1. OTIMIZAÇÃO E VALIDAÇÃO DE MÉTODO BASEADO EM QuEChERS PARA DETERMINAÇÃO DE CONSERVANTES EM COSMÉTICOS POR HPLC-DAD
Parabens are widely used as preservatives in the last decades. Others preservatives such as 2-phenoxyethanol, which in addition to his good antimicrobial activity, has low allergenic potential as well others properties of interest to the cosmetic industry. In this work was developed a method for determination of methylparaben (MP), propylparaben (PP) and 2-p

3. Effect of miR-134 against myocardial hypoxia/reoxygenation injury by directly targeting NOS3 and regulating PI3K/Akt pathway
Abstract Purpose To reveal the function of miR-134 in myocardial ischemia. Methods Real-time PCR and western blotting were performed to measure the expression of miR-134, nitric oxide synthase 3 (NOS3) and apoptotic-associated proteins. Lactic dehydrogenase (LDH) assay, cell counting kit-8 (CCK-8), Hoechst 33342/PI double staining and flow cytometry assay

4. O PAPEL DE SUBORDINADO REAL DO CONSELHEIRO POLÔNIO EM QUATRO ADAPTAÇÕES DE HAMLET, DE SHAKESPEARE, PARA OS QUADRINHOS
RESUMO Elaborar um conceito convincente para o personagem Polônio, o conselheiro real da peça Hamlet, de Shakespeare, e sustentá-lo em forma de desenho e com a tipologia dos balões deve ser inicialmente encarado como uma tarefa árdua, na qual se mesclam a propriedade de condensar as múltiplas impressões do estudo da fortuna crítica da peça e a inter

5. In vitro Evaluation of Oxidative Stress Caused by Fine Particles (PM2.5) Exhausted from Heavy-Duty Vehicles Using Diesel/Biodiesel Blends under Real World Conditions
In this work, the redox activity of fine diesel/biodiesel particulate matter (PM2.5) was studied in order to approach its toxicity from reactive oxygen species, due to adverse effects it may cause to human health. The oxidative potential was measured by the dithiothreitol (DTT) assay in order to study the relative contribution of water-soluble transition met

6. Complement system contributes to modulate the infectivity of susceptible TcI strains of Trypanosoma cruzi
BACKGROUND Trypanosoma cruzi is a protozoan parasite and an etiological agent of Chagas disease. There is a wide variability in the clinical outcome of its infection, ranging from asymptomatic individuals to those with chronic fatal mega syndromes. Both parasite and host factors, as well as their interplay, are thought to be involved in the process. OBJECT

7. Impact of chrysosplenetin, per se or in combination with artemisinin, on breast cancer resistance protein (Bcrp)/ABCG2 mRNA expression levels in mice small intestine
ABSTRACT Our previous work revealed that chrysosplenetin in combination with artemisinin inhibited in vivo P-glycoprotein (P-gp, one of classic multi-drug resistance proteins) mediated digoxin transportation activity by reversing the upregulated P-gp/Mdr1 mRNA expression levels by artemisinin. Therefore, chrysosplenetin might be a potential artemisinin-resis

8. DEVELOPMENT OF A SECOND TYPE ELECTRODE BASED ON THE SILVER/SILVER IBUPROFENATE PAIR FOR IBUPROFEN QUANTIFICATION IN PHARMACEUTICAL SAMPLES
Ibuprofen is a widely used pharmaceutical because of its therapeutic properties; it is considered a safe medicament, thus it does not require medical prescription to be sold. However, in order to ensure consumer's health it is indispensable that the pharmaceutical industry relies on analytic methods for its quantification. Potentiometry has proven to be a su

9. Characterization of the third SERK gene in pineapple (Ananas comosus) and analysis of its expression and autophosphorylation activity in vitro
Two somatic embryogenesis receptor-like kinase genes (identified as AcSERK1 and AcSERK2) have previously been characterized from pineapple (Ananas comosus). In this work, we describe the characterization of a third gene (AcSERK3) in this family. AcSERK3 had all the characteristic domains and shared extensive sequence homology with other plant SERKs. AcSERK3

10. Antioxidant and stabilization activity of a quercetin-containing flavonoid extract obtained from Bulgarian Sophora japonica L.
This work aimed to study the antioxidant activity of a quercetin-containing flavonoid extract (FQЕ) obtained from Sophora japonica L. flower buds rich in quercetin (91.6%). Radical scavenging activity was analyzed towards the synthetic radicals DPPH• and ABTS•+ and antioxidant activity was evaluated applying the method of oxygen consumption in a model s

11. Caracterização da diversidade de fungos filamentosos associados a esponjas marinhas e avaliação da produção de lacase = : Diversity of filamentous fungi associated with marine sponges and evaluation of laccase production / Diversity of filamentous fungi associated with marine sponges and evaluation of laccase production
The ocean represents a promissing habitat in the search for new microorganisms, which may have the ability to produce enzymes of industrial interests different from that produced by their terrestrial counterparts. In this context, two samples of the marine sponge Dragmacidon reticulatum were collected on northern coast of São Paulo State, aiming at the char

12. Clonagem e estudos de expressão de enzimas do fungo filamentoso Trichoderma harzianum IOC-3844 envolvidas na degradação de biomassa
The plant biomass is a large-scale available resource and one of its more important applications is the second-generation ethanol production. However, the enzyme cost is one of the biggest barriers for economically viable ethanol from biomass. Therefore, it is important to identify fungal strains that can produce high concentrations of plant biomass-degradin
