Poly(amidoamine)-type dendrimers (PAMAM) were synthesized by divergent routes, and generations (G0.5, G1.0, G1.5, G2.0 and G2.5) along with hydroxylated half-generation polymers (G0.5-OH, G1.5-OH and G2.5-OH) were characterized by Fourier-transform infrared spectroscopy, thermogravimetric analysis and differential scanning calorimetry. Carbon dioxide (CO2) capture tests were performed using thermogravimetric analysis. Among the absorption temperatures tested, 60 °C was the most promising: 0.77, 1.08, and 1.14 mol CO2 L 1 for G0.5-OH, G1.5-OH and G2.5-OH, respectively, of CO2 and partial pressure of 45 kPa. This showed that dendrimers with larger molecular structures have more hydroxyl groups and consequently capture more CO2. However, at low partial pressures (< 2 kPa), CO2 solubility in PAMAM increased with temperature reduction, confirmed by Henry’s solubility constant (398.4 mol m3 kPa 1, in G2.5-OH at 40 °C). According to the thermodynamic properties of CO2 solubilization, the process was spontaneous (∆Gsol < 0) and exothermic (∆Hsol < 0).

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.

Introdução: Os aneurismas da artéria renal são raros e constituem um desafio ao tratamento endovascular. Nosso objetivo foi descrever e analisar as técnicas e táticas no tratamento endovascular do aneurisma da artéria renal, verificando os resultados a curto e médio prazos de uma série consecutiva de casos. Métodos: Estudo retrospectivo, de procedimentos realizados no período de janeiro de 2010 a dezembro de 2013, em que foram analisados: o sucesso técnico e terapêutico, a morbimortalidade, e a taxa de vazamentos e de reintervenções. Resultados: Em um total de seis pacientes tratados, a idade média foi de 41 ± 5 anos e todos eram do sexo feminino. A maioria apresentou aneurismas saculares tipo II (83,3%). Foram utilizadas técnicas de remodelamento com uso de stent e molas em quatro casos, embolização segmentar renal em um caso e tratamento com endoprótese Multilayer® em outro. O sucesso técnico e terapêutico foi de 100 e 83,3%, respectivamente. Em um paciente, houve isquemia de polo superior renal, que evoluiu para hematúria e dor incontrolável, necessitando de nefrectomia. Não ocorreram óbitos e nem oclusão das artéria renais nativas e de seus ramos durante o acompanhamento de 1 ano. Conclusões: O tratamento endovascular do aneurisma de artéria renal demonstrou ser uma alternativa viável à cirurgia convencional com baixa morbidade. O estudo detalhado da vascularização renal e da localização do aneurisma determina a escolha da técnica endovascular a ser utilizada. O aneurisma da artéria renal do tipo II foi a morfologia mais frequentemente encontrada e pode ser tratado com sucesso por técnicas de remodelamento com o uso de stent e mola.

Background: Renal artery aneurysms are rare and constitute a challenge to endovascular treatment. Our objective was to describe and analyze the techniques and strategies for the endovascular treatment of renal artery aneurysms verifying short and medium-term results in a consecutive series of cases. Methods: Retrospective study of procedures performed from January 2010 to December 2013, analyzing technical and therapeutic success, morbidity and mortality, the rate of endoleaks and reinterventions. Results: In a total of six patients treated, mean age was 41± 5 years and all patients were female. The majority of the patients had type 2 saccular aneurysms (83.3%). Remodeling techniques using stent and coils were used in four cases, embolization of renal polar branch was used in one case and treatment with a Multilayer® endoprosthesis in another case. Technical and therapeutic success rates were 100% and 83.3%, respectively. In one patient there was upper renal pole ischemia, which progressed to uncontrollable hematuria and pain, requiring nephrectomy. There were no deaths or occlusion of the native renal artery and its branches during the 1-year follow-up. Conclusions: Endovascular treatment of renal artery aneurysm proved to be a feasible alternative to conventional surgery with low morbidity. A detailed study of renal vasculature and aneurysm location determines the choice of the endovascular technique to be used. Type II renal artery aneurysm was the most frequent morphology observed and may be successfully treated by remodeling techniques using stents and coils.
