromatography in the second. Recently, it has been shown that isoelectric focusing (IEF) is an interesting alternative approach to ion exchange separation of peptides in the first dimension. Here we present an improve
Understanding how proteins and their complex interaction networks convert the genomic information into a dynamic living organism is a fundamental challenge in biological sciences. As an important step towards understanding the systems biology of a complex eukaryote, we cataloged 63% of the predicted Drosophila melanogaster proteome by detecting 9,124 proteins from 498,000 redundant and 72,281 dist
The expansion of pollinator-dependent crops, especially in the developing world, together with reports of worldwide pollinator declines, raises concern of possible yield gaps. Farmers directly reliant on pollination services for food supply often live in regions where our knowledge of pollination services is poor. In a manipulative experiment replicated at 23 sites across an Ethiopian agricultural
Background/aim: The role of the microbiome has been widely discussed in the etiology of appendicitis. The primary aim was to evaluate the microbiome in the normal appendix and in appendicitis specifically divided into the three clinically and histopathologically defined grades of inflammation. Secondary aims were to examine whether there were any microbiome differences between proximal and distal
A multiscale modeling framework, combining a graph-based vertex model of microstructure evolution with a GPU-parallelized crystal plasticity model, was recently proposed by the authors. Considering hot rolling of copper, the full capabilities of the model are demonstrated in the present work. The polycrystal plasticity model captures the plastic response and the texture evolution during materials
The biochemical methane potential (BMP) assays were used as a tool to investigate methane potential of chicken manure (CM) and three co-substrates (chicken processing waste, Miscanthus and seagrass) in mono-digestion and co-digestion studies for selecting regional biomass in a bid to support the expansion of a full-scale biogas plant. Two types of kinetic models (first order and modified Gompertz
Background: To establish integrated healthcare pathways for patients with neurodevelopmental disorders (ND) such as autism spectrum disorder and attention-deficit hyperactivity disorder is challenging. This study sets out to investigate the main concerns for healthcare professionals when integrating ND care pathways and how they resolve these concerns. Methods: Using classic grounded theory (Glase
The artistic doctoral project Singing in action – processes of vocal improvisation is an investigation of vocal improvised performance from my point of view as a classically trained singer and vocal improviser. It focuses on an artistic tradition which has its roots in medieval Provence and Italy (Wilén, 2013a) and which is an expanding classical vocal genre of today: opera and art song improvisat
Aims/hypothesis: Variations in FTO are the strongest common genetic determinants of adiposity, and may partly act by influencing dopaminergic signalling in the brain leading to altered reward processing that promotes increased food intake. Therefore, we investigated the impact of such an interaction on body composition, and peripheral and brain insulin sensitivity. Methods: Participants from the T
Mutation rates for X-linked recessive diseases have so far been estimated indirectly by postulating an equilibrium between the loss of defective genes caused by the low reproductive fitness of affected males and the gain resulting from new mutations. Here, for the first time, we directly estimate both the overall and sex-specific mutation rates for haemophilia B by detecting the gene defect of the
Is there a right to reject mental health care, or may such care be imposed against your will? Human rights law, developed prior to the Convention on the Rights of Persons with Disabilities (CRPD), answered this question with clear authorizations of compulsory interventions under certain circumstances: in essence, when the person has a psychosocial diagnosis, is perceived as in need of medical trea
OBJECTIVE: To assess whether quantitative capillary microscopy is a useful tool to evaluate capillary abnormalities in children with connective tissue diseases.METHODS: Eight children with juvenile dermatomyositis (JDM), 6 with mixed connective tissue disease (MCTD) and 23 healthy children were investigated with computer based quantitative capillary microscopy. Median disease duration was 1 year a
Handel och resande är en förutsättning för internationellt utbyte av såväl varor och människor som kultur och innovationer. Handeln och resandet går tillbaka till historiens gryning men har under de senaste århundradena blivit en allt viktigare del i den ekonomiska utvecklingen. Globaliseringen har till följd av tilltagande ekonomiskoch politisk integration drivit på utvecklingen av resandet och s
OBJECTIVES: To evaluate an objective and quantitative method for assessment of capillary abnormalities in systemic sclerosis (SSc).METHODS: Nailfold capillaries were investigated by capillary microscopy and photographed in 17 consecutive SSc patients (five with diffuse cutaneous systemic sclerosis (dSSc) and 12 with limited cutaneous systemic sclerosis (lSSc)) and in 17 healthy controls.

Lead(II) acetate [Pb(Ac)2, where Ac = acetate group (CH3-COO-)2] is a very common salt with many and varied uses throughout history. However, only lead(II) acetate trihydrate [Pb(Ac)2·3H2O] has been characterized to date. In this paper, two enantiotropic polymorphs of the anhydrous salt, a novel hydrate [lead(II) acetate hemihydrate: Pb(Ac)2·1/2H2O], and two decomposition products [corresponding t
