Stress is also caused by work!

Occupational stress is a risk factor for myocardial infarction, but ranges from this point of view, after smoking and obesity, according passionsante.be.

Several previous studies have dealt with the relationship between job stress and coronary accidents. All concluded that a link exists, but differ from one another extent of the risk. A team of British scientists from University College London has reviewed about 15 studies on the subject in Europe, then synthesizing the results.
The data considered were related, in total, about 200,000 people (equal number of women and men) who completed questionnaires specific professional environment, position held and exposure to work-related stress. Coronary home accidents were analyzed in terms of working conditions. 'There is a link between occupational stress and risk of a coronary event, "said Robert Hayat. The risk increases by 23% if work is carried out with stress. Dr Hayat however noted that "the risk is lower than that related to smoking, abdominal obesity or sedentary 'classical cardiovascular risk factors. In other words, 'any preventive measure to combat work-related stress is welcome', without neglecting concern for conventional risk factors.

It was discovered the largest black hole

It was discovered the largest black hole

Astronomers say they have discovered the largest black hole ever observed that a genuine "monster" with a mass of 17 billion times that of the Sun, which is at the center of distant galaxies.

This huge black hole is 14% of the total mass of its galaxy, unlike the 0.1% recorded usually in other galaxies. Is a rate so high that it could compel specialists to review their theories about the formation of galaxies.

Huge black hole in NGC 1277 is located 220 million light-years from Earth, in a galaxy 10 times smaller than the Milky Way. Diameter black hole is huge, being 11 times greater than Neptune's orbit around the Sun.

"It's really an unusual galaxy," said in a statement Karl Gebhardt of the University of Texas at Austin American city.


"It's almost entirely a black hole. Could be the first object found in a new class, the galactic black holes," added the researcher, co-author of the study, published Wednesday in the British journal Nature.

NGC 1277 is certainly occupy at least the second-largest black holes identified and has a real chance to actually be in first place in the ranking.

Mass black hole considered current Number 1, discovered in 2011, has not yet been calculated accurately - it could be between 6 and 37 billion times the mass of the Sun.

Black holes are the most powerful forces in the universe, creating a gravitational field so intense that even light can not escape them.

A stellar mass black hole is formed when a star collapses very big inside her, towards the end of his life. Black hole can continue to grow, engulfing other stars and merging with other black holes, leading sometimes these supermassive black holes that occupy the centers of galaxies.

But NGC 1277 questions this theory by disproportionate to its size galaxy belongs.

Further studies will be necessary to determine whether the abnormally large black hole is unique in its own way or if it actually reveals a mechanism yet unknown cosmic training.

"Galaxy which hosts the black hole seems to have formed as a result of over 8 billion years old and it does not seem to have changed much since then," said researchers at the Max Planck Institute, study coordinators.

Zymafluor treatment is continuous - not interrupted once started it can cause unpleasant side effects such as dental fluorosis.

Dental fluorosis in children

Fluorosis occurs after exposure to high levels of fluoride during enamel formation and is characterized by hipomineralizarea surface layer of enamel. Changes increased in severity with increasing fluoride levels. Dental fluorosis occurs only during tooth formation - that while they do not yet erupted on the arch, so at younger ages 8 years. After the teeth have erupted developed and they can not be affected by fluorosis.

To prevent overdosing is very important to know the level of fluoride in drinking water and in table salt. Must also be evaluated and other fluoride sources including diet.

How our country the amount of fluoride in drinking water and mineral water is negligible / undetectable and as there is no food sold with added fluoride then the risk of overdose is very small.

Toothpaste started to be used since i 500 Hours, both in India and in China. However, at that time, toothpaste does not describe the product you use all day, which was invented only in the 1800s. In 1824, a dentist named Peabody was the first to add soap to toothpaste composition, and in 1850, John Harris has used chalk as an ingredient.

Two decades later, in 1873, Colgate toothpaste began to mass commercialization of container used is at the moment a jar. Only in 1892, Dr. Washington Sheffield of Connecticut chose to use a collapsible tube as toothpaste container. Colgate was not late to take the idea doctor said, so in 1896, it produced toothpaste was sold in collapsible tubes similar to those of Sheffield.

After the Second World War, progress in synthetic detergents have facilitated the soap in toothpaste composition to be replaced with agents based emulsifiers sodium.
A few years later, Colgate started using fluoride as an ingredient.

Did you know ...?

The oldest recipe for toothpaste dating from 400 BC and was discovered in ancient Egypt, was written by a scribe on a parchment sheet. The document is now in a Viennese museum. According to him, for a perfectly clean teeth were needed: 1/100 ounce of rock salt, 2/100 ounce of mint, 1/100 ounce of dried iris flower and 20 grains of pepper.

History of orthodontics

History of orthodontics

Straightening teeth, namely by tooth extraction which helps proper alignment of the teeth was practiced since ancient times, although the branch of dentistry orthodontics appeared only in the 1880s.

According to the American Association of Orthodontists (AAO), archaeologists discovered the mummified bodies of ancient people who were raw metal bands around the teeth, and the Etruscans were buried still wearing the devices used in life to prevent damage teeth and teeth change position. Also, the findings made by a researcher in a Roman tomb in Egypt show some teeth bound with gold wire - the first document of a link.

However, in terms of appearance and evolution of orthodontics, great discoveries came later, around 1800, the credit from many people who have left their mark on the progress of dentistry.
History of orthodontics
First, we should mention the "father of dentistry," Pierre Fauchard (photo), who in his work from 1728 - "Surgeon Dentist" - devote an entire chapter methods of straightening teeth. Fauchard used for straightening teeth a device called "bandits", a piece of precious metal horseshoe shaped what was intended to expand the maxillary arch.

A few years later, in 1757, French dentist Bourdet in turn published a book, "The Art dentist", of which a section was reserved for ways to correct alignment of teeth and also devices used for this purpose. Bourdet, dentist king of France, has perfected the "band" of the Fauchard, being the first premolars extraction recommended to correct "clutter" that has been scientifically proven teeth and jaw growth.
History of orthodontics
Scottish surgeon John Hunter wrote, among other works, "The natural history of teeth" (1771) and "practical treatise on diseases of the teeth," describing in detail the anatomy of the tooth, or dental pathology. He was the one who coined the term "cusp," "bicuspid" "incisive" and "molar."

In 1819, Delebarre introduced in practice clasp wire straightening teeth, and in 1841, Joachim Lafoulon coined the term "orthodontics."

Historians believe that the title "father of orthodontics" to be offered so Norman W. Kingsley, a dentist, sculptor, writer and artist, author of "Treatise on jaw abnormalities" (1880), and JN Farrar, author of two books "Treatise on dental irregularities and ways of correcting teeth." Latter owe the invention of braces, he was also the first to suggest the use of pressure on the teeth at regular intervals to straighten.

Another leading figure in the evolution of orthodontics is Edward H. Angle (1855-1930), who developed the first classification system for malocclusions, a system that is used today. System or offer dentists a simple way to describe how crooked teeth are, what direction they are pointing and how they are arranged in the oral cavity. All Angle is one who, in 1901, founded the first school of orthodontics and organized the American Society of Orthodontics, which became the American Association of Orthodontics in 1930.
In the early 1900s, Orthodontists using gold, platinum, steel, silver, rubber (sometimes wood, ivory, zinc, copper and brass) to manufacture ligatures, hooks and loops used to straighten teeth. The most commonly used was gold (from 14 to 18 carats) due to its malleability. Were made of gold wires, ligatures, clips, while the iridium-platinum alloy sheets were made braces that were fixed on maxillary arch. Gold teeth straightening devices are wrapped around each tooth individually.

In 1929 the first commission was established specialist orthodontic American Commission and the late 1930s, was invented toothbrush with nylon bristles ('38) and stainless steel throughout the '40s began to be used scale. However, using this alloy braces was controversial, being fully accepted in the 1960s.

Before we get to the inventor of Invisalign, braces device "invisible"-should I mention in this History of orthodontics and Dr. New York SC Barnum, who invented the rubber dam (rubber wrap that is used to isolate teeth when a dental), Eugene Solomon Talbot's (1847-1924), who first used radiographs in orthodontics and Calvin S. Case, the first person who used rubber elastic braces.

As braces "invisible," its inventor is Zia Chishti, along with business partner, Kelsey Wirth, founded Align Technology company in 1997, the company manufactures and markets Invisalign appliances. They were sold for the first time in May 2000.
