Nematophagous fungi are parasites of nematodes, thus they have been considered and tested for biological control of parasitic nematodes, but so far with limited success. Due to the fact that the nematode cuticle is composed of proteins it is likely that fungal extracellular proteases are involved in the infection of nematodes. I have isolated a gene (designated PII) encoding an extracellular cutic
Popular Abstract in Swedish Grupp B streptokocker (GBS) är den vanligaste orsaken till blodförgiftning, lunginflammation och hjärnhinneinflammation i nyföddhetsperioden. Ungefär en fjärdedel av alla kvinnor är koloniserade (bärare) genitalt av GBS under graviditeten och förlossningen. Hälften av barnen till dessa kvinnor blir smittade av bakterien i samband med födseln, men bara en liten del av deInfection with group B streptococcus (GBS), an encapsulated bacterium, is an important cause of neonatal morbidity and mortality. Capsular polysaccharides and cell surface proteins of GBS are candidate antigens for development of a human GBS vaccine. Proteins have many advantages as vaccine antigens. The majority of the neonatal infections are caused by strains of capsular serotypes Ia, Ib, II, II
Objectives: A potential role in cancer biology is suggested for YKL-40 (CHI3L1, HC gp-39). The purpose of this study was to evaluate the clinical value of serum YKL-40 (sYKL-40) in multiple myeloma (MM) and to examine YKL-40 expression in malignant plasma cells (MM PCs). Methods: sYKL-40 was measured by enzyme-linked immunosorbent assay (ELISA) in 82 patients with newly diagnosed MM. YKL-40 expres
Mating behaviour and mating patterns are affected to a large extent by body size in both hermaphrodites and gonochorists. Detailed research on mating patterns, mate choice, pre- and post-copulatory sexual selection in marine pulmonates is wanting, thus warranting more attention as a study system in the future. The simultaneous hermaphroditic limpet Siphonaria capensis (Pulmonata: Basommatophora) s
Mental health problems among adolescents have become a major public health issue, and it is therefore important to increase knowledge on the contextual determinants of adolescent mental health. One such determinant is the socioeconomic structure of the neighbourhood. The present study has two central objectives, (i) to examine if neighbourhood socioeconomic deprivation is associated to individual
The rapidly growing collection of diverse genome-scale data from multiple tumor types sheds light on various aspects of the underlying tumor biology. With the objective to identify genes of importance for breast tumorigenesis in men and to enable comparisons with genes important for breast cancer development in women, we applied the computational framework COpy Number and EXpression In Cancer (CON
Popular Abstract in Swedish I plan to add a summary in Swedish at the WWW-page www.biokem.lu.se/education/theses/johannordthesis.htmRecombinant dUTPase from the bacterium Escherichia coli, the retrovirus equine infectious anemia virus (EIAV) and Homo sapiens have been made available for physico-chemical characterisation. The protocols developed have also proven to be suitable for production of enzymes modified by isotope labelling or other methods. The improved accessibility of enzyme material has enabled the subsequent invest
Recent advances in laser technology, with the development of extremely short-pulse, high-intensity lasers, have opened doors to new areas in atomic physics. By focusing light from an intense, short-pulse laser into a gas jet, the emission of high-order harmonics of the laser frequency has been studied. The aim of this work has been two-fold: to better understand the underlying physics of the harmo
Popular Abstract in Swedish Hjärt-kärlsjukdomar är en ledande orsak av sjuklighet och dödlighet. Med hjälp av dagens moderna ultraljudsteknik är det möjligt att påvisa även begynnande, mycket diskreta kärlförändringar. En tidig upptäckt av dessa kan bli av betydelse för individens framtida hälsa. I ett antal studier har vi med hjälp av ultraljud undersökt kärlens styvhet och förmåga att vidgas (enCardiovascular disease (CVD) is one of the leading causes of mortality and morbidity. Early recognition of vascular changes, both structural and functional, may help to identify individuals at risk for CVD. Using modern ultrasound techniques – the echo-tracking technique for assessment of stiffness in large arteries and flow-mediated dilatation of the brachial artery as an indicator of endothelial
Aim This study investigates inter-annual variability in burnt area in southern Africa and the extent to which climate is responsible for this variation. We compare data from long-term field sites across the region with remotely sensed burnt area data to test whether it is possible to develop a general model. Location Africa south of the equator. Methods Linear mixed effects models were used to det
Objectives: Short relative telomere length (RTL) is associated with vascular ageing, inflammation and cardiovascular risk factors. Previous studies have reported an association between abdominal aortic aneurysm and short RTL. The presence of atherosclerosis among patients with aneurysm disease may, however, be a confounder. The aim was to explore the associations between short RTL and aneurysm dis
The exocrine pancreatic insufficient (EPI) pigs grow less due to different disturbances in feed digestion, absorption, and retention. Use of pancreatic-like enzymes of microbial origin in pigs may improve feed use and performance in slow-growing pigs. The aim was to study gut recovery and effectiveness of pancreatic-like enzymes of microbial origin supplementation on pig performance. Six male pigs
One of the largest sources of uncertainties in modelling of the future global climate is the response of the terrestrial carbon cycle. Studies have shown that it is likely that the extant land sink of carbon will weaken in a warming climate. Should this happen, a larger portion of the annual carbon dioxide emissions will remain in the atmosphere, and further increase global warming, which in turn
From a nursing perspective it is important to have information about the type of care needed, the reasons care is needed and quality of life among the most elderly people living in their own homes, in order to support their independence and maximise their quality of life. Thus a study was performed to investigate people aged 75 years and older dependent on care from professionals and/or a next of
OBJECTIVE-Latent autoimmune diabetes in adults (LADA) is often considered a slowly progressing subtype of type 1 diabetes, although the clinical picture more resembles type 2 diabetes. One way to improve classification is to study whether LADA shares genetic features with type 1 and/or type 2 diabetes. RESEARCH DESIGN AND METHODS-To accomplish this we studied whether LADA shares variation in the H
To elucidate how diabetic patients with limb-threatening foot lesions perceive and evaluate content and organisation of treatment in a multi-place hyperbaric oxygen chamber. To our knowledge there are no patients' evaluations of diabetes care in a high-technology area like the hyperbaric oxygen chamber. The burden on persons with diabetic foot complications might be increased if adjuvant therapy w
The DNA ploidy level of 673 accessions belonging to 238 species of Hieracium have been analyzed by flow cytometry. 222 of the species were of Scandinavian origin as members of the exclusively apomictic H. sectt. Bifida, Hieracium, Oreadea, Tridentata and Vulgata. For the overwhelming majority of the species, the ploidy level (or chromosme number) has never been investigated before. Approximately 5
One of the central bones of contention in the study of the European Union (EU) is the capacity of its supranational institutions to be a driving force in the process toward deeper integration. Whereas existing research predominantly addresses the institutions’ ability to shape European integration through pre-decisional agenda-setting, this study examines the scope for supranational influence in t
After the discovery of space masers based on OH radicals (Weaver et al.cite{Wea65}) and H2O (Cheung et al. cite{Che69}) such microwavelasers have been found to work in more than 100 molecular species(Elitzur cite{Eli92}; Townes cite{Tow97}), as well as in highlyexcited H atoms (Strelnitski et al. cite{Str96}). In the IR region (10mum), the effect of stimulated emission of radiation in t
