Among stimulant drugs, cocaine deserves attention due to its high rates of seizures worldwide. This work presents the synthesis and characterization of hybrid molecularly imprinted polymers (MIPs) for use in preparing biological samples using a homemade microextraction in a packed sorbent device to extract cocaine. The MIPs synthesized using caffeine and cocaine as templates have been compared. Caffeine was used due to its low value and be easier to obtain than cocaine. Additionally, restricted access molecularly imprinted polymers (RAMIPs) were also produced for comparison purposes. The polymeric materials were characterized using scanning electron microscopy, textural analysis, Fourier transform infrared spectroscopy, and cross polarization/ magic angle spinning 13C nuclear magnetic resonance. The method optimization was performed using linear ion trap mass spectrometer to evaluate the effects of sample pH, type of eluent, washing solvent, adsorption cycles, and eluent volume. In the optimized method, RAMIPs indicated better cocaine extraction compared to MIPs. The quantitative study demonstrated that the developed method was able to accurately quantify cocaine in urine samples with values close to actual concentrations. drugs worldwide (MIPs Additionally (RAMIPs purposes microscopy analysis spectroscopy polarization C resonance pH solvent cycles volume concentrations

Hematological problems are associated with Coronavirus disease 2019 (COVID-19). Respiratory impairment is the higher point studied, although without experimental studies related to the oxygen transport performed by erythrocytes. Therefore, we decided to investigate if erythrocytes from COVID-19 patients have their functionality changed. The case-control study included hospitalized patients with a positive real-time polymerase chain reaction (RT-PCR) result admitted to University Hospital. Volunteers (negative RT-PCR results) were recruited as a control group. Thus, we assessed different erythrocytes parameters, oxidative stress markers, and biophysical studies using whole blood and isolated hemoglobin. We found a decrease of 51% in oxygen uptake and reduced antioxidant enzyme activity in COVID-19 patients compared to controls. Raman spectrometry showed structural changes in the hemoglobin and lipids of the erythrocytes from COVID-19 patients; thus, these results were consolidated with an increase in Young’s modulus in erythrocytes followed by morphology changes. Besides, isolated hemoglobin from COVID-19 patients has a distinct interaction profile using a ligand model compared to the control. COVID-19 leads to structural, functional, and morphological damage to human erythrocytes. Our data showed structural and molecular changes and induction of oxidative stress in erythrocytes by COVID-19, a new perspective on the contribution of erythrocytes to a respiratory commitment in COVID-19.

ABSTRACT Organic residue in the substrate and the availability of light influence the production of high-quality seedlings for ex situ cultivation of native forest species. This study aimed to evaluate the effect of doses of chicken manure incorporated in the soil and shading levels on the morphophysiological responses and quality of Alibertia edulis (Rich.) A. Rich seedlings. Five doses of chicken manure (CM) were tested, 0.00, 2.08, 4.16, 6.24, and 8.32 g CM kg-1 soil, under two shade conditions, 0% (full sun) and 50% shading. At 215 days after transplanting, the maximum height obtained for A. edulis was 47.35 cm with 5.64 g CM kg-1 soil under 50% shade. Shaded seedlings had a higher number of leaves. The maximum leaf and root areas were 796.64 and 118.83 cm2 with 5.32 and 4.21 g CM kg-1 soil, respectively, both under 50% shade. Seedlings in 0% shade had lower physiological indices. Shading levels did not affect stomatal limitation, but CM contributed to physiological efficiency. Shoot biomass was higher under 50% shade with higher CM doses. The highest quality indexes occurred with 3.98 and 6.28 g kg-1 CM under 0 and 50% shade, respectively. A. edulis seedlings responded positively to the addition of CM to the soil and presented plasticity under contrasting light conditions. A. edulis seedlings produced under 50% shading with the addition of 6.24 g CM kg-1 soil presented high morphophysiological and seedling quality indicators. The addition of 4.32 g CM kg-1 soil contributed to high seedling quality under full sun conditions.

RESUMO O uso de resíduo orgânico no substrato e a disponibilidade de luz influenciam na obtenção de mudas de elevada qualidade para o cultivo ex situ de espécies florestais nativas. Objetivou-se com este estudo avaliar o efeito de doses de cama de frango incorporadas ao solo e níveis de sombreamento sobre as respostas morfofisiológicas e qualidade de mudas de Alibertia edulis (Rich.) A. Rich. Foram estudadas cinco doses de cama de frango (CF): 0,00; 2,08; 4,16; 6,24 e 8,32 g kg-1 sob duas condições de sombreamento: 0% (pleno sol) e 50% de sombreamento. Aos 215 dias após o transplantio, a máxima altura da A. edulis foi 47,35 cm com 5,64 g CF kg-1 solo sob 50% de sombreamento. Mudas sombreadas tiveram maior número de folhas. A máxima área foliar e radicular foi de 796,64 e 118,83 cm2 com 5,32 g e 4,21 g CF kg-1 solo, respectivamente, ambos sob 50% de sombra. Mudas sob 0% de sombra tiveram menores índices fisiológicos. Os níveis de sombreamento não afetaram a limitação estomática, mas a CF contribuiu na eficiência fisiológica. As biomassas da parte aérea foram maiores sob 50% de sombra com maiores doses de CF. Os maiores índices de qualidade ocorreram com 3,98 e 6,28 g CF kg-1 solo sob 0 e 50% de sombra, respectivamente. Mudas de A. edulis responderam positivamente à adição de CF ao solo e apresentaram plasticidade às condições contrastantes de luz. Mudas de A. edulis produzidas em 50% de sombra com adição de 6,24 g CF kg-1 solo apresentaram maiores indicadores morfofisiológicos e qualidade de mudas. A adição de 4,32 g CF kg-1 solo contribuiu na qualidade de mudas sob pleno sol.

ABSTRACT The expression ‘you need to know to conserve’ is a well-known cliche among biologists. Documenting the richness of a group of organisms is the first step towards understanding biodiversity and preparing efficient conservation plans. In this context, many efforts have been made to quantify the number of species on Earth and estimate the number of species still unknown to science. A few countries have complete and integrated databases estimating the approximate number of species recorded for their territory, particularly in the Global South. In Brazil, a country of continental dimensions, revealing the richness of the second most diverse clade of invertebrates (=Mollusca) has been a goal of taxonomists. Recently, in an unprecedented, collective, and integrated effort among Brazilian malacologists, it was possible to estimate how many valid species of molluscs are there in Brazil. In this effort, more than 30 mollusc experts joined together to update the Taxonomic Catalogue of the Brazilian Fauna (TCBF), a governmental website that allows a quick and real-time updating of all Metazoan. So far, more than 5,000 updates have been made in TCBF, indicating the presence of 3,552 valid species of molluscs in Brazil, distributed among the main clades as follows: Caudofoveata (10 spp.), Solenogastres (6 spp.), Polyplacophora (35 spp.), Scaphopoda (43 spp.), Cephalopoda (92 spp.), Bivalvia (629 spp.) and Gastropoda (2,737 spp.). The present study, in addition to demonstrating for the first time the richness of Brazilian molluscs, also presents the state of the art of this important phylum of invertebrates highlighting its most representative and neglected groups.

Abstract Despite the enormous paleobotanical record on different islands of the Antarctic Peninsula, the evidence of insect activity associated with fossilized plants is scarce. Here we report the first evidence of insect-plant interaction from Cretaceous deposits, more precisely from a new locality at the Rip Point area, Nelson Island (Antarctic Peninsula). The macrofossil assemblage includes isolated Nothofagus sp. leaf impressions, a common component of the Antarctic paleoflora. Two hundred leaves were examined, of which 15 showed evidence of insect activity, displaying variations in size, shape, and preservation. Two types of interaction damage, galls and mines, were identified. A single specimen retained a circular scar recognized as galling scar, while meandering tracks were considered mines. These traces of herbivore insect activity, correspond to the oldest known record of this type of interaction of West Antarctica and the oldest record of insect-plant interaction in Nothofagus sp. reported so far.

RESUMO A análise da fluorescência da clorofila é uma das muitas formas de quantificar o dano salino no desempenho fotossintético e na produção agrícola. Assim, o presente estudo teve como objetivo avaliar a eficiência fotoquímica e a produção do coentro, cultivar Verdão em função dos níveis de condutividades elétricas da solução nutritiva e da natureza catiônica. O delineamento experimental foi em blocos ao acaso, em esquema fatorial 4 × 3, com quatro repetições. Os tratamentos consistiram na exposição das plantas a quatro condutividades elétricas das soluções nutritivas (CEsn = 1,6; 3,2; 4,8 e 6,4 dS m-1) e três tipos de águas de diferentes naturezas catiônicas (Na+; Ca2+; Mg2+), preparadas com a solubilização de diferentes sais - NaCl, CaCl2.2H2O e MgCl2.6H2O em água de abastecimento da UFRPE (CEa = 0,12 dS m-1). O estudo foi realizado em casa de vegetação entre novembro e dezembro de 2019 no Laboratório de Fertirrigação e Salinidade do Departamento de Engenharia Agronômica da Universidade Federal Rural de Pernambuco. O aumento da condutividade elétrica da solução nutritiva afetou os centros de reação, a atividade fotoquímica, a eficiência da carboxilação e resultou na redução da condutância estomática, da taxa de assimilação de CO2 e, portanto, na produção de biomassa do coentro. Diferentes prevalências catiônicas na água proporcionam diferenças na intensidade do dano salino, sobretudo com o aumento da concentração.

ABSTRACT The analysis of chlorophyll fluorescence is one of many ways to quantify the salt damage to photosynthetic performance and crop production. Thus, the present study aimed to evaluate the photochemical efficiency and production of coriander, cultivar ‘Verdão’, as a function of the electrical conductivity levels of the nutrient solution and the cationic nature. The experimental design was in randomized blocks, in a 4 × 3 factorial scheme, with four replicates. The treatments consisted of four electrical conductivities of the nutrient solutions (ECns = 1.6, 3.2, 4.8, and 6.4 dS m-1) and three kinds of water of different cationic natures (Na+; Ca2+; Mg2+), which were prepared with the dissolution of different salts - NaCl, CaCl2.2H2O, and MgCl2.6H2O in supply water (ECw = 0.12 dS m-1), that is, three predominant cationic natures. The study was carried out in a greenhouse between November and December 2019 at the Fertigation and Salinity Laboratory of the Agricultural Engineering Department of the Universidade Federal Rural de Pernambuco. It was found that the increase in the electrical conductivity of the nutrient solution affected reaction centers, photochemical activity, and carboxylation efficiency and resulted in reductions in stomatal conductance, CO2 assimilation rate, and therefore, in the biomass production of coriander. Different cationic prevalence in water causes differences in the intensity of salt damage, especially with increasing concentration.

Objectives: Past suicide attempt (SA) is one of the most important risk factors for suicide death. An ideation-to-action framework posits that impulsivity, potentially traumatic events, and mental disorders also play a role in increasing suicide risk. This study aimed to assess the association between trait impulsivity, lifetime exposure to trauma, and post-traumatic stress disorder (PTSD) with SA in a sample of Brazilian college students. Methods: A total of 2,137 participants filled self-reported questionnaires consisting of a sociodemographic and clinical questionnaire, Trauma History Questionnaire, Post-Traumatic Stress Disorder Checklist – Civilian version, and Barratt Impulsiveness Scale. Results: Our findings suggest that trait impulsivity may be interpreted as exerting a distal effect on SA, even in the presence of other variables – such as trauma history, psychological neglect, and PTSD – which also increase the odds of SA. High and medium levels of impulsivity, history of trauma, and PTSD increased the likelihood of SA. Conclusions: Intervention strategies to prevent SA may target trait impulsivity and exposure to traumatic experiences.

In recent years, there has been an increasing interest in the development of antimicrobial materials for different applications, especially in the biomedical field. In this context, chitosan is one of the most employed materials due to its highly attractive properties, such as biocompatibility, biodegradability, non-toxicity, and antimicrobial activity against gram-negative and gram-positive bacteria and fungi. In this review, we discuss the different methods used to obtain chitosan and point out how they affect the structural and chemical properties of this material, followed by a detailed discussion on how these properties influence its antimicrobial activities. Additionally, we summarize the most accepted antimicrobial mechanisms of action for chitosans. Specifically, we aim to provide a comprehensive overview on the last findings and progress reported in the literature on the factors that influence the antimicrobial activity of chitosan, e.g., polymeric average molecular weight ( M W ¯), average degree of acetylation ( D A ¯), water-soluble derivatization and sample degree of purity. The data available in the literature indicate that in addition to the structural properties, the effectiveness of such antimicrobial activity of chitosan is also dependent on the target microorganisms. This review will help researchers to better understand the mechanism of action of chitosan against microorganisms based on its structural characteristics.

RECENT ADVANCES IN THE SYNTHESIS OF REMDESIVIR, MOLNUPIRAVIR (EIDD-2801) AND TENOFOVIR: PROMISING MOLECULES IN THE TREATMENT OF COVID-19. The search for new treatments to contain the Covid-19 pandemic has highlighted the importance of nucleoside antivirals, such as Remdesivir, Tenofovir and Molnupiravir. Over the last two years, these molecules have been intensely investigated as promising alternatives against SARS-CoV-2 virus. Considering the increasingly demand for those substances, several research groups are intensely investigating synthetic developments in order to obtain these nucleoside derivatives and their intermediates in a fast, efficient and accessible manner. In this context, this review aims to in-depth present the recent advances concerning the preparation of Remdesivir, Tenofovir and Molnupiravir. Aspects involving differences in the starting materials and reagents, as well as the advantages and limitations of each protocol would be carefully disclosed. Moreover, the use of synthetic tools, such as flow chemistry, organocatalysis and biocatalysis, would also be detailed. Finally, this review also presents aspects involving the scale-up of these transformations, including discussions about stereo- and diastereoselectivity, as well as product isolation details. In summary, an overview of the existing synthetic strategies for these active pharmaceutical ingredients (APIs) are presented.

Abstract Antarctic harsh conditions favor the development of microbial adaptations. In this study, a molecular approach was applied to identify/refine the taxonomy of five yeasts isolated from different Antarctic samples, which were tested against ranges of temperature, UV radiations, salinity, and pH. Based on sequencing and phylogenetic analysis, strain CRM 1839 was confirmed as Naganishia sp., and strains CRM 1874, CRM 1565, CRM 2571, and CRM 2576 were identified as Goffeauzyma gilvescens, Goffeauzyma gastrica, Candida atlantica, and Camptobasidium sp., respectively, being this last one possibly a new species. Growth at different temperatures indicates that these yeasts are psychrotolerant, with the exception of Camptobasidium sp., which presents psychrophilic characteristics. G. gastrica recovered from marine sediment showed the best results of resistance to UV radiation, being able to grow even after the exposure to UVB dose of 9144 J/m² and UVC dose of 6102 J/m². C. atlantica isolated from glacier soil showed high cellular growth from 3 to 10% NaCl. The majority of the strains produced higher biomass at pH 7; nevertheless, G. gilvescens showed higher biomass production at pH 9. The studied Antarctic-derived yeasts have adaptations to extreme conditions, which makes them useful for biotechnological applications and studies of extremophiles.

RESUMO: A infecção por Trypanosoma spp. é um problema em muitos países tropicais, infectando várias espécies animais, incluindo humanos. O objetivo do presente estudo foi identificar as espécies de Trypanosoma em primatas neotropicais no estado Rio de Janeiro e comparar os resultados com outros relatos, tanto filogeneticamente quando geograficamente. A detecção molecular foi baseada no gene SSU 18. As sequências obtidas na PCR foram sequenciadas e comparadas com outras previamente depositadas no GenBank. Essas sequências foram utilizadas para análises filogenéticas e confeccionar um mapa de distribuição de espécies de primatas infectadas por espécies de Trypanosoma no Brasil. Entre 34 macacos, cinco macacos-prego (Sapajus spp.) e um sagui (Callithrix spp.) apresentaram sequências de Trypanosoma spp. no mesmo clado de Trypanosoma minasense e três sequências de macacos-prego estavam no mesmo clado de Trypanosoma cruzi. A Mata Atlântica e a Amazônia brasileira são as regiões com maior frequência de estudos sobre Trypanosoma spp. e variedade de primatas neotropicais hospedeiros. São áreas que merecem atenção no que se refere à conservação da biodiversidade, mas também evidencia a carência de estudos com PNH em outras regiões do país e de estudos multidisciplinares para melhor compreender as relações do patógeno hospedeiro.

ABSTRACT: Trypanosoma spp. infection is a problem in many tropical countries, infecting several animal species, including humans. The aim of the present study was to identify the Trypanosoma species in Neotropical primates from Rio de Janeiro state and compare the results with other reports both phylogenetically and geographically. Molecular detection was based on the 18 SSU gene. The sequences obtained in the PCR were sequenced and compared with others previously deposited in GenBank. These sequences were used to perform phylogenetic analysis and make a distribution map of primate species infected by Trypanosoma species in Brazil. Among 34 monkeys, five capuchin monkeys (Sapajus spp.) and one marmoset (Callithrix spp.) showed Trypanosoma spp. sequences in the same clade of Trypanosoma minasense and three capuchin monkeys’ sequences were in the same clade of Trypanosoma cruzi. The Atlantic Forest and the Brazilian Amazon are the regions with the highest frequency of studies about Trypanosoma spp. and variety of Neotropical primate hosts. These are areas that deserve attention regarding the conservation of biodiversity, but it also makes evident the lack of studies with Neotropical primates in other regions of the country, as well as multidisciplinary studies to better understand the host pathogen relationships.

Resumo Objetivo: o cuidado de adolescentes com ou sem doença crônica deve ser completo, padronizado e focado nas demandas individuais e no processo de transição para a assistência ao adulto e adesão ao tratamento. Este estudo teve como objetivo caracterizar a assistência prestada por enfermeiros do estado de São Paulo que atuam com adolescentes. Método: trata-se de um estudo transversal e descritivo sobre a assistência prestada a adolescentes por enfermeiros de São Paulo, a partir das respostas a um questionário autoaplicável, disponível no instrumento REDCap entre agosto de 2018 e outubro de 2019. Resultados: os participantes responderam a 1632 questionários. Apenas 38% dos enfermeiros trabalham com adolescentes, e 11,2% deles de forma exclusiva. Os profissionais foram divididos de acordo com a mediana de tempo de experiência profissional nos Grupos A e B (≤ 5 anos e > 5 anos).

Abstract Objective: the care of adolescents with or without a chronic disease must complete, standardized and focused on individual demands and the transition process to adult care and adherence to treatment. This study aimed to characterize the care provided by nurses from the state of São Paulo who work with adolescents. Method: this is a cross-sectional and descriptive study on the care provided to adolescents by nurses in São Paulo, based on the answers to a self-administered questionnaire, available in the REDCap tool between August 2018 and October 2019. Results: participants answered 1632 questionnaires. Only 38% of nurses work with adolescents, 11.2% exclusively. Professionals were divided according to the median length of professional experience in groups A and B (≤5 years and >5 years). Drug addiction (p=0.01) and working with a multidisciplinary team (p=0.04) were significantly more reported in group B. Routine follow-up (p=0.02) and questioning about sexual or physical violence (p=0.03) were significantly more performed by professionals from group A. Conclusion: this study identified the need for a care protocol that can be replicated on a large scale and that includes the treatment and the particularities of adolescents to improve adherence and the transition into adult care.

Resumen Objetivo: el cuidado de los adolescentes con o sin enfermedad crónica debe ser completo, estandarizado y centrado en las demandas individuales y en el proceso de transición a la atención para adultos y la adherencia al tratamiento. Este estudio tuvo como objetivo caracterizar los cuidados prestados por el personal de enfermería del estado de São Paulo que trabaja con adolescentes. Método: se trata de un estudio transversal y descriptivo sobre los cuidados prestados a los adolescentes por el personal de enfermería de São Paulo, a partir de las respuestas a un cuestionario autoadministrado, disponible en la herramienta REDCap entre agosto de 2018 y octubre de 2019. Resultados: los participantes respondieron a 1.632 cuestionarios. Solo el 38% del personal de enfermería trabaja con adolescentes, el 11,2% de forma exclusiva. Los profesionales se dividieron según la duración media de la experiencia profesional en los grupos A y B (≤5 años y >5 años). La drogadicción (p=0,01) y el trabajo con un equipo multidisciplinar (p=0,04) fueron significativamente más reportados en el grupo B. El seguimiento rutinario (p=0,02) y las preguntas sobre violencia sexual o física (p=0,03) fueron significativamente más realizadas por los profesionales del grupo A. Conclusión: este estudio identificó la necesidad de un protocolo de atención que pueda ser replicado a gran escala y que incluya el tratamiento y las particularidades de los adolescentes para mejorar la adherencia y la transición a la atención de adultos.

ABSTRACT It is essential to determine the productive potential and quality of forage sorghum (Sorghum bicolor (L.) Moench) silages using alternative and organic inputs, such as poultry litter (PL), intending to higher efficiency, and sustainable development of animal production systems in the world. Poultry litter fertilization has been widely used in crops for silage production, where it is believed that fertilization with PL can influence the fermentation profile and composition of forage sorghum silages. The objective of this study was to evaluate different levels of fertilization with PL on the agronomic and quality characteristics of forage sorghum silage ‘BRS Ponta Negra’. For determination of agronomic and productive characteristics, randomized blocks design was adopted, the treatments were different PL levels: 5, 10, and 15 Mg ha-1. While for the evaluation of silage characteristics, the design was completely randomized. With fertilizer doses, a linear increase was observed for plant height, stem diameter, leaf length, and consequently for fresh and DM productions. Linear reduction was observed for neutral detergent fiber, while crude protein and pH contents of silages increased linearly with PL levels. Quadratic effect occurred for gas and effluent losses. Poultry litter may be an alternative source to supply the N needs in the production of sorghum for silage under experimental similar conditions. Associating productivity with cultivation efficiency, the PL level 13.46 Mg ha-1 is recommended for presenting the highest N agronomic efficiency and good nutritional quality of the silage.

The present investigation describes the synthesis of novel cinnamides and a bis cinnamate bearing 1,2,3-triazole functionalities and investigation of their antiproliferative and antimetastatic effects on melanoma cells. The necessity for the development of new chemotherapeutic agents for melanoma treatment motivated this work. Sixteen derivatives were obtained with yields ranging from 23-81% and fully characterized by spectroscopic (1H and 13C nuclear magnetic resonance, infrared) and spectrometric high resolution mass spectrometry (HRMS) techniques. The derivatives were in vitro evaluated against B16-F10 murine melanoma cell line. The most effective compound (a bis cinnamate) (6b) reduced the melanoma cell viability, generated cell cycle arrest, and influenced the metastatic behavior of melanoma cells by decreasing migration, invasion, and colony formation. Based on these findings, it is believed that compound 6b may represent an interesting scaffold to be explored toward the development of new antimelanoma agents.
