OBJECTIVE To study the possible intervention of isoflavones in cytotoxicity induced by cadmium in vascular endothelial cells. METHODS An ECV 304 cell line derived from human umbilical vein endothelial cells was adopted. Genistein/daidzein was added prior to or simultaneously with CdCl2, cell viability was determined by MTT assay, and metallothionein mRNA expression was monitored by RT-PCR met...

The present study is a critical assessment of thermochemical data for gaseous ruthenium oxides based on available experimental data. A full analysis and reinterpretation are presented with proposition new accurate standard formation enthalpies values: Δf H°298(RuO4, g) = −197.6 ± 5.5 kJ mol−1, H°298(RuO3, −53.0 10 H°298(RuO2, 158 20 mol−1 H°298(RuO, 301 28 mol−1.

Four novel anion-nonionic surfactants were synthesized using cashew phenol as raw material. The four structures were characterized by IR and elemental analysis. Their surface activities were investigated. Their critical micelle concentrations (CMC) are 9.30 × 10 mol/L, 8.50 × 10 mol/L, 8.10 × 10 mol/L and 7.71 × 10 mol/L respectively, and the corresponding surface tensions at CMC are 28.38 mN/m...

The present study aimed to investigate the possible influence of several inhibitors and blockers on the vascular effect produced by the acute in vitro application of rosuvastatin to phenylephrine-precontracted aortic rings from rats with a semi-solid, cafeteria-style (CAF) diet. It also aimed to examine the effects of rosuvastatin on the expression of endothelial nitric oxide synthase (eNOS), i...

The aim of this study was to examine the effects of angiotensin II (Ang II) on cellular functions of rat podocytes (pod) in the intact freshly isolated glomerulus and in culture. Membrane voltage (Vm) and ion currents of pod were examined with the patch clamp technique in fast whole cell and whole cell nystatin configuration. Vm of pod was -38+/-1 mV (n = 86). Ang II led to a concentration-depe...

AIMS To determine and quantify the prevalence of patient, provider and system level barriers to achieving diabetes care goals; and to examine whether barriers were different for people with poor glycemic control (HbA1c ≥ 10%; 86 mmol/mol) compared to fair glycemic control (7 to <8%; 53-64 mmol/mol). METHODS We administered a survey by telephone to community-dwelling patients with diabetes, to...

Realizaram-se estudos cinéticos envolvendo a reação de redução de tris(oxalato)cobaltato por L-ácido ascórbico, em diferentes valores de pH. A variação da concentração do complexo de Co(III) foi acompanhada pela absorbância em 600 nm, em condições de pseudo-primeira ordem: [H 2 A] = 3,0 x 10 mol L, [Co(C 2 O 4 ) 3 ] = 3,0 x 10 mol L, na presença de CDTA (3,0 x 10 mol L), em I = 1,0 mol L (NaCl)...

earity was apparent between 0.15 and 10 ␮mol/L (r ϭ 0.99). The recovery was 101% Ϯ 10%. Because serum ubiquinone-10 values in our sample pediatric population did not follow a gaussian distribution (assessed by the Kol-mogorov–Smirnov test), we calculated the median and the 2.5 and 97.5 percentiles for reference values. The ubiquinone concentration was independent of sex (P Ͼ0.05, Mann– Whitney ...

&lt;p&gt;Indonesia salah satu negara berkembang dengan besarnya populasi penduduk dan perkembangan aktifitas yang meningkat setiap tahunnya. Sehingga sampah dihasilkan tidak sebanding pengolahan ada. Pengelolaan baik selain mengganggu pemandangan lingkungan juga dapat berimbas pada kesehatan. Penelitian ini menganalisis efektifitas MOL bonggol pisang sisa nasi pembuatan kompos.&lt;/p&gt;&lt;p&g...
