discovery of antibiotics, each medical breakthrough highlighted the success of humans in dealing with the prevailing medical issues of that time. With the discovery of the structure of DNA by Crick and Watson in the early 1950s, the focus on medical research has shifted to the understanding of the genetic cause of a particular disease. Because of this, we are now able to understand the pathophysiology behind much of the diseases that has been a mystery to us before. An example of this is cancer, which

have billions of cells. The nucleus of such a cell has genetic information called DNA. All the nuclei of an animal have the same information. But each cell only uses a part of this information in order to work properly. The other part of the DNA is not active. But because a single cell holds all the DNA of an animal, scientists can make physical copies of an animal from only one cell. They transfer the nucleus of an animal’s cell into an egg cell of another animal. This egg cell has the same genetic

Adrenoleukodystophy (ALD) Understanding an Animal Cell: Basic Units of Life The cell is the fundament unit of life. They make up the smallest level of a living organism in the human body, where the metabolic processes happen to in order to maintain life. It itself is considered a mini-organism made up from organs called organelles. These organelles are the structural and functional units and are created from several macromolecules connected together. A typical animal cell contains the following organelles (Tracey

cerebellum, the meninges, and the brain stem. The cells which make up the brain are the nerve cells and the glial cells (Srinivasan, et al., 2011). Any abnormal cell division in any of the brain parts can lead to brain cancer that can be of various types. The actual causes of brain cancers are still unknown; thus, there are many diagnosis and treatments of the disease that in their turn need improvement. Brain cancer can be defined as the condition when certain brain cells divide uncontrollably and spread

Abstract: Sickle cell anemia is an important world health problem that involves the genetic of our body where an an approximate of about 300,000 infants are born per year in the world, thereby posing it as an important factor for parenthood where it can easily be avoided. Acute, chronic, and acute-on-chronic complications contribute to end-organ damage and adversely affect the quality of life. (ncbi.nlm.nih.gov/pubmed2017) This article describes this disease it's vaso-occlusive crisis that occur

“What does impact mean to you?” My entrepreneurship professor asked us to define the term in a way that related to our personal goals. A few examples of impact that immediately popped into my head included Embrace Innovation, whose low-cost incubator saved 300,000 babies across 22 countries and Doug Rouch’s Daily Table, which sells fresh, low-cost produce to some of the 49 million Americans struggling with hunger. How did their journeys relate to my aspiring career in dentistry? I recalled shadowing

Sickle cell anemia(SCD) is an inherited genetic disorder which causes the expression of defective hemoglobin on chromosome 11 resulting irregularly shaped red blood cells also known as “sickle cells” because they look like a sickle or are in a crescent shape. The normal red blood cells are round, smooth and deliver oxygen to cells throughout the body but a cluster of sickle shaped cells blocks the blood flow, causing painful attacks and sometimes stroke. Due to their different shape and chemistry

site of injury and stimulates the growth of stem cells there. Brain injuries are particularly hard to repair, since injured tissues swell up and can cause additional damage to the cells. So far, treatments have tried to limit this secondary damage by lowering the temperature or relieving the pressure at the site of injury. However, these techniques are often not very effective. More recently, scientists have considered transplanting donor brain cells into the wound to repair damaged tissue. This

The disease I have chosen to research is Severe Combined Immunodeficiency. I am interested in the disease because not a lot of people know about this disease. It’s a very rare disease. Severe Combined Immunodeficiency has an acronym. It is SCID. Some of the questions I have about the disease are: Is this disease treatable? If you can help it from happening or cause it from happening?, How common is it? Find out what it does to your body? What are the symptoms? Hopefully the information I obtain

involved in the cloning method by describing the terminating of embryos. The author reaches out to the general concerned public with this article in order to give them knowledge on the subject. Cloning is a highly disputed topic that is still in the research process. In truth cloning is a very interesting subject and could possibly prove beneficial someday. However, I completely disagree with supporters on the morality of the issue. Cloning does peak my interest in such ways as the thought process of
