Recently, there have been several major technical advances in the sonographic diagnosis of ovarian cancer in its early stages. These include improved assessment of tumor morphology with transvaginal sonography (TVS), and detection and characterization of tumor neovascularity with transvaginal color Doppler sonography (TV-CDS) and contrast-enhanced transvaginal sonography (CE-TVS). This paper wi...

The first hours of Drosophila embryogenesis rely exclusively on maternal information stored within the egg during oogenesis. The formation of the egg chamber is thus a crucial step for the development of the future adult. It has emerged that many key developmental decisions are made during the very first stages of oogenesis. We performed a clonal genetic screen on the left arm of chromosome 2 f...

OBJECTIVE The purpose of this study was to compare the outcomes of pregnancy after transabdominal cerclage versus after transvaginal cerclage in patients with a failed transvaginal cerclage during a previous pregnancy. STUDY DESIGN MEDLINE and EMBASE were searched in English. We included studies that reported perinatal and/or maternal outcomes in women who had a transabdominal cerclage or a t...

district of jiroft is situated in south-east of iran which is one of the malarious regions. anopheles stephensi is considered as one of the main malaria vector in this region. ecology of this species was studied in the area to understand its vector behavior for implementation of effective vector control measures. different methods like total catch, pit shelter, night bite collection on human an...

 ABSTRACT Background: To compare pregnancy outcomes in women at risk for cervical incompetence after elective versus ultrasound- indicated cerclage. Methods: In a prospective randomized tlial, singleton pregnancies with at least one previous spontaneous midtrimester loss or early preterm delivery (between 15 and 32 weeks' gestation) who met clinical crite1ia for the diagnosis of cervical incomp...

results totally, 101women were evaluated during the study. endometriosis was present at laparoscopy in 58 patients. mean age and the duration of infertility were calculated 30.78 ± 4.79 and 4.2 ± 2.91 years respectively. frequencies of each sonographic finding were as follow: echogenic points (%31.68), ovarian endometrioma (%30.69), blurred ovary margin (%7.92), fixation of ovaries (%15.9), dev...

background: ovarian functional cyst is one of the most common pelvic mass in reproductive age which mostly resolves spontaneously. sonography is a valuable tool for diagnosis of benign cyst with high accuracy. the objective of this cross sectional study was to evaluate the accuracy of transvaginal sonography in detecting type of ovarian cyst and compare the results wieh cytological results. mat...

The objectives were to evaluate the effects of sire and content of fresh or ionised egg yolk in extenders on sperm motility and share of live and dead sperm in collected ejaculate, in thawed artificial insemination (AI) doses, and during thermodynamic testing compared to extenders not containing egg yolk. Ejaculates were collected once a week from 4 Holstein bulls. Each of the 20 ejaculate samp...

Mercury contamination of wildlife populations has been documented widely in recent years as biomonitoring has become an important tool for assessing environmental contamination. Avian eggs provide an ideal assay material for Hg biomonitoring, particularly when the collection of eggs is simplified by using cavity-nesting species that nest in easily monitored nest boxes. However, studies are need...
