Validation of grizzly bear hair hormone profiles as a tool to monitor population demographics

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We measured 16 steroid and thyroid hormone concentrations in grizzly bear hair to predict sex, age class, and reproductive status. Models were highly accurate when predicting sex and age class and showed promise for assessing reproductive status. Results illustrate the potential for hair hormone profiles as non‐invasive population monitoring tools ...

INDUCTION OF PSEUDOPREGNANCY IN THE GOLDEN HAMSTER [PDF]

Reproduction, 1968
In the hamster, unlike the rat in which pseudopregnancy is induced with ease, past attempts to induce pseudopregnancy by mechanical vaginal-cervical stimulation have been unsuccessful (Carlson & DeFeo, 1953; DeFeo, 1966.) Pseudopregnancy in this species is usually induced by mating an oestrous female with a vasectomized buck overnight. The wide use

The Absence of Collagen VI Reduces Systolic Function but Paradoxically Increases Ca2+ Release in the Rat Heart

Acta Physiologica, Volume 242, Issue 1, January 2026.
ABSTRACT Aim Collagen VI has recently been strongly linked to poor outcomes in heart failure through increased endotrophin, a collagen VI‐derived signaling molecule linked to fibrotic remodeling in cardiovascular disease. The mutation of collagen VI can result in Ullrich congenital muscular dystrophy and Bethlem myopathy, pointing to a critical ...

Specific effects on the reproductive function including fertility relevant for cumulative risk assessment of pesticide residues

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract According to the ‘EFSA‐SANTE Action Plan on Cumulative Risk Assessment for pesticides residues’, EFSA, with the support of a working group, undertook the identification of specific effects on male and female reproductive function, including fertility, that are considered relevant for grouping pesticide residues and for assessing ...

When – and whether – should we spay/neuter companion dogs

Journal of Small Animal Practice, Volume 66, Issue 11, Page 761-766, November 2025.
The recent publication of guidelines for the control of reproduction in dogs and cats shows that a variety of non‐neoplastic and neoplastic conditions occur more commonly in spayed/neutered than entire dogs, and for several of such conditions the earlier the age at surgery – the higher the risk. In addition, unwanted behavioural changes may occur after

The effect of anandamide on uterine nitric oxide synthase activity depends on the presence of the blastocyst. [PDF]

PLoS ONE, 2011
Nitric oxide production, catalyzed by nitric oxide synthase (NOS), should be strictly regulated to allow embryo implantation. Thus, our first aim was to study NOS activity during peri-implantation in the rat uterus.
