Consumption of nuts and seeds and pancreatic ductal adenocarcinoma risk in the European Prospective Investigation into Cancer and Nutrition

Four epidemiologic studies have assessed the association between nut intake and pancreatic cancer risk with contradictory results. The present study aims to investigate the relation between nut intake (including seeds) and pancreatic ductal adenocarcinoma (PDAC) risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Cox proportional hazards models were used to estim

Nanowires for Cell Research

This study explores the interaction between living biological cells and semiconductor nanowires. Biological cells are highly complex and dynamic entities, every one of them with individual characteristics and a high degree of internal and external communication. They respond to and affect their external environment with a huge web of fine-tuned control systems. Traditional biochemical tools for

Clause-final subjects in English and Scandinavian

In English and in Scandinavian, presentational expletive constructions with clause-final subjects can be derived by moving the subject to a Spec position in the C-domain, and then raising the remainder of the clause across the subject to an even higher position. The discourse properties of the clause-final subjects then follow without further stipulations. Moreover, the view that the clause-final

Laparoscopic or Open Antireflux Surgery - A Comparative Study with Special Reference to the Patient's Perspective

The overall aim of this thesis was to compare the effects of laparoscopic versus open antireflux surgery in a randomized clinical trial focusing the patients' subjective and objective outcome postoperatively, from a short-term and a long-term perspective. A further aim was to describe GORD patients' experiences of illness and surgical treatment and if possible to find striking characteristics rela

Human glandular kallikrein 2 (hK2) in prostate cancer: Clinical and Methodological studies

Human glandular kallikrein 2 (hK2) is a predominantly prostate produced protein with many similarities to prostate-specific antigen (PSA). Just like for PSA elevated levels of hK2 can be found in men with protate cancer. We created an assay where hK2 in serum could reliably and with negligible cross-reactivity with PSA, be measured down to 0.030 ng/mL. The assay measured free hK2 and hK2 complexe

Familial and Hereditary Prostate Cancer

This thesis is based on research concerning epidemiological, clinical, and psychological aspects of familial and hereditary prostate cancer. Epidemiology: Male first-degree relatives of prostate cancer patients had a three-fold increased prostate cancer risk. The risk was higher for relatives of younger patients than for relatives of older patients, most likely due to the effect of the higher pre

Regulation and functions of basic helix-loop-helix transcription factors in neuroblastoma cells

Neuroblastoma is a childhood tumor derived from primordial neural crest cells. The tumor cells exhibit a phenotype similar to that of developing neuroblasts, which indicates that the tumor arises due to perturbed differentiation of the sympathetic nervous system. It is well established that transcription factors control the steps leading to neuronal differentiation, and a number of basic helix-loo

Ultrasound in the management of women with post-menopausal bleeding

The aim of this thesis was to investigate how ultrasound can be used in the diagnostic work-up of women with post-menopausal bleeding (PMB) to optimise and individualise their management. The thesis is based on six studies comprising post-menopausal women with (Study I-VI) and without (Study VI) abnormal bleeding. The clinical value of conventional ultrasound, with or without saline infusion (hyd

Nucleic Acids as Drug Targets -Interactions of Platinum Complexes, Polyamines, and siRNA with DNA and RNA Models

Drugs targeting nucleic acids were studied in DNA and RNA model systems. The effects were investigated with respect to structural and thermodynamic influence, kinetics, and biological function. The drugs employed in this thesis were anticancer active platinum(II) complexes, polyamine derivatives, and siRNA. Structural changes were determined by use of chemical probing and circular dichroism (CD),

Regulation of force and shortening velocity in smooth muscle

Smooth muscle is characterised by high tension economy, low shortening velocity and regulation mainly by myosin light chain (MLC) phosphorylation. The aim of this study was to investigate regulation of force and maximal shortening velocity (Vmax) in smooth muscle. In intact muscle, activated with depolarisation, inhibition of force and rise in intracellular [Ca2+] ([Ca2+]i) by 2,3-butanedione mono

Ten Years Of Sustainable Construction Aspects From A North And A South Perspective – A Review From Sustainable Building Conferences 1998-2007.

This paper is about, from a North and South different perspective, how the international focus of sustainable construction issues has changed over the past ten years. It is a review from four different international and regional sustainable building conferences between 1998 and 2007. The paper is mostly based of the first author's notes from the conferences, especially from the plenary sessions an

Striking the balance between formality and informality in safety-critical communication: Train traffic control calls

Talk in safety-critical activities displays features that distinguish it from both ordinary conversations as well as from other institutional talk, but it also shares some features with these. Formality and informality are both interactionally accomplished phenomena, although shaped through different sources. Safety rules and pre-printed forms constitute two sources of formalization, dictating how

Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology

Results from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. The focus is on the emergence of the pressure gradients betwe

Effect of IL-1beta secretion on lymphoid tissue and on antitumor immune responses

Interleukin (IL)-1beta is one of the most pleiotropic and potent cytokines, produced predominantly by activated monocytes and macrophages. IL-1 plays an important role in normal immunoregulatory processes but also in pathophysiological inflammatory responses. In the present study, we developed a model for active IL-1beta secretion. A retroviral vector containing a cDNA construct encoding the matur

Ready to stop: Socioeconomic status and the fertility transition in Stockholm, 1878-1926

The western fertility decline is arguably the most significant demographic change to have occurred in the past 200 years, yet its causes and processes are still shrouded in ambiguity due to a lack of individual-level longitudinal data. A growing body of research has helped improve our understanding of the decline's causes by examining the development of socioeconomic differences in fertility using
