This study was designed to determine if the addition of androgens at ovarian follicular fluid (FF) concentrations to oocyte maturation media would alter the development and sex ratio of bovine embryos.
This unique dataset provides an opportunity to examine the strength of reproductive isolation, the development and sex ratios of hybrid offspring, patterns of fertility and infertility, and polyploidization in hybrids all in the context of genetic divergence between parental species.
Nanomolar concentrations of steroid hormones such as 17β-estradiol can influence the reproductive development and sex ratios of invertebrate and vertebrate populations.
With regards T cell development, analysis of the numbers and ratios of T cell subsets in thymus and peripheral lymphoid organs showed that this was also normal in triple-mutant mice (Figure 5).
In order to investigate a potential role for PTPN4 in immune cell development, we examined the numbers and ratios of leukocytes in primary and secondary lymphoid organs of PTPN4-deficient mice by flow cytometry (Figure 2A).
The levels of ACh- and GABA-mediated neurotransmission and the activity of voltage-dependent sodium channels are critical throughout prenatal and postnatal development, defining the ratio of excitatory and inhibitory neurotransmission in the brain, but also promoting and refining neural networks in the developing and adult brain (Belmonte and Bourgeron 2006).
Real per capita GDP was used as a proxy of economic development while ratio of domestic credit to GDP, total capital formation to GDP, weighted average savings interest rate minus current GDP deflator and GDP deflator were used for financial development.
Cronos is expressed at high levels in zebrafish skeletal muscle during development (∼2:1 ratio of Cronos to full-length ttna), but drops off sharply during adulthood (∼1 70 ratio).
Our primary observation is that Cronos expression is at high levels in zebrafish skeletal muscle during development (∼2:1 ratio of Cronos to full-length ttna), but drops off dramatically during adulthood (∼1 70 ratio).
Today, city planners are preparing a rezoning of several blocks immediately north of Canal Street, including Mr. Vendome's site, to permit residential and commercial development with a ratio of 6.
