Northern inland waters emit CO2 and CH4 to the atmosphere but the importance of these emissions is poorly understood due to a lack of integrated catchment-scale estimates of carbon (C) emissions from lakes and streams. In this study we quantified the annual emission of CO2 and CH4 from 27 lakes and 23 stream segments in a 15km(2) subarctic catchment in northern Sweden. All lakes and streams were n
It remains poorly understood how the hematopoietic stem/progenitor cells (HSPC) are attracted to their niches and the functional consequences of such interaction. In the present study, we show that the cell cycle regulator cyclin A1 in association with vascular endothelial growth factor receptor 1 (VEGFR1), is required for HSPC and their niches to maintain their function and proper interaction. In
Background The aim of the study is to assess the relationship between the shape of plasma glucose concentration during the OGTT and future risk for T2DM. Methods 2445 non-diabetic subjects from the Botnia study received an OGTT at baseline and after 7-8 years of follow-up. Results NGT and IFG subjects who returned their plasma glucose concentration following an ingested glucose load below FPG with
It is generally agreed that traditional alcohol biomarkers lack in sensitivity to detect hazardous alcohol consumption. The present study was undertaken to evaluate the ability of phosphatidylethanol (PEth) and traditional alcohol markers to detect moderate alcohol consumption and to distinguish between moderate alcohol consumption and abstinence.
The difference between evaluatively loaded and evaluatively neutralized fivefactor inventory items was used to create new variables, one for each factor in the fivefactor model. Study 1 showed that these variables can be represented in terms of a general evaluative factor which is related to social desirability measures and indicated that the factor may equally well be represented as separate from
This paper examines the importance of various social factors for the prevalence of "sick building syndrome" (SBS) in residential buildings. A survey has been conducted in Malmö, Sweden, resulting in 1131 randomly selected residents participating in the study (response rate 57 %). Two clusters of social factors were examined: the socio-structural position of the individual and psychosocial aspects
The greatest barrier to successful haemophilia A care in resource-rich countries is the development of inhibitors to therapeutic factor VIII. Children with inhibitors suffer through increased bleeding and joint damage as well as frequent venepuncture. Costs associated with inhibitors are beyond many healthcare systems. Over the last two decades, there has been no improvement in our ability to redu
Chemotherapy is often used before a resection for colorectal liver metastases. After chemotherapy, metastases may disappear on cross-sectional imaging but residual metastatic disease may still exist. The aim of this retrospective study was to investigate the impact of new advancements in imaging technology such as magnetic resonance imaging (MRI) with liver-specific contrast (Gd-EOB-DTPA) and cont
Background: The L68Q variant of cystatin C is highly amyloidogenic forming aggregates in individuals with HCCAA. Results: Spermatozoa from mice expressing human L68Q cystatin C exhibit fertility defects and increased levels of amyloid. Conclusion: L68Q epididymal fluid containing cystatin C amyloid is harmful for sperm function. Significance: Amyloid in the reproductive tract may contribute to mal
We present temperature dependent electrical measurements on n-type InAs/InSb nanowire heterostructure field-effect transistors. The barrier height of the heterostructure junction is determined to be 220 meV, indicating a broken bandgap alignment. A clear asymmetry is observed when applying a bias to either the InAs or the InSb side of the junction. Impact ionization and band-to-band tunneling is m
Prenatal exposure to phthalates is suggested to negatively impact male reproductive function, but human data are lacking.
Hepatitis C virus (HCV) infection is a frequent problem in hemodialysis units. The prevalence and incidence of HCV infection over a decade were studied in a nephrology unit affected by previous nosocomial HCV transmission. The HCV non-structural 5B protein gene was sequenced to achieve phylogenetic analysis of a new (incident) case of infection. Proportions of patients who were and were not infect
Contingency planning is widely considered to be an essential role of public authorities. Anticipation of what may happen, coupled with the prior allocation of resources, personnel, equipment, crisis control rooms, tasks, responsibilities and decision guidance/rules, is assumed to maximise the chances of a successful response in the event of a crisis. However, this paper proposes that the relations
Even though there has been a rapid development in instrumentation and applications of supercritical fluid chromatography (SFC), relatively little is known about retention mechanisms compared to high-performance liquid chromatography (HPLC). Much effort has been made to characterize the influence of injection solvents on chromatographic efficiency in HPLC, however has been left rather uninvestigate
Male breast cancer is poorly understood with a large proportion arising in the familial context particularly with the BRCA2 germline mutation. As phenotypic and genotypic differences between sporadic and familial male breast cancers have been noted, we investigated the importance of a hypoxic drive in these cancers as this pathway has been shown to be of importance in familial female breast cancer
Pore condensation followed by polymerization is proposed as an explanatory model of several observations reported in the literature regarding the dehydration of glycerol to acrolein. The major conclusion is that glycerol pore condensation in the micro- and mesopores, followed by polymerization in the pores, play a role in catalyst deactivation.
Software Process Improvement (SPI) encompasses the analysis and modification of the processes within software development, aimed at improving key areas that contribute to the organizations' goals. The task of evaluating whether the selected improvement path meets these goals is challenging. On the basis of the results of a systematic literature review on SPI measurement and evaluation practices, w
Perfluorinated compounds (PFCs), such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), are used in large quantities. They are persistent and found in measurable levels in human serum around the world. They have been associated with developmental, hepatic, and carcinogenic effects in animal studies. The aim of the present study was to describe levels of PFCs in serum among Inu
