Pycnogenol (R) protects against ionizing radiation as shown in the intestinal mucosa of rats exposed to X-rays
(John Wiley & Sons LtdChichesterInglaterra, 2006)
Limitación de dosis de rayos X en odontología. Revisión narrativa
(Universidad de Talca (Chile). Escuela de Odontología., 2022)
Comparative test of radiological exposure between femoral and radial techniques, development of a protective device and clinical trial design
Background Interventional procedures via radial technique have progressively increased due to improved patient comfort, lower complication rates and reduced mortality in some scenarios. One area of interest is radiation ...
Occupational radiation exposure in vascular interventional radiology: A complete evaluation of different body regions
Purpose To perform a complete evaluation on radiation doses, received by primary and assistant medical staff, while performing different vascular interventional radiology procedures. Materials and methods We evaluated dose ...
Radiation Damage Mechanisms of Monolayer-Protected Nanoparticles via TEM Analysis
(American Chemical Society, 2017-11-19)
In this work, it is shown that thiol-protected Au nanoparticles (AuNPs@SR) of approximately 3.4 nm size suffered unexpectedly high radiation damage under standard transmission electron microscopy (TEM) operating conditions. ...
Dynamics of potentially protective compounds in Rhodophyta species from Patagonia (Argentina) exposed to solar radiation
(Elsevier Science Sa, 2004-07)
The impact of solar radiation upon potentially protective compounds (i.e., UV-absorbing compounds and carotenoids) was assessed in four Rhodophyte species from Patagonia (i.e., Ceramium sp. Lyngbye, Corallina officinalis ...
Proteção à radiação ultravioleta: recursos disponíveis na atualidade em fotoproteção
(Sociedade Brasileira de Dermatologia, 2011)
A radiação ultravioleta pode provocar danos ao DNA, imunossupressão, alterações químicas e histológicas na epiderme, envelhecimento precoce, cataratas e carcinogênese, dentre outras deteriorações. A fotoproteção previne ...
Evaluation of exposure of a multidisciplinary team to ionizing radiation due to the use of fluoroscopy equipment in a surgical centerAvaliação da exposição à radiação ionizante em equipe multidisciplinar devido ao uso de equipamentos de fluoroscopia no centro cirúrgico
Introduction: Ionizing radiation-producing equipment is used in surgical centers to guide invasive procedures. Technological advances have enabled improvements in image quality, which may be accompanied by increased radiation ...
Possible radio-protective effect of folic acid supplementation on low dose ionizing radiation-induced genomic instability in vitro
(National Institute of Science Communication, 2016-08)
Ionizing radiation induces DNA damage through the production of single-strand breaks, double-strand breaks and reactive oxygen species. Folic acid (FA) can prevent DNA damage. We hypothesized that in vitro supplementation ...
