Information on the science of Melanin - Professional Look
Current info about Information on the science of Melanin is not always the easiest thing to locate. Fortunately, this report includes the latest Information on the science of Melanin info available.When most people think of Information on the science of Melanin, what comes to mind is usually basic information that's not particularly interesting or beneficial. But there's a lot more to Information on the science of Melanin than just the basics.
You should be able to find several indispensable facts about Information on the science of Melanin in the following paragraphs. If there's at least one fact you didn't know before, imagine the difference it might make. And the topic of Information on the science of Melanin is no exception.
Recently, reports have emerged on the practical use of synthetic, and melanin ekstragirovannyh melanin in medicine, cosmetology, and, thanks to their semiconductor properties, in the technology and electronics. Synthetic and semi melanin technologically very dear and Information on the science of Melanin. They are used mainly as an active component Information on the science of Melanin ointments and creams. Melanin allocated from microorganisms melanin, mushrooms and dark grapes, show similar characteristics to animals Information on the science of Melanin. These began with melanin successfully applied abroad for treatment Information on the science of Melanin different etiology, poisonings, radiation losses, alcoholism, drug addiction, AIDS, Parkinson's disease, Alzheimer disease, malignant neoplasms, etc.
However, as shown great number of studies, pharmacological importance it melanin animal origin. Because of the complexity of the selection, clearance of the protein impurities, and the high cost of their practical use has been difficult. So far, scientists around the world have tried to develop technology to Information on the science of Melanin clean. But it managed to do in Russia-initiative group of scientists under the leadership of General Kolesova GN This melanine in quality and efficiency in the tens of thousands times bigger than even Information on the science of Melanin Western samples that have already recognized testing laboratories in Information on the science of Melanin, Monaco, Germany and Japan.
Information on the science of Melanin illustrate the effectiveness of Russian can be a simple example of the pre-research with the use of strict regimes of radiation experimental animals. In the experiment involved three groups of laboratory rats. The first group-the control. The second group has been subjected to stringent Information on the science of Melanin in subletalnoy dose. The third group inside imposed Information on the science of Melanin have eumelanin and, as in the second group. Rats of all groups are equal in terms of content, have an age, weight, sex and female were at half-week pregnancy. As a result, three months after the second group of animals were killed, along with the offspring, and the third group, together with its healthy generation has no pathological changes in all organs and tissues, and that's good for her distinguished even from the reference group.

Melanin is a special pigment that gives the skin and hair its natural color. It makes the skin tanned, but also produces unwanted freckles, birthmarks and other colored marks on the body.Information on the science of Melanin - More Details
With humans melanin forms in special sea-star shaped cells called melanocytes in the basal layer of epidermis and then transforms into granules where pigments are combined with protein. Melanocytes inject melanin grains into the cells of the upper skin layer (cortical layer of the hair and the iris of the eye) and determine their color.Information on the science of Melanin - Doctors view
Doctors from time to time state that tea, coffee, chocolate and cacao are harmful for our health. However, it is no good to give up these products once and for all as they contain melanin that is essential for the human organism. Also prunes, bilberry or dark grapes are good protection against cancer, sunburns and influence of radiation.Information on the science of Melanin - Pre-testing has shown that melanin is universal and effective tread upon exposure to the organism external and internal factors Information on the science of Melanin and carcinogenic nature. Melanin These properties make it an indispensable component of pharmaceuticals protection of the population from the cargo genetic problems in subsequent generations and the bad treatment of a number of diseases in the recent past. This is the new generation of pharmaceuticals melanin series, and the effectiveness of a range of actions which may be subsequently replaced by the great variety of chemical drugs.
Information on the science of Melanin - Another soft-UV light source is our Sun. The sun emits significant quantities and the most stringent UF-luchi that kill all life. Protects us to the Earth's atmosphere. As a result, prior to the Earth's surface never rises rays with a wavelength of less than 286 nm. In reality, in the temperate latitudes of the Earth's surface is not light with a wavelength of less than 295 nm (in Moscow less than 301 nm). So to get a good tan, and do not need a smooth ride to the south of the median strip. Indeed, in temperate latitudes share of soft solar UV light is much higher than anywhere in the Caucasus. Why are rarely sunburn. True, suntan requires long, but he kept much longer than bronze, Southern.
In the mountains, with the rise in every 100 m total UF-radiatsii intensity increases by 3-4%, and mainly through the hard radiation. Therefore, the solar radiation at high altitudes dangerous, and primarily affects the eyes: they are especially sensitive to UV light, which is the occasion of heavy can even lead to blindness. At the other extreme, in the north, for example, has the latitude to St. Petersburg from 15 October to 15 March-night "biological": rays that can cause Information on the science of Melanin, in the period did not reach the Earth. Muscovites denied natural UV light two winter months. In the tropics, the other problem protect themselves from the harmful actions of excess radiation.
If UF-radiatsii high level (for example, in bright sunny summer day), direct pigmentation (by the action of UV) do not manage to protect the skin, so tirozinaza activated enzyme, which "runs" other biochemical mechanism pigmentation (by the action of UVB ), the effectiveness of which is significantly higher.

Information on the science of Melanin - Good Hair
Having a good hair day doesn’t just happen by chance. It happens when taking care of your hair becomes just as important as taking care of your skin. But what do you do when your hair has been damaged by every day styling, and chemical processing, dyeing or perming? Is there any solution for fly-away hair, dullness and faded color?Information on the science of Melanin - Science view
The color of hair is determined by the amount of melanin in the cortical layer. Dark hair has a lot of pigment while fair hair has fewer granules that are of smaller size. Diffusive or non-granulated melanin makes the hair red. Hair, like any other part of the body, requires essentials nutrients for growth and survival.
Information on the science of Melanin - Good Skin
When summer looms, many people start considering the best way to get that sun-bronzed glow — turning to self-tanners, tanning booths, a stretch in the sun, or a combination of these.Information on the science of Melanin - Science view
But before you go into a tanning booth — spend a few minutes finding out about your skin and sun exposure. These facts can help you get the look you want without stressing your skin.Information on the science of Melanin - More Details
Melanin is the body's way of protecting skin from burning. Darker-skinned people tan more deeply than lighter-skinned people because their melanocytes produce more melanin. But just because a person doesn't burn does not mean that he or she is also protected against skin cancer and other problems.Information on the science of Melanin - See more

Effects of light on the various chemical compounds heavily dependent on the wavelength. Leather rights in this respect is not an exception. Experimentally skin sensitivity to determine the time required for the appearance of the first signs of melanin. The dependence of the sensitivity of the skin Wavelength not smooth-there are two "hump" in areas with a maximum of UV and UF-S. This is because the rays with certain wave length diuretic layer absorbed by the skin, as well as those present in the cells of the skin protein. Effects of light in these maximums vary. Thus, when exposures in the area UF-S much less than the threshold dose, that is, the minimum dose, which causes skin redness. Information on the science of Melanin while also less redness appears fast, but fast disappearing. Therefore UF-S exposure in the area (such light gives low-pressure mercury lamp) easily cause erythema, but it is not too painful, as the need for sensitivity burns very large dose. The exception is the eye - they are dangerous even small doses of UV light, they cause after a while intolerable pain, and the feeling is, as if the eye hit the sand. Repeated exposure may even lead to cataracts. Therefore, in the highlands, where the proportion of the UV light more need dark glasses to protect their eyes. The average strip and even on the Black Sea beach hard UV light (Area C) in solar radiation, it can not only provide artificial sources. Skin erythema is, basically, in the UVB rays, and they are already with a small overdose cause injury.Information on the science of Melanin - Tan naturally tend to be associated with erythema: first red skin, and only then skin. However, in order to get, not necessarily "first" to be burnt. If exposure occurs small doses (below threshold) for days, you can not do to bring the skin redness and get all the same. It is important that the body accustomed to solar radiation, so biodoza-minimum exposure that causes lung and skin redness painless, gradually increasing from day to day. Defensive reaction of the skin is so great that time, the appearance of erythema may increase from one minute to several hours, there were even cases tysyachekratnogo reduce sensitivity to UV-B radiation Most people erythema legitimate becomes tan with a soft-UV light exposure occurs direct pigmentation. Such people about 75%, with a certain caution, they can get without having received burns. Another group (about 10%), people with higher sensitivity to the solar beam. Usually, they pale skin, often with freckles. Threshold time, the appearance of erythema very little for them, hence it is difficult to sunbath. Finally, the third group (about 15%) are people with very Information on the science of Melanin skin. They need not fear especially scorching sun, as the skin Information on the science of Melanin they did without redness.
This is the best scheme for tanning: must start from about 1 / 4 - 1 / 2 erythemic and then gradually increase sun exposure time to 2 - 4 biodoz. The average strip in bright unclouded day zagorayuschy biodozu one person receives approximately one hour at a height of the sun above the horizon 54 °. But at Yalta or the height of melanin sun 62-63 ° this time is reduced to 20 minutes. Note that biodoza for every human individual. If desired, it is easy to determine experimentally. This is the time necessary for the emergence of mild redness, it depends on the terrain, weather and time of day.
Tan is possible and when scattered radiation. Navy blue sky and the red sun at twilight attributed scattering of sunlight in the atmosphere, with less than a wavelength, the more scattering. The most powerful it will be precisely to ultraviolet rays. When the sun rises over the horizon of not more than 54 °, solar radiation scattered in more UV light than in the direct beam. Morning and night, spring and autumn in the northern part of a useful UV light comes almost exclusively through the scattered radiation of the celestial sphere. Clouds delay only direct rays. Scattered radiation passes through them almost unhindered. Thus, in order to obtain the minimum dose required for the health of the UV light, more must be kept outdoors, especially without worrying about the fall whether to direct sunlight skin.
But to get tan and not necessarily bother to hell under the hot rays of the sun, it is sufficient if a significant portion of the celestial sphere is not melanin such as a house or a dense forest. Ideal conditions of shade-tree standing alone in a public place in a bright summer day (or shade of a small trailer on the beach sun), in these circumstances Information on the science of Melanin increases 2-3 times, respectively, and the longer the time tanning, but it will be painless.

Sun creams natural mechanisms should help to clear dangerous ultraviolet radiation quanta. This assistance may be purely mechanical: compounds such as zinc oxide or titanium, formed opaque layer, which reflects and dispels ultraviolet radiation. The composition creams also introduce specially synthesized organic compounds, which absorb solar radiation in the desired range of wavelengths. It molekuly-zaschitniki should not feel themselves with the formation of photochemical transformations photolysis harmful products, such as free radicals. Light excited molecule must quickly return from the state of the main proceeding, then again molecule capable of absorbing quantum radiation, etc. Of course, to the substance in the composition of sun creams and impose other requirements: they must be non-toxic, should not irritate the skin.Information on the science of Melanin - All compounds that meet these requirements provide benzolnye ring system involving many ties. This ensures an efficient absorption of ultraviolet radiation. The first of these compounds, found practical applications, was para-melanin acid (PABK). Interestingly, it has biological activity and visibility is a factor in the growth of microorganisms, as well as Information on the science of Melanin substance; one of its derivatives-folic acid (vitamin H). Esters PABK (ethyl, propilovy, Isopropyl) used in medicine as Information on the science of Melanin funds. One of the most famous derivatives-Novocaine.
A more Information on the science of Melanin effective broadcasts korichnoy acid S6N5-SN = SN-SOON and salicylic acid derivative benzofenona S6N5-SO-S6N5. All of these compounds are well soluble in nepolyarnyh environments and effectively protect the skin from ultraviolet radiation, including the facial area. Another important feature of these compounds - strong light absorption is achieved at low concentrations. Quantify the protective effect of the compounds, or songs expressing the so-called "protective" factor. He is viewed depends on the minimum dose of radiation that causes redness (erythema) protected skin to the radiation dose that caused the same clean skin redness. For example, if the skin erythema at the net came after 10 minutes of exposure, and the protected (in the same exact conditions), an hour later, the protective factor is 6. Common admission enhance protective factors - simultaneous application of cream in one of two or more different compounds.
Now you can understand why there's a growing interest in Information on the science of Melanin. When people start looking for more information about Information on the science of Melanin, you'll be in a position to meet their needs.
