  • Presence of epigenetic marks enables cells with the same genotype have potential to display different phenotypes and differentiate into many cell-types with different functions, and responses to environmental and intercellular signaling. For example, DNA methylation is essential for the process of imprinting. Imprinted genes are expressed from only one parental allele. This mono-allelic gene expression is directed by epigenetic marks established in the mammalian germ line and a single mutation, either genetic or epigenetic, can cause disease.

  • Ooplasmic transfer involves egg retrieval from the woman undergoing IVF and another woman donating ooplasm (the cytoplasm of an egg cell: the material outside the nucleus). The egg is then fertilized with sperm and implanted into the woman intending to become pregnant. The resulting child has DNA from both women because of the mitochondrial DNA present in the ooplasm of the donor, as well as DNA from the sperm provider (partner or donor), and therefore has three genetic parents. It had been used for women whose infertility seemed to stem from the ooplasm in their eggs.

  • Surrogacy is an agreement in which a woman becomes pregnant and gives birth to a child for someone else. Surrogacy can be paid or unpaid, and often involves a legal contract in which the surrogate gives up parental rights to the child she births. If the surrogate’s own eggs are used through alternative insemination or IVF, she is known as the “genetic surrogate.” If embryos are created using another woman’s eggs and implanted in the surrogate, she is known as the “gestational surrogate” and has no genetic tie to the child. Hiring a surrogate in the US can...

  • Naturally, during the years I’m considering,American films have changed enormously.They have become sexier,more profane, and more violent; fart jokes and kung fu are everywhere. The industry has metamorphosed into a corporate behemoth, while new technologies have transformed produc- tion and exhibition. And, to come to my central concern, over the same decades some novel strategies of plot and style have risen to prominence. Behind these strategies, however, stand principles that are firmly rooted in the history of studio moviemaking.

  • In 1990, preimplantation genetic diagnosis (PGD) was introduced as an experimental procedure to genetically screen human embryos during an in vitro fertilization (IVF) cycle (1,2). More than a decade later, PGD has become an established clinical procedure in assisted reproductive technologies with over 6500 PGD cycles performed worldwide, resulting in the birth of well over 1000 healthy babies and a pregnancy rate per transfer of approximately 24% (3).
