Ultrasound prediction of birthweight and growth restriction in fetal gastroschisis.

Objective: Most ultrasound estimated fetal weight (EFW) formulas incorporate abdominal circumference, which may overstimate growth restriction in fetal gastroschisis. The aim of this study was to determine the optimal ultrasound formula for prediction of birthweight and fetal growth restriction (FGR) in gastroschisis.

Study Design: We conducted a retrospective cohort analysis of singleton fetuses with gastroschisis.

Invasive squamous cell carcinoma of the vagina in the setting of true hermaphroditism.

Background: Primary vaginal cancer constitutes less than 2% of all malignancies of the female genital tract and is even rarer in true hermaphrodites. A unique case report of the occurrence of both of these developments in the same patient is presented.

Case: A 31-year-old 46,XX hermaphrodite presented with a history of vague abdominal symptoms and weight loss.

Differential effects of Drosophila mastermind on asymmetric cell fate specification and neuroblast formation.

During neurogenesis in the ventral nerve cord of the Drosophila embryo, Notch signaling participates in the pathway that mediates asymmetric fate specification to daughters of secondary neuronal precursor cells. In the NB4-2 --> GMC-1 --> RP2/sib lineage, a well-studied neuronal lineage in the ventral nerve cord, Notch signaling specifies sib fate to one of the daughter cells of GMC-1. Notch mediates this process via Mastermind (Mam).
