The number of elective abortions has been stable for several decades. Many factors explain women's choice of abortion in cases of unplanned pregnancies. Early initiation of contraceptive use and a choice of contraceptive choices appropriate to the woman's life are associated with lower rates of unplanned pregnancies. Reversible long-acting contraceptives should be favored as first-line methods for adolescents because of their effectiveness (grade C). Ultrasound scan before an elective abortion must be encouraged but should not be obligatory (professional consensus)...

Triple-negative breast cancer (TNBC) is one of the most malignant breast cancers currently with a lack of targeted therapeutic drugs. Accumulating evidence supports that KLF5 represents a novel therapeutic target for the treatment of basal TNBC. Our previous studies revealed that mifepristone is capable of suppressing TNBC cell proliferation and promoting cancer cell apoptosis by inhibiting KLF5 expression. Nevertheless, its anticancer efficacy is only modest with high dose. Moreover, its main metabolite N-desmethyl mifepristone with the removal of one methyl moiety results in a significant loss of antiproliferative activity, indicating an important pharmacophore domain around this methyl moiety...

A broad number of natural and synthetic progestins are widely used in human and veterinary therapies. Although progestins exhibit adverse effects in aquatic organisms, information about environmental occurrence and fate have been limited to several compounds, hampering the accuracy of risk assessments of the compounds. In this study, a selective and sensitive analytical method was established to simultaneously determine 19 natural and 42 synthetic progestins in environmental waters, and the synthetic progestins included 19-nortestosterone, 17α-hydroxyprogesterone and progesterone derivatives...

Systemic corticosteroids have been the mainstay of treatment for various hearing disorders for more than 30 yr. Accordingly, numerous studies have described glucocorticoids (GCs) and stressors to be protective in the auditory organ against damage associated with a variety of health conditions, including noise exposure. Conversely, stressors are also predictive risk factors for hearing disorders. How both of these contrasting stress actions are linked has remained elusive. Here, we demonstrate that higher corticosterone levels during acoustic trauma in female rats is highly correlated with a decline of auditory fiber responses in high-frequency cochlear regions, and that hearing thresholds and the outer hair cell functions (distortion products of otoacoustic emissions) are left unaffected...

BACKGROUND: WHO has a pivotal role to play as the leading international agency promoting good practices in health and human rights. In 2005, mifepristone and misoprostol were added to WHO's Model List of Essential Medicines for combined use to terminate unwanted pregnancies. However, these drugs were considered 'complementary' and qualified for use when in line with national legislation and where 'culturally acceptable'. DISCUSSION: This article argues that these qualifications, while perhaps appropriate at the time, must now be removed...

In vertebrates, the early social environment can persistently influence behaviour and social competence later in life. However, the molecular mechanisms underlying variation in animal social competence are largely unknown. In rats, high-quality maternal care causes an upregulation of hippocampal glucocorticoid receptors (gr) and reduces offspring stress responsiveness. This identifies gr regulation as a candidate mechanism for maintaining variation in animal social competence. We tested this hypothesis in a highly social cichlid fish, Neolamprologus pulcher, reared with or without caring parents...

The male gender is more vulnerable to immunological complications of sepsis. Here, we tested the hypotheses that female rats are protected against endotoxemia-evoked hypotension and cardiac autonomic dysfunction, and that gonadal hormone receptors account for such protection. Changes in blood pressure, heart rate, and cardiac sympathovagal balance caused by i.v. lipopolysaccharide (LPS) were determined. In male rats, LPS elevated serum TNFα together with falls in blood pressure and rises in heart rate. The spectral index of cardiac sympathovagal balance (low-frequency/high-frequency ratio, LF/HF) was reduced by LPS, suggesting an enhanced parasympathetic dominance...

This in vitro study investigated the modulatory effect of rifaximin on bovine uterus contractility, in both phases of the oestrous cycle, with and without the steroid hormones that are predominant in the respective phases: oestrogen in the follicular phase and progesterone in the luteal phase. The procedures were conducted in an isolated organ bath by using rifaximin alone (10-4 M) and in association with the steroid hormone antagonists (10-5 M) tamoxifen (oestrogen antagonist) in the follicular phase and mifepristone (progesterone antagonist) in the luteal phase...

BACKGROUND: Expanding access to medication abortion through pharmacies is a promising avenue to reach women with safe and convenient care, yet no pharmacy provision interventions have been evaluated. This observational non-inferiority study investigated the effectiveness and safety of mifepristone-misoprostol medication abortion provided at pharmacies, compared to government-certified public health facilities, by trained auxiliary nurse-midwives in Nepal. METHODS: Auxiliary nurse-midwives were trained to provide medication abortion through twelve pharmacies and public facilities as part of a demonstration project in two districts...

Selective progesterone receptor modulators (SPRMs) are steroid progesterone receptor ligands able to induce agonistic or antagonistic activities. Mifepristone, the class leader, was primarily used for pregnancy termination from the 1980s. Emergency contraception with extended activity was the second major development 30 years later, with mifepristone in some countries and ulipristal acetate world-wide. More recently, ulipristal acetate was released for the treatment of myoma-related uterine bleeding. In addition to a very rapid cessation of bleeding, SPRMs allow a decrease in myoma volume, as do gonadotropin releasing hormone analogs...

Adverse juvenile experiences, including physical abuse, often have negative health consequences later in life. We investigated the influence of social defeat stress exposure as juveniles on neuropsychological behaviors, and the causal role of glucocorticoids in abnormal behaviors and impairment of neurogenesis in mice exposed to the stress. The juvenile (24-day-old) and adult (70-day-old) male C57BL/6J mice were exposed to social defeat stress induced by an aggressive ICR mouse. Social defeat stress exposure as juveniles, even for 1 day, induced persistent social avoidance to the unfamiliar ICR mouse in the social interaction test, but that was not observed in mice exposed to the stress as adults...

As an orally active iron chelator, deferasirox forms its ion complexes in the prepared plasma samples and LC-MS mobile phase where ferric ion exists, and then comparing with the nominal concentration level, a lower detected concentration level of deferasirox would be obtained after LC-MS analysis, if no proper treatment was adopted. Meanwhile, the phenomenon would be observed that multiple repeat injections of the same deferasirox plasma sample in the same tube would show the lower and lower detected concentration levels of deferasirox, which caused by more and more ferric ions from the injection needle dissolved in the sample solution as multiple repeated injections...

This study evaluates the efficacy of mifepristone on weight restoration in rats subjected to dietary restriction and methylphenidate administration. 25 female rats aged between 9 and 12 months were divided into 2 groups: 5 controls (exposed only to dietary restriction) and 20 rats that were administered 5 mg/kg/d of methylphenidate before meal exposure, for 36 days. Among rats who responded to methylphenidate (weight loss of 15-25%) weeks after its administration, a group of 6 rats continued to receive only methylphenidate ("Met" group), and another group received 10 mg/kg/d of mifepristone in addition to methylphenidate for 18 days ("Met+Mif" group; n = 6)...

BACKGROUND: Trabecular meshwork (TM) plays an important role in maintaining normal intraocular pressure (IOP). Studies have shown that glaucomatous TM tissues are stiffer than those of normal tissue. The high expression of fibronectin protein (FN) and adaptor protein (LNK) may be related to high resistance to aqueous humor outflow as well as high IOP. Our concern is what factors lead to the variation of the stiffness of trabecular tissue/cells. METHODS: Atomic force microscope (AFM) and Western blot (WB) analysis were applied to test TM cells of rats cultured with different concentrations of dexamethasone (DEX) and mifepristone (MIF)...

INTRODUCTION: Abortion is often a difficult and traumatic decision for a woman to make. Perhaps greater distress occurs when a woman commences a medical abortion but then changes her mind and wishes to keep the now-threatened pregnancy. One published case series detailed a potential method to counter/reverse the abortifacient effect of mifepristone by administering parenteral progesterone in such situations. OBJECTIVES: The present report details cases of women in similar circumstances who have been treated with progesterone...

Recent studies showed that the circulating stress hormones, epinephrine and corticosterone/cortisol, are involved in mediating ozone-induced pulmonary effects through the activation of the sympathetic-adrenal-medullary (SAM) and hypothalamus-pituitary-adrenal (HPA) axes. Hence, we examined the role of adrenergic and glucocorticoid receptor inhibition in ozone-induced pulmonary injury and inflammation. Male 12-week old Wistar-Kyoto rats were pretreated daily for 7days with propranolol (PROP; a non-selective β adrenergic receptor [AR] antagonist, 10mg/kg, i...

BACKGROUND: Early first-trimester medical abortion (MA) service (≤ 63 days) has been provided by doctors and nurses under doctors' supervision since 2009 in Nepal. This paper assesses whether MA services provided by specifically trained and certified nurses and auxiliary nurse-midwives independently from doctors' supervision, is considered as satisfactory by women as those provided by doctors. METHODS: The data come from a multi-center, randomized, controlled equivalence trial conducted between April 2009 and March 2010 in five district hospitals in Nepal...
