Aging causes profound effects on the hematopoietic stem cell (HSC) pool, including an altered output of mature progeny and enhanced self-propagation of repopulating-defective HSCs. An important outstanding question is whether HSCs can be protected from aging. The signal adaptor protein LNK negatively regulates hematopoiesis at several cellular stages. It has remained unclear how the enhanced sensi

We show that the blockage in transmission of a screen with a periodic microstructure integrated over all wavelengths is bounded by the static polarizability per unit area of the screen. Physical bounds on the co-polarized transmission coefficient over a wavelength interval are presented using only information from the zero-frequency properties of the microstructure. The theoretical results are com

Background Medical adherence is important in the treatment of depression. Primary medical adherence, i.e. patients collecting their newly prescribed medications from pharmacies, is very different depending on the drug prescribed Objective To assess the rate of primary medical adherence in patients prescribed antidepressants and to identify characteristics that make patients less likely to pick up

Aim To investigate public health nurses' perceptions and experiences of mental health and of the prevention of mental ill health among women postpartum, within paediatric healthcare services.

This thesis investigates the relationship between eye movements, mental imagery and memory retrieval in four studies based on eye-tracking experiments. The first study is an investigation of eye movements during mental imagery elicited both visually and verbally. The use of complex stimuli and the development of a novel method where eye movements are recorded concurrently with verbal data enabled

In order to advance the understanding of which types of regional innovation system represent effective innovation support for what kinds of industry in different regions analyses must be contextualised by reference to the actual knowledge base of various industries as well as to the regional and national institutional framework, which strongly shape the innovation processes of firms. Of special im

Tobacco use is one of the major risk factors of cardiovascular disease. The underlying molecular mechanisms that link cigarette smoke to cardiovascular disease remain unclear. The present study was designed to examine the effects of dimethyl sulfoxide (DMSO)-soluble smoke particles (DSPs) on human aortic smooth muscle cell (HASMC) cultures, and to explore the mitogen-activated protein kinase (MAPK

Mucosal surfaces of the reproductive tract as well as their secretions have important roles in preventing sexual transmission of HIV-1. In the current study, the majority of the intrinsic anti-HIV-1 activity of human seminal plasma (SP) was determined to reside in the cationic polypeptide fraction. Antiviral assays utilizing luciferase reporter cells and lymphocytic cells revealed the ability of w

The aim of the article is to discuss the interpretation of the Romanesque round church towers in Scandinavia. The article focuses on the 15-19 churches with round towers in medieval Denmark, Sweden and Norway, with the main part in Southern Schleswig and Scania; none are known from Finland. The chronology and social context, function and meaning of the church towers are discussed. Finally a list o

We present a computational tool to develop an exhaust gas recirculation (EGR) - air-fuel ratio (AFR) operating range for homogeneous charge compression ignition (HCCI) engines. A single- cylinder Ricardo E-6 engine running in HCCI mode, with external EGR is simulated using an improved probability density function (PDF)-based engine cycle model. For a base case, the in-cylinder temperature and unbu

What exactly are opinions? What does it mean to express an attitude? Given the ubiquitous use of surveys, polls and rating scales, it seems we ought to have firm answers to these fundamental questions, but we do not. Here we present a novel approach to investigate the nature of attitudes. We created a self-transforming paper survey of moral opinions, covering both foundational principles, and curr

We have addressed the importance of B cell tolerance to collagen type II, a matrix protein, which is a target in rheumatoid arthritis (RA) and its mouse models. We generated a germline-encoded anti-collagen type II (CII) IgH replacement anti-C1 B cell mouse strain (ACB) to investigate how B cell tolerance to CII, a matrix protein, is subverted and to further understand pathogenesis of RA. Phenotyp

There are two interpretations of rhetoric that are backed by a long tradition: as the theory of argumentation and persuasion, which is how it was born in Antiquity, and as the taxonomy of rhetorical figures, which is the form in which it reigned supreme from the 16th century onwards. In both of these senses, advertising discourse today is the favoured, and in fact almost exclusive, domain of rheto

This dissertation uses longitudinal micro-data from Stockholm between 1878 and 1926 to study the causes and consequences of the fertility transition and to examine the development of living standards inequality during industrialization. Although both processes have received much interest from researchers, we know relatively little of how either one played out among individuals in urban areas, whic
