The Riddle Of The Fetal Allograft, Rachel Tepper Jan 2021

The Riddle Of The Fetal Allograft, Rachel Tepper

The Science Journal of the Lander College of Arts and Sciences

The immunological paradox of nurturing a fetus with paternal antigens poses some perplexing questions. Peter Medawar, an immunologist, asked at a lecture, “How does the pregnant mother contrive to nourish within itself, for many weeks or months, a fetus that is an antigenically foreign body?” Researchers have since then struggled to answer this question. The research on this topic has led to a few general hypotheses that try to explain this phenomenon. The downregulation of T cells toward paternal alloantigens is an accepted hypothesis. Another hypothesis discusses the significance of the decidua and its ability to impair dendritic cells, which …


Does Preimplantation Genetic Testing Increase The Risk Of Adverse Clinical Outcomes?, Robyn Weiss Jan 2020

Does Preimplantation Genetic Testing Increase The Risk Of Adverse Clinical Outcomes?, Robyn Weiss

The Science Journal of the Lander College of Arts and Sciences

Before 1990, options were limited for couples who were at risk for transmitting a genetic disease or a structural chromosomal abnormality to their children. Couples traditionally underwent invasive procedures such as amniocentesis and chorionic villus sampling, after which termination was offered if the fetus was found to be affected. Many couples chose not to have children at all. Since then, technological advances have allowed preimplantation genetic testing (PGT) to be offered to these couples. Couples who choose PGT undergo in-vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI), where the oocyte is injected by a single sperm and is then implanted …

The Effects Of Maternal Caffeine Intake On A Fetus, Jennifer Kahan Jan 2018

The Effects Of Maternal Caffeine Intake On A Fetus, Jennifer Kahan

The Science Journal of the Lander College of Arts and Sciences

The United States has been noted as the country with the greatest caffeine consumption in the world. More than half of all Americans are said to consume caffeine on a daily basis. Caffeine is easily available in a variety of dietary products including coffee, tea, soft drinks, and chocolate. Many pregnant women are unaware of the potential risk that excessive caffeine consumption can have on their unborn child. The purpose of this paper is to explore the ramifications of caffeine intake on a fetus. The studies reviewed propose that heavy maternal caffeine consumption, that of more than 300 mg daily, …


Gestational Diabetes And Its Effects On The Fetus, Todd Pollack Jan 2009

Gestational Diabetes And Its Effects On The Fetus, Todd Pollack

The Science Journal of the Lander College of Arts and Sciences

Although the common effects of gestational diabetes on the fetus are known, the outcome of a diabetic gestation is ambiguous. There is concern for complications in the fetus at delivery due to enlarged size of the fetus, as well as concerns for birth defects, fetal distress, diabetes and obesity. Yet, although there is a correlation in the previous disorders and gestational diabetes, many of the mechanisms that cause these complications are unknown. By studying the pathology of gestational diabetes, researchers have learnt that the placenta controls fetal growth and provides a great deal of protection for the fetus. Therefore, many …
