Abstract Objective: To describe the changes in alcohol and drug use by Brazilian adolescents during the COVID-19 pandemic (April-August 2021), and to analyze the relationship between alcohol use changes and psychiatric symptomatology. Methods: A secondary analysis with a longitudinal approach was performed with data from a cluster-randomized controlled trial, conductedin73publicmiddleschoolsinthreeBrazilian cities, to evaluate the effectiveness of a drug use prevention program. The sample included 535 students (61% girls; Mage = 15.2 years). Data were collected pre-intervention (February-March 2019), after 9 months (November-December 2019), and after 26 months (April-August 2021), when the students were in their first year of high school. The authors analyzed drug use prevalence (alcohol, binge drinking, tobacco, inhalants, marijuana, cocaine, and crack) in a lifetime, past year, and past month periods, and the association between alcohol use change subsamples with psychiatric symptoms. Logistic regressions were adjusted by sex, age, socioeconomic status, city, and group (control and intervention). Results: The present findings suggest that the COVID-19 pandemic led to a decrease in past-year substance use and in past-month substance use frequency, despite the gradually increased (but decelerating) prevalence of lifetime use. However, some adolescents initiated, maintained, or increased the frequency of their alcohol use. Mainly, they were more likely to present behavioral problems, as well as symptoms of inattentive hyperactivity, and peer and emotional problems. Conclusions: Despite the extensive decline in substance use during the pandemic period, these results suggest an association between previous mental health conditions and behavioral risk factors, leading to increased alcohol consumption and behavioral disorders manifestations.

Abstract Background: Pentalinon andrieuxii, is a medicinal plant used in Mayan folk medicine against leishmaniosis. It is an important source of terpenoids whose biosynthesis has been reported to be influenced by the ontogeny of the plant. Hypotheses: Flowering positively influences the production of urechitol A in Pentalinon andrieuxii. Studied species: Pentalinon andrieuxii (Müll. Arg.) B.F. Hansen & Wunderlin (Apocynaceae) Study site and dates: Mérida, Yucatán, Mexico, 2019 and 2020. Methods: Flowering was induced by exposing plants to temperatures above 32 °C. Plant tissue samples were collected before flowering induction and at full bloom and extracted with methanol. Analyses of the dichloromethane-soluble fraction of the crude extract by Gas Chromatography-Mass Spectrometry allowed the detection and quantification of urechitol A. Results: Flowering stage of P. andrieuxii has a positive influence on the production of urechitol A in the root of the plant, with the contents of the tri-nor-sesquiterpene increasing from a minimum of 43 to a maximum of 91 times during the flowering stage of plants, both transformed and wild type. Conclusions: P. andrieuxii perceives high temperatures as an important environmental cue to flower; flowering positively influences the production of urechitol A in the roots of the plant; production of the tri-nor-sesquiterpene is controlled by the plant.

Abstract Species of the genus Anastrepha cause injuries to several fruits and vegetables in the Nearctic and Neotropical regions. Among these species, many are present in Brazil. In this study, we surveyed the existing Anastrepha species in the Brazilian Chaco Biome. We evaluated possible influences of climate and vegetation on the occurrence of Anastrepha spp. For this, we used traps and hydrolyzed protein as bait. Collections were carried out in three distinct floristic compositions in the Chaco biome, from permanently dry areas to flooded sites. We identified Anastrepha fraterculus (Wiedemann, 1830), A. sororcula Zucchi 1979, A. undosa Stone 1942, and A. daciformis Bezzi 1909. The dry and flooded environment did not influence the occurrence of Anastrepha species. The presence of multiple hosts increases the number of species. The richness and abundance of Anastrepha species are lower in the Brazilian Chaco than in other native environments. regions Brazil study Biome spp bait biome sites Wiedemann, Wiedemann (Wiedemann 1830, 1830 , 1830) A 1979 1942 1909 environments 183 197 194 190 18 19 1

Resumo Relatos da medicina popular costumam atuar como referencial para o desenvolvimento de novos fármacos a partir de moléculas naturais com ações terapêuticas para doenças de alta gravidade e prevalência como o câncer. Bromelia antiacantha Bertol. é uma espécie da família Bromeliaceae, considerada uma planta alimentícia não convencional (PANC), encontrada nas regiões sul e centro-oeste do Brasil. Apesar do alto teor nutritivo e potencial farmacológico de seus frutos, poucos estudos científicos relatam suas ações biológicas. Desta forma, este estudo avalia o perfil fitoquímico de extratos aquoso e etanólico obtidos de frutos de B. antiacantha, bem como a sua possível ação antioxidante, antitumoral e citotóxica. O extrato aquoso apresentou compostos fenólicos e flavonoides, enquanto os extratos etanólicos apontam a presença de flavonóides e cumarina em sua composição, independente da região de coleta. O extrato etanólico demonstrou efeito antioxidante mais promissor do que o extrato aquoso e também induziu uma inibição significativa na viabilidade de células humanas de câncer cervical da linhagem SiHa. Além disso, o tratamento com ambos extratos não alterou a viabilidade de células não tumorais da linhagem de queratinócitos humanos imortalizados (HaCaT). Estes dados trazem novas informações sobre extratos obtidos de uma espécie vegetal nativa, comestível e já utilizada tradicionalmente, mas abrindo novas perspectivas quanto a possíveis aplicações terapêuticas.
Abstract Reports from popular medicine usually act as a basis for the development of new drugs from natural compounds with therapeutic actions for serious diseases and prevalence such as cancer. Bromelia antiacantha Bertol. is a species of the Bromeliaceae family, considered an unconventional food plant, found in the south and midwest regions of Brazil. Despite the high nutritional content and pharmacological potential of its fruits, few scientific studies report its biological actions. Thus, this study evaluates the phytochemical profile of aqueous and ethanol extracts obtained from B. antiacantha fruits, as well as their possible antioxidant, antitumor, and cytotoxic activities. The aqueous extract exhibited phenolic compounds and flavonoids, while ethanol extracts indicated the presence of flavonoids and coumarin in their composition, regardless of the region of collection. The ethanolic extract demonstrated a more promising antioxidant effect than the aqueous extract and also induced a significant inhibition in the viability of human cervical cancer cells of the SiHa strain. In addition, treatment with both extracts did not alter the viability of non-tumor cells of the immortalized human keratinocyte lineage (HaCaT). These results bring new data about extracts obtained from a native plant, edible and traditionally used in popular medicine, opening new perspectives for its possible therapeutic application.

Abstract In South America, Tambaqui (Colossoma macropomum) stands as the primary target for aquaculture, yet breeding programs for this Amazon native species are in their early stages. While high-density single nucleotide polymorphism (SNP) arrays are pivotal for aquaculture breeding, their costs can be prohibitive for non- or semi-industrial species. To overcome this, a cost-effective approach involves developing low-density SNP arrays followed by genotype imputation to higher densities. In this study, a 1K SNP array for tambaqui was created and validated, offering a balance between SNP quantity and genome representativity. The imputation accuracy from various SNP densities to a medium-density array was evaluated, with the 1K density demonstrating the best trade-off (accuracy of 0.93). This subset was further utilized to construct a commercial array through Agriseq™ targeted genotyping-by-sequencing, validated in 192 DNA samples, affirming its high quality for genotyping tambaqui. The low-density SNP array, with genome-wide coverage and high polymorphism, emerges as an effective tool for exploring genetic variation within diverse populations. Population analyses using the 1K panel proved to be an efficient tool for genetic characterization of sampled broodstocks, making it a valuable resource for genetic improvement programs targeting this Amazon native species.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Abstract The main objective of this study was to evaluate the biometric relationships between the species Bagre bagre, Lutjanus synagris and Nebris microps and their otoliths. The relationship between the size of the otolith (length and weight) and the size of the fish (standard length and total weight) was determined using the linear regression model (y = a + bx). For the morphological description, the otoliths of three specimens were selected by standard length class (10mm). The morphological characters analyzed were chosen according to traditional literature. Three hundred eight specimens of B. bagre, 200 of L. synagris and 237 of N. microps were analyzed. Throughout the collection period, the source of the capture of individuals was the municipality of Raposa. The linear correlations for fish and otolith length for B. bagre were 0.9129 and 0.9652, respectively. For L. synagris, the coefficients were 0.8634 and 0.8672, while for N. microps, 0.9597 and 0.8636, respectively. The morphological classification of L. synagris and N. microps is of the Saggita type, and the B. bagre species is of the Lapillus type. From the data presented here, it is possible to observe that otolith morphometric and morphological data can serve as a parameter to estimate the relationship between the fish and the otolith in terms of its biomass and the length of an individual and a population. weight y bx. bx . bx) description 10mm. 10mm mm (10mm) literature B 20 L 23 N period Raposa 09129 0 9129 0.912 09652 9652 0.9652 respectively 08634 8634 0.863 08672 8672 0.8672 09597 9597 0.959 08636 8636 0.8636 type here population (10mm 2 0912 912 0.91 0965 965 0.965 0863 863 0.86 0867 867 0.867 0959 959 0.95 091 91 0.9 096 96 0.96 086 86 0.8 095 95 09 9 0. 08 8

Abstract Background: Arboviral diseases are a group of infectious diseases caused by viruses transmitted by arthropods, mainly mosquitoes. These diseases, such as those caused by the dengue (DENV), Zika (ZIKV), chikungunya (CHIKV), and yellow fever (YFV) viruses, have a significant impact worldwide. In this context, entomological surveillance plays a crucial role in the control and prevention of arboviruses by providing essential information on the presence, distribution, and activity of vector mosquitoes. Based on entomological surveillance, transovarian transmission provides information regarding the maintenance and dissemination of arboviruses. The objective of this study was to detect these arboviruses in Goiânia, Goiás, and analyze the occurrence of transovarian transmission. Methods: Aedes aegypti eggs were collected from different regions of Goiânia and cultivated under controlled laboratory conditions until the emergence of adult mosquitoes. Adult females were grouped into pools containing their heads and thoraxes. These pools were subsequently evaluated using reverse-transcription quantitative polymerase chain reaction (RT-qPCR) assay. Results: A total of 157 pools (N=1570) were analyzed, with two pools testing positive for CHIKV and one pool testing positive for ZIKV, indicating that the offspring resulting from transovarian transmission are potentially infectious. Conclusions: In summary, the demonstration of the vertical transmission mechanisms of CHIKV and ZIKV in A. aegypti serves as an alert to health authorities, as these diseases are still underreported, and their primary urban vector has likely acquired this capacity, contributing to the dissemination of these infections.

Abstract Introduction : After the implementation of mitigation strategies during the COVID-19 pandemic, the incidence of respiratory viruses, including human coronaviruses (HCoV), experienced a significant decrease. The aim of this study is to characterize the epidemiology and clinical aspects of HCoV infections in ambulatory adults during COVID-19 pandemic times. Methods : descriptive, prospective, longitudinal study performed in a private hospital in La Plata, Buenos Aires, Argentina between November 2020 and October 2022; 458 outpatient adults with upper respiratory tract infections (URTI) were studied undergoing clinical and microbiological follow-up. Results : 44 (9.6%) subjects were positive by multiplex PCR for HCoV. 14 of them for 229E (31.8%), 13 for OC43 (29.5%), 11 for HKU-1 (25.1%) and 6 for NL63 (13.6%). A repeated PCR was positive for the same HCoV in 19 (57%) of 33 patients on day 3-5. No hospitalizations or deaths were reported. Discussion : Endemic HCoV caused a significant pro portion of URTI among outpatient adults during COVID- 19-related restrictions times. An alternating pattern of circulation between alfa-HCoV and beta-HCoV was observed.

Resumo Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae) causa perdas consideráveis às lavouras de soja no Brasil e em vários outros países da América do Sul. A aplicação de inseticidas biológicos pode ser uma alternativa eficaz para suprimir esta praga. O objetivo deste estudo foi avaliar a eficácia de inseticidas microbiológicos formulados a partir dos fungos Beauveria bassiana + Metarhizium anisopliae (Bometil) e B. bassiana (Ballvéria), e bactéria Bacillus thuringiensis (Acera) isoladamente e em combinação com os inseticidas químicos fipronil, etiprole e clorpirifós, contra adultos de M. armatus. Os inseticidas à base de B. bassiana + M. anisopliae foram mais patogênicos que os à base de B. bassiana, causando taxas de mortalidade acumuladas nos dez dias com 85,0 e 65,0% respectivamente. Em contraste, B. thuringiensis causou 92,5% de mortalidade. Estes produtos sozinhos e em combinação foram eficazes para o controlo nas suas concentrações mais baixas. Portanto, o uso de inseticidas microbiológicos individualmente ou em combinação com inseticidas químicos é uma alternativa promissora para o manejo integrado de M. armatus.

Abstract Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae) causes considerable losses to soybean crops in Brazil and several other South American countries. Applying biological insecticides can be an effective alternative to suppressing this pest. The objective of this study was to assess the efficacy of microbiological insecticides formulated from the fungi Beauveria bassiana + Metarhizium anisopliae (Bometil) and B. bassiana alone (Ballvéria), and the bacterium Bacillus thuringiensis (Acera) alone and in combination with the chemical insecticides fipronil, ethiprole and chlorpyrifos, against M. armatus adults. The insecticides based on B. bassiana + M. anisopliae were found to be more pathogenic than those based on B. bassiana, causing cumulative mortality rates in the ten days of 85.0 and 65.0% respectively. In contrast, B. thuringiensis caused 92.5% mortality. These products alone and in combination were effective for control at their lowest concentrations. Therefore, the use of microbiological insecticides individually or in combination with chemical insecticides is a promising alternative for the integrated management of M. armatus.

Resumo Atualmente, Myloplus schomburgkii representa a espécie mais facilmente reconhecida entre os serrasalmídeos, por apresentar uma barra preta vertical no meio do corpo. No entanto, através de uma ampla revisão taxonômica, incluindo DNA barcoding e análises morfológicas, conseguimos identificar e descrever duas novas espécies que também compartilham a barra vertical escura no flanco. Além disso, redescrevemos M. schomburgkii, designando um neótipo e restringindo a localidade-tipo ao rio Negro, Barcelos, Estado do Amazonas, Brasil. As três linhagens de pacus de barra preta apresentam altas divergências moleculares (7,9–11%) e podem ser morfologicamente distinguidas por diferenças na forma da barra vertical, forma da nadadeira anal nas fêmeas, número de vértebras totais, número de raios ramificados na nadadeira dorsal, entre outros caracteres. Embora a existência dessas duas novas espécies tenha sido ocultada devido a grandes semelhanças morfológicas, principalmente pela presença da barra vertical preta, as três linhagens não compõem um grupo monofilético, com uma das novas espécies sendo recuperada como irmã de Ossubtus xinguense.

Abstract Presently, Myloplus schomburgkii is the most easily recognized species among the serrasalmids by having a vertical black bar in the middle of the body. However, through a broad taxonomic review, including DNA barcoding and morphological analyses, we were able to identify and describe two new species that also share a dark vertical bar on the flank. In addition, we redescribe M. schomburgkii, designating a neotype and restricting the type-locality to rio Negro in Barcelos, Amazonas State, Brazil. The three lineages of black-barred pacus present high molecular divergences (7.9–11%) and can be distinguished by differences in the shape of the vertical bar, shape of females’ anal fin, number of total vertebrae, number of total branched dorsal-fin rays, among other characters. Although the existence of these two new species has been hidden due to many morphological similarities, mainly the presence of the black bar, the three lineages do not compose a monophyletic group, with one of the new species being recovered as sister to Ossubtus xinguense. This result reinforces the necessity of the redefinition of the Myleini genera.

SUMMARY Beckwith-Wiedemann syndrome (BWS) is a common genetic congenital disease characterized by somatic overgrowth and its broad clinical spectrum includes pre- and post-natal macrosomia, macroglossia, visceromegaly, increased risk of neonatal hypoglycemia, and development of embryonic tumors. BWS occurs due to genetic/epigenetic changes involving growth-regulating genes, located on region 11p15, with an important genotype-phenotype correlation. Congenital adrenal hyperplasia (CAH) comprises a spectrum of autosomal recessive diseases presenting a variety of clinical manifestations due to a deficiency in one of the enzymes involved in cortisol secretion. Early diagnosis based on newborn screening prevents the adrenal crisis and early infant death. However, high 17-hydroxyprogesterone (17-OHP) levels can occur in newborns or premature infants without CAH, in situations of stress due to maternal or neonatal factors. Here, we report new cases of false-positive diagnosis of 21-hydroxylase deficiency during newborn screening – two girls and one boy with BWS. Methylation-specific multiplex ligation-dependent probe amplification revealed a gain of methylation in the H19 differentially methylated region. Notably, all three cases showed a complete normalization of biochemical changes, highlighting the transient nature of these hormonal findings that imitate the classical form of CAH. This report sheds light on a new cause of false-positive 21-hydroxylase deficiency diagnosis during newborn screening: Beckwith-Wiedemann syndrome.

Abstract Despite the prevalence of substance use during pregnancy, studies focusing exclusively on Neonatal Intensive Care Units (NICU) admissions remain limited. This study investigates the impact of maternal use of tobacco, alcohol, and/or crack, on neonatal outcomes among infants admitted to three Brazilian NICUs. Additionally, the investigation explores the impact of substance use on DNA damage in newborns. Over a one-year period, data from 254 newborns were collected through medical records, accompanied by blood samples. Findings revealed that 16.1% of newborns had mothers reporting substance use during pregnancy. Significant associations were found between maternal substance use and adverse neonatal outcomes, including low birth weight, preterm birth, and sexually transmitted infections. Maternal variables linked to substance use encompassed non-white skin color, low education, non-masonry housing, lower income, diseases in other children, and fewer prenatal consultations. Notably, neonatal DNA damage showed no significant association with substance use. Our results underscore the substantial impact of maternal substance use on NICU-admitted infants, emphasizing the necessity for targeted interventions that address both neonatal health and maternal well-being, thereby underscoring the crucial role of comprehensive care in NICU settings. pregnancy (NICU limited tobacco alcohol andor or crack NICUs Additionally oneyear one year period 25 records samples 161 16 1 16.1 weight infections nonwhite non white color education nonmasonry masonry housing income children consultations Notably NICUadmitted wellbeing, wellbeing well being, being well-being settings 2 16.

Abstract Background Depression and anxiety are two of the most prevalent and disabling mental disorders worldwide, both in the general population and in outpatient clinical settings. Objective This study aimed to analyze the psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) based on network analysis metrics. Methods A total of 911 Paraguayans (23.71% women and 76.29% men; mean age 31.25 years, SD = 10.63), selected by non-probabilistic convenience sampling, participated in the study. Network analysis was used to evaluate the internal structure, reliability, and measurement invariance between men and women. Results The results revealed that the PHQ-4 is a unidimensional measure through Exploratory Graph Analysis (EGA). Reliability, through structural consistency, identified that 100% of the time, only a single dimension was obtained, and all items remained stable, as they were always replicated within the empirical dimension. The unidimensional structure has shown evidence of configural invariance; therefore, the network structure functioned equally among the different sex groups. Conclusion The PHQ-4 presented optimal preliminary evidence of validity based on its internal structure, reliability, and invariance between sexes. Therefore, it may be useful as an accurate and brief measure of anxiety and depressive symptoms in the Paraguayan context. worldwide settings Questionnaire4 Questionnaire 4 Questionnaire- PHQ4 PHQ (PHQ-4 metrics 91 23.71% 2371 23 71 (23.71 7629 76 29 76.29 3125 31 25 31.2 years 10.63, 1063 10.63 , 10 63 10.63) nonprobabilistic non probabilistic sampling reliability PHQ- EGA.

Nanoparticles of zein (NPZ) stabilized with surfactant polyvinyl alcohol (PVA), and nanoparticles of zein/PVA loaded with eugenol (NPZ-Eug) and the essential oil extracted from the clove (Syzygium aromaticum) (NPZ-OC) were produced by nanoprecipitation method. The extraction method of essential oil of the clove was carried out by the hydrodistillation technique, obtaining a content of 81.5% (m/m) of eugenol. The nanoparticle preparation method was optimized using a one-factor-at-a-time design of experiments, where different levels of variables (zein concentration, PVA concentration, and eugenol concentration) were explored. The best condition of synthesis was obtained with 0.3% (m/v) zein, 0.6% (m/v) PVA and 1.5 mg L-1 eugenol or essential oil of the clove, reaching NPs with acceptable propriety for stable nanoparticulate systems: size particles (NPZ = 113, NPZ-Eug = 229 and NPZ-OC = 279 nm), polydispersity index (PDI < 0.26), and zeta potential (≈ -30 mV). Loaded NPs showed encapsulation efficiency and drug-loading of 52 and 20% (NPZ-Eug), and 62, 27% (NPZ-OC), respectively. The quantification method of eugenol was validated by analytical parameters. Finally, all NPs produced exhibited good colloidal stability, confirming the effectiveness of PVA as a stabilizing agent, which had not been previously reported for these systems. The results obtained provide promising prospects for further investigations into its potential application as a bioinsecticide agent.
