Relevance. A wide variety of oral care products is available nowadays. Sometimes aggressive advertising rather than doctor’s advice determines our patients’ choice. In our research, we provide evidence of the clinical use of toothpaste containing fluoride and sodium bicarbonate.Materials and methods. During four weeks, we followed up a group of students who used the toothpaste containing 1400 ppm fluoride and 67% aqueous sodium bicarbonate solution. The clinical, biochemical and microbiological tests and saliva crystallization score assessed the characteristics stated by the manufacturer.Results. The statistically significant correlation between all studied criteria is evidence of the effectiveness of the toothpaste. In addition to the significant remineralization and antiplaque effect, biochemical and microbiological tests confirmed the anti-inflammatory effect of the toothpaste. An immediate cleaning effect was observed after the first brushing as well as in long-term use.Conclusion. Improvement of oral hygiene indices and reduction of periodontal inflammation confirmed the successful result of the comprehensive treatment of chronic gingivitis.

ABSTRACT Peperomia is the second most diverse genus of Piperaceae, with an estimated 1,600 species and a pantropical distribution. This work aims to present a taxonomic synopsis of the genus in the State of Roraima, in the extreme north of the Brazilian Amazon forest and belonging to the central-south portion of the Guayana Shield. Based on collecting expeditions and analysis of specimens in various herbaria, 23 taxa were recognized, with two new records for the State and one of them, a new record for Brazil. The taxa are differentiated mainly by phyllotaxis, shape and size of their leaves, in addition to habit and fruits. They have been found in areas of lowland, submontane, montane, tepui and floodplain (várzea) forests and mostly show a distribution restricted to the Neotropics. Some species in the state are presently known exclusively from Mount Roraima, and restricted to a few specimens.

Paxillus is a neotropical genus belonging to the subfamily Passalinae widespread from Mexico to Argentina. Brazil is known to harbor five species belonging to this genus with most of them presenting at head a flattened central tubercle lacking a free apex. However, one of these species, Paxillus macrocerus Reyes-Castillo & Fonseca, differs from that pattern by having a long central tubercle with a completely free apex. The present study describes and illustrates another new species, which has been found in the Brazilian Amazon, showing this same characteristic.

There are only a few published bat surveys from the southwestern Brazilian Amazon, but recent studies have reported additional bats species in the region. We provide the first list of bat species from Floresta Estadual do Antimary (Antimary State Forest) and record for the first time Glyphonycteris sylvestris Thomas, 1896 and Phylloderma stenops Peters, 1865 in the state of Acre, increasing to 64 the number of species known from this state. Our survey enlarges the known geographic range of G. sylvestris in Brazilian territory and improves the inventory of bat species in a poorly sampled region of the Amazon.

Abstract: We report range extensions for three species of Amazonian erethizontids, Coendou bicolor, C. ichillus, and C. nycthemera. We record C. ichillus for the first time in Brazil, from Rio Japurá, state of Amazonas. We record C. bicolor for the first time in the state of Amazonas, which represents a range extension of approximately 905 km. We also extend the occurrence of C. nycthemera 620 km to the south into Mato Grosso state. All records are based on museum specimens, highlighting the importance of scientific collections as biodiversity databases and emphasizing the lack of research on Amazonian porcupines.

AbstractThe Brazilian Northern region registered a high incidence of COVID-19 cases, particularly in the state of Pará. The present study investigated the risk factors associated with the severity of COVID-19 in a Brazilian Amazon region of 100,819 cases. An epidemiological, cross-sectional, analytical and demographic study, analyzing data on confirmed cases for COVID-19 available at the Brazilian Ministry of Health's surveillance platform, was conducted. Variables such as, municipalities of residence, age, gender, signs and symptoms, comorbidities were included and associated with COVID-19 cases and outcomes. The spatial distribution was performed using the ArcGIS program. A total of 100,819 cases were evaluated. Overall, patients had the mean age of 42.3 years, were female (51.2%) and with lethality reaching 4.79% of cases. Main symptoms included fever (66.5%), cough (61.9%) and sore throat (39.8%). Regarding comorbidities, most of the patients presented cardiovascular disease (5.1%) and diabetes (4.2%). Neurological disease increased risk of death by nearly 15 times, followed by obesity (5.16 times) and immunodeficiency (5.09 time). The municipalities with the highest incidence rate were Parauapebas, Canaã dos Carajás and Jacareacanga. Similarity between the Lower Amazon, Marajó and Southwest mesoregions of Pará state were observed concerning the highest morbidity rates. The obtained data demonstrated that the majority of cases occurred among young adults, females, with the classic influenza symptoms and chronic diseases. Finally, data suggest that the highest incidences were no longer in the metropolitan region of the state. The higher lethality rate than in Brazil may be associated with the greater impacts of the disease in this Amazonian population, or factors associated with fragile epidemiological surveillance in the notification of cases of cure.

Abstract We present three new records of Remijia (Rubiaceae) for Brazil. Remijia globosa and R. reducta were known only from Venezuela and R. hispida from Venezuela and Colombia. During a revisional study of the genus, we found these three species had also been collected in the state of Amazonas, Brazil. Additionally, we found a collection of R. hispida from Venezuela, near La Esmeralda, at an altitude over 2,000 m higher than previously known for this species. This contributes to the knowledge of Remijia distribution, especially in the Amazon basin and in the Brazilian part of the Guiana Shield.

This study evaluated the Arctiini fauna of the Serra do Pardo National Park (Pará, Brazil) between 22 September and 3 October 2011. Light traps were left one night in each sampling site (SS) from 18:00 h to 6:00 h of the next day. The following parameters were evaluated: richness (S), abundance (N), diversity index (H’), Shannon uniformity (U) index, and Berger-Parker dominance (BP). Richness was estimated using the non-parametric methods Chao1, Chao2, ACE, ICE, Jackknife1, Jackknife2 and Bootstrap. A total of 3,247 specimens were captured, belonging to 221 Arctiini taxa; 32 of these are new records for the state of Pará and, of these, six are new records for the Brazilian Amazon. The Arctiini fauna is very rich and uniform. The richness estimator and rarefaction curve indicated the need for increased sampling efforts in the area.
