Abstract Despite the great diversity, economic and environmental importance of limnic mollusks, the group is still little investigated in the Brazilian semiarid region, especially in the state of Piauí. Thus, this work aims to gather information on the diversity of limnic mollusks in the Brazilian Northeast and the semiarid region, including new records for the state of Piauí, northeastern Brazil. For this, collections in the urban perimeter of the Itaim and Guaribas Rivers, municipalities of Itainópolis, and Picos, respectively, between October 2017 and September 2019. Besides, a literature review was conducted on studies of malacofauna in the Northeast and the Brazilian semiarid region. A total of 11 species from the classes Gastropoda and Bivalvia were collected on the rivers of Piauí, being the first record of Uncancylus concentricus for the Northeast region. For lotic environments in the state of Piauí, Drepanotrema schubarti, Pomacea canaliculata, Pisidium dorbignyi and Stenophysa marmorata were registered for the first time. Then, it was possible to verify that the Northeast of Brazil has 71 species registered, of which 34 occur in the semiarid. The diversity of species surveyed and the first record of the occurrence of several of them for the semiarid region demonstrate the importance of expanding studies involving this group to other areas. The present study is the first to gather and increase the information available on the fauna of limnic mollusks for the Northeast and Brazilian semiarid regions. The information gathered here may contribute to future research and to the species conservation and the environments they occupy, especially considering the presence of non- native and vector species.

Abstract This study evaluated the ability of resistance training (RT) of moderate intensity to promote vascular changes in insulin-induced vasodilation in healthy animals. Wistar rats were divided into two groups: control (CON) and trained (eight weeks of training, performing 3 sets with 10 repetitions at 60% of maximum intensity). Forty-eight hours after the last session of the RT, the animals were sacrificed and vascular reactivity to insulin in the absence and presence of LY294002 (phosphatidylinositol 3-kinase inhibitors (PI3K), L-NAME (nitric oxide synthase (NOS) inhibitors) and BQ123 (endothelin A antagonist (ET-A) receptor). In addition, phenylephrine (Phe)-induced vasoconstriction in the absence and presence of L-NAME was also evaluated. The RT group showed greater vasodilation in maximal response compared to the CON group. After PI3K inhibition, vasodilation was reduced in both groups. However, when the NOS participation was evaluated, the RT group showed contraction in relation to the CON group, which was abolished by BQ123. In addition, the RT group had an increase in nitrite levels compared to the CON group. When the Phe response was evaluated, there was a reduction in tension in the RT group compared to the CON group. The results suggest that RT improves vascular reactivity.

Abstract This study evaluated whether resistance training (RT) could prevent glucocorticoid-induced vascular changes. Wistar rats were divided into groups: control (CO), dexamethasone (DEX), and Dexamethasone+RT (DEX+RT). On the eighth week, dexamethasone was administered in the DEX and DEX+RT groups. Thereafter, the animals were sacrificed and blood samples were used to assess the lipid profile, glucose and insulin. Vascular reactivity to insulin and phenylephrine (Phe) were evaluated. The DEX+RT group presented an improvement in the lipid profile, fasting glucose, and insulin levels compared to the DEX group. In addition, vasodilation was reduced in the DEX group compared to the CO group, and was increased in the DEX+RT group. After inhibition of phosphatidylinositol 3-kinase, DEX group showed contraction, in which it was in the DEX + RT group. When nitric oxide synthase (NOS) participation was evaluated, the DEX group presented a contraction compared to the CO group, with no contractile effect in the DEX+RT group. Moreover, vasoconstriction caused by NOS inhibition was abolished by BQ123 (endothelin receptor antagonist). In respect Phe response, there was an increase in tension in the DEX group compared to the CO group, being reduced in the DEX+RT group. The results suggest that RT prevented damage to vascular reactivity.

Abstract: En | Text: En | PDF: En

The objective was to evaluate increasing levels of dried brewers' grains (DBG) in feed for broiler chickens from 1 to 21 days old and their effect on performance, blood parameters, intestinal morphometry, carcass characteristics and meat quality. The design was completely randomized with six treatments, which consisted of various levels of DBG inclusion, namely 0 (no inclusion), 20, 40, 60, 80, and 100 g/kg with seven replications and 17 animals per experimental unit, totalling 714 male broilers. Performance parameters, blood biochemical profile, morphology of the intestinal epithelium (duodenum), and carcass yield and composition were evaluated. Feed intake was not changed by DBG inclusion levels. Nor were weight gain and feed conversion ratio. Serum cholesterol levels were not influenced, and there were no effects on triglyceride, uric acid and creatinine levels. Enzyme aspartate aminotransferase showed a quadratic effect, as did alanine aminotransferase, with higher values at 79.5 and 63.9 g/kg DBG inclusion, respectively. No changes in carcass yield and relative organ weight were observed. The composition of the carcass in ether extract showed a quadratic effect, as fat deposition rate, with lowest values at 62.8 and 62.4 g/kg of DBG inclusion levels, respectively. Crude protein levels in carcass reduced linearly, as did fat deposition rate. The parameters of intestinal morphology and meat quality were not changed. Dried brewers' grains can be included in broiler diet from 1 to 21 days at levels up to 100 g/kg without influencing the metabolic parameters and broiler performance.

ABSTRACT Objective: To evaluate the prevalence and risk factors associated with progression to recurrent wheezing in preterm infants. Methods: The cross-sectional study was carried out in 2014 and 2015 and analyzed preterm infants born between 2011 and 2012. The search for these children was performed in a university maternity hospital and a Special Immunobiological Reference Center. The evaluation was performed through a questionnaire applied during a telephone interview. Results: The study included 445 children aged 39 (18-54) months. In the univariate analysis, the risk factors with the greatest chance of recurrent wheezing were birth weight <1000 g, gestational age <28 weeks, living with two or more siblings, food allergy, and atopic dermatitis in the child, as well as food allergy and asthma in the parents. In the multivariate analysis, there was a significant association between recurrent wheezing and gestational age at birth <28 weeks, food allergy and atopic dermatitis in the child, and living with two or more children. Of the 445 analyzed subjects, 194 received passive immunization against the respiratory syncytial virus, and 251 preterm infants were not immunized. There was a difference between the gestational age of these subgroups (p < 0.001). The overall prevalence of recurrent wheezing was 27.4% (95% CI: 23.42-31.70), whereas in the children who received passive immunization it was 36.1% (95% CI: 29.55-43.03). Conclusions: Personal history of atopy, lower gestational age, and living with two or more children had a significant association with recurrent wheezing. Children with lower gestational age who received passive immunization against the respiratory syncytial virus had a higher prevalence of recurrent wheezing than the group with higher gestational age.

RESUMO Objetivo: Avaliar a prevalência e os fatores de risco associados à evolução para sibilância recorrente em prematuros. Métodos: O estudo transversal foi feito em 2014 e 2015 e analisou crianças prematuras nascidas entre 2011 e 2012. A busca dessas crianças foi feita em maternidade de hospital universitário e em um Centro de Referência para Imunobiológicos Especiais. A avaliação foi feita por questionário dirigido em entrevista telefônica. Resultados: O estudo incluiu 445 crianças com 39 (18-54) meses de vida. Na análise univariada, os fatores de risco com maior chance de sibilância recorrente foram peso de nascimento menor do que 1.000 g, idade gestacional menor do que 28 semanas, convivência com dois ou mais irmãos, alergia alimentar e dermatite atópica na criança e alergia alimentar e asma nos pais. Na análise multivariada houve associação significativa entre sibilância recorrente e idade gestacional ao nascer menor do que 28 semanas, alergia alimentar e dermatite atópica na criança e a convivência com duas ou mais crianças. Dos 445 sujeitos analisados, 194 receberam imunização passiva contra vírus sincicial respiratório e 251 eram prematuros não imunizados. Houve diferença entre a idade gestacional desses subgrupos (p < 0,001). A prevalência geral de sibilância recorrente foi 27,4% (IC 95%: 23,42-31,70) e nas crianças que receberam a imunização passiva foi 36,1% (IC 95%: 29,55-43,03). Conclusões: História pessoal de atopia, menor idade gestacional e convivência com duas ou mais crianças apresentaram associação significativa com sibilância recorrente. As crianças com menor idade gestacional, que receberam a imunização passiva contra o vírus sincicial respiratório, apresentaram maior prevalência de sibilância recorrente que o grupo de maior idade gestacional.

Abstract: En | Text: En | PDF: En

ABSTRACT Orofacial pain is related to tissues of the head, face, neck and all the intraoral structures; it is rather debilitating to the patient and also difficult to treat. There are relatively few studies dedicated to the use of natural products to alleviate orofacial pain in preclinical experiment models (performed in experimental animals which provide support for clinical trials). Main objectives of the present systematic review summarize the studies on natural products assessed in animal models for orofacial pain seeking to give evidence to future development of new pharmaceutical products to manage the orofacial pain. Our review includes a thorough search of literature using the terms of orofacial pain, facial pain, medicinal plants and natural products. This search was performed using to retrieve English language articles in Medline-PubMed, Scopus and Web of Science. A total of eighteen studies were included in our survey for the inclusion criteria. Firstly, this review identified 210 citations from electronic search, after removal of duplicates and screening for relevant titles and abstracts, a total of eighteen articles were selected to the inclusion criteria established. Our findings suggest that natural products can be a promising or a trump tool for the development of new drugs to treat orofacial pain conditions, but the researchers that deal with experimental preclinical trials of new drugs (including natural products or synthetic drugs) for orofacial pain conditions urgently need to show translational evidence (with clinical approach) of these compounds.

Abstract: En | Text: En | PDF: En

Estrogen deficiency and hypertension are considered major risk factors for the development of coronary heart disease. On the other hand, exercise training is considered an effective form to prevent and treat cardiovascular diseases. However, the effects of swimming training (SW) on coronary vascular reactivity in female ovariectomized hypertensive rats are not known. We aimed to evaluate the effects of SW on endothelium-dependent coronary vasodilation in ovariectomized hypertensive rats. Three-month old spontaneously hypertensive rats (SHR, n=50) were divided into four groups: sham (SH), sham plus swimming training (SSW), ovariectomized (OVX), and ovariectomized plus swimming training (OSW). The SW protocol (5 times/week, 60 min/day) was conducted for 8 weeks. The vasodilatory response was measured in isolated hearts in the absence and presence of a nitric oxide synthase inhibitor (L-NAME, 100 µM). Cardiac oxidative stress was evaluated in situ by dihydroethidium fluorescence, while the expression of antioxidant enzymes (SOD-2 and catalase) and their activities were assessed by western blotting and spectrophotometry, respectively. Vasodilation in SHR was significantly reduced by OVX, even in the presence of L-NAME, in conjunction with an increased oxidative stress. These effects were prevented by SW, and were associated with a decrease in oxidative stress. Superoxide dismutase 2 (SOD-2) and catalase expression increased only in the OSW group. However, no significant difference was found in the activity of these enzymes. In conclusion, SW prevented the endothelial dysfunction in the coronary bed of ovariectomized SHR associated with an increase in the expression of antioxidant enzymes, and therefore may prevent coronary heart disease in hypertensive postmenopausal women.

ABSTRACT The population of wild animals is regulated by many biotic and abiotic factors, and parasites are a biotic factor that affects the dynamic and density of host populations. From 2002 to 2014, 62 wild animals from the biomes Pantanal, Amazon, and "Cerrado" (or Savanna), which died in attendance in the veterinary hospital or have been road-killed, underwent necropsy for parasitological examination. Overall, 36 species of parasites were identified from 24 host species. Among the parasites, the most prevalent order was Oxyurida (29.1%), followed by Strongylida (20.9%), Spirurida (19.4%), Ascaridida (16.2%), Pentastomida (3.2%), Echinostomida (3.2%), Gygantorhynchia (3.2%), Rhabditida (1.6%), Plagiorchiida (1.6%), and Monilimorfida (1.6%), especially nematodes, which have more biotic potential and is more easily adapted to the environment than other classes. The occurrence of endoparasites was observed more frequently in endothermic than ectothermic animals, and herein is reported eleven new host occurrences for endoparasites in wild animals. The study has contributed to the knowledge on the biodiversity of parasites in wild animals from three biomes in central-western Brazil.

RESUMO Populações de animais selvagens são reguladas por diversos fatores bióticos e abióticos, e parasitas são um fator biótico que afetam a dinâmica e a densidade de populações. De 2002 até 2014, 62 animais silvestres provenientes dos biomas Pantanal, Amazônia e Cerrado, que vieram a óbito no atendimento do hospital veterinário ou foram encontrados atropelados em rodovias, foram submetidos à necropsia parasitológica. Ao todo 36 espécies de parasitas foram identificadas em 24 espécies de hospedeiros. Entre os parasitas, a ordem mais prevalente foi Oxyurida (29,1%), seguida por Strongylida (20,9%), Spirurida (19,4%), Ascaridida (16,2%), Pentastomida (3,2%), Echinostomida (3,2%), Gygantorhynchia (3,2%), Rhabditida (1,6%), Plagiorchiida (1,6%) e Monilimorfida (1,6%), destacando-se os nematódeos, por seu maior potencial biótico e facilidade de adaptação ao meio do que as demais classes. A maior ocorrência de endoparasitas foi observada em animais endotérmicos que ectotérmicos, e este estudo registra onze novas ocorrências de hospedeiros para endoparasitas de animais selvagens. O estudo contribui para o conhecimento da biodiversidade de parasitas em animais silvestres dos três biomas do Centro-Oeste do Brasil.

O presente trabalho teve como objetivo avaliar a biocompatibilidade e a osseointegração de compósitos de hidroxiapatita (HA), policaprolactona (PCL) e alendronato (ALN) em defeitos ósseos produzidos no olécrano de coelhos. Trinta e seis coelhos foram distribuídos em quatro grupos, recebendo como tratamento: (1) compósito de HA (49,5%), PCL (49,5%) e ALN (1%); (2) HA (50%) e PCL (50%); (3) PCL (100%); e (4) solução salina 0,9%. As amostras para análise histológica foram coletadas de três animais de cada grupo aos oito, 45 e 90 dias de pós-operatório. No oitavo dia, as bordas do defeito ainda eram identificáveis em todos os grupos. Tecido ósseo novo era formado em contato com o biomaterial apenas nas formulações que incluíam HA. Essas características continuaram evidentes nos outros momentos analisados, embora o defeito estivesse preenchido pelo tecido regenerado. A presença dos biomateriais foi verificada nos três momentos em todos os grupos. Não houve evidências de reação indesejável ao biomaterial. As análises histológicas e histomorfométricas mostraram que os biomateriais são biocompatíveis e aqueles contendo a hidroxiapatita favoreceram a formação óssea no início do processo de regeneração, embora o alendronato não tenha apresentado qualquer efeito.

ABSTRACT Thirty-six dogs undergoing elective ovariohysterectomy surgery were randomly distributed into 3 groups of 12 animals each. In the first group, dense-dispersed electroacupuncture was performed with a frequency of 3-200 Hz in SP4, ST44, KID3 points and 1.5mL of saline was given intramuscularly (GEA group). For the second group, dense-dispersed electroacupuncture was performed with a frequency of 3-200 Hz in SP6, ST36, GB34 points and 1.5mL of saline given intramuscularly (GEB group). In the third group acupuncture was performed in 3 false points being the electroacupuncture device attached to the needles but not connected, and morphine was also administered at a dose of 0.5mg/kg diluted in saline so that the total volume was 1.5mL intramuscularly (GF group). Cardiovascular and respiratory parameters were evaluated during the pre and perioperative period. The evaluation of pain and postoperative sedation was performed for 12 hours and analgesic supplementation was performed whenever the pain score reached values above or equal to 9 points (in a total of 27) in accordance with the Scale of Pain of the University of Melbourne (EDUM). The GEB group had stable blood pressure and lower Etiso value as well as less need for additional analgesia postoperatively. The GEA group showed the highest values of Etiso and showed the greatest need for additional analgesia in the immediate postoperative period (at the moment of extubation). The GF group required more supplementary analgesia postoperatively and showed higher sedation scores up to 4 hours after surgery. The KID3, ST44 and SP4 acupoints used in electroacupuncture with frequency 3-200 Hz are not able to promote satisfactory antinociceptive action in the perioperative period. Postoperative analgesic effect, promoted by electrical stimulation in acupoints KID3, ST44 and SP4, is inferior to that provided by acupoints ST36, SP6 and GB34 and superior to that obtained with morphine.

Objetivou-se com este estudo avaliar o efeito analgésico trans e pós-operatório da eletroacupuntura em onda denso-dispersa e frequências 3 e 200Hz, nos pontos E44, R3 e BP4, compará-lo com a analgesia promovida pelos pontos BP6, E36 e VB 34, e pela morfina, em cadelas submetidas à ovariosalpingohisterectomia (OSH). Teve-se como hipótese que a eletroacupuntura nos pontos E44, R3 e BP4 resultaria em controle da dor trans e pós-operatória melhor ou igual àquele promovido pela eletroacupuntura nos pontos BP6, E36 e VB34 e pela morfina. Trinta e seis cadelas submetidas à cirurgia eletiva de OSH foram distribuídas em blocos ao acaso em três grupos com 12 animais. Em dois grupos foi realizada eletroacupuntura denso-dispersa, com frequência de 3 e 200Hz, sendo que, no primeiro grupo (GEA), foram estimulados os pontos BP4, E44, R3 e, no segundo grupo (GEB), os pontos BP6, E36, VB34. Nesses dois grupos, foram administrados 1,5mL de solução fisiológica por via IM. No terceiro grupo (GF), foi realizada acupuntura em três pontos falsos e o aparelho de eletroacupuntura foi acoplado, mas não foi ligado, e administrou-se morfina na dose de 0,5mg/kg, diluída em solução fisiológica de modo que o volume total foi de 1,5mL por via IM. Foram avaliados os parâmetros cardiovasculares e respiratórios durante o período pré e transoperatório. A avaliação de dor pós-operatória foi realizada durante 12 horas, e a analgesia suplementar com morfina foi realizada quando o escore de dor alcançou valores iguais ou superiores a nove pontos (total de 27) de acordo com a "Escala de dor da Universidade de Melbourne" (EDUM). O grupo GEB apresentou pressão arterial estável, menor variação da Etiso e menor requerimento analgésico no pós-operatório. Nos grupos GEA e GF houve aumento da Etiso e da pressão arterial nos momentos de maior manipulação cirúrgica. Os maiores escores de dor foram obtidos em MP0 (momento da extubação) no GEA (8) e em MP1(1h após a extubação) no GF (9). O GF apresentou o maior requerimento analgésico no pós-operatório e foram realizados 17 resgates em 6 animais. Os acupontos R3, E44 e BP4, utilizados na eletroacupuntura com a frequência de 3 e 200Hz, não são capazes de promover ação antinociceptiva satisfatória no período transoperatório. O efeito analgésico pós-operatório promovido pela eletroestimulação nos acupontos R3, E44 e BP4 é inferior ao proporcionado pelos acupontos E36, BP6 e VB34 e superior ao obtido com a morfina.

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.

The present study reports the isolation of Salmonellaenterica in organs of free-living domestic pigeons. In the clinic examination, the presence of feces in the peri-cloacal and abdominal regions were observed, as well as symptoms such as cachexy, incoordination and opisthotonos. Before any therapeutic protocol was applied the bird died and a necropsy was then performed for the removal of spleen, liver, kidney and intestine for bacteriological examination and antibiotic sensitivity test. Salmonella enterica subsp.enterica (O:4,5:i-) and Salmonellaenterica subsp. enterica serovar Typhimurium were isolated from the liver and intestine and the sensitivity test demonstrated that these strains are sensitive to several antibiotics.

O presente trabalho relata o isolamento de Salmonella enterica em órgãos de um pombo doméstico de vida livre. No exame clínico foi observada a presença de fezes pericloacal na região ventral, caquexia, incoordenação motora e opistótono. Antes de iniciar um protocolo terapêutico, a ave foi a óbito, e, em seguida, foi realizada uma necropsia para remoção do baço, fígado, rim e intestino para exame bacteriológico e teste de sensibilidade a antibióticos. Foi isolado Salmonella enterica subsp. enterica (O:4,5:i-) e Salmonella enterica subsp. enterica sorovar Typhimurium do fígado e intestino, e o teste de sensibilidade demonstrou que essas cepas são sensíveis a vários antimicrobianos.

Abstract: En | Text: En | PDF: En

The appearance of resistant bacteria was found to reduce the efficiency of antimicrobial therapies with the current antibiotics, thereby increasing the need for more efficient drugs for the treatment of infections. Several studies have demonstrated an increase in antimicrobial activity following the interaction of several compounds with metal ions. The present study used a methodology adapted for antimicrobial bioassays using plant extracts, in compliance with the standards of the Clinical and Laboratory Standards Institute against Gram-positive and Gram-negative bacteria. The results obtained were considered appropriate for determining MIC, MBC as for performing antimicrobial sensitivity testing with good efficiency and reproducibility. The bacteriaPseudomonas fluorescens exhibited high sensitivity to the tested compounds, being efficient to evaluate the antibacterial activity. The bioassays with the metal complexes of flavonoid quercetin and Ga(III) ions, and synthetic ligand H2bbppd and Cu(II) ions showed a greater inhibitory effect than their individual ligands, thus, the addition indicated an increase in the antimicrobial activity after the coordination. Both metal complexes exhibit good antimicrobial performances, such as low minimum inhibitory concentration (MIC ≤ 250 µg/ml), bactericidal effect and a broad activity spectrum, which qualify these compounds as suitable candidates to the next step of drugs fabrication. Nevertheless, further studies on the mechanism of growth inhibition and toxicity are needed, in order to evaluate the potential of therapeutic application.
