Susceptibility-weighted imaging (SWI) has recently attracted attention for its ability to investigate acute stroke pathophysiology. SWI detects an increased ratio of deoxyhemoglobin to oxyhemoglobin in cerebral venous compartments, which can illustrate cerebral misery perfusion with a compensatory increase of oxygen extraction fraction in the hypoperfused brain. In this study we make the first cas
The soluble proteins and protein aggregates in Belinda oats were characterized using asymmetric flow field-flow fractionation (AF4) coupled with online UV-vis spectroscopy and multiangle light-scattering detection (MALS). Fractions from the AF4 separation were collected and further characterized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The AF4 fractogram of the oat
It is shown how results on Carleson embeddings induced by the Laplace transform can be used to derive new and more general results concerning the weighted (infinite-time) admissibility of control and observation operators for linear semigroup systems with q-Riesz bases of eigenvectors. As an example, the heat equation is considered. Next, a new Carleson embedding result is proved, which gives furt
In recent years, exterior thermal insulation systems became more and more important leading to an increasing amount of houses equipped with biocide-containing organic façade coatings or fungicide treated wood. It is known that these biocides, e.g. terbutryn, carbendazim, and diuron, as well as wood preservatives as propiconazole, leach out of the material through contact with wind driven rain. Hen
This work addresses structural and nonequilibrium effects of the interactions between well-defined cationic poly(amidoamine) PAMAM dendrimers of generations 4 and 8 and the anionic surfactant sodium dodecyl sulfate (SDS) at the hydrophilic silica-water interface. Neutron reflectometry and quartz crystal microbalance with dissipation monitoring were used to reveal the adsorption from premixed dendr
Babesiosis is an emerging tick-transmitted zoonosis in large parts of the world. In Sweden, the occurrence and diversity of Babesia species is largely unknown. In order to estimate the exposure to Babesia from infected ticks, we collected questing Ixodes ricinus from several sites across southern Sweden during two consecutive field seasons and investigated the occurrence of Babesia species. We rep
Gated transport measurements are the backbone of electrical characterization of nanoscale electronic devices. Scanning gate microscopy (SGM) is one such gating technique that adds crucial spatial information, accessing the localized properties of semiconductor devices. Nanowires represent a central device concept due to the potential to combine very different materials. However, SGM on semiconduct
The aim of this study was to determine whether total fertilization failure in human IVF can be partially explained by alterations in the gene that codes for protein C inhibitor. Forty-six men had IVF total fertilization failure and 51 controls with normal fertilization were screened for mutations in the protein C inhibitor gene by direct sequencing. The main finding was that in men involved in tot
The intestine presents a huge surface area to the outside environment, a property that is of critical importance for its key functions in nutrient digestion, absorption, and waste disposal. As such, the intestine is constantly exposed to dietary and microbial-derived foreign antigens, to which immune cells within the mucosa must suitably respond to maintain intestinal integrity, while also providi
Objective To determine the association between characteristics at diagnosis and the time to first relapse in a large cohort of patients with antineutrophil cytoplasmic antibodyassociated vasculitis (AAV). Methods. We studied long-term followup data from 4 clinical trials that included newly diagnosed patients with a broad spectrum of AAV severity and manifestations. Patient and disease characteris
The electroencephalography (EEG) signal has a high complexity, and the process of extracting clinically relevant features is achieved by visual analysis of the recordings. The interobserver agreement in EEG interpretation is only moderate. This is partly due to the method of reporting the findings in free-text format. The purpose of our endeavor was to create a computer-based system for EEG assess
Abnormal aggregation of SNCA/-synuclein plays a crucial role in Parkinson disease (PD) pathogenesis. SNCA levels determine its toxicity, and its accumulation, even to a small extent, may be a risk factor for neurodegeneration. One of the main pathways for SNCA degradation is chaperone-mediated autophagy (CMA), a selective form of autophagy, while aberrant SNCA may act as a CMA inhibitor. In the cu
Rationale: Acute lung injury (ALI) causes high mortality, but its molecular mechanisms and therapeutic options remain ill-defined. Gram-negative bacterial infections are the main cause of ALI, leading to lung neutrophil infiltration, permeability increases, deterioration of gas exchange, and lung damage. Platelets are activated during ALI, but insights into their mechanistic contribution to neutro
Acute lung injury is caused by many factors including acute pancreatitis. There is no specific therapy directed at underlying pathophysiological mechanisms for acute lung injury. Transforming growth factor- β (TGF- β ) is involved in the resolution of lung injury in later phases of the disease. Some evidence exists demonstrating that TGF- β not only is involved in the late stages, but also contrib
Response times to risky events have been seen to increase with the use of adaptive cruise control (ACC). It has been unclear whether driver experience with ACC mediates this increase. We compare driving in a cut-in event in a simulator both with and without system support, studying ACC as well as ACC with automatic steering. 31 participants were tested in a repeated-measures design, 10 novices and
The purpose of this study was to determine whether administration of postoperative antibiotics affects the incidence of complications after primary cleft palate repair in a developing area.
IgG antibodies have one conserved N-glycosylation site at Asn 297 in each of their constant heavy chain regions. These Fc glycans influence the overall structure and pro- or anti-inflammatory effector functions of IgG antibodies. The biantennary core glycan structure, consisting of four N-acetyl-glucosamine (GlcNAc) and three mannose residues, can be further decorated with fucose, a bisecting GlcN
The electrochemical characterization of a class II cellobiose dehydrogenase (CDH), from the ascomycete fungus Neurospora crassa. adsorbed on graphite (G), was performed in regard to direct (DET) and mediated electron transfer (MET). The effects of the applied potential, mediator (1,4 benzoquinone) concentration and flow carrier pH on the amperometric response of the G/CDH modified electrodes were
Objectives To prospectively assess the diagnostic performance of simple ultrasound rules to predict benignity/malignancy in an adnexal mass and to test the performance of the risk of malignancy index, two logistic regression models, and subjective assessment of ultrasonic findings by an experienced ultrasound examiner in adnexal masses for which the simple rules yield an inconclusive result. Desig
BACKGROUND: The possibility of an association of Graves' disease (GD) with subsequent cancers raised by certain studies. METHODS: Using a database on 18 156 hospitalised GD patients, subsequent cancers were ascertained. RESULTS: Increased risks of thyroid and parathyroid tumours were limited to the early follow-up period, which is probably a surveillance bias. Cancer sites with observed excess inc
