The HIV Epidemic
The HIV virus, which causes AIDS, was first recognized as a new and distinct clinical entity in 1981. Since then it has become a universal epidemic concerning all of mankind.(3) This epidemic is caused by the human immunodeficiency virus, also known as HIV. HIV belongs to the retrovirus family, a family of RNA viruses noted for possession of a viral reverse transcriptase.(2) Reverse transcriptase allows a retrovirus to synthesize DNA (deoxyribonucleic acid) from their RNA. HIV like all viruses replicates inside a host cell. By seizing a host cell, the HIV virus starts with the entry into the host cell. The host cell is a cell with a surface molecule called cluster designation 4 or CD4.(2) These molecules are known as CD4+ cells. The virus surface molecules, which are classified as glycoprotein protrude from the surface of the virus and bind tightly to the CD4+ molecule on the cell surface. The membranes of the cell and virus then fuse together.
The next process the virus undergoes is reverse transcription and DNA synthesis. The HIV virus releases the enzyme, reverse transcriptase, which converts viral RNA into

Twister And Its Scientific Innacuracy

Twister And Its Scientific Innacuracy

Bill Paxton and Helen Hunt starred in the movie ?Twister?. These two characters showed hardcore dedication to the life of tornado chasing. Along with courage while chasing tornadoes, a love story was intertwined as well. The depictions of tornadoes in the movie were beautiful and done quite well but not scientifically accurate. The special effects to create the tornadoes were done very well and also very realistic to one who is not educated about tornadoes. As for those who are, this movie is almost a disgrace to their job. A tornado chasers job is understated and not credited enough as they help to warn and save people?s lives.
Certain events and weather portrayals were inaccurate. For instance, the air debris goes in toward the tornado and not out. 18 wheel trucks, farm equipment, cows and houses are being flung away when really they would be taken in. All tornadoes have a vertical vortex with an inward flow. They go counterclockwise whipping things inside. As for the wind blowing in the actor?s hair, they were blowing behind them and they should be blowing in front of them on many angles.

The Living Constitution

The Living Constitution

The ?Living Constitution?

One of the main influences among the minds of Americans is the notion of the federal constitution is a ?living document.? What does this mean exactly It means that the constitution was written to lay a foundation of laws for our country to follow, but instead it means that the federal government interprets the law in way it sees fit and rarely even pays attention to what the original document was trying to say. Through our system of government a law can be amended to whatever the government sees fit at that time with very little regard to what the framers of our constitution had in mind. The main question of concern is where does the adaptation and amendments stop. In twenty or thirty years will there be any original constitution left or will it all be what the government of that era sees as best. This is a major problem in the legal systems of our country right now, because if you keep changing the foundation to an already great nation soon it is going to fall.

Heart Attack

Heart Attack

Myocardial infractions

Coronary arteries are blood vessels that deliver oxygenated blood to the heart. All muscles in the heart require oxygen to operate correctly. When there is restriction of blood flow to the heart, the coronary arteries become blocked or narrowed. When the heart cannot get oxygen, the heart muscle is damaged and heart attacks occur. A heart attack is also known as a myocardial infraction. The symptoms of a heart attack can vary, but is commonly described as squeezing, burning, tightness, and pressure across the chest. This discomfort may also radiate to the left arm, neck and jaw. Nausea, vomiting and dizziness are other symptoms that heart attacks may include. Once a patient has a heart attack, they may undergo a complex surgical procedure. This procedure consists of three components, a cardiac catheterization, a coronary angioplasty, and a triple vein coronary artery bypass graft (CABG).
In order to determine the proper treatment, first the doctor must determine the extent of damage to the heart. There are a variety of tests that are available, but the most common procedure is a cardiac catheterization. A cardiac catheterization is performed in a special lab under local anesthetic and sterile conditions. A catheter tube is

Andrew Johnson had a history of politics and came from the slave state of Tennessee, but refused to resign as United States senator when the state seceded. When Reconstruction began in1865, he worked to preserve the Union and won the office of vice president in March 1865. When President Abraham Lincoln was assassinated only 6 weeks after his inauguration, democrat Andrew Johnson became the 17th President of the United States during the nations greatest crisis, the Civil War. In February, 1868, Johnson notified Congress that he had removed Edwin Stanton as Secretary of War and replaced him with General Lorenzo Thomas. Stanton refused to abandon his office and had Thomas arrested for attempting to exercise the duties of the Secretary of War. The House of Representatives charged Johnson with violating the Tenure of Office acts which forbids the President to dismiss any federal officeholders without approval by the Senate. On Feb. 24, 1868, the House of Representatives voted 126 to 47 to impeach Johnson. Johnson?s trial in the Senate, which he did not attend, began on March 23.

Guns And Monsters

Guns And Monsters

The representation of violence exacted upon women in cinema is inextricable from being projected upon all women. To provide a scene that objectifies the female is to reduce the feminine form to its non-dual state, e.g., a sexual object providing a vessel for male gratification (hubris and sexual) rather then being defined by its duality of sentient and physical forms. Those who construct scenes of violence against women are bound to a moral responsibility to subjectify the woman?s perspective, thus reestablishing the female as a victim rather then an object and rendering the act of violence intelligible (deplorable, open to interpretation).
The cast of Quentin Tarantino?s Kill Bill Volume 1 is predominantly female, the main character (?The Bride?) is a fearless heroine who battles other savage villainesses. However, this film?s revenge plot is based on acts of sexual and physical violence (The Bride?s is intended to be murdered, raped, and believes her unborn child was killed) which do not objectify The Bride. Rather then being objectified, she is depicted as a woman who?s honor was forcibly removed. She is reduced to a coma state (an object) by those who victimized her; when she awakens she seeks

Heart Attack

Heart Attack

A blockage in the hearts arteries may reduce or completely cut off the blood supply to a portion of the heart. This can cause a blood clot to form and totally stop blood flow in a coronary artery, resulting in a heart attack, which is also called an acute myocardial infarction (MI).

Irreversible injury to the heart muscle usually occurs if medical help is not received promptly. Unfortunately, it is common for people to dismiss heart attack symptoms.

The American Heart Association and other medical experts say the body likely will send one or more of these warning signals of a heart attack:

Uncomfortable pressure, fullness, squeezing or pain in the center of the chest lasting more than a few minutes.
Pain spreading to the shoulders, neck or arms. The pain may be mild to intense. It may feel like pressure, tightness, burning, or heavy weight. It may be located in the chest, upper abdomen, neck, jaw, or inside the arms or shoulders.
Chest discomfort with lightheadedness, fainting, sweating, nausea or shortness of breath.
Anxiety, nervousness and/or cold, sweaty skin.
Paleness or pallor.
Increased or irregular heart rate.
Feeling of impending doom.

Health Topics

Health Topics

The number one health concern among Americans today is health insurance. The entire population regardless of income, ethnicity, gender, and age is effected by health insurance or the lack there of. The type of health insurance an individual has determines the type of medical attention that will be received. If a person has really good insurance i.e. Blue Cross Blue Shield, it?s more than likely that that person will attend a private practice health facility, where as one with no or government assisted insurance he/she would attend a more public facility such as the health department or local clinics. The person that attends the more public health facility is capable of acquiring a disease than one who attends a private facility. Causing more problems in that person?s health.
Fraud is also apart of health insurance. Because of parents not able to pay for health insurance they lie on forms to try to obtain government assisted insurance i.e. Medicaid. Although this is not the best insurance it?s affordable. And because this is a form of insurance, cardholders can

Third Cinema

THIRD CINEMA

First cinema, according to Solanas?s definition, ?expresses imperialist, capitalist [or] bourgeois ideas. ? Any cinematographic expression [likely] to respond to the aspirations of big capital [is] first cinema? (Karpenko). Hollywood and commercial type films fit into this definition. Individualistic characters leads into the star system. The film language in first cinema is basic, structured, and understandable. Second cinema ?expresses aspirations of the middle stratum, the petite bourgeoisie. Second cinema is often nihilistic, mystifactory. It runs in circles. It is cut off from reality? (Karpenko). Independent films in America are usually referred to as second cinema. ?It is made outside the Hollywood system, but many times, it is outside looking in? (Karpenko). There is more experimentation and not such a regular film structure.
Third Cinema films are films that the system can not be incorporated as visual pleasure. They are the most radical and extreme. They focus on causes, not effects, and embraces imperfection while being politically engaged. It is a repository of popular memory. In Espinosa?s For an Imperfect Cinema he says ?Nowadays perfect cinema?technically and artistically masterful ? is almost always reactionary cinema.? Third
