The exchange of information between appliers of mental health interventions is essential to guarantee effective program implementation. The study aimed to examine how individual and group factors influence the exchange of information among the implementers of a psychosocial intervention program targeted to victims of the war in Colombia. A cross-sectional exploratory design was developed. Interviews were held with 18 psychologists, 22 social workers, 10 community promoters, and a nurse. The study used the E-i index and the visualization of interclass and intraclass links. There is no homophilic tendency in the exchange of information among the three professional categories. Empowerment predicts the nominations received in the request for information network (β = 0.296, p less then 0.006). To be central in the preference network is the principal predictor of receiving requests for information (β = 0.562, p less then 0.0001). Empowered professionals and those who exchange information on the implementation process are considered key informants that can improve the program's effectiveness.This study describes the synthesis and antioxidant activity of new 1,4-disubstituted 1,2,3-triazoles. These compounds were generated semi-synthetically using the Cu(I)-catalysed azide-alkyne cycloaddition (CuAAC) reaction between ethyl 2-azidoacetate and terminal acetylenes derived from the natural products carvacrol, eugenol, isovanillin, thymol and vanillin. The products were obtained at 50 to 80% yield and characterised through several spectrographic techniques. Antioxidant activity was assayed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS). The products exhibited moderate antioxidant activity, with ethyl 2-(4-((4-formyl-2-methoxyphenoxy)methyl)-1H-1,2,3-triazol-1-yl) acetate showing the highest antioxidant capacity (EC50 = 75.5 µg/mL) among the generated 1,4-disubstituted 1,2,3-triazoles. In conclusion, the generation of these compounds opens new possibilities for the development of new antioxidant agents.Cytosporones, a class of octaketide resorcinolic lipids, have drawn the attention of researchers for exhibiting a number of notable biological properties. Herein, we describe routes to synthesize the bioactive synthetic resorcinolic lipids AMS35AA and AMS35BB with excellent overall yields using 3,5-dimethoxybenzoic acid as the starting material. The methods proved remarkably efficient to achieve the target compounds and comprise the synthesis of AMS35AA catalyzed by ascorbic acid (vitamin C).An endophytic bacterium inhibiting pathogenic bacteria was isolated and the strain was genetically identified as Paenibacillus polymyxa. Biochemical characterization of fermentation broth indicated the presence of peptidic antimicrobial molecules. Liquid-liquid partition resulted in an organic fraction (OF) and an aqueous fraction (AF). OF presented a broad spectrum of activity against a panel of pathogenic bacteria and a fungus whereas the AF was active only against Gram-negative bacteria. AF was sequentially submitted to ion-exchange, desalting and reverse phase (RP) chromatography. A molecule with an RT of 2.45 min exhibited activity against all Gram-negative pathogenic strains tested beside P. mirabilis. The primary structure of the molecule, named AMP-Pp, was determined as Gly-Glu-Hyp-Gly-Ala by N-terminal sequencing. The molecular mass and amino acid sequence were confirmed by MS/MS. With a molecular mass of 463 Da, AMP-Pp is one of the smallest active natural peptides reported, yet. RP chromatography of OF resulted in four peaks. The first three peaks corresponded to known antimicrobials. MS analysis of peak 4 revealed the presence of an ion with m/z 3,376.4 Da, whose proposed molecular formula is C182H321N29O29. The compound, named polycerradin, showed a spectrum of activity against Gram-positive bacteria, Gram-negative bacteria (beside P. mirabilis) and a fungus.Vuralia turcica (Fabaceae; Papilionoideae) is a critically endangered endemic plant species in Turkey. This plant grows naturally in saline environments, although the photosynthesis and physiological functions of many plants are affected by salt stress. Molecular control mechanisms and identification of genes involved in these mechanisms constitute the critical field of study in plant science. Trehalose-6-phosphate synthase (TPS) is one of the essential enzyme genes involved in trehalose biosynthesis, which is protective against salt stress. Also, the vacuolar Na+/H+ antiporter gene (NHX) is known to be useful in salt tolerance. selleck inhibitor In this study, the TPS and NHX-like genes in V. turcica were partially sequenced using degenerate primers for the first time and submitted to the NCBI database (accession numbers MK120983 and MH757417, respectively). Also, the expression levels of the genes encoding TPS and NHX were investigated. The results indicate that the increase in both the level of applied salt and cadmium is coupled with the increase in the expression level of NHX and TPS genes. However, salt exposure significantly affected the expression level of the NHX gene. The findings suggest that the NHX gene might play a crucial role in the salt tolerance ability of V. turcica.The shape of the secondary sexual characters is, traditionally, used to discriminate the marine shrimps at the species level. However, the qualitative evaluation of structures that are morphologically variable in the taxonomy of species can favor misunderstandings and misidentifications. These possibilities of taxonomic inaccuracies are especially alarming when there is a need to evaluate the invasion of introduced species. The present study used geometric morphometric analyses to identify differences in the cephalothorax shape that would help discriminate the native and non-native species of Litopenaeus of the South American coast. The comparative morphology analysis was conducted using the right profile of adult males' cephalothorax of L. schmitti, captured in the natural environment, and L. vannamei captured in the natural environment or grown in shrimp farms. In intraspecific evaluation, it was not possible to distinguish the specimens of L. vannamei that were grown in shrimp farms from those acclimated to the natural environment.
