Phenotypic and functional analysis of the mesenchymal stromal cell compartment in the thymus

T cells are key cellular components of the adaptive immune system that play a critical role in our defense against pathogens and cancer but also contribute to pathology in the setting of chronic inflammation and autoimmunity. The thymus constitutes the body's major T cell production site, where bone marrow-derived progenitors migrate in a co-ordinated fashion through anatomically distinct cortical

Governance approaches that can be used to implement sustainability criteria

Implementation of sustainability criteria, both in legal frameworks and voluntary sustainability standards, is an urgent and important issue. In the article, three less state-centric governance approaches and their capacity to be used to implement sustainability criteria have been investigated. The chosen approaches are good governance, multi-level governance and selfgovernance. Their potential st

Genetic variants on chromosome 5p12 are associated with risk of breast cancer in African American women: the Black Women's Health Study

Two single nucleotide polymorphisms (SNPs), rs4415084, and rs10941679 on chromosome 5p12 were associated with risk of breast cancer in a recent genome-wide association study (GWAS) of women of European ancestry. Both SNPs are located in a large high-LD region and the causal variant(s) are still unknown. We conducted a nested case-control study in a cohort of African American women to replicate and

Stroke genetics: a review and update.

Stroke genetics includes several topics of clinical interest, including (1) molecular genetic variations affecting risk of monogenic stroke syndromes; (2) molecular genetic variations affecting risk of common stroke syndromes, sometimes with specific effects on risk of specific main types of stroke or subtypes of ischemic and hemorrhagic stroke; (3) genetics of conditions associated with stroke ri

The Realism in Older People's Confidence Judgments of Answers to General Knowledge Questions

The study investigated 2 aspects of the accuracy (i.e., realism) of confidence judgments of persons age 60-93 years (N = 1,384) regarding their answers to general knowledge questions. These aspects are the level of confidence (calibration) in relation to the proportion of correct answers and the ability to discriminate between correct and incorrect answers by means of confidence judgments. No age

Energy Analysis for Graphics Processors using Novel Methods & Efficient Multi-View Rendering

Real-time rendering is increasingly being performed on battery powered devices, such as laptops and mobile phones. As a result, performance in rendering time is not the only important factor, but the energy consumption is also becoming more and more important, as a lower energy usage directly translates to longer battery time. The main topic of this thesis is energy consumption of graphics process

SO2-catalysed steam pretreatment of quinoa stalks

BACKGROUNDQuinoa is a pseudo-cereal grown predominantly in South America. The quinoa stalks are lignocellulosic residues, which have a limited use today. The objective of the current study was to assess the potential of this material as a source of monosaccharides for fermentation purposes by means of steam pretreatment giving sugars from the hemicellulose part, and enzymatic hydrolysis of the sol

What happened to our features? visualization and understanding of scope change dynamics in a large-scale industrial setting

When developing software platforms for product lines, decisions on which features to implement are affected by factors such as changing markets and evolving technologies. Effective scoping thus requires continuous assessment of how changes in the domain impact scoping decisions. Decisions may have to be changed as circumstances change, resulting in a dynamic evolution of the scope of software asse

Determinants of stimulated peripheral blood cytokine production among farming women

Farming environment and environmental exposure to microbial agents have been suggested to promote favorable development of immune system in children and protect against allergic diseases. However, effects of farm exposure on adult immune responses are less clear. Aim of the present study was to examine associations of farm related factors and measured microbial exposure with stimulated production

Evaluation of traffic safety, based on micro-level behavioural data: theoretical framework and first implementation.

A traffic encounter between individual road users is a process of continuous interplay over time and space and may be seen as an elementary event with the potential to develop into an accident. This paper proposes a framework for organising all traffic encounters into a severity hierarchy based on some operational severity measure. A severity hierarchy provides a description of the safety situatio

Cash-Flow-at-Risk and Debt Capacity

Cash Flow-at-Risk (CFaR) is a risk measure that conveys information on the shortfall in cash flow, associated with a certain probability, a firm could experience over a certain time period. However, to provide information on outcomes that are identified as costly by the risk management literature, in particular underinvestment due to financing constraints, a risk measure needs to make explicit ref

Lead concentration in plasma as a biomarker of exposure and risk, and modification of toxicity by delta-aminolevulinic acid dehydratase gene polymorphism

Blood lead concentration (B-Pb), the main biomarker of lead exposure and risk, is curvi-linearily related to exposure. We assessed plasma lead (P-Pb) as a marker for both lead exposure and toxic effects. We examined claims that delta-aminolevulinic acid dehydratase genotype (ALAD) can modify lead toxicity. In 290 lead-exposed and 91 unexposed Chinese workers, we determined P-Pb, B-Pb, urinary lead

Evaluation of image quality and diagnostic accuracy in breast tomosynthesis. Comparison with digital mammography and estimates of radiation risk

Recent advances in the digital detector technology have paved the way for modalities such as two-dimensional digital mammography (DM) and three-dimensional breast tomosynthesis (BT). In this work, experimental studies were conducted to investigate the influence of reducing the average glandular dose (AGD) on detection of simulated lesions in DM and to compare the diagnostic accuracy of BT and DM.

No Excess Risks in Offspring With Paternal Preconception Exposure to Disease-Modifying Antirheumatic Drugs

Objective. To examine pregnancy outcomes in the partners of male patients with inflammatory joint disease who were or were not exposed to disease-modifying antirheumatic drugs (DMARDs) before conception compared with the outcomes in reference subjects from the general population. Methods. Linkage of data from a longitudinal observational study of patients with inflammatory joint disease (the Norwe

Effect of Complement on HIV-2 Plasma Antiviral Activity Is Intratype Specific and Potent

Human immunodeficiency virus type-2 (HIV-2) infected individuals develop immunodeficiency with a considerable delay and transmit the virus at a lower rate as compared to HIV-1 infected. Conceivably, comparative studies on immune responsiveness of the HIV-1 and HIV-2 infected hosts may help to explain differences in pathogenesis and transmission between the two types of infection. Previous studies
