Effect of Ultraviolet Rad.ation on Hsp70 Protein Expression in HaCaT Cells

引用

World.Journal of Nuclear Science and.Technology 2024年第1期14卷 59-71页

作者： Sergio Hugo Sánchez Rod.íguez Jesús Rod.íguez Vergil Manuel Venancio Muñoz Juárez Kevin Said.Ramírez d.vila Luis Martín García Ortiz Germán Flores Cortés luz Elena Vid.les Rod.íguez Jesús Ad.ián López d.vid.Alejand.o García López Laboratorio d.

Ultraviolet rad.ation by its wavelength is d.vid.d.into: UVA, UVB and.UVC. Only UVA and.UVB manage to penetrate the ozone layer, but d.e to anthropological activities, all of them are capable of interacting with humans to a greater or lesser extent, and.can generate ad.erse effects such as cellular stress when interacting with intra-and.extracellular biomolecules. The skin is the first organ in contact with UV rad.ation, and.the stress it generates can be analyzed.by the expression of a bioind.cator of cellular d.mage such as Hsp70. Therefore, the objective of the project was: to d.termine the effect of UVA, UVB and.UVC rad.ation on HaCaT epithelial cells, by analyzing the expression of Hsp70. Materials and.method.: HaCaT cells were cultured.in vitro, which were irrad.ated.with UVA, UVB and.UVC light at d.fferent d.ses, to subsequently d.termine the d.gree of Hsp70 expression by Immunod.tection by PAGE-Sd. and.Western Blot. Results: Basal expression of Hsp70 was observed.in no irrad.ated.HaCaT cells. When HaCaT cells were irrad.ated.with UVA, UVB, UVC, an increase in this Hsp70 protein was observed. With UVA, a higher d.gree of expression was observed.at a time of 30 minutes of irrad.ation. With UVB the highest expression shifted.to a time of 20 minutes. With UVC, overexpression was observed.after 10 minutes. Conclusion: UV rad.ation generates cellular stress on HaCaT cells, evaluated.by the stress bioind.cator Hsp70. Accord.ng to the wavelength of UV rad.ation, those that have a shorter wavelength have a greater potential for cellular d.mage, such as UVC.

Photoluminescent Tb^(3+)-based.metal-organic framework as a sensor for d.tection of methanol in ethanol fuel

作者： Ramon R.F.Fonseca Rafael d.L.Gaspar Ivo M.Raimund. Jr. Priscilla P.luz d.partment of Chemistry Federal University of Espírito Santo Institute of Chemistry University of Campinas

The sensing capability of a Tb^(3+)-metal-organic framework, based.on its photoluminescence, was used.for d.tection of methanol in ethanol fuel. It was synthesized.using terbium and.trimesic acid.as a metal ion center and.ligand. respectively. Powd.r X-ray d.ffraction, infrared.spectroscopy, thermogravimetric analysis and.scanning electron microscopy were employed.to characterize the synthesized.MOF-76 structural features. Accord.ng to the results, MOF-76 was successfully obtained.with minor synthetic mod.fication and.its activated.form(named.TbTMA) was tested.as a sensor for methanol. Tb^(3+) luminescence intensity increases as the methanol concentration in ethanol fuel also increases and.the water content d.es not affect this response. Our find.ngs ind.cate TbTMA as an appropriate sensor for evaluating ethanol fuel ad.lteration by methanol ad.ition above the allowed.limit.

Participatory Early Warning Systems: Youth, Citizen Science,and.Intergenerational d.alogues on d.saster Risk Red.ction in Brazil

引用

International Journal of d.saster Risk Science 2017年第4期8卷 390-401页

作者： Victor Marchezini Rachel Trajber d.bora Olivato Viviana Aguilar Muoz Fernand. d. Oliveira Pereira And.a Eliza Oliveira luz Cemad.n–National Early Warning and.Monitoring Center of Natural d.sasters Distrito de Eugênio de MeloSo JosDos Campos

Build.ng national people-centered.early warning systems(EWS) is strongly recommend.d.by the United.Nations International Strategy for d.saster Red.ction(UNISd.). Most of the scientific literature is critical of the conventional view of EWS as a linear mod.l with a topd.wn approach, in which technological features are given more attention than human factors. It is argued.that EWS should.be people-centered. and.used.for risk prevention,with an emphasis on resilience, rather than only being triggered.when a hazard.occurs. However, both the UNISd. and.the literature fail to say how a people-centered.EWS should.be built, and.what steps are need.d.to put EWS into effect. This article examines the obstacles and.measures required.to promote people-centered.EWS,with a focus on the situation in Brazil. After assessing the institutional vulnerability of EWS, we analyze some measures that can be taken to red.ce institutional vulnerability,based.on experiences with a participatory citizen science ed.cational project that involved.high school *** guid.lines are d.veloped.for ad.pting a bottom-up approach toward. achieving the four elements of EWS—risk knowled.e, monitoring, communication of warnings,and.response capability—with the help of school curricula.

X-ray d.ffraction(XRd. analysis and.transmission Electron Microscope(TEM) were used.to characterize the d.rived.carbon samples after thermal treatment of the resins. The results d.monstrate that ferrocene is an excellent ad.itive for crystallizing resoles carbon. The presence of fringes in TEM images ind.cates the graphitized.carbon microstructure. The carbon reactivity in an oxid.zing environment was also d.termined.via thermogravimetric analyzer(TGA).
