Cell damage caused by the pesticide DDT is palliated

University of Cordoba researchers manage to reduce oxidative stress brought about by this well-known pesticide in mice via a selenium-enriched diet
Since it was first synthesized almost 150 years ago, the pesticide Dichlorodiphenyltrichloroethane, better known as DDT, has been widely used to fight illnesses caused by insects. Later, it was proven to not only kill off the species it targeted, but also wreaked havoc on the environment, on human beings and on other species in the ecosystem.

A University of Cordoba research team has developed a tool to erase molecular tags that silence genes involved in tumor growth

Plants have provided a new avenue in curbing tumor growth. On this occasion, it doesn’t involve miracle species or the like, but rather the results obtained by the University of Cordoba BIO301 research team called "Epigenetics and DNA Repair." This research team is affiliated with the Maimonides Institute of Biomedical Research and is led by Genetics Professor María Teresa Roldán Arjona.

Without overlooking the risks of using social networks in adolescence, a study analyzes  little known information about cybergossiping among high school students 

Cybergossiping occurs when two or more people make evaluative comments on a digitial device about a third person who is not present.  This kind of online behavior is common among adolescents when they are instant messaging and on social networking sites. Cybergossiping directly impacts the group, and can just as easily foster as damage the quality of the relationships among its members.

The social media are undermining young people’s self-esteem

A study by the University of Córdoba shows how use of the social media by young people adversely affects their self-perception of body image, and links this phenomenon to eating disorders

The social media are part of our everyday lives, enabling new methods of communication, improved access to information and even the development of new working strategies, in a range of fields including education. Yet the use – or abuse – of social media has also given rise to a number of problems, particularly among the most exposed sectors of the population.

An experiment in mice palliates kidney disease caused by diabetes

An experiment in mice palliates kidney disease caused by diabetes

Research group succeeds in removing a protein from kidney cells involved in blood filtration
Diabetes has become a major health problem worldwide; some estimates suggest that in twenty years' time there will be around 600 million diabetics. The disease is caused by impaired insulin secretion, which in turn hinders cell glucose uptake; as a result, sugar levels in the bloodstream remain excessively high. One of the most common complications of diabetes is diabetic nephropathy, a disease which affects the ability of the kidneys to eliminate waste matter.

Researchers disprove one of the most widespread assumptions among geneticists regarding DNA

A study by a Córdoba research team,  just published in Proceedings of the USA National Academy of Sciences, shows that spontaneous DNA gaps are not – as hitherto believed – equivalent to those produced during DNA repair
Ever since DNA was first isolated in 1869, the scientific community has constantly sought to determine how it works, and reveal its secrets. Despite advances in this field, a great deal still remains to be discovered. A good example is the research published today in Proceedings of the USA National Academy of Sciences (PNAS) by a University of Córdoba research groupassigned to the Instituto Maimónides de Investigación Biomédica (IMIBIC) andled by two professors in the Department of Genetics, Rafael Rodríguez Ariza and María Teresa Roldán Arjona.
