Objectives: To determine if tumor vascularity as assessed by three-dimensional (3D) power Doppler ultrasound can be used to discriminate between benign and malignant ovarian tumors, if adding 3D power Doppler ultrasound to gray-scale imaging improves differentiation between benignity and malignancy, and if 3D power Doppler ultrasound adds more to gray-scale ultrasound than does two-dimensional (2D

Popular Abstract in Swedish Hawaiianernas liv och historia har dokumenterats allt sedan första kontakten med västerländska äventyrsresanden i slutet av 1700-talet. I samband med amerikanska missionärers ankomst år 1820 introducerade och etablerade dessa missionärer en puritansk lära och kunskapsförmedling via det skrivna ordet. Mötena mellan de olika kulturerna har beskrivits som fredliga. Dock haThe life and history of the Hawaiians has been documented ever since the contact with Western adventurers at the end of the 18th century. In connection with the arrival of American missionaries in 1820, these missionaries introduced and established a puritanical doctrine and method of communicating knowledge by way of the written word. The encounters between the different cultures have been descri

Based on a retrospective study of 19 neuropathologically verified cases with frontotemporal dementia (FTD), neuropsychiatric symptoms related to behavioral disturbances and their psychosocial consequences were studied. The results indicate that frontotemporal dementia is often misdiagnosed early in the clinical course. Behavioural features with impaired social interactions, impaired personal regul

Triglycerides and phospholipids in human liver material obtained by fine-needle aspiration biopsy have been determined according to an improved version of a previously developed method. The molar ratios of these lipids have been compared with the same ratios determined on material representing whole liver. The average value of the ratios in the fine-needle specimens was 101% (83-113%) of the corre

The effects of cystatin C and other cysteine proteinase inhibitors on osteoclast formation and differentiation have been investigated. Cystatin C decreased osteoclast formation stimulated by parathyroid hormone (PTH), 1,25(OH)(2)-vitamin D3 or interleukin-6 (IL-6) (in the presence of its soluble receptor) as assessed by the number of tartrate-resistant acid phosphatase (TRAP(+)) multinucleated cel

PURPOSE: To compare conventional MR imaging, echo-planar diffusion-weighted imaging (EP-DWI) and spin-echo diffusion-weighted imaging (SE)-DWI at radiological diagnosis of acute stroke. MATERIAL AND METHODS: Twenty-seven patients (30-85 years old) were examined. Clinical examination was performed before MR imaging. All MR examinations were assessed by an experienced neuroradiologist blinded to cli

Dose calculations for treatment planning of photon beam radiotherapy require a model of the beam to drive the dose calculation models. The beam shaping process involves scattering and filtering that yield radiation components which vary with collimator settings. The necessity to model these components has motivated the development of multisource beam models. We describe and evaluate clinical photo

Popular Abstract in Swedish Medborgarlön - ett statligt bidrag som ges till alla medborgare utan inkomst- eller behovsprövning - har varit flitigt diskuterat inom akademiska kretsar under senare år. Bland argumenten för medborgarlön återfinns att det antas ge ett erkännande åt obetalt arbete inom hemmet, en mer jämlik fördelning av lönearbete genom att uppmuntra deltidsarbete, leda till minskad ofBasic income - an income granted by the government to each full member of society without means tests or work requirements - has been a widely discussed subject among academics in recent years. However, basic income has not, in most cases, reached the formal political agenda. The main aim of this book is to discuss why this is the case, with Sweden as the focus of the discussion. The aim is also t

The discovery of multipotent neural progenitor (NP) cells has provided strong support for the existence of neurogenesis in the adult brain. However, the signals controlling NP proliferation remain elusive. Endocannabinoids, the endogenous counterparts of marijuana-derived cannabinoids, act as neuromodulators via presynaptic CB1 receptors and also control neural cell death and survival. Here we sho

Rodent models have been developed to study the pathogenesis of diseases caused by Helicobacter pylori, as well as by other gastric and intestinal Helicobacter spp., but some murine enteric Helicobacter spp. cause hepatobiliary and intestinal tract diseases in specific inbred strains of laboratory mice. To identify these murine Helicobacter spp., we developed an assay based on PCR-denaturing gradie

The relationship between urinary levels of cotinine (U-cotinine) and arsenic (U-As), blood levels of cadmium (B-Cd), blood levels of lead (B-Pb), lung function, and questionnaire data on smoking habits were studied in 107 parents and their 46 children (7-10 y of age). There was a statistically significant relationship between the reported amount of tobacco smoked and U-cotinine levels. Nonsmokers

Background Several models for prediction of acute coronary syndrome (ACS) among chest pain patients in the emergency department (ED) have been presented, but many models predict only the likelihood of acute myocardial infarction, or include a large number of variables, which make them less than optimal for implementation at a busy ED. We report here a simple statistical model for ACS prediction th
