Certain birds were also believed to play a key role in fertility. for example, Hindus and Egyptians believed that the ibis was the bird that ensured a pregnancy.

Introduction
The issue of therapeutic and reproductive cloning has much been discussed during the last decade all over the world. Moreover, everyone involved in the debates has had a different but a clear-cut opinion on the issue meaning that cloning is either extremely good or it is nothing else but evil. Specifically, after Dolly, the sheep, was cloned, people were threatened by the possible future infinite reproduction of dictators, supermodels and geniuses. Consequently, UNESCO and the Council of Europe have independently declared that human reproductive cloning is unethical because it violates “human dignity”. The advisory commission on human cloning established by the European Commission has supported this idea as well. Furthermore, almost every Christian philosopher and many secular philosophers have also warned of dire consequences if cloning experiment is going to continue in the future. They claim that cloning, both reproductive and therapeutic, must be abolished because it is unethical in the sense that a potential human life is being destroyed. Philosophers also contend that those who support this medical research are nothing else but potential killers. However, a lot of scientists and doctors strongly support stem cell research and cloning for medical purposes because it has a potential to save lives of millions sick people all over the world.

Hepatitis Essay example:
Throughout the years, many diseases have had significant effects on the world such as Ebola, AIDS, and the plague. Hepatitis is one of them. Hepatitis is defined as any irritation of the liver, or anything that makes it inflamed. It also described a group of infectious diseases cause by viruses that attack the liver. There are six different types of the disease that have already been discovered. They are Hepatitis A, B, C, D, E, and G. All of these end up causing disease except for Hepatitis G, which just lives in the blood and does not cause the infectant to show signs of any illness (Berkman 2). Although, some of the most important cases of Hepatitis deal with Hepatitis A, B, and C.
The history of Hepatitis dates back to almost the beginning of medicine. (Berkman 3) The first recorded cases of the disease were thought to have been right after the distribution of the small pox vaccine in a shipyard in Germany in 1883. During the early and middle parts of the 1900s. The disease was watched closely with the use of contaminated needles and syringes. The effect that hepatitis has on the liver is similar to the effects that alcohol causes. Both end up scaring the liver in the end. When the virus hits the liver, it causes it to be inflamed. The body’s immune system trys to fight the virus with cells called lymphocytes, which end up hurting the liver even more. Fibrosis occurs because now the liver has been scarred. When the scarring gets bad enough, the blood flow gets slower and causes cirrhosis. Then, the blood begins to back up and leak into other organs. The important functions that the liver performs (Berkman 4), such as manufacturing proteins and regulating the transport of fat stores and controlling the production and excretion of cholesterol (Berkman 3), become more difficult to do.

Tuberculosis Essay example:
Clinical Perspective
Tuberculosis (TB) is caused by Mycobacterium tuberculosis (M.TB.) and is the leading cause of death in the world from a single infectious disease. Although very little is known of the mechanisms of it pathogenesis and how to protect a person from the disease. There was a decline in TB in the United States in the last century but the disease is now increasing and there are now multiple drug resistant strains that have emerged. This increase has multiple causes some of which are changes in social structure in cities, HIV epidemic, and a failure by some public entities to improve their public health programs.
In 2002 M. TB. is responsible for more morbidity in humans than any other bacterial disease. M.TB. infects 1.7 billion people per year which is equal to 33% of the entire world population and is responsible for over 3 million deaths/year. (Todar’s 2002)
In the United States since 1985 there has been an increase in cases of M.TB. this is due largely to the increase of Human Immunodeficiency virus (HIV) infections which occurred during the same period of time. More recently there has also been an increase in the number of cases of multi drug resistant (MDR) strains of M.TB. due to patient non compliance with medication. (more…)
