New Sites for the Use of Pulse-mode Ultrasound to Detect Pregnancy in Cattle
نویسنده
چکیده
New sites developed for improved cattle testing are described in this paper. Two separate trials were conducted on a total of 379 Friesian and Brahman cows. In the first test, conducted with an early version of the RENCO PREG-ALERT®(2) modified or cattle testing, the accuracy rate was 96.6% for non pregnant cows, and 90.4% for cows determined to be 5 weeks to 8 months pregnant by rectal palpation. An overall accuracy of 94.8% (both pregnant and non pregnant) was achieved with one test and 95.5% after necessary second retests.

Comparison the treatment effects between simultaneous dual frequency and single frequency irradiation of ultrasound in a murine model of breast adenocarcinoma
Introduction: Transient cavitations induced by low frequency irradiation of ultrasound can be used to treat tumors. Previous studies in in-vitro experiments have shown that induced cavitation by dual or multiple frequencies of ultrasound is greater than induced cavitation by single frequency irradiation. In this study, we compared and evaluated the treatment effects of dual frequency irradiatio...

ABSTRACTBackground : In order to quantify effects of ultrasound irradiation parameters under therapeutic condition, especially sonodynamic therapy, it is initially necessary to evaluate inertial cavitation activity in vitro conditions therefore, in this study, the effect of 1 MHz low level ultrasound based on °OH radicals generated by acoustic inertial cavitation in aqueous solution was monit...

Bovine viral diarrhea virus (BVDV) is a significant pathogen associated with gastrointestinal, respiratory, and reproductive diseases of cattle worldwide. It causes continuous economic losses to the cattle industry primarily due to decreased reproductive performance. The ability of virus to cross the placenta during early pregnancy can result in the birth of persistently infected (PI) calves. P...

Introduction: One of the challenges facing ovarian transplantation is overcoming the ischemia/ reperfusion injury. When blood supply to the implanted tissue is suboptimal (immediate post implant period), ultrasound therapy has been shown to increase mass transport. The aim of this study was to investigate the effect of ultrasound on heterotopic transplantation of mouse ovarian tissue. Methods...
متن کاملEvaluating the Effects of Dual Frequency Sonication Parameters on Acoustic Cavitation by Chemical Dosimeter Using Iodide
Background and Aims: Production of acoustic cavitation by sonication has been recently recommended as a targeted treatment. The experimental results from studies indicate that the activity of cavitation generated by bi- or multi-frequency ultrasound irradiation is higher than that caused by single frequency irradiation. In this study, effects dual (1 MHz and 40 kHz) and single frequency soni...
