José Asunción Silva is a Colombian poet most known for having renewed the metrics in Spanish poetry during the 19th century. José Asunción Silva’s only novel, De sobremesa 1887-1896 [After dinner, 1887-1896] written in 1896 is a significant and representative modernist novel in the tradition of Latin-American modernismo. Silva’s novel has been considered as a structureless, narratively disordered

A role for regulatory lymphocytes has been demonstrated in the pathogenesis of type I diabetes in the NOD mouse but the nature of these cells is debated. CD1d-restricted NKT lymphocytes have been implicated in this process. Previous reports of reduced diabetes incidence in NOD mice in which the numbers of NKT cells are artificially increased have been attributed to the enhanced production of IL-4

This thesis is focused on natural killer (NK) T cells. NKT cells recognize lipids and glycolipids, rather than peptides, in the contents of the antigen presenting molecule CD1d. NKT cells have a surface phenotype reminiscent of memory cells, and have been shown to rapidly produce large amounts of cytokines, such as IL-4 and IFN-gamma, upon activation. Because of their rapid response to activation,

Health-health analysis (HHA) focuses on statistical lives themselves as a numeraire. The underlying principle is that the expected gains in health and safety of reduced risks in one area may result in increasing risks somewhere else in society. By reducing one risk other risks may increase due to changed individual behaviour. In addition to this direct effect, another indirect effect will also be

Dwarf eggs, e.g. eggs that are very much smaller than normal eggs, are occasionally found among normal eggs in nests of birds. Although they are not often mentioned in the handbooks, the frequency of dwarf eggs seems to be about one per thousand, or less. In 2001 I found one dwarf egg in a nest with two eggs of the Long-tailed Skua Stercorarius longicaudus at Ammarnas in Swedish Lapland. I did not

The neuropeptide gastrin releasing peptide (GRP) stimulates insulin secretion and induces oscillations of the cytoplasmic Ca(2+) concentration ([Ca(2+)](cyt)) in clonal insulinoma cells. It is not known whether GRP affects [Ca(2+)](cyt) in normal beta cells. We investigated, in single, normal, mouse islet beta cells, the effects of GRP on [Ca(2+)](cyt), by dual wavelength spectrophotofluorometry.

Objectives: To examine if obesity status and socio-economic and lifestyle factors are associated with self-reported past food habit change, and also whether the level of obesity depends on the reason for change. Design: Cross-sectional analysis within the Malmo Diet and Cancer (MDC) study using data from the baseline examination and the extensive socio-economic and lifestyle questionnaire includin

An amino-terminal region of a, chain of type IV collagen noncollagenous domain [alpha(3)(IV)NC1] that induces experimental autoimmune glomerulortephritis (EAG) in rats has been identified. Only recombinant antigens that contain a nine-amino acid (AA) span of alpha(3)(IV)NC1, consistent with a T cell epitope, could induce EAG. It was hypothesized that synthetic peptides of this region should induce

We analysed the presence of hepatitis C virus (HCV) antibodies in 566 patients undergoing liver biopsy. While over 20% of the patients were anti-HCV positive according to ELISA, only 13.8% had HCV antibodies when tested with a four-antigen recombinant immunoblot assay (RIBA 2). At the time of inclusion in the study, most patients were asymptomatic, irrespective of whether they were HCV-positive. H

Simultaneous OH- and formaldehyde planar-LIF measurements have been performed in an optical engine using two laser sources working on 283 and 355 nm, respectively. The engine used for the measurements was a car diesel engine converted to single-cylinder operation and modified for optical access. The fuel, n-heptane, was injected by a direct injection common-rail system and the engine was also fitt

Ethical issues arise in obstetric situations and demand the obstetrician’s moral consideration for those who are involved in the actual case (Paper I). A balance between the health of the foetus and the autonomy of the woman is necessary to do the best for both the mother and her foetus/infant. Preterm birth is one of the main causes of mortality and morbidity for the child, in short and long term

The main objective of Task 23 Small Scale Reformers for On-site Hydrogen Supply has been to provide a basis for harmonization of technology for on-site hydrogen production from hydrocarbon s– fossil and renewable. The four sub-objectives were to: • Develop a basis for harmonized capacities for the on-site hydrogen reformer unit • Identify and examine issues related to the promotion of widespread u

Dynamic characterization of elastomers, i.e. laboratory testing and fitting of constitutive models, is quite complicated. The demands on the laboratory equipment and the skill of the personal handling the test equipment are high. Stationary harmonic testing is an established method for evaluating dynamic properties of elastomers. However, it is demanding experimentally when it comes to high freque

The immune system is an important part of the physiology of higher organisms. In the immune system antibodies play a key role in neutralizing and clearing potentially lethal threats from the environment. The importance of antibodies in the immune system has made them come to the attention as a tool in chemistry and medicine. This thesis, which is based on four original papers, deal with antibody d

Swedish Red (SR) dairy cattle is the second most common breed in Sweden and hence SR milk quality is crucial for the nutritional value and the processability of the milk delivered to the Swedish dairies. This thesis will give an insight into the quality of milk from SR cows and it will illuminate the possibilities for improvements of both breeding programs and the quality of different dairy produc
