New Insights Into the Three‐Dimensional Mechanics of the Flagellar Beat Cycle

Cytoskeleton, EarlyView.
ABSTRACT Advances in imaging at the molecular scale have provided greater detail concerning the three‐dimensional structure of the ciliary/flagellar axoneme. Additionally, it has recently been confirmed that electrostatic forces regulate the dynein‐tubulin interaction at the microtubule binding domain (MTBD) of dynein, and at the junction of the nexin ...

Female reproductive tract-on-a-chip for selecting sperm with ultra-low DNA fragmentation index

Microsystems & Nanoengineering
High levels of sperm DNA fragmentation index (DFI) represent a critical factor in male infertility, with detrimental effects on embryonic development and offspring well-being. However, selecting sperm with low DFI remains a tremendous challenge. Here, we

Impact of donor mare and stallion identity on the likelihood of pregnancy after transfer of in vitro produced embryos

Equine Veterinary Journal, EarlyView.
Abstract Background The success of in vitro embryo production (IVEP) is influenced by donor mare and stallion. Objectives To determine whether donor mare and stallion influence the pregnancy rate after transfer of in vitro produced (IVP) blastocysts and to identify factors influencing the likelihood of obtaining one or more pregnancies from a single ...

Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

Equine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.

Veterinarian and breeder perspectives surrounding ovum pick‐up and intracytoplasmic sperm injection in mares: A survey study

Equine Veterinary Journal, EarlyView.
Abstract Background There is an ethical debate about the application of ovum pick‐up (OPU) and intracytoplasmic sperm injection (ICSI) in mares. Objectives To survey the opinions of equine veterinarians and breeders of sport horses on the ethics of using OPU–ICSI in mares. Study Design Cross‐sectional descriptive study.
