An unprejudiced revision of the genus Pilosella (Asteraceae) in the Nordic countries has been attempted. A completely new system for the taxonomy of these mostly facultative apomicts is presented. It is argued that all existing systems are inappropriate in the light of the complicated, and largely unknown, reproductive biology of these taxa. Previous systems have either treated these taxa as oblig

Background. Genital prolapse is a common and handicapping form of pelvic floor dysfunction. To explain its genesis as a result of endopelvic connective tissue weakness, the collagen state was analyzed in women with and without genital prolapse. Methods. Punch biopsies from the paraurethral ligaments were obtained during the operation from 22 women undergoing surgery for genital prolapse. As contro

Objective: To assess the absorption of dietary selenium in humans, especially of milk selenium. Design: 1-day meal studies in subjects with ileostomy. Setting: Hospital outpatient clinics. Subjects: Three subjects in the pilot study and nine subjects in the main study ( eight men/four women). Intervention: Different beverages, 1 l/day, were given in addition to basal diets ( soft drink, 1 week; lo

The planning and construction of a facility can affect several interests. Positive effects are, for instance, better communications, better housing and a higher standard of living. However, construction projects inevitably bring varying degrees of deterioration and change at the local level, not least at the construction site. Representatives of these interests are referred to as the project's sta

Blood monocytes which differentiate into tissue macrophages, are unique in that they can not only initiate immune responses but can also be effector cells which contribute to the resolution of these responses. There is no single activation phenotype, and macrophages can be induced to differentiate into cells that either exacerbate or inhibit acute inflammation. Similarly, these cells can promote,

A haemagglutinating monoclonal anti-LebL antibody has been obtained from a mouse-mouse hybridoma after immunization with the Leb-active oligosaccharide lacto-N-difucohexaose I, coupled to edestin. Of 13 other antibodies obtained, one was able to agglutinate enzyme-treated erythrocytes of all ABO groups and three more were considered to be anti-LebH haemagglutinins. The remaining nine antibodies di

Background: BRCA1 is a tumour suppressor with pleiotropic actions. Germline mutations in BRCA1 are responsible for a large proportion of breast - ovarian cancer families. Several missense variants have been identified throughout the gene but because of lack of information about their impact on the function of BRCA1, predictive testing is not always informative. Classification of missense variants

Src homology 2 (SH2) and SH3 domains are abundant protein and peptide binding modules in signalling molecules. Certain SH2 and SH3 domains have been shown to form functional and physical interactions. The structural basis of dimer formation was studied by docking three dimensional structures of the domains and by analysing structural and functional properties of the dimers. The experimentally veri

Objectives To determine the accuracy of established ultrasound dating formulae when used at 12-14 weeks of gestation. Methods One-hundred and sixty-seven singleton pregnancies conceived after in-vitro fertilization (IVF) underwent a dating scan at 12-14 weeks of gestation. Gestational age at the dating scan was calculated by adding 14 days to the number of days between the date of oocyte retrieva

The thesis describes methods for automatic creation of illustrations of natural-language text. The main focus of the work is to convert texts that describe sequences of events in a physical world into animated images. This is what we call text-to-scene conversion. The first part of the thesis describes Carsim, a system that automatically illustrates traffic accident newspaper reports written in

CCND1 amplification results in cyclin D1 overexpression. However, other unidentified genetic mechanisms contribute to enhanced gene expression. In the present study, 32 squamous cell carcinoma of the head and neck (SCCHN) were investigated regarding chromosomal abnormalities involving 11q13 by cytogenetic analysis, genomic CCND1 amplification by differential PCR and FISH, and cyclin D1 expression

Since January 2006, robotic assistance has been used for performing minimal invasive laparoscopic fundoplications in children. These patients were compared with those operated on with either the open surgical technique or the laparoscopic procedure. The first six children operated on with a fundoplication using the operation robot, da Vinci (R) Surgical System from Intuitive Surgical (R), were inc

Malignant melanoma of soft parts (MMSP), also called clear cell sarcoma of tendons and aponeuroses, is cytogenetically characterized by the t(12;22)(q13;q12) resulting in the chimeric EWSR1/ATF1 gene. MMSP shares a number of morphologic, histologic, and immunohistochemical features with malignant melanoma of the skin, causing diagnostic difficulties in the distinction between MMSP and metastatic m

A simple technique for fine-needle aspiration biopsy from the synovial membrane of arthritis knee joints preceded by lavage of the joint cavity is described. The procedure was atraumatic, well accepted, and could be performed on outpatients. Cells originating from the synovial membrane were obtained in 12 of 17 knees using a 1.2-mm cannula. The yield was 6.0 x 10(3) to 135 x 10(3) mononuclear cell
