Imaging Findings of an Intraluminal Duodenal Diverticulum Associated with Adult Duodeno-Duodenal Intussusception and Recurrent Pancreatitis: A Case Report.

Intraluminal duodenal diverticulum (IDD) is a rare congenital abnormality, consisting of a sac-like mucosal lesion in the duodenum. Cases of IDD can present with gastrointestinal bleeding, duodenal obstruction, or pancreatitis. Here, we report a rare case of a 25-year-old female presenting with IDD complicated by duodeno-duodenal intussusception and recurrent pancreatitis.

Electrochemical Properties of Sn/C Nanoparticles Fabricated by Pulse Wire Evaporation for Lithium Secondary Batteries.

In this work, bare Sn and carbon-coated Sn nanoparticles were prepared by a pulsed wire evaporation process. The effect of binder and pressing ratio on electrochemical properties of Sn/C composite electrodes was investigated to enhance the structural stability of Sn anode. The electrode containing the polyamide-imide (PAI) binder with high tensile strength (52 MPa) exhibited higher coulombic efficiency and better cycle performance compared to the electrode with the conventional polyvinylidene fluoride (PVdF) binder.

Electrochemical Properties of Silicon-Polyacrylonitrile (PAN) Composite Anodes for Flexible Batteries.

Polyacrylonitrile (PAN)/Si composite fibers (electrodes) with flexibility were fabricated using an elec-trospinning method and then Si-embedded carbon (Si/C) fibers were prepared by carbonizing the composite fibers at 800, 900, and 1000°C. Si particles were distributed in the interior and exterior of entangled PAN fibers. After carbonization, the structure of electrodes was preserved but the diameter of fibers was decreased owing to the release of component elements constituting PAN such as nitrogen and oxygen.

The Efficacy of Cone-Beam CT-Based Liver Perfusion Mapping to Predict Initial Response of Hepatocellular Carcinoma to Transarterial Chemoembolization.

Purpose: To evaluate efficacy of cone-beam CT-based liver perfusion mapping obtained immediately following conventional transarterial chemoembolization of hepatocellular carcinoma (HCC) for assessing tumor vascularity, technical success of chemoembolization, and treatment response.

Materials And Methods: From July 2015 to June 2016, 35 patients with 57 HCCs who underwent cone-beam CT with post-processing software via conventional transarterial chemoembolization for HCC and follow-up examination were included. Three reviewers evaluated technical success on angiography, unenhanced cone-beam CT, contrast-enhanced cone-beam CT, and cone-beam CT-based liver perfusion mapping after transarterial chemoembolization per tumor and per patient.

MCP-1 and MIP-3α Secreted from Necrotic Cell-Treated Glioblastoma Cells Promote Migration/Infiltration of Microglia.

Background/aims: Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults. The defining characteristics of GBM are diffuse infiltration of tumor cells into normal brain parenchyma, rapid growth, a high degree of infiltration of microglia and macrophages, and the presence of necrosis. Microglia/macrophages are frequently found in gliomas and they extensively infiltrate GBM tissue, up to 30% of total tumor mass.

Effect of Ball Milling on Electrochemical Properties of Sulfur/Polyacrylonitrile (SPAN) Cathode in Li/S Battery.

Ball-milling process was applied to increase sulfur content in sulfur/polyacrylonitrile (SPAN) composites and improve electrochemical properties of Li/S batteries. In contrast to as-received PAN, pre-heated PAN was pulverized by the ball-milling, resulting in the continuous size reduction with increasing the milling time. Sulfur contents in SPAN composites synthesized with a pre-heated and milled PAN were increased with prolonging the milling time and the maximum content reached 44.

Effect of glucose level on chemical hypoxia- and hydrogen peroxide-induced chemokine expression in human glioblastoma cell lines.

Glioblastoma multiforme (GBM) is the most common primary intracranial tumor in adults and has poor prognosis. The GBM-specific tumor microenvironment (TME) plays a crucial role in tumor progression, immune escape, local invasion, and metastasis of GBM. Here, we demonstrate that hypoxia, reactive oxygen species (ROS), and differential concentration of glucose influence the expression of cytokines and chemokines, such as IL-6, IL-8, and IP-10, in human glial cell lines.

A Case of Primary Breast Diffuse Large B-Cell Lymphoma Treated with Chemotherapy Followed by Elective Field Radiation Therapy: A Brief Treatment Pattern Review from a Radiation Oncologist's Point of View.

We here report a case of primary breast lymphoma (PBL). A 44-year-old woman presented with a painless mass in the right breast. Fine needle aspiration cytology and excisional biopsy were performed.

Atypical hydroa vacciniforme-like epstein-barr virus associated T/NK-cell lymphoproliferative disorder.

Epstein-Barr virus (EBV)-associated T-cell/natural killer (NK)-cell lymphoproliferative disorders (EBV-T/NK-LPDs) accompany severe chronic active EBV infection (CAEBV) or comprise the CAEBV disease entity. The CAEBV disease entity has the common feature of lymphoproliferation of T or NK cells (primarily), and B cells (rarely), with chronic activation of EBV infection. The disease is rare and seems to be more prevalent in East Asian countries.

Treatment outcomes in patients with signet ring cell carcinoma of the colorectum.

Background: The aim of this study was to evaluate the clinicopathologic features and prognosis of signet ring cell (SRC) carcinoma and compare them with those of mucinous and poorly differentiated adenocarcinomas of the colorectum.

Methods: The clinicopathologic data of 35 patients with primary SRC carcinoma were reviewed and compared with the data from 294 patients with mucinous and 252 patients with poorly differentiated adenocarcinoma.

Results: Eighty percent of the SRC patients presented with more advanced disease (stages III and IV), whereas 55.
