Recurrent otitis media : genetic immunoglobulin markers in children and their parents

The likelihood that hereditary factors play a significant role in the development of recurrent acute otitis media (rAOM) in children has been suggested. The genetically determined immunoglobulin variants, Gm and Km, are useful tools for mapping out the genetic loci involved in antibody responses. Certain Gm and Km types, G2m(23) and Km(1), appear to be linked to genes which regulate the concentrat

Chondroadherin expression changes in skeletal development

Chondroadherin is a cartilage protein with cell binding properties. The expression of chondroadherin was studied in rat tissues and during postnatal femoral head development. For design of oligonucleotide probes and primers a 1664 bp, full length, rat chondroadherin cDNA was isolated from a rat chondrosarcoma library and sequenced. Northern blot analysis showed chondroadherin mRNA to be present in

Transforming Indonesia: Structural change in a regional perspective, 1968-2010

Since 1968, Indonesia has been among the few developing countries able to sustain per capita income growth over 5%. However, poverty and surplus labor are still main features of the economy. We ask to what extent the dual nature of growth has stimulated structural change, or just rewarded a particular sector or region. We find that the emblematic State support to agriculture has not untapped the p

Exploration of Electro-Enhanced-Chemotherapy I : Exploration of the uptake of radioactive tracer in rat Muscle tissue of 2 - 12 applied electric pulses of 600;800;1000;1200 V/cm field-strength, 100;250;500 s pulse-length, and 2,4,6,8.10.12 number.

Performance of the ATLAS track reconstruction algorithms in dense environments in LHC Run 2

With the increase in energy of the Large Hadron Collider to a centre-of-mass energy of 13 TeV for Run 2, events with dense environments, such as in the cores of high-energy jets, became a focus for new physics searches as well as measurements of the Standard Model. These environments are characterized by charged-particle separations of the order of the tracking detectors sensor granularity. Basic

Search for new phenomena in dijet events using 37 fb-1 of pp collision data collected at s =13 TeV with the ATLAS detector

Dijet events are studied in the proton-proton collision data set recorded at s=13 TeV with the ATLAS detector at the Large Hadron Collider in 2015 and 2016, corresponding to integrated luminosities of 3.5 fb-1 and 33.5 fb-1 respectively. Invariant mass and angular distributions are compared to background predictions and no significant deviation is observed. For resonance searches, a new method for

Semantic segmentation of microscopic images of H&E stained prostatic tissue using CNN

There is a need for an automatic Gleason scoring system that can be used for prostate cancer diagnosis. Today the diagnoses are determined by pathologists manually, which is both a complex and a time-consuming task. To reduce the pathologists' workload, but also to reduce variations between different pathologists, an automatic classification system would be of great use. Some previous works have a

“Google is not fun” : an investigation of how Swedish teenagers frame online searching

Purpose: The purpose of this paper is to investigate the role of Google in everyday online searching activities of Swedish teenagers in different contexts. Design/methodology/approach: The study is qualitative and material has been produced through interviews and observations in two different schools with participants aged 15-16. Goffman’s frame analysis provides the analytical lens for studying h

Detection of free oxygen and water vapor in fertilized and unfertilized eggs by diode laser spectroscopy-Exploration of diagnostics possibilities

Nonintrusive methods for characterizing food products are of increasing interest related to the greater awareness of food safety issues. Hen eggs are an important part in food consumption in most parts of the world. We have investigated an optical method utilizing tunable diode lasers for monitoring free gas in eggs. We show that oxygen signals, recorded around 760nm, increase steadily as eggs bec

Molecularly imprinted polymers synthesized via template immobilization on fumed silica nanoparticles for the enrichment of phosphopeptides

Phosphorylation is a protein post-translational modification (PTM) that plays an important role in cell signaling, cell differentiation, and metabolism. The hyper phosphorylated forms of certain proteins have been appointed as biomarkers for neurodegenerative diseases, and phosphorylation-related mutations are important for detecting cancer pathways. Due to the low abundance of phosphorylated prot

On electric resistance effects of non-homogeneous GDL deformation in a PEM fuel cell

The electric resistance is very important for the performance of a proton exchange membrane (PEM) fuel cell. However, the performance analysis is more complex as the cell operates under assembly conditions. At such conditions, the mass transfer is deteriorated but the electric conductivity is favored. In this paper, the electric resistance of a cell is evaluated by application of a recently develo

Crop management affects pollinator attractiveness and visitation in oilseed rape

Ecological intensification of agriculture implies managing ecological processes to improve performance of agricultural systems. However, impacts on relevant ecological functions such as insect pollination from other crop management factors are poorly explored. Pest insects and crop resources such as water availability can directly affect crop yields, but it is unknown if there are indirect effects

Heat treatment of low-alloyed steel up to grade Q125

This work investigates the problem of how to reduce the prime cost of Grade Q125 Group 4 casing and tubing according to API 5CT and proposes process solutions to resolve it, consisting in the enhancement of series of mechanical properties without chemical alloying of steel with expensive elements such as chromium, molybdenum, vanadium, niobium and boron. During the investigation the process parame

2D Ruddlesden-Popper Perovskites for Optoelectronics

Conventional 3D organic-inorganic halide perovskites have recently undergone unprecedented rapid development. Yet, their inherent instabilities over moisture, light, and heat remain a crucial challenge prior to the realization of commercialization. By contrast, the emerging 2D Ruddlesden-Popper-type perovskites have recently attracted increasing attention owing to their great environmental stabili

Tryptophan end-tagging for promoted lipopolysaccharide interactions and anti-inflammatory effects

The objective of the present study is the investigation of possibilities for boosting peptide antiinflammatory effects by tryptophan end-tagging, including identification of underlying mechanisms for this. In doing so, effects of tryptophan end-tagging of KYE21 (KYEITTIHNLFRKLTHRLFRR), a peptide derived from heparin co-factor II, on membrane and lipopolysaccharide (LPS) interactions were investiga
