Authors: Borinelli Benilson , Vitiello Sérgio Ricardo 
Published: October 2020

O controverso método de fracking para a extração de gás de xisto e seus impactos socioambientais têm colocado em evidência as disputas acirradas em torno das decisões políticas e do estado capitalista. Diante da relevância do tema e do incipiente número de estudos no Brasil, neste artigo, analisamos como as decisões sobre o frackingvêm sendo abordadas nas perspectivas funcionalista e crítica. Desenvolvemos uma pesquisa bibliográfica e descritiva, apoiados principalmente na literatura internacional. Embora as duas perspectivas ofereçam importantes contribuições, são as críticas que melhor capturam as relações de poder em jogo nas decisões sobre o frackinge fomentam o engajamento contra novas injustiças. Mais estudos serão necessários no País dada a complexidade do tema e da vigência de projetos pró-fracking que poderão ganhar força no atual contexto de desregulamentação neoliberal.Palavras-chave: Fracking.

Estado.“EXPLOSIVE” POLITIZATION OF SHALE GAS DECISIONS: critical contributions to fracking studyAbstractThe controversial fracking method for shale gas extraction and its socio-environmental impacts has brought to light disputes over political decisions and capitalist state. Given the theme's relevance and the incipient number of studies in Brazil, this article analyzes how decisions about fracking have been approached from functionalist and critical perspectives. We developed a bibliographic and descriptive research, supported mainly by international literature. While both perspectives make important contributions, critiques' ones can best capture the power relations at stake in decisions about fracking andfoster engagement against new injustices. Further studies will be needed in Brazil due to the theme complexity, the continuity of pro-fracking projects and the current intensification of neoliberal deregulation of environmental policies.Keywords: Fracking.

Authors: Poniam Budi 
Published: October 2020

According to TIMSS 2015 and PISA 2018 reports, Indonesian students’ knowledge and skills of mathematics are still far from adequate compare to other countries. Therefore the efforts to improve the condition need to done, not just by government but also educational institutions and movements. One of new movement is Gerakan Nasional Berantas Buta Matematika (GernasTastaka, 2018). This baseline study aims to describe and analysis the mathematical content knowledge of 100 elementary teachers from Lampung Utara regency that joined the workshop of mathematics teaching and learning which was developed and facilitated by team from Gernas Tastaka. The eight-question multiple choice pre-test covers Number and Operation, Measurement, Data Analysis, and Probability. Each question is related to specific mathematical content knowledge and skill that are supposed to be mastered by grade 6 students. The quantitative descriptive for each question was conducted to give more details on specific mathematical content knowledge. The result displays that only 36% of the participants can answer correctly 50% of the questions. The low competency of teachers gives impact to their students’ achievement. It is correspondent with the data from Indonesian National Assessment Program (INAP, 2012); mathematics competency of elementary students in Lampung province is below Indonesian national level. One of the teachers’ competencies is their mastery of content knowledge. This study recommends that future developmental workshops/ program for the participants must cover all mathematical content knowledge and skills of elementary level. Besides that, detailed data of participants should be provided in order to attain more reliable analysis.

Abstract
Coronavirus disease 2019 (COVID-19) has rapidly spread worldwide. Systematic analysis of lung cancer survivors at molecular and clinical levels is warranted to understand the disease course and clinical characteristics. We performed a retrospective study of 65 patients with COVID-19 from Wuhan Huoshenshan Hospital, of which 13 patients were diagnosed with lung cancer. Duringtreatment, lung cancer survivors infected with severe acute respiratory syndrome coronavirus 2 had a shorter median time from symptom onset to hospitalization (P=0.016) and longer clinical symptom remission time (P=0.020) than non-cancer individuals. No differences were observed among indicators such as time from symptom onset to hospitalization and symptom remission time between long-term and short-term survivors. The expression of ACE2(P=0.013) and TMPRSS2(P<0.001) was elevated in lung cancer survivors as compared with that in non-cancer individuals.

Abstract
Purpose: Plants are repository of important constituents with proven efficacy against many human diseases including viral diseases. The antiviral activity of many plants including Azadirachta indica, Xylopia aethiopica and Allium cepa has been reported. The novel coronavirus disease is no exception among viral diseases in which plant compounds could serve as potent antagonist. Therefore, our study investigated the inhibitory potentials of Azadirachta indica and Xylopia aethiopica isolates against SARS-CoV-2 viral accessory proteins and the host serine protease.Methods: The protein data (SARS-CoV-2 Papain like protease (PLpro) (PDB: 6wx4), Chymotrypsin-like main protease (3CLpro) (PDB:6YB7), SARS-CoV nsp 12 (PDB: 6nus), Host cell protease (TMPRSS1) (PDB:5ce1) were obtained from the Protein Data Bank (PDB), while the SDS format of each Ligands were obtained from Pubchem database. Molecular docking analysis was performed with Auto Dock Vina 1.5.6 and visualization of the interaction between the ligands and protein was done with discovery studio 2019. The ADMET prediction of pharmacokinetics and toxicity properties of the ligands was obtained using vNN Web Server.Results: Our result showed that all the plant isolates demonstrated negative Gibb’s free energy, indicating good binding affinity for both the viral and host protein. Overall, twenty-three of the forty-seven isolates showed good binding affinity comparable with dexamethasone that was used as reference drug. Although many of the compounds have good binding affinity for the viral and host proteins, based on the ADMET prediction, only Azadironic acid, Nimbionone, Nimbionol and Nimocinol all from A. indica could serve as potential drug candidate with good pharmacokinetics and toxicity profile. Conclusion: This study provides an insight into potential inhibitors and novel drug candidates for SARS-CoV-2.

Abstract
Background: Tubulointerstitial fibrosis (TIF) is one of the main pathological features of various progressive renal damages and chronic kidney diseases. Mesenchymal stromal cells (MSCs) have been verified with significant improvement in the therapy of fibrosis diseases, but the mechanism is still unclear. We attempted to explore the new mechanism and therapeutic target of MSCs against renal fibrosis based on renal proteomics.Methods: TIF model was induced by adenine gavage. Bone marrow derived MSCs was injected by tail vein after modeling. Fibrosis biomarkers or extracellular matrix proteins and histopathological change were assessed by Masson staining, Sirius red staining, immunohistochemistry, and western blot. Renal proteomics was analyzed using iTRAQ-based mass spectrometry.Results: MSCs treatment clearly decreased the expression of α-SMA, collagen type I, II, III, TGF-β1, p-Smad2/3, IL-6, IL-1β, and TNFα compared with model rats, while p38 MAPK increased. 6,213 proteins were identified, but only 40 proteins exhibited significant differences (30 upregulated, 10 downregulated) compared MSCs group with the model group. Bioinformatics analysis revealed that these proteins play important roles in the proliferation, inflammatory and immune responses, apoptosis, phagosome, etc. According to literatures and bioinformatics analysis, the most markedly downregulated protein, galectin3, was further assessed by quantitative PCR and western blot in renal tissues. Galectin3 levels were downregulated in adenine-induced renal tissues and TGF-β1 induced tubular epithelial cells and interstitial fibroblasts in consistent with iTRAQ after MSCs treatment.Conclusion: The founds suggest that galectin3 maybe involves in the antifibrotic mechanisms of MSCs therapy for tubulointerstitial fibrosis as well as a possible therapeutic target.
