We reviewed a 7-year series of brain MRI examinations to determine the frequency and clinical significance of superficial siderosis of the central nervous system (SS). SS was defined by widespread bilateral signal loss at the surfaces of the cerebral or cerebellar hemispheres, the brain stem and the spinal cord on T2-weighted images. Clinical data comprised(More)
12-O-Tetradecanoylphorbol-13-acetate (TPA), the prototype polyfunctional diterpene ester tumor promoter of two-step carcinogenesis in mouse skin, induced differentiation of human promyelocytic leukemia cells (HL-60) in culture. Differentiation of HL-60 cells was characterized by increased phagocytosis, increased lysozyme activity (EC 3.2.1.17) in the growth(More)
A modern diatom-pH calibration data-set consisting of surface-sediment diatom assemblages from 118 lakes and 530 taxa is presented. The AL:PE data-set is from high-altitude or high-latitude lakes in the Alps, Norway, Svalbard, Kola Peninsula, UK, Slovenia, Slovakia, Poland, Portugal, and Spain (pH range = 4.5–8.0; DOC range = 0.2–3.2 mg l). In addition, 92(More)
We present constraints on the mean matter density, Ωm, dark energy density, ΩDE, and the dark energy equation of state parameter, w, using Chandra measurements of the X-ray gas mass fraction (fgas) in 42 hot (kT > 5keV), X-ray luminous, dynamically relaxed galaxy clusters spanning the redshift range 0.05 < z < 1.1. Using only the fgas data for the six(More)
Searches for the direct electroweak production of supersymmetric charginos, neutralinos, and sleptons in a variety of signatureswith leptons andW,Z, andHiggs bosons are presented. Results are based on a sample of protonproton collision data collected at center-of-mass energy √ s = 8TeV with the CMS detector in 2012, corresponding to an integrated luminosity(More)
The Mini Mental State Examination (MMSE) and the Mattis Dementia Rating Scale (MDRS) are among the most commonly used screening tests for dementia. The goals of our study were, firstly, to identify sociode-mographic factors which may explain the variance of test results in a community sample and, secondly, to investigate the interrelationship of these two(More)
A measurement of the cross section for the production of top quark–antiquark pairs (tt) in associationwith a vector boson V (W or Z) in proton-proton collisions at √ s = 8TeV is presented. The results are based on a dataset corresponding to an integrated luminosity of 19.5 fb−1 recorded with the CMS detector at the LHC. The measurement is performed in three(More)
In euthyroidism the circadian rhythm and pulsatility of TSH is well known. With regard to hyperthyroidism only very preliminary data were described. In this tudy we investigated the secretion pattern of the pituitary-thyroid axis hormones during 24 h in latent and overt hyperthyroidism and in euthyroidism with regard to common and different properties.(More)
This review describes differing profiles of vascular risk factors in different types of dementia. Although vascular risk factors are related to various types of strokes, their independent effect on the occurrence of poststroke dementia appears to be small. Various risk factors have been identified for microangiopathy-related cerebral abnormalities, such as(More)
Subclinical thyroid disorders have received increasing attention in recent years due to refined laboratory methods and a stronger emphasis on the role of preventive medicine. We performed a screening for thyroid-stimulating hormone (TSH) on 6884 persons in a working population. In cases in which TSH was not within the normal range we also measured the(More)
