Long-term neuroblast migration along blood vessels in an area with transient angiogenesis and increased vascularization after stroke

Background and Purpose - Stroke induced by middle cerebral artery occlusion (MCAO) causes long-term formation of new striatal neurons from stem/progenitor cells in the subventricular zone (SVZ). We explored whether MCAO leads to hypoxia, changes in vessel density, and angiogenesis in the ipsilateral SVZ and adjacent striatum, and determined the relation between the migrating neuroblasts and the va

Feasibility of noninvasive transthoracic echocardiography/Doppler measurement of coronary flow reserve in left anterior descending coronary artery in patients with acute coronary syndrome: A new technique tested in clinical practice

Objective: The aim of this study was to test the feasibility and accuracy of transthoracic Doppler echocardiography measurement of coronary flow reserve (CFR) in the left anterior descending coronary artery (LAD) territory in the clinical setting of the acute coronary syndrome. Methods: Transthoracic Doppler echocardiography measurements of CFR were made in 42 consecutive patients in the distal LA

Time geography: a model for psychiatric life charting?

Since many years, life charting has been used to describe the life course and life events of psychiatric patients. The aim of the present study was to describe and evaluate time geographic life. charts of 11 former psychiatric patients in order to promote systematic descriptions of their life events over time. Information on all events which was gathered from the life charts was analysed by manife

The influence of permeant and membrane properties on mass transfer in pervaporation of volatile organic compounds from dilute aqueous solutions

In this study, a dilute mixture of volatile organic compounds in aqueous solution was separated by means of hydrophobic pervaporation, using three different poly(octylmethyl siloxane) membranes of various thicknesses. The permeabilities were determined for homologous series of compounds from the chemical groups of alcohols, esters, and aldehydes, and they were then related to some characteristic p

Changes in biologically active ultraviolet radiation reaching the Earth's surface

Stratospheric ozone levels are near their lowest point since measurements began, so current ultraviolet-B (UV-B) radiation levels are thought to be close to their maximum. Total stratospheric content of ozone-depleting substances is expected to reach a maximum before the year 2000. All other things being equal, the current ozone losses and related UV-B increases should be close to their maximum. I

Effects of magnesium and glucose, insulin, potassium (GIK) solution on the action potential parameters of guinea-pig atrial muscle

The present paper aims to explore the effects of [Mg2+]o and glucose, insulin and K+ (GIK) on action potential parameters in guinea-pig atrial muscle. Specimens of atrial appendages were taken from guinea-pig hearts. Action potentials were recorded in isolated atrial trabeculae. Resting potential (RP) and action potential duration at 90% repolarization (APD90) were measured with conventional micro

Thermal properties of three sets of garments measured with a heated sweating mannequin

The choice of proper insulation for cold protection is important. However, “proper insulation” depends on activity and at lots of jobs the activity varies along the working day. The choice of low insulation for high metabolic rate makes people feel cold during low activity levels and the choice of high insulation for low metabolic rate makes them feel hot and sweat during high activity levels. The

Transcranial cerebral oximetry related to transcranial Doppler after aneurysmal subarachnoid haemorrhage

Noninvasive methods for detecting cerebral artery vasospasm, still a serious complication following aneurysmal subarachnoid haemorrhage, are of vital interest. Up-to-date transcranial Doppler ultrasound (TCD) has proved to be sensitive in detecting vasospasm in the middle cerebral artery, but has less accuracy for other cerebral arteries. Transcranial cerebral oximetry (TCCO) is a new non-invasive

World Christianity and Inter-Religious Relations: Missionsvetenskap med Ekumenik:

The article discusses contemporary trends in the Mission and Ecumenical Studies in the context of World Christianity and Inter-Religious Relations. It engages with late 20th century scholarship, particularly relating to Christianity in Africa and Asia, and interacts with the paradigm-analysis of Mission Studies as advanced by David.J.Bosch in his Transforming Mission: Paradigm Shifts in Theology o

Persistence of plasmid RP4 in Pseudomonas putida and loss of its expression of antibiotic resistance in a groundwater microcosm

We examined the stability of plasmid RN and its expression of antibiotic-resistance genes in suspended and sorbed Pseudomonas putida in aquifer microcosms. Test tubes containing different proportions of sterilized aquifer soil and groundwater were inoculated with bacteria and incubated for up to 26 d. Serial dilutions were made to agar plates with or without antibiotics, to quantify the functional

Role of wave velocity for encountered wave statistics

Encountering waves overtaking a ship sailing on the ocean may cause instability. Therefore it is of great importance to study the properties of such waves, for example slope, wavelength and amplitude. When making statistics on the properties of overtaking waves, only the waves that are faster than the ship will affect the resulting distribution. Thus the velocity of the individual waves plays an i

Att förebygga livmoderhalscancer: Gynekologisk cellprovtagning samt vaccination mot Papillomvirus.

En förutsättning för insjuknande i cervixcancer är en infektion med genitalt papillomvirus - HPV. Sjukdomen uppstår efter åratal av förstadier, som kan upptäckas genom cervixcytologi/gynekologisk cellprovstagning och stoppas med behandling. I Sverige har cellprovstagningen minskat förekomsten av livmoderhalscancer med 50 procent. I Finland, där man använder organiserad screening, har förekomsten
