Results: The mean values of peak systolic velocity, pulsatility index (PI) and resistive index (RI) of capsular artery (CA) and intratesticular artery (ITA) decreased significantly after LV and MV, whereas no significant change was observed in end-diastolic velocity. Comparing between two groups, the PI and RI values of left CA and ITA on 3rd month and of ITA on 6 month postoperatively in MV gr...

25 Although color Doppler ultrasonography has been used to evaluate testicular blood flow in 26 many species, very little has been done in goat. Eight male Shiba goats were exposed to a 27 single intramuscular injection of either gonadotropin-releasing hormone (GnRH group; 28 1μg/kg BW) or human chorionic gonadotropin (hCG group; 25 IU/kg BW). Plasma 29 testosterone (T), estradiol (E2), and inh...

In this work, TiO2 nanostructures were grown on titanium thin films by electrochemical anodizing method. The bipolar resistive switching effect has been observed in Pt/TiO2/Ti device. Resistive switching characteristics indicated the TiO2 nanotubes are one of the potential materials for nonvolatile memory applications.  Increasing anodizing duration will increase nanotube lengths which itself c...

Dural arteriovenous fistulas (DAVF) are frequent causes of pulsatile tinnitus. Color Doppler sonography may play a useful, complementary role to CTA/MRA and digital subtraction angiography (DSA) in the assessment of these anomalies’ characteristics, such as an ipsilateral increased flow volume and a low resistive index. In this article, we report a case of DAVF first detected with Color Doppler...
