Greedy de novo motif discovery to construct motif repositories for bacterial proteomes

BACKGROUND: Bacterial surfaces are complex systems, constructed from membranes, peptidoglycan and, importantly, proteins. The proteins play crucial roles as critical regulators of how the bacterium interacts with and survive in its environment. A full catalog of the motifs in protein families and their relative conservation grade is a prerequisite to target the protein-protein interaction that bac

Generation of large-area tunable uniform electric fields in microfluidic arrays for rapid DNA separation

Control of electric fields over large areas is crucial for the accurate delivery and manipulation of biologically important molecules in microfluidic systems. In this paper we present a novel method for generating tunable uniform electric fields over large microfluidic arrays in two dimensions, and its application to a microfabricated device that separates genomic DNA. The device fractionates larg

Limited Consequences of a Transition From Activity-Based Financing to Budgeting : Four Reasons Why According to Swedish Hospital Managers

Activity-based financing (ABF) and global budgeting are two common reimbursement models in hospital care that embody different incentives for cost containment and quality. The purpose of this study was to explore and describe perceptions from the provider perspective about how and why replacing variable ABF by global budgets affects daily operations and provided services. The study setting is a la

Hemodynamic assessment in patients with congenital heart disease using magnetic resonance imaging

Cirka 1000 barn föds med hjärtfel i Sverige varje år och idag överlever de flesta och uppnår vuxen ålder. Det finns uppskattningsvis 2.3 miljoner vuxna med medfött hjärtfel i Europa idag, en siffra som förväntas öka. Samtidigt har prevalensen av patienter med komplexa medfödda hjärtfel också ökat de senaste 10 åren. Det finns således ett behov av att öka kunskapen om patofysiologin vid dessa sjukdAround 1000 children are born with a heart disease in Sweden every year and today most of these children survive and reach adult age. There are around 2.3 million grownups with congenital heart disease in Europe today, a number that is expected to continue to increase. Further, the prevalence of patients with complex malformations has been growing significantly the last 10 years. There is thus a n

Analytical validation of a standardized scoring protocol for Ki67 immunohistochemistry on breast cancer excision whole sections: an international multicenter collaboration

Aims: The nuclear proliferation marker Ki67 assayed by immunohistochemistry has multiple potential uses in breast cancer, but an unacceptable level of interlaboratory variability has hampered its clinical utility. The International Ki67 in Breast Cancer Working Group has undertaken a systematic programme to determine whether Ki67 measurement can be analytically validated and standardised among lab

Qualifying and Quantifying Thermal Comfort in Highly Glazed Spaces

This paper aims to answer a simple and elemental question: how do we qualify and quantify thermal comfort in highly glazed spaces with diverse occupants’ use and expectation? And, how can designers achieve enhanced occupant experience with passive measures, minimizing the use of HVAC systems in such spaces? In this study variables, such as air and radiant temperatures, air velocity, relative humid

Models of our Galaxy - II

Stars near the Sun oscillate both horizontally and vertically. In a previous paper by Binney it was assumed that the coupling between these motions can be modelled by determining the horizontal motion without reference to the vertical motion, and recovering the coupling between the motions by assuming that the vertical action is adiabatically conserved as the star oscillates horizontally. Here, we

Analytical theories for near coplanar and polar circumbinary orbits

The recently discovered Kepler circumbinary systems and the circumbinary polar-ring debris disc in the 99 Herculis system call for the study of circumbinary orbits. As an approximation, it is advisable to investigate the problem with the assumption that the outer body is massless. In such a scheme, we briefly summarize the main characteristics of the evolution of the orbits and give the general so

Comprehensive echocardiographic imaging of atrioventricular valves in children with atrioventricular septal defect : Accuracy of 2D and 3D imaging and reasons for disagreement

OBJECTIVE: To compare the accuracy and reasons for disagreement of two-dimensional (2D) and three-dimensional (3D) echocardiography findings in the assessment of the atrioventricular valve complex in patients with atrioventricular septal defect. METHODS: A total of 20 children (mean age 8 months) with atrioventricular septal defect were enrolled prospectively into this study. The accuracy of and t

Non-binary phase gratings for x-ray imaging with a compact Talbot interferometer

X-ray imaging using a Talbot-Lau interferometer, consisting of three binary gratings, is a well-established approach to acquire x-ray phase-contrast and dark-field images with a polychromatic source. However, challenges in the production of high aspect ratio gratings limit the construction of a compact setup for high x-ray energies. In this study we consider the use of phase gratings with triangul

Out-of-hospital cardiac arrest at place of residence is associated with worse outcomes in patients admitted to intensive care : a post-hoc analysis of the Targeted Temperature Management trial

BACKGROUND: The majority of out-of-hospital cardiac arrests (OHCAs) occur at place residence, which is associated with worse outcomes in unselected prehospital populations. Our aim was to investigate whether location of arrest was associated with outcome in a selected group of initial survivors admitted to intensive care.METHODS: This is a post-hoc analysis of the Targeted Temperature Management a

Geochemical composition of Baltic benthic foraminifera collected and cultured over a large salinity gradient.

Some of the most significant challenges in paleoclimate research arise from the need to both understand and reduce the uncertainty associated with proxies for climate reconstructions. These challenges were further highlighted in connection with the IODP Exp.347 Baltic Sea Paleoenvironment. We have investigated temperature and salinity proxies through a combination of field-and culture-based benthi

Inorganic Ions Assisted Anisotropic Growth of CsPbCl3 Nanowires with Surface Passivation Effect

All-inorganic halide perovskite nanowires (NWs) exhibit improved thermal and hydrolysis stability and could thus play a vital role in nanoscale optoelectronics. Among them, blue-light-based devices are extremely limited because of the lack of a facile method to obtain high-purity CsPbCl3 NWs. Herein, we report a direct and facile method for the synthesis of CsPbCl3 NWs assisted by inorganic ions t

Surface Engineering of Quantum Dots for Remarkably High Detectivity Photodetectors.

Ternary alloyed CdSexTe1–x colloidal QDs trap-passivated by iodide-based ligands (TBAI) are developed as building blocks for UV–NIR photodetectors. Both the few surface traps and high loading of QDs are obtained by in situ ligand exchange with TBAI. The device is sensitive to a broad wavelength range covering the UV–NIR region (300–850 nm), showing an excellent photoresponsivity of 53 mA/W, a fast
