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

5.As a result of Alzheimer’s research, there are an array of drugs in development that scientists believe have great potential to effectively treat the disease.()
What is it about a dog's gaze that makes it so charming？ A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.
The cuddle chemical has another, more scientific name: oxytocin.Oxytocin is a substance in the blood that encourages bonding.Levels of oxytocin increase, for example, when a mother feeds her newborn baby.According to Nagasawa's study, the same is true when we look deeply into the eyes of a dog.
The results of this study can tell us a lot about the history of the bond between humans and dogs.It all started somewhere tens of thousands of years ago.Scientists believe that wolves used to follow humans who were hunting large animals.The wolves would eat the food left behind by the humans.
Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.
Over time, the wolves that interacted with the humans began to change.They became more loyal to their human partners.The wolves and humans started to depend on each other and bond with each other.These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie evolved to better survive in their environment.
This process depended a great deal on the bond humans formed with them.And according to Nagasawa's study, this bond was formed with the help of oxytocin, the cuddle chemical.

One of the most comprehensive ventures was the restoration and transformation of Boston’s eighteenth century Faneuil Hall and the Quincy Market, designed in 1824.This section had fallen on hard times, but beginning with the constuction of a new city hall immediately adjacent, it has returned to life with the intelligent reuse of these fine old buildings under the design leadership of Benjamin Thomson.He has provided a marvelous setting for dining, shopping, professional offices, and simply walking.
Butler Square, in Minnespois, exemplifies major changes in its comples of offices, commercial space, and public amenities carved out of a massive pile designed in 1906 as a hardware warehouse.The exciting interior timber structure of the’building was highlighted by cutting light courts through the interior and adding large skylights.

The period of Middle English extends roughly from the twelfth century through the fifteenth.The influence of French(and Latin,often by way of French)upon the vocabulary continued throughout the period,the loss of some inflections and the reduction of others accelerate, and many changes took place within the grammatical systems of the language.A typical prose passage, especially one from the later part of the period, will not have such a foreign look to us as the prose of Old English, but it will not be mistaken for contemporary writing either.
The period of Modern English extends from the sixteenth century to our own day.The early part of this period saw the completion of a revolution in vowel distribution that had began in late Middle English and that effectively brought the language to something resembling its present pattern.Other important early developments include the stabilizing effect on spelling of the printing press and the beginning of the direct influence of Latin, and to a lesser extent.Greel pm the vocabulary.Later, as English came into contact with other cultures around the world and distinctive dialects of English developed in the many areas which Britain had colonized, numerous other languages made small but interesting contributions to our word-stock.
