Alzheimer’s Disease: Are We Close to Finding a Cure？
First described in 1906 by Dr.Alois Alzheimer, Alzheimer s disease is the most common form. of dementia, accounting for around 60%–80% of cases.It is characterized by problems with memory, thinking and behavior.Onset is most common in individuals aged 65 and over, although people in their 40s and 50s can develop what is classed as early - onset Alzheimer’s.
Alzheimer’s is a progressive disease, meaning memory loss is mild in the beginning, but it worsens over time to the extent that individuals are unable to have conversations or respond to their surroundings.There are treatments that have been approved by the US
Food and Drug Administration (FDA) for Alzheimer’s.For example, cholinesterase inhibitors and memantine can help treat memory and thinking problems.But these drugs just help manage the symptoms; there is currently no cure for the disease.
Current Alzheimer’s prevalence in the US makes it the 6th leading cause of death, killing more than half a million seniors every year.To put this in perspective, Alzheimer’s disease currently kills more people each year than prostate cancer and breast cancer combined.There is no doubt that scientists across the world are working hard to find ways to prevent, treat and cure this debilitating condition.Hardly a day goes by without coming across a report about how scientists restored memory and learning deficits in Alzheimer’s mouse models, how vitamin D deficiency could increase the risk of developing dementia, and how DNA methylation in the brain is linked to Alzheimer’s.But what have these studies taught researchers about Alzheimer’s so far？
Preventing and Targeting Plaques and Tangles
As with all diseases, knowing exactly what causes Alzheimer’s is key to identifying ways to prevent and treat the condition.Past research has indicated that Alzheimer’s occurs when two abnormal brain structures — plaques and tangles —damage and kill nerve cells, causing the memory, thinking and behavioral problems associated wit

Improvement in reading efficiency has several major benefits. We need reading skills to benefit from the wealth of information that is now available in printed form. Most people get the rough outlines of their daily news from television and radio. However, the printed word still provides the in-depth coverage of topics that really produces well-informed people. Reading is also a great source of entertainment for many people. For students, it is the primary method of studying.
The time you now spend reading can be made much more productive by increasing your reading rate. For some people this will mean that they can obtain more information in the same length of time. For others it will mean that time now devoted to reading can be used in other more interesting and profitable ways.
To determine how fast you are reading, you first have to get some idea of the number of words in a given passage. Then you simply divide the number of words by the number of minutes it takes to read. That will give your rate in words per minute.

When Reginald Lindsay received a scholarship to Morehouse College in Atlanta, Georgia, what he wanted most was a good job with a good salary. But soon he became interested in the civil rights movement. At present he has a plan which he hopes will take him to Congress as a southern representative.Now in his first year at Harvard Law School, Reg is making careful plans. After earning his degree, he expects to return to the South to practice law among the poor. "I want to help them understand what their rights are and to help them achieve them," he says. Then he hopes to run for political office at the local and state level until he is ready to try for Congress.Reg grew up in a low-income Negro section of Birmingham, Alabama. Brought up by his grandparents after his parents were divorced while he was very young, Reg has been living through a period of far-reaching progress in race relations. In the summer of 1968 Reg himself became a good example of this progress when he became the first Negro student appointed to a special new program. The program introduces bright young students to the workings of the Georgia State government and encourages them to seek employment there after finishing their education. "I've been lucky," he says. "I seem to have been in the right place at the right time."
But luck is only part of Reg's story, for he has made the most of opportunities that came his way. He learned to read in kindergarten and began visiting the public library regularly to borrow books. His grandparents encouraged him, though neither of them had much education, and they bought him a set of encyclopedias. "I loved those books," he re- members. "I used to come downstairs before breakfast and read short articles. I enjoyed reading about famous men, and then I would pretend to be one of them. I guess it was partly a childish game and partly an escape. It wasn't too much fun to be a Negro when I was a kid."
While studying for his bachelor's degree at Morehouse College, Reg worked on several political campaigns helping candidates get elected to government offices. At the same time he maintained a "B" average while majoring in political science. He worked as a student advisor to earn extra money for his college expenses, and he was granted a scholarship for a year of study at the University of Valencia in Spain.With just two more years to complete at Harvard Law School, which also gave him a scholarship, Reg has made a good start on his professional career. He says, "The good life for me is the kind of life where I can find satisfaction in public service."

The orange pumpkin is harvested at this time of year and is hollowed out, a funny face cut into it, and a candle placed inside as a decoration in the window.City folks, nowadays, sometimes use paper pumpkins for decorations.
Some years ago, the holiday was celebrated by dressing up in strange and frightening costumes and playing tricks on one's neigh bars and friends, such as ringing door bells, throwing bits of corn on the window panes, and in other ways making minor disturbances.

Sylvester is keeping track of the distortions, and he already has quite a long list. He says that all housewives seem to live in lovely homes, dress beautifully, and love their household chores. They smile and boast about floor waxes and proudly display their dirty laundry, dusty tabletops, and filthy ovens. In addition, he has never seen men doing housework. Sylvester thinks that this view of family life is filled with distortions.I am keeping track of the people who appear in the advertisements. I have found handsome men courting the All-American Girl, and they are always recommending brand X toothpaste or brand Y cologne. I see teenagers and children surrounded by their friends, having wonderful times at parties and at school, and they are usually enjoying large harmonious family gatherings. I think that these advertisements are also filled with fantasy.Sylvester and I have concluded that much of American life is pictured unrealistically in commercials. Teenagers do not always have fun at parties, and very few people love doing chores. People do have problems, but few of these are ever shown in commercials. Instead, we watch Cinderella (灰姑娘) discover a miracle floor wax, finish the kitchen chores, and waltz off to the ball. Our heads are filled with these fantasies, and they also suggest that, for any problem, brand Z will provide the instant cure. Sylvester and I will have very few facts and a lot of fantasy to write about in our research reports.
