MONTE SIÃO EXTREMIDADE DO SAFON: Estudo da influência da mitologia cananéia na Teologia de Sião a partir da análise exegética do Salmo 48

A Teologia de Sião expressa pela tradição dos filhos de Corá é de certa forma curiosa. É implicante admitir a idéia de uma influência cananeia na Teologia de Sião. Não há como negar esse fato, pois o Salmo 48 parece realmente possuir esta influência. É uma influência cananeia e também das tradições do Sul judaíta. Esta pesquisa tem por objetivo analisar tal teologia de Sião existente em Jerusalém e apresentada no Salmo 48. Isto para chegar a uma resposta acerca da influência que os filhos de Corá podem ter sofrido da religião cananeia, ao utilizar elementos dos mitos cananeus na composição do Salmo 48 e de outros salmos de sua coleção. Termos como Safon, mar, morte, Monte Sião e outros, e conceitos como mitologia, montanha sagrada, extremidade do mundo, Olimpo, etc, fazem pensar que eles de fato queriam sobrepor os mitos cananeus apresentando uma nova leitura, a partir da fé em Javé. Os filhos de Corá possuíam tradição do Norte israelita. As cidades onde eles habitaram estavam situadas em Efraim, Manassés e Dã. Algumas cidades de Manassés e Efraim eram cananeias. Os reis do Norte eram em sua maioria promotores da religião cananeia. Este era o ambiente onde os filhos de Corá habitaram e cumpriram seu ministério levítico.

RELIGIÃO E MST: ESTUDO DOS BATISTAS DA CONGREGAÇÃO MONTE SIÃO NO ASSENTAMENTO ANTONIO CONSELHEIRO II NA REGIÃO DO PONTAL DO PARANAPANEMA

A inserção de uma igreja evangélica em um assentamento rural do Movimento dos Trabalhadores Rurais Sem-terra (MST), é objeto de nosso estudo de caso neste presente trabalho. A dissertação pesquisa e analisa a inserção dos evangélicos batistas no assentamento Antonio Conselheiro II na região do Pontal do Paranapanema, no estado de São Paulo, assim como a conseqüente implantação neste da Congregação Batista Monte Sião . Partindo de uma perspectiva teórica e empírica, o objetivo concentra-se em analisar a experiência de vida dos assentados batistas no interior do assentamento, buscando retratar as formas, tanto conceptuais como práticas, que estes vivenciam sua fé, costumes e crenças, sonhos e ideais, sempre procurando tecer relações que nos permitam melhor avaliar a forma como os mesmos compreendiam e comunicavam sua fé enquanto assentados do MST. Da apreciação crítica dos relatos obtidos nas entrevistas e dos dados do questionário, ambos aplicados aos agentes de nossa pesquisa, surge uma história que nos desvela faces de uma relação identitária que mescla ideologia e fé, ser evangélico batista e assentado no MST, bem como uma proposição internalizada de uma metodologia da não-violência nas manifestações do movimento Sem-terra.(AU)

Transporte de nano SiO₂ por migración a través de materiales cementantes

Uno de los nanos materiales más investigados actualmente es la nano-sílice, la cual ha despertado el interés de muchos investigadores debido a que está aportando grandes beneficios a los materiales base cemento. La nano-sílice ha demostrado que mejora las propiedades de los materiales cementantes tanto en estado fresco como en endurecido. Puede modificar las propiedades reológicas o la trabajabilidad en estado fresco, así como la resistencia a la compresión y la porosidad de las estructuras después de la etapa de endurecimiento. Es por esto que estas nano-partículas representan la oportunidad de realizar importantes avances que permitan optimizar el uso de los recursos actuales y el aprovechamiento de los materiales cementantes. En este trabajo, se está estudiando la posibilidad de utilizar la nano-sílice como un tratamiento superficial que ayude a disminuir el impacto del medio ambiente en estructuras en servicio que puedan presentar un cierto deterioro. Se analiza la utilización de nano-partículas en concreto en estado endurecido con el fin de mejorar su desempeño y sus aspectos de durabilidad. Por medio del método de migración electroquímica, basado en el transporte de partículas con cierta carga bajo la acción de un campo eléctrico, se favorece la penetración de nano-partículas de sílice hacia el interior de un mortero de cemento Portland desde una cara expuesta a una solución coloidal. Las partículas se mueven por acción del campo eléctrico hacia el ánodo situado en la cara opuesta de la probeta de mortero, dando lugar a una interacción química con la microestructura de la matriz cementante. Se ha observado que las partículas de sílice en esta solución coloidal empiezan a aglomerarse después de cierto periodo de tiempo y solidifican sobre la superficie expuesta de la probeta de mortero. Este material sólido ocasiona que la cantidad de corriente que circula por el circuito disminuya y por consiguiente baje la efectividad del mismo, ya que las partículas con carga eléctrica se mueven con mayor dificultad en medios solidos que en líquidos. Se encontró que la incorporación de nano-partículas de sílice a la matriz de mortero endurecido puede afectar el desempeño de una manera positiva frente a la penetración de cloruros, carbonatación y absorción de agua por capilaridad. De acuerdo a las respuestas eléctricas durante el tratamiento, se encontró que la resistencia eléctrica de las probetas aumenta, lo cual puede relacionarse con la modificación del sistema poroso debido al efecto filler de las nano-partículas; es decir, al refinar los poros, las cargas eléctricas encuentran menos espacio para moverse. Además las nano-partículas afectan químicamente a las fases de la pasta del cemento, ya que se encontró por microscopia electrónica de barrido que a una distancia entre 1.5 y 2 mm, aparecen aglomerados que enriquecen de silicio a las fases de la matriz del mortero y en otros casos, la migración cambia totalmente la apariencia del mortero y ocasiona valores de relaciones Ca/Si muy por debajo de los valores convencionales registrados en la literatura, con lo que es posible pensar que puede existir una actividad puzzolanica.

Inmovilización de lacasas en esferas de SiO₂ para la degradación de rojo congo

Propósito y Método de Estudio: Las lacasas son enzimas extracelulares que tienen la capacidad de oxidar una amplia variedad de sustratos utilizando al oxígeno como aceptor de electrones. Debido a esto, se ha utilizado esta enzima para diversas aplicaciones biotecnológicas dentro de las cuales destaca la degradación de colorantes textiles. En este trabajo se inmovilizaron tres tipos de lacasas, dos a partir de hongos de pudrición blanca (lacasa-HPB y lacasa HTT) y una comercial del género Trametes versicolor (lacasa-EC), en esferas mesoporosas de dióxido de silicio modificado para la degradación del colorante tipo azo rojo congo y azul índigo. Las lacasas HPB y HTT fueron purificadas a partir de la fermentación líquida optimizada de los hongos de pudrición blanca. Posteriormente se inmovilizaron mediante enlace covalente con el soporte (SiO2) y se realizaron las cinéticas de actividad enzimática y de degradación de los colorantes rojo congo y azul índigo. Contribuciones y Conclusiones: Se encontraron las condiciones de máxima producción de lacasa para los hongos seleccionado (HPB) y el hongo de referencia (HTT), observando que la producción de las lacasas se ve favorecida cuando el medio de cultivo contiene materiales ligninocelulósicos. Además se purificaron lacasas a partir de los extractos de los hongos HPB y HTT obteniendo pesos molecuares de aproximadamente 67 kDa lo que concuerda con lo reportado para las lacasas monoméricas. Se inmovilizaron las lacasas-EC, lacasas-HPB y lacasas-HTT en esferas mesoporosas de dióxido de silicio reteniendo un 56.94%, 55.68% y 46.08% de su actividad inicial respectivamente. En la degradación del colorante rojo congo con las enzimas inmovilizadas se obtuvieron porcentajes de decoloración de un 92.2%, 61.9% y 42.2% para la lacasa-EC, lacasa-HPB y lacasa-HTT en un tiempo de 60 minutos. Para el colorante azul índigo los porcentajes de degradación fueron de 89.2%, 62.1% y 50.3% para la lacasa-EC, lacasa-HPB y lacasa-HTT en 90 minutos. Por los resultados anteriores se muestra que la inmovilización enzimática de lacasas en SiO2 mesoporoso modificado con aminas, es una opción recomendable en el tratamiento de efluentes textiles, ya que los porcentajes de degradación se favorecen por el aporte que presenta el soporte en la degradación debido a la adsorción del colorante, disminuyendo por lo tanto los tiempos de proceso de tratamiento de efluentes acuosos con colorantes.

Projeto de intervenção de diabetes mellitus na comunidade da UBS "Francisco de Assis". Monte Sião - Minas Gerais

O diabetes mellitus tipo 2 (DM2) é uma doença crônica frequente e sua prevalência vem aumentando rápida e continuamente nas últimas décadas em todo o mundo, adquirindo características epidêmicas em vários países, particularmente naqueles em desenvolvimento. Segundo a Organização Pan-americana da Saúde (OPAS), existe epidemia dessa doença em curso. Em 1985, eram 30 milhões de pacientes no mundo todo; em 2000 foram notificados 177 milhões de casos, devendo esse número aumentar para 370 milhões até 2030. De acordo com o Estudo Multicêntrico sobre a Prevalência de Diabetes no Brasil, realizado em 1988, 7,6% da população adulta do país tem esse problema de saúde. Além disso, as estatísticas oficiais de morbimortalidade apontam que o DM2 constitui a quinta indicação de hospitalização no Brasil e está entre as dez maiores causas de mortalidade no país. Diante desses resultados, há grande preocupação que surge é o como enfrentar essa situação nos diferentes segmentos da sociedade. O envelhecimento populacional e as alterações do estilo de vida são apontados como os principais determinantes do acentuado incremento na frequência de DM2, nos últimos anos.Evidências quanto às alterações no estilo de vida como alimentação não saudável e a falta de atividades físicas regulares, associadas ao aumento da expectativa de vida dos brasileiros têm sido apontados como responsáveis pela prevalência crescente do DM2 no país.O objetivo do projeto é estimular mudanças de estilos de vida para atuar sob as principais causas da prevalência de Diabetes Mellitus na área da equipe de saúde da UBS Dr. "Francisco de Assis" do município Monte Sião mediante atividades educativas que consistiram em realização de palestras, clube debate, videoconferências; dinâmica de grupo; exibição de vídeos e pôster.O nosso universo será 116 pacientes diabéticos cadastrados e aportaremos novos conhecimentos aos usuários, além das complicações que leva não ter os cuidados para obter uma melhor qualidade de vida

An Asp49 Phospholipase A2 From Snake Venom Induces Cyclooxygenase-2 Expression And Prostaglandin E2 Production Via Activation Of Nf-κb, P38mapk, And Pkc In Macrophages.

Phospholipases A2 (PLA2) are key enzymes for production of lipid mediators. We previously demonstrated that a snake venom sPLA2 named MT-III leads to prostaglandin (PG)E2 biosynthesis in macrophages by inducing the expression of cyclooxygenase-2 (COX-2). Herein, we explored the molecular mechanisms and signaling pathways leading to these MT-III-induced effects. Results demonstrated that MT-III induced activation of the transcription factor NF-κB in isolated macrophages. By using NF-κB selective inhibitors, the involvement of this factor in MT-III-induced COX-2 expression and PGE2 production was demonstrated. Moreover, MT-III-induced COX-2 protein expression and PGE2 release were attenuated by pretreatment of macrophages with SB202190, and Ly294002, and H-7-dihydro compounds, indicating the involvement of p38MAPK, PI3K, and PKC pathways, respectively. Consistent with this, MT-III triggered early phosphorylation of p38MAPK, PI3K, and PKC. Furthermore, SB202190, H-7-dihydro, but not Ly294002 treatment, abrogated activation of NF-κB induced by MT-III. Altogether, these results show for the first time that the induction of COX-2 protein expression and PGE2 release, which occur via NF-κB activation induced by the sPLA2-MT-III in macrophages, are modulated by p38MAPK and PKC, but not by PI3K signaling proteins.

Prognostic Value Of Dna And Mrna E6/e7 Of Human Papillomavirus In The Evolution Of Cervical Intraepithelial Neoplasia Grade 2.

This study aimed at evaluating whether human papillomavirus (HPV) groups and E6/E7 mRNA of HPV 16, 18, 31, 33, and 45 are prognostic of cervical intraepithelial neoplasia (CIN) 2 outcome in women with a cervical smear showing a low-grade squamous intraepithelial lesion (LSIL). This cohort study included women with biopsy-confirmed CIN 2 who were followed up for 12 months, with cervical smear and colposcopy performed every three months. Women with a negative or low-risk HPV status showed 100% CIN 2 regression. The CIN 2 regression rates at the 12-month follow-up were 69.4% for women with alpha-9 HPV versus 91.7% for other HPV species or HPV-negative status (P < 0.05). For women with HPV 16, the CIN 2 regression rate at the 12-month follow-up was 61.4% versus 89.5% for other HPV types or HPV-negative status (P < 0.05). The CIN 2 regression rate was 68.3% for women who tested positive for HPV E6/E7 mRNA versus 82.0% for the negative results, but this difference was not statistically significant. The expectant management for women with biopsy-confirmed CIN 2 and previous cytological tests showing LSIL exhibited a very high rate of spontaneous regression. HPV 16 is associated with a higher CIN 2 progression rate than other HPV infections. HPV E6/E7 mRNA is not a prognostic marker of the CIN 2 clinical outcome, although this analysis cannot be considered conclusive. Given the small sample size, this study could be considered a pilot for future larger studies on the role of predictive markers of CIN 2 evolution.

Solid Lipid Nanoparticles For Hydrophilic Biotech Drugs: Optimization And Cell Viability Studies (caco-2 & Hepg-2 Cell Lines).

Insulin was used as model protein to developed innovative Solid Lipid Nanoparticles (SLNs) for the delivery of hydrophilic biotech drugs, with potential use in medicinal chemistry. SLNs were prepared by double emulsion with the purpose of promoting stability and enhancing the protein bioavailability. Softisan(®)100 was selected as solid lipid matrix. The surfactants (Tween(®)80, Span(®)80 and Lipoid(®)S75) and insulin were chosen applying a 2(2) factorial design with triplicate of central point, evaluating the influence of dependents variables as polydispersity index (PI), mean particle size (z-AVE), zeta potential (ZP) and encapsulation efficiency (EE) by factorial design using the ANOVA test. Therefore, thermodynamic stability, polymorphism and matrix crystallinity were checked by Differential Scanning Calorimetry (DSC) and Wide Angle X-ray Diffraction (WAXD), whereas the effect of toxicity of SLNs was check in HepG2 and Caco-2 cells. Results showed a mean particle size (z-AVE) width between 294.6 nm and 627.0 nm, a PI in the range of 0.425-0.750, ZP about -3 mV, and the EE between 38.39% and 81.20%. After tempering the bulk lipid (mimicking the end process of production), the lipid showed amorphous characteristics, with a melting point of ca. 30 °C. The toxicity of SLNs was evaluated in two distinct cell lines (HEPG-2 and Caco-2), showing to be dependent on the concentration of particles in HEPG-2 cells, while no toxicity in was reported in Caco-2 cells. SLNs were stable for 24 h in in vitro human serum albumin (HSA) solution. The resulting SLNs fabricated by double emulsion may provide a promising approach for administration of protein therapeutics and antigens.

Microbial Evaluation Of Traumatized Teeth Treated With Triple Antibiotic Paste Or Calcium Hydroxide With 2% Chlorhexidine Gel In Pulp Revascularization.

Revascularization outcome depends on microbial elimination because apical repair will not happen in the presence of infected tissues. This study evaluated the microbial composition of traumatized immature teeth and assessed their reduction during different stages of the revascularization procedures performed with 2 intracanal medicaments. Fifteen patients (7-17 years old) with immature teeth were submitted to the revascularization procedures; they were divided into 2 groups according to the intracanal medicament used: TAP group (n = 7), medicated with a triple antibiotic paste, and CHP group (n = 8), dressed with calcium hydroxide + 2% chlorhexidine gel. Samples were taken before any treatment (S1), after irrigation with 6% NaOCl (S2), after irrigation with 2% chlorhexidine (S3), after intracanal dressing (S4), and after 17% EDTA irrigation (S5). Cultivable bacteria recovered from the 5 stages were counted and identified by means of polymerase chain reaction assay (16S rRNA). Both groups had colony-forming unit counts significantly reduced after S2 (P < .05); however, no significant difference was found between the irrigants (S2 and S3, P = .99). No difference in bacteria counts was found between the intracanal medicaments used (P = .95). The most prevalent bacteria detected were Actinomyces naeslundii (66.67%), followed by Porphyromonas endodontalis, Parvimonas micra, and Fusobacterium nucleatum, which were detected in 33.34% of the root canals. An average of 2.13 species per canal was found, and no statistical correlation was observed between bacterial species and clinical/radiographic features. The microbial profile of infected immature teeth is similar to that of primarily infected permanent teeth. The greatest bacterial reduction was promoted by the irrigation solutions. The revascularization protocols that used the tested intracanal medicaments were efficient in reducing viable bacteria in necrotic immature teeth.

What Is The Best Indication For Single-incision Ophira Mini Sling? Insights From A 2-year Follow-up International Multicentric Study.

The Ophira Mini Sling System involves anchoring a midurethral, low-tension tape to the obturator internus muscles bilaterally at the level of the tendinous arc. Success rates in different subsets of patients are still to be defined. This work aims to identify which factors influence the 2-year outcomes of this treatment. Analysis was based on data from a multicenter study. Endpoints for analysis included objective measurements: 1-h pad-weight (PWT), and cough stress test (CST), and questionnaires: International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and Urinary Distress Inventory (UDI)-6. A logistic regression analysis evaluated possible risk factors for failure. In all, 124 female patients with stress urinary incontinence (SUI) underwent treatment with the Ophira procedure. All patients completed 1 year of follow-up, and 95 complied with the 2-year evaluation. Longitudinal analysis showed no significant differences between results at 1 and 2 years. The 2-year overall objective results were 81 (85.3%) patients dry, six (6.3%) improved, and eight (8.4%) incontinent. A multivariate analysis revealed that previous anti-incontinence surgery was the only factor that significantly influenced surgical outcomes. Two years after treatment, women with previous failed surgeries had an odds ratio (OR) for treatment failure (based on PWT) of 4.0 [95% confidence interval (CI) 1.02-15.57). The Ophira procedure is an effective option for SUI treatment, with durable good results. Previous surgeries were identified as the only significant risk factor, though previously operated patients showed an acceptable success rate.

Quantitative Proteomic Analysis Reveals Metabolic Alterations, Calcium Dysregulation, And Increased Expression Of Extracellular Matrix Proteins In Laminin α2 Chain-deficient Muscle.

Congenital muscular dystrophy with laminin α2 chain deficiency (MDC1A) is one of the most severe forms of muscular disease and is characterized by severe muscle weakness and delayed motor milestones. The genetic basis of MDC1A is well known, yet the secondary mechanisms ultimately leading to muscle degeneration and subsequent connective tissue infiltration are not fully understood. In order to obtain new insights into the molecular mechanisms underlying MDC1A, we performed a comparative proteomic analysis of affected muscles (diaphragm and gastrocnemius) from laminin α2 chain-deficient dy(3K)/dy(3K) mice, using multidimensional protein identification technology combined with tandem mass tags. Out of the approximately 700 identified proteins, 113 and 101 proteins, respectively, were differentially expressed in the diseased gastrocnemius and diaphragm muscles compared with normal muscles. A large portion of these proteins are involved in different metabolic processes, bind calcium, or are expressed in the extracellular matrix. Our findings suggest that metabolic alterations and calcium dysregulation could be novel mechanisms that underlie MDC1A and might be targets that should be explored for therapy. Also, detailed knowledge of the composition of fibrotic tissue, rich in extracellular matrix proteins, in laminin α2 chain-deficient muscle might help in the design of future anti-fibrotic treatments. All MS data have been deposited in the ProteomeXchange with identifier PXD000978 (http://proteomecentral.proteomexchange.org/dataset/PXD000978).

Icatibant, An Inhibitor Of Bradykinin Receptor 2, For Hereditary Angioedema Attacks: Prospective Experimental Single-cohort Study.

Hereditary angioedema (HAE) with C1 inhibitor deficiency manifests as recurrent episodes of edema involving the skin, upper respiratory tract and gastrointestinal tract. It can be lethal due to asphyxia. The aim here was to evaluate the response to therapy for these attacks using icatibant, an inhibitor of the bradykinin receptor, which was recently introduced into Brazil. Prospective experimental single-cohort study on the efficacy and safety of icatibant for HAE patients. Patients with a confirmed HAE diagnosis were enrolled according to symptoms and regardless of the time since onset of the attack. Icatibant was administered in accordance with the protocol that has been approved in Brazil. Symptom severity was assessed continuously and adverse events were monitored. 24 attacks in 20 HAE patients were treated (female/male 19:1; 19-55 years; median 29 years of age). The symptoms were: subcutaneous edema (22/24); abdominal pain (15/24) and upper airway obstruction (10/24). The time taken until onset of relief was: 5-10 minutes (5/24; 20.8%); 10-20 (5/24; 20.8%); 20-30 (8/24; 33.4%); 30-60 (5/24; 20.8%); and 2 hours (1/24; 4.3%). The time taken for complete resolution of symptoms ranged from 4.3 to 33.4 hours. Adverse effects were only reported at injection sites. Mild to moderate erythema and/or feelings of burning were reported by 15/24 patients, itching by 3 and no adverse effects in 6. HAE type I patients who received icatibant responded promptly; most achieved improved symptom severity within 30 minutes. Local adverse events occurred in 75% of the patients.

Synthesis And Antiproliferative Activity Of 8-hydroxyquinoline Derivatives Containing A 1,2,3-triazole Moiety.

Twelve novel 8-hydroxyquinoline derivatives were synthesized with good yields by performing copper-catalyzed Huisgen 1,3-dipolar cycloaddition (click reaction) between an 8-O-alkylated-quinoline containing a terminal alkyne and various aromatic or protected sugar azides. These compounds were evaluated in vitro for their antiproliferative activity on various cancer cell types. Protected sugar derivative 16 was the most active compound in the series, exhibiting potent antiproliferative activity and high selectivity toward ovarian cancer cells (OVCAR-03, GI50 < 0.25 μg mL(-1)); this derivative was more active than the reference drug doxorubicin (OVCAR-03, GI50 = 0.43 μg mL(-1)). In structure-activity relationship (SAR) studies, the physico-chemical parameters of the compounds were evaluated and docking calculations were performed for the α-glucosidase active site to predict the possible mechanism of action of this series of compounds.

Communication: Transient Anion States Of Phenol…(h₂o)n (n = 1, 2) Complexes: Search For Microsolvation Signatures.

We report on the shape resonance spectra of phenol-water clusters, as obtained from elastic electron scattering calculations. Our results, along with virtual orbital analysis, indicate that the well-known indirect mechanism for hydrogen elimination in the gas phase is significantly impacted on by microsolvation, due to the competition between vibronic couplings on the solute and solvent molecules. This fact suggests how relevant the solvation effects could be for the electron-driven damage of biomolecules and the biomass delignification [E. M. de Oliveira et al., Phys. Rev. A 86, 020701(R) (2012)]. We also discuss microsolvation signatures in the differential cross sections that could help to identify the solvated complexes and access the composition of gaseous admixtures of these species.
