Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the most recent findings investigating the impact of several natural sirtuin (SIRT) activators, particularly SIRT1, on atherosclerosis. RECENT FINDINGS Sirtuins that belong to a family of class III histone deacetylases are believed to be novel therapeutic targets to treat age-related and chronic diseases. SIRT expression is regulated by small molecules called SIRT-activating compounds that can be found in natural food products. SIRT1 may exert protective effects in atherosclerosis, which is said to be a major cause of cardiovascular diseases. Most of the evidence supporting the beneficial effects of these natural compounds comes from in vitro or animal-based studies, while there have been particularly few or inconsistent human-based studies evaluating their long-term impact in recent years. SIRT1 activation has been demonstrated to mitigate or prevent atherosclerosis through various mechanisms. However, further research is required to determine the optimal SIRT activator dosage and to establish a stronger correlation between health effects and the administration of bioactive compounds. Additionally, conducting more human clinical trials is necessary to ensure the safety of these compounds for preventing atherosclerosis development.

Polyphenols and Brazilian red propolis incorporated into a total-etching adhesive system help in maintaining bonding durability. Heliyon 2021; 7:e06237.

Abstract
Objectives The aim of this study was to evaluate the degree of conversion and bond strength of a commercial dental adhesive modified by the incorporation of quercetin, resveratrol (RES), and Brazilian red propolis (BRP). Methods BRP markers were identified using ultra-performance liquid chromatography coupled with a diode array detector, and the antioxidant activity (AAO) of the three substances was analyzed. Single Bond 2 adhesive (3M ESPE) was modified by adding BRP, quercetin, and RES, separately, at 20 μg/mL, 250 μg/mL, and 500 μg/mL, respectively. The degree of conversion (DC) was measured using near-infrared spectroscopy 24 h after photopolymerization. Measurements of the resin-dentin microtensile bond strength (μTBS) were carried out after 1 day and 1 year. Student's t test and ANOVA with Tukey's test were used for data analysis (α = 0.05). Results The markers daidzein, liquiritigenin, pinobanksin, isoliquiritigenin, formononetin, pinocembrin, and biochanin A were found in the ethanolic extract of BRP. Quercetin, RES, and BRP showed high AAO. The DC of the tested adhesives remained adequate for this category of material, with a slight increase in the DC of adhesives with quercetin and BRP (P > 0.05). Comparisons between μTBS measurements made at 1 day and 1 year showed that, contrary to the control group, μTBS values for all modified adhesives were maintained after 1 year in distilled water (P > 0.05). Conclusions These findings suggest that quercetin, RES, or BRP might be useful in adhesive dentistry to help improve hybrid layer resistance. Clinical significance Dentin bonding agents with quercetin, RES, and BRP have potential to increase the longevity of composite restorations.

Arch Med Sci Atheroscler Dis 2021; 6:e158-e165. [PMID: 34703944 PMCID: PMC8525249 DOI: 10.5114/amsad.2021.109255] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Accepted: 07/21/2021] [Indexed: 05/13/2023] Open
Abstract
INTRODUCTION Smooth muscle cells (SMCs) are considered to be the main producer of matrix metalloproteinase-2 (MMP-2) participating primarily in extracellular matrix (ECM) remodeling. Any disturbances in ECM structure may underlie the pathogenesis of many cardiovascular diseases and contribute to angiogenesis, cancer development, invasion or metastasis. The purpose of the study was to examine the effect of oxidative stress on the expression of MMP-2, its tissue inhibitor type 1 (TIMP-1) and cyclooxygenase-2 (COX-2) in human aortic smooth muscle cells (HASMCs). MATERIAL AND METHODS HASMCs were treated with exogenously applied H2O2 or TNF-α. N-acetylcysteine (NAC) was used as an antioxidant. Gene expression levels were measured by real-time PCR and the protein levels were determined using ELISA assay. RESULTS The studies revealed no association between oxidative stress and either mRNA quantity or protein secretion of MMP-2 and TIMP-1. However, we found markedly reduced (p < 0.001) MMP-2 secretion in cells incubated with NAC. HASMCs stimulated with TNF-α demonstrated a significantly increased COX-2 mRNA level as well as enzyme activity. H2O2-induced cells showed lowered COX-2 activity in comparison to untreated cells. MMP-2 and TIMP-1 expression did not change after COX-2 inhibition with DuP-697. CONCLUSIONS We did not find any effect of oxidative stress on expression of MMP-2 and TIMP-1 in HASMCs. However, COX-2 mRNA and protein level were elevated in these conditions. There was no correlation between COX-2 activity and MMP-2 and TIMP-1 mRNA expression or protein secretion.

Abstract
Arterial remodelling refers to the alteration in the structure of blood vessel that contributes to the progression of hypertension and other cardiovascular complications. Arterial remodelling is orchestrated by the crosstalk between the endothelium and vascular smooth muscle cells (VSMC). Vascular inflammation participates in arterial remodelling. Resveratrol is a natural polyphenol that possesses anti-oxidant and anti-inflammatory properties and has beneficial effects in both the endothelium and VSMC. Resveratrol has been studied for the protective effects in arterial remodelling and gut microbiota, respectively. Gut microbiota plays a critical role in the immune system and inflammatory processes. Gut microbiota may also regulate vascular remodelling in cardiovascular complications via affecting endothelium function and VSMC proliferation. Currently, there is new evidence showing that gut microbiota regulate the proliferation of VSMC and the formation of neointimal hyperplasia in response to injury. The change in population of the gut microbiota, as well as their metabolites (e.g., short-chain fatty acids) could critically contribute to VSMC proliferation, cell cycle progression, and migration. Recent studies have provided strong evidence that correlate the effects of resveratrol in arterial remodelling and gut microbiota. This review aims to summarize recent findings on the resveratrol effects on cardiovascular complications focusing on arterial remodelling and discuss the possible interactions of resveratrol and the gut microbiota that modulate arterial remodelling.
