Morphological changes of the hippocampal astrocytes at different phases of the estrous cycle in female mice

, 2015
Background: Usual fluctuations of sex hormones during the estrous cycle in female mice affect the hippocampal neurogenesis. The hippocampus also comprises many steroid receptors suggesting the modulatory effects of gonadal hormones on the hippocampal ...

Granulosa Cell Tumour in a Spayed Cat With Ovarian Remnant Syndrome and Hyperestrogenaemia Without Estrus Signs

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Granulosa cell tumour arising from ovarian remnant tissue can occur in spayed cats without overt estrus signs, despite marked hyperestrogenaemia. In this case, CT showed a large abdominal mass contiguous with ovarian vasculature; surgery and histopathology confirmed granulosa cell tumour with hepatic metastasis.

Chemogenetic Stimulation of the Dorsal Motor Nucleus of the Vagus Mitigates Autonomic Dysfunction and Memory Decline in Rat Model of Alzheimer‐Like Disease

Acta Physiologica, Volume 242, Issue 7, July 2026.
ABSTRACT Aim To test the hypothesis that Alzheimer‐like metabolic neurodegeneration rat model leads to an autonomic dysfunction, memory impairment, and hippocampal amyloid pathology and that long‐term chemogenetic stimulation of the dorsal motor nucleus of the vagus reverses these alterations. Methods Male and female transgenic Long Evans rats received

Cortisol and heart rate response of mares during the in‐hand breeding procedure with and without restraint

Equine Veterinary Journal, Volume 58, Issue 4, Page 1116-1126, July 2026.
Abstract Background In‐hand breeding involving restraint methods is likely the most common practice in the horse breeding industry worldwide. However, welfare issues that arise from such management have not been investigated in detail. Objectives (1) To investigate whether the mares show increased stress responses during in‐hand breeding using (a) a ...

Unravelling the Genetic Mechanisms of Litter Traits in a Maternal Line of Pigs

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 560-580, July 2026.
ABSTRACT Reproductive traits related to litter size are the main indicators of reproductive efficiency in pig production and are continuously evaluated for the selection of maternal lines. Several environmental and genetic factors are involved with the development of these traits.

Male influence on estrous cycle phenomena in the rat

, 1978
Sixty-four colony-bred Sprague-Dawley female rats were used in examining the effect of the male presence on female estrous cycle interval. Females were randomly assigned 4 per cage to 16 cages.
