ionizingradiation, etc ; artificial skin; biomarkers; evolution; exposure duration; exposure models; skinning; wills; Show all 8 Subjects
Abstract:
... There is a growing need to uncover biomarkers of ionizing radiation exposure that leads to a better understanding of how exposures take place, including dose type, rate, and time since exposure. As one of the first organs to be exposed to external sources of ionizing radiation, skin is uniquely positioned in terms of model systems for radiation exposure study. The simultaneous evolution of both MS ...

Abstract:
... This paper proposes an innovative utilization method of boron bearing blast furnace slag (B³FS) as a highly cost-effective shield for protection against neutron radiation hazards, thereby conserving natural resources and preventing environmental pollution. Characteristic of the shielding performance of the prepared composites against thermal neutrons were tested by an Am–Be neutron source combined ...

Abstract:
... Using mitochondria-targeted TALENS and ionizing radiation, consequences of mtDNA double-strand (ds) breaks were investigated by Tigano et al. (2021) who uncovered mtRNA as a retrograde second messenger of this form of mtDNA stress that activates the RIG-I/MAVS innate immune signaling pathway. ...

Abstract:
... As a versatile quantification and tracking technology, ¹⁹F magnetic resonance imaging (¹⁹F MRI) provides quantitative “hot-spot” images without ionizing radiation, tissue depth limit, and background interference. However, the lack of suitable imaging agents severely hampers its clinical application. First, because the ¹⁹F signals are solely originated from imaging agents, the relatively low sensit ...

Abstract:
... (1) Background: Developments in accelerator-based neutron sources moved boron neutron capture therapy (BNCT) to the next phase, where new neutron radiation parameters had to be studied for the treatment of cancers, including brain tumors. We aimed to further improve accelerator-BNCT efficacy by optimizing dosimetry control, beam parameters, and combinations of boronophenylalanine (BPA) and sodium ...

Abstract:
... Magnetic particle imaging (MPI) has recently emerged as a promising non-invasive imaging technique because of its signal linearly propotional to the tracer mass, ability to generate positive contrast, low tissue background, unlimited tissue penetration depth, and lack of ionizing radiation. The sensitivity and resolution of MPI are highly dependent on the properties of magnetic nanoparticles (MNPs ...
... Disinfestation of insect pests is a crucial unit operation to save the quality of food grains during the storage. Several methods of disinfestation are available including chemical and non-chemical methods. However, the use of the chemical method is avoided because of its adverse effects on the environment and studies show that chemical methods have failed frequently in recent years. This paper re ...

Abstract:
... Preparation for oxidative stress (POS), i.e., the upregulation of endogenous antioxidants, is a widespread response of animals exposed to extreme conditions. This response has been described for more than 80 animal species belonging to eight phyla during hypometabolism or situations that limit oxygen availability. The pattern of the typical POS-response, in which a mild redox imbalance triggers an ...
ionizingradiation, etc ; air; diagnostic techniques; emissions factor; remote sensing; spectroscopy; uranium; Show all 7 Subjects
Abstract:
... Optical measurement techniques can address certain important challenges associated with nuclear safety and security. Detection of uranium over long distances presents one such challenge that is difficult to realize with traditional ionizing radiation detection, but may benefit from the use of techniques based on intense femtosecond laser pulses. When a high-power laser pulse propagates in air, it ...

Abstract:
... Radiation Shielding Concrete (RSC) is a superior alternative to many conventional and modern shields against gamma and neutron radiation hazards. The present work is the first comprehensive review on utilization of alternate materials, emphasizing hazardous industrial byproducts, as constituents of RSC. Such usage enhances the performance, sustainability, and affordability of RSC. Added advantages ...

Abstract:
... Chemometric analysis of near infrared (NIR) spectroscopy data was applied to investigate the possibility to rapidly detect dry fermented sausages treated with ionizing radiation at 0; 0,5; 1; 2 and 3 kGy. NIR spectra from 1000 to 2500 nm were subjected to an exploratory principal component analysis (PCA) followed by orthogonal partial last square-discriminant analysis (OPLS-DA) to develop classifi ...
... This paper evaluates the significant historical paper of Muller and Mott-Smith (1930), which successfully disputed the proposal of Olson and Lewis (1928) that background ionizing radiation is the driving mechanism of evolution. While the present analysis supports the general conclusion that background radiation is not a quantifiable factor affecting evolution, the paper reveals methodological erro ...

Abstract:
... Antibiotics are becoming emerging contaminants due to their extensive production and consumption, which have caused hazards to the ecological environment and human health. Various techniques have been studied to remove antibiotics from water and wastewater, including biological, physical and chemical methods. Among them, advanced oxidation processes (AOPs) have received increasing attention due to ...

Abstract:
... To date, impacts of ionising radiations have been largely disregarded in Life Cycle Assessment (LCA). This omission can be linked to the lack of a standard and comprehensive framework for including the effects of radionuclides alongside other emissions from industrial processes. Drawing on a recent review of Radiological Impact Assessment methodologies for LCA studies, this article proposes an ove ...

Abstract:
... Chromosomal breaks occur in the genome of all living organisms upon exposure to ionizing radiation, xenobiotics and as intermediates during normal cell cycle progression. Most of the information on DNA repair process has emerged from bacteria, human, mice, and yeast while information on plant DNA repair genes and proteins is limited. Among other DNA repair proteins, MRE11 forms the core of the MRN ...

Abstract:
... Ionizing radiation (IR) induced mitochondrial dysfunction is associated with enhanced radiation stimulated metabolic oxidative stress that interacts randomly with intracellular bio-macromolecules causing lethal cellular injury and cell death. Since mild mitochondrial uncoupling emerged as a valuable therapeutic approach by regulating oxidative stress in most prevalent human diseases including agei ...
... PrC-210 is a direct-acting ROS-scavenger. It's active when administered orally, IV, or topically; it has none of the nausea/emesis nor hypotension side effects that have precluded human amifostine use. PrC-210 confers 100% survival to mice and rats that received an otherwise 100% lethal radiation dose and 36% reduction of ischemia-reperfusion-induced mouse myocardial infarct damage, and thus is a ...

Abstract:
... Fuel cell electric vehicles promise to be a viable technical option for using surplus energy produced by renewables, and in turn, help the transport sector to reduce environmental impacts. However, the technology is still under development and, for some components, the environmental performance is uncertain, e.g. the hydrogen storage tank. Manufacturers produce hydrogen tanks consisting of carbon ...
