The effect of taurine on the turkey spermatozoa motility and viability during the in vitro incubation was assessed. Experimental samples were prepared by diluting the raw semen in nine different conce...
Li Y., Sun M., Zhu J., Jiao G., Lin J., Dong H., Tan J., Zhou J. (2017): Species difference in the expression of Fas and Fas ligand in mature mammalian spermatozoa. Czech J. Anim. Sci., 62, 519–526. ...
The objective of this study was to investigate the applicability of liquid chromatography coupled with high resolution product scan (LC/HRPS) mass spectrometry for simultaneous quantification of adeni...
Cryopreservation of caudal epididymal spermatozoa is an effective technique to conserve genetic potentials of superior dogs when it is not possible to collect ejaculated spermatozoa. Although hen egg ...
Proteases and protease inhibitors play key roles in most physiological processes, including cell migration, cell signaling, and cell surface and tissue remodeling. Among these, the matrix metalloprote...
The sex-determining region on the Y (SRY) gene is important in mammalian sex determination and differentiation. We report a study of the abundance of SRY gene products in bovine ejaculate. RT-PCR expe...
The present study was conducted to investigate the effects of butylated hydroxytoluene (BHT) supplementation on diluted, cooled and frozen-thawed ram spermatozoa. After primary evaluation of collected...
The present study was conducted to observe the effect of increased osmolality of basic tris extender supplemented with trehalose and sucrose on post-thawing quality (motility, progressive motility, vi...
An experiment was conducted to investigate the effect of Butylated Hydroxy Anisole (BHA), Butylated Hydroxy Toluene (BHT), Pentoxifylline (PTX), Theophylline (TPY) and Theobromine (TBR) on cold protec...
In our previous report, we demonstrated that the tyrosine phosphorylation of sperm proteins (TPSP) of guinea pig was associated with capacitation and hyperactivation (CAHA), and Ca2+ and HCO3- were re...
Four experiments were conducted to study the following: i) the influence of different concentrations of sucrose (0.15, 0.3 and 0.5 M with osmolality of 308, 500 and 760 mOsm/kg, respectively) in dilue...
摘要采用直接注射的方法,将脂质体包裹的含人乳铁蛋白基因的重组质粒pLNCXHLF注入兔睾丸组织和羊输精管中,一个月后分别与正常雌兔及正常的母羊交配。所产仔兔均为活体,经PCR和Southern检测,转基因仔兔阳性率平均为35%(11/31);羔羊经引物F1/R1系统PCR检测阳性率为33.3%(4/12),F2/R2系统PCR检测阳性率为25%(3/12)。将流产羔羊组织解剖后提取舌、肺、肝脏、肌...
采用共培养和脂质体介导两种方法将金黄地鼠附睾内的精子与NFκB-luc+质粒共孵育后,再与成熟的卵母细胞进行体外受精,用PCR、Southern blot及荧光原位杂交(FISH)等技术检测外源基因在精子细胞和在受精卵中的存在及存在部位,并对相关数据进行统计学比较分析。结果表明,金黄地鼠附睾内的活精子具有主动捕获外源基因的能力,而且外源基因只存在于精子细胞的头部,而且通过受精将外源基因带入了卵细胞...
The present study was conducted to observe the effect of osmolality of glycerolated TEST-yolk glycerol extenders on post-thawing sperm kinematics of ram spermatozoa of the native Malpura breed maintai...
To evaluate the feasibility of using sperm-mediated gene transfer (SMGT) for carrying foreign gene into chicken oocyte, a reporter gene, CX-EGFP, was used in this study. The reporter gene was first mi...
