Ionization-site effects on the photofragmentation of chloro- and bromoacetic acid molecules
Fragmentation of gas-phase chloro-and bromoacetic acid samples, particularly its dependency on the atomic site of the initial core ionization, was studied in photoelectron-photoion-photoion coincidence (PEPIPICO) measurements. The fragmentation was investigated after ionizing carbon 1s and bromine 3d or chlorine 2p core orbitals. It was observed that the samples had many similar fragmentation path

Zhang S, Rahman M, Zhang S, Qi Z, Herwald H, Thorlacius H. Simvastatin regulates CXC chemokine formation in streptococcal M1 protein-induced neutrophil infiltration in the lung. Am J Physiol Lung Cell Mol Physiol 300: L930-L939, 2011. First published March 25, 2011; doi:10.1152/ajplung.00422.2010.-Streptococcus pyogenes of the M1 serotype can cause streptococcal toxic shock syndrome and acute lung
No Association of LOXL1 Gene Polymorphisms with Alzheimer's Disease
Aggregation of amyloid-beta is one of the major characteristics in brains of patients with Alzheimer's disease (AD). Although several mechanisms behind the formation of such aggregates have been suggested the regulatory factors are still unknown. The present study aimed at investigating the association of lysyl oxidase-like 1 (LOXL1) polymorphisms with AD diagnosis and cerebrospinal fluid biomarke
Alpha/Beta Oscillations Indicate Inhibition of Interfering Visual Memories
Abstract in UndeterminedSelective retrieval of a specific target memory often leads to the forgetting of related but irrelevant memories. Current cognitive theory states that such retrieval-induced forgetting arises due to inhibition of competing memory traces. To date, however, direct neural evidence for this claim has not been forthcoming. Studies on selective attention suggest that cortical inh
Modeling for transboundary water resources planning and allocation: the case of Southern Africa
International water resources agreements for transboundary rivers in southern Africa are generally founded in system analysis models for water planning and allocation. The Water Resources Yield Model (WRYM) developed in South Africa has so far been the only model applied in official joint water resources studies aimed to form water-sharing agreements. The continuous discussion around the model per
Ewing Sarcoma: Current Management and Future Approaches Through Collaboration.
Ewing sarcoma (ES) is an aggressive sarcoma of bone and soft tissue occurring at any age with a peak incidence in adolescents and young adults. The treatment of ES relies on a multidisciplinary approach, coupling risk-adapted intensive neoadjuvant and adjuvant chemotherapies with surgery and/or radiotherapy for control of the primary site and possible metastatic disease. The optimization of ES mul
Gastroscopy in pediatric surgery: indications, complications, outcomes, and ethical aspects.
Background. The aim of this study was to map gastroscopies performed at a single tertiary pediatric surgery centre to investigate indications, complications, outcomes, and ethical aspects. Material and Methods. A retrospective study of gastroscopies performed during two time periods (2001-2004 and 2011-2014) was conducted. Data regarding indications, outcomes, and complications of pediatric gastro
Use of B-flow ultrasound facilitates visualization of contrast media during hysterosalpingo-contrast sonography (HyCoSy).
To assess if B-flow ultrasound (BF) improves visualization of flow of contrast medium in the Fallopian tubes during hystero-salpingo-contrast sonography (HyCoSy) compared to gray scale (GS) ultrasound.
An international multicentre study on the allergenic activity of air-oxidized R-limonene.
Background. Limonene is a common fragrance terpene that, in its pure form, is not allergenic or is a very weak allergen. However, limonene autoxidizes on air exposure, and the oxidation products can cause contact allergy. Oxidized R-limonene has previously been patch tested in multicentre studies, giving 2-3% positive patch test reactions in consecutive patients. Objectives. To investigate whether
Systemic contact dermatitis in a gold-allergic patient after treatment with an oral homeopathic drug.
Men's and women's perspectives on using a powered mobility device: Benefits and societal challenges.
Abstract Objective: To describe how men and women experience their use of powered wheelchairs (PW) and powered scooters (PS) in everyday occupations, in the home and in society at large. Methods: A qualitative research approach with focus-group methodology was used. Four focus groups were created, with men and women as well as PW and PS users in different groups. Applying a descriptive approach, d
Executive Summary: International Clinical Practice Guidelines for the Treatment of Acute Uncomplicated Cystitis and Pyelonephritis in Women: A 2010 Update by the Infectious Diseases Society of America and the European Society for Microbiology and Infectious Diseases
A Panel of International Experts was convened by the Infectious Diseases Society of America (IDSA) in collaboration with the European Society for Microbiology and Infectious Diseases (ESCMID) to update the 1999 Uncomplicated Urinary Tract Infection Guidelines by the IDSA. Co-sponsoring organizations include the American Congress of Obstetricians and Gynecologists, American Urological Association,
Hydrosilylation of Styrene on Water-Saturated Si(001)-2 x 1 at Room Temperature
The Si(001)-2 x 1 surface saturated by water is characterized by the passivation of nearly all of the dimerized atoms by H/OH terminations, except isolated dangling bonds, whose areal density is in the range of 1.5 +/- 0.2 x 10(-2) defects per Si atom. Therefore the water-saturated Si(001)-2 x 1 surface presents similarities with the defective H-terminated Si(001)2 x I. surface (presence of monohy
Subperiosteal abscesses in acute mastoiditis in 115 Swedish children.
To study the outcome of different surgical methods of treating subperiosteal abscesses resulting from acute mastoiditis.
Neutron Crystallographic Studies Reveal Hydrogen Bond and Water-Mediated Interactions between a Carbohydrate-Binding Module and Its Bound Carbohydrate Ligand.
Carbohydrate-binding modules (CBMs) are key components of many carbohydrate-modifying enzymes. CBMs affect the activity of these enzymes by modulating bonding and catalysis. To further characterize and study CBM-ligand binding interactions, neutron crystallographic studies of an engineered family 4-type CBM in complex with a branched xyloglucan ligand were conducted. The first neutron crystal stru
Adsorption, desorption, and surface-promoted hydrolysis of glucose-1-phosphate in aqueous goethite (alpha-feooh) suspensions
Adsorption, desorption, and precipitation reactions at environmental interfaces govern the fate of phosphorus in terrestrial and aquatic environments. Typically, a substantial part of the total pool of phosphorus consists of organophosphate, and in this study we have focused on the interactions between glucose-I-phosphate (G I P) and goethite (alpha-FeOOH) particles. The adsorption and surface-pro
Effectiveness of beads for tracking small-scale molecular motor dynamics
Investigations into molecular motor dynamics are increasingly focused on small-scale features of the motor's motion. We define performance measures of a common type of single-molecule motility assay, the bead assay, for its ability to detect such features. Using numerical models, we explore the dependence of assay performance on a number of experimentally controllable parameters, including bead si
Measurements of occupancy levels in multi-family dwellings-Application to demand controlled ventilation
The occupancy level of dwellings is an important parameter to know to determine the energy efficiency, energy use and indoor air quality, especially in low-energy buildings where the user-related energy uses, such as household electricity and domestic hot water heating, are significant parts of the energy balance in a building. For residential buildings, there is a lack of occupancy level data, wh
