It is rarely found on dark skinned people. It will develop into large masses unlike basal cell carcinoma, it can spread to other parts of the body. It is estimated that there are 2,300 deaths from squamous cell carcinoma every year. Another type of this cancer is malignant melanoma. Malignant melanoma is the most harmful. It develops on about 32,000 Americans annually. Every year are estimated 6,800 Americans will die from melanoma. Melanoma like its less aggressive ...
... population (sixty-two million people worldwide). Patients with von Willebrand disease have either have stopped the production of von Willebrand factor or they produce a molecule that does not function normally, which cause their platelets do not adhere properly when blood vessels are injured, therefor it takes longer for a blood clot to form. In some patients, the factor VIII (the anti-hemophilic factor that helps blood clot) is also reduced, and blood clotting is severally impaired. In patients with hemophilia, the primary problem is the decrease or absents the factor VIII, while the von Willebrand factor is normal. Erik von Willebrand, who lived in Helsinki, Fin ...
... other theories have been disputed in recent years). Freud reportedly admired Aristotle's assertion that dreaming is the activity of the mind during sleep (Fine, 1973). It was perhaps the use of the term activity that Freud most appreciated in this brief definition for, as his understanding of the dynamics of dreaming increased, so did the impression of ceaseless mental activity differing in quality from that of ordinary waking life (Fine, 1973). In fact, the quality of mental activity during sleep differed so radically from what we take to be the essence of mental functioning that Freud coined the term "Kingdom of the Illogical" to describe that realm of the hu ...
... isn't. Cigarettes are addictive and they usually lead the smoker to marijuana use or to other kind of drugs. That's why I think that young teenagers shouldn't start smoking at young age. All of you people out there who think that they can stop whenever they want, well I have news flash for you. 1 out of 10 smokers succeed in quitting smoking in United-States. Everyone thinks that they have an iron will and they keep on delaying the time to stop, I'll just stop as my new year resolution, I'll stop in a month, a week, a year. Smoking is really hard to quit, it's an addictive habit and you really need an iron will to stop it. There are also a few consequences I th ...
... of deadlock among scientists and doctors whether it's hereditary, viral, or a combination of the two, with the disease being hereditary, but with a viral trigger, or just a simple chemical imbalance in the immune system. One thing is certain, though. Some sort of defect in the immune system causes white blood cells to attack and destroy the myelin sheath. There are five main types of Multiple Sclerosis. The first type is Benign Multiple Sclerosis. It is the least severe, has little progression, and takes up twenty percent of all cases. The second type is Benign Relapsing-Remitting Multiple Sclerosis. It carries symptoms that fluctuate in severity, mild dis ...
... Ebola virus is a member of a family of RNA (ribonucleic acid) viruses known as filoviruses. When these viruses are magnified several thousand times by an electron microscope they have the appearance of long filaments or threads. Filoviruses can cause hemorrhagic fever in humans and animals, and because of this they are extremely hazardous. Laboratory studies of these viruses must be carried out in special maximum containment facilities, such as the Centers for Disease Control (CDC) in Atlanta, Georgia and the United States Army Medical Research Institute of Infectious Diseases (USAMRIID), at Fort Detrick in Frederick, Maryland (CDC I,II). The Ebola hemorrhagic fe ...
... Stay of Execution Euthanasia has become an issue of increasing attention because of Dr. Jack Kevorkian's assisted suicides. As of October 21 Kevorkian has assisted in nineteen suicides. Because of the increasing number of suicides in Michigan, Gov. Engler signed an anti-suicide law in late February that made doctor-assisted suicides a felony. During the 21-month trial period of the new law anyone assisting in a suicide can be sentenced to up to four years in prison and fined more than $2,000 (Reuters, 1993). With the passing of this law I thought that most people would be against the right-to-die, not so. In a poll cited in a 1991 issue of USA Today eigh ...
... been aborted for various reason, none of them have seen their first glimse of light, that is 10 times the number of americans killed in all our nation's wars. Make no mistake though, abortion on demand is not a right granted by the constitution. Instead Roe vs. Wade had been a continuing reminder to the conscience of this nation. The nation reflects today that we can't diminish the value of human life(the unborn child) without diminishing the value of all human life including each and everyone of us. Mother Teresa once said “Abortion is the greatest moral crisis that faces the world today. What is the real issue – how can we call a mother a mother if she ab ...
... communicate with the rest of the cells in the body. Next, the Aids virus goes after certain chemokines. Chemokines are proteins or (protein receptors) on the surface of T-cells and microphages, they are used to "talk" to, arouse, and attract cells. There are two variants of chemokines, alpha and beta chemokines. Among these there are many different chemokines from CCR5, CCR3, CXCR4, etc… Now AIDS needs the CD4 molecule and the CCR5 protein to be present on a T-cell to successfully infect the cell. It needs the CD4 molecule to latch on to the cell. Once this is accomplished it needs the CCR5 protein to be able to get inside of the cell in order to infect it. ...
... at a comparable level of development. In order to be diagnosed with ADHD some symptoms that cause impairment must have been present before seven years of age. Also some impairment from the symptoms must be present in at least two settings such as work, home or school. It is very unusual for an individual to display the same level of dysfunction in all settings or within the dame setting at all times. There must also be clear evidence of interference with developmentally appropriate social, academic, or occupational functioning (First, 1994, p.78). A person must have a certain number of symptoms under Inattention, Impulsivity and Hyperactivity. For In ...
