White box: estrous (5 female controls, 4 HD group, and 6 MS group), gray box: diestrus
(6 female controls, 2 HD group, and 1 MS group).
(A) proestrus, (B) estrus, (C) metestrus, (D) diestrus

Indeed, cDCs generated in the absence of E2 produced moderate levels of IL-12p70 and undetectable levels of TNF[alpha], while those generated in diestrus
levels of E2 responded to CpG by producing significantly higher amounts of IL-12p70 and TNF[alpha], similar to those that we see in cDCs generated in the presence of a standard fetal bovine serum containing physiological levels of hormones [44, 45].
Sampling was conducted at early lactation on day-60 postpartum, day-82 and day-105 during the diestrus
phase of the estrus cycle.
But the message doesn't seem to transmit during diestrus
, when levels of the hormone progesterone are high.
At a lower dose (50 mg/kg BW), the extract produced an anti-oestrogenic effect, inhibiting implantation with cessation of the oestrous cycle and continuous diestrus
, suggesting secretion of oestrogen from the ovary was not occurring.
Respectively, cell body size (referring to soma and perikaryon) of MPOA neurons has been shown to be increased in late pregnant rats when compared to ovariectomized or diestrus
During the luteal phase of menstrual cycle and diestrus
stage of oestrous cycle, stromal cells proliferate and differentiate into decidual cells which then produced various factors that help to prepare endometrium for blastocyst adhesion and subsequently trophoblast invasion.
Rats were divided into three groups: male rats (male group, n = 8), rats in the estrus phase (estrus group, n = 8) and animals in the diestrus
phase on day 1 (diestrus
group, n = 8).
An irregularity in cycle pattern was observed with an increase (p < 0.05) in the diestrus
phase and a decrease in the proestrus (p < 0.05), metestrus,
The hormonal and reproductive cycle of female rats, called estrus cycle, lasts about four-five days and consists of four distinct phases: proestrus, estrus, metaestrus and diestrus
. The characterization of each phase is based on the proportion among three types of cells observed in a vaginal smear: epithelial cells, cornified cells and leukocytes.
The 17[beta]-estradiol concentrations of one female, proestrus 77.26 [+ or -] 20.71pg/ml (62.6291.91pg/ml), estrus 82.24 [+ or -] 10.96pg/ml (74.4990pg/ml), metestrus 75.88pg/ml, diestrus
85.74 [+ or -] 13.59pg/ml (71.93-109.37pg/ml), were low when compared to the samples mentioned above (Fig.
