Background In patients with abnormal uterine bleeding, transvaginal ultrasound (TVS) is the first-line diagnostic approach to exclude endometrial pathology. If a thickened endometrium suggests endometrial pathology, sonohysterography, office hysteroscopy or dilatation and curettage are the second-line tests preferred, depending on availability and on the suspected pathology, to exclude malignan...

tea is one of the most important medicinal plants which have a considerable effect on the treatment of cardiovascular disease and cancer. the drying process of tea leaves is carried out by hot air flow which consumes high level energy. the aim of the recent research was to investigate the procedure of high power ultrasound-assisted drying process of tea leaves. hybrid variety of chinese tea was...

Postoperative refractive outcome largely depends on the accuracy of calculating power of implanted IOL. Lens power calculation can be done by conventional ultrasound biometry and partial coherence laser interferometry (IOL Master). The aim was to compare the accuracy of IOL power calculations using conventional ultrasound biometry and partial coherence laser interferometry.40 eyes were included...

OBJECTIVES To determine if tumor vascularity as assessed by three-dimensional (3D) power Doppler ultrasound can be used to discriminate between benign and malignant ovarian tumors, if adding 3D power Doppler ultrasound to gray-scale imaging improves differentiation between benignity and malignancy, and if 3D power Doppler ultrasound adds more to gray-scale ultrasound than does two-dimensional (...

In this study, the effect of ultrasound on the foaming and emulsifying properties of wheat gluten as well as its electrophoretic and rheology properties were investigated. The foam capacity and foam stability of ultrasound treated wheat gluten proteins gradually increased as the treatment power increased, and were more pronounced at 100% power level. Excluding those of the raw wheat gluten, the...

The silk yarn containing Ag nanoparticles was prepared through the chemical reduction under ultrasound irradiation. In this system, ethylene glycol served as a reduction reagent and protecting silver nanoparticles from aggregation. The effect of some parameter, such as power of ultrasound irradiation and temperature in growth of the nanometric Ag were studied. Particle sizes and morphology of n...

urinary tract infections are common in children. the available gold standard method for diagnosis, tc-99m dimercaptosuccinic acid scan is expensive and exposes patients to considerable amount of radiation. this study was performed to compare and assess the efficacy of power doppler ultrasound versus tc-99m dmsa scan for diagnosis of acute pyelonephritis. a quasi experimental study was conducted...

The average acoustic power and intensity levels from diagnostic ultrasound machines at five major Hospitals in Benue State were measured using ultrasound power meter UPM-DT-10AV. The ultrasound machine at Christian Hospital Mkar, Immaculate Conception Hospital Makurdi, Federal Medical centre Makurdi, Myom Hospital Gboko and Lobi Specialist Hospital Makurdi were used for the research work. The u...

introduction: tea (camellia sinensis), is the most widely beverage after water across the world. the most important chemical composition in tea is phenolic compounds (catechins) that have antioxidant and anticarcinogenic properties and are benefited for cardiovascular disease. there are two major kinds of tea, black tea and green tea. green tea, is originated in china and dates back to several ...
