In the water-oxidizing reactions of photosystem II (PSII), a tyrosine residue plays a key part as an intermediate electron-transfer reactant between the primary donor chlorophylls (the pigment P-680) and the water-oxidizing Mn cluster. The tyrosine is deprotonated upon oxidation, and the coupling between the proton reaction and electron transfer is of great mechanistic importance for the understan
Site I of antigenic domain 2 (AD-2) on human cytomegalovirus glycoprotein B (gB) is poorly immunogenic in both man and mouse and knowledge about antibody repertoires reactive with this epitope is thus limited. Here we have characterized a phage display-derived repertoire of antibody fragments specific for this epitope in terms of antigen recognition, fine-specificity, and virus-neutralizing capaci
This book deals with ’have’ in ancient Greek. Two different types of ’have’-constructions were used, viz., on the one hand, the active transitive verb ἔχω and, on the other hand, the verb εἶναι, ’be’, with a complement in the dative case (here called the ἔστι μοι construction). A transitive ’have’ does not seem to be of Proto-Indo-European origin but rather an innovation in separate Indo-European
The cost of energy for drying paper is substantial for the pulp and paper industry, and studies of various strategies for energy cost reductions such as increased energy efficiency, increased heat recovery from the exhaust drying air and reduced cost of the process heat are presented in this thesis. The energy use and cost studies were performed using a block-model based simulation tool developed
We review a neck method to explore the cellular functions in multicellular system by application of the perforated patch-clamp technique to intact pancreatic islet of Langerhans. Using this approach, the integrity of the islet is preserved and intercellular communication via gap junctions and paracrine processes are maintained. 13 using low-resistance patch electrodes, rapid current responses can
It is widely accepted that the bioavaiiability, toxicity, and mobility of trace metals are highly dependent on complexation reactions with functional groups in natural organic matter (NOM). In this study, the coordination chemistry of Cd in NOM was investigated by extended X-ray absorption fine structure spectroscopy. Soil organic matter (SOM) from different types of organic soils and dissolved or
There is no general agreement on the spirometric definition of chronic obstructive pulmonary disease (COPD). The global initiative for obstructive lung disease recommends a fixed ratio between forced expiratory volume in one-second (FEV1 ) and forced vital capacity (FVC) of <0·7 (FR) for the diagnosis of COPD. European Respiratory Society and American Thoracic Society favour the use of the fifth p
Fluorescence spectroscopy is one of many optical methods that are potentially clinically useful for noninvasive detection and characterization of disorders on the cervical part of uterus, including precancerous lesions. The cervix uteri exhibits a biologically complex tissue and the morphology of a biopsy is generally not homogenous. The standard histopathological protocol accounts only for the mo
Abstract Purpose: To evaluate the midterm outcomes and potential risk factors associated with the fascia suture technique (FST) for closure of femoral artery access sites after percutaneous endovascular aneurysm repair (EVAR). Methods: Between April 2007 and April 2008, 100 consecutive EVAR cases were evaluated retrospectively. A third of the procedures were emergent (16 ruptured aneurysms). Of th
Down-core sediment pigment concentrations from four Northern European estuaries were measured using high-performance liquid chromatography (HPLC) to investigate phytoplankton community structure and preservation conditions over the last ca. 100 years where all sites have experienced different levels of eutrophication. Phytoplankton pigments have been shown to be useful biomarkers for phytoplankton
INTRODUCTION: D-dimer assays are now widely used as the first-line test in the diagnostic algorithm of suspected deep vein thrombosis (DVT). The aim of this study was to evaluate the performance of two relatively new quantitative D-Dimer assays (Innovance and AxSYM(R)) by comparison with a clinical gold standard. PATIENTS AND METHODS: 311 samples from outpatients with clinical suspicion of DVT, in
BACKGROUND: Current studies reveal a lack of consensus for the evaluation of physical and psychosocial problems after ICU stay and their changes over time. OBJECTIVES: The aim was to develop and evaluate the validity and reliability of a questionnaire for assessing physical and psychosocial problems over time for patients following ICU recovery. PATIENTS: Thirty-nine patients completed the questio
Radiative lifetimes for six highly excited levels in Fe II have been measured at Lund Laser Centre applying the laser induced fluorescence technique and two-step excitation. The energy levels belong to the even-parity 3d(6)(D-5)(4)d subconfiguration at about 10 eV. Branching fractions (BF:s) of 29 transitions from these levels to the 3d(6)(D-5)4p subconfiguration at about 5 eV have been measured i
Abstract When studying the deposition of particles in wind tunnel experiments, we measure theairborne particles with an Aerodynamic Particle Sizer (APS). The deposited particles are examined with an optical microscope connected to an image analyzer. Calibration between the APS and the optical microscope determinations of particle size has been performed for particles of fused alumina. The particle
This nationwide study aimed to determine whether differences exist in age-specific and sex-specific familial risks for pulmonary embolism (PE), venous thrombosis of the lower limbs (VT) and other forms of venous thromboembolism (OVTE) among offspring, siblings and spouses of affected individuals. The Swedish Multi-Generation Register was linked to the Hospital Discharge Register data for the perio
Lumbar spine radiography is often performed instead of CT for radiation dose concerns.
Using the concepts of social norms and social reality, this chapter explores why legal reforms that aimed to facilitate the formalization of informal workers have largely failed to influence vulnerable groups in developing countries. It explores the use of legal reforms in order to achieve development and poverty reduction. Using empirical material from a qualitative study conducted in Colombia am
