Background: Arteriovenous fistula is an important method for hemodialysis and prediction of fistula function and failure rate and access is crucial. This study was performed to determine the association between Doppler ultrasonography findings with function and failure and access rate of fistula. Methods: In this observational comparative cross-sectional study, out of 108 patients requiring fi...
An 18 yr old female referred to us as hypertrophic obstructive cardiomyopathy with bicuspid aortic valve. On Initial history and examination patient also had primary amenorrhoea, differential cyanosis in lower limbs, differential clubbing, polydactyly, syndactyly, high arched foot, pectus carinatum and scoliosis. Oxygen saturation was 94% at room air and complete blood count was suggestive of p...
Objective
 Shear wave elastography (SWE) is a new
 ultrasonography technique that can non-invasively
 evaluate liver stiffness. The efficacy of SWE in adults
 has been demonstrated by numerous studies, but
 there are few studies pediatric groups. Since
 the stiffness values (LSV) vary according to the
 device and method used, standard reference
 have not ...
introduction emerging hypotheses suggest a causal role for prenatal androgen exposure in some cases of autism spectrum disorders (asd). the ratios of the lengths of the bones of the 2nd to the 4th digits (2d:4d) are purported to be markers for prenatal androgen exposure and to be established early in gestation. ratio of second and fourth digits (2d:4d) is usually used as a proxy for prenatal t...
We report an experimental study of the backscattering of a sound wave of frequency f by a surface vibrating harmonically at frequency F (F << f) and amplitude A in the regime where the Doppler effect overcomes bulk nonlinear effects. When the duration to of the analyzed time series of the scattered wave is small compared to the vibration period, the power spectrum of the backscattered wave is p...
In this paper, a scalable e-health architecture based on the Internet of Things (IoT) technology is proposed. In this suggested architecture, the clinic hardware can communicate with other clinics' hardware remotely with minimal or no human intervention, which is a key difference between the proposed architecture and the former ones. The idea of our architecture is to use the internet as a...
