The Effect of Nonsteroidal Anti-Inflammatory Drugs on Chick Embryo Fibroblast Cells and Its Relation to Colon Carcinogenesis
The Effect of Nonsteroidal anti-inflammatory drugs on chick embryo fibroblast cells and its relation to colon carcinogenesis Abstract NSAID's are chemopreventive mediators of colon carcinogenesis, although their molecular pathway is unknown. Previous studies suggest that NSAID's best known effect is its inhibition of prostaglandin, a lipid that is derived from fatty acids. To study the effect of NSAID's on chick fibroblast cells, we sought to apply aspirin (a common NSAID) to these cells in

Whether or Not Cell Phones Should Be Allowed on School Campus
Whether or not cell phones should be allowed on school campus Many children today own a cell phone and usually bring it to school. However, a plethora of people who work at the school don’t like the idea of having cell phones on school campus for countless of reasons. So now there is this big controversy on whether or not cell phones should be allowed on campus. In spite of this I believe that children

Sickle Cell Anemia
Sickle Cell anemia is a group of inherited red blood cell disorders, or a collection of recessive genetic disorders characterized by a hemoglobin variant called Hb S. Normal red blood cells are round like doughnuts, and they move through small blood tubes in the body to deliver oxygen. Sickle red blood cells become hard, sticky and shaped like sickles used to cut wheat. When these hard and pointed red cells go through the small

Stem Cell Essay
One of the greatest issues in the world today is the threat of neurodegenerative diseases. These diseases are responsible for about 60,000 deaths per year, many of which are preceded by up to several years of excruciating pain and suffering. These, among other health issues such as heart disease, arthritis, and diabetes, are treatable with stem cell therapy. With the myriad of diseases treatable with stem cell technology, it is surprising that more effort is

Sickle Cell Anemia
Sickle cell anemia is a hereditary disorder that mostly affects people of African ancestry, but also occurs in other ethnic groups, including people who are of Mediterranean and Middle Eastern descent. More than 70,000 Americans have sickle cell anemia. And about 2 million Americans - and one in 12 African Americans - have sickle cell trait (this means they carry one gene for the disease, but do not have the disease itself). Sickle cell anemia

Alternative Fuels
As humans continually exploit the earth for their own conveniences they become increasingly aware of the damage they cause. In the last 30 years the population has begun to notice just how serious the problem is and as a result great efforts have been put into amending the environment from our technological follies. Since the use of fossil fuels causes 70% of the earth's air pollution it's only logical that the human race must

Regulate Use of Cell Phones on the Road
When a cell phone goes off in a classroom or at a concert, people are irritated, but at least lives are not endangered. When on the road, however, irresponsible cell phone users are more than irritating: They are putting our lives at risk. Many of us have witnessed drivers so distracted by dialing and chatting that they resemble drunk drivers, weaving between lanes, for example, or nearly running down pedestrians in crosswalks. A number

Stem Cell
Many people have not been fully informed on the topic of human pluripotent stem cell research. Most American have heard a lot on one side, and very little on the other. Hence, they have not and can not fully evaluate the facts and can only give snap decisions, according to religioustolerance.com. Having heard extensive lectures on both sides, I believe that embryonic stem cell research shows great promise in bettering the medical and scientific community.

Stem Cells
Stem cells show potential for many different areas of health and medical research, and studying them can help us understand how they transform into the dazzling array of specialized cells that make us what we are. Some of the most serious medical conditions, such as cancer and birth defects, are caused by problems that occur somewhere in this process. A better understanding of normal cell development will allow us to understand and perhaps correct the

The Cell as the Basic Unit of Life
Like cement sets the foundation for a house, the cell theory sets the foundation for biology. Schleiden and Schwann proposed the cell theory, which states that the cell is the basic unit of life and that new cells arise only from the reproduction of already existing cells via cell cycle, in 1839. Since the cell is the structural and functional unit of life as the house is for a community, without the house the community

Alternative Fuel Vehicles Comparison
Alternative Fuel Vehicles comparison Electric Early automobiles were electric, having electric motors powered by batteries. But their range was limited, and internal combustion engines were more powerful, at a time when there were not concerns about the supply of fuel, or the emissions. But, the recent focus on air quality and the advances in the battery technology have made the electric vehicle a viable alternative. Electric drive systems are virtually pollution free, (in fact, they

Sickle Cell Anemia
Sickle Cell Anemia Sickle cell anemia is an inherited blood disorder, characterized primarily by chronic anemia and periodic episodes of pain. The underlying problem involves hemoglobin, a component of the red cells in the blood. The hemoglobin molecules in each red blood cell carry oxygen from the lungs to the body organs and tissues and bring back carbon dioxide to the lungs. In sickle cell anemia, the hemoglobin is defective. After the hemoglobin molecules give

Drug Resistance Mechanisms in Cancer Cells
INTRODUCTION A major obstacle in the successful treatment of cancer is the development of resistance mechanisms to drug treatment. Various cellular changes that have been implicated in the development of drug resistance in cancer cells include: the increased expressions of P-glycoprotein (a multidrug transport protein) and multidrug resistance-associated protein (MRP-1); increased levels of the cellular detoxification protein, glutathione; and changes in the expression of apoptosis associated proteins such as Bcl-2, FasL and p53, which generally

Embryonic and Adult Stem Cells
Stem cells relate to the person health of an individual. Stem cells have the remarkable ability to develop into many different cell types in the body. Able to be a repair system for the body, they can divide without limit to replenish other cells as long as the person alive and able to provide nutrients to the cells. When a stem cell divides, each new cell has the potential to either remain a stem

Embryonic Stem-Cell Research
Embryonic stem-cell research is a big issue today. Embryonic stem-cell research destroys the stem cells of early embryos to create any cell in the human body like a bone marrow. It all started in the mid 1800s when scientists discovered that some cells could generate other cells. In 1994, President Clinton prohibited federal funding on research to support the creation human embryos for research purposes. Federal laws were put in place to prohibit the Department

Stem Cell Research
Stem cellular structures are cells found in most multi-cellular organisms. They are capable of retaining the ability to reinvigorate themselves through mitotic cell division and can differentiate into a diverse range of specialized cell types. Research in the stem cell field grew out of findings by Canadian scientists Ernest A. McCulloch and James E. Till in the 1960s.[1][2] The two broad types of mammalian stem cells are: embryonic stem cells that are found in blastocysts,

Stem Cell Research
Stem cell research has been a controversial topic since its birth. Of course, anything that uses an embryo would be. With a topic like this, anything but a radical opinion seems heartless. Stem cell research could open doors for science, letting us test new drugs, which could one day cure cancer or AIDS. However, is that worth the cost of a human life?
