Oxidative stress is a crucial area of investigation among potential etiologies. We examined the hypothesis that blocking the angiotensin type 1 (AT1) receptor with valsartan (VST) in self-nanoemulsifying delivery systems (SNEDS) and loads in liquisolid tablets (LST-1) or valsartan and hydrochlorothiazide (VST/HCTZ) in SNEDS and loads in liquisolid tablets (LST-2) in comparison with non-SNEDS liquisolid tablets (DCT-3 and DCT-4) would lead to an improvement in hypertension management. The present study aims to explore the molecular mechanisms underlying their effect in N(G)-nitro-L-arginine methyl ester (L-NAME)-induced hypertensive rats. Male Sprague-Dawley rats were given L-NAME (40 mg/kg/day) orally for three weeks to inhibit the endogenous synthesis of nitric oxide (NO). Concurrent treatment with VST or VST/HCTZ liquisolid tablets (20 mg/kg/day for three weeks) resulted in lowering blood pressure (BP), reversing the L-NAME-induced serum NO suppression, enhancing lipid profile, and improving oxidative status. The antioxidant defense of paraoxonase was significantly increased in the LST-1- and LST-2-treated rats compared to the L-NAME-treated rats by 135% and 90%, respectively. Furthermore, SNEDS-loaded VST or SNEDS-loaded VST/HCTZ liquisolid tablets significantly lowered the elevated level of AT1 (P < 0.05), showed a marked Nrf2 expression (P < 0.01) and overexpressed PPARγ (P < 0.05), and suppressed iNOS expression (P < 0.0001).

In recent years, the mechanism of action of drugs in SIT has attracted much attention, including the induction of hypersensitivity responses and modulation of immune tolerance. However, scientific challenges remain regarding their mechanism of action and optimization strategies. Studies on pharmacological SIT have been accumulated in the past, and there is an urgent need for bibliometric analyses to review and prospect these results for future academic development. Strict search criteria were developed to screen and download literature information from the Web of Science Core Collection. Six elements of the included literature were analyzed and visualized using Citespace, VOSviewer software, and the Bibliometrix package. A total of 682 publications related to the drug SIT were included in this study. The growth trend in the number of publications is evident and entering a new phase with great potential for the future, with the highest total number of citations in 1998. The countries and institutions with the most publications were the USA and the University of Genoa. The author who contributed the most to the field was Incorvaia, Cristoforo.

However, cooperation and communication are weak, and it is necessary to build a new cooperation mode to promote the globalization of research results.

This manuscript investigates the multifaceted roles of omentin-1 in these conditions, emphasizing its protective effects on vascular function and its potential as both a biomarker and therapeutic target. Clinical studies indicate that reduced circulating levels of omentin-1 are associated with metabolic syndrome (MetS) and increased cardiovascular risk, while animal studies demonstrate its ability to ameliorate endothelial dysfunction and lower blood pressure. Omentin-1 exerts its beneficial effects through various signaling pathways, including AMP-activated protein kinase (AMPK) and protein kinase B (Akt), thereby promoting vasodilation, enhancing insulin sensitivity, and mitigating inflammation. In the context of HF, particularly heart failure with preserved ejection fraction (HFpEF), omentin-1 levels exhibit a negative correlation with diastolic dysfunction and inflammatory markers, suggesting its role in cardiac protection. Additionally, the manuscript discusses the implications of omentin-1 in managing obesity-related cardiovascular diseases and its potential utility as a prognostic marker for adverse outcomes in HF patients. Collectively, omentin-1 represents a promising avenue for research in cardiovascular health, with the potential to inform novel therapeutic strategies aimed at improving outcomes in patients with HTN and HF.
