Mucormycosis, a post-COVID infection: possible adjunctive herbal therapeutics for the realigning of impaired immune-metabolism in diabetic subjects
Authors: Panchamoorthy Rajasekar , Prabhakar Prathinisha 
Published: October 2022

Summary
Cytokine storm is believed as a major root cause for multi-organ failure and death in severely infected diabetic patients with COVID-19. This condition is treated with anti-inflammatory drugs, mainly steroids, to recover people from critical conditions. However, steroid therapy causes immune suppression and uncontrolled hyper-glycaemia in post-COVID. This altered immune-metabolism provides a fertile environment for the infection of a black fungus, Rhizopus arrhizus which causes mucormycosis in diabetic patients. It is a life-threatening infection causing death in different countries. It is treated either with anti-fungal drugs, surgical debridement, or adjunctive therapies. The available therapies for mucormycosis have been associated with several drawbacks. Thus, the present review has explored and suggested herbs-spices based adjunctive therapy for possible realignment of the impaired immune system in the post-COVID diabetic subjects. The consumption of herbal therapeutics after COVID-19 could realign the impaired immune-metabolism in the post-COVID and thereby exert prophylactic effects against mucormycosis. Furthermore, the suggested herbal sources could help in the discovery of novel therapeutics against the COVID-19 associated mucormycosis.

Published: October 2022

Summary

Introduction: Ephedra foliata Boiss. ex C.A. Mey of the Ephedraceae family is an evergreen shrub distributed throughout North Africa and Southwest Asia. It has been a characteristic source of alkaloids like ephedrine, pseudoephedrine and other related mixes, which are of great importance for their biological and pharmacological potential.

Objective: This study is aimed to evaluate the antimicrobial potential and phytochemical constituents studies on stem, leaves and flowers extracts of E. foliata.

Method: The air-dried plant sample was powdered with an electric grinder, then extracted successively with solvents, namely petroleum ether, petroleum benzene, ethyl acetate, methanol, and aqueous using Soxhlet apparatus for 72 hours. The solid matter was separated by filtration and then solvents were evaporated with a vacuum rotary evaporator to obtain the crude extracts. Freshly prepared crude extracts were subjected to the standard procedures of preliminary phytochemical screening for the investigation of the presence or absence of different phytoconstituents. The result showed the presence of reducing sugars, flavonoids, and cardiac glycosides. Antimicrobial activity of the crude extract was determined by agar well diffusion method.

Results: Ethyl acetate extract showed the highest antimicrobial activity against all the tested pathogens (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Yersinia enterocolitica, Streptococcus pneumonia, Aspergillus terreus, Cladosporium herbarum and Candida tropicalis). All five extracts inhibited the growth of Y. enterocolitica.

Conclusion: The antimicrobial properties of E. foliata extracts are of great interest in light of the ongoing threat of microbial resistance to conventional antibiotics. Phytoconstituents present in the E. foliata extracts might be a good alternative to modern antimicrobials as a natural compound.

Published: October 2022

SummaryIntroduction:Valorisation of the genetic resources of crop plants is related to the protection of biodiversity.Objective:The morphological and agricultural valorisation of 21 genotypes of flax (Linum usitatissimumL.) was carried out. Ten accessions of fibre flax were investigated: Fortuna, Izolda, Lazur, Swadzimski, Zwisły, Ariadna, Bryta, Waza, Milenium, Golęciński from Poland; Jordan, Tabor from Czech Republic; Argos, Venus from France; Baltuciai, Vega 2 from Lithuania: Irma, Persey from Ukraine; Rusicz from Russia and Alba from The Netherlands. The evaluation was also made for one linseed varieties from France, Drakkar.Methods:The studied genotypes of flax were the research material in two locations: in 2010 in Pętkowo and in 2011 in Wojciechów. The valorisation of the tested morphological and agricultural traits was carried out traditionally. Some of the valorised morphological features were also presented in the form of data for the International Flax Database.Results:Venus, Argos, Tabor and Jordan are varieties with a high fibre content in the stem. The highest fibre yield was found in Vega 2 in Pętkowo and Milenium in Wojciechów, and the lowest in Lazur in Pętkowo and Drakkar in Wojciechów. In both locations and years, the following cultivars were characterized by the highest seed yields: Lazur, Jordan, Argos, Vega 2, Golęciński and Persey. Cultivars Milenium in Pętkowo and Bryta in Wojciechów were the least valuable in terms of seed yield.Conclusions:Morphological and agricultural valorisation differed in both locations and years. The conducted experiment confirms the literature data that the valorisation results of flax accessions depend on agrometeorological conditions.

Published: October 2022

Summary
Fatty acids are important structural and functional elements of human body. We can distinguish several types: among others polyunsaturated fatty acids, which include omega-3 fatty acids (ω-3PUFA) and omega-6 fatty acids(ω-6PUFA). The first group has pleiotropic health-promoting effects, while the second group, ω-6PUFA, negatively affects the homeostasis of the human body and contributes to the development of numerous diseases. Both the amount and the relative ratio of these acids in the diet is an important factor affecting health and quality of life.
Laboratory and clinical studies indicate that ω-3PUFA have a positive effect on the therapy of illnesses such as obesity and inflammatory bowel disease (IBD). ω-3 PUFA supplementation also appears to have a helpful effect in the adjuvant treatment of colorectal cancer and recovery.

Summary

Introduction:
Gynura procumbens is an important medicinal plant that contains different types of chemical constituents that show tremendous curative effects.

Objective: The aim of this research work was comparative karyomorphological analysis between in vitro and in vivo grown selected medicinal plant species.

Methods: The roots were collected properly from naturally grown plants and in vitro propagated plants and pretreated with 1,4-para-dichlorobenzene (PDB) for 2.00 – 3.00 hours at room temperature. After pretreating with PDB the roots were washed thoroughly and kept in 1:3 (v/v) aceto-alcohol for 24 hours and then, transferred to 70% alcohol (v/v) for preservation. After that completing staining process, prepared slides were observed under microscope for karyotype analysis & ideogram preparation.

Results: This research work reveled that both mother plant and tissue culture raised plants had 2n=20 chromosomes in somatic cell. No telocentric or acrocentric chromosome observed in the basic set of chromosomes. Both plants had 3 submetacentric and 7 metacentric chromosomes in the basic set of chromosomes. The centromeric formula for both plants was 3sm + 7m. The length of individual chromosome of in vivo plants ranged from 6.20 to 11.24 µm, whereas chromosome length of in vitro grown plants ranged from 6.08 to 11.22 µm. The total form percent (TF%) of naturally grown plants and micro-propagated plants were same (43.93%). Mother plant had 2A type of karyotype, the formula being 2Lsm + 4Msm + 4Mm + 10Sm. In vitro grown plant had also 2A type of karyotype which could be expressed by the formula, 2Lsm + 4Msm + 2Mm + 12Sm.

Conclusion: The results of cytological studies point out that chromosome numbers of naturally grown plants and micro-propagated plants were same. There were very little karyotypic variations observed in case of both micropropagated and mother plants.

Published: October 2022

Summary

Introduction: Phyllanthus niruri L. (PnL) is a herbaceous plant containing flavonoid quercetin and can be used as an immunomodulator to prevent Covid-19. However, the flavonoid content and yield of herbs extract were not maximized. Therefore, PnL herbs were planted in various harvest periods and application of NPK-chitosan nanopolymer fertilizer to estimate these parameters.

Objectives: Determine the effect of NPK-chitosan nanopolymer fertilizer and harvesting age on herb extracts also determine the grouping pattern and correlation between responses based on FTIR-ATR spectral pattern using a chemometric approach.

Methods: Each group consisted of 50 plants. The formulation of NPK-chitosan nanopolymer fertilizer based on the dose of NPK consisting of the first dose is 15.5 grams/group, the second dose is 31 grams/group, and the third dose is 7.5 grams/group. Grouping of differences in harvesting age for plants consisted of 4, 6, and 8 weeks after the plant (WAP). Extraction used ultrasound-assisted extraction, and data were analyzed using a chemometric approach.

Results: Extract with the highest yield was found in second harvest time and third doses of fertilizer (W2D3) which is 9.73 %, and the highest TFC obtained in an extract with second harvest time and first doses of fertilizer (W2D1) is 17.34 mg QE/g. Total flavonoid content and extract yield were influenced by functional groups at wavenumbers 3486.77–3157.12 cm−1 (1); 1740.96–1670.34 cm-1 (3); 1425.02–1272.62 cm-1 (5); 1257,753–1138,81 cm−1 (6); 1131.38–945.53 cm-1 (7); 711.36–529.23 cm-1 (8).

Conclusions: The results showed that harvest time and fertilizer dose affected the growth parameters of PnL, total flavonoid content, and yield of extract. Functional groups in IR spectra also have positive and negative correlations with total flavonoid and yield extract responses.

Published: October 2022

Summary

Introduction: Common sage is cultivated in Europe and North America. It has strong antiviral, antibacterial and antifungal properties. This plant can be infected by different pathogenic fungi species, such as Alternaria alternata, Fusarium spp. (F. culmorum, F. equiseti, F. oxysporum), Phomopsis sclarea and Botrytis cinerea. Those species are the most frequently isolated fungi from sage stem base.

Objective: The aim of this study was to identify the causal agent of common sage wilt disease.

Methods: Studies were carried out in 2018–2020. 23 fungal isolates were identified based on their morphology and with use of PCR technique. Length and width of 100 conidia growing on SNA medium were measured after 7 days. Koch’s postulates were checked and the development of one fungus isolate (no. 13) was compared on seven media: the CMA, MEA, OA, PCA, SNA, PDA and Czapek medium. Sequences of the second largest subunit of RNA polymerase II (RPB2) were used to identify the pathogen.

Results: The fungus formed 3 kinds of spores: thin-walled, hyaline, slightly folded at the base, mostly 4-cell macroconidia, oblong, hyaline one- or two-cell microconidia and oval thick-walled chlamydospores. The Koch’s postulates were fulfilled. The fungus formed the most abundant aerial mycelium on the Czapek medium, and the least on the CMA medium. On the SNA medium, the mycelium grew into the medium and the aerial mycelium was not formed. The obtained RPB2 nucleotide sequence was 100% similar to the Fusarium oxysporum sequence deposited in GenBank (NCBI).

Conclusions: The results of this research can be used in further studies on the biological diversity of this species.

Published: October 2022

SummaryIntroduction:This paper presents the results of research about the antioxidant properties of extracts from 5 moss species, namelyBrachythecium rutabulum,Callicladium haldanianum,Hypnum cupressiforme,Orthodicranum montanumandPolytrichastrum formosum. The macerates of each above mentioned species in water and ethanol (50% and 96%) solutions were analysed.Objective:Total phenolic acids, total flavonoids and total flavonols concentrations and content of carotenoids was determined. Also some phenolic compounds were determined by HPLC.Methods:The 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities and the advanced oxidation protein products (AOPP) formation inhibition were studied.Results:The obtained results showed that the extracts prepared with 50% ethanol had the strongest radical scavenging activities. Every 50% ethanol extract also inhibited formation of AOPP. 96% ethanol extracts had the lowest free radical scavenging activities, althoughB. rutabulumextract strongly inhibited protein oxidation. Pearson’s correlation showed that the radical scavenging effects of water extracts and extracts prepared with 50% ethanol are dependent on the presence of phenolic acids and flavonoids.Conclusion:The results suggest the moss extracts as materials for potential use in pharmacy or cosmetology.
Analysis of the Concept of Disinformation from Peirce’s Semiotics
Authors: Ripoll Leonardo , Ohlson Márcia , Romanini Vinicius 
Published: October 2022

Abstract
Adopting the perspective of Peircean semiotics, the work proposes to analyze the concept of disin-formation based on the phenomenon of fake news and the “post-truth” neologism associated with it. We review some contemporary informational theories, which start from the relationship between communication, computing, society and technologies, to demonstrate the need to broaden the strictly analytical view of the concept of information, albeit grounded in cybernetics, to include the reflection of semiotics and pragmatism of Peirce. We will briefly present the foundations of semiotics, mainly in its relation to the concepts of beliefs and truth that form the framework of pragmatism. We propose, in particular, three complementary dimensions of the term disinformation based on some semiotic precepts that, in our view, allow a better understanding of its manifestation in the communicative processes present in social media.
“Dualismo digital” no ativismo contemporâneo: uma abordagem discursiva da #elenão
Authors: Costa Julia Lourenço 
Published: October 2022

Abstract
The main objective of this paper is to analyze, from a linguistic perspective and more specifically from discourse theories, the contemporary political claims that take place in the intense traffic between the internet and the urban space. The hashtag #elenão was selected as the place of observation, collection and analysis of the corpus, both for its relevance in the Brazilian context and for its functioning, which provides an understanding of the various manifestations of the corpus established between the utterance and the enunciation. We understand that the tension caused between online and offline, addressed by the language sciences based on the concept of “digital dualism”, can promote relevant theoretical and methodological, as well as political and social discussions.
The Continuum of Life on Facebook’s Virtual Memorials
Authors: Almeida Cândida 
Published: October 2022

Abstract
This article examines the semiotic implications of social media interactive processes established when Facebook profiles are memorialized following the user’s death. It also observes the communication processes that occur through the deceased’s contacts interactions with the virtual memorial page. It points to Facebook’s symbolic and systemic organization structure role in creating a specific comprehension of online and offline identities in the social media environment. The theoretical framework focuses on C. S. Peirce’s signs and semiosis studies to help understand the communication’s phenomenology revealed in this context as well as the process of continuity of the physical life through its symbolic representations on digital networks.
There is a group of political tweeters that nobody is studying: the detached
Authors: González-List Verónica 
Published: October 2022

Abstract
Through a review of the literature, the present article outlines the interaction forms that happen on Twitter when the participation is political, intending to show that the conversations made by the most significant collective on Twitter which is formed by ordinary users that post tweets 24/7 any given day with the sole intention to make public its political views, are invisible for the social studies. The actual political conversations attended by the social studies are related to parties, civic organizations, street manifestation, social activism, or some political manifestation that requires organization. The subject is important because these ordinary users with no agendas related to the formal or informal forms of political conversations known by the social studies form the biggest sector in the political social network par excellence, and no one is studying them. We propose the adjective ‘detached’ users to refer to these Twitter users.
Queering Bolsonaro’s mediatic discourse: Strengthening Brazilian LGBTQIA+ communities through language education
Authors: de Mello Ferraz Daniel , Miquelon Lucas Cardoso 
Published: October 2022

Abstract
Contemporary societies, especially some Western countries, have faced the return of neoconservatism, along with a desire for homogeneity, consensus, standardization, polarizations, and universalism in several social relations. With the election of alt-right, authoritarian, misogynist, and homophobe Jair Bolsonaro in 2018, many Brazilian citizens have faced a herculean challenge in relation to the maintenance of democracy and the provision of citizenship and critical education. The purpose of this paper is to problematize some media discourse produced by Bolsonaro and to investigate how such discourse has influenced the lives and education of our research participants (pre-service teachers). The first section investigates discourses and regimes of truth by explaining how discourses and ideologies influence our students’ lives and their future career. Section two points to the urgency of problematizing homophobic discourses, and section three queers Bolsonaro as an act of resistance.
Towards a systemic functional approach to context collapse
Authors: Farhat Theodoro C. 
Published: October 2022

Abstract
This paper presents an initial systemic functional interpretation of the nuclear features of the phenomenon known as “context collapse”, which occurs when multiple online audiences (such as family, friends and coworkers) are “flattened” into a single group of potential recipients. After introducing the fundamental systemic functional dimensions of stratification and instantiation, we briefly present Hasan’s systemic description of the contextual parameter of Tenor, which deals with the potential relations and roles enacted by the participants of an interaction. We propose that such a contextual system enables us to describe with theoretical precision the nuclear features of context collapse: besides one-way digital contact in Mode, the selection of [addressee: absent: category] in the system of TEXTUAL ROLES and a generalized vagueness in the system of SOCIAL ROLES. Finally, we outline two major strategies employed to circumvent it: enactment--based and activation-based.
Semiotic Boundary Spaces: An Exercise in Decolonial Aesthesis
Authors: Machado Irene 
Published: October 2022

AbstractThe main purpose of this essay is the analysis of the discourses expressed between Jaider Esbell’s Brazilian artistic sculptures and the monuments of the urban space. Based on J. Lotman’s notion of semiotic boundary space of culture, the analysis focuses on the controversial discursive relationships, such as intelligibility and unintelligibility; translation and untranslatability, and so on, observed from the historical tensioning of cultural languages. This analytical path leads us to intercultural relationships in which artistic languages in semiotic boundary spaces manifest the Aesthesis condition that has given the theoretical foundations for the Decolonial studies and the arising of a new episteme in the understanding of intercultural relationships. Thus, the semiotic concept of boundary space allows us to analyse various discursive relationships in historical-political contexts in the contemporary debate.
