“…It has also been reported that aspartate and glutamate are among the amino acids most resistant to ionizing radiation, while cysteine is among the least resistant, 92 as well as aspartate and glutamate residues involved in the formation of salt bridges are less affected, and may even be completely resistant to radiation damage 37 . Remarkably, glutamate has been proposed as a dosimeter of γ‐radiation 93 …”

“…37 Remarkably, glutamate has been proposed as a dosimeter of γ-radiation. 93 The structural study of the PCNA Tg by X-ray crystallography, both global damage and specific damage, reveals that it is a protein with the intrinsic ability to resist high levels of ionizing radiation. Since all proteins have mainly the same repertoire of amino acids and interactions, it seems clear that their properties depend on a complex balance of these factors, 20,73,74 and it has also been suggested that the radioresistance shown by hyperthermophilic archaea could be a consequence of the adaptation of life at high temperatures.…”

Proliferating cell nuclear antigen (PCNA) is an essential protein for cell viability in archaea and eukarya, since it is involved in DNA replication and repair. In order to obtain insights regarding the characteristics that confer radioresistance, the structural study of the PCNA from Thermococcus gammatolerans (PCNA Tg ) in a gradient of ionizing radiation by X-ray crystallography was carried out, together with a bioinformatic analysis of homotrimeric PCNA structures, their sequences, and their molecular interactions. The results obtained from the datasets and the accumulated radiation dose

Objectives. Identify environmental particles in bronchus and human lung tissue through the SEM technique Methodology. The samples were fixed by immersion in 2% glutaraldehyde for 2 hours, then a wash with 1x pH 7 phosphate buffer and light agitation (x3) (1x, 2x and x3) was performed. Finally, the samples were critically dried out with a Samdri 795 team from Tousimis. This was the process to which the samples were taken for EDS analysis with a Jeol JSM 6610LV equipment, operating at 10kV, with Oxford Xmax EDS detector and Oxford AZtec software. The observation in the scanning electron microscope was performed with secondary electron detector. For the assembly, a sample holder was used for scanning electron microscopy, on a double-sided carbon tape substrate. The samples were given a coating with conductive material (99.9% gold) by sputtering with the Denton Vacuum V equipment. Contribution. In lung, 21 elements were identified, in addition to observing the shape and size of the particles. These images were compared with some other environmental particles presented by diverse authors. The uses of these elements were consulted and it was identified that some of them are used in the automotive, electrical and medical industries, and they also have a great influence on food.

Este artículo presenta la instrumentación electrónica de un sistema de biofiltración no convencional, que consta de tres biofiltros aerobios de flujo descendente para controlar el flujo de entrada/salida del agua residual y monitorear las variables de temperatura y color. Los biofiltros son usados en la remoción de colorantes tipo Azo, utilizados principalmente en el teñido de la mezclilla, las cuales debido a sus propiedades es difícil de degradar y son vertidos a las aguas de los ríos. Cada biofiltro se empacó con diferentes materiales, turba y perlita, inoculados con lodos aclimatados, para remover color y materia orgánica. Los resultados logrados consisten en mejorar el procedimiento de recolección y análisis de muestras realizadas en cada uno de los biofiltros, integrando sensores de color TCS230, sensores de temperatura PT100, electroválvulas que controlan el influente suministrado a cada uno de los biofiltros y la interfaz gráfica desarrollada en LabView, encargada de mostrar las mediciones de las variables físicas. La ventaja de un sistema de biofiltración automatizado es contar con mediciones en tiempo real y útil para otros estudios de diferente empacado del biofiltro. En este caso se observó que el biofiltro empacado con mezcla turba perlita presentó mayor remoción de color y materia orgánica.
