Cleo resume activity 1000, the first digital audiometer built in Peru

technology health service has always led to improved patient care and in some cases, find the cure to diseases that have plagued mankind. Although in our country's scientific research has not progressed at an accelerated pace in recent years is commendable efforts are already bearing fruit.

This is the case of CLEO 1000, the first audiometer Digital built by a Peruvian company (now only imported medical equipment in the country), which unlike conventional audiometers, has a higher percentage of software in its composition (30% 70% hardware and software), a feature that allows for more precision, dynamism and efficiency into the system.

CLEO 1000 was developed in the Bioengineering Laboratory Lolimsa company, and is a project which included the contribution of the Peruvian State through the Fund for Science and Technology (FYNCT), whose total investment reached S /. 1 '500, 000, of which S /. FINCYT 600 000 came from. Gustavo

Astorquiza

As indicated, engineer in charge of product development "this audiometer is capable of emitting predetermined frequencies, unlike those that are purely hardware audiometers, where the frequencies are established and there is little ability to vary them." That is, you can almost instantly create new audiometric tests Â-according to the medical necessity of frequencies that can be scaled with differences of 1 hertz. "He can not make any other audiometer in the market. The conventional reach resolutions to differences of 100 hertz or maybe more, but can not make more specific ranges."

Why is better the greater dynamism that allows CLEO 1000? Through the audiometer hearing is measured from the patient and establish what are the ranges and specific parameters that must be headphones for people with hearing impairments. With the dynamism of the digital audiometer, you get a better consolidation of parameters to adjust the hearing aid patients. Technological intelligence

Using the software, which is supported by the audiometer, you can develop some kind of intelligence based on audiometric information. And is that the results of audiometry are incorporated into the medical records of patients in real time, allowing the development of a database to collect all data of a patient, and a group of patients given area.

This allows more easily audiometric information specific groups, grouped by location, gender, or comorbidities. In that sense, CLEO 1000 can be the basis for advanced audiometric investigations.

Milestone in medical technology Peruvian

Why develop a digital audiometer in Peru marks a milestone in medical technology in the country? As noted by Rolando Liendo, chief executive of Lolimsa, "only 0.15% of GDP in Peru is intended for investment in technology, while that in the whole region (South America), the figure is 1% of GDP, and Europe to 2% of GDP. "And in our country, to say the executive," there is no medical technology, much less hardware, all medical equipment is imported.

In that sense Lolimsa bet with the CLEO 1000, seeks to promote the development of medical technology in the country, and encourage similar initiatives.

Lolimsa is a company with a internationally renowned in the health sector. Its technology solutions belong to the ERP2: specialized and targeted for hospital management, pharmaceutical, and medical laboratories. has been install its technology solutions in 10 countries in Latin America, including hospitals, clinics, medical centers, chain pharmacies and clinical laboratories.

2008 was inaugurated bioengineering where production began medical equipment which is completely managed by software. Audiometers, spirometers and simulators for first aid, are the first teams in production.

The company is certified CMMI Level 3 and has been recertified to ISO 9001:2000 as much as 7 times.

Pioneer project studies the effects of metals on the health of children

A total of 450 schools in Elche participated in a pioneering project in Spain, developed by the Generalitat Valenciana, to ascertain the incidence of exposure to metals such as mercury, lead, manganese, health of children.

Studies on mercury, lead and manganese indicate that exposure to them can be the source of several diseases, such as attention deficit, decreased retention capacity and memory, motor deficits or alterations in the growth and development, particularly in pediatric populations.

The Higher School of Public Health Research (CSISP) under the Department of Health, made this work, called Environmental Exposure Biomarkers in collaboration with the Institute of Bioengineering, University Miguel Hernández (UMH) of Elche.

The program, whose final results will be announced later this year, will be extended to other areas of the Comunitat Valenciana to get the full regional map, which is expected to study in 500 children.

To work samples were obtained through the multi-element chemical analysis of hair, with high sensitivity techniques.

In total we have analyzed the existence of 29 elements, both nutritionally valuable minerals and pollutants, most notably arsenic or heavy metals such as cadmium, lead, chromium, toxic, or nickel, related to allergies.

origin sources of these metals may be different from the consumption of fish or milk to mining or industrial environment. We have also studied substances needed in the diet, such as iron or zinc.

Chief Environmental Health of the Department of Health, José Vicente Martí, explained that the main objective of this work is to promote 'a program that would enable exposure school daily to these metals' and the health of the population connected to the environment.

The study coordinator, Professor of the Institute of Bioengineering at the UMH, Eugenio Vilanova, has indicated that the project has been possible to establish the distribution curves of these elements in the school population, particularly in children aged 3 and 12 years.

The relationship between the level of exposure to metals and damage to health depends on variables that determine the concentrations of pollutants in each person, such as age, sex, geographic location or lifestyle.

Each particular item has toxicological own and not all are harmful.

'Moreover, the animal body depends on and needs of specific quantities of certain minerals for its proper functioning, which are also the subject of this study of biomarkers in hair,' said Vilanova.

However, prolonged exposure to certain metals such as lead can cause irreversible changes in brain architecture and cognitive functions.

'It is shown that in young children, chronic lead poisoning may cause disturbances with aggressive behavior and developmental regression, "according to the expert.

Microalgae Biotechnology

Yucatan's coast could be used for the study of phytoplankton, and from this produce biodiesel and bioethanol Photo: Darkroom File

Vice President of the Mexican Society of Biotechnology and Bioengineering, Alfredo Martinez announced studies to take advantage of microalgae oil from the Yucatan Peninsula in the production of biofuels. He highlighted the commitment
Mexican scientists in the development and use of biofuels in different plant species without the use of food derivatives such as corn.
"There is a national consensus not to use food for biofuels, since they do not want a food crisis," he said.

Under the fourth Regional Congress of Biotechnology and Bioengineering West emphasized that Mexico's geographic location allows the generation of different plant species produce natural fuels, clean.
Yucatan For its coast may be used for the study of phytoplankton, according to their feasibility produce biodiesel and bioethanol products in the near future replace the oil and its derivatives.

fuels made from phytoplankton emerge as an alternative to biofuels such as ethanol, recently identified as one of those responsible for the global food crisis.
For this reason, the Mexican researchers agreed to use other species native to the country for the development of these products and avoid the use of edible species.
said the United States will continue with studies in maize, due to surplus production, mainly for animal feed, yellow type, and in the case of white guy, human consumption but for them there is a food.

Meanwhile, Brazil has the right conditions for growing sugar cane for the production of millions of gallons of biofuels and, in the case of Mexico, and is investigated with species such as pine nuts or castor oil, in northern country, while focusing on the phytoplankton.
"Mexico has an untapped potential species useful for the production of energy alternatives, which can take from 10 percent to completely," he said during his conference supported by the Instituto Tecnológico de Mérida (ITM).

energy properties in the field Cuban

Cuban biotechnology has much to talk about recently. Released information about clinical trials conducted in a vaccine against AIDS, getting another one for hepatitis B and various achievements in biomedicine recombinant island have put the country on the map of scientific innovation. However, the impact around the agricultural sector is little discussed, despite having also great advances that have affected local and international level. Cuban biotechnology has much to talk about recently. Released information about clinical trials conducted in a vaccine against AIDS, getting another one for hepatitis B and various achievements in biomedicine recombinant island have put the country on the map of scientific innovation. However, the impact around the agricultural sector is little discussed, despite having also great advances that have affected local and international level.

regard, the former technical secretary of the National Agricultural Biotechnology Cuba, Dr. Maria Cristina Perez Peñaranda, said in an interview that the development of the Cuban countryside has been achieved in part by scientific advances in biotechnology, ranging from fertilizers and pesticides home breeding or biological to advanced techniques in the micropropagation of plants of agricultural interest. "Biotechnology can help a lot to our country, since they will have experts ready and has an integration of the various fields of science and social actors are immersed in the issues that concerns this branch, "she explained.

In this context, referred to Cuban research in biotechnology are approved by a committee tester, which assesses, among other factors, whether there is a niche market worldwide for the proposed development. "So do not call the science and technology programs, but science and innovation, because they are projects that we know we can patent and make a profit for the country field. In addition, biotechnology products for the domestic market are free, and export is the way in which our investment is recovered scientific. "

Peñaranda Perez said another reason that has driven the development of biotechnology exponentially over the past two decades on the island is the entrenched culture linked with scientists, helping to optimize resources to projects. Indeed, they have managed to combine at the Centre for Genetic Engineering and Biotechnology various branches of the area (animal, plant and care), because they understand that each can complement the other and thus extrapolate the results. Also formed a scientific center in the city of Havana, where up to eight instances related to the accelerated development biotechnology.

As for the impact that this branch of knowledge for farmers, Cuba, the researcher said that they have found the benefit to the production of biotech seeds, noting that currently the country has a comprehensive management program biological media related to fertilization and pest control.

Finally, he acknowledged that while the infrastructure is somewhat limited, the strength of Cuban biotechnology holds in its human resources, which are formed in different lines of research related to biotechnology, and are considered as priorities for the country. "In the first year of college youth are subjects related to the subject, but from the second science student groups are formed, while research institutes working in the training of teachers and doctors, "he said.

More applications for biomedical sensors

say that the human body is the most perfect machine ever devised. Understanding the mechanisms and circuits, making use and repair of electronics and other techniques is the goal of biomedical engineers.

One of the most promising fields of biomedical engineering focuses on the development of sensors and instrumentation, applicable to the clinic, in very different conditions and processes. This has been evident in the round table dedicated to this area during the XXVI Annual Congress of the English Biomedical Engineering Society, held on Valladolid.

The first of the works on display responds to the argument that measure the electrical impedance can assess cardiac rejection in transplant patients. This research, by Javier Rosell, Technical University of Catalonia, is based on the assumption that "the rejection edema and destruction of the cell membrane, thus changing the electrical impedance detectable by a electrocatheter.

would be possible to replace the standard method, since it is highly invasive endomyocardial biopsy, to one that is "to analyze the level of rejection through intracardiac catheters, with the advantage that the diagnosis can be made real-time ". But this method is still" somewhat invasive and very expensive. "

are therefore working on a technique more economical, easier and not have to be used, for example, a catheterization laboratory.

So introducing an esophageal electrode may lead to the esophagus to "spend a large amount of current across the ventricular zone."

Other work on the electrical impedance has been described by Benjamin Sanchez of the Universidad Politécnica de Cataluña. In his presentation has been shown that bilateral multiseno signals quasi-logarithmic (BQL) can characterize dynamic biological systems better than other biomedical in nature.

Sanchez explained that "it is necessary to use signal bursts large bandwidth to characterize, with a single shot, the entire impedance spectrum." This will avoid the effects of modulation induced in the impedance caused by the mechanical movement of dynamic biological tissue under study. According to this improvement BQL signal "the signal to noise frequencies of interest without rise to nerve stimulation."

also in vivo characterization of myocardium to detect rejection by esophageal catheter and in vitro of artificial tissue, derived from stem cells to regenerate myocardial tissue are some of their applications.

optimal electrode design that captures the bioelectrical activity generated in the abdominal cavity is the goal of this work at the same table by Javier Garcia-Casado, Polytechnic University of Valencia. Even without conclusive results, this study is based on the characterization sensitivity of Laplacian electrodes since, which has been expressed García-Casado, "registration allows us to reject the tangential components of electrical sources that reach the surface of the body and focuses the vertical components."


Another eye movements of the proposals is the Jazz Novo Sensor, a user-centered development and disability specialist, minimally invasive, easily configurable, enabling multimodal registration, and high sampling frequency catch the eye movement. Joaquin Roca-Gonzalez of the Universidad Politécnica de Cartagena, has introduced this new device that would allow assessment of cognitive functions to improve diagnosis and personalize the therapeutic approach of children with learning difficulties. The

hardware, based on a "very light unit which is registered as glasses, is a multi system which checks the implementation of evidence presented by different stimulation paradigms. As pointed out by Roca-González, "A virtual instrument was designed for exploitation, so that the program can see what is attracting the user and performs the presentation of these paradigms. They are also developing work to study the complexity of eye movement for detecting changes in reading ability.

Eduardo Lage, Experimental Medicine Unit of Hospital Gregorio Marañón, Madrid, has launched a multi-modality tomograph (VrPET / CT) for laboratory animals, cheaper "but that keeps the machine performance within reasonable margins ".

This has reduced the number of CT detectors and not using a complete ring, "reducing the cost in detectors and electronics." Thus, we have developed a commercial PET-CT system for in vivo studies with laboratory rodents very useful "for the development of new drugs in biomedical research basic. "

The U.S. designed a new telecare system for patients renal

Nefrotel

The project would be able to detect and correct real-time therapies and hemodialysis patient

SEVILLA, 13 (EUROPA PRESS)

Biomedical Engineering Group, Department of Systems Engineering and Automation from the School of Engineering, University of Sevilla is investigating a new paradigm applied telecare patients with chronic renal failure.

jobs, according to Europa Press sources of Seville, are part of the Nefrotel project, which aims to provide medical equipment and a more complete update on the health of the patient, and to optimize functions of the telemonitoring.

The system design is based on information technologies and communications and includes new methods and multiscale computational modeling technology. From a technical standpoint, Nefrotel is an architecture that connects patients and healthcare professionals that are organized around different scenarios: the patient's home, the data center provider, resources and services and the peripheral hospital or care.

A Real Time

The objectives of the project Nefrotel emphasizes the generation and integration of custom multi-scale clinical knowledge in real time, incorporating information from the molecular to the systemic level. As a result you can achieve immediate detection of failure, both the patient and therapeutic devices and the ability to forecast and real-time modification of renal replacement therapy.

Laura María Roa Romero, project leader and professor at the School Of Civil Engineering, told Europa Press that "though there are biocompatible dialyzers, patients need a safe and reliable external care, especially if we consider that the renal failure have a multitude of changes."

The project lead to significant savings of time and money to reverse welfare for the patient, "says Laura María Roa. This would value through the decentralization process of the medical center, which would be carried out dialysis in the same household with a direct contact with professionals.

Another Nefrotel objectives is to provide the universal access patient Telecare service which is independent of technology. To this end we have defined a multi-tier architecture, distributed and standards-based, which ensures a connection from the different scenarios with priority control, and security features, reliability and privacy to be required to exchange and processing of such information sensitive. The architectural design is oriented on reusability, interoperability, and scalability of their resources.

A robot mimics the actions of the poodles

Its creators hope it could help blind people who have no dog.

A group of engineers at Georgia Tech have developed a robot that is able to mimic the same actions as does a guide dog to help its owner in the daily work. Users verbally ordered the robot the task you need, and the robot responds after a laser pointer has indicated the location of the desired action. The robot was able to open a door or carry objects from one place to another. According to its creators, this development may be a small revolution, as the demand for guide dogs is greater than supply and the cost is around 16,000 euros. The new generation of robots can be an affordable option for people with disabilities who have no option have one of these dogs.

Guide dogs, an essential tool to provide services to visually impaired people, have inspired a group of engineers at Georgia Tech to develop a robot to copy the actions and movements of these dogs that both enhance the quality of life for the blind.

Although the cost of these dogs is around $ 16,000 (and two years of training to get to perform their skills), demand far greater than the dogs that are actually available.

But what if their functions were performed by an electronic companion equally efficient, but much more affordable?

Researchers at the Georgia Institute of Technology have developed a robot to copy the actions of these dogs. Users verbally ordered the robot the task they need, and the robot responds after a laser pointer has indicated the location of the desired action.

For example, if a person needs to take an object, usually order the guide dog with a gesture that is directed to where the object is located. The robot mimics the process, but the gesture is replaced by a laser pointer directed at the required location. First actions



According to its creators, the technology allows and perform basic actions, like opening a door or take a medicine.

"It's a way to get the robots help people as soon as possible," said Professor Charlie Kemp , Department of Biomedical Engineering, Georgia Tech, in a statement . "The dogs have a long history of helping people, but waiting lists to get one of these animals for years. Is expensive to have. We believe that robots could meet the same needs. "

Kemp presented his findings recently at the IEEE / RAS-EMBS International Conference on Biomedical Robotics and Biomechatronics.

Kemp and student Hai Nguyen have done this project with a team of dog trainers to investigate the different categories of commands and interactions in the relationship established between a person and a dog.

Specifically, they studied the behavioral patterns of Betty, a Golden Retriever. One of the keys to the success of this project was the fact that this dog knew to open and close a door handle being covered with a cloth or towel. The robot was programmed to use the towel or rag in the same way you did Betty.

A revolution?

Trainers who have worked with Kemp and his team have been very surprised with the behavior of the robot.

"The waiting list stretches guide dogs for years," said Ramona Nichols, director of Georgia Canines for Independer, who has collaborated in the investigation. "I'm impressed. Will revolutionize the field specializes in helping people with disabilities. "

In total, the robot was able to copy and commands 10 shares held by the dogs. These actions have included opening and closing a door with an efficiency impressive. It has also been able to open the door of a microwave or transporting an object and put it on a table.

"As robotic researchers we should not look only at men as a source of inspiration," says Kemp. "The dogs are highly trained to do what they do. They have helped thousands of people. I think we'll be able to get soon the dogs' skills. "

On the other hand, although it is clear that a robot can not imitate the personality and the company that gives a dog, has other advantages.

"The robot does not need the same care and maintenance the same," says Kemp. "And do not get distracted as can happen with dogs."

The creation of Molecular Biology Center promoted by the Nobel Severo Ochoa was a breakthrough

The good level of achievement Spain in biomedical research can not be explained without the figure of Severo Ochoa and the Nobel Prize he won in 1959, according to scientists all agree that English half-century later have made aid biomedical research senior European Research Council (ERC). In physics and engineering, by contrast, has not been a similar figure. Although there are English physicists who enjoy high international prestige - especially in the field of theoretical physics, rather than experimentally, the lack of a physical Ochoa explains the English science is not as competitive in these areas like biomedicine. "The creation of the Center for Molecular Biology powered by Ochoa was a breakthrough," says Luis Serrano, the Centre for Genomic Regulation.
