Embryonic development of the Mediterranean starfish Hacelia attenuata

Developmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Low-Level Human Epididymis Protein 4 in Seminal Plasma Is an Independent Risk Factor for Poor Semen Liquefaction: A Case Control Study. [PDF]

J Clin Lab Anal
Our work identifies a novel and significant association between low seminal levels of Human Epididymis Protein 4 (HE4) and the clinical condition of poor semen liquefaction, a common cause of male infertility. The findings are statistically robust, clinically relevant, and provide a foundational basis for future research into the mechanism by which HE4

A shining starlet: Nematostella vectensis as a model for developmental, regenerative, and comparative biology

Developmental Dynamics, EarlyView.
Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

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 ...

Fern sperm release

, 2016
Fern spores germinate into haploid fern gametophytes; small plants only a few millimeters in diameter. These gametophytes produce sperm by mitosis in small sacs called antheridia. When placed in water, the antheridium opens up, and the sperm are released.

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.
