‘Mungo Here, Mungo There’
No full textThis chapter provides a definitive account of one of Dibdin’s best-known works, The Padlock, which has long been recognized as an important landmark in the representation of black characters in eighteenth-century theatre. The Padlock is most frequently associated with the librettist Isaac Bickerstaff, but this chapter redirects attention to the interaction of Bickerstaff’s words with Dibdin’s music, and to Dibdin’s celebrated performances as Mungo in one of the first comic plays to feature a major character in blackface on the British stage. Placing Mungo in the context of Dibdin’s numerous depictions of racial others (both Black and Oriental), the author argues that Dibdin’s racial performances reflect tensions surrounding slavery, social class, and imperial expansion, but remain stubbornly equivocal about these tensions as they turn captivity, servitude, and chattel slavery into the subject of comedy.</p
Visual and anatomical outcomes of intravitreal aflibercept for treatment-resistant neovascular age-related macular degeneration.
No full textA retrospective chart review of patients with persistent subretinal and/or intraretinal fluid, despite previous treatment with intravitreal ranibizumab (0.5 mg), who were switched to aflibercept injections, was performed. Treatment was three monthly aflibercept (2 mg) injections followed by dosing on pro re nata basis. Main outcome measures included changes in best corrected visual acuity (BCVA), 1 mm central subfield (CSF) retinal thickness, the height of the pigment epithelial detachment (PED), and subfoveal choroidal thickness on optical coherence tomography at 6 months. Thirty-one eyes of 30 patients were analyzed. The mean number of injections before aflibercept conversion was 34.4 ± 11.9.
After an average of 4.5 aflibercept injections (range 3 to 6) over 6 months, no significant change in BCVA was observed (P > 0.05). Compared with baseline, there was a significant reduction of the CSF retinal thickness (449 ± 179 versus 269 ± 145 μ m, P < 0.001), maximum PED height (262 ± 134 versus 183 ± 100 μ m, P < 0.001), and choroidal thickness (192 ± 67 versus 167 ± 51 μ m, P < 0.01).
Stable visual acuity and anatomical improvement were obtained for up to 6 months after aflibercept conversion. However, choroidal thinning related to treatment was observed
Roundtable: Message from Mungo and the Scales of Memory
No full textAnn McGrath and Andrew Pike's recent documentary film Message from
Mungo implicitly addresses several dimensions of the concept of ‘scales
of memory’, including the ‘deep time’ of Aboriginal habitation of the land,
transnational and national science in tension with local Aboriginal knowledge
and presence, and justice, power and authority. We invited Ann McGrath to
introduce and show her film as part of the conference program, and we asked
literary scholar and author Jeanine Leane, who comes from Wiradjuri Country in
south-west New South Wales to respond. The film screening and Jeanine’s deeply
felt and thoughtful response prompted an intense discussion. We were keen to
represent that previously unrecorded discussion in this Special Issue, so we later
invited a few of the participants to reconvene to discuss the film again and to
revisit some of the issues that had been raised. We recorded that session and the
following is drawn from it
Teste de condutividade elétrica para sementes de feijão-mungo-verde.
No full textA utilização de sementes de boa qualidade é fundamental para o estabelecimento adequado de uma lavoura. Para uma análise mais precisa da qualidade de sementes, faz-se necessário complementar as informações fornecidas pelo teste de germinação com testes de vigor, possibilitando, assim, selecionar os melhores lotes para comercialização e semeadura. Dentre esses testes, destaca-se o de condutividade elétrica. Objetivou-se neste trabalho estabelecer uma metodologia adequada para o teste de condutividade elétrica em sementes de feijão-mungo-verde, considerando períodos de embebição e número de sementes. Foram utilizados seis lotes de sementes e o teste de condutividade elétrica foi realizado com as seguintes variações: 100, 75 e 50 sementes embebidas em 75 mL de água destilada a 25 °C, com leituras realizadas após 3, 6, 9, 12, e 15 horas de embebição. O teste de condutividade elétrica conduzido com quatro sub-amostras de 50 sementes embebidas em 75 mL de água destilada permite a separação dos lotes a partir de 3 horas de embebição, mostrando-se promissor na avaliação da qualidade das sementes de feijão-mungo-verde
Avirulent mutants of Macrophomina phaseolina and Aspergillus fumigatus initiate infection in Phaseolus mungo in the presence of phaseolinone;levamisole gives protection
No full textTo evaluate the role of phaseolinone, a phytotoxin produced by Macrophomina phaseolina, in disease initiation,
three nontoxigenic avirulent mutants of the fungus were generated by UV-mutagenesis. Two of them were able to initiate
infection in germinating Phaseolus mungo seeds only in the presence of phaseolinone. The minimum dose of
phaseolinone required for infection in 30% seedlings was 2·5 μg/ml. A human pathogen, Aspergillus fumigatus was
also able to infect germinating seeds of P. mungo in the presence of 5 μg/ml concentration of phaseolinone. Phaseolinone
seemed to facilitate infection by A. fumigatus, which is not normally phytopathogenic, by reducing the immunity
of germinating seedlings in a nonspecific way. Levamisole, a non-specific immunopotentiator gave protection
against infection induced by A. fumigatus at an optimum dose of 50 μg/ml. Sodium malonate prevented the effects of
levamisole
Eco-friendly nano colloids for enhanced black gram (Vigna mungo) seed viability: experimental and computational analysis
No full textAbstract An experiment was designed to fabricate Polyvinylpyrrolidone-coated zein-zipped herbal molecules infused nano colloids (PZCA-NCs) for extending Vigna mungo seeds storability. PZCA-NCs was synthesized and characterized in Fourier Transform Infrared Spectroscopy (FTIR), X-Ray diffraction (XRD), Particle size analyser, Zeta Potential, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Energy-dispersive X-ray spectroscopy (EDAX). The bio-efficacy of PZCA-NCs on seed storability was tested under accelerated ageing. The sphere-shaped PZCA-NCs possess a 151 nm size with 44.5mV zeta potential at an encapsulation of 73.44% curcumin and 69.0% azadirachtin. The spectra of FTIR, UV –Vis, XRD, and TGA confirmed the functionality, composition, and stability of PZCA-NCs. The dialysis diffusion method was utilised to study the maximum cumulative release of biomolecules 6.1ppm (88.4%) azadirachtin and 64.57ppm (88.2%) curcumin at pH 7.4. Density functional theory (DFT) was used to determine the binding mode of molecules and examine ligand interactions in PZCA-NCs. PZCA-NCs treated seeds at 25 mL/kg enumerated higher germination, vigour index, α-amylase, dehydrogenase, and catalase and peroxidase activity under ageing. Seeds storage pathogen infection was reduced with an increase in the concentration of PZCA-NCs coating. The bioassay results on insect activity evidenced that PZCA-NCs at 15.76 mL/kg killed 50% and 40 mL/kg killed 100% of the storage insect Callosobruchus maculatus. Toxicity study on Macrophomina phaseolina showed that PZCA-NCs at 35 mL resulted in 0.8 cm mycelia growth with 91.11% inhibition zone, while at 45 mL had zero growth of fungal mycelia with 100% inhibition. The study concludes that PZCA-NCs act as an efficient seed invigoration material to extend the vitality of Vigna mungo seeds during ageing

No full textBackground. The interest in studying seaweed polysaccharides as plant growth biostimulants is recent and has generally focused on seaweed liquid extracts for compounds content that have positive effect on plant development. Within these compounds are the carbohydrates such as alginate and fucoidan, among others. Goals. To evaluate the effect of crude fucoidan and alginate on seed germination and their growth-stimulating activity on seedling of mung bean (Vigna radiata). Methods. Fucoidan and alginate from Eisenia arborea and Sargassum horridum at six different doses (0.6, 1.2, 2.5, 5, 10, and 20 mg m‒1 ) were evaluated on seed germination and seedling growth of mung bean. Results. Alginate from both algae species in this study did not show a significant effect on mung bean growth. Fucoidan from S. horridum produced the significant effect on mung bean growth by increasing root length (16.2%) and seedling total length (11.9%) at a concentration of 0.6 mg mL‒1 and an increase in the dry weight of the seedling (31%) at a concentration of 20 mg mL‒1 . While fucoidan from E. arborea had the higher effect on shoot growth (10.5%) and total length (10.7%), compared to the control when applied at a concentration of 10 mg mL‒1 . Conclusions. Overall, this study showed that fucoidan from both S. horridum and E. arborea can stimulate seedling growth and increase the germination percentage of mung bean seeds compared to the control.Antecedentes.

Adequação da metodologia do teste de envelhecimento acelerado para sementes de feijão mungo-verde
No full textO presente trabalho teve como objetivo avaliar os diferentes procedimentos do teste de envelhecimento acelerado com e sem solução salina para determinar o potencial fisiológico de sementes de feijão mungo-verde (Vigna radiata). O delineamento experimental utilizado foi inteiramente casualizado, em arranjo fatorial de 5 x 3, com 5 períodos de exposição (24, 48, 72, 96 e 120 h), 3 temperaturas (41, 43 e 45°C) e 4 repetições. Foram realizados os testes de envelhecimento acelerado tradicional e com solução de NaCl. O teste de envelhecimento acelerado tradicional foi realizado pelo método gerbox, com 40 mL de água destilada/gerbox nas temperaturas de 41, 43 e 45°C, por períodos de 24, 48, 72, 96 e 120 h. Em seguida, as sementes foram submetidas ao teste de germinação contendo 4 repetições de 50 sementes em cada tratamento. Em relação aos dados obtidos no teste de envelhecimento acelerado pelo método tradicional houve interação entre os períodos de exposição e as temperaturas. No teste com solução salina, os períodos de exposição às temperaturas não apresentaram interações. No envelhecimento acelerado tradicional, ocorre redução no vigor das sementes de feijão mungo-verde quando submetidas aos maiores períodos de exposição às temperaturas
Evaluation of Amino Acid Composition of Phaseolus mungo (Black Gram) and Labeo rohita (Rohu) In the Perspective of Human Dietary Requirements
No full textABSTRACT The present study is aimed at investigating the amino acid profiles of germinating black gram (Phaseolus mungo) seeds and the cultured fresh water carp (Labeo rohita) of the local ponds to evaluate their nutritional status in respect of human dietary requirements. The levels of 15 amino acids (free and protein hydrolysate) were estimated in the two experimental materials by HPLC analysis and relative percentages of amino acids and A/E ratios were calculated. The results indicate that the concentrations of essential amino acids are significantly higher in plant source as compared to fish muscle. Total amino acid content of L. rohita muscle tissue was found to be 1,248 nmoles/ml while that in P. mungo with coat is 1457.9 μmoles/ml and the pulse without coat had 540.6 μmoles/ml. The percentage of the total essential amino acid content in the chosen fish muscle is 28.42 and that in the pulse with coat and without coat are 31.82 and 37.96 respectively. Phenylalanine content is significantly lower in both the food items and hence may be included in the diet of hyperphenylalaninemia patients with dietary restrictions of phenylalanine intake. The significantly (P < 0.05) higher total amino acid and essential amino acid contents in the pulse with coat than that in the pulse without coat is suggestive of the fact that the pulse with coat is preferred for dietary consumption
