Epigenetics

Epigenetics the study of how cellular mechanisms control gene and how gene expression impacts health and behavior. Bi-directionality how human psychologically develop both by genetic predisposition and by the environment. Epigenesist does not change the genome, but the way cells react to the environment. Epigenome tell genome what to do. Epigenesist is controlled by methyl groups and histones. Methyl groups binds to a gene and tells it to not express it. Methyl groups bind differently to…

linear and one-directional. Epigenetic inheritance has shown that phenotypic behaviors and the environment are involved in gene expression and regulation, yet evolutionary psychology has done little to update its theoretical foundations in light of this (Racine, 2013, p. 144; Rosenberg, 2006, p.559). Therefore, attempts to integrate development into an evolutionary framework must theoretically accommodate bidirectional influences, while also practically answer epigenetic…

Pushing Boundaries of Human Enhancement through Cellular Reprogramming By definition, human nature is the different characteristics (thinking, attitude, feelings) created in ourselves by God. Many scholars and philosophers approach the concept of human nature by using different schools of thought. For instance, the Buddhists’ opinion about human nature is to be conscious and to aspire. Whereas Judeo-Christian’s point of view is that humans are God’s creation that has free willpower providing…

The epidemiology of depression shows that 20% of adults are either directly or indirectly impacted by depression during their lifetime, with twice the number women being diagnosed with the disorder when compared to men. Depression has also been shown to have a hereditary component, with a significant increase in diagnosis for individuals who have a family history of clinical depression. It is also reported that depression is highly correlated with suicide rates and physical disabilities such as…

Introduction: Embryonic stem (ES) cells are pluripotent cells that are derived from the inner cell mass of a blastocyst. These cells have the potential to differentiate into any of the 3 embryonic germ layers, and if cultured properly eventually can become any type of cell within the body. Due to the controversy and ethical concerns regarding the use of ES cells, scientists have discovered a way to generate pluripotent cells, by using Human Induced Pluripotent stem cells (hiPSC).…

How do Fat and Muscle Cells Change due to Exercise? Physical exercise has many health benefits: it reduces stress, as it causes the body to produce endorphins, which allows people to sleep better (1). In turn, sleeping better allows the brain to focus better on tasks it needs to perform. It prevents people from becoming overweight or obese, since it burns calories, and by preventing obesity, it in turn prevents heart diseases and diabetes (2). Many studies have shown that exercise changes how…

31. cis/trans isomers Isomers are compounds with a similar substance recipe however extraordinary structures. The structures of these isomers vary in the introduction of the two chloride particles around the Co3+ particle. In the trans isomer, the chlorides involve positions opposite each other in the octahedron. In the cis isomer, they possess contiguous positions. The distinction amongst cis and trans isomers can be recollected by taking note of that the prefix trans is utilized to portray…

Over the past week, we have 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 a myriad of reasons. It is incredibly interesting that the most important phases of prenatal development occur when some mothers are just discovering that they are pregnant. By the time a mother has realized she is pregnant the embryo’s brain, spinal cord, heart, and other organs have…

(CDK) and the dephosphorylation of retinoblastoma protein, which ultimately leads to cell cycle arrest in the G1 phase. Chidamide and Panobinostat are both newly approved drugs by the FDA. Chidamide acts to inhibit the growth of tumor cells by epigenetic regulation of HDACs, causing the regulation of the cell cycle and even apoptosis for patients with pancreatic cancer. Panobinostat, similarly, can act to arrest the cell cycle and also cause caspase dependent and independent apoptosis in…

There is a very well-known debate about whether sexual orientation is determined at birth. One side states that sexual orientation is a choice and you can choose to be heterosexual. The other side states that homosexuality is not something you can control and people are born gay. Both sides have valid points and statements and are free to believe what they wish. There are many factors that determine a person’s sexual orientation at birth: brain hemisphere dominance, hormones one receives during…
