Vascular dementia - classification and clinical correlates

Popular Abstract in Swedish Demens är ingen enhetlig sjukdom utan ett syndrom dvs en beteckning på en grupp symtom, som beskriver en långvarig försämring av hjärnans psykiska funktioner. Demens kan ha olika klinik profil och orsakas av olika skador och sjukdomar. Den vanligaste demenssjukdomen är Alzheimers sjukdom. Kring denna sjukdom finns mycket forskning gjord. Vaskulär demens är den näst vanlDuring the period (1976-1995) a total of 175 consecutive patients (m 88/f 87) with neuropathologically verified vascular dementia (VaD) were examined. 22 patients with pure Alzheimer's Disease (AD) were also studied. All patients were diagnosed and followed at the Department of Psychogeriatrics (Lund University Hospital). The neuropathological examination revealed VaD, sometimes with additional co

Views of patients with heart failure about their role in the decision to start implantable cardioverter-defibrillator treatment: prescription rather than participation

Background: There is a shortage of reports on what potential recipients of implantable cardioverter-defibrillators ( ICDs) need to be informed about and what role they can and want to play in the decision-making process when it comes to whether or not to implant an ICD. Aims: To explore how patients with heart failure and previous episodes of malignant arrhythmia experience and view their role in

Neuronal signal substances as biomarkers of migraine

Of the sensory nervous system associated signal substances it is only calcitonin generelated peptide (CGRP) that is reliably associated with the degree of pain in the acute attacks of primary headaches. The treatment with triptans alleviates both the pain and the associated CGRP release, putatively via a presynaptic effect on the sensory nerves. The studies of opoids and other sensory neuropeptide

Time-resolved X-ray diffraction study of the ferroelectric phase-transition in DKDP

We have performed experiments where DKDP has been irradiated by short (100 fs), laser pulses. Subsequently X-ray pulses with a duration of 100 ps were used as a probe. Time-resolved X-ray diffraction enables monitoring of the transitions between the paraelectric and ferroelectric phases. By recording the intensity of a peak only present in the paraelectric phase, we observe indications of a phase-

Mild and efficient direct aromatic iodination

Aryl iodides are important synthetic intermediates that can be transformed into tritium labelled compounds by metal-mediated hydrodehalogenation and also react in a number of important synthetic transformations. We present ICI/ln(OTf)(3) as a new reagent combination for mild iodination, suitable for acid-sensitive substrates such as carbohydrates. (c) 2005 Elsevier Ltd. All rights reserved.

Theoretical study of electromagnetically induced transparency in Er3+: YAlO3 crystal

By using the density matrix theory of interaction between light and matter, and relevant parameter calculations of the relaxation rate, the dipole matrix elements and the ion density for a three-level ladder model, we have discussed theoretically the possibility to realize electromagnetically induced transparency (EIT) in Er3+:YA1O(3) crystal.

Measurement of dijet cross sections in photoproduction at HERA

Dijet cross sections as functions of several jet observables are measured in photoproduction using the HI detector at HERA. The data sample comprises e(+)p data with an integrated luminosity of 319 pb(-1). Jets are selected using the inclusive k(perpendicular to) algorithm with a minimum transverse energy of 25 GeV for the leading jet. The phase space covers longitudinal proton momentum fraction x

Effects of ionising and non-ionising radiation in cell systems and a rat model for immuno-therapy

The most malignant brain tumour, glioblastoma multiforme (GBM), has an utterly bad prognosis. In spite of all available therapy, the mean survival time is less than a year. In the unique BRIGTT project (Brain Immuno Gene Tumour Therapy), patients at the Dept of Neurosurgery. Lund University Hospital, are immunised with their own glioma cells, which have been transfected with the immunostimulatory

Involvement of eicosanoid signalling in epithelial cell migration

The development of inflammatory bowel diseases (IBD) and colon cancer (CC) has been shown to involve the up-regulation of inflammatory mediators and the machinery producing them such as the eicosanoids. Changes in the expression of extracellular matrix proteins and their related integrin receptors have also been shown to be important in the advancement IBD and CC. In light of this, we have investi

Energy use in multi-family dwellings : measurements and methods of analysis

In 2001, multi-family dwellings were built at nine properties in Västra hamnen, Malmö, Sweden. Several well known Swedish architects were involved in designing the buildings, hence they reflect modern architecture. Prior to the inauguration, the buildings were displayed at the international housing exhibition Bo01. The housing exhibition had an ecological and sustainability focus. Regarding energy

Sex pheromone for monitoring flight periods and population densities of the pine sawfly, Diprion jingyuanensis Xiao et Zhang (Hym., Diprionidae)

The pine sawfly, Diprion jingyuanensis Xiao et Zhang, is a serious pest of Chinese pine (Pinus tabulaeformis Carr.) in the northern parts of China. The general biology of this recently described sawfly species is little known and in the present study we used a synthetic pheromone to monitor its flight period and to evaluate the possibility to use pheromone traps as a tool for estimating and predic
