Every living cell is surrounded by a cell membrane that is made up of amphipathicphospholipids, separating the aqueous solutions inside and outside the cell with ahydrophobic barrier. This compartmentalization is a prerequisite for life, but so arethe many molecules that are floating in the membrane, altering its properties andconnecting the inside with the outside. An important group are the tran
The Web Accessibility Directive (WAD) is part of the European Union’s work for digital inclusion. The WAD obligates that public sector bodies’ websites meet accessibility standards and provide an accessibility statement on the website informing about inaccessible content, and a feedback mechanism for reporting accessibility issues or requesting inaccessible content in an accessible format. The obj
Background: Cognitive impairment is common following out-of-hospital cardiac arrest (OHCA), but the nature of the impairment is poorly understood. Our objective was to describe cognitive impairment in OHCA survivors, with the hypothesis that OHCA survivors would perform significantly worse on neuropsychological tests of cognition than controls with acute myocardial infarction (MI). Another aim was
The functional role of the GGN repeat in the human androgen receptor gene is unknown, although mutations in this region have been found in patients with inter-sex conditions. We have investigated the prevalence of GGN mutations in the androgen receptor in the Swedish population and their relation to male reproductive function. A physical examination and semen analysis was carried out in 223 men un
The influence of washing chemicals used at car washes on the flux and retention of three ultrafiltration (UF) membranes has been studied. Eleven commercial degreasing agents, two shampoo agents and a wax were included in the investigation. The membrane performance when treating waste water collected at a car wash at different times of the year was also studied. The retention of the different chemi
Human plasma samples from 50 wives of fishermen have been analyzed with respect to PCBs. The non-ortho-substituted PCB congeners CB-126 and CB-169 were determined by mass spectrometry in negative ion chemical ionization mode, which demonstrated a limit of detection of 30 fg. The recoveries of the internal standards used for determination of ortho-substituted CBs were approximately 95%. Two methods
Lake Urmia in north-western Iran is one of the largest hypersaline lakes in the world, and agricultural production in the surrounding area is limited by soil salinity. We investigated the effects of salinity on belowground microbial communities in soils collected from fields of cultivated onions (Allium cepa L.) and lucerne (Medicago sativa L.), and sites with the native halophyte samphire (Salico
This dissertation deals with reactive components in electric circuits, both as targets for a theoretical circuit analysis, and as devices implemented in silicon processes like CMOS. The frequency behavior of a general electric network is determined by the reactances (i.e., inductances and capacitances) present in the network, either as intentional parts of the design, or as process and implementa
Background: Insulin is a therapeutic protein that is widely used for the treatment of diabetes. Its biological function was discovered more than 80 years ago and it has since then been characterized extensively. Crystallization of the insulin molecule has always been a key activity since the protein is often administered by subcutaneous injections of crystalline insulin formulations. Over the year
Neutral Pb clusters in the size range from a few tens of atoms up to similar to 100 atoms are studied using synchrotron-based photoelectron spectroscopy. The electronic structure is seen to differ increasingly from that of the solid when the cluster size decreases. The valence band narrows gradually - down to about one fifth of the solid-state band width at the smallest size of few tens of atoms.
We study a model of the atrioventricular node function during atrial fibrillation (AF), for which the model parameters can be estimated from the ECG. The proposed model is defined by parameters which characterize the arrival rate of atrial impulses, the probability of an impulse choosing either one of the two atrioventricular nodal pathways, the refractory periods of these pathways, and the prolon
Dwarf males (nannandry) occur in many unrelated, mostly aquatic, groups of organisms. Among land plants they are unique to bryophytes. In this study our aim was to explain variation in frequency of dwarf males and fertilization within populations in the moss Homalothecium lutescens. We compared parameters related to dwarf male presence and sporophyte production in 90 colonies from three localities
Gadodiamide injection, a new nonionic, MRI contrast medium, was compared with the ionic agent gadolinium (Gd)-DTPA at 0.1 mmol/kg body weight in a double-blind, randomised trial in 60 patients, 30 receiving each substance, with known or suspected lesions of the central nervous system. The patients were closely questioned about adverse events. In the Gadodiamide injection group, four patients repor
Popular Abstract in Swedish Beständiga organiska miljögifter, till exempel PCB (Polyklorerade bifenyler), har vållat stora miljöproblem i flera decennier. Dessa föroreningar är kemiskt och biologiskt sett väldigt stabila, vilket gör att de bryts ner mycket långsamt i miljön och alltså kan transporteras långväga med vindar och strömmar. Därför kan man hitta PCB över hela jorden, även i områden där Persistent organic pollutants (POPs) pose serious threats to our global environment. These compounds have high chemical and biological stability and they are also very lipophilic. These characteristics not only render POPs the ability to spread widely and pollute remote areas, they also make them prone to accumulate in adipose tissues of living organisms. Consequently, it is important to monitor P
Acquired clonal chromosome aberrations, closely associated with leukemogenesis, are found in many hematologic malignancies. Although the balanced rearrangements, such as translocations and inversions, are the ones most commonly thought of in the context of leukemias, gains of chromosomes ? e.g.., trisomies ? are also frequent. Little is known about the biologic outcome, the pathogenetic significan
Many clinics in rural western Kenya lack access to safe water and hand-washing facilities. To address this problem, in 2005 a programme was initiated to install water stations for hand washing and drinking water in 109 health facilities, train health workers on water treatment and hygiene, and motivate clients to adopt these practices. In 2008, we evaluated this intervention's impact by conducting
