The Oocyte/Antral Follicle Count Index: Does Maximizing Oocyte Yield Translate into Better Assisted Reproductive Technology Outcomes?

Journal of Ultrasound in Medicine, EarlyView.
Objectives Whether aspiration of more oocytes than the antral follicle count (AFC) is beneficial for the current and future products of assisted reproductive technologies (ART) cycles. Methods Data of the first oocyte aspiration for intracytoplasmic sperm injection performed between 2018 and 2022 in attempt to conceive (ICSI, n = 399) or for planned ...

Parallel Analysis of Acidic and Basic Proteoforms in Cell Lysates via Native Cation and Anion Exchange Chromatography—Native Mass Spectrometry

PROTEOMICS, EarlyView.
ABSTRACT Comprehensive characterization of proteoforms in complex biological systems remains a significant challenge. While native ion‐exchange chromatography (IEC) hyphenated with native mass spectrometry (nMS) is a powerful tool for resolving proteoforms, three critical limitations persist: restricted volatile buffers causing nonlinear pH gradients ...

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...
