Resumo O acúmulo de produtos finais de glicação avançada (AGEs, do inglês advanced glycation end-products) provoca comprometimento morfofuncional dos rins. Os níveis de AGEs podem ser estimados de forma não invasiva por autofluorescência da pele (sAF). Exploramos se a sAF elevada prediz desfechos renais em indivíduos com diabetes tipo 2 (DT2). O estudo foi realizado como uma análise predefinida do Estudo Brasileiro sobre Diabetes, uma coorte prospectiva de centro único de adultos com DT2. Foram considerados os dados de 155 indivíduos acompanhados por até 1.716 dias. A incidência de eventos renais adversos maiores (MAKE, por sua sigla em inglês) foi de 9,6%. Indivíduos com sAF acima da mediana apresentaram maior incidência de MAKEs (4,6% vs. 21%; p = 0,002), com HR de 3,39 [IC 95%: 1,06–10,85; p = 0,040] após ajuste por idade e sexo. A alteração média da TFGe ajustada foi de 1,08 unidades (EP: 1,15; IC95%: –1,20, 3,37) no grupo de baixa sAF e de –5,19 unidades [EP: 1,93; IC95%: –9,10, –1,29] no grupo de elevada sAF (diferença entre sujeitos: F: 5,62; p = 0,019). O grupo sAF elevada apresentou maior prevalência de declínio rápido em comparação ao grupo sAF baixa (36,7% vs. 15,8%; p = 0,028). Em conclusão, a sAF elevada foi relacionada ao aumento da incidência de MAKEs e ao declínio mais rápido da TFGe entre indivíduos com DT2. Tal fato deve ser considerado pelos profissionais de saúde ao identificar indivíduos mais propensos a complicações renais relacionadas ao diabetes.

Abstract The accumulation of advanced glycation end-products (AGEs) elicits morphofunctional kidney impairment. AGEs levels can be noninvasively estimated by skin autofluorescence (SAF). We explored whether high SAF predicts kidney outcomes in type 2 diabetes (T2D) individuals. The study was conducted as a predefined analysis of the Brazilian Diabetes Study, a prospective single-center cohort of T2D adults. Data from 155 individuals followed for up to 1716 days were considered. The incidence of major adverse kidney events (MAKE) was 9.6%. Individuals with above-median SAF had a higher incidence of MAKEs (4.6% vs. 21%; p = 0.002), with an HR of 3.39 [95% CI: 1.06–10.85; p = 0.040] after adjustment by age and gender. The mean adjusted eGFR change was 1.08 units (SE: 1.15; 95%CI: –1.20, 3.37) in the low SAF and –5.19 units [SE: 1.93; 95%CI: –9.10, –1.29] in the high SAF groups (between-subject difference: F: 5.62, p = 0.019). The high-SAF group had a greater prevalence of rapid decliners than the low-SAF group (36.7% vs. 15.8%; p = 0.028). In conclusion, high SAF was related to increased incidence of MAKEs and faster decline in eGFR among T2D subjects. This should be considered by healthcare providers when identifying individuals more prone to diabetes-related kidney complications. endproducts end products (AGEs impairment SAF. .

Resumo Este estudo avaliou a atividade anestésica do óleo essencial de Lippia alba (OELA), quimiotipo linalool, em um peixe eurialino (robalo-peva Centropomus parallelus). No primeiro experimento, peixes foram expostos a 30, 80, 130, 180, 200 e 230 µL OELA L−1. O segundo experimento avaliou peixes pequenos e grandes com 180 µL OELA L-1. No terceiro experimento, avaliou-se taxa ventilatória por até 120 min em animais expostos a 5 e 10 µL OELA L−1. No quarto experimento, peixes anestesiados com 30 e 180 µL OELA L-1 foram avaliados nos tempos 0, 30 e 60 min após a recuperação anestésica para verificação de parâmetros bioquímicos e antioxidantes. Os melhores tempos de anestesia leve e profunda foram obtidos com 30 e 180 µL OELA L-1. Peixes maiores apresentaram anestesia e tempos de recuperação mais elevados. A taxa ventilatória aumentou em peixes expostos para OELA comparados ao grupo controle. Os níveis de glicose sanguínea e cortisol corporal foram maiores em peixes anestesiados com 180 µL OELA L-1. Robalos-peva expostos para OELA tiveram maior atividade de glutationa S-transferase e superóxido dismutase no fígado, sem afetar os níveis de catalase e peroxidação lipídica. O uso de 180 µL OELA L-1 é recomendado para anestesia de robalo-peva, pois aumentou taxa ventilatória e níveis de glicose sanguínea, cortisol corporal, e preveniu estresse oxidativo.

Abstract This study evaluated the anesthetic activity of essential oil from Lippia alba (EOLA), linalool chemotype in a euryhaline fish (fat snook Centropomus parallelus). In the first experiment, fish were exposed to 30, 80, 130, 180, 200, and 230 µL EOLA L−1. The second experiment evaluated smaller and larger fish with 180 µL EOLA L-1. In the third experiment, ventilatory rates (VR) for up to 120 min in animals during exposure to 5 and 10 µL EOLA L−1 were evaluated. In the fourth experiment, fish anesthetized with 30 and 180 µL EOLA L-1 were assessed at 0, 30, and 60 min after anesthesia recovery to evaluate biochemical and antioxidant parameters. The best mild and deep anesthesia times were obtained with 30 and 180 µL EOLA L-1, and larger fish had the highest times. The VR increased in fish exposed to EOLA. Blood glucose and whole-body cortisol levels were higher in fish anesthetized with 180 µL EOLA L-1. Fish exposed to EOLA had higher liver glutathione S-transferase and superoxide dismutase activities without affecting catalase and lipid peroxidation levels. The 180 µL EOLA L-1 is recommended for fat snook anesthesia because it increases VR, blood glucose, and whole-body cortisol levels and prevents oxidative stress.

RESUMO: O Bisfenol A (BPA) é um composto conhecido pela sua ação direta na próstata. A morfogênese prostática é um período crítico e a interferência de qualquer composto pode acarretar danos permanentes a este órgão. Dessa forma, o presente estudo avaliou os aspectos morfológicos resultantes da administração gestacional e lactacional ao BPA, indol-3-carbinol (I3C) e genisteína (GEN) em ratos machos pré-púberes. Fêmeas prenhes da linhagem Sprague-Dawley foram divididas em quatro grupos experimentais e receberam: C: Controle; B: BPA (10 µg/Kg); BG: BPA+GEN (5 mg/Kg); BI: BPA+I3C (20 mg/Kg) do dia gestacional 17 até o dia pós-natal (DPN) 21. Após a eutanásia no DPN22 a próstata foi coletada e processada. O BPA quando administrado isoladamente ocasionou redução do compartimento estromal em comparação ao grupo C (P = 0,039). Essa redução foi revertida nos grupos que foram submetidos à administração de GEN (P = 0,019) ou I3C (P = 0,017). Os grupos tratados com BPA (P < 0,0001) e os fitoestrógenos (P < 0,0001) apresentaram redução da altura epitelial quando comparados com o grupo C. Tais modificações encontradas nas análises estéreo-morfométricas não foram evidenciadas pela análise fractal (P = 0,569). Verificou-se aumento da área ocupada pelo colágeno nos grupos submetidos à administração de BPA (P < 0,0001) e fitoestrógenos (P < 0,0001) em relação ao grupo C. Com relação ao padrão de distribuição dessas fibras, a análise fractal revelou maiores valores em todos os grupos tratados (P < 0,0001). Assim, verificou-se que o BPA induziu remodelação no estroma prostático, sem influência dos fitoestrógenos, o que pode afetar o desenvolvimento glandular e provocar alterações histopatológicas na vida adulta.

ABSTRACT: Bisphenol A (BPA) is a compound known for its direct action on the prostate. Prostatic morphogenesis is a critical period when interference by any compound could permanently damage the organ. As such, the present study evaluated the morphological aspects resulting from gestational and lactational administration of BPA, indole-3-carbinol (I3C) and genistein (GEN) in prepubescent male rats. Pregnant Sprague Dawley females were allocated into 4 experimental groups and received the following: C: Control (no treatment); B: BPA (10 µg/Kg); BG: BPA+GEN (5 mg/Kg); BI: BPA+I3C (20 mg/Kg) from gestation day (GD) 17 to postnatal day (PND) 21. After euthanasia on PND22, the prostate was collected and processed. When administered alone, BPA reduced the stromal compartment when compared to group C (P = 0.039). This decline was reversed in the groups submitted to GEN (P = 0.019) or I3C (P = 0.017). The groups treated with BPA (P < 0.0001) and the phytoestrogens (P < 0.0001) exhibited decreased epithelial height in relation to the control group. These changes were observed in stereological and morphometric analyses, but not in fractal analysis (P = 0.569). The area occupied by collagen increased in groups treated with BPA (P < 0.0001) and phytoestrogens (P < 0.0001) in relation to controls, while collagen distribution values were higher in all the treated groups (P < 0.0001), according to fractal analysis. Thus, BPA induced prostrate stroma remodeling with no influence from the phytoestrogens, which may affect glandular development and cause histopathological changes in adulthood.

Abstract The jabuticaba bark is rich in anthocyanins and fibers, and its use may be of industrial interest. In the food sector, its used as an ingredient in the production of fermented products, liqueurs or enriched flours. It also has pharmaceutical and cosmetic applications. The objective was to evaluate the effect of pretreatment and fresh use of jabuticaba peels in the extraction of total phenolic compound (TPC) and total anthocyanin (TA) contents with and without ultrasound assistance and in the sequential extraction of pectin from the residue. In the TPC and TA extraction, a 3x2 factorial design was used. For conventional anthocyanin extraction (CAE), occurred in an incubator under agitation. For ultrasound-assisted anthocyanin extraction (UAE) was utilized an ultrasonic homogenizer with probe (20 kHz, 160 W). The extracts were quantified (TPC, TA, antioxidant activity and color). The residues were characterized and used for sequential pectin extraction, which was quantified and characterized. The results were subjected to analysis of variance. Fresh jabuticaba peel is a residue that can be used to sequentially extract phenolic compounds, particularly anthocyanins and pectin. The use of ultrasound (UAE) was less efficient than CAE for extracting TPC and TA or performing sequential extraction on all pretreatment peels. fibers interest sector products flours applications (TPC (TA x 3x CAE, , (CAE) agitation ultrasoundassisted assisted UAE (UAE 20 (2 kHz 16 W.

The growth of the oil and gas industry implies an understanding of corrosion and ways to mitigate pipeline failures. The objective of this research is to evaluate the propagation of localized corrosion induced by flow in different concentrations of sodium chloride and in the presence of corrosion inhibitor, associated with the wall shear stress. The API X65 steel specimens were drilled, with the purpose of simulating corrosion pits, and coupled to a modified ASTM G170 rotating cage.The experimental conditions were: (1) desaerated medium in the presence of CO2 under 5 bar, 120°C and concentrations of 0.1% or 10% sodium chloride; (2) aerated medium without CO2 at 40°C, without or with corrosion inhibitor. To evaluate the shear stress, Computational Fluid Dynamics (CFD) was used to understand the distribution on the surface of the samples. The results showed that the chloride concentration influenced the formation of the FeCO3 film and the corrosion rate. Furthermore, it was observed that the variation in diameter was more pronounced for the pits that had the smallest initial diameter, in all conditions evaluated. The highest values of diameter variation did not correspond to the highest values of shear stress imposed on each artificial pits. failures inhibitor X X6 drilled G G17 cageThe cage 1 (1 CO bar 120C C 120 01 0 0.1 10 2 (2 40C 40 40°C CFD (CFD samples FeCO rate Furthermore evaluated G1 ( 12 0. 4

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 Leaf litter is an important component related to nutrient cycling and conservation of soil biodiversity. In this context, the objective of our study was to investigate the relationship between soil and leaf litter in different forest communities in sub-regions of the Pantanal (Nhecolândia and Abobral/Miranda). To this end, we collected soil and leaf litter samples from 152 sample plots divided in physiognomies regionally called as Cordilheira, Capão, Murundu, Corixo and Cambará/Canjiqueira forest. In the laboratory, analytical determinations were conducted for 22 soil attributes and 11 elements of the chemical composition of the leaf litter. The forest communities showed a great well-defined edaphic gradient encompassing environments with high natural fertility soils (Capão and Cordilheira Abobral/Miranda), acidic soils with a high proportion of soluble Al3+ (Cambará/Canjiqueira, and Corixo), and poorly developed soils with a predominantly sandy texture (Nhecolândia region, Cordilheira and Murundu). Soil attributes are significantly related to the chemical composition of litter, as indicated by correlations between N, P, Ca, Mg, Mn and the C/N ratio with physical, chemical and soil organic matter attributes. This study revealed the interaction of soils with the chemical composition of litter, constituting an ecosystem service, in forest communities in the Brazilian Pantanal. biodiversity context subregions sub regions Nhecolândia Abobral/Miranda.

Resumo Fundamento: A rigidez arterial aumentada é considerada atualmente um fator de risco independente para fibrilação atrial. No entanto, os mecanismos fisiopatológicos dessa arritmia ainda constituem uma lacuna no conhecimento a ser explorada. Objetivos: Investigar a existência de uma associação entre rigidez arterial e densidade de extrassístoles atriais em indivíduos hipertensos sem fibrilação atrial. Métodos: Estudo transversal com pacientes hipertensos sem fibrilação atrial diagnosticada, que foram estudados com ecocardiografia speckle-tracking para avaliar o strain do átrio esquerdo e velocidade de onda de pulso carótido-femoral (VOPcf) para avaliar a rigidez arterial. Todos os pacientes foram submetidos ao Holter de 24 horas e exames laboratoriais. O nível de significância adotado foi de p<0,05. Resultados: Setenta pacientes de um único centro sem doença cardiovascular evidente foram incluídos. A VOPcf correlacionou-se com uma maior densidade de extrassístoles atriais no Holter de 24 horas, independentemente da massa ventricular esquerda [1,48 (1,08- 2,03), p = 0,005]. Uma VOPcf aumentada correlacionou-se com valores reduzidos de strain atrial esquerdo, com coeficientes de correlação de Spearman de −0,27 (p= 0,027) e −0,29 (p = 0,018) para strains bidimensionais de reservatório e de conduto, respectivamente. Conclusão: Neste estudo com pacientes hipertensos, foi possível demonstrar uma associação entre rigidez arterial e maior densidade de arritmias atriais. Além disso, a rigidez arterial associou-se com valores mais baixos de strain atrial esquerdo das funções de reservatório e de conduto.

Abstract Background: Increased arterial stiffness is currently an independent risk factor for atrial fibrillation, but the pathophysiological mechanisms of this arrhythmia remain an area of knowledge gap to be explored. Objectives: To investigate the existence of an association between arterial stiffness and the density of premature atrial contractions (PACs) in hypertensive individuals without atrial fibrillation. Methods: Cross-sectional study with hypertensive patients without diagnosed atrial fibrillation, who were studied with speckle-tracking echocardiography to assess left atrial (LA) strain and carotid-femoral pulse wave velocity (cfPWV) to assess arterial stiffness. All patients underwent 24h-ECG Holter and laboratory tests. Significance level was set at p<0.05. Results: Seventy participants from a single centre without overt cardiovascular disease were included. The cfPWV was correlated with higher density of PACs in 24h-Holter monitoring, independently of LV mass index (1.48 [1.08-2.03], p-value 0.005). Increased cfPWV was correlated with decreased LA strain values, with Spearman correlation coefficients of −0.27 (p-value 0.027) and −0.29 (p-value 0.018) for reservoir and conduit 2D Strain, respectively. Conclusions: In this study with hypertensive patients, it was possible to demonstrate an association between arterial stiffness and higher density of atrial arrhythmias. Furthermore, arterial stiffness was associated with lower left atrial strain values for reservoir and conduit functions.

Microbiologically influenced corrosion is a common problem in the oil and gas industry. It is a type of corrosion induced by biofilm-forming microorganisms such as sulfate-reducing bacteria which produces corrosive compounds as a product of their respiration. The most indicated treatment for the issue is the use of biocides, chemical substances used to kill microbes. However, biocides are corrosive to many materials, making their selection a problem. The 2,2-dibromopropanediamide (BDNPA) is a biocide used to control the growth of a wide range microorganisms. There is a literature gap for selecting materials that can be used with DBNPA Biocide without risk of corrosion. Hence, this research is dedicated to investigating the corrosion behaviour of commonly used alloys in a DBNPA solution. This work evaluated 11 alloys commonly used in the laboratory for the manufacture of instrumentation piping. Anodic polarization tests and 30 days immersion tests were carried out in a 100% DBNPA solution at two temperatures (25 and 40 ºC). Among the analysed alloys, only 4 were approved by the tests in all tested temperature ranges (Titanium Grade 2, Hastelloy C276, Inconel 625 and Superduplex Steel SAF 2507). These alloys did not present a localized corrosion process in any of the 30-day immersion tests, in addition, they obtained a significant passivation domain in the anodic polarization test at 40 ºC. The remaining alloys (AISI 304, AISI 316, AISI 317, AISI 321, AISI 347, Monel 400) were not approved in all temperature ranges tested for transport and storage of 100% BDNPA biocide solution. industry biofilmforming biofilm forming sulfatereducing sulfate reducing respiration microbes However 2,2dibromopropanediamide 22dibromopropanediamide dibromopropanediamide 2,2 2 (BDNPA Hence 1 piping 3 100 25 (2 ºC . ºC) Titanium C276 C 62 2507. 2507 2507) 30day day addition 304 316 317 321 347 400 2dibromopropanediamide 22 10 ( C27 6 250 31 32 34 C2

Abstract The loss and reduction of forest cover are related to soil degradation and the reduction of environmental services. Reforestation is a key element to fight global warming. Replanting deforested areas with native forest species increases the survival and success of the plantation. It was proposed that, according to the requirements of altitude, slope, temperature, precipitation, topography, soil type, texture and depth, and through the use of the BIOCLIM tool, it is possible to identify and quantify the potential reforestation areas in the state of Guanajuato by six forest species of the Fabaceae family. Based on climatic and edaphic requirements, Prosopis laevigata was the taxon with the largest potential area for reforestation with 278 102 ha of good and very good suitability, Albizia occidentalis occupied a surface area of 230 239 ha, 157 491 ha were estimated for Acacia farnesiana (synonym of Vachellia farnesiana), 149 434 ha for Lysiloma divaricata (synonym of Lysiloma divaricatum), 120 968 ha for Leucaena esculenta, and merely 3 633 ha for Acacia pennatula (synonym of Vachellia pennatula). The delimited areas are the zones where it is possible to plant these species and guarantee a greater probability of survival and success in reforestation works, and with it, the restoration of the landscape.
Resumen La pérdida y reducción de la cubierta forestal están relacionadas con la degradación del suelo y la disminución de servicios ambientales.

RESUMO: Neoplasias mamárias caninas com componentes mesenquimais malignos, como carcinossarcomas e sarcomas, são um grupo de neoplasias pouco frequentes e histologicamente heterogêneas e pouco se sabe sobre o comportamento biológico das variantes histogênicas. O objetivo desse estudo é comparar as características anatomopatológicas e a expressão imunoistoquímica de COX-2 de diferentes subtipos histológicos de carcinossarcomas e sarcomas. Foram estudados 23 carcinosarcomas e 17 sarcomas da glândula mamária de cadelas. Os prontuários médicos foram revisados para obtenção de dados clínicos. Posteriormente, as lâminas histológicas foram avaliadas para acessar os subtipos mesenquimais, necrose, invasão vascular, grau histológico, metástase linfonodal. A imunoistoquímica foi realizada para avaliar a expressão de COX-2. Os tipos encontrados de proliferação mesenquimal maligna foram osteossarcoma (23/40), fibrossarcoma (7/40), lipossarcoma (6/40) e condrossarcoma (4/40). A diferenciação osteossarcomatosa foi predominante entre os sarcomas e carcinossarcomas e foi associado com invasão vascular (P=0,006) e metástase linfonodal (P=0,014). Uma expressão alta de COX-2 foi detectada em 14,3% dos carcinossarcomas (células carcinomatosas e/ou sarcomatosas) e 27,3% dos sarcomas. Os carcinossarcomas e sarcomas apresentaram características clínicas e patológicas semelhantes e se desenvolveram como tumores grandes, com necrose intratumoral e predomínio de alto grau histológico, mas com baixa frequência de invasão vascular e metástase distante. Os subtipos osteossarcomatosos apresentaram características mais agressivas quando comparados com subtipos não osteossarcomatosos.

ABSTRACT: Canine mammary neoplasms with malignant mesenchymal components, such as carcinosarcomas and sarcomas, belong to an uncommon and histologically heterogeneous group. Little is known about the biological behavior of these histogenic variants. This study aimed to compare the clinicopathological characteristics and the COX-2 immunohistochemical expression of different histologic subtypes of carcinosarcomas and sarcomas. Samples of 23 carcinosarcomas and 15 sarcomas from the mammary glands of female dogs were studied. Medical records were reviewed to obtain clinical data. Subsequently, histology microscope slides were analyzed to assess for mesenchymal subtypes, necrosis, vascular invasion, histologic grades, and lymph node metastasis. Immunohistochemistry was used to assess the COX-2 expression. The malignant mesenchymal proliferation was categorized into osteosarcomas (23/40), fibrosarcomas (5/40), liposarcomas (6/40) and chondrosarcomas (4/40). The osteosarcomatous differentiation was the most predominant type among the sarcomas and carcinosarcomas and was associated with vascular invasion (P=0.010) and lymph node metastases (P=0.014). High COX-2 expression was detected in 14.3% of the carcinosarcomas (carcinoma and/or sarcoma cells) and 27.3% of the sarcomas. The carcinosarcomas and sarcomas had similar clinical and pathological characteristics and developed as large tumors, with intratumoral necrosis and a predominance of high histologic grades, although the frequency of vascular invasion and lymph node metastasis was low. Osteosarcoma subtypes presented more aggressive characteristics than non-osteosarcoma subtypes.

ABSTRACT Introduction Haploinsufficiency of the hematopoietic transcription factor GATA2 is associated with a broad spectrum of diseases, including infection susceptibility and neoplasms. We aimed to investigate GATA2 variants in patients with non-tuberculous mycobacterial (NTM) and/or fungal infections (FI) without known immunodeficiencies. Method We performed GATA2 genotyping in patients with NTM and/or FI. Results Twenty-two patients were enrolled (seventeen FI, four NTM and one with both infections). The pathogenic variant NG_029334.1:g.16287C>T was found in one patient (4.5%) and two asymptomatic offsprings. We also found the likely-benign variant NG_029334.1:g.12080G>A (rs2335052), the benign variant NG_029334.1:g.16225C>T (rs11708606) and the variant of uncertain significance NG_029334.1:g.16201G>A (rs369850507) in 18.2%, 27.3%, and 4.5% of the cases, respectively. Malignant diseases were additionally diagnosed in six patients. Conclusion Although detected in 45.4% of the patients, most GATA2 variants were benign or likely benign. Identifying a pathogenic variant was essential for driving both the patient's treatment and familial counseling. Pathogenic variants carriers should receive genetic counseling, subsequent infection prevention measures and malignancies surveillance. Additionally, case-control genotyping should be carried out in Brazil to investigate whether the observed variants may be associated with susceptibility to opportunistic infections and/or concurrent neoplasms.

RESUMO: Objetivou-se avaliar os efeitos da substituição do milho pelo sorgo inteiro e moído sobre o desempenho zootécnico de perus fornecido no período de um a 28 dias de idade. Foram utilizados 3.960 perus machos da linhagem Nicholas, divididos em seis tratamentos: A) Sorgo inteiro (100%Si); B) Milho moído (100%M); C) 75% Milho moído + 25% Sorgo moído (75%M25%S); D) 50% Milho moído + 50% Sorgo moído (50%MS); E) 25% Milho moído + 75% Sorgo moído (25%M/75%S) e F) Sorgo moído (100%Sm). Aos sete dias de idade o peso vivo foi igual entre os tratamentos (média de 164 g por ave). Aos 28 dias a percentagem de peito, coxa-sobrecoxa e asas mantiveram-se constantes na dieta a base de milho, ou substituições parciais e totais pelo sorgo grão moído ou inteiro. O comprimento do intestino delgado foi menor no tratamento B e C. A digestibilidade da fração lipídica da ração (DEE) foi significativamente maior na ração com o sorgo moído. O tratamento base sorgo grão moído mostrou o mesmo resultado para milho moído na composição de matéria seca (MS) e de matéria mineral (MM MS) da carcaça dos perus aos 28 dias. O sorgo grão moído influenciou a parcela lipídica das carcaças (EE MS). Desta forma, conclui-se que o grão de sorgo inteiro apresentou os mesmos resultados do que sorgo moído e milho moído para desempenho zootécnico, massa muscular da carcaça e morfometria das vísceras em peruzinhos do alojamento a 28 dias de idade.

ABSTRACT: The study evaluated the effects of replacing corn with whole and ground sorghum on the zootechnical performance of turkeys fed from one to 28 days of age. A total of 3,960 male Nicholas turkeys were used, divided into six treatments: A) Whole sorghum (100%Sw); B) Ground corn (100%Cg); C) 75% Ground Corn + 25% Ground Sorghum (75%Cg/25%Sg); D) 50% Ground Corn + 50% Ground Sorghum (50%Cg/50%Sg); E) 25% Ground Corn + 75% Ground Sorghum (25%Cg/75%SG) and F) Ground Sorghum (100%Sg). At seven days, live weight was the same between treatments (164 g per bird). At 28 days, the percentage of breast, thigh-drumstick, and wings remained constant in the corn-based diet or partial and total replacements by ground or whole sorghum grain. The length of the small intestine was shorter in treatments B and C. The digestibility of the lipid fraction of the diet (DEE) was significantly higher in the diet with ground sorghum. The treatment based on ground sorghum grain showed the same result for ground corn in the dry matter (DM) and mineral matter (MM DM%) composition of the turkey carcass at 28 days. Ground sorghum influenced the lipid portion of the carcasses (EE DM%). Thus, it is concluded that whole sorghum grain presented the same results as ground sorghum and ground corn for zootechnical performance, carcass muscle mass, and viscera morphometry in turkeys at 28 days of age.

Resumen Gymnophthalmidae es una Familia diversa de lagartos Sudamericanos de tamaño pequeño a mediano. En Paraguay se conocen actualmente siete especies. Entre estas, Colobosaura modesta y Micrablepharus maximiliani son dos especies poco muestreadas en el país: C. modesta era solamente conocida en dos localidades en los Departamentos de Amambay y San Pedro, mientras que M. maximiliani se conoce de los departamentos Central, Cordillera, Paraguarí y San Pedro. Durante dos estudios de campo en 2022, capturamos un individuo de C. modesta y tres de M. maximiliani. El registro de C. modesta se encuentra a 198 km al oeste de la localidad conocida más cercana y es la tercera localidad confirmada en el país, la primera en el Departamento de Concepción y la primera asociada al Chaco Húmedo. Los registros de M. maximiliani se encuentran a 81, 131 y 137 km al norte de la localidad conocida más cercana y son los primeros registros de los departamentos de Concepción y Amambay. Proveemos la caracterización del hábitat donde los encontramos y discutimos su estado de conservación en Paraguay.
Abstract Gymnophthalmidae is a highly diverse family of small to medium sized South American lizards. In Paraguay, seven species are currently known. Among these, Colobosaura modesta and Micrablepharus maximiliani are two poorly sampled species in the country: C. modesta was only recorded in two localities in Amambay and San Pedro Departments, whilst M. maximiliani was recorded in Central, Cordillera, Paraguarí and San Pedro Departments. During two field surveys in 2022 we captured one C. modesta and three M. maximiliani individuals. The C. modesta record is 134.7 km west from the nearest known locality, and it is the third confirmed locality in the country, the first in the Concepción Department and the first associated with the Humid Chaco. The M. maximiliani records are 81, 131 and 137 km north from the nearest known locality and are the first records from Concepción and Amambay Departments. We provide habitat characterization for where the lizards were found and discuss their conservation status in Paraguay.
