Clinical studies indicate that thrombocytopenia correlates with the development of severe falciparum malaria, suggesting that platelets either contribute to control of parasite replication possibly as innate parasite killer cells or function in eliciting pathogenesis. Removal of platelets by anti-CD41 mAb treatment, platelet inhibition by aspirin, and adoptive transfer of WT platelets to CD40-KO mice, which do not control parasite replication, resulted in similar parasitemia compared with control mice. Human platelets at a physiological ratio of 1 platelet to 9 RBCs did not inhibit the in vitro development or replication of blood-stage P...

Unstable vertebral body fragility fractures of the thoracolumbar spine can occur with or without relevant trauma. Initially, a standardized diagnostic algorithm including magnetic resonance tomography is recommended to detect accompanied further vertebral body fractures, to interpret the individual fracture stability, and to screen for relevant traumatic intervertebral disc lesions. Aim of the therapy is to assure fast mobilization and to maintain spinal alignment. Unstable fracture morphology is defined by vertebral body fractures including a relevant defect of the posterior vertebral cortex as well as type B or C fractures...

The creation of communication interfaces between abiotic and biotic systems represents a significant research challenge. In this work, we design and model a system linking the biochemical signaling pathways of mammalian cells to the actions of a mobile robotic prosthesis. We envision this system as a robotic platform carrying an optically monitored bioreactor that harbors mammalian cells. The cellular, optical signal is captured by an onboard fluorescent microscope and converted into an electronic signal. We first present a design for the overall cell-robot system, with a specific focus on the design of the synthetic gene networks needed for the system...

BACKGROUND: In this study, we sought to analyze the incidence and relevance of von Willebrand factor (VWF) abnormalities in patients undergoing transcatheter aortic valve implantation (TAVI), especially on perioperative bleeding. Furthermore, we hypothesized that, similar to aortic valve surgery, TAVI results in a restoration of VWF abnormalities. METHODS AND RESULTS: We performed a prospective analysis of periinterventional VWF parameters in 74 patients (80±7years, female in 37...

Cell-type specific and inducible alternative splicing has a fundamental impact on regulating gene expression and cellular function in a variety of settings including activation and differentiation. We have recently shown that activation-induced skipping of TRAF3 exon 8 activates non-canonical NFkB signaling upon T cell stimulation, but the regulatory basis for this splicing event remains unknown. Here we identify cis- and trans-regulatory elements rendering this splicing switch activation-dependent and cell-type specific...

We investigate the role of transition metal atoms of group V-b (V, Nb, and Ta) and VI-b (Cr, Mo, and W) as n- or p-type dopants in anatase TiO2 using thermodynamic principles and density functional theory with the Heyd-Scuseria-Ernzerhof HSE06 hybrid functional. The HSE06 functional provides a realistic value for the band gap, which ensures a correct classification of dopants as shallow or deep donors or acceptors. Defect formation energies and thermodynamic transition levels are calculated taking into account the constraints imposed by the stability of TiO2 and the solubility limit of the impurities...

Cardiac volume/function assessment remains a critical step in daily cardiology and 3D ultrasound plays an increasingly important role. Though development of automatic endocardial segmentation methods has received much attention, the same cannot be said about epicardial segmentation, in spite of the importance of full myocardial segmentation. In this study, different ways of coupling the endo- and epicardial segmentation are contrasted and compared to uncoupled segmentation. For this purpose, the B-spline Explicit Active Surfaces framework was used...

BACKGROUND: Aneurysmal bone cysts (ABC) are rapidly growing benign osseous lesions composed of blood-filled channels separated by fibrous septa. Since the value of external beam radiotherapy (EBRT) for ABC has not been well defined, the German Cooperative Group on Radiotherapy for Benign Diseases performed the national register study described herein. PATIENTS AND METHODS: Five German institutions collected data regarding clinical features, treatment concepts, and outcome for patients with ABC who had been referred for local EBRT over the past 30 years...

This article presents the rare case of a boy who was born in our hospital with valgus deformity and external rotation of the right lower leg because of congenital patellar dislocation. In the case presented a stable repositioning of the patella could be achieved by redressment with a plaster cast and leg brace. During a 4-year follow-up there were no tendencies towards dislocation during the clinical examination and no dislocation events were documented. In selected cases an attempt at conservative repositioning and retention treatment appears to be worthwhile before surgical treatment is indicated...

Organisms use endogenous clocks to anticipate regular environmental cycles, such as days and tides. Natural variants resulting in differently timed behaviour or physiology, known as chronotypes in humans, have not been well characterized at the molecular level. We sequenced the genome of Clunio marinus, a marine midge whose reproduction is timed by circadian and circalunar clocks. Midges from different locations show strain-specific genetic timing adaptations. We examined genetic variation in five C. marinus strains from different locations and mapped quantitative trait loci for circalunar and circadian chronotypes...

Domain boundaries are hypothesized to play a role in the crystalline to amorphous transition. Here we examine domain boundary structures in comparison to crystalline and amorphous structures in bilayer silica grown on Ru(0 0 0 1). Atomically resolved scanning probe microscopy data of boundaries in crystalline bilayer films are analyzed to determine structural motifs. A rich variety of boundary structures including rotational, closed-loop, antiphase, and complex boundaries are identified. Repeating units with ring sizes of 558 and 57 form the two most common domain boundary types...

We report the structural, electronic, magnetic, and elastic properties of a two-dimensional (2D) honeycomb stannic oxide (SnO2) monolayer based on comprehensive first-principles calculations. The free-standing and well-ordered 2D centered honeycomb SnO2 (T-SnO2) monolayer with D3d point-group symmetry has good dynamical stability, as well as thermal stability at 500 K. The T-SnO2 monolayer is a nonmagnetic wide-bandgap semiconductor with an indirect bandgap of 2.55/4.13 eV obtained by the generalized gradient approximation with the Perdew-Burke-Ernzerhof/Heyd-Scuseria-Ernzerhof hybrid functional, but it acquires a net magnetic moment upon creation of a Sn vacancy defect...

The transverse oscillation (TO) technique can improve the estimation of tissue motion perpendicular to the ultrasound beam direction. TOs can be introduced using plane wave (PW) insonification and bi-lobed Gaussian apodisation (BA) on receive (abbreviated as PWTO). Furthermore, the TO frequency can be doubled after a heterodyning demodulation process is performed (abbreviated as PWTO*). This study is concerned with identifying the limitations of the PWTO technique in the specific context of myocardial deformation imaging with phased arrays and investigating the conditions in which it remains advantageous over traditional focused (FOC) beamforming...

BACKGROUND: Pancreatic adenocarcinoma (PDAC) incidence is increasing worldwide. Several studies have shown that lymphopenia was correlated with a poor prognosis but the potential interest to measure lymphopenia in the pre and post-operative setting as well as its added value among conventional prognostic factors was never investigated. METHODS: Data from two independent cohorts in whom patients underwent resection for pancreatic carcinoma were retrospectively recorded...

BACKGROUND: Bariatric surgery is one of the main treatments for severity obesity, but weight regain after surgery is an important issue. OBJECTIVES: To compare the clinical and nutritional profiles of good and poor weight loss responders in the late postoperative period after bariatric surgery. METHODS: A cross-sectional study with patients undergoing Roux-en-Y gastric bypass in a University Hospital. Patients were divided into good weight loss responders (GWLR) and poor weight loss responders (PWLR) defined as ≥ 50% or < 50% excess weight loss (EWL), respectively, at least 2 years post-surgery...

It was previously demonstrated in 2-D echocardiography that a proper multiline transmit (MLT) implementation can be used to increase frame rate while preserving image quality. Initial findings for extending MLT to 3-D showed that it might address the low spatiotemporal resolution of current volumetric ultrasound systems. However, to date, it remains unclear how much transmit/receive parallelization would be possible using a 3-D MLT system. Therefore, the aim of this paper was to contrast different MLT setups for 3-D imaging by computer simulation in order to determine an optimal tradeoff between the amount of parallelization of an MLT system and the corresponding signal-to-noise ratio of the resulting images...

Biomimetic robots have been used to explore and explain natural phenomena ranging from the coordination of ants to the locomotion of lizards. Here, we developed a series of decision architectures inspired by the information exchange between a host organism and its microbiome. We first modeled the biochemical exchanges of a population of synthetically engineered E. coli. We then built a physical, differential drive robot that contained an integrated, onboard computer vision system. A relay was established between the simulated population of cells and the robot's microcontroller...

Treating vertebral body fractures is challenging when there is relevant pre-existing spinal degeneration. Both vertebral body fractures and spinal degeneration are related to the physiological aging process. The increases in both are linked to increases in life expectancy. Several factors promote spinal degeneration and increase fracture risk, such as disc degeneration, spinal imbalance and osteoporosis. The main diagnostic and therapeutic challenge is to identify the sources of pain and to start appropriate therapy...

Acoustic and articulatory studies demonstrate covert contrast in perceptually neutralised phonemic contrasts in both typical children and children with speech disorders. These covert contrasts are thought to be relatively common and symptomatic of phonetic speech disorders. However, clinicians in the speech therapy clinic have had no easy way of identifying this covertness. This study uses ultrasound tongue imaging to compare tongue contours for /t/and /k/in seven children with persistent velar fronting. We present a method of overlaying tongue contours to identify covert contrast at the articulatory level...
