Advantages of cumulative pregnancy outcomes in freeze-all strategy in high responders - A case-control matching analysis of a large cohort.

Background/purpose: The freeze-all strategy in high responders is considered to be a safe and effective strategy for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment; however, the cumulative pregnancy outcomes have not been established.

Methods: A retrospective, single-center cohort study was conducted and 1311 high-responder patients (>20 oocytes retrieved and/or a serum estradiol level > 3000 pg/ml on the triggering day) were recruited from 2006 to 2015. The study group (n = 351) underwent the freeze-all strategy with subsequent thawed embryo transfer (ET), and the control group (n = 960) received fresh-cycle ET and subsequent thawed ET if needed.

A 45 nm Stacked CMOS Image Sensor Process Technology for Submicron Pixel.

A submicron pixel's light and dark performance were studied by experiment and simulation. An advanced node technology incorporated with a stacked CMOS image sensor (CIS) is promising in that it may enhance performance. In this work, we demonstrated a low dark current of 3.

Prenatal diagnosis of proximal femoral focal deficiency: a case report and literature review.

Objective: To present a rare case of fetal nonfamilial proximal femoral focal deficiency (PFFD) diagnosed as early as 21 weeks' gestation.

Case Report: A 32-year-old woman was referred to our hospital at 21 weeks' gestation. An ultrasound examination revealed isolated unilateral short femur (right femur = 27.
