Antimutagenic effects of centchroman--a contraceptive and a candidate drug for breast cancer in multiple mutational assays. (1/25)

Centchroman (CC), a non-steroidal oral contraceptive and a candidate drug for breast cancer, has been reported to exhibit partial to complete remission of lesions in 40.5% of breast cancer patients. The potent anti-oestrogenic activity, negligible side-effects and anti-breast cancer activity of CC prompted us to evaluate the antimutagenic effects of this compound in a bacterial mutagenicity assay and CHO/HPRT and AS52/GPT mutation assays in vitro and in vivo in female Swiss albino mice as measured by both sister chromatid exchange (SCE) and chromosome aberrations (CA) against three known positive mutagen compounds, dimethylbenz[a]anthracene (DMBA), cyclophosphamide (CP) and mitomycin C (MMC). Antimutagenicity assays in Salmonella strains TA97a, TA100, TA98 and TA102 were carried out against commonly used known positive mutagens, sodium azide, 4-nitro-o-phenylenediamine, cumine hydroperoxide, 2-aminofluorene and danthron. A significantly reduced number of bacterial histidine revertant colonies was observed in the plates treated with 0.1, 1, 5 and 10 microg/plate CC and a positive compound when compared with bacterial plates treated with the respective positive compound alone. Ethyl methanesulfonate (EMS), a commonly used positive mutagen for CHO/HPRT and AS52/GPT gene mutation assays, was used for antimutagenicity assay in these cells. CC exhibited protective effects against the mutagenicity of EMS in these two mammalian cell mutation assays, CHO/HPRT and AS52/GPT. In the in vivo studies, pretreatment with CC reduced DMBA-induced SCE and CA and CP- and MMC-induced CA when compared with the group treated only with the positive compounds. These results indicate that CC can reduce the mutagenic effects of known genotoxic compounds.  (+info)

CDB-2914: anti-progestational/anti-glucocorticoid profile and post-coital anti-fertility activity in rats and rabbits. (2/25)

Our goal was to determine the endocrine and post-coital anti-fertility activity of CDB-2914. Concurrent administration of progesterone to rats on day 4 post-mating blocked the anti-fertility activity of a single oral 2 mg dose of CDB-2914. CDB-2914 did not exhibit progestational activity in the oestradiol-primed immature female rabbit at doses that exhibited anti-progestational activity. CDB-2914 antagonized exogenous and endogenous progesterone-stimulated uterine haptoglobin synthesis and secretion in immature and adult mated rabbits respectively. Neither CDB-2914 nor mifepristone exhibited glucocorticoid activity as determined by thymus involution in rats; mifepristone was twice as potent as CDB-2914 in antagonizing glucocorticoid action. Post-coital CDB-2914 treatment resulted in a dose-dependent reduction in implantation sites and pregnancy rates in rabbits. CDB-2914-induced inhibition of uterine weight increase, endometrial glandular arborization and uterine haptoglobin synthesis/secretion correlated with inhibition of pregnancy in mated rabbits. A single oral dose of 64 mg CDB-2914/rabbit was effective at blocking pregnancy when administered on day 4, 5, or 6 post-mating, whereas 32 mg/rabbit was only partially effective in this regard. These data demonstrate that CDB-2914 is a potent, orally active anti-progestin with weak anti-glucocorticoid activity. CDB-2914 inhibited implantation in adult rats and rabbits demonstrating its potential as a post-coital contraceptive drug.  (+info)

A single mid-follicular dose of CDB-2914, a new antiprogestin, inhibits folliculogenesis and endometrial differentiation in normally cycling women. (3/25)

Previous studies in women have shown that the antiprogestin mifepristone delays or inhibits folliculogenesis. The purpose of this study was to explore whether a new analogue, CDB-2914, has similar effects on folliculogenesis, ovulation, or on subsequent luteal phase endometrial maturation. Forty-four normally cycling, healthy women recorded urine LH and vaginal bleeding during pre-treatment, treatment, and post-treatment cycles. At a lead follicle diameter of 14-16 mm, a single oral dose (10, 50, 100 mg) of CDB-2914 or placebo was given, and daily ultrasound, oestradiol and progesterone were obtained until follicular collapse; an endometrial biopsy was obtained 5-7 days later. Single doses of CDB-2914 were well tolerated. Mid-follicular CDB-2914 suppressed lead follicle growth, causing a dose-dependent delay in folliculogenesis and suppression of plasma oestradiol. At higher doses, a new lead follicle was often recruited. Although luteinized unruptured follicles were observed at the 100 mg dose, all women had follicular collapse. There was a significant delay in endometrial maturation after CDB-2914 at all doses. The treatment cycle was lengthened by 1-2 weeks in 30% at 100, 27% at 50 and 9% at 10 mg. CDB-2914 altered ovarian and endometrial physiology without major effects on menstrual cyclicity and may have therapeutic utility.  (+info)

Circulating concentrations of the antiprogestins CDB-2914 and mifepristone in the female rhesus monkey following various routes of administration. (4/25)

The overall aim of these studies was to investigate the oral and i.m. bioavailability of CDB-2914 in intact female rhesus monkeys, and to compare the serum concentrations of CDB-2914 with that of mifepristone following oral administration. In the first study, a 50 mg bolus of CDB-2914 per monkey was administered intravenously, orally or intramuscularly. The area under the serum concentration-time curve for 72 h (AUC(0-72)) following i.v. injection was 18 320 +/- 2718 ng/ml*h, and that for oral administration was 10 464 +/- 3248 ng/ml*h. Thus, the oral bioavailability of CDB-2914 equivalents was 56%. The AUC(0-168 h) following i.m. injection was 11 226 +/- 1130 ng/ml*h. Therefore, the i.m. bioavailability of CDB-2914 equivalents was 62%. In the second study, the serum concentrations of CDB-2914 and mifepristone equivalents were compared following an oral bolus dose in two different formulations. When administered at 5 mg/kg in aqueous suspending vehicle (ASV), the mean peak serum concentration (C(max)) of CDB-2914 equivalents (192 +/- 64 ng/ml) occurred at 5 +/- 1 h, whereas the C(max) of mifepristone equivalents (82 +/- 25 ng/ml) occurred at 3 +/- 1 h. Following administration in gelatin capsules (35 mg/monkey), the C(max) of CDB-2914 equivalents (129 +/- 24 ng/ml) occurred at 5 +/- 1 h, while the C(max) of mifepristone equivalents (31 +/- 8 ng/ml) occurred at 3 +/- 1 h. The serum concentration (AUC(0-120 h)) of CDB-2914 equivalents was 4.7- or 5. 3-fold greater than that of mifepristone equivalents when administered orally in ASV or gelatin capsules respectively. The serum protein binding characteristics of CDB-2914 were also studied. CDB-2914 bound to human alpha(1)-acid glycoprotein (AAG), but not with as high an affinity as mifepristone. In contrast, neither CDB-2914 nor mifepristone bound with high affinity to AAG, corticosteroid binding globulin or sex hormone binding globulin in monkey serum. Collectively, these results indicated that CDB-2914 was more efficiently absorbed than mifepristone following oral administration to female rhesus monkeys.  (+info)

Emergency postcoital contraception. (5/25)

Emergency postcoital contraception, a method used to prevent pregnancy after unprotected sexual intercourse, is a highly effective but underutilized birth control option. Two hormone regimens, ethinyl estradiol (100 microg) with levonorgestrel (0.5 mg) or high-dose levonorgestrel (0.75 mg), given within 72 hours of intercourse and repeated 12 hours later, are available for this purpose. These regimens are packaged as Food and Drug Administration labeled, dedicated products or can be adapted for use from standard oral contraceptive pills. Emergency postcoital contraception should be considered as a primary prevention health service to women of childbearing age.  (+info)

Pharmacokinetic study of different dosing regimens of levonorgestrel for emergency contraception in healthy women. (6/25)

BACKGROUND: Levonorgestrel (LNG) is a commonly used progestin for emergency contraception; however, little is known about its pharmacokinetics and optimal dose for use. METHODS: Serum levels of LNG and sex hormone-binding globulin (SHBG) were measured in five women who received three different regimens: A: 0.75 mg LNG twice with a 12 h interval; B: 0.75 mg twice with a 24 h interval; and C: 1.50 mg in a single dose, with a washout period of 28 days between each treatment. Blood samples were taken before pill intake and at 1, 2, 4, 8 and 12 h after each dose, every 12 h up to day 4 and every 24 h until day 10. LNG and SHBG were measured in all samples. RESULTS: Maximum LNG concentrations were of approximately 27 nmol/l for treatments A and B, and close to 40 nmol/l for treatment C. The area under the curve was significantly higher for treatment C during the first 12 h, and significantly lower for treatment B during the first 24 h. After 48 h and up to 9 days from onset of treatment, serum LNG levels were similar in all three regimens. SHBG levels remained stable for 24 h, decreasing to 60% of the initial value from day 5 until day 10, with no difference between regimens. CONCLUSIONS: The similarity of LNG serum levels obtained with one single dose of 1.5 mg or two doses of 0.75 mg with a 12 h interval justify a clinical comparison of these two regimes.  (+info)

Post-coital administration of levonorgestrel does not interfere with post-fertilization events in the new-world monkey Cebus apella. (7/25)

BACKGROUND: Experimental evidence to disprove the belief that emergency contraception with levonorgestrel (LNG) prevents pregnancy by interfering with post-fertilization events is lacking. Here we determined the effect of post-coital and pre-ovulatory administration of LNG on fertility and ovulation, respectively, in the Cebus monkey. METHODS: To determine the effect on fertility, LNG 0.75 mg or vehicle were administered orally or s.c. once or twice within the first 24 h after mating occurring very close to the time of ovulation. Females that became pregnant were aborted with mifepristone and re-entered the study after a resting cycle until each of 12 females had contributed, in a randomized order, two LNG and two vehicle-treated cycles. To determine the effect on ovulation, LNG 0.75 mg or vehicle were injected twice coinciding with follicles smaller or larger than 5 mm in diameter. Six females contributed five treated cycles each. RESULTS: The pregnancy rate was identical in vehicle- and LNG-treated cycles. LNG inhibited or delayed ovulation only when treatment coincided with a follicle <5 mm diameter. CONCLUSION: In Cebus monkeys, LNG can inhibit or delay ovulation but, once fertilization has taken place, it cannot prevent the establishment of pregnancy. These findings do not support the hypothesis that emergency contraception with LNG prevents pregnancy by interfering with post-fertilization events.  (+info)

Mechanisms of action of mifepristone and levonorgestrel when used for emergency contraception. (8/25)

An emergency contraceptive method is used after coitus but before pregnancy occurs. The use of emergency contraception is largely under-utilized worldwide. One of the main barriers to widespread use is concern about the mechanism of action. Recently, treatment with either 10 mg mifepristone or 1.5 mg of levonorgestrel has emerged as the most effective hormonal method for emergency contraception with very low side-effects. However, the knowledge of the mechanism of action of mifepristone and levonorgestrel in humans, when used for contraceptive purposes and especially for emergency contraception, remains incomplete. The objective of this review is to summarize available data on the effects of mifepristone and levonorgestrel on female reproductive functions relevant to the emergency use of the compounds. When summarized, available data from studies in humans indicate that the contraceptive effects of both levonorgestrel and mifepristone, when used in single low doses for emergency contraception, involve either blockade or delay of ovulation, due to either prevention or delay of the LH surge, rather than to inhibition of implantation.  (+info)

A striking feature of most bioethical discussion about patient autonomy is their exclusive focus on individual patients; this pattern mirrors medicines consistent tendency to approach illness as primarily a problem of particular patients. Similar problems are associated with each discipline. Within the medical tradition, suffering is located and addressed in the individuals who experience it rather than in the social arrangements that may be responsible for causing the problem. Instead of exploring the cultural context that tolerates and even supports practices such as war, pollution, sexual violence, and systemic unemployment - practices that contribute to much of the illness that occupies modern medicine - physicians generally respond to the symptoms troubling particular patients in isolation from the context that produces these conditions.

Written By Johanna Ahola-Launonen. University of Helsinki. In bioethical discussion, it is often debated whether or not some studies espouse genetic determinism. A recent study by Tuomas Aivelo and Anna Uitto[1] give important insight to the matter. They studied main genetics education textbooks used in Finnish upper secondary school curricula and compared the results to other similar studies from e.g. Swedish and English textbooks. The authors found that gene models used in the textbooks are based on old Mendelian law-based gene models not compatible with current knowledge on gene-gene-environment-interaction. The authors also identified several types of genetic determinism, that is, weak determinism and strong determinism, which both were present in the textbooks. The somewhat intuitive remark is that genetic education has to have a strong trickle-down effect on how people understand genes, and that we should be careful not to maintain these flawed conceptions. Furthermore, it would be ...
The LNG processing plant will have a capacity of 15.5mt/y of gas and 1mt/y of condensate. It will include three LNG trains, storage and loading facilities.. Due to the extreme climatic conditions in the region, construction of the LNG project is planned to be carried out through modular methods.. Erection of the facilities for field development presents some challenges due to the permafrost conditions in the region.. Due to permafrost, the underground layer of soil stays frozen for at least two years. The layer above it freezes and thaws with change in season.. As a result, the infrastructure cannot come in contact with this soil to ensure stability. In such conditions, the infrastructure is usually erected on stilts. A liquefaction technology suitable for these conditions will be chosen for the LNG plant.. The LNG loading / unloading tankers will have a deadweight of between 183,000t and 208,000t. They will be of ice-class and be able to operate in the harsh climatic conditions of the Yamal ...

Post-Coital Dysphoria goes by a few names including, post-sex blues, La Petite Mort and post-coital tristesse. It is a condition that gives people, immediately after a good sexual experience, an overall feeling of great sadness, upset or anxiety. This problem is generally not associated with the relationship and was thought to affect more men than women. This is caused mainly by prolactin hormones which work to counteract the sexual arousal hormone dopamine. In normal situations the prolactin kicks in after an orgasm is achieved, thus promoting a feeling of wellbeing and tranquillity, the main reason why men fall asleep. High amounts of this particular hormone can also cause impotence as they overshadow the initial dopamine effect and also cause post-coital dysphoria. Male impotence, known as Erectile Dysfunction can be treated successfully with medication such as Viagra (sildenafil) and Cialis (tadalafil) under the supervision of a doctor.. The refractory period (time between orgasms) is also ...
Median (range). Effect of food: Administration of ella together with a high-fat breakfast resulted in approximately 40 - 45% lower mean Cmax, a delayed tmax (from a median of 0.75 hours to 3 hours) and 20 - 25% higher mean AUC0-∞ of ulipristal acetate and monodemethyl-ulipristal acetate compared with administration in the fasting state. These differences are not expected to impair the efficacy or safety of ella to a clinically significant extent; therefore, ella can be taken with or without food.. Distribution Ulipristal acetate is highly bound (, 94%) to plasma proteins, including high density lipoprotein, alpha-l-acid glycoprotein, and albumin.. Metabolism Ulipristal acetate is metabolized to mono-demethylated and di-demethylated metabolites. In vitro data indicate that this is predominantly mediated by CYP3A4. The mono-demethylated metabolite is pharmacologically active.. Excretion The terminal half-life of ulipristal acetate in plasma following a single 30 mg dose is estimated to 32.4 ± ...

Ulipristal acetate is a new method of treating fibroids that have moderate to severe symptoms. Its only recommended for women over 18 years of age.. The treatment involves taking one tablet orally (by mouth) once a day, with a course of treatment lasting up to three months. During this time you shouldnt bleed and your fibroids will shrink.. After the initial course of treatment, you wait to see what your first two periods are like while not taking treatment. If theyre still heavy, another three month course of ulipristal acetate may be recommended.. Treatment should only be started when menstruation (monthly periods) have occurred. The first course of treatment should start during the first week of menstruation. Your doctor will be able to explain how long the intervals between treatment courses should be.. If youre taking a course of ulipristal acetate and you miss a dose, you should take a dose as soon as possible. However, if the dose was missed by more than 12 hours, you shouldnt take ...
Summer is like the post-coital feeling - not everyone takes to it after the lovely splash of spring and the bygone chilly days. Though the post-coital session evokes warmth and a sense of fulfilment, it cannot compare to coitus itself. Period. The sweat and the addendum to it makes it a tad difficult for me but then there are some bright spots (literally and metaphorically) to summer. The appearance of water/musk melons, pepsi-colas and other summery delights alleviate the problem of post-spring/winter melancholia partially. Summer also signals the end of the semester and examination blues. I thought after becoming a teacher, I would be free from the end-of-term low tide but looks like the end always comes with a sting of boredom, a sense of forlornness and loneliness of having to bid adieu to a set of students with whom the year was spend in wanton abandon, endless gossip, conniving moments and of course some lessons. I will miss them and that feeling makes me a bit morose ...

Objectives: To characterize and describe treatment with Ulipristal acetate (UPA) in a pre-operative setting and to evaluate the safety, effectiveness, and Health Related Quality of Life (HRQoL) outcomes in a population treated according to standard clinical practice in the EU. Study design: Multi-centre, prospective, non-interventional study (PREMYA) of patients diagnosed with moderate to severe symptoms of uterine fibroids and undergoing a pre-operative treatment with UPA (Esmya (R)) at 73 clinical practice sites within the EU. Patients were followed during UPA treatment and for 12 months after treatment discontinuation for a total of 15 months follow-up. Data was collected every 3 months in accordance with standard care visits. Results: A total of 1568 women were enrolled, of whom 1473 were found to be eligible for data analysis. Only 38.8% of patients underwent surgery, of which the majority were of a conservative/minimally invasive nature. Physicians assessments of patients overall ...

Apical surfaces of human endometrial epithelium and endothelium are key elements for the initiation of molecular interactions to capture the blastocyst or leukocyte, respectively. The L-selectin adhesion system has been strongly proposed to play an important role in the initial steps of trophoblast adhesion and promotion of integrin-dependent processes, ultimately culminating in the establishment of the embryo-maternal interface. On the basis of these facts, we hypothesized a novel role for pinopodes as the first embryo-fetal contact sites to contain the highest subcellular expression of L-selectin ligand suggesting its role in early adhesion as predicted. Thus, the objective of this study was therefore to determine the subcellular pattern of distribution of the L-selectin ligand (MECA-79) in human endometrial apical membrane region during the window of implantation. Endometrial biopsies of secretory phases from fertile females ranging in age between 25 and 42years were studied using several approaches,

In May, Shell revealed it has been in talks with Anadarko about acquiring a stake in its Mozambique fields, but had pulled back because the asking price was too high. Mr. Guebuza said Thursday that he wants Mozambiques first LNG exports to start shipping in 2018, an ambitious deadline in a country that has no established oil and gas industry and limited infrastructure. Shells floating LNG vessels produce, liquefy and transfer gas to tankers for export, removing the need for a costly and complex onshore terminal. The technology is being used on a project in Australia with a similar five-year development schedule and could be one solution for Mozambique, said Mr. Steenson. Shell took the decision to deploy a $10 billion floating LNG vessel on Australias Prelude field in 2011 and it is due to start operating late in 2016 or early in 2017, said Mr. Steenson. The Prelude vessel, the first of its kind in the world, will produce around 5.3 million tpy of LNG and condensate, he said. At present, the ...
