PURPOSE: To determine whether there is any involvement of sympathetic nerves in the regulation of ocular hyaluronan production in the normal and traumatized rabbit iris. METHODS: Unilateral sympathetic denervation was performed by removing the right superior cervical ganglion. Hyaluronan concentrations in the iris and aqueous were measured with a radiometric assay at various time intervals after d

Wafer-level packaging (WLP) technology offers novel opportunities for the realization of high-quality on-chip passives needed in RF front-ends. This paper demonstrates a thin-film WLP technology on top of a 90-nm RF CMOS process with one 15-GHz and two low-power 5-GHz voltage-controlled oscillators (VCOs) using a high-quality WLP or above-IC inductor. The 5-GHz VCOs have a power consumption of 0.3

STUDY DESIGN: By using roentgen stereophotogrammetric analysis in six patients having tantalum indicators implanted at a preoperative external fixation test, the mobility in the spondylolytic lumbosacral level and its adjacent segment could be studied before fusion and during the course of postoperative fusion consolidation. OBJECTIVE: To study the mobility effects on the segment adjacent to a lum

Objective: The aim in this study was to assess the association between individual plasma carotenoid levels (alpha-carotene, beta-carotene, lycopene, beta-cryptoxanthin, lutein, zeaxanthin) and fruit and vegetable intakes recorded by a calibrated food questionnaire (FQ) and 24- h dietary recall records (24HDR) in nine different European countries with diverse populations and widely varying intakes

Termen ”kollektiv kollaps” förekommer relativt ofta på dagstidningarnas sportsidor, men inte i den idrottspsykologiska litteraturen. På grundval av beskrivningen av kollektiv kollaps i media föreslås följande definition: Kollektiv kollaps inträffar när en majoritet av spelarna i ett idrottslag plötsligt presterar under förväntad standard i en match av stor, ofta avgörande, betydelse trots en norma

Here, we review the use of actin-based motors, (myosins; e.g., the molecular motor of muscle) in. nanotechnology. The review starts from the viewpoints of the molecular motors as being important devices responsible of cargo transportation in the cell and end in discussions about their employment in nanotechnological applications. First, we describe basic biophysics of the myosin motors with focus

The main focus in this licentiate thesis is a description of the environmentally introduced action of diffusing and chemically reactive (e.g. carbonation and chemical-physical adsorption-desorption) matter in the pore solution and in the air-filled space in the pore system of the material. The governing equations describing the variation of concentrations of different substances and temperature wi

Using a numerical simulation of compressible convection with radiativetransfer mimicking the solar photosphere, we compare the velocity fieldderived from granule motions to the actual velocity field of the plasma.We thus test the idea that granules may be used to trace large-scalevelocity fields at the sun's surface. Our results show that this isindeed the case provided the scale separation is suf

Objectives. The aims of the present study were to analyze patient- and management-related predictors for outcome after open (OR) and endovascular repair (EVAR) of ruptured abdominal aortic aneurysm (rAAA). Design. Retrospective study. Materials. The in-hospital registry of Malmo University Hospital identified 162 patients operated on due to rAAA between 2000 and 2004. Methods. Patient- and managem

BACKGROUND: The importance of tobacco smoking and Helicobacter pylori infection as risk factors in the development of gastric carcinoma was investigated through multivariate conditional logistic regression analysis in a nested case-control study. METHODS: Blood samples and a questionnaire on smoking habits were collected from a cohort of 32,906 city residents during a health screening programme fr

The cytogenetic evolution of 32 Philadelphia (Ph)-positive chronic myeloid leukemias (CML) receiving interferon-alpha (IFN-alpha) therapy was compared to the patterns in untreated CML and cases treated with busulfan (Bu), hydroxyurea (Hy), and allogeneic bone marrow transplantation (BMT). Half of the CML receiving IFN-alpha had at least one of the well-known major or minor route aberrations wherea
