Age-related increase in wall stress of the human abdominal aorta: An in vivo study

Background: The regulation of wall stress in the abdominal aorta (AA) of humans might be of specific interest, because the AA is the most common site for aneurysm formation in which wall stress seems to be an important pathophysiological factor. We studied the age-related changes in wall stress of the AA in healthy subjects, with the common carotid artery (CCA) as a comparison. Methods. A total of

Cartilage oligomeric matrix protein and thrombospondin 1. Purification from articular cartilage, electron microscopic structure, and chondrocyte binding

Cartilage oligomeric matrix protein (COMP) and thrombospondin 1 (TSP1) were purified in a native form from normal bovine articular cartilage. The key step in the purification scheme was selective extraction with EDTA-containing buffer. Final separation of these two molecules was achieved by heparin affinity chromatography. Particles viewed by electron microscopy after rotary shadowing and negative

Rashba effect at magnetic metal surfaces

Exchange-split two-dimensional electronic states at the magnetic Gd(0001) surface change their energy dispersion upon magnetization reversal owing to the Rashba effect. The Rashba parameter is found to be substantially enhanced and to change sign when an epitaxial metal-oxide surface layer is formed. The experimental observations are quantitatively described by ab initio calculations giving a deta

Morbidity and mortality among foreign-born Swedes

Popular Abstract in Swedish Det svenska samhället har under senare delen av 1900-talet påverkats och förändrats på grund av en ökad internationell migration. År 1950 var 2,8 % av den svenska befolkningen utrikesfödd; idag utgör de utrikesfödda 12,0 % av totalbefolkningen. Om även andragenerationens migranter (de som har en eller båda föräldrar utrikesfödda) räknas med utgör första och andrageneratAims: The general aim of this thesis was to describe and compare the group of foreign-born persons living in Sweden and native Swedes with regard to health development over time, thus studying the influence of migration on health. Methods: All four studies are based on data from Statistics Sweden (SCB) and the National Board of Health and Welfare, Centre for Epidemiology covering the period 1970?

Refugee Immigrants in Sweden - educational investments and labour market integration

This thesis analyses educational investments and labour market attachment for refugee immigrants who received a permanent visa to Sweden during 1987-1991. It consists of five self-contained chapters. Chapter 2 presents a brief overview of the historical process behind immigration to Sweden from the post-war period until today, give an orientation on the development of Swedish immigration policy du

CYP17 genetic variation and risk of breast and prostate cancer from the national Cancer Institute Breast and Prostate Cancer Cohort Consortium (BPC3)

CYP17 encodes cytochrome p450c17 alpha, which mediates activities essential for the production of sex steroids. Common germ line variation in the CYP17 gene has been related to inconsistent results in breast and prostate cancer, with most studies focusing on the nonsynonymous single nucleotide polymorphism (SNP) T27C (rs743572). We comprehensively characterized variation in CYP17 by direct sequenc

Historical diversification of migration patterns in a passerine bird

Migratory strategies of birds require complex orientation mechanisms, morphological adaptations, and life-history adjustments. From an evolutionary perspective, it is important to know how fast this complex combination of traits can evolve. We analyzed mitochondrial control-region DNA sequences in 241 blackcaps (Sylvia atricapilla) from 12 populations with different migratory behaviors. The sample

Substance P relaxes rat bronchial smooth muscle via epithelial prostanoid synthesis

BACKGROUND: Substance P is present in bronchial nerve fibres. The physiological actions of substance P are mediated via tachykinin NK(1) receptors. Immunochemical studies have demonstrated tachykinin NK(1) receptors in the rat airway epithelium. OBJECTIVE: To elucidate how epithelial tachykinin NK(1) receptors affect smooth muscle response to substance P. METHODS: Contractile response of isolated

Graded quasi-Lie algebras

This paper is concerned with a new class of graded algebras naturally uniting within a single framework various deformations of the Witt, Virasoro and other Lie algebras based on twisted and deformed derivations, as well as color Lie algebras and Lie superalgebras.

Ultrastructural immunolocalization of cartilage oligomeric matrix protein (COMP) in relation to collagen fibrils in the equine tendon

The structure and organisation of the extracellular matrix, and in particular the axial alignment of type I collagen fibrils, are essential for the tensile strength of tendons. The resident tenocytes synthesize and maintain the composition of the extracellular matrix, which changes with age and maturation. Other components of the extracellular matrix include less abundant collagen types II, III, V

Routine assessment of performance status during palliative chemotherapy when approaching end-of-life.

Palliative chemotherapy treatment (PCT) offered late in the cancer disease trajectory may be problematic. It is not easy to accurately calculate whether the potential benefits will outweigh the side-effects. This study investigates whether routine use of the Performance Status in Palliative Chemotherapy questionnaire (PSPC) affects the proportions of patients receiving PCT during the last month of

Androgen Receptor Genotype in Humans and Susceptibility to Endocrine Disruptors.

Although animal studies have raised concern that the influence of endocrine-disrupting compounds would obstruct the development of the male reproductive system, in general, exposure levels far above those found in humans have been needed to induce reproductive toxicity in animal models. Human data are inconclusive and have evoked the question whether endocrine-disrupting compounds can have any imp

Dissecting the potential molecular mechanisms underlying alpha-synuclein cell-to-cell transfer in Parkinson's disease.

Alpha-synuclein (alpha-syn) aggregation is central to neuropathological changes in Parkinson's disease. The aggregates spread within the central nervous system according to a very predictable pattern. A prion-like transmission of alpha-syn aggregates has been recently proposed to explain this propagation pattern. First, we review the growing evidence for such a mechanism. This process is likely to

DAPP1 undergoes a PI 3-kinase-dependent cycle of plasma-membrane recruitment and endocytosis upon cell stimulation

BACKGROUND: Phosphoinositide (PI) 3-kinase and its second messenger products, phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P(3)) and phosphatidylinositol 3,4-bisphosphate (PtdIns(3,4)P(2)), play important roles in signalling processes crucial for cell movement, differentiation and survival. Previously, we isolated a 32kDa PtdIns(3,4,5)P(3)-binding protein from porcine leukocytes. This pr

Glucosylated cholesterol in mammalian cells and tissues: formation and degradation by multiple cellular β-glucosidases.

The membrane lipid glucosylceramide (GlcCer) is continuously formed and degraded. Cells express two GlcCer-degrading β-glucosidases, GBA and GBA2, located in and outside the lysosome, respectively. Here we demonstrate that through transglucosylation both GBA and GBA2 are able to catalyze in vitro the transfer of glucosyl-moieties from GlcCer to cholesterol, and vice versa. Furthermore, the natural

OBJECTIVE: To evaluate feasibility and morbidity of robot assisted laparoscopic radical hysterectomy. METHODS: From December 2005 to September 2008 robot assisted laparoscopic radical hysterectomy and pelvic lymphadenectomy was performed on 80 women. Using a prospective protocol, and an active investigation policy for defined adverse events, perioperative, short and long term data were obtained. R

Incidence and mortality in epithelial ovarian cancer by family history of any cancer.

BACKGROUND: Practically all data on familial risk in ovarian and other cancers are based on incident cancer, whereas familiality in cancer mortality is largely unknown. If fatal forms of cancer are a highly familial subtype, then familial risk for mortality may exceed that of incidence, which is relevant for clinical decision making and counseling. METHODS: Ovarian cancer patients in the nationwid

Reversible cerebral vasoconstriction syndrome associated with autonomic dysreflexia.

A 32-year-old man with a residual spastic quadriparesis from a traumatic C5-C6 fracture experienced a severe thunderclap headache. The medical history revealed an episode of autonomic dysreflexia (AD) due to neurogenic bladder/urinary tract infection (UTI). Blood pressure monitoring at admission revealed hypertension; blood pressure reaching 160/100 mmHg (average blood pressure in these patients a
