Identification of a sex pheromone produced by sternal glands in females of the caddisfly Molanna angustata Curtis.

In the caddisfly Molanna angustata, females produce a sex pheromone in glands with openings on the fifth sternite. Gas chromatographic analyses of pheromone gland extracts with electroantennographic detection revealed four major compounds that stimulated male antennae. These compounds were identified by means of gas chromatography-mass spectrometry and enantioselective gas chromatography as heptan

A Gender-Just Peace: Exploring the Post-Dayton Peace Process

This article is rooted in the understanding that global ideas of liberal democratic peace and the gendered dynamics of peacebuilding need to be confronted. The aim is to explore the challenges of localizing liberal democratic peace by exploring efforts such as those undertaken by women’s organizations in Bosnia-Herzegovina to promote a gender-just peace. The Dayton Peace Accord was the new “social

Challenging modeling strategies for LES of non-adiabatic turbulent stratified combustion

Five different low-Mach large eddy simulations are compared to the turbulent stratified flame experiments conducted at the Technical University of Darmstadt (TUD). The simulations were contributed by TUD, the Institute for Combustion Technology (ITV) at Aachen, Lund University (LUND), the EM2C laboratory at Ecole Centrale Paris, and the University of Duisburg-Essen (UDE). Combustion is modeled by

Recognition bias and the physical attractiveness stereotype.

Previous studies have found a recognition bias for information consistent with the physical attractiveness stereotype (PAS), in which participants believe that they remember that attractive individuals have positive qualities and that unattractive individuals have negative qualities, regardless of what information actually occurred. The purpose of this research was to examine whether recognition b

Polymerase chain reaction is superior to serology for the diagnosis of acute Mycoplasma pneumoniae infection and reveals a high rate of persistent infection

Background: Diagnosis of Mycoplasma pneumoniae (MP) infection is traditionally based on serology, which may require more than two weeks for diagnostic antibodies to develop. PCR-based methods offer earlier diagnosis. During a community outbreak of MP infection, we compared seminested and real-time PCR of oropharyngeal swabs with serology for diagnosis of MP infection at different time points after

Determination of serum amyloid P component in seminal plasma and correlations with serum hormone levels in young, healthy men.

Abstract Serum amyloid P component (SAP) belongs to the pentraxin family of proteins. SAP is evolutionary conserved, and involved in amyloidosis, innate immunity, inflammation, and apoptosis. We have previously described SAP in the male reproductive tract, where it occurs in seminal fluid, on spermatozoa, and in epididymal, seminal vesicle, and prostate tissue. In the present investigation, our ai

Reconstructing range dynamics and range fragmentation of European bison for the last 8000 years

Aim Understanding what constituted species ranges prior to large-scale human influence, and how past climate and land use change have affected range dynamics, provides conservation planners with important insights into how species may respond to future environmental change. Our aim here was to reconstruct the Holocene range of European bison (Bison bonasus) by combining a time-calibrated species d

Possible role of ectomycorrhizal fungi in cycling of aluminium in podzols

Budget studies in boreal podzols indicate a considerable upward transport of aluminium (Al) from the mineral soil into the organic horizon. In this paper we studied if ectomycorthizal (EcM) fungi can be involved in this upward transport via their extramatrical hyphae. We tested the use of gallium (Ga) as proxy for Al. Transport of Al through EcM hyphae was studied in vitro in a two-compartment Pet

Cursed complexity. Computational properties of subcortical neuronal microcircuitry in sensorimotor control

One of the big obstacles for understanding the nervous system is its inherent complexity. It poses problems when interpreting both experimental and theoretical studies since we are currently forced to consider only reduced variants of the actual circuitry of the brain. Since there exist problems that do not appear until a system is sufficiently complex, there are no guarantees that the results ste

Using pictures and artefacts in a PAR process to disclose new wor(l)ds of entrepreneurship

Drawing on Freire, this article elaborates on how pictures and artefacts benefit processes of 'prise de conscience' and 'conscientization' among those with powerful voices. Wor(l)d-making was unfolded in the Swedish think-and-do tank, 'the Smithy', emphasizing the intrinsically political nature of promoting 'societal entrepreneurship' (SE). New words for SE were formulated and a more inclusive wor

Analysis of Alpha-Synuclein in Malignant Melanoma - Development of a SRM Quantification Assay.

Globally, malignant melanoma shows a steady increase in the incidence among cancer diseases. Malignant melanoma represents a cancer type where currently no biomarker or diagnostics is available to identify disease stage, progression of disease or personalized medicine treatment. The aim of this study was to assess the tissue expression of alpha-synuclein, a protein implicated in several disease pr

Characterization of Released Polypeptides During an Interferon-γ-Dependent Antibacterial Response in Airway Epithelial Cells.

When pathogenic bacteria breach the epithelial lining at mucosal surfaces, rapidly available innate immune mechanisms are critical to halt the infection. In the present study, we characterized the production of antibacterial polypeptides released by epithelial cells. IFN-γ, but neither TNF nor IL-1β alone, induced release of antibacterial activity to a cell culture medium, causing a lytic appearan

Quantum interference in off-resonant transport through single molecules

We provide a simple set of rules for predicting interference effects in off-resonant transport through single molecule junctions. These effects fall into two classes, showing, respectively, an odd or an even number of nodes in the linear conductance within a given molecular charge state, and we demonstrate how to decide the interference class directly from the contacting geometry. For neutral alte

CD44 isoforms are heterogeneously expressed in breast cancer and correlate with tumor subtypes and cancer stem cell markers.

BACKGROUND: The CD44 cell adhesion molecule is aberrantly expressed in many breast tumors and has been implicated in the metastatic process as well as in the putative cancer stem cell (CSC) compartment. We aimed to investigate potential associations between alternatively spliced isoforms of CD44 and CSCs as well as to various breast cancer biomarkers and molecular subtypes. METHODS: We used q-RT

Investigation of atmospheric insect wing-beat frequencies and iridescence features using a multispectral kHz remote detection system

Quantitative investigation of insect activity in their natural habitat is a challenging task for entomologists. It is difficult to address questions such as flight direction, predation strength, and overall activities using the current techniques such as traps and sweep nets. A multispectral kHz remote detection system using sunlight as an illumination source is presented. We explore the possibili

Developing strategic supplier networks: An institutional perspective

This study examines the exposure of the members of supplier networks to two layers of social influences. First, as the network connects an actor to a foreign constellation, the actor faces influences of a global character. Second, each individual actor experiences different forces emanating from its indigenous institutional environment. The exposure to two institutional practices presents a conund
