Three healthy young male subjects were given a single load of ethanol (approximately 3 g/kg body weight) over 5 hours. Liver aspiration biopsies were performed at the start of the experiment and 6, 14, 24, and 48 hours after the start. Blood alcohol and serum transaminase activity levels were measured simultaneously. Triglycerides and phospholipids of the liver biopsy material were determined by a
Acetals are efficiently hydrolyzed with silica gel‐supported pyridinium tosylate moistened with water in solvent‐free conditions under microwave irradiation. The method is efficient and mild, with acid‐sensitive 3‐hydroxyacetals and 3‐methoxyacetals being hydrolyzed in minutes in good yields.
In recent years it has been demonstrated that loud clicks generate short latency vestibular evoked myogenic potentials (VEMP). It has also been demonstrated that skull tap stimulation evokes similar VEMP. In the present study, the differences between the click-induced and the skull-tap induced VEMP were studied in 18 patients at onset of vestibular neuritis. Gentle skull taps were delivered manual
Abstract in French La porosimétrie par succion repose sur la mesure de la dépression capillaire que suscite un liquide mouillant retenu dans un milieu poreux. C’est donc une méthode complémentaire à celle de la porosimétrie par pression (par ex. pénétration de mercure) où l’on opère avec des liquides mouillants. On expose la théorie et la pratique des méthodes par succion, entre autres les méthodeThe theory and practice of suction porosimetry methods (suction plate, pressure membrane and centrifuge) are reviewed together with related methods based on the rate of penetration of wetting liquids, and on static and dynamic fluid/fluid displacement measurements.
En läsning av Bruno K. Öijers författarskap som ett försök att bekämpa förtryck; detta sker via två vägar eller metoder: anarki och magi. Ytterst är poesin den kraft där dessa vägar sammanstrålar till fullo. Både textanalys och biografiska tolkningar ingår i mitt upplägg.
This article introduces' the concept of distributed economies (DE) as a fresh strategy to guide industrial development towards becoming more sustainable. The concept calls for a transformation in the industrial system towards DE departing from the socio-economically and environmentally unsustainable dynamics associated with large-scale, centralised production units that are favoured by neoclassica
The article presents an experiment in which students, classified according to high and low analytical performance, were given a reading and text production test to determine their sensibility to the structure of an Icelandic saga. This material was used because of its extreme simplicity on the textual surface level, a property suited for studying structure as something beyond the surface. The hypo
In order to determine the clinical significance of decreased fetal movement counts, pregnancy outcome was compared between women with decreased fetal movement counts on their Fetal Movement Charts (FMC) (n = 161) and women with normal fetal movement counts (n = 1,354). 1,515 women in the third trimester of pregnancy counted fetal movements for 15 min in the evening and noted the count on a FMC. An
Cystatin F is a recently discovered type II cystatin expressed almost exclusively in immune cells. It is present intracellularly in lysosome-like vesicles, which suggests a potential role in regulating papain-like cathepsins involved in antigen presentation. Therefore, interactions of cystatin F with several of its potential targets, cathepsins F, K, V, S, H, X and C, were studied in vitro. Cystat
Genetic alterations, such as p53 mutations, may affect a tumour's response to chemotherapy. We have treated two human breast cancer cell lines that differ in p53 status with epirubicin in order to study if there are differences in cell cycle kinetic response. MCF-7 cells express wild-type p53, while SK-BR-3 cells express only a mutated form of p53. The transition of cells from one cell cycle stage
We have shown in a computational model that a poor memory for context could result in some of the behaviors associated with ADHD, which is well in line with the dynamic developmental theory. Given the important role of context in extinction, a weaker context due to a steeper delay-of-reinforcement gradient would result in impaired inhibition.
In the rat eye, intracameral injections of substance P in doses of 10-30 pmol caused a maximal long-lasting miosis and a leakage of plasma proteins into the aqueous humor, indicating a breakdown of the blood-aqueous barrier. Neurokinin A seemed equipotent to SP, but calcitonin-gene-related peptide (CGRP) (17 pmol) caused neither miosis nor protein leakage into the aqueous humor. The same result wa
Popular Abstract in Swedish Syftet med denna avhandling är att undersöka varför och hur skogsbruk införs i Sverige under 1800-talet och vilka konsekvenser det har under perioden. Med skogsbruk avses den systematiska odling av högskog som sprids från Tyskland från 1700-talets slut. De konsekvenser som avses är de naturförändringar och de sociala konflikter som skogsbruket medför liksom de nya värdeThe aim of this dissertation is to investigate how and why silviculture was introduced in Sweden in the nineteenth century and the consequences this introduction had during the same period. The term silviculture refers to the systematic cultivation of high forest, a method that spread from Germany at the end of the eighteenth century. The consequences referred to are the changes in nature and the
