Twin to twin tranfusion syndrome (TTTS) is a rare condition that affects the identical pregnancy or other multiples. TTTS occurs when there an imbalance in blood flow between fetuses who share one placenta. This can cause fetus be dominant among called discordant twins. The of twins still unclear. But causes Twin-to-Twin Tranfusion Syndrome. incidence pregnancies around 15-29% total pregnancies...

Introduction The advent of transrectal ultrasonography has dramatically improved the ability of veterinarians to accurately diagnose and manage twin pregnancies in mares. As such the incidence of abortion due to twin pregnancy in mares has declined over the past 10 to 20 years [1]. In spite of the improved accuracy of detection and management of twin pregnancies in the mare associated with tran...

Methods A 31-year-old primigravid woman presented with a twin pregnancy at 14 weeks of gestation for evaluation of structural abnormalities in one co-twin. The marriage was non consanguineous. There was not history of genetic disorders or structural anomalies noted in the both parents. This was her first pregnancy and it was achieved by in vitro fertilization (ivf) and embryo transfer. One embr...

Dear Editor, The percentage of multiple births has increased over the past 3 decades, primarily as a result of advanced maternal age, the greater use and success of assisted reproductive technologies. The incidence of foetal malformations is higher in multifoetal pregnancies compared to singletons.1 In dizygotic (DZ) twins, there is essentially more than twice the risk per pregnancy (independen...

Physiological status and litter size affect ewes' hematological parameters, which serve as health indicators. These parameters reflect changes in an animal's physiological condition. Therefore, this study examined the profiles of Awassi ewes with single twin pregnancies during pregnancy postpartum. A total 232 sexually mature healthy (123 109 pregnancies) between ages 3 4 years were included cu...

The objective of this study was to determine the association between intracellular free AA (FAA) profiles in skeletal muscle with muscle growth in twin and singleton fetuses in late pregnancy and at weaning, under an ad libitum feeding regime of the dam. Plasma from singleton- (n = 9) and twin-bearing (n = 10) ewes at d 140 of pregnancy and FAA in the semitendinosus muscle (STM) from the corres...
