title: Five new species of Vernonieae (Asteraceae) from Espírito Santo, Brazil

description: Abstract Espírito Santo is a hotspot of diversity in the Atlantic Forest in Brazil, where five new species of Vernonieae from the genera Cololobus, Lepidaploa, Lessingianthus, Piptocarpha, and Vernonanthura were found, and four of them occur in the municipality of Santa Teresa. These discoveries show that current knowledge on biodiversity in Espírito Santo is incipient, even in sites with decades of biological inventories, such as Santa Teresa. Here, all five species are described with comments about distribution, conservations status, phenology and taxonomic affinities. We also provide illustrations and a distribution map of the new species. According to the criteria of IUCN red list, Cololobus argenteus and Vernonanthura spathulata must be included in endangered (EN) category.

title: New data on the Late Cretaceous lizard Dicothodon bajaensis (Squamata, Borioteiioidea) from Baja California, Mexico reveals an unusual tooth replacement pattern in squamates

description: Abstract Borioteiioids comprise an extinct family of squamates that inhabited the Northern Hemisphere during the Cretaceous and were characterized by varying patterns of tooth replacement and dental morphology. Understanding the evolution of these tooth replacement patterns has, however, been largely hampered by an extremely fragmentary fossil record. Here we present new information on Dicothodon bajaensisfrom the Campanian of Baja California (Mexico), so far known only from isolated teeth and jaw fragments. Among abundant new materials there are ten maxillae and five dentaries belonging to distinct ontogenetic stages. Whereas juveniles display active tooth replacement, older specimens show no evidence of replacement. Dicothodon bajaensis is therefore inferred to have had arrested tooth replacement later in ontogeny. This provides the first evidence of cessation of tooth replacement during late ontogeny in lizards (living or extinct). This replacement type is also an evolutionary intermediate between the typical lizard replacement pattern, observed in some borioteiioids (e.g., Bicuspidon) and the complete absence of tooth replacement since early ontogeny as observed in other borioteiioids (e.g., Polyglyphanodon).

title: Saturniid moths (Lepidoptera: Bombycoidea) from an Atlantic Rain Forest fragment in southeastern Brazil

description: Abstract The light-attracted silk moths (Lepidoptera: Saturniidae) of the Boraceia Biological Station in the municipality of Salesópolis, state of São Paulo, southeastern Brazil have been sampled over more than seven decades (1942-2013). A total of 6,288 individuals (including a gynandromorph) belonging to five subfamilies, 46 genera and 133 species were identified. Hemileucinae was the most abundant and speciesrich subfamily, followed by Ceratocampinae, Arsenurinae, Saturniinae, and Oxyteninae. Hylesia Hübner, Automeris Hübner, and Dirphiopsis Bouvier (Hemileucinae) were the dominant genera in abundance and species richness. Only Automeris illustris (Walker), Gamelia remissoides Lemaire, and Hidripa paranensis (Bouvier) (Hemileucinae) were recorded in all months of sampling. Hylesia metapyrrha (Walker) was the most abundant saturniid species recorded at the station, with 375 specimens, followed by Hylesia oratex Dyar with 265 specimens, Dirphia muscosa Schaus with 261 specimens (all Hemileucinae); Copaxa canella Walker (Saturniinae) with 232 specimens, and Lonomia cf. obliqua Walker (Hemileucinae) with 106 specimens. Fifteen additional species were each represented by more than 100 specimens. The importance of the Boraceia Biological Station to the maintenance of the saturniid moth diversity in the Atlantic Forest is discussed.

title: Hydatidosis, cysticercosis, and tuberculosis rates in bovine slaughtered under state sanitary inspection in Rio Grande do Sul, Brazil

description: ABSTRACT This study sought to evaluate the occurrence of lesions suggestive of hydatidosis, cysticercosis, and tuberculosis in animals slaughtered under sanitary inspection of the Divisão de Inspeção de Produtos de Origem Animal (DIPOA), in the state of Rio Grande do Sul. Condemnation data between the years 2009 and 2017 were obtained from Secretaria da Agricultura Pecuária e Irrigação (SEAPI) and presented according to the administrative regions established by SEAPI. In that period, 7,509,544 cattle were slaughtered and condemnations occurred in all regions of the state at varying levels. The mean condemnation values showed the presence of hydatidosis in 523,399 (6.97%), cysticercosis in 92,277 (1.23%), and tuberculosis in 10,595 (0.14%) cattle carcasses. The mean values of hydatidosis diagnoses were higher in the regions of Alegrete (14.19%), Bagé (19.62%), and Pelotas (17.71%). The regions of Osório (1.86%), Santa Maria (2.10%), and São Luiz Gonzaga (1.83%) had highest rates of cysticercosis condemnations. All regions maintained an average bovine tuberculosis diagnosis rate of less than 1% and Estrela region had the highest index (0.70%). Results showed that the three diseases occurred in all regions of the state, the average prevalence rates in each region are variable, and distribution seems to be regionalized. This knowledge contributes to the plans for controlling these diseases, which are zoonoses that cause economic losses to the productive sector.

title: Physicochemical quality profiles of commercial oral tablets and capsules containing lutein – impact of insufficient specific sanitary regulations

description: Abstract Dietary supplements in many countries such as the USA do not require registration prior to commercialization. The Agência Nacional de Vigilância Sanitária (ANVISA) registers substances with functional properties as foods. Lutein is a carotenoid with antioxidant activity available on the market. However, no regulatory mandates exist to govern the design of quality control tests, which are necessary to ensure formulation effectiveness. Therefore, in the present study, tablet and dosage formulations from different manufacturers were tested following general methods outlined in the Brazilian and American Pharmacopeias. The averageweight, disintegration, content and dose uniformity assays were performed for all tablets and capsules, whereas hardness assays were only performed on tablets. None of the 10 formulations studied were found to be of satisfactory quality. Of all tablets tested, two had no-significant available lutein content, which may indicate adulteration. The capsules displayed adequate amounts of lutein, however had alarmingly negative disintegration and dissolution test results, which may contribute to non-bioavailability of lutein. All formulations analyzed are currently being marketed in the Brazilian and American markets. The low physicochemical performance in these formulations can be explained by the lack of specific regulations, which are necessary to ensure the quality of lutein-containing products on the market.

title: A physical look at musical theory

description: Abstract We present a discussion of several physical concepts present in the context of musical theory. We deal with important physical phenomena in the production and combination of musical sounds. From the elements of both musical language and physical language, we show relationships between the two forms of representing musical sound phenomena. We draw parallels between the ways of representing the various characteristics of sound and their rhythmic, melodic and harmonic combinations.

title: Medicinal Plants: versatility and concordance of use in the caatinga area, Northeastern Brazil

description: Abstract This study aims to investigate the diversity of native medicinal plants in a caatinga area, verifying the versatility of species and concordance of use among the informants, in the Angico de Cima community, in the city of Aurora, Ceará, Brazil. Ethnobotanical data were obtained through semi-structured interviews with key informants, adopting the snowball technique. The Relative Importance (RI) and Consensus Factor among Informants (ICF) were analyzed to indicate the most versatile species with the highest agreement of use, respectively. Within the 35 registered native species, eight presented great versatility, with a RI&gt; 1, standing out Ziziphus joazeiro Mart. (1.86) and Heliotropium indicum (L.) Lehm (1.67). The 60 therapeutic indications were grouped into 13 body systems categories, of which Genitourinary System Disorder and Nervous, had the highest agreement of use with ICF from 0.8, each. Some species, such as Heliotropium indicum, have a high RI, are scarcely indicated for therapeutic activities in caatinga and require studies that prove their medicinal properties.

title: Late Follow-up of Patients Submitted to Total Cavopulmonary Derivation: Clinical Aspects, Reinterventions, and Complications Interfering in Morbidity and Mortality

description: Abstract Objective: To identify main complications in outpatient follow-up, as well as factors before or during operation that may interfere in patient's evolution. Methods: Retrospective study of patients submitted to total cavopulmonary shunt with extracardiac conduit from 2000 to 2014 at the Hospital do Coração (São Paulo, Brazil) and who underwent clinical follow-up at this institution. Results: One hundred and fifty surgeries were performed and 59 patients maintained outpatient follow-up. The mean age of these patients at the time of surgery was 4.45 years (median of 45 months) and 70.2% of them were males. Among the patients undergoing outpatient follow-up, postoperative time at evaluation ranged from 10 days to 145 months; 30 (50.8%) patients had single left ventricle and 29 (49.2%) had single right ventricle (48.2% of these presented with hypoplastic left heart syndrome [HLHS]). Patients with single left ventricle had a higher percentage of reintervention-free survival, but without statistically significant difference. 40% of the patients had no complications and 35% of them presented with thrombosis at some point in the follow-up period, with ventricular dysfunction being the second most frequently found complication (15% of cases), mainly among patients with single right ventricle morphology (P=0.04). Between the patients currently under follow-up, 20 (35%) of them had been evaluated by ultrasonography and had some degree of hepatic congestion and/or hepatomegaly. 16.7% of the patients with such alteration had HLHS (P=0.057). Conclusion: Except for the right ventricular morphology, no other factor has been shown to interfere in late evolution after total cavopulmonary shunt.

title: Silver and gold nanoparticles from tannic acid: synthesis, characterization and evaluation of antileishmanial and cytotoxic activities

description: Abstract Gold (Au0) and silver (Ag0) nanoparticles were synthesized using tannic acid (TA) as both reducing and stabilizer. Nanoparticles formation, stability, and interaction with TA were compared to citrate-coated nanoparticles and monitored by UV-Vis, zeta potential, and transmission electron microscopy. TA coating resulted in a red-shift and broadening of bands compared to citrate-coated nanoparticles (NPs-Cit). AgNPs-TA and AuNPs-TA are negatively charged with mean surface charge of -29.4 mV and -29.6 mV, respectively. TEM images showed polydispersety of AuNPs-TA (6-42 nm) and aggregation of AgNPs-TA (12-71 nm). In vitro assays of Leishmania amazonensis promastigotes showed an increment of antileishmanial activity for AgNPs-TA in relation to AgNPs-Cit, while AuNPs-TA and AuNPs-Cit did not affect the protozoas at tested concentrations. CC50 value for AgNPs-TA suggested that TA attenuates nanosilver toxicity comparatively to its precursor (Ag+). This investigation can contribute to the development of new, green, and fast produced drugs aiming at leishmaniasis treatment.
