GTn Repeat Microsatellite Instability in Uterine Fibroids [PDF]
Frontiers in Genetics, 2019 Background: Type I collagen is a triple helix structure with two α1 and one α2 chains. Coordinated biosynthesis of α1 and α2 subunits is very important for tissue morphogenesis, growth, and repair. In contrast, abnormal deposition in response to proinflammatory cytokines is associated with organ dysfunction.

Glyceryl trinitrate for prevention of post-ERCP pancreatitis and improve the rate of cannulation: a meta-analysis of prospective, randomized, controlled trials. [PDF]
PLoS ONE, 2013 BACKGROUND: Acute pancreatitis is the most common complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP). Several clinical trials used glyceryl trinitrate (GTN) to prevent the incidence of post-ERCP pancreatitis (

A profile of Gestational Trophoblastic Neoplasia in a tertiary hospital in Surabaya, Indonesia
Majalah Obstetri dan Ginekologi, 2023 HIGHLIGHTS • This study aimed to identify the characteristics of Gestational Trophoblastic Neoplasia (GTN). • GTN is chemosensitive, but without appropriate therapy and follow-up, GTN will develop into complications and fatalities.

Application of an Advanced GTN Model [PDF]
Volume 1: Advanced Computational Mechanics; Advanced Simulation-Based Engineering Sciences; Virtual and Augmented Reality; Applied Solid Mechanics and Material Processing; Dynamical Systems and Control, 2012 The present contribution consists of implementing an advanced GTN damage model as a “User Material subroutine” in the Abaqus FE code. This damage model is based on specific nucleation and growth laws. This model is applied to the prediction of the damage evolution and the stress state in notched specimens made of dual phase steel.

Numerical Study on Ductile Failure Behaviours of Steel Structures under Quasi-Static Punch Loading
Journal of Marine Science and Engineering, 2023 A reliable finite element procedure to simulate shear-dominated ductile fractures in large-scale, thin-walled steel structures is still evolving primarily due to the challenges in determining the failure criterion of metal materials under complex stress ...

The Study of the Sensitivity of GTN Parameters
Procedia Structural Integrity, 2020 Abstract Gurson–Tvergaard–Needleman (GTN) model is a quite reliable tool that we can use to predict the failure of a component. Still, the determination of those parameters is not an easy task. It takes much time for computing, and sometimes we do find different sets of GTN parameters, with the same results after simulation. The purpose of this paper

An Analysis of the Tvergaard Parameters at Low Initial Stress Triaxiality for S235JR Steel
Polish Maritime Research, 2015 This paper discusses the influence of the Tvergaard parameters, qi, which are basic constants of the Gurson-Tvergaard-Needleman (GTN) material model, on the numerically simulated load-carrying capacity of tensile elements made of S235JR steel.

Glyceryl Trinitrate: History, Mystery, and Alcohol Intolerance
Molecules, 2021 Glyceryl trinitrate (GTN) is one of the earliest known treatments for angina with a fascinating history that bridges three centuries. However, despite its central role in the nitric oxide (NO) story as a NO-donating compound, establishing the precise ...
