A weapon against obesity and diabetes

To conduct the study, the scientists examined the effects on obese mice of several apple varieties, including Braeburn, Fuji, Gala's, Golden, McIntosh and Red Delicious (all American while there are many other varieties on the planet). It is the green Granny Smith apple that had the highest rates of the compounds mentioned above.
The researchers emphasize that their findings could prevent many health problems associated with obesity , such as the first signs of diabetes can be reduced by compounds anti-inflammatory of the intestinal flora present in the colon .

"The food we eat determines the balance of the intestinal flora" , said Giuliana Noratto, adding that non-assimilable compounds present in apples even change the composition of bacteria feces of obese mice and make them comparable to mice of normal weight.

The interface will adapt to terminals

The icons or charms bar (right on the picture) bar was one of the new Windows 8 ergonomic proposal that does not meet the membership of users.  According to the latest rumors, it could disappear in the next version of the OS.  © Microsoft

The interface will adapt to terminals

This new Windows, which carries the currently codenamed Threshold ( threshold in English ), should bring many new features and adjustments for Grievance users. Starting with the return of the Start menu is already confirmed by Microsoft. It will adopt a format hybrid , combining the installed programs list in the right column and customizable dynamic tile in the left column. A first image of the new Start menu has recently appeared on the Internet via the forum My Digital Life.

Another change is granted, the ability to make applications of modern classic interface in the environment turn Bureau. But more importantly, Windows Threshold would be able to adapt according to the terminal on which it is installed. This was revealed journalist Mary Jo Foley, Microsoft recognized specialist. On a PC with mouse and keyboard, the OS will run by default on the Windows desktop. On a tablet touch is modern interface will load. Something for everyone and especially Microsoft reconcile with its installed base that has still a majority of PC users ...

Threshold may hold yet more surprises. The latest revelations Site WinBeta , the toolbar (called charms bar in English) could simply disappear. The features of this menu on the right side of the window in Windows 8 will be integrated directly into the Windows interface of modern applications. Another rumor, this time reported by Neowin , on the introduction of virtual desktops through which users can run their applications in different areas while having a unified view. A novelty which really would not be an option since it already exists on Mac OS X and distribution Linux Ubuntu . According to Mary-Jo Foley, a first preview of Threshold would be launched this fall. The opportunity to verify all information and see if Microsoft was able to hear his clients.

Windows, aka Threshold: an update on the new expected

Windows, aka Threshold: an update on the new expected

Microsoft is preparing to release a new version of Windows currently known as Threshold code. This new OS, due out next year, will have the difficult task of erasing the many flaws of Windows 8 which is struggling to attract individuals as well as professionals. The information distilled show that the finalization of this Windows 9 reflects the criticisms leveled at the current system.

One of the major complaints that users have with Windows 8 is the removal of the Start menu.  Microsoft has confirmed that he will return in the next version.  A first image of the new menu has appeared on the Internet a few weeks ago.  © My Digital Life

Windows 8 may well be the operating system of the newest Microsoft (OS), it is not the most popular! According to the latest figures from NetMarketShare , Windows 8 and its update 8.1 cumulative 12.48% market share, far behind the ancestor Windows XP (24.82%) and Windows 7 (51.22%) which is supposed successor (remember that the end of support for Windows 7 is already programmed). Launched in October 2012, the new OS has attempted the challenge of change by removing the Start menu button and the famous Windows and offering two distinct environments.

The first, called modern interface (formerly Metro), is aimed at terminals touchscreen with applications specific presented a mosaic of windows called dynamic tiles . The second environment is the classic Windows desktop that Microsoft wanted to take second place by setting a default boot on modern interface. Result, Windows 8 has baffled users uncomfortable with having to juggle between these two worlds. Companies also shunned the new OS which was not sufficient to justify a transition from Windows 7 or from XP! A fiasco that is reminiscent of Windows Vista ... Sensing the danger, Microsoft has worked to make adjustments for the next version, the output is planned for 2015.

A higher than expected flow of micrometeorites at least 50 times

Before you really begin his harvest of observations that should last until 2019, astronomers and engineers were careful, of course, to check that all was well. However, they found minor disturbances. Despite his visor 10m diameter responsible for maintaining a steady temperature to avoid mechanical deformation may reduce the accuracy of measurements, a light parasite stronger than expected entered the instruments.

The telescope itself expands and contracts from tens of nanometers to more than expected. Finally, small amounts of water that were trapped in the machine before its launch are sublimated in the vacuum of space before condensing on the mirror , again in larger quantities we imagined. The mission itself is not compromised, but it should change the string of measures intended to make the necessary corrections and data taking was therefore postponed, therefore, a few months.

A higher than expected flow of micrometeorites at least 50 times

A surprise was still to go. To achieve its mission, Gaia needs to be pointed very precisely in one direction, which means to know its rotation on itself. Micrometeorite impacts could bias the telescope pointing. Now, from experience with other instruments already joined the L2 Lagrange point , as Planck and Herschel, it was expected to flow micrometeorites impacting Gaia from 1 to 10 per day. Instead, the sensitivity of the instruments showed he was on the order of 500 per day!

According to astronomer Floor van Leeuwen , of the Institute of Astronomy in Cambridge (UK) and member of the responsible cooperation of Gaia, although the origin of these micrometeorites is not yet well established, they could come from a dust ring surrounding the Earth , more or less associated with the Lagrange points. His colleague Nigel Hambly, University of Edinburgh, even think he could be a remnant of the formation of the Earth and the Moon .  Whatever the cause, Gaia is now ready to begin his campaign observations.

Galactic Archaeology and dark matter

Gaia is also designed to identify exoplanets . We think we can make a complete inventory of body type Jupiter in orbit around 200,000 stars closest to the Sun, up from 150 to 200 parsecs and detect thousands of planetary systems by measuring the movements of their star guests . It will also be possible to detect transits planetary photometrically.

With nearly a billion pixels, Gaia features the largest digital camera ever flown in space. The satellite rotates slowly on itself, once every six hours, scanning the sky with both telescopes. It will measure the positions and velocities of distant billion stars in the Milky Way, 30,000 light years away. © Esa, YouTube

Galactic Archaeology and dark matter

Which probably most fascinates astronomers and astrophysicists, is the possibility of the galactic archeology and attempt to better understand the nature of dark matter or disprove its existence directing us to change laws gravitation through Mond.

Indeed, Gaia must measure the positions and velocities of a billion stars in the Milky Way by performing a complete survey of the sky up to magnitude  20. In the same way that a sufficiently accurate throes of the water surface in a pool measure can tell us who jumped, where, when and what side it will be possible to go back in time to experience a part of the history of our Galaxy . How was it formed in accreting matter, such as the dwarf galaxies or current tide of stars torn from previous interactions with larger galaxies. This is one of the questions we hope to answer.

Will it has a dust ring around the Earth?

Will it has a dust ring around the Earth?

The Gaia spacecraft is ready to begin its observations in orbit around the country Lagrange point L2, despite some unforeseen inconveniences which resulted in a delay of a few months. Intended for galactic archeology, she maybe we already revealed a secret history of the solar system. Hit by a number of higher than expected micrometeorites, Gaia could be plunged into a dust ring that surrounds the Earth.

Launched December 19, 2013 by a rocket Soyuz from Kourou in French Guiana, Gaia began his journey to the Lagrange point  L2. With this instrument mainly dedicated to astrometry, a wide variety of results are expected. It can be used to conduct new tests of metric theories of gravitation , as that of general relativity by studying the deflection of light by the gravitational field of the Sun and planets in the Solar System .  can also detect secular variations in the gravitational constant .

Photovoltaic solar energy, how does it work?

This new track brings another benefit: lower cost of manufacture. While solar cells are often made ​​of materials whose manufacture requires a lot of energy (including with silicon), the use of perovskite (a mineral abundant on Earth ) to require much less.

The cells would apply by a method akin to painting a car or graphics printing: the sprayers into several layers. The waste would be minimized. The concept could be easily adapted to mass production and become more accessible.

By replacing the layer absorption of light , essential to any photovoltaic cell , a perovskite form of paint spray, the researchers also improved energy efficiency. "The best yields of organic cells are around 10%. The perovskite cells now have an efficiency of up to 19%. This is not far behind at 25% silicon, the material that dominates the global solar market," says Professor David Lidzey, principal investigator on the project.

Researchers at the University of Sheffield, UK, have developed solar cells perovskite which may apply in the manner of a paint spray . So it would be possible in theory to transform a variety of products and surfaces generating energy. The idea of flexible solar panels is not new but has been slow to materialize.

Many volunteers caregivers worldwide are working alongside health professionals in affected countries. Among them, two Americans were infected with the virus in Liberia . Samaritan's purse, employing the NGO, said they had accepted the administration of the experimental treatment against Ebola  has not yet been tested on humans. This serum, and produced by known ZMapp Mapp Biopharmaceutical San Diego, has been a study of monkeys. The results were promising. Their condition seems to have improved. Since then, Dr. Kent and Nancy Brantly Writebol are treated at Emory University Hospital in Atlanta (USA).

August 5, nearly a thousand patients died of Ebola suites. Many patients are placed in isolation to try to stem the epidemic. A suspected case is currently under review in New York and another in Jeddah, Saudi Arabia. On behalf of Twitter , Gregory Härtl, spokesman of WHO confirmed Tuesday that test results had not yet been issued. Finally, Nigeria, where an American citizen came from Liberia died of the disease last week announced six suspects, all of whom have been in contact with the first victim on the ground.

"What is missing most is the staff who experience the Ebola care " said Dr. William Stephen, physician coordinator of Doctors Without Borders (MSF) to Sierra Leone. First explanation: the number of doctors and experienced in this type of situation nurses is very low. Their training does not include protocols for management of these patients highly contagious . "This disease is rare and has never been observed in this region" , he said. Result, they may not know how to react and protect themselves. Perhaps this is why the number of caregivers contaminated since the beginning of the epidemic is important. They would be sixty according to WHO.

Now - after five months of epidemic in Guinea , "several generations of health professionals have learned how to behave in our structures, especially from their peers who have faced outbreaks in Uganda, for example" . However, "the work is intense and hard, so they must be continually renewed" . Moreover, the spread of the Ebola virus  to new countries, such as Liberia and Sierra Leone neighbors, and spread of cases represent a major obstacle. "The situation is alarming as there are so many cases in so many different places that it's hard to take them all over " , he said.

The Nuclear Safety Authority  announced  that it was "not favorable" to the prosecution after 2015  operation of Osiris reactor.

"ASN is not in favor of continuing the operation of the system OSIRIS beyond 2015 given the current level of safety of the reactor." That's what says the Nuclear Safety Authority (ASN) in its opinion of 25 July 2014 on the continued operation of the BNI 40, called "OSIRIS". This confirms a position already expressed in recent months in technical discussions about this installation.

The problem is the same for bone and renal scintigraphy: technetium is essential.

Eccentric planets

Very good image resolution has also allowed astronomers to measure the misalignment of the two discs that difference exceeds 60 degrees. One of at least two disks does not lie in the orbital plane of the two stars: it has a large gap in this alignment. This information is important because astronomers believe that because of this misalignment, the planets that form are likely to have a very eccentric and highly inclinée.Ce orbit that will not facilitate their detection, a problem qu'auront resolve scientists in a few million years.

Until then, it will look for other factors that might explain the orbital eccentricities of some newly discovered planets. For example, the giant that puts 80,000 years to circle its star ! "The alignment discs defects can not account for all the eccentricity of the orbits of extrasolar planets. All the pieces of the puzzle has not yet been collected, which is a challenge to say the least interesting to meet ! " Eric Jensen concludes.

The images offer a view with a resolution never achieved discs and gases that surround the stars shortly after their birth. It is within the disc of matter will gradually aggregate to form planetesimals and finally of exoplanets .


In the world, the majority of the stars are actually binary systems in which the two bodies rotate around each other. Astronomers have been trying for several years to understand the internal dynamics of these systems and particularly on how planets form inside. For this, it is important to know precisely the characteristics of protoplanetary disks.

With ALMA, the team not only observed the disk surrounding the dimmest star, but also perform for the first time, to determine its speed. "It also appears that the discs have alignment defects" confides Eric Jensen, an astronomer at Swarthmore College in Pennsylvania, USA.

Why Manuel Valls called for a gluten-free diet
ALLERGY OR INTOLERANCE? The first is rare and occurs immediately after ingestion. It is manifested by respiratory and / or digestive and up to cause edema.

Gluten intolerance, or celiac disease, is one of the most common digestive diseases, as we mentioned in the previous article in Sciences et Avenir. It can occur at any time of life. Celiac disease gradually destroys the lining of the small intestine and can have very serious consequences if the patient does not follow a lifelong gluten-free diet. The only known treatment is the total eviction of gluten from the diet.

Anyway here are the foods that are within the scope of a regime without gluten:

How? By transforming the data of the order of eyeglasses in computer algorithms, as well as installing a light filter in front of the screen.  algorithm changed the brightness of each pixel on the screen, creating a sharper image when it reached the retina.

They devised this ingenious method, which is still at the prototype stage, in one study, in which they chose images of hot air balloons in the colors very vivid before distortion.

They found that people with minor vision problems did not perceive these deformations and their image appeared sharp. Indeed, the screen controls the manner in which each light beam emanating from the display.

The researchers also tested their technology using a digital SLR camera Canon and arrived at an equally sharp image without affecting the contrast (photo cons:  © Massachusetts Institute of Technology ).

Only problem seems to be high: how to make this technology fits many people simultaneously watching the same screen?

One of the co-authors believe that the resolution could facilitate simultaneous viewing, but further work on the subject is still needed before considering marketing.

Our statistical intuition is misleading

Our statistical intuition is misleading

First, this reasoning does not take into account either the fact that there is a very large  number of planes taking off every day. Certainly, there is very little chance of dying in a plane crash. But since it is nearly 100,000 flights taking off each day around the world, the probability of a plane crash in the year becomes relatively strong.

Then, another shortcoming of this argument is not to consider the time period in which the proceedings are accidents . Again, the probability that three planes fall this week is tiny. But if the question is asked "what is the probability that 3 planes crashing in the same week for the past 10 years ", the probability rises to ... 60%.

It is very human to imagine a terrible law of series when one is faced with such a series of air disasters. Yet it does not exist, and it is no more dangerous to fly right now in 2013, a record year for air safety.

PERLAN . It's almost a spaceship. The Perlan II, a joint project by the aircraft manufacturer Airbus and the Perlan Project (a group that brings together old drivers) will be the plane that will fly the highest in the sky ... in 2016 hopefully.

Crossing the troposphere and soar into the stratosphere

The future will evolve glider at an altitude of 27 km is in the middle of the stratosphere, the second layer of Earth's atmosphere that extends above the troposphere whose limit was 15 km altitude. So high in the air, the glider will face violent updrafts and as it is expected to do around the world it will also face the polar vortex.

March . In fact, the Perlan II will fly in a similar one would find in the sky of Mars environment. In the stratosphere, the air density reaches just 2% of the density at sea level and it also frois that above the red planet. To keep its lift and maintain flight in this almost empty, the aircraft must travel at high speeds close to those of his or supersonic. The fuselage must be strong enough to withstand the shock waves generated by crossing the sound barrier, yet light enough to fly. The engineers will work on new aerodynamic concepts to overcome these constraints.

According to preliminary information, the Perlan II should weigh 800 pounds in a size of 10 meters long and thirty meters span. In 2006, a version of the glider preière the Perlan I, piloted by Steve Fossett, American businessman and adventurer who has stepped aeronautical feats (man with a round the world non-stop ), beat the world record altitude by up to 15 447 meters.

Ebola is characterized by bleeding, vomiting and diarrhea

Nigeria's Minister of Health, Onyebuchi Chukwu, has assured that the Liberian hospitalized out of a plane from Togo, was not involved in the population and that "all public medical institutions in Nigeria were equipped " .

Ebola. Ebola is characterized by bleeding, vomiting and diarrhea. Its mortality rate can vary from 25 to 90% and there is no licensed vaccine.

The virus is transmitted by direct contact with body fluids and tissues of infected humans or animals.

" Ebola is contagious but can not be transmitted by water or by air. (...) The most important thing to protect is not to touch people with the symptoms, "said Tarik Jasarevic.

He stressed that a "secure burial is essential" because "in many cultures, family members touch the body during funeral rituals. This is when they are infected."

Two groups are most at risk of Ebola infection

READ Ebola: a medical officer catches the virus
"They both receive intensive care, but it is of course a dangerous and scary situation," said the spokesman for the charity Samaritan's Purse, Melissa Strickland, for which the doctor works.

Two groups are most at risk: related (sick) and personal health, "said one spokesman for the WHO, Tarik Jasarevic, currently in Sierra Leone.

According to the WHO , as of July 20, 1093 cases were reported, including 660 deaths. The record was 454 cases and 219 deaths in Sierra Leone, of which 415 314 deaths in Guinea, and 224 127 deaths in Liberia.

On Friday, Nigeria announced that a national of Liberia died of Ebola in Lagos, the largest city in Africa, a megalopolis of 20 million people with sanitation and dilapidated system of health ethics. This is the first reported case in Nigeria (about 180 million), which placed all its ports and airports on alert.

In town or in the countryside, "the answer (medical) is the same: find the people who have been in contact," but "the added difficulty in urban areas is that there are more people, so it's more complicated, "said Tarik Jasarevic.

The nursing staff for ebola infections on the front line

In Freetown, no precautionary action was visible Sunday and apparently indifferent people going about their business, according to an AFP journalist.

At the Department of Health, however, it is ensured that the capital is under increased scrutiny and information campaigns have been intensified. A dedicated processing center Ebola is being installed in the hospital Lakka (western suburbs).

The nursing staff on the front line

On July 23, the ministry had announced that a medical officer of the anti-Ebola center of Kenema, Dr. Omar Khan, was infected. Three nurses at the center have already died of the disease.

Dr Khan, who remains hospitalized, "responds well to treatment," said another official from the Ministry of Health, Abubakarr Fofana.

Two Americans, including a doctor involved in the fight against the epidemic were also infected in neighboring Liberia.

Ebola is getting worse in Africa

The latest report of WHO reported 672 deaths over 1201 cases reported .

The spokesman of the Sierra Leone Ministry of Health, Sidi Yahya Tunis, said Saudatu Koroma, an apprentice hairdresser, 32, died Saturday, July 26 was Ebola.


She had been hospitalized since last Wednesday in the western suburbs of Freetown. But on Friday, "her father and her mother took her by force", prompting authorities to issue warnings of research on television and radio, said Mr. Tunis. This had convinced her to return to the hospital, but she died on the way.

Mr. Tunis, "blood samples taken from the father and mother are being analyzed." The house where she lived in East Freetown, and all its inhabitants were quarantined for 21 days, the maximum incubation period.

The epidemic affected hitherto mainly east of the country, in areas of Kenema and Kailahun.

Objective: To analyze the samples taken from 175 anonymous donors - and hundreds of others in the future may be close - to create a massive database on the human body.

This proposed "Big data" is conducted within Google X, a research division of the Mountain View giant, which has recently  shown  with the contact lens for diabetics.  It confirms the incredible diversity of American society, moreover an area where we do not necessarily expected, his previous retractions instead been made ​​in the field of high-tech and robotics.

DRONES. April 15, 2014, the California firm Google announced the acquisition in fact the manufacturer of drones Solar Titan Aerospace. And in order to use "weather satellites" that conceives this business to make Internet access available in the most remote places on the planet.

As shown in the infographic above, this is not the first time that Google invests in company s manufacturing technology hardware high tech. Since 2006, the Internet giant combines the purchases of companies specializing in robotics and artificial intelligence. And investment were particularly heavy last year.

A story about Nazdana Illness

Other encouraging trials

Since Nazdana, doctors CHA practiced the procedure in five children suffering from the same problem as the small Winnipegger.

Good results encourage Dr. Aneal Khan, who heads research on the experimental treatment, "With the plugin, we noticed that the cells are able to help control the ammonia up to a year and a half after cell transplantation" has he explained the site Ici Radio Canada .

The urea cycle  is a process of converting the ammonia into harmless material, urea, which will pass into the urine and give yellow.
During digestion, the proteins are broken down into amino amino, kinds of building blocks which are transported in the blood and used for the growth and tissue regeneration. Excess protein our body need not go through a transformation process which converts the amino acid into ammonia. But too much of the ammonia quickly becomes toxic to the body. This is where the urea cycle. The liver must allow it to convert toxic ammonia into non-toxic derivative, urea, which is ultimately excreted in the urine.

Canadian Nazdana is Too small for transplantation

Too small for transplantation

Normally, the best treatment is a liver transplant, but Dr. Aneal Khan, a geneticist had found the operation too difficult for a child so small.

In November 2012, the girl had therefore received the first transplant of liver cells from a patient in Canada, Children's Hospital of Alberta (ACH).

Dr. Khan and other doctors had therefore carried out a series of transplants liver cells, including healthy cells used to keep ammonia levels low enough for the baby.

"The transplantation of liver cells in Calgary has given new life to Nazdana and we restored the hope that it will have a healthy future," said his father, Ali Jouhar, site Ici Radio Canada. Her daughter will therefore celebrate its second anniversary in August.

REGISTRY. Nazdana Jan, a little two year old girl born in Winnipeg, Canada and  grafted liver cells just three months after birth is doing well informed H ôpital for Alberta Children where she had been taken into load in November 2012.

The baby was  born in August 2012 with a disorder of the urea cycle, a genetic malfunction that prevents metabolism of ammonia produced by excess protein to be converted by the liver to harmless substance. This condition creates a build up of ammonia which, if left untreated, can cause brain damage or death.

drugs may increase the risk of obesity in adults

"While it is known that these drugs may increase the risk of obesity in adults, it is unknown whether the use of antidepressants during pregnancy increases the risk of women metabolic disorders in their children," said Holloway.

"We have demonstrated for the first time in experiments involving animals, that the use of antidepressants called SSRIs (Selective Serotonin Reuptake Inhibitors), results in increased fat accumulation and inflammation of the liver, raising new concerns about the long-term metabolic complications in children born to mother who took SSRI antidepressants during pregnancy, "said Nicole De Long, who presented the research at a recent meeting of the International Society of Endocrinology and the Endocrine Society.

The researchers stress that pregnant women should not avoid antidepressants during pregnancy, but they and their children should be monitored further to the potential occurrence of diabetes and obesity.

"The benefits from this research is that it can help identify groups of high-risk children who may require special treatment to prevent obesity and type 2 diabetes later in life," said De Long.

Risk Taking Antidepressants By Pregnant Women

Risk Taking Antidepressants By Pregnant Women

Pregnant women who take antidepressants may make their children who were born later had type 2 diabetes and obesity later in life, according to a new study reveals.

The increasing number of type 2 diabetes and obesity in children

antidepressants in the mother pregnant medical researchers at McMaster University, Ontario, Canada, found a correlation between the use of Prozac (fluoxetine) during pregnancy with an increased risk of obesity and diabetes in laboratory studies involving animals. If the relationship is also true for women, it could explain at least one factor contributing to the increased rates of diabetes and obesity in children.

"Obesity and type 2 diabetes in children continues to rise and there is an opinion in which it relates to lifestyle and consumption of high-calorie foods and lack of physical activity. However, our research has found that the use of antidepressants by pregnant women may also be a contributing factor to the obesity and diabetes epidemic, "said researcher Alison Holloway, professor of obstetrics and gynecology at McMaster University. 

apple every morning can also help speed up the body's metabolism

eating Apples
An apple every morning can also help speed up the body's metabolism. This is because apples are rich in pectin which can encourage metabolic process. Eating apples should also be done before a workout for the body to get energy and preventing hunger.

When arriving at the office or work place, stretch your muscles and inhale deeply. Only by stretching arms above the head, slightly rotate the arm, and draw a deep breath can release tension and burn some calories. This in turn will affect your metabolism.

5 Simple Ways to Speed ​​up Metabolism

speed up metabolism body not all people have a good metabolism. Some people have a slow metabolism, and this could also be caused due to genetic factors. However, that does not mean the problem can not be overcome. Recent research even suggests that the body can actually 'tricked' to burn calories more efficiently, especially when you are exercising.

The process of metabolism is essential for the body. At the time of metabolism, some substances are broken down to produce energy for vital processes. While other substances necessary for life will be synthesized. This chemical process is considered important for producing energy and nutrients needed to sustain life.

Simple Ways to Speed ​​up Metabolism

There are some simple ways to speed up your metabolism in the morning, which are:

Exercising will speed up metabolism and burn more calories. This activity is a choice of healthy living throughout the day. When not active, the body tends to prefer sweet foods are high in calories.

Aromatic plants contain natural substances

fennel Sowa
Sowa Fennel contains compounds that are beneficial to the fight against cancer. Called monoterpenes, these compounds stimulate the enzyme, glutathione-S-transferase. This enzyme is a powerful antioxidant that is very effective in targeting different types of carcinogens, particularly free radicals. Sowa Fennel also contains essential oils known to stimulate digestive secretions, activating the production of bile to help healthy bowel function.

Aromatic plants contain natural substances that can stop cancer cells that proliferate in the tumor. Terpenes contained in it is known to contain fatty acids that will make cancer cells die at the end. Cancer research has shown that this plant can be used in conjunction with a number of drugs that can make cancer cells become more friendly to chemotherapy.

Mint leaves
Eat mint leaves help prevent blood supply needed to grow a cancer tumor. Without a source of nutrients, the tumor will eventually die. Mint leaves contain phytochemicals that supply is cut off.

Thyme (Thymus)
Has long been used as a treatment, thyme currently has more than 350 species spread throughout the world. Such as rosemary, thyme contain terpenes. In the case of thyme, terpenes in the form of thymol. In addition to anti-cancer properties, thyme is also an antioxidant, antiseptic, and antibacterial. More than that, thyme has anti-inflammatory properties, so it is very useful to reduce the swelling in the throat and mouth.
