Dexamethasone (DEX), a synthetic glucocorticoid, has been used to treat respiratory distress syndrome in prematurely born infants. Despite the important short-term benefit on lung function, there is growing concern about the long-term outcome of this treatment, since follow-up studies of prematurely born infants have shown lasting adverse neurodevelopmental effects. Since the mechanism underlyi...

Early life adversity has a profound impact on brain development and later life health. Animal models have provided insight how early life stress programs stress responsiveness and might contribute to the development of psychiatric disorders. In the present study, the long-term effects of maternal deprivation (MD) on behavioral inhibition and attention were examined in adult male Wistar rats. To...

Previous research has shown that mifepristone can prevent and reverse weight gain in animals and human subjects taking antipsychotic medications. This proof-of-concept study tested whether a more potent and selective glucocorticoid receptor antagonist could block dietary-induced weight gain and increase insulin sensitivity in mice. Ten-week-old, male, C57BL/6J mice were fed a diet containing 60...

The objective: to conduct a comparative analysis of the efficacy and tolerability antigestagens (mifepristone) gonadotropin-releasing hormone agonists (aGnRH) as part adjuvant therapy for prevention recurrence uterine fibroids after conservative myomectomy in women reproductive age.Materials methods. study included 99 patients age (19–42 years old) with myoma. were divided into three groups (n=...

Medical abortion is not recognized as a high-risk factor for invasive pelvic infection. Here, we report two cases of group A Streptococcus (GAS; Streptococcus pyogenes) endometritis following medical abortions with a protocol of oral mifepristone and misoprostol.

Second trimester abortion remains a common procedure worldwide. Dilatation and evacuation (D&E) is the surgical method of choice, if the surgical expertise and facilities are available. Adequate cervical dilatation preoperatively is a prerequisite for a safe D&E. Medical abortion using misoprostol together with mifepristone is the medical method of choice. The recommended regimen is 200mg mifep...

This article presents results from a small, introductory clinical study offering a simplified regimen medical abortion to women in Turkey. A total of 208 women from five sites were recruited from July 2000 through March 2001. All eligible consenting women were given 200 mg oral mifepristone at the clinic followed by 400 microg oral misoprostol 2 days later either at home or at the clinic. The o...

Background Rats emit 50-kHz ultrasonic vocalizations (USVs) to communicate positive emotional states, and these USVs are increasingly being investigated in preclinical studies on reward and motivation. Although it is the activation of dopamine receptors that initiates the emission of 50-kHz USVs, non-dopaminergic mechanisms may modulate calling in the 50 kHz frequency band. To further elucidate...

Here we report a new transgenic expression system by combination of liver-specific expression, mifepristone induction and Cre-loxP recombination to conditionally control the expression of oncogenic kras(V12). This transgenic system allowed expression of kras(V12) specifically in the liver by a brief exposure of mifepristone to induce permanent genomic recombination mediated by the Cre-loxP syst...
