Dual-modal split-type immunosensor for sensitive detection of microcystin-LR: enzyme-induced photoelectrochemistry and colorimetry.

Microcystins, the lethal cyanotoxins from microcystis aeruginosa, can inhibit the activity of protein phosphatase and promote liver tumor. Herein, a dual-modal split-type immunosensor was constructed to detect microcystin-LR (MC-LR), basing on the photocurrent change of CdS/ZnO hollow nanorod arrays (HNRs) and the blue-shift of surface plasmon resonance peak from Au nanobipyramids@Ag. By using mesoporous silica nanospheres as the carrier to immobilize second-ary antibody and DNA primer, hybridization chain ...


A Deep Multi-Modal CNN for Multi-Instance Multi-Label Image Classification.

Deep Convolutional Neural Networks (CNNs) have shown superior performance on the task of single-label image classification. However, the applicability of CNNs to multilabel images still remains an open problem, mainly because of two reasons. First, each image is usually treated as an inseparable entity and represented as one instance, which mixes the visual information corresponding to different labels. Second, the correlations amongst labels are often overlooked. To address these limitations, we propose a ...

Measurement of differential modal group delay of a few-mode fiber using a Fourier domain mode-locked laser.

We propose and experimentally demonstrate a method for measuring the differential modal group delay (DMGD) of a few-mode fiber using a Fourier domain mode-locked laser (FDML). We use the fast frequency-swept, wavelength-tunable output of the FDML in order to perform time domain measurements of interference of the modes, which is further postprocessed to extract the DMGD. We demonstrate the measurement of DMGD for a commercial two-mode fiber over the C-band. This method is not limited by the magnitude of DMG...

Gait analysis for the patients with lower limb motor dysfunction is a useful tool in assisting clinicians for diagnosis, assessment, and rehabilitation strategy making. Implementing accurate automatic gait analysis for the hemiparetic patients after stroke is a great challenge in clinical practice. This study is to develop a new automatic gait analysis system for qualitatively recognizing and quantitatively assessing the gait abnormality of the post-stroke hemiparetic patients. Twenty-one post-stroke patien...

Ultrasmall endogenous biopolymer nanoparticles for magnetic resonance/photoacoustic dual-modal imaging-guided photothermal therapy.

Multi-modal imaging-guided photothermal therapy (PTT) has aroused extensive attention in biomedical research recently because it can provide more comprehensive information for accurate diagnosis and treatment. In this research, the manganese ion chelated endogenous biopolymer melanin nanoparticles were successfully prepared for magnetic resonance (MR)/photoacoustic (PA) dual-modal imaging-guided PTT. The obtained nanoparticles with an ultrasmall size of about 3.2 nm exhibited negligible cytotoxicity, high r...

Attentional reorienting triggers spatial asymmetries in a search task with cross-modal spatial cueing.

Cross-modal spatial cueing can affect performance in a visual search task. For example, search performance improves if a visual target and an auditory cue originate from the same spatial location, and it deteriorates if they originate from different locations. Moreover, it has recently been postulated that multisensory settings, i.e., experimental settings, in which critical stimuli are concurrently presented in different sensory modalities (e.g., visual and auditory), may trigger asymmetries in visuospatia...

Behavioral phenotyping of calcium channel (CACN) subunit α2δ3 knockout mice: Consequences of sensory cross-modal activation.

Sensory cross-activation is still ill-defined and research concerning the consequences of sensory mergence on normal brain function is very limited. Human studies describe behavioral benefits of people with synesthesia- a peculiar form of perception possibly due to cross-modal activation- regarding sensory and memory abilities. Here, we studied behavioral alterations in calcium channel (CACN) subunit α2δ3 knockout (KO) mice exhibiting pain-induced cortical cross-modal activation. Knockout mice exhibited a...

Decreased electrogustometric taste sensitivity in patients with acquired olfactory dysfunction.

Cross-modal chemosensory dysfunction between olfaction and gustation is not well known.

The role of visual experience in the emergence of cross-modal correspondences.

Cross-modal correspondences describe the widespread tendency for attributes in one sensory modality to be consistently matched to those in another modality. For example, high pitched sounds tend to be matched to spiky shapes, small sizes, and high elevations. However, the extent to which these correspondences depend on sensory experience (e.g. regularities in the perceived environment) remains controversial. Two recent studies involving blind participants have argued that visual experience is necessary for ...

Effects of Nutritional Prehabilitation, With and Without Exercise, on Outcomes of Patients Who Undergo Colorectal Surgery: a Systematic Review and Meta-analysis.

Although there have been meta-analyses of the effects of exercise prehabilitation on patients undergoing colorectal surgery, little is known about the effects of nutrition-only (oral nutritional supplements and/or counseling) and multi-modal (oral nutritional supplements and/or counseling with exercise) prehabilitation on clinical outcomes and patient function after surgery. We performed a systemic review and meta-analysis to determine the individual and combined effects of nutrition-only and multi-modal pr...

Label Consistent Matrix Factorization Hashing for Large-Scale Cross-Modal Similarity Search.

Multimodal hashing has attracted much interest for cross-modal similarity search on large-scale multimedia data sets because of its efficiency and effectiveness. Recently, supervised multimodal hashing, which tries to preserve the semantic information obtained from the labels of training data, has received considerable attention for its higher search accuracy compared with unsupervised multimodal hashing. Although these algorithms are promising, they are mainly designed to preserve pairwise similarities. Th...

The as-synthesized hydrophobic CuBiSNPs are modified with DSPE-PEG/DSPE-PEG-NH, followed by the conjugation of the photosensitizer chlorin e6 (Ce6) and the target ligand folic acid (FA). The introduced Ce6 can f...

Renal-clearable quaternary chalcogenide nanocrystal for photoacoustic/magnetic resonance imaging guided tumor photothermal therapy.

Ultrasmall Cu2ZnSnS4 (CZTS) nanocrystals with high near infrared (NIR) photothermal conversion abilities and peroxidase-mimic properties are synthesized and functionalized with bovine serum albumin (BSA) for rapid clearance multifunctional theranostic platform. Due to the presence of Cu (I) of CZTS@BSA, H2O2 could be decomposed to produce highly reactive oxygen species (ROS), catalyzed by intrinsic peroxidase like activity of CZTS. The CZTS@BSA possesses high NIR absorption and excellent photoacoustic (PA) ...

A cross-modal effect of noise: the disappearance of the alarm reaction of a freshwater fish.

Anthropogenic noise pollution is recognized as a major global stressor of animals. While many studies have assessed the unimodal impacts of noise pollution with a focus on intraspecific acoustic communication, little is known about noise pollution on the perception of visual and chemical information. The 'distracted prey hypothesis' posits that processing noise interferes with processing other information in the brain. Here, we found evidence for such a cross-modal effect of noise on the antipredator behavi...

Highly Crystalline Multicolor Carbon Nanodots for Dual-Modal Imaging-Guided Photothermal Therapy of Glioma.

Imaging-guided site-specific photothermal therapy (PTT) of glioma and other tumors in central nervous system (CNS) presents a great challenge for the current nanomaterial design. Herein, an in-situ solid-state transformation method was developed for the preparation of multicolor highly crystalline carbon nanodots (HCCDs). The synthesis yields 6-8 nm sized HCCDs containing a highly crystalline carbon nanocore and a hydrophilic surface, which therefore simultaneously provide strong photoacoustic and photother...

Organic Semiconducting Photoacoustic Nanodroplets for Laser-Activatable Ultrasound Imaging and Combinational Cancer Therapy.

Combination of photoacoustic (PA) and ultrasound (US) imaging offers high spatial resolution images with deep tissue penetration, which shows great potentials in applications in medical imaging. Development of PA/US dual-contrast agents with high contrast and excellent biocompatible is of great interest. Herein, an organic semiconducting photoacoustic nanodroplet, PS-PDI-PAnD, is developed by stabilizing low-boiling-point perfluorocarbon (PFC) droplet with a photoabsorber and photoacoustic agent of perylene...

Prevailing theories of consciousness are challenged by novel cross-modal associations acquired between subliminal stimuli.

While theories of consciousness differ substantially, the 'conscious access hypothesis', which aligns consciousness with the global accessibility of information across cortical regions, is present in many of the prevailing frameworks. This account holds that consciousness is necessary to integrate information arising from independent functions such as the specialist processing required by different senses. We directly tested this account by evaluating the potential for associative learning between novel pai...

Awareness of Medical Fitness to Drive Guidelines among Occupational Physicians and Psychiatrists.

Irrespective of national guidelines for medical fitness to drive, this study investigated the cumulative expert wisdom of clinicians regarding minimum periods of driving cessation required for patients suffering from conditions that can impair driver capability. Occupational Physicians (196) and Psychiatrists (103) completed an online questionnaire. For private motorists, the modal response for anxiety and depression favoured clinical discretion, followed by three month cessations for hypomania, acute psych...

Better than Optimal.

Using a novel visual-tactile paradigm in rats, Nikbakht et al. (2018) describe multisensory behavior that outperformed predictions of optimal cue combination (indicating cross-modal synergy) and exposed encoding in PPC neurons (of stimulus and choice signals) that was independent of stimulus modality.

Trajectories of resilience and dysfunction following potential trauma: A review and statistical evaluation.

Given the rapid proliferation of trajectory-based approaches to study clinical consequences to stress and potentially traumatic events (PTEs), there is a need to evaluate emerging findings. This review examined convergence/divergences across 54 studies in the nature and prevalence of response trajectories, and determined potential sources of bias to improve future research. Of the 67 cases that emerged from the 54 studies, the most consistently observed trajectories following PTEs were resilience (observed ...

Robust subthreshold cross-modal modulation of auditory response by cutaneous electrical stimulation in first- and higher-order auditory thalamic nuclei.

Conventional extracellular recording has revealed cross-modal alterations of auditory cell activities by cutaneous electrical stimulation of the hindpaw in first- and higher-order auditory thalamic nuclei (Donishi et al., 2011). Juxta-cellular recording and labeling techniques were used in the present study to examine the cross-modal alterations in detail, focusing on possible nucleus and/or cell type-related distinctions in modulation. Recordings were obtained from 80 cells of anesthetized rats. Cutaneous ...

Green as a cbemcuru: modal as well as amodal color cues can help to solve anagrams.

Embodied cognition theories have been getting much support in recent years from studies showing that multimodal experiential traces are activated during language comprehension. However, there are almost no studies examining this influence in the opposite direction. Here, we investigated the influence of modal (physical color patch) and amodal (color word) cues on anagram solving times. We manipulated the association between the color cue and the solution word's referent color (e.g., finding the solution wor...
