The clinical picture with its pathological correlate was analysed in 16 patients fulfilling consensus criteria for dementia with Lewy bodies (DLB). The cases were part of a larger cohort (n = 200) of patients within a prospective longitudinal study of dementing disorders. Six cases exhibited not only Lewy bodies (LBs) but also other brain pathologies such as Alzheimer changes, multiple infarcts or
Capsule endoscopy (CE) has greatly facilitated the diagnosis of small-bowel lesions in patients with obscure gastrointestinal bleeding [1]. It was recently reported by Hollerbach et al. [2] that endoscopically assisted video capsule endoscopy facilitates the investigation of the small bowel in patients with functional gastric outlet obstruction. Swallowing difficulties, which are not uncommon in e
When mice are injected with dexamethasone, cortical thymocytes are deleted through programmed cell death (PCD). We have used this in vivo model system to investigate the kinetics of PCD and cell proliferation in relation to polyamine metabolism for 16 h after injection of dexamethasone. As a marker for PCD, we used the appearance of a sub-G(1)peak in the DNA histogram. When a sub-G(1)peak appeared
The influence of incubation time and Fenton reagent concentrations was investigated on the oxidation of 2'-deoxyguanosine. The compounds identified and quantified, through use of an LC-MS/MS system, were 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) and 8,5'- cyclo-2'-deoxyguanosine (8,5'cyclodG) and the secondary oxidation products guanidinohydantoin and dehydro-guanidinohydantoin. 8-oxodG and 8,
Intracapsular hip pressure was measured before surgery in 17 patients (18 hips) with coxarthrosis. The results were correlated to pain as registered on a visual analog scale. With the hip in extension, the pressure was 49.5 mmHg (SD, 40.2); in 45 degrees of flexion, it was 21.3 mmHg (SD, 14.6); in extension and inward rotation, it was 105.7 mmHg (SD, 76.0); and in extension and outward rotation, i
We argue that critical management studies (CMS) should be conceptualized as a profoundly performative project. The central task of CMS should be to actively and pragmatically intervene in specific debates about management and encourage progressive forms of management. This involves CMS becoming affirmative, caring, pragmatic, potential focused, and normative. To do this, we suggest a range of tact
To investigate the role of apoM in high density lipoprotein (HDL) metabolism and atherogenesis, we generated human apoM transgenic (apoM-Tg) and apoM-deficient ( apoM(-/-)) mice. Plasma apoM was predominantly associated with 10-12-nm alpha-migrating HDL particles. Human apoM overexpression (11-fold) increased plasma cholesterol concentration by 13-22%, whereas apoM deficiency decreased it by 17-21
The objective of this study was to isolate fibrotic cells from human lung biopsies taken from different central pulmonary locations. A comparison was made of cell morphology, proteoglycan- and protein-expression in mesenchymal cell cultures obtained from human bronchial biopsies from patients with asthmatic-like disorders. We isolated viable cells from 10 out of the 12 biopsies. The fibroblast-lik
The picture superiority effect, i.e. better memory for pictures than for corresponding words, has been variously ascribed to a conceptual or a perceptual processing advantage. The present study aimed to disentangle perceptual and conceptual contributions. Pictures and words were tested for recognition in both their original formats and translated into participants´ second language. Multinomial Pro
The copolymer of N-isopropylacrylamide and 3-(acrylamido)phenylboronic acid (82:18, (M) over bar (n)=47000 g. mol(-1)) was prepared by free radical polymerization. The copolymer showed typical thermal precipitation behavior in aqueous solutions, its precipitation temperature (T-P) being increased from 23 to 32degreesC by increasing the pH from 6.5 to 9.7, because of ionization of the phenylboronat
The process simulator ASPEN PLUS was used for simulation of an ethanol production process based on enzymatic hydrolysis of lignocellulosic materials. The effect of water recycling, necessary to reduce the amount of waste water and to increase the ethanol concentration in the feed to the distillation, was investigated. For a process based on 20 t/h raw material, the amount of waste water can be red
The prognosis of HIV-1-infected patients has dramatically improved but progression to liver failure occurs now frequently in subjects coinfected with hepatitis C virus (HCV). This has raised the issue of organ transplantation, but the knowledge about the effect of concomitant antiretroviral and immunosuppressive therapy is limited. The objective of the study was to describe viral and immunological
Failure to account for non-climatic changes to water systems, such as design and operation, within climate change impact assessments leads to misconceptions because these activities buffer the human built enviroment from bio-physical impacts. Urban drainage in cold regions, which is dominated by snowmelt, is especially vulnerable to climate change and is investigated in this paper within the conte
The detailed mechanisms which can explain the inherent radiosensitivity of salivary glands remain to be elucidated. Although DNA is the most plausible critical target for the lethal effects of irradiation, interactions with other constituents, such as cell membrane and neuropeptides, have been suggested to cause important physiological changes. Moreover, mast cells seem to be closely linked to rad
Carotenoids are, along with chlorophylls, crucial pigments involved in light-harvesting processes in photosynthetic organisms. Details of carotenoid to chlorophyll energy transfer mechanisms and their dependence on structural variability of carotenoids are as yet poorly understood. Here, we employ femtosecond transient absorption spectroscopy to reveal energy transfer pathways in the peridinin-chl
We show that arrays of nanopit structures etched in a nanoslit can control the positioning and conformation of single DNA molecules in nanofluidic devices. By adjusting the spacing, organization and placement of the nanopits it is possible to immobilize DNA at predetermined regions of a device without additional chemical modification and achieve a high degree of control over local DNA conformation
Disturbances in intestinal metabolism and perfusion during SIRS can be direct effects of toxic substances, and/or effects secondary to hypovolemia. An attempt to evaluate the significance of hypovolemia for intestinal disturbances during SIRS was made in the present study on feline by evaluating the degree to which the intestinal alterations following endotoxin infusion were restored by a clinical
