Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes. Depending on the biological life cycle of the organism , gametogenesis occurs by meiotic division of diploid gametocytes into various gametes, or by mitosis.
In vitro fertilisation (IVF) is a process of fertilisation in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process , then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.
In vitro testing demonstrated that AOH1996 inhibited the growth and induced cell cycle arrest and apoptotic cell death in a wide variety of cancer cell lines, but had no effect on several normal, nonmalignant cell types. [6] [7] In mouse and dog animal models, there were no observed side effects or toxicity even at six times the effective dose. [3]
The primary disadvantage of in vitro experimental studies is that it may be challenging to extrapolate from the results of in vitro work back to the biology of the intact organism. Investigators doing in vitro work must be careful to avoid over-interpretation of their results, which can lead to erroneous conclusions about organismal and systems ...
AllTrials (sometimes called All Trials or AllTrials.net) is a project advocating that clinical research adopt the principles of open research.The project summarizes itself as "All trials registered, all results reported": that is, all clinical trials should be listed in a clinical trials registry, and their results should always be shared as open data.
A gamete (/ ˈ ɡ æ m iː t /; from Ancient Greek γαμετή (gametḗ) 'wife', ultimately from Ancient Greek γάμος (gámos) 'marriage') is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually. [1]
The Detroit Lions have taken away a fan's season tickets after he was involved in a verbal altercation with Green Bay Packers coach Matt LaFleur.
The Society for Assisted Reproductive Technology (SART) reported that in 2012 alone IVF resulted in about 61,740 babies born in the United States. The CDC estimates that IVF results in about 1 to 2 percent of births in the United States every year. [33] In 2016, IVF resulted in an estimated 76,930 live-born infants in the United States.
