This thesis deals with cerebral arterial vasospasm and ischaemia, a serious complication after aneurysmal subarachnoid haemorrhage. Firstly is the noninvasive transcranial Doppler ultrasound and transcranial cerebral oximetry techniques evaluated in detecting cerebral arterial vasospasm in clinical practice. Patients were examined during first 14 days after the bleed. Flow velocities in normo- ver

Popular Abstract in Swedish Muskelömhet hos kvinnor Smärttrösklar för tryck i skuldermuskulaturen (trapezius och deltoideus) i vila, efter muskel uttröttning och efter smärtsam stimulering Smärta i muskler och leder och besvär i form av upplevd trötthet i musklerna är vanligt förekommande problem, särskilt hos den kvinnliga delen av befolkningen. Man har ansett detta kopplat till olika belastandeLongstanding pain experienced from the musculoskeletal system is reported by one third of the Swedish population. The underlying mechanisms are not known in the majority of cases. In the present studies, the changes in pressure pain thresholds (PPTs) over the trapezius and deltoid muscles after a unilateral static contraction of maximal duration of one arm was measured in healthy females (n=25) a

Methods for monitoring seepage and detecting internal erosion are essential for the safety evaluation of embankment dams. Internal erosion is one of the major reasons for embankment dam failures, and there are several tenths of thousands of large embankment dams in the world. Internal erosion is progressing inside the dam, and is sometimes difficult to detect by conventional methods. Therefore, th

Popular Abstract in Swedish Optoelektronik genomgår för närvarande en otrolig utveckling, inte minst på grund av de senaste årtiondenas kommersialisering och utveckling av hemelektronik som kompaktdiskar och digitalkameror. Denna utveckling har drivit en blomstrande global tillväxt för optoelektroniska företag som varje år utvidgar sina erbjudanden av optiska komponenter i hård konkurrens. UtvecklThe present thesis describes a number of aspects of modern electro-optical measurement technology also known as bio-photonics; this includes instrumentation, applications, sample interaction and data interpretation. The methods employed operate over several domains, and light measurements are discretized both in intensity, space, angle, time, polarization and energy. Mainly the spectral domain is

Popular Abstract in Swedish Kroppens rörelser åstadkommes genom sammandragning av muskelvävnad som kan vara av två slag, glatt eller tvärstrimmig. Den senare sorten kan indelas i skelett och hjärtmuskulatur, vilka har mycket olika egenskaper trots den gemensamma benämningen. Muskelvävnaden är uppbyggd av långsträckta, spolformade celler som innehåller tunna och tjocka kontraktila filament, beståenThe initial signal for contraction in smooth muscle is an increase in [Ca2+]i. Ca2+ ions can either enter the cytosol from the extracellular medium or be released from intracellular stores. Voltage-operated Ca2+ channels (VOC) play a dominant role in the activation of smooth muscle contraction. This thesis describes two novel regulatory mechanisms of the dihydropyridine (DHP)-sensitive VOC in smoo

Popular Abstract in Swedish Glukos är den främsta energikällan för de flesta celler i kroppen. Det är av stor vikt att mängden glukos hålls på en jämn nivå, eftersom framförallt våra celler i hjärnan är mycket känsliga för stora variationer av glukoshalten i blodet. Regleringen av mängden glukos i blodet kontrolleras av hormonen insulin och glukagon. Insulin utsöndras från beta-celler och glukagonType-2 diabetes is characterized by impaired insulin secretion associated with excess glucagon release. Exocytosis of insulin- or glucagon-containing granules is initiated by Ca2+-influx through voltage-dependent Ca2+-channels and is modulated by the second messengers such as cAMP. Membrane capacitance measurements were used in this study to investigate the cellular mechanisms behind cAMP-regulate

Vapor pressures of five methyl-substituted dicarboxylic acids are inferred from measurements of evaporation rates of sub-micron particles using the TDMA technique at ambient temperatures. Vapor pressures values are given. These vapor pressures are compared witha vailable literature data and withv apor pressures of the un-substituted acids. Our results demonstrate that molecular structure is import

This dissertation examines the role of modernism and modernity in Chinese spoken drama and film during the years between the May Fourth Movement and the beginning of the Second Sino-Japanese War. This influence is traced through close readings of a selection of works in different categories, underlining relevant themes and structures that are recurring in both drama and film.

Different causes, such as maternal diabetes, cloning by nuclear transfer, interspecific hybridization, and deletion of some genes such as Esx1, Ipl, or Cdkn1c, may underlie placental overgrowth. In a previous study, we carried out comparative gene expression analysis in three models of placental hyperplasias, cloning, interspecies hybridization (IHPD), and Esx1 deletion. This study identified a la

Sugarcane bagasse-a residue from sugar and ethanol production from sugar cane-is a potential raw material for lignocellulosic ethanol production. This material is high in xylan content. A prerequisite for bioethanol production from bagasse is therefore that xylose is efficiently fermented to ethanol, In the current study, ethanolic fermentation of steam-pretreated sugarcane bagasse was assessed in

Objective. Our hypothesis states that the reactivity of the cutaneous microcirculation is reduced in patients with hypertension compared with healthy subjects. The objective was to verify the hypothesis by measuring microvascular function in hypertensive patients. Design. The study was a controlled trial with two arms: 15 hypertensives and 15 normotensives were enrolled, aged 30-60 years, and in h
