The disability, mortality and costs due to ionizing radiation (IR)-induced osteoporotic bone fractures are substantial no effective therapy exists. Ionizing increases cellular oxidative damage, causing an imbalance in turnover that is primarily driven via heightened activity of the bone-resorbing osteoclast. We demonstrate rats exposed sublethal levels IR develop fragile, bone. At reactive surface sites, cerium ions have ability easily undergo redox cycling: drastically adjusting their...
Exposure to ultraviolet radiation induces photodamage towards cellular macromolecules that can progress photoaging and photocarcinogenesis. The topical administration of compounds maintain the redox balance in cells presents an alternative approach combat skin oxidative damage. Cerium oxide nanoparticles (CNPs) act as antioxidants due their enzyme-like activity. In addition, a recent study from our group has demonstrated photoprotective potential tannic acid (TA). Therefore, this work aimed...
The COVID19 pandemic has brought global attention to the threat of emerging viruses and antiviral therapies, in general. In particular, high transmissibility infectivity respiratory have been general public's attention, along with need for highly effective disinfectant materials/products. This study developed two distinct silver-modified formulations redox-active nanoscale cerium oxide (AgCNP1 AgCNP2). show specific activities toward tested OC43 coronavirus RV14 rhinovirus pathogens,...
This study presents an antiviral self-cleaning fabric for masks/PPE applications with protection against human coronavirus.
In general, wound healing is a highly ordered process, with distinct phases of inflammation, proliferation, and remodeling. However, among diabetic patients, the progression through these often impeded by increased level oxidative stress persistent inflammation. Our previous studies demonstrated that cerium oxide nanoparticles (CNPs) conjugated therapeutic microRNA146a (miR146a) could effectively enhance targeting NFκB pathway, reducing present study, we consider potential effects...
The stability of microRNA-146a conjugated with different nanoparticles in the presence high oxidative stress was investigated through detailed electroanalysis.
Nanoscale cerium oxide has demonstrated substantial utility in biomedical applications. Among the various synthetic approaches, particles formed from addition of hydrogen peroxide have shown a unique functional and physicochemical character, suggesting an implication synthesis method particle performance (e.g., free radical scavenging activity modulation oxygen metabolism). In this study, we observe influence aging aqueous environment for up to 8 weeks identify three distinct material life...
The COVID-19 pandemic marks an inflection point in the perception and treatment of human health. Substantial resources have been reallocated to address direct medical effects curtail spread virus. Thereby, shortcomings traditional disinfectants, especially their requirement for regular reapplication related complications (e.g., dedicated personnel short-term activity), become issues at forefront public health concerns. This issue became pressing when infection-mitigating supplies dwindled...
Abstract The aim of this study was to develop a novel biodegradable magnesium (Mg) alloy for bone implant applications. We used scandium (Sc; 2 wt %) and strontium (Sr; as alloying elements due their high biocompatibility, antibacterial efficacy, osteogenesis, protective effects against corrosion. In the present work, we also examined effect heat treatment process on properties Mg‐Sc‐Sr alloy. Alloys were manufactured using metal casting followed by treatment. microstructure, corrosion,...
