PURPOSE: To prospectively evaluate the usefulness of magnetic resonance (MR) imaging for estimating pulmonary blood volume (PBV) and the variation in PBV throughout the cardiac cycle in experimental heart failure. MATERIALS AND METHODS: The animal care committee approved this prospective study. Seven pigs were studied before and after myocardial infarction. PBV measurement was validated in a phant

OBJECTIVE: To investigate if placental Doppler velocimetry can predict the recurrence of a small-for-gestational age (SGA) fetus in subsequent pregnancies. DESIGN: Retrospective study. SETTING: City cohort over 15 years attending a university hospital. METHODS: A total of 196 pregnancies suspected of a SGA fetus (<3rd percentile) evaluated by uterine and umbilical artery Doppler velocimetry. Blood

The isomeric diazadithiapentacenes (3) and (4) were obtained in reactions of 2-chloro-3-bromoquinoline (5) with selected sulfur reagents in various conditions. The 1,4-dithiin ring opening in diazadithiapentacene (3) led to 2,3’-diquinolinyl sulfide or (via the Smiles rearrangement stage of the S→S type) to 3,3’-diquinolinyl sulfide or to diazadithiapentacene (4) depending on reaction conditions.

BACKGROUND: Job strain and the Arg389Gly polymorphism in the adrenergic beta1-receptor gene have been linked to hypertension. We aimed to study whether there is an interaction between the Arg389Gly polymorphism and job strain and its components (job demand and decision latitude) in relation to blood pressure. METHODS: From the Malmö Diet and Cancer population cohort, 6095 individuals were randomly

The existence of a uniform phase at the alveolar surface is demonstrated by polarizing microscopy and cryogenic transmission electron microscopy (cryo-TEM). Rabbit lungs were opened and the alveolar surface film was directly deposited on optical microscope coverslips and on electron microscope grids. In the polarizing microscope, the alveolar surface material deposited exhibits a uniform birefring

Pathogenicity of many microbes relies on their capacity to resist innate immunity, and to survive and persist in an immunocompetent human host microbes have developed highly efficient and sophisticated complement evasion strategies. Here we show that different human pathogens including Gram-negative and Gram-positive bacteria, as well as the fungal pathogen Candida albicans, acquire the human term

Popular Abstract in Swedish Denna avhandling ger ett bidrag till teorin om strategisäkra kollektiva beslut. I denna teori undersöks under vilka förutsättningar det är möjligt att konstruera omröstningsprocedurer (hädanefter kallade för kollektiva valfunktioner) som är strategisäkra i den bemärkelsen att ingen väljare kan ändra utfallet av en omröstning till sin fördel genom att inte rösta enligt sThis thesis makes a contribution to strategy-proof social choice theory, in which one investigates the conditions under which it is possible to construct social choice functions (i.e., voting procedures) that can never be manipulated in the sense that some voter, by misrepresentation of his true preferences, can change the outcome of a voting and obtain an alternative he prefers to the one that ho

PURPOSE: To prospectively register and report the hand function and occupational performance of patients with proximal interphalangeal joint-pyrocarbon arthroplasty, using both objective tests and subjective outcome instruments. METHODS: From 2004 to 2008, 53 joints in 43 patients were reconstructed with a proximal interphalangeal joint-pyrocarbon prosthesis. The patients underwent a rehabilitatio

This paper presents a framework for assessing alignment between corporate strategy, procurement strategy and purchasing tools. The framework is built on generation of rents as its common denominator for assessing alignment between the levels. Three types of rents are identified: monopoly rents; Ricardian rents and entrepreneurial rents. The framework is then used for assessing the strategic origin

With the increasing interest in the use of biofuels for heat and energy generation there is a growing concern about emissions from their combustion. It has been shown that biofuel furnaces emit relatively high quantities of particulate matter in comparison to natural gas and light fuel oil furnaces. Majority of the emitted particulates are smaller than 10 μm with high contribution of fine (< 2.5 μ

The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. To meet this demand, a relocation of the DSL transceivers in cabinets closer to the customers

To explore the experiences over time of using mobility devices (MDs) among very old women in the context of everyday life in Latvia.

Context: It has been shown that mitochondrial DNA (mtDNA) content is associated with type 2 diabetes (T2D) and related traits. However, empirical data, often based on small samples, did not confirm this observation in all studies. Therefore, the role of mtDNA content in T2D remains elusive. Objective: In this study, we assessed the heritability of mtDNA content in buccal cells and analyzed the ass

Lifetime determinations for eleven levels in La II and two levels in La III have been performed using time-resolved laser spectroscopy. Free La+ and La++ ions were produced in a laser-induced plasma and selective excitation was obtained with narrow-bandwidth, 1 ns duration tunable laser pulses. Lifetime values were evaluated from the time-resolved fluorescence signals recorded by a fast detection
