Thyrostimulin (a TSH-like Hormone) Expression in Orbital and Thyroid Tissue.

Objective: To investigate gene expression of thyrostimulin in orbital and thyroid tissue from patients with and without Graves' disease. Design: Real-time reverse transcriptase polymerase chain reaction (RT-PCR) was used for detection of thyrostimulin gene expression in intraorbital adipose tissue from patients with severe ophthalmopathy and thyroid healthy controls in addition to thyrostimulin ex

Photosynthetically oxygenated acetonitrile biodegradation by an algal-bacterial microcosm: a pilot-scale study

A 43-L column photobioreactor wash tested for the treatment of acetonitrile Using a symbiotic consortium consisting of a Chlorella sorokiniana strain and a Comamonas strain. Complete biodegradation of 1 g acetonitrile/l was achieved in 79 hours under continuous illumination at 500 mu E/m(2) s and 26 degrees C. When the photobioreactor was operated at 26 degrees C under a 14/10 hours light/dark ill

A general model for calculating pressure drop in siphons and siphon riser tubes. Part 1: Principles and theoretical model

A general model for pressure drop calculations in siphons and riser tubes has been developed. The model takes into account different physical flow phenomena such as inlet pressure drop and pressure drop in the tube. For each phenomenon, we applied theory and established correlations to calculate the separate accelerational, frictional, gravitational, and centrifugal pressure drops. Model results a

Uttorkning av betong : inverkan av cementtyp, betongkvalitet och omgivande fuktförhållanden

Uttorkning av betong är ett ämnesområde som under lång tid varit i fokus. Genom åren har många skadefall kunnat kopplas till alltför fuktiga betonggolv. Det är inte betongen som tar skada utan vissa material som placerats i direkt anslutning till betongen. Exempel är kemisk nedbrytning av lim under plastmattor, vilket skapat kemiska emissioner som vandrat ut till inomhusluften, eller som lett till

The Politics of Popular Identity: Understanding Recent Populist Movements in Sweden and the United States

While populism and populist politics have been the focus of a wide range of studies in the social sciences, few analyses of populist phenomena have moved beyond the level of simple description. This study has three immediate aims: to critique existing theories of populism, to develop a new, analytical view of populism, and apply this view comparatively to two cases. This new view of populism emer

Microcolumn chromatofocusing using slurry-packed Mono P anion-exchanger beads as chromatographic matrix

Chromatofocusing of proteins in a microcolumn format (750 mum i.d.) was evaluated with slurry-packed Mono P anion-exchanger beads (10 pin bead size) as chromatographic matrix. Evaluation was performed with three standard proteins in terms of flow rate, Polybuffer 96-acetic acid, pH 6.0, concentration (eluent buffer strength), and detection limit. A column with the dimension 750 pin i.d. x 50 mm le

Self-rated health as a predictor of disability pension and death--a prospective study of middle-aged men

OBJECTIVE: Self-rated health (SRH) is increasingly attracting attention as a predictor of morbidity and mortality while its relation to impaired function has been given less momentum. The aim of this study was to assess the relation between SRH and the risk of being awarded a disability pension and premature death. METHODS: Five birth-year cohorts of middle-aged men were invited to a screening pro

Search for doubly-charged Higgs boson production at HERA

A search for the single production of doubly-charged Higgs bosons H-+/-+/- in ep collisions is presented. The signal is searched for via the Higgs decays into a high mass pair of same charge leptons, one of them being an electron. The analysis uses up to 118 pb(-1) of ep data collected by the H1 experiment at HERA. No evidence for doubly-charged Higgs production is observed and mass dependent uppe

In vitro effects of a thromboxane A2-analogue U-46619 and noradrenaline on contractions of the human thoracic duct

A piece of a human thoracic duct removed at operation was investigated in organ baths. The duct was cut in 8 ring segments each about 1mm long and isometric tension recorded. The segments were exposed to a potassium rich (124mM) Krebs buffer solution. In only two of the segments were contractions induced (7.2 and 1.0mN, respectively). Noradrenaline and the thromboxane mimetic U-46619 induced tonic
