Effects of Ovine Monocyte-Derived Macrophage Infection by Recently Isolated Toxoplasma gondii Strains Showing Different Phenotypic Traits

open access: yesAnimals, 2022
Ovine toxoplasmosis is one the most relevant reproductive diseases in sheep. The genetic variability among different Toxoplasma gondii isolates is known to be related to different degrees of virulence in mice and humans, but little is known regarding its

Nitric oxide and L-type calcium channel influences the changes in arterial blood pressure and heart rate induced by central angiotesin II

open access: yesBehavioral and Brain Functions, 2008
We study the voltage dependent calcium channels and nitric oxide involvement in angiotensin II-induced pressor effect. The antipressor action of L-Type calcium channel antagonist, nifedipine, has been studied when it was injected into the third ventricle

Study of the Relation between Endothelial Nitric Oxide Synthase G894T Gene Variants and Occurrence of Type II Hepatorenal Syndrome [PDF]

open access: yesAfro-Egyptian Journal of Infectious and Endemic Diseases, 2020
Background  and study aim: The progress of hepatorenal syndrome (HRS) in hepatic patients is not yet understood. Nitric oxide level, through its impact on haemodynamic circulation, may be engaged in the progress of the disease.

Angiotensin II Type 2 Receptor Decreases Transforming Growth Factor-β Type II Receptor Expression and Function in Human Renal Proximal Tubule Cells. [PDF]

open access: yesPLoS ONE, 2016
Transforming growth factor-β (TGF-β), via its receptors, induces epithelial-mesenchymal transition (EMT) and plays an important role in the development of renal tubulointersitial fibrosis.

Lipopolysaccharide induces nitric oxide synthase expression and platelet-activating factor increases nitric oxide production in human fetal membranes in culture [PDF]

open access: yes, 2004
Platelet-activating factor and nitric oxide may be involved in the initiation of human labour as inflammatory mediators. The aim of this study was to test whether platelet-activating factor and lipopolysaccharide were able to induce nitric oxide synthase

Effect of Icariside II and Metformin on Penile Erectile Function, Histological Structure, Mitochondrial Autophagy, Glucose-Lipid Metabolism, Angiotensin II and Sex Hormone in Type 2 Diabetic Rats With Erectile Dysfunction

open access: yesSexual Medicine, 2020
Introduction: Type 2 diabetes mellitus erectile dysfunction (T2DMED) is one of the common complications of type 2 diabetes mellitus (T2DM). Icariside II (ICA II), a flavonoid derived from Epimedium, has been shown to improve erectile function in T2DMED ...

Nitric oxide in acute and chronic inflammation. [PDF]

open access: yes, 2002
PhDNitric oxide (NO) is a signalling molecule formed when L-arginine is converted to L-citrulline by the enzyme NO synthase (NOS. NOS exists as three isoforms, ecNOS is constitutively expressed in endothelial cells and nNOS in neuronal cells, while a ...

Nitric Oxide Differentially Regulates Induction of Type II Nitric Oxide Synthase in Rat Vascular Smooth Muscle Cells Versus Macrophages [PDF]

open access: yesArteriosclerosis, Thrombosis, and Vascular Biology, 2001
Abstract —We studied effects of nitric oxide (NO) released by different NO donors on induction of inducible NO synthase (iNOS) in rat aortic smooth muscle cells (RASMC) and rat macrophage cell line NR8383. iNOS protein expression induced by a CM (interleukin-1β 250 U/mL, interferon-γ 150 U/mL, and tumor necrosis factor-α 150 U ...

Phototriggering Nitric Oxide Synthase from Geobacillus stearothermophilus [PDF]

open access: yes, 2012
Nitric oxide synthases (NOS) produce L-citrulline and nitric oxide (NO) in two turnovers from L-arginine via the bound intermediate, N-hydroxy-L-arginine.
