With the flourishing development of (CH3NH3)PbI3, three-dimensional (3D) organic-inorganic perovskites with unique structure-property flexibility have become a worldwide focus. However, they still face great challenges in effec-tively inducing ferroelectricity. Despite the typical 3D perovskite structure and the ability of dabco to trigger phase transition, unfortunately [H2dabco]RbCl3 (dabco = 1,4-diazabicyclo[2.2.2]octane) adopts a nonpolar crystal structure without ferroelectricity. Within larger RbI3 framework, we assemble N-methyl-dabco gained by reducing the molecular symmetry of dabco into a new 3D organic-inorganic perovskite...

OBJECTIVES: Crocin is derived from dried stigmas of Crocus sativus L. (saffron). It has long been used to prevent and treat various diseases. Although crocin is suggested as one of the most effective cancer therapeutic constituents of saffron stigma, its exact molecular mechanisms are not fully understood. In this study, we reviewed anticancer effects of crocin and its underlying molecular mechanisms. KEY FINDINGS: While several mechanisms may account for the antitumour activity of crocin, alteration of expression/activity of the genes and also epigenetic changes may be considered as necessary phenomena...

Inhibition of lactate dehydrogenase (LDH) represents an innovative approach to tackle cancer because this peculiar glycolytic metabolism is characteristic of most invasive tumor cells. An investigation into the biological properties of saffron extracts led to the discover of their LDH-inhibition properties. In particular, the most important saffron components, crocetin, was found to inhibit LDH (IC50 = 54.9 ± 4.7 μM). This carotenoid was independently produced by chemical synthesis, and its LDH-inhibition properties manifested via its antiproliferative activity against two glycolytic cancer cell lines (A549 and HeLa, IC50 = 114...

Phospholipids are shown by solvent penetration experiments to form lamellar phases and spontaneously spawn vesicles in a wide range of deep eutectic solvents (DESs) composed of alkylammonium halide salts and glycerol or ethylene glycol, which are shown to be nanostructured by X-ray scattering. In contrast with molecular solvents, the chain melting temperature of each phospholipid, which determines the stability of the swellable bilayer phase, depends on the structure of the cation, anion, and molecular H-bond donor that constitute the DES...

Calgranulin proteins are important mediators of innate immunity and are members of the S100 class of the EF-hand family of calcium binding proteins. Some S100 proteins have the capacity to bind transition metals with high affinity and effectively sequester them away from invading microbial pathogens in a process that is termed "nutritional immunity". S100A12 (EN-RAGE) binds both zinc and copper and is highly abundant in innate immune cells such as macrophages and neutrophils. We report a refined method for the expression, enrichment and purification of S100A12 in its active, metal-binding configuration...

The effect of cold plasma on crocin esters and volatile oils of saffron was studied for the first time. After the treatments, (Ar, Ar/5% O2 and Ar/10% O2 at 8 and 12kV of voltage), a decrease in crocin esters and saffranal and an increase in isophorone and 4-ketoisophorone was observed. After 4min, the saffron samples treated with Ar/20% O2 had blackened and the treatment was discontinued. The results show that increasing the input voltage and increasing the amount of added oxygen to Argon gas increased the changes in the safranal and crocin esters...

Neurotoxicity and the accumulation of extracellular amyloid-beta1-42 (Aβ) peptides are associated with the development of Alzheimer's disease (AD) and correlate with neuronal activity and network dysfunctions, ultimately leading to cellular death. However, research on neurodegenerative diseases is hampered by the paucity of reliable readouts and experimental models to study such functional decline from an early onset and to test rescue strategies within networks at cellular resolution. To overcome this important obstacle, we demonstrate a simple yet powerful in vitro AD model based on a rat hippocampal cell culture system that exploits large-scale neuronal recordings from 4096-electrodes on CMOS-chips for electrophysiological quantifications...
