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.

Abstract Aim: This study evaluated the effects of 10 weeks of combined exercise training on the salivary oxidative profile of hypertensive and normotensive postmenopausal women. Methods: Twenty-six non-obese postmenopausal women were divided into two groups: the hypertensive group (HT; n = 13; 58.9 ± 3.9 years; and BMI of 27.7 ± 4.6 kg/m2) or the normotensive group (NT; n = 13; 52.7 ± 5.2 years; and BMI of 26.9 ± 2.9 kg/m2). They performed 30 sessions of combined exercises over 10 weeks: 45 min per session, three times a week. Resting saliva samples were collected after an overnight fast to evaluate salivary nitrite levels and oxidative stress markers before and after training. Results: Two-way ANOVA showed that there was no difference in the responses over time between the hypertensive and normotensive groups in catalase, superoxide dismutase salivary activity, total antioxidant capacity, or lipid peroxidation. However, superoxide dismutase activity (δHT -0.87 ± 14.53 SOD/mg protein; δNT: 7.13 ± 9.39 SOD/mg protein; p < 0.01) and nitrite levels (δHT 10.32 ± 60.83 mM; δNT 101.92 ± 149.57 mM; p = 0.03) were higher overall in the hypertensive group compared to the normotensive group. Moreover, salivary nitrite levels increased over time (p = 0.04) in both groups. Conclusion: 10 weeks of combined exercise training did not change salivary oxidative stress markers in either normotensive or hypertensive postmenopausal women, although, after exercise training, nitrite levels increased in both groups, even with higher baseline salivary nitrite levels in hypertensive women. Thus, recurrent exercise seems to be a safe strategy after menopause from the standpoint of oxidative stress, regardless of the presence of hypertension.

Objetivo: avaliar se a alteração na atividade da alfa amilase salivar está associada à ansiedade e ao estresse dos profissionais de enfermagem hospitalar e, se a ansiedade e o estresse estão associados aos fatores sociodemográficos, epidemiológicos e laborais. Método: estudo transversal, quantitativo, desenvolvido com 210 profissionais de enfermagem de uma instituição hospitalar. Para a coleta de dados, utilizouse um questionário de caracterização dos trabalhadores, o Inventário de Ansiedade de Beck, o Inventário de Sintomas de Stress para Adultos de Lipp e as amostras de saliva coletadas durante os turnos de trabalho. Os dados foram analisados de forma descritiva e inferencial utilizando os softwares Statistical Package for the Social Science e GraphPad Prism. Resultados: a maioria dos profissionais apresentou estresse e ansiedade. As variáveis faixa etária, quantidade de filhos, uso de medicamentos e carga horária de trabalho estavam associadas à ansiedade; faixa etária, tabagismo e uso de medicamentos estavam associadas ao estresse. Observouse um aumento da atividade da alfa amilase salivar no meio do turno de trabalho. Os profissionais que tinham estresse e ansiedade apresentaram alteração significativa da alfa amilase no turno da noite. Conclusão: as alterações na atividade da alfa amilase estavam associadas à ansiedade e ao estresse dos profissionais de enfermagem, demonstrando que essa enzima pode ser um possível biomarcador de ansiedade e estresse em trabalhadores.

Objective: to assess if changes in salivary alpha-amylase activity are associated with anxiety and stress among hospital nursing professionals and whether anxiety and stress are associated with sociodemographic, epidemiological, and occupational factors. Method: cross-sectional, quantitative study, carried out with 210 nursing professionals from a hospital. For data collection, we used a questionnaire to characterize workers, Beck’s Anxiety Inventory, Lipp’s Stress Symptoms Inventory for Adults and samples and saliva samples collected in work shifts. The data were analyzed descriptively and inferentially using the software Statistical Package for the Social Science and GraphPad Prism. Results: most professionals experienced stress and anxiety. The variables age group, number of children, use of medication and workload were associated with anxiety; age group, smoking and medication use were associated with stress. An increase in the salivary alpha-amylase activity was observed in the middle of the work shift. Professionals who had stress and anxiety had significant changes in alpha-amylase in the night shift. Conclusion: changes in salivary alpha-amylase were associated with anxiety and stress among nursing professionals, indicating that this enzyme can be a possible biomarker of anxiety and stress in workers.
