A new alkaloid, named brazoide Ε (6), three known steroids (campesterol, β-sitosterol, stigmasterol), two glucosides (3-O-β-D-glucopyranosylsitosterol and 3-O-β-D-glucopyranosyl stigmasterol) and sucrose were isolated from the leaves and stems of Justicia wasshauseniana. Their structures were characterized using high-resolution electrospray ionization mass spectrometry (HRESIMS), nuclear magnetic resonance (1D and 2D NMR), and infrared (IR) spectroscopy. To reinforce the structural proposal, an acetylated derivative (6a) was obtained and its data compared to 6. Moreover, circular dichroism spectroscopy (CD) analysis was performed to determine the absolute stereochemistry, time-dependent density functional theory (TD-DFT) at the wB97X-D/def2-TZVP level, adopting functionals M06-2X and wB97X-D and base aug-cc-pVDZ, was employed to confirm the CD analysis. alkaloid 6, 6 , (6) campesterol, campesterol (campesterol βsitosterol, βsitosterol β sitosterol, sitosterol β-sitosterol stigmasterol, stigmasterol 3OβDglucopyranosylsitosterol OβDglucopyranosylsitosterol 3 O D glucopyranosylsitosterol 3OβDglucopyranosyl OβDglucopyranosyl glucopyranosyl wasshauseniana highresolution high resolution HRESIMS, HRESIMS (HRESIMS) 1D NMR, NMR NMR) IR (IR proposal 6a a (6a Moreover (CD stereochemistry timedependent time dependent TDDFT TD DFT (TD-DFT wB97XD/def2TZVP wB97XDdef2TZVP wBXDdefTZVP wB97X D/def2 TZVP def2 wB X def level M062X MX M06 2X M wB97XD wBXD augccpVDZ, augccpVDZ aug cc pVDZ, pVDZ aug-cc-pVDZ (6 (HRESIMS def2TZVP XD XDdef wBX Ddef2 Ddef D/def M0 ( defTZVP

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 aim of this study was to assess how microclimate variables and irrigation affect the growth of sugarcane. The experiment was conducted using the VAT90-212 cultivar in the Semi-arid region of Brazil. The microclimate was monitored and by quantifying the irrigation depth. Nine campaigns were carried out in the field to collect morphological and biomass data. The data were subjected to descriptive statistics, so as to generate the mean values and/or sum between the campaigns. Using the correlation coefficient, the extent, sign and significance of the relationship between the response and explanatory variables were evaluated. The direct or indirect effects of the explanatory variables on the response variables were identified by path analysis. There was a significant correlation between microclimate variables and the morphological and biomass variables of the sugarcane, with a strong contribution from the intercepted fraction of the photosynthetically active radiation, the wind speed and soil temperature. The negative correlation with irrigation suggests that excess water impaired the growth dynamics of the crop. It is concluded that the growth of sugarcane is closely related to its capacity to intercept radiation, to the wind, thermal regime of the soil and irrigation management.

ABSTRACT The study aimed to determine the evapotranspiration (ETc) of the mango cv. ‘Palmer’ over two productive cycles, analyzing water-use efficiency (WUE) and crop water productivity (CWP) to propose average crop coefficient (Kc) values for improving irrigation management under cultivation conditions in the Low-Middle São Francisco Valley. The study was conducted from July 2019 to May 2021 in a commercial ‘Palmer’ mango orchard in Petrolina, State of Pernambuco, Brazil. Micrometeorological data was collected throughout the experimental period. The crop evapotranspiration (ETc) was determined using Bowen ratio energy balance (BREB), and then the Kc, WUE, and CWP were determined. The highest ETc values occurred during the floral induction phase (5.14 ± 0.85 mm day-1), with a Kc of 0.85; however, the lowest values were observed during the fruit maturation phase (3.60 ± 0.73 mm day-1), with a Kc of 0.91. Average water consumption per cycle was 1445 mm, with a daily average of 4.39 mm day-1. WUE and CWP were 16.9 and 24.5 kg ha-1 mm-1, respectively. Average Kc values of 0.81, 0.76, 0.85, 0.90, 0.95, and 0.91 are recommended for the vegetative growth, rest period and shoot maturation, floral induction, flowering, fruit development, and fruit maturation phases, respectively.

Abstract Phytochemical studies of Cespedesia spathulata (Ochnaceae) leaves using 1H, 13C NMR, and GC-MS have led to the isolation of some metabolites identified for the first time in these species such as cathechin, epicatechin, vitexin, orientin, 6’’-O-acetyl-vitexin, sitosterol, stigmasterol, phytol, 4,5-dihydrovomifoliol and a mixture of aliphatic methyl esters, together with ochnaflavone, which was previously isolated from this plant. The modulating activity of some fractions and compounds from Cespedesia spathulata towards tyrosinase enzyme was assayed by spectroscopic and theoretical means/experiments. The dichloromethane fraction (133 μg mL-1) and ochnaflavone (333 μM) inhibited tyrosinase activity by 20 % and 2.0 %, respectively, whereas the ethyl acetate fraction (666 μg mL-1) and ±catechins (catechin and epicatechin - 800 μM) activated it by 104 % and 384 %, respectively. Quantum chemical calculations suggested that catechin and epicatechin are better activators than L-DOPA by interacting with Cu (II) ions. Molecular docking results suggested that hydrogen bonding and hydrophobic interactions are the main binding forces between each tyrosinase activator and the amino acid residues inside the active protein binding pocket.

Abstract: This study aims to identify phenolic compounds in dichloromethane and methanolic extracts of the rhizome of Renealmia nicolaioides collected in the North Region of Brazil. Two known diarylheptanoids, 1,7-bis(4-hydroxyphenyl)-(1E)-1-hepten-3-one (1), and 5R-1,7-bis(4-hydroxyphenyl)-1E-hepten-5-ol (2), and a new one (1R,2S,5S)-2-hydroxy-1,7(p-hydroxyphenyl)-centrolobine (3), as well as one flavonoid, 3-metoxi-quercetin (4) were isolated by chromatographic procedure and identified by spectroscopic techniques (1H and13C NMR, HRMS and CD). The acetyl derivative of 2 was used to confirm its structure. All four compounds are reported for the first time for this genus, and this is the first occurrence of compound 1 as a natural metabolite. The results reported here are unprecedented for the genus Renealmia.

The secondary metabolites of the aerial parts of Phyllanthus acuminatus Vahl (Phyllanthaceae) and the biological activity of one of them were characterized in this study. This chemical investigation led to isolation of two lignans, luclaricin (1), a new arylnaphtalene-typelignan, and justicidin B (2). The structures of isolated compounds were determined based on 1D and 2D-NMR, HRESIMS and IR. The cytotoxic activity of justicidin B was assessed against tumor cell lines (MCF-7, U251, NCI-ADR/RES, NCI-H460, OVCAR-3, HT29 and K562) and a non-tumor cell line (HaCat) using sulforhodamine B assay. Justicidin B showed strong cytotoxic activity against the tumor cell lines HT29, K562 and U251 with GI50 values of 2.28, 3.29 and 5.76 mol L-1, respectively.

ABSTRACT The Pantanal is the largest inland wetland in the world and is under increasing anthropogenic threats, including long-term regionally intensive gold mining practices. Gold mining activities are known to cause the release of harmful pollutants such as mercury (Hg) to the surrounding environment. Jaguars (Panthera onca (Linnaeus, 1758)) are apex predators, and therefore show great potential to accumulate Hg by biomagnification. We hypothesize that total Hg content in the fur of jaguars from two sites within the Brazilian Pantanal would be significantly different as a function of distance from active gold mining operations. The Hg content was determined by fluorescence spectrometry. The mean ± SD Hg content in jaguars from the study site influenced by gold mining (SB) was compared to jaguars sampled in the area free of gold mining activities (CA) using a one-way ANOVA. The mean Hg content in jaguars from SB (673.0 ± 916.8 µg g-1) is significantly different from jaguars sampled in CA (29.7 ± 23.3 µg g-1), p = 0.03. The maximum recorded content of Hg was 2,010.4 ± 150.5 µg g-1, highest level ever recorded in a wild animal. The data indicate that Hg is an important threat to jaguars within at-risk regions of the Pantanal.

Beauveria bassiana is an entomopathogenic fungus that has been well known for its capacity to act as biopesticide on various disease vectors. The analysis of organic extracts of strains CG71 and UNI40 led to identification of cyclodepsipeptides beauvericin, beauvericin A or F, beauvericin E and bassianolide by ultra-high pressure liquid chromatography-high resolution mass spectrometry in tandem mode (UHPLC-HRMS/MS). The larvicidal activity on 3rd instar of Aedes aegypti revealed LC50 0.9887 and 0.4653 ppm in 24 and 48 hours (CG71 methanolic extract), LC50 0.7834 ppm in 48 hours (CG71 ethyl acetate), LC50 0.7834 and 1.8149 ppm (UNI 40 for ethyl acetate and methanolic extracts, respectively) in 48 hours. These findings highlight the potential of B. bassiana metabolites for controlling the vector of Dengue and Zika diseases.

ABSTRACT This study aims to identify special metabolites in polar extracts from Urochloa humidicola (synonym Brachiaria humidicola) that have allelopathic effects and induce secondary photosensitization in ruminants. The compounds were isolated and identified via chromatographic and spectroscopic techniques. The compounds 4-hydroxy-3-methoxy-benzoic acid, trans-4-hydroxycinnamic acid, and p-hydroxy-benzoic acid; the flavonols isorhamnetin-3-O-β-d-glucopyranoside and methyl quercetin-3-O-β-d-glucuronate; and kaempferitrin, quercetin-3-O-α-l-rhamnopyranoside, and tricin were identified in the extract from the leaves of Urochloa humidicola. Two furostanic saponins, namely, dioscin and 3-O-α-l-rhamnopyranosyl-(1-4)-[α-l-rhamnopyranosyl-(1-2)]-β-d-glucopyranosyl-penogenin, as well as catechin-7-O-β-d-glucopyranoside were identified in the methanolic extract obtained from the roots of this plant. This species features a range of metabolites that may be toxic for animals if used in food and may interfere with the growth medium, thereby inhibiting the development of other species.

The phytochemical investigation of Clusia lanceolata leaves yielded fourteen compounds including six flavones, vitexin, isovitexin, isovitexin-2"-O-α-L-rhamnopyranoside, vitexin-2"-O-α-L-rhamnopyranoside, orientin and isoorientin, two phaeophytins [132-hydroxy-(132-S-)-phaeophytin a and 132-hydroxy-(132-R)-phaeophytin a], two triterpenes, α- and β-amyrin, and four steroids, β-sitosterol, stigmasterol, sitosterone and stigmasterone. Their structures were assigned based on spectroscopic analysis, including two-dimensional NMR techniques and comparison with literature data. The antioxidant capacity in vivo of vitexin and mixing isovitexin-2"-O-α-L-rhamnopyranoside and vitexin-2"-O-α-L-rhamnopyranoside was evaluated using the yeast Saccharomyces cerevisiae as the biological system model and hydrogen peroxide as a stressor agent. The results showed that the tested flavonoids were able to protect the yeast cell against the oxidative damage caused by H2O2.

Abstract The aim of the current study is to evaluate the effect of Acmella oleracea (L.) R.K. Jansen, Asteraceae, methanolic extract, hexane (84.28% spilanthol) and dichloromethane (approximately 100% spilanthol) fractions on the tyrosinase enzyme. The dehydrated jambu extract was obtained through maceration using methanol. The extract residue was solubilized in MeOH/H2O (8:2) and subjected to liq.–liq. partition in organic solvents. Both the extraction and the partition procedures were conducted with three replicates. The analyses were performed using GC–MS, 1H and 13C NMR. The hexane fraction provided samples containing 84.28, 82.91 and 62.83% spilanthol in repetitions 1, 2 and 3, respectively. The dichloromethane fraction showed 88.55% spilanthol in repetition 1, and approximately 100% spilanthol in repetitions 2 and 3. The jambu extract as well as the hexane fraction (84.28% spilanthol) were able to activate the oxidizing activity of the tyrosinase enzyme for L-DOPA. The dichloromethane fraction (approximately 100% spilanthol) showed stronger inhibition effect on the tyrosinase enzyme in the first 10 min. The results raise the interest in study in spilanthol formulations for topical use, since it may prevent and/or slow skin hyperpigmentation or depigmentation processes. Furthermore, spilanthol may be used to control the enzymatic browning in fruits and vegetables.

Abstract Spilanthol (C14H23NO, 221.339 g/mol) is a bioactive compound that is found in many different plants that are used as traditional remedies throughout the world. It is present in Heliopsis longipes and several species in the genus Acmella, including A. oleracea L., also known as paracress and jambu. Its leaves and flowers have sensory properties (pungency, tingling, numbing, mouth-watering) that make it a popular spice and ingredient in several Brazilian dishes. Spilanthol can exert a variety of biological and pharmacological effects including analgesic, neuroprotective, antioxidant, antimutagenic, anti-cancer, anti-inflammatory, antimicrobial, antilarvicidal and insecticidal activities. So, the aim of this review is to present a literature review on the spilanthol that describes its occurrence, chemistry, extraction and biological activities.

A reflexão sobre o mercado é um tema caro ao substantivismo polanyiano. Em seu modelo da economia antiga, Karl Polanyi defendeu a preponderância da reciprocidade e redistribuição em detrimento do mercado autorregulável no mundo antigo. Os assiriólogos, sejam os defensores fervorosos do modelo polanyiano, como Johannes Renger, ou os críticos ferozes a tal modelo, como Morris Silver, têm debatido o papel do mercado no antigo Oriente próximo em meio a outras interpretações que procuram reinterpretar as mais diversas fontes textuais e arqueológicas da sociedade mesopotâmia em diversos períodos, como, por exemplo, o trabalho de Mario Liverani. Ao analisar os argumentos desses autores pa radigmáticos, pretende-se, neste artigo, por meio da apresentação e repercussão do modelo polanyiano, apresentar um amplo painel crítico do debate sobre a economia e a sociedade na Mesopotâmia.
The reflection on the market is a fundamental topic of substantivism. In his model of the ancient economy, Karl Polanyi defended the preponderance of reciprocity and redistribution at the expense of self-regulating market in the ancient world. Assyriologists, be they fervent defenders of the Polanyian model, as Johannes Renger, or fierce critics of such model, as Morris Silver, have discussed the role of the market in the ancient near East along with other interpretations that seek to reassess the several archaeological and textual sources of the Mesopotamian society in various periods as in the work of Mario Liverani. By analyzing the arguments of these paradigmatic authors in this paper, I intend to propose an ample critical view of the discussion on the economy and society in Mesopotamia.

<p>Em meados da década de 1980, os ditos supercondutores cerâmicos foram descobertos. Estes materiais se destacam por possuírem temperaturas de transição superiores à do nitrogênio líquido (<italic>T</italic> = 77 K). Este líquido criogênico possui um custo e facilidade de obtenção muito mais vantajosos se comparado com o hélio líquido (<italic>T</italic> = 4, 2 K). Assim, as possibilidades de aplicações desses materiais se ampliaram. Tais aplicações se adequam, em geral, aos esforços por buscas de fontes de energia limpas e a estruturação de uma sociedade sustentável por conta das propriedades dos supercondutores (por exemplo, resistividade nula e diamagnetismo perfeito). Neste trabalho apresentaremos a montagem de um experimento de levitação supercondutora que pode ser usado em problematizações a alunos do ensino médio além de incentivá-los a optarem por uma carreira científica.</p>
<p>In the middle of 1980’s, the ceramic superconductors were novel materials that exhibit superconductivity at temperatures larger than that of liquid nitrogen (<italic>T</italic> = 77 K). This cryogenic liquid is easier to be obtained and cheaper than liquid helium (<italic>T</italic> = 4.2 K). Thus, the possibility of applications of such materials increased and they are suited to the efforts to search clean energy sources and the growth of a sustainability society. This is possible due to the properties of the superconductors as zero resistivity and perfect diamagnetism. In this work we will present the arrangement of a superconducting levitation experiment that can be used as a motivation for high school students and also to encourage them to choose a scientific career.</p>
