We have made in-situ investigations of ultrathin films of Fe grown on a Ag(100) single crystal. This system is known to exhibit a reorientation of the magnetization, dependent on both Fe thickness and temperature. X-ray absorption fine structure has been recorded for samples prepared in-situ, both in the near edge and in the extended x-ray absorption fine structure (EXAFS) region. Using x-ray magn

Max Weber’s model of charismatic authority, which was influenced by Rudolph Sohm’s interpretation of the earliest church as a ”charismatic organization”, has been more used by exegetes since 1968 as a help in interpreting Jesus. They have emphasized different aspects of his charisma — radical life-style and revolutionary message, or miraculous powers of healing, or conflict and self-stigmatization

The development of multicellular organisms is associated with extensive rearrangements of cells and tissues. The driving force for these rearrangements is generated by the cell's actin cytoskeleton. During many morphogenetic processes dynamic rearrangement of the actin cytoskeleton is regulated by small GTPases of the Rho-family. These GTPases are highly conserved throughout the animal kingdom and

This lecture focuses on the properties of synchrotron radiation. This subject is extensively treated in many excellent articles and textbooks. (See for instance [1, 2]). We have also excellent and user-friendly computer codes, as SPECTRA (Spring-8) and SRW (ESRF) which you can get on the net, so few of us are now actually using the analytic formulas to calculate radiation spectra. This lecture is

Studies have been made in 1407 patients of the causes, the organs involved and the outcome of injury to the abdomen in patients needing admission to hospital in an area of Southern Sweden, between 1950 and the end of 1979. The proportion of female patients and those aged over 60 increased significantly. The seasonal distribution of the injuries showed significant change, with a drop in the initial

To measure in vivo the cadmium concentrations in kidney cortex (kidney-Cd) and in superficial liver tissue (liver-Cd) of nickel cadmium battery workers, and to compare the results with other commonly used estimates of cadmium exposure (current concentrations of cadmium in blood (B-Cd) and urine (U-Cd)) or repeated measurements of cadmium in workplace air (CumAir-Cd). METHODS: The study comprised 3

Quick-release and quick-stretch experiments have been performed on preparations of smooth muscle from rat portal vein and rabbit urinary bladder. The low equivalent mass of the isotonic lever (8 mg) implied that inertial oscillations were limited to the first 5-10 msec after the load step. The high time resolution achieved in this way enabled us to separate three components in the length response

Background and aim: Diagnosis of coeliac disease is based on the demonstration of enteropathy in a small bowel biopsy. Correct diagnosis is of utmost importance, since the need for dietary management is life long, and inadequate treatment may lead to potentially serious complications. The Swedish Working Group for Paediatric Coeliac Disease has published guidelines for the diagnosis of childhood c

Experience gained from cooperation between dermatologists and vascular surgeons in 177 patients evaluated at a joint leg ulcer clinic is reported. Patients were divided into two subgroups: (i) 86 patients with healed ulcers and (ii) 91 patients with ongoing therapy-resistant ulcers. Venous insufficiency was the most common etiology in both subgroups (87% and 55%, respectively). Of previous therapy

Background. In a search for immunosuppressive drugs having novel mechanisms, monocarboxylate transporter (MCT-1) inhibitors were identified that markedly inhibited immune responses. Here, we report the effects of AR-C117977, a potent MCT-1 inhibitor, on alloimmune responses in the rat. Methods. In vitro activity was determined in a rat mixed lymphocyte response (MLR). In vivo activity was tested i

Human embryonic skin fibroblasts were pretreated with transforming growth factor-beta (TGF-beta) for 6 h and then labeled with [35S]sulphate and [3H]leucine for 24 h. Radiolabeled proteoglycans from the culture medium and the cell layer were isolated and separated by isopycnic density-gradient centrifugation, followed by gel, ion-exchange and hydrophobic-interaction chromatography. The major prote

Sequential isolates from eight cynomolgus monkeys experimentally infected with Simian immunodeficiency virus (SIVsm, of sooty mangabey origin) were tested for coreceptor use in the human osteosarcoma indicator cell line, GHOST(3), expressing CD4 and one or another of the chemokine receptors CCR3, CCR5, CXCR4, BOB, or the orphan receptor Bonzo. The indicator cell line carries the human immunodefici

In the Baltic Sea, floating blooms of nitrogen-fixing cyanobacteria occur yearly during late summer. These blooms can sometimes be limited by iron. Due to extensive foresting around the Baltic Sea, iron is entering the Baltic Sea partly bound to dissolved organic material (DOM) via rivers. An experiment was performed in 300 1 laboratory mesocosms to test the hypothesis that riverine high-molecular
