Human chorionic gonadotropin in vitro: Effects on rat sperm motility and fertilization outcome

引用

Asian pacific Journal of Reproduction 2018年第5期7卷 225-228页

作者： seyed Mansour Moosavi hossein Barzegar Ganji Hajar Ramezanikhah Mitra Arianmanesh Department of Anatomical Sciences School of MedicineZanjan University of Medical SciencesZanjanIran

Objective:To investigate the effect of human chorionic gonadotropin (hCG) on the motility of rat sperm and the fertilization rate following in vitro fertilization. Methods: hCG concentrations of 25, 50, 75 and 100 ng/mL with incubation time of 1 h and 2 h were used in medium to study sperm motility. Then, 25 and 100 ng/mL of hCG with incubation time of 2 h were applied for in vitrofertilization. After 6 h, the number of two pronuclei was counted. Obtained data was subjected to one way ANOVA and Bonferroni-Dun hoc-post ***:Total motility and progressive motility of sperms were increased significantly (P<0.05) in hCG experimental group with concentration of 25 ng/L and incubation time of 2 h compared to control group, however, total motility and progressive motility of sperms were decreased significantly (P<0.05) with increasing dose of hCG. Fertilization rate was decreased significantly (P<0.05) in hCG experimental group with dose of 100 ng/mL compared to 25 ng/mL and control group. Conclusions:The effect of hCG on the rat sperm motility and the rate of their fertility is dose-dependent so that hCG with dose of 25 ng/mL leads to an increase in rat sperm motility and to some extent fertilization rate.

Lateral rectus muscle recession and the vertical palpebral fissure height: to do or not to do inter-muscular septum dissection?

引用

International Journal of Ophthalmology(English edition) 2018年第6期11卷 1053-1055页

作者： Mohammad Ali Abtahi Alireza Zandi Eslam Mandegarfard Hamidreza Jahanbani-Ardakani Behzad Mahaki seyed-hossein Abtahi Isfahan Eye Research Center Feiz Hospital Isfahan University of Medical Sciences Department of Ophthalmology Feiz Hospital Isfahan University of Medical Sciences Isfahan Medical Students Research Center Isfahan University of Medical Sciences Department of Biostatistics School of Health Kermanshah University of Medical Sciences

In this study, we aimed to evaluate changes of vertical palpebral fissure height （VPFH） after unilateral lateral rectus muscle recession. Twenty-five and twenty-six patients who were candidates for lateral rectus muscle recession were assigned into “with” and “without” intermuscular septum dissection study arms. The VPFH was measured at one-day before surgery and in two weeks and three months, postoperatively. Three months after surgery, significant increase of VPFH was observed in both groups （Paired t-test; P=0.005）. Also, less widening of VPFH was observed in “with intermuscular septum dissection” group （Change in VPFH in “with intermuscular septum dissection” vs “without intermuscular septum dissection” groups： 0.48 mm vs 1.34 mm; ANCOVA test; P〈0.001）. However, such results were not observed two weeks post-operatively （Change in VPFH in “with intermuscular septum dissection” vs “without intermuscular septum dissection” groups： -0.28 mm vs 0.28 mm; ANCOVA test; P=0.302）. Intermuscular septum dissection is recommended in lateral rectus muscle recession to partially prevent the undesirable increment of VPFH.

地质分层是石油工程中的一项重要的基础工作。叠后地震数据和测井数据的时间序列能反映地下分层。由于地层的非均质性和不同成因特性,它们表现出具有复杂模式的多重分形特性。在多重分形结构中,序列中的任何部分都具有不同的赫斯特(Hurst)指数,可反映其性质,并可用于分区检测。时间序列是井眼附近的叠后地震道和测井数据。自相似自回归外生(SAE)模型是一种改进的方法,它可以将自相似的叠后地震和测井段置于具有相同岩性的地层之间,这样就可以通过SAE模型对地震数据进行分层识别。
