Giant Cell Tumor of Soft Tissue: a Case with Atypical US and MRI Findings
We report the case of a giant cell tumor with diffuse interstitial hemorrhaging and unusually prominent cystic components in the soft tissue of the thigh which has not been reported previously. Magnetic resonance image (MRI), showed signal intensity typical of a giant cell tumor. However, because of its conspicuous large well-circumscribed cystic components, the differential diagnoses, based on the image findings from an ultrasonography (US) and MRI, were complicated epidermoid cyst, cystic change of a neurogenic tumor, and a parasitic cyst
Ultrasound and Fluoroscopy-Guided Placement of Central Venous Ports via Internal Jugular Vein: Retrospective Analysis of 1254 Port Implantations at a Single Center
Granulocytic sarcoma presenting with necrotic cervical lymph nodes as an initial manifestation of childhood leukaemia: imaging features
We present two cases of granulocytic sarcoma of the cervical lymph nodes with central necrosis as an initial manifestation of childhood leukaemia, focusing on the imaging features. Recognition of the CT and MR imaging findings of granulocytic sarcoma involving the cervical lymph nodes assists the differential diagnosis of noninfective lymphadenopathy in children

Efficacy of Endobiliary Radiofrequency Ablation using a Novel Endoluminal Radiofrequency Ablation Catheter in a Swine Model
Strain-Gradient Effect in Gas Sensors Based on Three-Dimensional Hollow Molybdenum Disulfide Nanoflakes
A novel
three-dimensional transition metal dichalcogenide (TMD) structure
consisting of seamless hollow nanoflakes on two-dimensional basal
layers was synthesized by a one-step chemical vapor deposition method.
Here, we demonstrate that the as-grown nanoflakes are formed on an
organic promoter layer which served as a positive template and are
swollen at the grain boundaries by the bubbling effect. TMD nanosheets
with hollow nanoflakes are successfully applied as chemical sensors,
and it was found that their gas adsorption property is strongly related
to the internal strain gradient resulting from the variation in the
lattice parameter. This result is consistent with the theoretical
prediction in previous studies. Our chemical vapor deposition-based
approach is an efficient way to generate TMD-based nanostructures
over a large surface area for various practical applications such
as chemical sensors
More effective use of graphene in photocatalysis by conformal attachment of small sheets to TiO2 spheres
Bifidobacterium bifidum strains synergize with immune checkpoint inhibitors to reduce tumour burden in mice.
The gut microbiome can influence the development of tumours and the efficacy of cancer therapeutics1-5; however, the multi-omics characteristics of antitumour bacterial strains have not been fully elucidated. In this study, we integrated metagenomics, genomics and transcriptomics of bacteria, and analyses of mouse intestinal transcriptome and serum metabolome data to reveal an additional mechanism by which bacteria determine the efficacy of cancer therapeutics. In gut microbiome analyses of 96 samples from patients with non-small-cell lung cancer, Bifidobacterium bifidum was abundant in patients responsive to therapy. However, when we treated syngeneic mouse tumours with commercial strains of B. bifidum to establish relevance for potential therapeutic uses, only specific B. bifidum strains reduced tumour burden synergistically with PD-1 blockade or oxaliplatin treatment by eliciting an antitumour host immune response. In mice, these strains induced tuning of the immunological background by potentiating the production of interferon-γ, probably through the enhanced biosynthesis of immune-stimulating molecules and metabolites
