Research ArticleOpen accessIn the abstractEffects of Electromagnetic Field Frequency on the Behavior and Mortalities of Living OrganismsTatyana Degtyarevskaya, Andrei VokhmintsevThe objective of this investigation is to assess the influence of electromagnetic fields on living organisms. The impact of electromagnetic radiation of varying intensities on alterations in behavioral responses and mortality rates of living organisms was examined under controlled laboratory conditions at the first Moscow state medical university, named after I.M. Sechenov. The subjects of the study encompassed 10 specimens … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 19 Jan 2024 · 5,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractRadiation Triggered Phenotypic Changes of Regulatory T CellsLantao Liu, Yan Peng, Deqin Zhang, Dongsheng NiuIonizing radiation disrupts the immune balance easily. Regulatory T (Treg) cells directly affect the immune balance after radiation exposure. Meanwhile, the present study is to investigate the survival ability and phenotypic changes of Treg cells induced by 60Co γ-rays in order to expand the understanding on how Treg cells modulated by radiation. Mice lymphocytes were isolated from thymus and spleen … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 20 Mar 2022 · 5,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractReversible Ionizing Radiation Sensors Based on Carbon NanotubesKenneth Fontánez, Abniel Machín, María C. Cotto et al.Vertically Aligned Carbon Nanotubes (VA-CNTs) were grown by Chemical Vapor Deposition (CVD) on a silicon substrate with alternating layers of TiN and SiO2. VA-CNTs were exposed to X-ray radiation to study the change in resistivity later. Preliminary results show an increase in the resistivity of CNTs as a function of radiation exposure time, which means that the structure responds successfully … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 3 Feb 2020 · 7,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Ionizing Radiation Sensors Based on Carbon NanotubesKenneth Fontánez, Abraham García, María del C Cotto-Maldonado et al.SWNTs have been efficiently grown on patterned substrates, for its subsequent application to the development of ionizing radiation sensors. SWNTs before and after exposure to X-rays were characterized by Raman and XPS spectroscopy, revealing the appearance of alterations that have been justified as possibly due to the presence of adsorbed oxygen species. These materials have been used for the fabrication … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 29 May 2019 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtection of Human Albumin against UV-C Irradiation by Natural AntioxidantsAntonio Zuorro, Roberto LavecchiaThe use of UV-C light as a means to inactivate pathogens in biological media containing blood components or plasma derivatives has recently been rediscovered. Although highly effective, these treatments may have deleterious effects on plasma proteins such as albumin, fibrinogen and immunoglobulins. Here we investigate the use of three natural antioxidants, gallic acid, nicotinic acid and ascorbic acid, as potential … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 4 · 23 Oct 2018 · 9,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Plastic Wedges on Whole Foot Radiograph in Anteroposterior and Oblique PositionsPoe Lorlorm, Winit Choiprasert, Montree Tungjai, Suchart KothanThe whole foot radiography may be taken twice with different exposure parameters. It produces two images in two radiation exposures; one is the metatarsal view of the phalange and the other is a tarsal view. The aim of this study was to study the effects of plastic wedges on whole foot radiography with one radiation exposure. The plastic wedge was … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 27 Apr 2017 · 7,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuercetin Iron (III) Complex Enhances Radiation-Induced Cell Death in Human Erythroleukemic Cell Lines by Increasing the Generation of Intracellular ROSJiraporn Kantapan, Krai Daowtak, Kachaporn Gateprayoon et al.Quercetin iron (III) complex (IronQ) is a paramagnetic agent which exhibits several biological effects. Despite extensive studies about quercetin metal complex, the role of complexes to enhance the effect of radiation still remains unexplored. To this end, we determined whether and how IronQ sensitizes cancer cells to Ionizing Radiation (IR). Doxorubicin resistant leukemic cells (K562/Adr) and their parental cell lines … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 16 Jan 2017 · 8,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynchrotron Powder Diffraction Study of Radiation Damage in Langmuir Blodgett Nanotemplate Crystallised ProteinJonathan P. Wright, Eugenia Pechkova, Claudio NicoliniPolycrystalline samples of lysozyme were prepared with and without a Langmuir-Blodgett (LB) thin film template via both the hanging drop method and batch crystallisation. Powder diffraction methods are used to compare these samples and to measure their resistance to radiation damage at room temperature. The X-ray induced amorphisation of the samples was followed as a function of time and it … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 12 Nov 2014 · 8,175 accessesView PDFCite
Research ArticleOpen accessIn the abstractLANGMUIR-BLODGETT NANOTEMPLATE CRYSTALLIZATION COMBINED TO LASER-MICROFRAGMENTATION UNIQUELY CHARACTERIZE PROTEINS CRYSTALS BY SYNCHROTRON MICRODIFFRACTIONClaudio Nicolini, Luca Belmonte, Christian Riekel et al.Laser-induced microfragmentation of LB nanotemplate-induced protein crystals in glycerol solution results in distinct, coherently diffracting domains. Only crystals produced according to the Langmuir-Blodgett (LB) nanotemplate technique reveal in all four proteins being tested (lysozyme, insulin, thaumatin and ribonuclease) domains highly radiation resistant, while the crystals produced by the standard hanging drop crystallization method do not. Actually the very same laser … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 11 Feb 2014 · 7,984 accessesView PDFCite
