elegans as a model organism to study the effects of P. granule localization and its application in human development to understanding the genetic influences behind psychiatric disorders, my major and research experience demonstrates my interests in developmental genetics and psychiatry. In addition, my experience working with a wide variety of patients from my exposure in the ED at the Mount Sinai Hospital and my interactions with inpatients at the 18N psychiatric unit and outpatients in Bellevue Hospital, demonstrates my clinical experience with patients. In addition, I have shadowed both ED doctors at the Mount Sinai hospital and have attended rounds in the 18N inpatient unit. My clinical experience demonstrates my passion for medicine, particularly psychiatry. My academic experiences not only help provide a background, and framework, in both biology and medicine, which will be useful in my future endeavors throughout medical school, but also provide me a better understanding of the practical applications of medicine and the work dynamics in a…

cells cease to be, and their union generates a new and distinct organism. This organism is a whole, though in the beginning developmentally immature, member of the human species. Readers need not take our word for this: They can consult any of the standard human-embryology texts, such as Moore and Persaud’s The Developing Human, Larsen’s Human Embryology, Carlson’s Human Embryology & Developmental Biology, and O’Rahilly and Mueller’s Human Embryology & Teratology. Human embryos, whether they are…

Many of the tasks that multi-cellular organisms perform are truly inspiring, from embryogenesis to organogenesis and other developmental processes. Developmental biology covers some of the most interesting procedures of the formation and transformation of living beings. One question in particular that sparked my interest in the vast field is how certain species of animals are able to completely reform a limb after it has been entirely severed. Such a feat is completely and utterly astonishing.…

genes that determine organ and limb formation during early embryonic development. Frances R. Goodman writes in Limb Malformations and the Human HOX Genes that humans have 39 HOX genes that are organized into four clusters that have their own roles in the development of the central nervous system, axial skeleton, genitalia, and limbs. HOX genes were first discovered through mutation in fruit flies, which led to further research with HOX genes in other vertebrates. The studies of HOX genes can…

Homeobox, also known as HOX genes, are genes that determine organ and limb formation during early embryonic development. Frances R. Goodman writes in his article “Limb Malformations and the Human HOX Genes” that humans have 39 HOX genes which are organized into four clusters. They have their own roles in the development of the central nervous system, axial skeleton, genitalia, and limbs. The study of HOX genes can lead to the identities of a number of human malformations. According to Shane C.…

Features of embryonic development in a chick and discussing Introduction During this essay, the features of embryonic development are analysed and comparisons between the developments of different species will be explored. Developmental biology is the study of the activity which leads to the growth and maturation of organisms.[1] The Red Jungle Fowl (Gallus gallus) is thought to be the ancestral to the modern domestic chicken. (Fumihito et al., 1994). [1] Chickens have had a long association…

From one cell to two-hundred different kinds of cells. Cell differentiation is the process of a cell changing from one cell type to another in developmental biology. In this process stem cells are used. A stem cell is a cell that has the ability to continuously divide and differentiate into various other kinds of cells or tissues. The process of differentiation results from the protein make-up of a cell. The blueprints for making these proteins are found in the nucleus of each cell as DNA; thus,…

Embryonic Stem Cell research (ESCR) evokes immediate controversy because of its intimate connection with human biomaterials. Ethical concerns for this type of research involve human dignity, personal privacy, and autonomy (Knapp). The Stanford Encyclopedia of Philosophy argues that there is a dilemma between the duties to alleviate human suffering and the preservation of potential life. While it is true that research on embryos involved in research become destroyed, the potential therapeutic use…

that can grow into an organism, (Seidel 1) and he had the idea to produce the grown embryo from the nucleus of an egg. When attempting to become successful, with cloning, the failure percentages are higher than the successes. The success rate is only at 1 to 4 percent for the clone attempt to be carried all the way out through birth (Kolata). Most cloned embryos will not withstand the duration of the pregnancy but if they do survive the development of the embryos could evolve abnormalities.…

As you wake up and hear the familiar cadence of the alarm, dread seeps into your deepest pores. Knowing you will suffer from intensified pain and less mobility than the previous day, you cringe at the harsh reality of your newly diagnosed condition. Yet the hope for a possible cure teases you daily, appearing more appetizing as each miserable moment passes. The desire to relieve your body from pain for even one day, no matter what the unknown the risks and long-term problems may be, is…
