The mixed legacy of the rat estrous cycle [PDF]

open access: yesBiology of Sex Differences, 2023
Background The rat estrous cycle first characterized by Long and Evans in 1922 profoundly affected the course of endocrine research. Investigators took advantage of sex steroid hormone fluctuations associated with the cycle to assess hormonal influences ...

Why the estrous cycle matters for neuroscience [PDF]

open access: yesBiology of Sex Differences, 2022
Background Ovarian hormone fluctuations over the rodent estrous cycle and the human menstrual cycle are known to significantly impact brain physiology and disease risk, yet this variable is largely ignored in preclinical neuroscience research, clinical ...

Relationship of the Estrous Cycle to Milk Composition

open access: bronzeJournal of Dairy Science, 1979
The relationship of the estrous cycle to milk composition was examined in 15 Holstein cows in first lactation which were approximately 45 days postpartum. Composite milk samples were collected twice daily and analyzed for progesterone, fat, protein, total solids, sodium, potassium, magnesium, calcium, and somatic cells.

Determination of the rat estrous cycle vased on EfficientNet. [PDF]

open access: yesFront Vet Sci
In the field of biomedical research, rats are widely used as experimental animals due to their short gestation period and strong reproductive ability. Accurate monitoring of the estrous cycle is crucial for the success of experiments. Traditional methods are time-consuming and rely on the subjective judgment of professionals, which limits the ...

Validation of a mathematical model of the bovine estrous cycle for cows with different estrous cycle characteristics

open access: yesAnimal, 2017
A recently developed mechanistic mathematical model of the bovine estrous cycle was parameterized to fit empirical data sets collected during one estrous cycle of 31 individual cows, with the main objective to further validate the model.

Whole Transcriptome Analysis: Implication to Estrous Cycle Regulation [PDF]

open access: yesBiology, 2021
Estrous cycle is one of the placental mammal characteristics after sexual maturity, including estrus stage (ES) and diestrus stage (DS). Estrous cycle is important in female physiology and its disorder may lead to diseases, such as polycystic ovary ...

Behaviors Related to Psychiatric Disorders and Pain Perception in C57BL/6J Mice During Different Phases of Estrous Cycle

open access: yesFrontiers in Neuroscience, 2021
Robust sex difference among humans regarding psychiatry- and pain-related behaviors is being researched; however, the use of female mice in preclinical research is relatively rare due to an unchecked potential behavioral variation over the estrous cycle.

The impact of the ovarian cycle on anxiety, allopregnanolone, and corticotropin releasing hormone changes after motherhood in female rats and women

open access: yesTranslational Psychiatry, 2023
Fluctuations in ovarian steroids across the estrous and menstrual cycle in female rats and women, respectively, are associated with changes in anxiety. Pregnancy causes long-term changes to ovarian hormone release, yet research on estrous- and menstrual ...
