The purpose of this study was to assess the value of the ventilation study in the diagnosis of acute pulmonary embolism using a new automated method. Either perfusion scintigrams alone or two different combinations of ventilation/perfusion scintigrams were used as the only source of information regarding pulmonary embolism. A completely automated method based on computerised image processing and a

The room-temperature Raman and infrared spectra of zirconium vanadate (ZrV2O7) were observed up to pressures of 12 GPa and 5.7 GPa, respectively. The frequencies of the optically active modes at ambient pressure were calculated using direct methods and compared with experimental values. Average mode Gruneisen parameters were calculated for the Raman and infrared active modes. Changes in the spectr

Popular Abstract in Swedish I fem autopsistudier undersöktes humana käkledspreparat med tomografi (skiktröntgen), makroskopiskt (inspektion) och mikroskopiskt för förekomst av degenerativa (nedbrytande) förändringar. Speciellt undersöktes förekomst av erosiva förändringar i benet samt förändringar i den förkalkade broskzonen (skiktet mellan mjukbrosk och ben). Det förkalkade brosket var i normalaIn five autopsy specimen studies human temporomandibular joints were investigated by conventional tomography, macroscopy, and microscopy for degenerative changes, in particular erosive hard-tissue changes.In the microscopical evaluation special attention was paid to the calcified cartilage. The calcified cartilage was outlined by a flat or gently undulating basophilic tidemark and an irregular os

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

BACKGROUND: Cyclin A1 is a cell cycle regulator that has been implicated in the progression of prostate cancer. Its role in invasion and metastasis of this disease has not been characterized. METHODS: Immunohistochemistry and cDNA microarray analyses were used to assess protein and mRNA expression of cyclin A1 and proteins with roles in metastasis, including vascular endothelial growth factor (VEG

The paper describes a novel extraction procedure for lipopolysaccharides (LPS) from Salmonella enterica subsp. enterica (PCM 2266). Process parameters for the extraction of LPS from bacterial mass were optimized by carrying out a two-level fractional design experiment. Four parameters, namely temperature, CO, flow rate, pressure and co-solvent composition were analyzed. The best crude extract yiel

Most people in the world and about a fifth of all school-aged Americans speak at least two languages. Nevertheless, little is known about second language (L2) processing in development, even though language proficiency is strongly related to success in almost all domains. Whereas behavioral studies of L2 acquisition in children are abundant, neurocognitive studies of L2 processing typically are li

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Skivepitelcancer i huvud- och halsregionen (SCCHN) Kliniska aspekter Prognosen vid SCCHN är i stort sett oförändrat dålig sedan 30 år tillbaka; cirka hälften av patienterna dör av sin sjukdom. Trots stora tekniska framsteg kring behandlingsteknikerna (ofta en kombination av kirurgi, strål- och i viss mån cellgiftsbehandling) medför dAt present, clinical outcome or response to therapy can not be fully predicted in individual cases of squamous cell carcinoma of the head and neck (SCCHN). The overall aim of the present studies was to investigate potential prognostic factors, more closely related to the malignant progression of a tumor than the established markers, such as the TNM-classification system. Tumor samples were investi

OBJECTIVE: To examine the predictive capability of a 1-h vs 2-h postload glucose value for cardiovascular morbidity and mortality.DESIGN: Prospective, population-based cohort study (Malmö Preventive Project) with subject inclusion 1974-1992.RESULTS: Median age was 48 (25th-75th percentile: 48-49) years and mean FBG 4.6 ± 0.6 mmol/L. FBG and 2-h postload BG did not independently predict cardiovascu

Access to compatible blood for transfusion is a prerequisite for modern health care. The compatibility is limited by the presence of antibodies to blood group antigens, polymorphic protein and carbohydrate structures, on the surface of the red blood cell. Blood group antigens arise from genetic variation in the genes underlying their expression. Knowledge of these genes and their variation can fac

BACKGROUND: Musculoskeletal (MSK) disorders are less likely to be reported as an underlying cause of death (UCD) and since cause of death studies are generally limited to the UCD, little is known about socioeconomic inequalities in MSK disorders as cause of death in the general population. Using multiple-cause-of-death data, we aimed to quantify and compare educational inequalities in musculoskele

Syftet med studien är att undersöka det förbättrade upptaget av det radioaktiva spåret Technetium-99m-DTPA (99mTc-DTPA) i råtta Muskelvävnad i Fischer 344 råttor efter applicerade elektriska pulser med olika fältstyrka och pulslängd,Metoder: 99mTc-DTPA (totalt 150 MBq) administrerades intramuskulärt (i.m.) vid axeln som en bolus i flera fraktioner av 50 l vardera i intervaller på 1 minut.

Diffusion kurtosis imaging (DKI) allows for assessment of diffusion influenced by microcellular structures. We analyzed DKI in suspected low-grade gliomas prior to histopathological diagnosis. The aim was to investigate if diffusion parameters in the perilesional normal-appearing white matter (NAWM) differed from contralesional white matter, and to investigate differences between glioma malignancy

The water sector in Somalia is fragmented and needs coordination to establish a functioning water governance system. Therefore, commitments from all affected stakeholders are needed to support water resources development in Somalia. This paper proposed a water compact for Somalia that can address all water sector challenges to approach sustainability. The paper starts by analyzing water sector sta

Morocco has for twenty years been in what is officially described as a transition to democracy. During the former king Hassan II negotiations with the opposition resulted in two constitutional reforms and a new government in 1998 dominated by the former opposition parties. In the 2000s two important law reforms were made: a new law of personal status in 2004 and a new constitution in 2011. The new
