Epigenetics

cells that were unable to be removed in surgery (4). One of the specific drugs that Jordan was prescribed was temozolomide, which is meant to damage actively dividing cells. This drug has varied affects on patients and is dependent on the patient’s epigenetics. The survival rates for patients with this treatment were reported to be a median survival of 14.6 months and a two-year survival rate of 30% (3). Specifically, the methylation or lack of methylation of the MGMT gene can have an extreme…

I was first introduced to the Human Genome project in 2000, where my molecular biology professor explained genes as small units of DNA in a sea of genetic gibberish or junk. The concept of “junk DNA”was very intriguing to me that why nature created those billions of nucleotides of DNA inside a cell, organized it and packed it without any purpose? Soon I started following the thoughts of Francis Crick, Nobel laureate and co-discoverer of DNA double-helix, who in the early 1960s professed his…

I.A Background & Key Question(s) Rapid reproductions in muscles cells are needed because our muscles are constantly exposed to exercise and injury. In our muscles, Myoblast is the embryonic cells that mature and fuse together forming Myocytes. Through the process myogenesis, Myocytes form muscles. However, specifically satellite cells aid in new growth and regenerated muscle. Since these cells respond to one another and create a domino effect they were used in this experiment. Rozwadowska et al…

AETIOLOGY OF ALLERGIC RHINITIS Genetic predisposition Genetic predisposition is a major factor in the aetiology of AR. The clinical evidence include: the fact that a family history of allergic rhinitis is often present and the association of Allergic rhinitis with other atopic diseases that possess a genetic basis, such as allergic asthma or atopic dermatitis. It has been reported that Allergic Rhinitis has a hereditary component but does not exhibit a Mendelian hereditary pattern. The…

To deny free will outright and place all of the blame on genetics is irrational as it would completely ignore the significant findings of epigenetics. Contrastingly, to deny the effect our genes have on our actions is to be willfully ignorant of scientific data. Thus, I feel that both play an equally important role in the way that humans behave. However, I do lean more in the direction that…

Discussion: It is my belief that BCI research to effect cognition, memory and thought is just an extension of work that aims to effect change in the brain. From psychotherapy to pharmacological intervention, research has focused for a long time on assisting patients in need with altering their mental state, particularly for diagnoses such as depression, bi-polar disorder, schizophrenia and other debilitating diseases. Patients with minimal use of their limbs or with neurodegenerative diseases…

Erikson’s epigenetic principle is similar to the process of the unfolding of a rose bud, each petal opens up at a certain time, in a certain order, that is predetermined. If we interfere in the natural order of development by pulling a petal forward prematurely or out…

Literature Review Kristen Allen Hodges University PSY-3550 Professor Bushey 04/12/2015 Review of the Literature Awareness and interests within substance abuse has come to a major forefront in the last several decades, but more than ever in episodic events within the scope of opioids and opiates. The review focuses on the aspects of substance use disorders, chronic relapsing disorders, behaviors, scientific studies of the brain and how substances effect individuals genetic…

Introduction DNA makes up the genetic material for all organisms. However, not all organisms have distinct molecules working with DNA that come together to make up chromatin. Chromatin is only found in eukaryotic cells, the cellular makeup of multicellular organisms. The structure of chromatin is composed of DNA and histones, together making up nucleosomes, and other non-histone proteins that bind to the DNA. The backbone of DNA is negatively charged and histones have a positive charge…

This past week we discussed prenatal development. Although prenatal development is not an area that directly relates to the work of a child life specialist, I am personally interested in this topic for various reasons. I find it incredibly interesting that the most important phases of prenatal development occur when most mothers are just discovering that they are pregnant. I am intrigued by this topic because it is truly amazing what human bodies can do and create through such a defined…
