title: Interplay between the RNA Chaperone Hfq, Small RNAs and Transcriptional Regulator OmpR Modulates Iron Homeostasis in the Enteropathogen Yersinia enterocolitica

description: Iron is both essential for and potentially toxic to bacteria, so the precise maintenance of iron homeostasis is necessary for their survival. Our previous study indicated that in the human enteropathogen Yersinia enterocolitica, the regulator OmpR directly controls the transcription of the fur, fecA and fepA genes, encoding the ferric uptake repressor and two transporters of ferric siderophores, respectively. This study was undertaken to determine the significance of the RNA chaperone Hfq and the small RNAs OmrA and RyhB1 in the post-transcriptional control of the expression of these OmpR targets. We show that Hfq silences fur, fecA and fepA expression post-transcriptionally and negatively affects the production of FLAG-tagged Fur, FecA and FepA proteins. In addition, we found that the fur gene is under the negative control of the sRNA RyhB1, while fecA and fepA are negatively regulated by the sRNA OmrA. Finally, our data revealed that the role of OmrA results from a complex interplay of transcriptional and post-transcriptional effects in the feedback circuit between the regulator OmpR and the sRNA OmrA. Thus, the expression of fur, fecA and fepA is subject to complex transcriptional and post-transcriptional regulation in order to maintain iron homeostasis in Y. enterocolitica.

title: Lateral and Vertical Diffusion of Magnesium in Ion-Implanted Halide Vapor Phase Epitaxy Gallium Nitride

description: The paper is oriented on magnesium diffusion in gallium nitride samples implanted with this element. This is an importnt issue in the production chain of GaN-based electronics. Both vertical and lateral diffusion is considered.abstract:In the present study, the diffusion of magnesium in gallium nitride was investigated. In order to ensure high structural quality and purity of the analyzed material, bulk crystals, grown by Halide Vapor Phase Epitaxy on ammonothermal native seeds, were used. Samples of polarity (0001), (10-10) and (11-20) were prepared from them and implanted with magnesium ions with fluence of 1×1016 cm-2 and 230 keV energy. X-ray diffraction was used to assess the structural quality of the samples at each stage of the study. Ultra-high-pressure annealing was carried out in the temperature range of 1250-1450°C to activate the dopant and remove post-implantation damage. Diffusion of the implanted species was a consequence of the annealing process. Secondary ion mass spectrometry was used to assess the in-depth concentration of magnesium in the annealed samples. Strong diffusion anisotropy was observed for the crystallographic directions analyzed, with [000-1] being the most susceptible to diffusion and [10-10] being the most resistant. Using the finite element method for numerical analysis of the measured profiles, the diffusion coefficients were determined. Substitutional diffusion involving gallium vacancies was found to be the dominant mechanism in the analyzed samples. The temperature-independent diffusion coefficient was calculated. Its value was 1.7×10-4 cm2/s for the [0001] direction and one order of magnitude less for non-polar directions. The activation energy was similar for all cases studied and ranged from 2.26 eV to 2.38 eV.abbreviations:XRD - X-ray diffractionSIMS - secondary ion mass spectrometryMg - magnesiumH - hydrogen

title: Local chronologies of horse chestnut from forest and mid-field habitat, Krzymów (NW Poland)

description: The horse chestnut (Aesculus hippocastanum L.) has been cultivated in Poland for nearly 400 years. It is frequently planted in urban spaces, along streets, in parks, within residential districts, as well as along roads in open landscape, and in historic palace gardens. The studied avenue of the horse chestnut trees is located along a local road to Krzymów, a village in NW Poland, Western Pomeranian Voivodeship (52.9824869 N, 14.3481286 E, 45-50 m a.s.l.). The avenue was planted in the 2nd decade of the 20th century. The trees forming the avenue (2.5 km long, east-west trending) are growing in a mid-field habitat (FIELD) and in a forest habitat (FOREST), which enables a comparison among trees growing in these habitats. Dendrometric analyses were performed on 100 trees, and dendrochronological analyses were performed for 32 trees, with equal number of trees sampled in each habitat. The FIELD chronology spans 103 years (1916-2018, EPS&gt;0.85: 1922-2018), the FOREST chronology spans 101 years (1918-2018, EPS&gt;0.85: 1929-2018). The average tree-ring width equals 2.82 mm, ranging from 1.56 to 3.31 mm (Table 1).Files with data of horse chestnut tree-ring width and horse chestnut local chronologies (FIELD and FOREST chronology): 1st column - year, 2nd column and next - tree-ring width of individual trees in mm (tree1, tree2, …), next column - local chronology in mm (bold numbers), last column - number of samples in a given year.

title: Plasma free amino acids in high-performance athletes during exercise and recovery

description: The dataset is a part of the project "The effect of long-lasting adaptation to intensive speed-power and endurance training on plasma free amino acids concentration at rest, during graded exercise and post-exercise recovery" funded by the National Science Center Poland, grant OPUS 14, recipient: Krzysztof KusyThe dataset includes measurement data from a graded exercise test until exhaustion. Before, during, and after the test, venous blood samples were taken and plasma free amino acids concentrations assayed as affected by exercise intensity and the recovery phase (LC-ESI-MS/MS technique and the aTRAQTM reagent). A series of secondary variables were also determined for description and data interpretation. The measurements were performed in the pre-competition period of a one-year training cycle, i.e. when athletes approached the highest level of physiological adaptation specific to their disciplines. Exercise testing, body composition measurements, and blood draws were conducted at the Human Movement Laboratory "LaBthletics" of the Poznan University of Physical Education, Poznan, Poland. Plasma samples for amino acids assay were analyzed in the Department of Inorganic and Analytical Chemistry of the Poznan University of Medical Sciences, Poznan, Poland.

title: Dataset from the analysis of the dielectric and calorimetric response of anisotropic sizable glass-forming isomers differing in the position of the –CF3 group attached to the phenyl ring.

description: This dataset contains dielectric and calorimetric data published in the article entitled “The influence of molecular shape on reorientation dynamics of sizable glass-forming isomers at ambient and elevated pressure” (DOI). The raw data provided contain results collected for three glass-forming isomers (referred to as meta-CF3, ortho-CF3, para-CF3) having the same non-polar sizable core, composed of diphenylamine, fluorene, and alkyl chains, connected to a phenyl ring substituted variously with -CF3 group. These data correspond to Figures 2-11 published in the article (https://link). Raw data were generated during measurements using (1) broadband dielectric spectroscopy (BDS) over a wide range of temperatures and pressures (BDS), (2) differential scanning calorimetry (DSC), and (3) temperature-modulated differential scanning calorimetry (TMDSC).

The work was conducted to determine the source of triangular planar defects visible in X-ray topography as areas with locally different lattice parameters. It is shown that the occurrence of these defects is related to growth hillocks. Particular attention was paid to analyzing the manner and consequences of merging hillocks. In the course of the study, the nature of the mentioned defects and the cause of their formation were determined. It was established that the appearance of the defects depends on the angle formed between the steps located on the sides of two adjacent hillocks. A universal growth model is presented to explain the cause of heterogeneity during the merging of growth hillocks.
