Immunochemical characterization of a monoclonal anti-Leb blood grouping reagent

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

Classification of BRCA1 missense variants of unknown clinical significance

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

Interactions between SH2 and SH3 domains

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

Ultrasound dating at 12-14 weeks of gestation. A prospective cross-validation of established dating formulae in in-vitro fertilized pregnancies.

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

Natural Language Processing Methods for Automatic Illustration of Text

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

Chromosomal translocations involving 11q13 contribute to cyclin D1 overexpression in squamous cell carcinoma of the head and neck

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

Robotic fundoplication in children

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

Absence of mutations of the BRAF gene in malignant melanoma of soft parts (clear cell sarcoma of tendons and aponeuroses)

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

Mononuclear cells recovered from inflammatory synovial membrane using fine-needle biopsy

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

Corticosteroid-binding globulin: A possible early predictor of infection in acute necrotizing pancreatitis

Objective. Infected pancreatic necrosis is the main cause of death in patients with acute pancreatitis, and therefore its early prediction is of utmost importance. Endogenous cortisol metabolism plays a basic role both in the course of acute pancreatitis and in the process of infection. The purpose of this study was to analyze corticosteroid-binding globulin (CBG), total cortisol, calculated free

Erospedagogik. Från Platon till Areopagites

"Eros pedagogy. From Plato to Areopagite" is a philosophical-pedagogical essay which emphasizes the educational dimension in the philosophy of eros as presented by Plato, and further, through Neoplatonism, interpreted and introduced by Areopagites into Christian thought. At first the essay describes the theory of Plato on eros as part of his general system of thought and here the pedagogic element

Triiron and triruthenium carbonyl clusters bearing bridging long chain diphosphine and capping chalcogenido ligands

Treatment of Ru-3(CO)(12) with dpphSe(2) (dpph = 1,6-bis(diphenylphosphino)-hexane) in refluxing toluene in the presence of Me3NO afforded two new compounds, Ru-3(CO)(7)(mu-CO)(mu(3)-Se)(mu-dpph) (1) and Ru-3(CO)(7)(mu(3)-Se)(2)(mu-dpph) (2). A similar reaction of Ru-3(CO)(12) with dpppeSe(2)(dpppe=1,5-bis(diphenylphosphino)pentane) gave exclusively Ru-3(CO)(7)(mu(3)-Se)(2)(mu-dpppe) (3). Treatmen
