title: Assessment of antioxidant potential in seed extracts of Nyctanthes arbor-tristis L. and phytochemical profiling by Gas Chromatography-Mass Spectrometry system

description: Abstract The present study has been carried out with the seed extracts of Nyctanthes arbor-tristis L. (Parijat) and evaluates its antioxidant potential and profiling the phytochemical constituents by Gas Chromatography-Mass Spectrometry (GC-MS) analysis. The antioxidant potential of the seed extracts was measured by four different in vitro assay like 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, superoxide anion free radical scavenging activity, ferric reducing antioxidant power (FRAP) and lipid peroxidation inhibition potential (LPIP) assay. The total phenol content (TPC) and total flavonoid content (TFC) were estimated. The ethyl acetate extract (EAE) of seeds showed potential DPPH free radical scavenging activity (EC50 129.49±3.55µg/ml), superoxide anion radical (EC50 969.94±8.03µg/ml) and LPIP (EC50 452.43±5.07 µg/ml) activities. The total phenol content was maximum in aqueous extract (AQE) which was 201.00±0.20 µg/mg gallic acid equivalent. The EAE was rich with total flavonoid and it was found to be 34.50±0.40 µg/mg rutin equivalent. The EAE was subjected for phytochemical-profiling using GC-MS system. The presence of different phytoconstituents supports the medicinal value of the seeds. The results suggest that EAE constitutes a promising new source of novel compounds. Further, it can be used for isolation and purification of specific compounds which have good antioxidant activities and possess useful biological activities.

title: Progeny evaluation and early selection for plant height in Acacia mearnsii improve genetic gains

description: Abstract Acacia mearnsii De Wild. is one of the most widely cultivated forest species in Brazil. Despite its importance, studies on breeding strategies for this species are scarce. Therefore, the aim of this study was to evaluate the progeny and develop early selection strategies for A. mearnsii. Individuals of half-sib progenies were classified according to their genotypic value and selected based on their relative performance. The additive effect was only significant for plant height. The best progenies and plants should be selected based on plant height after approximately 60 days of being in nursery and 2 years of field cultivation. This strategy eliminates the worse progenies, discards inferior genotypes in the nursery, eliminates unselected genotypes based on plant height before flowering, and intercrosses only the best plants in field cultivation. This resulted in an annual genetic gain of 3% for plant height and 2% for diameter at breast height.

title: Eustrongylides spp. (Nematoda: Eustrongylidae) in Polypterus endlicheri in central Rio Grande do Sul, Brazil

description: Abstract The demand for ornamental fish has increased in recent years in Brazil, however, the aquatic environment of artificial breeders facilitates the invasion of pathogens, including parasitic zoonoses, which are a limiting factor for production causing economic losses in creations. Knowledge of the distribution of agents causing parasitic diseases is important so that we can intervene in breeders, therefore, the objective of the present work is to report the occurrence of infection by Eustrongylides spp. (Nematoda: Eustrongylidae) in Polypterus endlicherii (Polypteriformes: Polypteridae) in central Rio Grande do Sul, Brazil. The nematode was identified after being released a cyst in the scales, of a fish of the species P. endlicherii. It can be concluded that this is the first record of the occurrence of Eustrongylides spp. larvae in fish in Rio Grande do Sul, showing that the parasite is present in the central region of the state. Therefore, further studies should be carried out in order to verify the presence of the parasites in fish intended for human consumption. It should also be noted the need to be more careful when feeding fish with oligochaetes, especially those intended for human consumption.

title: Epistemological Reflections and Doing Science in Contemporary Administration

description: ABSTRACT RAC has prioritized studies that advance the scientific debate in the field of contemporary administration, favoring original and interdisciplinary studies with epistemological approaches expanding conceptual boundaries and innovatively connecting theory and practice. RAC values responsible knowledge production that contributes in and out of academia. Given this, it is vital to reinforce a research agenda for administration, broadening the horizons of epistemological and metatheoretical discussions on the content of the knowledge produced and on how this knowledge is produced. Such a research agenda must focus on the field’s scientific practices, the scope and limits, and the consequences of these practices in academia and beyond. This editorial presents some reflections and contributions to thinking about new epistemological paths and supporting the use of new praxeological avenues in the field. The intention is to help consolidate a research agenda on epistemology and practices in the scientific work of administration oriented toward the most prominent societal challenges.

title: The efficacy of corticosteroid after facial nerve neurorrhaphy: a systematic review and meta-analysis of randomized controlled trial

description: Abstract Objectives: The benefit of corticosteroids following facial nerve neurorrhaphy in the setting of complete transection is questionable. This systematic review and meta-analysis aimed to evaluate corticosteroid efficacy on facial nerve regeneration and functional recovery after complete disruption and neurorrhaphy. Methods: Randomized controlled trials on both human and animal models from Ovid MEDLINE and Ovid EMBASE studying corticosteroid efficacy in complete facial nerve disruption followed by neurorrhaphy were included. Data were extracted and pooled for meta-analysis. The outcomes were evaluated from electrophysiology, histology, and functional recovery. However, no randomized controlled trial in human was performed. Possibly, performing human trials with histopathology may not be feasible in clinical setting. Results: Six animal studies (248 participants) met inclusion criteria. Electrophysiologic outcomes revealed no differences in latency (Standardized Mean Difference (SMD) = −1.97, 95% CI −7.38 to 3.44, p = 0.47) and amplitude (SMD = 0.37, 95% CI −0.44 to 1.18, p = 0.37) between systemic corticosteroids and controls. When analysis compared topical corticosteroid and control, the results provided no differences in latency (Mean Difference (MD)=0.10, 95% CI −0.04 to 0.24, p = 0.16) and amplitude (SMD = 0.01, 95% CI −0.08 to 0.10, p = 0.81). In histologic outcomes, the results showed no differences in axon diameter (MD = 0.13, 95% CI −0.15 to 0.41, p = 0.37) between systemic corticosteroid and control; however, the result in myelin thickness (MD = 0.06, 95% CI 0.04 to 0.08, p &lt; 0.05) favored control group. When comparing systemic corticosteroid with control in eye blinking, the results favored control (MD= 1.33, 95% CI 0.60 to 2.06, p = 0.0004). Conclusions: This evidence did not show potential benefits of systemic or topical corticosteroid deliveries after facial nerve neurorrhaphy in complete transection when evaluating electrophysiologic, histologic, and functional recovery outcomes in animal models.

title: Soybean adaptability and stability analyzes to the organic system through AMMI, GGE Biplot and mixed models methodologies

description: ABSTRACT: This research determined the adaptability and stability of soybean yield for organic systems in different environments. Grain yield data (GY, kg ha-1) from experiments with six soybean genotypes evaluated in six environments in Brazil and one environment in Paraguay were used. The experimental design used was randomized blocks, organized in an incomplete factorial scheme, with six environments in Brazil (Toledo- PR, Palotina- PR, Mangueirinha- PR, Três Passos- RS, Passo Fundo- RS, Major Vieira- SC) and one in Paraguay (Bela Vista do Norte- PY) with six soybean genotypes (BRS 284, BRS 391, BRS 511, BRS 523, BRS 525, BRS 535) arranged in four replications per environment. BRS 511 genotype was characterized by high average grain yield and stability by the AMMI method. BRS 284 genotype was identified as the ideal genotype in the GGE biplot method. WAASBY and BLUP index selected BRS511 and BRS284 genotypes.

title: Molecular marker-assisted selection for seedlessness in atemoya breeding

description: Abstract Perennial plant breeding is an expensive and time-consuming process, mainly due to the extended growth time for juveniles. In these cases, the use of molecular marker-assisted selection (MMAS) allows for the selection of a characteristic of interest at the seed or seedling stages. The objective of this work was to characterize the segregation of the INO locus and to use MMAS for the early selection of seedless genotypes of atemoya 'Gefner' [(G; Annona cherimola Mill. × Annona squamosa L.) × Brazilian seedless (Bs; Annona squamosa)]. After primer validation and MMAS, 24 plants of the F2 population were selected and designated as candidate genotypes for the absence of seeds, as INO alleles were absent in them. For further studies on breeding programs for this species, 53 heterozygous seedlings were considered as genetic resources during selection.

title: Screening of tomato hybrids for resistance to Fusarium wilt

description: Abstract Few commercial genotypes of tomato are resistant to Fusarium wilt (Fusarium oxysporum f. sp. lycopersici [FOL]), especially to race 3. We developed five intraspecific hybrids of Solanum lycopersicum (FOX1 to FOX5) and assessed them for agronomic traits and resistance to FOL races 1, 2, 3, and a mixture of these races. FOX1 and FOX4 were resistant to all races and the race mixture but did not have the desired agronomic traits. Next, FOX1 and FOX4 were assessed as rootstocks of the cherry tomato Sweet Heaven. The grafting of Sweet Heaven on FOX4 did not reduce growth, gas exchange, yield, or fruit quality. When FOX1 was used as a rootstock, the fruits exhibited a reduction in firmness, fruit pulp pH, and total soluble solids by 14.3%, 1.2%, and 6.75%, respectively. Thus, the hybrid FOX4 can be used as a rootstock for Sweet Heaven to manage Fusarium wilt.

title: Bioactive compounds and antioxidant activity of leaves from olive trees grown in Paraná, Brazil

description: Abstract The objective of this work was to evaluate the bromatological composition, bioactive compounds, antioxidant activities, and color of the leaves of olive cultivars Arbosana, Arbequina, Frantoio, Manzanilla, and Koroneiki in northwestern Paraná, Brazil. Leaves of each cultivar were collected for the experiment, which was carried out in a completely randomized design. The dry matter (DM) of olive leaves contains mostly carbohydrates (56.15 to 59.42 g 100 g-1 DM) and fibers (17.37 to 19.73 g 100 g-1 DM) in its bromatological composition. The total polyphenol content ranges from 13.27 to 22.81 mg GAE g-1, with cultivar Manzanilla standing out, and the flavonoid content from 6.50 to 7.65 mg QE g-1. Manzanilla shows the highest antioxidant activity of 93.56 and 78.15% in the DPPH and ABTS assays, respectively. When compared with the other cultivars, Manzanilla and Koroneiki have leaves with a higher green intensity and total chlorophyll content of 0.958 and 0.833 mg 100 mL 1, respectively. In the ABTS assay, there is a correlation both between total polyphenol content and antioxidant activity and between chlorophyll content and antioxidant activity. Olive leaves have characteristics that allow their application as an additive or ingredient for the development of food products with satisfactory antioxidant activity.
