Insulin-like peptide 3 (INSL3), a major product of testicular Leydig cells, is also expressed by the ovary, but its functional role remains poorly understood. Here, we quantified expression of INSL3 and its receptor RXFP2 in theca interna cell (TIC)...

Bone morphogenetic proteins (BMPs) are firmly implicated as intraovarian regulators of follicle development and steroidogenesis. Here we report a microarray analysis showing that treatment of cultured bovine theca cells (TC) with BMP6 significantly (...

Neohormones as biomarkers of reproductive health (2013)
Journal Article
Anand-Ivell, R., Dai, Y., & Ivell, R. (2013). Neohormones as biomarkers of reproductive health. Fertility and Sterility, 99(4), https://doi.org/10.1016/j.fertnstert.2012.12.023

Neohormone systems are defined as evolutionarily new endocrine or paracrine adaptations that supplement basic physiologic functions and define mammalian success. The relaxin family of peptide hormones are typical neohormones. Because they define the... Read More about Neohormones as biomarkers of reproductive health.

Brief maternal exposure of rats to the xenobiotics dibutyl phthalate or diethylstilbestrol alters adult-type Leydig cell development in male offspring (2013)
Journal Article
Ivell, R., Heng, K., Nicholson, H., & Anand-Ivell, R. (2013). Brief maternal exposure of rats to the xenobiotics dibutyl phthalate or diethylstilbestrol alters adult-type Leydig cell development in male offspring. Asian Journal of Andrology, 15(2), https://doi.org/10.1038/aja.2012.138

Maternal exposure to estrogenic xenobiotics or phthalates has been implicated in the distortion of early male reproductive development, referred to in humans as the testicular dysgenesis syndrome. It is not known, however, whether such early gestatio...

BRIEF COMMUNICATION: Mastitis pathogens isolated from dairy cattle that were managed on conventionally or organically maintained matched farmlets. Proceedings New Zealand Society of Animal Production, 73, 183-185

Mastitis is a common disease of dairy cattle causing significant economic loss. Several researchers have compared the incidence of mastitis in organically and conventionally managed dairy farms, with varying results. The majority of researchers found...

An evaluation of the changes in distance from the external sole surface to the distal phalanx in heifers in their first lactation (2012)
Journal Article

Veterinary Journal, 193(3), 639-643. https://doi.org/10.1016/j.tvjl.2012.06.045

Thin soles are a significant cause of lameness in dairy cattle but in most cases the diagnosis is based on subjective assessment. Ultrasonography has been used to more directly estimate sole thickness, but mostly on a one-off basis or over a short pe...
