A mounting body of evidence in cancer research suggests that the local microenvironment tumor cells has a profound influence on progression and metastasis. In vitro studies its pharmacological modulation, however, are often hampered by technical challenges associated with creating physiological cell culture environments integrate key components their native niche such as neighboring extracellular matrix (ECM) to mimic complex microarchitecture cancerous tissue. Using early-stage breast model...
Diffuse optical tomography (DOT) has been investigated as an alternative imaging modality for breast cancer detection thanks to its excellent contrast hemoglobin oxidization level. However, due the complicated non-linear photon scattering physics and ill-posedness, conventional reconstruction algorithms are sensitive parameters such boundary conditions. To address this, here we propose a novel deep learning approach that learns obtains accurate three dimensional (3D) distribution of...
Abstract Aryl hydrocarbon receptor (AhR) antagonism can mitigate cellular damage associated with cerebral ischaemia and reperfusion (I/R) injury. This study investigated the neuroprotective effects of AhR antagonist administration before in a rat stroke model influence timing on its effects. Magnetic resonance imaging (MRI) was performed at baseline, immediately after, 3, 8, 24 h after sham, control (I/R injury), TMF10 (trimethoxyflavone [TMF] administered 10 min post-ischaemia), TMF50 (TMF...
Emerging evidence has suggested that hydrogen sulfide (H2S) may alleviate the cellular damage associated with cerebral ischemia/reperfusion (I/R) injury. In this study, we assessed using 1H-magnetic resonance imaging/magnetic spectroscopy (1H-MRI/MRS) and histologic analysis whether H2S administration prior to reperfusion neuroprotective effects. We also evaluated for differences in effects of treatment at 2 time points. 1H-MRI/MRS data were obtained baseline, 3, 9, 24 h after ischemia from...
Object detection is useful for authenticating artworks, and object methods based on deep learning have been actively studied in recent years. However, existing cannot perform well due to the lack of labeled artwork datasets. To overcome problem, we propose a novel approach artworks. The proposed consists two steps. First, apply neural style transfer images data augmentation. Second, train an method augmented dataset. We evaluate Brueghel People-Art experimental results show that our...
In this paper, we propose a new immersive virtual aquarium system that comprises enhanced navigation, shared user experience, and manipulation in reality. The utilizes large studio allows users to walk around naturally operates as surrogate for navigation the aquarium. It also provides an additional view shows what is happening observers. can be regarded form of augmented virtuality it superimposes live video avatar into addition, each interact with fishes via 3D gestures because gesture...
Even though the olfactory function usually is improved or unchanged after ethmoidectomy, some patients complain of disturbance, which may be caused by direct injury to nerves. However, detailed anatomic pathway nerves that leave mucosa and going through cribriform plate insert into bulb uncertain. In studies lateral nasal wall, we referred thin bone connects middle, superior, supreme turbinates skull base as "conchal plate." We undertook this study determine relation between conchal...
With the recent expansion of art auction market, discernment forged artworks has become increasingly vital. Studies have been conducted to detect forgeries through various means, such as physical examinations paint and canvas, well more abstract inquiries into artistic style. Among these, style-based studies faced challenges due lack relevant datasets. To address this, we constructed a dataset by manually creating both genuine oil paintings. Typically, artwork images are very large. Previous...
We present a genetic feature selection method for the optimization of an image set producing real-time photomosaics. A photomosaic is that divided into grid cells, each which replaced with another appropriate color pattern. Construction requires large tile images different patterns. However, number photo expensive pattern searching and storage space. These requirements can cause problems in applications to domains or mobile devices limited resources. building optimized accelerate minimize...
Targeting of vascular endothelial growth factor receptors (VEGFRs) has potential anti-angiogenic effects because VEGFR-2 is the major signaling regulator VEGF/VEGFR pathways. We aimed to elucidate drug mechanism and anti-tumor efficacy TTAC-0001, a novel, fully human anti-VEGFR-2/KDR monoclonal antibody, in mouse orthotopic breast cancer model using multi-modal bioimaging.We used xenograft tumor which cells (MDA-MB-231) were injected into right mammary fat pad Balb/c nude mice. investigated...
Safeguarding intangible cultural heritage such as traditional painting is getting more critical, but the conventional way to preserve has been simply record performance and explanations of Living Human Treasures using video cameras. It cannot whole procedure detailed performances human experts. In this paper, we suggest a multisensory system that captures core activities Korean while minimizing interference with their activities. The procedures by tracking three-dimensional movements painter...
We realized a real space-based virtual aquarium equipped with multiview function that provides images for users and audiences at the same time through motion tracking sensors. A reality system needs more natural intuitive interfaces so as to enhance users' immersion. attach markers on camera devices in space designed one-to-one size trace user motions, which is reflected generate world images. These are transmitted user's immersing image devices. Also, allows share experiences by providing...
<title>Abstract</title> <bold>Purpose:</bold> Gadolinium (Gd)-based contrast agents are mostly used for contrast-enhanced magnetic resonance lymphangiography (MRL). However, overcoming venous contamination issues remains challenging. This study aims to assess the MRL efficacy of newly developed iron-based agent (INV-001, Inventera Pharmaceuticals Inc., Seoul, Korea) which is specially designed mitigate issues. further endeavors explore optimal dosage, including both injection volume and...
