1. Antioxidant Effect of Curcumin on the Prevention of Oxidative Damage to the Cochlea in an Ototoxic Rat Model Based on Malondialdehyde Expression
Abstract Introduction Aminoglycoside, as an antimicrobial medication, also has side-effects on the inner ears, bringing about hearing disorders. Curcumin has been proven to be a strong scavenger against various reactive oxygen species (ROS), and the increase in ROS production is considered to play an important role in the process of hearing disorder.

2. Synthesis, Characterization, Spectroelectrochemical, Photophysical and HSA-Binding Properties of Novel and Versatile meso-Tetra(4-pyridylvinylphenyl)porphyrins Coordinated to Ruthenium(II)-Polypyridyl Derivatives
The free-base meso-tetra(4-pyridylvinylphenyl)porphyrin (1a) and its zinc(II) complex were synthesized and then functionalized with [Ru(bpy)2Cl]+ units (2a and 2b) via conventional methods and evaluated in terms of photophysical, electrochemical and biological aspects. All porphyrins present moderate singlet oxygen production and fluorescence quantum yield,

3. Ascorbic acid of cowpea seeds under saline stress
Resumo: A salinidade afeta negativamente o crescimento e o metabolismo vegetal, por desencadear o aumento da produção das espécies reativas de oxigênio (EROs). O ácido ascórbico (AsA) é conhecido por proteger organelas e células contra as EROs evitando seu acúmulo. Assim, objetivou-se estudar os efeitos do AsA em sementes de feijão-caupi submetidas

4. Powdered coconut water (ACP 406®) as an alternative base culture medium for in vitro culture of goat preantral follicles enclosed in ovarian tissue
Abstract This study evaluated a powdered coconut water solution (ACP 406®) as a base culture medium on the in vitro survival and development of in situ goat preantral follicles. The ovarian fragments were either immediately fixed in Carnoy solution (non-cultured control) or individually cultured for 2 or 6 days. The following culture media (all containing 1

5. Does the Glyphosate Treatment Interfere Negatively on RNA Integrity in Glyphosate-Resistant and -Sensitive Conyza bonariensis?
RESUMO: A buva (Conyza bonariensis (L.) Cronq.) está entre as plantas daninhas resistentes ao glifosato mais difíceis de serem manejadas em todo o mundo. Na ciência das plantas daninhas, abordagens moleculares, como o sequenciamento de RNA (RNA-Seq) e a reação da transcriptase reversa da polimerase em tempo real (RT-qPCR), têm sido empregadas para estu

6. Lipid production in Dunaliella bardawil under autotrophic, heterotrophic and mixotrophic conditions
ABSTRACT Many microalgae are rich in lipid. Due to their low growth rates in the autotrophic culture, the best alternative is to cultivate cells under different conditions such as heterotrophic or mixotrophic, which results in the highest yield of biomass and lipid in the shortest duration. In this study, Dunaliela bardawil (UTEX 2538) green microalgae was c

7. Protective effect of Schisandra chinensis total lignans on acute alcoholic-induced liver injury related to inhibiting CYP2E1 activation and activating the Nrf2/ARE signaling pathway
ABSTRACT Schisandra chinensis (Turcz.) Baill., Schisandraceae, is a well-known traditional Chinese medicine used mainly as a recipe for hepatoprotection. Modern researches have revealed that the hepatoprotection is related to its lignans and crude polysaccharide. In this study, we examined the effect and mechanism of S. chinensis total lignans on the liver i

10. Nitrogen source influences the antioxidative system of soybean plants under hypoxia and re-oxygenation
ABSTRACT: In this work, we compared nitrate-supplied plants (non-nodulated) with non-nitrate-supplied plants (nodulated) under oxygen privation of root system (hypoxia) and re-oxygenation (post-hypoxia; recovery) in order to verify whether N sources affect the antioxidant system during oxidative stress caused by hypoxia and post-hypoxia conditions.

11. Impact of phosphate solubilizing bacteria on wheat (Triticum aestivum ) in the presence of pesticides
Resumo Três bactérias solubilizantes de fosfato foram isoladas e identificadas por seqüenciamento de rRNA 16S como Pseudomonas putida, Pseudomonas sp e Pseudomonas fulva. As estirpes foram submetidas a testes bioquímicos de plantas e todos os atributos PGPR foram verificados na presença de pesticidas (clorpirifos e piriproxifeno). O índice de solubili

12. Second-generation pterocarpanquinones: synthesis and antileishmanial activity
Abstract Background: Despite the development of new therapies for leishmaniasis, among the 200 countries or territories reporting to the WHO, 87 were identified as endemic for Tegumentary Leishmaniasis and 75 as endemic for Visceral Leishmaniasis. The identification of antileishmanial drug candidates is essential to fill the drug discovery pipeline for leis
