Från planering till resultat - om utvärderingsforskning i Sverige

Att en specifik utvärderingsforskning knappast existerade i Sverige före mitten av 1970-talet beror bl a på att socialpolitiska reformer normalt föregåtts av en planerings- och beslutsprocess som inneburit omfattande politisk kontrol och värdering, såväl före som under själva genomförandet. Förändringarna inom offentlig sektor, där det tidligare planeringstänkandet ersatts av en mål- och resultats

RIFM fragrance ingredient safety assessment, l-Borneol, CAS registry number 464-45-9.

The use of this material under current use conditions is supported by the existing information. This material was evaluated for Genotoxicity, Repeated Dose Toxicity, Developmental Toxicity, Reproductive Toxicity, Local Respiratory Toxicity, Phototoxicity, Skin Sensitization potential as well as Environmental assessment. Repeated Dose Toxicity was determined using read across analog to have the mos

HpaA is essential for Helicobacter pylori colonization in mice

Infection with the human gastric pathogen Helicobacter pylori can give rise to chronic gastritis, peptic ulcer, and gastric cancer. All H. pylori strains express the surface-localized protein HpaA, a promising candidate for a vaccine against H. pylori infection. To study the physiological importance of HpaA, a mutation of the hpaA gene was introduced into a mouse-adapted H. pylori strain. To justi

Prefractionation of cerebrospinal fluid to enhance glycoprotein concentration prior to structural determination with FT-ICR mass spectrometry

Glycoproteins in cerebrospinal fluid are found to be altered in Alzheimer patients compared to healthy control individuals. We have utilized micro-solution isoelectric focusing and affinity chromatography, prior to gel electrophoresis to enable site-specific structural determination of the N-linked glycans in apolipoprotein J with the use of FT-ICR MS. The albumin depletion method is the most suit

Proteome analysis of cerebrospinal fluid proteins in Alzheimer patients

By comparing the CSF proteome between Alzheimer disease (AD) patients and controls it may be possible to identify proteins that play a role in the disease process and thus to study the pathogenesis of AD. We used mini-gel technology in a two-dimensional electrophoresis procedure, sensitive SYPRO Ruby staining and mass spectrometry for clinical screening of disease-influenced CSF proteins in 15 AD

Peptide mapping of proteins in cerebrospinal fluid utilizing a rapid preparative two-dimensional electrophoretic procedure and matrix-assisted laser desorption/ionization mass spectrometry

A quick two-step procedure involving liquid phase isoelectric focusing in the Rotofor cell in combination with electroelution in the Mini whole cell gel eluter has been used for purification of proteins from human cerebrospinal fluid (CSF). Fractions, each highly enriched in a single protein band and virtually free of other proteins, were selected for characterization by matrix-assisted laser deso

Treatment of BRCA1/2-associated breast cancer and identification of mutation carriers among breast cancer patients

The general aim of the research presented in this thesis was to contribute to the understanding of how breast cancer patients with germline BRCA1/2 mutations should be treated medically and surgically, and furthermore, to characterize the limitations and strengths of different procedures for BRCA testing. In Paper I, the long-term prognosis was assessed in a cohort of early-onset breast cancer pat

Case-control analysis of truncating mutations in DNA damage response genes connects TEX15 and FANCD2 with hereditary breast cancer susceptibility

Several known breast cancer susceptibility genes encode proteins involved in DNA damage response (DDR) and are characterized by rare loss-of-function mutations. However, these explain less than half of the familial cases. To identify novel susceptibility factors, 39 rare truncating mutations, identified in 189 Northern Finnish hereditary breast cancer patients in parallel sequencing of 796 DDR gen

1/f and RTS noise in InGaAs nanowire MOSFETs

Low-frequency noise measurements were performed on high-performance InGaAs nanowire MOSFETs. 1/f noise measurements show number fluctuations, rather than mobility fluctuations, as the dominant noise source. The minimum equivalent input gate voltage noise reported here is 80 μm2μV2/Hz, among the lowest values for III-V FETs, and showing the feasibility of a high-quality, low trap density, high-k ga

A well-plate format isothermal multi-channel microcalorimeter for monitoring the activity of living cells and tissues

Design and properties are reported for a novel type of multi-channel isothermal microcalorimeter. It is equipped with 48 calorimetric units (channels) and is primarily intended for use as a monitor of the activity of living cells, tissues and small animals. Calorimetric vessels are positioned in a holder with the format of a 48-well microtiter plate. At most, 47 samples can be measured simultaneou

Socioeconomic Consequences of Childhood Onset Type 1 Diabetes – a case study of the impact of an early life health shock

Type 1 diabetes is a lifelong, chronic disease, that generally has a sudden onset early in life, which changes the conditions for the affected child and the child’s family. The overall purpose of this thesis was to explore the socioeconomic consequences of childhood onset type 1 diabetes and through this investigate how an early life health shock can affect adult socioeconomic status. The four inc

Shifting diet, shifting culture? : A bioarchaeological approach to island dietary development on Iron-Age Öland, Baltic Sea

ObjectivesThe diet and subsistence in Iron-Age Öland is debated as earlier studies and different archaeological sources seemingly provide conflicting interpretations. The objectives of this study are therefore to: (i) add new insights on diet and (ii) investigate the chronological variation in detail. It is common in studies of diet to investigate differences between datasets defined by archaeolog

Large colonial organisms with coordinated growth in oxygenated environments 2.1 Gyr ago

The evidence for macroscopic life during the Palaeoproterozoic era (2.5-1.6 Gyr ago) is controversial. Except for the nearly 2-Gyr-old coil-shaped fossil Grypania spiralis, which may have been eukaryotic, evidence for morphological and taxonomic biodiversification of macroorganisms only occurs towards the beginning of the Mesoproterozoic era (1.6-1.0 Gyr). Here we report the discovery of centimetr

Sufficient oxygen for animal respiration 1,400 million years ago

The Mesoproterozoic Eon [1,600-1,000 million years ago (Ma)] is emerging as a key interval in Earth history, with a unique geochemical history that might have influenced the course of biological evolution on Earth. Indeed, although this time interval is rather poorly understood, recent chromium isotope results suggest that atmospheric oxygen levels were 4% of present-day levels. Therefore, in cont

Long-term full-thickness embryonic rabbit retinal transplants

PURPOSE: To establish the light and electron microscopic morphology of long-term full-thickness embryonic rabbit retinal transplants, with special attention paid to graft- host integration.METHODS: Eighteen rabbits received a complete embryonic neuroretina 19 days after conception. The transplants were positioned under the host retina, flat against the host retinal pigment epithelium with proper p
