Central Role of Rho Kinase in Lipopolysaccharide-Induced Platelet Capture on Venous Endothelium.

BACKGROUND:: Platelet-endothelial cell interactions play a key role in hemostasis and pathological coagulation and are dependent on different surface molecules that are expressed upon activation (eg, mediated by lipopolysaccharide [LPS]). Recently, we have shown that Rho kinase plays a central role in LPS-mediated leukocyte-endothelial cell interactions. We investigated the role of Rho-kinase in i

Extracellular matrix alterations and acute inflammation; developing in parallel during early induction of pulmonary fibrosis.

Pulmonary fibrosis is a hallmark of several systemic diseases such as systemic sclerosis. Initiation and early development is not well characterized, as initiation usually is unnoticed in patients, yet fibrosis has been considered a late event, occurring after an inflammatory phase. By utilizing an animal model, the starting point can be defined and the initiation process and early development tho

Electron correlation: keeping close to an orbital description

This article deals with excited-state properties and spectroscopies which probe them. We argue that the orbitals obtained in local density theory form an excellent basis for discussing excited states and that the self-energy operator (or optical potential) associated with one-electron-type excited states is closely diagonal in such a basis. This diagonality often leads to considerable simplificati

Histidine-rich glycoprotein promotes bacterial entrapment in clots and decreases mortality in a mouse model of sepsis.

Streptococcus pyogenes is a significant bacterial pathogen in humans. In this study, Histidine-rich glycoprotein (HRG), an abundant plasma protein, was found to kill S. pyogenes. Furthermore, S. pyogenes grew more efficiently in HRG deficient plasma, and clots formed in this plasma were significantly less effective at bacterial entrapment and killing. HRG deficient mice were strikingly more suscep

p38 Mitogen-activated protein kinase signaling regulates streptococcal M1 protein-induced neutrophil activation and lung injury.

M1 serotype of Streptococcus pyogenes can cause STSS and acute lung damage. Herein, the purpose was to define the role of p38 MAPK signaling in M1 protein-induced pulmonary injury. Male C57BL/6 mice were treated with specific p38 MAPK inhibitors (SB 239063 and SKF 86002) prior to M1 protein challenge. Edema, neutrophil infiltration, and CXC chemokines were determined in the lung, 4 h after M1 prot

Geographical Location and Urbanization of the Swedish Manufacturing Industry, 1900-1960: Evidence from a New Database

This article introduces a new database, based on official statistics, of regional manufacturing industries in Sweden. We employ this database to examine the distribution of manufacturing activity across Swedish regions and cities, 1900–1960. Over this period we observe an increasing concentration of manufacturing activities, reaching a peak around 1940, across the northern, southern and western pa

Direct conversion of human fibroblasts to dopaminergic neurons.

Recent reports demonstrate that somatic mouse cells can be directly converted to other mature cell types by using combined expression of defined factors. Here we show that the same strategy can be applied to human embryonic and postnatal fibroblasts. By overexpression of the transcription factors Ascl1, Brn2, and Myt1l, human fibroblasts were efficiently converted to functional neurons. We also de

Increased levels of cell-free hemoglobin, oxidation markers, and the antioxidative heme scavenger alpha(1)-microglobulin in preeclampsia.

Preeclampsia is a major cause of morbidity and mortality during pregnancy. To date, the pathogenesis of the disease is not fully understood. Recent studies show that preeclampsia is associated with overexpression of the hemoglobin genes alpha2 and gamma and accumulation of the protein in the vascular lumen of the placenta. Hypothesizing that cell-free hemoglobin leaks from the placenta into the ma

Transient direct and inverse scattering for inhomogeneous viscoelastic media:Obliquely incident SH mode

A stratified viscoelastic medium in the time domain is characterised by two creep compliances that are functions of time and depth, and a density that is a function of depth. In this paper the direct scattering problem of a plane horizontal shear wave obliquely incident on a stratified viscoelastic medium is treated in detail. A general discussion of the corresponding inverse problem is given. A s

Purification of transforming growth factor-beta 1 binding proteins from porcine uterus membranes

We have identified several transforming growth factor-beta 1 (TGF-beta 1) binding proteins in solubilized and glycoprotein-enriched porcine uterus membrane fractions by affinity cross-linking and in-gel ligand binding using 125I-labeled TGF-beta 1. By a ligand affinity chromatography using a column of immobilized recombinant TGF-beta 1, four components of apparent molecular weights 160,000, 80,000

Characterisation of behavioural and neurodegenerative changes induced by intranigral 6-hydroxydopamine lesions in a mouse model of Parkinson's disease.

Abstract Despite the widespread use of mice as models of Parkinson's disease there is a surprising lack of validation and characterisation of unilateral lesion models in mice and the extent of behavioural impairments induced by such lesions. The aim of the present study was to characterise the behavioural deficits observed after injection of 6-hydroxydopamine unilaterally into the substantia nigra

Infrared spectroscopy reveals both qualitative and quantitative differences in equine subchondral bone during maturation

The collagen phase in bone is known to undergo major changes during growth and maturation. The objective of this study is to clarify whether Fourier transform infrared (FTIR) microspectroscopy, coupled with cluster analysis, can detect quantitative and qualitative changes in the collagen matrix of subchondral bone in horses during maturation and growth. Equine subchondral bone samples (n = 29) fro

Risk of haemorrhagic and ischaemic stroke in patients with cancer: A nationwide follow-up study from Sweden.

BACKGROUND: Stroke is common in cancer patients, but risk estimates for different cancer sites/types have not been determined. The aim of this nationwide study was to examine whether there is an association between cancer and first hospitalisation for haemorrhagic or ischaemic stroke. METHODS: All 820,491 individuals in Sweden with a diagnosis of cancer between 1st January 1987 and 31st December 2

The use of drama to support reflection and understanding of the residents' situation in dementia care: a pilot study.

Background: One key aspect of person-centredness is striving to understand both the patients' experiences and behaviours from their perspective. These aspects are precisely those that staff in dementia care highlight as causing them most difficulty because the people in their care have major problems expressing themselves. There is thus a need to develop a method to help the staff to achieve inter
