Although widely employed in medical diagnostic applications, most of the available commercial ultrasound (US) scanners do not always fit the needs of research users. Access to raw US data, portability, flexibility and advanced user control are essential features to explore alternative biomedical signal and imaging processing algorithms. In this paper, we present the initial results of a reconfigurable, cost-effective and modular 128-channel FPGA and PC-based US system, specifically designed for teaching and medical imaging research...

Electrode arrays for recording and stimulation in the central nervous system have enabled numerous advances in basic science and therapeutic strategies. In particular, micro-fabricated arrays with precision size and spacing offer the benefit of accessing single neurons and permit mapping of neuronal function. Similar advances are envisioned toward understanding the autonomic nervous system and developing therapies based on its modulation, but appropriate electrode arrays are lacking. Here, we present for the first time, a multi-channel electrode array suitable for penetration of peripheral nerves having diameters as small as 0...

The most commonly used method for user authentication in ICT services or systems is the application of identification tools such as passwords or personal identification numbers (PINs). The rapid development in ICT technology regarding smart devices (laptops, tablets and smartphones) has allowed also the advance of hardware components that capture several biometric traits such as fingerprints and voice. These components are aiming among others to overcome weaknesses and flaws of password usage under the prism of improved user authentication with higher level of security, privacy and usability...

The advances in recent nanofabrication techniques have facilitated explorations of metal structures into nanometer scales, where the traditional local-response Drude model with hard-wall boundary conditions fails to accurately describe their optical responses. The emerging nonlocal effects in single ultrasmall silver nanoparticles have been experimentally observed in single-particle spectroscopy enabled by the unprecedented high spatial resolution of electron energy loss spectroscopy (EELS). However, unambiguous optical observation of such new effects in gold nanoparticles has yet not been reported, due to the extremely weak scattering and the obscuring fingerprint of strong interband transitions...

Geographic and socioeconomic barriers may pose a significant difficulty in delivering home dialysis care to remote underserved populations leading to low utilization rates and poor outcomes. Telehealth may serve as a solution to overcome geographic barriers in delivering home dialysis care. Although technologic advances in telehealth have progressed rapidly making it accessible and inexpensive, it has been underused by nephrologists. Components of a regular face-to-face visit that can be successfully accomplished remotely using telehealth techniques include physician-patient communication, physical examination, laboratory and treatment data monitoring, nursing and nutrition education...

The media is an important source of health information, especially critical in rural communities with geographically-dispersed populations that are harder to reach through other channels. Yet health information is unequally distributed; these information disparities are compounded in rural areas, which may contribute to health disparities. We identify and describe health-related news in a culturally-diverse rural California county characterized by high levels of poverty, unemployment, low educational attainment, and over half of Mexican-origin...

Human adipose-derived mesenchymal stem cells (hASCs) are an ideal cell source for regenerative medicine due to their capabilities of multipotency and the readily accessibility of adipose tissue. They have been found residing in a relatively low oxygen tension microenvironment in the body, but the physiological condition has been overlooked in most studies. In light of the escalating need for culturing hASCs under their physiological condition, this review summarizes the most recent advances in the hypoxia effect on hASCs...

Genomic heterogeneity of bacterial species is observed and studied in experimental evolution experiments and clinical diagnostics, and occurs as micro-diversity of natural habitats. The challenge for genome research is to accurately capture this heterogeneity with the currently used short sequencing reads. Recent advances in NGS technologies improved the speed and coverage and thus allowed for deep sequencing of bacterial populations. This facilitates the quantitative assessment of genomic heterogeneity, including low frequency alleles or haplotypes...

Miniaturization in percutaneous surgery has seen its zenith in microperc. Technological advances have enabled us to treat renal lithiasis through a 4.8 Ch. caliper percutaneous access. According to published literature, the technique is reproducible and when applied to small and medium size renal lithiasis has a high success rate keepin a low complication rate. Its main advantage is the absence of tract dilatation, diminishing the bleeding risk inherent to percutaneous access, postoperative pain and hospital stay...

Technology, infrastructure, governmental support, and interest in mental health accessibility have led to a burgeoning field of telemental health therapy (TMHT). Psychologists can now provide therapy via computers at great distances and little cost for parties involved. Growth of TMHT within the U.S. Department of Veterans Affairs and among psychologists surveyed by the American Psychological Association (APA) suggests optimism in this provision of services (Godleski, Darkins, & Peters, 2012; Jacobsen & Kohout, 2010)...

Almost half the cells and 1% of the unique genes found in our bodies are human, the rest are from microbes; predominantly bacteria, archaea, fungi, and viruses. These microorganisms collectively form the human microbiota, with most colonizing the gut. Recent technological advances, open access data-libraries, and application of high throughput sequencing have allowed these microbes to be identified and their contribution to neurological health examined. Emerging evidence links perturbations in the gut microbiota to neurological disease, including disease risk, activity, and progression...

PURPOSE: Compared to others, patients diagnosed with lung cancer following an emergency, unplanned admission to hospital (DFEA) have more advanced disease and poorer prognosis. Little is known about DFEA patients' beliefs about cancer and its symptoms or about their help-seeking behaviours prior to admission. METHODS: As part of a larger single-centre, prospective mixed-methods study conducted in one University hospital, we undertook qualitative interviews with patients DFEA and their carers to obtain their understanding of symptoms and experiences of trying to access healthcare services before admission to hospital...

INTRODUCTION: Multiple factors and comorbidities have been implicated in the ability of arteriovenous fistulas (AVF) to mature, including vessel anatomy, advanced age, and the presence of coronary artery disease or peripheral vascular disease. However, little is known about the role of uremia on AVF primary failure. In this study, we attempt to evaluate the effect of uremia on AVF maturation by comparing AVF outcomes between pre-dialysis chronic kidney disease (CKD) stage five patients and those who had their AVF created after hemodialysis (HD) initiation...
