Cancer is considered as a challenging deathly disease and discovering or synthesis of new cytotoxic agents is a worldwide attempt. In this study, a group of recently synthesized chalcones, with the structure of 1,3-diarylprop-2-en-1-one having differesnt COX-1 and/or COX-2 selectivities, have been examined on human hepatocarcinoma (HepG2), lung carcinoma (A549), and breast adenocarcinoma (MCF-7...

BACKGROUND Although pulmonary hypertension due to left heart disease (LHD-PH) accounts for the largest proportion of pulmonary hypertension, few reports on the epidemiological analysis of LHD-PH exist. Recently, pulmonary arterial capacitance (PAC) has attracted attention as a possible factor of right ventricular afterload along with pulmonary vascular resistance. We therefore investigated the ...

BACKGROUND The aim of this study is to evaluate the prognostic factors of overall survival (OS) after haematopoietic stem cell transplant (HSCT) in acute lymphoblastic leukaemia (ALL) patients using accelerated failure time (AFT), Cox proportional hazard (PH), and Cox time-varying coefficient models. METHODS 206 patients were enrolled after HSCH in Shariati Hospital between 1993 and 2007. The...

BACKGROUND/AIMS A variety of risk factors for chronic kidney disease (CKD), including the metabolic syndrome, were recently reported. It has been suggested that a low urine pH is another characteristic of the metabolic syndrome. However, the relationship between urine pH and CKD remains to be elucidated. METHODS A cohort study was performed on 1,811 subjects who underwent a health check-up, a...

Over the last few decades, machine learning and data mining have been increasingly used for clinical prediction in ICUs. However, there is still a huge gap in making full use of the time-series data generated from ICUs. Aiming at filling this gap, we propose a novel approach entitled Time Slicing Cox regression (TS-Cox), which extends the classical Cox regression into a classification method on...

Background: Currently, cutaneous leishmaniasis (CL) as a parasitic disease is treated with Glucantime and Pentostam in most of the endemic countries. This study aimed to identify factors affecting the glucantime therapy duration rate in patients with CL using a survival analysis model. Methods: This retrospective descriptive-analytic study was conducted on 1017 CL patients that were referred t...
