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 Long-term-ecological-research (LTER) faces many challenges, including the difficulty of obtaining long-term funding, changes in research questions and sampling designs, keeping researchers collecting standardized data for many years, impediments to interactions with local people, and the difficulty of integrating the needs of local decision makers with “big science”. These issues result in a lack of universally accepted guidelines as to how research should be done and integrated among LTER sites. Here we discuss how the RAPELD (standardized field infrastructure system), can help deal with these issues as a complementary technique in LTER studies, allowing comparisons across landscapes and ecosystems and reducing sampling costs. RAPELD uses local surveys to understand broad spatial and temporal patterns while enhancing decision-making and training of researchers, local indigenous groups and traditional communities. Sampling of ecological data can be carried out by different researchers through standardized protocols, resulting in spatial data that can be used to answer temporal questions, and allow new questions to be investigated. Results can also be integrated into existing biodiversity networks. Integrated systems are the most efficient way to save resources, maximize results, and accumulate information that can be used in the face of the unknown unknowns upon which our future depends.

Abstract The oceans play an important role in mitigating climate change by acting as large carbon sinks, especially at high latitude regions. The Southern Ocean plays a major role in the global carbon dioxide (CO2) budget. This work aims to investigate the behavior of turbulent CO2 fluxes and quantify it under different atmospheric and oceanic conditions in the Drake Passage and Bransfield Strait regions on high spatiotemporal resolutions when compared with traditional CO2 fluxes estimations. The atmospheric stability condition was used to corroborate the description of CO2 fluxes. In situ, satellite, and reanalysis data from 08 to 22 November 2018, were used in this work. The Bransfield Strait uptaked 38.59% more CO2 than the Drake Passage due to the cold and fresh waters, allied to the influence of glacial meltwater dilution. Which increased the CO2 solubility, directing the CO2 fluxes to the ocean. The Bransfield Strait had predominantly stable atmospheric conditions, which contributed to this region acting as a CO2 sink. The Drake Passage, on average, behaved as a CO2 sink, mainly due to physical characteristics. This research contributes to a better understanding of the Southern Ocean’s role in the global carbon balance on scales that are very difficult to monitor.

Abstract Storage is important in the coffee post-harvest. Determining the maximum period that coffee can remain storaged is important aiming to reduce losses in quality and, consequently, allow the producer to achieve maximum profitability. The aim was to determine the suitable storage period for natural and fully washed coffees, under different conditions. Beans were dried to 11% moisture content after dry processing (natural coffee, dry cherry coffee) and wet processing (parchment coffee, fully washed). Before storage, part of the coffee was hulled and part was not. The coffee was stored under refrigerated air (10ºC and 50% relative humidity) or in an environment at 25ºC. In the periods of 0, 3, 6, and 12 months, samples were taken for sensory, electrical conductivity and tetrazolium evaluation. Refrigerated environment favors conservation of sensory and physiological quality of the natural hulled coffee beans and fully washed coffee. Hulled beans of natural and fully washed coffee stored under refrigerated conditions have the initial quality conserved for up to 12 months and in non-controlled environmental, for up to 3 months. Mechanical damage caused by hulling, associated with the lack of tissue fruit parts, contributes to reduction hulled coffee quality in storage, regardless of the processing.

Resumo Objetivo O objetivo do presente estudo foi comparar prospectivamente os retalhos sural e propeller para cobertura de partes moles da extremidade inferior. Foram avaliadas as seguintes variáveis: incidência de perda total ou parcial do retalho e morbidade da área doadora (fechamento primário versus enxerto de pele). Métodos Análise prospectiva e randomizada de dados coletados de todos os pacientes apresentando defeitos em tecidos moles da extremidade distal da perna e do retropé submetidos aos retalhos em questão. Resultados Foram avaliados 24 pacientes com idades entre 4 e 60 anos, entre 2011 e 2017. Cobertura completa foi obtida em 22 dos 24 pacientes (91,6%) e observamos falha em 2 retalhos (8,4%). O retalho sural, sendo a opção mais popular, continua a representar uma alternativa segura e versátil para defeitos cutâneos do terço distal da perna e da região do calcanhar. O retalho propeller, da mesma maneira, mostrou-se uma opção comparável para o tratamento destas lesões desafiadoras. Conclusão Os retalhos sural e propeller são boas opções para a cobertura de partes moles da extremidade inferior, demostrando baixas taxas de complicações como perda parcial ou total do retalho.
Abstract Objective The objective of the present study was to prospectively compare the sural and propeller flaps for soft-tissues coverage of the lower extremity. The following variables were evaluated: incidence of complete or partial flap loss and donor area morbidity (primary closure versus skin graft). Methods Prospective and randomized analysis of data collected from all patients presenting with soft tissue defects of the lower third of the leg and heel treated with reverse sural or propeller flaps. Results Twenty-four patients aged between 4 and 60 years old were evaluated between 2011 and 2017. Complete coverage was obtained in 22 of the 24 patients (91.6%). Two flaps failed (8.4%). The sural flap, being the most popular option, continues to represent a safe and versatile alternative for skin defects of the lower third of the leg and heel region. Likewise, the propeller flap was a comparable option to treat these challenging defects. Conclusion Sural and propeller flaps are good options for soft tissues coverage of the lower extremity, with low complication rates (partial or total flap loss).

Abstract This paper documents an increase in the number of observed explosive cyclones (EC) at King George Island, South Shetland Islands, Antarctica, over the 1989‒2020 period. In ECs at 60o latitudes the surface atmospheric pressure drops ≥24 hPA in 24 hours. The annual EC frequency time series shows a significant positive trend of ~2.7 cyclones/decade, with a break in 2003 and average numbers of 7.3 and 11.8 events before and after that break, respectively. The increase follows closely earlier documented global sea surface temperature (SST) anomaly trends for the 1981‒2018 period, partially attributed to global warming and to the Pacific Decadal Oscillation (PDO). Connections between EC frequency and SST might occur through variations in SST in the southeastern Pacific and southwestern Atlantic, with anomalous cold conditions favoring an increase in ECs. We also found close relations between the number of ECs with simultaneous occurrences of PDO and Atlantic multidecadal oscillation in opposite phases, so that after 2003 they were in the cold and warm phases, respectively, and vice-versa before 2003. Both low-frequency modes seem to modulate the number of ECs. As per the authors knowledge these results have not been discussed before and may help climate modeling studies and weather forecasts.

Abstract The Antarctic region has experienced recent climate and environmental variations due to climate change, such as ice sheets and ice shelves loss, and changes in the production, extension, and thickness of sea-ice. These processes mainly affect the freshwater supply to the Southern Ocean and its water masses formation and export, being crucial to changes in the global climate. Here, we review the influence of the glacial freshwater input on the Antarctic Peninsula adjacent ocean. We highlight each climate process’ relevance on freshwater contribution to the sea and present a current overview of how these processes are being addressed and studied. The increase of freshwater input into the ocean carries several implications on climate, regionally and globally. Due to glacier melting, the intrusion of colder and lighter water into the ocean increases the stratification of the water column, influencing the sea-ice increase and reducing ocean-atmosphere exchanges, affecting the global water cycle. This study shows the role of each hydrological cycle processes and their contributions to the regional oceanography and potentially to climate.

ABSTRACT The presence of ants in apiaries has long been considered a problem for beekeeping. The health of the hives is a key issue in beekeeping since honey bees are affected by viruses, bacteria, fungi and parasites. Penicillium, Aspergillus and Fusarium are mycotoxigenic fungi, which are widely distributed throughout the world. The presence of these fungi has been observed in both the digestive tract of bees and honey. One of the most studied bacteria as antagonists is Bacillus. The objective of the study was to determine the antifungal activity of Bacillus subtilis against Aspergillus section nigri and Fusarium solani. The isolation was carried out in nutritive agar of B. subtilis from cuticles of ants from apiaries of the temperate valleys of the province of Jujuy, Argentina. The fungal strains were obtained from the strain collection of the Laboratory of Agricultural Microbiology and Beekeeping/ Stingless beekeeping Health of the Faculty of Agrarian Sciences, UNJu. The antagonism tests were performed on plates with potato dextrose agar medium with explants of the fungi against Bacillus subtilis incubated at 28 ° C for one week. Colony diameters were recorded, and the percentage of growth inhibition was determined at 5, 10 and 15 days. The inhibition percentages were higher after 5 days of incubation. The inhibition percentage was greater than 50% in Aspergillus section nigri and greater than 65% in Fusarium solani. Bacillus subtilis showed antifungal activity against the pathogenic fungi of bees under study.
RESUMEN La presencia de hormigas en los apiarios ha sido considerada durante mucho tiempo un problema para la apicultura. En la producción apícola es muy importante el aspecto sanitario de las colmenas, ya que las abejas melíferas son afectadas por virus, bacterias, hongos y parásitos. Penicillium, Aspergillus y Fusarium son micotoxigénicos con una amplia distribución en el mundo. Se ha demostrado la presencia de estos hongos en el tubo digestivo de las abejas y en la miel. Una de las bacterias más estudiadas como antagonistas es Bacillus. El objetivo del estudio fue determinar la actividad antifúngica de Bacillus subtilis frente Aspergillus sección nigri y Fusarium solani. Se realizó el aislamiento en Agar nutritivo de B. subtilis de cutículas de hormigas de colmenares de los valles templados de la provincia de Jujuy, Argentina. Los hongos fueron provistos por el cepario del Laboratorio de Microbiología Agrícola y Sanidad Apícola y Meliponícola de la Facultad de Ciencias Agrarias, UNJu. Las pruebas de antagonismo se realizaron en placas con medio agar papa dextrosa con explantes de los hongos frente a Bacillus subtilis incubadas a 28°C durante una semana. Se registraron los diámetros de las colonias y se determinó el porcentaje de inhibición a los 5, 10 y 15 días. Los porcentajes de inhibición fueron mayores a los 5 días de incubación. El porcentaje de inhibición fue mayor al 50% en Aspergillus sección nigri y mayor al 65% en Fusarium solani. Bacillus subtilis mostró actividad antifúngica contra los hongos patógenos de abejas en estudio.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Abstract This study aimed to optimize ultrasound-assisted palm oil-in-water nanoemulsions. The influence of hydrophilic-lipophilic balance (HLB), oil and surfactants concentrations, ultrasound intensity and processing time were investigated by means of two experimental designs. Desirability profiles were applied to detect the optimal conditions for preparing the nanoemulsion. Stable nanoemulsions with small droplet size and polydispersity index (PDI) were obtained at an HLB of 6.5, oil and surfactant concentrations of 2.8 wt%, ultrasound intensity of 200 W.cm-2 and processing time of 15 minutes. The nanoemulsion presented stability for 30 days at three different temperatures (4°C, 25°C and 40°C), which makes it suitable for application in the food and cosmetic industries. Ultrasound was shown to be a promising technology to produce nanoemulsions containing palm oil.

ABSTRACT The contamination of aquatic environments with chemical trace elements can be evaluated by their accumulation in sediments of the water body. Studies on mercury require the use of exclusive extraction techniques that have relatively high costs when compared to the analysis of other trace elements. This study was conducted aiming at determining the mercury concentration in sediments of the Upper Parnaíba River basin, located in a region of agricultural expansion between the states of Piauí and Maranhão. The sediment was collected at 12 sites in the basin. After drying, the quantification of total mercury was performed by the Zeeman atomic absorption spectrometry coupled to a pyrolysis reactor. Mercury concentrations in sediments of the Parnaíba River ranged from 4.2 to 58.5 ng g−1 and presented a low probability of adverse effects on biota. Mercury had no correlation with the variables clay, silt, sand, total organic carbon, iron, and aluminum, demonstrating its possible anthropogenic origin. Although mercury concentrations have a low probability to disturb the balance of the local ecosystem, there is a need for monitoring the region in order to quantify the risks to biota and human health.

La enfermedad de Pompe (EP) es un desorden metabólico autosómico recesivo infrecuente, producido por la ausencia o deficiencia de la enzima lisosomal alfa-glucosidasa ácida en los tejidos de los individuos afectados. Se considera enfermedad de Pompe de inicio tardío (EPIT) en aquellos individuos de más de un año de edad al comienzo de los síntomas. El objetivo del presente consenso es el de actualizar las pautas y recomendaciones para un correcto tratamiento de los pacientes con EPIT, tomando como referencia los lineamientos del Consenso Argentino para el diagnóstico, seguimiento y tratamiento de la enfermedad de Pompe publicado en el año 2013. Se organizó un consenso que reunió profesionales con experiencia en la EP en las áreas de clínica médica, diagnóstico de laboratorio, neuropatología, neumonología, nutrición, neurología, enfermedades metabólicas, enfermedades neuromusculares y rehabilitación. Se realizó una actualización de la bibliografía sobre EPIT, con especial atención en las publicaciones relevantes de los últimos cuatro años. Los términos finales del documento fueron consensuados por todo el grupo de trabajo. Cada participante proporcionó su declaración de conflicto de intereses. El resultado es una actualización del último Consenso Argentino para la EP, con particular enfoque en su forma de comienzo tardío. Tratándose de una afección infrecuente, en la que los datos disponibles son limitados, las presentes recomendaciones deben ser consideradas como opinión de expertos.
Pompe’s disease (PD) is an infrequent metabolic autosomic recessive disorder produced by the lack or deficiency of the acid alpha-glucosidase lysosomal enzyme in tissues of involved individuals. Delayed-onset PD is considered whenever symptoms onset start after one year of age. We present an update of the recommendations for the management of delayed-onset PD, taking as reference the guidelines from the Argentine Consensus for diagnosis, treatment and follow-up of PD published in 2013. The present consensus gathered several experts in PD in the areas of internal medicine, laboratory diagnosis, neuropathology, pulmonology, nutrition, neurology, metabolic and neuromuscular disorders as well as rehabilitation to perform an update of the literature of delayed-onset PD, with special attention on relevant information published within the last 4 years. The entire working group approved the final version of the consensus. Each participant provided a declaration of conflict of interest. As a result, it is an update of the previous Argentine PD Consensus with focus on the delayed-onset presentation of the disease. Being such infrequent disorder, available data were rather limited and thus, the recommendations represent expert opinions.

Desde 2003, en los países desarrollados han aumentado las comunicaciones sobre casos de linfogranuloma venéreo con cuadros clínicos diferentes de la forma inguinal clásica. Las presentaciones anorrectales, hasta hace poco atípicas, predominan en hombres infectados por HIV que tienen sexo con hombres. El objetivo de este trabajo es informar sobre la presencia de esta infección en la Ciudad Autónoma de Buenos Aires y describir sus variadas manifestaciones clínicas. En el contexto de una pesquisa sistemática de la infección rectal por clamidias, en apenas un trimestre fueron identificados ocho casos de linfogranuloma venéreo por Chlamydia trachomatis biovar LGV en hombres HIV positivos que tienen sexo con hombres. Las manifestaciones anorrectales más frecuentes fueron pujo, tenesmo, urgencia evacuatoria y secreción mucosa o hemopurulenta. En su mayoría presentaban proctitis leve o moderada, acompañada en algunos casos de lesiones perianales. Dados el polimorfismo y la inespecificidad de las manifestaciones clínicas del linfogranuloma venéreo rectal, se advierte sobre la circulación de esta infección en nuestro medio. En caso de detectar Chlamydia trachomatis, es importante genotipificarla para el correcto diagnóstico y tratamiento de la enfermedad y también para su vigilancia epidemiológica. Si la genotipificación no es posible, se debe considerar el caso como producido por el biovar LGV y aplicar el tratamiento correspondiente.
From 2003 to date there has been a rising number of reports from developed countries on cases of lymphogranuloma venereum with anorectal localization in HIV-infected men who have sex with men. This localization differs from the classical inguinal abscesses which are typical of the disease in the tropics. The objective of this work is to document the presence of anorectal lymphogranuloma venereum in Buenos Aires and to describe its varied clinical manifestations. In the context of a systematic survey of rectal chlamydial infection, in just one trimester, eight cases of lymphogranuloma venereum caused by Chlamydia trachomatis biovar LGV were identified in HIV-infected men who have sex with men. The most frequent anorectal manifestations were pus, tenesmus, rectal urgency, and mucous or haemopurulent discharge. The proctitis was mostly mild or moderate and, in some cases, it was accompanied by perianal lesions. Given the great polymorphism and unspecificity of the clinical manifestations of the disease, we warn on the presence of this form of rectal lymphogranuloma venereum in our setting. If Chlamydia trachomatis is detected, it should be genotyped, not only for the correct diagnosis and treatment but also for epidemiological surveillance. Where genotyping is not available, the disease must be considered as caused by the LGV biovar and treated accordingly.

ABSTRACT The aim of this paper is to provide an overview on the chemical composition of triterpenes in widespread used folk medicine species, through the development and validation of eleven compounds using HPLC-UV detection. The compounds were separated using isocratic elution, on a reverse phase column (Kinetex C18, 250 mm × 4.6 mm, 5 µm) with mobile phase consisted of acetonitrile:tetrahydrofuran (90:10, v/v), flow-rate of 0.5 ml/min and detection in 210 nm. Diverse validation parameters were successfully evaluated. The samples of Bauhinia variegata L., B. variegata var. candida Voigt, Fabaceae, Cecropia palmata Willd. and C. obtusa Trécul, Urticaceae, collected in 2012, 2013 and 2014 from Amazon were treated with two different solvents (ethyl acetate and chloroform) and analyzed by the proposed method. Stigmasterol, lupeol, β-sitosterol, β-amirin and α-amirin were found in all the studied plants. Highlighting the presence of oleanolic acid, maslinic acid in C. obtusa and C. palmata extracts, erythrodiol only in C. palmata, stigmasteol in B. variegata and α-amirin in B. variegata var. candida. Overall, ethyl acetate showed better performance as the extractor solvent than chloroform. Moreover, it could be used for the quality control of medicinal plants and to assess potential marker compounds.
