2. The compound, diallyl disulfide, enriched in garlic, prevents the progression of doxorubicin-induced nephropathy
Abstract The main medicinal property of garlic is mostly attributed to its organosulfur compounds, of which the oil-soluble diallyl disulfide (DADS) is the principal component of distilled garlic oil. Nuclear factor erythroid 2-related factor 2 (Nrf2) is an important cellular regulator in response to oxidative stress. This study assessed the possible protect

3. Feasibility of Robot - assisted Segmental Ureterectomy and Ureteroureterostomy in Patient with High Medical Comorbidity
ABSTRACT Introduction and objectives Nephroureterectomy remains the gold standard treatment option for upper tract tumors. However, segmental ureterectomy may be another option in patients with single kidney, borderline renal function or high medical comorbidities. The aim of this video is to assess the feasibility of robotic surgery as a minimally invasiv

5. Processos oxidativos avançados: uma revisão de fundamentos e aplicações no tratamento de águas residuais urbanas e efluentes industriais
Resumo A contaminação de águas por espécies tóxicas ou recalcitrantes gera grandes impactos ambientais. Nesse contexto, os Processos Oxidativos Avançados (POAs), tecnologias que utilizam principalmente o radical hidroxila (HO●) para a oxidação dos poluentes, têm se destacado como métodos alternativos promissores no tratamento de águas residuais

6. Three-dimensional reconstructive kidney volume analyses according to the endophytic degree of tumors during open partial or radical nephrectomy
ABSTRACT Objectives To investigate the renal function outcomes and contralateral kidney volume change measured by using a 3-dimensional reconstructive method after open partial nephrectomy (PN) or open radical nephrectomy (RN) according to the endophytic degree of tumors. Materials and Methods We included 214 PN and 220 RN patients. According to the endo

7. Efeitos comparativos do pó da casca do ouriço-do-mar e suplementos de dieta na qualidade da carne e no perfil de ácidos graxos da carne do peito de frangos de corte
Nesse ensaio investigaram-se os efeitos comparativos do pó da casca do ouriço-do-mar e suplementos alimentares sobre a qualidade de carne e o perfil de ácidos graxos de carne de peito de frangos de corte. Cento e oito frangos de corte machos foram distribuídos em 3 grupos (controle, 1% pó da casca do ouriço-do-mar, 1% aditivos alimentares), com 3 repet

8. Estudos mecanísticos da interferência de íons cobre(II) e zinco(II) na reação de Fenton / Mechanistic studies of the interference of the cupper(II) and zinc(II) ions on the Fenton reaction
O objetivo principal deste trabalho foi estudar a interferência de íons Cu2+ e Zn2+ na degradação do fenol pela reação de Fenton (Fe2+/Fe3+ + H2O2). Ambos os íons apresentaram efeito catalítico na reação de Fenton, porém atuam em etapas diferentes durante essa reação. Um dos primeiros intermediários da degradação, o catecol, é capaz de reduz

9. ESTUDO FOTOQUÍMICO DA AÇÃO ANTI-RADICALAR DE COMPOSTOS POLIFENÓLICOS EMPREGANDO ESPECTROFOTOMETRIA E HPLC-UV
The interest in antioxidants has increased considerably in recent years as molecules that reduce lipid peroxidation may minimize or inhibit the oxidative damage caused to DNA, proteins and carbohydrates. Flavonoids, a group of secondary metabolites widely distributed in the plant kingdom, have properties of anti-inflammatory, antibacterial, antiviral, anti-a

10. Oxidative DNA damage induced by S(IV) in the presence of Cu(II) and Cu(I) complexes
O dano ao DNA induzido por S(IV) na presença de alguns complexos de Cu(II) em soluções saturadas com ar foi investigado. A adição de S(IV) a uma solução saturada com ar contendo CuII GGA (GGA = glicilglicil-L-alanina), CuII G3 (G3 = triglicina) ou CuII G4 (G4 = tetraglicina) e traços de Ni(II) origina a formação rápida do respectivo complexo de Cu

12. Antioxidant Activity of Plant Extracts from Brazilian Flora: Study of Electron Paramagnetic Resonance (EPR) and Density Functional Theory (DFT). / Atividade antioxidante de extratos vegetais da flora brasileira: estudo com ressonância paramagnética eletrônica (RPE) e teoria do funcional da densidade (TFD)
There is, in Brazil, a great diversity of vegetable species, and a popular knowledge of several medicinal properties of the some of them. In studies carried out with plants? extracts, there is special interest in antioxidant activities. This work, focused in antioxidant activity, is divided in two parts: the first uses EPR technique to study the antioxidant
