Objective. To study the effect of valgus malalignment on knee osteoarthritis (OA) incidence and progression. Methods. We measured the mechanical axis from long limb radiographs from the Multicenter Osteoarthritis Study (MOST) and the Osteoarthritis Initiative (OAI) to define limbs with valgus malalignment (mechanical axis of >= 1.1 degrees valgus) and examined the effect of valgus alignment versus
Most macroeconomic and financial panel variables are trending. However, because of the well-known power problem in the presence of incidental trends, many researchers gamble that their unit root test regressions can be ran without such trends, thereby running the risk of obtaining spurious results. This article takes one of the most general and popular panel unit root tests, known as PANIC, and sh
Cellobiose dehydrogenase (CDH) has recently become a redox enzyme at focus in bioelectrochemistry especially for the construction of sugar biosensors and biofuel cell anodes. The present study shows that an increase in the CaCl2 concentration to up to 100 mM led to an increase in the maximal catalytic current generated by two different Ascomycete and one Basidiomycete CDH immobilised on a spectros
We show for the first time that 1,2-dilauroyl-sn-glycero-3-phosphatidyladenosine nucleolipid surface complexes with cationic poly(amidoamine) dendrimers can be used to selectively bind DNA including oligonucleotides. This molecular recognition has high potential for applications involving biomedical and bioanalytic devices as well as drug delivery systems based on nucleic acids.
Autism spectrum disorders (ASD) are a heterogeneous group of neurodevelopmental disorders with a complex inheritance pattern. While many rare variants in synaptic proteins have been identified in patients with ASD, little is known about their effects at the synapse and their interactions with other genetic variations. Here, following the discovery of two de novo SHANK2 deletions by the Autism Geno
Human fetal midbrain tissue grafting has provided proof-of-concept for dopamine cell replacement therapy (CRT) in Parkinson's disease (PD). However, limited tissue availability has hindered the development and widespread use of this experimental therapy. Here we present a method for generating large numbers of midbrain dopaminergic (DA) neurons based on expanding and differentiating neural stem/pr
A new acylated neohesperoside derivative, 1-octyl-4'-isovaleroyl-neohesperoside (1), was isolated from Geranium purpureum Vill. (Geraniaceae) together with the known compounds quercetin-3-rutinoside and gallic acid. The identification of the isolated compounds was carried out by spectroscopic analysis including 1D- and 2D- NMR (H-1, C-13, COSY, HSQC and HMBC) spectroscopy and ESI-TOF-MS.
We present a light-storage experiment in a praseodymium-doped crystal where the light is mapped onto an inhomogeneously broadened optical transition shaped into an atomic frequency comb. After absorption of the light, the optical excitation is converted into a spin-wave excitation by a control pulse. A second control pulse reads the memory (on-demand) by reconverting the spin-wave excitation to an
Objectives:Body size is postulated to modulate type 1 diabetes as either a trigger of islet autoimmunity or an accelerator to clinical onset after seroconversion. As overweight and obesity continue to rise among children, the aim of this study was to determine whether human leukocyte antigen DQ (HLA-DQ) genotypes may be related to body size among children genetically at risk for type 1 diabetes.Me
Abstract Dercum's disease is characterised by pronounced pain in the adipose tissue and a number of associated symptoms and is, in most patients, accompanied by obesity. Postoperative sensory change after liposuction is a well-known side effect, and probably caused by mechanical trauma to the nerves. The aim of this investigation was to find out whether the thermal and sensory sensation changed af
Plasma low-density lipoprotein cholesterol (LDL-C) has been associated with aortic stenosis in observational studies; however, randomized trials with cholesterol-lowering therapies in individuals with established valve disease have failed to demonstrate reduced disease progression.
To study the outcome of different surgical methods of treating subperiosteal abscesses resulting from acute mastoiditis.
We report calculations of Born-Oppenheimer potential energy curves of the chromium-rubidium heteronuclear molecule ((CrRb)-Cr-52-Rb-87), and the long-range dispersion coefficient for the interaction between ground state Cr and Rb atoms. Our calculated van der Waals coefficient (C-6 = 1770 a.u.) has an expected error of 3%. The ground state (6)Sigma(+) molecule at its equilibrium separation has a p
Objective: The objective of the present study was to evaluate the pharmacokinetics and the clearance pathways of rFVIIa after intravenous administration to haemophilia patients. Methods: Ten severe haemophilia patients were included in the study; all patients were intravenously administered a clinical relevant dose of 90 μg/kg (1.8 nmol/kg) rFVIIa. Blood samples were collected consecutively to des
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 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
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
PURPOSE OF REVIEW: A time-related negative trend in male reproductive function has been suggested. It has been hypothesized that this is due to exposure to chemicals interfering with the action of sex hormones. Also a negative effect of phytoestrogens on male fertility has been postulated. This review aimed to review the epidemiological evidence of deteriorating male reproductive function and summ
