مستخلص: Investigating the effects caused by different fire frequencies on the tissue thickness of vegetative organs and the concentration of starch reserves of an invasive species in these same organs could elucidate some gaps, or be the first step towards future, further studies. In such a way, the results can contribute to understanding this species resistance mechanisms related to abiotic stress. This study aimed to understand whether fire frequency in invaded areas by Urochloa brizantha(A.Rich.) R.D.Webster caused anatomical and physiological changes in this species. Twelve samples were collected per fire treatment in areas with different event frequencies: fire exclusion, annual and biennial fires. Anatomical, histochemical and physiological analysis were performed on the leaves, rhizomes and roots. Our anatomical results showed that there was an increase in the thickness of the vascular bundle of U. brizanthaleaves in the treatment of biennial burning. There were no anatomical differences in the roots. In the rhizomes, epidermis of the burned plants had greater thicknesses, the parenchyma and the vascular bundle of the biennially burned plants were more spherical than in unburned plants and in plants burned annually. These anatomical changes in grass tissues in response to fire have not yet been reported in the literature. In the physiological analyses, we found differences in the starch concentrations, with the different organs, the root presented more than 60% of the starch stored in the entire plant. Fire is changing the anatomy of this species, since there was an increase in the thickness of leaf tissues and also in rhizome tissues. The concentrations of starch in the root guaranteed plant to rapidly resprout after burning, which could be considered an advantage in post-fire environments to occupy rapidly the open spaces.

مستخلص: Copper is an essential plant micronutrient, vital in physiological processes. However, excessive copper concentrations can lead to toxicity, adversely impacting biomass accumulation. This study aimed to investigate the effects of toxic copper doses on establishing Rhizobium nodulation, biomass accumulation capacity, and anatomical changes in leaves and roots of Calopogonium mucunoidesplants. The hypothesis was that C. mucunoidesplants could sustain growth even under toxic copper doses and exhibit anatomical alterations after 45 days of cultivation. Soil contamination was conducted using copper sulfate at various doses: 0 (control), 30, 60, 120, 240, and 480 mg dm−3. Root, nodule, and shoot dry mass values were obtained by drying and weighing the plants after 72 h. For anatomical analysis, samples were fixed in 70% FAA, dehydrated using an ethyl series, and embedded in historesin. Slides were stained with toluidine blue, and histochemical tests were performed. No anatomical changes were observed in the leaves across all analyzed tissues. However, in the roots, a decrease in xylem and secondary phloem thickness was observed at the dose of 30 mg dm−3, while an increase in vessel element thickness was observed at the doses of 60 and 120 mg dm−3. Histochemical tests revealed the presence of compounds such as starch and pectins in both leaves and roots, as well as lipids at the base of the tector trichomes in the leaves. C. mucunoidesdemonstrated the ability to maintain growth and nodulation at concentrations of up to 120 mg dm−3of copper in the soil, with impaired growth observed at higher doses.

مستخلص: The literature shows that nocturnal enuresis is not an isolated phenomenon of urinary loss during sleep, but encompasses a set of systemic clinical manifestations that significantly influence children's quality of life and development. However, the understanding of the clinical and physiological relationship of these systemic manifestations remains a clinical challenge. The recognition of these manifestations and their subsequent categorisation, may provide better insights into integrated clinical manifestations, facilitating the understanding of pathophysiological mechanisms, and promote increased assertiveness in the assessment and the selection of appropriate therapies. The aim of this study is to develop a phenotyping model for children with nocturnal enuresis based on evidence. This study presents a clinical phenotyping model for children with nocturnal enuresis based on an analytical and methodological review of the literature, about nocturnal enuresis and its associated clinical manifestations. There was a bibliometric analysis carried out to better analyse outcomes. After reading and analysing the literature, the clinical manifestations were categorised into domains and submitted to the validation of an expert committee with extensive experience in their specific area of expertise. A visual representation of the categorised model was developed to make the phenotyping concept easily understandable to all professionals. The clinical manifestations related to nocturnal enuresis have been categorised according to frequency and relation found in the literature and validation by an expert committee and the development of the phenotyping model for children with nocturnal enuresis was completed. The present study developed an evidence-based phenotyping model for children with nocturnal enuresis. [Display omitted] [ABSTRACT FROM AUTHOR]

مستخلص: Soil contamination by toxic elements due to anthropic impacts negatively affects biodiversity. Some of these elements in low concentrations are micronutrients for plants, such as boron (B). This element plays a key role in various plant functions, including cell wall formation, maintenance of the structural and functional integrity of biological membranes. Calopogonium mucunoidesis a herbaceous legume found in the Cerrado that is used for green manure and tolerates high concentrations of several metals. The morphophysiological and anatomical responses of this species have not yet been evaluated. The objective of this work was to characterize the anatomical alterations in leaves and roots of C. mucunoidescaused under varying but high concentrations of B in the soil. The following concentrations of B: 0 (control), 30, 120 and 480 mg dm−3were used. Anatomical changes were observed in the abaxial epidermis of leaves when exposed to a concentration of 30 mg dm−3. The roots showed changes in the primary xylem also at the concentration of 30 and the concentration of 480 mg dm−3affects the development of secondary tissue growth. Starch grains were detected in the parenchyma in leaves and roots, demonstrating cell wall protection by pectic substances and lipids at the base of the trichome. The defense mechanisms that the species uses to confer tolerance are not yet known and the present results may help provide an anatomical basis to corroborate other sources of evidence and biomarkers that this species can use for phytoremediation processes.

مستخلص: The extent knowledge management literature considers the influence of culture on job satisfaction and knowledge behaviour as vital to organisational performance. However, the specific relationships between these variables has not yet been described and empirically verified in a comprehensive model. This study aims to describe the detailed theoretical relationships between organisational culture job satisfaction, knowledge sharing, and knowledge management maturity and tests them empirically in a comprehensive structural equation model. To achieve this research's objective, descriptive, quantitative research was employed with the use of survey data from 306 respondents of a Brazilian public university. The results support our expectation that culture is a mayor driver of the maturity of knowledge and that this relationship is mediated by knowledge sharing and job satisfaction. We also find that culture and job satisfaction influence knowledge sharing with subsequent positive effects on knowledge management maturity. Our findings inform knowledge management theory and practice on the role of culture in enabling better results in knowledge management.

مستخلص: Hibalactone (HB) is a lignan related to the anxiolytic-like effects of Hydrocotyle umbellataL. However, there is a need to understand better the mechanism of action of this lignan to support the ethnopharmacological uses of the species. This work aimed to evaluate by in vivoand in silicoanalysis the mechanism of action of HB involved in its anxiolytic-like effects.
