OBJECTIVE--Steroid hormones, especially estrogens, are known to affect hemostatic risk factors for thromboembolism, cardiovascular disease, and stroke. We examined these risk factors during depression of the serum estradiol concentration by a GnRH analogue. DESIGN--Patients were treated with a GnRH analogue, goserelin (Zoladex), 3.6 mg/inj monthly, for a period of 6 months. Blood samples were coll

Den hälsomässiga effekten som rapporteras i samband med sjuka-hus syndromet (SBS), vars orsak är okänd, kan betraktas som ett mönster av icke specifika symptom såsom irritationer i ögon, näsa och mun, upplevelser av torra sletnhinnor och hud, hudrodnad, mental trötthet och upplevelse av svag men ihållande lukt. Aven exponeringar i inomhusluften kan beskrivas som ett mönster av en mängd olika ämnen

The main topic of the thesis is the generalization of some traditional module-theoretic homological applications to complexes of modules and to differential graded modules over differential graded rings. We introduce three possible generalizations of the classical notion of annihilator of an R-module. For linear functors D (R) -> D (R), preserving the triangulation, certain inclusion results for

A review of recent research, as well as new results, are presented on transition metal oxide clusters, surfaces, and crystals. Quantum-chem. calcns. of clusters of first row transition metal oxides have been made to evaluate the accuracy of ab initio and d. functional calcns. Adsorbates on metal oxide surfaces have been studied with both ab initio and semi-empirical methods, and results are presen

Objective A European concerted action (the EuroNatal study) investigated the background of differences in perinatal mortality between countries of Europe. The study aimed to determine the contribution of differences in quality of care, by looking at differences in the presence of suboptimal factors in individual cases of perinatal death. Design Retrospective audit study. Setting Regions of 10 E

The basic features of a simple radial position-sensitive detector design, construction and performance, are described in detail in this paper. The electronics and method used to correlate the position information from the spectrum recorded by the detector are presented. Monte Carlo simulations of the performance of the detector embedded in a time of flight analyser show that such an instrument ena

We consider homogeneous density functions for proving almost globalattractivity of the zero equilibrium in a homogeneous system. It is shownthat the existence of such a function is guaranteed whenthe equilibrium is asymptotically stable, or in the more general case, whenthere exists a nonhomogeneous density function for the same systemsatisfying some reasonable conditions. Results related to robus

The lack of a conserved tyrosine autophosphorylation site is a unique feature of the C-terminal Src-kinase, Csk, although this protein tyrosine kinase can be autophosphorylated on tyrosine residues in vitro and in bacteria. Here we show that human Csk is tyrosine phosphorylated in HeLa cells treated with sodium pervanadate. Phosphorylation in vivo occurs mainly at Tyr-184 and in vitro mainly at Ty

Infection with Vibrio cholerae is a significant problem in manydeveloping countries. Cultivation of Vibrio cholerae is used inproduction of CTB, which is a component in a cholera vaccine. Fed - batch cultivations with V. cholerae in defined mediahave been conducted and reproducible results were obtained. A probing feeding strategy developed by Åkessonfor E. coli cultivations has been tested.The pr

This paper addresses the question of why metal- deficient barium stars are not yellow symbiotic stars ( YSyS). Samples of ( suspected) metal-deficient barium ( mdBa) stars and YSyS have been collected from the literature, and their properties reviewed. It appears in particular that the barium nature of the suspected mdBa stars needs to be ascertained by detailed abundance analyses. Abundances are

OBJECTIVE: To evaluate clinical usefulness of cerebrospinal fluid stroke volume (SV) assessed in the cerebral aqueduct, via cine phase-contrast magnetic resonance imaging, for predicting outcome after shunt surgery in suspected normal pressure hydrocephalus. METHODS: Thirty-eight patients with suspected normal pressure hydrocephalus were included. SV was assessed using cine phase-contrast magnetic

This paper presents a method to calculate the forces in a chain and, thus, the resulting load distribution along the sprockets in a chain transmission working at a moderate or high speed. When the chain drive is loaded, the rollers that contact the sprockets will move along the flanks to different height positions. There are mainly two different ways to determine the actual positions: to assume th

Epidemiological studies have shown diet to be an important factor in the global variation of human cancer rates. The presence of mutagenic/carcinogenic heterocyclic aromatic amines (HAs) in cooked foods has attracted a great deal of interest for more than 20 years. Accurate assessment of the human exposure to HAs requires food questionnaires that address cooking methods and reliable methods for th

Methacrylate-functionalized poly(ethylene oxide-co-ethylene carbonate) macromonomers were prepared in two steps by the anionic ring-opening polymerization of ethylene carbonate at 180 °C, with potassium methoxide as the initiator, followed by the reaction of the terminal hydroxyl groups of the polymers with methacryloyl chloride. The molecular weight of the polymer went through a maximum after app

The aims of this study were to investigate the frequency of dysphagia among patients with acute stroke and compare non-dysphagic and dysphagic stroke patients regarding demographic aspects, performance in activities of daily living and type of neurological deficiency and to test a bedside screening tool to identify patients with dysphagia. The frequency of dysphagia was found to be 27%, or 40% if

The lateral ganglionic eminence (LGE) is known to give rise to striatal projection neurons as well as interneurons, which migrate in the rostral migratory stream (RMS) to populate the granule cell and glomerular layers of the olfactory bulb. Because all of these neuronal subtypes express Distalless-related (DLX) homeobox proteins during their differentiation, we set out to further characterize pro
