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. ...
Throughout nature, moms engage in a trade-off: Churn out a bevy of offspring and hope for the best, or have fewer kids but invest more in their survival.Trinidadian guppies provide a model example of ...
Most hinnies (female donkey×male horse) and mules (female horse×male donkey) are sterile with few reports of equine fertile hybrids. The main cause of this sterility is thought to be a meiotic block t...
Isoprene is a reactive volatile organic compound (VOC), the annual global biogenic emissions of which are the largest of the non-methane VOC. Since isoprene emissions are partly temperature-driven, u...
This study was conducted to improve the yield of mature oocytes from in vitro-culture of ovarian primary follicles by optimizing follicle retrieval from neonatal mice of different ages. Primary follic...
We report evidence for a fully established galaxy cluster at z = 2.07, consisting in a ∼ 20σ overdensity of red, compact spheroidal galaxies which spatially coincides with an extended X-ray emis...
We report the discovery of the host galaxy of dark burst GRB080607 at z_GRB=3.036. GRB080607 is a unique case of a highly extinguished (A_V~3 mag) afterglow that was yet sufficiently bright for high-q...
Chemical profiles in snowpacks were observed during snow accumulation and melt periods at subalpine sites in the southern interior of British Columbia. During accumulation periods, concentrations of...
In this study, 4 experimental groups and 1 control group containing adult mice (Mus musculus var. albinos) were used to examine the effects of 2 different cadmium compounds, namely cadmium para hydrox...
摘要参考已经克隆的活化素(activin)基因βA亚基成熟肽序列,设计一对兼并引物,从绿孔雀(pavo muticus)、蓝孔雀(pavo cristatus)和白孔雀基因组中克隆到活化素基因βA亚基成熟肽序列。测序结果表明,活化素基因βA亚基成熟肽序列长345bp,编码115个氨基酸。序列分析表明,蓝孔雀与绿孔雀核苷酸同源性为98.0%,而蓝孔雀与白孔雀核苷酸同源性为98.8%。NCBI收索结果...

Myostatin is a member of the transforming growth factor-??(TGF-?? super-family. It acts as a negative regulator for skeletal muscle growth. Myostatin mutations are characterized by a visible, generali...
The objective of this study was to evaluate the net flux response of nitrogen compounds (alpha-amino N, ammonia N, urea N, essential amino acids) across the portal-drained viscera (PDV), liver and tot...
Six mature purebred Angus cows (3.5 1.5 years of age, 631.36 8.63 kg), three pregnant (250 7 days pregnant) and three non-pregnant and eight mature Suffolk ewes (5 1.2 years of age, 68.18 2.3 kg) four...
