COVID-19 infections, hospitalizations, and deaths continue to skyrocket across the world, leaving a trail of enduring psychological turmoil. It wreaks havoc on the physical, emotional, and cognitive health of those directly infected, as well as caretakers, friends, and families. Though the pandemic has at least indirectly impacted most people, older adults appear to be the most vulnerable to COVID-19-related deaths and little is known about the psychological consequences. Unfortunately, many of the precautions take [...]

Ilmenite is a mineral whose crystallinity can be altered by chemical treatment, producing TiO2 and iron and titanium-based metal nanocomposites, which are applicable mainly for photocatalysis. Porous and crystalline biomass-derived carbon materials include graphene oxide, reduced graphene oxide, graphitic carbon nitride, catalytically graphitized sucrose and chitosan, and activated carbon. Ilmenite-based metal oxides coupled with biomass-based carbon materials are effective in environmental remediation, especially [...]

The COVID-19 outbreak has been associated with various psychological problems, such as Cyberchondria, constant research for information online, to obtain health-related information. This was associated with problematic social media use and various psychological problems. This study aimed to measure the characteristics of fear and anxiety of COVID-19, the generalized approach to online searching and the use of the Internet about the perception of health, during a pandemic. The online survey was disseminated from Apr [...]

This review summarizes the latest results from the interventional clinical trials for inducing clinical tolerance in the recipients of human leukocyte antigen (HLA)-matched or mismatched living donor kidney transplants via allogeneic hematopoietic stem cell (HSC)-based therapies. The protocols utilized by the three medical centers in the United States differ in degree of HLA-matching, relatedness or unrelatedness, donor cell composition of the hematopoietic stem cells transplant (HSCT), timing for infusion and cond [...]

In the 1950’s Denham Harman proposed the Free Radical Theory of Aging whereby species lifespan and individual longevities are the consequence of free radical driven damage to biomolecules. This led to decades of research to ascertain the effect of altered antioxidant defense systems on aging and mortality in an array of species using reverse genetics and dietary manipulation. Within invertebrates, the data generally support the Free Radical Theory in that overexpression of antioxidant enzymes or dietary supplementa [...]

A unique two-Pathways process using aqueous sodium glycinate for CO2 capture from a split flue gas stream emitted from 600 MWe post-combustion coal power plant was developed in Aspen Plus v.10. The split gas flow rate used was 44.75 ton/h and contained 0.0023 mol% SO2 and 13.33 mol% CO2. The process includes a washing unit, a CO2 absorption unit, a reverse osmosis unit, and a solvent regeneration unit or an ultrafiltration unit. The washing unit uses deionized water to completely remove SO2 and the CO2 absorption u [...]

Burnout is a chronic state of exhaustion caused by prolonged stress. Medical training has been shown to leave many medical students vulnerable to burnout, which can negatively impact their health and patient care. While resilience has been associated with lower burnout, the mechanisms through which resilience reduces burnout are not well established. Therefore, this study aimed to investigate whether difficulties with emotion regulation mediate the relationship between resilience and burnout among medical students. [...]

In this study, we investigated the oligomerization mechanism of the Fischer-Tropsch synthesis catalyzed by a cobalt-based catalyst supported by SBA-15. The Co/SBA-15 catalyst contained 20% w/w of cobalt. It was prepared by the wet impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption-desorption, temperature-programmed reduction (TPR), and scanning electron microscopy coupled to X-ray energy dispersion spectroscopy (SEM-EDS). The FT synthesis was conducted in a slurry bed reactor operating [...]

Road traffic is a significant source of air pollution that has a harmful impact on human health. To reduce the health and environmental impacts of fossil fuel consumption in the transportation sector, many countries have implemented policies to promote the deployment of electric vehicles (EVs). A vital factor to consider when designing policies to support EV use is the monetized health impacts of fossil fuel consumption. This research aims to investigate the health benefit of replacing internal combustion engine ve [...]
