A partir da década de 2000, o Estado brasileiro criou assentamentos denominados Projetos de Desenvolvimento Sustentável (PDS). No estado de São Paulo, estes PDS estão em grande parte localizados em regiões metropolitanas. Neste contexto, buscamos examinar o papel da agricultura na estratégia de vida das famílias pluriativas do assentamento periurbano Milton Santos. Para tal intuito, levantamos elementos de contextualização do assentamento, de caracterização das famílias pluriativas, de suas estratégias e de suas práticas agrícolas, além de considerarmos indicadores de renda familiar. Constatamos que a atividade agrícola desempenha papel multifuncional, possibilitando notadamente aos assentados com poucas chances de inserção no mercado de trabalho a realização de atividades produtivas geradoras de renda, contribuindo para uma perspectiva de desenvolvimento sustentável. Palavras chaves: Projeto de Desenvolvimento Sustentável, assentamentos periurbanos, pluriatividade, reforma agrária, multifuncionalidade da agricultura.
O PARADIGMA ORIGINÁRIO DA EDUCAÇÃO DO CAMPO E A DISPUTA DE TERRITÓRIOS MATERIAIS/IMATERIAIS COM O AGRONEGÓCIO/ The paradigm originating in the countryside education and the dispute of material/immaterial territories with the agribusiness/ El paradigma originario en la educación del campo y la disputa de territorios materiales/inmateriales con el agronegocio

A territorialização da Educação do Campo é produto e, concomitantemente, instrumento da luta dos movimentos socioterritoriais camponeses. A Educação do Campo se desenvolve, simultaneamente, à intensificação das disputas territoriais no campo. É a conquista e a resistência dos/nos territórios camponeses permitindo a criação e a reprodução da Educação do Campo. A territorialização da Educação do Campo se origina no conflito/ disputa com a territorialização do capital monopolista no campo (agronegócio). Por isso, o Paradigma Originário da Educação do Campo é, necessariamente, um projeto de oposição ao agronegócio que reflete a luta de classes no campo. Nosso objetivo é demonstrar, sobretudo, por meio das narrativas dos educandos do Curso Especial de Graduação em Geografia (CEGeo), que esta experiência de Educação do Campo, foi, na prática, instrumento do campesinato de resistência ao capital.
CONFLITUALIDADE E QUESTÃO AGRÁRIA: OS MODELOS DE DESENVOLVIMENTO PARA O ESPAÇO AGRÁRIO LATINO-AMERICANO/ Conflictiveness and agrarian question: development models for the Latin American agrarian space/ Conflictualidad y cuestión agraria: modelos de desarrollo para el espacio agrario latinoamericano

A questão agrária é multidimensional, multiescalar e envolve tanto momentos de conflito, bem como de conflitualidade. A questão agrária também está inserida no debate paradigmático – Paradigma da Questão Agrária e Paradigma do Capitalismo Agrário – em que ambos propõem modelos de desenvolvimento para o espaço agrário. Desde a década de 1990, o espaço agrário latino-americano é alvo da expansão de políticas neoliberais que incentivam o agronegócio pautado na produção de commodities para a exportação. Ao mesmo tempo, o campesinato e demais povos tradicionais da América Latina se organizam em movimentos socioterritoriais e promovem práticas de desenvolvimento contra-hegemônicas, ordenadas pela reforma agrária popular, agroecologia, soberania alimentar, educação do campo, entre outros. Estes modelos de desenvolvimento estão em conflito e em permanente conflitualidade, conformando o espaço agrária latino-americano.

O artigo veicula uma análise socioeconômica de assentamentos rurais no Extremo Sul da Bahia e no Pontal do Paranapanema, com foco na agrobiodiversidade associada à mandioca. Entrevistas semiestruturadas foram conduzidas com 15 agricultores em 10 assentamentos na Bahia e 11 agricultores em 7 assentamentos em São Paulo. Os índices socioeconômicos destas regiões estão entre os mais baixos de seus respectivos estados, com maior vulnerabilidade na Bahia. Cerca de 60% dos filhos dos agricultores no Pontal residem nos assentamentos, dos quais dois terços trabalham na agricultura. Na Bahia, 20% dos filhos estão no assentamento, dos quais 75% atuam em atividades agrícolas. Com população mais idosa, os assentamentos da Bahia apresentam maior diversidade de mandioca, cuja produção abastece as casas de farinha artesanais. As dinâmicas culturais em torno das atividades da produção de farinha nos assentamentos constituem um elemento-chave na manutenção da agrobiodiversidade regional. A produção de mandioca no Pontal, por outro lado, atende à demanda de fecularias industriais fora dos assentamentos, o que estimula o cultivo de poucas variedades que atendem o padrão das indústrias. O alinhamento à agroecologia nos assentamentos da região baiana tem sido fundamental para a valorização da diversidade agrícola, enquanto o alinhamento à agricultura industrial na região paulista enfraquece a diversidade agrícola e as estruturais socioculturais de manutenção da agrobiodiversidade.

O objetivo deste trabalho é debater os desafios e contradições gerados pela inserção da educação em agroecologia na universidade brasileira. Para tanto foi desenvolvido um estudo de caso de duas importantes graduações em agroecologia inicialmente implantadas em universidades públicas em nosso país. Foram realizadas entrevistas semiestruturadas com professores responsáveis pela construção dos cursos, assim como a análise documental dos Projetos Políticos Pedagógicos dos mesmos. Os resultados da pesquisa apresentados neste ensaio revelam que a inserção da agroecologia nas universidades estudadas gerou e tem gerado tensionamentos que estão presentes nas instituições de ensino superior como um todo. No estudo o conflito se revelou pela tendência dominante em adaptar as formações à lógica de mercado, por meio do modelo de ensino tecnicista e empreendedor predominante nas ciências agrárias. Em contra-hegemonia a esta tendência, a educação em agroecologia estrutura uma proposta de formação mais humana e crítica para dentro da universidade, com projetos de curso que enfrentam o modelo dominante e tem o desafio de produzir conhecimento e formar profissionais necessários à transição agroecológica dos sistemas produtivos.

La exclusión política y los mecanismos de marginalidad como soporte de la organización y consolidación del Estado Nación Argentino. Un recorrido en clave historiográfica
Authors: Stefanelli Emanuel 
Published: March 2021

Este ensayo tiene por objetivo reflexionar acerca de los procesos de exclusión política, sus destinatarios y los fundamentos esgrimidos para explicar los mecanismos de marginalidad que darán sustento a la organización (1852-1880) y consolidación (1880-1955) del Estado Argentino. La intención es analizar y comprender las múltiples formas de exclusión sobre las que se amparan los procesos clasificatorios de fines del siglo XIX y principios del siglo XX. Se pretende mostrar entonces cómo la imposición coercitiva de una lógica de inclusión excluyente permitió forjar el proyecto hegemónico de las elites dirigentes. La inclusión y proliferación de estudios recientes sobre esta temática brindan nuevas claves para analizar, desde el campo de las ciencias sociales, las tensiones subyacentes a la relación entre Estado y sociedad civil en las diferentes coyunturas histórico-políticas de nuestro país. La reflexión final pretende recuperar las reformulaciones atribuidas al concepto de exclusión y los desafíos que hoy enfrentan los regímenes democráticos respecto de las nuevas condiciones sociales introducidas por el mundo globalizado.
Lacan
Authors: De Beistegui Miguel 
Published: March 2021

Lacan: A Genealogy provides a genealogical account of Lacan’s work as a whole, from his early writings on paranoid psychosis to his later work on the real and surplus enjoyment.
Beistegui argues that Lacan's work requires an in-depth genealogy to chart and interpret the his key concept of desire. The genealogy is both a historical and critical approach, inspired by Foucault, which consists in asking how – that is, by what theoretical and practical transformations, by the emergence of which discourses of truth, which institutions, and which power relations – our current subjectivity was shaped. Desire is a crucial thread throughout because it lies at the heart not only of liberal political economy, psychiatry and psychopathology, and the various discourses of recognition (from philosophy to psychology and the law) that shape our current politics of identity, but also, and more importantly, of the manner in which we understand, experience and indeed govern ourselves, ethically and politically.
A novel reading of Lacan that foregrounds the radicality and urgency of his concepts and the relationship between desire, norm and the law.
The Duel in European History
Authors: Kiernan Victor , Blackbourn David 
Published: March 2021

For centuries, duelling played an integral role in the preservation of the aristocratic order in Europe, defying attempts by both church and state to ban the practice. Moreover, the romance and drama of the duel has made it an enduring fixture in films, literature, and the theatre.
In The Duel in European History, renowned historian Victor Kiernan writes with his characteristic wit and insight of duelling's evolution from its medieval origins – when it was regarded as a badge of rank - to the early twentieth century, by which time it was seen as an irrational anachronism. In doing so, he shows how the duelling tradition was something unique to Europe and its colonies, and, in its contribution to the development of the officer corps, played a key part in shaping European military power.
Drawing on a vast range of historical and cultural sources, this is the definitive account of a violent ritual that continues to fascinate even today.
The Battle of the Ayatollahs in Iran
Authors: Vatanka Alex 
Published: March 2021

Understanding the foreign policy agenda and behavior of the Islamic Republic of Iran is a critical challenge for the world. But where do the principal Iranian regime actors come from in terms of political background, experiences and interests? Which types of ambitions or policy conflicts have dominated and shaped foreign policy debates since 1979?
This book explains the internal policy process in Tehran by following two regime personalities, Ali Khamenei, the Supreme Leader, and Akbar Hashemi Rafsanjani, who before his death in January 2017 held some of the most powerful political positions in Iran. No two men have been more influential in dictating the regime’s decision-making processes since 1979. Yet little is known about how their competing worldviews and interests, their key moments of dispute – both personal or policy-based – or their personal ambitions have informed the trajectory of Iranian politics. The book analyzes Khamenei and Rafsanjani’s own words and writings - and accounts of them given by others - to reveal how the domestic policy contest has shaped Tehran’s actions on the regional and international stage. Comprising primary and secondary Iranian sources - including untapped memoirs, newspaper reports, and Iranian electronic media and personal interviews - the book highlights the principal rivalries over the lifespan of the Islamic Republic and offers new insights into the present and future of Iranian foreign policy.

IntroductionThe development and progression of hepatocellular carcinoma (HCC) is a multistage process involving the deregulation of genes that are crucial to cellular processes. Multiple risk factors are correlated with HCC. MicroRNA is differentially expressed in development of different types of malignancies, including hepatic malignancy. Single nucleotide polymorphisms (SNPs) are the most common sequence variation in human genome. SNPs in miRNAs may affect transcription, processing or target recognition and result in malignant diseases.
Aim: To determine the association between micro-RNA gene polymorphisms and development of HCC in Egyptian Patients.Material and methodsThis study included 200 individual who were matched in age and sex. Tumor staging was done using BCLC staging system. Quantification and genotyping of Micro-RNA were performed.ResultsAmong the 200 patients, 2 groups were described: group I included 90 HCC patients with a male majority (72.2%) and 110 controls in group II. Diabetes and hypertension were detected as risk factors. Three microRNA SNPs were assayed. There was a significant association between rs10061133 miR-499b and the risk of HCC. The genotypes GG or G allele were associated significantly to an increased risk of HCC (GG: OR (95% CI) = 2.91 (1.23-4.22), p = 0.013; G allele: OR (95% CI) = 1.79 (1.12- 2.15), p = 0.026) compared with the genotype of AA or AG or A allele.ConclusionsThere is an association between the mi-RNA SNPs and the susceptibility to HCC, aiming to explore some roles and mechanisms of SNPs within miRNAs in the occurrence and development of HCC.

IntroductionObjectiv. To investigate the contribution of TERT rs2736100 and rs2853669 gene polymorphisms in defining the genetic predisposition to AML, their association with different prognostic markers and their impact on survival, outcome and the prognosis of affected patients. Also, we investigated the association of TERT SNPs in AML in the presence or absence of DNMT3A (R882), NPM1 and FLT3 mutations.Material and methodsA total of 509 participants were enrolled in our study, consisting of 146 AML patients and 363 healthy participants, with no history of malignancy. TERT rs2736100 and rs2853669 polymorphisms were genotyped by using TaqMan SNP genotyping assays FLT3 (ITD, D835), DNMT3A (R882) and NPM1 c.863_864insTCTG (type A) mutation status was analyzed in each AML case.ResultsTERT rs2736100 and rs2853669 were not associated with AML risk in the codominant, dominant, recessive or allelic models. Multivariate Cox regression showed that TERT rs2853669 was a significant predictor for overall survival in AML patients. After adjusting for age, gender, cytogenetic risk group, ECOG status, FTLT3, DNM3A or NMP1 mutation, AML subtype and treatment, the estimated adjusted hasard ratio (HR adjusted=1.54, 95%CI:[1.01;2.35]) showed that the TERT rs2853669 variant genotype had a negative influence on survival time.ConclusionsTERT rs2853669 and rs2736100 polymorphisms were not risk factors for developing AML in the Romanian population, but TERT rs2853669 variant genotype had a negative effect on AML patients overall survival in the presence of other known prognostic factors.
Effect of N-acetyl-cysteine in Prevention of Noise-Induced Hearing Loss: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Authors: Chang Po-Hsiung , Liu Chia-Wei , Hung Shih-Han , Kang Yi-No 
Published: March 2021

IntroductionNoise-induced hearing loss is one of the most prevalent causes of hearing impairment and occupational diseases. Although multiple factors lead to noise-induced hearing loss, prevention and protection strategies remain limited. Studies in the past decade have employed antioxidants, especially N-acetyl-cysteine, to prevent noise-induced hearing loss. Therefore, this systematic review and meta-analysis of randomized controlled trials evaluated the effect of N-acetyl-cysteine on the prevention of noise-induced hearing loss.Material and methodsThis systematic review and meta-analysis included relevant studies from the Cochrane Library, EMBASE, PubMed, ScienceDirect, Scopus, and Web of Science by using related terms. The study only included randomized controlled trials in meta-analyses and assessed the quality of the identified randomized controlled trials by using the Cochrane Risk of Bias tool. Two authors extracted and calculated data on characteristics and hearing threshold. The results are presented as weighted mean difference (WMD) with 95% confidence interval (CI).ResultsThis study identified five randomized controlled trials that randomized 1,115 patients into N-acetyl-cysteine and control groups. The meta-analysis evidenced that N-acetyl-cysteine has greater protective effects against hearing threshold shifts than the control in the 0 to 4 kHz (WMD = −3.39, 95% CI: −6.56 to −0.22) and 0 to 6 kHz (MD = −3.49, 95% CI: −6.57 to −0.41) subgroups.ConclusionsThe present review and meta-analysis recommends that N-acetyl-cysteine may be considered as an option for protective therapy for noise-induced hearing loss. Nonetheless, larger randomized controlled trials are requisite for further investigation and verification.

IntroductionChemokines play a crucial role in tumor growth and progression according to proangiogenic and immunosuppressive acting. This study was aimed to investigate the serum levels of selected chemokines in patients with ovarian cancer or benign ovarian tumors to point on their role in tumorigenesis and their potential use in preoperative diagnosing of adnexal mass.Material and methodsThe study group consisted of 59 women with ovarian cancer: 17 epithelial ovarian cancer (EOC) patients and 42 women with benign ovarian tumors. We measured in sera obtained preoperatively the level of CA125 and the panel of 5 chemokines: CX3CL1/Fractalkine, CXCL1/GRO-α, CXCL12/SDF-1, CCL20/MIP-3α and IL-17F, using chemiluminescence method with multiplexed bead based immunoassay.ResultsCX3CL1 was significantly elevated in sera of advanced ovarian cancer patients compared to women with benign ovarian tumors. The significant elevation of CXCL1 was also observed (both: early and advanced stage). The similar pattern was present with standard ovarian cancer marker – CA125. In our patients with endometriotic cysts CA125 levels were significantly higher than in women with other benign tumors whereas all analyzed chemokines had similar serum titers in patients with endometriotic vs other benign ovarian cysts.ConclusionsCX3CL1 and CXCL1 are elevated in sera of EOC patients what points on their role in cancer development. Moreover, they might be useful in preoperative differential diagnosis of ovarian tumors, especially as they were not elevated in cases of endometriosis.
Gender-specific differences in plasma ferritin in adolescents smoking cigarettes versus waterpipe smoking: the Irbid-TRY Project

Published: March 2021

IntroductionFerritin has been implicated in body physiology and pathology. Smoking cigarettes (Cg) alters ferritin metabolism. Waterpipe (Wp) smoking has recently reemerged as a global epidemic and is linked to the most devastating diseases. However, the effect of smoking Wp on ferritin is not known. Therefore, the current study compared plasma ferritin in adolescents smoking Cg, Wp, both (CgWp) versus never smoked.Material and methodsSelf-reported smoking status and plasma ferritin levels were obtained from 849 boys (n = 470) and girls (n = 379) in the 7th–10th grade (age range = 13–17 years).ResultsThe ANCOVA revealed a main effect for gender (p < 0.000) and smoking status (p < 0.02) without an interaction effect (p > 0.9). Post-hoc analysis showed greater plasma ferritin in the adolescents smoking Wp (p < 0.03) and CgWp (p < 0.004) versus never smoked. Gender-stratified ANCOVA showed a main effect for smoking status in the boys (p < 0.02) and girls (p < 0.03). Additional comparisons among the boys showed greater plasma ferritin in the Wp (p < 0.006) and CgWp (p < 0.008) smoking groups versus never smoking, without differences (p > 0.5) between Wp and CgWp smoking. Another subgroup comparison showed greater plasma ferritin in the girls smoking Cg (p < 0.02) and CgWp (p < 0.02) versus never smoking, without a difference (p > 0.3) between Cg and CgWp smoking.ConclusionsThe results indicate that ferritin is elevated in adolescent smokers, particularly the boys smoking Wp and CgWp and in the girls smoking Cg and CgWp.
