Objectives: To study the uterine artery resistance and pulsation indices during the mid luteal phase in patients with history of unexplained recurrent pregnancy loss and the effects of the nitric oxide donor isosorbid mononitrite on these indices. Study Design: A cross-section, controlled observational study. Setting: Benha University Hospital, Egypt. July 2009 to July 2010. Subjects and Method...

OBJECTIVES To evaluate placental volume and vascular indices in pregnancies with severe fetal growth restriction and determine their correlations to normal reference ranges and Doppler velocimetry results of uterine and umbilical arteries. METHODS Twenty-seven fetuses with estimated weights below the 3rd percentile for gestational age were evaluated. Placental volume and vascular indices, inc...

Cloud contamination is one of the severest problems for the time-series analysis of optical remote sensing data such as vegetation phenology detection. Sub-pixel clouds are especially difficult to identify and remove. It is important for accuracy improvement in various terrestrial remote sensing applications to clarify the influence of these residual clouds on spectral vegetation indices. This ...

BACKGROUND The aim of this study was to determine the effect of Ramadan fasting on fetal growth and Doppler in-dices of pregnancy. METHODS Fifty two healthy pregnant women of second or third trimester, 25 in fasting group and 27 in non fasting group were included. Growth parameters including biparietal diameter (BPD), femoral length (FL), abdominal circumference (AC), estimated fetal weight, ...

UNLABELLED Doppler ultrasound is a non-invasive method for evaluating vascularization and is widely used in clinical practice. Gestational trophoblastic neoplasia includes a group of highly vascularized malignancies derived from placental cells. This review summarizes data found in the literature regarding the applications of Doppler ultrasound in managing patients with gestational trophoblasti...

BACKGROUND Whether salpingectomy affects ovarian function is controversial. In this study, ovarian function was assessed by antral follicle count, ovarian volume and ovarian stromal blood flow measured by three-dimensional (3D) power Doppler ultrasonography. The objectives of the study were to compare the ovarian function of the operated side with the non-operated side after unilateral salpinge...

PURPOSE To evaluate normal blood flow velocity and Doppler indices of the ophthalmic arteries from birth to hospital discharge of inborn infants at birth weights between 500 and 1500 g and gestational age <or=32 weeks. METHODS A longitudinal prospective study with Doppler ultrasound was conducted in both eyes at 24 hours, 7 and 28 days, and hospital discharge for systolic and diastolic veloci...

Saline lakes can increase the soil and water salinity of the coastal areas. The main aim of this study is to distinguish the characteristics of the spectral reflectance of saline soil, analyze the statistical relationship between soil EC and characteristics of the spectral reflectance of saline soil, and to map soil salinity east of the Maharloo Lake. The correlation between field measurements ...
