The Skylark Alauda arvensis is a European passerine species lacking plumage dimorphism and having a complete post-nuptial moult in adults, and a complete post-juvenile moult in young birds. Tongue spots were thought to allow age discrimination after moult. Based on data from a study population in the Netherlands, where the age of many birds was known, we show that tongue spots are not useful for a
Röststörningar och halsirritation anses ofta bero på gastroesofageal refluxsjukdom (GERD). Emellertid är såväl röstsymtomen som fynden vid svalg- och larynxundersökningar oftast ospecifika hos patienter med misstänkt reflux. Dessutom baseras refluxdiagnosen hos flertalet patienter enbart på just forekorosten av röst- och halssymtom. Därfor är sambanden mellan GERD och röststörningar fortfarande in
BACKGROUND: Colistin resistance in Acinetobacter baumannii is an emerging problem that limits antimicrobial therapy options.MATERIALS & METHODS: We isolated two pairs of colistin susceptible and colistin-resistant A. baumannii (K1007/K1006 and K408/K409) from two patients diagnosed with carbapenem-resistant A. baumannii infection. Colistin susceptible isolates were exposed to in vitro colistin
The outgrowth region of the regenerating frog sciatic nerve shows an increased permeability for various drugs, which has been utilized for pharmacological studies of axonal transport. Six days after a bilateral crush lesion, the nerves, including the spinal ganglia, were incubated in a compartmented chamber. Orthograde transport was assessed from the proximodistal distribution and the accumulation
The hyperfine-structure splitting for the 4 and 52P1/2 states of sodium was measured using step-wise laser excitation combined with rf-resonance techniques. The magnetic dipole interaction constants were found to be a(42P1/2)=30.4(5) MHz and a(52P1/2) =13.3(2) MHz. The results are compared with a theoretical calculation, taking polarization effects into account.
Stimulation of endogenous kinin receptors promotes growth of androgen-independent prostate cancer PC3 cells via activation of the mitogenic extracellular-signal-regulated kinase (ERK) pathway. In the present study, we show that kinin-mediated mitogenic signalling and prostate-cell growth involves two subtypes of bradykinin (BK) receptors, B1R and B2R. Specific stimulation of either B1R or B2R by t
To determine the spectrum of secreted proteins that are present in the extracellular space of early Xenopus embryos, a direct secretion screen was performed. Surprisingly, 24% of previously identified bona fide secretory proteins corresponded to four secreted Wnt antagonists of the same family: frzb-1, sizzled, sfrp-2 and crescent. sfrp-2 and crescent are novel components of the growing cocktail o
High-resolution palynofloral signatures through the Cretaceous-Palaeogene boundary succession show several features in common with the Permian-Triassic transition but there are also important differences. Southern Hemisphere Cretaceous-Palaeogene successions, to date studied at high resolution only in New Zealand, reveal a diverse palynoflora abruptly replaced by fungi-dominated assemblages that a
Methods for rapid and direct quantification of enzyme kinetics independent of the substrate stand in high demand for both fundamental research and bioprocess development. This study addresses the need for a generic method by developing an automated, standardizable HPLC platform monitoring reaction progress in near real-time. The method was applied to amine transaminase (ATA) catalyzed reactions in
SPECIES is an undulator-based soft X-ray beamline that replaced the old I511 beamline at the MAX II storage ring. SPECIES is aimed at high-resolution ambient-pressure X-ray photoelectron spectroscopy (APXPS), near-edge X-ray absorption fine-structure (NEXAFS), X-ray emission spectroscopy (XES) and resonant inelastic X-ray scattering (RIXS) experiments. The beamline has two branches that use a comm
Purpose: The purpose of the thesis is to examine how gender relations are expressed by women within the IT occupation. Moreover, our objective is also to enhance our understanding of the meanings of campaigns for increased equality, by more specifically aiming to comprehend the meaning or meanings of the #MeToo campaign. Methodology: The study is based on a qualitative abductive research approach
This paper examines the relevance of the world system as a structural condition to be considered in research on regimes and democratization. This is a pilot study in reformulating world systems analysis into the research topic of regimes, their creation and democratization. The methodology is statistical and covers most of the world for the time period 1980-1999. The study starts by formulating im
Blockchain technology has in recent years gained significant momentum in a wide variety of industries. However, in the context of SMEs the IS body of research is lacking, both in terms of why SMEs should consider this new technology and the factors that affect a potential adop-tion. To explore this research gap, the authors derived a conceptual framework from the exist-ing literature along with el
