Background: The expected reduction in cervical cancer incidence as a result of increased access to antiretroviral therapy is yet to be seen. In this study we investigated the effect of HIV infection and treatment on high-risk (hr) human papilloma virus (HPV) prevalence and distribution. Methods: Cervical cells from 515 (220 HIV positive and 295 HIV negative) women, recruited during community cervi

Background: Case-control studies suggested a moderate, but consistent, association of hepatitis C virus (HCV) infection with lymphoid tissue malignancies, especially non-Hodgkin lymphoma (NHL). More limited data suggested that hepatitis B virus (HBV) infection might also be associated with NHL. However, prospective studies on the topic are few. Methods: A nested case-control study was conducted in

High-dimensional datasets can be confounded by variation from technical sources, such as batches. Undetected batch effects can have severe consequences for the validity of a study's conclusion(s). We evaluate high-throughput RNAseq and miRNAseq as well as DNA methylation and gene expression microarray datasets, mainly from the Cancer Genome Atlas (TCGA) project, in respect to technical and biologi

Pheromone-based monitoring could be a very efficient method to assess the conservation status of rare and elusive insect species, but there are still few studies for which pheromone traps have been used to obtain information on presence, abundance, phenology and movements of such insects. We performed a mark-recapture study of two threatened saproxylic beetles, Osmoderma eremita (Scarabaeidae) and

Ecosystem governance becomes gradually more relevant for a set of companies or actors characterized by symbiotic relations evolved on the top of a technological platform, i.e. a software ecosystem. In this study, we focus on the governance of a hardware-dependent software ecosystem. More specifically, we evaluate the governance model applied by Axis, a network video and surveillance camera produce

The effects of chocolate shell particle size were investigated by means of its influence on rate of oil migration and fat bloom development. The particle size of the non-fat particles in the chocolate, i.e. sugar and cocoa particles was varied between 15, 22 and 40 mu m. A novel set of analytical techniques was used and by combining migration results with surface topology results clear differences

In this study the effects of degree of homogenization and concentration of insoluble material on the perceived texture of apple, tomato, potato pulp and carrot fiber suspensions have been investigated. This was done using a descriptive sensory analysis with the attributes melting, slippery, crispy, grainy and thick. The texture attributes were then correlated to the physicochemical properties of t

We have investigated the possibility of using the 2.45 GHz ISM band for communication between binaural hearing aids. The small size of a modern hearing aid makes it necessary to miniaturize the antennas to make this feasible. Two different types of hearing aid placements have been investigated: in the outer ear and in the ear canal. Both put strict demands on the size of the antenna, which have be

Background: Recruitment is one of the most serious challenges in performing randomized controlled trials. Often clinical trials with participants diagnosed with schizophrenia are terminated prematurely because of recruitment challenges resulting in a considerable waste of resources in the form of time, funding, and the participants' efforts. Dropout rates in schizophrenia trials are also high. Rec

Here we present results from a field experiment in an Arctic wetland situated in Zackenberg, NE Greenland. During one growing season we investigated how dominance of the sedge Eriophorum scheuchzeri affected the below-ground concentrations of low molecular weight carbon compounds (LMWOC) and the fluxes of CO2 and CH4 in comparison to dominance of other sedges (Carex stans and Dupontia psilosantha)

Fleischer behandlar utförligt i bokens tio kapitel frågan om huruvida, när och varför musiker och skivbolag tillskrivs rätten till finansiell ersättning när medier som grammofon, radio och cd gör det möjligt att distribuera och framföra musik som en vara oberoende av ett live-uppförande.

Background: Musculoskeletal disorders are a major burden on individuals, health systems and social care systems and rehabilitation efforts in these disorders are considerable. Self-care is often considered a cost effective treatment alternative owing to limited health care resources. But what are the expectations and attitudes in this question in the general population? The purpose of this study w

Precision hard turning is an emerging innovated machining technology for machining hardened workpiece (60 similar to 62 HRC) with characteristic of better flexibility, high production rate, and cost saving. However, one of problem in this process is that it is difficult to remove the thermal distortion of the workpiece induced by the heat generated during the process, especially in the case of pre

The purpose of this thesis is to explore discourses of insecurity, vulnerability and conflict in Thailand’s Deep South. In order to understand how such discourses are shaped by gender ideologies, the study examines how ideas about men and women are articulated, reproduced and challenged in Thai civil society. Special attention is given to the ways in which men and masculinity are constructed withi

Phosphorylation-dependent movement of the light-harvesting complex II (LHCII) between photosystern II (PSII) and photosystem I (PSI) takes place in order to balance the function of the two photosystems. Traditionally, the phosphorylatable fraction of LHCII has been considered as the functional unit of this dynamic regulation. Here, a mechanical fractionation of the thylakoid membrane of Spinacia o

Popular Abstract in Swedish De flesta cancerpatienter dör på grund av spridning av tumörceller till olika organ. Invasiv och metastaserande cancer svarar ofta inte på behandling och blir då i många fall dödlig. Leukemi är en elakartad sjukdom av blodceller, som påverkar blod-producerande organ. Den höga förekomsten av leukemi förekommer i äldre befolkningen och hos barn. Leukemi återfall och resiThe majority of current treatments used for treatment of prostate cancer (PCa) and leukemia are often limited to a narrow subsets of treated patients. As such, there still remains a significant scope for gaining deeper understanding of molecular mechanisms underlying cancer metastasis for improvement of targeted treatment. Elevated expression of a cell cycle regulator cyclin A1 initiated leukemia
