Neuroendocrine tumors (NETs) represent a heterogeneous group of diseases with varied natural history and prognosis depending upon the organ of origin and grade of aggressiveness. The most widely used biomarker to determine disease burden and monitor response to treatment is chromogranin A (CgA), but it is far from being the optimal predictive and prognostic biomarker in NETs. Biological understand

Cancer runs in families, suggesting a heritable component, but the contribution of environmental factors cannot be neglected. Studies on spousal risk can partly disentangle the environmental contribution but miss shared environmental factors during childhood and adolescence. Here, we examined the familial aggregation of common cancers among 80 281 Swedish-born adoptees, identified from the nationa

Large volcanic eruptions impact significantly on climate and lead to ozone depletion due to injection of particles and gases into the stratosphere where their residence times are long. In this the composition of volcanic aerosol is an important but inadequately studied factor. Samples of volcanically influenced aerosol were collected following the Kasatochi (Alaska), Sarychev (Russia) and also dur

In recent years there have been increasing evidence associating liver disease with hypercoagulability, rather than bleeding. The aim of the study was to evaluate the haemostatic potential in patients with liver disease.

Modulation photoreflectance spectroscopy and Raman spectroscopy have been applied to study the electronic- and band-structure evolution in (Ga,Mn)As epitaxial layers with increasing Mn doping in the range of low Mn content, up to 1.2%. Structural and magnetic properties of the layers were characterized with high-resolution X-ray diffractometry and SQUID magnetometery,respectively. The revealed res

Pebbles with sizes of centimeters to decimeters are needed in order to form kilometer-sized planetesimals, which in turn are needed for planet formation to proceed. The well-studied mechanism of coagulation is efficient only up to millimeter-sized dust grains. In this proceeding a numerical model of ice condensation as a complementary growth mechanism in turbulent protoplanetary discs is discussed

Single-carrier frequency division multiple access (SC-FDMA) is considered as a promising technique that is adopted in the uplink for the upcoming 3GPP long term evolution (LTE). This is because it keeps most of the advantages of OFDMA in addition to low peak to average power ratio (PAPR). Designing diversity achieving schemes for SC-FDMA is a challenging task. The code should not affect the PAPR a

The concept of storytelling as a description (or prescription) regarding jazz music is a very old and very common trope in jazz discourses. Arguably, however, this usage seems to have been taken for granted, and has not been sufficiently investigated and problematized. One of several important aspects of the concept of storytelling as applied to jazz music has to do with the music’s semantic poten

Within cognitive linguistics, the notion of domain is central. In the literature, the notion of domain has been interpreted in an all-encompassing way, which has led to conceptual confusion. The article proposes to distinguish between a more psychologically oriented description of domains based on dimensional structures, on the one hand; and meronomic relations, on the other. It is shown how Langa

It would be advantageous for the treatment of neonatal respiratory distress syndrome if effective amounts of surfactant could be delivered by nebulization.

We study localization, urbanization and Jacobs’ externality effects on plant survival in Sweden (1970–2004). We focus on two questions: (i) do agglomeration externalities change with the age of plants? and (ii) what is the role of technological relatedness among local industries? We find that agglomeration externalities affect survival chances of plants. This effect, however, differs between corpo

Wang Y, Roller J, Slotta JE, Zhang S, Luo L, Rahman M, Syk I, Menger MD, Thorlacius H. Distinct patterns of leukocyte recruitment in the pulmonary microvasculature in response to local and systemic inflammation. Am J Physiol Lung Cell Mol Physiol 304: L298-L305, 2013. First published December 28, 2012; doi:10.1152/ajplung.00246.2012.The mechanisms of leukocyte recruitment in the pulmonary microvas

PURPOSE: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation which is not fully reversible. Despite the heterogeneity of COPD, its diagnosis and staging is currently based solely on forced expiratory volume in 1 s (FEV(1)). FEV(1) does not explain the underlying pathophysiology of airflow limitation. The relationship between FEV(1), symptoms and emphysema extent is

Increasing resistance to antibiotics makes antimicrobial peptides interesting as novel therapeutics. Here, we report on studies of the peptide NLF20 (NLFRKLTHRLFRRNFGYTLR), corresponding to an epitope of the D helix of heparin cofactor II (HCII), a plasma protein mediating bacterial clearance.

Montmorillonite is a key ingredient in a number of technical applications. However, little is known regarding the microstructure and the forces between silicate platelets. The size of montmorillonite platelets from different natural sources can vary significantly. This has an influence on their swelling behavior in water as well as in salt solutions, particularly when tactoid formation occurs, tha

Purpose. In anesthetized patients, electro-acupuncture (EA) has been found to reduce sevoflurane-induced suppression of cranial and spinal motor responses to surgery without influencing the level of anesthesia. The underlying mechanisms are unclear. In the present study, blood samples were analyzed to evaluate if the increased clinical motor responses to surgery in patients subjected to EA under s

The emergence of automated image analysis algorithms has aided the enumeration, quantification, and immunohistochemical analyses of tumor cells in both whole section and tissue microarray samples. To date, the focus of such algorithms in the breast cancer setting has been on traditional markers in the common invasive ductal carcinoma subtype. Here, we aimed to optimize and validate an automated an

Retinopathy of prematurity (ROP) is a vision-threatening disease in premature infants. Serum adiponectin (APN) concentrations positively correlate with postnatal growth and gestational age, important risk factors for ROP development. Dietary ω-3 (n-3) long-chain polyunsaturated fatty acids (ω-3 LCPUFAs) suppress ROP and oxygen-induced retinopathy (OIR) in a mouse model of human ROP, but the mechan
