Background: Accumulation of activated neutrophilic leucocytes is known to increase uptake of 18F-fluorodeoxyglucose (18F-FDG) into lung tissue. Available evidence suggests that smokers and subjects with chronic obstructive pulmonary disease (COPD) have neutrophilic inflammation in peripheral airways. The aim of this study was to examine whether current smokers have higher lung tissue uptake of 18F
The burden of atopic dermatitis (AD) was assessed. A population-based, cross-sectional questionnaire study was performed among 34,313 Swedish adults in 2017. The prevalence of AD was 14%. Adults with mild AD had an increased relative risk ratio (RRR) of severe depression (aRRR 1.78, 95% confidence interval (95% CI) 1.50–2.12) and anxiety (aRRR 1.97, 95% CI 1.69–2.30), which was higher for severe A
The aim of this study is to examine the reception of Origen of Alexandria (185-253/54) in the eschatological thought ofJerome of Stridon (347-419/20). Jerome, who was a Christian ascetic writer and a biblical commentator, relied heavily on Origen’s works during the first part of his career. Due to the Origenist controversy, which took place in the 390s and was initiated by Bishop Epiphanius of Sal
Objective: To develop and perform ex vivo 3D imaging of meniscus posterior horn microstructure using micro-computed tomography (μCT), and to compare specimens from healthy references against end-stage osteoarthritis (OA) using conventional section-based histology and qualitative μCT. Design: We retrieved human medial and lateral menisci from 10 deceased donors without knee OA (healthy references)
We have used a reverse transcriptase-polymerase chain reaction (RT-PCR) protocol to examine the expression of cytokines in the pancreases and islets of patients with type I diabetes. We detect a significant increase in the level of expression of interferon (IFN)-α in the pancreases of the diabetic patients as compared with the control pancreases. In contrast, IFN-β was detected at comparable level
The GABA synthesizing enzyme GAD is a prominent islet cell autoantigen in type I diabetes. The two forms of GAD (GAD64 and GAD67) are encoded by different genes in both rats and humans. By in situ hybridization analysis of rat and human pancreases, expression of both genes was detected in rat islets, whereas only GAD64 mRNA was detected in human islets, Immunocytochemical analysis of rat and human
The BB rat is among the best models of insulin−dependent diabetes mellitus — with onset and pathogenesis closely resembling the human disease. One unusual feature is a severe T−cell lymphopenia, which appears to be inherited as a recessive trait controlled by a single gene, Lyp. Based on genetic analysis of several crosses, we show that development of diabetes involves at least three genes: Lyp, w
Daily injections of high dose human recombinant interleukin-1β (IL-1β) accelerated the onset of both insulin-dependent diabetes mellitus and lymphocytic thyroiditis in genetically prone BB rats. In diabetes-resistant BB rats, high dose IL-1β failed to induce diabetes. Additionally, the presence of neutralizing IL-1β antibodies in these rats strongly correlated with inhibition of lymphocytic thyroi
Insulin autoantibodies (IAAs) occur in newly diagnosed human insulin-dependent diabetes mellitus (IDDM) patients, but their presence in BB rats is controversial, possibly due to assay differences or variability in the animals studied. To resolve this controversy, IAAs were measured in well-characterized inbred BB rats both in radioligand assays with 125I-labeled rat insulin I or II, respectively,
The jet radial structure and particle transverse momentum (pT) composition within jets are presented in centrality-selected Pb–Pb collisions at sNN=2.76 TeV. Track-based jets, which are also called charged jets, were reconstructed with a resolution parameter of R=0.3 at midrapidity |ηch jet|<0.6 for transverse momenta pT,ch jet=30–120 GeV/c. Jet–hadron correlations in relative azimuth and pseudora
The uptake of chloromercuribenzene-p-sulphonic acid (CMBS) was studied in microdissected pancreatic islets of ob/ob-mice. After rapid initial binding, the uptake increased linearly with time, suggesting that CMBS diffused into the plasma membrane. The binding of CMBS was rapidly reversed on exposure to l-cysteine. Whereas glibenclamide had no effect, glucose and 4-acetamido-4′-isothiocyanostilbene
The insulin-releasing ability and uptake characteristics of non-metabolizable, transport-specific amino acids were studied in an in vitro system, using microdissected pancreatic islets with more than 90% β-cells. Among the four stereoisomers of 2-aminobicyclo(2,2,1)heptane-2-carboxylic acid (BCH), only the b(-) form stimulated insulin release. This isomer is known as a specific substrate for trans
Germ-line mutations in BRCA2 have been linked to early-onset familial breast cancer. BRCA2 is known to play a key role in repairing double-strand breaks. Here,we describe the involvement of BRCA2 in O6-alkylguanine DNA alkyltransferase (AGT)-mediated repair of O6-methylguanine adducts. We show that BRCA2 physically associates and undergoes repair-mediated degradation with AGT. In contrast, BRCA2 w
The creatine kinase (CK) isoenzyme system is essential for motility in rooster and sea urchin sperm. In the present study, biochemical characterization as well as immunofluorescence and confocal laser microscopy with highly specific antibodies against various chicken CK isoenzymes revealed that cytosolic brain-type CK isoenzyme (B-CK) is the only CK isoenzyme in rooster seminal plasma, while three
Sarcomeric mitochondrial creatine kinase (Mi(b)-CK) of chicken was expressed in Escherichia coli as a soluble enzyme by using an inducible phage-T7 promoter. Up to one third of the protein in E. coli extracts consisted of soluble recombinant Mi(b)-CK in an enzymically active form. Approx. 20 mg of nearly-homogenous Mi(b)-CK was isolated in a two-step isolation procedure starting with 1 litre of is
The resistance of mice to asphyxiation in pure nitrogen at 5 ata, after equilibration with a high pressure atmosphere (4.2 % O2 in N2, 5 ata; “normal” Po2) producing a nitrogen anaesthesia, has been compared to the resistance of mice exposed to pure nitrogen at 1 ata after atmospheric air breathing. The anoxic resistance was increased by 58 % by the nitrogen anaesthesia.
Resistivity data constitute the largest part of the available information to assess the hydrogeological characteristics of the aquifer system near Oruro, in the central part of the Bolivian Altiplano. Two aquifers are part of this system; top unconsolidated sediments storing fresh water in their granular voids, overlying fractured hard rock formations where saline water was detected in connection
Parkinson’s disease (PD) affects 2–3% of the population over the age of 65 with loss of dopaminergic neurons in the substantia nigra impacting the functioning of basal ganglia-thalamocortical circuits. The precise role played by the thalamus is unknown, despite its critical role in the functioning of the cerebral cortex, and the abnormal neuronal activity of the structure in PD. Our objective was
Inflammation is a vital response and necessary for maintaining homeostasis. Inflammation protects against tissue damage and pathogens-but is also one of the main driving forces of the atherosclerotic plaque progression. How and why the inflammatory response is initiated in the atherosclerotic disease is not fully known, but evidence suggests modified lipids as potential antigens activating the imm
