Using this procedure, healthy mitochondria from a third party can be donated in the fertilization process to create a healthy child from three genetic “parents.” There is much concern about the safety and ethics of this procedure and presenting the Catholic and Jewish perspectives of Mitochondrial Replacement Therapy can offer insights into the morally complexity of the ethical issues surrounding this innovative medical procedure.

Recent experiments explore the use of clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 for germline engineering in the embryo, which alters future generations. The embryo's inability to express an autonomous decision is an obvious bioethical challenge of germline engineering. The philosopher Joel Feinberg acknowledged that autonomy is developing in children. He advocated that to reserve this future autonomy, parents should be guided to make ethical decisions that provide children with open futures. Here, Feinberg's 1980 open future theory is extended to the human embryo in the context of CRISPR germline engineering. Although the embryo does not possess the autonomous decisionmaking capacity at the time of germline engineering, the parental decision to permanently change the unique genetic fabric of the embryo and subsequent generations disregards future autonomy. Therefore, germline engineering in many instances is objectionable considering Feinberg's open future theory.

Podophyllotoxin inhibits microtubule assembly in vitro while VP-16-213 has no effect in this system. VP-16-213 induces single-stranded breaks in DNA in HeLa cells, an effect which may explain the cytoxicity of VP-16-213. In contrast to VP-16-213-treated cells, cells treated with podophyllotoxin maintain DNA integrity and show no evidence of single-stranded breaks.

The calcium channel blockers verapamil, nifedipine, and diltiazem had no effect on c-fos induction. In rat heart, c-fos expression was also stimulated by the alpha-adrenergic agonist phenylephrine, histamine, and prostaglandin E 1. The Hl-receptor antagonist pyrilamine, but not the H2-receptor antagonists ranitidine and cimetidine, blocked the histamine-induced expression ofc-fos. We conclude that in the heart, hormones which increase cAMP and cytosolic Ca 2+, such as beta-adrenergic agonists and prostaglandin El, and/or stimulate the turnover of phosphatidylinositides, such as alpha-adrenergic agonists and histamine Hl-receptor agonists, regulate c-fos gene expression. It is suggested that fos protein plays a role in the mechanisms of neurotransmitters and hormones that modulate the functioning of the heart and possibly in cardiac hypertrophy, degeneration, and necrosis.

The lignans are characterized by their dimeric composition from cinnamic acids, and they are attracting increasing attention as a result of their pharmacological properties. The volume surveys the chemical, biological and clinical properties of lignans as well as providing information on their isolation, purification, identification and chemical synthesis. The volume also explores fully the potential use of these compounds as antiviral and antitumour agents, and thus provides a wide-ranging survey of their pharmacology and chemistry. The text is fully documented and referenced and provides the only up-to-date compilation on this subject. The volume is suitable for research scientists in the fields of organic chemistry, biochemistry, oncology, pharmacology, toxicology and botany.

According to the latest assessment by the Center for Disease Control, the rate of women between the ages of 15 and 44 who suffer from some form of impaired fecundity (a physical inability to have a child) is almost 12% (approximately 7.5 million). 1,2 In the Jewish community, estimates of infertility are as high as one in six women. 3 To reduce infertility, biotechnologies and medical innovations have been, and are currently being, developed to allow men and women to have children in ways that have never been previously considered possible. In fact, the last forty years have been transformational in reproduction medicine by providing a wide variety of new drugs, procedures (such as artificial insemination, in vitro fertilization, hormonal treatments) and surgical interventions to treat infertility in women. 4 Current interventions include 1
