Altered Umbilical Cord Blood Nutrient Levels, Placental Cell Turnover and Transporter Expression in Human Term Pregnancies Conceived by Intracytoplasmic Sperm Injection (ICSI).

Assisted reproductive technologies (ART) may increase risk for abnormal placental development, preterm delivery and low birthweight. We investigated placental morphology, transporter expression and paired maternal/umbilical fasting blood nutrient levels in human term pregnancies conceived naturally ( = 10) or by intracytoplasmic sperm injection (ICSI; = 11). Maternal and umbilical vein blood from singleton term (>37 weeks) C-section pregnancies were assessed for levels of free amino acids, glucose, free fatty acids (FFA), cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), very low-density lipoprotein (VLDL) and triglycerides.

Virtual three-dimensional placentoscopy: a new approach to assess residual anastomoses following laser photocoagulation in twin-to-twin transfusion syndrome.

Twin-to-twin transfusion syndrome (TTTS) complicates 10% of monochorionic twin pregnancies and it is consequence of an unbalanced exchange blood through the vascular anastomoses at placental surface. If not treated, mortality rates in TTTS may be as high as 80-100%. Laser photocoagulation of the placental anastomoses is the first treatment option; however, in some situations, the damage of the placenta in the postpartum may become difficult the residual anastomoses identification.

Turner syndrome patients' ultrasound profile.

Objective: Evaluate the uterus and ovary by ultrasonography, considering the genotype, pubertal development and hormonal levels.

Materials And Methods: Cross-sectional study of 53 (7-53 years old) patients with Turner syndrome considering pubertal development by Tanner stage, puberty induced or not and the ultrasound examination.

Results: The patients were 10 prepubertal and 43 with pubertal signs.
