AIDS is an acronym for Acquired Immune Deficiency Syndrome and is thought to be caused primarily by a virus that invades white blood cells (lymphocytes) and certain other body cells including the brain.

Although treatments for both AIDS and HIV exist to slow the virus" progression in a human patient, there is no known cure. The rate of clinical disease progression varies widely between individuals and has been shown to be affected by many factors such as host susceptibility.

AIDS is thought to have originated in sub-Saharan Africa during the twentieth century and is now a global epidemic.

In 1983 and 1984, French and U.S. researchers independently identified the virus believed to cause AIDS as an unusual type of slow-acting retrovirus now called "human immunodeficiency virus" or HIV. Like other viruses, HIV is basically a tiny package of genes. But being a retrovirus, it has the rare capacity to copy and insert its genes right into a human DNA.

Once inside a human host cell, the retrovirus using its own capacities begins to copy its genetic code into a DNA molecule which is then incorporated into the host's DNA. The virus becomes an integral part of the person's body. But the viral DNA may sit hidden and inactive within human cells for years, until some trigger stimulates it to replicate.

Thus HIV may not produce illness until its genes are "turned on" five, ten, fifteen or perhaps more years after the initial infection.

During the latent period, HIV carriers who harbor the virus without any sign of illness can unknowingly infect others. On average, the dormant virus seems to be triggered into action three to six years after first invading human cells. When switched on, viral replication may speed along, producing new viruses that destroy fresh lymphocytes. As viral replication spreads, the lymphocyte destruction virtually sabotages the entire immune system.

In essence, HIV viruses do not kill people, they merely render the immune system defenseless against other infections, e.g. yeast invasions, toxoplasmosis, cytomegalovirus, massive herpes infections, special forms of pneumonia that kill in half of all AIDS patients.

That is AIDS. There are several types of AIDS. No one has been cured up to the present moment.

Translation:

AIDS is an abbreviation for Acquired Immune Deficiency Syndrome. AIDS is believed to be caused primarily by a virus that attacks white blood cells (lymphocytes) and certain other cells in the body, including the brain.

There is a cure for AIDS and HIV, but it only slows down the course of the disease, it cannot cure the disease. The clinical presentation of the disease is highly dependent on the individual and is influenced by many factors, including susceptibility to the disease.

AIDS is believed to have originated in the Sahara Desert region of Africa in the 20th century and has now caused an epidemic on a global scale.

In 1983-1984, French and American researchers independently isolated this virus, which was thought to cause the development of an unusual type of delayed-acting retrovirus, now called "human immunodeficiency virus" or HIV. Like other viruses, HIV is basically a tiny set of genes. But because it is a retrovirus, it has the rare ability to copy and integrate its genes directly into human DNA.

Once inside the human body, the retrovirus, using its own resources, begins to copy its genetic code into a DNA molecule, which is then included in the host's DNA. The virus becomes an integral part of the human body. But virus-infected DNA can sit secretly and dormant in human cells in for many years, until some kind of trigger activates it to reproduce.

Thus, HIV may not cause disease until its genes are "turned on", for five, ten, fifteen, or perhaps more years after initial infection.

During the latency period, HIV carriers who are not affected by the virus may unknowingly infect others. On average, a dormant virus is believed to reactivate three or six years after entering the human cells. Once activated, viral replication can ramp up, producing new viruses that destroy fresh lymphocytes. Spreading, they destroy lymphocytes, which actually paralyzes the immune system.

In fact, HIV viruses do not kill people, they just make the immune system defenseless against other contagious diseases, such as fungi, toxoplasmosis, cytomegalovirus, severe herpes, special forms of pneumonia, which kill AIDS patients in half of all cases.

This is what AIDS is. There are several types of AIDS. And so far no one has been able to recover from it.

People nowadays are more health-conscious than they used to be. They understand that good health is above wealth.

To be healthy we should avoid different bad habits that can affect our health. In my opinion, smoking and drinking too much alcohol, are the worst ones. It's common knowledge that smoking and drinking can shorten our lives dramatically. Smoking, for example, causes a number of heart and lung diseases, such as pneumonia, emphysema and cancer. Besides, it makes your teeth yellow and skin unhealthy. Fortunately, in recent years smoking has received a lot of bad publicity, and fewer people smoke nowadays. Smoking has been banned in most public places because everyone agrees it does harm to our health. I don't smoke, because I don't want to have unhealthy skin and teeth and die young.

Smoking and drinking are joined by less dangerous habits, such as skipping meals, eating unhealthy food, or even overeating. Of course, they are not quite as deadly as smoking or drinking alcohol, but they also affect our health.

If we eat too much, we "ll become obese, and obesity leads to serious health problems. A lot of people like drinking coca cola and coffee, and enjoy pizzas and hamburgers. But what is tasty is not always healthy. Fast food makes you fat, that's why Americans are the fattest people in the world.

In recent years eating habits have undergone a change. People are encouraged to eat less fat and more fibre. Fat is believed to be one of the major causes of obesity and heart disease. High fiber and low fat foods can now be found in all shops and supermarkets. Salads, beans, and fruit have taken the place of steak and ice cream. The fashion for health food is growing all the time.

To my mind, the only way to stay healthy and to keep fit is by going in for sports. Among the benefits of regular exercise are a healthier heart, stronger bones, quicker reaction times and more resistance to various illnesses. Besides, you can eat and drink as much as you want because you are burning it all off.

To be healthy, it is also very important to spend a lot of time in the open air. It is useful to go for a walk before going to bed, or to air the room.

I think it is very important to be fit and healthy, and it is necessary to take care of your health. Being fat, in fact, can cause real problems. It is harder for fat people to get a good job, or even to make friends. If you want to do well, you must be thin. That's why I go in for sports on a regular basis. I have been doing aerobics for three years and I feel great. I am not enthusiastic about strict dieting, but I try to eat only low-fat food, and fruit and vegetables which are rich in vitamins.

Personally I believe that regularity in life promotes our health. Sleeping eight or nine hours, getting up early, regular meals, a healthy diet and go.

For people who want to constantly improve, learn something and constantly learn something new, we have specially made this category. It contains exclusively educational, useful content that you will definitely enjoy. A large number of videos, perhaps, can even compete with the education that we are given at school, college or university. The biggest advantage of instructional videos is that they try to provide the latest, most up-to-date information. The world around us in the era of technology is constantly changing, and printed educational publications simply do not have time to give out fresh information.

Among the videos you can also find educational videos for children. preschool age. There your child will be taught letters, numbers, counting, reading, etc. Agree, a very good alternative to cartoons. For students primary school You can also find English language training, help in studying school subjects. For older students, training videos have been created that will help prepare for tests, exams, or simply deepen their knowledge in a particular subject. The acquired knowledge can qualitatively affect their mental potential, as well as please you with excellent grades.

For young people who are out of school, in university or not, there are plenty of entertaining educational videos available. They can help them deepen their knowledge of the profession for which they are studying. Or get a profession, such as a programmer, web designer, SEO optimizer, and so on. Universities do not teach such a profession yet, so you can become a specialist in this advanced and relevant area only by self-education, which is what we try to help by collecting the most useful videos.

For adults, this topic is also relevant, since it often happens that after working in the profession for years, it comes to the understanding that this is not yours and you want to learn something more suitable for yourself and at the same time profitable. Also among this category of people there are often videos on the type of self-improvement, saving time and money, optimizing their lives, in which they find ways to live much better and happier. Even for adults, the topic of creating and developing your own business is very well suited.

Also among the educational videos there are videos with a general focus, which are suitable for almost any age, in which you can learn about how life originated, what theories of evolution exist, facts from history, etc. They perfectly expand the horizons of a person, make him a much more erudite and pleasant intellectual interlocutor. Such educational videos, indeed, it is useful to watch for everyone without exception, since knowledge is power. We wish you a pleasant and useful viewing!

In our time, it is simply necessary to be what is called "on the wave." This refers not only to news, but also to the development of one's own mind. If you want to develop, explore the world, be in demand in society and interesting, then this section is for you.

Incurable Diseases

Health is important in our everyday life. Usually people name stress as one of the enemies of their health. But in fact, we don`t wish to think about the reasons of our diseases, but still we are afraid of really dangerous diseases. Most of all we are afraid of cancer.

Then, there are the following diseases on the list of the incurables ones: Alzheimer`s disease, heart diseases, cerebrovascular accidents, loss of vision; and these diseases in comparison with some simple illnesses as the problem with weight or the lost of attractiveness are really dangerous.

Infarctions and cerebrovascular accidents carry away more lives than any other disease, including cancer. Psychologists comment upon it in the following way: "Cancer is a serious illness, one knows about it beforehand and has to live with this further. As for heart diseases people think that they will either die immediately or they will be cured of this or that heart disease."

It`s curious to find out that every fourth is more afraid of AIDS or Avian influenza than the loss of hearing ability, obesity, and respiratory system diseases.

"Well, before one battles with these mysterious diseases, our attention should be paid to more banal illnesses", one of the doctors said.

But I think that we should be aware of everything in this world. The list of the incurable diseases is rather big. AIDS, cancer and avian flu are only three of this big list but they are not less serious than others.

My Daughter Learned to Count

My daughter woke me around 11:50 last night. My wife and I had picked her up from her friend Sally's birthday party, brought her home, and put her to bed. My wife went into the bedroom to read while I fell asleep watching the Braves game.

“Daddy,” she whispered, tugging my shirt sleeve. “Guess how old I’m going to be next month.”

“I don't know, beauty,” I said as I slipped on my glasses. “How old?”

She smiled and held up four fingers.

He Stood Against My Window

I don't know why I looked up, but when I did I saw him there. He stood against my window. His forehead rested against the glass, and his eyes were still and light and he smiled a lipstick-red, cartoonish grin. And he just stood there in the window. My wife was upstairs sleeping, my son was in his crib and I couldn't move. I froze and watched him looking at me through the glass.

Oh, please, no. His smile never moved but he put a hand up and slid it down the glass watching me. With matted hair and yellow skin and face through the window.

Don't be scared of the monsters, just look for them. Look to your left, to your right, under your bed, behind your dresser, in your closet but never look up, she hates being seen.

What's in the basement?

Mommy told me never to go into the basement, but I wanted to see what was making that noise. It kind of sounded like a puppy, and I wanted to see the puppy, so I opened the basement door and tiptoed down a bit. I didn't see a puppy, and then Mommy yanked me out of the basement and yelled at me. Mommy had never yelled at me before, and it made me sad and I cried. Then Mommy told me never to go into the basement again, and she gave me a cookie. That made me feel better, so I didn't ask her why the boy in the basement was making noises like a puppy, or why he had no hands or feet.

“Yeeeeeeeees?”

When I was a child my family moved into a big old two-floor house, with big empty rooms and creaking floorboards. Both my parents worked so I was often alone when I came home from school. One early evening when I came home the house was still dark.

I called out, “Mum?” and heard her sing song voice say “Yeeeeees?” from upstairs. I called her again as I climbed the stairs to which room she was in, and see again got the same “Yeeeeees?” reply. We were decorating at the time, and I didn't know my way around the maze of rooms but she was in one of the far ones, right down the hall. I felt uneasy, but I figured that was only natural so I rushed forward to see my mum, knowing that her presence would calm my fears, as a mother's presence always does.

Just as I reached for the handle of the door to let myself in to the room I heard the front door downstairs open and my mother call “Sweetie, are you home?” in a cheery voice. I jumped back, startled and ran down the stairs to her, but as I glanced back from the top of the stairs, the door to the room slowly opened a crack. For a brief moment, I saw something strange in there, and I don't know what it was, but it was staring at me.

All I saw was red

I checked into a small hotel. It was late and I was tired. I told the woman at the desk that I wanted a room. She gave me the key and said, “One more thing - there is one room without a number on your floor and it is always locked. Don't even peek in there." I took the key, went into my room and tried to sleep. Night came and I heard trickling of water. I could not sleep, so I opened my door and went into the hall. The sound was coming from the room with no number. I pounded on the door. no response. I looked into the keyhole and saw nothing except red. Water was still trickling. I went down to the front desk to complain. “By the way who is in that room?” She looked at me and told me the story. There was a woman in there. She was murdered by her husband. Her skin was all white, except for her eyes, which were red.
