I am going to write my article on something that we all must face if we are fortunate to do so: Aging. What I am looking for is the history of ways people have gone to reach the fountain of youth. I will also research about the aging process. These things will be for a natural lifetime. What I am also interested in when it comes to aging, is future technologies that are to be introduced and experimentations on lengthening the life span, and reducing the physical ailments of aging. For those…

The nucleolus which is also known as the brain of a cell, is the most significant part in the nucleus. It takes up about 25 percent of the nucleus and it is not surrounded by a membrane. Through a microscope, the nucleolus is a big dot in the middle of it. It can be found in an animal, plant, diploid, and eukaryotic cell. It was found in the eighteenth century but its function wasn’t discovered until the 1960s. The nucleolus lives in the nuclear matrix. Sadly, the nucleolus is one of the…

BRCA1 and BRCA2 genetic testing, should everyone do it? Shahrzad Eslamian Purpose: For a person with a positive mutation in BRCA1 or BRCA2, the chance of getting breast cancer increases by 50-60 percent.1 This causes concern for some women and makes them take a BRCA1/2 mutation test to make sure they are not carrying this mutation. In September 2015, a research from UCLA was published that indicated some debate over whether or not testing BRCA genes is worth the cost.4 This paper will be…

With the advancement of medicine and improvement in the quality of life is leading to an increase in the group of older people in our society. The majority of the elder people around 60 to 70 % are independent, 30% are classified as fragile or at risk, and only 3% are adults greater bedridden or disabled. As we exceed 65 there is an increase in the probability that functionality of humans will start showing its limitation. Before discussing the characteristics of the aging process, and the main…

79-110 million people are currently infected and the worldwide risk of HPV infection at least once in their lifetime in both men and women is 50% (Handler et al., 2015). The risk of being infected with HPV is 24% after someone becomes sexually active if they are also under 25 years old (Foreman et al., 2012). Worldwide, cervical cancer is the 3rd most commonly diagnosed cancer and is the fourth most common cause of cancer death in women with a higher mortality rate in developing nations (Handler…

I am motivated to pursue a career in medicine as a result of my work experience in a hospital which I thoroughly enjoyed. I am fully aware that a high level of stamina, enthusiasm and understanding of the needs both physical and emotional of a patient whilst using a non-judgemental approach are all essential. I observed the intellectual demands that come with the job and feel that I have the personal attributes to cope with these demands. In knowing my limitations I feel I will be able to cope…

Hypothalamic programming of systemic ageing involving IKK-b, NF-kB and GnRH (Zhang et al., 2013). Cellular senescence is when a cell’s replicative mechanism becomes arrested. This was phenomenon was first described in Hayflick’s experiment. Cellular senescence is usually due to protect the cell from becoming cancerous but it also plays a prominent role in aging (van Deursen, 2014). While senescence describes a halt in proliferation, cancer development is the uncontrolled proliferation of…
