Try to develop a cancer prognosis test

Though they may seem predictable, the paths of scientific research are often surprises. It was what happened to Dr. Mario Galigniana, CONICET researcher in the Department of Biological Chemistry, Faculty of Natural Sciences, UBA, and winner of a Guggenheim Fellowship in 2010, while trying to elucidate the function of a protein discovered recently.

"When I was working in the United States characterized the protein, but had no idea what was in the cell," says the scientist, who was repatriated in 2004 by the Estate Program of the Ministry of Science. "Later, back in Argentina we had a result that surprised us: We found that a protein very similar to that I worked in the United States is located within the mitochondria, a cell organelle. We thought it was a mistake because the technique used, but I found that actually was there. "

The unexpected location of the protein molecule, called FKBP51, led the researcher to immediately reformulate their hypotheses: "We think if it is a mitochondrial protein could be related to programmed cell death processes that are mediated by this organelle."

To test this, decided to study what was happening the cell when this protein is produced in excess: "We proved that over-expression of FKBP51 protects cells from death," he reveals.

As is well known that cell survival is characteristic of tumor cells to Galigniana the next step was obvious: "We looked at twelve different tumor cell types and found that FKBP51 expression is increased in all of them," he confirms. "We also found that if we inhibited the expression of the protein the cell becomes more sensitive to death," he adds.

The results of these studies, which were unveiled at the International Congress of Steroid Hormones and Cancer held in September in Scotland, led the researchers to study the expression of FKBP51 in human tumors.
"In human biopsy samples of various types of tumors we observed the same qualitative and quantitative pattern we saw in tumor cells, suggesting that this protein might be involved in these malignancies," believes Galigniana.

According to the researcher, the specificity of the FKBP51 can think of it as a possible prognostic indicator of cancer. "We are trying to determine if the level of expression of this protein can be used as a marker of prognosis, metastasis, survival and remission, "he says.

For his part, Dr. Elisa Bal, CONICET researcher at the Institute of Oncology Angel Roffo, where human tumors analyzed, said: "We're still getting to know this new molecule that has potential utility. But more studies are basic and subtraction to analyze a larger number of tumors. "

Meanwhile, in the laboratory of Galigniana made progress in the development of a prognostic test to measure the amount of FKBP51 in the blood. "We generated an anti-FKBP51 monoclonal antibody to measure protein by enzyme immunoassay, a method of quantifying very sensitive, and preliminary results were satisfactory territories. But we still need to test human sera and analyze, among other things, reproducibility, specificity, and whether there are interfering substances, "he announces. "If all goes well, only then we can prove it with patients."

A generously sized fruit such as watermelon and low cost of production, keeps in its interior colorado properties than appetizing. Is that the red pigment contains substances that can prevent illness. How can attract given its healthy consumption components?, Argentine investigators were raised and put under the microscope this fruit in order to generate innovative products. Then he began to retrace a line of work: Developing dehydrated watermelon crunchy snacks, that are a healthy treat, "said Dr. Maria del Pilar Buera, from the Laboratory of Physical and Chemical Properties of Biomolecules and Conservation Faculty of Natural Sciences at the University of Buenos Aires (FCEyN-UBA), who directed, along with Dr. Claudio Petriella, the thesis work of Alicia Gallo of the University of Luján, on this issue.

Watermelon, well known by all, was little studied, says Buera, and found that "has a high concentration of lycopene, a carotenoid that is the red pigment characteristic of the watermelon. Lycopene, which became famous in tomatoes, could have an impact in preventing prostate cancer, according to various studies. Is that carotenoids - Buera-points have antioxidant that slows the action of free radicals that can lead to negative consequences. "

Total Eclipse at dawn

Next Tuesday is one day strongly astronomical. On the one hand, at 20.39 hours in Argentina, the sun reaches its maximum southern declination, kicking off the summer in our hemisphere. From the observational point of view that will translate, among other things, that our star will reach as high as possible in our skies at noon, nearly 80 degrees above the horizon for Buenos Aires and surrounding areas. Almost over our heads, and giving rise to very short shadows. On the other hand, and this is what most concerns us here, there will be a total lunar eclipse. And it will be a few hours before, in full morning of Tuesday, our satellite will sink completely into the huge cone of shadow of the Earth. A play of shadows, lights and colors that we enjoy from all over Argentina (and much of the world). No end to end, because we see the beginning of the eclipse, and much of central stage, but not the end, which runs now with the Moon below our horizon. However, miss the second half of the show will, interestingly, a rare prize: to observe the spectacular setting of the Moon red.

Bacteria Found in fossil stromatolites Neuquén Blogs

are the oldest life forms on earth. They are called stromatolites and recorded on our planet for about 3,500 million years. It is laminated structures in which organic matter is bound to minerals, usually calcium carbonate, are attached to the substrate, and are products of the metabolic activity of microorganisms, primarily cyanobacteria. They were responsible for providing oxygen to the atmosphere through the process of photosynthesis, and thus enabled the development of other life forms.

currently living stromatolites are limited to a few places on earth, and it is easier to find them in fossil form. However, in most of the fossil record is difficult to find traces of organisms that gave rise to them. But recently in the western province of Neuquen, stromatolites were found with fossilized algal filaments could be seen under the electron microscope. Trapped in these stromatolites are also nanobacteria. Moreover, we could accurately determine its age: 65 million years.

37 Weeks Pregnant, Sore Throat

Are 12 days sufficient to address climate change? Science

probably need more. Still, this is what has gone on the 2010 climate summit in Cancun. For most, the governments of participating countries reached the "Agreements of Cancun." With this package (accused by many media outlets as "modest" and rejected by the Government of Bolivia ), will attempt to design a "Green Fund" which involves measures for the protection of forests and increasing use of clean energy. Nor is forgotten, protection and assistance to developing countries that do not have sufficient means to combat climate change, and are those most suffering (thanks to the commitment of raising 100 billion dollars annually over the next 10 years.)
These agreements also set the commitment of limiting temperature increase to less than two degrees Celsius .
Still, these documents do not clearly reflect the process of collection, nor the progress of the extension of the principles of the Kyoto Protocol .


However, despite the "fog" of the objectives achieved the summit, the Secretary-General United Nations, Ban Ki-moon , congratulated the government of Mexico for its work and good conduct of the negotiations. In fact, both agree that "these agreements will lead to more effective action against global warming."

Whatever scenario achievement in Cancun, we must also stress that the implementation of the agreements, will be held next year in climate summit to be held in Sudáfric a. They await the development of the "Green Fund" and more restrictive policies for the U.S. and China, among others. But one of the most important aspects of the Summit 2010 (which has not surfaced and are discussed at the next summit), has been the rejection of proposals for small island states who fear their demise by rising sea levels (global warming = melting ice sheets and glaciers, rising sea levels =).



With all this, Cancun has achieved progress on the previous summit in 2009, but still a long way to go if we want this to end and providing a better life to our children.

Climate Summit 2010

these days is taking place in Cancun, Mexico, the "16 th Conference of the Parties to the Framework Convention UN Climate Change (COP16) and the "6 th Conference of the Parties to the Kyoto Protocol, but is best known as the Climate Summit 2010. More specifically, the summit started on 29 November and ends on 10 December.

Here, as in all the 192 member countries discuss climate change with an objective clear: to leave behind the failure of the old last year's summit in Copenhagen (Denmark).
is to create a plan for sustainable development has to be concluded after 2012, the guidelines of the Kyoto Protocol . Among the new targets proposed in the summit, including: reducing carbon emissions (especially in rich countries), provide financial support to developing countries (which are the ones who really suffer the consequences of climate change), combat deforestation and soil degradation ...

On December 10 we will see if you really get a new plan that reflects the reduction of greenhouse gas emissions emissions and no economic gain "certain nations." For now, if you want to be informed about everything that is done, I recommend that you enter on these two pages: one is the official Summit and the other is a blog where every day is information interesting about this event.

And even though it appears on the official website, I'd like to show a video in which well displays the effects of global climate change.

Study finds amniotic fluid cells function like embryonic stem cells vs Chaos

The vast majority of fatal diseases (including cancer) could be solved through treatment with stem cells , which have the capacity to self-renew or differentiate to produce various types of mature tissues and functional. However, there is a major obstacle because of the ethics of extracting them from human embryos, especially by religious organizations (including the fact that such treatments are experimental period .)

All in all, a group of scientists Max Planck Institute of Molecular Genetics of Germany has managed to reduce this barrier, with the discovery of the conversion of cells from amniotic fluid (fluid surrounding the fetus in the womb) in pluripotent stem cells (can not form a body full, but any other cell type and cell lines).

The biggest advantage involving embryonic stem cells is that they have the ability to quickly become any other cell type (such as liver cell, the hair ...), through a process called reprogramming (induction of genes, what to become pluripotent). However, with this research, we discovered that cells extracted from amniotic fluid have the same characteristics that make them into cells with other functions. Furthermore, its extraction is relatively simple, since in the prenatal checkups collect more than necessary. On the other hand, when fresh cells not only have mutations in their genes.

conversion process amniotic cells into other cells. Source: Max Planck Institute.


This group of scientists is deep in research on stem cells, which make large and beneficial results like this. So much so, that their findings have been published in the journal PlosOne .

another teaching tool expands

past two years, Ms. Leila Torres discusses the phenomenon of blogging as an educational resource in middle school. The teacher is part of a project that works under the perspective of "extended school" that aims to achieve digital literacy.

of polytechnic students involved in the proposal created their digital diary to publish their online practices, and so enhance their learning through the administration of new digital tools. These tools allow them to explore fully the new opportunities provided by the network and develop innovative materials from the new languages \u200b\u200bof communication.

The project, called "Education in Times of You Tube, put forward a proposal which is to manage knowledge through the creation and use of websites and blogs. Both teachers and students work daily in the production of materials and its publication. "It is noteworthy that the school's students have Huergo the possibility of free access to internet at school. Before starting this project, they had no knowledge about how arming, designed and produced a blog. The notebooks of the new era will also enable them to create their digital identity, which involves the development of its digital profile, learning new ways to interact and connect with their peers and the world "explained Professor InfoUniversidades Torres.

Bacteria margins Sundial

A team of scientists said yesterday that he had trained a bacteria to eat and grow from a diet of arsenic instead of phosphorus, one of the six elements considered essential for life, "which raises the possibility that there are bodies elsewhere in the universe or even here on Earth, using powers that we had not dared to dream. Microorganisms, obtained from the bottom of Mono Lake, California, and grown for months in a laboratory culture medium containing arsenic, phosphorus atoms gradually traded in their tiny bodies by arsenic atoms.

The scientists said these findings, if confirmed, will expand the notion of what life might be like. "There is a basic mystery when you look at life," said Dimitar Sasselov, an astronomer at the Center Harvard-Smithsonian Center for Astrophysics and director of an institute that studies the origins of life, which is not connected with work. Nature uses only a very restricted set of molecules and chemical reactions among the thousands that are available. This is the first sign that there might be other options. "

Matias Zaldarriaga

With less than 40 years, the physicist who graduated from Matias Zaldarriaga Exact-UBA has an outstanding scientific career. Ph.D. in physics at MIT 15 years ago living in the United States. He currently works in Princeton, where he sought to unravel the details of the Big Bang. Many point out as a future candidate for the Nobel. Visiting the College, as guest lecturer at the Physics Department, spoke to the Cable.


By Gabriel Stekolschik

- Your job is rather solitary?

- No, in general work with others. But I like when you can work in smaller groups. If you have to handle very large groups you end up making bureaucracy. Escribiendogrants (N.de R.: Order of subsidies), correcting how they wrote the papers. In short, doing things that are not as cute. I did not get to do escribirgrants physical, so I try to avoid that. So if I can stay in a tiny group, for which I need not raise money, I'm happier. Now I'm part of an experiment to try to fly a balloon from Antarctica to measure cosmic background radiation. It is a large group of people there and I do a minimal role. I tried to do some things, but I threw well, because it is much talk on the phone and turns into a job.

- not like work ...

- (Laughs) I like to think. It is much easier than you can think of an idea to invent something. But then when they do, it takes many years. And it's boring because you know that is something that will probably work, but in the middle is a lot of problems, collect the money, make grants, managing students and posdocs ... a job is done. I like doing things theoretical.

- Yours is basically "paper and pencil?

- Yes I sometimes work using data from a telescope. But often even use data. For example, I am interested in inventing what kind of measurement, what kind of telescope should be done. Then I do not. Or, if I interpret results from observations of someone who grabbed the data, reduced, removed something and I make a model to explain it. And sometimes I accounts that are not directly related to the outcome of an experiment, but with a future experiment that might do or not.

- What excites you most?

- Almost always there is a specific question about me is excited at a time and generally has to do with threads coming out of this group of four or five posdocs who work with me. In recent years, were things about Inflation Theory, the principle of the Big Bang, and the different observations can be made. Ways to make bills that had not been made and that sort of thing.

- and out of physics what you love?

- My family especially, because apart from work is more time as I am. With my daughters and my wife.

- Any hobby?

- I have. I like to run. I will run almost every day. Would run the entire marathon in Philadelphia, but eventually I will run only half. I have two daughters, little girls and I have to work so it's a matter of finding the time. When I have time, go out and run. Sometimes it's an hour, sometimes two.

- What do you think while running in Theory?

- (Smiles) Sure, yes. That is the best. Nobody bothers me. Because when I'm in the office, although I try not to have to work, come and ask me. And in my home I have a girl of 2 and 4, so it is impossible to do anything. I will end destroyed. I used to work at night, now reaching eight in the evening and do not want to do anything else. I can answer emails, things that do not require thinking, more bureaucratic. So when I run I can think of many things. There I have an hour a day, at least where I can do what I want.

- Did you meet their own limits to achieve a result?

- Things I can not solve? A lot.

- Do you consider the possibility of a Nobel?

- The odds of winning the Nobel I are very low. They may be higher than others, but they are super low. In other words, not think about it. Besides, the Nobel always give it to the old. There are exceptions, but often give it to people who are closer to ... no? (Laughs). Besides, most of the time they give for making any remark, and I did not comment.

- Making observations is part of the work that you do not like ...

- (Laughs) Yes, it's part of the work that I do not like. It's like teaching, I like to teach, but then when I have to prepare for class, there is always another thing I'm making beats. The same thing happens to work, to do experiments. At first I was amused, but they become very large and is, as I said, a lot of talk on the phone, to handle things in management.

- Are you consistent in your theoretical developments or like to nibble on different issues?

- more or less constant. I did four or five different themes but in which I was working many years. No I like to do very cortitos papers of different things all the time. But there comes a time when there are already many people working on the same thing and is more difficult than you can think of something to do. So there I start thinking about something else. Because when it gets crowded very difficult to compete, there are some who are very good. And sometimes I let things that are not filled because I was bored before. If I look back, I can see what he was doing four years ago and I was bored.

The math would predict the collapse of the courts


The news released in recent weeks about the danger of collapse of the Buenos Aires courts, like the courts pension houses in Marcelo T. de Alvear 1800, offer an incredible illustration of the nightmarish atmosphere recreated in his novels Franz Kafka.
With 35,000 new lawsuits per year and 400,000 cases awaiting resolution, the accumulated paper weight dangerously threatens to exceed the limit of 270 kg (sic *), according to the National Institute of Industrial Technology, should not transgress if it is to keep safe the integrity buildings.
But it's impossible to stop the feverish input files (not even won a three-week fair court authorized to request the courts), Mr. Ricardo Miró, mathematician "resident" of the judiciary, has just developed a system that would a warning for months or years before reaching this terminal crisis.
"You are four times when court buildings are collapsing under the weight of accumulated papers, has looked. I was working for the past five years on this issue and developed a series of algorithms that would anticipate this sort of" tsunami 'judicial. "

. Cosmos

science here and there, but ... Do you know what is its origin? When the universe began to see how a cluster of unexplained events?

all goes back to the 6th century BC in Greece. There, a group of scientists, among whom were Thales Empedocles and concluded that the universe was knowable and had an order and some regularities, that is, that nature worked around a set of rules, and not because of the "gods." This was the first major conflict between science and mysticism, and change from chaos to cosmos, or whatever it is, began to see the world as a set of events predictable, orderly and harmonious (cosmos), leaving the view of the unpredictable and unknown (chaos).

For you to understand better what I have said, here I leave a documentary Carl Sagan (1934-1996 New York), physicist and doctor in astronomy and astrophysics. This chapter corresponds to the television series Cosmos , issued in 1979.

Time magazine publishes a list of the 50 best inventions of 2010


month and a half left to finalize 2010, and with it comes the wave of lists of the best and the worst of the year. So Time magazine has not been left behind and has published a list of top 50 inventions this year.

Among them auto car drove Google , the iPad , the Chinese bus passes over vehicles, the bionic exoskeleton that allows a person in a wheelchair may take a few steps, the synthetic cell Craig Venter (a bacterium with significance for future vaccines), the laboratory-generated lungs (which would solve the problems caused by the transplants) and the glasses that let you draw or write following the movement of the eyes ( EyeWriter ).

Chinese Bus, and cell bionic exoskeleton Craig Venter / ABC

All these scientific and technological inventions are great improvements in research and development. The fact that a magazine Time published the relevance of these items, assist in the dissemination of the idea it all comes down to science.

Side Effects Of Sweet N Low?

Can you predict the future? The art of disseminating

Telepathy, prophecy, clairvoyance, precognition ... all these concepts hint at knowledge or discovery of the future. The possibility of "guessing" coming events has always been, and is, an enigma and a desire for the human race. Because of all this are the numerous historical documents, film libraries ( Back to the Future) and novels ( The Time Machine) that address this issue.


Today, thanks to advances in science, research on these phenomena are more effective. An example is the study by Daryl Bem , a psychologist at Cornell University (New York), which states the possible evidence that the future can be known and that the events occurred can not influence the behavior of human.

Bem has researched this issue for eight years, which has conducted nine experiments to 1,000 student volunteers.

In one of these experiments, showed his "guinea pigs" a list of words and asked to recall those that might. Later, students had to draw up a list of words that had memorized while a computer did the same at random. The experiment is surprising that the vast majority of words in the lists of volunteers matched those he had chosen the software.
Another experiment showed was that a computer screen which featured an image with two curtains, and were told they had to guess what was hidden erotic position. This study was repeated 36 times for each individual (the placement of the image was random) and consisted of 100 sessions, in which, 53% of students chose the correct shade (for the pure chance is expected to 50%) .
In the third study, the psychologist, spent the test in which a word is displayed first (usually "ugly" or "beautiful") and then a picture unpleasant or pleasant, with a view that the individual decides whether the photograph is "ugly" or "pretty" (in many cases are "flashed" with a word something that was otherwise so that the person will cost you to decide). Well, what he did was teach Bem first photo and then thought to ask what word would appear (again, was chosen by chance.)

In this experiment, Bem did observe evidence of psi (paranormal phenomena, by which the individual has the ability to acquire information through senses other than those already known - "sixth sense "-).

However, like everything related to parapsychology, this issue is very controversial. On the one hand, it is to publish an article with the results of this experiment in the journal Journal of Personality and Social Psychology , supported by the head of the editorial, Charles Judd. But on the other hand, this study has not convinced many scientists, Joachim Krueger and psychologist who has dismissed as "ridiculous."

If you are interested in this subject and I want to continue to report, there is a blog that posted a very interesting entry on precognition and its origins. It presents several interesting anecdotes. The blog is called cosmic Island and you can see the entry by clicking HERE.

Biodegradable plastic / Award for Argentine forward

A biodegradable film made from renewable, non toxic, low cost and with multiple applications in the packaging industry, which was drafted by a team of Argentine scientists, won the distinction for best project in the area of \u200b\u200bproducts and services from Latin American Awards for Innovation and Entrepreneurship.
"We are very proud that they were competing with countries that are very strong in technological innovation such as Spain, Brazil and Mexico," said Dr. Silvia Goyanes and Mirta Aranguren, directors of the project that emerged as a collaboration between the Laboratory of Polymers and Composites, Department of Physics, Faculty of Natural Sciences at the University of Buenos Aires, and the group of Intema Ecomaterials, Faculty of Engineering of the Universidad Nacional de Mar del Plata.

The prize, worth 20,000 euros, will be presented at the Iberoamerican Summit to be held in Mar de Plata, 3 and 4 December.

This plastic film is part of the new trend of packaging "green" to "allow the reduction of solid waste and thus generate positive impacts on the environment, unlike traditional packaging, which are made from nonrenewable resource degradation difficult, "says the official statement from the jury.

Translucent, odorless and tasteless, this material meets the requirements demanded by the markets of Europe and the United States." If the film is buried away in a week and has no toxicity. It is very friendly to the environment, "said Goyal.

White Initiation Dresses 2010



"The rigor in science journalism is increasing, is making its way into society, becoming a necessity." This is how Professor Manuel Lozano Leyva has inaugurated the series of lectures and activities that the cicCartuja has prepared for the Science Week 2010 (see previous post). It also cited the radio as the best means of scientific publication.

In his lecture titled Ten discoveries that changed the world view , which students have attended the School of Communication, presented the ten most important scientific discoveries (personally) of the universe. It has done so in a meaningful way: reducing scale from highest to lowest, ie the galaxies started and ended at zero and infinitesimal.

also worth noting here that Lozano is not only a great physicist, but also a great promoter (currently participating in the program's scientific gathering A life that are two days of in Montserrat Domínguez Cadena SER , and made several informative lectures and conferences like this, not to mention more curriculum-).

Ten discoveries that have reported are:

Milky

1 . Galaxies are the basic pillars of the universe and the stars.
here talks about the discoveries of Galileo , Kant and Hubble , among others. The latter who first discovered the telescope that bears his name.




2. Plate tectonics.
This theory equivalent to quantum mechanics because it explains everything (in this case the geological phenomena).

3. The origin of species.
The natural selection was discovered by Darwin and Wallace (independently) and was a breakthrough in the process of understanding the living (then there was the theory of Lamarck ).

4. The blood circulation.
This discovery made the medicine go from being an art to a science.

blood circulation



5. The Rosetta stone .
When Napoleon invaded Alexandria, he found this stone, which meant a breakthrough in the humanities, was the first language dictionary.

6. Microorganisms.
With the discovery of these, it was research in the field of disease (among other matters).





7. Genes (Discrete changes). With
Mendel and peas, we now understand the complex science of DNA.

8. Atoms.
According to Lozano, the atoms assume a probability distribution of presence.

9. The symmetry in the microcosm.
The discovery of symmetry at the microscopic scale, assumes that there is something rather than nothing.

10. From zero to infinitesimal.
Zero is nothing. The infinitesimal is the difference between nothing and a little (as little as you like, but non-zero).

Unfortunately I can not dwell on this interesting conference, but I can say goodbye the same way as it has Lozano Leyva: with a quote from Napoleon (1980).

do not know a better way of living to devote to know the nature.

Diazapam 5 Mg Tablet Myl



Rest on a good pillow and mattress "warm" and will not be as beneficial, especially if the material thereof are feathers ave.

According to a study, 360 patients, led by Ferran Morell, (head of the pulmonology of Hospital Universitario Vall d 'Hebron ), with the collaboration of researcher Ana Villar, this may be the cause of pulmonary fibrosis. Also investigated the phenomenon in Japan and the Netherlands.
This chronic respiratory disease (which can cause death) is characterized by scarring or thickening of the lungs (become rigid). Occurs because small pockets of air in the lungs become scarred; causing not enough oxygen reaches the blood.
The strange thing about this anomaly is that its causes are unknown, so it's a disease called "idiopathic."

usually occurs in people over 40 years and some of its symptoms are dry cough, chest pain, decreased tolerance to the sport, breathing difficulties and abnormal sounds within the body (like when removed the "velcro"). Patients with advanced disease often have a bluish (cyanosis) around the mouth or fingernails, and an abnormal enlargement of the fingertips.

Lung fibrosis

order not to leave the track and continue with the investigations, it has adopted an FIS predoctoral fellowship to this group of scientists.

On the other hand, medical solutions eradicate pulmonary fibrosis are still under study. However, the Guild of Naturists in Peru, based on bioenergy and alternative medicine have proposed natural medicines (herbs from Peru) as Namu, the Toxola, Jelly Toxola and as a regenerator, the Ananiper. They also use the magnet to increase exercise capacity, improving quality of life of patients.
