Background In poultry, the smooth transition of follicles from the preovulatory-to-postovulatory phase impacts egg production in hens and can benefit the poultry industry. However, the regulatory mechanism underlying follicular ovulation in avians is a complex biological process that remains unclear.Results Critical biochemical events involved in ovulation in domestic chickens(Gallus gallus) were evaluated by transcriptomics, proteomics, and in vitro assays. Comparative transcriptome analyses of the largest preovulatory follicle(F1) and postovulatory follicle(POF1) in continuous laying(CL) and intermittent laying(IL) chickens indicated the greatest difference between CL_F1 and IL_F1, with 950 differentially expressed genes(DEGs), and the smallest difference between CL_POF1 and IL_POF1, with 14 DEGs. Additionally, data-independent acquisition proteomics revealed 252 differentially abundant proteins between CL_F1 and IL_F1. Perivitelline membrane synthesis, steroid biosynthesis, lysosomes, and oxidative phosphorylation were identified as pivotal pathways contributing to ovulation regulation. In particular, the regulation of zona pellucida sperm-binding protein 3, plasminogen activator, cathepsin A, and lactate dehydrogenase A(LDHA) was shown to be essential for ovulation. Furthermore, the inhibition of LDHA decreased cell viability and promoted apoptosis of ovarian follicles in vitro.Conclusions This study reveals several important biochemical events involved in the process of ovulation, as well as crucial role of LDHA. These findings improve our understanding of ovulation and its regulatory mechanisms in avian species. 展开更多

Objective: Since not all women wish to conceive a child through aggressive treatment, we investigated the usefulness of modified repeated intracyclic clomiphene citrate (CC) therapy (repeated CC therapy) as a newly devised administration method. Methods: We evaluated the effects of CC administration on menstrual cycle length and retrospectively compared ovulation and pregnancy in 220 women who received CC at our hospital. Patients in the conventional method group received 50 mg per day for five days, starting on the fifth day of menstruation (withdrawal bleeding). Groups with and without menstrual cycle shortening after conventional CC administration were compared. The repeated CC therapy group was also compared with the non-shortened group. Repeated CC therapy was administered for the first five days as in the conventional method, and a second five-day repeat treatment was administered after an interval of five to seven days. Pregnancy rates, including indirect pregnancies, were evaluated by three different methods. Results: Ovulation and pregnancy rates were significantly better in the shortened group than in the non-shortened group (P < 0.001 and P = 0.010, respectively). Even in the non-shortened group, ovulation and pregnancy rates including indirect pregnancies were significantly improved when ovulation was observed with repeated CC therapy (P < 0.001 and P = 0.022, respectively). Conclusions: For patients whose menstrual cycle was not improved or shortened, repeated CC therapy as the newly devised CC administration method is useful as the next step after the conventional CC administration method. 展开更多

Objective: To observe the therapeutic effect of combined traditional Chinese medicine (TCM) therapy with acupoint injection and herbal patch application on patients with ovulatory dysfunction associated with polycystic ovary syndrome (PCOS). Methods: A total of 80 PCOS patients who received treatment at the First Affiliated Hospital of Guangxi University of Chinese Medicine between October 2022 and March 2024 were enrolled in this study. They were randomly divided into a control group (n = 40) and an observation group (n = 40). The control group received conventional Western medical treatments, while the observation group was administered TCM combined with acupoint injection and herbal patch application. Pre- and post-treatment conditions were compared between the two groups. Results: After treatment, the overall effective rate was significantly higher in the observation group compared to the control group (P 0.05). Following treatment, both ovulation and pregnancy rates increased in both groups, but the increase was more evident in the observation group, showing a statistically significant difference (P < 0.01). Conclusion: For patients with oligoovulation or anovulation due to PCOS, the combined use of TCM, acupoint injection, and herbal patch application appears to be effective in improving systemic symptoms and achieving notable clinical outcomes. 展开更多

Three-dimensional(3D)printing technology has been widely used to create artificial rock samples in rock mechanics.While 3D printing can create complex fractures,the material still lacks sufficient similarity to natural rock.Extrusion free forming(EFF)is a 3D printing technique that uses clay as the printing material and cures the specimens through high-temperature sintering.In this study,we attempted to use the EFF technology to fabricate artificial rock specimens.The results show the physico-mechanical properties of the specimens are significantly affected by the sintering temperature,while the nozzle diameter and layer thickness also have a certain impact.The specimens are primarily composed of SiO_(2),with mineral compositions similar to that of natural rocks.The density,uniaxial compressive strength(UCS),elastic modulus,and tensile strength of the printed specimens fall in the range of 1.65–2.54 g/cm3,16.46–50.49 MPa,2.17–13.35 GPa,and 0.82–17.18 MPa,respectively.It is capable of simulating different types of rocks,especially mudstone,sandstone,limestone,and gneiss.However,the simulation of hard rocks with UCS exceeding 50 MPa still requires validation. 展开更多

[ Objective] To explore the effects of FSH ( Follicle-stimulating hormone), seasons and treatment frequency on super-ovulation in donor goats and to provide necessary data for research about embryo transfer and embryo biotechnology in Yangzhou area. [ Method] Two FSH dosages (240 and 300 I U), two seasons (April- June and October- December), and two treatment frequencies (one or two times) were used to induce super-ovulation in goats. [ Result] Both average ovulation point and number of transferable embryos were significantly different between the goats given 240 IU FSH and those given 300 lU FSH (average ovulation point, 10.12 vs 15.55; number of transferable embryos, 8.82 vs 13.15) at the 0.05 level. Both average ovulation point and number of transferable embryos were also significantly different between April -June and October- December ( average ovulation point, 9.05 vs 15.55; number of transferable embryos, 7.05 vs 13.15) at the 0.05 level. Super-ovulation effect was not significantly different between the two treatment frequencies.

In vitro gynogenesis is an important tool used in haploid or homozygous double-haploid plant breeding.However,because of low repeatability,embryoid induction rate and quality,the molecular mechanisms remain poorly understood.Heat shock treatment can promote the transformation of the gametophytic pathway into the sporophyte pathway,which induces the occurrence of haploid.In this study,unfertilized ovaries were heat shocked for 0 h(A0)before flowering and for 0 h(A1),4 h(A3),8 h(A5),12 h(A7),and 24 h(A8),respectively,at 37℃at the first day of the flowering stage.The ovule enlargement rate was increased from 0%at 25℃to 96.8%at 37℃(24 h treatment).Thus,we aimed to investigate the gene expression patterns in unfertilized ovules of watermelon after different periods of heat shock by using RNA-Seq technology.The results showed that compared with A3,A5,A7,and A8,the biosynthesis of amino acid,glycine,serine and threonine metabolic pathways in A1 has changed significantly.This indicated that heat shock treatment affected the synthesis and transformation of amino acids during ovule expansion.The transcriptome data suggested gene expressions of ovule growth were significantly changed by heat-specific influences.The results provide new information on the complex relationship between in vitro gynogenesis and temperature.This provides a basis for further study of the mechanism of heat shock affecting the expansion of watermelon ovule. 展开更多

Eight ewes of Hu sheep which bred multi-lamb were used as the high-fecundity group and the other eight ewes of Hu sheep which bred single lamb were used as the control group to investigate the relationship between the mRNA expression level of TGF-β receptor genes in tissues and ovulation rate in Hu sheep. Cloprostenol sodium was injected to make the synchronization of estrus treatment, then all ewes were slaughtered within 24-36 h after empathema and the ovaries were collected. Furthermore, the number of ovulation points was counted to determine ovulation rate for each sheep. Tissue expression analysis was conducted by RT-PCR for one ewe form the high-fecundity group and the relationship between the mRNA expression of genes encoding TGF-β receptors and ovulation rate was detected by real-time fluorescent quantitative PCR. The results showed that the relative expression level of TGF-flR I gene in the reproductive organ was significantly higher than in the lung and muscle (P 〈 0.01), while relative expression level of TGF-βR H in reproductive organ was significantly higher than that of other tissues (P 〈 0.01), indicating that these are highly expressed genes in the ovary. In addition, mRNA expression level of TGF-βR I and TGF-flRH in the ovaries of the high-fecundity group were significantly higher (P〈 0.01) and obviously higher (P= 0.011) than the control group, respectively. The mRNA expression level of TGF-βR I and TGF-βR H had a positive correlation with ovulation rate and the correlation coefficients were 0.562 (P〉 0.05) and 0.711 (P〈 0.05), respectively. It is suggested that TGF-β receptors have close relationship with highfecundity in Hu sheep. 展开更多

Background: The purpose of this study was to compare the effectiveness of Letrozole versus Clomiphene citrate for ovulation induction in polycystic ovarian syndrome (PCOS) with infertility. Methods: This was a prospective randomized trial involving 150 women with PCOS attending the Infertility Clinic at three hospitals in Malaysia. During the initial visit, anthropometric measurements and baseline investigations were performed. Patients were randomized to 5.0 mg Letrozole daily (75 patients) or 100 mg Clomiphene citrate daily (75 patients) from the fifth until the ninth day of menstruation. Serial transvaginal scans were performed to see the dominant follicles, endometrial thickness and number of follicles. Transvaginal scans were performed serially to look for evidence of ovulation. Results: The subjects were homogenously distributed. The difference between Letrozole and Clomiphene citrate for ovulation rate was 59 (78.7%) versus 40 (53.3%). Patients taking Letrozole exhibited a mean endometrial thickness (ET) at mid cycle of menses (Day 11-D14) of9.2 mm(SD ± 2.3) versus8.4 mm(SD ± 2.2) for patients taking Clomiphene citrate, and these differences were statistically significant 展开更多

The effect of rosiglitazone on endocrine, metabolism and ovulatory performance in the paitents with polycystic ovary syndrome(PCOS) and insulin resistance was investigated. Twenty-five patients diagnosed as having polycystic ovary syndrome (PCOS) combined with insulin resistance were treated with rosiglitazone for 12 weeks. Before and after treatment, serum luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2), testosterone (T), androstenedione (A), sex hormone binding globulin (SHBG), insulin and glucose concentration, total cholesterol, triglycerides (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholestero (LDL-C), apolipoprotein A, apolipoprotein B levels and ovulatory performance were determined. The results showed that after treatment serum insulin levels was decreased significantly (P<0.01). The HDL-C was increased while LDL-C decreased significantly (P<0.05, P<0.01). The serum LH, T, A concentrations and the ratio of LH/FSH were decreased, while SHBG levels increased significantly (P<0.01). The ovulation rate during clomiphene citrate therapy was 72 %, significantly higher than that before treatment. It is likely that reduction of hyperinsulinemia that is produce by rosiglitazone may effectively improve the endocrine, metabolism and ovulatory performance in the patients with PCOS and insulin resistance. 展开更多

BACKGROUND Hepatocellular adenoma(HCA) is a rare benign liver tumor usually affecting young women with a history of prolonged use of hormonal contraception.Although the majority is asymptomatic, a low proportion may have significant complications such as bleeding or malignancy. Despite responding to the hormonal stimulus, the desire for pregnancy in patients with small HCA is not contraindicated. However, through this work we demonstrate that intensive hormonal therapies such as those used in the treatment of infertility can trigger serious complications CASE SUMMARY A 33-year-old female with a 10-year history of oral contraceptive use was diagnosed with a hepatic tumor as an incidental finding in an abdominal ultrasound. The patient showed no symptoms and physical examination was unremarkable. Laboratory functional tests were within normal limits and tests for serum tumor markers were negative. An abdominal magnetic resonance imaging(MRI) was performed, showing a 30 mm × 29 mm focal lesion in segment VI of the liver compatible with HCA or Focal Nodular Hyperplasia with atypical behavior. After a total of six years of follow-up, the patient underwent ovulation induction treatment for infertility. On a following MRI, a suspected malignancy was warned and hence, surgery was decided. The surgical specimen revealed malignant transformation of HCA towards trabecular hepatocarcinoma with dedifferentiated areas. There was non-evidence of tumor recurrence after three years of clinical and imaging follow-up.,CONCLUSION HCAs can be malignant regardless its size and low-risk appearance on MRI when an ovultation induction therapy is indicated. 展开更多

The annual rate of pregnancy, discontinuation rate and continuation rate in the two groups was determined. The serum prolactin and estradiol in 90 breastfeeding mothers and urine estrogen and pregnanediol in different feeding mothers were measured.Results There were 219 subjects in the BOM group and 200 in the IUD group. The pregnancy rate in this two groups was 1. 43% and 1. 54% respectively. The rates of discontinuation and continuation in the IUD group were:8. 87% and 91. 35% as well as in the BOM group were 8. 53% and 90. 17% respectively. Neither result was statistically significant (P>0. 05). The experimtal research showed that menses return was well estimated by 0. 35 ratio of serum prolactin vs. estrodiol. Sensitivity and specificity was 94. 61% and 84. 61% respectively. It also indicated that (1) the levels of urine hormone were closely related to the patterns of cervical mucus and (2) the incidence of ovulating before the second return of menses in partially breastfeeding mothers was much lower than that of bottle-feeding mothers (47. 05% vs. 94. 20%). Conclusion BOM is a simple, reliable and well accepted contraceptive method of during breastfeeding. If it can be combined with the measurement of serum prolactin/ estradiol, the date of menses return will be determined more easily. Encouraging mothers to breast-feed will be beneficial to the health of both babies and mothers and delay the fertility return of mothers. 展开更多

Background: The response of ovaries during controlled ovarian stimulation is the most important factor for evaluating the pregnancy outcome in assisted reproductive techniques. Aim: The study is to assess the role of a nurse in giving induction of ovulation medications at assisted reproduction university center versus home medications by private In Vitro Fertilization and infertility center on clinical outcomes and patient satisfaction. Subjects and Methods: Case-control research design, conducted at two centers (Banon private center for IVF and Assisted Reproductive Unit at Women health hospital, Assiut University) during the period from February 2018 to November 2018. The sample size included 150 women undergoing IVF for each group. Results: There is no statistically significant difference between women given IVF medications by the nurse at the public IVF center and women take IVF medication in the home at Banon IVF center as regards the outcome of IVF. Majority of infertile patients are satisfied with the care, they received and nearly third of them are satisfied with outcome of IVF in both groups, and there is statistically significant difference between satisfaction in public IVF center and satisfaction in private center in relation to information provided about IVF procedure, staff willingness to listen carefully and help patients;regular progress update on condition is in place with p value (0.000, 0.005, 0.003) respectively. Conclusion: IVF outcome isn’t significantly related to where induction medication was taken either at IVF center or at the home because infertile couples are keen to comply with all instructions on how to take medications with correct route, correct dose and on time. Recommendations: Empower the role of nurse as a health educator for women undergoing IVF about importance of stage of induction and take medications with correct route, correct dose and on time on outcome of IVF;other studies should also be conducted in other centers to further investigate the issue. 展开更多

Objectives: To describe our management strategy of ovulation disorders. Patients and methods: From a retrospective collection of data from the records, we identified over a period of one year (January 2016-December 2016), 47 patients followed in gynecology department of University and Hospital Centers of Yopougon and Treichville in Abidjan (Cote d’Ivoire) for ovulation disorders. The diagnosis of dysovulation was made following a hormonal check up and a follicular monitoring ultrasound. These patients underwent a specific treatment according to the type of dysovulation they presented. Results: The average age was 31.9 years with a significant proportion of nulliparous (66%). Body mass index was high in 44.7% of patients, of whom 19.1% were obese and 25.6% overweight. The hormonal balance was disrupted in 48.9% of cases. Polycystic ovary syndrome (WHO type IIb dysovulation) was the most common pathology (36%). The proposed treatments were dominated by clomiphene citrate (31.9%) and gonadotrophins (25.5%). 14.9% of pregnancies were obtained. Conclusion: This study allows us to offer better management of ovulation disorders, but this necessarily entails a careful exploration and an appropriate treatment. 展开更多
