Menthol cigarettes quickly addictive



The cooling flavor menthol cigarettes causes faster drug addiction. Doctors have found the body of smokers prefer menthol cigarettes with additives, and gets more nicotine and carbon monoxide.

Even if a person smokes fewer cigarettes per day, menthol contributes to the development thrust to "nicotine stick" because of what was expected of such a tobacco product is twice more difficult to refuse.

Because mentholated cigarettes are much harder to quit, and most quickly can become a chronic smoker. That menthol is not only enjoyable, refreshing and harmless ingredient in cigarettes: a substance masks the negative properties of nicotine and toxins, and develops a lethal addiction to tobacco products. Presumably, the "guilt" of menthol is in its aroma and taste.


Depression and smoking are related genetically:

Chromosome that carries the genes of depression, and were able to link depression to smoking. Analyzed 800 families from the United Kingdom, and the Americans have collected statistics for 91 Australian and 25 Finnish families. At least two close relatives of each family have suffered from periodic bouts of depression.

That depression in families, and attachment to nicotine is often go hand in hand. Smokers with this nervous disorder often try to quit, but they returned to smoking. That the third chromosome region, covering about 90 genes linked depression to smoking.

The plot of the chromosome known as the place of localization of glutamate receptor metabotropicheskogo. This type of membrane receptor, which in nerve cells react to the presence of the neurotransmitter glutamate in the synaptic cleft between neurons. It is believed that this receptor protein is involved in the formation of chronic depression.

Trust but verify


No pills to treat hyperactive children tablets only in extreme cases. One of the main problems of treatment - is the ease with which doctors prescribe antipsychotics or other psychotropic drugs, and how many parents meekly agrees.

Drug treatment - an extreme measure. If parents do not want their children to become guinea pigs, let them know what treat this disorder, If your child is prescribed a drug that is not in this document are not too lazy to even score in the Internet search engine's name.

Another problem - expensive drugs. In Ukraine, the treatment course of methylphenidate - first-line drugs for medical treatment of ADHD - cost about 1500-2000 USD.

In Europe, available cheaper drugs, a monthly treatment that costs less than EUR 50. The State does not solve the problem by force, so as usual, all hope for enthusiasts. For children with development Inna Sergienko opened several weeks ago. While here only four children, but all comers.

7-year-old Zhenya Hyperactivity Disorder - one of the first pupils of the school-garden. Just came from a walk, where long jump with a rope, but with pleasure on the big swings the ball, then flops into the pool, filled with colored balls of soft plastic.

After that, begin classes: reading, math, art lessons. For each child in school must have at least one teacher - speech therapist, psychologist, speech pathologists, an art therapist, igroterapevt, logoritmist.

Psychologist Tatiana Pears, head of the Center for Applied Psychology Pyrus, working with children, including those with hyperactive, over 15 years. These children can not long hold the attention on one thing, so at the beginning of therapy sessions carry individually.

Drawing, Lepim of plasticine. Gradually, these guys are diligent, accustomed to the daily routine and rules of conduct. But without parental support here is not enough.

Free radicals do not cause aging :



It is generally accepted that free radicals cause aging, and antioxidant, inhibiting the reactivity of these molecules, in contrast, slow process. Are part of the normal stress response of the body and have beneficial effects on certain levels.

Maybe the reason for the correlation between free radicals and aging due to the fact that their appearance in the mitochondria caused by a reaction to the damage caused by the aging process. With their help, the body tries to fight.

Specialists also offer a partial explanation of the usefulness of physical exercise: they lead to a slight increase in the level of reactive oxygen species.

In addition, researchers suspect that the positive effect of moderate alcohol consumption does not come from oxidants in red wine, but because of the mild oxidative stress caused by drink.

This does not mean that free radicals are useful. They are beneficial to health only at normal levels, and in case of severe stress or progressive disease caused their harm exceeds the benefit.

That reactive oxygen species contribute to the progression of cancer and neurodegenerative diseases, despite the positive effect on the lower levels. They are also the cause of wrinkles on the skin.

The mechanism by which free radicals prolong life, remains unknown.
New point of view, casts doubt on the idea of antioxidant pills, which should slow down the aging process and protect against disease. "If we carry out clinical trials of this drug no effect will be.

Information on the Internet :


Finding information on the Internet to prevent senile dementia :

Scientists have found that regular search of some information on the World Wide Web are able to stimulate brain activity and potentially slow down, if not prevent, its decline associated with aging, which may develop into dementia.

With the help of magnetic resonance scanners that can detect brain processes, the researchers found that "the Internet stimulates the brain more than reading, and the effects of its influence still remain long after the Internet session." ITAR-TASS.

Depth and duration of effect they attributed to the fact that the user has to perform several tasks at once - keep in mind important information by focusing simultaneously on the contents of the screen, take the text and graphics.

As a result of observing the influence of online operations for brain activity in volunteers aged 55 to 78 years, scientists also concluded that searches on the Internet can be an affordable form of exercise for the brain, which increase cognitive abilities of older persons.

The brain is like a muscle - the more his training these, the healthier it becomes," - concluded they are.

Lack of Internet provokes stress :

Without access to the internet, people feel more anxious. About this analysts say the company Future Laboratory

According to a survey company, the lack of mobile communication and contact with relatives through the Internet causes stress for 36% of respondents, while 29% said that in such circumstances, they feel more freely.

Identified two new types of consumers, "off"and "included". That people are included" type "knows that in today's world no one is waiting and the lack of communication can knock you out of rhythm. The number of people expressed the need for the Internet grew by 7%.
