Abstract Tea is identified as the second most consumed drink in the world, and its frequent intake is related to several benefits to human health, considering its antimutagenic, anticarcinogenic, antimicrobial, anti-inflammatory, antihistamine, diuretic, calming, and above all, antioxidant effects. These effects are often associated with the action of the phenolic compounds contained in these infusions. In Brazil, among the most consumed infusions are the teas of chamomile (Matricaria chamomilla L.), lemongrass (Cymbopogon citratus (D.C.) Stapf), lemon balm (Melissa officinalis L.), anise (Pimpinella anisum L.), yerba mate (Ilex paraguariensis A. St.-Hil), peppermint (Mentha piperita L.), and green/black tea (Camellia sinensis L.). Therefore, said popularity is the reason why the mentioned species were chosen to be evaluated on inflammatory enzymes. The activity of phospholipases A2 was reduced by more than 25% after treatment with black tea and yerba mate. The most significant inhibition of protease activity was observed after incubation with black tea (40.74%), green tea (31.48%) and yerba mate (25.93%). Infusions of black and green tea reduced hemolysis in semisolid and liquid media, and for the latter, reductions of up to 50% of hemolytic activity were observed, indicating an anti-inflammatory potential of the samples. Plasma incubations with green tea, black tea and lemon balm and subsequent addition of venom (1:10 ratio; tea:PBS, v:v) prolonged the coagulation time of citrated plasma by approximately twice compared to the positive control. All controls with pure tea had a thrombolytic character, in higher proportions than the venom control, especially chamomile (273.55% dissolution). Phenolic compounds derived from phenolic acids, flavonoids, and tannins are identified as the main agents that promote the biological effects observed in this study. This is mainly due to their anti-catalytic properties exerted on inflammatory enzymes and as chelating agents of enzymatic co-factors. The evaluated teas showed potential for nutraceutical use, thus pointing to the possibility of use as an adjuvant in the treatment of diseases linked to hemostasis. world health antimutagenic anticarcinogenic antimicrobial antiinflammatory, antiinflammatory anti inflammatory, antihistamine diuretic calming all Brazil Matricaria L., L L. , L.)

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.

RESUMO O uso de dietas com alta densidade energética e aditivos que potencializem o aproveitamento energético se faz necessário na terminação de bovinos em confinamento. O objetivo do presente estudo foi avaliar o desempenho, o comportamento ingestivo, a digestibilidade aparente da dieta e as características de carcaça de novilhos confinados, alimentados com concentrados de diferentes fontes energéticas, um derivado de fontes amiláceas e outro de fontes lipídicas, associados ou não com lecitina integral de soja, na dose de 40g animal dia-1. O delineamento experimental foi o de blocos inteiramente ao acaso, em esquema fatorial 2 x 2. A associação da lecitina integral de soja com o concentrado de fonte energética lipídica melhorou a digestibilidade da matéria seca e o rendimento de carcaça dos animais (76,03% e 57,20%, respectivamente). O concentrado de fonte energética lipídica teve maior digestibilidade do extrato etéreo, e os animais alimentados com este possuíram maior rendimento de carcaça (84,18% e 56,85%, respectivamente). A lecitina integral de soja isolada promoveu redução no pH fecal em virtude de uma maior fermentação de carboidratos e ácidos graxos no lúmen intestinal. Utilizar lecitina integral de soja associada com concentrado energético de fonte lipídica é recomendado devido a suas melhorias no aproveitamento da dieta e no rendimento de carcaça. confinamento desempenho ingestivo confinados energéticas lipídicas g dia1. dia1 dia 1. 1 dia-1 acaso 76,03% 7603 76 03 (76,03 5720 57 20 57,20% respectivamente. respectivamente . respectivamente) etéreo 84,18% 8418 84 18 (84,18 5685 56 85 56,85% intestinal dia- 76,03 760 7 0 (76,0 572 5 57,20 84,18 841 8 (84,1 568 56,85 76,0 (76, 57,2 84,1 (84, 56,8 76, (76 57, 84, (84 56, (7 (8 (
ABSTRACT Diets with high energy density and additives that enhance energy use are necessary for finishing feedlot cattle. The objective of the present study was to evaluate the performance, ingestive behavior, apparent digestibility of the diet and the carcass traits of feedlot steers fed concentrates from different energy sources, one derived from starchy sources and the other, from lipid sources, combined or not with whole soy lecithin, at a dose of 40 g animal day-1. The experimental design was completely randomized blocks, in a 2 x 2 factorial arrangement. The combination of whole soy lecithin with the lipid energy source concentrate increased the dry matter digestibility and the carcass yield of the animals (76.03% and 57.20%, respectively). The lipid energy source concentrate showed higher ether extract digestibility and animals fed on it had higher carcass yield (84.18% and 56.85%, respectively). Whole soy lecithin promoted a reduction in fecal pH due to a greater fermentation of carbohydrates and fatty acids in the intestinal lumen. Using whole soy lecithin combined with energy concentrate from a lipid source is recommended due to its improvements in the use of the diet and in the carcass yield. cattle performance behavior other 4 day1. day1 day 1. 1 day-1 blocks arrangement 76.03% 7603 76 03 (76.03 5720 57 20 57.20% respectively. respectively . respectively) 84.18% 8418 84 18 (84.18 5685 56 85 56.85% lumen day- 76.03 760 7 0 (76.0 572 5 57.20 84.18 841 8 (84.1 568 56.85 76.0 (76. 57.2 84.1 (84. 56.8 76.

RESUMO Objetivo: Avaliar o efeito antifúngico da incorporação de diferentes concentrações do óleo essencial Cymbopogon citratus (capim santo), em polimetilmetacrilato (PMMA) contra Candida albicans. Métodos: Cinquenta corpos de prova foram confeccionados e divididos em cinco grupos: Grupo 1, PMMA + 10% de óleo essencial (n=10); Grupo 2, PMMA + 15% de óleo essencial (n=10); Grupo 3, PMMA + 20% de óleo essencial (n=10); Grupo 4, PMMA + 25% de óleo essencial (n=10); Grupo 5, PMMA (n=10). O pó de PMMA foi misturado ao monômero e a mistura foi colocada em cavidades em forma de disco medindo 15 mm de diâmetro por 2 mm de espessura. Para avaliar a atividade antifúngica dos espécimes experimentais, foi testada a cepa padrão de Candida albicans. Após a incubação, foi realizada a contagem de colônias de cada placa por meio de um contador digital de colônias, obtendo-se o número de unidades formadoras de colônias (UFC) e para isso foi aplicado o teste de Kruskal-Wallis. Resultados: Houve diferença estatisticamente significativa na contagem de UFC de Candida albicans como consequência da adição do óleo essencial de Cymbopogon citratus ao PMMA (p < 0,001) e os valores foram significativamente maiores em comparação com todos os outros grupos, quando o essencial óleo foi incorporado como incorporado ao PMMA na concentração de 20%. Nas demais concentrações, não houve diferença nos valores em relação ao Grupo Controle sem óleo essencial de Cymbopogon citratus. Conclusão: A resina acrílica com o óleo essencial incorporado a ela em diferentes concentrações não apresentou efeito contra o desenvolvimento do gênero Candida.

ABSTRACT Objective: Evaluated the antifungal effect of the incorporation of different concentrations of the essential oil Cymbopogon citratus (capim santo), into polymethylmethacrylate (PMMA) against Candida albicans. Methods: Fifty specimens were fabricated and divided into five groups: Group 1, PMMA + 10% essential oil (n=10); Group 2, PMMA + 15% essential oil (n=10); Group 3, PMMA + 20% essential oil (n=10); Group 4, PMMA + 25% essential oil (n=10); Group 5, PMMA (n=10). PMMA powder was mixed with the monomer and the mixture was placed in disc-shaped cavities measuring 15 mm in diameter, 2 mm thick. To evaluate the antifungal activity of the experimental specimens, the standard strain of Candida albicans was tested. After incubation, the colony count of each plate was performed using a digital colony counter, obtaining the number of colony forming units (CFU) and the Kruskal-Wallis test was applied. Results: There was statistically significant difference in the CFU count of Candida albicans as a consequence of the addition of Cymbopogon citratus essential oil to PMMA (p < 0.001) and values were significantly higher in comparison with those of all the other groups, when the essential oil was incorporated as incorporated into the PMMA in the concentration of 20%. In the other concentrations, no difference in values was observed in comparison with the Control Group without essential oil of Cymbopogon citratus. Conclusion: The acrylic resin with the essential oil incorporated into it in different concentrations provided no effect against development of the genus Candida.

ABSTRACT The expression ‘you need to know to conserve’ is a well-known cliche among biologists. Documenting the richness of a group of organisms is the first step towards understanding biodiversity and preparing efficient conservation plans. In this context, many efforts have been made to quantify the number of species on Earth and estimate the number of species still unknown to science. A few countries have complete and integrated databases estimating the approximate number of species recorded for their territory, particularly in the Global South. In Brazil, a country of continental dimensions, revealing the richness of the second most diverse clade of invertebrates (=Mollusca) has been a goal of taxonomists. Recently, in an unprecedented, collective, and integrated effort among Brazilian malacologists, it was possible to estimate how many valid species of molluscs are there in Brazil. In this effort, more than 30 mollusc experts joined together to update the Taxonomic Catalogue of the Brazilian Fauna (TCBF), a governmental website that allows a quick and real-time updating of all Metazoan. So far, more than 5,000 updates have been made in TCBF, indicating the presence of 3,552 valid species of molluscs in Brazil, distributed among the main clades as follows: Caudofoveata (10 spp.), Solenogastres (6 spp.), Polyplacophora (35 spp.), Scaphopoda (43 spp.), Cephalopoda (92 spp.), Bivalvia (629 spp.) and Gastropoda (2,737 spp.). The present study, in addition to demonstrating for the first time the richness of Brazilian molluscs, also presents the state of the art of this important phylum of invertebrates highlighting its most representative and neglected groups. you conserve wellknown well known biologists plans context science territory South Brazil dimensions =Mollusca Mollusca (=Mollusca taxonomists Recently unprecedented collective malacologists 3 TCBF , (TCBF) realtime real Metazoan far 5000 5 000 5,00 3552 552 3,55 follows 10 (1 spp., spp spp. 6 ( 35 (3 43 (4 92 (9 629 (62 2,737 2737 2 737 (2,73 spp.. . study groups (TCBF 500 00 5,0 355 55 3,5 1 4 9 62 2,73 273 73 (2,7 50 0 5, 3, 2,7 27 7 (2, 2, (2

Abstract Background: The COVID-19 pandemic may affect youth’s physical and mental well-being, partially because of the countries’ rules to contain the virus from spreading. However, there is still uncertainty about the impact of physical distancing on youth’s mental health. We aimed to estimate the prevalence of feeling agitated, anxious, down, sad, or low mood (FNF) due to physical distance measures and verify which factors are associated with young Portuguese and Brazilian people. Methods: We used cross-sectional data from the instrument “COVID-19 Barometer: Social Opinion” in Portugal (March 2020 and September 2021) and from “COVID-19 Social Thermometer” in Brazil (August 2020 to April 2021); these surveys included data regarding the health and socioeconomic impact on the population. The health and sociodemographic variables of the two countries were summarized as absolute and relative frequencies. A multivariable logistic regression model was fit by country to estimate the relation between FNF and selected variables of interest. Results: Approximately 36% of the sample studied reported anxiety, agitation, sadness, or low mood almost every day in Portugal and 52% in Brazil due to physical distancing. In Portugal, having more than two comorbidities represented a greater chance of experiencing FNF every day or almost every day (odds ratio [OR] = 1.51 [CI: 1.22-1.87]) than those without comorbidities. In contrast, having a university education level represented a protector factor (OR = 0.76 [CI: 0.67-0.88]). In Brazil, being unemployed increased the chance of FNF compared to students (OR = 11.2). Conclusions: Physical distancing measures have impacted the mental well-being of the young population in Portugal and Brazil. The countries must make a quick effort to attend to and protect young people’s well-being and mental health in the changing context of the current pandemic.
Resumo Introdução: A pandemia do COVID-19 pode afetar o bem-estar físico e mental dos jovens, em parte por causa das regras dos países para conter a propagação do vírus. No entanto, ainda há incerteza sobre o impacto do distanciamento físico na saúde mental dos jovens. Objetivou-se estimar a prevalência de sentir-se agitado, ansioso, deprimido ou triste (FNF) devido a medidas de distância física e verificar quais fatores estão associados a jovens portugueses e brasileiros. Métodos: Utilizamos dados transversais do instrumento “COVID-19 Barômetro: Social Opinião” em Portugal (março de 2020 até setembro de 2021) e do “COVID-19 Social termômetro” no Brasil (agosto de 2020 até abril de 2021); essas pesquisas incluíram dados sobre o impacto na saúde e socioeconômicos da população. As variáveis de saúde e sociodemográficas dos dois países foram resumidas em frequências absolutas e relativas. Um modelo de regressão logística multivariável foi ajustado por país para estimar a relação entre a frequência de sentimentos negativos (FNF) e variáveis selecionadas de interesse. Resultados: Aproximadamente 36% da amostra estudada relatou ansiedade, agitação, tristeza ou mau humor; quase todos os dias em Portugal e 52% no Brasil devido ao distanciamento físico. Em Portugal, ter mais de duas comorbidades representou maior chance de apresentar FNF todos os dias ou quase todos os dias (OR = 1,51 [IC 1,22 -1,87]) do que aqueles sem comorbidades. Em contrapartida, ter nível universitário representou fator protetor (OR = 0,76 [IC 0,67-0,88]). No Brasil, estar desempregado aumentou a chance de FNF em relação aos estudantes (OR = 11,2). Conclusões: As medidas de distanciamento físico têm impactado o bem-estar mental da população jovem em Portugal e no Brasil. Os países devem fazer um esforço rápido para atender e proteger o bem-estar e a saúde mental dos jovens no contexto de mudança da atual pandemia.

RESUMO: Varronia curassavica é uma espécie medicinal nativa no Brasil e sua propriedade anti-inflamatória é atribuída aos compostos α-humuleno e β-cariofileno. O objetivo foi estudar a variabilidade de população de V. curassavica. Foram coletadas folhas de 40 indivíduos de população natural, sendo estas transferidas para frascos de vidro (2 mL). Os voláteis foram extraídos e analisados por headspace estático, associado à cromatografia gasosa, acoplada à espectrometria de massas (HS-CG-EM). Detectou-se 17 compostos: monoterpenos (1,6% - 68%) e sesquiterpenos (25,7% - 79,0%), incluindo o α-humuleno e o β-cariofileno. A análise multivariada foi realizada para estimar a dissimilaridade dos indivíduos, a qual separou quatro grupos. O grupo I foi caracterizado pela presença do α-pineno, os grupos II e IV do β-cariofileno e o grupo III do β-pineno. O teor do α-humuleno apresentou pequenas variações, enquanto o do β-cariofileno contribuiu mais para a variabilidade da população. É o primeiro relato de análise da composição química de compostos voláteis de V. curassavica utilizando a técnica HS-GC-MS.
ABSTRACT: Varronia curassavica is a medicinal species native to Brazil; its anti-inflammatory properties are attributed to α-humulene and β-caryophyllene. This study to investigated the population variability of V. curassavica. Leaves were collected from 40 individuals of a natural population and transferred to glass flasks (2 mL). The volatiles were extracted and analyzed using static headspace gas chromatography coupled with mass spectrometry (HS-GC-MS). A total of 17 compounds were detected: monoterpenes (1.6% - 68%) and sesquiterpenes (25.7% - 79.0%), including α-humulene and β-caryophyllene. Multivariate analysis was performed to estimate the dissimilarity of individuals separated the compounds into four groups. Group I was characterized by the content of α-pinene, groups II and IV by β-caryophyllene, and group III by β-pinene. The abundance of α-humulene showed small variations; while β-caryophyllene showed larger variations that contributed to the population variability. This is the first report on the chemical composition analysis of volatile compounds in V. curassavica using the HS-GC-MS technique.

Abstract In 2019, an oil spill of unprecedented dimensions and unknown source reached the Brazilian coast. Such incident, which occurred somewhere in the ocean and was detected only when the first oil patches reached the beaches in the northeastern region, is recognized as one of the most serious oil spills in the country. From the chromatographic analysis of the oily residues using n-alkanes, polycyclic aromatic hydrocarbons (PAH), and oil biomarkers, it was possible to characterize their coverage. The results confirmed that an oil of the same specification reached a length of coastline higher than 3,000 kilometers. However, were also found oily residues that did not match with the product involved in that incident, evidencing the occurrence of different discharges. This study documents the extension of the affected coastline during the incident and assesses the possible origin of such different oils from their geochemical characteristics by selecting 21 samples from more than 300 samples previously collected and analyzed during the response actions. The unexpected occurrence of these residues suggest chronic events. The results highlighted that unrelated oily residues were found even in a region far from the coast, indicating that discharges of oil in the open sea occur more regularly than initially expected.

RESUMO Desde o grego Aellus Galenum (129 d.C. - c.200/c.216), a vertigem era considerada um problema atribuído a um distúrbio cerebral, diagnosticado como a manifestação de uma ‘congestão cerebral apoplectiforme’. Em meados do século 19, o francês Prosper Menière mudou esse conceito, colocando a origem desse sintoma na orelha interna. O principal objetivo desta nota histórica é ressaltar quem foi Menière, seu trabalho e alguns aspectos da doença que leva seu nome.
ABSTRACT Since the Greek Aellus Galenum (129 AD - c.200/c.216), vertigo was considered a problem attributed to a cerebral disorder, diagnosed as the manifestation of apoplectiform cerebral congestion. In the mid-19th century, the Frenchman Prosper Menière changed this concept by placing the origin of this symptom in the inner ear. The main objective of this historical note is to highlight who Menière was, his work, and some aspects of the disease that bears his name.

Tacrolimus (TAC), a calcineurin inhibitor, and everolimus (EVL), an mTOR inhibitor, have been used as immunosuppressive (ISS) drugs in post-kidney transplantation therapy. The objective of this study was to compare the efficacy of EVL vs TAC in the ISS maintenance triple therapy. Ninety-seven kidney transplant patients, who received triple maintenance therapy with TAC, mycophenolate mofetil (MMF), and methyl prednisone (PRED), were evaluated. After four months of post-kidney transplant therapy, 30 patients enrolled in a randomized controlled clinical trial, in which 16 patients received TAC+MMF+PRED (cohort 1), and 14 patients switched to EVL+MMF+PRED (cohort 2). The patients were followed-up for 36 months. Two patients from cohort 1 lost their grafts after one year due to non-adherence. Two patients from cohort 2 had intolerance to mTOR inhibitors and were switched back to TAC from EVL. One case (6.25%) in cohort 1 and three cases (21.43%) in cohort 2 of acute T-cell-mediated rejection was observed. Antibody-mediated acute rejection (ABMAR) was observed in four patients (25.0%) in cohort 1, and antibody-mediated chronic rejection (ABMCR) was observed in two patients (12.50%). One patient from cohort 2 lost the graft after 15 months due to polyomavirus infection. The graft survival rate was 87.50% in cohort 1 and 92.86% in cohort 2. This clinical trial showed that the EVL+MMF+PRED triple maintenance therapy was efficacious compared with TAC during 32 months of follow-up. However, further studies are needed to confirm the efficacy of this regimen for long-term graft survival.

Abstract Essential oils (EOs) are a promising alternative for food preservation and can be used instead of synthetic antimicrobial compounds such as sanitizers, as long as they are efficient and safe. In view of this possibility of use, Lippia alba (Mill) (LAEO) and Cymbopogon citratus D.C. Stapf. (CCEO) essential oils were evaluated as natural antimicrobials and applied into coriander for its biocontrol. The EOs were extracted and their physical properties, total phenolics, cytotoxicity to Artemia salina L. and antimicrobial potential in vitro and on natural coriander microbiota were determined. The EOs had a LD50 (median lethal dose - checked), are considered biologically active. MIC (Minimum Inhibitory Concentration) varied from 1.25 to 5.00 μL/ mL and from 0.62 to 5.00 μL/ mL for LAEO and CCEO, respectively, on standard strains of Staphylococcus aureus, Salmonella Thyphimurium, Salmonella Enteritidis, Escherichia coli and Listeria monocytogenes. The lowest MIC values for LAEO and CCEO were selected for application in coriander. EOs reduced the pathogenic microbial load in the coriander revealing its potential as a natural sanitizer, and thus demonstrating superior or equivalent efficacy to commercial sanitizer. By correlating the cytotoxic and antimicrobial results obtained, we have shown that these EOs present potential for application in foods.

RESUMO Objetivou-se avaliar três períodos de adaptação, cinco, 10 e 15 dias, a dietas com baixa ou alta fibra sobre a digestibilidade e características fecais. Foram utilizadas duas dietas, uma contendo 0% de casca de soja (0%CS) e outra com 15% de casca de soja (15%CS), fornecidas a 12 cães adultos. Ao final de cada período, houve coleta total de fezes para avaliação dos coeficientes de digestibilidade aparente (CDA), energia metabolizável (EM) e características fecais. Além disso, foi avaliada a palatabilidade das dietas. Como resultado, não houve efeito do período de adaptação sobre a digestibilidade das dietas (P>0,05). A dieta 15%CS apresentou menor CDA da matéria seca (MS) e EM, em relação à dieta 0%CS (P<0,05). A consistência fecal dos cães não diferiu entre as dietas e os períodos (P>0,05). Houve redução no pH e na amônia fecal dos cães alimentados com a dieta 15%CS (P<0,05), após 10 dias de alimentação. Não houve diferença na palatabilidade das dietas (P>0,05). Períodos de adaptação à dieta superiores a cinco dias não alteram a digestibilidade e a maioria das características fecais de cães, exceto a amônia fecal. A inclusão de 15%CS na dieta reduz a digestibilidade da MS e a EM, bem como o pH e a amônia fecal.
ABSTRACT This study aimed to evaluate three periods of adaptation, 5, 10 and 15 days, to diets with low or high fiber on digestibility and fecal characteristics. Two diets were used, one containing 0% (0% SH) and one containing 15% soybean hulls (15% SH). Diets were provided to 12 adult dogs. At the end of each period there was total collection of feces to evaluate the apparent digestibility coefficients (ADC), metabolizable energy (ME) and fecal characteristics. We also evaluated diet palatability. There was no effect of the adaptation period on digestibility of diets (P> 0.05). The 15% SH diet reduced ADC of dry matter (DM) and ME, compared to the 0% SH diet (P< 0.05). Fecal consistency of the dogs did not differ among diets and periods (P> 0.05). There was a decrease in fecal pH and ammonia in dogs fed the diet with 15% SH (P< 0.05) after 10 days of feeding (P< 0.05). There was no difference in diet palatability (P> 0.05). Diet adaptation longer than 5 days did not alter the digestibility and most fecal characteristics of dogs, except for fecal ammonia. The inclusion of 15% SH in diet reduces DM digestibility and fecal pH and ammonia in dogs.

RESUMO: A pelve é considerada um complexo osteoligamentoso, classificada como dolicopélvica em ruminantes. Prejuízos ligados à incompatibilidade canal pélvico/tamanho fetal relacionam-se diretamente à anatomia e disposição pélvica. A característica de área pélvica apresenta herdabilidade variando de moderada a alta, indicando sua importância na seleção animal. A pelvimetria inclui formas direta e indireta. Neste estudo utilizaram-se vinte e seis vacas multíparas, da raça Nelore, agrupadas de acordo com o estágio reprodutivo, cíclico e em início de estágio puerperal (até 30 dias pós-parto). Através deste, objetivou-se evidenciar a relação das medidas pélvicas internas e externas nos diferentes períodos reprodutivos e coletar obter dados referentes a utilização da área interna do hexágono no estudo pelvimétrico dessa espécie em estágio cíclico ou puerperal. Para tanto, realizou-se, a pelvimetria direta e indireta. Os resultados obtidos, pela análise descritiva, foram maiores para animais em início de estágio puerperal. Por meio da correlação de Pearson podem-se observar fortes correlações entre mensurações pélvicas internas e externas, também entre os grupos propostos, e forte correlação entre elipse pélvica e área interna do hexágono. Pelo teste Tukey diferenças significativas tanto em medidas internas e externas puderam ser demonstradas. Conclui-se que as condições anatômicas da pelve variam de acordo com o estágio reprodutivo do animal, que aferição da área pélvica utilizando a formula proposta para área do hexágono interno é relevante pois foi possível comprovar a diferenças estatísticas de áreas nas fases cíclica e puerperal.
ABSTRACT: Pelvis is an osteoligamentous complex, which is classified as dolichopellic in ruminants. Impairments linked to incompatibility of pelvic canal and fetal size is directly related to pelvic anatomy and disposition. Heritability of pelvic area characteristics varies from moderate to high, demonstrating its importance for animal selection. Pelvimetry can be performed through direct and indirect methods that were accessed in this study aiming to establish a correlation between internal and external pelvic dimensions in multiparous Nellore cows (26 animals) at cycling and early puerperal (up to 30 days postpartum) reproductive stages. Pelvic dimensions measured by descriptive analysis were higher at early puerperal stage. Strong Pearson’s correlation was determined between internal and external pelvic dimensions, between reproductive stages, and between pelvic girdle area and internal pelvic area. Significant Tukey’s test differences between animals in internal and external dimensions were also found. According to the results, the pelvic anatomy of Nellore cows varies according to their reproductive stage. We detach that and provide data regarding the use of internal pelvic area for animal selection studies on this breed is determined and should be measured using the proposed formula, since it can confirm statistical differences in the areas of pelvic components between animals in the cycling and early puerperal stages.

RESUMO Objetivou-se avaliar as características de carcaça e carne de novilhos Aberdeen Angus castrados cirurgicamente em duas idades ou imunocastrados com dois protocolos. Foram utilizados 48 bezerros, monitorados a partir do nascimento e desmamados, com idade e peso médio inicial de seis meses e de 160±16,54kg, respectivamente. Os animais foram distribuídos aleatoriamente nos seguintes tratamentos: castração cirúrgica ao nascer; castração cirúrgica ao desmame; imunocastração com três doses da vacina Bopriva® e imunocastração com quatro doses da vacina Bopriva®. O delineamento experimental utilizado foi o inteiramente ao acaso. Novilhos imunocastrados com três doses apresentaram maior quebra ao resfriamento e menor espessura de gordura ajustada para 100kg de carcaça fria que castrados cirurgicamente ao nascer (P<0,05). A imunocastração com três doses proporcionou incremento na participação de músculo, em relação às castrações cirúrgicas, mas reduziu a gordura em relação à castração cirúrgica ao nascimento (P<0,05). A relação músculo:osso foi superior nos imunocastrados com três doses em relação a castrados cirurgicamente no desmame (P<0,05). Apesar de variações na participação tecidual na carcaça, a castração imunológica mostrou-se viável em substituição à castração cirúrgica, não alterando os padrões qualitativos da carne.
ABSTRACT The objective of this study was to evaluate the carcass and meat characteristics of Aberdeen Angus steers surgically castrated at two ages or immunocastrated with two protocols. Forty-eight calves we used, monitored from birth and weaned, with age and initial mean weight of six months and 160±16.54kg, respectively. The animals were randomly assigned to the following treatments: surgical castration at birth; surgical castration at weaning; immunocastration with three doses of the Bopriva ® vaccine and immunocastration with four doses of the Bopriva ® vaccine. The experimental design was completely randomized. Immunocastrated steers with three doses had a greater cooling break and lower fat thickness adjusted for 100kg of cold carcass than surgically castrated at birth (P< 0.05). Immunocastration with three doses provided an increase in muscle participation in relation to surgical castration but reduced fat in relation to surgical castration at birth (P< 0.05). The muscle:bone ratio was higher in the immunocastrated with three doses compared to surgically castrated at weaning (P< 0.05). Despite variations in tissue involvement in the carcass, the immunological castration proved to be viable to replace surgical castration, not changing the quality of the meat standards.

Carassius auratus is a teleost fish that has been largely used in behavioral studies. However, little is known about potential environmental influences on its performance of learning and memory tasks. Here, we investigated this question in C. auratus, and searched for potential correlation between exercise and visuospatial enrichment with the total number of telencephalic glia and neurons. To that end, males and females were housed for 183 days in either an enriched (EE) or impoverished environment (IE) aquarium. EE contained toys, natural plants, and a 12-hour/day water stream for voluntary exercise, whereas the IE had none of the above. A third plus-maze aquarium was used for spatial and object recognition tests. Different visual clues in 2 of its 4 arms were used to guide fish to reach the criteria to complete the task. The test consisted of 30 sessions and was concluded when each animal performed three consecutive correct choices or seven alternated, each ten trials. Learning rates revealed significant differences between EE and IE fish. The optical fractionator was used to estimate the total number of telencephalic cells that were stained with cresyl violet. On average, the total number of cells in the subjects from EE was higher than those from subjects maintained in IE (P=0.0202). We suggest that environmental enrichment significantly influenced goldfish spatial learning and memory abilities, and this may be associated with an increase in the total number of telencephalic cells.
