Catalytic chemistry of glucose oxidase in cancer diagnosis and treatment.

Glucose oxidase (GOx) is an endogenous oxido-reductase that is widely distributed in living organisms. Over recent years, GOx has attracted increasing interest in the biomedical field due to its inherent biocompatibility, non-toxicity, and unique catalysis against β-d-glucose. GOx efficiently catalyzes the oxidization of glucose into gluconic acid and hydrogen peroxide (H2O2), which can be employed by various biosensors for the detection of cancer biomarkers. Various cancer therapeutic strategies have also...


Graph-Based Blind Image Deblurring From a Single Photograph.

Blind image deblurring, i.e., deblurring without knowledge of the blur kernel, is a highly ill-posed problem. The problem can be solved in two parts: i) estimate a blur kernel from the blurry image, and ii) given an estimated blur kernel, de-convolve the blurry input to restore the target image. In this paper, we propose a graph-based blind image deblurring algorithm by interpreting an image patch as a signal on a weighted graph. Specifically, we first argue that a skeleton image-a proxy that retains the st...

Modal area statistics for transverse Anderson localization in disordered optical fibers.

We introduce the mode-area probability density function (MA-PDF) as a powerful tool to study transverse Anderson localization (TAL), especially for highly disordered optical fibers. The MA-PDF encompasses all the relevant statistical information on TAL; it relies solely on the physics of the disordered system and is independent of the shape of the external excitation. We explore the scaling of the MA-PDF with the transverse dimensions of the system and show that it converges to a terminal form for structure...


Filtration of Sub-3.3 nm Tungsten Oxide Particles Using Nanofibrous Filters.

This work aims to understand the effects of particle concentration on the filtration of nanoparticles using nanofibrous filters. The filtration efficiencies of triple modal tungsten oxide (WO) nanoparticles were experimentally determined at three different concentrations for the size range of 0.82⁻3.3 nm in diameter. All tests were conducted using polyvinyl alcohol (PVA) nano-fibrous filters at an air relative humidity of 2.9%. Results showed that the filtration efficiencies of sub-3.3 nm nanoparticles de...

Two-pore channels and disease.

Two-pore channels (TPCs) are Ca-permeable endo-lysosomal ion channels subject to multi-modal regulation. They mediate their physiological effects through releasing Ca from acidic organelles in response to cues such as the second messenger, NAADP. Here, we review emerging evidence linking TPCs to disease. We discuss how perturbing both local and global Ca changes mediated by TPCs through chemical and/or molecular manipulations can induce or reverse disease phenotypes. We cover evidence from models of Parkins...

Dendritic Ca2+ dynamics and multi-modal processing in a cricket antennal interneuron.

The integration of stimuli of different modalities is fundamental to information processing within the nervous system. A descending interneuron in the cricket brain, with prominent dendrites in the deutocerebrum, receives input from three sensory modalities: touch of the antennal flagellum, strain of the antennal base, and visual stimulation. Using calcium imaging, we demonstrate that each modality drives a Ca2+ increase in a different dendritic region. Moreover, touch of the flagellum is represented in a t...

A multi-modal recruitment strategy using social media and internet-mediated methods to recruit a multidisciplinary, international sample of clinicians to an online research study.

Challenges exist in recruiting an international sample of clinicians and researchers to an online survey. Traditional recruitment methods remain relevant but issues such as narrow geographical reach, high cost and time intensity limit what can be achieved when aiming to recruit an international, multi-disciplinary sample. Internet-mediated and social media approaches to recruitment and engagement offer new, untested ways of capitalizing upon existing professional networks.

Broadband TE-pass slot waveguide polarizer using an asymmetrical directional coupler.

A compact TE-pass polarizer for silicon-based slot waveguides is numerically proposed based on a directional coupler where an asymmetrical slot waveguide (ASW) and hybrid plasmonic waveguide (HPW) are involved. The input section is linearly tapered to an ASW to markedly enlarge the modal birefringence. Beneficially, only the TM mode can be coupled into the adjacent HPW and attenuated while the injected TE mode just passes through the slot waveguide without coupling by properly choosing the dimensions. As a ...

Outpatient Total Knee Arthroplasty: Re-Admission and Complication Rates on Day 30 in 61 Patients.

Total knee arthroplasty (TKA) on an outpatient basis is controversial due to concerns about patient safety. In France, only 1.1% of TKAs performed in 2017 were outpatient procedures. Nevertheless, recent advances in the multi-modal and multi-disciplinary management of TKA patients combined with optimisation of the various components of peri-operative care are increasing the use of outpatient TKA. However, studies on outcomes remain scarce. The primary objective of this work was to compare re-admission rates...

Comprehensive, multi-modal characterization of an imiquimod-induced human skin inflammation model for drug development.

Imiquimod (IMQ) is often used as topical challenge agent to provoke local skin inflammation. The objective of this study was to develop and refine a rapid, temporary and reversible human skin inflammation model with IMQ for application in clinical drug development. A randomized, vehicle-controlled, open-label, dose-ranging study was conducted in 16 healthy male subjects. IMQ (5 mg) was applied once daily for 72h under occlusion to intact skin (n = 8) or tape stripped (TS) skin (n = 8). Although IMQ alone in...

Broadband and low-loss mode scramblers using CO-laser inscribed long-period gratings.

We demonstrate broadband and low-loss three-mode and six-mode scramblers employing CO-laser inscribed long-period gratings (LPGs) for space-division multiplexing. Step-index (SI) few-mode fibers are used to avoid mode coupling to the cladding modes. We characterize the mode scramblers using a swept-wavelength interferometer. Mode-dependent loss (MDL) and modal transfer matrices over the C+L band are presented. Demonstrated LPGs with negligible MDL and low insertion loss contributed to high-performance CO-la...

Multi-wavelength add-drop filter with phase-modulated shifted Bragg grating.

We present, for the first time to the best of our knowledge, a multichannel add-drop operation with a phase-modulated shifted Bragg grating based filter. The device is realized in a silicon-on-insulator waveguide platform with TiO as a coating material to reduce the refractive index contrast. The operation is shown for three and five wavelength channels within the telecom C-band. A line width of 0.6 nm with an extinction ratio of 20 dB is achieved. The shifted Bragg grating is modulated maintaining a moda...

Audiovisual perception in amblyopia: A review and synthesis.

Amblyopia is a common developmental sensory disorder that has been extensively and systematically investigated as a unisensory visual impairment. However, its effects are increasingly recognized to extend beyond vision to the multisensory domain. Indeed, amblyopia is associated with altered cross-modal interactions in audiovisual temporal perception, audiovisual spatial and motion perception, and audiovisual speech perception. Furthermore, although the visual impairment in amblyopia is typically unilateral,...

Biocompatible sphere, square prism and hexagonal rod GdO:Eu@SiO nanoparticles: The effect of morphology on multi-modal imaging.

The cubic structure GdO:Eu@SiO particles with homogeneous multiform morphologies (pH 6: sphere, pH 10: square prism and pH 12: hexagonal rod) were prepared by pH modifiers: nitric acid- and ammonium hydroxide-assisted solvothermal reaction. The effect of synthesis conditions (reaction time and pH value) on the morphology and the particle growth mechanisms were researched. The photoluminescence (PL), magnetic resonance imaging (MRI) and X-ray computed tomography (CT) studies of GdO:Eu@SiO showed strong depen...

Ultra-broadband tunable single- and double-mode InAs/InP quantum dot external-cavity laser emitting around 1.65  μm.

We report an ultra-wide tunable single- and double-mode InAs/InP quantum dot (QD) external-cavity (EC) laser in a Littrow configuration. By combining the high modal gain of the QD material in the long wavelength range and an anti-reflection/high-reflection facet coating, the entire single-mode tuning range was increased up to 190 nm under a relatively low constant pulsed injection current. Furthermore, the tunable range was further increased to 230 nm at different bias currents. In addition, a mode spacin...

Phase-shift evolution of the thermally-induced refractive index grating in high-power fiber laser systems induced by pump-power variations.

A phase shift between the modal interference pattern and the thermally-induced refractive index grating is most likely the ultimate trigger for the damaging effect of transverse mode instabilities (TMI) in high-power fiber laser systems. By using comprehensive simulations, the creation and evolution of a thermally-induced phase shift is explained and illustrated in detail. It is shown that such a phase shift can be induced by a variation of the pump power. The gained knowledge about the generation and evolu...

Energy exchanges at contact events guide sensorimotor integration across intermodal delays.

The brain must consider the arm's inertia to predict the arm's movements elicited by commands impressed upon the muscles. Here, we present evidence suggesting that the integration of sensory information leading to the representation of the arm's inertia does not take place continuously in time but only at discrete transient events, in which kinetic energy is exchanged between the arm and the environment. We used a visuomotor delay to induce cross-modal variations in state feedback and uncovered that the dif...

Ultra-broadband and compact graphene-on-silicon integrated waveguide mode filters.

Increasing bandwidth demands in optical communications necessitates the introduction of mode-division multiplexing (MDM) on top of the existing wavelength-division multiplexing (WDM) systems. Simultaneous management of both multiplexing systems will be a complex task, and there is the possibility of signal degradation through modal crosstalk. Here, we propose graphene-on-silicon (GOS) integrated waveguide mode filters to suppress the propagation of spurious waveguide modes at the telecommunications waveleng...

Mechanisms of active control of sound radiation from an opening with boundary installed secondary sources.

Previous work has demonstrated that installing secondary sources at the edge of a cavity opening can reduce sound radiation through it, but the mechanisms are not clear, which is investigated in this paper by using the modal decomposition method. It is found that a double layer edge system achieves better performance than a single layer system because secondary sources at the edge of the same layer cannot excite some modes effectively and those at different heights compensate this. There exists an upper lim...

Dual T and T Weighted Magnetic Resonance Imaging Based On Gd Loaded Bioinspired Melanin Dots.

In this report, a novel T/T dual modal nanoprobe based on highly efficient and bioinspired melanin dots (M-dots) with directly loading gadolinium (Gd-M-dots) for magnetic resonance imaging (MRI) is described. In vitro and in vivo investigations have revealed that Gd-M-dots showed nontoxicity and good biocompatibilitity. Gd-M-dots relaxivity values on 3 T were determined to be r=23.4 and r=123.3mMs, which were much higher than both Gd-DTPA (r=5.1, r=6.2mMs) and Fe-M-dots (r=1.2, r=2.1mMs). For in vivo MRI, a...

Audio-tactile cues from an object's fall change estimates of one's body height.

When we drop an object from our hands, we use internal models of both our body height and object-motion to predict when it will hit the floor. What happens if the sensory feedback finally received from the impact conflicts with this prediction? The present study shows that such conflict results in changes in the internal estimates of our body height: When the object people dropped takes longer than expected to hit the floor, they report feeling taller and behave as if their legs were longer. This provides t...

Successful multi-modal treatment of grade IV lymphedema in lymphatic filariasis: A case study.

We present an integrated therapeutic approach performed on a 37 year old female with giant lymphedema (Grade IV) due to lymphatic filariasis of 27 years duration. Our therapeutic approaches consisted of a basic foot care program for two weeks, followed by a course of oral penicillin for a week including conservative treatment with complete decongestive therapy (CDT) together with respiratory physiotherapy and walking exercises. In addition, advanced surgical techniques with supra-fascial excision of alterna...

A multi-modal MRI study of the central response to inflammation in rheumatoid arthritis.

It is unknown how chronic inflammation impacts the brain. Here, we examined whether higher levels of peripheral inflammation were associated with brain connectivity and structure in 54 rheumatoid arthritis patients using functional and structural MRI. We show that higher levels of inflammation are associated with more positive connections between the inferior parietal lobule (IPL), medial prefrontal cortex, and multiple brain networks, as well as reduced IPL grey matter, and that these patterns of connectiv...

Enhancing noise-induced switching times in systems with distributed delays.

The paper addresses the problem of calculating the noise-induced switching rates in systems with delay-distributed kernels and Gaussian noise. A general variational formulation for the switching rate is derived for any distribution kernel, and the obtained equations of motion and boundary conditions represent the most probable, or optimal, path, which maximizes the probability of escape. Explicit analytical results for the switching rates for small mean time delays are obtained for the uniform and bi-modal ...

A Flexible Caterpillar-Like Gold Nanoparticle Assemblies with Ultrasmall Nanogaps for Enhanced Dual-Modal Imaging and Photothermal Therapy.

Gold nanoparticle (AuNP) assemblies (GNAs) have attracted attention since enhanced coupling plasmonic resonance (CPR) emerged in the nanogap between coupling AuNPs. For one dimensional GNAs (1D-GNAs), most CPR from the nanogaps could be easily activated by electromagnetic waves and generate drastically enhanced CPR because the nanogaps between coupling AuNPs are linearly distributed in the 1D-GNAs. The reported studies focus on the synthesis of 1D-GNAs and fundamental exploration of CPR. There are still pro...
