It is possible to determine the geographic origin of beer

|

(www.neomundo.com.ar/_SINC) “the differentiation of the beer according to its origin can be using parameters related to its raw materials, such as water (metals and anions) and the type of hops (content in polyphenols)”, explains José Marcos jury, chemist at the University of Seville and director of a research to know the origin of the beers.

The first step is to select variables most distinctive beers, such as the amount of strontium, aluminium, iron, for example through a statistical test. Then applies another mathematical analysis to eliminate those parameters that do not discriminate well the origin of beverages, and the result is a model based on the content of iron, potassium, phosphorus, phosphates and polyphenols.

“Differences may seem subtle, but the model is capable of finding the relationship between these chemical descriptors and the geographical origin of the beers,” says jury. The last step is to apply “support vector machines”, a set of algorithms that recognize patterns in the data

Researchers have applied this technique to differentiate beers produced in Germany, Spain or Portugal and have managed to know which country they come from with 99.3% of effectiveness, according to the results published in the journal Food Control.

“This type of study can be extended to other geographical areas, but must take into account that to expand the number of classes obtaining an appropriate model is complicated”, clarifies jury. “Differentiation must be addressed considering large areas and studying a posteriori possible groupings that appear less large areas”.

Identification for the food industry

Studies of authenticity or geographical identification are “very important” in the food industry, according to the investigator, “since they allow establishing differentiating characteristics of the products, which can affect your marketing”.

PREVIOUS Chavez returns to scene with an American Summit without us

|

CARACAS (Reuters) – the President of Venezuela, Hugo Chavez, will return to monopolize the regional scene five months after having been operated from cancer, at a summit which will bring together 33 American leaders to establish a body that does not have been invited United States and Canada.

The appointment on 2 and 3 December in Caracas of the community of Latin American countries and Caribbean (CELAC), named by many as “an OAS without Washington”, will be a test of the health of the controversial Socialist leader, whose disease came to raise doubts about his candidacy for re-election in 2012.

“This is the first time that Chávez is displayed to all peers regional since that was diagnosed with cancer and, as always, you’ll want to look good on the big stage,” said a diplomatic high European.

Military retired 57-year-old insists that it is fully healed after the surgery in Cuba to remove a tumor, the later four cycles of chemotherapy and a scrupulous monitoring of medical advice, and moderating his Marathon speeches and order its chaotic pace of work.

However, cancer specialists say that they must spend years before to ensure that it has overcome the disease.

Speculation about the political future of the Bolivarian leader have not ceased since the Chavez was forced to cancel the original quote from the CELAC, scheduled for the 200th anniversary of the independence of Venezuela 5-6 July, after being operated emergency in La Habana.

Venezuela, for its part, opposition denounces Chavez used his role as host in these international summits to expand its influence international with the country’s oil and divert attention from internal problems and spread his famous slogans UN-American.

“The problem for Venezuelans is that at the end of show, your visit will serve to legitimize and consolidate this autocracy,” wrote the opposing political analyst Rocío San Miguel in an open letter to the delegations of the CELAC.

Another acronym MAS

Analysts believe that the regional meeting is an unbeatable opportunity to show Chavez his meteoric recovery, but many doubt that the CELAC will go beyond the symbolic aspect and go to swell the bulky list of projects for complex integration latinoamericana.

“Is another regional club more, but it reflects something important and profound: a sense of sovereignty and independence of Washington which has been brewing for some time”, said Michael Shifter of the Inter-American Dialogue.

“The question is what the CELAC of other regional mechanisms that already exist will differ and whether it will produce something really effective and concrete”, added.

Like other efforts of dialogue, such as ALADI, Mercosur, CAN, ALBA, Caricom or Unasur, this new instance has the challenge of bringing together wills in a region with enormous economic, geopolitical and social gaps of mistrust and friction bilateral.

In Caracas, however, Queen optimism about the event, which will feature the presence of the Brazil, Dilma Rousseff; Moyne and Argentina, Cristina Fernández; as well as the heads of State of Colombia, Juan Manuel Santos, and Peru, Ollanta Humala, among others.

“This is something historical” in truth (…) “It is a first step, is not the victory, but it is a first step because since the 1800s began the (independence) bid on this continent,” said Chavez recently behind the creation of the Agency.

The discussion will include the creation of a common fund of reserves to deal with the financial turmoil of the West and the formation of a human rights body alternative to the Organization of American States (OAS).

Although some worry that Chavez and his leftist allies try to inflame the Summit with rhetorical “anti-imperialist”, it seems that the large presence of conservative and centrist Governments will give way to a more moderate speech to avoid pronouncing directly against Washington and the OAS.

“The more we integrate, more will be prepared for the hurricane that is experiencing the world economy and the instability of the rest of the planet.” “Why give you so much importance to this Summit,” said the Colombian President Santos, United States close ally in the region

All eyes will be on the actions of Chávez as master of ceremonies, who will also chair a parallel Summit of the Union of South American Nations (Unasur) and another of PetroCaribe, an agreement that Venezuela sells crude under preferential terms to allies of the Caribbean and Central America.

Look at the legs to see if there is a problem in the heart

|

(www.neomundo.com.ar) the State of the legs can be an important indicator of health as people who suffer from peripheral arterial disease have one increased risk of attack heart.

Such a warning was presented by the Vascular Disease Foundation (Foundation for the vascular diseases) of United States, which recommended to be very alert to the symptoms of this condition to make a medical consultation nor well arise.

Peripheral VASCULAR disease

Peripheral vascular disease occurs when narrows the blood vessels located outside of the heart. This happens because a plate of fat and cholesterol, which reduces the space through which the blood flows forms in the vessel wall. As a smaller circulation reaches the legs, usually feel pain and numbness.

The main risk factor for this disease is having passed the 50 years, but the danger increases if a person smokes, suffered a coronary heart disease or stroke, and diabetes or hypertension.

Peripheral arterial disease can study for a while without giving signs of existence, but the most common symptoms are fatigue, numbness in the legs, cramps, pain and wounds in the legs takes to heal. In more severe cases crashes the movement and this results in the death of tissues, a condition which in turn can lead to amputation.

“Too often, people think that a discomfort in the leg or a wound that heals slowly are part of normal aging, but can be signs of a very serious pathology.” “Through the early detection and proper treatment, can reduce the devastating consequences of peripheral arterial disease and improve the cardiovascular health of the population in general,” said Joseph Caporusso, a specialist of the Foundation.

Moreover, the health professionals warned that if a person has arteries blocked in one part of the body most likely have vessels in other regions with the same complication, including those that are located in the heart and therefore increase the risk of developing heart attacks, heart disease and even death.

South Africa launches new campaign to lower rate HIV infection

|

Cape (Reuters) – South Africa town wants that its

rate of new HIV-infected get off at least at 50 by

cent in the next five years and this will attempt to improve

its recent achievements, after years of failure to control the

AIDS and the increase in mortality, said Thursday the

President Jacob Zuma.

Former President Thabo Mbeki was criticised for not taking

serious AIDS epidemic, leaving South Africa with one of

the largest populations of infected with HIV in the world.

But since then, the country has achieved some successes with

a reduction of 50 per cent in the transmission of HIV from

mothers to children between 2008 and 2010 due to improved access to drug

antiretroviral drugs.

More than 13 million people became the controls of the

virus since April of the year after a rigorous campaign

Government.

“Have achieved many successes in the fight against HIV and

“”

AIDS, in South Africa and globally”, said Zuma before launching

the second plan AIDS will be developed between 2012 and 2016.

The National Strategic Plan, among other goals, seeks

reduce new infections with HIV at least by half,

lowering the number of people affected by tuberculosis (TB) and deaths

related to this disease in a similar percentage and have

at least 80 percent of eligible patients for

treatment with antiretroviral drugs.

“We cannot afford to treat HIV and TB form

“”

separated”, Zuma said, adding that the new emphasis, non-existent

in the previous campaign is in great need due to the high

rate of co-infection of the two diseases.

The new plan also identifies sexual violence and the

intimidation of women as a key factor in the

spread of HIV/AIDS.

“South Africa recent research show that we can

“

preventing HIV infection if young women are not

“

subject to violence or intimidation on the part of their partners”,

said Zuma.

Eliminate the bacteria H. pylori alleviate indigestion

|

New YORK (Reuters Health) – eradicate the bacteria H.

pylori would provide some relief to people with indigestion,

even if they do not have detectable, ulcers, he suggested a new

study.

For people which changes do not work you in

lifestyle, how to modify your diet, exercise and

reduce stress, Brazilian researchers now suggest

test with a combination of antacid drugs and

antibiotics.

Experts randomly allocated 404 patients with dyspepsia

functional (indigestion) to a group that received only omeprazole or

to another that joined the drug antibiotics amoxicillin and

clarithromycin, during 10 days.

A year later, 49 per cent of patients in the

cohort treated with antibiotics said that their symptoms had

improved at least 50 per cent, compared with a 37 by

percent among people in the group control.

According to a report on the study of the team of Dr. Luiz

Edmundo Mazzoleni, of the Hospital de Clínicas of Porto Alegre in

Brazil, eight patients would have to be treated with

antibiotics so that a patient experience this type of

improvement.

Previous studies threw mixed conclusions about the

effect of eradicating the H. pylori, which affects half of the

world population, according to the authors of the research,

published in Archives of Internal Medicine.

While their findings come only from a hospital, and by

therefore may not be universal, suggest controlling the

the presence of the bacteria and treat it in people who have

stomach pain and not have ulcer.

However, the authors urged that occur more

studies to know if the strategy is feasible in terms of

cost and effectiveness.

In an editorial, Dr. Paul Moayyedi, the McMaster

University in Hamilton, Canada, indicates that there is now evidence

strong that to eradicate the H. pylori can help a small

Group of patients.

“The challenge will be to establish the mechanism that underlies this

“

effect in order to move forward and try to better our patients

“

with this condition common and costly”, concluded Moayyedi.
