BACKGROUND: Proper treatment of lymph node-negative breast cancer depends on an accurate prognosis. To improve prognostic models for this disease, we evaluated whether an immunohistochemical marker for proliferating cells, Ki-S2 (a monoclonal antibody that binds to a 100-kd nuclear protein expressed in S, G2, and M phases of the cell cycle), is an accurate indicator of prognosis.METHODS: We studie

Background Subjective evaluation of gray-scale and Doppler ultrasound findings (i. e., pattern recognition) by an experienced examiner and preoperative serum levels of CA-125 can both discriminate benign from malignant adnexal ( i. e., ovarian, paraovarian, or tubal) masses. We compared the diagnostic performance of these methods in a large multicenter study. Methods In a prospective multicenter s

An extensive follow-up study of day- and night-active Macrolepidoptera was performed during 2004 at the Kullaberg Nature Reserve located in the south-western part of Sweden. Butterflies were surveyed in an area of 100 km(2) and night-active moths were trapped in the core area of the reserve. Macrolepidopteran species resident in the area in the 1950s were compared with species resident in the area

Tailbiting codes are error correcting codes and can be used in digital transmission systems. They are obtained by terminating convolutional codes into block codes. This thesis consists of an introduction to convolutional and tailbiting codes, and the Papers A--G that include the main results. In Paper A, the error correcting capability of tailbiting codes is described via the active distances for

The problem of empty names derives from the fact that empty names fail to refer. The reference failure of empty names implies that sentences containing empty names lack truth-conditions. As a consequence those sentences are meaningless, according to many theories of meaning. The present dissertation addresses the problem of empty names and proposes a solution to the problem at hand. In brief, the

Borderline Personality Disorder (BPD) has largely been associated with self-harm and chronic suicidality, despite the fact that these behaviours comprise only one diagnostic criterion. Treatments for self-harm are mostly indicated for individuals with BPD. Emerging literature suggests that youth with histories of depression are at risk of both self-harm and completed suicide. For individuals with

The study accounts for recent developments in corporate voluntarism and assesses the evolving corporate social responsibility (CSR) regime. CSR proposes a new norm for how large businesses should approach complexity in a modern economy. The first chapter anchors the CSR discussion in a company law and corporate governance context. Emphasis is placed on managerial duties and the British Review of C

Aim: To characterize early amplitude-integrated electroencephalogram (aEEG) and single-channel EEG (aEEG/EEG) in very preterm (VPT) infants for prediction of long-term outcome. Patients: Forty-nine infants with median (range) gestational age of 25 (22-30) weeks. Methods: Amplitude-integrated electroencephalogram/EEG recorded during the first 72 h and analysed over 0-12, 12-24, 24-48 and 48-72 h,

Try to imagine a fire emergency evacuation. What is the first image that you have in your mind? Here there are some guesses. Probably a parent running inside a house trying to rescue her children, but not managing since she is too scared? An old man stuck crying in a corner of a room with flames and smoke all around him? Or a group of people crushing aggressively against each other in order to get

We present age- and gender-specific normative bone status data evaluated by quantitative ultrasound (QUS) in the calcaneus with the Lunar Achilles device and compare these estimates with bone mineral content (BMC) and bone mineral density (BMD) estimated by dual X-ray absorptiometry (DXA). Included were a sample of 518 population-based collected Swedish girls and 558 boys aged 6-19 years. QUS meas

Background: Computed tomography (CT) of the brain is performed with high local doses due to high demands on low contrast resolution. Advanced algorithms for noise reduction might be able to preserve critical image information when reducing radiation dose.PurposeTo evaluate the effect of advanced noise filtering on image quality in brain CT acquired with reduced radiation dose. Material and Method

Bias caused by collecting and processing bulk samples is largely independent of what fossil clade or mineral is searched for. Instead, different methods bias the data to a different, frequently very large, degree. Furthermore, biases accumulate with each recovery step, and the sum may be extreme unless appropriate methods to minimize it are employed. The effects depend on what the data are used fo

This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. swirl, stagnation points and anisotropic turbulence. Also, using LES one can obta

Popular Abstract in Swedish Bildundervisningen i grundskolans tidigare år uppfyller inte de i Sverige uppsatta målen. De nationella utvärderingarna (NU 89) och (NU92) bekräftar detta. Lärarna säger att de saknar ämneskunskaper och utvärderingarna visar att inslag från äldre läroplaner präglar undervisningen. För att ge en bild av hur nuvarande problem kan ha uppstått presenteras i studien en histoThe art education in Swedish primary and secondary schools is far from perfect and as a result pupils seldom reach the desired standard. National evaluations in 1989 and 1992 confirm this. Teachers admit that they lack specific subject knowledge and evaluation reveals that many aspects of older curricula still prevail. The way in which the present problems may have arisen is described through the

Atrial fibrillation is the most common cardiac arrhythmia that demands medical attention. Computer-based detailed analysis of cardiac electrical signals from healthy subjects and patients with a history of atrial fibrillation has become an important tool in the further clarification of this disease. The aim of this study was to explore supraventricular conduction using the following selected techn

Popular Abstract in Swedish Nollvisionen antagen av Sveriges riksdag fastlägger att ingen skall behöva dödas eller skadas svårt i trafiken i Sverige. Införande av detta begrepp förskjuter fokus från trafikolyckorna till konsekvenserna av trafikolyckorna och härmed skapas förutsättningar för ett paradigmskifte i trafiksäkerhetsarbetet. För att åstadkomma önskade förändringar är det nödvändigt och bThe over-arching objectives of this thesis were to formulate a method to describe the consequences of traffic casualties, and to explain the influence of different traffic engineering factors on these consequences for society and individuals over time. A more detailed objective was to examine whether available short-term indicators can be used to predict consequences in a long-term perspective. Ot
