BACKGROUND Improvement of neurologic outcome in progesterone-administered patients with diffuse axonal injury (DAI) has been found in a recent study. Also, there has been interest in the importance of serum parameters as predictors of outcome in traumatic brain injury. OBJECTIVES The aim of this study was to examine the effect of progesterone administration on serum levels of neuron-specific ...

Progesterone was extracted from leaves and subterranean parts o f Convallaria majalis L. and quantified by radioimmunoassay. During the stage o f flowering the content o f progesterone in rhizomes was by a factor o f four higher than in leaves and by a factor o f ten higher than in roots, whereas five weeks later the level o f progesterone was unchanged in rhizomes and roots but was elevated in...

BACKGROUND Polycystic ovarian syndrome is one of the most common causes of endocrine disorders and main reason of infertility due to anovulation and recurrent abortions. Progesterone has been shown to have an important role in fertilization of oocyte and fetal implantation. OBJECTIVE The purpose of this study was to compare the predictive value of progesterone level on IVF success in women wi...

i read with interest the papers written by peyghambari et al (2008) and niknafs et al   nd   et al   et al   et al   et al   et al   et al   et al   (1994) did not observe any   advantage in the pregnancy rates when adding estrogen+progesterone at luteal phase in patients undergoing ivf (6). in conclusion, the mechanism of luteal phase support in assisted reproduction is complex and a controver...

Findings from previous studies of hormone-mediated behavior in women suggest that raised progesterone level increases the probability of behaviors that will reduce the likelihood of disruption to fetal development during pregnancy (e.g. increased avoidance of sources of contagion). Here, we tested women's (N=52) sensitivity to potential cues to nearby sources of contagion (disgusted facial expr...

BACKGROUND/OBJECTIVE To verify whether progesterone concentration is changed in the maternal serum of intra-uterine growth retardation (IUGR) pregnancies and to assess if there is a relationship between maternal progesterone and fetal Doppler velocimetry. PATIENTS AND METHODS Thirty-five patients with intrauterine growth retardation infants and thirty-seven pregnant women with appropriate for...

To gain an insight into intracellular mechanisms involved in differentiation of human endometrial cells into decidual cells, we examined the presence of Akt, an emerging intracellular mediator in human endometrial stromal cells (ESC). We explored the mechanisms regulating Akt phosphorylation during the process of progesterone-induced decidualization using a primary cell culture system of ESC. B...

The mechanism of progesterone inhibition of casein gene expression was analyzed in a two-step culture model of the whole mammary organ of the mouse. Cellular accumulation of casein mRNA (mRNA,.,) was used as a measure of casein gene expression. A specific mouse casein cDNA (cDNA,.,) was used as a hybridization probe to monitor mRN&,,, in the glands. Six days of step I incubation in medium conta...

In bovine luteal cells, progesterone can directly affect its own synthesis by increasing the activity of 3β-HSD. The effect of progesterone on its own secretion coincides with increased expression of the genes for 3βHSD, StAR, and cytochrome P450scc. Therefore, progesterone regulates its own synthesis by affecting the activity of the enzymes that take part in luteal steroidogenesis, and also by...
