Background and aims: Several studies report a high prevalence of memory complaints in the elderly, non-demented population. Since the pathogenesis and diversity of memory impairment in healthy people is still an unresolved issue, we designed our study to ascertain the occurrence of brain abnormalities in Age-Associated Memory Impairment (AAMI) by measuring regional cerebral blood flow (rCBF). Meth

The etiology of exercise-induced rib stress fractures (RSFs) in elite rowers is unclear. The purpose of the study was to investigate thoracic muscle activity, movement patterns and muscle strength in elite rowers. Electromyographic (EMG) and 2-D video analysis were performed during ergometer rowing, and isokinetic muscle strength was measured in seven national team rowers with a history of RSF and

We study the stability and structure of vortices emerging in two-dimensional quantum dots in high magnetic fields. Our results obtained with exact diagonalization and density-functional calculations show that vortex structures can be found in various confining potentials. In nonsymmetric external potentials we find off-electron vortices that are localized giving rise to charge deficiency or holes

To find out how the ‘generic person’ is expressed in English and Swedish, the use and correspondence of the generic pronouns one in English and man in Swedish are examined in a bidirectional English-Swedish translation corpus. The material demonstrates clearly the greater frequency and versatility of Swedish man and the restricted use of English one. The difference is partly register-related: whil

The aim of this study was to analyse whether the interleukin-1 (IL-1) and IL-6 gene polymorphisms were associated with the susceptibility of chronic periodontitis. Genomic DNA was obtained from 20 patients with chronic periodontitis and 31 periodontally healthy subjects. All subjects were of North European heritage. The test subjects were kept in a maintenance program after periodontal treatment b

Wireless mesh networks (WMN) have attracted consider- able interest in recent years as a convenient, flexible and low-cost alternative to wired communication infrastructures in many contexts. However, the great majority of research on metropolitan-scale WMN has been centered around max- imization of available bandwidth, suitable for non-real-time applications such as Internet access for the genera

The exact diagonalization technique is used to study many-particle properties of interacting electrons with spin, confined in a two-dimensional harmonic potential. The single-particle basis is limited to the lowest Landau level. The results are analysed as a function of the total angular momentum of the system. Only at angular momenta corresponding to the filling factors 1, 1/3, 1/5, etc is the sy

InledningDet är kväll den 15:e januari 2004. Idag var det den andra dagen i Mijailovic-rättegången i Stockholms tingsrätt. Mijailovic försvarar sig, men inte genom att svara på frågor. Han representerar det moderna. Hans psykos, säger han, fick honom att få panik, höra röster och döda en utrikesminister. Om han fått träffa en läkare skulle allt varit annorlunda. Sedan början av 1800-talet har dett

OBJECTIVE: To compare the frequency of rebleeding and endometrial growth during a 12-month follow-up period between women with postmenopausal bleeding and an endometrial thickness < 5 mm managed by dilatation and curettage, and those managed by ultrasound follow-up. DESIGN: Consecutive women with postmenopausal bleeding and an endometrial thickness < 5 mm were randomized to ultrasound follow-up af

Parkinson's disease (PD) patients display motor symptoms, e.g. tremor, rigidity and bradykinesia, largely due to a dramatic loss of dopaminergic neurons in the substantia nigra. Grafts of human embryonic dopamine neurons can survive in the striatum and reduce several of the motor symptoms. Several lines of evidence suggest that a crucial threshold of surviving dopaminergic neurons must be exceeded

The Integrated Deposition Model (IDEM) was improved by incorporating a novel multilayer biochemical dry deposition module for gases. The aerosol and base cation deposition module was adopted from IDEM. For evaluation of primary and ecosystem productivity, carbon respiration schemes were included. The resulting Framework for Atmosphere- Canopy Exchange Modelling (FACEM) was then evaluated by the ca
