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 ...
Testicular Characteristics and the Block to Spermatogenesis in Mature Hinny
Hinny Testis Seminiferous Tubule Spermatogenesis Defect Sterility
2016/7/27
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...
Seasonal variation of isoprene basal emission in mature Quercus crispula trees under experimental warming of roots and branches
isoprene biogenic volatile emission Quercus crispula experimental warming
2017/4/11
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...
Growth of Ovarian Primary Follicles Retrieved from Neonates of Different Ages and Derivation of Mature Oocytes Following In vitro-Culture
Neonatal Mouse Ovary Primary Follicle In vitro Culture Oocyte Maturation
2016/5/10
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...
A mature cluster with X-ray emission at z=2.07
Galaxies clusters:general – Galaxies:clusters individual:CL J1449-0856 – Galaxies high-redshift large-scale structure of the Universe
2010/11/12
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...
A Mature Dusty Star-forming Galaxy Hosting GRB080607 at z=3.036
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
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...
Snowpack Chemistry During Snow Accumulation and Melt in Mature Subalpine Forest and Regenerating Clear-Cut in the Southern Interior of B.C.
Snowpack Chemistry Snow Accumulation Mature Subalpine Forest
2009/10/23
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...

Cadmium compounds (cadmium para hydroxybenzoate cadmium chloride) kupffer cells liver and mouse
2010/3/25
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...
孔雀活化素基因(activin)ßA 亚基成熟肽序列的分子克隆及其对白孔雀起源与分类的佐证分析Molecular Cloning of Activin ßA Subunit Mature Peptide from Peafowl and Its Application in Taxonomy and Phylogeny
孔雀 活化素基因 系统发生 分类 peafowl activin gene phylogeny taxonomy
2007/12/5
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...
