Blood Cancer 'Leukemia' (Biology Project)

Here you can find some useful info.
about the terrible blood cancer...





Leukemia is a disease that refers to a group of blood diseases characterized by cancer of the tissues that produce blood.
In more detail, the leukemia is a diverse group of neoplastic diseases, characterized by an abnormal multiplication or malignant or malignant transformation of blood-forming cells in bone marrow and lymphoid tissue. Normal cells in the bone marrow was replaced by normal or abnormal cells. These abnormal cells from the marrow and can be found in the peripheral blood or peripheral blood. Leukemia cells affecting hematological or blood cell formation process is normal and the patient's body immunity.


Leukemia can be classified on the basis of a natural way of disease: acute and chronic. Acute leukemia is marked by a very rapid course of the disease, deadly, and worse. If not treated immediately, the patient can die within weeks to days. While chronic leukemia have a disease that does not travel so quickly that it has a longer life expectancy, up to more than one year.

Causes 
The cause of leukemia is not known with certainty,
but note several factors that can affect the frequency of leukemia, such as:
1. Radiation
2. Factor 
leukemic
There are several chemicals that have been identified may affect the frequency of leukemia:

• environmental toxins such as benzene

• industrial chemicals such as insecticides

• Drugs for chemotherapy

3. Epidemiology

• In Africa, 10-20% patients with acute myelogenous leukemia (LMA) has kloroma around orbital eye

• In Kenya, China, and India, Chronic myelogenous leukemia (CML) of patients aged 20-40 years

• In East Asians and East Indians Chronic lymphocytic leukemia is rarely encountered (LLK).

4. Hereditary

Down syndrome patients have acute leukemia incidence 20 times greater than normal people.

5. Virus

Viruses such as retroviruses can cause leukemia and feline leukemia virus.


Treatments 
Treatment of acute blood cancer (acute leukemia) according Mediayarti curative or palliative aims:
Curative treatment includes:
1. Siteroduksi with the drug combination cytostatica cytostatica ranging from mild to aggressive with the need of "rescue" the patient's blood iduh cells from peripheral blood to rescue the bone marrow ablation.

2. Allogeni blood stem cell transplantation or autologous bone from marrow, peripheral blood or umbilical cord.

3. Supportive, through blood transfusion, vitamin B6 and 12, iron, adequate nutrition, antibiotics and anti-fungal if there is any indication.

While the treatment of chronic leukemia depends on the type and phase or stage where the patient is found.

Global communication

Global communication is the process of transmitting and receiving information on a world-wide scale. People have been doing it over centuries. The main reason is to get related to the outside world and people in it. This continuing process is transforming our society day after day. The way people work, think and deal with different situations is not the same any more.
However, the evolution of global communication can be linked closely to the evolution of technology. Global markets now offer the ability to produce cheaper products, access to consumers in foreign countries, new sources of finance and income, new sources of technology and access to a world of people with know-how. (Stevens, Miller & Michalski, 2000). One example of this is the internet which has altered the world drastically in the last ten years. Never has social interaction with people around the world been as easy as it is at present. Not only can a person automatically send an email to any area in the world, but they can send simultaneous copies to a variety of locations or post a message able to be retrieved by anyone with access. This and other media products are part of our everyday life by helping us to be part of everything that is happening over there!

The Contribute of the Victorians to the modern civilization!

The Victorians lived over one hundred and fifty years ago during the reign of Queen Victoria (1837 to 1901).Victorian times means during Victoria's rule,the time Queen Victoria was on the throne for over 64 years. Living then was really difficult.There was no electricity, instead gas, lamps or candles were used for light.There were no cars. People either walked, traveled by boat or train or used coach horses to move from place to another.The Victorians are so famous because they managed to build a huge empire in that period of time.It was also a time of tremendous change in the lives of British people. In 1837 most people lived in villages and worked on the land; by 1901, most lived in towns and worked in offices, shops and factories.
  • Britain became the most powerful and richest country in the world, with the largest empire that had ever existed, ruling a quarter of the world's population.
  • Towns and cities got piped water, gas and, by the end of the century, electricity
  • The number of people living in Britain more than doubled from 16 million to 37 million, causing a huge demand for food, clothes and housing.
  • Factories and machines were built to meet this demand and new towns grew up, changing the landscape and the ways people lived and worked.
  • Railways, originally built to transport goods, meant people could travel easily around the country for the first time. Railways brought new foods to towns and cities.
  • The Police Force was invented.
The Victorians have given much things to the future modern civilization !
