It is now widely recognized that the isolation of circulating tumor cells based on cell surface markers might be hindered by variability in their protein expression. Especially in pancreatic cancer, isolation based only on EpCAM expression has produced very diverse results. Methods that are independent of surface markers and therefore independent of phenotypical changes in the circulating cells might increase CTC recovery also in pancreatic cancer. We compared an EpCAM-dependent (IsoFlux) and a size-dependent (automated Siemens Healthineers filtration device) isolation method for the enrichment of pancreatic cancer CTCs...

Evdokia Pilavaki, Andreas Demosthenous
Detection and control of infectious diseases is a major problem, especially in developing countries. Lateral flow immunoassays can be used with great success for the detection of infectious diseases. However, for the quantification of their results an electronic reader is required. This paper presents an optimized handheld electronic reader for developing countries. It features a potentially low-cost, low-power, battery-operated device with no added optical accessories. The operation of this proof of concept device is based on measuring the reflected light from the lateral flow immunoassay and translating it into the concentration of the specific analyte of interest...

We report spectral splitting behaviors based on Fano resonances in a novel simple planar metasurface composed of gold nanobars and nanorings. Multiple plasmonic modes and sharp Fano effects are achieved in a broadband transmittance spectrum by exploiting the rotational symmetry of the metasurface. The transmission properties are effectively modified and tuned by modulating the structural parameters. The highest single side Q-factor and FoM which reaches 196 and 105 are observed at Fano resonances. Our proposed design is relatively simple and can be applied for various applications such as multi-wavelength highly sensitive plasmonic sensors, switching, and slow light devices...

With the widespread use of electric machines, there is a growing need to extract information from the machines to improve their control systems and maintenance management. The present work shows the development of an embedded system to perform the monitoring of the rotor physical variables of a squirrel cage induction motor. The system is comprised of: a circuit to acquire desirable rotor variable(s) and value(s) that send it to the computer; a rectifier and power storage circuit that converts an alternating current in a continuous current but also stores energy for a certain amount of time to wait for the motor's shutdown; and a magnetic generator that harvests energy from the rotating field to power the circuits mentioned above...

Recently, consumer applications have dramatically created the demand for low-cost and compact gyroscopes. Therefore, on the basis of microelectromechanical systems (MEMS) technology, many gyroscopes have been developed and successfully commercialized. A MEMS gyroscope consists of a MEMS device and an electrical circuit for self-oscillation and angular-rate detection. Since the MEMS device and circuit are interactively related, the entire system should be analyzed together to design or test the gyroscope. In this study, a MEMS vibratory gyroscope is analyzed based on the system dynamic modeling; thus, it can be mathematically expressed and integrated into a circuit simulator...

The cells of the vascular system are highly sensitive to biophysical cues from their local cellular microenvironment. To engineer improved materials for vascular devices and delivery of cell therapies, a key challenge is to understand the mechanisms that cells use to sense biophysical cues from their environment. Syndecans are heparan sulfate proteoglycans (HSPGs) that consist of a protein core modified with heparan sulfate glycosaminoglycan chains. Due to their presence on the cell surface and their interaction with cytoskeletal and focal adhesion associated molecules, cell surface proteoglycans are well poised to serve as mechanosensors of the cellular microenvironment...

Knowledge of the microscopic elemental composition of multinary III/V semiconductor materials is crucial to the development of functionalized opto-electronic devices. Well-proven composition analysis methods, such as high resolution X-ray diffraction (HRXRD), fail to determine the elemental composition when more than three atomic species are involved. In this work we propose a procedure for the composition analysis of multinary III/V semiconductors at atomic resolution using high angle annular dark field (HAADF) scanning transmission electron microscopy (STEM) image simulations...

Justin Tsai, David I Pedowitz
Total ankle arthroplasty is an increasingly popular procedure to address tibiotalar joint arthritis. Implant design and the rationale behind it have changed throughout the years. Newer generation implants allow for minimal resection of bone and use fixed-bearing technology. Long-term follow-up multicenter studies will determine the lifetime of these devices and their effectiveness in addressing pain and improving function for patients with endstage tibiotalar arthritis.

Limb deformity correction has been widely discussed in orthopedic literature with an increasing interest in technologically based surgical strategies. However, principles described by Ilizarov and Paley still form the basis of these newly developing surgical systems. The recent advances and increased use of computers and mobile devices in the medical arena, along with the application of dynamic hexapod external fixation, have allowed for easier and more convenient strategies, leading to a greater outreach and more confidence in the newer surgeon when faced with addressing a patient with a limb deformity...

Venous thromboembolism (VTE) is a common complication after total hip arthroplasty (THA) and total knee arthroplasty (TKA), occurring in up to 85% of patients who are not treated with prophylaxis. The initiation of VTE development may occur intraoperatively. This study investigated whether this gap in VTE prophylaxis can be addressed by the use of intraoperative intermittent pneumatic compression devices (IPCDs) and if intraoperative IPCDs have a meaningful benefit in preventing symptomatic VTE. The authors defined symptomatic VTE as deep venous thrombosis in either lower extremity or a pulmonary embolism...

OBJECTIVES: Meta-analyses from observational and randomized studies have demonstrated benefits of off-pump surgery for hard and surrogate endpoints. In some of them, increased re-revascularization was noted in the off-pump groups, which could impact their long-term survival. Therefore, we analyzed the course of all patients undergoing isolated coronary surgery regarding the major cardiac and cerebrovascular event (MACCE) criteria. METHODS: A prospective register was taken from a high-volume off-pump center recording all anaortic off-pump (ANA), clampless off-pump (PAS-Port) and conventional (CONV) coronary artery bypass operations between July 2009 and June 2015...
