Recurrence of Estrous Cycles in the Light-Induced Persistent Estrous Rats by Reserpine

open access: yesEndocrinologia Japonica, 1976
Effect of continuous illumination (LL) on ovarian functions was compared at various ages between the rats exposed to LL from 70 days of age (LL-70) and exposed to LL from the day of birth (LL-0). LL-0 rats retained corpora lutea in their ovaries in higher incidence than LL-70 rats. Effect of reserpine on the restoration of cyclicity was studied in LL-0

Mouse Estrous Cycle Identification Tool and Images

open access: yesPLoS ONE, 2012
The efficiency of producing timed pregnant or pseudopregnant mice can be increased by identifying those in proestrus or estrus. Visual observation of the vagina is the quickest method, requires no special equipment, and is best used when only proestrus or estrus stages need to be identified.

Secretary IgA concentrations and plasma cell count changes associated with the estrous cycle in ewes [PDF]

open access: yes, 2009
Problems statement: The level of uterine Secretory-IgA (S-IgA) and numbers of plasma cells was measured to observe the differences between two stages of estrous cycle (follicular and luteal phase) in the healthy cycling non pregnant ewes.

Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP) Signaling in The Prefrontal Cortex Modulates Cued Fear Learning, But Not Spatial Working Memory, in Female Rats [PDF]

open access: yes, 2018
A genetic polymorphism within the gene encoding the pituitary adenylate cyclase- activating polypeptide (PACAP) receptor type I (PAC1R) has recently been associated with hyper-reactivity to threat-related cues in women, but not men, with post-traumatic ...

Transepithelial electrical resistance (TEER): a functional parameter to monitor the quality of oviduct epithelial cells cultured on filter supports [PDF]

open access: yes, 2015
Cultivation of oviduct epithelial cells on porous filters fosters in vivo-like morphology and functionality. However, due to the optical properties of the filter materials and the cells’ columnar shape, cell quality is hard to assess via light microscopy.

Recovery from Age-Related Infertility under Environmental Light-Dark Cycles Adjusted to the Intrinsic Circadian Period

open access: yesCell Reports, 2015
Female reproductive function changes during aging with the estrous cycle becoming more irregular during the transition to menopause. We found that intermittent shifts of the light-dark cycle disrupted regularity of estrous cycles in middle-aged female ...

The Estrous Cycle and Splenic Erythropoiesis in the Mouse.

open access: yesExperimental Biology and Medicine, 1966
SummaryFerrokinetic and cytologic studies in female mice reveal that splenic eryth-ropoiesis is heightened during proestrus, estrus, and metestrus-1 as compared to met-estrus-2 and diestrus.

Disruption of Estrous Cycles in Exercise-Trained Rats

open access: yesExperimental Biology and Medicine, 1985
The female Sprague-Dawley rat was evaluated as an animal model for the menstrual irregularities that are common in women athletes. Daily vaginal smears revealed that estrous cycles were markedly disrupted in rats during a 10-week exercise training program, while cycles remained normal in sedentary rats.

Pengaruh Ekstrak Daun Sirsak (Annona Muricata L.) terhadap Siklus Reproduksi pada Mencit Putih Dara [PDF]

open access: yes, 1991
The effect of Annona muricata leaves extract on the estrous cycle was studied. Four treatments of this extract were caried out with 0%, 5%, 10% and 15% concentrations respectively.
