Incidence of Stroke and Stroke Subtypes in Malmo, Sweden, 1990-2000. Marked Differences Between Groups Defined by Birth Country.

Background and Purpose-The proportion of immigrants has increased in Sweden markedly during the last decades, as in many other Western countries. Incidence of stroke has increased during this period. However, it is primarily unknown whether incidence of stroke and stroke subtypes in Sweden is related to country of birth. Methods-Incidence of first-ever stroke was followed during 10 years in a coho

Amino acid substitutions in the N-terminal segment of cystatin C create selective inhibitors of lysosomal cysteine proteinases

We used site-directed mutagenesis to alter the specificity of human cystatin C, an inhibitor with a broad reactivity against cysteine proteinases. Nine cystatin C variants containing amino acid substitutions in the N-terminal (L9W, V10W, V10F and V10R) and/or the C-terminal (W106G) enzyme-binding regions were designed and produced in Escherichia coli. It was discovered that the inhibition profile

The utility of the GHRH-arginine test for diagnosing GH deficiency in adults with childhood acute lymphoblastic leukemia (ALL) treated with cranial irradiation.

Context: The insulin tolerance test ( ITT) is the current standard diagnostic test for the diagnosis of adult GH deficiency ( GHD), but alternative tests, such as the GHRH- arginine test, have been proposed. Objective: We investigated the sensitivity and specificity of the GHRH- arginine test using ITT as the gold standard in diagnosing GHD in a group of young adults treated with cranial irradiati

Phenotypic expression of autosomal dominant retinitis pigmentosa in a Swedish family expressing a Phe-211-Leu variant of peripherin/RDS

PURPOSE: To characterize the clinical phenotype, with emphasis on electrophysiology, of members of a Swedish family with autosomal dominant retinitis pigmentosa due to a novel mutation, F211L, in the peripherin/RDS gene. METHODS: Nine patients with autosomal dominant retinitis pigmentosa and two healthy family members underwent a full clinical evaluation including kinetic visual field testing, mea

Fusion, disruption, and expression of HMGA2 in bone and soft tissue chondromas

Soft tissue and skeletal chondromas are rare entities, and only 21 cases with abnormal karyotypes have been reported. A survey of these, and 10 new cases reported herein, showed that the 12q13-15 segment is nonrandomly involved in structural rearrangements in chondromas. The HMGA2 (HMGI-C) locus in 12q15 is frequently rearranged in other benign mesenchymal tumors, and this study aimed at character

Extraterrestrial chromite in Middle Ordovician marine limestone at Kinnekulle, southern Sweden - Traces of a major asteroid breakup event

The distribution of sediment-dispersed extraterrestrial chromite grains and other Cr-rich spinels (> 63 mu m) has been studied in Middle Ordovician Orthoceratite Limestone from two quarries at Kinnekulle, southern Sweden. In the Thorsberg quarry, all similar to 3.2 m thick sequence of beds previously shown to be rich in fossil meteorites is also rich in sediment-dispersed extraterrestrial chromite

Development and characterisation of a novel rat model of Parkinson's disease induced by sequential intranigral administration of AAV-α-synuclein and the pesticide, rotenone.

Modeling Parkinson's disease remains a major challenge for preclinical researchers, as existing models fail to reliably recapitulate all of the classic features of the disease, namely, the progressive emergence of a bradykinetic motor syndrome with underlying nigrostriatal alpha-synuclein protein accumulation and nigrostriatal neurodegeneration. One limitation of the existing models is that they a

Multiproxy analysis of a new terrestrial and a marine Cretaceous-Paleogene (K-Pg) boundary site from New Zealand

An integrated study of palynology, Mossbauer spectroscopy, mineralogy and osmium isotopes has led to the detection of the first K-Pg boundary clay layer in a Southern Hemisphere terrestrial setting. The K-Pg boundary layer was independently identified at centimetre resolution by all the above mentioned methods at the marine K-Pg boundary site of mid-Waipara and the terrestrial site of Compressor C

Genetic prediction of postpartum diabetes in women with gestational diabetes mellitus

Aims: To examine whether genetic variants that predispose individuals to type 2 diabetes (T2D) could predict the development of diabetes after gestational diabetes mellitus (GDM). Methods: 13 SNPs (FTO rs8050136, CDKAL1 rs7754840 and rs7756992, CDKN2A/2B rs10811661, HHEX rs1111875, IGF2BP2 rs1470579 and rs4402960, SLC30A8 rs13266634, TCF7L2 rs7903146, PPARG rs1801282, GCK rs1799884, HNF1A rs116928

Origin and evolution of the mitochondrial proteome

The endosymbiotic theory for the origin of mitochondria requires substantial modification. The three identifiable ancestral sources to the proteome of mitochondria are proteins descended from the ancestral alpha -proteobacteria symbiont, proteins with no homology to bacterial orthologs, and diverse proteins with bacterial affinities not derived from alpha -proteobacteria. Random mutations in the f

Regulation of neuropeptide mRNA expression in the basal ganglia by intrastriatal and intranigral transplants in the rat Parkinson model.

Previous studies have shown that intrastriatal transplants of dopamine (DA)-rich fetal ventral mesencephalic (VM) tissue can correct denervation-induced changes in the cellular expression of neuropeptide and receptor mRNAs in the rat Parkinson model. However, with the standard transplantation approach normalization of all cellular parameters has not been obtained. This may be due either to the inc

The Art of Living with a Traumatic Spinal Cord Injury in its relation to Resources and Norms in Swedish Society

The overall aim of this thesis is to elaborate on the art of living with a traumatic spinal cord injury (SCI) in its relation to resources and norms in Swedish society. The thesis originates in part from a prevalence group of SCI individuals and is based on four studies. One is longitudinal and register based, and one is interview based. A paper on “ethics in the making” elaborates how general ver

Numerical Model of Beach Topography Evolution due to Waves and Currents: Special Emphasis on Coastal Structures

The beach topography change in the nearshore zone may be induced by natural phenomena such as wind, wave, storm, tsunami, and sea level rise. However, it can also be caused by man-made structures and activities, for example, groins, detached breakwaters, seawalls, dredging, and beach nourishment. Therefore, understanding the beach topography evolution in this zone is necessary and important for co

Studies of human endogenous retroviruses and of the TGF-beta signaling pathway

The human genome, in common with all mammalian genomes, carries a high load of inheritable retroviral sequences. We have identified and characterized a novel family of these endogenous retroviruses and have named this family HERV-F as based on the primer binding sites of three members. The HERV-Fs are C-type endogenous retroviruses that have unique gag, pol and env regions that are, based on phylo

Objective To assess the influence of age, sex, severity of hypertension and heart rate on t

The upper gastrointestinal tract in chronic alcoholics

Popular Abstract in Swedish Populärvetenskaplig svensk sammanfattning Symptom från mag- och tarmkanalen som smärtor , diarrè, illamåande och blödningar är vanliga hos personer som missbrukar alkohol. Orsaken till denna typ av besvär är emellertid något oklart. Alkohol tas upp i blodet från magsäcken och övre delen av tunntarmen. Således kan alkohol ha effekter på slemhinnan i mag- och tarmkanalen.Background: Gastrointestinal symptoms such as dyspepsia, diarrhoea, and nausea are often seen in alcoholics. The causes are not clear. The stomach and upper small intestine are exposed to high alcohol concentrations. Yet, the majority of alcohol abusers do not exhibit macroscopic abnormalities at upper gastrointestinal endoscopy, although histological and electron microscopic (SEM) changes have be

Lectin histochemistry of the gastric mucosa in normal and Helicobacter pylori infected guinea-pigs

Helicobacter pylori attaches via lectins, carbohydrate binding proteins, to the carbohydrate residues of gastric mucins. Guinea-pigs are a suitable model for a H. pylori infection and thus the carbohydrate composition of normal and H. pylori infected gastric mucosa was investigated by lectin histochemistry. The stomach of all infected animals showed signs of an active chronic gastritis in their mu
