Antioxidative Propolis From Stingless Bees (Heterotrigona Itama) Preserves Endothelium-Dependent Aortic Relaxation of Diabetic Rats: The Role of Nitric Oxide and Cyclic Guanosine Monophosphate

Propolis from stingless bees (Heterotrigona itama) is a resinous compound that exhibits antihyperglycaemia, free radical scavenging, and cardioprotective properties. The effect of propolis on diabetic vessels has not been investigated. Thus, this research aimed to determine the effect of propolis supplem...

Rol de la fracción espirada de oxido nítrico en el niño con diagnóstico de asma bronquial

El asma es la enfermedad respiratoria crónica pediátrica más frecuente. En la mayoría de los niños se caracteriza por inflamación de la vía aérea de tipo eosinofílica alérgica. La fracción espirada de óxido nítrico (FENO) es un biomarcador de inflamación eosinofílica de vía aérea, su me...

Caracterização do tecido ósseo peri-implantar frente ao uso do óxido nítrico para funcionalização da superfície de implantes instalados na maxila de ratas induzidas à deficiência de estrógeno e síndrome metabólica tratadas com risedronato de sódio

Objetivo: caracterizar o processo de reparo ósseo peri-implantar em maxilas de ratas ovariectomizadas com síndrome metabólica induzida por dieta de cafeteria, tratadas com risedronato e instalação de implantes funcionalizados com [Ru(terpy)(bdq)NO]3+ (TERPY).

Association of serum chemokine ligand 21 levels with asthma control in adults

Clinics; 76 (), 2021
OBJECTIVES: The chemokine ligand (CCL) 21 regulates the maturation, migration, and function of dendritic cells, and has been implicated in the pathogenesis of asthma. This study aimed to investigate the association between serum CCL21 levels and asthma control. METHODS: The serum levels of CCL21 and oth...

Effects of vitamin D-induced supernatant of placental explants from preeclamptic women on oxidative stress and nitric oxide bioavailability in human umbilical vein endothelial cells

Braz. j. med. biol. res; 54 (8), 2021
The study evaluated the effect of the supernatant of placental explants from preeclamptic (PE) and normotensive (NT) pregnant women after tissue treatment with or without vitamin D (VD) on oxidative stress and nitric oxide (NO) bioavailability in human umbilical vein endothelial cells (HUVEC). Placental ...

Cbfa1 expression in vascular smooth muscle cells may be elevated by increased nitric oxide/iNOS

J. bras. nefrol; 42 (3), 2020
ABSTRACT Introduction: Vascular calcification is a common complication of chronic kidney disease. Osteoblast differentiation factor (Cbfa1) is present in histologic sections of arteries from patients with end-stage renal disease. Vascular smooth muscle cells (VSMC) can dedifferentiate to osteoblast-lik...

The effect of nitric oxide, endothelial nitric oxide synthetase, and asymmetric dimethylarginine in hemorrhoidal disease

SUMMARY AIM The aim of this study was to examine the roles of nitric oxide (NOx), endothelial nitric oxide synthetase (eNOS), and asymmetric dimethylarginine (ADMA), which is the major endogenous inhibitor of nitric oxide synthases (NOS), in the pathophysiology of hemorrhoidal disease. METHODS This s...
