Cancer of unknown primary (CUP): does cause of death and family history implicate hidden phenotypically changed primaries?

Cancer of unknown primary (CUP) is diagnosed at the metastatic stage. We aimed to identify hidden primary cancers in CUP patients by comparison with cancers in family members. We take use of the fact that the cause of death in CUP patients is often coded as the cancer in the organ of fatal metastasis. Forty-one thousand five hundred and twenty-three CUP patients were identified in the Swedish Fami

Laminar burning velocity of gasolines with addition of ethanol

The adiabatic laminar burning velocities of a commercial gasoline and of a model fuel (n-heptane, iso-octane, and toluene mixture) of close research octane number have been measured at 358 K. Non-stretched flames were stabilized on a perforated plate burner at 1 atm. The heat flux method was used to determine burning velocities under conditions for which the net heat loss of the flame is zero. Ver

Trötta mammors försvarare : familjevärderingar i Kerstin Thorvalls bilderböcker från 1970-talet

Kerstin Thorvall (1925–2010) is a Swedish author of books for children and young adults, as well as books for adults. In 1965, she wrote the article “Do all authors of children's books live in Tomtebolandet?” (“Bor alla barnboksförfattare i Tomtebolandet”, Expressen 1965) in which she claims that gender roles in Swedish children's literature, are depicted in an old and stereotypical fashion. She a

HLA Class I and Genetic Susceptibility to Type 1 Diabetes Results From the Type 1 Diabetes Genetics Consortium

OBJECTIVE-We report here genotyping data and type 1 diabetes association analyses for HLA class I loci (A, B, and C) on 1,753 multiplex pedigrees from the Type 1 Diabetes Genetics Consortium (T1DGC), a large international collaborative study. RESEARCH DESIGN AND METHODS-Complete eight-locus HLA genotyping data were generated. Expected patient class I (HLA-A, -B, and -C) allele frequencies were cal

Monocytes and macrophages, with a focus of Crohn's disease

Monocytes and macrophages are part of the body’s first line of defense, eliminating pathogens by phagocytosis or by releasing a broad array of inflammatory mediators, such as cytokines, chemokines and proteases. In humans, three subsets of monocytes are described with seemingly different functions. The classical (CD14++CD16-) monocytes, the intermediate (CD14++CD16+) monocytes and the non-classica

Measurement of the b-hadron production cross section using decays to D*(+)mu X- final states in pp collisions at root s=7 TeV with the ATLAS detector

The b-hadron production cross section is measured with the ATLAS detector in pp collisions at root s = 7 TeV, using 3.3 pb(-1) of integrated luminosity, collected during the 2010 LHC run. The b-hadrons are selected by partially reconstructing D*(+)mu X- final states. Differential cross sections are measured as functions of the transverse momentum and pseudorapidity. The measured production cross s

Effect of Heat Treatment on the Circular Dichroism Spectra of Bovine β Lactoglobulin A, B and C.

Dilute solutions of -lactoglobulin (-Lg) A, B, and C were heated in phosphate buffer at temperatures between 40 and 94 C for 10 min, cooled, and analyzed using near-UV and far-UV circular dichroism (CD). The decrease in near-UV CD intensity at 293 nm (293) could be analyzed in terms of a two-state model, and the stability was -Lg C > -Lg A > -Lg B on the basis of the midpoint temperatures for samp

The N-terminal N5 subdomain of the alpha 3(VI) chain is important for collagen VI microfibril formation

Collagen VI assembly is unique within the collagen superfamily in that the alpha 1(VI), alpha 2(VI), and alpha 3(VI) chains associate intracellularly to form triple helical monomers, and then dimers and tetramers, which are secreted from the cell. Secreted tetramers associate end-to-end to form the distinctive extracellular microfibrils that are found in virtually all connective tissues. Although

Reduced grazing rates in Daphnia pulex caused by contaminants: Implications for trophic cascades

Ecotoxicological endpoints based on behavioral traits (e.g., predator avoidance, feeding, and locomotion) may be more sensitive and give more insights into patterns of sublethal toxicity than survivorship tests. In this study, the density-dependent grazing rate of Daphnia pulex pre-exposed to p,p'-dichlorodiphenyldichloroethylene (DDE) (insecticide metabolite) and glyphosate (herbicide), via water

Applications of two-photon absorption for detection of CO in combustion gases

Laser-induced fluorescence has been used for detection of CO in different environments. The fluorescence light was obtained by using a two-photon transition between theX1?- and theB1?- electronical states around 230 nm. Cell measurements indicate a detection limit lower than 0.1 ppm. Measurements in a CH4/air flame and in a low pressure dc discharge were realized with a diode-array detector, which

Alteration of intestinal microflora is associated with reduction in abdominal bloating and pain in patients with irritable bowel syndrome

OBJECTIVE: The influence of the gastrointestinal (GI) microflora in patients with irritable bowel syndrome (IBS) has not been clearly elucidated. This study was undertaken to see if patients with IBS have an imbalance in their normal colonic flora, as some bacterial taxa are more prone to gas production than others. We also wanted to study whether the flora could be altered by exogenous supplement

Predicting the Displacement of Yogurt by Water in a Pipe Using CFD

A numerical scheme based on the volume of fluid (VOF) method for predicting the displacement of one liquid by another has been verified versus electrical resistance tomography (ERT) and ultrasonic velocity profile (UVP) measurements for the displacement of yoghurt by water. The scheme using the VOF method predicts the skewed phase distribution as measured using ERT and the global structure of the

International Biofuel Trade - A Study of the Swedish Import

Following the development of large-scale use of biomass energy in the EU, international biofuel trade is a plausible scenario and something that is already taking place in Northern Europe. This paper focuses on Swedish biofuel imports, both direct and indirect imports, the latter which derive from the fact that part of the imported pulpwood and timber end up as fuel. The objective is to describe t

Transport properties and aggregation phenomena of polyoxyethylene sorbitane monooleate (polysorbate 80) in pig gastrointestinal mucin and mucus

The aqueous environment in the gastrointestinal tract frequently requires solubilization of hydrophobic drug molecules in appropriate drug delivery vehicles. An effective uptake/absorption and systemic exposure of a drug molecule entails many processes, one being transport properties of the vehicles through the mucus layer. The mucus layer is a complex mixture of biological molecules. Among them,

Precise in situ thickness analysis of epitaxial graphene layers on SiC(0001) using low-energy electron diffraction and angle resolved ultraviolet photoelectron spectroscopy

We demonstrate an easy and practical method for the thickness analysis of epitaxial graphene on SiC(0001) that can be applied continuously during the preparation procedure. Fingerprints in the spot intensity spectra in low energy electron diffraction (LEED) allow for the exact determination of the number of layers for the first three graphene layers. The LEED data have been correlated with the ele

Identification, synthesis and activity of sex pheromone gland components of the autumn gum moth (Lepidoptera : Geometridae), a defoliator of Eucalyptus

The autumn gum moth, Mnesampela privata (Guenee) (Lepidoptera: Geometridae), is native to Australia and can be a pest of plantation eucalypts. Field-collected and laboratory-reared female autumn gum moths were dissected to remove glands likely to contain components of the sex pheromone. Using gas chromatography (GC) and combined gas chromatography-mass spectrometry (GC-MS), three compounds were id
