Multilayered Magnetic Nanoparticles as a Support in Solid-Phase Peptide Synthesis

The synthesis of multilayered magnetic nanoparticles (MNPs) for use as a support in solid-phase peptide synthesis (SPPS) is described. Silanization of magnetite (Fe3O4) nanoparticles with 3-(trimethoxysilyl)propyl methacrylate introduced polymerizable groups on the surface. Polymerization with allylamine, trimethylolpropane trimethacrylate, and trimethylolpropane ethoxylate (14/3 EO/OH) triacrylat

Personal factors in systemic sclerosis and their coverage by patient-reported outcome measures

Background. Systemic sclerosis (SSc) is an autoimmune disease where thickening of the skin can lead to reduced body function and limitations in activities. Severe forms can also affect and seriously damage inner organs. Patient-centred rehabilitation emphasises considerations of patients' background, experience and behavior which highlights the need to know if patient-reported outcome measures (PR

The ubiquitin proteasome system in neurodegenerative diseases: Sometimes the chicken, sometimes the egg

The ubiquitin-proteasome system targets numerous cellular proteins for degradation. In addition, modifications by ubiquitin-like proteins as well as proteins containing ubiquitin-interacting and -associated motifs modulate many others. This tightly controlled process involves multiple specific and general enzymes of the system as well as many modifying and ancillary proteins. Thus, it is not surpr

Videomanometric analysis of supraglottic swallow, effortful swallow, and chin tuck in patients with pharyngeal dysfunction

Simultaneous videoradiography and solid-state manometry (videomanometry) was performed in 8 patients (4 women, 4 men; age range = 46-81 years, mean age = 70 years) with pharyngeal dysfunction. Five patients had severe pharyngeal dysfunction with frequent misdirected swallows. Three patients had moderate pharyngeal dysfunction with delayed initiation of pharyngeal swallow. Three different swallowin

Disturbances of autonomic nervous function in primary Sjogren's syndrome

Autonomic nervous function was evaluated by deep breathing [expiration/inspiration (E/I) ratio] and tilt table tests [acceleration (AI) and brake indices (BI)] in 19 patients with primary Sjogren's syndrome (pSS) and in 56 age matched controls. The E/I-ratio and systolic blood pressure (at rest, 1, and 8 min after tilt) were found to be significantly reduced (p < 0.001, p < 0.05, p < 0.01, p < 0.0

Four-Point Preprandial Self-Monitoring of Blood Glucose for the Assessment of Glycemic Control and Variability in Patients with Type 2 Diabetes Treated with Insulin and Vildagliptin.

The study explored the utility of four-point preprandial glucose self-monitoring to calculate several indices of glycemic control and variability in a study adding the DPP-4 inhibitor vildagliptin to ongoing insulin therapy. This analysis utilized data from a double-blind, randomized, placebo-controlled crossover study in 29 patients with type 2 diabetes treated with vildagliptin or placebo on top

Staging Presymptomatic Type 1 Diabetes: A Scientific Statement of JDRF, the Endocrine Society, and the American Diabetes Association.

Insights from prospective, longitudinal studies of individuals at risk for developing type 1 diabetes have demonstrated that the disease is a continuum that progresses sequentially at variable but predictable rates through distinct identifiable stages prior to the onset of symptoms. Stage 1 is defined as the presence of β-cell autoimmunity as evidenced by the presence of two or more islet autoanti

Effect of geometry optimisations on QM-cluster and QM/MM studies of reaction energies in proteins

We have examined the effect of geometry optimisation on energies calculated with the quantum-mechanical (QM) cluster, the combined QM and molecular-mechanics (QM/MM), the big-QM approaches (very large single-point QM calculations taken from QM/MM-optimised structures, including all atoms within 4.5 Å of the minimal active site, all buried charged groups in the protein, and truncations moved at lea

Monte Carlo simulations of Donnan equilibrium in cartilage

(23) Na magnetic resonance imaging and the delayed gadolinium-enhanced magnetic resonance imaging methods to investigate cartilage can be used to determine the fixed charge density of cartilage. The methods give results that differ by a factor of 2. In this study, we use Monte Carlo simulations on a model system of cartilage and find that the difference originates from the Coulombic intermolecular

The dawn of terrestrial ecosystems on Baltica: First report on land plant remains and arthropod coprolites from the Upper Silurian of Gotland, Sweden

Abstract in UndeterminedSporangia, with their in situ cryptospores, spore masses, and a possible axis were identified in marginal marine Ludlovian deposits from Gotland. Sweden by means of light- and scanning electron microscopy.The sporangia identified are elongate, with fragments of the sporangia covering preserved, and contain well-preserved in situ embryophyte cryptospores identified as Laevol

Partial volume correction of brain perfusion estimates using the inherent signal data of time-resolved arterial spin labeling.

Quantitative perfusion MRI based on arterial spin labeling (ASL) is hampered by partial volume effects (PVEs), arising due to voxel signal cross-contamination between different compartments. To address this issue, several partial volume correction (PVC) methods have been presented. Most previous methods rely on segmentation of a high-resolution T1 -weighted morphological image volume that is coreg

Tracking Restorative Components: Patterns in Eye Movements as a Consequence of a Restorative Rating Task

Eye tracking was used to investigate the task of assessing how likely it is that one would be able to rest and recover in small urban spaces and how it affects the view pattern. We assess which environmental components, for example, flowers and trees, participants look at when evaluating restoration likelihood. Further, we compare number of fixations in restorative and non-restorative park photos.

The influences of the transfer method and particle surface chemistry on the dispersion of nanoparticles in nanocomposites

The synthesis via in situ polymerization and characterization of nanocomposites (NCs) made from silica (SiO2) nanoparticles in a methyl methacrylate (MMA) monomer matrix is reported. We first investigate the transfer of well-defined spherical silica nanoparticles (NPs) (average radius R = 24.2 +/- 3.2 nm) into the monomer solvent. We study the influence of two transfer methods and different surfac

Control and understanding of kink formation in InAs-InP heterostructure nanowires.

Nanowire heterostructures are of special interest for band structure engineering due to an expanded range of defect-free material combinations. However, the higher degree of freedom in nanowire heterostructure growth comes at the expense of challenges related to nanowire-seed particle interactions, such as undesired composition, grading and kink formation. To better understand the mechanisms of ki

Genome-wide Association Study Identifies Five Susceptibility Loci for Follicular Lymphoma outside the HLA Region.

Genome-wide association studies (GWASs) of follicular lymphoma (FL) have previously identified human leukocyte antigen (HLA) gene variants. To identify additional FL susceptibility loci, we conducted a large-scale two-stage GWAS in 4,523 case subjects and 13,344 control subjects of European ancestry. Five non-HLA loci were associated with FL risk: 11q23.3 (rs4938573, p = 5.79 × 10(-20)) near CXCR5

Long-term effect of apatite on ectomycorrhizal growth and community structure.

Ectomycorrhizal (ECM) fungi are efficient at taking up phosphorus (P) from mineral sources, such as apatite, which are not easily available to the host trees. Since ECM fungal species differ in P uptake rates, it can be expected that the composition of the ECM fungal community will change upon exposure to apatite, provided that the P transfer is rewarded by more carbon being transferred to the fun

Children's affective experience of every-day travel

This study aims to evaluate if children's affective experience of every-day travel varies depending on travel mode and destination of travel. More specifically, what are children's reported valence (unpleasantness-pleasantness) and activation (deactivation-activation) while travelling to different destinations and does this experience have spill-over effects on how they perceive activities at the
