A UGR method allows to determine if a person infected with AIDS contracted the disease in the last six months

10.11.2006
AIDS is still one of the top priority points of the international scientific agenda. In this sense, the group Virus transmission by blood of the University of Granada (Universidad de Granada fits into the AIDS Research Network, in a project coordinated from Barcelona and made up of 32 national centres. It is focused on the development of an algorithm to predict if the virus carrier became infected before or after six months.

At present, there is not any similar methodology and, therefore, this network will allow to carry out a systematization of the new infections and, this way, assessing the epidemiological pattern and the transmission ways of the persons who become infected nowadays in our country. In this sense, the University of Granada applies techniques to check “the antibodies’s avidity for interacting with the antigens of the HIV(human immunodeficiency virus which causes the AIDS disease)”, points out doctor Carmen Bernal Zamora, promoter of these research works in the UGR [http://www.ugr.es].

The antibodies generated in the first months after the infection present an affinity with the virus different to the later ones. Normally, a very low avidity rate is a sign that the antibodies have raised as a consequence of a recent infection. The results obtained with these trials have been presented in the International Conference of Internal Medicine recently held in the University of Granada.

A reliable diagnostic in less time

Other works carried out by doctor Bernal are related to the decrease of the wait time to obtain a reliable diagnostic. Nowadays, a person who wants to know if he is infected with the VIH, is advised to wait 2 months after the last risk contact: a sexual relationship without protection, the use of a syringe which has been used before by another person...

However, new techniques are being implemented at present to reduce the necessary time to do a diagnostic between four and six weeks after the infection. According to Bernal, it has been possible thanks to the use of techniques which allow to detect at the same time the antibodies and the antigens created by the organism after the contact with the HIV.

Studies with anti-retroviral drugs

In the same way, doctor Federico García García is working, in the same network, on the resistance to the HIV treatment. The studies are aimed at checking if the virus´ sequence has suffered a mutation and if it conditions its resistance to certain drugs. This way, we can get to know if an increase of the viral charge is due to a therapeutic fail to change the treatment.

Such studies on anti-retrovirals are very important in a moment in which the international scientific community has admitted that society has generated false expectances on a vaccine will take a long time to appear as, among other questions, it is a virus characterized by a great ability to mutate.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
