It seems probable that, even if diverse in their nature, the traces of fire exposure are linked to the atmosphere of religious changes that was omnipresent during this period.The aim of this work was to document and analyze an exceptionally preserved mummified body of a six-year-old boy found in a family tomb in Skalná, Czech Republic. The boy died of scarlet fever in 1887, and was buried under ground in a cemetery in an unknown coffin shortly after death. His parents exhumed his cadaver and entombed it in the family crypt in two tin coffins a year later. This secondary burial and violent opening of the coffins in the end of the World War II leaving the body exposed to external climatic conditions led to its natural (spontaneous) dry mummification. The computed tomography scan of the corpse showed that the majority of internal organs were well preserved. And surprisingly, parts of the central nervous system estimated to be about 70% of the original size with distinguishable neural structures. We tested the cerebellum, tentorium and hair for mercury and arsenic, and the body was assessed by a forensic examiner for possible signs of an artificial embalming, and pathology. We did not confirm the hypothesis of the eventual preservation using the salts of mercury and/or arsenic or other fixation common for embalming in the 1800s. The anthropogenic mummification can be excluded due to the presence of fly larvae, historical records confirmed the burial of the individual right after death, and the different degree of organs condition. It appears that the unique preservation of the mummy and its internal organs was most likely caused by stable conditions of the environment.Intramolecular hydroarylation via C-H activation is one of the most powerful methods to synthesize carbo- and heterocyclic compounds, whereas we still have room for developing a highly enantioselective variant of the reaction. Here we describe Ir-catalyzed enantioselective intramolecular hydroarylation of m-allyloxyphenyl ketones. The enantioselective cyclization was efficiently catalyzed by a cationic iridium complex coordinated with a conventional chiral bisphosphine ligand to give benzofurans in high yields with high enantioselectivity. A carbonyl group of ketones functioned as an effective directing group for the C-H activation. In terms of synthetic utility, we also achieved one-pot synthesis of chiral 3-substituted dihydrobenzofurans from readily available allylic carbonates and m-hydroxyacetophenones via sequential Pd-catalyzed allylic substitution and Ir-catalyzed intramolecular hydroarylation.Correction for 'Synergistic effect in improving the electrical conductivity in polymer nanocomposites by mixing spherical and rod-shaped fillers' by Fan Qu et al., Soft Matter, 2020, 16, 10454-10462, DOI .Single-component nanoplatforms combined with the second near-infrared optical window (NIR-II, 1000-1700 nm) fluorescence imaging (FI) and NIR-II photothermal therapy (PTT) have received increasing attention owing to their capacity for precise diagnosis, noninvasive therapy, and real-time monitoring of the therapeutic effects. However, most of the PTT treatments are performed in the NIR-I window (700-900 nm). Moreover, the design and development of conjugated polymers (P1, P2, and P3) with both bright NIR-II fluorescence and superior NIR-II photothermal effect remained a huge challenge. Therefore, three double-acceptor conjugated polymers were designed and developed by adjusting the molar ratios of two acceptors, TTQ and DPP. Subsequently, their corresponding nanoparticles were fabricated, and finally, nanoparticles based on the conjugated polymer P1 (P1 NPs) with both high NIR-II fluorescence intensity and superior NIR-II photothermal efficiency were selected and applied for NIR-II FI and NIR-II PTT. Importantly, the experiments of in vivo NIR-II FI and NIR-II PTT demonstrated that P1 NPs exhibited not only high accumulation in the tumour sites and high sign-to-background ratio (SBR) of vascular imaging, but also superior NIR-II PTT efficiency for tumour treatment.Stress transmission in realistic granular media often occurs under external load and in the presence of boundary slip. We investigate shear localization in a split-bottom Couette cell with smooth walls subject to a confining pressure experimentally and by means of numerical simulations. https://www.selleckchem.com/products/740-y-p-pdgfr-740y-p.html We demonstrate how the characteristics of the shear zone, such as its center position and width, evolve as the confining pressure and wall slip modify the local effective friction coefficient of the material. For increasing applied pressure, the shear zone evolves toward the center of the cylinder and grows wider and the angular velocity reduces compared to the driving rate of the bottom disk. Moreover, the presence of slip promotes the transition from open shear zones at the top surface to closed shear zones inside the bulk. We also systematically vary the ratio of the effective friction near the bottom plate and in the bulk in simulations and observe the resulting impact on the surface flow profile. Besides the boundary conditions and external load, material properties such as grain size are also known to influence the effective friction coefficient. However, our numerical results reveal that the center position and width of the shear zone are insignificantly affected by the choice of the grain size as far as it remains small compared to the radius of the rotating bottom disk.Aging induces drastic changes in muscle mass and function (sarcopenia); however, the detailed mechanisms underlying sarcopenia remain poorly understood. Recent studies suggested that age-related increases in oxidative stress induce muscle atrophy. In this study, we investigated the effect of 6-month supplementation of antioxidants, specifically piceatannol (PIC) and enzymatically modified isoquercitrin (EMIQ), on age-related physiological changes, including skeletal muscle weight and quality, in 25-month-old (OLD) mice, compared to in 4-month-old (young, YNG) C57BL/6J mice. Muscle weight corrected by body weight significantly declined in OLD mice, compared to in YNG mice. The control OLD mice also showed changes in the expression of genes related to muscle fiber type, reduced locomotor activity, and increased oxidative stress markers in blood. Consistent with the muscle weight and quality changes, whole-body fat oxidation during sedentary conditions and exercise periods in control OLD mice was significantly lower than that in YNG mice.
