Virus. Classification
One of the strangest bodies in nature are the virus, Are so rare and strange, that it is very difficult to combat. Here and overview on what they are and what they are not viruses.
A virus is a biological organism that does not work by itself, but requires a host cell in order to be played, or at best, replicate. There is an extensive debate among biologists about whether or not they are living organisms. It seems strange that the doubt, the idea is that viruses are not cells, something that is considered almost a defining life. But they do have genes and DNA, and evolve by natural selection.
But then what is a virus? Some considered on the verge of life, which are not really living. That’s because a virus is a DNA chain or RNA wrapped in a protein called caused viral. To live and replicate a virus needs a cell invaded. Once the work, producing many copies of the invading virus.
Usually, the virus destroys the cells used to replicate, and that is why they are so harmful to living organisms that are infected by them. Not only have us humans viruses invaded us, but also to plants, fungi and all animals.
In the process of replication, viruses generate disease in humans. Some of them are the common cold, the flu, chicken pox, measles, hepatitis B, yellow fever, dengue, rabies, AIDS, and the list is almost as long as a strand of DNA.
For now the only way to fight viruses are vaccines produced immunity for a certain time. Sometimes there are viruses that can be combated with the same immune system of our body, if you need external. But there are others for which no cure.
How do cigarettes to calm down
One of the typical responses of a smoker who does not want to quit smoking is: “but I feel reassured.” True, nicotine alters the activity of certain brain areas involved in negative emotions. But at what cost? Without that most of the time the calm that is sought in the cigarette is nothing more than the addiction asking your dose of nicotine.
In an article published in Behavioral and Brain Functions, Researchers at the University of California explained that they have shown that nicotine has a calming neurological. Managed to do it with a group of non-smokers who were provoked to be angry.
Jean Gehricke, director of the study, has studied the tendency of subjects with nicotine patches, to retaliate in response to a provocation. For this study the subjects played a computer game and could see a screen with another player they believed it was his opponent. However, the fact is they were playing alone.
After each round, the winner could give your opponent a nasty burst of sound, volume and duration in a choice of winner. In some subjects, nicotine was associated with a reduced tendency to revenge, even after being provoked by his opponent.
This was related to changes in the metabolism of the brain in response to nicotine in brain areas responsible for the direction, planning and process of emotional stimuli, said Gehricke.
This study shows that people prone to anger are most susceptible to the effect of nicotine, and therefore it is easier to become addicted to smoking.
Swine Influenza | Influenza A | New Flu
The World Health Organization has raised the level of pandemic alert to the progress that is having terrible swine flu. The caveat is that no region of the world is safe from the virus, which so far has taken the lives of 149 people in Mexico.
There are also infected in United States, and suspects in Spain and United Kingdom. Both alert levels was not the case since the 1968 influenza pandemic, the Hong Kong flu. There are patients under observation in Italy, Belgium, Switzerland, Denmark, Sweden, New Zealand, Israel, Brazil, Peru and Colombia.
But what is the swine flu? How is it spread? What are the symptoms?
It is an infectious disease that is caused by a virus that has resulted in populations of pigs in Mexico. It is known as swine virus influence or swine flu, whose technical name is influenza A (H1N1).
Should be very careful people who work with birds and poultry to pigs. But the virus not only spreads from pigs to humans, but also from person to person. The swine flu is spread by contact through secretions containing the virus, or a sneeze, cough or mucus. For that reason, those with symptoms should stay down here at home and call the doctor.

- Difficulty breathing.
- Decreased appetite.
Mortality is low; most pigs were recovered after 5 or 7 days. But people just take the more severe symptoms occur in about five days, according to WHO experts say is the dangerous period. The deaths could have occurred in Mexico because the flu would have been complicated by other infections.
Swine flu, questions and answers, myths and mysteries
In another article we discussed the basics of the swine flu, but as many have left comments asking for more, we have assembled a series of questions and answers clarifying many myths that are spreading that the only thing they do is spread fear and misinformation. All questions and answers that have been made known by the health authorities of the nations affected by the outbreak of swine flu.
Is deadly swine flu?
There were many deaths in Mexico only to date, and is believed to be because it was the place from where it spread, and most of all because it was linked to other infections in those affected. In other regions have not been as severe, with the exception of the recent fatal case of the boy two years in United States.

Should people stop traveling?

Losing your job, you can get sick
Losing the job increases the likelihood of the disease, and to face a firing may increase the risk not only to diseases affecting the stomach (which is more typical), but also can develop problems such as: hypertension, cardiac, stroke or diabetes, according to a new study suggests.
In some cases, statistics have shown that the chances of getting sick because of the loss of a job have increased from 50 to 80 percent.
The current economic recession has left millions of Americans under the impact of sudden loss of employment, now standing at 8.9 percent nationally, resulting in the loss of 5.7 million jobs since the beginning of the recession in December 2007, according to the Bureau of Labor Statistics of the U.S..
“In today’s economy, job loss can happen to anyone,” said Kate Strully, who led the new research as a Robert Wood Johnson Foundation Health and Society Scholar at the Harvard School of Public Health.
We must be aware of the consequences for health caused by the loss of work and do everything possible to alleviate the negative effects. ”
Previous studies have found a relationship between job loss and ill health, indicating that some workers with health problems are more likely to lose their jobs, and the reverse is also true that job loss can lead to certain health problems, said Strully.
Of course, not all health problems are necessarily likely to be caused or aggravated by the loss of work, but the stress related to the situation, increasing the likelihood to be affected, resulting in cases involving the cerebro-vascular accidents, hypertension, heart disease, arthritis, diabetes and emotional resulting in psychiatric problems, according to investigators.
Swine Flu On Facebook
As one of the most important social network in the world today Facebook, could not be alien to the world struggle waged against the scourge of that era is the swine flu, or influenza A, and several groups have originated in function of this struggle.
From Mexico where it all began, were used to cover all media, minute by minute monitoring of the disease, since cases that appear at every turn, until all preventive measures to protect the population and their global spread and immediate intervention by international agencies such as WHO and the UN.
And at such global alarm, social networks could not be exempted because they represent a tool and weight, has to face the struggle for life, and Facebook, if you put the word swine flu in the search, a diversity of groups with ongoing activity, where you can find all kinds of positions, from critics throughout the global development of the disease, its extent in different countries, how each country carries out prevention, and treatment cases.
We can also find groups that posit the most unlikely solutions, such as political relations with reference to bombs and Chavez, as well as those seeking the suspension of international flights to Mexico and the U.S..
Facebook groups are multiplying almost exponentially, and that so far reached 327, referring to the disease, bringing together 15,000 people.
Undoubtedly social networks such as blogs, microblogs, Twitter represents the most important tool for the global fight against latent ability to the feared pandemic, allowing ordinary people to convey their experiences, state or local knowledge, as a new line of defense and perhaps the most powerful.
The flight from loans
Today was published this ANSA:
ANSA - ROMA, 31 OTT - La crisis pushes Italians fleeing from loans and 84% had difficulty to pay the installments. The problems are such that 64% turn rules out new loans and only 8% said they were ready to do it instead. The survey also shows that on average each month comes from the pockets of families 478. The financial crisis has sent up in smoke 17% of investments made and to meet the expenditure, the ’scissors’ crashed on holidays and clothes.
The news is very worrying.
84% have problems in paying their mortgage and therefore the 64% rule out the idea of turning on new loans.
The mouth of families in a little easier, is to think well before you turn on your own mortgage.
The phenomenon brings serious social consequences: it cannot turn mortgage difficult places in the youth in creating their own family.
Also, if two are afraid to tackle such an undertaking, let alone how to see the prospect of living in a home.
Finally to further discourage the hopes for the future there is also a weight s monthly average of 478 and with our average salaries are not few.
The data published by this agency surveys are alarming, the only positive note is a growth slowdown in inflation to 3.5%
Euribor still declining
Comforting news for those who have a mortgage.
The rate at one month Euribor continues to fall and the FBE said that increased from 4.79% to 4.76. The rate for one week but it fell from 3.86% to 3.84%.
This should soon fell influence rate mortgages, making breathing slightly poor Italians with water in my throat.
But in all likelihood will not be such a small percentage change in the Italians call sixthly permanently.
Surely at least Christmas in perspective, if the rates continue to fall, maybe we can afford a gift more.
Credit Crunch in Tuscany
Tuscany is happening close of the credit.
The increase in interest rates and most importantly, the timing of financial confidence has led banks to reassess the criteria scrupulous with each client that requires funding.
According to some surveys, the restriction of funding would be more than 5% compared to 2007.
“The close bank - says Mario Breglia, president of Real Estate Scenarios - particularly affects young people, immigrants and those who have a lower middle income. It should be better for those who want a big house and honor, which pays in cash, and then moves investments from finance to brick”.
So what the Italian has done for several years now back “fashion.”
And if first davamo little importance to savers who invested in the brick, it is time to shake his hand and complimented him.
In a completely unstable people could invest in a house now has its own capital revalued significantly safer and instability of the stock market.
We will see if the close of the claim will result in the rest of Italy or is it just an isolated case.
The Obama emergency plan
Today Obama is the new president of the United States of America.
Last month he made an important speech on the economic situation of the country.
The main points:
“A tax credit for businesses that create jobs in the next two years, eliminating the tax on capital gains for small businesses, the moratorium for three months for those in danger of losing the house for a mortgage is not paid, tax incentives for those who takes the unemployment benefit. With these and several other small practical proposals as to allow the Americans to withdraw money from your retirement fund, Barack Obama yesterday launched the piano relief for the middle class”.
These are the promises for the economic future of American country.
The new “Lincon” (as they called) appears to be directed towards a European type.
The presence of the state is alternating with free enterprise, according to the time loss.
Obama has understood that it will take extensive relations with the continent, seeking an ideal place between the two continents.
After the failure of the planned economic system, also completely capitalist and liberal it is jammed.
This has caused a reversal of the global economic situation.
The ball goes to Europe and to the mixed economic system.
We will see in coming months as the new president wants to relate to the economic crisis that is facing the world and together we can improve our position.
