Gestational trophoblastic neoplasia (GTN) is a hemorrhagic malignancy with highly rapid potential metastasis via hematogenous spreading. Renal metastasis is of infrequent occurrence. Among previous case reports of renal metastasis in GTN, this is the youngest woman presenting a large renal lesion concurrent with pulmonary and brain metastases. Disease remission had been achieved by treatment wi...

The effects of sublingual nitroglycerin (GTN) on left ventricular wall motion (LVWM) were examined by angiographic assessment in eight patients with anginal chest pain. Five of seven patients having occlusive coronary artery disease showed segmental abnormalities in LVWM characterized by regional hypokinesis or akinesis at rest. These abnormalities were accentuated by tachycardia induced by atr...

Indications and outcomes of hysterectomy in women with gestational trophoblastic neoplasia (GTN) were reviewed at Chiang Mai University Hospital, Chiang Mai, Thailand. From January 1998 through December 2008, 18 women underwent simple transabdominal hysterectomy (TAH). Indications for TAH included suspicious lesions confined to the uterus (5), chemoresistant lesions confined to the uterus (7), ...

Intravenous nitroglycerin (GTN) has been used as an anti-ischemic agent for the therapy of unstable and post-infarction angina. Nitric oxide (NO) and S-nitrosothiols constitute the biologically active species formed via nitroglycerin bioactivation. Increased levels of reactive oxygen species can diminish the therapeutic action of organic nitrates by scavenging donated NO and oxidizing tissue th...

Gestational trophoblastic neoplasias (GTN) are rare tumours that constitute less than 1% of all gynecological malignancies. Invasive mole is a distinct subgroup of GTN, which if not diagnosed and treated early, can result in serious complications like uterine perforation and haemoperitoneum. We present a rare case of an invasive mole of the uterus, which developed following the evacuation of a ...

background: gestational trophoblastic neoplasia (gtn) is a curable disease thatinvolves the development of malignant tumor in the woman after a normal or molarpregnancy. the position of surgery in gtn is not properly specified and is changingdue to new chemotherapy protocols. however, the role of surgery is highlighted inchemotherapy-resistant gtn. other indications of surgery in trophoblastic ...

Based on meso-damage mechanics and finite element analysis, the aim of this paper is to describe the feasibility of the Gurson-Tvergaard-Needleman (GTN) constitutive model in describing the tensile behavior of corroded reinforcing bars. The orthogonal test results showed that different fracture pattern and the related damage evolution process can be simulated by choosing different material para...

Introduction: Gestational trophoblastic neoplasia (GTN) is a group of interrelated lesions that results from abnormal proliferation placental cells. Early diagnosis and treatment GTN in successful outcomes with fertility preservation.This study was intended to stratify cases using WHO scoring system, diagnose manage as per protocol identify complications GTN.
 Methodology: This single cent...

In this paper, the initial and maximum load was studied using Finite Element Modeling (FEM) analysis during impact testing (CVN) of pipeline X70 steel. The Gurson-Tvergaard-Needleman (GTN) constitutive model has been used to simulate growth voids deformation steel at different temperatures. FEM simulations results study sensitivity with GTN parameters values proposed variation Finally, applied ...
