Our Aging Population
In the year 1900, only about 4% of the people in the United States were over 65 years old. In the year 2000, that figure was up to nearly 13%. By the year 2030, it is estimated that more than 20% of the U.S. population will be over the age of 65.
The increase in the nation’s elderly population is a good sign that our overall health is improving. However, now that more and more people are living to old age, age-related diseases that our ancestors rarely lived to see are also more common. One of the most devastating is Alzheimer’s disease, in which the nerve cells in the brain clump into tangled, knotty plaques that interfere with memory, thought, and ultimately, even movement. The risk of developing Alzheimer’s disease increases dramatically between the ages of 50 and 80. About 4.5 million Americans had Alzheimer’s disease in the year 2000. By 2050, that number is expected to be somewhere between 11 and 16 million.
Beyond specific diseases that are associated with aging, older people tend to need more frequent and expensive medical care than younger people do. When people get very old, they may become physically weak and need assistance with their day-to-day living. Over the next few decades, the average age of the population will get older, since the birthrate has leveled off and will probably remain steady in the years to come. As this happens, we will certainly face serious challenges in caring for the needs of our growing elderly population.
2 British Tourists Make Love The Beach In Dubai,Who Was Sentenced To 3 Months Imprisonment
Dubai, United Arab Emirates court in recent days on the beach in order to “sex” on the ground, two British tourists sentenced to 3 months imprisonment in addition to 157 pounds fine and deportation. When the court when the two of them and their lawyers did not appear in court.
Dubai court held that the two men took place in public, “sex” is the misconduct should be punished. A man and a woman, two British tourists have refused to acknowledge their guilt, but they admit that unauthorized drinking. Their lawyer Matar told the Reuters reporter said, “This decision does not make sense, I will definitely appeal.”
As the sun was shining all year round in the Gulf region, Dubai, also the world’s largest man-made island and the highest skyscraper and a duty-free policy in recent years the Dubai Tourism increasing the number of foreign tourists, local business and promote the development of tourism . There is also the Gulf region adhere to the most traditional, most conservative. The rapid development of tourism at the same time, civilizations, cultures and the collision of intense conflict have staged. It was pointed out that foreigners “filthy, degenerate,” the act of violation of local laws, as the country’s strict ban on alcohol, and homosexuality in public places, such as over-intimate behavior.
Hormonal Contraception In Women With HIV Infection
A multicentre study in Kenya, Thailand and Zimbabwe has been assessing the impact of different contraceptive methods on the clinical course of HIV infection. A total of 623 women, most of whom were using hormonal contraceptives at the time of enrolment, were followed every six months to determine disease progression, the incidence of opportunistic infections, and changes in CD4+ cell count and viral load. Provisional data show a much steeper decline in CD4+ counts in Thailand and Zimbabwe than in Kenya, regardless of contraceptive method used. This may reflect the impact of different HIV subtypes. The study was discontinued at the end of 2005 because of lack of funds and data analysis is ongoing.
Children contribute to the advancement of women’s intellectual
By brain
Most of the new mother will often feel tired, have a simple small effort to complete.
British “Daily Mail” quoted U.S. 12, Richmond, Virginia University neurology professor Craig’s words: “Indeed, when a pregnant woman to undergo a so-called ‘baby brain’ time, they will be part of the brain function decline. But This is because they are part of the brain function is changing in response to the upcoming new challenges. ”
“These changes from the (pregnant) then, you can extend life,” he said, “These changes to the promotion of mother’s cognitive ability in old age and to prevent them from suffering from functional degradation of the disease.”
Kingsley plans to hold next month, the Institute of Neurology annual meeting on the results of this report.
The experiment
Professor and his colleagues found that pregnant women-term memory and verbal expression is able to cut a temporary phenomenon, which is part of the process of remodeling the brain, the brain and most of the remodeling process of good people.
Kingsley on rats and primates, and other experiments found that female post-reproductive animals become more courageous.
The study found that fertility has been unable to have children than an animal in the animal feeding speed 5 times faster, but also have a better sense of space.
The researchers compare the brain and found that animals after the birth of the new skills and physical changes related to the brain. For example, some of the brain and the ability of future generations of education-related nerve cells in the female reproductive young animals grow larger, with the adjacent nerve cells more closely linked.
Kingsley believes that the outcome of the Institute of Zoology, was also applicable to human beings. He said: “women to become mothers will be many of the physiological benefits of physical reproductive challenges faced by the brain after the brain to enhance women’s reproductive benefit from the brain to make the process difficult.”
To be worked out
There are previous studies suggest that pregnant women after the memory and reasoning ability. Britain Lunduihamo Angelaao Partridge Smith Hospital in 2002 reported that pregnant women researchers conducted brain scans found that 4 percent of their brain to narrow.
Last year, two Australian researchers believe that pregnant women after the verbal memory and the ability to reduce expression.
However, the researchers also found that the fertility of female positive impact.
University of Toronto study found that rats after birth to reduce the level of a protein in the body, which reduces the risk of their functional degradation of the risk of disease. This protein in Alzheimer’s disease and human neurodegenerative diseases.
Boston University associate professor in the Department of Medicine study found that Thomas had Poer Si, after the 40-year-old pregnant woman lived to 100 years old is more likely.
Obesity Can Affect Male Fertility
Pennsylvania State University School of Medicine researchers in the United States, “fertility and infertility,” the magazine published a research report said 87 of their 19-year-old to 48-year-old healthy men were investigated and found that obese men make changes in hormone levels, Led to the decline in fertility.
The team of Eric Cook said, with a thin men, fat men in the blood levels of low testosterone, luteinizing hormone and follicle-stimulating hormone is also relatively low, after the two hormones is very important for fertility.
Cook said the results show that obesity is a cause of infertility as a factor.
The team found that surveyed 87 men, have accounted for 68% of the children. Their average body mass index of 28 are overweight; men without children average body mass index of 32 are obese.
The researchers surveyed men of reproductive hormone testing found that the higher the degree of obesity, luteinizing hormone and follicle-stimulating hormone levels lower, and the higher the level of estrogen.
The researchers explained that obesity may promote testosterone into estrogen, the hormone changes that will signal the brain to suppress luteinizing hormone and follicle-stimulating hormone generation.
The researchers pointed out that past studies have shown that obesity would lead to loss of libido and erectile dysfunction occurred increased. These effects and the Institute found that the hormone might be changes in the role of the joint, weakening of the obese male fertility.
