introduction: distal radius fractures are a common traumatic injury, particularly in the elderly population. in the present study we examined the effectiveness of ultrasound guidance in the reduction of distal radius fractures in adult patients presenting to emergency department (ed). methods: in this prospective case control study, eligible patients were adults older than 18 years who presente...
background & aim: restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (bha) and butylated hydroxytoluene (bht) are being imposed because of their carcinogecity . experimental: in this investigation, optimization of phenolic extraction process from methanolic (80%) extract (v/v) of flomideschema parviflorum through response surface methodology by fulin cio-calt...
aim : to create an orthotopic hepatoma model with local metastasis monitored with ultrasound could be created as a platform for testing new treatments. background : hepatoma accounts for 25% of liver tumors in children with poor overall survival. intraabdominal metastasis are present in 35% of patients at time of diagnosis. we hypothesized that an orthotopic tumor model with local metastasis...
It is over several decades that ultrasound is used to enhance the transdermal drug delivery (phonphoresis). The mechanism of the enhancement is not fully understood and the ability of ultrasound on the enhancement for some drugs is unclear. The effect of continuous wave 870 KHz ultrasound at intensity of 1 W/cm 2 for 15 minutes on transdermal absorption of piroxicam from solution and gel formu...
در شیمی، مطالعه سـونوشیمی]28 (sonochemistry) [به درک اثـــرات امــواج صــوتی (sonic waves) و خواص موج بر سیستم های شیمیایی مربوط می شود. اثرات شیمیایی فراصوت (ultrasound) از اثر مستقیم با گونه های مولکولی بدست نمی آید. مطالعات نشان داده است که هیچ برهم کنش مستقیمی بین میدان صوتی و گونه های شیمیایی در سطح مولکولی برای سونوشیمی [29] یا سونولومینسانس [30] گزارش نشده است. در عوض سونوشیمی از حفره سا...
Inducing a Normal Phenotype in Breast Epithelial Cells Using a ThreeDimensional Basement Membrane Extract Culture System: A Study on the Reversion of Cancer
Abstract Background: The most common causes of abnormal uterine bleeding in women of reproductive age are uterine structural abnormalities. There are several modalities for the examination of abnormal uterine bleeding, including transvaginal ultrasound and hysteroscopy. In this study, we aimed to investigate the diagnostic accuracy of hysteroscopy versus transvaginal ultrasound in the diagnosis...
The ability to sense and respond to physical stimuli is an important key of the life. It was recognized that ultrasound as a physical stimulus could produce drastic changes in biological systems. High-intensity ultrasound is well known to be destructive to biological materials, but low-intensity ultrasound, on the other hand, has shown a range of biological effects with potential significance i...
This review presents the results of recent years on solving Palis problem finding necessary and sufficient conditions for embedding Morse–Smale cascades in topological flows. To date, has been solved by diffeomorphisms given manifolds dimension two. The result circle is a trivial exercise. In dimensions three higher new effects arise related to possibility wild embeddings closures invariant sad...
