Background: The US Environmental Protection Agency voluntary phased-out residential use of chlorpyrifos in 2001. In contrast, in Costa Rica, chlorpyrifos-treated bags are increasingly used to protect banana and plantain fruits from insects and to fulfill product standards, even in populated areas. Objectives: To evaluate children's exposure to chlorpyrifos in villages situated nearby banana planta

I investigated the bacterial utilization of terrestrially derived dissolved organic nitrogen (DON) in aquatic ecosystems, and assessed the potential role of river-born DON in marine eutrophication. To determine the bioavailability of DON, I developed a bioassay employing N-limited bacterial regrowth cultures, which were calibrated with additions of inorganic nitrogen. I found that between 2 and 72

This thesis is concerned primarily with peptide and protein partitioning in aqueous two-phase systems and the connection between partitioning behavior and protein structure. The surface properties of a protein is often crucial for recognition and interaction with other molecules. Important functional residues can be identified by mutational analysis. There is a need for rapid methods to study prot

Households base their choices of heating systems on subjectively dependent conceptions of heating sources, rather than on an understanding of a complex reality. Similar to other agents in society, households need to construct simplified frames to be able to make their choices possible to manage. Using in-depth interviews with households in Småland (in Sweden) with a few comparisons from Massachuse

The effect of three different nitrogen sources on the growth of external ectomycorrhizal mycelium was studied in Perspex micorocosms. Nonsterile peat was used as substrate. Five different fungal isolates growing in symbiosis with pine seedlings were investigated: two isolates of Paxillus involutus, one of Suillus bovinus and two unidentified ectomycorrhizal fungi isolated from ectomycorrhizal root

BACKGROUND: Pulmonary embolism (PE) is a severe condition with nonspecific symptoms. Diagnosis relies on medical imaging but follow-up is currently based on clinical symptoms and general risk factors. The duration of anticoagulant treatment after an acute episode of PE is still subject to debate and the best method of identifying the risk of recurrence in individual patients is undefined. Tomograp

Popular Abstract in Swedish Bakgrund I Sverige erbjuds samtliga gravida kvinnor ett rutinultraljud vid 18-20 graviditetsveckor. Syftet med undersökningen är att fastställa antalet foster, uppskatta graviditetslängd samt granska fosteranatomin för att upptäcka eventuella missbildningar. En del missbildningar kan man se med ultraljud, men långtifrån alla. Att redan under graviditeten känna till om The aim was to evaluate first trimester nuchal translucency (NT) measurement for detection and risk assessment of fetal malformations and fetal loss. 39 572 pregnant women were randomised to either a routine ultrasound scan at 12-14 weeks including NT measurement or to a routine scan at 18-20 weeks. Prenatal diagnosis of major congenital heart malformations was compared between the two groups. In

An aqueous system containing fluorapatite (Ca-5(PO4)(3)F), (FAP) and varying amounts of goethite (alpha-FeOOH) has been investigated. Batch experiments and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy were used to monitor the dissolution products of FAP, as well as the adsorption, and phase transformation of phosphate at the goethite surface over a period of 129

The five ribosomal P-proteins, denoted P0-(P1-P2)(2), constitute the stalk structure of the large subunit of eukaryotic ribosomes. In the yeast Saccharomyces cerevisiae, the group of P1 and P2 proteins is differentiated into subgroups that form two separate P1A-P2B and P1B-P2A heterodimers on the stalk. So far, structural studies on the P-proteins have not yielded any satisfactory information usin

BACKGROUND. Radiotherapy is a known risk factor for sarcoma development. Postirradiation sarcomas arise within the radiation field after a latency period of several years and usually are highly malignant. Very little is yet known about their genetic changes. METHODS. Twenty-seven postirradiation sarcomas were analyzed by comparative genomic hybridization, which allows genome-wide screening of DNA

Popular Abstract in Swedish Uppskattningsvis 140–180 000 patienter i Sverige har förmaksflimmer. Den totala förekomsten är dock okänd eftersom vissa patienter också helt saknar symtom och därför inte har kännedom om sin sjukdom. Förmaksflimmer, som både kan vara kroniskt eller komma i attacker, innebär att förmaken inte aktivt pumpar ner blodet i hjärtats kammare. Istället sker mer okoordinerade sBackground: Oral antigoagulation treatment (OAT) with warfarin have a narrow therapeutic window and patients exhibit a highly variable doseresponse that is attributable to genetic, disease-related,and environmental factors as well as prescription and nonprescription drugs, dietary vitamin K and alcohol. The effect of warfarin treatement on blood coagulation is measured using international normaliz

Background: Risk factors for rare gynecological cancers are largely unknown. Initial research has indicated that the metabolic syndrome (MetS) or individual components could play a role. Materials and methods: The Metabolic syndrome and Cancer project cohort includes 288 834 women. During an average follow-up of 11 years, 82 vulvar, 26 vaginal and 43 other rare gynecological cancers were identifie

Background: The prevalence of blindness and visual impairment from glaucoma is influenced by the criteria used to define these entities, which differ between countries and regions, as well as among published reports. The objective of the present study was to ascertain the extent to which different criteria of blindness and visual impairment influence estimates of the number of patients classified

The present study investigated whether the effects of central cholinergic stimulation on thermoregulation during exercise are modulated by arterial baroreceptors. Wistar rats were submitted to sinoaortic denervation (SAD) or sham denervation (SHAM) and then fitted with a chronic guide cannula into the lateral cerebral ventricle. After 2 weeks, a catheter was implanted into the ascending aorta, and

Objectives To assess 2-year durability of joint contracture correction following collagenase injections for Dupuytren's disease. Design Prospective cohort study. Setting Orthopaedic Department in Sweden. Participants Patients with palpable Dupuytren's cord and active extension deficit (AED) ≥30° in the metacarpophalangeal (MCP) and/or proximal interphalangeal (PIP) joint. A surgeon injected 0.80 m

Both genetic and lifestyle factors contribute to the risk of non-alcoholic steatohepatitis (NASH). Additionally, epigenetic modifications may also play a key role in the pathogenesis of NASH. We therefore investigated liver DNA methylation, as a marker for epigenetic alterations, in individuals with simple steatosis and NASH, and further tested if these alterations were associated with clinical ph

Background: Patients with unprovoked first venous thromboembolism (VTE) are at a high risk of recurrence. Although circulating microRNAs (miRNAs) have been found to be associated with VTE and are markers of hypercoagulability, this study is the first to examine whether circulating miRNAs are associated with the risk of VTE recurrence. Results: A nested case-control study design was used where plas

To investigate the genetic identities of the mucins secreted in cystic fibrosis (CF) airways, sputum was collected from five individuals. Samples were separated into gel and sol phases by high-speed centrifugation and the gel phase was extracted in 6 M guanidinium chloride. The 'insoluble' residue remaining after extraction of the gel phase was brought into solution by reduction/alkylation. Densit
