DEX treatment increased or rescued hGH-N RNA levels, and was associated with elevated Bmal1 transcripts when assessed 12 h after final treatment, and at a time when serum corticosterone levels were suppressed >90%. In addition, a diet-dependent effect on hGH-N RNA levels was observed at 36 h after final treatment, but only in the light stage, presumably due to residual effects of DEX treatment and/or recovery of endogenous corticosterone levels. This is the first evidence for a direct effect of GCs on hGH-N expression in vivo and the ability to potentially limit the negative effect of overeating/obesity on hGH production in puberty.Gray blight disease is a serious disease of tea (Camellia sinensis (L.) Kuntz), for which there is currently no effective control or preventative measure apart from fungicides. Screening for effectiveness of a natural anti-microbial against this pathogen and identifying its mode of action could contribute to the management of this disease. Antifungal activity of the anti-microbial Ningnanmycin (NNM) from Streptomyces noursei var. xichangensis against the pathogen causing gray blight disease, Pseudopestalotiopsis camelliae-sinensis (F. NVPBHG712 Liu & L. Cai) strain GZHS-2017-010 was confirmed in vitro by the mycelial growth rate method. Optical microscopy, scanning electron microscopy and transmission electron microscopy were used to observe morphological change of hyphae of Ps. camelliae-sinensis treated with NNM. RNA sequencing, bioinformatics and quantitative real-time PCR were used to identify genes in the hyphae which were differentially expressed in response to treatment with NNM. Thirty-eight genes from sixteen pathways, known as targets of antifungal agents, were used to investigate gene expression in hyphae at the half-maximal effective concentration (EC50) dosage, EC30, and EC70 for 1, 7, or 14 h. The results indicated that NNM can inhibit the growth of hyphae in vitro, with an EC50 of 75.92 U/mL, inducing morphological changes in organelles, septa, and extracellular polysaccharides, targeting ribosomes to disturb translation in protein synthesis, and influencing some biosynthetic functions of the hyphae.The BigDFT project was started in 2005 with the aim of testing the advantages of using a Daubechies wavelet basis set for Kohn-Sham (KS) density functional theory (DFT) with pseudopotentials. This project led to the creation of the BigDFT code, which employs a computational approach with optimal features of flexibility, performance, and precision of the results. In particular, the employed formalism has enabled the implementation of an algorithm able to tackle DFT calculations of large systems, up to many thousands of atoms, with a computational effort that scales linearly with the number of atoms. In this work, we recall some of the features that have been made possible by the peculiar properties of Daubechies wavelets. In particular, we focus our attention on the usage of DFT for large-scale systems. We show how the localized description of the KS problem, emerging from the features of the basis set, is helpful in providing a simplified description of large-scale electronic structure calculations. We provide some examples on how such a simplified description can be employed, and we consider, among the case-studies, the SARS-CoV-2 main protease.We study the exciton localization and resulting optical response for disordered tubular aggregates of optically active molecules. It has previously been shown that such tubular structures allow for excitons delocalized over more than a thousand molecules, owing to the combined effects of long-range dipole-dipole interactions and the higher-dimensional (not truly one-dimensional) nature of the aggregate. Such large delocalization sizes prompt the question to what extent in experimental systems the delocalization may still be determined by the aggregate size (diameter and length) and how this affects the aggregate's optical response and dynamics. We perform a systematic study of the size effects on the localization properties using numerical simulations of the exciton states in a cylindrical model structure inspired by the previously derived geometry of a cylindrical aggregate of cyanine dye molecules (C8S3). To characterize the exciton localization, we calculate the participation ratio and the autocorrelation function of the exciton wave function. We also calculate the density of states and absorption spectrum. We find strong effects of the tube's radius on the localization and optical properties in the range of parameters relevant to the experiment. In addition, surprisingly, we find that even for tubes as long as 750 nm, the localization size is limited by the tube's length for disorder values that are relevant to experimental circumstances, while observable effects of the tube's length in the absorption spectrum still occur for tube lengths up to about 150 nm. The latter may explain the changes in the optical spectra observed during the aging process of bromine-substituted C8S3 aggregates. For weak disorder, the exciton wave functions exhibit a scattered, fractal-like nature, similar to the quasi-particles in two-dimensional disordered systems.Liquid state theories such as integral equations and classical density functional theory often overestimate the bulk pressure of fluids because they require closure relations or truncations of functionals. Consequently, the cost to create a molecular cavity in the fluid is no longer negligible, and those theories predict incorrect solvation free energies. We show how to correct them simply by computing an optimized Van der Walls volume of the solute and removing the undue free energy to create such volume in the fluid. Given this versatile correction, we demonstrate that state-of-the-art solvation theories can predict, within seconds, hydration free energies of a benchmark of small neutral drug-like molecules with the same accuracy as day-long molecular simulations.An application of the continuous transformation of the origin of the current density (CTOCD) scheme to constrain the diamagnetic induced charge current density (Jd) to be divergenceless is introduced. This results in a family of Jd fields perpendicular and proportional to both the gradient of the electron density and the external magnetic field. Since, in the limit of a complete basis set calculation, the paramagnetic component Jp also becomes divergenceless, we call this scheme CTOCD-DC (CTOCD for Divergenceless Components). CTOCD-DC allows for a topological characterization of both Jd and Jp in terms of their stagnation graphs. All stagnation graphs of Jd from CTOCD-DC contain the zero points of the gradient of the unperturbed electron density (∇ρ). In this way, an intimate topological relation between ρ and the diamagnetic current contribution is revealed. Numerical experiments exemplified by the case of LiNHF in point group symmetry C1 suggest that the corresponding paramagnetic current contributions Jp can show tendencies to accumulate pseudo-stagnation lines in proximity of some kind of the zero points of ∇ρ.
