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 Lesões de nervos periféricos levam a perda funcional elevada no tecido muscular. Assim, muitas pesquisas têm investigado técnicas cirúrgicas, como neurorrafias, e recursos terapêuticos, como eletroestimulação, para melhorar a funcionalidade de um músculo reinervado após lesão periférica. Este estudo tem como objetivo investigar os efeitos da eletroestimulação com corrente russa (2.500Hz, 4ms, 10 seg. de contração por 20 seg. de relaxamento, modulação de 10Hz e 100 Hz) na recuperação funcional após secção e neurorrafia término-lateral do coto distal do nervo fibular comum à face lateral do nervo tibial em ratos. Foram utilizados 25 ratos Wistar, machos, com 80 dias de vida, fornecidos pelo Biotério Central da Universidade Sagrado Coração (Bauru, SP, Brasil). Os animais foram divididos aleatoriamente em cinco grupos: grupo-controle Inicial (GCI), grupo-controle final (GCF), grupo experimental não tratado (GENT), grupo neurorrafia término-lateral com estimulação russa (GNTLER) e grupo-controle desnervado (GCD). A corrente russa foi iniciada cinco dias após neurorrafia e aplicada no músculo tibial cranial do GNTLER, 3 vezes por semana, totalizando 36 sessões. A estimulação elétrica foi eficaz para aumentar a amplitude e diminuir a latência do músculo reinervado, além de aumentar a força muscular em comparação ao GCD. Diante disso, conclui-se que a eletroestimulação de média frequência (corrente russa) foi eficiente na recuperação funcional do músculo tibial cranial após neurorrafia término-lateral do nervo fibular comum.
ABSTRACT Peripheral nerve injury leads to a high functional loss of muscle tissue. Thus, many studies have investigated surgical techniques, such as neurorraphies, and therapeutic resources, such as electrical stimulation, to improve the functionality of reinnervated muscle after peripheral injury. This study aims to investigate the effects of electrical stimulation with Russian Current (2,500Hz, 4ms, 10:20 sec contraction/relaxation, modulated at 10Hz and 100Hz) in the functional recovery after section and end-to-side neurorrhaphy of the peroneal nerve distal stump common to the lateral face of the tibial nerve in rats. In this study, 25 male Wistar rats with 80 days of life were used, provided by the Universidade Sagrado Coração (USC), Bauru, SP, Brazil. The animals were randomly divided into five groups: Initial Control Group (ICG), Final Control Group (FCG), Untreated Experimental Group (UEG), End-to-Side Neurorrhaphy with Russian Stimulation Group (ENRSG), and Denervated Control Group (DCG). The Russian Current was started 5 days after neurorrhaphy and applied to the cranial tibial muscle of the ENRSG, 3 times a week, totaling 36 sessions. We observed that the electrical stimulation with Russian Current (ENRSG) was effective to increase amplitude (mV) and to decrease the latency (ms) of the reinnervated muscle, besides increasing the muscle strength when compared with the denervated control group. Therefore, we concluded that the average frequency electrical stimulation (Russian current) was efficient in the functional recovery of the cranial tibial muscle after the end-lateral neurorrhaphy of the common fibular nerve.

De esta manera, en muchos estudios se han investigado técnicas quirúrgicas, como neurorrafias, y recursos terapéuticos, como la electroestimulación, para mejorar la funcionalidad del músculo reinervado tras una lesión periférica. El presente estudio tiene como objetivo investigar los efectos de la electroestimulación con corrente rusa (2.500Hz, 4ms, 10 seg. de contracción por 20 seg. de relajación, modulación de 10Hz y 100Hz) en la recuperación funcional tras la sección y neurorrafia término-lateral del muñón distal del nervio fibular común en la parte lateral del nervio tibial en ratas. Se utilizaron 25 ratas Wistar, machos, con 80 días de vida, proporcionadas por el Biotério Central de la Universidade do Sagrado Coração (Bauru, SP, Brasil). Se dividieron aleatoriamente los animales en cinco grupos: grupo de control inicial (GCI), grupo de control final (GCF), grupo experimental no tratado (GENT), grupo de neurorrafia término-lateral con estimulación rusa (GNTLER) y grupo de control denervado (GCD). La corriente rusa se inició cinco días tras la neurorrafia, siendo que la aplicó al músculo tibial craneal del GNTLER 3 veces a la semana, con un total de 36 sesiones. La estimulación eléctrica se mostró efectiva para aumentar la amplitud y disminuir la latencia del músculo reinervado, además de aumentar la fuerza muscular en comparación con el GCD. Por lo tanto, se concluye que la estimulación eléctrica de frecuencia media (corriente rusa) fue eficaz en la recuperación funcional del músculo tibial craneal tras la neurorrafia término-lateral del nervio fibular común.

Resumen Introducción. Trypanosoma cruzi se ha dividido en seis unidades taxonómicas discretas (Discreet Typing Units, DTU) denominadas TcI, TcII, TcIII, TcIV, TcV y TcVI. Aún se desconocen los factores determinantes de la dinámica de la transmisión vectorial de los genotipos de T. cruzi en las diferentes regiones geográficas de distribución de la enfermedad de Chagas en Perú. Objetivo. Detectar y tipificar las unidades taxonómicas discretas de T. cruzi en las heces de siete especies de triatominos (Panstrongylus chinai, P. geniculatus, P. herreri, Rhodnius robustus, R. pictipes, Triatoma carrioni y T. infestans), capturados en ocho departamentos de diferentes regiones naturales de Perú. Materiales y métodos. Se examinaron 197 insectos para la detección de tripanosomas. Se extrajo el ADN del contenido intestinal de cada insecto y se amplificó mediante reacción en cadena de la polimerasa (PCR) de los genes kDNA, SL-IR, 24Sa rRNA y 18Sa RNA para detectar las DTU de T. cruzi. Resultados. Se detectaron cinco infecciones con T. rangeli y 113 con T. cruzi. De estas últimas, fue posible identificar 95 de TcI (dos en P. chinai, una en P. geniculatus, 68 en P. herreri, cuatro en R. pictipes, siete en R. robustus, una en T. carrioni, y 12 en T. infestans); cinco de TcII (cuatro en P. herreri, una en T. infestans); cuatro de TcIII (tres en P. herreri, una en R. robustus) y cuatro infecciones de TcIV en P. herreri. Conclusión. Este es el primer trabajo de caracterización a gran escala de T. cruzi en el intestino de vectores de importancia epidemiológica en Perú, orientado a generar información básica que permita entender la dinámica de la transmisión vectorial de T. cruzi en esta región del continente.
Abstract Introduction: Trypanosoma cruzi has been divided by international consensus into six discrete typing units (DTU): TcI, TcII, TcIII, TcIV, TcV y TcVI. The factors determining the dynamics of T. cruzi genotypes vector transmission of Chagas’ disease in the different geographical regions of Perú are still unknown. Objective: To detect and type T. cruzi DTUs from the faeces of seven species of triatomines (Panstrongylus chinai, P. geniculatus, P. herreri, Rhodnius robustus, R. pictipes, Triatoma carrioni and T. infestans) captured in eight departments from different natural regions of Perú. Materials and methods: We examined 197 insects for detecting trypanosomes. DNA was extracted from each insect intestinal contents and PCR amplification of kDNA, SL-IR, 24Sa rRNA and 18Sa RNAwas performed for detecting T. cruzi DTUs. Results: Five T. rangeli and 113 T. cruzi infections were detected; 95 of the latter were identified as TcI (two in P. chinai, one in P. geniculatus, 68 in P. herreri, four in R. pictipes, seven in R. robustus, one in T. carrioni, 12 in T. infestans), five as TcII (four in P. herreri, one in T. infestans), four as TcIII (three in P. herreri, one in R. robustus) and four TcIV infections in P. herreri. Conclusions: This is the first study which has attempted a large-scale characterization of T. cruzi found in the intestine of epidemiologically important vectors in Perú, thus providing basic information that will facilitate a better understanding of the dynamics of T. cruzi vector transmission in Perú.

RESUMO As lesões de nervos periféricos ocorrem frequentemente e, de modo geral, causam perda funcional impactando de forma negativa na vida do paciente. O objetivo do estudo foi verificar a eficiência da associação da laserterapia e natação em ratos acometidos por axonotmeses. A amostra foi composta por 50 ratos da linhagem Wistar. Foram divididos em 5 grupos, sendo: grupo controle (GC); grupo controle cirúrgico (GCC); grupo experimental laser (GEL); grupo experimental natação (GEN) e grupo experimental laser associado à natação (GELAN). O nervo foi esmagado em um segmento de 5 mm de comprimento próximo a trifurcação do nervo isquiático, feito com uma pinça durante 60 segundos. Foi utilizado o laser infravermelho AsGa (904 nm) com energia irradiada de 0,4 J na primeira semana, 0,8 J na segunda semana e 1,2 J na terceira e quarta semana. Para avaliação funcional (IFC), os animais foram imobilizados, e a região plantar das patas foram pintadas com tinta de carimbo. Esse procedimento foi repetido duas vezes com cada animal. Foi realizada a morfometria (áreas, diâmetros e espessuras das fibras, axônios e bainha de mielina) dos nervos com mensuração de 220 fibras por animal de cada grupo. Pudemos observar que os grupos GEL e GEN, em todas as variáveis morfométricas estudadas, obtiveram os melhores resultados, quando comparados com os outros grupos (GC, GCC e GELAN), mas não apresentou diferença estatisticamente significante entre eles. Na análise funcional observou-se que o grupo GELAN obteve o melhor resultado quando comparado com os outros grupos (GCC, GEL e GEN) e quando comparados os grupos GEL e GEN entre eles não houve diferença estatisticamente significante. A conclusão foi que os grupos GEL e GEN obtiveram os melhores resultados morfométricos, enquanto o GELAN apresentou o melhor resultado funcional. Portanto, pode-se concluir que a associação destes recursos favoreceu a recuperação funcional desses animais.
ABSTRACT The peripheral nerve injuries occur frequently and generally cause functional loss impacting negatively on patient's life. The objective this study was to verify the efficiency of the combination of laser therapy and swimming in rats affected by axonotmesis. The sample was comprised of 50 Wistar rats and it was divided into 05 groups: Control Group; Surgical Control Group; Laser Experimental Group; Swimming Experimental Group and Laser Experimental combined with Swimming Group. The nerve was crushed into a 5 mm-long segment next to the sciatic nerve trifurcation with a pair of forceps for 60 seconds. The GaAs infrared laser (904nm) was used with energy radiated 0,4J the first week, the second week 0,8J and 1,2J in the third and fourth week. For functional (FCI) evaluation, the animals were immobilized and the plantar region of their paws were painted with ink stamp. The procedure was repeated twice to each animal. The nerve morphometry (areas, diameters and thicknesses of the fibers, axons and myelin sheath) was performed with the measurement of 220 fibers per animal in each group . We can see that the GEL and GEN groups , obtained the best results when compared with the other groups (GC, GCC and GELAN) in all morphometric variables studied, but no statistically significant difference was found between them. In functional analysis, it was observed that the gelan group obtained the best results when compared with the other groups (GCC , GEN and GEL) and when the GEL and GEN groups were compared, there was no statistically significant difference between them. Was conclued the GEL and GEN groups havd the best morphometric results, while the GELAN showed the best functional outcome. Therefore, it can be concluded that the combination of these features favoured the functional recovery of the animals.

Cancer has become a major public health problem worldwide and the number of deaths due to this disease is increasing almost exponentially. In the constant search for new treatments, natural products of plant origin have provided a variety of new compounds to be explored as antitumor agents. Tabernaemontana catharinensis is a medicinal plant that produces alkaloids with expressive antitumor activity, such as heyneanine, coronaridine and voacangine. The aim of present study was firstly to screen the cytotoxic activity of the indole alkaloids heyneanine, coronaridine and voacangine against HeLa (human cervix tumor), 3T3 (normal mouse embryo fibroblasts), Hep-2 (human laryngeal epithelial carcinoma) and B-16 (murine skin) cell lines by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide); and secondly to analyze the apoptotic activity, cell membrane damage and genotoxicity of the compound that showed the best cytotoxic activity against the tumor cell lines tested. Coronaridine was the one that exhibited greater cytotoxic activity in the laryngeal carcinoma cell line Hep-2 (IC50 = 54.47 µg/mL) than the other alkaloids tested (voacangine IC50 = 159.33 µg/mL, and heyneanine IC50 = 689.45 µg/mL). Coronaridine induced apoptosis in cell lines 3T3 and Hep-2, even at high concentrations. The evaluation of genotoxicity by comet assay showed further that coronaridine caused minimal DNA damage in the Hep-2 tumor cell line, and the LDH test showed that it did not affect the plasma membrane. These results suggest that further investigation of coronaridine as an antitumor agent has merit.

OBJECTIVES: This study evaluated plantar thermography sensitivity and specificity in diagnosing diabetic polyneuropathy using cardiac tests (heart rate variability) as a reference standard because autonomic small fibers are affected first by this disease. METHODS: Seventy-nine individuals between the ages of 19 and 79 years old (28 males) were evaluated and divided into three groups: control (n = 37), pre-diabetics (n = 13) and type 2 diabetics (n = 29). The plantar images were recorded at baseline and then minutes after a provocative maneuver (Cold Stress Test) using an infrared camera that is appropriate for clinical use. Two thermographic variables were studied: the thermal recovery index and the interdigital anisothermal technique. Heart rate variability was measured in a seven-test battery that included three spectral indexes (in the frequency domain) and four Ewing tests (the Valsalva maneuver, the orthostatic test, a deep breathing test, and the orthostatic hypotension test). Other classically recommended tests were applied, including electromyography (EMG), Michigan inventory, and a clinical interview that included a neurological physical examination. RESULTS: Among the diabetic patients, the interdigital anisothermal technique alone performed better than the thermal recovery index alone, with a better sensitivity (81.3%) and specificity (46.2%). For the pre-diabetic patients, the three tests performed equally well. None of the control subjects displayed abnormal interdigital anisothermal readouts or thermal recovery indices, which precluded the sensitivity estimation in this sample of subjects. However, the specificity (70.6%) was higher in this group. CONCLUSION: In this study, plantar thermography, which predominately considers the small and autonomic fibers that are commonly associated with a sub-clinical condition, proved useful in diagnosing diabetic neuropathy early. The interdigital anisothermal test, when used alone, performed best.
