physiological phenomenon, which prevents congenitally malformed or chromosomally abnormal embryos to progress to viability. Congenital and/or chromosomal abnormalities incompatible with life observed in 85% of early clinical miscarriages.[5] However, some aneuploidies can survive to term pregnancy as trisomy 21. The fetal chromosomal abnormalities of maternal origin are related to the advanced maternal age and caused during the first meiotic division. In addition; chromosomal aberrations are…

blood is analysed to detect aneuploidies (in particular trisomy 21). The breakdown of fetal and placental cells results in cffDNA which is then cleared from the mother within a few hours, therefore it can be analysed to detect chromosome defects for the current foetus. Currently in the UK, NIPT is offered by the NHS to high risk pregnant women for a number of conditions, approved by the UK Genetic Testing Network. Women at high risk can include; family history of aneuploidy, advanced maternal…

Toxic substances come in all shapes and forms. Often they have varying visible outward effects, but often enough the damage and problems lie under the surface. The Endocrine System is the chemical communication system between cells. Special glands secrete chemicals which travel throughout our body and bind to complimentary receptors (Barnes, 2014). These chemicals, or hormones, are responsible for regulating growth, behavior and many more aspects of our bodies and behavior. In recent times…

Ashley is a 26yo, G4 P2012, who is currently 35 weeks 3 days as dated by an 8-week ultrasound. She is relatively healthy. She has 2 prior cesarean deliveries and is planning a repeat. She declined any aneuploidy testing. She had a recent scan for growth and there was concern for non-visualization of the cavum septum pellucidum. She was referred for further consultation. Of note, the CSP was called normal at the time of the anatomy scan at 21 weeks. On ultrasound, there is a live fetus in…

possibly understand the genetic basis of some of these features or defects and can slowly learn how to prevent, ameoliorate, and eliminate their treatment. These maps also help provide the basis for clinical prognosis for people who have partial aneuploidy for chromosome 21, and also…

An omphalocele is a birth defect in which abdominal organs, primarily the intestines, herniate out of the body through a hole in the navel. Omphaloceles vary in size from containing only a portion of the small intestine to a majority of the abdominal organs, including most of the liver. This latter scenario, which includes about a third of omphalocele cases, is referred to as a giant omphalocele and can involve complications due to a small abdominal cavity and underdeveloped lungs.…

The dots can then be counted to identify the embryos that contain translocation or aneuploidy and only healthy embryos will be used (PGD). A disadvantage of using the FISH technique is that only 10 to 12 chromosomes can be analyzed at a time, while a human cell contains 46 chromosomes. This lessens the chances of transferring a healthy embryo…

In Vitro Fertilization (IVF), is a reproductive technology involving an egg being removed from a woman, and joined with the sperm cell from a man. This process all happens in a test tube, for the intent of controlling those who suffer from problems with fertility (Pbs.org, n.d.). The cells then join together in a process called meiosis, where they then divide to form an embryo. IVF is most commonly used for those who would otherwise be unable to have children, including blocked tubes, same sex…

transformation increase, the resistance to the potion decreases, and eventually the threshold that keeps Mr. Hyde at bay is weakened and now a flood gate. According to Dr. Pavelka, there is thousands of corresponding DNA and mRNA sequences, many reasons for aneuploidy. Unique combination calls for certain actions, whether it’s the produce eggs cells or hair cells. Cancer production is brought upon by certain sequences, similar to how Mr. Hyde is brought about through the potion. This certain…
