Abstract
Abstract
Background
Nutritional risk is prevalent in various diseases, but its association with contrast-induced acute kidney injury (CI-AKI) remains unclear. This study aimed to explore this association in patients undergoing coronary angiography (CAG).
Methods
In this retrospective cross-sectional study, 4386 patients undergoing CAG were enrolled. Nutritional risks were estimated by nutritional risk screening 2002 (NRS-2002), controlling nutritional status (CONUT), prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI), respectively. CI-AKI was determined by the elevation of serum creatinine (Scr). Multivariable logistic regression analyses and receiver operator characteristic (ROC) analyses were conducted. Subgroup analyses were performed according to age (< 70/≥70 years), gender (male/female), percutaneous coronary intervention (with/without), and estimated glomerular filtration rate (< 60/≥60 ml/min/1.73m2).
Results
Overall, 787 (17.9%) patients were diagnosed with CI-AKI. The median score of NRS-2002, CONUT, PNI, and GNRI was 1.0, 3.0, 45.8, and 98.6, respectively. Nutritional risk was proven to be associated with CI-AKI when four different nutritional tools were employed, including NRS-2002 ([3–7 vs. 0]: odds ratio [95% confidence interval], OR [95%CI] = 4.026 [2.732 to 5.932], P < 0.001), CONUT ([6–12 vs. 0–1]: OR [95%CI] = 2.230 [1.586 to 3.136], P < 0.001), PNI ([< 38 vs. ≥52]: OR [95%CI] = 2.349 [1.529 to 3.610], P < 0.001), and GNRI ([< 90 vs. ≥104]: OR [95%CI] = 1.822 [1.229 to 2.702], P = 0.003). This is consistent when subgroup analyses were performed. Furthermore, nutritional scores were proved to be accurate in predicting CI-AKI (area under ROC curve: NRS-2002, 0.625; CONUT, 0.609; PNI, 0.629; and GNRI, 0.603).
Conclusions
Nutritional risks (high scores of NRS-2002 and CONUT; low scores of PNI and GNRI) were associated with CI-AKI in patients undergoing CAG.

Abstract
Fe-based metal–organic framework (MIL-101(Fe)) was synthesized through a simple solvothermal synthesis and then used to prepare the AuNPs-decorated MIL-101(Fe) nanocomposite (APPPM(Fe)) by a multi-step layer-by-layer assembly process. Benefited from the porous structure of MIL-101(Fe) and the multilayer assemble process, the loading amount of AuNPs on APPPM(Fe) was enhanced and exhibited a fine biocompatible interface and high conductivity. Through the intense Au–S bond, high loading amount of horseradish peroxidase was immobilized on APPPM(Fe) and the native bioactivity of HRP was kept to realize its direct electrochemistry. From the electrochemical kinetics, the constructed biosensor displayed fast electron transfer and good electrocatalysis activity for the detection of nitric oxide (NO) with wide linear range from 0.033 to 5370 μM and a low detection limit of 0.01 μM (3 σ) as well as fine stability, reproducibility and specificity. According to results of real sample analysis, the proposed electrochemical biosensor offers fast and simple detection of NO in real serum. Therefore, the present strategy definitely provided a potential application prospect in NO clinic detection and disease therapy.

Analysis of the Role of Carriership of Polymorphic Genotypes of ESR1, eNOS, and APOE4 Genes in the Development of Arterial Hypertension in Men. Bull Exp Biol Med 2018; 164:753-756.

Abstract
We studied the role of the carrier status for polymorphic loci of genes encoding estrogen receptors (ESR1), endothelial NO synthase (eNOS), and apolipoprotein E (APOE4) and products of their expression nitrogen oxide (NO) and apolipoprotein (ApoE) in the development of arterial hypertension in men. Conventionally healthy volunteers and 149 men with clinical manifestations of stage I-II arterial hypertension were examined. In men with arterial hypertension, the frequency of minor allele A of ESR1 gene was higher (27.5 vs. 9.5% in the reference group; χ2=4.43, p=0.04). The level of NO in the peripheral blood was also higher in the main group (χ2=3.93, p=0.047). The increase in NO concentration did not depend on the presence of polymorphic genotypes (GG and GT) of eNOS gene, but the decrease in ApoE level in blood serum was associated with TC genotype of APOE4 gene (p=0.04). Our results suggest that minor allele A of ESR1 gene is associated with the development of arterial hypertension in men. Reduced content of ApoE in blood serum of men with arterial hypertension was associated with APOE4 gene polymorphism. However, increased level of NO did not depend on polymorphic genotypes GG and GT of eNOS gene. These polymorphisms are of specific interest as additional markers of genetic predisposition to the development of arterial hypertension in middle-age men.

Abstract
A series of clovamide analogues, namely, 1a-13a and 1b-13b, was synthesized and evaluated for their anti-neuroinflammatory activities using BV-2 microglia cells. Among these compounds, six (1b, 4b-8b) showed NO inhibition with no or weak cytotoxicity (CC50 > 100 μM), especially 4b, and showed an IC50 value of 2.67 μM. Enzyme activity and docking assay revealed that the six compounds, especially 4b, target inducible NO synthase (iNOS) and exhibit potent inhibitory effects on iNOS with IC50 values ranging from 1.01 μM to 29.23 μM 4b significantly suppressed the expression of pro-inflammatory cytokines in lipopolysaccharide-stimulated cells. Notably, the oral administration of 4b remarkably improved dyskinesia, reduced the expression of glial fibrillary acidic protein (GFAP)-a marker of neuroinflammation, and increased tyrosine hydroxylase-positive cells in 1-methyl-4-phenyl-1,2,3,6-tetrahydro-pyridine-induced Parkinson's disease (PD) mouse models. These observations demonstrated that 4b is an effective and promising candidate for PD therapy.

Abstract
Aristolochic acid (AA) nephropathy (AAN), a progressive tubulointerstitial injury of toxic origin, is characterized by early and transient acute tubular necrosis. This process has been demonstrated to be associated with reduced nitric oxide (NO) production, which can disrupt the regulation of renal function. In this study, we tested the hypothesis that L-arginine (L-Arg) supplementation could restore renal function and reduce renal injury after AA intoxication. C57BL/6 J male mice were randomly subjected to daily i.p. injection of either sterile saline solution or AA (2.5 mg kg(-1)) for 4 days. To determine whether AA-induced renal injuries were linked to reduced NO production, L-Arg, a substrate for NO synthase, was supplemented (5%) in drinking water. Mice intoxicated with AA exhibited features of rapid-onset acute kidney injury, including polyuria, significantly increased plasma creatinine concentrations, proteinuria and fractional excretion of sodium (P < 0.05), along with severe proximal tubular cell injury and increased NADPH oxidase 2 (Nox2)-derived oxidative stress (P < 0.05). This was associated with a significant reduction in NO bioavailability. L-Arg supplementation in AA-treated mice significantly increased NO bioavailability, which in turn improved renal function (creatininaemia, polyuria, proteinuria, fractional excreted sodium and N-acetyl-β-D-glucosaminidase enzymuria) and renal structure (tubular necrosis and tubular cell apoptosis). These changes were associated with significant reductions in Nox2 expression and in production of reactive oxygen species and with an increase in antioxidant concentrations. Our results demonstrate that preservation of NO bioavailability leads to renal protection in AA-induced acute kidney injury by reducing oxidative stress and maintaining renal function.

Abstract
There is recognition that the obesity epidemic contributes substantially to the increasing incidence of CKD and resistant hypertension (HTN). The mechanisms by which obesity promotes resistance are an area of active interest and intense investigation. It is thought that increases in visceral adiposity lead to a proinflammatory, pro-oxidative milieu that promote resistance to the metabolic actions of insulin. This resistance to insulin at the level of skeletal muscle tissue impairs glucose disposal/utilization through actions on the endothelium that include vascular rarefaction, reductions in vascular relaxation, and vascular remodeling. Insulin resistance derived from increased adipose tissue and obesity has system-wide implications for other tissue beds such as the kidney that affects blood pressure regulation. The additional autocrine and paracrine activities of adipose tissue contribute to inappropriate activation of the renin-angiotensin-aldosterone system and the sympathetic nervous system that promote kidney microvascular remodeling, stiffness, and sodium (Na(+)) retention that in turn promote HTN and in the CKD patient, resistance. In this review, we will summarize the important mechanisms that link obesity to CKD as they relate to resistant HTN.

Oxidative stress: dual pathway induction in cardiorenal syndrome type 1 pathogenesis. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:391790.

Abstract
Cardiorenal Syndrome Type 1 (Type 1) is a specific condition which is characterized by a rapid worsening of cardiac function leading to acute kidney injury (AKI). Even though its pathophysiology is complex and not still completely understood, oxidative stress seems to play a pivotal role. In this study, we examined the putative role of oxidative stress in the pathogenesis of CRS Type 1. Twenty-three patients with acute heart failure (AHF) were included in the study. Subsequently, 11 patients who developed AKI due to AHF were classified as CRS Type 1. Quantitative determinations for IL-6, myeloperoxidase (MPO), nitric oxide (NO), copper/zinc superoxide dismutase (Cu/ZnSOD), and endogenous peroxidase activity (EPA) were performed. CRS Type 1 patients displayed significant augmentation in circulating ROS and RNS, as well as expression of IL-6. Quantitative analysis of all oxidative stress markers showed significantly lower oxidative stress levels in controls and AHF compared to CRS Type 1 patients (P < 0.05). This pilot study demonstrates the significantly heightened presence of dual oxidative stress pathway induction in CRS Type 1 compared to AHF patients. Our findings indicate that oxidative stress is a potential therapeutic target, as it promotes inflammation by ROS/RNS-linked pathogenesis.

Pathogenesis of chronic cardiorenal syndrome: is there a role for oxidative stress? Int J Mol Sci 2013; 14:23011-32.

Abstract
Cardiorenal syndrome is a frequently encountered clinical condition when the dysfunction of either the heart or kidneys amplifies the failure progression of the other organ. Complex biochemical, hormonal and hemodynamic mechanisms underlie the development of cardiorenal syndrome. Both in vitro and experimental studies have identified several dysregulated pathways in heart failure and in chronic kidney disease that lead to increased oxidative stress. A decrease in mitochondrial oxidative metabolism has been reported in cardiomyocytes during heart failure. This is balanced by a compensatory increase in glucose uptake and glycolysis with consequent decrease in myocardial ATP content. In the kidneys, both NADPH oxidase and mitochondrial metabolism are important sources of TGF-β1-induced cellular ROS. NOX-dependent oxidative activation of transcription factors such as NF-kB and c-jun leads to increased expression of renal target genes (phospholipaseA2, MCP-1 and CSF-1, COX-2), thus contributing to renal interstitial fibrosis and inflammation. In the present article, we postulate that, besides contributing to both cardiac and renal dysfunction, increased oxidative stress may also play a crucial role in cardiorenal syndrome development and progression. In particular, an imbalance between the renin-angiotensin-aldosterone system, the sympathetic nervous system, and inflammation may favour cardiorenal syndrome through an excessive oxidative stress production. This article also discusses novel therapeutic strategies for their potential use in the treatment of patients affected by cardiorenal syndrome.

Abstract
BACKGROUND COX-inhibiting nitric oxide donators (CINODs) are a new class of drugs that combine the actions of the parent COX inhibitor with nitric oxide (NO), with the aim of reducing potential toxicity of the parent drug, while maintaining its analgesic and anti-inflammatory effects. AZD3582 (Naproxcinod) is the first in the class of CINODs. OBJECTIVE/METHODS To review the effects of NO donation, CINODS in general and naproxen in osteoarthritis (OA), based on literature in PubMed. RESULTS In preclinical and human studies, this drug produced similar analgesic and anti-inflammatory effects to its parent naproxen, with improved gastrointestinal safety in OA patients. The results of recent clinical trials, which were designed to study effects on blood pressure, are expected shortly, after peer-review. CONCLUSIONS As naproxen is considered the safest COX inhibitor choice from a cardiovascular perspective, AZD3582 has the potential to become a new drug treatment in patients with OA, in whom pain and function are not controlled by the use of analgesics.

Abstract
Endothelial damage and inflammation make a significant contribution to the pathophysiology of sickle cell disease (SCD) and the beta-thalassemia syndromes. Endothelial dysfunction and ensuing vasculopathy are implicated in pulmonary hypertension in the hemoglobinopathies and endothelial activation and endothelial-blood cell adhesion, accompanied by inflammatory processes and oxidative stress, are imperative to the vaso-occlusive process in SCD. Herein, we discuss the role that the endothelium plays in all of these processes and the effect that genetic modifiers and hydroxyurea therapy may have upon endothelial interactions. Therapies targeting the endothelium and endothelial interactions may represent a promising approach for treating these diseases.
