The dinoflagellates constitute a group within the protistan supergroup Alveolata, and can be referred neither to the plant nor the animal kingdom. They swim about using two flagella and orient using various stimuli. About half of the species are capable of oxygenic photosynthesis, but most of them complement this with capture of prey. Some live entirely by capturing small organisms, others are par

Various Helicobacter species have been isolated from the stomach, intestinal tract and liver of a variety of mammalian and some avian species, and Helicobacter DNA has been detected in human bile and liver samples. An immunoblot assay was established to analyse serum antibody responses to non-gastric Helicobacter species in patients with autoimmune liver diseases, in comparison with healthy indivi

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

Objective: To compare the healthcare costs and effects of budesonide/formoterol in,a single inhaler with those of budesonide and formoterol monotherapies, and placebo, in a multinational study in patients with chronic obstructive pulmonary disease (COPD), National Heart, Lung and Blood Institute (NHLBI)/WHO Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages III or IV.

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

Abstract. My main claim is that explanations are fundamentally about relations between concepts and not, for example, essentially requiring laws, causes, or particular initial conditions. Nor is their linguistic form essential. I begin by showing that this approach solves some well-known old problems and then proceeds to argue my case using heuristic analogies with mathematical proofs. I find that

Historically , the fire safety code systems now in force had to be written without actually stating their objective level of safety and, still far less , without any analytical measurement of the objectives involved. For this reason, there is an urgent need for future attempts to evaluate the levels of safety inherent in present local and national fire protection regulations. Lack of knowledge wit

Rotational bands have been found in Co-57 and Ni-57, using Gammasphere in conjunction with the Microball and 30 neutron detectors. The bands in Co-57, extending the mass 60 region of deformation down to Z = 27, are signature partner sequences. The quadrupole moments and dynamic moments of inertia of the new bands in both nuclei are similar to those of rotational sequences in the neighboring nuclei

Extractability of red pigment from red beetroot was investigated using pulsed electric field (PEF) treated tissue in a solid-liquid extraction process. Thin disks of the tissue were subjected to PEF at different intensities and, 3-4 min after the treatment, the release of red pigment and ionic species into an isotonic solution was measured in situ using a spectrophotometer and a conductivity meter

Deficiency of complement components within the classical pathway is associated with increased risk for immune complex disease. However, C2-deficient individuals often have a mild disease and about 50% are healthy. To study the importance of the different components for immune complex clearance, bovine serum albumin (BSA)/anti-BSA complexes were opsonized in human serum and the binding to erythrocy

Rheumatoid arthritis (RA) is an autoimmune disease characterized by a persistent inflammation of the synovium, leading to the erosion of articular cartilage and bone. Synovial mast cells and their effector molecule, histamine, receive increased attention as mediators of joint inflammation. The aim of our study was to analyse levels of free histamine in serum and joint fluid of RA patients and to e

The Anti-lock Braking System is an important component of the steeringsystem in a modern car. In the latestgeneration of brake-by-wire systems, the performance requirementson the ABS are much higher. The controllers have to be able to maintain aspecified tire slip for each wheel during braking. The authors proposea design model and based on that a gain-scheduled controller thatregulates the tire-s

54 human genes were selected as test targets for parallel cloning, expression, purification and crystallization. Proteins from these genes were selected to have a molecular weight of between 14 and 50 kDa, not to have a high percentage of hydrophobic residues (i.e. more likely to be soluble) and to have no known crystal structures and were not known to be subunits of heterocomplexes. Four proteins

Injectable bone substitutes (IBS) based on calcium phosphate (CaP) and/or calcium sulphate (CaS) are used as fillers in bone defects to stimulate bone integration and allow mechanical loading. Two types of IBS, IBS-1 is CaP+20%CaS and IBS-2 is CaS+40% hydroxyapatite, were investigated. The materials were injected into holes in the femur and tibia in rabbits. After 10 weeks the femora were subjecte
