A team of biophysicists at the UAB have discovered the molecular process involved in AIDS and present their results. In their laboratory they artificially recreated part of the viral process and their conclusions are interesting. Peptides, which enable the virus to fuse with our cells, have a...
The oral antibiotics are administered systematically before a colon surgery. But, is it really necessary this medication? Investigators of the Hospital Vall d'Hebron and UAB think that it is not. This categorical negative reflects the results of a study in which participated 300 people in this situation.
Plants can be victims of aluminium's toxicity, wich, for example, affects the growth of the roots. In response of this, plants like corn have generated defence mechanisms. They produce compounds that had already been studied for their resistance to pesticides or their defence...
Chromosomes are composed of a material named chromatin. Generally it is accepted that DNA is packaged in chromosomes during mitosis following a succession of chromatin fiber folds. According to a study carried out by UAB researchers, in addition to...
The Catalonian donkey is one of the most endangered donkey breeds in the world. In this study, the investigators J.P. Gutierrez, J. Marmi, F. Goyache i J. Jordana analysed the pedigree information of the Catalonian donkey herdbook to assess the genetic diversity and population structure of the breed. They found that the Catalonian donkey has...
Alcoholism and the hepatic alcoholic illness are heterogeneous clinical entity. We still don't known why people become alcoholic. We also don't known why only a part of them develop the hepatic alcoholic illness. Since the environmental factors do not explain everything, the research efforts are studying the genetic determinants of people. This...
In according with our temperament we run the risk of being an addict. Investigators of the Institute of Neurosciences suggest that people who search constantly new sensations are potentially addicts. This conclusion is the fruit of a study produced with morphine and snooper rats.
Sometimes and without a clock we are capable to tell what time it is or to wake up an hour in particular. Scientists suspect that this skill is mechanized in some place of our body. Investigators of the Service of Neurology have stimulated and inhibited parts of the brain supposedly implied. The results discard the role of the prefrontal lobe...
A team of researchers of the UAB have developed a process which could increase the computer storage capacity. This application is due to the study of the magnetical properties of circular structures with submicrometrics size. By means of these tiny disks, the researchers have obtained "Exchange Biased Vortices", that could rise the magnetic...
Gold nanoparticles have unusual properties compared with other elements. We have taken advantage of this characteristic to create a new type of biological marker. The Sensors and Biosensors Group at the UAB, jointly with the Institute of Molecular...
