1. Graphite-Polyurethane Composite Electrode Modified with Molecularly Imprinted Polymer for Determination of Diclofenac
A molecularly imprinted polymer (MIP) was prepared using the anti-inflammatory diclofenac (DCF) as a template. A non-imprinted polymer (NIP) was also prepared as a control. These MIP and NIP were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Brunauer-Emmett-Teller (BET), revealing a higher porosity in the fir

2. X-ray Scattering and Chemometrics as Tools to Assist in the Identification of Gunshot Residues by Wavelength Dispersive X-ray Fluorescence Spectrometry
Wavelength dispersion X-ray fluorescence spectrometry (WDXRF) is a non-destructive technique and therefore attractive for gunshot residues (GSR) analysis. It is well known for determination of inorganic constituents of samples. However, X-ray scattering region spectral data is not commonly used, although it may provide information about organic constituents

4. Copper Accumulation and Distribution in Two Arboreal Species of the Atlantic Forest
ABSTRACT This study aimed to evaluate the accumulation and distribution of copper (Cu) in the pioneer tree Schinus terebinthifolius R. (aroeira) and non-pioneer tree Eugenia uniflora L. (pitanga) submitted to different concentrations of copper. The plants received 40 mL of Hoagland & Arnon (1950) n. 1 nutrient solution modified with 0.00032, 0.0032, 0.032 an

5. Growth hormone in the tumor microenvironment
ABSTRACT Tumor development is a multistep process whereby local mechanisms enable somatic mutations during preneoplastic stages. Once a tumor develops, it becomes a complex organ composed of multiple cell types. Interactions between malignant and non-transformed cells and tissues create a tumor microenvironment (TME) comprising epithelial cancer cells, cance

6. Grupos econômicos e acumulação urbana na cidade do Rio de Janeiro: Odebrecht e Carvalho Hosken
Resumo As estratégias de acumulação e de poder dos grupos econômicos são centrais para o debate sobre a economia política urbana contemporânea. Sua influência na produção desigual do espaço urbano e na sociedade em geral tem sido cada vez mais proeminente. A partir do referencial analítico das teorias não convencionais sobre grupos econômicos,

7. Polydatin protects H9c2 cells from hypoxia-induced injury via up-regulating long non-coding RNA DGCR5
Polydatin (PD), a monocrystalline polyphenolic drug mainly found in the roots of Polygonum cuspidatum, has various pharmacological activities. Long non-coding RNAs (lncRNA) DiGeorge syndrome critical region gene 5 (DGCR5) was found to participate in the suppression of multiple cancers. Here, we proposed to study the effect of PD on myocardial infarction (MI)

8. Silicate fertilization in non-conventional vegetables in the southern region of Minas Gerais in Brazil
ABSTRACT Considering that the beneficial effects of silicon on human health and it´s accumulation in plants are little explored, studies of mineral nutrition in non-conventional vegetables are extremely relevant. Thus, the objective of this work was to identify non-conventional vegetables responsive to silica fertilization and evaluate the effect of fertili

9. Zn, Co, Cr, As, and genotoxic effects in the ichthyofauna species from polluted and non-polluted/protected estuaries of the São Paulo coast, Brazil
Abstract: The human impact on estuarine regions results in an increasing concentration of trace elements in the environment, exposing aquatic organisms. In this study, Zn, Co, Cr, and As were determined in the muscle tissue of some fish species from Santos-São Vicente (SSV), a recognized polluted region, and in the Cananeia estuary (CAN). Genotoxicity was a

10. How increased atmospheric carbon dioxide and ‘The Law of the Minimum’ are contributing to environmental obesity
Resumo Justus von Liebig observou que era possível aumentar a produção agrícola adicionando pequenas quantidades de nitrogênio (N), fósforo (P) e potássio (K) aos solos. Essa descoberta levou a mais recente revolução agrícola. Contudo, uma vez que a maioria das plantas e microrganismos podem ser não-homeostáticos em relação a composição quím

11. Changes in potato tuber sugar metabolism in response to natural sprout suppressive compounds
ABSTRACT. The increased demand for potato by the Brazilian processing industry requires long term refrigerated storage, but after a few months, natural dormancy ends, and sprouts start to grow. Thus, sprout inhibitors are necessary to reduce the rate of growth and allow further storage. The purpose of research described here was to determine the effects clov

12. EVALUATION OF PROGRESSION OF HEPATIC FIBROSIS IN A GROUP OF PATIENTS WITH NON-ALCOHOLIC FATTY LIVER DISEASE ACCOMPANIED FOR 10 YEARS
RESUMO CONTEXTO: A doença hepática gordurosa não alcoólica vem sendo diagnosticada com frequência progressivamente maior na população geral, como consequência do aumento da prevalência da obesidade e do diabetes mellitus tipo 2, considerados seus principais fatores de risco. Caracteriza-se por acúmulo de gordura nos hepatócitos associada à infl
