Wrongly Convicted Man and His Accuser Tell Their Story
NEW YORK,NY, January 5,2010. St.Martin’s Press has announced the release of the paperback edition of Picking Cotton, a remarkable true story of what novelist John Grisham calls an “account of violence, rage, redemption(救赎)，and, ultimately forgiveness.”
The story began in 1987, in Burlington, North Carolina, with the rape of a young while college student named Jennifer Thompson. During her ordeal, Thompson swore to herself that she would never forget the face of her rapist, a man who climbed through the window of her apartment and assaulted her brutally._During the attack, she made an effort to memorize eveery detail of his face, looking for scars, tattoos(纹身)，or other identifying marks.(46)When the police asked her if she could identify the assilant(袭击者)from a book of mug shots, she picked one that she was sure was correct, and later she identified the same man in a lineup.
Based on her convincing eyewithness testimony, a 22-year-old black man named Ronald Cotton was sentenced to prison for two life terms. Cotton’s lawyer appealed the decision, and by the time of the appeals hearing, evidence had come to light suggesting that the real rapist might have been a man who looked very like Cotton, an imprisoned criminal named Bobby Poole.Another trial was held.(47)Jennifer Thompson looked at both men face to face, and once again said that Ronald Cotton was the one who raped her.
Eleven years later, DNA evidence completely exonerated(证明……清白)Cotton and just as unequivocally(明确地) convicted Poole, who confessed to the crime. Thompson was shocked and devastated.(48) “The man I was so sure I had never seen in my life was the man who was inches from my throat, who raped me, who hurt me, who took my spirit away, who robbed me of my soul,” she wrote. “And the man I had identified so surely on so many occasions was absolutely innocent.”
_Jennifer Thompson decided to meet Cotton and apologize to him personally.(49) Remarkably both were able to put this tragedy behind them, overcome the racial barrier that divided them, and write a book, which they have subtitled “Our memoir of injustice and redemption.”
Nevertheless, Thompson says, she still lives “with constant pain that my profound mistake cost him so dearly_I cannot begin to imagine what would have happened had my mistaken identification occurred in a capital case_(50)”

More about Alzheimer's Disease
Scientists have developed skin tests that may be used in the future to identify people with Alzheimer's disease1 and may ultimately allow physicians to predict who is at risk of getting this neurological disorder.
' The only current means of diagnosing the disease in a living patient is a long and expensive series of tests that eliminate every other cause of dementia.
“ Since Alois Alzheimer described the disease nearly a century ago，people have been trying to find a way to accurately diagnose it in its early stages，” said Patricia Grady，acting director of the National Institute of Neurological Disorders and Stroke in B医学全在线网站www.med126.comethesda, Maryland. "This discovery, if confirmed, could prove a big step forward in our efforts to deal with and understand the disease. ”
Alzheimer's is the single greatest cause of mental deterioration in older people, affecting between 2. 5 million and 4 million people in the United States alone. The devastating disorder gradually destroys memory and the ability to function，and eventually causes death. There is currently no known treatment for the disease.
Researches discovered that the skin cells of Alzheimer' s patients have defects that interfere with their ability to regulate the flow of potassium in and out of the cells. The fact that the cell defects are present in the skin suggests that Alzheimer's resultsfrom physiological changes throughout the body，and that dementia may be the first noticeable effect of these changes as the defects affect the cells in the brain, scientists said.
The flow of potassium is especially critical in cells responsible for memory formation. The scientists also found two other defects that affect the cells' supply of calcium, another critical element.
One test developed bywww.med126.com researches calls for growing skin cells in a laboratory culture and then testing them with an electrical detector to determine if the microscopic tunnels that govern the flow of potassium are open. Open potassium channels create a unique electrical signature.
A spokesman for the Alzheimer's Association said that if the validity of the diagnostic test can be proven it would be an important development, but cautioned that other promising tests for Alzheimer's have been disappointing.
