BACKGROUND: Jeju Island is geographically and socioeconomically distinct from the mainland of South Korea. Thus, the presentation and management of non-melanocytic skin cancers (NMSC) of the head and neck may differ from those in other regions of the country. We compared the clinical characteristics and treatment modalities of NMSC on Jeju Island with the findings of similar regional studies. METHODS: Patient data, including age, sex, diagnosis, tumor site, treatment, and recurrence, were obtained from the medical and pathology records of patients diagnosed with NMSC between January 2010 and June 2015...

Background/Aims: Helicobacter pylori (Hp) infection is an important risk factor for gastric carcinogenesis. Although several studies have investigated the effect of Hp eradication on the development of metachronous neoplasm after endoscopic resection of the gastric dysplasia, the evidence is still insufficient to make a clear conclusion. The aims of this study was to evaluate the risk factors for the development of metachronous neoplasm after endoscopic resection of gastric dysplasia and to investigate the effect of Hp eradication...

Objective: To discuss the imaging findings and clinicopathological features of the intramural gastric metastasis (IGM) of esophageal squamous cell carcinoma. Methods: The imaging findings of 11 patients with IGM confirmed by surgical pathology were reviewed retrospectively, and compared with clinicopathological features. Of the 11 cases, eight underwent upper gastrointestinal radiography, ten underwent contrast enhanced computed tomography (CT) scans and one underwent plain CT scanning. Results: In all 11 cases, the primary cancer was located in the middle or lower thoracic esophagus, and nine of 11 had lymph nodes metastasis...

Objective: To explore the in vitro and in vivo effect of GP73 on the proliferation, invasion and metastasis in hepatocellular carcinoma. Methods: GP73 gene was knocked out using CRISPR/Cas9 gene editing system in H22 and HepG2 cells, and stable knock out strains were constructed. The knockout efficiency was measured by western blot. Colony formation assay was used to detect the effect of GP73 on long-term survival ability. Cells were then highly synchronized in G(1) phase upon treatment with cell synchronization reagents (mimosine), and the percentage of cells in G(2)/M phase at different time points was detected by flow cytometry...

Objective: As solitary fibrous tumor (SFT) and hemangiopericytoma (HPC) share the same molecular genetics features, the 2016 WHO classification of central nervous system (CNS) tumors had created the combined term SFT/HPC and assigns three grades. This study aims to investigate the clinicopathologic characteristics, diagnosis, differential diagnosis and prognosis of CNS SFT/HPC. Methods: Seventy-one cases of CNS SFT and HPC were retrospectively reclassified and studied. Histopathological, immunohistochemical and imaging features were analyzed...

Juxtapapillary capillary hemangioma (JCH) is a vascular hamartoma. Fluorescein fundus angiography aids in diagnosis. The vascular morphology of this tumor has not been documented with optical coherence tomography angiography (OCTA), a new, noninvasive diagnostic modality that provides high-resolution images of vascular pattern based on blood flow in the retina and choroid. Although mainly a clinical diagnosis, OCTA helps in studying the intrinsic vascularity of the tumor and helps in differentiating it from other vascular tumors...

OBJECTIVE: The histologic response to neoadjuvant chemoradiotherapy (CRT) has been intimately related to outcomes in locally advanced rectal cancer. However, reliable prognostic factors have yet to be established. SUBJECTS AND METHODS: The study group comprised 198 patients with locally advanced rectal cancer who received CRT. A modified classification based on the combination of ypStage and tumor regression grade (TRG) was developed. ypStage II with TRG 2 was classified as ypTRGstage IIA, and ypStage II with TRG 3 or 4 was classified as ypTRGstage IIB...

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are rare neoplasms accounting for less than 5% of all pancreatic malignancies. These tumors are characterized by clinical and prognostical heterogeneity and are predominantly diagnosed in a metastatic stage. Cytotoxic chemotherapy, along with alkylating agents and antimetabolites as well as molecular targeted agents (everolimus, sunitinib), is used in the treatment of advanced PNETs. After the approval of lanreotide for unresectable PNETs, an additional therapeutic option has become available; however, the best sequence of therapies and patient stratification to different treatments remains challenging...

We have designed a series of tacrine-based homo- and heterodimers that incorporate an antioxidant tether (selenoureido, chalcogenide) as new dual compounds: for the treatment of Alzheimer's disease and as antiproliferative agents. Symmetrical homodimers bearing a dichalcogenide or selenide-based tether, the best compounds in the series, were found to be strong and highly selective electric eel AChE inhibitors, with inhibition constants within the low nanomolar range. This high inhibitory activity was confirmed on recombinant human AChE for the most interesting derivatives...

The Maillard reaction is a nonenzymatic reaction between an amino acid and a reducing sugar that usually occurs upon heating. This reaction occurs routinely in cooking, generates numerous products, which are collectively referred to as Maillard reaction products (MRPs) contributing to aroma and color features. Advanced glycation end-products (AGEs) transformed from MRPs are participated in many types of inflammation reaction. In this study, various sugar-amino acid MRPs were prepared from three different amino acids (lysine, arginine, and glycine) and sugars (glucose, fructose, and galactose) for 1 h with heating at 121 °C...
