The Role of microRNAs in the Regulation of Apoptosis
Words • 528
Pages • 2
miRNA in cancer: apoptosis which is also known as programmed cell death is very important in animal’s development and disease. However, any dysregulation in apoptosis can lead to various neoplastic processes (NEOPLASIA is the abnormal growth and proliferation of abnormal cells or abnormal amount of cells due to a benign or malignant process). ApoptomiRs is the miRNA that regulates the apoptosis and this can be proapoptotic (that leads to apoptosis) or antiapoptotic. Drosophila gene banatam are the first miRNA that…...

Each year thousands in the U. S. experience damage to the nerve bundles that carry messages from the brain to the rest of the body.

Ketones are versatile compounds which can be transformed to a variety of helpful functional groups through decrease, nucleophilic addition or condensation reactions. Ketones and aldehydes are necessary series in preparation of other compounds and they are frequently prepared by oxidizing alcohol which is performed in this experiment. Ketone also plays an extremely crucial part in natural synthesis. Ketones and aldehydes can be synthesised into numerous other chemicals. Responses involving ketones include nucleophilic addition responses to the carbon-oxygen double bond to…...

Comparison Cell Death of Necrosis and Apoptosis
Words • 451
Pages • 2
Both necrosis and apoptosis are the two types of cell death than can occur when a cell has undergone harm or disease. Necrosis is an uncontrolled process in which there is a complete breakdown of cellular homeostatis with a large unco-ordinates breakdown of all cellular constituents. Necrosis can occur due to many factors such as an infection or failure of blood supply (ischemia). Examples of necrosis can includes Fat necrosis (seen in patients with breast cancer), Caseous necrosis and coagulation…...
Apoptosis – Short Essay
Words • 2906
Pages • 11
Kerr, Wyllie, and Currie first used the term apoptosis in a paper in 1972 to describe a morphologically distinct form of cell death, although certain components of the apoptosis concept had been described years previously. Our understanding of the mechanisms involved in the process of apoptosis in mammalian cells transpired from the investigation of programmed cell death that occurs during the development of the nematode Caenorhabditis elegans (Horvitz, 1999). In this organism 1090 somatic cells are generated in the formation…...
Definition Essay Altruism

Eric Gibson, the editor of the Leisure & Arts page of The Wall Street Journal, once wrote that “Anonymity is the truest expression of altruism.” I do agree with this statement but, from my point of view, altruism is much more than that. It is to help a stranger in need even at the expense of your own well-being. A true act of greatness! Altruism, unfortunately, can neither be learnt nor taught, but rather stems directly from the individual’s heart.…...
