Aims: Although the copper intrauterine device (Cu-IUD) is an effective contraceptive device, cases of pregnancy under the Cu-IUD have been reported. We here report 10 women who got pregnant under this condition, with special reference to etiologies and pregnancy outcomes. Methodology: We analyzed all women who got pregnant under Cu-IUD at ATBEF Main Clinic from July 1, 2015 to June 30, 2020. Results: We retrieved 10 patients. The durations of Cu-IUD use were 3 months to 6 years. The etiologies were poor insertion;migration and spontaneous expulsion. The occurrence of pregnancy was poorly accepted by the women: 20% of women considered it was due to the providers’ incompetence. Of the 10 pregnancies, 5 women had given vaginal birth spontaneously;2 induced abortions, 2 spontaneous abortions and 1 ectopic pregnancy. The contraceptive method adopted after pregnancy was jadelle implants in 8 cases and spousal vasectomy in 2 cases. Conclusion: The prevention of IUD pregnancies may require adequate insertion time, insertion technique and follow-up.

Background: The use of modern contraceptive methods contributes to the reduction of maternal and neonatal mortality. The initiation of a contraceptive method in the immediate postpartum period is one of the strategies to avoid missing out on contraceptive opportunities. This strategy will reduce the unmet need for contraception which is still high in the country. Objective: To describe the knowledge and attitudes of pregnant women and the practices of women who have given birth about immediate postpartum contraception. Methodology: This was a cross-sectional and descriptive study conducted at the main clinic of ATBEF from 20th March to 20th October 2020. Our study included pregnant women whose gestational age was greater than or equal to 37 weeks of amenorrhea who came for prenatal consultation or for any other consultation and then gave birth in the center. Data collection was based on a survey form. Data analysis and entry was done with the Epi info 2000 version 6.04 software. The parameters studied were: socio-demographic characteristics, knowledge and attitudes of pregnant women about contraception in the immediate postpartum period, and contraceptive practices of the women who gave birth.

Ethinyl estradiol（EE） as a contraceptive,（17α）-19-nopregna-1,3,5-（10）-trien-20-yne-3,17-diol（formula： C（20）H（24）O2, molecular weight： 296.4, CAS number： 57-63-6）, is known to have different pseudo-polymorphic forms. Some EE polymorphs have been synthesized by means of physical or chemical methods, characterized by X-ray powder diffraction（XRPD）, thermogravimetric（TG）, differential scanning calorimetry（DSC） and IR spectra. Dissolution profile was tested by high performance liquid chromatography（HPLC）. Meanwhile, the crystal structure of the new EE solvate（formamide） was characterized by single-crystal X-ray structure analysis（SXRD）. The results confirmed that EE existed polymorphism. Five crystal forms of EE were presented and two of them were reported firstly. Furthermore, five polymorphs＇ dissolution curves were drawn and they could be identified by several analysis methods. Our study on polymorphs of EE could provide a variety of crystal material composition, preparation methods and solubility.

Polymorph screening is currently one of the most important tasks for innovators and for generic companies from both pharmaceutical and intellectual property rights aspects. The hemihydrate form（Form Ⅰ） and formamide solvate（Form Ⅱ） of estradiol are isolated and prepared via systemic crystallization screening in this paper, and the formamide solvate form is reported for the first time. Both polymorphic forms were characterized by single-crystal X-ray structure analysis（SXRD）, powder X-ray diffraction（PXRD）, and thermal analysis（TGA and DSC）. The PXRD experiments indicate that the samples in this study are the pure polymorphic forms via comparing the patterns with the simulated ones. The stability and equilibrium solubility data of the solid-state phase were also examined in order to check the impact of the differences observed in their crystalline structures. It has been found that Forms I and II are of conformational polymorph and Form II is the more thermodynamically stable solid form, while Form I possesses higher solubility, indicating its possibility as an alternate solid form for its further solid formulation development if necessary.

Because of unavoidable complications of vasectomy, this study was undertaken to assess the efficacy and safety of male sterilization with a nonobstructive intravas device （IVD） implanted into the vas lumen by a mini-surgical method compared with no-scalpel vasectomy （NSV）. IVDs were categorized into two types： IVD-B has a tail used for fixing to the vas deferens （fixed wing） whereas IVD-A does not. A multicenter prospective randomized controlled clinical trial was conducted in China. The study was comprised of 1459 male volunteers seeking vasectomy who were randomly assigned to the IVD-A （n = 487）, IVD-B （n = 485） or NSV （n = 487） groups and underwent operation. Follow-up included visits at the 3rd-6TM and 12~ postoperative months, The assessments of the subjects involved regular physical examinations （including general and andrological examinations） and semen analysis. The subjects＇ partners also underwent monitoring for pregnancy by monthly interviews regarding menstruation and if necessary, urine tests, There were no significant differences in pregnancy rates （0.65% for IVD-A, 0 for IVD-B and 0.21% for NSV） among the three groups （P 〉 0.05）. The cumulative rates of complications at the 12th postoperative month were zero, 0.9% and 1.7% in the three groups, respectively. In conclusion, IVD male sterilization exhibits a low risk of long-term adverse events and was found to be effective as a male sterilization method, similar to the NSV technique. IVD male sterilization is expected to be a novel contraceptive method.

The N-terminal EF-hand calcium-binding proteins 1–3(NECAB1–3) constitute a family of predominantly neuronal proteins characterized by the presence of at least one EF-hand calcium-binding domain and a functionally less well characterized C-terminal antibiotic biosynthesis monooxygenase domain. All three family members were initially discovered due to their interactions with other proteins. NECAB1 associates with synaptotagmin-1, a critical neuronal protein involved in membrane trafficking and synaptic vesicle exocytosis. NECAB2 interacts with predominantly striatal G-protein-coupled receptors, while NECAB3 partners with amyloid-β A4 precursor protein-binding family A members 2 and 3, key regulators of amyloid-β production. This demonstrates the capacity of the family for interactions with various classes of proteins. NECAB proteins exhibit distinct subcellular localizations: NECAB1 is found in the nucleus and cytosol, NECAB2 resides in endosomes and the plasma membrane, and NECAB3 is present in the endoplasmic reticulum and Golgi apparatus. The antibiotic biosynthesis monooxygenase domain, an evolutionarily ancient component, is akin to atypical heme oxygenases in prokaryotes but is not wellcharacterized in vertebrates. Prokaryotic antibiotic biosynthesis monooxygenase domains typically form dimers, suggesting that calcium-mediated conformational changes in NECAB proteins may induce antibiotic biosynthesis monooxygenase domain dimerization, potentially activating some enzymatic properties. However, the substrate for this enzymatic activity remains uncertain. Alternatively, calcium-mediated conformational changes might influence protein interactions or the subcellular localization of NECAB proteins by controlling the availability of protein–protein interaction domains situated between the EF hands and the antibiotic biosynthesis monooxygenase domain. This review summarizes what is known about genomic organization, tissue expression, intracellular localization, interac

Sperm DNA damage is recognized as an important biomarker of male infertility. To investigate this, sperm DNA damage was assessed by the sperm chromatin dispersion （SCD） test in semen and motile spermatozoa harvested by combined density gradient centrifugation （DGC） and swim-up in 161 couples undergoing in vitro fertilization （IVF）. Semen analysis and sperm DNA damage results were compared between couples who did or did not achieve pregnancy. The sperm DNA damage level was significantly different between the two groups （P 〈 0.05） and was negatively correlated with IVF outcomes. Logistic regression analysis confirmed that it was an independent predictor for achieving clinical pregnancy. The effects of different levels of sperm DNA damage on IVF outcomes were also compared. There were significant differences in day 3 embryo quality, blastocyst formation rate, and implantation and pregnancy rates （P 〈 0.05）, but not in the basic fertilization rate between the two groups. Thus, sperm DNA damage as measured by the SCD appears useful for predicting the clinical pregnancy rate following IVF.
