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 O objetivo do presente estudo foi avaliar as variáveis hematológicas e o perfil bioquímico renal sérico de cordeiros nascidos a termo e prematuros do nascimento às 48 horas de vida, bem como verificar a influência da dexametasona sobre tais variáveis. Foram constituídos quatros grupos experimentais: PN (cordeiros nascidos de parto normal, n=15, média de 146 dias); PNDEX (cordeiros nascidos de parto normal cujas mães receberam 16mg de dexametasona aos 141 de gestação, n=8, média de 143 dias); PRE (cordeiros prematuros nascidos de cesarianas aos 138 dias de gestação, n=10) e PREDEX (cordeiros prematuros nascidos de cesarianas aos 138 dias de gestação cujas mães receberam 16mg de dexametasona dois dias antes, n=9). Os valores médios do volume globular e de hemoglobina diminuíram ao longo das 48 horas de observação, nos quatro grupos experimentais, porém dentro dos limites fisiológicos para a espécie. Houve variação da concentração plasmática de proteínas totais em todos os momentos, sendo os menores valores no grupo PRE. A contagem leucocitária foi mais alta no grupo PN apenas no M24h. Ao longo do período, apenas o grupo PN mostrou diferença entre o M24h e os demais momentos, e o grupo PRE apresentou os menores valores de neutrófilos no M0h, M15min e M60min. As concentrações séricas de creatinina foram mais altas no grupo PRE no M60min, M24h e M48h. Em todos os grupos, houve diminuição no M24h e M48h. Os parâmetros avaliados foram afetados pela prematuridade na espécie ovina e a dexametasona teve influência positiva sobre a taxa de sobrevivência dos animais prematuros.

ABSTRACT The aim of the study was to evaluate hematologic parameters and renal biochemical profile of full-term and premature lambs from birth to 48 hours of life, and assess the effect of dexamethasone on such variables. Four experimental groups were formed: NDG (normal delivery group - lambs vaginally delivered, n=15, average of 146-day gestation); NDEXG (normal delivery with dexamethasone group - lambs vaginally delivered whose mothers received 16 mg of dexamethasone at 141 days of gestation, n=8, average of 143-day gestation); PRE (premature lambs born by cesarean section at 138 days of gestation, n=10) and PREDEX (premature lambs born by cesarean section at 138 days gestation, whose mothers received 16 mg of dexamethasone two days before, n=9). Mean values of cell volume and hemoglobin content decreased during the observation period of 48 hours in all groups, but within the physiologic limits for ovine species. There was significant variation in plasma concentration of total protein in all periods evaluated, with the lowest mean values in PRE group. The leukocyte count was significantly higher in PN group only in M24h. Throughout the observation period, only PN group showed differences between M24h and the other moments and PRE group showed the lowest values of neutrophils in M0h, M15min and M60min. Serum creatinine concentration was significantly higher in group PRE in M60min, M24h and M48h. In all groups, there was a decrease in M24 and M48. The evaluated parameters were affected by prematurity in sheep and dexamethasone had a positive effect on the survival rate of premature animals.
