The interaction of tumor cells and their microenvironment is thought to be a key factor in tumor development. We present spatial RNA profiles obtained from 30 lung adenocarcinoma patients at the non-invasive and later invasive stages. We use spatial transcriptome sequencing data in conjunction with in situ RNA profiling to conduct higher resolution analyses.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a complication caused by antithyroid drugs, particularly propylthiouracil (PTU). Most patients experience organ failure due to the affects of the treatment regimen. We herein report the case of an 89-year-old woman whose severe AAV induced by PTU resulted in various instances of organ failure that eventually led to death after 9 years of PTU therapy.

The artery of Davidoff and Schechter (ADS) is mostly identified in pathological conditions such as dural arteriovenous fistulas and brain tumors. Herein, we report a rare case of a ruptured aneurysm of the ADS, which was one of the feeders of a falcotentorial dural arteriovenous fistula. We performed endovascular embolization of the aneurysm and parent artery using n-butyl-2-cyanoacrylate.

Aspirin, a nonsteroidal anti-inflammatory drug, has been proven effective in a clinical trial of carcinogenesis blockade. However, various modes of action have been reported for these effects. Thus, in this study, we aimed to present reasonable mode of actions as a proof of concept for human trials, especially trials for patients with familial adenomatous polyposis (FAP).

Through engineering the emission features emanating from a light source, source illusions enable the generation of illusions in which observers viewing at a distance misperceive the actual state of the source. However, those few efforts are significantly limited to the source transformation and metamaterials used. This limitation makes high-performance camouflaging of source emissions difficult to achieve.

Neuroblastomas are the most common extracranial solid tumors in children and have a unique feature of neuronal differentiation. Peroxisome proliferator-activated receptor (PPAR)-γ is reported to have neuroprotective effects in addition to having antitumor effects in various cancers. Thus, we aimed to clarify the role of PPAR-γ agonist and antagonist in malignant neuroblastomas, which also possess neuronal features.

Background: Clinical outcomes of Chiari pelvic osteotomy for acetabular dysplasia, including conversion to total hip arthroplasty (THA), have not been adequately explored. The purpose of this study was to examine the long-term results and clinical outcomes of Chiari pelvic osteotomy as the primary outcome and to analyze its prognostic factors as the second outcome.

Methods: This study was a multicenter, retrospective cohort study.

We report an automated cell-isolation system based on fluorescence image analysis of cell aggregates cultured in a photodegradable hydrogel. The system incorporates cell culture in a humidified atmosphere with controlled CO concentration and temperature, image acquisition and analysis, micropatterned light exposure, and cell collection by pipetting. Cell aggregates were cultured on hydrogels, and target cells were selected by phase contrast and fluorescence image analysis.

Recent remarkable developments in metamaterials and metadevices manipulating diffusive processes, such as thermal and electrical conduction, have enabled the control of multiple phenomena and the development of multifunctional devices. However, only either multiphysics operations or multiple functionalities are usually implemented on single metadevices. In this paper, we describe a method for the optimal design of metadevices that achieves both cloaking and focusing in the control of both heat flux and direct current by a single device, i.

Sex determination is a crucial factor in the identification of unidentified human remains. Sex determination by DNA analysis is particularly useful because it can be applied to samples for which morphological characteristics are unavailable. Because samples handled in forensic DNA typing are easily degraded by environmental factors and microorganisms, there is a need for a method that can accurately determine sex even in highly decayed samples.

Invasive pulmonary aspergillosis caused by the ubiquitous mold Aspergillus fumigatus is a major threat to immunocompromised patients, causing unacceptably high mortality despite standard of care treatment, and costing an estimated $1.2 billion annually. Treatment for this disease has been complicated by the emergence of azole resistant strains of A.

Background/aim: Among colorectal cancer-associated intestinal microbiota, colibactin-producing (clb) bacteria are attracting attention. We aimed to clarify the interaction between clb Escherichia coli and normal colorectal epithelial cells in vivo and in vitro.

Materials And Methods: Five-week-old female Balb/c mice were divided in an untreated group, a group treated with clb E.

Various strategies have been proposed to achieve invisibility cloaking, but usually only one phenomenon is controlled by each device. Cloaking an object from two different waves, such as electromagnetic and acoustic waves, is a challenging problem, if not impossible, to be achieved using transformation theory and metamaterials, which are the major approaches in physics. Here, by developing topology optimization for controlling both electromagnetic and acoustic waves, we present a multidisciplinary attempt for designing biphysical cloaks with triple-wave cloaking capabilities, specifically for E- and H-polarized waves and acoustic wave.

The biofilm production of (PA) is central to establishing chronic infection in the airways in cystic fibrosis. Epithelial cells secrete an array of innate immune factors, including antimicrobial proteins and lipids, such as human beta defensin 2 (HBD2) and cholesteryl lineolate (CL), respectively, to combat colonization by pathogens. We have recently shown that HBD2 inhibits biofilm production by PA, possibly linked to interference with the transport of biofilm precursors.

Suspension culture is an essential large-scale cell culture technique for biopharmaceutical development and regenerative medicine. To transition from monolayer culture on the culture surface of a flask to suspension culture in a bioreactor, a pre-specified cell number must first be reached. During this period of preparation for suspension culture, static suspension culture in a flask is generally performed because the medium volume is not large enough to use a paddle to circulate the medium.

We succeeded in simultaneously cloaking and concentrating direct current in a conducting material through topology optimization based on a level-set method. To design structures that perform these functions simultaneously, optimal topology is explored for improving two objective functions that govern separately the cloaking and concentration of current. Our design scheme, i.

Artesunate (ART) is a clinically approved antimalarial drug and was revealed as a candidate of colorectal cancer chemopreventive agents in our drug screening system. Here, we aimed to understand the suppressive effects of ART on intestinal tumorigenesis. In vitro, ART reduced T-cell factor/lymphoid enhancer factor (TCF/LEF) promoter transcriptional activity.

It has been reported that activation of NF-E2 p45-related factor-2 (NRF2), a transcription factor, induces a variety of antioxidant enzymes, and plays an important role in preventing carcinogenesis. AHCC is a standardized extract of cultured mycelia and it has been demonstrated to improve cancer. However, the effects of AHCC on NRF2 have not been examined, and the effects on intestinal adenoma development are not yet fully understood.

The recombinant lectin rBC2LCN is a useful marker for discriminating the undifferentiated status of human induced or embryonic stem cells. Recently, rBC2LCN has also been used for detecting some cancers and niche cells. However, the generality of which types of cells are detected by rBC2LCN is unclear.
