Efforts to better understand and prevent suicide have increasingly pointed to the prospective assessment of suicidal behaviors in clinical trials. These assessments are aided by instruments such as the Columbia-Suicide Severity Rating Scale (C-SSRS), which have sought to improve the conceptual uniformity and ease by which suicidal behaviors are classified. At the same time, assessment and classification of suicidal behaviors has been a longtime challenge in the field. To aide users of the C-SSRS, this manuscript illustrates the use of the C-SSRS in instances where classification complexities arise...

MEK inhibitor (selumetinib) is a potent, orally active inhibitor of MAPK/ERK pathway. It is important to develop an accurate and robust method indicative of RAS pathway activity to stratify potential patients who can benefit from selumetinib treatment in gastric cancer (GC). First, we surveyed the sensitivity to selumetinib in a panel of 22 GC cell lines and correlated with MEK signature to selumetinib sensitivity. Next, we analyzed MEK signature via nanostring assay in two Asian cohorts using clinical samples (n = 218) and then performed a correlative analysis with MEK signature status and KRAS genotype in GC...

The discovery of cell type-specific markers can provide insight into cellular function and the origins of cellular heterogeneity. With a recent push for the improved understanding of neuronal diversity, it is important to identify genes whose expression defines various subpopulations of cells. The retina serves as an excellent model for the study of central nervous system diversity, as it is composed of multiple major cell types. The study of each major class of cells has yielded genetic markers that facilitate the identification of these populations...

Studies on the pattern-based classification for invasive endocervical adenocarcinoma showed that tumors with nondestructive invasion (pattern-A) have a 0% rate of nodal metastases. Our understanding of pattern-A tumors and their distinction from in-situ adenocarcinoma requires further study. Thirteen sections diagnosed independently as pattern-A adenocarcinoma by three gynecologic pathologists, and 14 sections of benign endocervix were selected. Three additional pathologists (reviewers) evaluated a digital image from each section and classified it as pattern-A or benign based on architecture only...

INTRODUCTION: Gastric carcinoma is a leading cause of death worldwide with a five year survival of 10-15% even after curative resection. Trastuzumab has emerged as a potential targeted therapy in treatment of Her 2 positive gastric cancer. Her2 positivity ranges from 7-34% in studies across the world. There is a paucity of Indian studies hence a need for determination of Her2 expression in Indian population for better patient management. This study was carried out to determine the frequency of Her 2 expression in gastric carcinoma by immunohistochemistry (IHC) technique and to evaluate its association with histopathological parameters...

BACKGROUND: Ring finger protein 43 (RNF43) is a member of the transmembrane E3 ubiquitin ligase family that was originally found in stem cells and plays important roles in tumor formation and progression. Our previous study indicated that RNF43 might be a tumor suppressor protein in gastric cancer. Given its antagonistic relationship with leucine-rich repeat-containing G-protein-coupled receptor 5 (Lgr5), one of the gastric cancer stem cell markers, investigation of the potential role of RNF43 in gastric stem cancer cells is necessary...
