Enlightening the Immune Mechanism of the Abscopal Effect in a Murine HCC Model and Overcoming the Late Resistance With Anti-PD-L1.

Purpose: The establishment of a preclinical model of the abscopal effect on hepatocellular carcinoma (HCC) and evaluation of whether the hypofractionated radiation therapy (RT) multitumor Hepa1-6 mouse HCC model could be used to suppress nonradiated tumor mass was performed in this study.

Methods And Materials: Hepa1-6 mouse liver cancer cell lines were used to form tumors. Immunogenicity was analyzed using ELISpot and immune cell labeled antibody.

Setup uncertainties for inter-fractional head and neck cancer in radiotherapy.

Purpose: The aim of this study is to determine the inter-fractional motion of cervical spine in radiotherapy (RT).

Materials And Methods: Eleven localized head and neck cancer patients who were treated from April 2014 to September 2015 were evaluated. Every patient underwent 3 times of computed tomography (CT) simulation with equivalent setting.

Comparative analysis of radiation dose and image quality between thyroid shielding and unshielding during CT examination of the neck.

Objective: The purpose of this study is to evaluate the feasibility of thyroid shielding by measuring radiation dose, CT attenuation, and noise of superficial neck structures during CT examination.

Subjects And Methods: We divided 84 patients without abnormalities seen on CT into two groups depending on whether shielding with a cotton spacer was applied over the thyroid. On CT images, we measured the CT attenuation and noises in the strap and sternocleidomastoid (SCM) muscles.

Radiography, Bone Scan, and F-18 FDG PET/CT Imaging Findings in a Patient with Paget's Disease.

Background: A 52-year-old female patient sought evaluation at our hospital for an incidental abnormal finding on an abdominal radiograph.

Methods: The initial radiograph showed irregular sclerotic changes involving the right pelvic bone. At the same time, bone scintigraphy showed intense hot uptake in the right iliac and pubic bones.

Sonography of biopsy-proven Langerhans cell histiocytosis in lymph nodes of the neck.

Objective: The purpose of this series is to describe the sonographic findings of lymph nodes of the neck involved by Langerhans cell histiocytosis (LCH).

Methods: We reviewed and interpreted available images of lymph nodes in patients with cervical lymphadenopathies involved by LCH for the past decade. In all patients, each abnormal lymph node was pathologically confirmed by the use of a sonographically guided core needle biopsy or an incisional biopsy.

Dielectric properties of Ni-coated BaTiO/sub 3-/PMMA composite.

Dielectric properties of Ni-coated BaTiO(3)-PMMA (polymethyl methacrylate) composite were studied from an embedded capacitor application viewpoint. Volume loading of up to 50% was attempted, and the results were compared with uncoated BaTiO(3)-PMMA composite. Ni-coating on BaTiO(3) powder was found to greatly improve the dielectric properties of the composite, especially the dielectric constant value.
