Laboratory of Plant Cytogenetics and Evolution, Department of Botany, Federal University of Pernambuco, Recife, Brazil.

Main Conclusion: The chloroplast genomes of Caesalpinia group species are structurally conserved, but sequence level variation is useful for both phylogenomic and population genetic analyses. Variation in chloroplast genomes (plastomes) has been an important source of information in plant biology. The Caesalpinia group has been used as a model in studies correlating ecological and genomic variables, yet its intergeneric and infrageneric relationships are not fully solved, despite densely sampled phylogenies including nuclear and plastid loci by Sanger sequencing. Here, we present the de novo assembly and characterization of plastomes from 13 species from the Caesalpinia group belonging to eight genera. A comparative analysis was carried out with 13 other plastomes previously available, totalizing 26 plastomes and representing 15 of the 26 known Caesalpinia group genera. All plastomes showed a conserved quadripartite structure and gene repertoire, except for the loss of four ndh genes in Erythrostemon gilliesii. Thirty polymorphic regions were identified for inter- or intrageneric analyses. The 26 aligned plastomes were used for phylogenetic reconstruction, revealing a well-resolved topology, and dividing the Caesalpinia group into two fully supported clades. Sixteen microsatellite (cpSSR) loci were selected from Cenostigma microphyllum for primer development and at least two were cross-amplified in different Leguminosae subfamilies by in vitro or in silico approaches. Four loci were used to assess the genetic diversity of C. microphyllum in the Brazilian Caatinga. Our results demonstrate the structural conservation of plastomes in the Caesalpinia group, offering insights into its systematics and evolution, and provides new genomic tools for future phylogenetic, population genetics, and phylogeographic studies.

EXPOSURE OF PEDIATRIC EMERGENCY PATIENTS TO IMAGING EXAMS, NOWADAYS AND IN TIMES OF COVID-19: AN INTEGRATIVE REVIEW.

Rev Paul Pediatr 2020 18;40:e2020302. Epub 2020 Dec 18.

Faculdades Pequeno Príncipe, Curitiba, PR, Brazil.

Objective: To analyze literature data about unnecessary exposure of pediatric emergency patients to ionizing agents from imaging examinations, nowadays and during times of COVID-19.

Data Sources: Between April and July 2020, articles were selected using the databases: Virtual Health Library, PubMed and Scientific Electronic Library Online. The following descriptors were used: [(pediatrics) AND (emergencies) AND (diagnostic imaging) AND (medical overuse)] and [(Coronavirus infections) OR (COVID-19) AND (pediatrics) AND (emergencies) AND (diagnostic imaging)]. Inclusion criteria were articles available in full, in Portuguese or English, published from 2016 to 2020 or from 2019 to 2020, and articles that covered the theme. Articles without adherence to the theme and duplicate texts in the databases were excluded.

Data Synthesis: 61 publications were identified, of which 17 were comprised in this review. Some imaging tests used in pediatric emergency departments increase the possibility of developing future malignancies in patients, since they emit ionizing radiation. There are clinical decision instruments that allow reducing unnecessary exam requests, avoiding over-medicalization, and hospital expenses. Moreover, with the COVID-19 pandemic, there was a growing concern about the overuse of imaging exams in the pediatric population, which highlights the problems pointed out by this review.

Conclusions: It is necessary to improve hospital staff training, use clinical decision instruments and develop guidelines to reduce the number of exams required, allowing hospital cost savings; and reducing children's exposure to ionizing agents.

CLINICAL-EPIDEMIOLOGICAL RELATION BETWEEN SARS-COV-2 AND KAWASAKI DISEASE: AN INTEGRATIVE LITERATURE.

Rev Paul Pediatr 2021 31;39:e2020217. Epub 2020 Aug 31.

Faculdades Pequeno Príncipe, Curitiba, PR, Brazil.

Objective: To analyze the current scientific literature to document, in an integrative review, the main findings that correlate Kawasaki disease (KD) to COVID-19.

Data Sources: The search was carried out in June 2020 in the following databases: Biblioteca Virtual em Saúde (BVS), periódico da CAPES and U.S National Library of Medicine (PubMed). The combination of descriptors used was [(COVID-19 OR SARS-CoV-2) AND (Kawasaki disease)], and the inclusion criteria stipulated were studies published from January 2019 to June 2020, without restriction of language or location, and available online in full. News, editorials, comments, and letters, as well as duplicates and articles that did not answer the guiding question were excluded.

Data Synthesis: A total of 97 articles were identified, of which seven comprised this review. The association of KD to the new coronavirus appears to trigger a severe clinical condition of vasculitis. Different from the usual, in this inflammatory syndrome, patients are older, and prevalence is higher in children from African or Caribbean ancestry; clinical and laboratory manifestations are also atypical, with a predominance of abdominal complaints and exaggerated elevation of inflammatory markers. In addition, there was a greater report of rare complications and greater resistance to the recommended treatment for KD.

Conclusions: Pediatric COVID-19 and its potential association to severe KD, still unfamiliar to health professionals, reinforces the importance of testing patients with vasculitis for the new coronavirus and the need to wage high surveillance and preparation of the health system during the current pandemic.

Phylogenetic impoverishment of plant communities following chronic human disturbances in the Brazilian Caatinga.

Ecology 2016 Jun;97(6):1583-92

Chronic disturbances, such as selective logging, firewood extraction and extensive grazing, may lead to the taxonomic and phylogenetic impoverishment of remaining old-growth forest communities worldwide; however, the empirical evidence on this topic is limited. We tested this hypothesis in the Caatinga vegetation--a seasonally dry tropical forest restricted to northeast Brazil. We sampled 11,653 individuals (adults, saplings, and seedlings) from 51 species in 29 plots distributed along a gradient of chronic disturbance. The gradient was assessed using a chronic disturbance index (CDI) based on five recognized indicators of chronic disturbances: proximity to urban center, houses and roads and the density of both people and livestock. We used linear models to test if mean effective number of lineages, mean phylogenetic distance and phylogenetic dispersion decreased with CDI and if such relationships differed among ontogenetic stages. As expected, the mean effective number of lineages and the mean phylogenetic distance were negatively related to CDI, and such diversity losses occurred irrespective of ontogeny. Yet the increase in phylogenetic clustering in more disturbed plots was only evident in seedlings and saplings, mostly because clades with more descendent taxa than expected by chance (e.g., Euphorbiaceae) thrived in more disturbed plots. This novel study indicates that chronic human disturbances are promoting the phylogenetic impoverishment of the irreplaceable woody flora of the Brazilian Caatinga forest. The highest impoverishment was observed in seedlings and saplings, indicating that if current chronic disturbances remain, they will result in increasingly poorer phylogenetically forests. This loss of evolutionary history will potentially limit the capacity of this ecosystem to respond to human disturbances (i.e., lower ecological resilience) and particularly their ability to adapt to rapid climatic changes in the region.

Ecotoxicological evaluation of waste water from nitrocellulose production.

J Environ Sci Health A Tox Hazard Subst Environ Eng 2013 ;48(2):197-204

Faculty of Planaltina, University of Brasília, Brasília, Brazil.

The present study evaluated the toxic potential and physicochemical characteristics of waste water generated in nitrocellulose production, including effluents from delignification, bleaching, nitration and mixture (composed of these three effluents), from a plant in the Paraiba Valley, São Paulo, Brazil. The test organisms used for toxicity assays were Daphnia similis, Danio rerio, Escherichia coli, Pseudomonas putida and Pseudokircheneriella subcaptata. The results showed that the effluents analyzed present acute and chronic toxicity for the organisms tested. Nitration effluent was the least toxic, while delignification and bleaching effluents were the most toxic. The naturally occurring pollutants in wood fiber and cotton, like lignin, probably contributed to effluents toxicity, in addition to higher concentrations of total dissolved solids, which are in non-compliance with Brazilian legislation, conductivity, chemical oxygen demand and color. The discharge of nitrocellulose effluent into an aquatic environment should only occur after appropriate treatment, due to their toxic characteristics.

Evaluation of the sensitivity of freshwater organisms used in toxicity tests of wastewater from explosives company.

Bull Environ Contam Toxicol 2012 Oct 8;89(4):915-20. Epub 2012 Aug 8.

Faculty of Planaltina, University of Brasília, Área Universitária n.1, Planaltina, DF CEP 73300-000, Brazil.

Explosives industries are a source of toxic discharge. The aim of this study was to compare organisms sensitivity (Daphnia similis, Danio rerio, Escherichia coli and Pseudomonas putida) in detecting acute toxicity in wastewater from two explosives, 2,4,6-TNT (TNT) and nitrocellulose. The samples were collected from an explosives company in the Paraiba Valley, São Paulo, Brazil. The effluents from TNT and nitrocellulose production were very toxic for tested organisms. Statistical tests indicated that D. similis and D. rerio were the most sensitive organisms for toxicity detection in effluents from 2,4,6-TNT and nitrocellulose production. The P. putida bacteria was the organism considered the least sensitive in indicating toxicity in effluents from nitrocellulose.

Ecotoxicological evaluation of wastewater from 2.4.6-TNT production.

J Environ Sci Health A Tox Hazard Subst Environ Eng 2012 ;47(2):184-91

Faculty of Planaltina, University of Brasília, Planaltina, DF, Brazil.

During the manufacture of explosives, large amounts of water are used to remove unwanted by-products generated. This water in turn, ends up in wastewater treatment plants or water bodies. The aim of this study was to evaluate the toxic potential of effluent generated by 2.4.6-Trinitrotoluene (TNT) production, yellow water, red water and mixture of yellow and red water, produced from a plant located in the Paraíba Valley, São Paolo state, Brazil. Daphnia similis, Danio rerio, Escherichia coli, Pseudomonas putida and Pseudokircheneriella subcaptata were used as test organisms. Physicochemical parameters such as color, pH, conductivity, total dissolved solids, dissolved oxygen, chemical oxygen demand (COD) and biochemical oxygen demand (BOD) were evaluated. Effluent from 2.4.6-TNT production was extremely toxic to all test organisms. The physicochemical parameters evaluated showed high levels of conductivity (from 41.533 to 42.344 μS /cm) and chemical oxygen demand (COD of 8471 to 27.364 mg/L) for the effluents analyzed.

[Extract of Passiflora edulis in the healing of colonic anastomosis in rats: a tensiometric and morphologic study].

Acta Cir Bras 2006 ;21 Suppl 3:16-25

Universidade Federal do Maranhao.

Introduction: Investigation of new substances with therapeutic effects have been done trying to isolate, extract or purify new compounds of vegetable origin. The Passiflora edulis (maracujá) species from the Plassifloracia family, originated from the tropical and subtropical regions of the american continent, is found all over Brazil. It is commonly used as a sedative, painkiller and anti-inflammatory drug and also for the treatment of skin wounds, lesions and Erisipelae.

Purpose: To evaluate the wound healing in colonic anastomosis in rats that received an hydro-alcoholic extract of Passiflora edulis peri-operatively.

Method: 40 wistar rats were used distributed into two groups of 20 rats each, named: Passiflora edulis group (GP) and control group (GC). The rats of each group were separated into two subgroups of 10 animals each and were evaluated on the 3rd and 7th postoperative days. The surgical procedure consisted of a section of the left colon, 5 cm above the peritoneal reflexion with preservation of the vascular elements. Intestinal continuity was restored by an end-to-end single layer anastomosis. The Passiflora edulis group received an intraperitoneal application of the hydro-alcoholic extract in the dosage of 250 mg/kg. The control-group received one intraperitoneal dose of a saline with the same volume of the GP. The parameters evaluated were: macroscopic aspects of the wall and abdominal cavity, perianastomotic (adherences), bursting pressure, inflammatory tissue reaction on the anastomotic wound.

Results: The macroscopic aspects did not differ between the groups. No rupture in the anastomotic wound was seen in any rat. Regarding the bursting pressure, it was noticed that the average pressure was significantly higher in the subgroup that received the Passiflora edulis extract on the 3rd day (P3) (42.6 +/- 17.8 mmHg vs. 25.4 +/- 14.1 mmHg, p=0.028), as compared to the control sub-group (C3). However, on the 7th day, bursting pressure was similar in both groups (p=0.447). Rats from the C7 sub-group had a mean bursting pressure of 203.0 +/- 50.0 mmHg vs. 187.3 +/- 39.5 mmHg in the C7 sub-group. In the histologic analysis the polymorphic nuclear cells were more frequent in the C3 group, with significant differences (p=0.034). The monomorphic nuclear cells (MMN) and the fibroblastic proliferation were more frequent in the P3 sub-group with a significant difference, p=0.02 to MMN, and p=0.001 to the fibroblastic proliferation. On the 7th day there was a significant difference in all histologic criteria stained by hematoxin-eosin and Masson Trichomic (p<0.05) in the sub-group that received the Passiflora edulis extracts.

Conclusion: The peri-operative administration of the hydro-alcoholic extract of Passiflora edulis has a positive influence on the healing of colonic anastomosis in rats.
