Pheromone-binding proteins (PBPs) are soluble transporter proteins that increase the capture and the solubilization of pheromone molecules in the lymph surrounding the olfactory receptors. A polymerase chain reaction-based method was used to identify PBP genes in Agrotis species for an evolutionary genomic study of noctuid moth PBPs. From genomic DNA we determined the structure of different PBP ge

Popular Abstract in Swedish En valutapolitisk silver- eller guldmyntfotregim innebär att den inhemska valutan är konvertibel och har en fast växelkurs gentemot silver eller guld. Därigenom etableras även ett normvärde för växelkurserna gentemot andra länder med motsvarande ädelmetallmyntfot. Det innebär emellertid inte att de utländska växelkurserna är helt fasta. Dess variation kring normvärdet, This dissertation deals with the process of stabilisation of foreign exchange rates in Sweden between 1834 and 1880, a period in which foreign trade and the financial system underwent radical changes. Neither was the exchange rate policy static - although it changed within a stable framework of a specie standard. The aim of the dissertation is to analyse the growing stability of foreign exchange r

During normal cooking of meat, a class of mutagenic/carcinogenic compounds called heterocyclic amines is formed. Heterocyclic amines are rapidly absorbed and metabolised in the human body, and for estimation of the intake of heterocyclic amines, it is useful to determinate their levels in the urine. Blue Chitin columns were used for the extraction and purification of heterocyclic amines from urine

The life cycles of sexually reproducing animals and flowering plants begin with male and female gametes and their fusion to form a zygote. Selection at this earliest stage is crucial for offspring quality and raises similar evolutionary issues, yet zoology and botany use dissimilar approaches. There are striking parallels in the role of prezygotic competition for sexual selection on males, cryptic

Lung surfactant (LS) is an extra-cellular lipid-protein system responsible for maintaining low surface tension in the lung and alveolar stability. Serum proteins cause dysfunction of this material, e.g. in adult respiratory distress syndrome (ARDS). BLES is a clinically used LS consisting of most of the lipids and associated proteins from bovine lung lavage. Aqueous phases of BLES at 30% and 70% h

Objective: To evaluate whether upregulation of liver and muscle uncoupling protein 2 (UCP-2) is an acute phenomenon in obstructive jaundice and associated with secondary metabolic effects. Methods: Male Sprague-Dawley rats were divided into four groups bile duct ligated (BDL) and sham-operated pair-fed (PF), ad libitum fed (AL), and controls BDL. PF. and AL rats were further divided into subgroups

Objective: it is not known how acupuncture is used in midwifery care in Sweden and what kind of requirements health-care providers have for midwives and acupuncture training programmes. The aims of this study were to survey indications for the use of acupuncture in midwifery care in Sweden, and to examine the criteria and requirements used for purchase of acupuncture education programmes. Design:

BACKGROUND: Knowledge about the social and economical determinants of prescription is relevant in health care systems like the Swedish one, which is based on the principle of equity, and which aims to allocate resources on the basis of need and not on criteria that are based on social constructs. We therefore investigated the association between patient and health care practice (HCP) characteristi

Polymeric anion-exchange membranes (AEMs) are critical components for alkaline membrane fuel cells (AMFCs) which offer several attractive advantages including the use of platinum-free catalysts and a wide choice of fuel. The development of AMFCs and other electrochemical energy systems is currently severely limited by the lack of AEMs with sufficient alkaline stability. Still, significant advances

We have implemented a visualization tool for the demonstration of a nonideal Carnot engine, operating at finite time.The cycle time can be varied using a slide bar and the pressure-volume, temperature-entropy, power-time, and efficiency-time diagrams change interactively and are shown on one screen.We have evaluated the visualization tool among engineering students at university level during an in

This paper aims to assess the spatial variability in the response of CO2 exchange to irradiance across the Arctic tundra during peak season using light response curve (LRC) parameters. This investigation allows us to better understand the future response of Arctic tundra under climatic change. Peak season data were collected during different years (between 1998 and 2010) using the micrometeorologi

The aim of the present paper is to discuss strategies to minimize contrast medium (CM) doses in patients at risk of CM-induced nephropathy (CIN) after computed tomographic angiography (CTA), and percutaneous catheter angiography (PCA) and vascular interventions (PVI). In general a gram-iodine (g-I)/eGFR ratio >= 1.0 appears to be a significant and independent predictor of CIN in CTA and coronary i

Aims/hypothesis An abnormal urinary albumin excretion rate (AER) is often the first clinically detectable manifestation of diabetic nephropathy. Our aim was to estimate the heritability and to detect genetic variation associated with elevated AER in patients with type 1 diabetes. Methods The discovery phase genome-wide association study (GWAS) included 1,925 patients with type 1 diabetes and with

Scintigraphy is the gold standard for objective measurement of delayed gastric tube emptying after esophagectomy. The aim of this pilot study is to validate, by reference to scintigraphy, the paracetamol absorption test for measuring gastric tube emptying in esophagectomized patients.

Gel dosimetry measures the absorbed radiation dose with high spatial resolution in 3D. However, recently published data show that the response of metacrylic-based polymer gels depends on the segmented delivery pattern, which could potentially be a considerable disadvantage for measurements of modern dynamic radiotherapy techniques. The aim of this study is to design a dynamic compartment model for

AIMS/HYPOTHESIS: The primary aim of the study was to investigate the risk of developing gestational diabetes in women who were exposed to tobacco smoke in utero. Secondary aims were to assess the risk of obesity and non-gestational diabetes. METHODS: Data were retrieved from the Medical Birth Register of Sweden for women who were born in 1982 (when smoking data were first registered) or later and

In experimental design and 3D reconstruction it is desirable to minimize the number of observations required to reach a prescribed estimation accuracy. Many approaches in the literature attempt to find the next best view from which to measure, and iterate this procedure. This paper discusses a continuous optimization method for finding a whole set of future imaging locations which minimize the rec

Sugammadex shows a dose-response relationship for reversal of neuromuscular block (NMB) during propofol anaesthesia. Sevoflurane, unlike propofol, can prolong the effect of neuromuscular blocking agents (NMBAs), increasing recovery time. This open-label, randomized, dose-finding trial explored sugammadex dose-response relationships, safety, and pharmacokinetics when administered for reversal of mo
