Background: Cataracts are the leading cause of reversible blindness globally, disproportionately affecting populations in low- and middle-income countries. In Ethiopia, cataracts remain a significant public health concern. Despite the effectiveness of cataract surgery in restoring vision, information on recovery time and its predictors remain limited. The aim of this study was to assess time to re
There is an urgent need for accurate and validated methods to measure plasma phosphorylated tau (p-Tau) biomarkers in Alzheimer’s disease (AD). In this study, we compared the performance of new commercially available plasma p-Tau217 assay developed by ALZpath to other established p-Tau assays in an autopsy-confirmed sample. We included 72 participants from the Arizona Study of Aging and Neurodegen
Before performing 177Lu-DOTATATE therapy for neuroendocrine tumors, somatostatin receptor (SSTR) PET imaging is currently used to confirm sufficient tumor SSTR expression, but it also has potential to be used to personalize treatment by predicting absorbed doses to critical organs. This study aims to validate the predictive capability of SSTR PET in anticipating renal absorbed dose in the first cy
Evidence from neuropathological cohorts indicates that a CSF α-synuclein (α-syn) seed amplification assay (SAA) might provide quantitative kinetic parameters correlating with α-syn pathology burden in patients with Lewy body disease (LBD). Studies are needed to assess their longitudinal trend during the presymptomatic and clinical disease phases and their correlation with measures of disease progr
In spite of the efforts made for canopy water content (CWC) mapping in the community, including vegetation water proxy from microwave-based vegetation optical depth (VOD) as well as optical-based indices, there is still no operational CWC product from optical satellites up to now. To fill this gap, this study proposes a unified algorithm for CWC mapping at both decametric and coarse spatial resolu
Background Pulmonary nodules (PNs) are clinically challenging because differentiation between benign and malignant PNs is not possible at CT detection; recurring CT examinations and invasive procedures are often required in PN follow-up. Purpose To investigate PN prevalence in a middle-aged population and the risk factors associated with these nodules. Materials and Methods In this secondary analy
Popular Abstract in Swedish Bröstcancer är den vanligaste dödsorsaken bland cancersjuka kvinnor. Därför rekommenderas regelbundna mammografiska hälsokontroller för tidig diagnostik och snar behandling för att förbättra prognosen. I Sverige rekommenderas kontroller för kvinnor mellan 40-74 år. Mammografiska hälsokontroller medför dock även risker, såsom till exempel behov av kompletterande bröstundOne side-effect of breast cancer (BC) screening is a false-positive mammogram among healthy women. That is, finding(s) on a screening mammogram that lead to additional breast examinations but where the woman is eventually considered free from BC. There is evidence of short-term psychosocial consequences of false-positive BC screening. Regarding long-term consequences, research findings are inconsi
The presented thesis work is concerned with the study of molecular dynamics using liquid nuclear magnetic resonance (NMR) spectroscopy. Spin relaxation dispersion experiments in the rotating frame (R1ρ) are employed to provide a detailed, atomic-resolution view of protein dynamics. Comprehensive investigations of 15N backbone and 13C methyl side-chain confo
Background There is currently no standardized process for long-term follow-up care. As a result, management of post-stroke care varies greatly, and the needs of stroke survivors are not fully addressed. The Post Stroke Checklist was developed by the Global Stroke Community Advisory Panel as a means of standardizing long-term stroke care. Since its development, the Post Stroke Checklist has gained
Mineralogical and geochemical studies of the non-marine Permian–Triassic (P–Tr) boundary across two stratigraphically wellconstrained sections (Commando Drift Dam and Wapadsberg, Eastern Cape Province) in the southern Karoo Basin, South Africa, have been undertaken to provide further input on the cause of this mass extinction event, and so has a sedimentological and geochemical evaluation of a thi
Subsolidus phase relations have been determined for the BaO:TiO2:Ta2O5 system by X-ray diffraction analysis of ~100 specimens prepared in air at temperatures near but below the solidus (1275 °C to 1500 °C). For the BaO:Ta2O5 subsystem, the formation of all three polymorphs of BaTa2O6 (orthorhombic, tetragonal, and hexagonal) was confirmed. The present study found no stable phases forming between B
Popular Abstract in Swedish Transplantation av dopaminceller från mänskliga foster kan förbättra funktionen hos patienter med Parkinsons sjukdom (Lindvall 1997, Björklund 2000a). Man har kunnat visa att transplantaten har återställt dopaminproduktionen i striatum till normala nivåer i flera fall, och till 70-80% av normalt i majoriteten av de patienter som transplanterats i Lund. Transplantaten haTransplantation of embryonic human neural tissue can restore function in patients with Parkinson’s disease, but there is a severe shortage of donor tissue which limits the applicability of the technique. Embryonic neural tissue from other species, xenogeneic tissue, would provide a readily accessible donor tissue with the potential to help patients if the immunological reactions in the host could
High northern latitudes are of special importance for the global carbon budget as they store large amounts of organic matter in the soil and are expected to be the most strongly affected by climate change. Here we investigate carbon exchange in the subarctic mountain birch forest growing on the limit where tree growth is possible. The study sites are located close to the Abisko village in norther
Popular Abstract in English There is a natural tendency to take advantage of the most convenient energy source available. In this usage, convenient may mean most abundant, easiest to harvest or simplest to handle. Convenient will also correspond to cheapest in many instances. However, some consider it a responsibility to think of the long term costs of the energy we use. No form of energy is free The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. The burner was operated using methane and three s
The spectrum and energy levels C IV and the 3l4l' system of the Mg-like ions in the iron group elements has been investigated. This has led to several hundred identified transitions, many of them previously unknown. Using the Charge Exchange diagnostic system at JET, ion temperatures, rotation velocities and densities have been derived from visible spectroscopic measurements on fully ionised light
OBJECTIVE: To study the pharmacodynamics of amoxicillin/clavulanic acid against different strains of Haemophilus influenzae in an in vitro kinetic model. The concentrations used corresponded to human serum levels obtained after 875 mg amoxicillin/clavulanic acid given b.i.d., 500/125 mg amoxicillin/clavulanic acid given t.i.d. and those obtained with a pharmacokinetically enhanced formulation cont
Background and objective: Human studies of arterio-venous (AV) differences in drug concentrations and the consequences for pharmacokinetic modelling and concentration-effect relationships are very limited. We therefore investigated the intravenous and intra-arterial concentrations of alcohol (ethanol) during the absorption, distribution and elimination stages of alcohol metabolism in healthy men.
