Alpha1-Antitrypsin: New insights into the biological role in vitro and in vivo

Alpha1-Antitrypsin (AAT), an acute-phase glycoprotein produced predominantly in the liver by hepatocytes, but also by macrophages, pulmonary alveolar cells and intestinal epithelial cells, is a member of the SERPIN superfamily (SERine Protease INhibitors), and is one of the major inhibitors of neutrophil elastase in human plasma. Although AAT plays a critical role in regulating inflammation by inh

Thyroid hormones and breast cancer-prospective studies on incidence, mortality and prognostic factors

Popular Abstract in Swedish Sköldkörtelhormoner och bröstcancer Insjuknandet i sköldkörtelsjukdomar är liksom bröstcancer vanligast hos kvinnor efter klimakteriet och ett eventuellt samband har diskuterats i över ett sekel. Experimentella studier har visat att sköldkörtelhormoner påverkar både utveckling av normala bröstceller och tillväxt av bröstcancerceller. Det finns också belägg för att sköThyroid hormones and breast cancer-prospective studies on incidence, mortality and prognostic factors The aim of this thesis was to investigate in a prospective design, thyroid hormones in relation to breast cancer risk, mortality and prognostic factors. The association between total triiodothyronine (T3) levels and breast cancer risk was studied in 2185 women with146 incident breast cancer case

Thickness dependent variations in surface phosphor thermometry during transient combustion in an HCCI engine

Phosphor thermometry is a semi-invasive measurement technique which is commonly used for temperature determination in combustion applications. Surface temperature measurements using thermographic phosphors rely on the assumption that the phosphor layer is thin enough in order to adopt the surface temperature non-intrusively. This work compares the temperature information, recorded from two opposin

Dry and wet heat transfer through clothing dependent on the clothing properties under cold conditions

The purpose of this study was to investigate the effect of moisture on the heat transfer through clothing in relation to the water vapour resistance, type of underwear, location of the moisture and climate. This forms part of the work performed for work package 2 of the European Union THERMPROTECT project. Thermal manikin results of dry and wet heat loss are presented from different laboratories f

Overall asthma control: The relationship between current control and future risk

Background: Asthma guidelines emphasize both maintaining current control and reducing future risk, but the relationship between these 2 targets is not well understood. Objective: This retrospective analysis of 5 budesonide/formoterol maintenance and reliever therapy (Symbicort SMART Turbuhaler*) studies assessed the relationship between asthma control questionnaire (ACQ-5) and Global Initiative fo

Specialiserat flinthantverk på Hisingen

In this paper, the flint depositions at Tuve 46 are analysed. Here around 30 depositions containing several thousands of waste flakes were recovered together with flint tools such as large bifaces, thick-butted axes, spoon-shaped scrapers, bifacial points. It is suggested that specialized flint knappers from flint-rich areas in southern Scandinavia came to the site during the early Late Neolithic

A diagrammatic description of the equations of motion, current and noise within the second-order von Neumann approach

We investigate the second-order von Neumann approach from a diagrammatic point of view and demonstrate its equivalence with the resonant tunneling approximation. The investigation of higher order diagrams shows that the method correctly reproduces the equation of motion for the single-particle reduced density matrix of an arbitrary non-interacting many-body system. This explains why the method rep

Low-Grade Chronic Inflammation in the Relationship between Insulin Sensitivity and Cardiovascular Disease (RISC) Population Associations with insulin resistance and cardiometabolic risk profile

OBJECTIVE - Low-grade chronic inflammation has been hypothesized to underlie the constellation of cardiometabolic risk factors, possibly by inducing insulin resistance. In the present study, we investigated associations between inflammation markers, insulin sensitivity (expressed as the ratio of the M value to the mean plasma insulin concentrations measured during the Final 40 min of the clamp [M/

Hospital admission rates among men and women with symptoms of chronic bronchitis and airflow limitation corresponding to the GOLD stages of chronic obstructive pulmonary disease - A population-based study

Chronic obstructive pulmonary disease is a major cause of increased morbidity and mortality. The aim of this study was to investigate hospital admission rates among individuals with symptoms of chronic bronchitis and among those with airflow limitation corresponding to GOLD stages 1-4. Method: Between 1974 and 1992, 22 044 middle-aged individuals participated in a health screening, which included

Effect of femoral head size on polyethylene wear and synovitis after total hip arthroplasty - A sonographic and radiographic study of 39 patients

Background and purpose The role of synovitis and high fluid pressure in the loosening process after total hip arthroplasty has gained increasing attention. We investigated the correlation between head size, polyethylene wear, and capsular distention. Patients and methods We analyzed 39 unrevised, radiographically stable hips that had been operated with 28 or 32 mm femoral heads 10 years earlier be

47-channel burst-mode recording hydrophone system enabling measurements of the dynamic echolocation behavior of free-swimming dolphins.

Detailed echolocation behavior studies on free-swimming dolphins require a measurement system that incorporates multiple hydrophones (often >16). However, the high data flow rate of previous systems has limited their usefulness since only minute long recordings have been manageable. To address this problem, this report describes a 47-channel burst-mode recording hydrophone system that enables high

Modeling of cotunneling in quantum dot systems

Transport through nanosystems is treated within the second-order von Neumann approach. This approach bridges the gap between rate equations which neglect level broadening and cotunneling, and the transmission formalism, which is essentially based on the single-particle picture thereby treating many-particle interactions oil an approximate level. Here we provide an alternative presentation of the m

Further examination of prolate-shape dominance in nuclear deformation

The observed almost complete dominance of prolate over oblate deformations in the ground states of deformed even-even nuclei is related to the splitting of high center dot "surface" orbits in the Nilsson diagram: on the oblate side the occurrence of numerous strongly avoided crossings which reduce the fanning out of the low Lambda orbits, while on the prolate side the same interactions increase th

Ovarian cancer prediction in adnexal masses using ultrasound-based logistic regression models: a temporal and external validation study by the IOTA group

Objectives The aims of the study were to temporally and externally validate the diagnostic performance of two logistic regression models containing clinical and ultrasound variables in order to estimate the risk of malignancy in adnexal masses, and to compare the results with the subjective interpretation of ultrasound findings carried out by an experienced ultrasound examiner ('subjective assessm

Independent evolution of neurotoxin and flagellar genetic loci in proteolytic Clostridium botulinum

Background: Proteolytic Clostridium botulinum is the causative agent of botulism, a severe neuroparalytic illness. Given the severity of botulism, surprisingly little is known of the population structure, biology, phylogeny or evolution of C. botulinum. The recent determination of the genome sequence of C. botulinum has allowed comparative genomic indexing using a DNA microarray. Results: Whole ge

Generalizing the Gibbard-Satterthwaite theorem: partial preferences, the degree of manipulation, and multi-valuedness

The Gibbard–Satterthwaite (GS) theorem is generalized in three ways: First, it is proved that the theorem is still valid when individual preferences belong to a convenient class of partial preferences; second, it is shown that every non-dictatorial surjective social choice function (SCF) is not only manipulable, but it can be manipulated in such a way that some individual obtains either his best o
