Background & Aims: Diabetes is the most common cause of renal insufficiency throughout the world. The main cause of renal failure in diabetic patients is microvascular endothelial injuries that is secondary to atherosclerosis and ischemia. The efficacy of renal Doppler indices such as resistive index (RI) and pulsetile index (PI) for the evaluation of intrarenal arteries has been shown. This st...

The prognostic value of proliferation index (PI) and apoptotic index (AI), caspase-8, -9 and -10 expression have been investigated in primary Ewing's sarcoma family of tumours (ESFT). Proliferating cells, detected by immunohistochemistry for Ki-67, were identified in 91% (91/100) of tumours with a median PI of 14 (range 0-87). Apoptotic cells, identified using the TUNEL assay, were detected in ...

Introduction: Corrosion and scaling are important factors affecting drinking water quality, causing health and economic problems. This study aimed to investigate the indicators of corrosion and scaling in Rafsanjan drinking water. Materials and Methods: The present descriptive cross-sectional study was conducted in winter 2018 and spring 2019 in Rafsanjan. The 56 samples were randomly taken fr...

BACKGROUND Infarct heterogeneity has been shown to be independently associated with adverse outcomes in previous smaller studies. However, it is unknown whether infarct characterization is an independent predictor of all-cause mortality in patients with advanced ischemic cardiomyopathy, after adjusting for clinical risk factors, severity of ischemic mitral regurgitation, incomplete revasculariz...

Objective: To evaluate the value of Doppler velocimetry of umbilical and middle cerebral arteries and amniotic fluid volume in the surveillance of post term pregnancies. Design: Cross sectional study. Setting: Kasr El-Aini Hospital. Materials and Methods: Forty pregnant ladies with a gestational age of more than 41 weeks were compared to 40 pregnant ladies with gestational age ranging from 37 t...

Corrosion and scaling in drinking water sources can lead to economic and health damages. These processes produce by-products in distribution systems, reduce chemical water quality, and are the cause of health issues among consumers. The aim of this study was to evaluate the corrosion and scaling potential of water supply sources of Marivan villages, Iran. In total, 106 water samples were collec...

OBJECTIVE To establish reference range for uterine artery (UtA) Doppler pulsatility index (PI) using transvaginal ultrasound at 20-24w6d of gestation in a Brazilian population. MATERIAL AND METHODS A retrospective cross-sectional study in 847 low-risk pregnant women undergoing routine second trimester ultrasound examination was conducted from February 2012 through March 2015. The mean UtA PI ...
