BACKGROUND Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are a heterogeneous group of rare tumors. Many issues in terms of epidemiologic features, pathogenesis, and treatment of GEP-NENs are still under discussion. Our study aimed to analyze the clinicopathologic characteristics and prognosis of Chinese patients with GEP-NENs. METHODS Complete clinicopathologic data and survival ...
BACKGROUND Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are the most common type of neuroendocrine tumors, accounting for more than half of neuroendocrine neoplasms (NENs). We performed a retrospective study in our center to investigate the clinicopathological features, risk factors of metastasis, and prognosis of GEP-NENs in a Chinese population. METHODS Four hundred forty pati...
BACKGROUND There is rising incidence of gastroenteropancreatic neuroendocrine tumours (GEP- NETs) in many parts of the world, but epidemiological data from Asian populations is rare. METHODS We conducted a retrospective study in a tertiary medical centre in Hong Kong, using updated diagnostic criteria. The presentation, clinical features, and disease outcome were reviewed for all patients wit...
هدف از تحقیق حاضر مدل‌سازی توزیع آرسنیک در دشت چهاردولی با استفاده از زمین‌آمار، منطق فازی و برنامه‌ریزی بیان ژنتیک (GEP) می‌باشد. بدین منظور گروه زمین‌شناسی دانشگاه تبریز در مهر 1393 اقدام به نمونه‌برداری از منابع آب زیرزمینی این دشت نمود. که نتایج حاصل حاکی از غلظت‌های بالای آرسنیک در منطقه می‌باشد. پارامترهای هیدروشیمیایی شامل آرسنیک و سیلیس، پتاسیم و سدیم که همبستگی بالایی با مقادیر آرسنیک ...
The aim of this paper is to introduce and study a dual problem associated to a generalized equilibrium problem (GEP). We show that the solutions of (GEP) and its dual are strictly related to the saddle points of an associated Lagrangian function, and, under some suitable conditions, to the solutions of a family of parametric optimization problems and their dual problems. Our results allow us to...
PURPOSE Advances in personalized medicine have produced novel tests and treatment options for women with breast cancer. Relatively little is known about the process by which such tests are adopted into oncology practice. The objectives of the present study were to understand the experiences of medical oncologists with multigene expression profile (gep) tests, including their adoption into pract...
Purpose: The role of growth factors in ovarian cancer development and progression is complex and multifactorial. We hypothesized that new growth factors may be identified through the molecular analysis of ovarian tumors as they exist in their native environment. Experimental Design: RNA extracted from microdissected serous low malignant potential (LMP) and invasive ovarian tumors was used to co...
PURPOSE Multiple myeloma is an incurable malignant plasma cell disease characterized by survival ranging from several months to more than 15 years. Assessment of risk and underlying molecular heterogeneity can be excellently done by gene expression profiling (GEP), but its way into clinical routine is hampered by the lack of an appropriate reporting tool and the integration with other prognosti...
[1] Northern peatlands are likely to be important in future carbon cycle-climate feedbacks due to their large carbon pools and vulnerability to hydrological change. Use of non-peatland-specific models could lead to bias in modeling studies of peatland-rich regions. Here, seven ecosystem models were used to simulate CO2 fluxes at three wetland sites in Canada and the northern United States, incl...
PURPOSE As a result of various independently proposed nomenclatures and classifications, there is confusion in the diagnosis and prediction of biological behavior of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). A comprehensive nationwide study is needed in order to understand the biological characteristics of GEP-NETs in Korea. MATERIALS AND METHODS We collected 4,951 pathology re...
