Uso de los otogramas en el sistema probatorio penal
The othograms, impressions, imprints or traces of ear, have been admitted as evidence
in the Spanish criminal proceedings at the beginning of the 21st century. Previous
studies sized ears using subjective elements with the disadvantage that two
researchers could be classified differently the same ear or its mark. The problem with
the tracks has been fixed by introducing a classification method as it exists also in
dactiloscopy. This method of identification is today in development and an
improvement in the development of its results can be observed. In this article we have
studied 150 othogramas (75 of each ear) with the system of classification of the Diego-
Da Silva-Curiel. Used othogramas were obtained from the file of the Brigade
Provincial Valladolid scientific police and the Commissioner of the national body of
police Miguel Angel de Diego. We have studied the sentences of the Spanish courts
where the othograma as evidence has been used in the process.Los otogramas, impresiones, improntas o huellas de oreja, han sido admitidos como

TLR4-Binding DNA Aptamers Show a Protective Effect against Acute Stroke in Animal Models.
Since Toll-like receptor 4 (TLR4) mediates brain damage after stroke, development of TLR4 antagonists is a promising therapeutic strategy for this disease. Our aim was to generate TLR4-blocking DNA aptamers to be used for stroke treatment. From a random oligonucleotide pool, we identified two aptamers (ApTLR#1R, ApTLR#4F) with high affinity for human TLR4 by systematic evolution of ligands by exponential enrichment (SELEX). Optimized truncated forms (ApTLR#1RT, ApTLR#4FT) were obtained. Our data demonstrate specific binding of both aptamers to human TLR4 as well as a TLR4 antagonistic effect. ApTLR#4F and ApTLR#4FT showed a long-lasting protective effect against brain injury induced by middle cerebral artery occlusion (MCAO), an effect that was absent in TLR4-deficient mice. Similar effects were obtained in other MCAO models, including in rat. Additionally, efficacy of ApTLR#4FT in a model of brain ischemia-reperfusion in rat supports the use of this aptamer in patients undergoing artery recanalization induced by pharmacological or mechanical interventions. The absence of major toxicology aspects and the good safety profile of the aptamers further encourage their future clinical positioning for stroke therapy and possibly other diseases in which TLR4 plays a deleterious role
