Power spectrum analysis of heart rate variability (HRV) may provide insight into the mental state of the animal held in restricted specific experimental conditions. Determining inter-beat-interval (IBI) variations is one way to measure changes in autonomic nervous system (ANS) activity in horses. An imbalance between the sympathetic and parasympathetic nervous system can indicate pain or stress, f
Background: Congenital cardiovascular diseases are the most common form of birth defects in humans. A substantial portion of these defects has been associated with inappropriate induction, migration, differentiation and patterning of pluripotent cardiac neural crest stem cells. While TGF-beta superfamily signaling has been strongly implicated in neural crest cell development, the detailed molecula
OBJECTIVE: To examine the associations between the consumption of fruit and vegetables and other markers of cancer risk. DESIGN: A cross-sectional survey within the population-based prospective Malmo Diet and Cancer (MDC) Study. Information on food habits was collected through the modified diet history method designed and validated for the MDC Study. Data on smoking and alcohol habits, leisure tim
Noroviruses (formerly Norwalk-like viruses) are a major cause of acute gastroenteritis worldwide and are associated with a significant number of nosocomial and food-borne outbreaks. In this study we show that the human secretor FUT2 gene, which codes for an alpha(1,2)-fucosyltransferase synthesizing the H-type 1 antigen in saliva and mucosa, is associated with susceptibility to norovirus infection
BACKGROUND: Severe alpha 1-antitrypsin (AAT) deficiency (PiZZ) is associated with an increased risk of lung emphysema, especially in smokers. The aim of this study was to identify risk factors other than smoking for declining lung function. METHODS: Lung function was studied in 225 self-reported never-smoking PiZZ individuals included in the Swedish AAT deficiency register. RESULTS: Lung function
The type of chemical reaction between hapten and carrier protein in the formation of a complete antigen in vivo giving rise to an allergic contact dermatitis (ACD, type IV allergy) is essentially unknown. About 4,000 low-molecular organic compounds are known to have allergenic properties. ,-Unsaturated carbonyl structures are frequently present among these compounds. Haptens giving rise to antibod
Hemopoietic stem cells (HSCs) are maintained at relative quiescence by the balance between the positive and negative regulatory factors that stimulate or inhibit their proliferation. Blocking the action of negative regulatory factors may provide a new approach for inducing HSCs into proliferation. A variety of studies have suggested that TGF-beta negatively regulates cell cycle progression of HSCs
Volatiles from Ips duplicatus male hindgut extracts and aeration samples of spruce logs colonized by the virgin males were analyzed by coupled gas chromatography-mass spectrometry (GC-MS), coupled gas chromatography-electroantennographic detection (GC-EAD), and field trapping bioassays in Inner Mongolia, China. GC-MS analyses showed that males from nuptial chambers (for reproduction) produced hind
Objective To determine whether subjective evaluation of the morphology of the vessel tree of ovarian tumors, as depicted by three-dimensional (3D) power Doppler ultrasound, can discriminate between benign and malignant ovarian tumors, and whether it improves characterization compared with using gray-scale ultrasound imaging alone. Methods A consecutive series of 104 women scheduled for surgical r
Popular Abstract in Swedish Jätteplaneterna, Jupiter, Saturnus, Uranus och Neptunus, är de största planeterna i solsystemet. De ligger långt från solen och har alla betydande gasatmosfärer, upp emot hundra gånger mer massiva än hela jorden. Tack vare de tjocka gashöljena, med en sammansättning som liknar solens, kan man förstå att jätteplaneterna bildades i en gasskiva. Denna skiva kallas för solGiant planets form embedded in a protoplanetary disc around a young star. Close to the midplane a large fraction of the available mass in solids is found in particles of cm to dm in size, which drift towards the star due to friction with the surrounding gas. In paper I, II, III we describe a novel theory that explains how embryos, planetesimals larger than ~1000 km, grow efficiently by sweeping up
One of Scanias earliest castles, Grevlunda, has been reinvestigated. The first excavation in 1913 gave an interesting result but the time was not ripe for understanding what really was found. In 2002 archaeologists in corporation with historians, and culture geographers found out that the Grevlunda was a motte of a rare construction. The pottery material gave a dating to the late 12:th century. Th
This paper investigates the impact of the completion of the liberalized European Internal Electricity Market on Integrated Resource Planning (IRP) and Demand-Side Management (DSM). The results presented are part of the outcomes of a study analyzing the possibilities of IRP and DSM in this new industry environment. The study, finished in May 2000, is based on empirical surveys of both the present a
Within a UN Joint Programme titled “Enhancing the Capacity of Turkey to Adapt to Climate Change” a systems approach workshop was carried out in Adana, Turkey with broad stakeholder participation. The participants applied systems thinking approach, causal loop diagramming methodology and systems analysis to examine the potential impacts of projected climatic changes on natural ecosystems and socio-
The spoilage flora of refrigerated raw and pasteurized milk was classified and identified by numerical phenotypic analysis. Isolations of bacteria were made at a defined spoilage stage, when the total aerobic count was 106-107 cfu per ml. The secondary flora of ripened Swedish and Norwegian cheeses was investigated by numerical analysis. Aeromonas and Enterobacteriaceae spp. isolated from the spoi
Popular Abstract in Swedish En bred, distinkt materialpresentation är knuten till enskilda variabler av psykologiskt märke. Dessa innebär ett sök efter den autentiske Garborg, värderat som såväl symptombärare som symptomlösare. Introduktionen till Garborgs levnadshistoria avser att vara en invitation, speciellt till dem som inte är bekanta med honom som person och författare. Utifrån en period kriA broad, distinctive material presentation is done, which is linked to some variables of psychological value, stating a research for the authenticity of Garborg in viewing him as well a symptom bearer as a symptom solver. An introduction to Garborg is meant to be an invitation, especially to those who are not so well acquainted with him as a person and a writer. Out from a period of about 110 year
We present an estimate for the convergence rate of the Dirichlet-Neumann iteration for the discretized unsteady transmission problem. Specifically, we consider the coupling of two heat equations on two identical squared domains. The Laplacian is discretized by second order central finite differences and the implicit Euler method is used for the time discretization. For the semidiscrete case, Hensh
Total offers have become increasingly common in the aircraft industry during recent years. The total offers bring on challenges as well as possibilities for the providers of engine maintenance. The possibilities, increased profitability and efficiency, are depending on how the organisation copes with the challenges. An important challenge is the transfer of risk that occurs in a fixed price situat
The phosphatidylinositol 3-kinase/AKT pathway is an integral component of signaling involved in the development of many cancers, including myeloid leukemias such as chronic myeloid leukemia and acute myeloid leukemia (AML). Increased AKT1 activity is frequently seen in AML patients, providing leukemic cells with growth and survival promoting signals. An important aspect of AKT1 function is its inv
Background/Objective: Previous studies have found that ethnicity influences glycemic control. We hypothesized that differences between Nordic and non-Nordic patients are less pronounced for children with type 1 diabetes in high incidence countries in Northern Europe. Research design and methods: We investigated patients aged 0-15 yr in national pediatric registers in Denmark (D), Iceland (I), Norw
