Let S be a set of points in the plane. What is the minimum possible dilation of all plane graphs that contain S? Even for a set S as simple as five points evenly placed on the circle, this question seems hard to answer; it is not even clear if there exists a lower bound >1. In this paper we provide the first upper and lower bounds for the embedding problem. 1. Each finite point set can be embedded
The alkaline sphingomyelinase (SMase) was first found in rat intestinal brush border. The important roles of this enzyme in digestion of sphingomyelin and in mucosal cell proliferation have been suggested. In the present work, the distribution of the alkaline SMase in the tissues of human beings and animals have been studied. By assaying the enzyme activity in human biopsy samples, we found that t
In this study, we assessed the proliferative response of peripheral blood mononuclear leukocytes (PBML) from 33 children/young adolescents with chronic dyspepsia, to H. pylori LPS in the presence and absence of IL-2 as a T cell growth factor. A rapid urease test (RUT) and a presence of Helicobacter-like organisms (HLO) in the biopsy specimens allowed us to distinguish RUT/HLO-positive (17/33) and
Previously, we found that emergence of the X4 viral phenotype in HIV-1-infected children was related to the presence of X4 in their mothers (C. H. Casper et al., J Infect Dis 2002; 186: 914-921). Here, we investigated the origin of the X4 phenotype in the child, analyzing two mother-child pairs (Ma-Ca, Mb-Cb) where the mothers carried X4 and their children developed X4 after an initial presence of
Objective: The aim of the first Nordic mantle cell lymphoma (MCL) protocol was to study the clinical significance of an augmented CHOP induction chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT) and to examine the prognostic significance of stem cell contamination rates in newly diagnosed patients with MCL. Patients and methods: Forty-one newly diagnos
Intense continua of electromagnetic radiation of very brief duration are formed in the interaction of focused ultra-short terawatt laser pulses with matter. Two different kinds of experiments, which have been performed utilizing the Lund 10 Hz titanium-doped sapphire terawatt laser system are being described, where visible radiation and X-rays, respectively, have been generated. Focusing into wate
Popular Abstract in Spanish Resumen En esta tesis se describe el desarrollo y la posterior aplicación en el aula de los Modelos Didácticos del Subjuntivo 1 y 2, cuyo mecanismo se centra en la utilización de una pregunta con la cual el estudiante podrá hacer la elección modal más adecuada para cada caso. El modelo unifica conceptos y valores adjudicados al subjuntivo y presenta la gramática desde uAbstract In the present thesis the development and subsequent implementation of the Didactic Models 1 and 2 of the Subjunctive is described. The models focus on the use of a question, with which the student makes the most adequate mode choice for each case. The model unifies perspective and meaning used with the subjunctive from a cognitive perspective, appealing to the inherent representational c
Context: Effect of GH therapy in short non GH deficient children, especially idiopathic short stature (ISS) has not been clearly established owing to lack of controlled trials until final height (FH). Objective: To investigate the effect of two GH doses compared with untreated controls on growth to FH in short children mainly with ISS. Design and Setting: A randomized, controlled, long-term multic
Popular Abstract in Swedish Ett bröstmjölksprotein som dödar tumörceller Denna avhandling beskriver den tumörcell- och bakteriedödande effekten av ett proteinkomplex från bröstmjölk. Proteinkomplexet, en veckningsvariant av humant alfa-laktalbumin, inducerar apoptos (programmerad celldöd) i tumörceller och visar sig ha liknande effekter även mot bakterier. Amning förser inte bara barnet med optiHuman milk contains a vast array of bioactive molecules, with nutritional and protective functions. This thesis describes the effects of a human milk protein complex, MAL, on tumour cells and bacteria. During our studies on the anti-adhesive properties of human milk we observed that a milk fraction killed tumour cells. The morphology of the cells indicated apoptotic cell death and this was verifie
The marine environment harbors a large proportion of the total biodiversity on this planet, including the majority of the earths’ different phyla and classes. Studying the genomes of marine organisms can bring interesting insights into genome evolution. Today, almost all marine organismal groups are understudied with respect to their genomes. One potential reason is that extraction of high-quality
The measurement of absorbed dose distributions using dosemeter gel and magnetic resonance imaging (MRI) in a standard geometry has been investigated. Absorbed depth-dose curves and profiles measured with this new technique show good agreement with corresponding measurements using diodes. This was proven in a 60Co beam as well as an electron beam. The dosemeter gel is made of agarose and ferrous su
Fms-like tyrosine kinase (FLT3) is a frequently mutated oncogene in acute myeloid leukemia (AML). FLT3 inhibitors display promising results in a clinical setting, but patients relapse after short-term treatment due to the development of resistant disease. Therefore, a better understanding of FLT3 downstream signal transduction pathways will help to identify an alternative target for the treatment
BackgroundSexual violence is widespread in the eastern parts of the Democratic Republic of the Congo, including in the North Kivu province. Moreover, in this region survivors of sexual violence often have limited access to care and encounter a variety of barriers when seeking care and support. The aim of this study was to explore community perceptions about access to care, barriers, enablers and p
