The objective of this investigation was to study short-term efficacy and feasibility of a new progestogen-only treatment for outpatient management of acute abnormal uterine bleeding. This was a prospective, single-arm, pilot clinical trial of a progestogen-only bridging treatment for acute abnormal uterine bleeding in nonpregnant, premenopausal women in the Gynecologic Urgent Care Clinic at Harbor-UCLA Medical Center. Subjects were administered a depo-medroxyprogesterone acetate 150 mg intramuscular injection and given medroxyprogesterone acetate 20 mg to be taken orally every 8 hours for 3 days. The primary outcome measures included a percentage of women who stopped bleeding in 5 days, time to bleeding cessation, reduction in numbers of pads used, side effects, and patient satisfaction. All 48 women stopped bleeding within 5 days; 4 women had spotting only at the time of their last contact during the 5 day follow-up. Mean time to bleeding cessation was 2.6 days. Side effects were infrequent and patient satisfaction was high. Injection of depo-medroxyprogesterone acetate 150 mg intramuscularly combined with 3 days of oral medroxyprogesterone acetate 20 mg every 8 hours for 9 doses is an effective outpatient therapy for acute abnormal uterine bleeding.

The artificial recharge of aquifers has become a valuable tool to increase water resources for drinking water production in many countries. In this work a total of 41 organic pollutants belonging to the classes of pesticides, estrogens, progestogens and volatile organic compounds (VOCs) have been monitored in the water from two artificial recharge plants located in Sweden and Denmark. The results from two sampling campaigns performed in each plant indicate good chemical status of the source water, as the contaminants detected were present at very low levels, far from those established in the legislation as maximum admissible concentrations (when existing) and far from those considered as a risk. Thus, of the 17 pesticides investigated, BAM (2,6-dichlorobenzamide), desethylatrazine, simazine, atrazine, terbuthylazine, diuron, metolachlor, and diazinon were the only compounds detected, and total pesticides levels were below 25ng L(-1), respectively. Estrone-3-sulfate was the only estrogen detected, at concentrations lower than 0.5ng L(-1). Progestogens were not found in any sample. Detected VOCs (benzene, toluene, ethylbenzene, and trichloroethylene) were below 0.04microg L(-1). The efficiency of elimination of these organic contaminants was poor as no significant decrease in their concentrations was observed through the recharge process.

[Effects of progestogens on the metabolism of lipids and carbohydrates. Practical consequences (author's transl)].

Estrogens which are one of the components of contraceptive less than pills greater than are incriminated in many cardiovascular accidents. These occur as a result of metabolic disorders (involving lipids and carbohydrates), of modifications in coagulation factors, etc. The possible influence of progestogens was ignored for a long time. The widespread use of these compounds, prescribed for contraception as well as during hormonal replacement therapy for absolute or relative luteinic insufficiency, makes careful monitoring of lipid and carbohydrate metabolism imperative. This position is strengthened by a preliminary review of the literature which leads to several conclusions concerning lipid and carbohydrate metabolism.

To examine the effect of short-term progestogen treatment on androgen, gonadotropin, and sex hormone-binding globulin (SHBG) levels in oligomenorrheic women. Comparative study of changes in hormonal parameters in patients with or without ultrasonographically diagnosed polycystic ovarian disease (PCOD). Open patient clinic of reproductive endocrinology at University Central Hospital of Turku, Finland. Seventy-five oligomenorrheic women with (n = 51) or without (n = 24) PCOD. Serum concentrations of testosterone (T), androstenedione (A), dehydroepiandrosterone sulfate, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and SHBG. The levels of T, A, LH, and the LH:FSH ratios decreased significantly after oral treatment with medroxyprogesterone acetate (10 mg/d for 10 days) in non-PCOD women and in women with PCOD decreasing the frequencies of pathological laboratory findings, in particular elevated levels of LH:FSH ratio and A in PCOD women and of LH:FSH ratio in non-PCOD women. The levels of T, A, and LH as well as the LH:FSH ratio were significantly higher in women with PCOD. Obesity was associated with high free androgen indices, low LH:FSH ratios, and low concentrations of LH, A, and SHBG. The serum samples for hormonal analyses used as an aid in diagnosing PCOD should be obtained without pretreatment with progestogen because it masks the biochemical findings of PCOD.

OBJECTIVES: Progestogen-only pills (POPs) are safer with respect to cardiovascular risks than contraceptives containing estrogens. Despite the increased contraceptive efficacy of a desogestrel-only pill compared with a traditional POP, POPs are still not widely used due to an unpredictable bleeding...... pattern. A new POP containing 4 mg drospirenone has been developed with a 24/4 intake regimen which may improve the bleeding pattern. The objectives of this study were to investigate ovulation inhibition with the new drospirenone-only pill in comparison with the desogestrel-only pill and, in addition......, to assess the effects on cervical mucus permeability and bleeding. METHODS: Sixty-four healthy volunteers with proven ovulatory cycles were randomised and treated with either the drospirenone-only or the desogestrel-only pill during two 28-day cycles.

SummaryThis work investigated the presence of 21 emerging contaminants of various chemical groups (7 estrogens, 3 progestogens, 6 pharmaceuticals and personal care products (PPCPs), and 5 acidic pesticides) in the Llobregat river basin (NE Spain). Waters from the outlet of various sewage treatment plants (STP) and waterworks located along the river basin, as well as water samples from the river or its tributaries upstream and downstream of these plants were analysed in two pilot monitoring studies. Chemical analyses were performed by means of on-line or off-line solid-phase extraction followed by liquid chromatography-electrospray-tandem mass spectrometry. Methods detection limits (in ng/L) were ⩽0.85 for estrogens, ⩽3.94 for progestogens, ⩽30 for PPCPs, and ⩽0.99 for pesticides. Of the estrogens and progestogens analysed, only estrone-3-sulfate, estrone, estriol and progesterone were found to be present in the low nanogram per liter range in some of the samples investigated. Except for atenolol, all PPCPs studied (ibuprofen, diclofenac, clofibric acid, salicylic acid, and triclosan) could be identified at levels usually lower than 250 ng/L and up to 1200 ng/l (diclofenac). Of the various pesticides investigated (2,4-D, bentazone; MCPA, mecoprop and propanil) MCPA and 2,4-D were the most ubiquitous and abundant and bentazone the only one not detected. Individual concentrations were most often below 100 ng/L and never surpassed the EU limits.

From 1976 to 1985, 402 patients with primary lung cancer were treated with radiotherapy at our hospital. There were 75 female patients who formed the basis of our analysis. Comparing the characteristics of female and male patients, the predominant characteristics of the female patients were as follows; 1) larger proportion of the patients with adenocarcinoma, 2) higher percentage of stage 4 patients, 3) lower average age, 4) better performance status (PS), 5) lower frequency of lethal complications, and 6) higher frequency of more than two admissions. The prognosis of female patients was better than that of males. The favorable characteristics of female patients for prognosis, were lower average age, better PS, and lower frequency of lethal complications. A higher frequency of admission to hospital might be a favorable characteristics for female patients to extend survival in patients with recurrence disease. (author)

Breast cancer and steroid metabolizing enzymes: the role of progestogens.

Science.gov (United States)

Pasqualini, Jorge R

2009-12-01

It is well documented that breast tissue, both normal and cancerous, contains all the enzymatic systems necessary for the bioformation and metabolic transformation of estrogens, androgens and progesterone. These include sulfatases, aromatase, hydroxysteroid-dehydrogenases, sulfotransferases, hydroxylases and glucuronidases. The control of these enzymes plays an important role in the development and pathogenesis of hormone-dependent breast cancer. As discussed in this review, various progestogens including dydrogesterone and its 20alpha-dihydro-derivative, medrogestone, promegestone, nomegestrol acetate and norelgestromin can reduce intratissular levels of estradiol in breast cancer by blocking sulfatase and 17beta-hydroxysteroid-dehydrogenase type 1 activities. A possible correlation has been postulated between breast cell proliferation and estrogen sulfotransferase activity. Progesterone is largely transformed in the breast; normal breast produces mainly 4-ene derivatives, whereas 5alpha-derivatives are most common in breast cancer tissue. It has been suggested that this specific conversion of progesterone may be involved in breast carcinogenesis. In conclusion, treatment with anti-aromatases combined with anti-sulfatase or 17beta-hydroxysteroid-dehydrogenase type 1 could provide new therapeutic possibilities in the treatment of patients with hormone-dependent breast cancer.

The present study evaluated changes of fecal sexual steroids in two female cheetahs (Geijsha and Duchessa) in Northern Italy throughout one year. Wet feces were collected daily from two sibling animals of the same age, housed with conspecific males and managed in the same conditions, and estrogens and progestogens concentrations were analyzed by radioimmunoassay (RIA). Evidence of ovarian activity based on regular fluctuation in estrogen excretion was demonstrated in both females. None of the animals was continuously cycling, as follicular activity was interrupted by anestrous periods, during the spring and early winter. No significant increases of progestogens were recorded after the estrogen peaks, indicating that induced or spontaneous ovulations did not occur during the observation period. The wavelet decomposition evidenced the temporal pattern of ovarian activity in the two females, underlying throughout the year a more pronounced rhythmical ovarian estrogenic activity in Geijsha than in Duchessa. However, this statistical approach had a smoothing effect in depicting the hormonal patterns and the number of follicular phases might be lower than that revealed by the iterative method. In this study, RIA on wet feces performed very well to determine sexual steroid concentrations, and an ovarian activity interrupted by anestrous periods along the year in captive cheetahs co-housed in a small group was demonstrated. More information on estrous behavior of captive cheetahs were obtained in this study, but the effects of husbandry and management conditions on natural reproductive physiology of this species remain to elucidate.

The progestogen 17-α hydroxyprogesterone caproate (17-OHPC) is 1 of only 2 agents recommended for clinical use in the prevention of spontaneous preterm delivery, and studies of its efficacy have been conflicting. We have developed an in-vitro model to study the fetal membrane weakening process that leads to rupture in preterm premature rupture of the fetal membranes (pPROM). Inflammation/infection associated with tumor necrosis factor-α (TNF-α) induction and decidual bleeding/abruption associated thrombin release are leading causes of preterm premature rupture of the fetal membranes. Both agents (TNF-α and thrombin) cause fetal membrane weakening in the model system. Furthermore, granulocyte-macrophage colony-stimulating factor (GM-CSF) is a critical intermediate for both TNF-α and thrombin-induced fetal membrane weakening. In a previous report, we demonstrated that 3 progestogens, progesterone, 17-alpha hydroxyprogesterone (17-OHP), and medroxyprogesterone acetate (MPA), each inhibit both TNF-α- and thrombin-induced fetal membrane weakening at 2 distinct points of the fetal membrane weakening pathway. Each block both the production of and the downstream action of the critical intermediate granulocyte-macrophage colony-stimulating factor. The objective of the study was to characterize the inhibitory effects of 17-OHPC on TNF-α- and thrombin-induced fetal membrane weakening in vitro. Full-thickness human fetal membrane fragments from uncomplicated term repeat cesarean deliveries were mounted in 2.5 cm Transwell inserts and cultured with/without 17-alpha hydroxyprogesterone caproate (10 -9 to 10 -7 M). After 24 hours, medium (supernatant) was removed and replaced with/without the addition of tumor necrosis factor-alpha (20 ng/mL) or thrombin (10 U/mL) or granulocyte-macrophage colony-stimulating factor (200 ng/mL). After 48 hours of culture, medium from the maternal side compartment of the model was assayed for granulocyte-macrophage colony

Antiandrogenic and antimineralocorticoid health benefits of COC containing newer progestogens: dienogest and drospirenone.

Science.gov (United States)

Regidor, Pedro-Antonio; Schindler, Adolf E

Data have demonstrated that COCs, besides offering a satisfactory and safe contraception, offer a variety of non-contraceptive health benefits and therapeutic positive aspects. Many prescribes and users, however, do not realize these positive aspects especially the non-contraceptive health benefits. While the contraceptive use is the primary indication for COC use for most women, these users should be advised in regard of the non-contraceptive benefits when contraception is discussed and prescribed. Using COCs specifically for non-contraceptive indications is an off-label use in many clinical situations (only some exceptions as e.g. acne vulgaris in some countries are allowed clinical entities for the use of these drugs). Therefore, appropriate discussions with the patient regarding this fact should performed and documented by the prescribing physicians. Independent of the off-label situation, COCs containing the newer progestogens dienogest and drospirenone with their antiandrogenic and antimineralocorticoid health benefits play an important role in the management of many diseases and their use should therefore be considered by clinician's. This review will focus on the effects of these COCs on the endometrium, the skin, the fat tissue and the premenstrual syndrome.

Advances in pharmacotherapy for treating female sexual dysfunction.

Science.gov (United States)

Nappi, Rossella E; Cucinella, Laura

'Female sexual dysfunction' (FSD) is an umbrella term comprising a range of common disorders, including hypoactive sexual desire, reduced subjective and/or physical genital arousal (poor sensation, vasocongestion, lubrication), sexual pain and inability to achieve orgasm/satisfaction, which are multidimensional by nature and often coexisting. Psychological and contextual factors have a significant influence on organic components of sexual response and behavior and a tailored medical approach to sexual symptoms is inevitably limited. The paper reports the most recent advances in pharmacotherapy for women taking into account the biopsychosocial model. Hormone therapy, including estrogens, testosterone, tibolone and dehydroepiandrosterone, are discussed in term of efficacy and safety in postmenopausal women both for female sexual interest/arousal disorder (FSIAD) and genito-pelvic pain/penetration disorder. Ospemifene, a selective estrogen receptor modulator, approved to treat dyspareunia at menopause, is also discussed. Data on psychoactive agents for treatment of FSIAD in premenopausal women are discussed, including the potential use of on-demand combined hormonal (testosterone) and non-hormonal (buspirone or sildenafil) treatments to address possible neurophysiological profiles of women. We are still waiting for an approved pharmacotherapy for FSD. This is not the result of gender inequality in sexual medicine, but it reflects the need of balancing benefits and risks in order to provide effective and safe treatments to women of any age.

Reproductive success of endangered whooping cranes (Grus americana) maintained ex situ is poor. As part of an effort to identify potential causes of poor reproductive success in a captive colony, we used non-invasive endocrine monitoring to assess gonadal and adrenal steroids of bird pairs with various reproductive outcomes and evaluated the relationships of hormones and behaviors to reproductive performance. Overall, reproductively successful (i.e., egg laying) females had significantly higher mean estrogen levels but lower mean progestogen concentrations than did unsuccessful females. Other hormones, including glucocorticoids and androgens, were not significantly different between successful and unsuccessful individuals. Observations of specific behaviors such as unison calling, marching, and the number of copulation attempts, along with overall time spent performing reproductive behaviors, were significantly higher in successful pairs. Our findings indicate that overall reproductive performance of whooping crane pairs is linked to female gonadal hormone excretion and reproductive behaviors, but not to altered adrenal hormone production.

Several authors have suggested that the consumption of plant compounds may have direct effects on wild primate reproductive biology, but no studies have presented physiological evidence of such effects. Here, for two troops of olive baboons (Papio hamadryas anubis) at Gashaka-Gumti National Park, Nigeria, we show major seasonal increases in levels of fecal progesterone metabolites in females, and provide evidence that this is linked to the consumption of natural plant compounds. Increases in fecal progestogen excretion occurred seasonally in all females, in all reproductive states, including lactation. Detailed feeding data on the study animals showed that only one food species is consumed by both troops at the time of observed progestogen peaks, and at no other times of the year: the African black plum, Vitex doniana. Laboratory tests demonstrated the presence of high concentrations of progestogen-like compounds in V. doniana. Together with published findings linking the consumption of a related Vitex species (Vitex agnus castus) to increased progestogen levels in humans, our data suggest that natural consumption of V. doniana was a likely cause of the observed increases in progestogens. Levels of progestogen excretion in the study baboons during periods of V. doniana consumption are higher than those found during pregnancy, and prevent the expression of the sexual swelling, which is associated with ovulatory activity. As consortship and copulatory activity in baboons occur almost exclusively in the presence of a sexual swelling, V. doniana appears to act on cycling females as both a physiological contraceptive (simulating pregnancy in a similar way to some forms of the human contraceptive pill) and a social contraceptive (preventing sexual swelling, thus reducing association and copulation with males). The negative effects of V. doniana on reproduction may be counter-balanced by the wide-range of medicinal properties attributed to plants in this genus. This is

The study investigated, for cycling sheep, synchronizing protocols simultaneously to the standard "P" protocol using progestogens priming with intravaginal devices and gonadotropin. In November 2014, 90 adult Menz ewes were assigned to either the "P" protocol, "PGF" treatment where oestrus and ovulation were synchronized using two injections of prostaglandin 11 days apart or a "GnRH" treatment where the ewes had their oestrus and ovulation synchronized with GnRH (day 0)-prostaglandin (day 6)-GnRH (day 9) sequence. The ewes were naturally mated at the induced oestrus and the following 36 days. Plasma progesterone revealed that 92% of the ewes were ovulating before synchronization and all, except one, ovulated in response to the applied treatments. All "P" ewes exhibited oestrus during the 96-hr period after the end of the treatments in comparison with only 79.3% and 73.3% for "PGF" and "GnRH" ewes, respectively (p sheep after the rainy season when most animals are spontaneously cycling. © 2016 Blackwell Verlag GmbH.

Multimodal Advertisement of Pregnancy in Free-Ranging Female Japanese Macaques (Macaca fuscata.

Directory of Open Access Journals (Sweden)

Lucie Rigaill

Full Text Available The role of multiple sexual signals in indicating the timing of female ovulation, and discrimination of this timing by males, has been particularly well studied among primates. However the exhibition of pregnancy signals, and how such signals might modulate male post-conception mating decisions, is still poorly understood. Here we aimed to determine if Japanese macaque males use changes in female sexual signals (behavioral, visual and auditory to discriminate pregnancy and adjust their socio-sexual behaviors. We combined behavioral observations, digital photography and endocrinological (progestogen and estrogen data, collected systematically during three one-month periods: the pre-conceptive period, the 1st month of pregnancy and the 2nd month of pregnancy. We analyzed variation in the probability of detecting male and female socio-sexual behaviors and estrus calls, as well as changes in female face color parameters, in relation to female reproductive state. Based on our focal observations, we found that males did not copulate during the pregnancy period, and that female socio-sexual behaviors generally decreased from the pre-conceptive to post-conceptive periods. Female face luminance decreased from the pre-conceptive month to the pregnancy period whereas face color only varied between the 1st and 2nd month of gestation. Our results suggest that Japanese macaque females display sexual cues of pregnancy that males might use to reduce energy wasted on non-reproductive copulations with pregnant females. We hypothesize that females advertize their pregnancy through changes in behavioral, visual and potential auditory signals that males can use to adjust their mating behaviors. We finish by discussing implications for male and female post-conception strategies.

Limited knowledge and practice of contraception is a global public health problem. Unintended pregnancies are the primary cause of induced abortion. When safe abortions are not available, as in Nigeria with restricted abortion laws, abortion can contribute significantly to maternal mortality and morbidity. Adequate information on the awareness and the use of emergency contraception is necessary for planning interventions in groups vulnerable to unwanted pregnancy. The aim of the following study is to access the awareness, perception and practice of emergency contraception among female undergraduates in Imo State University, South Eastern Nigeria. A questionnaire based cross-sectional survey using female undergraduates selected randomly from Imo State University, Owerri. A total of 700 students participated in the study. Awareness of emergency contraception was very high (85.1%) (596/700). The awareness was significantly higher amongst students in health related faculties than in the non-health related faculties (P = 0.01). The main sources of information were through friends (43.1%) (317/700) and lectures (22.1%) (192/700). High dose progestogen (postinor-2) was the most commonly known type of emergency contraception (70.8%) (422/596). Only 58.1% (346/596) of those who were aware of emergency contraception approved of their use. The major reasons given by the 41.9% (250/596) who disapproved of their use were religious reasons (50.4%) (126/250) and that they were harmful to health (49.2%) (123/250). Two-third (67%) (46 9/700) of the students were sexually active and only 39.9% (187/469) of them used emergency contraception. High dose progestogen (postinor-2) was again the most commonly used method (70.8%) (422/596). The most common situation in which emergency contraception was used was following unprotected sexual intercourse (45.5%) (85/144). Only 34.6% (206/596) of those who were aware of emergency contraception identified correctly the appropriate time interval

The brown plant hopper (BPH), Nilaparvata lugens Stål (Hemiptera: Delphacidae), is a major pest affecting rice in Asia, and outbreaks of this pest are closely linked to pesticide-induced stimulation of reproduction. Therefore, the BPH is a classic example of a resurgent pest. However, the effects of different genes on the regulation of pesticide-induced reproductive stimulation in the BPH are unclear. In this study, the regulatory effects of acyl-coenzyme A oxidase (ACO) on the reproduction and biochemistry of the BPH were investigated with gene silencing. The number of eggs laid per female by triazophos (TZP)+dsACO BPH females was significantly lower than those of TZP-treated (without ACO silencing) or TZP+GFP females (negative control), with the number of eggs decreasing by 30.8% (from 529.5 to 366.3) and 32.0% (from 540.5 to 366.3), respectively. The preoviposition period, oviposition period, and longevity of the TZP-treated females were also influenced by dsACO treatment. Additionally, the amounts of crude fat, protein, and some fatty acids (oleic acid, palmitic acid, linoleic acid, stearic acid, and myristoleic acid) in TZP+dsACO females were significantly lower than in TZP-treated females. Thus, ACO is one of the key genes regulating the TZP-induced stimulation of reproduction in BPH females. Copyright © 2015 Elsevier Inc. All rights reserved.

Reproductive Health Assessment of Female Elephants in North American Zoos and Association of Husbandry Practices with Reproductive Dysfunction in African Elephants (Loxodonta africana.

Full Text Available As part of a multi-institutional study of zoo elephant welfare, we evaluated female elephants managed by zoos accredited by the Association of Zoos and Aquariums and applied epidemiological methods to determine what factors in the zoo environment are associated with reproductive problems, including ovarian acyclicity and hyperprolactinemia. Bi-weekly blood samples were collected from 95 African (Loxodonta africana and 75 Asian (Elephas maximus (8-55 years of age elephants over a 12-month period for analysis of serum progestogens and prolactin. Females were categorized as normal cycling (regular 13- to 17-week cycles, irregular cycling (cycles longer or shorter than normal or acyclic (baseline progestogens, <0.1 ng/ml throughout, and having Low/Normal (<14 or 18 ng/ml or High (≥14 or 18 ng/ml prolactin for Asian and African elephants, respectively. Rates of normal cycling, acyclicity and irregular cycling were 73.2, 22.5 and 4.2% for Asian, and 48.4, 37.9 and 13.7% for African elephants, respectively, all of which differed between species (P < 0.05. For African elephants, univariate assessment found that social isolation decreased and higher enrichment diversity increased the chance a female would cycle normally.

The Asian elephant data set was not robust enough to support multi-variable analyses of cyclicity status. Additionally, only 3% of Asian elephants were found to be hyperprolactinemic as compared to 28% of Africans, so predictive analyses of prolactin status were conducted on African elephants only.

Full Text Available Objective Our objective was to review the involved mechanisms and propose actions for controlling/treating abnormal uterine bleeding during climacteric hormone therapy. Methods A systemic search of the databases SciELO, MEDLINE, and Pubmed was performed for identifying relevant publications on normal endometrial bleeding, abnormal uterine bleeding, and hormone therapy bleeding. Results Before starting hormone therapy, it is essential to exclude any abnormal organic condition, identify women at higher risk for bleeding, and adapt the regimen to suit eachwoman's characteristics. Abnormal bleeding with progesterone/progestogen only, combined sequential, or combined continuous regimens may be corrected by changing the progestogen, adjusting the progestogen or estrogen/progestogen doses, or even switching the initial regimen to other formulation. Conclusion To diminish the occurrence of abnormal bleeding during hormone therapy (HT, it is important to tailor the regimen to the needs of individual women and identify those with higher risk of bleeding. The use of new agents as adjuvant therapies for decreasing abnormal bleeding in women on HT awaits future studies.

Urethral carcinoma in 2 females has been treated with irradiation together with adjunct chemotherapy. In case 1, a 73-year-old female with squamous cell carcinoma was successfully treated with irradiation of 4,000 rad and peplomycin of 60 mg intravenously given. She has been free from the disease for the past 43 months. In case 2, a 61-year-old female with transitional cell carcinoma was initially treated with irradiation of 5,000 rad together with peplomycin 90 mg, which was followed by another 5,000 rad irradiation. The tumor recurred and the patient was operated on for cystourethrectomy and partial resection of the vagina. A further chemotherapy of cisplatin, peplomycin, and mitomycin C was instituted. She died of the tumor recurrence 23 months after the first visit to our clinic. Diagnosis and treatment modalities on the female urethral carcinoma are briefly discussed. (author)

Ring-X-bearing Drosophila males were irradiated with 0, 1000, 2000 or 3000 R of X-rays and mated to females that had been injected with saline or 10 -4 M TEM. The mortality and the fertility of the treated females were recorded. The rate of dominant lethals, of entire sex chromosome loss and partial loss of the Y chromosome, the sex ratio, and the rate of mosaics were determined on the progeny. TEM slightly increased the rate of mortality of the females. But it did not influence the yield of mutations recovered from the irradiated spermatozoa

Developmental exposure to BPA adversely affects reproductive function. In sheep, prenatal BPA treatment induces reproductive neuroendocrine defects, manifested as LH excess and dampened LH surge and perturbs early ovarian gene expression. In this study we hypothesized that prenatal BPA treatment will also disrupt ovarian follicular dynamics. Pregnant sheep were treated from days 30 to 90 of gestation with 3 different BPA doses (0.05, 0.5, or 5 mg/kg BW/day). All female offspring were estrus synchronized and transrectal ultrasonography was performed daily for 22 days to monitor ovarian follicular and corpora lutea dynamics. Blood samples were collected to assess hormonal preovulatory changes and luteal progesterone dynamics. Statistical analysis revealed that the time interval between the estradiol rise and the preovulatory LH surge was shortened in the BPA-treated females. None of the three BPA doses had an effect on corpora lutea, progestogenic cycles, and mean or duration of ovulatory and non-ovulatory follicles. However, differences in follicular count trajectories were evident in all three follicular size classes (2–3 mm, 4–5 mm, and ≥ 6 mm) of prenatal BPA-treated animals compared to controls. Number of follicular waves tended also to be more variable in the prenatal BPA-treated groups ranging from 2 to 5 follicular waves per cycle, while this was restricted to 3 to 4 waves in control females. These changes in ovarian follicular dynamics coupled with defects in time interval between estradiol rise and preovulatory LH release are likely to lead to subfertility in prenatal BPA-treated females.

Full Text Available CONTEXT AND OBJECTIVE: Urinary incontinence is a public health problem that affects more than 200 million people worldwide. Stress incontinence is the most prevalent type. Pelvic floor muscle exercises have been used for treating it, although there is no consensus regarding their application. The aim of this study was to compare the results from treating female stress urinary incontinence with pelvic floor muscle exercises with or without physiotherapist supervision. DESIGN AND SETTING: This was a randomized, prospective, controlled trial in the Urogynecology and Vaginal Surgery Sector, Universidade Federal de São Paulo. METHODS: Forty-four women were randomized to be treated for stress urinary incontinence with pelvic floor exercises for three consecutive months, into two groups: one with and the other without physiotherapist supervision. They were evaluated before and after treatment using a quality-of-life questionnaire, pad test, micturition diary and subjective evaluation. Descriptive analysis was used to evaluate the population. The homogeneity of the two groups was evaluated using the Kruskal-Wallis and Chi-squared tests. The success of the two groups after treatment was evaluated using the Wilcoxon test. RESULTS: The supervised group showed statistically greater improvement in the pad test, micturition diary and quality of life than did the control group. In the subjective evaluation, only 23.8% of the control group patients were satised with their treatment. In the supervised group, 66.8% of patients did not want any other treatment. CONCLUSION: Supervised pelvic floor muscle exercises presented better results in objective and subjective evaluations than did unsupervised exercises.

Aim: The aim of this study was to investigate left ventricular performance and exercise tolerance in never-treated female hypertensive patients. Materials and Methods: Seventeen female patients with newly established, uncomplicated essential hypertension (aged 25 to 57 years) were evaluated with rest-stress radionuclide gated ventriculography, and were compared to 23 age-matched normotensive female volunteers. Results: Mean blood pressure was significantly higher in patients at rest and during exercise than in controls (121±13 vs. 89±7 mm Hg, and 143±11 vs. 122±9 mm Hg, respectively, p 2 , respectively, p<0.01), while ESV was similar in both groups. Ejection fraction (EF) at rest and stress did not differ significantly (54±10 vs. 55±8%, and 70±10 vs. 66±8%, respectively), but % rise in EF during exercise was significantly higher in patients. At rest and during exercise, there were no significant difference in peak ejection rate (PER) and time to PER (TPER) between patients and controls. Patients had similar peak filling rate (PFR) at rest (2.88±0.79 vs. 2.76±0.76 EDV/s) and during exercise (5.85±1.86 vs. 6.21±1.97 EDV/s), in addition to nonsignificant difference in time to PFR (at rest 143±62 vs. 146±42 ms at rest, and 97±20 vs. 91±19 ms during exercise). Conclusion: Female patients with newly diagnosed, never-treated hypertension have preserved maximal exercise performance, systolic function and diastolic function, but they have significant enlargement of EDV and elevated cardiac output during exercise

Given the tremendous importance of mitochondria to basic cellular functions as well as the critical role of mitochondrial impairment in a vast number of disorders, a compelling question is whether 17β-estradiol (E2) modulates mitochondrial function. To answer this question we exposed isolated liver mitochondria to E2. Three groups of rat females were used: control, ovariectomized and ovariectomized treated with tamoxifen. Tamoxifen has antiestrogenic effects in the breast tissue and is the standard endocrine treatment for women with breast cancer. However, under certain circumstances and in certain tissues, tamoxifen can also exert estrogenic agonist properties. We observed that at basal conditions, ovariectomy and tamoxifen treatment do not induce any statistical alteration in oxidative phosphorylation system and respiratory chain parameters. Furthermore, tamoxifen treatment increases the capacity of mitochondria to accumulate Ca 2+ delaying the opening of the permeability transition pore. The presence of 25 μM E2 impairs respiration and oxidative phosphorylation system these effects being similar in all groups of animals studied. Curiously, E2 protects against lipid peroxidation and increases the production of H 2 O 2 in energized mitochondria of control females. Our results indicate that E2 has in general deleterious effects that lead to mitochondrial impairment. Since mitochondrial dysfunction is a triggering event of cell degeneration and death, the use of exogenous E2 must be carefully considered

To evaluate how physicians in the United States (US) screen for, define, and treat a short cervix to prevent preterm birth. This was a cross-sectional, web-based survey of 500 physicians treating pregnant patients with a short cervix in the US. Respondents' geographic region was monitored to ensure balance across the nine US Census divisions. Respondents were predominantly obstetrician/gynecologists (86%, 429/500; mean age 49 years). Physicians reported that a median of 90% of their pregnant patients undergo cervical length screening; 81% (407/500) use transvaginal ultrasound. Physicians consult multiple evidence sources to inform their patient care, most commonly clinical guidelines (83%; 413/500) and published research (70%; 349/500). Most physicians (98%; 490/500) reported treating pregnant patients with a short cervix; 95% (474/500) use synthetic and/or natural progestogen, alone or in combination with other treatment modalities. If reimbursement was not a concern, 47% of physicians (230/500) would choose vaginal progesterone as their preferred treatment to prevent preterm birth in all patients with a short cervix, and 45% (218/500) would choose a synthetic progestogen. US guidelines recommend transvaginal ultrasound for cervical length screening; 81% of physicians in this study reported using this method. Most physicians surveyed use progestogens to treat a short cervix, with approximately half choosing a synthetic progestin (45%) and half choosing natural progesterone (47%) as their preferred treatment, despite national guidelines recommending only vaginal natural progesterone for this indication. Additional physician education is required to implement current and best practices.

Lammert, Marge; Mautner, Victor-Felix; Kluwe, Lan

2005-01-01

Neurofibromas are benign tumors of the peripheral nerves and hallmark of neurofibromatosis type 1 (NF1), a tumor suppressor gene syndrome. Neurofibromas mostly start developing at puberty and can increase in size and number during pregnancy. Expression of progesterone receptors has been found in 75% of the tumors. Many female NF1 patients are thus concerned about the possibility that hormonal contraceptives may stimulate the growth of their neurofibromas. A survey was carried out on 59 female NF1 patients who are practicing or have practiced hormonal contraception to examine the effect of the various contraceptives on the growth of neurofibromas. Majority (53 out of 58) of patients who received oral estrogen-progestogen or pure progestogen preparations reported no associated tumor growth. In contrast, significant tumor growth was reported by two patients who received depot contraceptive containing high dose of synthetic progesterone. Oral contraceptives do not seem to stimulate the growth of neurofibromas in NF1 patients. High doses of progesterone might stimulate the growth of neurofibromas and deserve more caution

Meningioma growth has been previously described in patients receiving oestrogen/progestogen therapy. We describe the clinical, radiological, biochemical and pathologic findings in a 45-year-old woman with congenital adrenal hyperplasia secondary to a defect in the 21-hydroxylase enzyme who had chronic poor adherence to glucocorticoid therapy with consequent virilisation. The patient presented with a frontal headache and marked right-sided proptosis. Laboratory findings demonstrated androgen excess with a testosterone of 18.1 nmol/L (0-1.5 nmol) and 17-Hydroxyprogesterone >180 nmol/L (transsexual patients undergoing therapy with high-dose oestrogen and progestogens. Progesterone receptor positivity has been described previously in meningiomas. 17-Hydroxyprogesterone is elevated in CAH and has affinity and biological activity at the progesterone receptor. Therefore, we hypothesise that patients who have long-standing increased adrenal androgen precursor concentrations may be at risk of meningioma growth. Patients with long-standing CAH (particularly if not optimally controlled) may present with other complications, which may be related to long-standing elevated androgen or decreased glucocorticoid levels.Chronic poor control of CAH is associated with adrenal myelolipoma and adrenal rest tissue tumours.Meningiomas are sensitive to endocrine stimuli including progesterone, oestrogen and androgens as they express the relevant receptors.

EFFICACY OF PELVIC FLOOR THERAPY IN TREATING URINARY INCONTINENCE AMONG FEMALE COPD PATIENTS

Full Text Available Background: Chronic obstructive pulmonary disease (COPD is a leading cause of morbidity and mortality worldwide. The major manifestation of COPD includes dyspnea, decreased oxygenation and reduced exercise tolerance. The other manifestations such as urinary incontinence are less noted and treated inadequately. The prevalence of urinary incontinence in Indian COPD population has not been well documented. The treatment of urinary incontinence includes pelvic floor exercises (Kegel’s exercises, biofeedback, and acupuncture etc. Methods: Forty female moderate COPD patients diagnosed according to American Thoracic Criteria with a complaint of urinary incontinence were selected for the study. Pelvic floor therapy exercises were given daily 5 sets per day (1 set =1-3 counts for seven days. Baseline evaluation was done using International Consultation on Incontinence Short Form (ICIQ-SF on the day of referral for physiotherapy and the post study measurements were taken on 7th day of hospital stay. Wilcoxon Signed Rank calculator was used to assess the data collected. Results: The z value of ICIQ-SF questionnaire was 5.5109 ( p≤ 0.05 based on Wilcoxon Sign rank test and it was significant when we compared the pre and post test mean difference. The pre test mean score of ICIQ-SF was 14.175 and post test mean score was 4.4.Based on the findings, the results showed significant improvement in patient symptoms and reduced stress incontinence post pelvic floor therapy exercises. Conclusion: The study emphasizes the importance of pelvic floor therapy in treating stress urinary incontinence among COPD patients and it should also be included in a comprehensive pulmonary rehabilitation program.

Creatine is an antioxidant, neuromodulator and key regulator of energy metabolism shown to improve depressive symptoms in humans and animals, especially in females. To better understand the pharmacological effects of creatine, we examined its influence on depression-related hippocampal gene expression and behaviors in the presence and absence of sex steroids. Sham-operated and gonadectomized male and female rats were fed chow alone or chow blended with either 2% or 4% w/w creatine monohydrate for five weeks before forced swim, open field, and wire suspension tests, or seven weeks total. Before supplementation, males were chronically implanted with an empty or a testosterone-filled (T) capsule (10-mm surface release), and females were administered progesterone (P, 250 μg), estradiol benzoate (EB, 2.5 μg), EB+P, or sesame oil vehicle weekly. Relative to non-supplemented shams, all hippocampal plasticity-related mRNAs measured, including brain-derived neurotrophic factor (BDNF), tyrosine kinase B, doublecortin, calretinin, and calbindin, were downregulated in sham males given 4% creatine, and BDNF, doublecortin, and calbindin mRNAs were downregulated in sham females given 4% creatine. In contrast, combined 4% creatine+T in castrates prevented downregulation of BDNF, doublecortin, and calretinin mRNAs. Similarly, combined 4% creatine+EB+P in ovariectomized females attenuated downregulation of BDNF and calbindin mRNA levels. Moderate antidepressant and anxiolytic-like behaviors were observed in EB+P-treated ovariectomized females fed creatine, with similar trends in T-treated castrates fed creatine. Altogether, these data show that chronic, high-dose creatine has opposing effects on neuroplasticity-related genes and depressive behavior in intact and gonadectomized male and female rats. The dose and schedule of creatine used negatively impacted hippocampal neuronal integrity in otherwise healthy brains, possibly through negative compensatory changes in energy

The Bracing in Adolescent Idiopathic Scoliosis Trial (BrAIST) included skeletally immature high-risk patients with adolescent idiopathic scoliosis (AIS) with moderate curve sizes (20°- 40°). BrAIST was a multicenter, controlled trial using both randomized and preference treatment arms into either an observation group or a brace treatment group. The aim of this study was to analyze and compare body image and quality-of-life (QOL) in female AIS patients who were observed or treated with a brace. Brace treatment is an effective means for controlling progressive scoliosis and preventing the need for surgery, but there is no consensus regarding the effect of brace treatment on body image or on QOL in adolescents with AIS. Data from female BrAIST patients in the randomized (n = 132) or preference (n = 187) arms and were observed (n = 120) or brace treated (n = 199) were analyzed. Patients completed the Spinal Appearance Questionnaire (SAQ) and the Pediatric Quality of Life Inventory (PedsQOL) 4.0 Generic Scales at baseline and 6 month follow-up visits up to 2 years. Items on the SAQ measured three body image constructs (self, ideal, and overall). The PedsQOL measured health, activities, feelings, social factors, and school. . In general, there were no significant differences within or between study arms or treatments regarding body image or QOL through 2 years of follow-up. Poorer body image was significantly correlated with poorer QOL during the first 2 years of follow-up regardless of study arm or treatment. Patients who crossed-over to a different treatment and patients with largest Cobb angles ≥ 40 degrees had significantly poorer body image, in particular self-body image, compared with those that did not. This study does not support findings from previous research indicating that wearing a brace has a negative impact on or is negatively impacted by body image or QOL. 2.

Scoliosis is a disorder that leads to dysfunction of a number of systems in the body, especially in young females. Physical capacity is one of the most important elements of good health as well as ofbiological development. Adolescence is a time when physical capacity develops intensively, and the condition of the respiratory system is one of many factors that have an impact on the level of physical capacity. This paper aims to evaluate a short-term application of two methods of physiotherapy and their influence on the level of exercise tolerance in young females suffering from idiopathic scoliosis. The study involved a group of 49 young females aged 14-15 years diagnosed with (2040°) thoracic and lumbar scoliosis who were in-patients at the rehabilitation ward of the Regional Paediatric Rehabilitation Hospital in Jastrzębie Zdrój. The group was divided into two subgroups depending on the method of rehabilitation employed: the first subgroup received asymmetric breathing exercise therapy by Dobosiewicz and the second subgroup practised symmetric remedial exercises. Cobb's angle, the degree of skeletal maturity, i.e. the Risser sign and the degree trunk rotation of the apex of the curvature by means of Raimondi's coefficient were determined once in an x-ray image. Basic somatic features, maximal voluntary ventilation (MVV parameter), selected motor skills and exercise tolerance were assessed on two occasions (before beginning and after completion of the rehabilitation treatment). 1. Young females suffering from (20-40°) thoracic and lumbar scoliosis demonstrate respiratory dysfunction, as shown by decreased maximal voluntary ventilation (MVV) in the two subgroups in the present study. Exercises according to Dobosiewicz's method brought about a significantly higher degree of improvement in this parameter. 2. The physiotherapeutic regimen administered to the young girls with scoliosis significantly improved their strength motor skills and exercise tolerance. A

Body composition changes cannot be precisely captured using body weight or body mass index measures. Therefore, the primary purpose of this review was to characterize the patterns of body composition change in females treated for breast cancer including only studies that utilize imaging technologies to quantify adipose tissue and lean body mass (LBM). We reviewed PubMed for studies published between 1971 and 2012 involving females diagnosed with breast cancer where computed axial tomography , dual-energy X-ray absorptiometry, or magnetic resonance imaging were employed for body composition assessment. Of the initial 440 studies, 106 papers were evaluated and 36 papers met all eligibility criteria (15 observational and 21 intervention trials). Results of these studies revealed that body weight did not consistently increase. Importantly, studies also showed that body weight did not accurately depict changes in lean or adipose tissues. Further findings included that sarcopenic obesity as a consequence of breast cancer treatment was not definitive, as menopausal status may be a substantial moderator of body composition. Overall, the behavioral interventions did not exhibit consistent or profound effects on body composition outcomes; approximately half showed favorable influence on adiposity while the effects on LBM were not apparent. The use of tamoxifen had a clear negative impact on body composition. The majority of studies were conducted in predominantly white survivors, highlighting the need for trials in minority populations. Collectively, these studies were limited by age, race, and/or menopause status matched control groups, overall size, and statistical power. Very few studies simultaneously collected diet and exercise data-two potential factors that impact body composition. Future breast cancer trials should prioritize precise body composition methodologies to elucidate how these changes impact recurrence, prognosis, and mortality, and to provide clinicians

Dr. De Teresa and others reported that mean prothrombin time ratio of 12 patients on long-term anticoagulation with warfarin was significantly higher when they were also taking oral contraceptives (OCs). A study of prothrombin complex activity was recently conducted in female rats treated with an estrogen-progestogen combination (lynestrenol 5 mg; mestranol 0.3 mg/kg body weight) which resulted in a 100% infertility in this species. After 1 treatment for only 1 estral cycle, OC-treated rats had a significantly longer Normotest clotting time (37.7+ or-0.5 sec) than control rats (31.0+or-0.4); the difference was even more notable after 10 cycles. Although this finding has not been reported in women on OCs, it may be that the estrogen-induced "lability" of the prothrombin complex occurs in humans only in special conditions, such as anticoagulation. Alternatively, liver dysfunction occurring among women on OCs may be responsible for reduced metabolism of warfarin, contributing to the effectiveness of the anticoagulation. Further pharmacology studies should be done to clarify the interaction between OCs and oral anticoagulants.

Full Text Available AbstractBackground: Endometriosis is a common gynecological problem associated with chronic pelvic pain. Objective: To evaluate the effectiveness of current hormonal treatments of endometriosis associated pain.Materials and Methods: Randomized Controlled studies identified from databases of Medline and Cochrane Systemic Review groups were pooled. 7 RCTs were recruited for evaluation in this review. Data from these studies were pooled and meta-analysis was performed in three comparison groups: 1 Progestogen versus GnRHa; 2 Implanon versus Progestogen (injection; 3 Combined oral contraceptive pills versus placebo and progestogen. Response to treatment was measured as a reduction in pain score. Pain improvement was defined as improvement ≥1 at the end of treatment. Results: There was no significant difference between treatment groups of progestogen and GnRHa (RR: 0.036; CI:-0.030-0.102 for relieving endometriosis associated pelvic pain. Long acting progestogen (Implanon and Mirena are not inferior to GnRHa and depot medroxy progesterone acetate (DMPA (RR: 0.006; CI:-0.142-0.162. Combined oral contraceptive pills demonstrated effective treatment of relieving endometriosis associated pelvic pain when compared with placebo groups (RR:0.321CI-0.066-0.707. Progestogen was more effective than combined oral contraceptive pills in controlling dysmenorrhea (RR:-0.160; CI:-0.386-0.066, however, progestogen is associated with more side effects like spotting and bloating than the combined contraceptive pills. Conclusion: Combined oral contraceptive pills (COCP, GnRHa and progestogens are equally effective in relieving endometriosis associated pelvic pain. COCP and progestogens are relatively cheap and more suitable for long-term use as compared to GnRHa. Long-term RCT of medicated contraceptive devices like Mirena and Implanon are required to evaluate their long-term effects on relieving the endometriosis associated pelvic pain

Photobiomodulation, also referred to as low-level laser therapy (LLLT), has been studied and used for (among other diseases) the promotion of hair regrowth. A clinical study was developed to define the physiologic effects that occur when the human hair follicle and surrounding tissue structures are exposed to laser light using a novel device that is fitted with an array of laser diode sources operating at 650 nm and placed inside a sports cap to promote discretion while in use. The study demonstrates that low-level laser treatment of the scalp every other day for 17 weeks using the HANDI-DOME LASER device is a safe and effective treatment for androgenetic alopecia in healthy females between the ages of 18 to 60 with Fitzpatrick skin Types I to IV and Ludwig-Savin Baldness Scale I-2 to II-2 baldness patterns. Subjects receiving LLLT at 650 nm achieved a 51% increase in hair counts as compared with sham-treated control patients in this multicenter randomized controlled trial. These results suggest that the emerging technology of low-level laser therapy may play a potentially significant role in health care providers' armamentarium for the disease androgenic alopecia.

In the presented study, we aimed to assess changes over time in the perception of trunk deformity, body function, stress level and mental health in females with adolescent idiopathic scoliosis (AIS) who were treated conservatively with a Cheneau brace, taking the Trunk Appearance Perception Scale (TAPS), Scoliosis Research Society-22 (SRS-22) and Bad Sobberheim Stress Questionnaires (BSSQ) criteria of evaluation into consideration. The study design was comprised of three questionnaire assessments, with the second and the third evaluation taking place 6 and 12 months after the beginning of the study, respectively. Thirty-six females treated conservatively were asked to fill in the TAPS, SRS-22 and BSSQ forms. In regards to TAPS, the results differed between the 1st and the 2nd assessment in Figure 2 only (p = 0.013). The difference between the 1st and the 3rd evaluation concerned Figure 3 and the total score (p = 0.011 and p = 0.005, respectively). The SRS-22 and BSSQ results of study participants did not differ significantly between the 1st and the 2nd, between the 2nd and the 3rd and between the 1st and the 3rd evaluations. The study indicated that the assessment of girls with AIS concerning body function and mental health did not deteriorate in the course of orthosis treatment. Furthermore, they showed improvement in perceptions particularly in regards to trunk shape. We pointed out that the negative perceptions of mental health, self-image and low level of activity held by females with AIS coexisted with severe emotional distress. Moreover, factors that improved functioning or subjective physical appearance ratings in particular, such as level of activity, were indicated.

Anabolic-androgenic steroids are misused, including by women, but little is known about the cardiovascular effects of these drugs on women. To evaluated the effects of nandrolone decanoate (ND) and resistive physical exercise on cardiac contractility in young female rats. Female Wistar rats were separated into 4 groups: C (untrained animals); E (animals were submitted to resistance exercise by jumping in water 5 times per week); ND (animals were treated with ND, 20mg/kg/week for 4weeks); and NDE (trained and treated). The haemodynamic parameters (+dP/dtmax, -dP/dtmin and Tau) were assessed in the left ventricle. The heart was collected for histological analyses and collagen deposition. The gastrocnemius muscle was weighed, and hypertrophy was assessed by the ratio of their weights to gastrocnemius/tibia length. The expression of calcium handling proteins was measured by western blot analysis. ND treatment and physical exercise increased cardiac contractility and relaxation. In addition, ND promoted increases in phospholamban phosphorylated (p-PLB) and isoforms of sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA2a) expression, while resistance exercise increased the phosphorylation of PLB and expression of Na(+)/Ca(2+) exchangers (NCX). Cardiac hypertrophy and collagen deposition were observed after ND treatment. Regulatory components of cytosolic calcium, such as SERCA2a and p-PLB, play important roles in modulating the contractility and relaxation effects of ND in females. Copyright © 2016 Elsevier Inc.

To clarify the direct effects of androgens, the changes in the hypothalamic levels of reproductive and appetite regulatory factors induced by chronic dihydrotestosterone (DHT) administration were evaluated in female rats. DHT treatment increased the BW and food intake of the ovariectomized rats, but not the estradiol (E2)-treated rats. DHT administration suppressed the expression of a hypothalamic anorexigenic factor. Although the kisspeptin (Kiss1) mRNA levels of the anterior hypothalamic block (the anteroventral periventricular nucleus, AVPV) were increased in the E2-treated rats, DHT administration did not affect the Kiss1 mRNA levels of the AVPV in the ovariectomized or E2-treated rats. Conversely, DHT administration reduced the Kiss1 mRNA levels of the posterior hypothalamic block (the arcuate nucleus, ARC) in the ovariectomized rats. Although the Kiss1 mRNA levels of the posterior hypothalamic block (ARC) were decreased in the E2-treated rats, DHT administration did not affect the Kiss1 mRNA levels of the ARC in these rats. Serum luteinizing hormone levels of these groups exhibited similar patterns to the Kiss1 mRNA levels of the ARC. These results showed that DHT affects the production of hypothalamic reproductive and appetite regulatory factors, and that these effects of DHT differ according to the estrogen milieu.

Background Primary spontaneous pneumothorax (PSP) is treated based on studies that have predominantly consisted of tall male subjects. Here we determined recurrence of PSP in average-statured menstruating women and studied prevalence of catamenial pneumothorax (CP) in this population. Methods Males and menstruating females, aged 18-55 years, without underlying lung disease or substance abuse were retrospectively studied between 2009-2015. A chest pathologist reviewed all specimens for thoracic endometriosis. Kaplan-Meier curves were constructed to determine recurrence. Results The median age of females (n=33) and males (n=183) was 33.4 and 31.6 years, respectively. In females, nine (27%) had left-sided and 24 (73%) had right-sided PSP, treated with tube thoracostomy. Recurrence occurred in 21 (64%) females with median follow up of 14 months and was treated with thoracoscopic pleurodesis. Right PSP had higher recurrence (70%) compared to left (56%, p=0.02). Four females (12%) presented with recurrent tension pneumothorax within six months. Eight (24%) patients had PSP within 72 hours of menses, meeting clinical criteria of CP. All these were placed on hormonal suppression after initial episode but went on to develop recurrence that was treated with pleurodesis. However, classic endometrial glands were not found in any biopsy specimens obtained during the thoracoscopy. In contrast to female subjects, only 8 (4.4%) average-statured males had recurrence (p<0.001) with a median follow up of 16 months. Conclusions PSP in healthy average-statured menstruating women has high recurrence compared to male counterparts. CP is a clinical diagnosis and often recurs despite hormonal suppression therapy.

Medroxyprogesterone acetate (MPA), a progestin-based hormonal contraceptive designed to mimic progesterone, has been linked to increased human immunodeficiency virus (HIV-1) susceptibility. Genital epithelial cells (GECs) form the mucosal lining of the female genital tract (FGT) and provide the first line of protection against HIV-1. The impact of endogenous sex hormones or MPA on the gene expression profile of GECs has not been comprehensively documented. Using microarray analysis, we characterized the transcriptional profile of primary endometrial epithelial cells grown in physiological levels of E2, P4, and MPA. Each hormone treatment altered the gene expression profile of GECs in a unique manner. Interestingly, although MPA is a progestogen, the gene expression profile induced by it was distinct from P4. MPA increased gene expression of genes related to inflammation and cholesterol synthesis linked to innate immunity and HIV-1 susceptibility. The analysis of gene expression profiles provides insights into the effects of sex hormones and MPA on GECs and allows us to posit possible mechanisms of the MPA-mediated increase in HIV-1 acquisition. © 2017 John Wiley & Sons A/S.

Full Text Available The GLUT4 transporter plays a key role in insulin-induced glucose uptake, which is impaired in insulin resistance. The objective of the present study was to investigate the tissue content and the subcellular distribution of GLUT4 protein in 4- to 12-year-old control, obese and insulin-treated diabetic mongrel female dogs (4 animals per group. The parametrial white adipose tissue was sampled and processed to obtain both plasma membrane and microsome subcellular fractions for GLUT4 analysis by Western blotting. There was no significant difference in glycemia and insulinemia between control and obese animals. Diabetic dogs showed hyperglycemia (369.9 ± 89.9 mg/dl. Compared to control, the plasma membrane GLUT4, reported per g tissue, was reduced by 55% (P < 0.01 in obese dogs, and increased by 30% (P < 0.05 in diabetic dogs, and the microsomal GLUT4 was increased by ~45% (P < 0.001 in both obese and diabetic animals. Considering the sum of GLUT4 measured in plasma membrane and microsome as total cellular GLUT4, percent GLUT4 present in plasma membrane was reduced by ~65% (P < 0.001 in obese compared to control and diabetic animals. Since insulin stimulates GLUT4 translocation to the plasma membrane, percent GLUT4 in plasma membrane was divided by the insulinemia at the time of tissue removal and was found to be reduced by 75% (P < 0.01 in obese compared to control dogs. We conclude that the insulin-stimulated translocation of GLUT4 to the cell surface is reduced in obese female dogs. This probably contributes to insulin resistance, which plays an important role in glucose homeostasis in dogs.

Prenatal testosterone (T) excess in sheep leads to peripheral insulin resistance (IR), reduced adipocyte size, and tissue-specific changes, with liver and muscle but not adipose tissue being insulin resistant. To determine the basis for the tissue-specific differences in insulin sensitivity, we assessed changes in negative (inflammation, oxidative stress, and lipotoxicity) and positive mediators (adiponectin and antioxidants) of insulin sensitivity in the liver, muscle, and adipose tissues of control and prenatal T-treated sheep. Because T excess leads to maternal hyperinsulinemia, fetal hyperandrogenism, and functional hyperandrogenism and IR in their female offspring, prenatal and postnatal interventions with antiandrogen, flutamide, and the insulin sensitizer rosiglitazone were used to parse out the contribution of androgenic and metabolic pathways in programming and maintaining these defects. Results showed that (1) peripheral IR in prenatal T-treated female sheep is related to increases in triglycerides and 3-nitrotyrosine, which appear to override the increase in high-molecular-weight adiponectin; (2) liver IR is a function of the increase in oxidative stress (3-nitrotyrosine) and lipotoxicity; (3) muscle IR is related to lipotoxicity; and (4) the insulin-sensitive status of visceral adipose tissue appears to be a function of the increase in antioxidants that likely overrides the increase in proinflammatory cytokines, macrophages, and oxidative stress. Prenatal and postnatal intervention with either antiandrogen or insulin sensitizer had partial effects in preventing or ameliorating the prenatal T-induced changes in mediators of insulin sensitivity, suggesting that both pathways are critical for the programming and maintenance of the prenatal T-induced changes and point to potential involvement of estrogenic pathways.

We previously showed that estradiol can have both defeminizing and feminizing effects on the developing mouse brain. Pre- and early postnatal estradiol defeminized the ability to show lordosis in adulthood, whereas prepubertal estradiol feminized this ability. Furthermore, we found that estradiol upregulates progesterone receptors (PR) during development, inducing both a male-and female-typical pattern of PR expression in the mouse hypothalamus. In the present study, we took advantage of a newly developed PR antagonist (ZK 137316) to determine whether PR contributes to either male- or female-typical sexual differentiation. Thus groups of male and female C57Bl/6j mice were treated with ZK 137316 or OIL as control: males were treated neonatally (P0-P10), during the critical period for male sexual differentiation, and females were treated prepubertally (P15-P25), during the critical period for female sexual differentiation. In adulthood, mice were tested for sexual behavior. In males, some minor effects of neonatal ZK treatment on sexual behavior were observed: latencies to the first mount, intromission and ejaculation were decreased in neonatally ZK treated males; however, this effect disappeared by the second mating test. By contrast, female mice treated with ZK during the prepubertal period showed significantly less lordosis than OIL-treated females. Mate preferences were not affected in either males or females treated with ZK during development. Taken together, these results suggest a role for PR and thus perhaps progesterone in the development of lordosis behavior in female mice. By contrast, no obvious role for PR can be discerned in the development of male sexual behavior. Copyright © 2016 Elsevier Inc. All rights reserved.

Synchronized oestrous was induced in indigenous Damascus goats, outside the breeding season, using intravaginal progestogen sponges containing 60 mg of medroxyprogesterone acetate (MAP), plus pregnant mare serum gonadotrophin (PMSG). A total of 78 female Damascus goats of mixed ages (1.5 to 5 years) were divided randomly into 2 equal groups, T and C. The females in Group T were treated with MAP for 18 days and injected intramuscularly with either 150 of 200 IU PMSG at sponge withdrawal, whereas, animals in Group C (control) received no treatment. The results indicated that oestrous was induced between 21 to 68 h post-sponge withdrawal in all treated animals, resulting in oestrous response of 100%. all animals in Group C were in anoestrous during the treatment period. In the Group T, conception rate and fecundity rate were 65.8% and 195.2%, respectively. There was no significant difference in pregnancy duration between animals carrying singles and twins (149 versus 184.5 days, respectively). The average birth weight of kids was 3.8 kg. However, single-born kids were significantly (p < 0.05) heavier at birth than individual twins (4.8 versus 3.8 kg). The results suggest that it is possible to induce synchronized and fertile oestrous, obtain successful pregnancy and kidding in Damascus goats outside the breeding season, using intravaginal sponges and successful.

Cardiac hypertrophy and collagen deposition were observed after ND treatment. Conclusion: Regulatory components of cytosolic calcium, such as SERCA2a and p-PLB, play important roles in modulating the contractility and relaxation effects of ND in females. - Highlights: • ND and resistive exercise enhanced the cardiac function and increased expression of cytosolic calcium regulatory components.

Full Text Available Diabetes is a metabolic disorder which affects whole body systems including reproductive system. Diabetes is also a contributing factor to infertility. Metformin is one of the most common drugs to control hyperglycemia. In this study, 36 adult Sprague-Dawley female rats (170-210 g were divided into 3 groups (control, diabetic and diabetic-treated by metformin. In second and third groups, diabetes was induced by streptozotocin injection (45 mg kg-1, IP and the third group was treated by metformin hydrochloride (100 mg kg-1 day-1, PO for 8 weeks. Body weights were compared and blood glucose, gonadotropins and sexual hormones were measured. In diabetic group the blood glucose level significantly (P < 0.05 increased in comparison with that of control and metformin-treated diabetic rats. The results also revealed that, in the untreated diabetic rats, the mean body weights and pituitary-gonadal axis hormones were significantly (P < 0.05 reduced in comparison with the control. Although there were significant (P < 0.05 reduction in mean body weights in metformin-treated diabetic rats, reduction in pituitary-gonadal axis hormones was not as sharp as in untreated diabetic rats and only level of progesterone was significantly (P < 0.05 reduced in comparison with the control. The results of this investigation revealed that there was a clear relationship between experimental diabetes with body weight and pituitary-gonadal axis hormones, and treatment with metformin relatively restored diabetic complications.

Aqueous exposure to the progestin, levonorgestrel, alters anal fin development and reproductive behavior in the eastern mosquitofish (Gambusia holbrooki)

Frankel, Tyler E.; Meyer, Michael T.; Orlando, Edward F.

Endogenous progestogens are important regulators of vertebrate reproduction. Synthetic progestins are components of human contraceptive and hormone replacement pharmaceuticals. Both progestogens and progestins enter the environment through a number of sources, and have been shown to cause profound effects on reproductive health in various aquatic vertebrates. Progestins are designed to bind human progesterone receptors, but they also have been shown to strongly activate androgen receptors in fish. Levonorgestrel (LNG) activates fish androgen receptors and induces development of male secondary sex characteristics in females of other species. Although behavior has been postulated to be a sensitive early indicator of exposure to certain environmental contaminants, no such research on the reproductive behavior of gestagen-exposed fish has been conducted to date. The goal of our study was to examine the exposure effects of a human contraceptive progestin, LNG, on the reproductive development and behavior of the viviparous eastern mosquitofish (Gambusia holbrooki). Internal fertilization is a requisite characteristic of viviparous species, and is enabled by an androgen driven elongation of the anal fin into the male gonopodium (i.e., phallus). In this study, we exposed adult mosquitofish to ethanol (EtOH control), 10 ng/L, and 100 ng/L LNG for 8 d using a static replacement exposure design. After 8 d, a subset of males and females from each treatment were examined for differences in the 4:6 anal fin ratio. In addition, paired social interaction trials were performed using individual control males and control females or females treated 10 ng/L or 100 ng/L LNG. Female mosquitofish exposed to LNG were masculinized as evidenced by the elongation of the anal fin rays, a feature normal to males and abnormal to females. LNG caused significant increases in the 4:6 anal fin ratios of female mosquitofish in both the 10 ng/L and 100 ng/L treatments, although these

Marmosets treated with oxytocin are more socially attractive to their long-term mate

Full Text Available Adult male-female bonds are partly characterized by initiating and maintaining close proximity with a social partner, as well as engaging in high levels of affiliative and sociosexual behavior. Oxytocin (OXT, a neuromodulatory nonapeptide, plays a critical role in the facilitation of social bonding and prosocial behavior toward a social partner (Feldman, 2012. However, less attention has been given to whether augmentation of OXT levels in an individual alters others’ perceptions and behavior toward an OXT-treated social partner. We examined social dynamics in well-established male-female pairs of marmoset monkeys (Callithrix jacchus in which one member of the pair was administered an intranasal OXT agonist, an OXT antagonist, or saline. OXT treatment did not alter the expression of affiliative toward an untreated partner. However, OXT did significantly influence the expression of proximity and grooming behavior with a treated partner, as a function of OXT treatment and sex. Female interest in initiating and maintaining proximity with a pair-mate was altered by OXT treatment. Untreated female marmosets departed from their saline-treated partner more frequently than they approached them, as indicated by a low proximity index score. However, when males received an intranasal OXT agonist they had a significantly increased proximity index score relative to saline, indicating that their untreated partner approached them more often than they departed from them. Saline-treated females initiated and received equivalent levels of grooming behavior. However, when female marmosets were treated with an OXT agonist their untreated partner groomed them proportionately more often, for a greater total duration, and for more time per bout, than they initiated grooming behavior. These results suggest that intranasal OXT altered male and female marmosets’ stimulus properties in such a way as to increase the amount of grooming behavior that females received from

Recent advances in female sexual dysfunction.

Female sexuality has received little scientific study. Recently, increased interest in this field has generated new research in the epidemiology, pathophysiology, and pharmacotherapy of female sexual dysfunction (FSD). A new FSD classification system has been proposed. Although sexual difficulties are highly prevalent among women, the degree of associated distress is unknown. Risk factors for FSD are probably both psychologic and physiologic. Aging or menopause is associated with lubrication difficulties, which can be treated with hormone replacement. Hysterectomy seems more likely to result in improvement rather then deterioration of sexual functioning. Depression may be a predictor of sexual dysfunction after hysterectomy. Vasoactive agents are currently being evaluated as treatment for female sexual arousal disorder. The most important advance in the study of female sexual function is the recent surge of interest in this relatively unexplored field.

Full Text Available This study aimed to analyze ovary histology and quantify total protein in the hemolymph of Rhipicephalus (Boophilusmicroplus females treated with hexane extracts from green fruits of Melia azedarach. Eight engorged females were immersed in the extract at 0.25% concentration, and eight in water containing 5% acetone (control. The females were dissected 72 hours after treatment, and the ovaries were weighed and subjected to standard histological techniques. The total protein concentration was measured in the hemolymph of 200 females, of which 100 were treated as described above and 100 served as a control. In the treated group, ovary weight reduction and predominance of immature oocytes were observed. In addition, there were decreases in the diameters of the cytoplasm and germ vesicle of the oocytes in the treated group, compared with the controls. The protein concentration in the hemolymph was higher in the treated group than in the controls. The morphological changes observed in the treated ovaries included: presence of vacuolization; alteration of oocyte morphology, which changed from rounded to elongated; deformation of the chorion; and disorganization of the yolk granules. These results demonstrate the action ofM. azedarach fruit extracts on R.(B. microplus oogenesis.

Pregnant female mice were injected (ip) with 20 μCi of 35 S or 0.5 ml of saline (control) on 3.5 day of gestation. The animals were allowed to litter and the (CBA female x C 3 H/He male) F 1 males treated as embryos were tested at maturity (8-10 weeks) for dominant lethal incidence. Each male was mated to 3 untreated virgin females for a period of 3 weeks. The pregnant animals were killed at mid gestation and the uterine contents and corpora lutea were examined. There was a significant increase in the frequency of dominant lethals both at pre- and post-implantation stages in the treated group when compared to controls. As a result a significant increase in dead implantations/female and reduction in live implantations/female were noticed in the treated group. Thus the results clearly delineate the genetic effects of sulfur-35 in mice. (auth.)

Anabolic-androgenic steroids are misused, including by women, but little is known about the cardiovascular effects of these drugs on women. Aim: To evaluated the effects of nandrolone decanoate (ND) and resistive physical exercise on cardiac contractility in young female rats. Main methods: Female Wistar rats were separated into 4 groups: C (untrained animals); E (animals were submitted to resistance exercise by jumping in water 5 times per week); ND (animals were treated with ND, 20 mg/kg/week for 4 weeks); and NDE (trained and treated). The haemodynamic parameters (+ dP/dt{sub max}, − dP/dt{sub min} and Tau) were assessed in the left ventricle. The heart was collected for histological analyses and collagen deposition. The gastrocnemius muscle was weighed, and hypertrophy was assessed by the ratio of their weights to gastrocnemius/tibia length. The expression of calcium handling proteins was measured by western blot analysis. Results: ND treatment and physical exercise increased cardiac contractility and relaxation. In addition, ND promoted increases in phospholamban phosphorylated (p-PLB) and isoforms of sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA2a) expression, while resistance exercise increased the phosphorylation of PLB and expression of Na{sup +}/Ca{sup 2+} exchangers (NCX). Cardiac hypertrophy and collagen deposition were observed after ND treatment. Conclusion: Regulatory components of cytosolic calcium, such as SERCA2a and p-PLB, play important roles in modulating the contractility and relaxation effects of ND in females. - Highlights: • ND and resistive exercise enhanced the cardiac function and increased expression of cytosolic calcium regulatory components.

Female genital mutilation (FGM) is a violation of human rights; yet, more than 100 million females are estimated to have undergone the procedure worldwide. There is an increased need for physician education in treating FGM. Female pelvic surgeons have a unique opportunity to treat this population of patients. Here, we depict the classification of FGM and a general approach to FGM reversal. We specifically address the procedure of type III FGM reversal, or defibulation. In this video, we first highlight the importance of the problem of FGM. Next, we present the classification of FGM using an original, simple, schematic diagram highlighting they key anatomic structures involved in the four types of FGM. We then present a simple case of reversal of type III FGM, a procedure also known as defibulation. After depicting the surgical procedure, we discuss clinical results and summarize key principles of the defibulation procedure. Our patient was a 25-year-old woman who had undergone type III FGM as a child in Somalia. She desired restoration of vaginal function. We performed a reversal, and her postoperative course was uncomplicated. By 6 weeks postoperatively, she was able to engage in sexual intercourse without dyspareunia. FGM is a problem at the doorsteps of female pelvic medicine and reconstructive surgery. Our video demonstrates a basic surgical approach that can be applied to simple cases of type III FGM presenting to the female pelvic surgeon.

Young females in the athletic arena.

There are factors that uniquely affect young females in sports. The sociologic aspects of female youth sports can be understood from a historical perspective. Athletics have an influence on the development of young girls, from gender identity and sexual orientation to the foundations of self-esteem and moral development. There is a relationship between certain psychopathologic conditions common in girls and athletics, including eating disorders, depression, and anxiety disorders. Although involvement in sports may engender some of these problems, others may be successfully treated through physical exercise.

To compare the effectiveness and complications of TVT-Abbrevo (tension-free vaginal tape-Abbrevo) and TVT-Obturator (tension-free vaginal tape-obturator) for the treatment of female stress urinary incontinence (SUI). From Nov.2012 to Nov.2013, 117 patients suffering from SUI were treated with TVT-Abbrebo (n=79) or TVT-Obturator (n=38) procedure, the clinical efficacy and operation-correlated complications were observed. A total of 117 cases, 107 cases of urinary incontinence symptoms disappeared completely, 10 cases were improved. 72 cases (91.1%) were cured and 7 cases (8.9%) were improved in TVT-Abbrevo group; 35 cases (92.1%) were cured and 3 cases (7.9%) were improved in TVT-Obturator group. No significant differences could be found for the curing rates between two groups (P>0.05). Compared with the TVT-Obturator group, the TVT-Abbrevo group had less patients complaining of inner thigh pain at 24 h and 1 w after surgery (PTVT-Abbrevo and TVT-Obturator group (P>0.05). No intraoperative complications such as blood vessel, nerve, bladder damage were recorded and no postoperative retropubic hematoma, tape adjustment and other complications occurred in two goups. No recurrence after 1 year follow-up. The study shows that TVT-Abbrevo procedure is safe and efficacy in treatment of SUI, and associated with low incidence of recent postoperative inner thigh pain.

This paper has attempted to assess the changes noted in the trends in the incidence and biochemical pattern of female urolithiasis patients during the period 1971-2008. A prospective descriptive clinical study was done on 8,590 stone patients belonging to both sexes treated at the urinary stone clinic. The incidence of stone disease among the two sexes was plotted. The various metabolic parameters including 24-h urine volume, urine calcium, phosphorus, uric acid, oxalate, magnesium, creatinine and citrate, serum creatinine, calcium, phosphorus, uric acid and magnesium and calculated parameter calcium:magnesium ratio were studied. The possible causes for the change in incidence of stone disease in the female sex were elucidated. Of the patients studied, 12.7% (1,091) were females. There was a definite increase in the incidence of female urolithiasis over the past 37 years (P stone genesis, together with the increased excretion of calcium and oxalate may have contributed to the increasing incidence of stone disease in females. This might be due to changes in living standards and dietary habits.

Full Text Available Objectives To investigate changing nutritional demographics of treated HIV-1-infected patients and explore causes of obesity, particularly in women of African origin.Methods We prospectively reviewed nutritional demographics of clinic attenders at an urban European HIV clinic during four one-month periods at 3-yearly intervals (2001, 2004, 2007, and 2010 and in two consecutive whole-year reviews (2010-11 and 2011-12. Risk-factors for obesity were assessed by multiple linear regression. A sub-study of 50 HIV-positive African female patients investigated body-size/shape perception using numerical, verbal and pictorial cues. Results We found a dramatic rise in the prevalence of obesity (BMI >30 kg/m2, from 8.5% (2001 to 28% (2011-12 for all clinic attenders, of whom 86% were on antiretroviral treatment. Women of African origin were most affected, 49% being obese, with a further 32% overweight (BMI 25-30 kg/m2, in 2012. Clinical factors strongly associated with obesity included female gender, black African ethnicity, non-smoking, age and CD4 count (all P<0.001; greater duration of cART did not predict obesity. Individual weight-time trends mostly showed slow long-term progressive weight gain. Investigating body weight perception, we found that weight and adiposity were underestimated by obese subjects, who showed a greater disparity between perceived and actual adiposity (P<0.001. Obese subjects targeted more obese target ideal body shapes (P<0.01, but were less satisfied with their body shape overall (P=0.02. Conclusions Seropositive African women on antiretroviral treatment are at heightened risk of obesity. Although multifactorial, bodyweight perception represents a potential target for intervention.

Fertility Effects on Female Labor Supply

Lundborg, Petter; Plug, Erik; Rasmussen, Astrid Würtz

This paper introduces a new IV strategy based on IVF induced fertility variation in childless families to estimate the causal effect of having children on female labor supply using IVF treated women in Denmark. Because observed chances of IVF success do not depend on labor market histories, IVF...... treatment success provides a plausible instrument for childbearing. Our IV estimates indicate that fertility effects are: (a) negative, large and long lasting; (b) much stronger at the extensive margin than at the intensive margin, and (c) similar for mothers, not treated with IVF, which suggests that IVF...

The present study characterized the effects of ketamine on sexual behavior and anxiety in female rats. In Experiment 1, female subjects received an injection of ketamine (10.0mg/kg) or saline 30min prior to a sexual partner-preference test during which each female subject was given the opportunity to interact with a female stimulus or a sexually vigorous male stimulus. Immediately afterwards, female subjects were tested for locomotion in an open field test. Ketamine-treated subjects spent significantly more time with the male stimulus than saline-treated subjects. No other measures of mating behavior (i.e., paced mating behavior, lordosis) were affected by ketamine. Ketamine also had no effect on locomotion. In Experiment 2, female subjects received an injection of ketamine (10.0mg/kg), or saline daily for 10days to investigate the possibility that sexual dysfunction emerges only after repeated exposure. Similar to the results of Experiment 1, ketamine-treated subjects spent significantly more time with the male stimulus than saline-treated subjects. Chronic ketamine treatment also decreased the likelihood of leaving the male after mounts, without affecting any other measures of sexual behavior. Chronic ketamine had no effect on locomotion. In Experiment 3, female subjects received an injection of ketamine (10.0mg/kg) or saline and were tested for anxiety in an elevated plus maze test and for locomotion in an open field test. Acute ketamine had no effect on anxiety or locomotion. In Experiment 4, female subjects received an injection of ketamine (10.0mg/kg) or saline daily for 10days to investigate the possibility that anxiety emerges only after repeated exposure. Chronic ketamine exposure had no effect on any measure of anxiety. However, chronic ketamine exposure increased locomotion. The results from these experiments indicate that unlike other medications prescribed for depression, neither acute nor chronic ketamine treatment causes anxiety or disruption of

Bemisia tabaci females from the Mediterranean (Q) species detect and avoid laying eggs in the presence of pyriproxyfen, a juvenile hormone analogue.

Moshitzky, Pnina; Morin, Shai

2014-10-01

Pyriproxyfen, a juvenile hormone analogue, disrupts embryogenesis, metamorphosis and adult formation in Bemisia tabaci, but does not directly affect adult females. The effect of pyriproxyfen on egg-laying preference and performance of B. tabaci females and the influence of resistance to pyriproxyfen on these reproductive behaviours were studied. Choice experiments utilising cotton plants treated and not treated with pyriproxyfen revealed a significant preference for egg laying on non-treated plants both by resistant and susceptible females. No-choice assays indicated a reduction of ∼60% in the number of eggs laid on pyriproxyfen-treated plants by both resistant and susceptible females. The reduction in oviposition on treated plants was not accompanied with reduced expression of the vitellogenin gene or a delay in oocyte maturation, but significant accumulation of mature oocytes in the ovaries was observed, and could be reversed by transferring the females to non-treated plants. Pyriproxyfen caused reduced oviposition and enhanced mature oocyte accumulation in pyriproxyfen-resistant and pyriproxyfen-susceptible females. These findings can be explained by two alternative mechanisms: pyriproxyfen-regulated physiological arrest of oviposition, involving hormonal regulation of myotrophic factors, or the hierarchy-threshold behavioural theory of host choice, in which pyriproxyfen-treated plants are defined as low-quality hosts. Aspects of application are discussed. © 2013 Society of Chemical Industry.

Reproduction in female yaks (Bos grunniens) and opportunities for improvement.

Science.gov (United States)

Zi, Xiang-Dong

2003-03-01

This paper reviews seasonal breeding, puberty, postpartum anestrus, embryonic loss and calf survival and their constraints in female yaks. Methods for improving fertility in postpartum yak cows are also considered. Yaks are seasonal breeders with mating and conception restricted in the warm season. Puberty generally occurs in the 2nd to the 4th warm season following birth, i.e. between 13 and 36 months of age. The cows usually have a long postpartum anestrus period; only a small proportion of the cows return to estrus in the 1st breeding season after calving, most come into estrus in the 2nd and 3rd years. Nutritional status is the most important determinant of reproduction in female yaks. Reproductive success is a direct result of the availability of pasture determined by climate, season, and management practices. Milking delays puberty by reducing milk intake (restricted suckling) and growth rate for the calf. Milking interferes with grazing and prolongs the duration of postpartum acyclicity in cows. Calves born early in the season have a longer suckling season than those born later in the season before the onset of winter. Thus, they can have their first cycle in the breeding season of the following year, while those born late in the season may not have their first estrus until 25 or 26 months of age. Cows calving early in the season are more likely to return to estrus in the year of calving because they have a longer period to recover from the demand on body reserves before the onset of winter. Inbreeding in smallholder yak farms is also discussed and minimizing inbreeding by exchanging bulls among different herds is suggested. Reproductive efficiency can be improved by nutritional supplementation during the winter, however, the most cost-effective and practical strategy for this needs to be determined. Early weaning or restricted suckling may shorten the duration of postpartum acyclicity, however, it is impractical due to reduced growth rates and increased

Women make up about 14 percent of general dentists in the United States, and the proportion is projected to exceed 29 percent by 2020. The authors obtained dental benefits claims data from the Washington Dental Service (WDS), Seattle, and used them to examine the practice patterns of 265 women and 1,947 men engaged in general dentistry for at least 26 days in 2001. Practice variables of interest included age, days worked, procedures performed and total income from WDS reimbursements and patient copayments. The number, age and sex of patients treated also were obtained. Using productivity data, the authors also estimated the potential impact of an increase in the percentage of female dentists in the state. The authors found no differences between male and female dentists in the number of procedures per patient, income per patient or income per day of work. Frequency distributions of various services were highly similar for both groups. Multiple regression models showed no influence of dentist's sex on total income. However, the mean and median numbers of days worked were about 10 percent lower for female dentists than for male dentists. This difference was consistent with the finding that female dentists treated approximately 10 percent fewer patients, performed about 10 percent fewer procedures and had a combined income of about 10 percent less than that of male dentists. Practice patterns of male and female dentists generally were equivalent in this WDS population. Female and male dentists provided a similar range of services and earned an equal income per patient treated and per day worked. However, women worked fewer days per year than did men, irrespective of age. If the dental work force and practice patterns remain unchanged otherwise, the total number of patients treated per dentist will decrease slightly as women make up an increasing proportion of dentists.

Hormonal therapy in female pattern hair loss

Kevin R. Brough

2017-03-01

Full Text Available Female pattern hair loss is the most common cause of hair loss in women and one of the most common problems seen by dermatologists. This hair loss is a nonscarring alopecia in which loss occurs on the vertex scalp, generally sparing the frontal hairline. Hair loss can have significant psychosocial effects on patients, and treatment can be long and difficult. The influence of hormones on the pathogenesis of female pattern hair loss is not entirely known. The purpose of this paper is to review physiology and potential hormonal mechanisms for the pathogenesis of female pattern hair loss. We also discuss the current hormonal and hormone-modifying therapies that are available to providers as they partner with patients to treat this frustrating issue.

Full Text Available Objective: Assessment of preoperative and postoperative outcomes of patients that were performed hysterescopic intrauterine adhesiolysis. Material and method: We reviewed 24 patients that underwent hysterescopy with the complaints of amenorrhea, hypomenorrhea, recurrent pregnancy loss between 2004-2008. The most complaints of patients were infertilty amenorrhea. Results: Adhesions occurs mainly as a result of trauma to the gravid uterine cavity in 14 patients. When classifying patients with their intrauterine adhesions, Grade 3 was the most frequently seen. Adhesiolisis was performed with hysteresopic scissors in all patients. In postoperative period following synechiolysis, 10 patients were treated with estrogen and progestogen, 11 of them used intrauterine device with estrogen and progestogen therapy, foley catheter was used in 3 patients. Hysterescopy was performed in 5 patients for second time because of adhesion suspicions. The re-adhesiolysis performed to 3 patients because of determined to mild adhesion. Conclusion: After hysterescopic adhesiolysis, all patients with the complaint of amenorrhea had regular menstruation. Pregnancy after treatment occured in 4 patients but live birth rate was 75%.

Emission of compounds with biological activities from waste water treatment plant (WWTP) effluents into surface waters is a topic of concern for ecology and drinking water quality. We investigated the occurrence of hormone-like activities in waste water sample extracts from four Dutch WWTPs and pursued to identify compounds responsible for them. To this aim, in vitro reporter gene bioassays for androgenic, anti-androgenic, estrogenic, glucocorticoid and progestogenic activity and a UPLC-tQ-MS target analysis method for 25 steroid hormones used in high volumes in pharmacy were applied. Principal component analysis of the data was performed to further characterize the detected activities and compounds. All five types of activities tested were observed in the WWTP samples. Androgenic and estrogenic activities were almost completely removed during WW treatment, anti-androgenic activity was only found in treated WW. Glucocorticoid and progestogenic activities persisted throughout the treatment. The androgenic activity in both influent could predominantly be attributed to the presence of androstenedione and testosterone. Anti-androgenic activity was explained by the presence of cyproterone acetate. The glucocorticoid activity in influent was fully explained by prednicarbate, triamcinolone acetonide, dexamethasone and amcinonide. In effluent however, detected hormones could only explain 10-32% of the activity, indicating the presence of unknown glucocorticoids or their metabolites in effluent. Progesterone and levonorgestrel could explain the observed progestogenic activity. The principle component analysis confirmed the way in which hormones fit in the spectrum of other emerging contaminants concerning occurrence and fate in WWTPs. Copyright © 2018 Elsevier B.V.

To determine the etiology and management outcome of bladder outlet obstruction (BOO) in female. Methodology: From 2009 to 2012, 37 females with a mean age of 40 (range 20-65) were investigated for etiology and management outcome of BOO. Typical complaints were slow urinary flow, difficulty in emptying bladder, frequency of micturition and urgency. Mean duration of symptoms was 6 month. Results: 15 women were confirmed as atrophic urethritis, 5 had functional bladder, 3 had urethral caruncle, 5 had cystocele, 7 had complete procedentia of uterus, and 2 had impacted urethral stone. Cystoscopy was performed in all patients to exclude other pathology like vesical stone and bladder growth. 12 patients were referred to Gynecology due to complete procedentia of uterus and cystocele. Three cases of urethral caruncle were treated by excision and biopsy, 2 patients with urethral stone were treated by endoscopic push back and litholapaxy while 5 required conservative treatment and 15 cases of atrophic urethritis were kept on Hormone Replacement Therapy (HRT). Conclusion: BOO is uncommon in female and management depends upon the etiology. (author)

Suicide and substance use among female veterans: a need for research.

The number of female veterans is increasing. Veterans Administration (VA) enrollment increased over 40% from past eras. However, little research has focused on their mental health. We reviewed literature to examine associations of substance use with suicide in female veterans, identify research gaps, and inform future studies. Google Scholar, Pub Med, and PsychINFO were searched using: substance use, female veteran, and suicide. Exclusion criteria (e.g., not discussing U.S. veterans) left 17 articles. Nine studies examined completed suicide among veterans. In most recent years, rates of deaths were greater for veterans than nonveterans, including females. Completed suicide was associated with past trauma, young age, and a mental disorder. Studies have often not addressed substance use. Three studies examined completed suicide among VA treated veterans without examining substance use as an associated factor. Rates of completed suicides were also higher among veterans than nonveterans, including females. A large proportion of females also had a mental diagnosis. Five studies examined substance use and attempted or completed suicide among VA treated veterans. Veterans in poor mental health had increased odds of suicide mortality; women with a substance use disorder (SUD) had a higher hazard ratio for completed suicide than men with a SUD. Engagement in substance abuse treatment decreased odds of suicide attempt among veterans. Available data suggest that suicide rates are higher among female veterans than women in the general population. Substance use may increase the likelihood of suicidal behaviors among female veterans, particularly those with a mental diagnosis. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Abstract This systematic review aims to assess the efficacy of aromatase inhibitors (AIs in treating pain symptoms caused by endometriosis. A comprehensive literature search was conducted to identify all the published studies evaluating the efficacy of type II nonsteroidal aromatase inhibitors (anastrozole and letrozole in treating endometriosis-related pain symptoms. The MEDLINE, EMBASE, PubMed, and SCOPUS databases and the Cochrane System Reviews were searched up to October 2010. This review comprises of the results of 10 publications fitting the inclusion criteria; these studies included a total of 251 women. Five studies were prospective non-comparative, four were randomized controlled trials (RCTs and one was a prospective patient preference trial. Seven studies examined the efficacy of AIs in improving endometriosis-related pain symptoms, whilst three RCTs investigated the use of AIs as post-operative therapy in preventing the recurrence of pain symptoms after surgery for endometriosis. All the observational studies demonstrated that AIs combined with either progestogens or oral contraceptive pill reduce the severity of pain symptoms and improve quality of life. One patient preference study demonstrated that letrozole combined with norethisterone acetate is more effective in reducing pain and deep dyspareunia than norethisterone acetate alone. However, letrozole causes a higher incidence of adverse effects and does not improve patients' satisfaction or influence recurrence of symptoms after discontinuation of treatment. A RCT showed that combining letrozole with norethisterone acetate causes a lower incidence of adverse effects and lower discontinuation rate than combining letrozole with triptorelin. Two RCTs demonstrated that, after surgical treatment of endometriosis, the administration of AIs combined with gonadotropin releasing hormone analogue for 6 months reduces the risk of endometriosis recurrence when compared with gonadotropin

Throughout every pregnancy, genetically distinct fetal microchimeric stem/progenitor cells (FMCs) engraft in the mother, persist long after delivery, and may home to damaged maternal tissues. Phenotypically normal fetal lymphoid progenitors have been described to develop in immunodeficient mothers in a fetus-treats-its-mother paradigm. Since stem cells contribute to muscle repair, we assessed this paradigm in the mdx mouse model of Duchenne muscular dystrophy. mdx females were bred serially to either ROSAeGFP males or mdx males to obtain postpartum microchimeras that received either wild-type FMCs or dystrophin-deficient FMCs through serial gestations. To enhance regeneration, notexin was injected into the tibialis anterior of postpartum mice. FMCs were detected by qPCR at a higher frequency in injected compared to noninjected side muscle (P=0.02). However, the number of dystrophin-positive fibers was similar in mothers delivering wild-type compared to mdx pups. In addition, there was no correlation between FMC detection and percentage dystrophin, and no GFP+ve FMCs were identified that expressed dystrophin. In 10/11 animals, GFP+ve FMCs were detected by immunohistochemistry, of which 60% expressed CD45 with 96% outside the basal lamina defining myofiber contours. Finally we confirmed lack of FMC contribution to statellite cells in postpartum mdx females mated with Myf5-LacZ males. We conclude that the FMC contribution to regenerating muscles is insufficient to have a functional impact.

Long-acting GSK1265744 (GSK744 LA) is a strand transfer inhibitor of the HIV/SIV (simian immunodeficiency virus) integrase and was shown to be an effective preexposure prophylaxis (PrEP) agent in a low-dose intrarectal SHIV (simian-human immunodeficiency virus) rhesus macaque challenge model. We examined the pharmacokinetics and efficacy of GSK744 LA as PrEP against repeat high-dose intravaginal SHIV challenge in female rhesus macaques treated with Depo-Provera (depot medroxyprogesterone acetate), which promotes viral transmission vaginally. When Depo-Provera-treated female rhesus macaques were dosed with GSK744 LA (50 mg/kg) monthly, systemic and tissue drug concentrations were lower than previously observed in male rhesus macaques. GSK744 concentrations were fivefold lower on average in cervical tissues than in rectal tissues. Eight female rhesus macaques were treated with GSK744 LA at week 0, and four female rhesus macaques served as controls. All animals received a high-dose challenge of SHIV162P3 at week 1. No infection was detected in GSK744 LA-treated rhesus macaques, whereas viremia was detected 1 to 2 weeks after SHIV challenge in all control animals. The GSK744 LA-treated rhesus macaques were given a second administration of drug at week 4 and further challenged at weeks 5 and 7. GSK744 LA treatment protected six of eight female rhesus macaques against three high-dose SHIV challenges, whereas all control animals became infected after the first challenge (P = 0.0003, log-rank test). These results support further clinical development of GSK744 LA for PrEP. Copyright © 2015, American Association for the Advancement of Science.

Full Text Available Abstract Background For the conclusive diagnosis of Cushing's Syndrome, a stimulating ACTH test or a low suppressive Dexamethasone test is used. Reports in other species than the dog indicate that plasma cortisol concentration after ACTH administration is affected by gender. We investigated the effect of gender on the cortisol response to ACTH and Dexamethasone tests in dogs. Methods Seven healthy adult Cocker Spaniels (4 females and 3 males were assigned to a two by two factorial design: 4 dogs (2 females and 2 males received IV Dexamethasone 0.01 mg/kg, while the other 3 dogs received an IV saline solution (control group. Two weeks later the treatments were reversed. After one month, ACTH was given IV (250 μg/animal to 4 dogs (2 female and 2 males while the rest was treated with saline solution (control group. Cortisol concentrations were determined by a direct solid-phase radioimmunoassay and cholesterol and triglycerides by commercial kits. Results and Discussion No effect of treatment was observed in metabolite concentrations, but females presented higher cholesterol concentrations. ACTH-treated dogs showed an increase in cortisol levels in the first hour after sampling until 3 hours post injection. Cortisol concentrations in Dexamethasone-treated dogs decreased one hour post injection and remained low for 3 hours, thereafter cortisol concentrations increased. The increase in cortisol levels from one to two hours post ACTH injection was significantly higher in females than males. In Dexamethasone-treated males cortisol levels decreased one hour post injection up to 3 hours; in females the decrease was more pronounced and prolonged, up to 5 hours post injection. Conclusion We have demonstrated that cortisol response to ACTH and Dexamethasone treatment in dogs differs according to sex.

Many types of hormonal contraceptives are in use nowadays for example oral pills, emergency contraceptive pills, vaginal rings, implantable rods and injectable contraceptives (combined and progestogens only). The purpose of this study was to determine and compare serum serotonin levels in married fertile females of reproductive age group using hormonal contraceptives with non-contraceptive users. A total of 300 women were selected in the study. This cross sectional study included three groups; Group-1 (control), group-2 (combined oral contraceptive users) and group-3 (injectable contraceptive users). History and examination of subjects were recorded on pro forma. Levels of serum serotonin were measured using standard ELISA kits. Results were analysed by one way ANOVA and a p-value 0.05% was taken as significant, using SPSS 16.0. The mean age of the patients in group-1 was 30.4 ± 6.1 years, group-2 was 28.9 ± 4.9 and in group-3 was 2.5 ± 6.8 years. For subjects in group-1, group-2 and group 3 the mean ± SD concentration of serum serotonin was 160.68 ± 53.27 ng/dl, 227.3 ± 63.98 ng/dl and 118.19 ± 31.32 ng/dl. A significant (p = 0.00) difference was seen among three groups, i.e., group-1, group-2 and group-3. After applying Post HOC Tukey's HSD, there was statistically no significant difference between group-1 and group-2 (p = 0.956). Difference was seen between group-2 and group-3 (p = 0.00), it was also significant between group-3 and group-1 (p = 0.00). It was concluded that hormonal contraceptives affect the levels of serum serotonin.

Carvacrol is the major constituent of essential oils from aromatic plants. It showed antimicrobial, anticancer and antioxidant properties. Although it was approved for food use and included in the chemical flavorings list, no indication on its safety has been estimated. Since the use of plant extracts is relatively high among women, aim of this study was to evaluate carvacrol effects on female physiology and endocrine profiles by using female rats in proestrus and diestrus phases. Serotonin and metabolite tissue content in prefrontal cortex and nucleus accumbens, after carvacrol administration (0.15 and 0.45 g/kg p.o.), was measured. Drug effects in behavioral tests for alterations in motor activity, depression, anxiety-related behaviors and endocrine alterations were also investigated. While in proestrus carvacrol reduced serotonin and metabolite levels in both brain areas, no effects were observed in diestrus phase. Only in proestrus phase, carvacrol induced a depressive-like behavior in forced swimming test, without accompanying changes in ambulation. The improvement of performance in FST after subchronic treatment with fluoxetine (20 mg/kg) suggested a specific involvement of serotonergic system. No differences were found across the groups with regard to self-grooming behavior. Moreover, in proestrus phase, carvacrol reduced only estradiol levels without binding hypothalamic estradiol receptors. Our study showed an estrous-stage specific effect of carvacrol on depressive behaviors and endocrine parameters, involving serotonergic system. Given the wide carvacrol use not only as feed additive, but also as cosmetic essence and herbal remedy, our results suggest that an accurate investigation on the effects of its chronic exposure is warranted. - Highlights: → Carvacrol induced a depressive-like phenotype in rats, depending on ovarian cyclicity. → Carvacrol selectively reduced serotonin content in female rats in proestrus phase. → Carvacrol reduced serotonin

Staphylococcus saprophyticus is a rarely reported agent of urinary tract infection (UTI) in the pediatric population. In our retrospective 3-year study, S. saprophyticus comprised 24.5% of 106 isolates of UTIs in female adolescents 12-15 years of age who attended an emergency department. Clinicians should be aware of the high prevalence of this etiology when empirically treating UTIs in female adolescents.

Full Text Available Catastrophic antiphospholipid syndrome (CAPS is a rare but potentially life-threatening condition characterized by diffuse vascular thrombosis, leading to multiple organ failure developing over a short period of time in the presence of positive antiphospholipid antibodies (aPL. CAPS is a severe form of antiphospholipid syndrome, developing in about 1% of cases of classic antiphospholipid syndrome, manifesting as microangiopathy, affecting small vessels of multiple organs. It is acute in onset, with majority of cases developing thrombocytopenia and less frequently hemolytic anemia and disseminated intravascular coagulation. Lupus anticoagulant and anticardiolipin antibodies have been reported as predominant antibodies associated with CAPS. Treatment options often utilized in CAPS include anticoagulation, steroids, plasma exchange, cyclophosphamide therapy, and intravenous immunoglobulin therapy. Even though the reported incidence of this condition is considered to be low, the mortality rate is approaching 50%. The high rate of mortality should warrant greater awareness among clinicians for timely diagnosis and treatment of this life-threatening condition. Studies have shown that complement activation plays a key role in the pathogenesis of aPL mediated thrombosis in CAPS. We report a case of a 36-year-old female admitted with clinical and laboratory findings consistent with CAPS successfully treated with eculizumab, a terminal complement inhibitor.

Prenatal testosterone excess leads to neuroendocrine, ovarian, and metabolic disruptions, culminating in reproductive phenotypes mimicking that of women with polycystic ovary syndrome (PCOS). The objective of this study was to determine the consequences of prenatal testosterone treatment on periovulatory hormonal dynamics and ovulatory outcomes. To generate prenatal testosterone-treated females, pregnant sheep were injected intramuscularly (days 30-90 of gestation, term=147 days) with 100 mg of testosterone-propionate in cottonseed oil semi-weekly. Female offspring born to untreated control females and prenatal testosterone-treated females were then studied during their first two breeding seasons. Sheep were given two injections of prostaglandin F2alpha 11 days apart, and blood samples were collected at 2-h intervals for 120 h, 10-min intervals for 8 h during the luteal phase (first breeding season only), and daily for an additional 15 days to characterize changes in reproductive hormonal dynamics. During the first breeding season, prenatal testosterone-treated females manifested disruptions in the timing and magnitude of primary gonadotropin surges, luteal defects, and reduced responsiveness to progesterone negative feedback. Disruptions in the periovulatory sequence of events during the second breeding season included: 1) delayed but increased preovulatory estradiol rise, 2) delayed and severely reduced primary gonadotropin surge in prenatal testosterone-treated females having an LH surge, 3) tendency for an amplified secondary FSH surge and a shift in the relative balance of FSH regulatory proteins, and 4) luteal responses that ranged from normal to anovulatory. These outcomes are likely to be of relevance to developmental origin of infertility disorders and suggest that differences in fetal exposure or fetal susceptibility to testosterone may account for the variability in reproductive phenotypes.

This research examined the phytoestrogen potential of Calliandra calothyrsus leaf extract in prepubertal female rat (Rattus norvegicus). Sixty weaned female rats (21 days old) were divided into five groups i.e. control (K), negative control which was given 0.5% Na CMC suspension (KN) and treatment groups which were given with C. calothyrsus ethanolic leaf extract doses 25 mg/kg bw (P1), 50 mg/kg bw (P2) and 75 mg/kg bw (P3). The treatment suspension was administered 0.5 mL/rat/day by gavage for 28 days, started at the age of 21st days old. The rats were sacrificed and the blood samples were collected from 4 rats / group at the age of 28th, 42nd and 56th days old, each. The concentration of estrogen hormone levels were measured from blood serum by ELISA kit and were read at 450 nm wavelength with an ELISA Spectrophotometer. Data was analyzed statistically by General Linear Model with 95% of confidence. The result showed that rat’s body weight decreased significantly with the higher doses and the longer the treatment of C. calothyrsus leaf extract due to the anti-nutritive activity of calliandra tannins. The estrogen hormone level was significantly increased at the highest dose. The highest estrogen levels were found in the group of female rats which were given the exctract of 75 mg/kg bw until the age of 42nd days. This results showed that there was a phytoestrogen potential in the C. calothyrsus leaf extract.

The transmission of pathogens, antibodies, and proteins is a possible consequence of blood product transfusion. A female patient had an unexpected positive serum β-human chorionic gonadotropin result, indicative of pregnancy, after she had received a transfusion with 1 unit of platelet concentrate, 4 units of red blood cells, and 4 units of pooled solvent/detergent-treated plasma (Octaplas). To investigate the possibility of passive transfusion of β-human chorionic gonadotropin from the plasma transfusion, one additional unit from the same batch was thawed and analyzed. To validate the β-human chorionic gonadotropin assay for use in solvent/detergent-treated plasma and to investigate any interference in the assay, dilution experiments were performed using the implicated plasma batch diluted with male and non-pregnant female sera. Also, plasma from a known pregnant woman was diluted with Octaplas (tested negative for β-human chorionic gonadotropin) and with a male serum to validate the assay for use in solvent/detergent-treated plasma. The implicated solvent/detergent-treated plasma had a mean β-human chorionic gonadotropin level of 91.5 mIU/mL. Results from the dilution experiments revealed an excellent correlation (r > 0.99) between β-human chorionic gonadotropin measurement in solvent/detergent-treated plasma and male serum and no over or under recovery of the expected results. Further measurements of β-human chorionic gonadotropin levels in the female recipient revealed an estimated half-life of 6 hours. This case demonstrates the importance of considering the possibility of passive transmission of analytes to a patient from the transfusion of blood products. Furthermore, the measurement of β-human chorionic gonadotropin is valid in solvent/detergent-treated plasma using a Roche Cobas analyzer. © 2017 AABB.

1978-01-01

One-day-old adults of the Indian meal moth, Plodia interpunctella (Huebner), were irradiated (I) with either 35 krad (a partially sterilizing dose) or 50 krad (a sterilizing dose) and combined with untreated (U) adults at numbers of 1, 5, 10, 15, or 25 treated males or females per pair of untreated adults. At 25 males per pair, egg hatch was reduced to 4.8 and 22.2% at 35 and 50 krad, respectively. The calculated degree of competitiveness showed that both males and females were more competitive after treatment with 35 krad than after treatment with 50 krad and that treated females were more competitive (based on percentage egg hatch) at both doses than corresponding males. Irradiated females were fully competitive at most release ratios, but I males were not fully competitive even at the higher release ratios, although the decreases were not large enough to seriously affect their use for field control.

We studied the lumbar spines of 117 adults (39 women and 78 men) with spondylolysis unrelated to low back pain using multidetector computed tomography (CT). Of the 117 subjects with spondylolysis, including five with multiple-level spondylolysis, there were 124 vertebrae with spondylolysis. In adult lumbar spines with unilateral spondylolysis, there was no significant difference between the incidence of spondylolisthesis in female and male subjects. However, in those with bilateral spondylolysis, there was a significantly higher incidence of spondylolisthesis in female subjects (90.9%) than in males (66.2%). Furthermore, females with bilateral spondylolysis had significant more slippage than males. Lumbar index and lumbar lordosis were not significantly different between male and female subjects, and did not significantly correlate with slippage. In conclusion, to treat acute spondylolysis in adolescents, it is important to obtain bony union at least unilaterally, especially in female subjects, to prevent further slippage.

Rural female adolescence: Indian scenario.

Kumari, R

1995-01-01

This article describes the life conditions of female adolescents in India and issues such as health, discrimination in nutrition and literacy, child labor, early marriage, juvenile delinquency, and violence against girls in rural areas of India. Data are obtained from interview samples conducted among 12 villages in north India. Female adolescents suffer from a variety of poverty-ridden village life conditions: caste oppression, lack of facilities, malnutrition, educational backwardness, early marriage, domestic burden, and gender neglect. Girls carry a heavy work burden. Adolescence in rural areas is marked by the onset of puberty and the thrust into adulthood. Girls have no independent authority to control their sexuality or reproduction. Girls are expected to get married and produce children. Control of female sexuality is shifted from the father to the husband. There is a strong push to marry girls soon after menstruation, due to the burden of imposing strict restrictions on female sexuality, the desire to reduce the burden of financial support, and the need to ensure social security for daughters. Girls may not go out alone or stay outside after dark. Many rural parents fear that education and freedom would ruin their daughter. Girls develop a low self-image. Rural villages have poor sanitation, toilet facilities, and drainage systems. Girls are ignorant of health and sex education and lack access to education. The neglect of female children includes malnutrition, sex bias, and early marriage. In 1981, almost 4 out of every 100 girls had to work. 5.527 million girls 5-14 years old were child laborers. Girls are veiled, footbound, circumcised, and burnt by dowry hungry in-laws. Female delinquents are subjected to sexual harassment and sometime to sexual abuse while in custody. Cows are treated better in rural India than women. Gender disparity is caused by the perpetuation of patriarchal masculine values.

Gender-specific induction of cytochrome P450s in nonylphenol-treated FVB/NJ mice

Nonylphenol (NP) is a breakdown product of nonylphenol ethoxylates, which are used in a variety of industrial, agricultural, household cleaning, and beauty products. NP is one of the most commonly found toxicants in the United States and Europe and is considered a toxicant of concern because of its long half-life. NP is an environmental estrogen that also activates the pregnane X-receptor (PXR) and in turn induces P450s. No study to date has examined the gender-specific effects of NP on hepatic P450 expression. We provided NP at 0, 50 or 75 mg/kg/day for 7 days to male and female FVB/NJ mice and compared their P450 expression profiles. Q-PCR was performed on hepatic cDNA using primers to several CYP isoforms regulated by PXR or its relative, the constitutive androstane receptor (CAR). In female mice, NP induced Cyp2b10 and Cyp2b13, and downregulated the female-specific P450s, Cyp3a41 and Cyp3a44. In contrast, male mice treated with NP showed increased expression of Cyp2a4, Cyp2b9, and Cyp2b10. Western blots confirmed induction of Cyp2b subfamily members in both males and females. Consistent with the Q-PCR data, Western blots showed dose-dependent downregulation of Cyp3a only in females and induction of Cyp2a only in males. The overall increase in female-predominant P450s in males (Cyp2a4, 2b9) and the decrease in female-predominant P450s in females (Cyp3a41, 3a44) suggest that NP is in part feminizing the P450 profile in males and masculinizing the P450 profile in females. Testosterone hydroxylation was also altered in a gender-specific manner, as testosterone 16α-hydroxylase activity was only induced in NP-treated males. In contrast, NP-treated females demonstrated a greater propensity for metabolizing zoxazolamine probably due to greater Cyp2b induction in females. In conclusion, NP causes gender-specific P450 induction and therefore exposure to NP may cause distinct pharmacological and toxicological effects in males compared to females

2007-01-01

The clinical characteristics of head trauma were evaluated in 18 wrestlers belonging to a female professional wrestling organization, 13 regular members and five trainees aged 15-34 years. Medical examinations for head trauma were performed in all wrestlers, and wrestlers treated at our emergency outpatient department were clinically evaluated. In addition, the relationships of head trauma with duration of the wrestling career of 1-16 years (mean 8 years) in the regular members, and less than 1 year in the five trainees, and body mass index (BMI) of 21.0-32.0 in the 16 subjects, excluding two trainees, was evaluated. Chronic symptoms were noted in four of the 18 wrestlers with long wrestling careers (16 years in 1, 13 years in 1, and 5 years in 2). Three wrestlers with symptoms immediately after head trauma showed recurrent retrograde amnesia and had low BMI (21.6, 21.6, and 23.1). Five wrestlers were treated at our emergency outpatient clinic, three required hospitalization and two showed intracranial traumatic changes on computed tomography (acute subdural hematoma in 1 and diffuse brain swelling in 1). Head trauma in female professional wrestlers is associated with longer wrestling career and low BMI. Periodic medical examinations are recommended to monitor for signs of head trauma. (author)

Previous studies have demonstrated that female gender could be a prognostic factor in limited-disease (LD) small-cell lung cancer (SCLC), but the correlation between patient gender and survival parameters remains unclear. Data from 179 LD SCLC patients treated with definitive chemoradiotherapy (CRT) were reviewed. Influence of patient gender on time to progression (TTP), local control (LC), brain metastasis-free (BMFS), distant metastasis-free (DMFS) and overall survival (OS) was analysed. Definitive CRT was completed by 179 (110 men/69 women) patients. Of these, 68 (38%; 34 men/34 women) patients were treated in concurrent and 111 (62%; 76 men/35 women) in sequential mode. Prophylactic cranial irradiation (PCI) was subsequently applied in 70 (39%; 36 men/34 women) patients with partial or complete response after CRT. Median OS was 20 (95% confidence interval [CI] 10-22) and 14 (95% CI 10-18) months in female and male patients, respectively (p = 0.021). In subgroups defined by remission status (complete and partial response) after CRT, an OS benefit for females compared to males was also detected. There was no correlation between patient gender and TTP, LC or DMFS, and no difference in OS in the female and male subgroups treated with PCI. The incidence of metachronous brain metastases (BMs) in the male and female subgroups differed significantly (40/110 men vs. 18/69 women, p = 0.03). Also, mean BMFS was significantly longer in women (p = 0.023). Patient gender also significantly correlated with OS on multivariate analysis after adjustment for other prognostic factors (p = 0.04, HR 1.38, 95% CI 1.08-1.92). In this heterogeneous LD SCLC patient cohort treated with definitive CRT, female gender was significantly associated with longer BMFS and OS, as well as with a lower incidence of metachronous brain failure.

2018-01-01

Sural neuralgia is persistent pain in the distribution of the sural nerve that provides sensation to the lateral posterior corner of the leg, lateral foot, and fifth toe. Sural neuralgia is a rare condition but can be challenging to treat and can cause significant limitation. We present 2 cases of sural neuralgia resistant to conservative management that were effectively treated by pulsed radiofrequency ablation. A 65-year-old female developed sural neuralgia after a foot surgery and failed conservative management. She had successful sural nerve blocks, and pulsed radiofrequency ablation led to an 80% improvement in her pain. A 33-year-old female presented with sural neuralgia secondary to two falls. The patient had tried several conservative modalities with no success. We performed diagnostic blocks and pulsed radiofrequency ablation, and the patient reported 80% improvement in her pain. Pulsed radiofrequency ablation may be a safe and effective treatment for patients with sural neuralgia that does not respond to conservative therapy. However, studies are needed to elucidate its effectiveness and safety profile.

Full Text Available The knowledge on the etiology of breast cancer has advanced substantially in recent years, and several etiological factors are now firmly established. However, very few new discoveries have been made in relation to occupational risk factors. The International Agency for Research on Cancer has evaluated over 900 different exposures or agents to-date to determine whether they are carcinogenic to humans. These evaluations are published as a series of Monographs (www.iarc.fr. For breast cancer the following substances have been classified as “carcinogenic to humans” (Group 1: alcoholic beverages, exposure to diethylstilbestrol, estrogen-progestogen contraceptives, estrogen-progestogen hormone replacement therapy and exposure to X-radiation and gamma-radiation (in special populations such as atomic bomb survivors, medical patients, and in-utero exposure. Ethylene oxide is also classified as a Group 1 carcinogen, although the evidence for carcinogenicity in epidemiologic studies, and specifically for the human breast, is limited. The classification “probably carcinogenic to humans” (Group 2A includes estrogen hormone replacement therapy, tobacco smoking, and shift work involving circadian disruption, including work as a flight attendant. If the association between shift work and breast cancer, the most common female cancer, is confirmed, shift work could become the leading cause of occupational cancer in women.

A variety of drug-delivery platforms have been employed to deliver therapeutic agents across cervicovaginal mucus (CVM) and the vaginal mucosa, offering the capability to increase the longevity and retention of active agents to treat infections of the female reproductive tract (FRT). Nanoparticles (NPs) have been shown to improve retention, diffusion, and cell-specific targeting via specific surface modifications, relative to other delivery platforms. In particular, polymeric NPs represent a promising option that has shown improved distribution through the CVM. These NPs are typically fabricated from nontoxic, non-inflammatory, US Food and Drug Administration-approved polymers that improve biocompatibility. This review summarizes recent experimental studies that have evaluated NP transport in the FRT, and highlights research areas that more thoroughly and efficiently inform polymeric NP design, including mathematical modeling. An overview of the in vitro, ex vivo, and in vivo NP studies conducted to date - whereby transport parameters are determined, extrapolated, and validated - is presented first. The impact of different NP design features on transport through the FRT is summarized, and gaps that exist due to the limitations of iterative experimentation alone are identified. The potential of mathematical modeling to complement the characterization and evaluation of diffusion and transport of delivery vehicles and active agents through the CVM and mucosa is discussed. Lastly, potential advancements combining experimental and mathematical knowledge are suggested to inform next-generation NP designs, such that infections in the FRT may be more effectively treated.

Prospective database study. To grasp the characteristics of surgically treated cases with lumbar spondylolysis or isthmic spondylolisthesis. A detailed analysis of surgically treated cases with spondylolysis or isthmic spondylolisthesis has never been reported. An epidemiological study in Japan conducted on 2000 subjects found the incidence of lumbar spondylolysis in the Japanese general population (population-based study) to be 5.9% (males: 7.9%, females: 3.9%). Among 124 vertebrae with spondylolysis, there were 0.8% L2 lesions, 3.2% L3 lesions, 5.6% L4 lesions, and 90.3% L5 lesions, including 5 cases (4.3%) with multiple-level lesions. We have been registering surgically treated spine cases in our database since 2000. From this database, we prospectively collected cases with lumbar spondylolysis or isthmic spondylolisthesis that were treated surgically between January 2000 and December 2009. We determined the age at surgery, sex, and vertebral level of spondylolysis. Of the 564 spondylolysis patients treated surgically, 66.8% were male and 33.2% were female. The mean age at surgery was 52.5 years (range, 13-84 y). There were 585 vertebrae with spondylolysis including 21 cases (3.7%) with multiple-level lesions. L5 spondylolysis affected 432 vertebrae and was the most common location (73.8%), followed by 125 L4 lesions (21.4%), 24 L3 lesions (4.1%), and 2 L2 lesions (0.7%). The percentage of L4 lesions in our study was significantly higher and of L5 lesions was significantly lower than those lesions' percentages in the population-based study. L4 spondylolysis may be more unstable or cause clinical symptoms more frequently leading to more surgical intervention. The percentage of multiple-level spondylolysis was similar between the 2 studies, suggesting these patients respond relatively well to conservative treatment. The male/female ratio was 2:1 in both studies, indicating that males and females require surgery at a similar frequency.

Decision-making in adolescent females who deliberately self-harm

Directory of Open Access Journals (Sweden)

Rigler Tristan

2016-01-01

Full Text Available Self-harming behaviour most commonly begins in adolescence and is more frequent among adolescent females. We explored the hypothesis that adolescent females who deliberately selfharm were more likely to perform worse on a decision-making task. Previous research in adolescents who self-harm reported impaired decision-making. However, research put little emphasis on older adolescents and the emotional learning. In our research, we presented the Iowa Gambling Task to 35 adolescent females who self-harmed and were treated at a psychiatric clinic, and to 35 healthy female controls. Our results show that in comparison to the control group the adolescents who self-harm took more risky decisions and were less concerned about the outcome. In addition, the clinical group also focused more on immediate gains and showed a reduced ability to learn from poor decisions in the past. Further research is suggested to explore the potential neurological correlates of decision-making and selfharming behaviour.

The objective of this study was to evaluate the gain in final height of achondroplasia (ACH) patients with long-term growth hormone (GH) treatment. We analyzed medical data of 22 adult patients (8 males and 14 females) treated with GH at a dose of 0.05 mg/kg/day. Optionally, tibial lengthening (TL) was performed with the Ilizalov method in 15 patients and TL as well as femoral lengthening (FL) in 6 patients. Concomitant gonadal suppression therapy with buserelin acetate was applied in 13 patients. The mean treatment periods with GH were 10.7 ± 4.0 and 9.3 ± 2.5 years for males and females, respectively. GH treatment augmented the final height +0.60 ± 0.52 SD (+3.5 cm) and +0.51 ± 1.29 SD (+2.8 cm) in males and females compared to non-treated ACH patients, respectively. Final height of ACH patients that underwent GH and TL increased +1.72 ± 0.72 SD (+10.0 cm) and +1.95 ± 1.34 SD (+9.8 cm) in males and females, respectively. GH, TL, and FL increased their final height +2.97 SD (+17.2 cm) and +3.41 ± 1.63 SD (+17.3 cm) in males and females, respectively. Gonadal suppression therapy had no impact on final height. Long-term GH treatment contributes to 2.6 and 2.1% of final adult height in male and female ACH patients, respectively.

OT was reported to be a direct regulator of bone mass in young rodents, and this anabolic effect on bone is a peripheral action of OT. The goal of this study was to investigate the peripheral action of oxytocin (OT) in the alveolar healing process in old female rats. Females Wistar rats (24-month-old) in permanent diestrus phase, received two ip (12h apart) injections of saline (NaCl 0.15M - control group) or OT (45μg/rat - treated group). Seven days later, the right maxillary incisor was extracted and analyses were performed up to 28 days of the alveolar healing process (35 days after saline or OT administration). Calcium and phosphorus plasma concentrations did not differ between the groups. The plasma biochemical bone formations markers, alkaline phosphatase (ALP) and osteocalcin were significantly higher in the treated group. Histomorphometric analyses confirmed bone formation as the treated group presented the highest mean value of post-extraction bone formation. Tartrate-resistant acid phosphatase (TRAP) was significantly reduced in the treated group indicating an anti-resorptive effect of OT. Immunohistochemistry reactions performed in order to identify the presence of osteocalcin and TRAP in the bone cells of the dental socket confirmed these outcomes. OT was found to promote bone formation and to inhibit bone resorption in old acyclic female rats during the alveolar healing process. Published by Elsevier Ltd.

Experiments using female mice and bats have demonstrated that tritium-labeled 17β-estradiol ( 3 H-E 2 ) can be absorbed via cutaneous and intranasal routes and distributed to reproductive and neural tissues. Radioactivity has also been measured in tissues of untreated females after 48h cohabitation with 3 H-E 2 injected males. The present study was designed to quantify steroid transfer among female bats. Radioactive quantification via liquid scintillation counting revealed absorption of tritium-labeled progesterone ( 3 H-P 4 ) in adult females 1h after cutaneous and intranasal application (10μCi). Subsequently, pairs of mature females were each housed for 48h with a single mature female that had been administered 3 H-P 4 (50μCi) via intraperitoneal injection. Radioactivity was observed in all collected tissues of all non-injected females at levels significantly greater than the control group. Following the same paradigm, radioactivity was not observed in the tissues of untreated female bats that were housed with stimulus females treated with 3 H-E 2 (50μCi). Enzyme immunoassays revealed measurable levels of unconjugated progesterone and estradiol in the urine of female bats, suggesting urine as a vector for steroid transfer. Given that bats of this species live in predominantly female roosts in very close contact, progesterone transfer among individuals is likely to occur in natural roosts. Copyright © 2017 Elsevier Inc.

Sensory feedback is an important component of any behavior, with each instance influencing subsequent activity. Female sexual receptivity is mediated both by the steroid hormone milieu and interaction with the male. We tested the influence of repeated mating on the level of sexual receptivity in ovariectomized rats treated with estradiol benzoate (EB) once every fourth day to mimic the normal phasic changes of circulating estradiol. Females were divided into two groups: naïve, which were tested for lordosis behavior once, and experienced rats, which were tested for lordosis after each EB injection. To monitor the effect of mating, the number of neurons expressing the immediate early gene activity-regulated cytoskeleton-associated protein (Arc) were counted in the mediobasal hypothalamus. Females were unreceptive following the first EB treatment, but the mating induced Arc expression. In naïve rats, each subsequent EB injection increased the levels of sexual receptivity. This ramping was not observed in experienced rats, which achieved only a moderate level of sexual receptivity. However, experienced females treated with EB and progesterone were maximally receptive and did not have Arc expression. To test whether the expression of Arc attenuated lordosis, Arc antisense oligodeoxynucleotides (asODN) were microinjected into experienced females' arcuate nuclei. Arc expression was attenuated, and the experienced EB-treated females achieved maximal sexual receptivity. These results demonstrate that Arc expression in the hypothalamus might influence future sexual receptivity and provides evidence of learning in the arcuate nucleus. The loss of Arc results in unrestrained sexual receptivity. © 2014 Wiley Periodicals, Inc.

Alumina nanoparticles (AlNP) have been shown to accumulate in organs and penetrate biological barriers which lead to toxic effects in many organ systems. However, it is not known whether AlNP exposure to female mice during pregnancy can affect the development of the central nervous system or induce neurodevelopmental toxicity in the offspring. The present study aims to examine the effect of AlNP on neurodevelopment and associated underlying mechanism. ICR strain adult female mice were randomly divided into four groups, which were treated with normal saline (control), 10 μm particle size of alumina (bulk-Al), and 50 and 13 nm AlNP during entire pregnancy period. Aluminum contents in the hippocampus of newborns were measured and neurodevelopmental behaviors were tracked in the offspring from birth to 1 month of age. Furthermore, oxidative stress and neurotransmitter levels were measured in the cerebral cortex of the adolescents. Our results showed that aluminum contents in the hippocampus of newborns in AlNP-treated groups were significantly higher than those in bulk-Al and controls. Moreover, the offspring delivered by AlNP-treated female mice displayed stunted neurodevelopmental behaviors. Finally, the offspring of AlNP-treated mice demonstrated significantly increased anxiety-like behavior with impaired learning and memory performance at 1 month of age. The underlying mechanism could be related to increased oxidative stress and decreased neurotransmitter levels in the cerebral cortex. We therefore conclude that AlNP exposure of female mice during pregnancy can induce neurodevelopmental toxicity in offspring.

In certain populations, female Japanese macaques (Macaca fuscata) mount both males and females. Vasey (2007) proposed that female-female sexual mounting in Japanese macaques may be a neutral evolutionary by-product of a purported adaptation, namely, female-male mounting. In this study, we aim to further examine the proposed link between female-male and female-female mounting in Japanese macaques by comparing the structural characteristics that define both forms of mounting. We do so using Eshkol-Wachman Movement Notation (EWMN), a globographic reference system that can be used to describe the position of body segments. No significant differences were observed in the female mounters' positioning of eight different body segments (i.e., lower torso, mid-torso, upper torso, upper arm, lower arm, upper leg, lower leg, and foot) during female-male and female-female mounting. This finding lends support to the conclusion that female-female and female-male mounting are structurally, and thus, evolutionarily, related. Copyright © 2015 Elsevier B.V. All rights reserved.

Our goal was to compare the survival advantage of tamoxifen (TAM) and aromatase inhibitor (AI) in female (FBC) and male breast cancer (MBC). We performed a retrospective study of 2785 FBC and 257 MBC patients treated with hormonal therapy. The median follow-up was 106 months (range 3-151 months) and 42 months (range 2-115 months) for FBC and MBC, respectively. The patients were divided into two groups according to the hormonal therapy used: TAM-treated and AI-treated. MBC was characterized by older age, advanced tumor stage, and higher rate of lymph node metastases, in comparison with FBC. Matching analysis was performed using six prognostic criteria: patient age, tumor stage, tumor grade, lymph node status, human epidermal growth factor receptor (HER2) status, and administration of chemotherapy. The female and male patients were matched 2:1. In this analysis, 316 women and 158 men treated with TAM, and 60 women and 30 men treated with AI, were included. The overall survival (OS) was estimated by the Kaplan-Meier method and was compared between FBC and MBC. TAM-treated FBC and MBC patients had similar 5-year OS, 85.1 and 89.2%, respectively (p = 0.972). Notably, FBC patients treated with AI had significantly greater 5-year OS (85.0%) in comparison with AI-treated MBC patients (5-year OS of 73.3%; p = 0.028). The OS of TAM-treated patients with MBC was similar to the OS of TAM-treated FBC patients, whereas AI treatment is associated with poorer survival of MBC patients.

Breast cancer risk is still an important topic regarding hormone therapy as well as oral contraception. Evidence that progestogens may play a crucial role is accumulating. Progesterone receptor membrane component 1 (PGRMC1) expressed in breast cancer may be important in tumorigenesis and thus may increase breast cancer risk. The aim of this project was to investigate the influence of different estradiol (E2) concentrations and the addition of two progestogens on MCF-7 breast cancer cells overexpressing PGRMC1. MCF-7 cells were stably transfected with PGRMC1 expression plasmid (MCF-7/PGRMC1-3HA [WT-12]). To test the effects of E2 and progestogens on cell proliferation, MCF-7 and WT-12 cells were stimulated with different concentrations of E2 (10 and 10 M) alone and in combination with progesterone and medroxyprogesterone acetate (each 10 M). E2 elicited a concentration-dependent proliferative effect on both cell lines, which was much more pronounced in WT-12 cells (50% vs 200%). This effect could be completely abrogated by the addition of the E2 antagonist fulvestrant. Addition of progesterone had no influence on the E2-induced effect, whereas medroxy-progesterone acetate enhanced the E2-induced effect at a low E2 concentration, which was, again, more pronounced in the WT-12 cells. The figures were between 20% and 40% in MCF-7 and between 60% and 250% in WT-12 cells. Overexpression of PGRMC1 sensitizes the proliferative response of the MCF-7 breast cancer cell line to estradiol. The effect of progestogens on breast cancer tumorigenesis may depend on the specific progestogen used for hormone therapy or oral contraception.

Full Text Available Introduction: Female urethral stricture is an underdiagnosed and overlooked cause of female bladder outlet obstruction. The possible etiologies may be infection, prior dilation, difficult catheterization with subsequent fibrosis, urethral surgery, trauma, or idiopathic. We present our technique and results of dorsal onlay full thickness vaginal graft urethroplasty for female urethral stricture. Materials and Methods: A retrospective review was performed on 16 female patients with mid-urethral stricture who underwent dorsal onlay vaginal graft urethroplasty from January 2007 to June 2011.Of these, 13 patients had previously undergone multiple Hegar dilatations, three had previous internal urethrotomies. The preoperative work up included detailed voiding history, local examination, uroflowmetry, calibration, and micturating cystourethrogram. Results: All patients had mid-urethral stricture. Mean age was 47.5 years. Mean Q max improved from 6.2 to 27.6 ml/s. Mean residual volume decreased from 160 to 20 ml. Mean duration of follow-up was 24.5 months (6 months to 3 years. Only one patient required self-calibration for 6 months after which her stricture stabilized. None of the patient was incontinent. Conclusion: Dorsal vaginal onlay graft urethroplasty could be considered as an effective way to treat female urethral stricture.

Full Text Available Abstract Background Lepidium meyenii, known as Maca, grows exclusively in the Peruvian Andes over 4000 m altitude. It has been used traditionally to increase fertility. Previous scientific studies have demonstrated that Maca increases spermatogenesis and epididymal sperm count. The present study was aimed to investigate the effects of Maca on several fertility parameters of female mice at reproductive age. Methods Adult female Balb/C mice were divided at random into three main groups: i Reproductive indexes group, ii Implantation sites group and iii Assessment of uterine weight in ovariectomized mice. Animals received an aqueous extract of lyophilized Yellow Maca (1 g/Kg BW or vehicle orally as treatment. In the fertility indexes study, animals received the treatment before, during and after gestation. The fertility index, gestation index, post-natal viability index, weaning viability index and sex ratio were calculated. Sexual maturation was evaluated in the female pups by the vaginal opening (VO day. In the implantation study, females were checked for implantation sites at gestation day 7 and the embryos were counted. In ovariectomized mice, the uterine weight was recorded at the end of treatment. Results Implantation sites were similar in mice treated with Maca and in controls. All reproductive indexes were similar in both groups of treatment. The number of pups per dam at birth and at postnatal day 4 was significantly higher in the group treated with Maca. VO day occurred earlier as litter size was smaller. Maca did not affect VO day. In ovariectomized mice, the treatment with Maca increased significantly the uterine weights in comparison to their respective control group. Conclusion Administration of aqueous extract of Yellow Maca to adult female mice increases the litter size. Moreover, this treatment increases the uterine weight in ovariectomized animals. Our study confirms for the first time some of the traditional uses of Maca to

Exposure to testosterone early in life may contribute to sex differences and pubertal changes in risk for eating pathology (i.e., females > males, after pubertal onset). Specifically, perinatal testosterone permanently alters brain structure/function and drives the masculinization of several sex-differentiated behaviors. However, the effects of perinatal testosterone are often not evident until puberty when increases in gonadal hormones activate the expression of sex typical behavior, including eating behaviors (e.g., chow intake; saccharin preference) in rodents. Despite perinatal testosterone's masculinizing effects on general feeding behavior, it remains unknown if perinatal testosterone exposure contributes to sex differences in pathological eating. The current study addressed this gap by examining whether perinatal testosterone exposure decreases risk for binge eating proneness after pubertal onset in male and female rats. Sprague-Dawley rats (n = 40 oil-treated control females; n = 39 testosterone-treated females; n = 40 oil-treated control males) were followed longitudinally across pre-to-early puberty, mid-to-late puberty, and adulthood. The binge eating prone (BEP)/binge eating resistant (BER) rodent model was used to identify individual differences in binge eating proneness across the dimensional spectrum. As expected, testosterone-treated females and control males showed masculinized (i.e., lower) risk for binge eating as compared to control females, but only after midpuberty. These animal data are significant in suggesting that perinatal testosterone exposure may protect against binge eating and underlie sex differences in binge eating prevalence during and after puberty.

Athletic pubalgia is typically associated with male athletes participating in contact sports and less frequently with females. Endoscopic surgery may fully treat the patient with athletic pubalgia. To perform an outcomes analysis of magnetic resonance imaging (MRI) and endoscopic surgery in female patients with athletic pubalgia. Cohort study; Level of evidence, 3. Fifteen physically active female patients (mean age, 37 years) with athletic pubalgia were treated surgically via placement of total extraperitoneal endoscopic polypropylene mesh behind the injured groin area. The presence of preoperative bone marrow edema (BME) at the pubic symphysis seen on MRI was graded from 0 to 3 and correlated with pain scores after surgery. The outcome measures were pre- and postoperative pain scores and recovery to daily activity between 1 and 12 months after surgery. Results were compared with previously published scores from male athletes (n = 30). With the exception of lower body mass index, the females with (n = 8) and without (n = 7) pubic BME had similar patient characteristics to the corresponding males. Mean inguinal pain scores (0-10) before surgical treatment were greater in females than males (during exercise, 7.8 ± 1.1 vs 6.9 ± 1.1; P = .0131). One month after surgery, mean pain scores for females were still greater compared with males (2.9 ± 1.7 vs 1.3 ± 1.6; P = .0034). Compared with female athletes with normal MRI, pubic BME was related to increased mean preoperative pain scores (8.13 ± 0.99 vs 6.43 ± 1.2; P = .0122). After 1 year, surgical outcomes were excellent or good in 47% of women. Endoscopic surgery was helpful in half of the females with athletic pubalgia in this study. The presence of pubic BME may predict slightly prolonged recovery from surgery.

Abstract Objectives We aimed at assessing whether differences among males and females in carpal tunnel syndrome (CTS) epidemiology might be attributable to segregation with respect to occupational biomechanical exposures or differential access to care by sex. Methods We analysed surgically treated cases of CTS occurring among non-manual workers in Tuscany between 1997 and 2000. We conducted a Monte Carlo simulation to estimate the difference in occupational biomechanical exposures between males and females necessary to explain the observed incidence rate ratios. We also accounted for the sex-specific probability of receiving surgery after the diagnosis of CTS, as women were reported to be more likely to undergo surgery in a subset of our study population. We quantified the hypothetical biomechanical overload through the hand activity level (HAL) metric proposed by the American Conference of Governmental Industrial Hygienists. To quantify the effect of HAL on CTS risk, we assumed a prior distribution based on findings from two large cohort studies of industrial workers. Results After adjustment for the probability of receiving surgery, women showed a 4-fold incidence of CTS as compared with men. To explain this association among non-manual workers, women should have an average value of HAL at least 5 points higher. Conclusions Our analysis does not support the hypothesis that the difference in CTS incidence between males and females is entirely attributable to occupational risk factors or to differential access to surgery. The causal pathway between sex and CTS might include more determinants such as hormonal factors, anthropometric characteristics, and non-occupational exposure to biomechanical overload (e.g. household tasks).

Arcuate nucleus (ARN) γ-aminobutyric acid (GABA) neurons are implicated in many critical homeostatic mechanisms, from food intake to fertility. To determine the functional relevance of ARN GABA neurons, it is essential to define the neurotransmitters co-expressed with and potentially co-released from ARN GABA neurons. The present study investigated the expression of markers of specific signaling molecules by ARN GABA neurons in brain sections from male, female, and, in some cases, prenatally androgen-treated (PNA) female, vesicular GABA transporter (VGaT)-ires-Cre/tdTomato reporter mice. Immunofluorescence for kisspeptin, β-endorphin, neuropeptide Y (NPY), tyrosine hydroxylase (TH) and neuronal nitric oxide synthase (nNOS) was detected by confocal microscopy, and co-localization with tdTomato VGaT reporter expression throughout the ARN was quantified. GABA neurons rarely co-localized with kisspeptin (95%) co-localized with VGaT across groups. Both TH and nNOS labeling was co-localized with ∼10% of ARN GABA neurons. The proportion of TH neurons co-localized with VGaT was significantly greater in males than either control or PNA females, and the proportion of nNOS neurons co-localizing VGaT was higher in control and PNA females compared with males. These data highlight NPY as a significant subpopulation of ARN GABA neurons, demonstrate no significant impact of PNA on signal co-expression, and, for the first time, show sexually dimorphic co-expression patterns of TH and nNOS with ARN GABA neurons. © 2016 S.

The taxane chemotherapeutic paclitaxel frequently produces peripheral neuropathy in humans. Rodent models to investigate mechanisms and treatments are largely restricted to male rats, whereas female mouse studies are lacking. We characterized a range of paclitaxel doses on cold and mechanical allodynia in male and female C57Bl/6 mice. Because the nonpsycho-active phytocannabinoid cannabidiol attenuates other forms of neuropathic pain, we assessed its effect on paclitaxel-induced allodynia. Pa...

Full Text Available Quan Q Dinh, Rodney SinclairDepartment of Dermatology, St Vincent’s Hospital, Fitzroy, Victoria, AustraliaAbstract: Fewer than 45% of women go through life with a full head of hair. Female pattern hair loss is the commonest cause of hair loss in women and prevalence increases with advancing age. Affected women may experience psychological distress and impaired social functioning. In most cases the diagnosis can be made clinically and the condition treated medically. While many women using oral antiandrogens and topical minoxidil will regrow some hair, early diagnosis and initiation of treatment is desirable as these treatments are more effective at arresting progression of hair loss than stimulating regrowth. Adjunctive nonpharmacological treatment modalities such as counseling, cosmetic camouflage and hair transplantation are important measures for some patients. The histology of female pattern hair loss is identical to that of male androgenetic alopecia. While the clinical pattern of the hair loss differs between men, the response to oral antiandrogens suggests that female pattern hair loss is an androgen dependant condition, at least in the majority of cases. Female pattern hair loss is a chronic progressive condition. All treatments need to be continued to maintain the effect. An initial therapeutic response often takes 12 or even 24 months. Given this delay, monitoring for treatment effect through clinical photography or standardized clinical severity scales is helpful.Keywords: female pattern hair loss, androgenetic alopecia

Full Text Available Abstract Women with hereditary angioedema (HAE are more likely to be symptomatic that men. Hormonal factors (puberty, contraception, pregnancy,.... play a significant role in the precipitation or worsening of the condition in women. So, combined contraceptive pills are not indicated and progestogen pill must be preferred. During pregnancy, attack rate can increase (38-48% of women. C1Inhibitor concentrate and tranexamic acid can be used during pregnancy. Attenuated androgens for long term prophylaxis are effective but side effects appear more often in female patients. These side effects are dose dependant and can be attenuated by titrating the dose down the lowest effective level.

Achieving the recommended serum urate levels of less than 6.0 mg/dL is difficult in elderly (65 years of age or older patients with renal impairment. Xanthine oxidase inhibitors allopurinol and febuxostat are used for this purpose. Although febuxostat had been shown to be efficacious in elderly patients, its safety and efficacy in elderly female patients with hyper­uricemia remain unclear.Objective: The aim of this study was to assess the efficacy and safety of febuxostat in elderly female patients.Methods: We studied a retrospective cohort study. The study included elderly Japanese patients (65 years of age or older who were treated with febuxostat at Fujita Health University Hospital from January 2012 to December 2013. The treatment goal was defined as achievement of serum urate levels of 6.0 mg/dL or lower within 16 weeks; this was the primary endpoint in the present study. Adverse events of febuxostat were defined as more than twofold increases in Common Terminology Criteria for adverse events scores from baseline. Results: We evaluated 82 patients treated with febuxostat during the observation period and classified them into male (n=53 and female (n=29 groups. The mean time to achievement of the treatment goal was significantly shorter in the female group (53 days than in the male group (71 days. There were no significant differences in adverse events between the 2 groups.Conclusion: Our

Genomic instability can be produced by ionising radiation, so-called radiation-induced genomic instability, and chemical mutagens. Radiation-induced genomic instability occurs in both germinal and somatic cells and also in the offspring of irradiated individuals, and it is characterised by genetic changes including chromosomal rearrangements. The majority of studies of trans-generational, radiation-induced genomic instability have been described in the male germ line, whereas the authors who have chosen the female as a model are scarce. The aim of this work is to find out the radiation-induced effects in the foetal offspring of X-ray-treated female rats and, at the same time, the possible impact of this radiation-induced genomic instability on the action of a chemical mutagen. In order to achieve both goals, the quantity and quality of chromosomal damage were analysed. In order to detect trans-generational genomic instability, a total of 4806 metaphases from foetal tissues from the foetal offspring of X-irradiated female rats (5 Gy, acute dose) were analysed. The study's results showed that there is radiation-induced genomic instability: the number of aberrant metaphases and the breaks per total metaphases studied increased and were found to be statistically significant (p ≤ 0.05), with regard to the control group. In order to identify how this trans-generational, radiation-induced chromosomal instability could influence the chromosomal behaviour of the offspring of irradiated rat females in front of a chemical agent (aphidicolin), a total of 2481 metaphases were studied. The observed results showed that there is an enhancement of the action of the chemical agent: chromosomal breaks per aberrant metaphases show significant differences (p ≤ 0.05) in the X-ray- and aphidicolin-treated group as regards the aphidicolin-treated group. In conclusion, our findings indicate that there is trans-generational, radiation-induced chromosomal instability in the foetal cells

Purpose: Subsequent malignant neoplasms (SMNs) are a dominant cause of morbidity and mortality in children treated for Hodgkin's disease (HD). We evaluated select demographic and therapeutic factors associated with SMNs, specifically gender and radiation dose. Methods and Materials: A total of 930 children treated for HD at five institutions between 1960 and 1990 were studied. Mean age at diagnosis was 13.6 years, and mean follow-up was 16.8 years (maximum, 39.4 years). Treatment included radiation alone (43%), chemotherapy alone (9%), or both (48%). Results: We found that SMNs occurred in 102 (11%) patients, with a 25-year actuarial rate of 19%. With 15,154 patient years of follow-up, only 7.18 cancers were expected (standardized incidence ratio [SIR] = 14.2; absolute excess risk [AER] = 63 cases/10,000 years). The SIR for female subjects, 19.93, was significantly greater than for males, 8.41 (p < 0.0001). After excluding breast cancer, the SIR for female patients was 15.4, still significantly greater than for male patients (p = 0.0012). Increasing radiation dose was associated with an increasing SIR (p = 0.0085). On univariate analysis, an increased risk was associated with female gender, increasing radiation dose, and age at treatment (12-16 years). Using logistic regression, mantle radiation dose increased risk, and this was 2.5-fold for female patients treated with more than 35 Gy primarily because of breast cancer. Conclusions: Survivors of childhood HD are at risk for SMNs, and this risk is greater for female individuals even after accounting for breast cancer. Although SMNs occur in the absence of radiation therapy, the risk increases with RT dose

Background. Knowledge about female sexual problems after pre- or postoperative (chemo-)radiotherapy and radical resection of rectal cancer is limited. The aim of this study was to compare self-rated sexual functioning in women treated with or without radiotherapy (RT+ vs. RT?), at least two years after surgery for rectal cancer. Methods and materials. Female patients diagnosed from 1993 to 2003 were identified from a national database, the Norwegian Rectal Cancer Registry. Eligible patients were without recurrence or metastases at the time of the study. The Sexual function and Vaginal Changes Questionnaire (SVQ) was used to measure sexual functioning. Results. Questionnaires were returned from 172 of 332 invited and eligible women (52%). The mean age was 65 years (range 42-79) and the time since surgery for rectal cancer was 4.5 years (range 2.6-12.4). Sexual interest was not significantly impaired in RT+ (n=62) compared to RT? (n=110) women. RT+ women reported more vaginal problems in terms of vaginal dryness (50% vs. 24%), dyspareunia (35% vs. 11%) and reduced vaginal dimension (35% vs. 6%) compared with RT? patients; however, they did not have significantly more worries about their sex life. Conclusion. An increased risk of dyspareunia and vaginal dryness was observed in women following surgery combined with (chemo-)radiotherapy compared with women treated with surgery alone. Further research is required to determine the effect of adjuvant therapy on female sexual function

Simultaneous perineal ultrasound and vaginal pressure measurement prove the action of electrical pudendal nerve stimulation in treating female stress incontinence.

Study Type - Diagnostic (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Pelvic floor muscle training (PFMT) and transvaginal electrical stimulation (TES) are two commonly used forms of conservative treatment for stress urinary incontinence (SUI). PFMT may build up the structural support of the pelvis, but many SUI patients are unable to perform PFMT effectively and its primary disadvantage is lack of long-term patient compliance. TES is a passive treatment that produces PFM contraction and patient compliance with it is good; however, its effect is not as good as that of PFMT when performed correctly. Electrical pudendal nerve stimulation (EPNS) combines the advantages of PFMT and TES and incorporates the technique of deep insertion of long needles. In this study, simultaneous perineal ultrasound and vaginal pressure measurement prove that EPNS can contract the PFM and simulate PFMT. It is shown that EPNS is an alternative therapy for female SUI patients who fail PFMT and TES and the therapy can also be used for severe SUI. • To prove that electrical pudendal nerve stimulation (EPNS) can contract the pelvic floor muscles (PFM) and simulate pelvic floor muscle training (PFMT). • To show that EPNS is an alternative therapy for female stress urinary incontinence (SUI) that does not respond effectively to PFMT and transvaginal electrical stimulation (TES). • Thirty-five female patients with SUI who did not respond effectively to PFMT and TES (group I) were enrolled and 60 other female patients with SUI were allocated to group II (30 patients) and group III (30 patients). • Long needles were deeply inserted into four sacral points and electrified to stimulate the pudendal nerves. Group I and group II were treated by a doctor skilled in performing EPNS and group III, by a doctor unskilled in performing EPNS. • When EPNS was performed in group I, perineal ultrasonographic PFM movements, vaginal pressure (VP) and PFM

According to victimization surveys, the percentage of females among child abusers is much higher than 2 or 5% as usually reported in the devoted literature. The under-estimated percentage of child sexual abuses committed by females would result from the dissimulation of sexual acts within nursing care, a gender bias in favor of women among child protection system professionals and low disclosures. Sexual abuses committed by females are often more harmful for children than sexual abuses committed by males. Although a few female child abusers suffers from psychiatric disorders, most of them are psychologically and emotionally dependent from a man or have psychopathic, manipulative and sometimes sadistic personality traits. Female child abusers are a heterogeneous population either acting under the influence of a man or initiating actively the offending for pedophile or financial motivations. Deconstructing the persistent myths about female child abusers is necessary to better identify these women, treat them and prevent relapse. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Sex-specific substance abuse treatment for female healthcare professionals: implications.

Gender plays a significant role in the development and treatment of substance abuse disorders. Sex-specific treatment for girls and women has recurrently proven more effective, with better outcomes than traditional treatment. Research on impaired healthcare professionals (HCPs) has largely focused on men, garnering little attention for women and sex differences. With the increasing numbers of female HCPs, it is imperative to identify potential sex differences that may have implications for treatment. Our study compared a convenience sample of male and female HCPs with substance abuse disorders treated in an outpatient program to identify sex differences that may have implications for treatment. Our sample consisted of 96 HCPs (54 men, 42 women) and 17 non-healthcare professional (N-HCP) women. All of the participants were evaluated using the program's clinical interview and the Personality Assessment Inventory (PAI). Chart review data contained categorical variables, qualitative variables, diagnoses, and psychological test scores. A second analysis was conducted through two separate comparisons: the PAI results of comparing impaired female HCPs with impaired male HCPs and the PAI results of comparing impaired female HCPs with impaired female N-HCPs. Statistically significant differences indicated more male participants received prior treatment and more intensive treatment than female participants. More female subjects reported being diagnosed as having a comorbid psychiatric condition and taking psychotropic medications. Several statistically significant differences in the PAI scores were found. Among female HCPs, elevations were found in anxiety, depression, paranoia, and borderline personality disorder. Substantive differences, although not statistically significant, were elevations in somatic complaints and anxiety disorders in female HCPs. In the comparison of female HCPs and N-HCPs, the only statistically significant difference was the significantly higher

Full Text Available The purpose of this study was to assess differences in the management techniques used by Israeli female and male pediatric dentists. All 112 participants of the meeting of the Israeli Society of Dentistry for Children that was held in February 1999 received a questionnaire which sought information regarding age, sex, behavioral and pharmacological methods used to treat children, having a course in nitrous oxide, general anesthesia, and feelings towards pediatric patients. No differences between female and male dentists were found regarding most management techniques. The majority of dentists used tell-show-do, and gave presents at the end of the appointments. Hypnosis was the least used technique. Papoose board was more prevalent among male dentists than among female dentists. Most dentists reported having the parents present during treatment, and more male dentists used their assistance when restraint was needed. General anesthesia was significantly more prevalent among males than among females (p = 0.01. One-third of the dentists reported feeling aggression toward the pediatric patient. Although not statistically significant, more female dentists reported about feeling aggression than male dentists. Most dentists felt authority towards the pediatric patient. Our findings imply that female and male dentists use similar management techniques when treating children.

Neurogenesis in the olfactory bulb induced by paced mating in the female rat is opioid dependent.

Directory of Open Access Journals (Sweden)

Marianela Santoyo-Zedillo

Full Text Available The possibility to control the rate of sexual stimulation that the female rat receives during a mating encounter (pacing increases the number of newborn neurons that reach the granular layer of the accessory olfactory bulb (AOB. If females mate repeatedly, the increase in the number of neurons is observed in other regions of the AOB and in the main olfactory bulb (MOB. It has also been shown that paced mating induces a reward state mediated by opioids. There is also evidence that opioids modulate neurogenesis. In the present study, we evaluated whether the opioid receptor antagonist naloxone (NX could reduce the increase in neurogenesis in the AOB induced by paced mating. Ovariectomized female rats were randomly divided in 5 different groups: 1 Control (not mated treated with saline, 2 control (not mated treated with naloxone, 3 females that mated without controlling the sexual interaction (no-pacing, 4 females injected with saline before pacing the sexual interaction and 5 females injected with NX before a paced mating session. We found, as previously described, that paced mating induced a higher number of new cells in the granular layer of the AOB. The administration of NX before paced mating, blocked the increase in the number of newborn cells and prevented these cells from differentiating into neurons. These data suggest that opioid peptides play a fundamental role in the neurogenesis induced by paced mating in female rats.

Hall, P E

1998-08-01

Once-a-month injectable contraceptives containing a progestogen and an estrogen have been developed that disrupt vaginal bleeding patterns less than the widely used progestogen-only preparations. Pharmacokinetic studies were undertaken of dosages and ratios of the progestogens and the respective estrogens. In Phase III clinical trials, annual pregnancy rates were below 0.4% for Mesigyna (norethisterone enanthate/estradiol valerate, Schering AG, Berlin, Germany) and below 0.2% for Cyclofem (MPA/E2C) (medroxyprogesterone acetate/estradiol cypionate, Aplicaciones Farmaceuticas, SA, Mexico and PT Tunggal, Indonesia). More than two-thirds of women had predictable, regular cycles, and discontinuation due to bleeding-related problems occurred less than half as often as with progestogen-only injectables. With MPA/E2C, return to fertility is similar to that observed with other hormonal or intrauterine methods, and both products have little effect on lipids or hemostasis. Introductory trials of MPA/E2C in 12000 women with 100000 woman-months of experience confirmed the high efficacy of the product in routine use. The use of MPA/E2C in a non-reusable injection device, Uniject (Becton Dickinson, Franklin Lakes, NJ) is discussed. Once-a-month hormonal contraceptives have been shown to provide a safe contraceptive option for all women and an alternative for women who wish to use injectable formulations that cause less disruption in vaginal bleeding and minimal side effects.

Impact of Radiotherapy on Fertility, Pregnancy, and Neonatal Outcomes in Female Cancer Patients

Purpose: Radiation has many potential long-term effects on cancer survivors. Female cancer patients may experience decreased fertility depending on the site irradiated. Oncologists should be aware of these consequences and discuss options for fertility preservation before initiating therapy. Methods and Materials: A comprehensive review of the existing literature was conducted. Studies reporting the outcomes for female patients treated with cranio-spinal, abdominal, or pelvic radiation reporting fertility, pregnancy, or neonatal-related outcomes were reviewed. Results: Cranio-spinal irradiation elicited significant hormonal changes in women that affected their ability to become pregnant later in life. Women treated with abdomino-pelvic radiation have an increased rate of uterine dysfunction leading to miscarriage, preterm labor, low birth weight, and placental abnormalities. Early menopause results from low-dose ovarian radiation. Ovarian transposition may decrease the rates of ovarian dysfunction. Conclusions: There is a dose-dependent relationship between ovarian radiation therapy (RT) and premature menopause. Patients treated with RT must be aware of the impact of treatment on fertility and explore appropriate options.

Male sexual harassment alters female social behaviour towards other females.

Darden, Safi K; Watts, Lauren

2012-04-23

Male harassment of females to gain mating opportunities is a consequence of an evolutionary conflict of interest between the sexes over reproduction and is common among sexually reproducing species. Male Trinidadian guppies Poecilia reticulata spend a large proportion of their time harassing females for copulations and their presence in female social groups has been shown to disrupt female-female social networks and the propensity for females to develop social recognition based on familiarity. In this study, we investigate the behavioural mechanisms that may lead to this disruption of female sociality. Using two experiments, we test the hypothesis that male presence will directly affect social behaviours expressed by females towards other females in the population. In experiment one, we tested for an effect of male presence on female shoaling behaviour and found that, in the presence of a free-swimming male guppy, females spent shorter amounts of time with other females than when in the presence of a free-swimming female guppy. In experiment two, we tested for an effect of male presence on the incidence of aggressive behaviour among female guppies. When males were present in a shoal, females exhibited increased levels of overall aggression towards other females compared with female only shoals. Our work provides direct evidence that the presence of sexually harassing males alters female-female social behaviour, an effect that we expect will be recurrent across taxonomic groups.

Sogatella furcifera Horváth (Hemiptera: Delphacidae), is a major migratory pest of rice crops in Asia. The ultrastructure of the flight muscle directly affects the flight ability of insects. The ultrastructure of the flight muscle of some insects can be affected by insecticides. However, the ultrastructure of the flight muscle of S. furcifera and the effect of insecticides on the flight muscle of S. furcifera are not well understood. The present study was conducted to determine the effect of the insecticide dinotefuran on the ultrastructure of the flight muscle of S. furcifera females. In this study, the cross-sectional area and the diameter of the myofibril cross-sections of dinotefuran-treated S. furcifera females increased with the number of days after emergence (DAE), and they were higher than in untreated females. The sarcomere length of myofibrils increased with the number of DAE, and it differed from that of the untreated females. On the first day after emergence, the higher the concentration of dinotefuran, the smaller was the extent of decrease. On the third day after emergence, the higher the concentration of dinotefuran, the larger was the extent of enhancement. For the percentage of mitochondria, those of LC10 and LC20 dinotefuran-treated S. furcifera females increased with the number of DAE and were higher than in untreated females. LC10 dinotefuran-treated S. furcifera females exhibited the largest increase. Thus, our results suggest that the flight ability of S. furcifera increased with time. Some concentrations of dinotefuran can enhance the flight capacity of S. furcifera. © The Authors 2017. Published by Oxford University Press on behalf of Entomological Society of America.

Fourteen female patients with primary urethral carcinoma were treated at the Manitoba Cancer Foundation in the last twenty-nine years. The relationship of natural history to the stage, location, and therapeutic modality has been reviewed. A higher stage and length of urethral involvement affected prognosis negatively, whereas lower stage had a positive prognostic effect and location of tumor had no prognostic influence. Two patients with Stage C, who failed to received inguinal node radiotherapy, died of disease recurring in the inguinal area. Patients who received inguinal radiation (3 patients Stages B, C, and D1) had no regional recurrence. It is suggested that, for all female urethral carcinoma, bilateral ilioinguinal nodes be included in the radiation field. For radical treatment, iridium 192 insertion in combination with external beam treatment is recommended

The aim of the present work was to determine whether treatment with melatonin modifies the reproductive response of female goats experiencing increasing or decreasing body weight (BW)/body condition score (BCS) when introduced to bucks displaying springtime sexual activity. During natural anoestrus, 53 does were isolated from bucks for a period of 42days and distributed into two groups: 1) low BW/low BCS animals (N=24) (LLg group), which were fed 1.9 times their maintenance requirements so they would experience increasing BW and BCS; and 2) high BW/high BCS animals (N=29) (HHl group), which were fed 0.4 times their maintenance requirements so they would experience decreasing BW and BCS. Half of each group was treated, or not, with melatonin (LLg+Mel N=12, HHl+Mel N=15, LLg-Mel N=12 and HHl-Mel N=14). On 6th May they were introduced to six males, showing natural sexual activity, fitted with marking harnesses (thus permitting the detection of oestrous activity). The ovulation rate was assessed by transrectal ultrasonography and confirmed via the plasma progesterone concentration (measured twice per week in blood samples). Plasma glucose, IGF-1 and non-esterified fatty acid concentrations were also determined, along with the conception rate, fertility, prolificacy and productivity of the does. LH concentrations and LH pulsatility were also recorded in the hours around introduction to the males. 'Oestrous plus ovulation' was observed only in does treated with melatonin. A higher conception rate and greater fertility and productivity were observed among the LLg+Mel does. These females showed higher glucose and IGF-1 concentrations after the introduction of the males. LH concentrations increased after male introduction independent of all other conditions. In conclusion, the present results show that treatment with melatonin does not enhance reproductive performance in does experiencing decreasing BW/BCS, but can improve it when does are experiencing increasing BW

Objective Because binge eating and emotional eating vary through the menstrual cycle in human females, we investigated cyclic changes in binge-like eating in female rats and their control by estrogens. Method Binge-like eating was elicited by three cycles of 4 days of food restriction and 4 days of free feeding followed by a single frustrative nonreward-stress episode (15 min visual and olfactory exposure to a familiar palatable food) immediately before presentation of the palatable food. Results Intact rats showed binge-like eating during the diestrous and proestrous phases of the ovarian cycle, but not during the estrous (peri-ovulatory) phase. Ovariectomized (OVX) rats not treated with estradiol (E2) displayed binge-like eating, whereas E2-treated OVX rats did not. The procedure did not increase signs of anxiety in an open-field test. OVX rats not treated with E2 that were subjected to food restriction and sacrificed immediately after frustrative nonreward had increased numbers of cells expressing phosphorylated extracellular signal-regulated kinases (ERK) in the central nucleus of the amygdala (CeA), paraventricular nucleus of hypothalamus (PVN), and dorsal and ventral bed nucleus of the stria terminalis (BNST) compared with non-restricted or E2-treated rats. Discussion These data suggest that this female rat model is appropriate for mechanistic studies of some aspects of menstrual-cycle effects on emotional and binge eating in human females, that anxiety is not a sufficient cause of binge-like eating, and that the PVN, CeA and BNST may contribute to information processing underlying binge-like eating.

The effects of kappa opioid receptors (KOR) on motivated behavior are well established based on studies in male rodents, but relatively little is known about the effects of KOR in females. We examined the effects of KOR activation on conditioned place aversion and social interaction in the California mouse (Peromyscus californicus). Important differences were observed in long-term (place aversion) and short-term (social interaction) effects. Females but not males treated with a 2.5mg/kg dose of U50,488 formed a place aversion, whereas males but not females formed a place aversion at the 10 mg/kg dose. In contrast the short term effects of different doses of U50,488 on social interaction behavior were similar in males and females. Acute injection with 10 mg/kg of U50,488 (but not lower doses) reduced social interaction behavior in both males and females. The effects of U50,488 on phosphorylated extracellular signal regulated kinase (pERK) and p38 MAP kinase were cell type and region specific. Higher doses of U50,488 increased the number of pERK neurons in the ventrolateral bed nucleus of the stria terminals in males but not females, a nucleus implicated in male aggressive behavior. In contrast, both males and females treated with U50,488 had more activated p38 cells in the nucleus accumbens shell. Unexpectedly, cells expressing activated p38 co-expressed Iba-1, a widely used microglia marker. In summary we found strong sex differences in the effects of U50,488 on place aversion whereas the acute effects on U50,488 induced similar behavioral effects in males and females. PMID:24445073

The pharmacology of the human female orgasm - its biological and physiological backgrounds.

Levin, Roy J

2014-06-01

The female orgasm has been examined over the years by numerous scientific disciplines yet it still has many secrets to be disclosed. Because its physiology, especially its neurophysiology, is sparingly understood its pharmacology is necessarily limited based mainly on the side effects of drugs. Few published studies have used a placebo group as controls. The paucity of focussed studies is well illustrated by the fact that there still is no approved medication to treat female orgasmic dysfunction. The present brief overview examines the most important aspects of its biology and especially its physiology highlighting the many questions that need answering if we are to have a comprehensive pharmacology of the female orgasm.

Full Text Available MAKNA DIRI ALPHA FEMALE PADA PUSTAKAWAN PEREMPUAN: Membangun Citra Positif Perpustakaan Melalui Kiprah Pustakawan Perempuan Sebagai Alpha Female Abstract The profession of librarians is often associated with women. This can be justified if we refer to data and research results that have been done in several countries. However, many women who work in the library, this does not necessarily describe that library work is a simple and easy job. However, on the contrary, work in the field of library is increasingly complex and demands the competence and mastery of information technology. Moreover, the expectations of some users who demand a fast and quality service. Therefore to answer this problem required a female librarian who has the competence, intelligent and able to become a leader for his group and can show the characteristics as a professional. As for the description of people like this people call it with the term alpha female. With the birth of alpha female figures among female librarians is expected to change the positive image of librarians and library institutions. This is because the female alpha figure in the female librarian is a figure of women who are considered "perfect" are still rare today. Keywords: library, librarian, symbolic interaction, alpha female. Abstrak Profesi pustakawan kerapkali dikaitkan dengan kaum perempuan.

Obstructive sleep apnoea is characterized by chronic intermittent hypoxia (CIH) due to recurrent apnoea. We have developed a rat model of CIH, which shows evidence of impaired respiratory muscle function. In this study, we wished to characterize the ventilatory effects of CIH in conscious male and female animals. Adult male (n=14) and female (n=8) Wistar rats were used. Animals were placed in chambers daily for 8 h with free access to food and water. The gas supply to one half of the chambers alternated between air and nitrogen every 90 s, for 8 h per day, reducing ambient oxygen concentration in the chambers to 5% at the nadir (intermittent hypoxia; n=7 male, n=4 female). Air supplying the other chambers was switched every 90 s to air from a separate source, at the same flow rates, and animals in these chambers served as controls (n=7 male, n=4 female). Ventilatory measurements were made in conscious animals (typically sleeping) after 10 days using whole-body plethysmography. Normoxic ventilation was increased in both male and female CIH-treated rats compared to controls but this did not achieve statistical significance. However, ventilatory drive was increased in CIH-treated rats of both sexes as evidenced by significant increases in mean and peak inspiratory flow. Ventilatory responses to acute hypoxia (F(I)O(2) = 0.10; 6 min) and hyperoxic hypercapnia (F(I)CO(2) = 0.05; 6 min) were unaffected by CIH treatment in male and female rats (P>0.05, ANOVA). We conclude that CIH increases respiratory drive in adult rats. We speculate that this represents a form of neural plasticity that may compensate for respiratory muscle impairment that occurs in this animal model.

Transcriptomics analysis and hormonal changes of male and female neonatal rats treated chronically with a low dose of acrylamide in their drinking water

Full Text Available Acrylamide is known to produce follicular cell tumors of the thyroid in rats. RccHan Wistar rats were exposed in utero to a carcinogenic dose of acrylamide (3 mg/Kg bw/day from gestation day 6 to delivery and then through their drinking water to postnatal day 35. In order to identify potential mechanisms of carcinogenesis in the thyroid glands, we used a transcriptomics approach. Thyroid glands were collected from male pups at 10 PM and female pups at 10 AM or 10 PM in order to establish whether active exposure to acrylamide influenced gene expression patterns or pathways that could be related to carcinogenesis. While all animals exposed to acrylamide showed changes in expected target pathways related to carcinogenesis such as DNA repair, DNA replication, chromosome segregation, among others; animals that were sacrificed while actively drinking acrylamide-laced water during their active period at night showed increased changes in pathways related to oxidative stress, detoxification pathways, metabolism, and activation of checkpoint pathways, among others. In addition, thyroid hormones, triiodothyronine (T3 and thyroxine (T4, were increased in acrylamide-treated rats sampled at night, but not in quiescent animals when compared to controls. The data clearly indicate that time of day for sample collection is critical to identifying molecular pathways that are altered by the exposures. These results suggest that carcinogenesis in the thyroids of acrylamide treated rats may ensue from several different mechanisms such as hormonal changes and oxidative stress and not only from direct genotoxicity, as has been assumed to date.

To confirm gender specific differences in pathologic factors and survival rates of urothelial bladder cancer patients treated with radical cystectomy. We conducted a retrospective monocentric study on 701 patients treated with radical cystectomy and pelvic lymphadenectomy for muscle invasive bladder cancer. Impact of gender on recurrence rate, specific and non-specific mortality rate were evaluated using Cox regression models in univariate and multivariate analysis. We collected data on 553 males (78.9%) and 148 females (21.1%) between 1998 and 2011. Both groups were comparable at inclusion regarding age, pathologic stage, nodal status and lymphovascular invasion. Mean follow-up time was 45 months (interquartile 23-73) and by that time, 163 patients (23.3%) had recurrence of their tumor and 127 (18.1%) died from their disease. In multivariable Cox regression analyses, female gender was independently associated with disease recurrence (RR: 1.73; 95% CI 1.22-2.47; P=0.02) and cancer-specific mortality (RR=2.50, 95% CI=1.71-3.68; P<0.001). We confirmed female gender to be an independent negative prognosis factor for patients following a radical cystectomy and lymphadenectomy for an invasive muscle bladder cancer.

Full Text Available ABSTRACT Introduction: In addition to well-established physical characteristics, Turner syndrome patients have distinct craniofacial morphology. Since short stature is the most typical characteristic, Turner syndrome patients are commonly treated with growth hormone in order to increase final height. At the same time, growth hormone treatment was found to influence craniofacial growth and morphology in various groups of treated patients. Whereas craniofacial characteristics of Turner syndrome patients are well documented, comparatively little is known of craniofacial morphology of those who are treated with growth hormone. Aim: The aim of this study was to investigate craniofacial morphology in Turner syndrome patients treated with growth hormone in comparison to healthy females. Materials and methods: The cephalometric evaluation was conducted on twenty lateral cephalograms of Turner syndrome patients (13.53 ± 4.04 years treated with growth hormone for at least one year (4.94 ± 1.92 years in average. As a control group, forty lateral cephalograms of healthy female controls, who matched Turner syndrome patients by chronological (11.80 ± 2.37 years and skeletal age, were used. Eleven angular, seven linear measurements and six dimensional ratios were measured to describe craniofacial morphology. Results: The results obtained for angular measurements, in cephalometric analyses for Turner syndrome patients treated with growth hormone, revealed bimaxillary retrognathism. The linear measurements indicated longer mandibular ramus, anterior cranial base and both anterior and posterior facial heights. However, posterior cranial base and maxilla were in proportion to the anterior cranial base, when comparing dimensional ratios. Anterior cranial base, maxilla and mandibular ramus were larger in proportion to mandibular body; as well as posterior facial height was when compared to anterior facial height.

Selenomethionine (Se-Met) is the major dietary form of selenium (Se). Detrimental effects have been associated with exposure to elevated dietary selenium. Previous studies have demonstrated effects of Se on the endocrine system, in particular effects on cortisol and thyroid hormones. However, no information is available regarding effects of Se on sex steroid hormones. In the present study, effects of dietary exposure to an environmentally relevant concentration (4.54 mg/kg wet weight (ww)) of Se-Met for 126 days on concentrations of sex steroid hormones in blood plasma of female rainbow trout were determined. Furthermore, the molecular basis for effects of Se-Met on plasma sex steroid hormone concentrations was investigated. Concentrations of androstenedione (A), estrone (E1), and estradiol (E2) were 39.5-, 3.8-, and 12.7-fold greater in plasma of treated females than the untreated controls, respectively. Testosterone (T) was detected only in plasma of treated females. The greater E2 concentration stimulated greater transcript abundance of vitellogenin (vtg) and zona-radiata protein (zrp). Female rainbow trout exposed to Se-Met had greater transcript abundance of key steroidogenic proteins and enzymes, including peripheral benzodiazepine receptor (pbr), cytochrome P450 side-chain cleavage (P450scc), and 3{beta}-hydroxysteroid dehydrogenase (3{beta}-hsd). Exposure to Se-Met did not affect transcript abundance of luteinizing hormone (lh) or follicle stimulating hormone (fsh). Similarly, there was no change in transcript abundance of luteinizing hormone receptor (lhr) or follicle stimulating hormone receptor (fshr). Long-term exposure to dietary Se-Met has the potential to stimulate vitellogenesis in female rainbow trout by directly stimulating ovarian tissue steroidogenesis. This is the first study to report effects of Se on sex steroid hormone production in fish.

The long-term survival of patients treated for Hodgkin's disease (HD) in childhood is high and the chief concern is now being directed toward the late effects of the treatment, including the endocrine dysfunction. Testicular and ovarian functions were assessed in 64 long term survivors (24 females, 40 males) treated for HD in childhood in Slovenia between 1972 and 1994. At diagnosis they were 3–16 years old and had gonadal evaluation 4–27 years later at the age of 13–34. Fifty-four (84%) patients received chemotherapy (ChT), 49 in combination with radiation therapy (RT), 10 received RT alone. Gonadal function was assessed by the clinical examination and measurement of serum concentrations of estradiol and testosterone. Serum levels of LH and FSH were determined in the basal state and after the stimulation. Primary hypogonadism (PH) was found in 30 (47%) patients. Twenty-four of 40 (60%) males had PH with evidence of damage of germinal epithelium, 4 of them had evidence of damage of Leydig cells (LC) and 10 had evidence of dysfunction of LC as well. PH was found in 6 of 24 (25%) females. After therapy for HD PH was more frequent in males than in females. Not only RT but also alkylating agents and procarbazine alone caused damage of LC. Age of patient at the time of treatment was not an important risk factor for gonadal toxicity. Pelvic RT in combination with ChT is the most important risk factor of the development PH both, in males and females

Recent studies have demonstrated that behavioral traits are subject to transgenerational modification by paternal environmental factors. We previously reported on the transgenerational influences of increased paternal stress hormone levels on offspring anxiety and depression-related behaviors. Here, we investigated whether offspring sociability and cognition are also influenced by paternal stress. Adult C57BL/6J male mice were treated with corticosterone (CORT; 25mg/L) for four weeks prior to paired-matings to generate F1 offspring. Paternal CORT treatment was associated with decreased body weights of female offspring and a marked reduction of the male offspring. There were no differences in social behavior of adult F1 offspring in the three-chamber social interaction test. Despite male offspring of CORT-treated fathers displaying hyperactivity in the Y-maze, there was no observable difference in short-term spatial working memory. Spatial learning and memory testing in the Morris water maze revealed that female, but not male, F1 offspring of CORT-treated fathers had impaired memory retention. We used our recently developed methodology to analyze the spatial search strategy of the mice during the learning trials and determined that the impairment could not be attributed to underlying differences in search strategy. These results provide evidence for the impact of paternal corticosterone administration on offspring cognition and complement the cumulative knowledge of transgenerational epigenetic inheritance of acquired traits in rodents and humans.

The B-Lactam antibiotics have been suggested to have some degree of neurotoxicity in experimental animals as well as in clinical situations. This study has been elucidated the alteration in hippocampal and cerebellum function following adolescent imipenem exposure in male and female rats. Hippocampus and cerebellum related behavioral dysfunction in imipenem -treated [intraperitoneally, 40 and 80 mg/kg/day for one week from 23-day-old] rats were analyzed using explorative, motor function, learning and memory tasks [grasping, rotarod, open field shuttle box and Morris water maze tests]. Exposure to imipenem especially in high dosage impaired the motor coordination in male and female rats. There weren't any differences in grasping time in male and female rats. When the rearing and grooming frequency of their recorded in open field test, both males and females were dramatically affected by exposure to imipenem. Compared to the saline, male and female rats trained one week after imipenem injection showed significant memory deficits in the shuttle box and Morris water maze tests. Results in this study suggested that animals treated with imipenem suffer from motor activity and cognitive impairment. However, hippocampal and cerebellum functions of male and female rats were profoundly affected by exposure to imipenem while no sex-differences in the most variable were evident.

Full Text Available Sex steroids have direct effects on the skeleton. Estrogen acts on the skeleton via the classical genomic estrogen receptors alpha and beta (ERα and ERβ, a membrane ER, and the non-genomic G-protein coupled estrogen receptor (GPER. GPER is distributed throughout the nervous system, but little is known about its effects on bone. In male rats, adaptation to loading is neuronally regulated, but this has not been studied in females.We used the rat ulna end-loading model to induce an adaptive modeling response in ovariectomized (OVX female Sprague-Dawley rats. Rats were treated with a placebo, estrogen (17β-estradiol, or G-1, a GPER-specific agonist. Fourteen days after OVX, rats underwent unilateral cyclic loading of the right ulna; half of the rats in each group had brachial plexus anesthesia (BPA of the loaded limb before loading. Ten days after loading, serum estrogen concentrations, dorsal root ganglion (DRG gene expression of ERα, ERβ, GPER, CGRPα, TRPV1, TRPV4 and TRPA1, and load-induced skeletal responses were quantified. We hypothesized that estrogen and G-1 treatment would influence skeletal responses to cyclic loading through a neuronal mechanism. We found that estrogen suppresses periosteal bone formation in female rats. This physiological effect is not GPER-mediated. We also found that absolute mechanosensitivity in female rats was decreased, when compared with male rats. Blocking of adaptive bone formation by BPA in Placebo OVX females was reduced.Estrogen acts to decrease periosteal bone formation in female rats in vivo. This effect is not GPER-mediated. Gender differences in absolute bone mechanosensitivity exist in young Sprague-Dawley rats with reduced mechanosensitivity in females, although underlying bone formation rate associated with growth likely influences this observation. In contrast to female and male rats, central neuronal signals had a diminished effect on adaptive bone formation in estrogen-deficient female rats.

Full Text Available The aim of this paper is to determine the level of improvement of motor skills of female volleyball players influenced by kinesiology operators in a period of 6 months. Research was conducted on sample subject of 130 female volleyball players aged from 13±0.6 (mean±SD. Sample variables are divided in two groups: 9 variables of assessment of basic motor skills and 5 variables of assessment of situational motor skills. Analysing difference of arithmetic means between of initial and final measures of treated variables it is determined that there is statistically significant difference on the level Sig=0.001, except for variables of Jelka test which determinates speed duration of female volleyball players. Analysis of quantity changes of basic motor skills, shows that the most important projections on selected discriminative function of basic motor skills have the following variables: body lifting in 30 sec; dynamometry of a hand, hand tapping; pull-up; throwing a 1 kg ball from lying position; side defence movement; push-up on bars and situational motor skill are the variables: precision of tactic serving; consecutive bumping; wall-spikes. Comprehensive development of female volleyball players and diversity in the level of volleyball specialization of the development will depend on systematic work on treated motor skills. This program appeared to be efficient. However, it is necessary to gradually increase the demands for the female volleyball players and to put the accent on performance of acquired situational motor skills in future work.

Objectives: This study aimed to find the factors that affect dental esthetics and smile attractiveness in orthodontically treated patients according to laypeople’s judgment, and to determine whether there is any relationship between dental and smile esthetics. Materials and Methods: Using the Q-sort technique, 60 laypersons (30 males, 30 females) rated dental and smile photographs of 48 orthodontically treated patients based on their degree of attractiveness. Dental and smile parameters of each rated image were measured by Smile Analyzer software. The Student’s t-test and chi-square test were used to compare dental and smile parameters between attractive and unattractive images. The logistic regression was used to assess which variables predicted dental and smile esthetics in treated individuals. Results: The philtral to commissural height ratio and gingival display were significantly different in attractive and unattractive smiles (P=0.003 and P=0.02, respectively). None of the dental variables were found to be a determinant of dental esthetics at the end of the orthodontic treatment (P>0.05). According to the judgment of all raters (female and male) and the male raters’ judgment, smile attractiveness could be predicted by philtral to commissural height ratio and buccal corridor ratio (Pesthetics and smile attractiveness in orthodontically treated patients (P>0.05). Conclusion: The philtral to commissural height ratio and buccal corridor ratio can be considered as predictors of smile attractiveness in orthodontically treated patients. Achieving dental esthetics at the end of orthodontic treatment does not guarantee smile attractiveness. PMID:26877739

Prenatal testosterone (T) excess during midgestation leads to estrous cycle defects and polycystic ovaries in sheep. We hypothesized that follicular persistence causes polycystic ovaries and that cyclic progesterone (P) treatment would overcome follicular persistence and restore cyclicity. Twice-weekly blood samples for P measurements were taken from control (C; n = 16) and prenatally T-treated (T60; n = 14; 100 mg T, im, twice weekly from d 30-90 of gestation) Suffolk sheep starting before the onset of puberty and continuing through the second breeding season. A subset of C and T60 sheep were treated cyclically with a modified controlled internal drug-releasing device for 13-14 d every 17 d during the first anestrus (CP, 7; TP, 6). Transrectal ovarian ultrasonography was performed for 8 d in the first and 21 d in the second breeding season. Prenatal T excess reduced the number, but increased the duration of progestogenic cycles, reduced the proportion of ewes with normal cycles, increased the proportion of ewes with subluteal cycles, decreased the proportion of ewes with ovulatory cycles, induced the occurrence of persistent follicles, and reduced the number of corpora lutea in those that cycled. Cyclic P treatment in anestrus, which produced one third the P concentration seen during luteal phase of cycle, did not reduce the number of persistent follicles, but increased the number of progestogenic cycles while reducing their duration. These findings suggested that follicular persistence might contribute to the polycystic ovarian morphology. Cyclic P treatment was able to only partially restore follicular dynamics, but this may be related to the low replacement concentrations of P achieved.

Treatment with selective serotonin reuptake inhibitors, such as fluoxetine, produces sexual side effects with low sexual desire being the most prevalent effect in females. In few studies have preclinical models for such antidepressant-induced sexual dysfunction been fruitful. In the current manuscript, the effects of fluoxetine on multiple measures of female sexual motivation and sexual receptivity were examined. Ovariectomized, Fischer rats were primed with 10 μg estradiol benzoate and 500 μg progesterone. Partner preference, active investigation of the male, and measures of sexual behavior were examined after injection with 15 mg/kg fluoxetine. Factors (pretesting for sexual behavior, size of the test arena, non-contact time with a male) that differ among experiments designed to study antidepressant-induced female rat sexual dysfunction were studied. The male preference ratio was not affected by fluoxetine treatment but active investigation of the male was reduced; lordosis behavior was inhibited and pretesting for sexual receptivity amplified fluoxetine's inhibition; size of the testing arena or non-contact experience with the male had no effect. Regardless of test condition, when given the opportunity to escape from the male, fluoxetine-treated females displayed escape behavior. Measures of male preference and active investigation, but not lordosis behavior, appeared to be affected by fluoxetine's impact on activity. The collective data provided a behavioral profile of fluoxetine-induced sexual dysfunction. These findings reinforce the value of multiple measures when attempting to model antidepressant-induced female sexual dysfunction. PMID:22835821

Since the millennium we have witnessed significant strides in the science and treatment of female sexual dysfunction (FSD). This forward progress has included (i) the development of new theoretical models to describe healthy and dysfunctional sexual responses in women; (ii) alternative classification strategies of female sexual disorders; (iii) major advances in brain, hormonal, psychological, and interpersonal research focusing on etiologic factors and treatment approaches; (iv) strong and effective public advocacy for FSD; and (v) greater educational awareness of the impact of FSD on the woman and her partner. To review the literature and describe the best practices for assessing and treating women with hypoactive sexual desire disorder, female sexual arousal disorder, and female orgasmic disorders. The committee undertook a comprehensive review of the literature and discussion among themselves to determine the best assessment and treatment methods. Using a biopsychosocial lens, the committee presents recommendations (with levels of evidence) for assessment and treatment of hypoactive sexual desire disorder, female sexual arousal disorder, and female orgasmic disorders. The numerous significant strides in FSD that have occurred since the previous International Consultation of Sexual Medicine publications are reviewed in this article. Although evidence supports an integrated biopsychosocial approach to assessment and treatment of these disorders, the biological and psychological factors are artificially separated for review purposes. We recognize that best outcomes are achieved when all relevant factors are identified and addressed by the clinician and patient working together in concert (the sum is greater than the whole of its parts).

Full Text Available Abstract Background Several suicide and suicidal behaviour risk factors are highly prevalent in asylum seekers, but there is little insight into the suicide death rate and the suicidal behaviour incidence in this population. The main objective of this study is to assess the burden of suicide and hospital-treated non-fatal suicidal behaviour in asylum seekers in the Netherlands and to identify factors that could guide prevention. Methods We obtained data on cases of suicide and suicidal behaviour from all asylum seeker reception centres in the Netherlands (period 2002-2007, age 15+. The suicide death rates in this population and in subgroups by sex, age and region of origin were compared with the rate in the Dutch population; the rates of hospital-treated suicidal behaviour were compared with that in the population of The Hague using indirect age group standardization. Results The study included 35 suicide deaths and 290 cases of hospital-treated suicidal behaviour. The suicide death rate and the incidence of hospital-treated suicidal behaviour differed between subgroups by sex and region of origin. For male asylum seekers, the suicide death rate was higher than that of the Dutch population (N = 32; RR = 2.0, 95%CI 1.37-2.83. No difference was found between suicide mortality in female asylum seekers and in the female general population of the Netherlands (N = 3; RR = 0.73; 95%CI 0.15-2.07. The incidence of hospital-treated suicidal behaviour was high in comparison with the population of The Hague for males and females from Europe and the Middle East/South West Asia, and low for males and females from Africa. Health professionals knew about mental health problems prior to the suicidal behaviour for 80% of the hospital-treated suicidal behaviour cases in asylum seekers. Conclusions In this study the suicide death rate was higher in male asylum seekers than in males in the reference population. The incidence of hospital-treated suicidal behaviour

Full Text Available Jamu, an Indonesian traditional medicine used for treating ailments or sicknesses  is also well known as a product for slimming especially for women.  Through its packaging design, jamu for women depict female body in the form of photograph and illustrations. The female body is constructed to be seen attractive and become the ideal body. The research aims to read the ideal female body on the packaging design of jamu and to reveal the ideology behind them. We analyzed the packaging design of jamu related to the formation of female body produced by five major manufacturers of traditional medicine that has survived for at least three generations: Air Mancur, Sido Muncul, Jamu Jago, Nyonya Meneer and Jamu Iboe. This analysis uses Roland Barthes' semiotic theory that reveals the linguistic message, the denoted image and rhetoric of the image. Ideal body is still struggling around the stereotype that physically described as thin and also plum with the emphasise on slim waist, big hip and breast. In keeping with the Javanese philosophy, woman's body is identical to the nature. The construction of female body is closely related to social and cultural context. Through the object and the pose, female body is depicted as traditional and modern, natural and cultural.

The Women's international study of long-duration oestrogen after menopause (WISDOM: a randomised controlled trial

2007-02-01

Full Text Available Abstract Background At the time of feasibility work and final design of the trial there was no randomised control trial evidence for the long-term risks and benefits of hormone replacement therapy. Observational studies had suggested that long term use of estrogen was likely to be associated, amongst other things, with reduced risks of osteoporosis and ischaemic heart disease and increased risks of breast and endometrial cancer. Concomitant use of progestogens had been shown to protect against endometrial cancer, but there were few data showing how progestogen might affect estrogen actions on other conditions. Disease specific risks from observational studies suggested that, overall, long-term HRT was likely to be beneficial. Several studies showed that mortality from all causes was lower in HRT users than in non-users. Some secondary cardiovascular prevention trials were ongoing but evidence was also required for a range of outcomes in healthy women. The WISDOM trial was designed to compare combined estrogen and progestogen versus placebo, and estrogen alone versus combined estrogen and progestogen. During the development of WISDOM the Women's Health Initiative trial was designed, funded and started in the US. Design Randomised, placebo, controlled, trial. Methods The trial was set in general practices in the UK (384, Australia (94, and New Zealand (24. In these practices 284175 women aged 50–69 years were registered with 226282 potentially eligible. We sought to randomise 22300 postmenopausal women aged 50 – 69 and treat for ten years. The interventions were: conjugated equine estrogens, 0.625 mg orally daily; conjugated equine estrogens plus medroxyprogesterone acetate 2.5/5.0 mg orally daily; matched placebo. Primary outcome measures were: major cardiovascular disease, osteoporotic fractures, breast cancer and dementia. Secondary outcomes were: other cancers, all cause death, venous thromboembolism and cerebro-vascular disease. Results

Female Pelvic Vein Embolization: Indications, Techniques, and Outcomes

Energy Technology Data Exchange (ETDEWEB)

Lopez, Anthony James, E-mail: consultant@radiologist.co.uk [The Imaging Clinic (United Kingdom)

2015-08-15

Until recently, the main indication for pelvic vein embolization (PVE) in women was to treat pelvic venous congestion syndrome (PVC) but increasingly, patients with refluxing pelvic veins associated with leg varicosities are also being treated. A more unusual reason for PVE is to treat pelvic venous malformations, although such lesions may be treated with sclerotherapy alone. Embolotherapy for treating PVC has been performed for many years with several published studies included in this review, whilst an emerging indication for PVE is to treat lower limb varicosities associated with pelvic vein reflux. Neither group, however, has been subjected to an adequate randomized, controlled trial. Consequently, some of the information presented in this review should be considered anecdotal (level III evidence) at this stage, and a satisfactory ‘proof’ of clinical efficacy remains deficient until higher-level evidence is presented. Furthermore, a wide range of techniques not accepted by all are used, and some standardization will be required based on future mandatory prospective studies. Large studies have also clearly shown an unacceptably high recurrence rate of leg varicose veins following venous surgery. Furthermore, minimally or non-invasive imaging is now revealing that there is a refluxing pelvic venous source in a significant percentage of women with de novo leg varicose veins, and many more with recurrent varicosities. Considering that just over half the world’s population is female and a significant number of women not only have pelvic venous reflux, but also have associated leg varicosities, minimally invasive treatment of pelvic venous incompetence will become a common procedure.

1984-01-01

The percutaneous absorption of 14 C-phenoxy ring labeled triadimefon was studied in adult and young male and female Sprague-Dawley rats. Triadimefon was applied (41.1 to 46.4 micrograms/cm2) in 0.2 ml of acetone to areas comprising 3% of the body surface (7.0 to 14.5 cm2). Thirty-six animals were treated at the initiation of each study. Groups of three animals were subsequently killed at 1, 4, 8, 12, 24, 48, 72, 96, 120, 144, 168, and 192 hr after treatment. Skin from the treated area as well as blood, heart, liver, kidneys, remaining carcass, urine, and feces were analyzed for 14 C by scintillation counting techniques. Based on 14 C counts, triadimefon was lost more rapidly from the skin of young animals (t 1/2, 20 to 25 hr) than from the skin of adult animals (t 1/2, 29 to 53 hr). Recovery studies indicated that adult males, adult females, young males, and young females, respectively, absorbed 53, 82, 57, and 52% of the dose. The rest of the dose based on material balance was presumably lost by evaporation. Approximately 2.5 to 3.9% of the dose penetrated the skin in one hour and was available for absorption. The rate of entry triadimefon into blood was 2 to 2.5 times faster for young than that observed in adult animals. Elimination of it from blood was faster in the case of the young animals. Triadimefon was absorbed through the skins of the adult male, adult female, young male, and young female rats, respectively, at rates of 0.20, 0.50, 0.58, and 0.48 micrograms/hr/cm2 of skin

Sterilization of melon flies: mating competitiveness after treatment with tepa or gamma irradiation and ratios of treated to untreated flies producing population suppression

1976-01-01

Male melon flies, Dacus cucurbitae Coquillett, treated with a single dose of the chemosterilant tepa (tris(l-aziridinyl) phosphine oxide), or with gamma irradiation, either single or fractionated doses, did not differ significantly in sexual competitiveness as determined by percentage hatch of eggs. Mating competitiveness of males treated by either method ranged from 53 to 66 percent of that of untreated males. In another study, melon flies (males and females) sterilized with 0.0125 percent tepa, the threshold dose for both sexes, completely suppressed a population when the ratio was 16:16:1:1 (sterile males-sterile females-untreated males-untreated females) as determined by no egg hatch

Male rats were injected with methadone HCl (METH) at 5 mg/kg s.c. for 4 days prior to mating with drug-free females. Offspring resulting from these matings were compared with offspring of drug-free males. The progeny of METH-treated males gained less weight after weaning and had lighter thymuses as adults (but not in infancy). Gonadal weights did not differ in infancy or adulthood, and adrenal weights were heavier in female offspring in adulthood. In adulthood METH offspring were significantly different from controls on all behavioural tests used (open field activity, activity cage activity, passive avoidance latencies, shuttle box avoidances, and rotarod latencies), with the differences frequently affected by test order, days of testing, or sex of offspring. The effects in progeny of METH-treated males in the absence of differences in litter size or neonatal mortality indicate that paternal drug ingestion prior to mating can produce physiological and behavioural changes in progeny that are not dependent on detectable effects on early viability or growth.

Male and female pattern hair loss are common, chronic dermatologic disorders with limited therapeutic options. In recent years, a number of commercial devices using low-level laser therapy have been promoted, but there have been little peer-reviewed data on their efficacy. To determine whether treatment with a low-level laser device, the US FDA-cleared HairMax Lasercomb®, increases terminal hair density in both men and women with pattern hair loss. Randomized, sham device-controlled, double-blind clinical trials were conducted at multiple institutional and private practices. A total of 146 male and 188 female subjects with pattern hair loss were screened. A total of 128 male and 141 female subjects were randomized to receive either a lasercomb (one of three models) or a sham device in concealed sealed packets, and were treated on the whole scalp three times a week for 26 weeks. Terminal hair density of the target area was evaluated at baseline and at 16- and 26-week follow-ups, and analyzed to determine whether the hypothesis formulated prior to data collection, that lasercomb treatment would increase terminal hair density, was correct. The site investigators and the subjects remained blinded to the type of device they dispensed/received throughout the study. The evaluator of masked digital photographs was blinded to which trial arm the subject belonged. Seventy-eight, 63, 49, and 79 subjects were randomized in four trials of 9-beam lasercomb treatment in female subjects, 12-beam lasercomb treatment in female subjects, 7-beam lasercomb treatment in male subjects, and 9- and 12-beam lasercomb treatment in male subjects, compared with the sham device, respectively. Nineteen female and 25 male subjects were lost to follow-up. Among the remaining 122 female and 103 male subjects in the efficacy analysis, the mean terminal hair count at 26 weeks increased from baseline by 20.2, 20.6, 18.4, 20.9, and 25.7 per cm2 in 9-beam lasercomb-treated female subjects, 12-beam

Urethral diverticula with calculi have a low incidence as reported in the literature. Diverticulum of female urethra is rare, often discovered due to associated complications. We report a case of diverticulum of the female urethra containing giant calculi in a 62-year-old multiparous woman. She consulted with our office due to dysuria and a hard, painful periurethral mass in the anterior vagina wall. The diverticulum was approached surgically by a vaginal route, and local extraction of the calculi and subsequent diverticulectomy successfully treated the condition.Diagnosis of a complicated diverticulum can be easily achieved if one possesses a high degree of clinical symptoms.

To explore stiletto needle and needle-knife for influence of double sufficient weight in treating knee osteoarthritis patients. One hundred and thirteen early and medium term knee osteoarthritis patients were randomly divided into three groups, including stiletto needle group(38 cases), needle-knife group (38 cases) and voltaren group (37 cases). In stiletto needle group, there were 13 males and 25 females with an average of(55.87±7.72) years old, treated by stiletto needle once a week, and 2 weeks were a course; there were 11 males and 27 females in needle-knife group with an average of(57.11±7.07) years old, treated by acupotome once a week, and 2 weeks were a course; there were 12 males and 25 females in voltaren group with an average age of(57.62±8.08) years old, treated by votalin emulsion smearing 3 to 5 cm on painful area of knee joint, three times a day for 2 weeks; 36 patients in normal group, including 11 males and 25 females with a mean age of (55.28±7.55) years old, treated with nothing. Gravitational four lattice used to measure bipedal back and forth load before and after treatment in further observe weight-bearing situation among three groups, d value, which was the distance from center of gravity to original point, was measured as a obvervational index, JOA score was used to evaluate clinical effect. Five patients were fall out, including 2 patients in stiletto needle group, 2 patients in needle-knife group and 1 patient in voltaren group. Other 108 patients were followed-up from 28 to 35 d with an average of 30 d, and without untoward effect. There was significant difference in d value between treatment group and control group at 1 month after treatment( P 0.05), and d value was decreased before treatment than that of after treatment. There was no significant difference in JOA score among treatment group after treatment at 1 month( P 0.05) after treatment at 1 month.

This paper highlights clinical challenges faced when diagnosing and then treating an individual presenting to a child and adolescent psychiatry clinic because of unwelcome comments he made to female peers about their feet. Novel use of exposure therapy helped him effectively decrease his comments from 1 to 2 times per month to once every 6 months. Conceptualizing this case as the individual's failed attempts toward relationships with females instead of sexual harassment led to diminution of problematic behavior. Implications for diagnosis and treatment of individuals with Autistic Disorder displaying problematic behaviors are presented.

Ayahuasca, a psychoactive beverage used by indigenous and religious groups, is generally prepared by the coction of Psychotria viridis and Banisteriopsis caapi plants containing N,N-dimethyltryptamine (DMT) and β-carboline alkaloids, respectively. To investigate the acute toxicity of ayahuasca, the infusion was administered by gavage to female Wistar rats at doses of 30X and 50X the dose taken during a religious ritual, and the animals observed for 14 days. Behavioural functions were investigated one hour after dosing at 15X and 30X using the open field, elevated plus maze, and forced swimming tests. Neuronal activation (c-fos marked neurons) and toxicity (Fluoro-Jade B and Nissl/Cresyl staining) were investigated in the dorsal raphe nuclei (DRN), amygdaloid nucleus, and hippocampal formation brain areas of rats treated with a 30X ayahuasca dose. The actual lethal oral dose in female Wistar rats could not be determined in this study, but was shown to be higher than the 50X (which corresponds to 15.1mg/kg bw DMT). The ayahuasca and fluoxetine treated groups showed a significant decrease in locomotion in the open field and elevated plus-maze tests compared to controls. In the forced swimming test, ayahuasca treated animals swam more than controls, a behaviour that was not significant in the fluoxetine group. Treated animals showed higher neuronal activation in all brain areas involved in serotoninergic neurotransmission. Although this led to some brain injury, no permanent damage was detected. These results suggest that ayahuasca has antidepressant properties in Wistar female at high doses, an effect that should be further investigated. Copyright © 2015 Elsevier B.V. All rights reserved.

The excess in physical activity could be closely linked to considerable negative consequences on the whole body. These dysfunctions called as "female athlete triad"' by the American College of Sports Medicine (ACSM) include amenorrhea, osteoporosis and disorder eating. The female athlete triad poses serious health risks, both on the short and on the long term, to the overall well-being of affected individuals. Sustained low energy availability can impair health, causing many medical complications within skeletal, endocrine, cardiovascular, reproductive and central nervous system. On the contrary, several studies have shown, that physical activity improves cardiovascular risk factors, hormonal profile and reproductive function. These improvements include a decrease in abdominal fat, blood glucose, blood lipids and insulin resistance, as well as improvements in menstrual cyclicity, ovulation and fertility, decreases in testosterone levels and Free Androgen Index (FAI) and increases in sex hormone binding globulin (SHBG). Other studies reported that physical activity improved self-esteem, depression and anxiety. Thus, the aim of this review is to elucidate the effect of physical exercise on female reproductive system and viceversa the impact of hormonal status on physical activity and metabolism. In addition this review supports the idea that physical exercise is a helpful tool for the management of obesity, prevention of cardiovascular, metabolic diseases and female reproductive organs related diseases (e.g. breast cancer). When the excess in physical activity leads up to the female athlete triad, it is imperative to treat each component of the triad by employing both pharmacological and non pharmacological treatments.

It is well known that itai-itai disease with the osteopathy is broken out among multiparas, 40 years of age and up Japanese residents. In this paper we described an experimental study of effect of pregnancy on cadmium treated rats. Female mature rats were administered drinking water containing 50 and 200 ppm cadmium as CdCl/sub 2/. During 180 days of the experiment, three times of pregnancy were succesful, though slight depression of body weight gain was noticed in the 200 ppm group. The cadmium was accumulated in the kidneys, liver and bone proportionally to the amount of cadmium administered. No significant change was recognized in serum calcium, phosphorus and alkaline phosphatase levels after 180 days. Though cadmium 200 ppm treated rats showed slight histological lesions in the proximal convoluted tubules of the kidney, there appeared to be no osteomalacia including excess formation of osteoid tissue.

Purpose: To assess the survival rate of female lung cancer treated at the Institute of Oncology of the Vilnius University, Lithuania during the period between 1996-2005. Materials and Methods: During the period between 1996-2005, 471 women diagnosed with lung cancer were treated at the Department of Thoracic Surgery and Oncology of the Institute of Oncology, Vilnius University. Data on morphology, stage and treatment was collected from the medical records. All lung cancer cases by histology were classified in two groups: non-small cell lung cancer (includes squamous cell carcinoma, large cell carcinoma, adenocarcinoma and other less common types) and small cell lung cancer. The vital status of the study group was assessed as of December 31, 2007, by passive follow-up, using data from the population registry. It was found that 411 (87.3%) of the patients had died. Survival was estimated according to the Kaplan-Meier method. Results: The median survival of female lung cancer diagnosed during 1996-2005 in Lithuania show to be 8.7 months (8.4 (95% CI 7.2-10.8) months with non-small cell lung cancer and 9.3 (95% CI 6.3-13.0) months with small-cell lung cancer). Survival was more than 20 months in resectable non-small cell lung cancer (stages I, II, IIIA). Non-small cell lung cancer survival in advanced stages was less than 7 months. Small-cell lung cancer patients median survival at limited and extended stages of the disease were 9.5 (95% CI 2.9-18.4) compared to 9.2 (95% CI 6.2-13.7) months. Non-small cell lung cancer patients most frequently were treated by surgery (27.0%), surgery and chemotherapy or radiotherapy (19.6%). Small cell lung cancer patient treatment included chemo and radiotherapy (27.0%), chemotherapy (19.0%), radiotherapy (17.5%), surgery (27.9%). Conclusions: The single center study of female lung cancer diagnosed during 1996-2005 in Lithuania show a significantly better chance of survival in resectable non-small cell lung cancer.

The uterus is the major female sex organ and is essential for pregnancy. The organ is located in the pelvic cavity. It is usually fist-sized with its volume changing from 75 to 200 cc depending on the menstrual cycle. There are various diseases associated with the uterus, including malignancy, uterine myoma, postpartum hemorrhage, and vascular malformation. The conventional surgical treatment for these diseases is hysterectomy. However, hysterectomy has some risk, and there may be complications associated with the surgery and anesthesia. In addition, hysterectomy results in loss of fertility and loss of female characteristics, both of which may lead to emotional problems. After uterine artery embolization (UAE) was performed for post-partum bleeding in 1979 and for uterine myoma in 1995, interventional treatment of UAE replaced the existing surgical treatment of hysterectomy. UAE is performed widely as a minimally invasive treatment modality that can preserve the uterus, make pregnancy and childbirth possible and resolve emotional problems. The interventional treatment has become increasingly popular to treat various female genital diseases.

In papain-induced models of emphysema, despite the existing extensive description of the cellular and molecular aspects therein involved, sexual hormones may play a complex and still not fully understood role. Hence, we aimed at exploring the putative gender-related differences in lung mechanics, histology and oxidative stress in papain-exposed mice. Thirty adult BALB/c mice received intratracheally either saline (50 μL) or papain (10 U/50 μL saline) once a week for 2 weeks. In males papain increased lung resistive and viscoelastic/inhomogeneous pressures, static elastance, and viscoelastic component of elastance, while females showed higher static elastance and resistive pressure only. Both genders presented similar higher parenchymal cellularity and mean alveolar diameter, and less collagen-elastic fiber content and body weight gain than their respective controls. Increased functional residual capacity was more prominent in males. Female papain-treated mice were more susceptible to oxidative stress. Thus, male and female papain-exposed mice respond differently, which should be carefully considered to avoid confounding results. Copyright © 2014 Elsevier B.V. All rights reserved.

Full Text Available Was evaluated the influence of alternative methods of detoxification of castor cake on nitrogen balance and ruminal evaluation in sheep fed isocaloric and isonitrogenous experimental diets. Twenty sheep (ten males and ten females were used in five treatments (castor cake untreated, treated with limestone, treated with urea, treated with phosphate monodicalcium and autoclaved and four repetitions. For nitrogen balance we used a randomized block design, with the blocks according to the sex and the variables pH and ammonia nitrogen (NH3-N in the experimental design was split plot, with plots in the diets subplots and the collection times (0, 2, 5 and 8 hours postprandial.The treatments did not influence N intake, N urinary, urea and N-urea concentration in plasma. The Urinary N was higher in diet containing castor cake treated with phosphate monodicalcium (FOS when compared with those containing castor cake treated by autoclave (ACL. Already the nitrogen balance (BN was higher in diet ACL when compared to FOS diet. The pH and N-NH3 were within the normal range of sheep, being little affected by diet. Diets with methods of detoxification of castor cake promoted moderate changes in nitrogen balance with emphasis on the castor cake autoclaved and treated with limestone. The males sheep showed higher nitrogen balance than females.

A cross-sectional study of female condom awareness, usage and concerns among the female undergraduates of the University of Ibadan was conducted in September 2004. The results of 850 out of the 879 female students interviewed were used for analysis (96.6%). Over 80% had knowledge of the female condom as a form of modern contraception and the majority of them learnt about it through the mass media (39.9%) and health workers (34.4%). However, only 11.3% had ever used the female condom, with most (40%) using it to prevent both unwanted pregnancy and sexually transmitted infections including HIV (STI/HIV). The sexual partners' approval was appreciable, accounting for about 42.7% among those that had experience of the female condom usage. Major concerns mentioned such as difficulty of inserting it into the vagina and lack of sexual satisfaction, were not different from those in earlier studies. The result of this study looks promising judging from a high awareness level of the female condom, even though its usage is low. The female condom may be an alternative strategy to combat unsafe sexual practises and its sequelae in a country like Nigeria that is male dominated.

The study was conducted to determine whether a phosphodiesterase (PDE) 3 inhibitor has potential as a novel contraceptive in primates. Regularly cycling adult female cynomolgus macaques of proven fertility (n=16) were treated for 7 months with placebo (controls) or the PDE3 inhibitor ORG 9935 as a daily food treat (150 mg/kg) or as a weekly depot injection (150 mg/kg, sc). After 1 month, a male of proven fertility was introduced into each group. Females underwent weekly monitoring of progesterone (P) and ultrasound evaluation for pregnancy if P remained elevated (1.0 ng/mL) >3 weeks. ORG 9935 values were evaluated using high-performance liquid chromatography. Overall, the pregnancy rate in ORG 9935-treated monkeys (4/8, 50%) did not differ from controls (7/8, 88%; p=.5). However, no animal became pregnant in a cycle when the serum level of ORG 9935 exceeded 300 nmol/L. Moreover, two treated monkeys who mated throughout the treatment phase and did not conceive became pregnant within four cycles after stopping ORG 9935. The other two animals were discontinued prematurely from the protocol. These results demonstrate that ORG 9935 may prevent pregnancy in primates at serum concentrations above 300 nmol/L and that the effect is reversible.

Clinical evidence suggests superior antidepressant response over time with a repeated, intermittent ketamine treatment regimen as compared to a single infusion. However, the club drug ketamine is commonly abused. Therefore, the abuse potential of repeated ketamine injections at low doses needs to be investigated. In this study, we investigated the abuse potential of repeated exposure to either 0, 2.5, or 5 mg/kg ketamine administered once weekly for seven weeks. Locomotor activity and conditioned place preference (CPP) were assayed to evaluate behavioral sensitization to the locomotor activating effects of ketamine and its rewarding properties, respectively. Our results show that while neither males nor females developed CPP, males treated with 5 mg/kg and females treated with either 2.5 or 5 mg/kg ketamine behaviorally sensitized. Furthermore, dendritic spine density was increased in the NAc of both males and females administered 5 mg/kg ketamine, an effect specific to the NAc shell (NAcSh) in males but to both the NAc core (NAcC) and NAcSh in females. Additionally, males administered 5 mg/kg ketamine displayed increased protein expression of ΔfosB, calcium calmodulin kinase II alpha (CaMKIIα), and brain-derived neurotrophic factor (BDNF), an effect not observed in females administered either dose of ketamine. However, males and females administered 5 mg/kg ketamine displayed increased protein expression of AMPA receptors (GluA1). Taken together, low-dose ketamine, when administered intermittently, induces behavioral sensitization at a lower dose in females than males, accompanied by an increase in spine density in the NAc and protein expression changes in pathways commonly implicated in addiction.

Tumorigenic Effects of Tamoxifen on the Female Genital Tract

Directory of Open Access Journals (Sweden)

Kaei Nasu M.D., Ph.D.

2008-01-01

Full Text Available Tamoxifen is widely used for endocrine treatment and breast cancer prevention. It acts as both an estrogen antagonist in breast tissue and an estrogen agonist in the female lower genital tract. Tamoxifen causes severe gynecologic side effects, such as endometrial cancer. This review focuses on the effects of prolonged tamoxifen treatment on the human female genital tract and considers its tumorigenicity in the gynecologic organs through clinical data analysis. Tamoxifen is associated with an increased incidence of benign endometrial lesions such as polyps and hyperplasia and a two- to four-fold increased risk of endometrial cancer in postmenopausal patients. Moreover, the incidence of functional ovarian cysts is significantly high in premenopausal tamoxifen users. To prevent tamoxifen from having severe side effects in gynecologic organs, frequent gynecological examination should be performed for both premenopausal and postmenopausal patients with breast cancer who are treated with this drug.

The aim of the present study was to investigate the cephalometric changes in patients with increased vertical dimension after treatment with cervical headgear compared to controls. The sample of the present retrospective study consisted of 20 Class II patients (10 males, 10 females; mean age 8.54 ± 1.15 years) with increased vertical dimension treated with cervical headgear (treatment group) and 21 Class II patients (11 males, 10 females; mean age 8.41 ± 1.15 years) with increased vertical dimension who underwent no treatment (control group). Cephalograms were available for each subject at baseline (T1) and after treatment/observation time (T2) for both groups and cephalometric analysis allowed for evaluation of changes between time points and between groups. Regarding facial axis, N-ANS/ANS-Me, and overbite, there were no negatively significant changes in the treated group showing no significant worsening in the vertical dimension. Regarding facial angle, there was a significant increase in the treated group between the time points and when compared to the control group, showing counterclockwise rotation of the mandible in the treated group. The vertical dimension was not significantly altered after cervical headgear treatment although the anterior facial height was higher at the beginning of treatment. There was significant counterclockwise rotation of the mandible, and clockwise rotation and distal displacement of the maxilla after treatment.

Stem cell therapeutic possibilities: future therapeutic options for male-factor and female-factor infertility?

Science.gov (United States)

Easley, Charles A; Simerly, Calvin R; Schatten, Gerald

2013-07-01

Recent advances in assisted reproduction treatment have enabled some couples with severe infertility issues to conceive, but the methods are not successful in all cases. Notwithstanding the significant financial burden of assisted reproduction treatment, the emotional scars from an inability to conceive a child enacts a greater toll on affected couples. While methods have circumvented some root causes for male and female infertility, often the underlying causes cannot be treated, thus true cures for restoring a patient's fertility are limited. Furthermore, the procedures are only available if the affected patients are able to produce gametes. Patients rendered sterile by medical interventions, exposure to toxicants or genetic causes are unable to utilize assisted reproduction to conceive a child - and often resort to donors, where permitted. Stem cells represent a future potential avenue for allowing these sterile patients to produce offspring. Advances in stem cell biology indicate that stem cell replacement therapies or in-vitro differentiation may be on the horizon to treat and could cure male and female infertility, although significant challenges need to be met before this technology can reach clinical practice. This article discusses these advances and describes the impact that these advances may have on treating infertility. Copyright © 2013 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

Investigate the possible effects of Tribulus terrestris (TT) on endocrine sensitive organs in intact and castrated male rats as well as in a post-menopausal rat model using ovariectomized females. Three different dose levels of TT (11, 42 and 110 mg/kg/day) were administered to castrated males for 7 days and to intact males and castrated females for 28 days. In addition to TT treatment, all experiments also included a group of rats treated with dehydroepiandrosterone (DHEA). In experiments using castrated males and females we also used testosterone and 17 alpha-ethynylestradiol, respectively, as positive controls for androgenicity and estrogenicity. Neither DHEA nor TT was able to stimulate androgen sensitive tissues like the prostate and seminal vesicle in both intact and castrated male rats. In addition, administration of TT to intact male rats for 28 days did not change serum testosterone levels as well as did not produce any quantitative change in the fecal excretion of androgenic metabolites. However, a slight increase in the number of homogenization-resistant spermatids was observed in rats treated with 11 mg/kg/day of TT extract. In ovariectomized females, TT did not produce any stimulatory effects in uterine and vaginal epithelia. Tribulus terrestris was not able to stimulate endocrine sensitive tissues such as the prostate, seminal vesicle, uterus and vagina in Wistar rats, indicating lack of androgenic and estrogenic activity in vivo. We also showed a positive effect of TT administration on rat sperm production, associated with unchanged levels of circulating androgens. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

Consequences of advanced aging on renal function in chronic hyperandrogenemic female rat model: implications for aging women with polycystic ovary syndrome.

Patil, Chetan N; Racusen, Lorraine C; Reckelhoff, Jane F

2017-11-01

Polycystic ovary syndrome (PCOS) is the most common endocrine and reproductive disorder in premenopausal women, characterized by hyperandrogenemia, metabolic syndrome, and inflammation. Women who had PCOS during their reproductive years remain hyperandrogenemic after menopause. The consequence of chronic hyperandrogenemia with advanced aging has not been studied to our knowledge. We have characterized a model of hyperandrogenemia in female rats and have aged them to 22-25 months to mimic advanced aging in hyperandrogenemic women, and tested the hypothesis that chronic exposure to hyperandrogenemia with aging has a deleterious effect on renal function. Female rats were chronically implanted with dihydrotestosterone pellets (DHT 7.5 mg/90 days) that were changed every 85 days or placebo pellets, and renal function was measured by clearance methods. Aging DHT-treated females had a threefold higher level of DHT with significantly higher body weight, mean arterial pressure, left kidney weight, proteinuria, and kidney injury molecule-1 (KIM-1), than did age-matched controls. In addition, DHT-treated-old females had a 60% reduction in glomerular filtration rate, 40% reduction in renal plasma flow, and significant reduction in urinary nitrate and nitrite excretion (UNOxV), an index of nitric oxide production. Morphological examination of kidneys showed that old DHT-treated females had significant focal segmental glomerulosclerosis, global sclerosis, and interstitial fibrosis compared to controls. Thus chronic hyperandrogenemia that persists into old age in females is associated with renal injury. These data suggest that women with chronic hyperandrogenemia such as in PCOS may be at increased risk for development of chronic kidney disease with advanced age. © 2017 The Authors.

Mycoplasma genitalium: Should We Treat and How?

Science.gov (United States)

Broad, Jennifer M.; Golden, Matthew R.

2011-01-01

Mycoplasma genitalium is associated with acute and chronic urethritis in men. Existing data on infection in women are limited and inconsistent but suggest that M. genitalium is associated with urethritis, cervicitis, pelvic inflammatory disease, and possibly female infertility. Data are inconclusive regarding the role of M. genitalium in adverse pregnancy outcomes and ectopic pregnancy. Available data suggest that azithromycin is superior to doxycycline in treating M. genitalium infection. However, azithromycin-resistant infections have been reported in 3 continents, and the proportion of azithromycin-resistant M. genitalium infection is unknown. Moxifloxacin is the only drug that currently seems to uniformly eradicate M. genitalium. Detection of M. genitalium is hampered by the absence of a commercially available diagnostic test. Persons with persistent pelvic inflammatory disease or clinically significant persistent urethritis or cervicitis should be tested for M. genitalium, if possible. Infected persons who have not previously received azithromycin should receive that drug. Persons in whom azithromycin therapy fails should be treated with moxifloxicin. PMID:22080266

Reproducibility and genital sparing with a vaginal dilator used for female anal cancer patients

Briere, Tina Marie; Crane, Christopher H.; Beddar, Sam; Bhosale, Priya; Mok, Henry; Delclos, Marc E.; Krishnan, Sunil; Das, Prajnan

2012-01-01

Purpose: Acute vulvitis, acute urethritis, and permanent sexual dysfunction are common among patients treated with chemoradiation for squamous cell carcinoma of the anal canal. Avoidance of the genitalia may reduce sexual dysfunction. A vaginal dilator may help delineate and displace the vulva and lower vagina away from the primary tumor. The goal of this study was to evaluate the positional reproducibility and vaginal sparing with the use of a vaginal dilator. Materials and methods: Ten female patients treated with IMRT for anal cancer were included in this study. A silicone vaginal dilator measuring 29 mm in diameter and 114 mm in length was inserted into the vagina before simulation and each treatment. The reproducibility of dilator placement was investigated with antero-posterior and lateral images acquired daily. Weekly cone beam CT (CBCT) imaging was used to confirm coverage of the GTV, which was typically posterior and inferior to the dilator apex. Finally, a planning study was performed to compare the vaginal doses for these 10 patients to a comparable group of 10 female patients who were treated for anal cancer with IMRT without vaginal dilators. Results: The absolute values of the location of the dilator apex were 7.0 ± 7.8 mm in the supero-inferior direction, 7.5 ± 5.5 mm in the antero-posterior, and 3.8 ± 3.1 mm in the lateral direction. Coverage of the GTV and CTV was confirmed from CBCT images. The mean dose to the vagina was lower by 5.5 Gy, on average, for the vaginal dilator patients, compared to patients treated without vaginal dilators. Conclusion: The vaginal dilator tended to be inserted more inferiorly during treatment than during simulation. For these ten patients, this did not compromise tumor coverage. Combined with IMRT treatment planning, use of a vaginal dilator could allow for maximum sparing of female genitalia for patients undergoing radiation therapy for anal cancer.

Full Text Available Background: Botulinum toxin (BT use for enhancing the facial features has become a commonly accepted form of aesthetic intervention. This study conducted a self-report survey of female BT users in order to explore the motivating factors in its use (cost-benefit analysis. Settings and Design: This is a cross-sectional exploratory pilot study. Materials and Methods: Self-report questionnaires were administered to 41 consecutive clients attending an independent medical practice for BT injections for cosmetic purposes. All the participants were females and represented a range of age groups from the 20s to above 60s. Items in the nonstandardized questionnaire elicited questions relating to the reasons for and against BT use. Statistical Analysis Used: Descriptive analysis was used rather than inferential statistics, and involved ranking the responses according to the most likely reasons for using BT and disadvantages of its use. Results: In general, the primary motivating factor for BT use was to improve self-esteem, and the greatest disadvantage involved financial costs associated with the procedure. Conclusions: The main findings of this study suggest that females who use BT for aesthetic purposes are motivated by personal psychological gains (intrapersonal attributes rather than social gains (interpersonal factors.

While literature on the interplay between educational leadership and context abounds, the attention granted to the experiences of female principals has, to a large extent, treated the construction of women as a homogeneous entity. Consequently, very little, certainly within the South African context, is known about how women in leadership…

To assess the perceived fertility status and to determine the association between perceived fertility status and sexual function, as reported by young female Hodgkin lymphoma survivors. Young female Hodgkin lymphoma survivors are at risk of infertility and impaired sexual function. However, little is known about their awareness of infertility and its association with sexual functioning. A descriptive questionnaire survey. In this cross-sectional study, a survey was completed by female Hodgkin lymphoma survivors (40 years). Outcome measures included self-reported fertility status and sexual problems and the internationally validated Female Sexual Function Index. In total, 36 survivors were included (mean age 32 years, SD 4). Eighteen women (50%) thought themselves fertile. Eight survivors (22%) who perceived themselves as being infertile were more often treated with alkylator-based chemotherapy, and 63% reported sexual dysfunction. Ten survivors (28%) were not aware as to whether they were fertile or not; seven of these would like to have children. The reported fertility status was related to age and chemotherapy regimen. Regarding sexuality, 14 (39%) of the female Hodgkin lymphoma survivors reported one or more sexual problem and none reported recovery. Female sexual dysfunction according to the Female Sexual Function Index was reported by 11 (31%) survivors. Almost 30% of Hodgkin lymphoma survivors do not know whether they are fertile or not. Overall sexual dysfunction is common in Hodgkin lymphoma survivors and comparable to the general population. However, a lack of desire was significantly more often reported in female Hodgkin lymphoma survivors. To prevent assumed infertility and unintended childlessness by postponing parenthood in young female survivors, awareness of fertility status is needed. There is also a need to routinely assess sexual function and provide adequate interventions to improve arousal and lubrication problems. © 2013 John Wiley & Sons Ltd.

2014-09-01

The purpose of this study was to examine the effects of including female athletes' weights in athletic event programs on female spectators' body image, eating disorder symptoms, self-esteem, and affective state and to investigate whether the magnitude of the athletes' reported weights had differential effects on female spectators (i.e., do female spectators who view heavier athletes respond differently than those who view less heavy athletes?). We used an experimental design to examine hypotheses derived from competing theories to determine whether exposure to female athletes of varying weight would adversely or beneficially impact female undergraduates (N = 152) who served as athletic event spectators. Analyses indicated that in this simulated study, female spectators' body image, eating disorder symptoms, self-esteem, and affective states were not impacted by the presence or by the magnitude of female athletes' weights in athletic event programs. The results imply that including athletes' weights in game-day programs at women's athletic events does not affect female spectators on an individual level.

Vitellogenin (Vg), a yolk protein precursor, is the primary egg nutrient source involved in insect reproduction and embryo development. The Cotton Boll weevil (CBW) Anthonomus grandis Boheman, the most important cotton pest in Americas, accumulates large amounts of Vg during reproduction. However, the precise role of this protein during embryo development in this insect remains unknown. Herein, we investigated the effects of vitellogenin (AgraVg) knockdown on the egg-laying and egg viability in A. grandis females, and also characterized morphologically the unviable eggs. AgraVg transcripts were found during all developmental stages of A. grandis, with highest abundance in females. Silencing of AgraVg culminated in a significant reduction in transcript amount, around 90%. Despite this transcriptional reduction, egg-laying was not affected in dsRNA-treated females but almost 100% of the eggs lost their viability. Eggs from dsRNA-treated females showed aberrant embryos phenotype suggesting interference at different stages of embryonic development. Unlike for other insects, the AgraVg knockdown did not affect the egg-laying ability of A. grandis, but hampered A. grandis reproduction by perturbing embryo development. We concluded that the Vg protein is essential for A. grandis reproduction and a good candidate to bio-engineer the resistance against this devastating cotton pest.

Endometriosis is a chronic estrogen and progestogen responsive inflammatory disease associated with pain symptoms and infertility. The medical therapy of endometriosis aims to induce decidualization within the hormonally dependent ectopic endometrium, and it is often administered to ameliorate women' pain symptoms or to prevent post-surgical disease recurrence. A variety of progestins have been used in monotherapy for the medical management of women with endometriosis. Areas covered: This review aims to offer the reader a complete overview of pharmacokinetic (PK) and clinical efficacy of progestins for the treatment of endometriosis. Expert opinion: Each progestin has a distinct PK parameters and pharmacodynamics affinity not only for progesterone receptor, but also for other steroid receptors, such as estrogen, androgen, and glucocorticoid. Moreover, progestins can also be delivered in different formulations. All these characteristics influence their final biological effect. Randomized, controlled, non-blinded studies support the use of oral progestin-only treatment for pelvic pain associated with endometriosis. Currently, the only two progestins approved by Food and Drug Administration (FDA) for the treatment of endometriosis are norethindrone acetate (NETA) and depot medroxyprogesterone acetate (DMPA).

2003-01-01

An experiment was conducted on female damascus goats the breeding season to diagnose pregnancy on days 21-22 and 40-44 after mating and to monitor the corpora lutea function during different reproductive stages by measuring serum progesterone levels using radioimmunoassay. A total of 75 intact female damascus goats were divided into 3 equal groups, S, P and C. females in group S were fitted with sponges containing 60 mg of medroxyprogesterone acetate (MAP) for 14 days and injected, at the sponge withdrawal, with pregnant mare serum gonadotrophin (PMSG). Females in group P were injected twice with prostaglandin F 2a at 11 day intervals. Females in group C (control) received no treatment. The results indicated that the accuracy of positive pregnancy on days 21-22 and 40-44 was 90.5% and 94.4%, respectively, and it was 100% for detecting non-pregnancy. There was no significant difference(p>0.05)among the 3 groups in serum progesterone level between days 21-22 and 40-44 after mating. Whereas, there were significant(p -1 at matinf, during pregnancy and at kidding. The triplet carrying goats had a significantly(p -1 , respectively. While, there was no significant difference in serum progesterone levels between the single and twin-carrying goats

The vertebrate estrogens include 17-β-estradiol (E2), which has an analog in silkworm ovaries. In this study, the Bombyx mori vitellogenin gene (BmVg) was used as a biomarker to analyze the function of the E2 in silkworm. In most oviparous animals, Vg has female-specific expression. However, BmVg expression was also detected in B. mori males. Stage specific fluctuation of BmVg expression was similar in males and females, but expression levels in males were lower than in females. E2 treatment by injection or feeding of male larvae in the final instar stage induced and stimulated male BmVg transcription and protein synthesis. When silkworm ovary primordia were transplanted into males, BmVg was induced in male fat bodies. Transplanted ovaries primordia were also able to develop into ovaries and produce mature eggs. When females were treated with E2 promoted BmVg/BmVn protein accumulation in hemolymph, ovaries and eggs. However, BmVg transcription was decreased in female fat bodies. An E2 analog was identified in the hemolymph of day 3 wandering silkworms using high-performance liquid chromatography. Estradiol titers from fifth late-instar larvae to pupal stage were determined by enzyme-linked immunosorbent assay. The results suggested that silkworms synthesized a vertebrate E2 analog. This study found that E2 promoted the synthesis of BmVg, a female typical protein in silkworms. Copyright © 2014 Elsevier Inc. All rights reserved.

Protective Effect of Ethanolic Extract of Grape Pomace against the Adverse Effects of Cypermethrin on Weanling Female Rats

2015-01-01

Full Text Available The adverse effect of cypermethrin on the liver and kidney of weanling female rats and the protective effect of ethanolic extract of grape pomace were investigated in the present study. Weanling female rats were given cypermethrin oral at a dose of 25 mg kg−1 body weight for 28 consecutive days. An additional two Cyp-trated groups received extract at a dose of 100 and 200 mg kg−1 body weight, respectively, throughout the experimental duration. Three groups more served as extract and control groups. Administration of Cyp resulted in a significant increase in serum marker enzymes, for example, aminotransferases (AST and ALT, alkaline phosphatase (ALP, and gamma-glutamyl transferase (GGT, and increases the level of urea nitrogen and creatinine. In contrast, Cyp caused significant decrease in levels of total protein and albumin and caused histopathological alterations in liver and kidneys of female rats. Coadministration of the extract to Cyp-treated female rats restored most of these biochemical parameters to within normal levels especially at high dose of extract. However, extract administration to Cyp-treated rats resulted in overall improvement in liver and kidney damage. This study demonstrated the adverse biohistological effects of Cyp on the liver and kidney of weanling female rats. The grape pomace extract administration prevented the toxic effect of Cyp on the above serum parameters. The present study concludes that grape pomace extract has significant antioxidant and hepatorenal protective activity.

Benefits and risks of ovarian function and reproduction for cancer development and prevention.

Science.gov (United States)

Schindler, Adolf E

2011-12-01

Ovarian function and menstrual cycle disturbances, pregnancy, and reproductive medicine procedures can either increase gynecological cancer risk or prevent cancer development. For ovarian cancer development, there are two hypotheses, which are connected with ovulation and gonadotropin secretion. Most of the ovarian cancers seem to be derived from displaced ovarian surfice epithelial cells. One year of ovulatory cycles increases the ovarian cancer risk by 6%. Ovulation between 22 and 29 years of age causes the highest risk increase per year. In contrast, progesterone or progestins appear to create protection. Lifestyle can affect or modify ovarian cancer risk. Breast cancer risk is very much related to age of menarche and menopause, pregnancy, and breast feeding. All of which are related to ovarian function and progestogenic impact that translates either into breast cancer risk increase or decrease. This is modified by body mass index, physical activity, and lifestyle in general. The risk of endometrial cancer is most closely related to endogenous progesterone during the menstrual cycle and pregnancy or by exogenous progestogens as in oral contraceptives. These effects are progestogen dose and time dependent. Endometrial cancer risk can also be increased by estrogen-producing tumors or long-term estrogen treatment.

Polycystic ovary syndrome (PCOS) is an endocrine disorder among women of reproductive age characterized by chronic anovulation and polycystic ovary morphology and/or hyperandrogenism. Management of clinical manifestations of PCOS, such as menstrual irregularities and hyperandrogenism symptoms, includes lifestyle changes and combined hormonal contraceptives (CHCs). CHCs contain estrogen that exerts antiandrogenic properties by triggering the hepatic synthesis of sex hormone-binding globulin that reduces the free testosterone levels. Moreover, the progestogen present in CHCs and in progestogen-only contraceptives suppresses luteinizing hormone secretion. In addition, some types of progestogens directly antagonize the effects of androgens on their receptor and also reduce the activity of the 5α reductase enzyme. However, PCOS is related to clinical and metabolic comorbidities that may limit the prescription of CHCs. Clinicians should be aware of risk factors, such as age, smoking, obesity, diabetes, systemic arterial hypertension, dyslipidemia, and a personal or family history, of a venous thromboembolic event or thrombophilia. This article reports a narrative review of the available evidence of the safety of hormonal contraceptives in women with PCOS. Considerations are made for the possible impact of hormonal contraceptives on endocrine, metabolic, and cardiovascular health.

Full Text Available The substitution of equine chorionic gonadotropin (eCG by follicle-stimulating hormone (FSH in protocols for synchronization of ovulation in Santa Inês ewes was assessed. Ten females were submitted to the insertion of intravaginal sponges containing 60 mg medroxyprogesterone acetate for 10 days; after this period sponges were withdrawn and the animals were randomly divided into two groups. Group 1 (n = 5: intramuscular injection of 0.5 mL d-cloprostenol and 300 UI eCG; Group 2 (n = 5: intramuscular injection of 0.5 mL d-cloprostenol and 20 mg FSH. Interval between sponge withdrawal and estrus beginning was 27.7 h and 35.9 h for eCG and FSH, respectively. Interval between sponge withdrawal and the end of estrus was 55.8 h for eCG treatment and 55.6 h for FSH treatment. Estrus length was 29.3 h and 19.6 h, for eCG and FSH treatments, respectively. The biggest follicle and the second in size measured 0.74 cm and 0.54 cm for eCG treatment, whereas for the FSH treatment they measured 0.73 and 0.50 cm. The interval between the beginning of estrus and ovulation was similar within all groups: 21.0 h for eCG treated ewes and 25.2 h for the ones treated with FSH. Ewes treated with eCG presented an interval of 47.5 h between sponge withdrawal and ovulation, while the ones treated with FSH presented a 61.1 h interval. Ovulation occurred 8.3 h before the end of estrus in the eCG group. On the other hand, ewes treated with FSH ovulated 5.5 h after the end of estrus. Estrus and ovulation were efficiently synchronized in Santa Inês ewes by using long-term progestogen protocol associated to the administration of 20 mg FSH, along with Prostaglandin F2α (PGF2α at the moment of sponge withdrawal, thus substituting the use of eCG.

Full Text Available This is a qualitative—quantitative study based on hospital records of female patients of reproductive age, presenting sexual dysfunction, and treated with 250 mg Tribulus terrestris extract (1 tablet thrice daily for 90 days. Safety monitoring included vital signs, physical examination, laboratory tests, and occurrence of adverse events. Efficacy analysis included results of the Female Sexual Function Index (FSFI, dehydroepiandrosterone (DHEA levels together with total and free testosterone, and the patient and physician assessments. There was a statistically significant improvement in total FSFI scores ( P < 0.0001 post-treatment, with improvement among 106 (88.33% subjects. There was a statistically significant ( P < 0.0001 increase in the level of DHEA, while the levels of both serum testosterone ( P = 0.284 and free testosterone decreased ( P < 0.0001. Most adverse events recorded were related to the gastrointestinal tract. Physical examination showed no significant changes post-treatment. Based on the results, it is concluded that the T. terrestris extract is safe and effective in the treatment of female sexual dysfunction.

Life history trade-offs are often hierarchical with decisions at one level affecting lower level trade-offs. We investigated trade-off structure in female side-blotched lizards (Uta stansburiana), which exhibit two evolved strategies: yellow-throated females are K-strategists and orange-throated are r-strategists. Corticosterone treatment was predicted to differentially organize these females' reproductive decisions. Corticosterone-treated yellow females suppressed reproduction but survived well, and augmented egg mass without decreasing clutch size. Conversely, corticosterone enhanced mortality and reproductive rates in orange females, and increased egg mass only after lengthy exposure. Corticosterone did not affect post-laying condition, suggesting that corticosterone increased egg mass through enhanced energy acquisition (income breeding). Corticosterone enhanced survival of lightweight females, but decreased survival of heavy females, introducing a foraging vs. predation trade-off. We conclude that rather than being a direct, functional relationship, observed trade-offs between offspring size and number represent evolved differences in hierarchical organization of multidimensional trade-offs, particularly in response to stress.

Chanas, Brian; Wang, Hongbing; Ghanayem, Burhan I.

Acrylonitrile (AN) is a potent toxicant and a known rodent carcinogen. AN epoxidation to cyanoethylene oxide (CEO) via CYP2E1 and its subsequent metabolism via epoxide hydrolases (EH) to yield cyanide is thought to be responsible for the acute toxicity and mortality of AN. Recent reports showed that male mice are more sensitive than females to the acute toxicity/mortality of AN. The present work was undertaken to assess the metabolic and enzymatic basis for the greater sensitivity of male vs female mice to AN toxicity. Male and female wild-type and CYP2E1-null mice received AN at 0, 2.5, 10, 20, or 40 mg/kg by gavage. Cyanide concentrations were measured at 1 or 3 h after dosing. Current data demonstrated that cyanide levels in blood and tissues of AN-treated wild-type mice of both sexes were significantly greater than in vehicle-treated controls and increased in a dose-dependent manner. In contrast, cyanide levels in AN-treated CYP2E1-null mice were not statistically different from those measured in vehicle-treated controls. Furthermore, higher levels of cyanide were detected in male wild-type mice vs females in association with greater sensitivity of males to the acute toxicity/mortality of this chemical. Using Western blot analysis, negligible difference in CYP2E1 expression with higher levels of soluble and microsomal EH (sEH and mEH) was detected in the liver of male vs female mice. In kidneys, male mice exhibited higher expression of both renal CYP2E1 and sEH than did female mice. In conclusion, higher blood and tissue cyanide levels are responsible for the greater sensitivity of male vs female mice to AN. Further, higher expression of CYP2E1 and EH in male mice may contribute to greater formation of CEO and its subsequent metabolism to yield cyanide, respectively

There have been no reports of primary leiomyosarcoma of the stomach treated by endoscopic submucosal dissection (ESD). We report an extremely rare case of gastric leiomyosarcoma that was successfully treated by ESD. An asymptomatic 74-year-old female underwent esophagogastroduodenoscopy for screening in December 2013. A centrally depressed submucosal tumor 10 mm in diameter was detected at the posterior wall of the upper gastric body. Follow-up esophagogastroduodenoscopy conducted 5 months later showed that the tumor diameter had increased to 15 mm. Endoscopic ultrasound revealed a hypoechoic mass located in the second to the middle of the third layer. Endoscopic ultrasound-guided fine-needle aspiration demonstrated a myogenic tumor. The tumor was completely resected by ESD without complications. Immunohistopathological diagnosis of the resected specimen was gastric leiomyosarcoma derived from the muscularis mucosae, with negative lateral and vertical margins. No local recurrence or metastasis has been detected at 36 months after ESD. This is the first report of gastric leiomyosarcoma treated by ESD in the English language literature.

The degree to which one identifies as male or female has a profound impact on one's life. Yet, there is a limited understanding of what contributes to this important characteristic termed gender identity . In order to reveal factors influencing gender identity, studies have focused on people who report strong feelings of being the opposite sex, such as male-to-female (MTF) transsexuals. To investigate potential neuroanatomical variations associated with transsexualism, we compared the regional thickness of the cerebral cortex between 24 MTF transsexuals who had not yet been treated with cross-sex hormones and 24 age-matched control males. Results revealed thicker cortices in MTF transsexuals, both within regions of the left hemisphere (i.e., frontal and orbito-frontal cortex, central sulcus, perisylvian regions, paracentral gyrus) and right hemisphere (i.e., pre-/post-central gyrus, parietal cortex, temporal cortex, precuneus, fusiform, lingual, and orbito-frontal gyrus). These findings provide further evidence that brain anatomy is associated with gender identity, where measures in MTF transsexuals appear to be shifted away from gender-congruent men.

Hot or not: the effects of exogenous testosterone on female attractiveness to male conspecifics in the budgerigar.

Directory of Open Access Journals (Sweden)

Stefanie E P Lahaye

Full Text Available An increasing number of studies indicate that not only females but also males can be selective when choosing a mate. In species exhibiting male or mutual mate choice, females may benefit from being attractive. While male attractiveness is often positively influenced by higher plasma levels of the androgenic hormone testosterone, it has been shown that testosterone can masculinise female behavior and morphology in several bird species, potentially rendering them less attractive. In this study, we investigated whether female budgerigars, Melopsittacusundulatus, suffer from increased plasma testosterone levels through a negative effect on their attractiveness to males. We experimentally increased plasma testosterone levels in testosterone-treated females (T-females compared to controls (C-females and allowed males to choose between a T- and a C-female in a two-way choice situation. Although testosterone treatment significantly affected female behavioral and morphological characteristics, males did not show a significant difference in preference between T- and C-females. These results suggest that experimentally increasing testosterone levels in females does not appear to influence male preference during initial mate choice. Our findings indicate that selection for higher levels of testosterone in male budgerigars is probably not constrained by a correlated response to selection causing negative effects on female attractiveness during initial mate choice. Evaluating whether or not a potential constraint may arise from negative testosterone-induced effects on other fitness related traits in females requires further work.

Full Text Available Evaluation of protective effect of fennel on mouse ovary against the destructive effects of cyclophosphamide (CP was the aim of this study. Adult female NMARI mice were randomly divided into six groups (n = 8: (A negative control, (B CP200 mg/kg, (C fennel 400 mg/kg/day, (E, F, and D that received fennel 200, 400 and 100 mg/kg/day respectively + CP200 mg/kg. Their ovary weight, volume, and diameter (WVD were measured. Five micron sections were stained using the H&E method. The serum levels of oestrogen and progesterone were measured using ELISA kit. The results showed that WVD significantly reduced in the CP-treated groups in comparison with the A and C, but WVD increased after treatment of the mice with fennel extract, in comparison with B group. A significant decrease of serum in terms of oestrogen and progesterone levels among CP-treated groups in comparison with the A group was observed. In the CP-treated groups a reduction in the number of different ovarian follicles in comparison with the A and C groups was observed. However, in the treated animals with fennel extract, these parameters significantly increased in comparison with the B group. Finally, it is concluded that fennel can protect ovary from cyclophosphamide side effects. Keywords: Cyclophosphamide, Fennel, Mice, Ovary

Health concerns for HIV-infected persons on antiretroviral therapy (ART) have moved from morbidity to the challenges of long-term ART. We investigated the effect of Zidovudine or Nevirapine on reproductive capacity across two mouse generations. A prospective mouse study with drugs administered through one spermatogenic cycle. Mouse groups (16 males and 10 females) were given Zidovudine or Nevirapine for 56 days. Males were mated to untreated virgin females to determine dominant lethal effects. Twenty females (10 treated and 10 untreated) mated with the treated males per dose and gave birth to the F1 generation. Parental mice were withdrawn from drugs for one spermatogenic cycle and mated to the same dams to ascertain if effects are reversible. The F1 generation were exposed for another 56 days and mated to produce the F2 generation. Foetal loss was indicated in the dominant lethal assay as early as four weeks into drug administration to the males. At the first mating of the parental generation to produce the F1 generation, births from 10 dams/dose when the 'father-only' was exposed to Zidovudine (10, 100 and 250 mg/kg) was 3, 2 and 1 while it was 7, 1 and 4 respectively when 'both-parents' were exposed. Similarly births from the parental generation first mating when the 'father-only' was exposed to Nevirapine (5, 50 and 150 mg/kg) was 2, 2 and 0 while it was 6, 5 and 9 respectively when 'both-parents' were exposed. However, fertility was not significantly different neither by dose nor by the parental exposure. The F1 mice mated to produce the F2 generation recorded only one birth. The dominant lethal analysis showed foetal loss occurred when the "fathers-only" were treated while fertility was enhanced when "both-parents" were on therapy at the time of mating.

At the first mating of the parental generation to produce the F1 generation, births from 10 dams/dose when the 'father-only' was exposed to Zidovudine (10, 100 and 250 mg/kg was 3, 2 and 1 while it was 7, 1 and 4 respectively when 'both-parents' were exposed. Similarly births from the parental generation first mating when the 'father-only' was exposed to Nevirapine (5, 50 and 150 mg/kg was 2, 2 and 0 while it was 6, 5 and 9 respectively when 'both-parents' were exposed. However, fertility was not significantly different neither by dose nor by the parental exposure. The F1 mice mated to produce the F2 generation recorded only one birth.The dominant lethal analysis showed foetal loss occurred when the "fathers-only" were treated while fertility was enhanced when "both-parents" were on therapy at the time of mating.

Full Text Available Nathan W Kopper, Jennifer Gudeman, Daniel J ThompsonKV Pharmaceutical, St. Louis, MO, USAAbstract: Vasomotor symptoms (VMS associated with menopause can cause significant discomfort and decrease the quality of life for women in the peri-menopausal and post-menopausal stages of life. Hormone therapy (HT is the mainstay of treatment for menopausal symptoms and is currently the only therapy proven effective for VMS. Numerous HT options are available to treat VMS, including estrogen-only and estrogen-progestogen combination products to meet the needs of both hysterectomized and nonhysterectomized women. In addition to selecting an appropriate estrogen or estrogen-progestogen combination, consideration should be given to the route of administration to best suit the needs of the patient. Delivery systems for hormone therapy include oral tablets, transdermal patches, transdermal topical (nonpatch products, and intravaginal preparations. Oral is currently the most commonly utilized route of administration in the United States. However, evidence suggests that oral delivery may lead to some undesirable physiologic effects caused by significant gut and hepatic metabolism. Transdermal drug delivery may mitigate some of these effects by avoiding gut and hepatic first-pass metabolism. Advantages of transdermal delivery include the ability to administer unmetabolized estradiol directly to the blood stream, administration of lower doses compared to oral products, and minimal stimulation of hepatic protein production. Several estradiol transdermal delivery technologies are available, including various types of patches, topical gels, and a transdermal spray.Keywords: estradiol, hormone therapy, menopause, transdermal drug delivery, vasomotor symptoms

Spontaneous splenic artery aneurysm rupture in a 38-year old female: a case report.

Science.gov (United States)

Koutserimpas, C; Papachristou, E; Nikitakis, N; Zannes, N; Tellos, A; Velimezis, G

Splenic artery aneurysm (SAA) is a rare and extremely difficult diagnosis. A rare case of a ruptured SAA in a 38-year old female, firstly treated with endovascular embolization and then with splenectomy, is presented. A 38-year old female presented to the emergency department with epigastric pain and fainting episodes. Direct catheter angiography revealed a ruptured SAA and distal, as well as proximal coil embolization was performed. Due to abdominal compartment syndrome the patient underwent open surgery with splenic artery ligation and splenectomy. Postoperative she showed signs of sepsis and was treated with i.v. fluids, steroids, packed red blood cells, platelets, fresh frozen plasma and antimicrobial treatment. Additionally, a multidrug resistant Acinetobacter baumanni was yielded from the urine culture. She had a satisfactory recovery. She is followed up a total of 5 years with no signs of overwhelming post-splenectomy infection syndrome. Direct catheter angiography is a very helpful option in diagnosis, as well as treatment, but a close monitoring after embolization is essential. Furthermore, post-splenectomy sepsis is a severe disease with high mortality rates that requires immediate appropriate treatment.

Polyamines play an essential role in tissue growth and differentiation, in body weight increment, in brain organization, and in the molecular mechanisms of hormonal action, intracellular signaling, and cell-to-cell communication. In a previous study, inhibition of their synthesis by alpha-difluoromethylornithine (DFMO), a specific and irreversible inhibitor of ornithine decarboxylase, during development in female rats, was followed by prolonged high follicle-stimulating hormone (FSH) serum level and a delayed puberty onset. Those changes were relatively independent of body mass and did not impair posterior fertility. The present work studies the mechanisms and site of action of polyamine participation in FSH secretion during development. DFMO was injected in female rats between Days 1 and 9 on alternate days. At 10 days of age, hypothalami from control and DFMO rats were perifused in vitro, and basal and potassium-induced gonadotropin-releasing hormone (GnRH) release were measured. The response to membrane depolarization was altered in DFMO hypothalami. Increased GnRH release in response to a low K+ concentration was evidenced. Adenohypophyses of the same treated prepubertal rats were perifused in vitro and the response to GnRH pulses was checked. In DFMO-treated rats, higher FSH release was observed, with no changes in LH or PRL secretion. Finally, pituitary GnRH receptor number in adenohypophyseal membranes from treated and control groups was quantified. A significant reduction in specific binding was evident in hypophyses from DFMO-treated rats when compared with binding in the control group. In summary, DFMO treatment in a critical developmental period in the female rat impacts the immature GnRH neuronal network and immature gonadotropes. A delay in maturation is evidenced by a higher sensitivity to secretagogs in both pituitary glands and hypothalamic explants. These events could explain the prolonged high FSH serum levels and delayed puberty onset seen in

FEMALE SEXUAL AUTONOMY: THE FEMALE CONDOM IN EROTIC PRACTICES

Full Text Available The objective was to learn about the experiences of women from a Health Strategy in view of the experience of sexual autonomy in the face of the female condom. It is an exploratory and qualitative study, completed in April 2010, which used semi-structured interview as data collection technique and the theory of social constructionism to aid in data analysis. Of the total of 25 women participants, after six months, only 12 were still in continuous use of the female condom. They pointed out the female condom as able to provide them with bargaining power, since it is inserted into their bodies. For some, the difficulty of trading remained for failure partner's approval. It is observed that in practice, the female condom becomes hostage of gender relations.

Female qualities in males are common in vertebrates but have not been extensively reported in insects. Vitellogenin (Vg) is highly expressed in the female fat body and is generally required for the formation of yolk proteins in the insect egg. Vg upregulation is generally regarded as a female quality in female oviparous animals. In this study, we found that Bombyx mori Vg (BmVg) is especially highly expressed in the female pupa. Downregulation of the BmVg gene in the female pupa by RNA interference (RNAi) interfered with egg formation and embryonic development, showing the importance of BmVg in these processes. So, we used BmVg as a biomarker for female qualities in the silkworm. Hematoxylin-eosin staining and immunofluorescence histochemistry showed that ovary transplants induced BmVg synthesis in the male pupa fat body. Ovaries transplanted into male silkworms produced only a few eggs with deformed yolk granules. These results suggested that the amount of BmVg in the male silkworm was insufficient for eggs to undergo complete embryonic development. After 17-beta-estradiol was used to treat male pupae and male pupal fat bodies, BmVg was upregulated in vivo and in vitro. These findings indicated that the male silkworm has innate female qualities that were induced by a transplanted ovary and 17β-estradiol. However, in silkworms, female qualities in males are not as complete as in females. Copyright © 2014 Elsevier Inc. All rights reserved.

Effects of testosterone on sexual behavior and morphology in adult female leopard geckos, Eublepharis macularius.

Science.gov (United States)

Rhen, T; Ross, J; Crews, D

1999-10-01

The leopard gecko, Eublepharis macularius, is a species in which testosterone (T) is the primary circulating sex hormone in adults of both sexes. There are, however, sex differences in T physiology. Whereas males have prolonged periods with high T levels, T levels cycle in accord with follicular development in females. Specifically, T concentration increases during vitellogenesis, drops after ovulation, and then remains at previtellogenic levels until eggs are laid and the next follicular cycle begins. To determine the function of T in females, we manipulated both the level and the duration of T elevation using Silastic implants in intact, adult female leopard geckos. Females had low ( approximately 1 ng/ml), medium ( approximately 100 ng/ml), or high ( approximately 200 ng/ml) T levels for either a short (8 days) or a long (35 days) duration. Behavior tests with males were conducted on days 1-5 in the short-duration group or on days 29-33 in the long-duration group. For both short- and long-duration groups, T treatment decreased attractivity in females with medium and high T levels compared to females with low T levels. In contrast, females with a medium T level were more receptive than females with a low T level in the short-duration group. Females in the long-duration group were unreceptive regardless of T level. Females treated for a long duration also displayed more aggression toward and evoked more aggression from males than short duration females. Short-duration T treatment had no masculinizing effect on female morphology, whereas medium and high T levels for a long duration induced development of hemipenes. Overall, these results suggest that T can both increase and decrease sexual behaviors in the female leopard gecko.

Tributyltin contributes in reducing the vascular reactivity to phenylephrine in isolated aortic rings from female rats.

Organotin compounds such as tributyltin (TBT) are used as antifouling paints by shipping companies. TBT inhibits the aromatase responsible for the transformation of testosterone into estrogen. Our hypothesis is that TBT modulates the vascular reactivity of female rats. Female Wistar rats were treated daily (Control; CONT) or TBT (100 ng/kg) for 15 days. Rings from thoracic aortas were incubated with phenylephrine (PHE, 10(-10)-10(-4) M) in the presence and absence of endothelium, and in the presence of N(G)-Nitro-L-Arginine Methyl Ester (L-NAME), tetraethylammonium (TEA) and apocynin. TBT decreased plasma levels of estrogen and the vascular response to PHE. In the TBT group, the vascular reactivity was increased in the absence of endothelium, L-NAME and TEA. The decrease in PHE reactivity during incubation with apocynin was more evident in the TBT group. The sensitivity to acetylcholine (ACh) and sodium nitroprusside (SNP) was reduced in the TBT group. TBT increased collagen, reduced α1-smooth muscle actin. Female rats treated with TBT for 15 days showed morphology alteration of the aorta and decreased their vascular reactivity, probably due to mechanisms dependent on nitric oxide (NO) bioavailability, K(+) channels and an increase in oxidative stress.

EI-Sherbiny, E.M.; EI-Mahdy, A.A.

2008-01-01

Hepatic toxicity through carbon tetrachloride (CCI 4 ) induced lipid peroxidation was extensively used in experimental models to understand the cellular mechanisms behind oxidative damage and to evaluate the therapeutic potential of drugs and dietary antioxidants. The ameliorative effect of Aloe vera juice and carrot supplementation on hepato carcinogenesis induced by carbon tetrachloride in adult female albino rats was investigated. The carcinogenic process was determined by measuring gamma-glutamyl transpeptidase (GGT), ornithine carbamyl transferase (OCT), thiobarbituric acid reactive substances (TBARs), representing levels of lipid peroxides, and carcinoembryonic antigen (CEA) in the sera of female albino rats. Carbon tetrachloride significantly elevated the serum GGT, OCT activities and the level of TBARs. Administration of Aloe vera leaf juice filtrate after CCl 4 treatment resulted in a non-significant modification in GGT, OCT activities and significantly improved the level of TBARs in comparison with control. Supplementation of carrot to CCI 4 treated animals led to a great amelioration in OCT activity and TBARs level, whereas GGT activity was ameliorated but statistically changed compared to control. There was a non-significant alteration in the level of CEA in all treated groups compared to normal control one

Deviation from the normative sex-pattern of infant deaths is so large in Egypt that nearly 1/3 of female deaths can be attributed to a sex-specific cause: lesser care of the female child. This article reports on child neglect which may account for the relatively lower survival rate of the female infant, despite its biological advantage over the male. This knowledge is seen as vital in planning interventions. The investigation answers 3 questions relating to the sex-specific factors of death among female infants: do girls display a poorer level of nutrition compared to boys? Is there evidence to show that sickness episodes of female infants are treated more carelessly than those of male infants? Are there reasons to believe that girls are more exposed to life-threatening psychological factors than are boys? A group of 598 families in low-income districts of Cairo was randomly chosen to receive regular monthly visits by a team of trained field invstigators over a 1-year period. The sample is thought to represent life in urban quarters of Egypt, described as pervasively rural in orientations despite urban occupations and living conditions. The study finds no significant sex difference in nutritional status until the 6th month of life. Around this period, 2/5 of the female group but 1/4 of the male show signs of malnutrition as measured by weight. The difference continues to increase and is very statistically significant by the end of the year. Nutritional status of female infants tended to decline with an addition of daughters in the family. Also, at birth orders 2 ot 5 and in large families of 4-5 children, the relative nutritional disadvantage of the female infant is statistically significant. Moreover, a very distinct sex-difference in dietary patterns is observed as no boy was deprived of supplementary feeding during the 2nd 1/2 of the year but only 1/15 girls received food other than breast milk during this period. Despite some evidence highly suggestive of

Numerous studies have shown contradictory variable percentages of recurrent HPV lesions, after various therapies. The present study therefore evaluates the effectiveness of CO2 laser vaporization in the treatment of single-site HPV lesions of the lower female genital tract in order to confirm the conviction that physical therapy alone, in agreement with some findings reported in the literature, is capable of guaranteeing a high cure rate in selected patients. From January 1995 to June 1996, seventy- five female patients were treated with CO2 laser vaporization for single-site genital HPV lesions, some of which were associated with low-grade intra-epithelial neoplasia. The success rate after 12 months proved to be 97%. The pre-existing clinical symptoms disappeared in all the patients treated. No complication in the vaporization procedure was encountered.

We present a case of a 16-year-old Caucasian female with a history of major depressive disorder and post-traumatic stress disorder who was admitted to an inpatient adolescent psychiatric unit with symptoms of conversion disorder, including non-epileptic seizures, an inability to speak or walk, and not eating on her own. She has a history of multiple previous medical and psychiatric hospitalizations without any significant resolution of symptoms, and extensive medical workups have all been negative. Treatment ultimately involved reassuring the patient and family that there was no underlying medical condition and emphasizing the conversion disorder diagnosis. The patient participated daily in physical therapy to improve mobility, deconditioning, and functioning. Hospital staff was instructed on the nature of the non-epileptic seizures, which continued to occur during the hospitalization. After one month, the patient was discharged home fully functional: walking, speaking, and eating on her own. One week after discharge, the patient presented with the same symptoms and was readmitted to the psychiatric facility. She subsequently never regained her previous level of functioning, and she was ultimately transferred to a residential treatment facility. We will discuss factors that led to the initial improvement and the factors that led to recurrence and persistence of symptoms. © The Author(s) 2015.

Female feticide in India.

Science.gov (United States)

Ahmad, Nehaluddin

2010-01-01

Women are murdered all over the world. But in India a most brutal form of killing females takes place regularly, even before they have the opportunity to be born. Female feticide--the selective abortion of female fetuses--is killing upwards of one million females in India annually with far-ranging and tragic consequences. In some areas, the sex ratio of females to males has dropped to less than 8000:1000. Females not only face inequality in this culture, they are even denied the right to be born. Why do so many families selectively abort baby daughters? In a word: economics. Aborting female fetuses is both practical and socially acceptable in India. Female feticide is driven by many factors, but primarily by the prospect of having to pay a dowry to the future bridegroom of a daughter. While sons offer security to their families in old age and can perform the rites for the souls of deceased parents and ancestors, daughters are perceived as a social and economic burden. Prenatal sex detection technologies have been misused, allowing the selective abortions of female offspring to proliferate. Legally, however, female feticide is a penal offence. Although female infanticide has long been committed in India, feticide is a relatively new practice, emerging concurrently with the advent of technological advancements in prenatal sex determination on a large scale in the 1990s. While abortion is legal in India, it is a crime to abort a pregnancy solely because the fetus is female. Strict laws and penalties are in place for violators. These laws, however, have not stemmed the tide of this abhorrent practice. This article will discuss the socio-legal conundrum female feticide presents, as well as the consequences of having too few women in Indian society.

Somatic symptoms among US adolescent females: associations with sexual and physical violence exposure.

2013-12-01

The objective of this study is to examine the association between physical and sexual violence exposure and somatic symptoms among female adolescents. We studied a nationally representative sample of 8,531 females, aged 11-21 years, who participated in the 1994-1995 Wave I of the National Longitudinal Study of Adolescent Health (Add Health). Female adolescents were asked how often they had experienced 16 specific somatic symptoms during the past 12 months. Two summary categorical measures were constructed based on tertiles of the distributions for the entire female sample: (a) total number of different types of symptoms experienced, and (b) number of frequent (once a week or more often) different symptoms experienced. Groups were mutually exclusive. We examined associations between adolescents' violence exposure and somatic symptoms using multinomial logistic regression analyses. About 5 % of adolescent females reported both sexual and non-sexual violence, 3 % reported sexual violence only, 36 % reported non-sexual violence only, and 57 % reported no violence. Adolescents who experienced both sexual and non-sexual violence were the most likely to report many different symptoms and to experience very frequent or chronic symptoms. Likelihood of high symptomatology was next highest among adolescents who experienced sexual violence only, followed by females who experienced non-sexual violence only. Findings support an exposure-response association between violence exposure and somatic symptoms, suggesting that symptoms can be markers of victimization. Treating symptoms alone, without addressing the potential violence experienced, may not adequately improve adolescents' somatic complaints and well-being.

Genetically significant dose and sex ratio of the offsprings of patient treated with 131I for hyperthyroidism

Takeshita, Akihisa

1975-01-01

The gonadal doses following the 131 I treatment of 6 male and 14 female patients with hyperthyroidism were calculated by the method of MIRD, measuring daily radioactivity in the thyroid gland and circulating blood. The testicular dose was 0.52 +- 0.256 rads and the ovarian dose was 0.632 +- 0.488 rads per mCi. In 1965, the genetically significant dose from 131 I treatment of 925 patients with hyperthyroidism was estimated to be 0.0136 mrads/person/year. The genetically significant dose would amount to 0.0613 mrads/person/year, assuming that the total amount of 131 I supplied for treatment in 1965 was administered to treat the hyperthyroid patients with an age-and sex distribution similar to that of the above mentioned group of patients. Sex ratios of the offspring of male and female patients treated with 131 I from 1953 to 1966 were compared with those of offspring born to male and female patients before the treatment. The proportion of males was higher among the offspring of male patients after 131 I treatment than among the offspring of the controls, but the difference was not statistically significant. The sex ratio of the offspring of female patients was not different from that of controls. The mean age of the parents at the times of their children's birth after 131 I treatment was 2.6 - 6.0 year older in male patients and 2.8 - 2.9 year older in female patients than that of controls.

The future of research in female pelvic medicine.

Science.gov (United States)

Chao, Jamie; Chai, Toby C

2015-02-01

Female pelvic medicine and reconstructive surgery (FPMRS) was recently recognized as a subspecialty by the American Board of Medical Specialties (ABMS). FPMRS treats female pelvic disorders (FPD) including pelvic organ prolapse (POP), urinary incontinence (UI), fecal incontinence (FI), lower urinary tract symptoms (LUTS), lower urinary tract infections (UTI), pelvic pain, and female sexual dysfunction (FSD). These conditions affect large numbers of individuals, resulting in significant patient, societal, medical, and financial burdens. Given that treatments utilize both medical and surgical approaches, areas of research in FPD necessarily cover a gamut of topics, ranging from mechanistically driven basic science research to randomized controlled trials. While basic science research is slow to impact clinical care, transformational changes in a field occur through basic investigations. On the other hand, clinical research yields incremental changes to clinical care. Basic research intends to change understanding whereas clinical research intends to change practice. However, the best approach is to incorporate both basic and clinical research into a translational program which makes new discoveries and effects positive changes to clinical practice. This review examines current research in FPD, with focus on translational potential, and ponders the future of FPD research. With a goal of improving the care and outcomes in patients with FPD, a strategic collaboration of stakeholders (patients, advocacy groups, physicians, researchers, professional medical associations, legislators, governmental biomedical research agencies, pharmaceutical companies, and medical device companies) is an absolute requirement in order to generate funding needed for FPD translational research.

Female Veterans of Iraq and Afghanistan seeking care from VA specialized PTSD Programs: comparison with male veterans and female war zone veterans of previous eras.

Differences in the characteristics and mental health needs of female veterans of the Iraq/Afghanistan war compared with those of veterans of other wars may have useful implications for VA program and treatment planning. Female veterans reporting service in the Iraq/Afghanistan war were compared with women reporting service in the Persian Gulf and Vietnam wars and to men reporting service in the Iraq/Afghanistan war. Subjects were drawn from VA administrative data on veterans who sought outpatient treatment from specialized posttraumatic stress disorder (PTSD) treatment programs. A series of analyses of covariance (ANCOVA) was used to control for program site and age. In general, Iraq/Afghanistan and Persian Gulf women had less severe psychopathology and more social supports than did Vietnam women. In turn, Iraq/Afghanistan women had less severe psychopathology than Persian Gulf women and were exposed to less sexual and noncombat nonsexual trauma than their Persian Gulf counterparts. Notable differences were also found between female and male veterans of the Iraq/Afghanistan war. Women had fewer interpersonal and economic supports, had greater exposure to different types of trauma, and had different levels of diverse types of pathology than their male counterparts. There appear to be sufficient differences within women reporting service in different war eras and between women and men receiving treatment in VA specialized treatment programs for PTSD that consideration should be given to program planning and design efforts that address these differences in every program treating female veterans reporting war zone service.

Azadirachtin impact on mate choice, female sexual receptivity and male activity in Drosophila melanogaster (Diptera: Drosophilidae).

Azadirachtin, a neem compound (Azadirachta indica) with medical and anti-insect properties, is one the most successful botanical pesticides in agricultural use. However, its controversial impact on non-targeted species and its mechanism of action need to be clarified. In addition, Azadirachtin impact on pre- and post-mating traits remains largely undocumented. The current study examined the effects of Azadirachtin on Drosophila melanogaster as a non-target and model species. Azadirachtin was applied topically at its LD 50 (0.63μg) on the day of adult emergence and its effect was evaluated on several traits of reproductive behavior: mate choice, male activity, female sexual receptivity, sperm storage and female sterility. In choice and no choice conditions, only male treatment reduced mating probability. Female treatment impaired mating probability only when males had the choice. Males' mating ability may have been impaired by an effect of the treatment on their mobility. Such an effect was observed in the actimeter, which revealed that treated males were less active than untreated ones, and this effect persisted over 8days. Azadirachtin treatment had, however, no effect on the nycthemeral rhythm of those males. Even when mating occurred, Azadirachtin treatment impaired post-mating responses especially when females or both sexes were treated: remating probability increases and female fertility (presence of larvae) decreases. No impairment was observed on the efficiency of mating, evaluated by the presence of sperm in the spermatheca or the ventral receptacle. Male treatment only had no significant effect on these post-mating responses. These findings provide clear evidence that Azadirachtin alters the reproductive behavior of both sexes in D. melanogaster via mating and post-mating processes. Copyright © 2017 Elsevier Inc.

To describe pattern of female genital tract cancers seen at Olabisi Onabanjo University Teaching Hospital (OOUTH), Sagamu, Nigeria. This is a retrospective review of all cases of female genital tract cancers managed at the Gynaecology department of OOUTH, Sagamu, Nigeria. OOUTH is a tertiary health institution of the State's university and it takes referrals from within and outside the State. Case records of all female genital tract cancers managed between January 2004 and December 2013 were retrieved and analysed using SPSS version 16.0. There were 2059 women treated forvarious gynaecologic conditions, 179 (8.7%) were cases of female genital tract cancers and 161 records were available for analysis. Cervical cancer constituted the commonest (51.6%), followed by ovarian (35.4%), endometrial (9.9%), and choriocarcinoma (1.9%). There were no cases of vaginal and fallopian tube cancers. The lowest mean age was found in choriocarcinoma (36.60 ± 4.50 years) and highest in vulvar cancer (70.00 ± 2.82 years). The mean ages for cervical, endometrial and ovarian cancers were (51.98 ± 12.39), (65.38 ± 7.24), and (54.42 ± 10.51) years respectively. Similarly the least mean parity was found in choriocarcinoma (2.33 ± 1.52), and the highest in vulvar cancer (6.00 ± 1.44). The mean parity for cervical, endometrial, and ovarian were (4.10 ± 1.49),(3.06 ± 1.48), and (3.72 ± 1.68) respectively. These differences are statistically significant, age; F = 7.61, p < 0.0001, and parity; F = 3.27, p= 0.013. Incidence of cervical, endometrial, and ovarian cancers remain high and presentations are at late stages. There is a need to improve on cervical cancer screening, and for the attending physicians to improve on their indices of suspicions as regards endometrial and ovarian cancers.

To investigate the therapeutic effect of pulsatile GnRH (gonadorelin) pump on female patients with idiopathic hypogonadotropic hypogonadism (IHH). In this retrospective study, five female IHH patients were recruited. Patients were treated with pulsatile gonadorelin (10 µg per 90 min) via a pump for at least 12 weeks. Serum gonadotropins and sex steroid levels were measured, and menses were recorded. After one-week treatment, luteinizing hormone (LH) level increased from (2.2 ± 2.0) U/L to (5.4 ± 2.5) U/L (P=0.028), follicle-stimulating hormone(FSH) level increased from (3.7 ± 2.7) U/L to(6.3 ± 1.0) U/L (P=0.162), and estradiol (E2) level increased from (58 ± 13) pmol/L to (260 ± 97) pmol/L (P=0.011). Menstrual bleeding was observed in 4 patients after starting treatment for 35-55 days and two natural pregnancies were reported. No menstrual bleeding was reported in another patient. The frequency of pulsatile GnRH had to be adjusted according to endogenous GnRH secretion during the follicular phase of normal women and regular menses were induced. Pulsatile GnRH is effective in treating female IHH. A constant frequency of pulsatile GnRH is suitable for most of IHH patients. However, for those who failed to produce regular menses, adjusting pulsatile frequency to imitate the physiological rhythm of GnRH may be an alternative option.

Exhaustive exercises can cause delayed menarche or menstrual cycle irregularities in females. Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) are incorporated into a wide range of benefits in many physiological systems. Our work aimed to assess the role of ω-3 PUFA docosahexaenoic acid (DHA) on the deleterious effects of exhaustive exercise on the female reproductive system in rats. Virgin female rats were randomly divided into 4 groups (12 rats in each): control group, omega-3 group treated with DHA, exhaustive exercise group, and exhaustive exercised rats treated with DHA. Omega-3 was given orally to the rats once daily for 4 estrous cycles. Exhaustive exercises revealed lower levels in progesterone and gonadotropins together with histopathological decrease in number of growing follicles and corpora lutea. Moreover, the exercised rats showed low levels of ovarian antioxidants with high level of caspase-3 and plasma cortisol level that lead to disruption of hypothalamic-pituitary-gonadal axis. ω-3 PUFA DHA has beneficial effects on the number of newly growing follicles in both sedentary and exercised rats with decreasing the level of caspase-3 and increasing the antioxidant activity in ovaries. Exhaustive exercises can cause ovulatory problems in female rats that can be improved by ω-3 supplementation.

. Included studies had high attrition rates, and investigators often did not blind adequately or did not clearly describe randomisation procedures. Medical treatment versus placebo Progestogen (medroxyprogesterone acetate (MPA)) was more effective than placebo at the end of treatment in terms of the number of women achieving a greater than 50% reduction in visual analogue scale (VAS) pain score immediately after treatment (Peto OR 3.00, 95% CI 1.70 to 5.31, two studies, n = 204, I(2) = 22%, moderate-quality evidence). Evidence of benefit was maintained up to nine months after treatment (Peto OR 2.09, 95% CI 1.18 to 3.71, two studies, n = 204, I(2) = 0%, moderate-quality evidence). Women treated with progestogen reported more adverse effects (e.g. weight gain, bloatedness) than those given placebo (high-quality evidence). The estimated effect of lofexidine on pain outcomes when compared with placebo was compatible with benefit and harm (Peto OR 0.42, 95% CI 0.11 to 1.61, one study, 39 women, low-quality evidence). Women in the lofexidine group reported more adverse effects (including drowsiness and dry mouth) than women given placebo (moderate-quality evidence). Head-to-head comparisons of medical treatments Head-to-head comparisons showed that women taking goserelin had greater improvement in pelvic pain score (MD 3, 95% CI 2.08 to 3.92, one study, n = 47, moderate-quality evidence) at one year than those taking progestogen. Women taking gabapentin had a lower VAS pain score than those taking amytriptyline (MD -1.50, 95% CI -2.06 to -0.94, n = 40, low-quality evidence). Study authors reported that no statistically significant difference was observed in the rate of adverse effects among women taking gabapentin compared with women given amytriptyline. The study comparing goserelin versus progestogen did not report on adverse effects. Psychological treatment Women who underwent reassurance ultrasound scans and received counselling were more likely to report improved pain than

Polyuria increases the risk of dehydration and lithium toxicity in lithium-treated patients. Risk factors have been inconsistently described and the variance of this adverse effect remains poorly understood. This study aimed to establish independent risk factors for polyuria in a community, secondary-level lithium-treated sample of patients. This was a cross-sectional study of the lithium-treated patients attending a general adult and an old age psychiatry service. Participants completed a 24-hour urine collection. Urine volume and the presence of polyuria were the outcomes of interest. The relationship between outcome and the participant's demographic and clinical characteristics was explored with univariable and multivariable analysis. A total of 122 participants were included in the analysis, with 38% being diagnosed with polyuria. Female gender and increased body weight independently predicted the presence of polyuria (standardized regression coefficient 1.01 and 0.94, respectively; p = 0.002 and p = 0.003, respectively). Female gender and increased body weight, lithium dose, and duration of lithium treatment independently predicted higher 24-hour urine volumes (standardized regression coefficients 0.693, p < 0.0005; 0.791, p < 0.0005; 0.276, p = 0.043; 0.181, p = 0.034, respectively). Of three different weight metrics, lean body weight was the most predictive. Female gender and increased body weight explain part of the variance of this adverse effect. Both risk factors offer fresh insights into the pathophysiology of this potentially reversible and dangerous adverse effect of lithium treatment. Future research should focus on understanding the differences between the genders and between different body compositions in terms of lithium pharmacokinetics and pharmacodynamics. © 2014 John Wiley & Sons A/S.

Postpartum depression (PPD) affects approximately 15% of mothers, disrupts maternal care, and can represent a form of early life adversity for the developing offspring. Intriguingly, male and female offspring are differentially vulnerable to the effects of PPD. Antidepressants, such as fluoxetine, are commonly prescribed for treating PPD. However, fluoxetine can reach offspring via breast milk, raising serious concerns regarding the long-term consequences of infant exposure to fluoxetine. The goal of this study was to examine the long-term effects of maternal postpartum corticosterone (CORT, a model of postpartum stress/depression) and concurrent maternal postpartum fluoxetine on behavioral, endocrine, and neural measures in adult male and female offspring. Female Sprague-Dawley dams were treated daily with either CORT or oil and fluoxetine or saline from postnatal days 2-23, and offspring were weaned and left undisturbed until adulthood. Here we show that maternal postpartum fluoxetine increased anxiety-like behavior and impaired hypothalamic-pituitary-adrenal (HPA) axis negative feedback in adult male, but not female, offspring. Furthermore, maternal postpartum fluoxetine increased the density of immature neurons (doublecortin-expressing) in the hippocampus of adult male offspring but decreased the density of immature neurons in adult female offspring. Maternal postpartum CORT blunted HPA axis negative feedback in males and tended to increase density of immature neurons in males but decreased it in females. These results indicate that maternal postpartum CORT and fluoxetine can have long-lasting effects on anxiety-like behavior, HPA axis negative feedback, and adult hippocampal neurogenesis and that adult male and female offspring are differentially affected by these maternal manipulations.

Acne and seborrhea (or facial oiliness) are related androgenic skin disorders which affect a high proportion of women after menarche. They can have a negative effect on psychological well-being and social life. Androgens play an important role in the pathogenesis of acne through the stimulation of sebum secretion, increasing sebaceous gland size and possibly through follicular hyperkeratinization. Conversely, estrogens decrease sebum production by suppressing gonadotropin release and androgen production and increasing sex hormone binding globulin production. One of the treatment options for these conditions is hormonal therapy, especially for women who require contraception. The effect of combined oral contraceptives in androgenic skin disorders depends on their estrogen:progestogen balance and on the antiestrogenic activity of the progestogen component. Improved understanding of what women value about oral contraceptives suggests that the choice of product should be tailored as much as possible to the individual. Several combined oral contraceptives containing new-generation progestogens (e.g. desogestrel, gestodene) or progestational antiandrogens (e.g. cyproterone acetate, chlormadinone acetate) have demonstrated efficacy in the treatment of women with acne, although comparisons between trials are difficult because of differing endpoints. Seborrhea has been less well studied, but the few studies that are available show an improvement in women with this condition using combined oral contraceptives.

Full Text Available As little information about the effect of ultra high dilutions of glucocorticoid in reproduction is available in the literature, pregnant female Wistar rats (N=12 were blindly subcutaneously treated during all gestational and lactation period with: dexamethasone 4 mg/kg diluted into dexamethasone 15 cH (mixed; or dexamethasone 4 mg/kg diluted in water; or dexamethasone 15 cH, or vehicle. Parental generation had body weight, food and water consumption monitored. The F1 generation was monitored regarding to newborn development. No birth occurred in both groups treated with dexamethasone 4 mg/kg. After 60 days from birth, 12 male F1 rats were randomly selected from each remaining group and inoculated subcutaneously with 1% carrageenan into the footpad, for evaluation of inflammatory performance. Edema and histopathology of the footpad were evaluated, using specific staining methods, immunohistochemistry and digital histomorphometry. Mothers treated with mixed dexamethasone presented reduced water consumption. F1 rats born to dexamethasone 15 cH treated females presented significant increase in mast cell degranulation, decrease in monocyte percentage, increase in CD18+ PMN cells, and early expression of ED2 protein, in relation to control. The results show that the exposure of parental generation to highly diluted dexamethasone interferes in inflammation modulation in the F1 generation.

Centrally-administered oxytocin promotes preference for familiar objects at a short delay in ovariectomized female rats.

Oxytocin has been previously associated with social attachment behaviors in various species, however, most studies focused on partner preference in the socially-monogamous prairie vole. In these, oxytocin treatment was shown to promote partner preference, such that females receiving either central or pulsatile peripheral administration would spend more time with a familiar male. This behavioral outcome was blocked by oxytocin receptor antagonist treatment. The aim of the current study was to further explore the preference-inducing properties of oxytocin by examining its effects on object preference on ovariectomized female rats. In other words, we assessed whether these effects would apply to objects and if they would be persistent across species. Eight rats were infused with oxytocin into the left ventricle and object preference was assessed at two delays: 30min and 4h. At the 30min delay, oxytocin-treated animals showed preference for the familiar object, whereas saline-treated controls exhibited preference for the novel object. At the 4h delay, both groups showed novel-object preference. Our findings show that oxytocin modulates object preference in the female rat at a shorter delay, similar to the findings from partner-preference studies in the prairie vole, suggesting that the mechanisms driving object preference might be in part similar to those responsible for partner preference.

Examining portrayals of female protagonists by female screenwriters using feminist critical discourse analysis.

Directory of Open Access Journals (Sweden)

Shapiro, B.

2017-07-01

Full Text Available This study explores the portrayals of female protagonists by female screenwriters through feminist critical discourse analysis. Specifically, this study examines the female protagonists in the four Academy-Award winning films Thelma & Louise, The Piano, Lost in Translation, and Juno. By analyzing the roles and behavior of the female protagonists in these four films, I reveal how these female protagonists each experience the Heroine’s Journey, where they transcend their gender constraints and become more independent and empowered. These portrayals by female screenwriters are vital to the off-screen sector of the film industry because of the Social Cognitive Theory of Gender Development and Differentiation, which states that human beings gain knowledge from the messages communicated to them by the media. Therefore, I conclude that the existing gap between female and male screenwriters must be closed to counter the reinforcement of gender roles and stereotypes, as well as ensure that women are inspired, not discouraged, by what they see on screen.

Full Text Available In the last years, hormone consumption has increased exponentially. Because of that, hormone compounds are considered emerging pollutants since several studies have determinted their presence in water influents and effluents of wastewater treatment plants (WWTPs. In this study, a quantitative method for the simultaneous determination of oestrogens (estrone, 17β-estradiol, estriol, 17α-ethinylestradiol, and diethylstilbestrol, androgens (testosterone, and progestogens (norgestrel and megestrol acetate has been developed to determine these compounds in wastewater samples. Due to the very low concentrations of target compounds in the environment, a solid phase extraction procedure has been optimized and developed to extract and preconcentrate the analytes. Determination and quantification were performed by ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS. The method developed presents satisfactory limits of detection (between 0.15 and 9.35 ng·L−1, good recoveries (between 73 and 90% for the most of compounds, and low relative standard deviations (under 8.4%. Samples from influents and effluents of two wastewater treatment plants of Gran Canaria (Spain were analyzed using the proposed method, finding several hormones with concentrations ranged from 5 to 300 ng·L−1.

Background: Total-body iron stores (TBI), which are calculated from serum ferritin and soluble transferrin receptor concentrations, can be used to assess the iron status of populations in the United States. Objective: This analysis, developed to support workshop discussions, describes the distribution of TBI and the prevalence of iron deficiency (ID) and ID anemia (IDA) among toddlers, nonpregnant females, and pregnant females. Design: We analyzed data from NHANES; toddlers aged 12-23 mo (NHANES 2003-2010), nonpregnant females aged 15-49 y (NHANES 2007-2010), and pregnant females aged 12-49 y (NHANES 1999-2010). We used SAS survey procedures to plot distributions of TBI and produce prevalence estimates of ID and IDA for each target population. All analyses were weighted to account for the complex survey design. Results: According to these data, ID prevalences (± SEs) were 15.1% ± 1.7%, 10.4% ± 0.5%, and 16.3% ± 1.3% in toddlers, nonpregnant females, and pregnant females, respectively. ID prevalence in pregnant females increased significantly with each trimester (5.3% ± 1.5%, 12.7% ± 2.3%, and 27.5% ± 3.5% in the first, second, and third trimesters, respectively). Racial disparities in the prevalence of ID among both nonpregnant and pregnant females exist, with Mexican American and non-Hispanic black females at greater risk of ID than non-Hispanic white females. IDA prevalence was 5.0% ± 0.4% and 2.6% ± 0.7% in nonpregnant and pregnant females, respectively. Conclusions: Available nationally representative data suggest that ID and IDA remain a concern in the United States. Estimates of iron-replete status cannot be made at this time in the absence of established cutoffs for iron repletion based on TBI.

GH has a positive impact on growth, bone, and muscle development. The objectives of this study were to demonstrate the effects of GH treatment on regional body composition and bone geometry at final height in patients with juvenile idiopathic arthritis (JIA). In this longitudinal study, parameters of bone mineral density and geometry as well as muscle and fat cross-sectional area (CSA) in the nondominant forearm were recorded using peripheral quantitative computed tomography at yearly intervals until final height in 12 patients (seven females) receiving GH treatment. Data at final height were compared with 13 patients (nine females) with JIA not treated with GH. Patients were treated with GH for a mean of 5.35 +/- 0.7 yr. Correcting for height, total bone CSA (+0.89 +/- 0.5 sd) and muscle CSA (+1.14 +/- 0.6 sd) increased significantly and normalized at final height. Compared with JIA patients without GH at final height, there was a significantly higher muscle CSA and a lower fat CSA in GH-treated patients. Additionally, in relation to total bone CSA, there was significantly more cortical and less marrow CSA in boys with GH treatment. During GH treatment, there was a significant increase and normalization of total bone and muscle CSA at final height. In accordance with an anabolic effect of GH, fat mass stabilized at the lower limit of healthy children. At final height, cortical and marrow CSA, relative to total bone CSA, were normalized in GH-treated patients.

Full Text Available Hodgkin's lymphoma is a disease with a high rate of curability under classic chemo-radiotherapy regimes. Complications due to chemotherapy could include viral reactivation due to chronic lymphopenia. BK virus (BKV is a polyoma virus belonging to the Papovaviridae family with antibody seroprevalences in healthy populations varying from 60% to 80%. Initial infections are asymptomatic usually occur in early childhood, after which the viruses remain latent in the kidneys or urothelium. Reactivation of BKV occurs in individuals with severe immunosuppression during HIV infections, transplantation or, exceptionally, after classical chemotherapy. BKV incidence is approximately 0% to 5% in immunocompetent individuals. Reactivation is associated with nephropathy and haemorrhagic cystitis.

Cisplatin (CP) is a major antineoplastic drug for treatment of solid tumors. CP-induced nephrotoxicity may be gender-related. This is while gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter in the central nervous system that has renoprotective impacts on acute renal injury. This study was designed to investigate the protective role of GABA against CP-induced nephrotoxicity in male and female rats. Sixty Wistar male and female rats were used in eight experimental groups. Both genders received GABA (50 μg/kg/day; i. p.) for 14 days and CP (2.5 mg/kg/day; i. p.) was added from day 8 to the end of the study, and they were compared with the control groups. At the end of the study, all animals were sacrificed and the serum levels of blood urea nitrogen (BUN), creatinine (Cr), nitrite, malondialdehyde (MDA), and magnesium (Mg) were measured. The kidney tissue damage was also determined via staining. CP significantly increased the serum levels of Cr and BUN, kidney weight, and kidney tissue damage score in both genders (PGABA did not attenuate these markers in males; even these biomarkers were intensified in females. Serum level of Mg, and testis and uterus weights did not alter in the groups. However, the groups were significantly different in terms of nitrite and MDA levels. It seems that GABA did not improve nephrotoxicity induced by CP-treated rats, and it exacerbated renal damage in female rats.

The aim of the present study was to explore the potential differences between female and male professional divers with regards to demographics, diving certificates, areas of diving, diving activity and health effects. The Norwegian Labour Inspection Authority's Diving certificate register contains data on all professional inshore divers who have held a certificate at any time since 1980. Forty nine per cent of these divers responded to the "Norwegian diver 2011" questionnaire. Of these divers 64 female and 1327 male divers completed the questionnaire about their professional diving career, certificate, year of onset and the year they stopped diving professionally if they were not still active in the diving industry. The level of general education was higher among female divers. More males than females were fully certified in diving. The mean age was lower among female than male fully certified divers. Fully certified female divers reported a lower total number of dives, shallower dives and diving for a shorter period of time than the male divers. They also had a lower percentage of work within the quay/construction sector and more often worked as teachers/instructors. A lower percentage of fully certified females than males had experienced decompression sickness (16.7% vs. 26.9%). Life-threatening events and psychologically challenging events were less common among females, as were adverse health effects. No such gender differences were seen for divers with a restricted certificate. The fully certified, female professional divers in our study had a very short diving career, reported fewer and shallower dives, and chose less physically demanding jobs than their male counterparts. They also had a higher level of education, reported less health problems and a better quality of life. The health effects seem to be related to the type of work rather than to gender.

The adverse effects of high fat induced obesity on female reproductive cycle and hormones

Donthireddy, Laxminarasimha Reddy

The prevalence of obesity, an established risk and progression factor for abnormal reproductive cycle and tissue damage in female mice. It leads to earlier puberty, menarche in young females and infertility. There are extensive range of consequences of obesity which includes type-2 diabetes, cardiovascular disease and insulin resistance. Obesity is the interaction between dietary intake, genes, life style and environment. The interplay of hormones estrogen, insulin, and leptin is well known on energy homeostasis and reproduction. The aim of this study is to determine the effect of high fat induced obesity on reproductive cycles and its hormonal abnormalities on mice model. Two week, 3 month and 8 month long normal (WT) and very high fat diet (VHFD) diet course is followed. When mice are fed with very high fat diet, there is a drastic increase in weight within the first week later. There was a significant (p<0.001) increase in leptin levels in 6 month VHFD treated animals. 2 week, 3 month and 6 month time interval pap smear test results showed number of cells, length of estrous cycle and phases of the estrous cycle changes with VHFD mice(n=30) compared to normal diet mice(n=10). These results also indicate that the changes in the reproductive cycles in VHFD treated female mice could be due to the changes in hormones. Histo-pathological analyses of kidney, ovary, liver, pancreas, heart and lungs showed remarkable changes in some tissue on exposure to very high fat. Highly deposited fat packets observed surrounding the hepatocytes and nerve cells.

Objectives: The study aimed to explore the lived experiences of MIPs of female rape victims and the meaning of these experiences in the six months following the partner’s rape. Method: We conducted a longitudinal hermeneutic phenomenological study. Nine purposively sampled adult MIPs were interviewed over a period of six months. The participants were in an intimate relationship with a female rape victim prior to and immediately after the rape; their partners had been treated at a specialised centre for victims of rape and sexual assault. Four interviews were conducted with each of the nine intimate partners of female rape victims: (1 within 14 days of, (2 a month after, (3 three months after, and (4 six months after the rape. Results: Two major themes emerged: being-in-the-world as a secondary victim of rape, and living in multiple worlds, those of their female partners, family, friends, society, employers or colleagues, professionals and the justice system. The participant’s familiar world became strange and even threatening, and his relationship with his partner became uncertain. Conclusion: Early supportive intervention for intimate partners of female rape victims is required to prevent on-going emotional trauma and alleviate the effects of chronic post-traumatic stress disorder and suffering at intra- and interpersonal levels.

Full Text Available Abstract Background Female genital tuberculosis is an uncommon disease that is rarely diagnosed in developed countries. Case presentation A 61-year-old postmenopausal woman who had undergone surgery and treated with adjuvant chemotherapy for infiltrating ductal carcinoma of the breast five years ago, presented with bloody vaginal discharge, fatigue, weight loss, and low grade fevers at night for two months. Histological examination of the endometrium, done based on the suspicion of a second primary cancer due to the tamoxifen therapy, revealed a granulomatous reaction. Liquid and solid mycobacterial cultures of the tissues were performed. Although the acid fast staining was negative, the liquid culture was positive for Mycobacterium tuberculosis. Involvement of other systems was not detected. The patient was treated with a three-drug antituberculosis regimen for 9 months and recovered fully. Conclusion Female genital tuberculosis is a rare but curable disease that should be included in the differential diagnosis of women with menstrual problems. Early diagnosis is important and may prevent unnecessary invasive procedures for the patient.

The relative affinity constants for binding of estrone (E 1 ), estriol (E 3 ), 17β-estradiol(E 2 ) and 17α-ethinyl-17β-estradiol(EE 2 ) to cytosol estrogen-receptors of rat hypothalamus and pituitary were estimated by a radioligand-receptor assay procedure. The relative affinity constants in the hypothalamic system were 6.5x10 -10 M for E 2 , 1x10 -9 M for EE 2 and 2x10 -8 M for E 1 and E 3 . The affinity constants were 1x10 -9 M for E 2 and E 3 and 7x10 -9 M for E 1 and E 3 when pituitary cytosol samples were used. Some discrepancies between biological activity and affinity for the estrogen-receptor were noted. These may be due to differences in the metabolism and cellular uptake of the estrogens. The radioligand-receptor assay procedure may be useful in evaluating the action of estrogens and anti-estrogens acting at the hypothalamic and pituitary level. Sedimentation patterns of cytosol samples labelled with the estrogens used in this study revealed, upon ultracentrifugation, protein moieties sedimenting in the 8 S region. The potency of progesterone and D-Norgestrel to modulate the release of LH and FSH stimulated by luteinizing hormone-releasing hormone (LH-RH) in castrated female rats was found to correlate well with the biological activity of the progestogens. It is concluded that the radioligand-receptor assay procedure for estrogens and the in-vivo model for the evaluation of the central action of progestogens may be valuable tools for testing new steroids to be used in oral contraceptives.

Full Text Available Abstract Background Over 300 therapies have been proposed for premenstrual syndrome. To date there has been only one survey conducted in the UK of PMS treatments prescribed by GPs, a questionnaire-based study by the National Association of Premenstrual Syndrome in 1989. Since then, selective serotonin re-uptake inhibitors have been licensed for severe PMS/PMDD, and governmental recommendations to reduce the dosage of vitamin B6 (the first choice over-the-counter treatment for many women with PMS have been made. This study investigates the annual rates of diagnoses and prescribing patterns for premenstrual syndrome (1993–1998 within a computerised general practitioner database. Methods Retrospective survey of prescribing data for premenstrual syndrome between 1993–1998 using the General Practice Research Database for the West Midlands Region which contains information on 282,600 female patients Results Overall the proportion of women with a prescription-linked diagnosis of premenstrual syndrome has halved over the five years. Progestogens including progesterone were the most commonly recorded treatment for premenstrual syndrome during the whole study period accounting for over 40% of all prescriptions. Selective serotonin-reuptake inhibitors accounted for only 2% of the prescriptions in 1993 but rose to over 16% by 1998, becoming the second most commonly recorded treatment. Vitamin B6 accounted for 22% of the prescriptions in 1993 but dropped markedly between 1997 and 1998 to 11%. Conclusions This study shows a yearly decrease in the number of prescriptions linked to diagnoses for premenstrual syndrome. Progestogens including progesterone, is the most widely prescribed treatment for premenstrual syndrome despite the lack of evidence demonstrating their efficacy.

Female detection of the synthetic sex pheromone contributes to the efficacy of mating disruption of the European grapevine moth, Lobesia botrana.

Science.gov (United States)

Harari, Ally R; Zahavi, Tirtza; Steinitz, Hadass

2015-02-01

Studies of the mechanisms by which mating-disruption techniques control insect pest populations have traditionally focused on the effects of the species-specific sex pheromone on the male moths, while neglecting possible direct effects of the pheromone on females. Here, the effects of exposure to synthetic species-specific sex-pheromone on Lobesia botrana (European grapevine moth) females were tested. Females in vineyards that were treated with mating-disruption pheromone burst into short bouts of flying more frequently, but called significantly less frequently than females in untreated plots. Reduced calling caused by exposure to the species-specific sex-pheromone may increase the age at which females mate and thereby reduce female fecundity. Females that called in a pheromone-saturated environment experienced a decrease in number of oviposited eggs. A further decrease in reproductive success may occur if females delay oviposition when exposed to access of the synthetic pheromone. In addition to reducing the ability of males to locate females, the mating-disruption technique can suppress pest numbers as a consequence of its direct effects on females. The two mechanisms probably act synergistically. © 2014 Society of Chemical Industry.

A 4-month-old female infant was diagnosed as bilateral retinoblastoma. The left eye was treated by enucleation and the right by radiation. The right eye received repeated thermochemotherapy, cryocoagulation and photocoagulation for recurrence. Total retinal detachment was detected after surgery for complicated cataract at the age of 2 years 9 months. Vitreous surgery led to the detection of posterior vitreous detachment and retinal breaks in the coagulated scar areas with vitreoretinal adhesion around the calcified tumor. During the following one year, the retina has been attached with no reoccurrence of the tumor. This case illustrates that rhegmatogenous retinal detachment is a possibility in retinoblastoma treated by radiation or retinal coagulations. (author)

Full Text Available Evaluated under laboratory condition. The objective of the present study was to observe the effect of impregnated torn bednets on the number of bites by An. culicifacies A glass made tunnel test was designed to The effect of torn bednets treated with three dosages of cyfluthrin 5% EW, were induce hungry female mosquitoes to pass through holes cut in the pyrethroid treated nets. A guinea pig used as bait to attract mosquitoes through circular holes in the netting. With untreated netting, 72-87% of laboratory-reared females passed through the holes overnight, 64-92% blood-fed successfully and 0.3/9-4/3% died. When the netting was treated with cyfluthrin at doses of 25, 50 and 100 mg a.i./m2, the entry Index (the proportions that passed through the holes overnight were 43.37%, 42.82% and 24.72%; mortality rates were 66.31%, 81.45% and 95.99%; and the feeding rate were 45%, 27% and 3%. In conclusion it should be stressed that efficacy of pyrethroid impregnated bednets using “Tunnel Tests” showing acceptable protection rate both in lower and higher dosages as well as cause dead in the blood-fed mosquitoes. In addition, the higher dosages of these three dosages pyrethroid provided good levels of protection against An. culicifacies.

Online Female Escort Advertisements

Full Text Available Female escorts represent an occupational group that charges a fee for sex, which can be regarded as an extreme form of short-term mating. The present study examined if the fees charged by escorts are related to traits typically associated with female short-term mate value. A total of 2,925 advertisements for female escorts offering sexual services in the United States were examined, as a customized software program was used to download all the advertisements from an online escort directory. The advertisement content was coded, and relationships between advertised physical characteristics and the hourly rate charged by female escorts were examined. The analyses showed that higher fees were associated with female escorts who advertised a waist-to-hip ratio near 0.7, lower weight and body mass index, younger age, and photographic displays of breast and buttocks nudity. The findings provide evidence that evolutionarily relevant traits associated with female short-term mate value are systematically related to fees charged for sexual services.

The wandering glider dragonfly Pantala flavescens migrates to Japan every spring, where the population increases until autumn, in which mass flights often occur, followed by death in the winter. There have been no reports to date on the maturation process of this species throughout its lifespan in Japan. We collected females from mass flights when the flight height was low, and classified them into seven age stages by examining their wing condition. Very few females of the older stage were collected from the mass flights. The wing condition corresponded with the change in body color and with the egg production process in the ovaries. While pre-reproductive-stage females did not release eggs when treated with our artificial oviposition technique, each reproductive-stage female released about 640 eggs. Nearly all eggs released were fertilized. The ovaries developed with the stage, and reproductive-stage females had about 1100 ovarioles. The estimated maximum fecundity was about 29,000 eggs. The lifetime number of eggs laid of P. flavescens should be revealed by dissection.

Effect of tibolone and its principal metabolites (3α- and 3β-hydroxy, 3α-sulfate, and 4-ene derivatives) on estrone sulfatase activity in normal and cancerous human breast tissue.

Tibolone (Org-OD14) is the active substance of Livial®, a synthetic steroid with the structure 7α,17α-17-hydroxy-7-methyl-19-norpregn-5(10)-en-20-yn-3-one, possessing weak tissue-specific estrogenic, progestogenic, and androgenic properties, used to treat menopausal complaints. After oral administration, tibolone is extensively metabolized into the 3α-(Org-4904) and 3β-(Org-30126) hydroxy derivatives with estrogenic properties, its 4-ene (Org-OM38) isomer with progestogenic/androgenic activities, and the 3α-sulfate (Org-34322) derivative, a major biologically inactive circulating form. We compared the dose response of tibolone and its metabolites on estrone sulfatase activity [conversion of estrone sulfate (E1S) to estrone (E1)] in normal and cancerous human breast tissues. Tissue minces were incubated with physiological concentrations of [3H]-E1S (5×10-9M) alone or in the presence of tibolone and its metabolites (concentration range: 5×10-7to 5×10-5M) for 4 h. Tritiated E1, estradiol (E2), and E1S were separated and evaluated quantitatively by thin-layer chromatography. The sulfatase activity was significantly higher in cancerous breast but strongly inhibited by tibolone and the different metabolites, whereas 3α- and 3β-hydroxy derivatives were the most potent inhibitors. This very significant inhibitory effect of tibolone and its principal metabolites on the enzyme involved in E2biosynthesis in the human breast provides interesting perspectives to study the biological responses of these compounds in trials with breast cancer patients.

Effects of tributyltin (TBT) and testosterone on the female genital system in the mesogastropod Littorina littorea (Prosobranchia)

Science.gov (United States)

Deutsch, U.; Fioroni, P.

1996-03-01

Experiments were performed with the mesogastropod Littorina littorea on Helgoland, in Roscoff, and in the laboratory in order to evaluate the reaction of the female genital system to TBT, an environmental toxicant. The snails were either injected with 50 or 100 ng tributyltin (TBT) soluted in ethanol or exposed to artificial sea water treated with 5, 50, 100, and 200 ng TBT/l, and 33 ng testosterone/l. The duration of the experiments was either four or eight weeks. None of the analysed female L. littorea showed signs of imposex. Compared to results for the control groups, the size of the female glandular complex was significantly reduced if the pre-experimental toxication was already high, as is the case in snails collected around Helgoland. TBT-related gland complex reduction occurs also in female L. littorea from other sampling sites. In addition, injection of ethanol also causes a decrease in gland size. The experimental results demonstrate that the distal female genital system responds with significantly lower sensitivity to TBT than that of other prosobranchs. This behaviour is ascribed to the lack of an androgen receptor at the ovipositor. The results further strengthen the case of the extreme rarity of imposex described for female L. littorea in natural habitats. However, strong TBT-toxication may affect L. littorea populations significantly because of increasing masculinization of the females, which reduces reproduction ability.

Full Text Available Maternal Graves’ disease is relatively uncommon with an estimated incidence of 0.4%–1% of all pregnancies, but only 1–5% of newborns delivered to mothers with Graves’ disease develop overt clinical signs and symptoms of hyperthyroidism. Here, we describe a case of a 1380-gram female neonate who was born at 30-week gestation to a mother with Graves’ disease. Our patient presented with hyperthyroidism followed by transient hypothyroidism requiring treatment with levothyroxine. While hyperthyroid, she was treated with methimazole, iodine, and a beta-blocker. 20 days after the initiation of methimazole, she developed neutropenia. The neutrophil counts started to improve immediately after the initiation of the weaning of methimazole. To the best of our knowledge, this is the first case reported in the literature of methimazole induced neutropenia in a preterm infant being treated for neonatal Graves’ disease.

To explore the feasibility and effectiveness of a modified posterior vaginal mesh suspension method in treating female rectocele with intractable constipation. Descriptive study (Canadian Task Force classification II-3). The study was performed in the Study Center for Female Pelvic Dysfunction Disease, Department of Obstetrics and Gynecology, Tongji Hospital, Tongji University School of Medicine, Shanghai, China. The Study Center includes 15 physicians, most of whom have received advanced training in pelvic floor dysfunctional disease and can skillfully perform many types of operations in patients with such disease. Almost 1500 operations to treat pelvic floor dysfunctional disease are performed every year at the center. Thirty-six women with rectocele with intractable constipation. Posterior vaginal mesh suspension. All patients were followed up for 15 to 36 months. In 29 patients, the condition was cured completely; in 5 patients it had improved; and in 2 patients, the intervention had no effect. Insofar as recovery and improved results, the overall effectiveness rate was 94.4%. Posterior vaginal mesh suspension is an effective, harmless, and convenient method for treatment of female rectocele with intractable constipation. It has positive short-term curative effects, with few complications and sequelae. However, the long-term effects of posterior vaginal mesh suspension should be evaluated. Copyright © 2012 AAGL.

There has been increasing interest in the effects of neonicotinoid insecticides on wild bees. In solitary bee species the direct link between each individual female and reproductive success offers the opportunity to evaluate effects on individuals. The present study investigated effects of exposure to winter oilseed rape grown from thiamethoxam-treated seed on reproductive behavior and output of solitary red mason bees (Osmia bicornis) released in 6 pairs of fields over a 2-yr period and confined to tunnels in a single year. After adjustment to the number of females released, there was significantly lower production of cells and cocoons/female in tunnels than in open field conditions. This difference may be because of the lack of alternative forage within the tunnels. Under open field conditions, palynology of the pollen provisions within the nests demonstrated a maximum average of 31% oilseed rape pollen at any site, with Quercus (oak) contributing up to 86% of the pollen. There were no significant effects from exposure to oilseed rape grown from thiamethoxam-treated seed from nest establishment through cell production to emergence under tunnel or field conditions.

Full Text Available Abstract Objectives: To describe the circumstances of inclusion of female nurses in the Second World War through the Brazilian Air Force, and discuss the challenges faced by and the achievements of these nurses. Methods: Socio-historical study developed with textual and photographic sources, in addition to oral sources through interviews with war veterans. Data were treated according to the historical method and discussed with concepts support from the theory of social world, by Pierre Bourdieu. Results: The research has demonstrated that the inclusion of female nurses to the Air Force was characterized by social and symbolic effects of war demands and gender boundaries. Conclusion: The great challenge was the official incorporation of women by the Brazilian Air Forces in the post-war period. For this purpose, the organization of a flight female nurses cadre during the conflict was fundamental. Moreover, the record of this history reiterates the Nursing's legacy and the necessity of preparation for care in chaos situations.

Reproductive behavior and physiology of Dacus oleae: egg hatch in females mated successively with normal and gamma sterilized males and vice versa

Economopoulos, A.P.; Giannakakis, A.; Voyadjoglou, A.V.

1976-01-01

In Dacus oleae (Gmelin), a 2nd mating by an 8-krad gamma ray-sterilized male reduced egg hatch immediately to zero or near-zero in ca. 40-55 percent of individually-tested females. In another 50 percent of females, egg hatch was reduced to between 5 to 70 percent, while in fewer than 10 percent of females, egg hatch showed no change. The above was true for females reared on artificial diet for more than 50 generations and mated with same type males, as well as females reared on olives for 6 to 8 generations and mated first with same type males and 2nd with artificially-reared sterilized males. When the 2nd males were treated at 15 krad the effect on egg hatch was smaller. When the 2nd males were treated at 8 krad and had depleted their sperm, by repeated matings, they produced small or no-effect on egg hatch. When artificially-reared females mated first with a sterilized and second with a normal same type male, egg hatch increased from 0 to 5 percent to 70 to 100 percent in 50 to 55 percent of the cases. In another 43 percent of cases, egg hatch increased to levels between 5 to 70 percent. The combined findings from the 2 mating sequence types are as follows. After females mated first with normal males, egg hatch was above 80 percent in the population; a 2nd mating with 8-krad-sterilized males produced an immediate decrease of egg hatch to ca. 25 percent, decreasing slowly thereafter. When the 1st male was sterilized and the 2nd normal, egg hatch increased to ca. 70 percent, decreasing slowly thereafter

Impulse control disorder behaviors associated with pramipexole used to treat fibromyalgia.

Holman, Andrew J

2009-09-01

Compulsivity has been associated with use of dopamine agonists used to treat Parkinson's disease (PD). Increasing use of these agents to treat fibromyalgia (FM) raises concern for this unexpected toxicity in a new group of patients. This is the first report of compulsive gambling and shopping among patients taking dopamine agonists for treatment of FM. A retrospective chart review of all patients in a large, active FM research practice was used to identify compulsivity associated with dopamine agonists and describe its remission following dug withdrawal. Of 3006 patients with FM treated between 2002 and 2006, 1356 had taken > or =1 dose of a dopamine agonist ( >95% pramipexole). Twenty-one (3 male, 18 female) were identified with compulsive gambling (33%), shopping (40%) or both (27%) after taking a 4.5 mg mean dose of pramipexole at bedtime for 14.4 +/- 14.9 months. Compulsivity resolved in 3-10 days for 19 of 21 patients and by 3 months for all following a monitored, compulsory tapered discontinuation over 7 days. While biologic aspects of PD and FM differ considerably, compulsive gambling and shopping have become important, yet unexpected concerns related to use of dopamine agonists for patients with FM and their treating clinicians.

Life history trade-offs and behavioral sensitivity to testosterone: an experimental test when female aggression and maternal care co-occur.

Directory of Open Access Journals (Sweden)

Kimberly A Rosvall

Full Text Available Research on male animals suggests that the hormone testosterone plays a central role in mediating the trade-off between mating effort and parental effort. However, the direct links between testosterone, intrasexual aggression and parental care are remarkably mixed across species. Previous attempts to reconcile these patterns suggest that selection favors behavioral insensitivity to testosterone when paternal care is essential to reproductive success and when breeding seasons are especially short. Females also secrete testosterone, though the degree to which similar testosterone-mediated trade-offs occur in females is much less clear. Here, I ask whether testosterone mediates trade-offs between aggression and incubation in females, and whether patterns of female sensitivity to testosterone relate to female life history, as is often the case in males. I experimentally elevated testosterone in free-living, incubating female tree swallows (Tachycineta bicolor, a songbird with a short breeding season during which female incubation and intrasexual aggression are both essential to female reproductive success. Testosterone-treated females showed significantly elevated aggression, reduced incubation temperatures, and reduced hatching success, relative to controls. Thus, prolonged testosterone elevation during incubation was detrimental to reproductive success, but females nonetheless showed behavioral sensitivity to testosterone. These findings suggest that the relative importance of both mating effort and parental effort may be central to understanding patterns of behavioral sensitivity in both sexes.

4,4'-Methylenedianiline (4,4'-diaminodiphenylmethane; DAPM) is an aromatic diamine used in the production of numerous polyurethane foams and epoxy resins. Previous studies in rats revealed that DAPM initially injures biliary epithelial cells of the liver, that the toxicity is greater in female than in male rats, and that the toxic metabolites of DAPM are excreted into bile. Since male and female rats exhibit differences in the expression of both phase I and phase II enzymes, our hypothesis was that female rats either metabolize DAPM to more toxic metabolites or have a decreased capacity to conjugate metabolites to less toxic intermediates. Our objective was thus to isolate, characterize, and quantify DAPM metabolites excreted into bile in both male and female bile duct-cannulated Sprague Dawley rats. The rats were gavaged with [ 14 C]-DAPM, and the collected bile was subjected to reversed-phase HPLC with radioisotope detection. Peaks eluting from HPLC were collected and analyzed using electrospray MS and NMR spectroscopy. HPLC analysis indicated numerous metabolites in both sexes, but male rats excreted greater amounts of glutathione and glucuronide conjugates than females. Electrospray MS and NMR spectra of HPLC fractions revealed that the most prominent metabolite found in bile of both sexes was a glutathione conjugate of an imine metabolite of a 4'-nitroso-DAPM. Seven other metabolites were identified, including acetylated, cysteinyl-glycine, glutamyl-cysteine, glycine, and glucuronide conjugates. While our prior studies demonstrated increased covalent binding of DAPM in the liver and bile of female compared to male rats, in these studies, SDS-PAGE with autoradiography revealed 4-5 radiolabeled protein bands in the bile of rats treated with [ 14 C]-DAPM. In addition, these bands were much more prominent in female than in male rats. These studies thus suggest that a plausible mechanism for the increased sensitivity of female rats to DAPM toxicity may be decreased

Methods: The present study investigates, in female Wistar HanUnib rats, the effect of long-term high-fat fed group (HFD compared with standard chow on BP by an indirect tail-cuff method using an electrosphygmomanometer, insulin and glucose function, and kidney function by creatinine and lithium clearances. Results: The current study shows glucose tolerance impairment, as demonstrated by increased fasting blood glucose (ND: ±2.8 vs. HFD: 87±3.8 mg/dL associated with reduced insulin secretion (ND: 0.58±0.07 vs. HFD: 0.40±0.03 ng/mL in 8-week female HFD-treated rats. The incremental area under the curve (AUC, ND: 1,4558.0±536.0 vs. HFD: 1,6507.8±661.9, homeostasis model assessment of insulin resistance (HOMA-IR index, and the first-order rate constant for the disappearance of glucose (Kitt were significantly enhanced in 8-week HFD-treated rats compared with age-matched ND group (respectively, P=0.03, P=0.002, and P<0.0001. The current study also shows a significantly higher systolic BP measured in 5 and 8 weeks posttreatment in HFD (5-week HFD-treated: 155.25±10.54 mmHg and 8-week HFD-treated: 165±5.8 mmHg (P=0.0001, when compared to BP values in 5-week ND, 137±4.24 mmHg and 8-week ND, 131.75±5.8 mmHg age-matched group. Otherwise, the glomerular filtration rate and renal sodium handling evaluated by FENa, FEPNa and FEPPNa, were unchanged in both groups. Conclusion: We may conclude that 8-week female HFD-fed rats compared with ND group stimulate harmful effects, such as BP rise and peripheral glucose intolerance. The increased BP occurs through insulin resistance and supposedly decreased vasodilatation response without any change on renal function.

Full Text Available AbstractObjective(sGastric ulceration is induced by various forms of stress like surgery, ischemia and trauma. The female sex has more resistance to stress and the gastrointestinal lesions happen fewer than male sex. The purpose of this study was to evaluate the role of estradiol and progesterone on the gastric acid and pepsin levels following traumatic brain injury (TBI induction.Materials and MethodsDiffuse TBI was induced by Marmarou method in female rats. Rats randomly assigned into 9 groups: intact, OVX (ovarectomized rat, Sham+OVX, TBI (intact rats under TBI, TBI+OVX (ovarectomized rats under TBI and treated OVX rats with vehicle (sesame oil, E2 (estradiol, P4 (progesterone or E2+P4 combination. The acid content and pepsin levels of each gastric washout sample were measured 5 days after the TBI induction.ResultsThere was no significant difference in gastric acid output between groups either after TBI induction or after treatment with E2 or P4 or E2+P4. Gastric pepsin levels were increased in Sham+OVX, TBI (P< 0.001 and TBI+OVX (P< 0.05 compared to intact group. Gastric pepsin levels were significantly lower in E2 and E2+ P4 treated rats than vehicle treated group (P< 0.01. P4 treatment increased gastric pepsin level compared to TBI+OVX group (P< 0.05 and this increment was higher than rats that were treated with the E2 and E2+P4 (P< 0.01.ConclusionThese results suggest that protective effect of estradiol and E2+P4 combination against mucosal damage after TBI, might be mediated by inhibition of pepsin secretion.

Prenatal exposure of the female sheep to excess testosterone (T) leads to hypergonadotropism, multifollicular ovaries, and progressive loss of reproductive cycles. We have determined that prenatal T treatment delays the latency of the estradiol (E2)-induced LH surge. To extend this finding into a natural physiological context, the present study was conducted to determine if the malprogrammed surge mechanism alters the reproductive cycle. Specifically, we wished to determine if prenatal T treatment 1) delays the onset of the preovulatory gonadotropin surge during the natural follicular phase rise in E2, 2) alters pulsatile LH secretion and the dynamics of the secondary FSH surge, and 3) compromises the ensuing luteal function. Females prenatally T-treated from Day 60 to Day 90 of gestation (147 days is term) and control females were studied when they were approximately 2.5 yr of age. Reproductive cycles of control and prenatally T-treated females were synchronized with PGF2alpha, and peripheral blood samples were collected every 2 h for 120 h to characterize cyclic changes in E2, LH, and FSH and then daily for 14 days to monitor changes in luteal progesterone. To assess LH pulse patterns, blood samples were also collected frequently (each 5 min for 6 h) during the follicular and luteal phases of the cycle. The results revealed that, in prenatally T-treated females, 1) the preovulatory increase in E2 was normal; 2) the latencies between the preovulatory increase in E2 and the peaks of the primary LH and FSH surges were longer, but the magnitudes similar; 3) follicular-phase LH pulse frequency was increased; 4) the interval between the primary and secondary FSH surges was reduced but there was a tendency for an increase in duration of the secondary FSH surge; but 5) luteal progesterone patterns were in general unaltered. Thus, exposure of the female to excess T before birth produces perturbances and maltiming in periovulatory gonadotropin secretory dynamics, but these

Concerns about the potential adverse effectsof endocrine disruptors (EDs) have been increasingover the last three decades. BisphenolA (BPA), genistein (G) and vinclozolin (V) arethree widely used EDs sharing similar effects.Since populations are exposed to many diverseEDs simultaneously, we demonstratedrecently their impact alone or combined onmale rat tooth enamel. The purpose of thisstudy was therefore to assess their effects onfemale rat tooth enamel in order to understandwhy they are differentially sensitive. Ratswere exposed daily in utero and after birth tolow doses of EDs during the critical fetal andsuckling periods when amelogenesis takesplace. Enamel of rats exposed to EDs presentedopaque areas of hypomineralization. Theproportion of affected rats was the highestin the groups of rats treated with BPA aloneand higher in males than in females (in all thegroups). Comparison of enamel key gene expressionlevels showed modulations of Klk4and Enamelin in males but no significant variationsin females. These findings show thatfemale rats are less affected than males bythe three EDs chosen in this study and suggestthat enamel hypomineralization may differbetween males and females.

In mammals, ontogenesis starts from a fusion of spermatozoon and oocyte, which are produced by reductive nuclear division of a diploid germ cell in a specialised but complex biological process known as meiosis. However, little is known about the mechanism of meiotic initiation in germ cells, although many factors may be responsible for meiosis both in male and female gonads. In this study, 11.5 days post coitum (dpc) female fetal mouse genital ridges were cultured in vitro with exposure to Brefeldin A (BFA) for 6h, and the changes in meiosis were detected. Synaptonemal-complex analysis implied that BFA played a positive role in meiosis initiation and this hypothesis was confirmed by quantitative PCR of meiosis-specific genes: stimulated by retinoic acid gene 8 (Stra8) and deleted in a zoospermia-like (DAZL). At the same time, mRNA expression of retinoic acid synthetase (Raldh2) and retinoic acid (RA) receptors increased in female gonads with in vitro exposure to BFA. Transplanting genital ridges treated with BFA into the kidney capsule of immunodeficient mice demonstrated that the development capacity of female germ cells was normal, while formation of primordial follicles was seen to be a result of accelerated meiosis after exposure to BFA. In conclusion, the study indicated that BFA stimulated meiosis initiation partly by RA signalling and then promoted the development of follicles.

There is a controversy regarding the effects of the analogues of the gonadotrophin-releasing hormone (GnRH) in radiotherapy. This has led us to study the possible radio-protection of the ovarian function of a GnRH agonist analogue (GnRHa), triptorelin, in adult, female rats (Rattus norvegicus sp.). The effects of the X-irradiation on the oocytes of ovarian primordial follicles, with and without GnRHa treatment, were compared, directly in the female rats (F 0 ) with reproductive parameters, and in the somatic cells of the resulting foetuses (F 1 ) with cytogenetical parameters. In order to do this, the ovaries and uteri from 82 females were extracted for the reproductive analysis and 236 foetuses were obtained for cytogenetical analysis. The cytogenetical study was based on the data from 22,151 metaphases analysed. The cytogenetical parameters analysed to assess the existence of chromosomal instability were the number of aberrant metaphases (2234) and the number (2854) and type of structural chromosomal aberrations, including gaps and breaks. Concerning the reproductive analysis of the ovaries and the uteri, the parameters analysed were the number of corpora lutea, implantations, implantation losses and foetuses. Triptorelin confers radio-protection of the ovaries in front of chromosomal instability, which is different, with respect to the single and fractioned dose. The cytogenetical analysis shows a general decrease in most of the parameters of the triptorelin-treated groups, with respect to their controls, and some of these differences were considered to be statistically significant. The reproductive analysis indicates that there is also radio-protection by the agonist, although minor to the cytogenetical one. Only some of the analysed parameters show a statistically significant decrease in the triptorelin-treated groups.

Sharkey, L; Mc Nicholas, F

2006-04-01

Selective mutism is a rare social anxiety disorder characterized by a total lack of speech in certain specific situations despite the ability to speak in others. Both genetic and psychosocial factors are thought to be involved in its presentation, persistence, and response to treatment. This case report describes a case of young female monozygotic twins who presented with selective mutism and their treatment spanning a 2-year period. It highlights the strong genetic association along with environmental factors such as social isolation and consequences of maternal social phobia, all contributing to treatment resistance, despite an intensive multimodal biopsychosocial approach. General issues related to the difficulties in treating monozygotic twins are also addressed.

Female sexual arousal in amphibians.

Science.gov (United States)

Wilczynski, Walter; Lynch, Kathleen S

2011-05-01

Rather than being a static, species specific trait, reproductive behavior in female amphibians is variable within an individual during the breeding season when females are capable of reproductive activity. Changes in receptivity coincide with changes in circulating estrogen. Estrogen is highest at the point when females are ready to choose a male and lay eggs. At this time female receptivity (her probability of responding to a male vocal signal) is highest and her selectivity among conspecific calls (measured by her probability of responding to a degraded or otherwise usually unattractive male signal) is lowest. These changes occur even though females retain the ability to discriminate different acoustic characteristics of various conspecific calls. After releasing her eggs, female amphibians quickly become less receptive and more choosy in terms of their responses to male sexual advertisement signals. Male vocal signals stimulate both behavior and estrogen changes in amphibian females making mating more probable. The changes in female reproductive behavior are the same as those generally accepted as indicative of a change in female sexual arousal leading to copulation. They are situationally triggered, gated by interactions with males, and decline with the consummation of sexual reproduction with a chosen male. The changes can be triggered by either internal physiological state or by the presence of stimuli presented by males, and the same stimuli change both behavior and physiological (endocrine) state in such a way as to make acceptance of a male more likely. Thus amphibian females demonstrate many of the same general characteristics of changing female sexual state that in mammals indicate sexual arousal. Copyright © 2010 Elsevier Inc.

Veterinary practitioners frequently encounter disorders of the reproductive system in avian patients. Management of these disorders relies on manipulating reproduction by modifying the environment, diet, and social interactions, and by the use of pharmacologic agents and surgery, with varying levels of success and side effects. An alternative is to use the gonadotropin-releasing hormone (GnRH) agonist deslorelin to suppress the pituitary-gonadal axis. To determine the efficacy of deslorelin in domestic pigeons (Columba livia), male (n = 10) and female (n = 10) birds each were implanted intramuscularly with a single long-acting implant containing 4.7 mg deslorelin. Untreated males (n = 11) and females (n = 10) were used as controls. The baseline serum concentration of luteinizing hormone (LH) was assayed at 7, 28, 56, and 84 days after treatment, and egg production was recorded weekly. In females, deslorelin administration significantly reduced serum LH concentrations compared to pretreatment levels at 7, 28, 56, and 84 days (P < .05). In males, deslorelin significantly reduced LH concentrations at 7, 28, and 56 days (P < .05). Female birds treated with deslorelin laid significantly fewer eggs over the course of the study (mean = 1.46, SEM = 0.84) compared with controls (mean = 5.54, SEM = 0.88). Deslorelin treatment had no discernible effect on body weight. Deslorelin is effective for controlling egg laying in female pigeons for at least 49 days, but further research is required to determine the effects on male fertility and the duration of action in both sexes.

To determine the effects of opium on serum glucose, potassium and sodium in male and female Wistar rat, opium solution (60 mg/kg) injected intraperitoneally and the same volume of distilled water was used as control (7 rats in each group). Blood samples were collected at 0, 30, 60, 120, 240 and 360 minutes after injection from orbit cavity and the values of serum glucose, sodium (Na(+)) and potassium (K(+)) were measured. The data were then analyzed by the repeated measure ANOVA based on sex and case-control group. P opium solution injection, in female rats compared to a control group. However, the male rats had this rise at 30, 60 and 120 minutes after opium solution injection compared to control group. While serum glucose in male rats was significantly higher than females at 30, 60 and 120 minutes, this value was higher in the female rats at 360 minutes. Therefore, serum glucose alterations following opium injection was significantly different in groups and in the sexes at different times. Sodium (Na(+)) rose at 60, 240 and 360 minutes significantly in all rats compared to control group. However, sodium alteration following opium injection was significantly different only between treated and control groups but sex-independent at all times. Potassium (K(+)) increased significantly at 60, 120, 240 and 360 minutes in male rats, compared to a control group. In female rats K(+) significantly raised at 30, 120, 240 and 360 minutes. Therefore, the alteration of K(+) in male and female rats was found time dependent and sex independent. According to our results, opium increased serum glucose in male and female rats differently, and it interferes with metabolic pathways differently on a gender dependent basis. Opium raised serum Na(+) and K(+), thus it interfere with water regulation and blood pressure via different mechanism.

Diet-to-female and female-to-pup isotopic discrimination in South American sea lions.

The use of accurate, species-specific diet-tissue discrimination factors is a critical requirement when applying stable isotope mixing models to predict consumer diet composition. Thus, diet-to-female and female-to-pup isotopic discrimination factors in several tissues for both captive and wild South American sea lions were estimated to provide appropriate values for quantifying feeding preferences at different timescales in the wild populations of this species. Stable carbon and nitrogen isotope ratios in the blood components of two female-pup pairs and females' prey muscle from captive individuals were determined by elemental analyzer/isotope ratio mass spectrometry (EA/IRMS) to calculate the respective isotopic discrimination factors. The same analysis was carried out in both blood components, and skin and hair tissues for eight female-pup pairs from wild individuals. Mean diet-to-female Δ(13) C and Δ(15) N values were higher than the female-to-pup ones. Pup tissues were more (15) N-enriched than their mothers but (13) C-depleted in serum and plasma tissues. In most of the tissue comparisons, we found differences in both Δ(15) N and Δ(13) C values, supporting tissue-specific discrimination. We found no differences between captive and wild female-to-pup discrimination factors either in Δ(13) C or Δ(15) N values of blood components. Only the stable isotope ratios in pup blood are good proxies of the individual lactating females. Thus, we suggest that blood components are more appropriate to quantify the feeding habits of wild individuals of this species. Furthermore, because female-to-pup discrimination factors for blood components did not differ between captive and wild individuals, we suggest that results for captive experiments can be extrapolated to wild South American sea lion populations.

Hepatic hereditary telangiectasia in 2 females was treated with hepatic artery embolization. In one patient both peripheral and central arterial occlusion was performed; the patient died of massive gastro-intestinal bleeding 2 months later. Autopsy showed extensive regions with necrosis in the right liver lobe. In the next patient only central occlusion of the right hepatic artery was performed and the arterio-venous shunting in the left liver lobe left remaining. After a long reconvalescence period the patient recovered completely. It is advocated to centrally occlude only that hepatic artery supplying the most affected parts of the liver in Osler's disease. Thus extensive necrosis with possible ensuing death may be avoided.

More than 60% of children with acute myeloid leukemia (AML) become long-term survivors. Most are cured using chemotherapy without hematopoietic stem cell transplantation (HSCT). We report on pubertal development and compare self-reported parenthood among AML survivors and their siblings. We included 137 children treated for AML according to the Nordic Society of Pediatric Hematology and Oncology (NOPHO)-AML-84, -88, and -93 trials, who were alive by June 2007. Patients with relapse or treated with HSCT were excluded. AML survivors participated in a physical and biochemical examination (n = 102) and completed a questionnaire (n = 101). One of their siblings completed an identical questionnaire (n = 84). At a median follow-up of 11 years (range 5-25) after diagnosis of AML the survivors (median age 16 years, range 5-36) were either prepubertal or had entered puberty normally. Serum levels of FSH, LH, testosterone, estradiol, sex hormone binding globulin (SHBG), inhibin A and B, and testicular volumes were within normal ranges. Anti-Müllerian hormone (AMH) levels were decreased in 5 of 40 postpubertal females. Mean reported age at menarche was 13.1 (range 11-17) years. Among survivors 15 years of age or older 31% of females reported pregnancies and 9% of males reported pregnancies in their partners, rates comparable with the frequency reported by their siblings. Most AML survivors treated with chemotherapy had normal pubertal development and fertility, however, AMH levels were decreased in 13% of postpubertal females. Longer follow-up is necessary to evaluate possible risk of premature ovarian failure. © 2013 Wiley Periodicals, Inc.

BaP is a carcinogenic polycyclic aromatic hydrocarbon (PAH) and a common environmental pollutant. Show Racer and White Carneau female pigeons injected weekly with BaP for 3 for 5 months were completely infertile, with ovaries appearing necrotic or oxidized. Fertility in benzo(e)pyrene (BeP, a noncarcinogenic PAH) treated birds was the same as for corn oil treated controls, as was embryo development. Thus, infertility in BaP treated birds appears to be related to its structure-carcinogenic potential. There was no readily apparent affect of BaP treatment on testes from male birds. In order to determine whether BaP metabolites covalently bind to DNA in the ovaries of these birds, pigeons were injected with BaP or BeP, controls were injected with corn oil. Animals were sacrificed 24h later, the ovaries or testes removed, and the DNA isolated and analyzed for PAH-DNA adducts by {sup 32}P-post labeling assay. One major and one minor PAH-DNA adduct was found in ovaries and testes from BaP treated birds. However, no PAH adducts were found in BeP treated or control animals. Thus, problems with fertility may arise because of the alteration in DNA by BaP metabolite binding in ovaries where rapid cell growth occurs during egg production.

Previous studies have demonstrated that female gender could be a prognostic factor in limited-disease (LD) small-cell lung cancer (SCLC), but the correlation between patient gender and survival parameters remains unclear. Data from 179 LD SCLC patients treated with definitive chemoradiotherapy (CRT) were reviewed. Influence of patient gender on time to progression (TTP), local control (LC), brain metastasis-free (BMFS), distant metastasis-free (DMFS) and overall survival (OS) was analysed. Definitive CRT was completed by 179 (110 men/69 women) patients. Of these, 68 (38%; 34 men/34 women) patients were treated in concurrent and 111 (62%; 76 men/35 women) in sequential mode. Prophylactic cranial irradiation (PCI) was subsequently applied in 70 (39%; 36 men/34 women) patients with partial or complete response after CRT. Median OS was 20 (95% confidence interval [CI] 10-22) and 14 (95% CI 10-18) months in female and male patients, respectively (p = 0.021). In subgroups defined by remission status (complete and partial response) after CRT, an OS benefit for females compared to males was also detected. There was no correlation between patient gender and TTP, LC or DMFS, and no difference in OS in the female and male subgroups treated with PCI. The incidence of metachronous brain metastases (BMs) in the male and female subgroups differed significantly (40/110 men vs. 18/69 women, p = 0.03). Also, mean BMFS was significantly longer in women (p = 0.023). Patient gender also significantly correlated with OS on multivariate analysis after adjustment for other prognostic factors (p = 0.04, HR 1.38, 95% CI 1.08-1.92). In this heterogeneous LD SCLC patient cohort treated with definitive CRT, female gender was significantly associated with longer BMFS and OS, as well as with a lower incidence of metachronous brain failure.

A personal best marathon time has been reported as a strong predictor variable for an Ironman race time in recreational female Ironman triathletes. This raises the question whether recreational female Ironman triathletes are similar to recreational female marathoners. We investigated similarities and differences in anthropometry and training between 53 recreational female Ironman triathletes and 46 recreational female marathoners. The association of anthropometric variables and training characteristics with race time was investigated using bi- and multi-variate analysis. The Ironman triathletes were younger (P marathoners. Overall weekly training hours were higher in the Ironman triathletes (P marathoners (P marathon split time for the Ironman triathletes (P = 0.01) and to marathon race time for the marathoners (P = 0.01). To conclude, although personal best marathon time is a strong predictor variable for performance in recreational female Ironman triathletes, there are differences in both anthropometry and training between recreational female Ironman triathletes and recreational female marathoners and different predictor variables for race performance in these two groups of athletes. These findings suggest that recreational female Ironman triathletes are not comparable to recreational female marathoners regarding the association between anthropometric and training characteristics with race time.

Full Text Available In order to study the effect of male on reproductive behavior of female goats, 88 Markhoz breed goats with initial body weight of 42±2kg, 3.5 year old, and 10 male goats were used for 6 weeks. This study was conducted in two phases. In the first experiment 48 female goats were allocated in three groups, each group included eight animals with 2 replicate on both sides of male goats, respectively, at intervals of 0-5, 10-15 and 25-30 meters. In the second experiment, 24 female goats having CIDR were used in an order similar to that of first group. However, the goats were located only in one side of the males. The third group was the control group which was treated in a separate saloon in two groups, each of them having eight animals in it. Results showed a significant effect of male animal in estrus synchronization, the earlier beginning of the reproductive cycle and fertility in the early reproductive season. The first group showed better results in creation and synchronization of estrus in comparison to CIDR received animals (respectively 116.7 vs. 91.6%.

Full Text Available Rat somatosensory cortex contains a large sexually monomorphic genital representation. Genital cortex undergoes an unusual 2-fold expansion during puberty. Here, we investigate genital cortex development and female rat sexual maturation. Ovariectomies and estradiol injections suggested sex hormones cause the pubertal genital cortex expansion but not its maintenance at adult size. Genital cortex expanded by thalamic afferents invading surrounding dysgranular cortex. Genital touch was a dominant factor driving female sexual maturation. Raising female rats in contact with adult males promoted genital cortex expansion, whereas contact to adult females or nontactile (audio-visual-olfactory male cues did not. Genital touch imposed by human experimenters powerfully advanced female genital cortex development and sexual maturation. Long-term blocking of genital cortex by tetrodotoxin in pubescent females housed with males prevented genital cortex expansion and decelerated vaginal opening. Sex hormones, sexual experience, and neural activity shape genital cortex, which contributes to the puberty promoting effects of sexual touch.

Studies have highlighted differences in the victim choice, offender, and offense characteristics of female and male sexual offenders. However, little is known about how solo and co-offending females differ from solo male sexual offenders. We compared the characteristics of 20 solo and 20 co-offending females (co-offended with a male and/or female accomplice), and 40 male sexual offenders against children. We found that solo female offenders showed the most evidence of personal problems, including depression and sexual dissatisfaction. Compared with male offenders, female co-offenders showed poorer self-management, but better sexual self-regulation. Male offenders had a greater history of offending and showed more evidence of sexual abuse supportive cognitions relative to both solo and co-offending females. These results are consistent with the need for a gender-specific approach to working with sexual offenders and may have implications for understanding the often complex treatment needs of these clients.

Bare-part color in female budgerigars changes from brown to structural blue following testosterone treatment but is not strongly masculinized.

Full Text Available Whereas several studies have shown that experimentally increased levels of the androgenic steroid testosterone can affect female behavior, fewer studies have focused on the activational effects of exogenous testosterone on female morphology. With respect to colorful displays in birds, almost exclusively the effects of testosterone manipulation on female carotenoid-based colorations have been studied. Other color types such as structural colors (i.e. UV, blue and violet colors that result from differential light reflection in the nanostructures of the tissue remain largely unstudied. Here, we investigated the short- and long-term effects of exogenous testosterone on the expression of structural bare-part coloration in female budgerigars, Melopsittacus undulatus. In this parrot species, bare-part coloration is expressed in the cere, a structure over the beak which is brown in females and structural blue in males. We experimentally increased plasma testosterone levels in testosterone-treated females (T-females compared to controls (C-females and we performed weekly spectrophotometric measurements of the cere for five weeks after implantation and one measurement after ten weeks. We also estimated the extent to which testosterone masculinized female cere color by comparing the experimental females with untreated males. We found significant effects of testosterone on cere color from week four after implantation onwards. T-females expressed significantly bluer ceres than C-females with higher values for brightness and UV reflectance. T-female cere color, however, remained significantly less blue than in males, while values for brightness and UV reflectance were significantly higher in T-females than in males. Our quantitative results show that exogenous testosterone induces the expression of structural blue color in females but does not strongly masculinize female cere coloration. We provide several potential pathways for the action of testosterone on

Full Text Available The pollution of endocrine disruptors and its impact on human reproductive system have attracted much attention. Di-(2-ethylhexyl phthalate (DEHP, an environmental endocrine disruptor, is widely used in food packages, containers, medical supplies and children’s toys. It can cause diseases such as infertility, sexual precocity and uterine bleeding and thus arouse concerns from the society and scholars. The effect of DEHP on pubertal female reproductive system is still not well-studied. This study was to investigate the effects of DEHP on the hypothalamus–uterus in pubertal female rats, reveal the reproductive toxicity of DEHP on pubertal female rats and its mechanism, and provide scientific evidence for the evaluation of toxicity and toxic mechanism of DEHP on reproductive system. Forty-eight pubertal female rats were randomly divided into four groups and respectively administered via oral gavage 0, 250, 500, or 1000 mg/kg/d DEHP in 0.1 mL corn oil/20 g body weight for up to four weeks. Compared with control rats, the DEHP-treated rats showed: (1 higher gonadotropin-releasing hormone (GnRH level in the hypothalamus; (2 higher protein levels of GnRH in the hypothalamus; and (3 higher mRNA and protein levels of GnRH receptor (GnRHR in the uterus. Our data reveal that DEHP exposure may lead to a disruption in pubertal female rats and an imbalance of hypothalamus–uterus. Meanwhile, DEHP may, through the GnRH in the hypothalamus and its receptor on the uterus, lead to diseases of the uterus. DEHP may impose a negative influence on the development and functioning of the reproductive system in pubertal female rats.

The angiotensin 1-7 (Ang 1-7), is abundantly produced in kidneys and antagonizes the function of angiotensin II through Mas receptor (MasR) or other unknown mechanisms. In the current study, the role of MasR and steroid hormone estrogen on renal blood flow response to Ang 1-7 administration was investigated in ovariectomized (OV) female rats. OV female Wistar-rats received estradiol (500 μg/kg/week) or vehicle for two weeks. In the day of the experiment, the animals were anesthetized, cannulated, and the responses including mean arterial pressure, renal blood flow (RBF), and renal vascular resistance at the constant level of renal perfusion pressure to graded infusion of Ang 1-7 at 0, 100 and 300 ng/kg/min were determined in OV and OV estradiol-treated (OVE) rats, treated with vehicle or MasR antagonist; A779. RBF response to Ang 1-7 infusion increased dose-dependently in vehicle (Pdose <0.001) and A779-treated (Pdose <0.01) animals. However, when MasR was blocked, the RBF response to Ang 1-7 significantly increased in OV animals compared with OVE rats (P<0.05). When estradiol was limited by ovariectomy, A779 increased RBF response to Ang 1-7 administration, while this response was attenuated in OVE animals.

Female mice deficient in alpha-fetoprotein show female-typical neural responses to conspecific-derived pheromones.

Directory of Open Access Journals (Sweden)

Olivier Brock

Full Text Available The neural mechanisms controlling sexual behavior are sexually differentiated by the perinatal actions of sex steroid hormones. We recently observed using female mice deficient in alpha-fetoprotein (AFP-KO and which lack the protective actions of AFP against maternal estradiol, that exposure to prenatal estradiol completely defeminized the potential to show lordosis behavior in adulthood. Furthermore, AFP-KO females failed to show any male-directed mate preferences following treatment with estradiol and progesterone, indicating a reduced sexual motivation to seek out the male. In the present study, we asked whether neural responses to male- and female-derived odors are also affected in AFP-KO female mice. Therefore, we compared patterns of Fos, the protein product of the immediate early gene, c-fos, commonly used as a marker of neuronal activation, between wild-type (WT and AFP-KO female mice following exposure to male or estrous female urine. We also tested WT males to confirm the previously observed sex differences in neural responses to male urinary odors. Interestingly, AFP-KO females showed normal, female-like Fos responses, i.e. exposure to urinary odors from male but not estrous female mice induced equivalent levels of Fos protein in the accessory olfactory pathways (e.g. the medial part of the preoptic nucleus, the bed nucleus of the stria terminalis, the amygdala, and the lateral part of the ventromedial hypothalamic nucleus as well as in the main olfactory pathways (e.g. the piriform cortex and the anterior cortical amygdaloid nucleus, as WT females. By contrast, WT males did not show any significant induction of Fos protein in these brain areas upon exposure to either male or estrous female urinary odors. These results thus suggest that prenatal estradiol is not involved in the sexual differentiation of neural Fos responses to male-derived odors.

Full Text Available Similar to women with Polycystic Ovary Syndrome (PCOS, female sheep treated prenatally with testosterone (T-females are hypergonadotropic, exhibit neuroendocrine defects, multifollicular ovarian morphology, hyperinsulinemia and cycle defects. Hypergonadotropism and multifollicular morphology may in part be due to developmentally regulated increase in pituitary responsiveness to GnRH and may culminate in increased ovarian estradiol production. In this study, we utilized a GnRH agonist, leuprolide, to determine the developmental impact of prenatal testosterone exposure on pituitary-gonadal function and to establish if prenatal exposure produces changes in the reproductive axis similar to those described for women with PCOS. Eight control and eight T-females were injected intravenously with 0.1 mg of leuprolide acetate per kilogram of body weight at 5, 10 and 20 weeks of age. Blood samples were collected by means of an indwelling jugular vein catheter at 0, 3, 6, 9, 12, 18, 24, 30, 36, 42 and 48 hours after leuprolide. Area under the curve (AUC of LH response to leuprolide increased progressively between the three ages studied (P<0.05. AUC of LH in T-females was higher than in control females of the same age at 5 and 10 weeks of age (P<0.05, but similar at 20 weeks of age. AUC of estradiol response was lower at 10 but higher at 20 weeks of age in T-females compared to controls of the same age (P<0.05. Our findings suggest that prenatal T treatment alters the pituitary and ovarian responsiveness in a manner comparable to that observed in women with PCOS.

Sexual violence in South Africa is a major public health and social problem. Sexual assault or rape is a traumatic event which disrupts not only the life of the female rape victim, but also that of her male intimate partner (MIP), irrespective of whether he witnessed or was informed of the incident. The study aimed to explore the lived experiences of MIPs of female rape victims and the meaning of these experiences in the six months following the partner's rape. We conducted a longitudinal hermeneutic phenomenological study. Nine purposively sampled adult MIPs were interviewed over a period of six months. The participants were in an intimate relationship with a female rape victim prior to and immediately after the rape; their partners had been treated at a specialised centre for victims of rape and sexual assault. Four interviews were conducted with each of the nine intimate partners of female rape victims: (1) within 14 days of, (2) a month after, (3) three months after, and (4) six months after the rape. Two major themes emerged: being-in-the-world as a secondary victim of rape, and living in multiple worlds, those of their female partners, family, friends, society, employers or colleagues, professionals and the justice system. The participant's familiar world became strange and even threatening, and his relationship with his partner became uncertain. Early supportive intervention for intimate partners of female rape victims is required to prevent on-going emotional trauma and alleviate the effects of chronic post-traumatic stress disorder and suffering at intra- and interpersonal levels.

Arcuate neurons that coexpress kisspeptin (Kiss1), neurokinin B (Tac2), and dynorphin (Pdyn) mediate negative feedback of 17β-estradiol (E2) on the HPG axis. Previous studies report that fasting and caloric restriction reduce Kiss1 expression. The objective of this study was to determine the interactions of E2 with fasting, caloric restriction, and diet-induced obesity on KNDy gene and receptor expression. Ovariectomized female mice were separated into control and estradiol benzoate (E2B)-treated groups. E2B decreased Kiss1 and the tachykinin 2 receptor, Tac3r, in ARC tissue and Tac2 in Tac2 neurons. Diet-induced obesity decreased Kiss1 in oil-treated animals and the kisspeptin receptor, Kiss1r and Tac3r in the ARC of E2B-treated animals. Chronic caloric (30%) restriction reduced all three neuropeptides in oil-treated females and Kiss1r by E2B in CR animals. Taken together, our experiments suggest that steroidal environment and energy state negatively regulate KNDy gene expression in both ARC and Tac2 neurons. PMID:27507595

Modifying effects of dietary administration of conjugated fatty acids from safflower oil (CFA-S), rich in conjugated linoleic acid, on major organs were examined in the post-initiation stage of a two-stage carcinogenesis model in female rats. Groups of 21 or 22 F344 female rats were treated sequentially with 2,2'-dihydroxy-di-n-propylnitosamine (intragastrically, i.g.), 7,12-dimethylbenz[a]anthracene (i.g.), 1,2-dimethylhydrazine (subcutaneously) and N-butyl-N-(4-hydroxybutyl)nitrosamine (in drinking water) during the first 3 weeks for initiation, and then administered diet containing 1 or 0.1% CFA-S for 33 weeks. Further groups of animals were treated with carcinogens or 1% CFA-S alone, or maintained as non-treated controls. All surviving animals were killed at week 36, and major organs were examined histopathologically for development of pre-neoplastic and neoplastic lesions. The 1 and 0.1% CFA-S treatment significantly decreased the incidence and multiplicity of mammary carcinomas, though a clear dose response was not observed. In the urinary bladder, the incidence of papillary or nodular hyperplasia but not tumors was significantly increased in the 1% CFA-S-treated group. The results indicate that low dose CFA-S may find application as a potent chemopreventor of mammary carcinogenesis.

Radiotherapy and chemotherapy can effectively control cancer but can also cause new second cancers to develop as long-term complications especially in childhood cancer. We experienced two patients with second malignant solid neoplasm who had been treated with radiation and chemotherapy for childhood cancers. One female patients with rhabdomyosarcoma of the right popliteal fossa was treated with radiotherapy at total dose of 54 Gy. Three years and seven months later, osteosarcoma developed in the field of radiation therapy. The other male patient with non-Hodgkin's lymphoma of the small bowel was treated with radiotherapy and leiomyosarcoma developed in the field of radiotherapy 18 years later. We reviewed the literature of the second malignant neoplasm in children in respect of risk factors. The risk for a second primary cancer following radiotherapy or chemotherapy emphasizes the need for life long follow-up of patients receiving such treatments. Particularly patients treated for childhood cancers

Data about physiological performance of female ironman triathletes are rare. However, some studies have reported this endurance sport may cause damage to the right or left ventricles, even in females. The goal of this study was to assess prospectively the right/left ventricular function and physiological performance in female athletes (middle- and long ironman distance) and to compare the findings to female federal police officers. A total of 33 female triathletes and 37 female police officers were examined using spiro-ergometry and echocardiography. Female triathletes achieved VO2max 52.8 ± 5.7 ml/kg(-1)·min(-1), and police officers 35.3 ± 6.5 ml/kg(-1)·min(-1) In athletes, left ventricular end-diastolic diameter was 4.4 ± 0.3 cm and in police officers 4.5 ± 0.4 cm, and the left ventricular muscle mass index was 85.8 g/m(2 )± 18.7 in athletes and in police officers 72.0 g/m(2 )± 9.1. Right ventricular area change among athletes was 49.4 ± 8.5%, and in police officers 46.0 ± 6.9%. The performance date of female triathletes can be used as training prescription for leisure female triathletes, when middle or long distances in triathlon competitions are planned. No right or left ventricular dysfunction was found despite long training and finishing of long distance competitions: non-elite athletes, 5.4 ± 2.8 years of triathlon competitions; elite athletes, 7.6 ± 5.8 years. © The Author(s) 2016.

Women with polycystic ovary syndrome often manifest insulin resistance. Using a sheep model of polycystic ovary syndrome-like phenotype, we explored the contribution of androgen and insulin in programming and maintaining disruptions in insulin signaling in metabolic tissues. Phosphorylation of AKT, ERK, GSK3beta, mTOR, and p70S6K was examined in the liver, muscle, and adipose tissue of control and prenatal testosterone (T)-, prenatal T plus androgen antagonist (flutamide)-, and prenatal T plus insulin sensitizer (rosiglitazone)-treated fetuses as well as 2-yr-old females. Insulin-stimulated phospho (p)-AKT was evaluated in control and prenatal T-, prenatal T plus postnatal flutamide-, and prenatal T plus postnatal rosiglitazone-treated females at 3 yr of age. GLUT4 expression was evaluated in the muscle at all time points. Prenatal T treatment increased mTOR, p-p70S6K, and p-GSK3beta levels in the fetal liver with both androgen antagonist and insulin sensitizer preventing the mTOR increase. Both interventions had partial effect in preventing the increase in p-GSK3beta. In the fetal muscle, prenatal T excess decreased p-GSK3beta and GLUT4. The decrease in muscle p-GSK3beta was partially prevented by insulin sensitizer cotreatment. Both interventions partially prevented the decrease in GLUT4. Prenatal T treatment had no effect on basal expression of any of the markers in 2-yr-old females. At 3 yr of age, prenatal T treatment prevented the insulin-stimulated increase in p-AKT in liver and muscle, but not in adipose tissue, and neither postnatal intervention restored p-AKT response to insulin stimulation. Our findings provide evidence that prenatal T excess changes insulin sensitivity in a tissue- and development-specific manner and that both androgens and insulin may be involved in the programming of these metabolic disruptions. © 2016 by the Society for the Study of Reproduction, Inc.

Full Text Available When compared with other domestic animals the equine species is that present the minors reproductive indices. Besides some parameters of estrous cycle are variable to we consider each mare individually, what hinders the reproductive handling, these females respond the alterations of seasonality, this fact limits in reproduction its potential. Therefore, the uses of innovative reproductive biotechnologies and hormonal protocols have shown indispensable for the producers who wish to increase the reproductive rate of this species. Hormontherapy has shown great efficiency in handling the estrous cycle of these females. Thus, this literature review aimed to perform an update regarding hormonal protocols used in the equine species. Dealt with the main hormones used to control the estrous cycle of mares, as prostaglandin F2a (PGF2α, estrogens, progestogens, human chorionic gonadotropin (hCG, the gonadotropin-releasing hormone (GnRH, equine pituitary extract (EPE, the purified equine follicle stimulating hormone (eFSH and oxytocin. It became evident that the knowledge of hormontherapy applied in equine reproduction is of utmost importance, allowing higher profitability by improving the reproductive efficiency of animals of high genetic value, generating benefits for both the professional as to the owner

2018-05-01

Full Text Available Over the last years, heavy ethanol consumption by teenagers/younger adults has increased considerably among females. However, few studies have addressed the long-term impact on brain structures’ morphology and function of chronic exposure to high ethanol doses from adolescence to adulthood in females. In line with this idea, in the current study we investigated whether heavy chronic ethanol exposure during adolescence to adulthood may induce motor impairments and morphological and cellular alterations in the cerebellum of female rats. Adolescent female Wistar rats (35 days old were treated with distilled water or ethanol (6.5 g/kg/day, 22.5% w/v during 55 days by gavage. At 90 days of age, motor function of animals was assessed using open field (OF, pole, beam walking and rotarod tests. Following completion of behavioral tests, morphological and immunohistochemical analyses of the cerebellum were performed. Chronic ethanol exposure impaired significantly motor performance of female rats, inducing spontaneous locomotor activity deficits, bradykinesia, incoordination and motor learning disruption. Moreover, histological analysis revealed that ethanol exposure induced atrophy and neuronal loss in the cerebellum. These findings indicate that heavy ethanol exposure during adolescence is associated with long-lasting cerebellar degeneration and motor impairments in female rats.

Assessment of several clinical factors on progression-free (PFS) and overall survival (OS) in NSCLC patients (pts.) (stage IV) with mutated epidermal growth factor receptor (EGFRm+) treated with gefitinib (gef) or with chemotherapy (CT) under real-world conditions. 285 EGFRm+ pts. of the non-interventional REASON study treated with gef (n = 206) or CT (n = 79) as first-line therapy or with gef (n = 213) or CT (n = 61) in any line throughout the course of therapy were analyzed according to age, gender, smoking history and histology. Compared with CT, patients treated with gef showed prolongation of PFS and OS in all subgroups. PFS was significantly increased in women and non-smokers. OS was significantly increased in women, non-smokers, (ex)-smokers, patients with adenocarcinoma and elderly patients when treated with gef compared to CT. Female gender turned out to be an independent positive predictive factor for OS in patients treated with gef (HRmale: 1.74, p = 0.0009). A clinical benefit of gef was shown for all analyzed clinical subgroups of EGFRm+ pts. This was confirmed for the female gender in a multivariate analysis. © Georg Thieme Verlag KG Stuttgart · New York.

Rapid and acute effects of estrogen on time perception in male and female rats

Full Text Available Sex differences in the rapid and acute effects of estrodiol on time perception were investigated in adult male and female Sprague-Dawley rats. Because estrodiol has been shown to increase striatal dopamine release, it may be able to modify time perception and timed performance by increasing the speed of an internal clock in a manner similar to indirect dopamine agonists such as amphetamine and cocaine. Two groups of females (neonatally estradiol-treated/adult ovariectomized and neonatally oil-treated/adult ovariectomized and 2 groups of males (neonatally castrated and adult castrated were trained in a 2 s vs. 8 s duration bisection procedure and tested using intermediate signal durations. After obtaining oil-injected baseline psychometric functions over several days, rats were administered 5μg of estradiol for 4 days and behaviorally evaluated 30 min following each injection. This oil-estradiol administration cycle was subsequently repeated 3 times following the re-establishment of baseline training. Results revealed significant sex differences in the initial baseline functions that were not modifiable by organizational hormones, with males’ duration bisection functions shifted horizontally to the left of females’. Upon the first administration of estradiol, females, but not males, showed a significant, transient leftward shift in their bisection functions, indicative of an increase in clock speed. After extensive retraining in the duration bisection procedure, rats that were exposed to gonadal hormones during the first week of life showed a significant rightward shift in their bisection functions on the fourth day of estradiol administration during each cycle, suggesting a decrease in clock speed. Taken together, our results support the view that there are multiple mechanisms of estrogens’ action in the striatum that modulate dopaminergic activity and are differentially organized by gonadal steroids during early brain development.

2008-01-01

Endocrine disruptor exposure during gonadal sex determination was previously found to induce male rat adult onset transgenerational disease (F1–F4 generation), and this was associated with an alteration in the epigenetic (i.e., DNA methylation) programming of the male germ line. The current study was designed to characterize the transgenerational disease phenotypes of the female adult offspring. Pregnant rats (F0 generation) were treated transiently with vinclozolin (i.e., fungicide with anti...

Longitudinal cohort study. To compare functional outcomes between male and female patients before and after surgery for adolescent idiopathic scoliosis (AIS). There is no clear consensus in the existing literature with respect to sex differences in functional outcomes in the surgical treatment of AIS. A prospective, consecutive, multicenter database of patients who underwent surgical correction for adolescent idiopathic scoliosis was analyzed retrospectively. All patients completed Scoliosis Research Society-30 (SRS-30) questionnaires before and 2 years after surgery. Patients with previous spine surgery were excluded. Data were collected for sex, age, Risser grade, previous bracing history, maximum preoperative Cobb angle, curve correction at 2 years, and SRS-30 domain scores. Paired sample t tests were used to compare preoperative and postoperative scores within each sex. Independent sample t tests were used to compare scores between sexes. A P value of Self-image/appearance had the greatest relative improvement. Males had better self-image/appearance scores preoperatively, better pain scores at 2 years, and better mental health and total scores both preoperatively and at 2 years. Both males and females were similarly satisfied with surgery. Males treated with surgery for AIS report better preoperative self-image, less postoperative pain, and better mental health than females. These differences may be clinically significant. For both males and females, the most beneficial effect of surgery is improved self-image/appearance. Overall, the benefits of surgery for AIS are similar for both sexes.

The purpose of this study was to compare differences in health-related quality of life (HRQOL) between African-American female breast cancer survivors, African-American female survivors of other cancers, and African-American women with no history of cancer. Using data from the 2010 National Health Interview Survey (NHIS), the HRQOL of African-American women aged 35 years or older was compared by cancer status. Physical and mental health items from the Patient-Reported Outcomes Measurement Information System (PROMIS) global health scale were used to assess differences in HRQOL. For summary physical and mental health measures, no significant differences were found between breast cancer survivors and women with no history of cancer; survivors of other cancers reported poorer physical and mental health than did women with no history of cancer. Similar differences were found at the item level. When we examined the two African-American female cancer survivor groups, we found that cancer survivors whose cancer was being treated reported substantially poorer physical health and mental health than did those whose cancer was not being treated. Survivors who had private insurance and were cancer free reported better physical and mental health than did those who did not have private insurance and those who were not cancer free. Breast cancer survivors reported slightly better physical and mental health than did survivors of other cancers. Our findings highlight the need for public health agencies to adopt practices to improve the mental and physical health of African-American female survivors of cancer.

This study was carried out on 468 cases among total 4347 cancer cases which was confirmly diagnosed as malignant neoplasms at Yonsei Center Hospital, appended to Yonsei University, during 10 years from January 1, 1971 to December 31, 1980. The results of this study are as follows: 1. Total malignant neoplasm cases treated with radiation were 4347, 1685 of whom were males, and 2662 females (male to female ratio was 1:1.58). 2. Lung cancer were 10.8% of total malignant neoplasm cases(468 cases), 391 cases for the male and 77 cases for the female. So, average the male to female ratio was 8:1 and cases of the male were much more. 3. The age distribution of lung cancer cases was from 27 to 82 years old. The highest age distribution was 50-59 for males (37.9%) and 60-69 for females (41.6%); 77.1% of total lung cancer cases were over 50 years old. 4. In regard to stages, the distribution of the third stage was highest (49.3%). That of the first stage was much higher during the last period (11.8%) than the first period (2.7%), and that of the fourth stage was much lower during the last period (7.8%) than the first period (21.1%). 5. In regard to pathological type, the distribution was 51.3% for squamous cell carcinoma, 29.3% for undifferentiated cell carcinoma, 12.2% for adenocarcinoma, and 7.2% for bronchoalveolar cell carcinoma in order of frequency. In regard to adenocarcinoma, the male ratio was 1:3.7 and cases of the female were much more. 6. In regard to tumor location,the distribution of tumor location in the right-left lobe was 59.1% in the right lobe, 33.6% in the left lobe, and 7.3% in the both lobes in order of frequency. And that of tumor location in the upper and lower lobes was all higher in the upper in the upper lobe; especially, that of the right upper lobe was highest (31.2% of total cases). 7. For the main symptom, coughing was highest (64%), 50% for hemoptysis, and 41% for dyspnea. (Author)

Adult Gli2+/-;Gli3Δ699/+ Male and Female Mice Display a Spectrum of Genital Malformation.

Directory of Open Access Journals (Sweden)

Fei He

Full Text Available Disorders of sexual development (DSD encompass a broad spectrum of urogenital malformations and are amongst the most common congenital birth defects. Although key genetic factors such as the hedgehog (Hh family have been identified, a unifying postnatally viable model displaying the spectrum of male and female urogenital malformations has not yet been reported. Since human cases are diagnosed and treated at various stages postnatally, equivalent mouse models enabling analysis at similar stages are of significant interest. Additionally, all non-Hh based genetic models investigating DSD display normal females, leaving female urogenital development largely unknown. Here, we generated compound mutant mice, Gli2+/-;Gli3Δ699/+, which exhibit a spectrum of urogenital malformations in both males and females upon birth, and also carried them well into adulthood. Analysis of embryonic day (E18.5 and adult mice revealed shortened anogenital distance (AGD, open ventral urethral groove, incomplete fusion of scrotal sac, abnormal penile size and structure, and incomplete testicular descent with hypoplasia in male mice, whereas female mutant mice displayed reduced AGD, urinary incontinence, and a number of uterine anomalies such as vaginal duplication. Male and female fertility was also investigated via breeding cages, and it was identified that male mice were infertile while females were unable to deliver despite becoming impregnated. We propose that Gli2+/-;Gli3Δ699/+ mice can serve as a genetic mouse model for common DSD such as cryptorchidism, hypospadias, and incomplete fusion of the scrotal sac in males, and a spectrum of uterine and vaginal abnormalities along with urinary incontinence in females, which could prove essential in revealing new insights into their equivalent diseases in humans.

Female genital mutilation.

Ladjali, M; Rattray, T W; Walder, R J

Female genital mutilation, also misleadingly known as female circumcision, is usually performed on girls ranging in from 1 week to puberty. Immediate physical complications include severe pain, shock, infection, bleeding, acute urinary infection, tetanus, and death. Longterm problems include chronic pain, difficulties with micturition and menstruation, pelvic infection leading to infertility, and prolonged and obstructed labor during childbirth. An estimated 80 million girls and women have undergone female genital mutilation. In Britain alone an estimated 10,000 girls are currently at risk. Religious, cultural, medical, and moral grounds rationalize the custom which is practiced primarily in sub-Saharan Africa, the Arab world, Malaysia, Indonesia, and among migrant populations in Western countries. According to WHO it is correlated with poverty, illiteracy, and the low status of women. Women who escape mutilation are not sought in marriage. WHO, the UN Population Fund, the UN Children's Fund, the International Planned Parenthood Federation, and the UN Convention on the Rights of the Child have issued declarations on the eradication of female genital mutilation. In Britain, local authorities have intervened to prevent parents from mutilating their daughters. In 1984, the Inter-African Committee Against Harmful Traditional Practices Affecting Women and Children was established to work toward eliminating female genital mutilation and other damaging customs. National committees in 26 African countries coordinate projects run by local people using theater, dance, music, and storytelling for communication. In Australia, Canada, Europe, and the US women have organized to prevent the practice among vulnerable migrants and refugees.

The article consists of six sections written by separate authors that review female genital anatomy, the physiology of female sexual function, and the pathophysiology of female sexual dysfunction but excluding hormonal aspects. To review the physiology of female sexual function and the pathophysiology of female sexual dysfunction especially since 2010 and to make specific recommendations according to the Oxford Centre for evidence based medicine (2009) "levels of evidence" wherever relevant. Recommendations were made for particular studies to be undertaken especially in controversial aspects in all six sections of the reviewed topics. Despite numerous laboratory assessments of female sexual function, genital assessments alone appear insufficient to characterise fully the complete sexual response.

Assessing the feeling of loneliness of women treated because of infertility compared to women without any procreation problems, and verifying, whether there is a correlation with the presented personality traits. 26 women treated for infertility (in accordance with the officially recognized criteria) in the Obstetrics and Women Health Clinic at the Medical University in Gdańsk, and 25 women not experiencing any procreation problems, were included into the study The research tools included a self-constructed sociodemographic questionnaire, the Minnesota Multiphasic Personality Inventory (MMPI) and the UCLA Loneliness Scale by D. Russell, L. Peplau, C. Cytron. There are significant differences among the investigated groups in terms of the following personality dimensions: Masculinity - Femininity Paranoia, Psychasthenia, Schizophrenia and the Social Introversion Scale. Women treated because of infertility scored higher in all these scales, their results remained within the norm though. The studied groups demonstrated different relations between the MMPI scales and the UCLA scales results. Women treated due to infertility have a personality profile similar to women without any procreation problems. Only the group whose profiles exhibited some pathological features demonstrated symptoms of worse adaptation to life, a tendency to experience a higher psychological discomfort and higher psychological stress, higher level of anxiety related to being assessed by others, and greater difficulties in accepting the role of a female. As far as the sense of loneliness was concerned women treated due to infertility did not differ significantly from the ones without procreation problems.

Emerging technologies for food preservation have arisen in recent years, such as high-pressure (HP) hydrostatic treatment, and the biological response for this kind of food preservation is not well-known. Forty female rats (six weeks old) were used in the experiment to evaluate the biological effects of HP treatment of tofu. The animals were divided into groups that were fed with tofu (untreated), tofu treated with HP, and conventional food (as control) for 28 days. The glucose level, mineral content (calcium, potassium, zinc, and magnesium), shinbone maximum shear force, weight of the body, and weight of organs (heart, liver, spleen, and kidneys) were analyzed. The biological response for the rats was that significant differences were found in the calcium amount determined on the serum of the rats fed with untreated tofu and those fed with tofu treated with HP, and the calcium amount was lower on the rats fed with tofu treated with HP. Also, there were significant differences in the weight of the liver, and it was lower in the rats fed with tofu treated with HP. It was quite remarkable how the weight of the body and organs were smaller in the rats fed with tofu in comparison to the weight of the control rats. In the other components assayed no significant differences were found. HP produces a potential effect on tofu as it is observed in the rats response to the tofu treated with HP.

We aim to investigate the reasons that medical students and junior doctors who are women are less likely to pursue a career in surgery compared with their male counterparts. An anonymous questionnaire was distributed to female final year medical students and female junior doctors in two UK hospitals between August and September 2012. Topics included career choice, attitudes to surgery, recognition of female surgical role models and perceived sexual discrimination. 50 medical students and 50 junior doctors were given our survey. We received a 96% response rate; 46 medical students and 50 junior doctors. 6/50 (12%) junior doctors planned a career in surgery compared with 14/46 (30%) medical students. 'Work-life balance' was the main reason cited for not wishing to pursue surgery (29/46 (63%) medical students and 25/50 (50%) junior doctors). 28/46 (61%) medical students and 28/50 (56%) junior doctors had encountered a female surgical role model; only five students and two junior doctors felt that these were influential in their career decision. Of those who had not, approximately 40% in each group felt that if they had, they may have considered surgery. Approximately 30% in each group had encountered female surgeons that had dissuaded them from a surgical career. Work-life balance is still cited by female junior doctors as being the main deterrent to a surgical career. The paucity of female role models and some perceived sexual discrimination may cause female doctors to discount surgery as a career. Published by the BMJ Publishing Group Limited.

The underrepresentation of women in physics doctorate programs and in tenured academic positions indicates a need to evaluate what may influence their career choice and persistence. This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and long-term support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women’s support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and long-term support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women’s support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

Tension Type Headache (T.T.H) is the most prevalent headache. Myofascial abnormalities & trigger points are important in this type of headache which can be managed by Positional Release Therapy (PRT). This is a report of a 47 years old female patient with Tension Type Headache treated by Positional Release Therapy for her trigger points. She had a constant dull headache, which continued all the day for 9 months. A physiotherapist evaluated the patient and found active trigger points in her cervical muscles. Then, she received Positional Release Therapy for her trigger points. After 3 treatment sessions, the patient's headache stopped completely. During the 8 months following the treatment she was without pain, and did not use any medication. Positional Release Therapy was effective in treating Tension Type Headache. This suggests that PRT could be an alternative treatment to medication in patients with T.T.H if the effectiveness of that can be confirmed by further studies. Copyright © 2012 Elsevier Ltd.

Female urinary incontinence and sexuality

Directory of Open Access Journals (Sweden)

Renato Lains Mota

Full Text Available ABSTRACT Urinary incontinence is a common problem among women and it is estimated that between 15 and 55% of them complain of lower urinary symptoms. The most prevalent form of urinary incontinence is associated with stress, followed by mixed urinary incontinence and urge urinary incontinence. It is a symptom with several effects on quality of life of women mainly in their social, familiar and sexual domains. Female reproductive and urinary systems share anatomical structures, which promotes that urinary problems interfere with sexual function in females. This article is a review of both the concepts of female urinary incontinence and its impact on global and sexual quality of life. Nowadays, it is assumed that urinary incontinence, especially urge urinary incontinence, promotes anxiety and several self-esteem damages in women. The odour and the fear of incontinence during sexual intercourse affect female sexual function and this is related with the unpredictability and the chronicity of incontinence, namely urge urinary incontinence. Female urinary incontinence management involves conservative (pelvic floor muscle training, surgical and pharmacological treatment. Both conservative and surgical treatments have been studied about its benefit in urinary incontinence and also the impact among female sexual function. Unfortunately, there are sparse articles that evaluate the benefits of female sexual function with drug management of incontinence.

Female-biased dimorphism underlies a female-specific role for post-embryonic Ilp7 neurons in Drosophila fertility

Castellanos, Monica C.; Tang, Jonathan C. Y.; Allan, Douglas W.

2013-01-01

In Drosophila melanogaster, much of our understanding of sexually dimorphic neuronal development and function comes from the study of male behavior, leaving female behavior less well understood. Here, we identify a post-embryonic population of Insulin-like peptide 7 (Ilp7)-expressing neurons in the posterior ventral nerve cord that innervate the reproductive tracts and exhibit a female bias in their function. They form two distinct dorsal and ventral subsets in females, but only a single dorsal subset in males, signifying a rare example of a female-specific neuronal subset. Female post-embryonic Ilp7 neurons are glutamatergic motoneurons innervating the oviduct and are required for female fertility. In males, they are serotonergic/glutamatergic neuromodulatory neurons innervating the seminal vesicle but are not required for male fertility. In both sexes, these neurons express the sex-differentially spliced fruitless-P1 transcript but not doublesex. The male fruitless-P1 isoform (fruM) was necessary and sufficient for serotonin expression in the shared dorsal Ilp7 subset, but although it was necessary for eliminating female-specific Ilp7 neurons in males, it was not sufficient for their elimination in females. By contrast, sex-specific RNA-splicing by female-specific transformer is necessary for female-type Ilp7 neurons in females and is sufficient for their induction in males. Thus, the emergence of female-biased post-embryonic Ilp7 neurons is mediated in a subset-specific manner by a tra- and fru-dependent mechanism in the shared dorsal subset, and a tra-dependent, fru-independent mechanism in the female-specific subset. These studies provide an important counterpoint to studies of the development and function of male-biased neuronal dimorphism in Drosophila. PMID:23981656

Full Text Available Background: Sexual violence in South Africa is a major public health and social problem. Sexual assault or rape is a traumatic event which disrupts not only the life of the female rape victim, but also that of her male intimate partner (MIP, irrespective of whether he witnessed or was informed of the incident.Objectives: The study aimed to explore the lived experiences of MIPs of female rape victims and the meaning of these experiences in the six months following the partner’s rape.Method: We conducted a longitudinal hermeneutic phenomenological study. Nine purposively sampled adult MIPs were interviewed over a period of six months. The participants were in an intimate relationship with a female rape victim prior to and immediately after the rape; their partners had been treated at a specialised centre for victims of rape and sexual assault. Four interviews were conducted with each of the nine intimate partners of female rape victims: (1 within 14 days of, (2 a month after, (3 three months after, and (4 six months after the rape.Results: Two major themes emerged: being-in-the-world as a secondary victim of rape, and living in multiple worlds, those of their female partners, family, friends, society, employers or colleagues, professionals and the justice system. The participant’s familiar world became strange and even threatening, and his relationship with his partner became uncertain.Conclusion: Early supportive intervention for intimate partners of female rape victims is required to prevent on-going emotional trauma and alleviate the effects of chronic post-traumatic stress disorder and suffering at intra- and interpersonal levels.

Decreased duration of pentobarbital-induced narcosis in immature and adult female rats prenatally exposed to cimetidine

The effect of prenatal cimetidine exposure (PreCM) on the duration of pentobarbital-induced narcosis (DPN) was assessed in immature (14- and 28-day old) and adult (50-60-day old) male and female rats. PreCM exposure was accomplished by treating mothers with cimetidine (CM) (20 mg/kg, ip) daily for the last two days of gestation and then (0.01% in drinking water) throughout lactation. Pregnant mothers of untreated offspring (Con) received saline. PreCM decreased DPN to 505 +/- 33 min (from 611 +/- 23 min in Con) and 393 +/- 190 min (from 686 +/- 44 min in Con) in 14-day old male and female rats, respectively. Similarly, PreCM decreased DPN to 88 +/- 15 min (from 134 +/- 3 min in Con) and 102 +/- 19 min (from 171 +/- 44 min in Con) in 28-day old male and female rats, respectively. At 21 days, PreCM did not alter DPN in either sex. At 50-60 days, however, it decreased DPN to 144 +/- 41 min (from 238 +/- 7 min in Con) in females but had no effect in males; PreCM also increased the plasma clearance of administered 14 C-pentobarbital more in females than in males. The effects of PreCM, particularly the long-term effects, were most prominent in female rats and were the opposite of those of postnatal treatment with CM. The results together with those of studies with hepatic microsomes suggest that PreCM may have resulted in the induction of hepatic drug-metabolizing enzymes during the perinatal period

The study aimed to determine if the addition of daily low-dose oral estrogen with a cyclical progestogen given to young women using a depot gonadotropin-releasing hormone (GnRH) analog implant for the treatment of their premenstrual syndrome (PMS) would affect the clinical outcome. In a double-blind placebo-controlled study in a specialist premenstrual syndrome clinic setting, 60 women aged between 20 and 45 years were randomized to one of three treatment groups: Group A (placebo implant four weekly + placebo tablets daily), Group B (goserelin 3.6 mg implant four weekly + estradiol valerate 2 mg daily with norethisterone 5 mg from days 21-28 of a 28-day cycle) or Group C (goserelin 3.6 mg implant four weekly + placebo tablets daily). Differences between PMS scores at 2, 4 and 6 months were compared with pretreatment values. There was a significant improvement in PMS scores in Group C (Zoladex + placebo) after 2, 4 and 6 months of treatment when compared to pretreatment values and Group A (placebo + placebo). The addition of a low-dose oral estrogen with a cyclical progestogen to GnRH analog treatment (Group B) resulted in a less dramatic response when compared to pretreatment values and no significant improvement when compared to Group A (placebo + placebo) at 2, 4 and 6 months of treatment. The addition of a low-dose oral estrogen with a cyclical progestogen to depot GnRH analog therapy in the treatment of PMS reduces the clinical response.

Estrogen and progestogen use in postmenopausal women: July 2008 position statement of The North American Menopause Society

Science.gov (United States)

2009-01-01

Objective To update for both clinicians and the lay public the evidence-based position statement published by The North American Menopause Society (NAMS) in March 2007 regarding its recommendations for menopausal hormone therapy (HT) for postmenopausal women, with consideration for the therapeutic benefit-risk ratio at various times through menopause and beyond. Design An Advisory Panel of clinicians and researchers expert in the field of women’s health was enlisted to review the March 2007 NAMS position statement, evaluate new evidence through an evidence-based analysis, and reach consensus on recommendations. The Panel’s recommendations were reviewed and approved by the NAMS Board of Trustees as an official NAMS position statement. The document was provided to other interested organizations to seek their endorsement. Results Current evidence supports a consensus regarding the role of HT in postmenopausal women, when potential therapeutic benefits and risks around the time of menopause are considered. This paper lists all these areas along with explanatory comments. Conclusions that vary from the 2007 position statement are highlighted. Addenda include a discussion of risk concepts, a new component not included in the 2007 paper, and a recommended list of areas for future HT research. A suggested reading list of key references is also provided. Conclusions Recent data support the initiation of HT around the time of menopause to treat menopause-related symptoms; to treat or reduce the risk of certain disorders, such as osteoporosis or fractures in select postmenopausal women; or both. The benefit-risk ratio for menopausal HT is favorable close to menopause but decreases with aging and with time since menopause in previously untreated women. PMID:18580541

Adult survivors of childhood cancers are more prone to developing poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation during childhood. Chemotherapy drugs exert cytotoxic effects systemically and therefore can damage the ovaries, leading to infertility, premature ovarian failure, and, to a lesser extent, spontaneous abortions. They have very limited or no deleterious effects on the uterus that can be recognized clinically. By contrast, radiation is detrimental to both the ovaries and the uterus, thereby causing a greater magnitude of adverse effects on the female reproductive function. These include infertility, premature ovarian failure, miscarriage, fetal growth restrictions, perinatal deaths, preterm births, delivery of small-for-gestational-age infants, preeclampsia, and abnormal placentation. Regrettably, the majority of these adverse outcomes arise from radiation-induced uterine injury and are reported at higher incidence in the adult survivors of childhood cancers who were exposed to uterine radiation during childhood in the form of pelvic, spinal, or total-body irradiation. Recent findings of long-term follow-up studies evaluating reproductive performance of female survivors provided some reassurance to female cancer survivors by documenting that pregnancy and live birth rates were not significantly compromised in survivors, including those who had been treated with alkylating agents and had not received pelvic, cranial, and total-body irradiation. We aimed in this narrative review article to provide an update on the impact of chemotherapy and radiation on the ovarian and uterine function in female survivors of childhood cancer. Adult survivors of childhood cancers are more prone to developing a number of poor reproductive and obstetrical outcomes than their siblings and the general population as a result of previous exposure to chemotherapy and radiation

Several evidences indicate that the locus coeruleus (LC) is involved in central chemoreception responding to CO 2 /pH and displaying a high percentage of chemosensitive neurons (>80%). However, there are no studies about the LC-mediated hypercapnic ventilation performed in females. Therefore, we assessed the role of noradrenergic LC neurons in non-ovariectomized (NOVX), ovariectomized (OVX) and estradiol (E2)-treated ovariectomized (OVX+E2) rats in respiratory response to hypercapnia, using a 6-hydroxydopamine (6-OHDA) - lesion model. A reduction in the number of tyrosine hydroxylase (TH) immunoreactive neurons (51-90% in 3 animals of NOVX group, 20-42% of lesion in 5 animals of NOVX females, 61.3% for OVX and 62.6% for OVX+E2 group) was observed seven days after microinjection of 6-OHDA in the LC. The chemical lesion of the LC resulted in decreased respiratory frequency under normocapnic conditions in OVX and OVX+E2 group. Hypercapnia increased ventilation in all groups as consequence of increases in respiratory frequency (fR) and tidal volume (V T ). Nevertheless, the hypercapnic ventilatory response was significantly decreased in 6-OHDA-NOVX>50% rats compared with SHAM-NOVX group and with females that had 20-42% of LC lesion. In OVX and OVX+E2 lesioned groups, no difference in CO 2 ventilatory response was observed when compared to SHAM-OVX and SHAM-OVX+E2 groups, respectively. Neither basal body temperature (Tb) nor Tb reduction in response to hypercapnia were affected by E2 treatment, ovariectomy or LC lesion. Thus, our data show that LC noradrenergic neurons seem to exert an excitatory role on the hypercapnic ventilatory response in female rats, as evidenced by the results in NOVX animals with LC lesioned more than 50%; however, this modulation is not observed in OVX and OVX+E2 rats. In addition, LC noradrenergic neurons of OVX females seem to provide a tonic excitatory drive to maintain breathing frequency in normocapnia, and this response may not to be

Women in perfusion: a survey of North American female perfusionists.

Perfusion as a career has long been dominated by men (American Board of Cardiovascular Perfusion, Booklet of information since 1975). Women represent 33.3% of the present workforce in North America (1187 certified women). In the 1900s, fewer than 20% of women participated in the labor force compared with 75% today and growing (1). In addition women make only 77 cents for every dollar that men earn and the more education a woman has, the greater the disparity in her wages (2). Only 53% of employers provide at least some replacement pay during periods of maternity leave (2). The purpose of this survey was to poll women in perfusion to evaluate concerns and opinions in their careers and to compare this with the female labor force. In October 2011, a 40-question survey (surveymonkey.com) was made available to all female perfusionists in North American by postcard mailing through the American Board of Cardiovascular Perfusion. There were 538 responses to the survey, which is 45% of all female certified perfusionists in North America. A total of 32.6% of the survey participants have been in perfusion for more than 20 years and 75% are staff perfusionists, working for a hospital (59.5%) rather than a contract group (36.7%). A total of 44.7% of women who had children during their employment were out on leave 10 weeks or less. A total of 95.9% feel they miss important family functions as a result of their work schedules and 63% consider themselves under moderate stress. Direct supervision of the participants by men occurred in 76.5% of cases, and 68.2% felt that they were treated with the same respect as male coworkers. Nonetheless, 50.9% felt discriminated against because of gender. This survey suggests that the female perfusionists in North America share the same difficulties as women in the labor force. The role of women in society in general is clearly changing. Female perfusionists will be part of that change. Seventy percent of those surveyed would recommend perfusion

DOES GENDER IMPACT ON FEMALE DOCTORS' EXPERIENCES IN THE TRAINING AND PRACTICE OF SURGERY?

Surgery has been a male-dominated speciality both in South Africa and abroad. This mixed methodology case study collected data from a purposive sample of female surgical registrars enrolled at one institution in South Africa. A self-administered questionnaire was used to explore whether or not female doctors perceived any benefits of being in a male-dominated specialty. It explored problems encountered due to gender, the participants' perceptions of the influence of gender on their surgical training, practice and challenges. Thirty-two female registrars participated in the study. The respondents were mainly South African (91%) and enrolled in seven surgical specialities. Twenty-seven (84%) respondents were satisfied with their practical training and skills development as surgeons. Twenty-four (75%) respondents had identified a mentor from the department and all respondents indicated that the gender of their mentor did not impact on the quality of their training. Seventeen (53%) respondents perceived having received differential treatment due to their gender and 25 (78.2%) thought that the gender of their mentor did not impact on the quality of the guidance in surgery. Challenges included physical threats to them as females from patients and disrespect, emotional threats and defaming statements from male registrars. Other challenges included time-constraints for family and academic work, poor work life balance and being treated differently due to their gender. Seventeen (53%) respondents would consider teaching in the Department of Surgery. Twenty-five respondents (78%) would recommended the specialty to young female students, as they were convinced that surgery had been the right choice for them. Seventeen respondents (53%) were also open to pursuing teaching posts in the Department of Surgery. Generally, females had positive perceptions of their training in Surgery. They expressed concern about finding a worklife balance. The gender of their mentor did not impact

Female behaviour and the interaction of male and female genital traits mediate sperm transfer during mating.

Friesen, C R; Uhrig, E J; Mason, R T; Brennan, P L R

Natural selection and post-copulatory sexual selection, including sexual conflict, contribute to genital diversification. Fundamental first steps in understanding how these processes shape the evolution of specific genital traits are to determine their function experimentally and to understand the interactions between female and male genitalia during copulation. Our experimental manipulations of male and female genitalia in red-sided garter snakes (Thamnophis sirtalis parietalis) reveal that copulation duration and copulatory plug deposition, as well as total and oviductal/vaginal sperm counts, are influenced by the interaction between male and female genital traits and female behaviour during copulation. By mating females with anesthetized cloacae to males with spine-ablated hemipenes using a fully factorial design, we identified significant female-male copulatory trait interactions and found that females prevent sperm from entering their oviducts by contracting their vaginal pouch. Furthermore, these muscular contractions limit copulatory plug size, whereas the basal spine of the male hemipene aids in sperm and plug transfer. Our results are consistent with a role of sexual conflict in mating interactions and highlight the evolutionary importance of female resistance to reproductive outcomes. © 2016 European Society For Evolutionary Biology.

Neonatal exposure to genistein (GEN), an isoflavone abundant in soy, favorably modulates bone mineral density (BMD) and bone strength in mice at adulthood. The study objective was to determine whether early exposure to a combination of the soy isoflavones daidzein (DAI) and GEN that naturally exists in soy protein-based infant formula results in greater benefits to bone at adulthood than either treatment alone. Male and female CD-1 mice (n = 8-16 pups per group per gender) were randomized to subcutaneous injections of DAI (2 mg x kg body weight(-1) x d(-1)), GEN (5 mg x kg body weight(-1) x d(-1)), DAI+GEN (7 mg x kg body weight(-1) x d(-1)), diethylstilbesterol (DES; positive control) (2 mg x kg body weight(-1) x d(-1)), or control (CON) from postnatal d 1-5 and were studied to 4 mo of age. BMD, biomechanical bone strength, and bone microarchitecture were assessed at the femur and lumbar vertebrae (LV). Females treated with DAI, GEN, DAI+GEN, or DES had greater (P GEN resulted in greater (P GEN had a positive effect on the skeleton of female mice at adulthood, but, compared with individual treatments, DAI+GEN did not have a greater benefit to bone in females or males.

To study the outcome of Radioactive Iodine (RAI) in treatment of hyperthyroidism. It is a retrospective study of all patients of hyperthyroidism treated by Radioactive Iodine (RAI) seen in endocrinology clinic at King Abdulaziz University Hospital and Dr. Soliman Fageeh Hospital in Jeddah, Saudia Arabia. Two hundred and sixteen (216) patients were treated by RAI. They proved to have hyperthyroidism by thyroid function test (TSH, FT4 and T3) and isotopes scanning of the thyroid gland. All received 10 mci of RAI and were then followed up after one month and every two months thereafter for at least one year. The efficacy of the therapy was assessed by the improvement of the clinical features and by the thyroid function tests. A total of 216 patients were seen, the mean age was 36.5+- 10.64 years. One hundred fifty three were female and sixty three were male. Graves disease was the underlying cause in 163 patients [65.55%], toxic multi nodular goiter in 37 patients [25.1%] and toxic adenoma in 16 patients [9.3%]. The symptoms improved after one month only in 11 patients but others required antithyroid treatment for two months. Only 17 patients remained hyperthyroid after six months of treatment. Radioactive iodine is very effective in treatment of hyperthyroidism with minor side effects such as weight gain, fatigability and hypothyroidism. (author)

To observe the clinical effect of post-extension pulling massage in treating lumbar disc herniation. From January 2008 to December 2008, 61 patients with lumbar disc herniation, 34 males and 27 females, ranging in age from 17 to 67 years with an average of 42.6 years, were treated with post-extension pulling massage after continued traction for 30 minutes (on alternate days one time, 3 times as a course of treatment). There was bulging type in 9 cases, hernia type in 22, free type in 30. After a course of treatment, the clinical effects were evaluated according to standard of Macnab, the items included pain, lumbar activity, normal work and life of patients. All patients were followed up from 1 to 9 months with an average of 4.6 months. After treatment, the symptoms and signs of patients had obviously improved in above aspects. According to standard of Macnab, 48 cases got excellent result, 10 good, 2 fair, 1 poor. The post-extension pulling massage in treating lumbar disc herniation can obtain satisfactory results, which have localized site of action, small compression for vertebral body and can reduce accidental injury.

Laboratory studies were conducted to evaluate the effects of treating military canvas tent fabric with bifenthrin and permethrin on the survival of the eggs and larvae of Aedes aegypti. Gravid female Ae. aegypti were able to oviposit on tent canvas treated with either bifenthrin or permethrin. However, none of the eggs laid on treated canvas hatched, and no larvae added to water in treated trays survived. Low residual concentrations of bifenthrin and permethrin on treated canvas prevented the development of eggs and larvae of Ae. aegypti. Inhibition of bloodfeeding was shown when Ae. aegypti adults were exposed to lower concentrations (10-50% of operational concentrations) of bifenthrin- and permethrin-treated canvas tent fabric. These experiments have shown that military tent canvas treated with either bifenthrin or permethrin can reduce the development of Ae. aegypti eggs and larvae and reduce bloodfeeding success of adults.

Arcuate neurons that coexpress kisspeptin (Kiss1), neurokinin B (Tac2), and dynorphin (Pdyn) mediate negative feedback of 17β-estradiol (E2) on the HPG axis. Previous studies report that fasting and caloric restriction reduce arcuate Kiss1 expression. The objective of this study was to determine the interactions of E2 with fasting, caloric restriction, and diet-induced obesity on KNDy gene and receptor expression. Ovariectomized female mice were separated into control and estradiol benzoate (E2B)-treated groups. E2B decreased Kiss1 and the tachykinin 2 receptor, Tac3r, in ARC tissue and Tac2 in Tac2 neurons. Diet-induced obesity decreased Kiss1 in oil-treated animals and the kisspeptin receptor, Kiss1r and Tac3r in the ARC of E2B-treated animals. Chronic caloric (30%) restriction reduced all three neuropeptides in oil-treated females and Kiss1r by E2B in CR animals. Taken together, our experiments suggest that steroidal environment and energy state negatively regulate KNDy gene expression in both ARC and Tac2 neurons. Copyright © 2016 Elsevier Ireland Ltd.

Purpose We compared outcomes of the U- and H-type approaches of the tension-free vaginal tape (TVT)-Secur procedure for the treatment of female stress urinary incontinence (SUI). Materials and Methods From March 2007 to July 2008, 115 women with SUI underwent TVT-Secur by a single surgeon. Patients were randomly assigned to either the U- or the H-type approach. After 12 months, postoperative changes in the Sandvik questionnaire, incontinence quality of life questionnaire (I-QoL), Bristol female lower urinary tract symptoms-scored form (BFLUTS-SF), and postoperative patient satisfaction were evaluated. Cure was regarded as no leakage on the Sandvik questionnaire. Complications were also evaluated. Results Of 115 women, 53 were treated with the U approach, and 62 women were treated with the H approach. At 12 months, 88.7% of those treated with the U approach and 87.1% of those treated with the H approach were cured (p=0.796). The I-QoL and filling, incontinence, sexual function, and QoL sum (BFLUTS-SF) scores were improved with both approaches, and there were no significant differences in the degree of improvement between approaches. Approximately 83.7% and 82.9% of the women treated with the U and H approaches, respectively, were satisfied with the outcome (p=0.858). There were 3 cases of intra-operative vaginal wall perforation in the H-type group. Immediate postoperative retention was observed in 2 women in the U-type group and 1 woman in the H-type group. One woman in the U-type group underwent tape releasing and cutting procedures for persistent large post-void residuals. Conclusions The U- and the H-type approaches of the TVT-Secur procedure provided comparable effectiveness for the treatment of female SUI. PMID:20428427

Gamma irradiation (6 krad 2 days before eclosion or 8 krad 2 days after eclosion) induced 98-99% sterility in a laboratory strain of male Dacus cucurbitae Coquillett. Comparable females with 4 krad at the same ages were completely infecund. In trials with 5:1:1 ratios of sterile males-normal males-normal females, sexual competitiveness of males sterilized with 8 krad as 2-day-old adults was similar to that of males treated as pupae with 6 krad. The suppression of the fertility of normal flies by the introduction of sterile females was negligible

Human's ubiquitous exposure to di (2-ethylhexyl) phthalate (DEHP) is thought to be associated with female reproductive toxicity. Previous studies found that DEHP inhibited follicle growth and decreased estradiol levels in adult female mice. However, limited information is available on the link between in utero DEHP exposure and ovarian development in female mouse offspring. The present study evaluates the disturbances in regulatory genes involved in female sex determination and the ovarian outcomes in fetal and postnatal female mice treated with in utero DEHP exposure. Pregnant mice were exposed to DEHP by gavage, with the dosage regime beginning at human relevant exposure levels. After in utero DEHP exposure, increased follicular atresia was observed in the female pups at postnatal days (PND) 21. Foxl2 expression was significantly upregulated, and Fst was significantly downregulated by DEHP above 2 mg/kg/d at PND 1 and 21. This suggests that lesion of granulosa cell differentiation and disturbance of follicle development in postnatal female mice. The expression of Cyp11a1 and Star were significantly downregulated by in utero DEHP exposure, indicating effects on estradiol biosynthesis. The female sex determination pathway was disturbed in fetus by DEHP at 2 mg/kg/d and above during the critical time window of sex determination causing significant upregulation of Foxl2, Wnt4, β-catenin and Fst. Furthermore, the increased expression of Wnt4 was supported by whole-mount in situ hybridization (WISH). These results suggest a possible association between in utero DEHP exposure and precocious puberty in the postnatal life of mice offspring, where disturbance of the sex determination regulating pathway acted as an important mechanism. - Highlights: • Maternal exposure to di (2-ethylhexyl) phthalate disturbs fetus sex determination. • DEHP upregulated Foxl2 expression potentially disturbs postnatal granulosa cell differentiation. • DEHP accelerated medulla

The current study was performed to evaluate the toxicity of Cuminum cyminum L. (C. cyminum)'s essential oil after 23 days and 45 days of repeated oral administration in female Wistar rats. A total of 80 healthy female Wistar rats were randomly selected and divided into 4 groups. The rats were gavaged with C. cyminum's essential oil at dose levels of 0, 250, 500 and 1000 mg/kg/day. Clinical signs, body weight, hematology, serum biochemistry and organ histopathology were assessed once after 23 days and again after 45 days passed from the start of the intervention. Oral administration of C. cyminum's essential oil had no observed adverse effects on clinical signs, mortality, body weight, hematology, biochemistry and organ histology (liver, kidneys, spleen and lungs) in a sample of healthy female Wistar rats after 23 days and 45 days from the start of the study. However, an increase in serum levels of alanine transaminase (ALT) was found only at dose level of 1000 mg/kg/d C. cyminum's essential oil, after the 23-days interval. We conservatively defined the non-observed adverse effect level (NOAEL) for C. cyminum's essential oil as 500 mg/kg/d in female Wistar rats. The present study results should be treated with cautious in terms of the other organs' toxicity. Copyright © 2017 Elsevier Inc. All rights reserved.

The objective of this research was to evaluate the interference of ethanol consumption by female rats with cytokines involved in the sepsis process and its correlation with mortality, the main outcome of sepsis. Female Wistar rats in estrus phase were evaluated in three experiments. Experiment 1 (n=40) was performed to determine survival rates. Experiment 2 (n=69) was designed for biochemical analysis, measurement of cytokine and estrogen levels before and after sepsis, and experiment 3 (n=10) was performed to evaluate bacterial growth by colony counts of peritoneal fluid. In all experiments, treated animals were exposed to a 10% ethanol/water solution (v/v) as the single drinking source, while untreated animals were given tap water. After 4 weeks, sepsis was induced in the rats by ip injection of feces. In experiment 1, mortality in ethanol-exposed animals was delayed compared with those that drank water (48 h; P=0.0001). Experiment 2 showed increased tumor necrosis factor alpha (TNF-α) and decreased interleukin-6 (IL-6) and macrophage migration inhibitory factor in septic animals exposed to ethanol compared to septic animals not exposed. Sepsis also increased TNF-α and IL-6 levels in both ethanol- and water-exposed groups. Biochemical analysis showed higher creatinine, alanine aminotransferase and aspartate aminotransferase and decreased glucose levels in septic animals that were exposed to ethanol. In experiment 3, septic animals exposed to ethanol showed decreased numbers of colony-forming units than septic animals exposed to water. These results suggest that ethanol consumption delays the mortality of female rats in estrus phase after sepsis induction. Female characteristics, most probably sex hormones, may be involved in cytokine expression.

Weckerly, Floyd W.; Ricca, Mark A.

Female caribou (Rangifer tarandus) are highly gregarious, yet there has been little study of the behavioral mechanisms that foster coexistence. Quantifying patterns of aggression between male and female, particularly in the only cervid taxa where both sexes grow antlers, should provide insight into these mechanisms. We asked if patterns of aggression by male and female caribou followed the pattern typically noted in other polygynous cervids, in which males display higher frequencies and intensity of aggression. From June to August in 2011 and 2012, we measured the frequency and intensity of aggression across a range of group sizes through focal animal sampling of 170 caribou (64 males and 106 females) on Adak Island in the Aleutian Archipelago, Alaska. Males in same-sex and mixed-sex groups and females in mixed-sex groups had higher frequencies of aggression than females in same-sex groups. Group size did not influence frequency of aggression. Males displayed more intense aggression than females. Frequent aggression in mixed-sex groups probably reflects lower tolerance of males for animals in close proximity. Female caribou were less aggressive and more gregarious than males, as in other polygynous cervid species.

The female athlete triad.

Science.gov (United States)

Kazis, Keren; Iglesias, Elba

2003-02-01

The female athlete triad is a syndrome consisting of disordered eating, amenorrhea, and osteoporosis. The syndrome is increasing in prevalence as more women are participating in sports at a competitive level. Behaviors such as intense exercise or disordered eating patterns can lead to dysregulation of the hypothalamic-pituitarian-ovarian (HPO) axis, resulting in amenorrhea. Hypothalamic amenorrhea can lead to osteoporosis and increased fracture risk. Adolescents may particularly be at risk because it is during this crucial time that females attain their peak bone mass. Prevention of the female athlete triad through education and identification of athletes at risk may decrease the incidence of long-term deleterious consequences. Treatment of the female athlete triad is initially aimed at increasing caloric intake and decreasing physical activity until there is resumption of normal menses. Treatment of decreased bone mineral density and osteoporosis in the adolescent population, however, is controversial, with new treatment modalities currently being investigated in order to aid in the management of this disorder.

The accumulated organic residues in tannery-plant courtyards are an eating attraction to small rodents; however, the contact of these animals with these residues may change their social behavior. Thus, the aim of the present study is to investigate whether the exposure to tannery effluent (TE) can damage the social recognition memory of female Swiss mice, as well as to assess whether vitamin C supplementation could provide information about how TE constituents can damage these animals' memory. We have observed that resident females exposed to TE (without vitamin supplementation) did not explore the anogenital region, their body or chased intruding females for shorter time or with lower frequency during the retest session of the social recognition test, fact that indicates social recognition memory deficit in these animals. Such finding is reinforced by the confirmation that there was no change in the animals' olfactory function during the buried food test, or locomotor changes in females exposed to the pollutant. Since no behavioral change was observed in the females exposed to TE and treated with vitamin C (before or after the exposure), it is possible saying that these social cognitive impairments seem to be directly related to the imbalance between the cellular production of reactive oxygen species and the counteracting antioxidant mechanisms (oxidative stress) in female mice exposed to the pollutant (without vitamin supplementation). Therefore, the present study evidences that the direct contact with tannery effluent, even for a short period-of-time, may cause short-term social memory deficits in adult female Swiss mice.

Receptive females mitigate costs of sexual conflict.

Science.gov (United States)

Harano, T

2015-02-01

Males typically gain fitness from multiple mating, whereas females often lose fitness from numerous mating, potentially leading to sexual conflict over mating. This conflict is expected to favour the evolution of female resistance to mating. However, females may incur male harassment if they refuse to copulate; thus, greater female resistance may increase costs imposed by males. Here, I show that the evolution of resistance to mating raises fitness disadvantages of interacting with males when mating is harmful in female adzuki bean beetles, Callosobruchus chinensis. Females that were artificially selected for higher and lower remating propensity evolved to accept and resist remating, respectively. Compared with females that evolved to accept remating, females that evolved to resist it suffered higher fitness costs from continuous exposure to males. The costs of a single mating measured by the effect on longevity did not differ among selection line females. This study indicates that receptive rather than resistant females mitigate the fitness loss resulting from sexual conflict, suggesting that even though mating is harmful, females can evolve to accept additional mating. © 2014 European Society For Evolutionary Biology.

The female condom: controlled by women.

Science.gov (United States)

1995-09-01

The polyurethane female condom is stronger than the latex male condom. Thus, the single-use female condom is less likely to break and has a longer shelf life than the single-use male condom. The ring at the closed end of the condom helps women insert the condom and secures the condom inside the vagina. The outer ring remains outside the vagina and protects the labia and the base of the penis. Female condom use reduces the likelihood of transmission of infectious diseases. The female condom is as effective at preventing pregnancy as the male condom and the diaphragm. Its life-table pregnancy rate in a multicenter clinical trial in the US and Latin America was 15.1% (12.4% in US and 22.% in Latin America). The 6-month failure rate during perfect use was 4.3%. In laboratory studies, no sexually transmitted organism, including HIV, penetrated the female condom. In a human use study, 14% of controls and 14.7% of non-perfect users were reinfected with trichomonas while none of the perfect users were reinfected. Advantages of the female condom follow: allows for greater sensitivity and greater protection than the male condom, is controlled by the female, can be used with any lubricant (even oil-based lubricants), and can be inserted well before intercourse. Disadvantages include cost (5 times costlier than the male condom), unsightly coverage of female genitalia, noisy during use, and breakage (although breakage rates were lower than for latex condoms: 1% vs. 2-5%). Method acceptability studies among various populations show that the inner rings and movement of the female condom during use were the most common complaints. Many women liked the female condom and would recommend it to others. Only a few women complained about insertion problems, yet it took some women at least two tries to insert the female condom.

Tamoxifen users sometimes seek complementary and alternative medicine advice for treatment of a variety of illness and co-administer with phytoestrogen-containing herbs, resulting in an increasing concern of its influence in subsequent endometrial cancer risk. Our study aims to determine the prevalence of Chinese herbal products containing coumestrol, genistein, or daidzein and their association with subsequent endometrial cancer risk among tamoxifen-treated breast cancer survivors in Taiwan. We selected all patients who were newly diagnosed with invasive breast cancer and received tamoxifen treatment between January 1, 1998, and December 31, 2008, from the National Health Insurance Research Database. Among the 26,656 tamoxifen-treated breast cancer survivors, we evaluated the usage, frequency of service, and prescription of Chinese herbal products containing coumestrol, genistein, or daidzein. The logistic regression method was employed to calculate the odds ratios for utilization of those herbal products. Cox proportional hazard regression was set to calculate the hazard ratios of endometrial cancer associated with such usage. Of the patients surveyed, 36.2% (n=9652) of the tamoxifen-treated breast cancer survivors examined in the study had consumed Chinese herbal products containing coumestrol, genistein, or daidzein during the study period. Exposure to Ge Gen(Puerariae Radix) specifically was the most extensive. For it, the population consumed an average cumulative dose of above 180g. Compared to those who had never used Chinese herbal products, breast cancer survivors who had taken Chinese herbal products containing coumestrol, genistein, or daidzein concurrently with tamoxifen treatment did not have a higher hazard ratio for subsequent development of endometrial cancer. Among those tamoxifen-treated female breast cancer survivors in Taiwan, consumption of Chinese herbal products containing coumestrol, genistein, or daidzein is negatively correlated with

Female infertility

Infertility, defined as 1 year of unprotected intercourse without conception, is becoming of increasingly important medical concern. Fertility in both the male and the female is at its peak in the twenties. Many couples today have postponed marriage and/or childbearing into their 30s until careers are established, but at that point fertility may be diminished. The current epidemic of venereal disease has been associated with an increasing incidence of tubal scarring. In addition, the use of intrauterine devices (IUDs) and birth control pills for contraception have let to later problems with pelvic inflammatory disease (PID) and ovulation disturbances. The problem of infertility intensifies as the number of babies available for adoption decreases. Therefore, it is estimated that approximately 10-20% of couples will eventually seek medical attention for an infertility-related problem. Fortunately, marked improvements in the results of tubal surgery are concurrently occurring secondary to refinements in microsurgical techniques, and many medical alternatives to induce ovulation are being developed. The male factor causes infertility in 30-40 % of couples, and the female factor is responsible in approximately 50% of couples. No cause is found in 10-20% of couples. This chapter discusses the role of coordinated imaging in the diagnosis and therapy of infertility in the female

To elucidate the perceived treatment that the homeless have received from the healthcare and other societal organisations and to present homeless persons' trust in the healthcare system and suggestions of necessary changes for improving it. Homeless individuals in special houses and institutions in the County of Stockholm were asked to answer a short version of a public health survey, including added questions about how they experienced the healthcare providers' attitudes towards them and how much trust they had in the healthcare system. A total of 155 homeless persons (123 male and 32 female) were interviewed. Three-quarters of the participants stated that they had fairly or very high trust in healthcare services and also felt that they had been fairly or very well treated. Fewer females than males reported being treated well and they declared a lower degree of trust in the healthcare system. The homeless suggest that extra resources be set aside to organise their healthcare, including a higher level of knowledge of the medical problems prevailing in the group. Those who felt badly treated also asked for less neglect and disrespect from the healthcare staff. Even though a majority experience that they are being well treated within the healthcare system, the study also indicated disadvantages in the treatment of homeless persons in Sweden. The study also reveals an imbalance between the official ethical framework in Sweden and of the specific moral of some individual healthcare providers. One way to facilitate their entry into the healthcare system might be to create special surgeries for the homeless.

Male depression in females?

Möller-Leimkühler, Anne Maria; Yücel, Mete

2010-02-01

Scientific evidence for a male-typed depression ("male depression") is still limited, but mainly supports this concept with respect to single externalizing symptoms or symptom clusters. In particular, studies on non-clinical populations including males and females are lacking. The present study aims at assessing general well-being, the risk and the symptoms of male depression dependent on biological sex and gender-role orientation on instrumental (masculine) and expressive (feminine) personality traits in an unselected community sample of males and females. Students (518 males, 500 females) of the Ludwig-Maximilians-University of Munich, Germany, were asked to participate in a "stress study" and complete the following self-report questionnaires: the WHO-5 Well-being Index [Bech, P., 1998. Quality of Life in the Psychiatric Patient. Mosby-Wolfe, London], the Gotland Scale for Male Depression [Walinder, J., Rutz, W., 2001. Male depression and suicide. International Clinical Psychopharmacology 16 (suppl 2), 21-24] and the German Extended Personal Attribute Questionnaire [Runge, T.E., Frey, D., Gollwitzer, P.M., et al., 1981. Masculine (instrumental) and feminine (expressive) traits. A comparison between students in the United States and West Germany. Journal of Cross-Cultural Psychology 12, 142-162]. General well-being of the students was significantly lower compared to population norms. Contrary to expectations, female students had a greater risk of male depression than male students (28.9% vs. 22.4%; p<0.05). Overall, prototypic depressive symptoms as well as externalizing symptoms were more pronounced in females. In the subgroup of those at risk for male depression, biological sex and kind of symptoms were unrelated. Principal component analyses revealed a similar symptom structure for males and females. Low scores on masculinity/instrumentality significantly predicted higher risk of male depression, independent of biological sex. The study sample is not

Desire and the female analyst.

Schaverien, J

1996-04-01

The literature on erotic transference and countertransference between female analyst and male patient is reviewed and discussed. It is known that female analysts are less likely than their male colleagues to act out sexually with their patients. It has been claimed that a) male patients do not experience sustained erotic transferences, and b) female analysts do not experience erotic countertransferences with female or male patients. These views are challenged and it is argued that, if there is less sexual acting out by female analysts, it is not because of an absence of eros in the therapeutic relationship. The literature review covers material drawn from psychoanalysis, feminist psychotherapy, Jungian analysis, as well as some sociological and cultural sources. It is organized under the following headings: the gender of the analyst, sexual acting out, erotic transference, maternal and paternal transference, gender and power, countertransference, incest taboo--mothers and sons and sexual themes in the transference.

Perspective for Female Medical Physicists

International Nuclear Information System (INIS)

Naqvi, Syed Mansoor; Hasnain, Aziz Fatima

2009-01-01

Due to cultural and religious reasons, Pakistani women can be reluctant to seek medical attention for disorders affecting their genitals or breasts. As a result, in the case of cervical and breast cancers, oncological treatment is often not received until the diseases are in the late stages. Once a cancer is classified and the tumor marked, the role of the medical physicist begins. Medical physicists' responsibilities include treatment planning, supervising treatment through radiation, dosimetry, contouring, training, equipment selection, education, research, and supervising radiotherapy facilities. In brachytherapy, isotopes are placed at the tumor site in the form of wires or seeds. There are very few female medical physicists in Pakistan. This leads to further hesitation on the part of many women to seek treatment. To help female patients obtain needed medical care, female physics students should be encouraged to pursue the emerging field of medical physics. This would provide a new professional opportunity for female physics students and give comfort to female patients.

Taxing sin and saving lives: Can alcohol taxation reduce female homicides?

Durrance, Christine Piette; Golden, Shelley; Perreira, Krista; Cook, Philip

2011-07-01

With costs exceeding $5.8 billion per year, violence against women has significant ramifications for victims, their families, the health care systems that treat them, and the employers who depend on their labor. Prior research has found that alcohol abuse contributes to violence against both men and women, and that stringent alcohol control policies can reduce alcohol consumption and in turn some forms of violence. In this paper, we estimate the direct relationship between an important alcohol control measure, excise taxes, and the most extreme form of violence, homicide. We use female homicide rates as our measure of severe violence, as this measure is consistently and accurately reported across multiple years. Our results provide evidence that increased alcohol taxes reduce alcohol consumption and that reductions in alcohol consumption can reduce femicide. Unfortunately, a direct test of the relationship does not have the power to determine whether alcohol taxes effectively reduce female homicide rates. We conclude that while alcohol taxes have been shown to effectively reduce other forms of violence against women, policy makers may need alternative policy levers to reduce the most severe form of violence against women.

Severe progressive scoliosis in an adult female possibly secondary thoracic surgery in childhood treated with scoliosis specific Schroth physiotherapy: Case presentation.

Science.gov (United States)

Lebel, Andrea; Lebel, Victoria Ashley

2016-01-01

Scoliosis is a complex three-dimensional (3D) spinal deformity. Acquired scoliosis in early childhood may progress into adulthood and pose an increased risk of health problems and reduction in quality of life. In Canada, patients with scoliosis are not referred for physiotherapeutic scoliosis-specific exercises (PSSE) despite the fact that Schroth physiotherapy, a scoliosis-specific 3D posture training and exercise program, can be effective in reducing pain and improving scoliosis curves, vital capacity, and overall quality of life in scoliosis patients. This case presentation shows that indeed adult curve progression can be stopped and even reversed with scoliosis specific Schroth physiotherapy (SSSPT) in an adult patient with scoliosis. This is a retrospective case presentation involving a 23-year-old female scoliosis patient who began an outpatient Schroth physiotherapy exercise program and was initially monitored monthly and then annually for improvement in measurements of angle of trunk rotation (ATR) and chest expansion and improvement in vital capacity measured with incentive spirometry. Photos were taken to document body image periodically throughout Schroth physiotherapy treatment. Additionally, the patient completed SRS-22 quality of life questionnaires every 2 years to evaluate daily function, pain, self-imagine, mental health, and scoliosis management satisfaction. Within one month of beginning SSSPT, the patient reported no more back pain and within 2 months, reported improved breathing. The patient also benefitted from improved chest expansion, reduced scoliosis curve angles (measured in Cobb degrees), increased vital capacity, decreased ATR, and higher SRS-22 scores. She became more active and resumed all athletic activity within 8 months of beginning Schroth physiotherapy. Adult scoliosis patients are not routinely referred for PSSE in Canada, even though Schroth physiotherapy, a form of PSSE, is shown to be effective in this case presentation

Full Text Available Abstract Background Scoliosis is a complex three-dimensional (3D spinal deformity. Acquired scoliosis in early childhood may progress into adulthood and pose an increased risk of health problems and reduction in quality of life. In Canada, patients with scoliosis are not referred for physiotherapeutic scoliosis-specific exercises (PSSE despite the fact that Schroth physiotherapy, a scoliosis-specific 3D posture training and exercise program, can be effective in reducing pain and improving scoliosis curves, vital capacity, and overall quality of life in scoliosis patients.

ABSTRACT This project explores the phenomenon of North American and Western European women, who travel to the Global South and engage in sexual encounters with the local men. This project has positioned itself as a postcolonial critique, arguing that female sex tourism is a form of neocolonialism. It has also investigated the term romance tourism, where it has found that as a result of essentialist gender stereotyping, the female version of sex tourism has been titled ‘romance tourism’.

The Role Model Effect on Gender Equity: How are Female College Students Influenced by Female Teaching Assistants in Science?

Ebert, Darilyn

The gender gap of women in science is an important and unresolved issue in higher education and occupational opportunities. The present study was motivated by the fact that there are typically fewer females than males advancing in science, and therefore fewer female science instructor role models. This observation inspired the questions: Are female college students influenced in a positive way by female science teaching assistants (TAs), and if so how can their influence be measured? The study tested the hypothesis that female TAs act as role models for female students and thereby encourage interest and increase overall performance. To test this "role model" hypothesis, the reasoning ability and self-efficacy of a sample of 724 introductory college biology students were assessed at the beginning and end of the Spring 2010 semester. Achievement was measured by exams and course work. Performance of four randomly formed groups was compared: 1) female students with female TAs, 2) male students with female TAs, 3) female students with male TAs, and 4) male students with male TAs. Based on the role model hypothesis, female students with female TAs were predicted to perform better than female students with male TAs. However, group comparisons revealed similar performances across all four groups in achievement, reasoning ability and self-efficacy. The slight differences found between the four groups in student exam and coursework scores were not statistically significant. Therefore, the results did not support the role model hypothesis. Given that both lecture professors in the present study were males, and given that professors typically have more teaching experience, finer skills and knowledge of subject matter than do TAs, a future study that includes both female science professors and female TAs, may be more likely to find support for the hypothesis.

Much research has explored the experience of erectile dysfunction (ED) among men with ED, but far less attention has been paid to the perceptions and sexual experiences of the female partners of men with ED. The objective of this study was to characterize the attitudes, beliefs, and sexual experience of female partners of men with erectile difficulties. Female partners of men with ED who had participated in the Men's Attitudes to Life Events and Sexuality (MALES) study were recruited for this research via mail or Internet, after their male partners consented to this contact. Female partners of men with ED (N = 293) responded to questionnaire measures assessing their frequency of sexual activity and the nature of their sexual experience, both before and after the development of their partner's ED, and in relation to their partner's use of phosphodiesterase type 5 (PDE5) inhibitors. Women reported engaging in sexual activity significantly less frequently after their partner developed ED in comparison with before (P effects on the female partner's sexual experience. Women with partners who were currently using PDE5 inhibitors had a more satisfying sexual experience than those whose partners did not use a PDE5 inhibitor.

The purpose of this study was to investigate the pretreatment effect of garlic on hepatotoxicity and oxidative stress induced by thioacetamide (TAA) in female albino rats.Sixty female adult albino rats were assigned equally into four groups; control group: animals without treatment, group ?: rats given daily oral dose of 250 mg/ kg garlic for 28 days, group ??: rats injected intraperitonealy by thioacetamide 20 mg ? kg for two weeks and group III: rats given 250 mg / kg garlic orally for 28 day followed by intrapertoneal injection of 20 mg / kg thioacetamide for two weeks. Liver enzymes were evaluated by measurements of AST, ALT and alkaline phosphatase and also trace elements (Cu and Zn) were estimated. Superoxide dismutase, glutathione peroxidase, malondialdehyde and thyroid hormones (T3 and T4) were assessed. Also, histological studies on liver and stomach were carried out. The results indicated that treatment with garlic significantly decreased liver enzymes (AST, ALT and ALP). Cu showed high significant increase in groups treated with garlic and also garlic + TAA, while Zn was increased significantly in TAA group. Superoxide dismutase (SOD) was increased significantly in group I while TAA decreased it significantly. Glutathione peroxidase was decreased significantly in group II while its level in group IV reached near the control value. Similarly, malondialdehyde was decreased significantly in garlic group and garlic ameliorated the thioacetamide effect in garlic + TAA group. The treatment with TAA led to significant increase in T3 and significant decrease in T4 hormones. Garlic ameliorated T3 level to reach the control level. Histologically, pre-treatment with garlic induced a prophylactic activity against the thioacetamide in liver and stomach tissues.According to the obtained results, it could be conclude that garlic treatment may act as antioxidant or pro-oxidant in TAA treated animals besides decreasing the TAA toxic effects on liver enzymes, liver and

Lifetime number of mates interacts with female age to determine reproductive success in female guppies.

Full Text Available In many species, mating with multiple males confers benefits to females, but these benefits may be offset by the direct and indirect costs associated with elevated mating frequency. Although mating frequency (number of mating events is often positively associated with the degree of multiple mating (actual number of males mated, most studies have experimentally separated these effects when exploring their implications for female fitness. In this paper I describe an alternative approach using the guppy Poecilia reticulata, a livebearing freshwater fish in which females benefit directly and indirectly from mating with multiple males via consensual matings but incur direct and indirect costs of mating as a consequence of male sexual harassment. In the present study, females were experimentally assigned different numbers of mates throughout their lives in order to explore how elevated mating frequency and multiple mating combine to influence lifetime reproductive success (LRS and survival (i.e. direct components of female fitness. Under this mating design, survival and LRS were not significantly affected by mating treatment, but there was a significant interaction between brood size and reproductive cycle (a correlate of female age because females assigned to the high mating treatment produced significantly fewer offspring later in life compared to their low-mating counterparts. This negative effect of mating treatment later in life may be important in these relatively long-lived fishes, and this effect may be further exacerbated by the known cross-generational fitness costs of sexual harassment in guppies.
