The parasites Leshmania mexicana and Trypanosoma cruzi cause serious health problems, and few efficient treatments are available. Recently, the two benzochromenes pulchrol (1) and pulchral (2) were reported from the roots of Bourreria pulchra, and especially 1 but also 2 was found to be active towards the parasites. In this paper, we present a total synthesis of 1 and 2 to facilitate their biologi

Human papillomavirus (HPV) infection is a necessary factor in the cervical cancer development. Also after treatment for cervical dysplasia, HPV can be present and promote the recurrence of cervical disease. In the present study, the aim was to perform a long-term follow-up on the ability of HPV testing with genotyping, as compared with cytology, to predict recurrence of high-grade cervical intraep

Gas turbines are widely used for aircraft propulsion, land-base power generation, and other industrial applications like trains, marines, automobiles, etc. To satisfy the fast development of advanced gas turbines, the operating temperature must be increased to improve the thermal efficiency and output work of the gas turbine engine. However, the heat transferred to the turbine blade is substantial

The article examines the underlying conceptions of the practices of creativity embedded in the global copyright construction, and argues that there is a prevailing idealized image expressed in terms of individual and autonomous performance of “solitary geniuses”. This conception is an important part of what may be called a copyright ideology that increasingly has let the law develop into an indust

Aerococcus is a genus that comprises seven species, of which Aerococcus urinae, and Aerococcus sanguinicola are emerging human pathogens. Aerococci are gram positive cocci that are easily misidentified as streptococci or staphylococci, and thus the incidence of aerococcal infections has been underestimated. With the introduction of matrix-assisted laser desorption ionization time-of-flight mass sp

In contrast to most vertebrates, invertebrate deuterostome echinoderms, such as the sea star Asterias rubens, undergo regeneration of lost body parts. The current hypothesis suggests that differentiated cells are the main source for regenerating arm in sea stars, but there is little information regarding the origin and identity of these cells. Here, we show that several organs distant to the regen

Diagnostic for investigating and distinguishing different laser ion acceleration mechanisms has been developed and successfully tested. An ion separation wide angle spectrometer can simultaneously investigate three important aspects of the laser plasma interaction: (1) acquire angularly resolved energy spectra for two ion species, (2) obtain ion energy spectra for multiple species, separated accor

The effect of various doping profiles on the electronic transport in GaSb/InAs(Sb) nanowire tunnel diodes is investigated. Zn-doping of the GaSb segment increases both the peak current density and the current level in reverse bias. Top-gated diodes exhibit peak current modulation with a threshold voltage which can be controlled by Zn-doping the InAs(Sb) segment. By intentionally n-doping the InAs(

Streptococcus pyogenes is a major bacterial pathogen and a potent inducer of inflammation causing plasma leakage at the site of infection. A combination of label free quantitative mass spectrometry-based proteomics strategies were used to measure how the intracellular proteome homeostasis of S. pyogenes is influenced by the presence of human plasma, identifying and quantifying 842 proteins. In pla

Strategies employing different techniques to inhibit or stimulate neurogenesis have implicated a role for adult-born neurons in the therapeutic effect of antidepressant drugs, as well as a role in memory formation. Electroconvulsive seizures, an animal model of electroconvulsive therapy, robustly stimulate hippocampal neurogenesis but it is not known how this relates to either therapeutic efficacy

Hearing function lost by degeneration of inner ear spiral ganglion neurons (SGNs) in the auditory nervous system could potentially be compensated by cellular replacement using suitable donor cells. Donor cell-derived neuronal development with functional synaptic formation with auditory neurons of the cochlear nucleus (CN) in the brainstem is a prerequisite for a successful transplantation. Here a

This article analyzes factors shaping technological capabilities in USA and European countries, and shows that the differences between the two continents in this respect are much smaller than commonly assumed. The analysis demonstrates a tendency toward convergence in technological capabilities for the sample as a whole between 1998 and 2008. The results indicate that social capabilities, such as

The European Spallation Source (ESS) is an intergovernmental project building a multidisciplinary research laboratory based upon the world's most powerful neutron source to be built in Lund, Sweden. The ESS will use a linear accelerator which will deliver protons with 5 MW of power to the target at 2.5 GeV with a nominal current of 50 mA. The superconducting part of the linac consists of over 150

The present study focuses on the acquisition of subject-verb agreement in number in spoken French. We compare production and comprehension of singular and plural verb forms in French monolingual and French-Swedish bilingual children (n=58) aged from five to ten years. Overall, the results demonstrate that subject-verb agreement in number is a challenge to all French-speaking children, be it monoli

This article maps current approaches to public reporting on waiting times, patient experience and aggregate measures of quality and safety in 11 high-income countries (Australia, Canada, England, France, Germany, Netherlands, New Zealand, Norway, Sweden, Switzerland and the United States). Using a questionnaire-based survey of key national informants, we found that the data most commonly made avai

Genetic predisposition has been proposed to be a major determinant in the development of renal complications of diabetes. Osteopontin (OPN) has been suggested to be associated with renal diseases characterized by tubulointerstitial fibrosis and proteinuria. However, information on association of genetic polymorphisms in OPN with diabetic nephropathy is lacking. Thus, the present study was designed

Bladder exstrophy is a congenital malformation of the bladder and urethra. The genetic basis of this malformation is unknown however it is well known that chromosomal aberrations can lead to defects in organ development. A few bladder exstrophy patients have been described to carry chromosomal aberrations. Chromosomal rearrangements of 22q11.2 are implicated in several genomic disorders i.e. DiGeo

In situ high-energy surface X-ray diffraction was employed to determine the surface structure dynamics of a Pd(100) single crystal surface acting as a model catalyst to promote CO oxidation. The measurements were performed under semirealistic conditions, i.e., 100 mbar total gas pressure and 600 K sample temperature. The surface structure was studied in detail both in a steady gas flow and in a gr
