The prevalence of Helicobacter pylori is high in Eastern Europe. The purpose of this study was to estimate the prevalence of H. pylori in symptomatic Lithuanian children and to identify the infection by clinicopathological and serological analyses. One hundred sixteen symptomatic children (age 8-16) with gastritis and duodenal ulcer were included. Biopsies were histologically assessed according to

In this study stool samples from dyspeptic patients and healthy subjects were used for detection of specific Helicobacter pylori antigens and DNA by immunoenzymatic test (PPHpSA) and semi-nested PCR (ureA-PCR), respectively. The H. pylori status was estimated by invasive endoscopy-based rapid urease test and histology or noninvasive urea breath test (UBT), and by serology (ELISA, Western blot). Th

Nanoparticles present enormous surface areas and are found to enhance the rate of protein fibrillation by decreasing the lag time for nucleation. Protein fibrillation is involved in many human diseases, including Alzheimer's, Creutzfeld-Jacob disease, and dialysis-related amyloidosis. Fibril formation occurs by nucleation-dependent kinetics, wherein formation of a critical nucleus is the key rate-

The reaction kinetics for a number of reductive openings of methyl 2,3-di-O-benzyl-4,6-O-benzylidene-alpha-d-glucopyranoside have been investigated. Openings to give free HO-6 (using BH(3).THF-AlCl(3)-THF or LiAlH(4)-AlCl(3)-Et(2)O) follow first order kinetics, while reactions yielding free HO-4 (using BH(3).NMe(3)-AlCl(3)-THF or BH(3).NMe(3)-BF(3).OEt(2)-THF) follow higher order kinetics. The add

By analysing two different Female Gothic novels, this thesis aims to explore the different ways in which masculinity is portrayed within the Female Gothic literary tradition, more specifically the Early Gothic and Victorian Gothic due to constraints in scope. The novels chosen, The Mysteries of Udolpho (1794) and Uncle Silas (1864), are in many ways representative and serve as typical Female Gothi

This thesis will be concerned with one of the main concerns and highly discussed topics in the relationship between Article 102 TFEU and Intellectual Property Rights. Predominately, it will focus on the enforcement of IPR(s) as an abusive practise of dominance and whether a dominant undertaking has the ability to protect its IPR by refusing to licence its IPR to a third party. The main purpose wi

In July 2011 a new education act came into effect in Sweden. The law consists of, among other things, a paragraph stating that all students must have access to school libraries. After the law was put in place a big debate was started based on differences in the interpretation of the law and different opinions about the role of the school library. The debate has also focused on the big differences

Syftet för undersökningen är att utreda identitet, relationer och gränsdragningar i den döva gruppen under 1954-1970. Detta genom att undersöka en lokal dövförening, Malmö Dövas Förening ”Svenske”. Källmaterialet utgörs huvudsakligen av protokollanteckningar från föreningsstyrelsens sammanträden. Analysen stöttade sig mot teoretiska begrepp hämtade ur deaf studies och disability studies, två forsk

Abstract Following the 2004 EU-enlargement, the UK granted free movements of workers to nationals from the eight new member states (A8). There was a widespread concern in other European countries regarding the expected large inflow of A8 migrants, and consequently twelve of the old EU member states decided to implement transitional restrictions. This lead to a relatively large inflow of A8 migrant

This report deals with flame extinguishment of liquid and solid fuels in an experiment construction widely known as Burner Cup. The fuels are heptan, methanol and PMMA. According to a theory called fire point theory developed by Rasbash also further developed by Beyler the extinguish concentration increasing when applied external flux increases. Experiments have earlier been done by Magee and Rei

I denna uppsats undersöks något helt nytt inom den populära biografifilmen. I Todd Haynes film "I'm Not There" porträtterar sex olika skådespelare sju olika faser i Bob Dylans liv och karriär. Att låta flera aktörer och/eller aktriser spela samma karaktär är ett högst ovanligt drag i filmens värld. Med detta som utgångspunkt görs en analys och diskussion av filmen som förankras i dok

This thesis focuses on the librarian’s professional identity and how this is formed. The purpose of this study is, more specifically, to discover how the professional identity of the research librarians is constructed, and which professional identity positions are avaliable during Book a librarian-meetings at Lund university. By doing this I want to establish an understanding for what Book a libra

This research outlines the evolution of the manufacturing and industrial export structure of countries, Estonia, Lithuania, and Latvia since 1992 within the framework of Economic Complexity and the Product Space. The research reveals a relatively low level of specialization in the countries’ export structures and identifies a dual structure within the economy due to the foreign ownership of firms.

Like many other international human rights law instruments, the 1951 Convention relating to the Status of Refugees was written from a male perspective, which has resulted in that the refugee definition of the Convention historically has been interpreted through a framework of male experiences. For this reason, many asylum claims of female applicants have been ignored. In order to be granted refug

Searching for a possible explanation for the phenotypic heterogeneity in IgG3 deficiency, we studied the antibody response to a polysaccharide and a protein antigen in IgG3-deficient (IgG3d) adults after vaccination with Haemophilus influenzae type b capsular polysaccharide (Hib CP) conjugated to tetanus toxoid. Distribution of isotypes, idiotypes, clonotypes, and Gm allotypes were compared. All t

Cancer prevalence is the proportion of individuals in a population who at some stage during their lifetime have been diagnosed with cancer, irrespective of the date of diagnosis. Cancer prevalence statistics have generally been provided by a limited number of well established cancer registries that have been in existence for several decades. The advent of systematic follow-up of life status of inc

An anti-estradiol antibody with improved specificity is searched for by combining steroid analog binding studies, mutant antibodies obtained from a phage-display library and structural modeling. Three-dimensional models for the anti-estradiol antibody 57-2 were constructed by comparative model building. Estradiol and analogs were docked into the combining site and molecular dynamics simulation was

Rheumatoid arthritis (RA) and multiple sclerosis (MS) are complex inflammatory autoimmune diseases. The aetiology is largely unknown but the risk of developing disease is dependent on both genetic and environmental factors. Extensive efforts have been done to identify the underlying genes in order to understand the molecular mechanisms of the diseases. Until recently, only a few genes have been qu
