No statistical relationship existed between the likelihood of developing PE and patient age, hemoglobin, hemoglobin S%, length of stay in ICU, and mortality.

The demographic characteristics of the population included a male predominance, age in the mid-thirties, and vaso-occlusive crisis diagnosis upon admission to the ICU. The incidence of PE was significantly related to female gender. No significant relationship existed between the likelihood of developing PE and age, hemoglobin, hemoglobin S%, length of ICU stay, or mortality.

To map research production by Saudi-affiliated investigators in order to identify areas of strength and weakness.Method We followed the Arksey and O'Malley (2005) framework. Medline and Cochrane databases were searched with a focus on identifying articles related to COVID-19 and Saudi Arabia following the PRISMA protocol. The study was conducted at KingSaud University, Riyadh, Saudi Arabia between March and May 2020.Results A total of 53 articles were ultimately included. Most of the research production from Saudi Arabia was opinion and narrative reviews related to the clinicopathological features of COVID-19 as well as control and prevention of virus spread.Conclusion The results of this scoping review identify a relative deficiency in original research, which requires further investigation.

We have systematically searched for superconductivity among MXenes for a range of transition metal elements, based on a full first-principles characterization in combination with the Eliashberg formalism. Thus, we identified six superconducting MXenes three carbides (Mo2C, W2C and Sc2C) and three nitrides (Mo2N, W2N and Ta2N). The highest critical temperature of ∼16 K is found in Mo2N, for which a successful synthesis method has been established [Urbankowski et al., Nanoscale, 2017, 9, 17722-17730]. Moreover, W2N presents a novel case of competing superconducting and charge density wave phases.The vital functions of cell membranes require their ability to quickly change shape to perform complex tasks such as motion, division, endocytosis, and apoptosis. Membrane curvature in cells is modulated by very complex processes such as changes in lipid composition, the oligomerization of curvature-scaffolding proteins, and the reversible insertion of protein regions that act like wedges in the membrane. But, could much simpler mechanisms support membrane shape transformation? In this work, we demonstrate how the change of amphiphile topology in the bilayer can drive shape transformations of cell membrane models. To tackle this, we have designed and synthesized new types of amphiphiles-Janus dendrimers-that self-assemble into uni-, multilamellar, or smectic-ordered vesicles, named dendrimersomes. We synthesized Janus dendrimers containing a photo-labile bond that upon UV-Vis irradiation cleavage lose a part of the hydrophilic dendron. This leads to a change from a cylindrically to a wedge-shaped amphiphile. The high mobility of these dendrimers allows for the concentration of the wedge-shaped amphiphiles and the generation of transmembrane asymmetries. The concentration of the wedges and their rate of segregation allowed control of the budding and generation of structures such as tubules and high genus vesicles.Dielectric capacitors with the prominent features of ultrafast charging-discharging rates and ultrahigh power densities are ubiquitous components in modern electronics. To meet the growing demand for electronics miniaturization, dielectric capacitors with high energy storage properties are extensively researched. Here we present an overview of the recent progress in the engineering of multiscale structures of dielectric ceramics ranging from bulk to thin films. This article commences with a brief introduction of the fundamentals of dielectric ceramics, including primary parameters, a library of dielectric ceramics, and multiscale structures. Emphases are placed on the relationship between multiscale structures and energy storage properties and the rational structure design principles in dielectric ceramics. Also included are currently available multilayer ceramic capacitors based on multiscale engineered ceramic structures. Finally, challenges along with opportunities for further research and development of high-performance dielectric ceramics for electrostatic energy storage are highlighted.
