Endocrine markers of ovarian function: Clinical and biological aspects with focus on Anti Müllerian hormone

Popular Abstract in English During recent decades, significant changes in fertility pattern are seen in the Western World. Declining birth rates and smaller family sizes affect the population size, but also cause unwanted effects for the desired number of children to be achieved by the individual couple. Also involuntary childlessness is a consequence of postponing childbearing to an age where theDeclining birthrates and infertility are now a common problem in the Western World. Due to the tendency to postpone childbearing an increasing age of women who consider motherhood is generally seen. A factor closely related to female fertility is the ovarian reserve, a term used to designate both quantitative as well as qualitative aspects of the remaining gametes in the female gonads. Despite a n

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

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

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/

Statusbedömning av befintliga byggnader – Med fokus på Energi, Extern miljöpåverkan och Utemiljö

Om inte statusen på Sveriges byggnadsbestånd förbättras kommer miljömålet ”God bebyggd miljö” inte kunna uppfyllas. Då miljömålet beaktar många aspekter måste ett holistiskt synsätt gälla vid genomförandet av åtgärder i byggnadsbeståndet. För att kunna göra detta måste en dialog föras kring viktiga aspekter på byggnadens samtliga områden mellan inblandade parter. Om en parameter ändras riskerar deCurrently, Sweden faces a major environmental challenge. If the status of its building stock doesn’t improve, the environmental goal “En god bebyggd miljö” will not be reached. Since this goal considers a wide range of aspects it’s essential that the same holistic approach is considered when implementing measures on the building stock. For this to be possible, an extensive dialogue needs to be hel

Reaktionsstudie vid Perstorp AB:s befintliga TMP process

TMP, kort för Trimetylolpropan, är en kemisk komponent som används som byggsten för alkydproduktion inom färgindustri samt som komponent i syntetiska smörjmedel. Perstorp har under drygt 50 år producerat TMP för vidare försäljning till andra kemiska industrier. Under denna period har produktionskapaciteten ökat många gånger om. Denna produktivitetsökning har kommit som följd av ett ”trial and erroThe production of TMP (Trimethylolpropane) is important for many applications, and is used as alkyds in paint and lubricants among others. The reactions producing TMP consist of two major reaction chains, Aldol condensation and Cannizzaro reaction. To get a deeper understanding and improve the running conditions the kinetic expressions for the reactions were examined. The aim of this paper was to

Energy poverty in the Dublin region : modelling geographies of risk

Energifattigdom definieras som ett tillstånd där ett hushåll inte kan tillgå tillräckligt med energi för att underhålla en rimlig levnadsstandard. Problemet uppstår i en kombination av låg inkomst, energikrävande bostäder och höga energikostnader. Mellan 50 och 125 miljoner invånare i Europa uppskattas vara drabbade. Utanförskap, hälsoproblem och i värsta fall att människor dör i förtid är exempelEnergy poverty (EP) is, in the scholarly literature, defined as a household’s inability to obtain a socially and materially acceptable level of energy services in the home. This is a widespread issue affecting an estimated 50 to 125 million people in Europe. Measures to tackle EP have yielded successes using proactive area-based schemes that target groups of households in the same geographic are
