Biomedical applications of shape memory polymers (SMPs) are limited by their biostability, degradability, and possible toxicity risks after implantation. Mesoporous silica nanoparticles (MSNs) were used to increase the oxidative biostability (increase time until degradation occurs) using antioxidants and to induce oxidative degradation through incorporation of hydrogen peroxide-containing MSNs with modified surfaces. The presented results confirm increased oxidative stability using antioxidants, and alternatively, [...]

Regardless of their size, supported gold nanoparticles are largely used for liquid-phase oxidation reactions. Small gold nanoparticles exhibit good performance during the reduction of organic compounds. The direct reduction of carboxylic acid to aldehyde is a famous and familiar reaction in the field of organic chemistry and is considered as one of the fundamental chemical transformations. Herein, we present Au/hydrotalcite, Au/MgO, and Au/Al2O3 systems as heterogeneous versatile catalysts to realize the oxidation [...]

In the era of renewable and sustainable energy, perovskite materials remain pioneers as energy harvesting materials, be it thermoelectric waste heat harvesting or photovoltaic solar cell application. Oxide perovskite material is an emerging thermoelectric material in solving energy shortage issues through waste heat recovery. The chemical and structural stabilities, oxidation resistance, and cost-effective and straightforward manufacturing process are a few advantages of the oxide-based thermoelectric materials. Th [...]

Background: MicroRNAs (miRNAs) are small, non-coding RNAs that play a very important role in gene expression by regulating mRNA cleavage and translation. The Senegalese sole, Solea senegalensis (Kaup 1858), is a flatfish species that shows great potential for marine aquaculture. Nevertheless, the existence of sexual dysfunction of males reared in captivity, high larval mortality, and diseases have hampered its production. The integration of sequence information with data on chromosomal physical location is useful f [...]

To store CO2 in geological reservoirs, expansion valves have been used to intentionally release supercritical CO2 from high-pressure containers at a source point to lower-pressure pipelines and transport to a selected injection site. Using expansion valves, however, has some shortcomings: (i) the fluid potential, in the form of kinetic energy and pressure which can produce mechanical work or electricity, is wasted, and (ii) due to the Joule-Thomson cooling effect, the reduction in the temperature of the released CO [...]

Falls have negative consequences for older adults, but falls can be reduced through interventions that target the reduction of fall risk factors. Cognitive behavioral education programs and therapeutic yoga are two interventions that have independently been used as a means to reduce the risk of falls. The purpose of this study was to determine if adding therapeutic yoga following an education intervention improved well known fall risk factors. Potential participants were recruited through a senior center for a 12-w [...]

One of the most feared complications in liver transplantation is hepatic arterial thrombosis (HAT). The incidence of HAT in liver transplantation varies from 1.2% and 8%. One of the risk factors for this complication is anatomical complexity of hepatic arterial system. The focus of this short communication is to show our approach in dealing with aberrant left hepatic artery in settings of liver transplantation. This is a single center experience. Between January 2016 and June 2019, we procured and transplanted 357 [...]

Thalassemia syndromes are a group of hemoglobinopathies characterized by gene defects that disrupt normal hemoglobin production. Thalassemia intermedia (TI) is referred to as a group of disorders with a less severe form of the disease compared to thalassemia major. We present a case of a 60-year-old woman who was referred to a hematologist for chronic anemia and splenomegaly.

In this paper, we continue our previous work by discussing the consequences of curvature in spacetime caused by the presence of mass and the implications of this. We address the question raised by Dirac regarding the impact of a magnetic monopole on the quantum world. We discuss quantization concerning the solid angles observed, which may have a connection with a magnetic monopole.
