Depression and anxiety levels in patients with hypertension and relationship with blood pressure control: A review of study design for psychiatric intervention protocol

Arterial hypertension, anxiety, and depression are common in Western and Eastern medicines, with each offering therapeutic instructions and proposals. Arterial hypertension has been identified as a harmful factor that causing cardiovascular diseases and increasing global mortality. Depression affects over 322 million people worldwide, with an overall incidence of 4.4%. In cases of hypertension, depression is observed in approximately 30% of patients when assessed using questionnaires and in approximately 21% when assessed psychiatrically. Anxiety and depression are risk factors for arterial hypertension. On the contrary, hypertension has been considered to cause anxiety and depressive symptoms. This could be attributed to the direct effects of high blood pressure (BP), side effects of antihypertensive drugs, or psychological reactions to the diagnosis of hypertension. An unhealthy lifestyle increases stress and BP levels. Therefore, controlling stress is a complementary therapy for hypertension. In this context, this study presents a protocol aimed at evaluating stress/depression levels as well as the quality of life in patients with hypertension and examining their correlation with BP control and target organ damage. In addition, we will assess the effect of subsequent psychiatric interventions in hypertensive patients with increased levels of depression/stress on BP control, treatment compliance, and quality of life after a follow-up period of 1 year.

Camel's milk also increases carbohydrate metabolism, curing gastrointestinal disorders due to polyunsaturated fatty acids, vitamins, and anti-inflammatory proteins. Its low fat and cholesterol levels, vitamins, minerals, and insulin content make it a critical source of insulin, potentially helping treat diabetes. This review article mainly emphasized the maximum nutritional benefit of camel milk consumption by children or adults suffering from autism spectrum disorders (ASD) after going through extensive reviews of published articles. This article was conducted based on searches in open-source databases like Google Scholar, Embase, DOAJ, PubMed, etc., using specific keywords such as ‘camel milk,’ ‘camel milk benefit,’ ‘camel milk future,’ etc.Camel's milk has been found beneficial for individuals with autism spectrum disorders in India, but further scientific research is needed to comprehend its nutritional and physiological benefits fully.

Date palm (Phoenix dactylifera) bioactive constituents and their applications as natural multifunctional ingredients in health-promoting foods and nutraceuticals: A comprehensive review.

Foods that support human health and longevity are becoming increasingly relevant as substitutes for or adjuncts to pharmacological drugs, either through direct consumption or incorporation into designer foods fortified with health-promoting ingredients. Date palm (Phoenix dactylifera L.) fruits, seeds, and pollen are a cornerstone of diverse food and medicine traditions. Their reported metabolic activities include anti-inflammatory, antioxidant, antihypertensive, antihyperlipidemic, antidiabetic, antitumor, antianemia, hepatoprotective, antibacterial, and antiviral effects. Beneficial effects on gut health and vascular health, as well as effectiveness in alleviating certain dysfunctions of the reproductive system, have also been noted. The genomic diversity of this versatile tree and the diverse agroecological conditions in which it grows lead to appreciable variations in the occurrence of protective nutrients and other high-value bioactive phytochemicals, including flavonoid and non-flavonoid phenolics, carotenoids, phytosterols, and oxylipins, whose potential remains underutilized in the food sector. As food ingredients, date fruits and their co-products can improve the sensory, nutritional, and nutraceutical qualities of a broad range of dietary items. Their high nutritional density can assist with the design of novel or improved products that meet the demand for healthier foods. This review summarizes the current state of evidence on the potentialities of date palm fruits and co-products in functional food development, focusing on the nutrients and extra-nutritional compounds of interest, their biofunctional activities, and factors that influence their abundance and bioactivity. Proofs of concept across food and beverage categories, new developments, and clinical evidence are discussed, followed by recommendations for addressing research gaps.

Based on LC-MS and network pharmacology, the quality components, and anti-hypertensive mechanisms of three types of tea were studied.

Liquid chromatography-mass spectrometry (LC-MS) was used to identify and analyze the main components of Da Hong Pao, Zunyi black tea, and Yunnan Pu'er tea extracts, explore the effects of brewing times on chemical composition, and analyze the differential components using chemometrics. Subsequently, network pharmacology and molecular docking techniques were employed to explore the potential active ingredients and mechanisms of action in combating hypertension (HTN). This study identified eight key chemical constituents of the three teas, with significant differences in their contents. Yunnan Pu'er tea exhibited superior endurance for multiple infusions compared to the other teas. The research results clearly distinguished the three teas, with key components contributing to quality disparities identified as PCA, GC, gallic acid, and caffeine. The tea exerts anti-HTN effects through multiple pathways. The results of eight chemical components and core targets related to HTN exhibited favorable binding affinities. Our study suggested that Da Hong Pao, Zunyi black tea, and Yunnan Pu'er tea exhibit certain quality differences, and the overall quality of Yunnan Pu'er tea surpasses that of the other teas, though specific differences require further investigation. Moreover, the eight identified components from the three teas are all active components in combating HTN, and network pharmacology comprehensively elucidates the mechanism of tea's anti-hypertensive effect. These findings provide more potential key targets for the treatment of HTN by drinking tea. PRACTICAL APPLICATION: Eight common components were identified in Da Hong Pao, Zunyi black tea, and Yunnan Pu'er water extract, with significant differences in content. Yunnan Pu'er has better overall quality compared to Da Hong Pao and Zunyi black tea. The study provides more potential key targets for the treatment of hypertension by drinking tea.

Investigation of the Interaction Between Angiotensin-Converting Enzyme (ACE) and ACE-Inhibitory Tripeptide from Casein

Angiotensin-converting enzyme (ACE) inhibitory peptides exhibit antihypertensive effects by inhibiting ACE activity, and the study of the interaction between ACEs and inhibitory peptides is important for exploring new therapeutic strategies. In this study, the ACE-inhibitory peptide isolated from casein hydrolysate with the amino acid sequence Leu–Leu–Tyr (LLY) exhibited high ACE-inhibitory activity and stability, which holds significant implications for biochemistry and pharmaceutical applications. Furthermore, systematic investigations were conducted on the interaction between ACE and LLY through various approaches. The Lineweaver–Burk plot indicated the non-competitive inhibition pattern of LLY, suggesting that it binds to the enzyme at the non-active site, and the results were further validated by a molecular docking study. Additionally, multispectral experiments and atomic force microscopy were conducted to further elucidate the underlying mechanism of peptide activity. The findings indicated that LLY could induce a conformational change in ACE, thereby inhibiting its activity. This study contributes to a deeper understanding of the mechanism of action of ACE-inhibitory peptides and bears important significance for drug development in hypertension.

Antihypertensive Effect of Perla and Esmeralda Barley (Hordeum vulgare L.) Sprouts in an Induction Model with L-NAME In Vivo

Background: Hypertension is one of the leading causes of premature death worldwide. Despite advances in conventional treatments, there remains a significant need for more effective and natural alternatives to control hypertension. In this context, sprouted barley extracts have emerged as a potential therapeutic option. This study presents the evaluation of the bioactive properties of extracts from two varieties of barley germinated for different periods (3, 5, and 7 days), focusing on their potential to regulate blood pressure mechanisms. Objectives/Methods: The main objective was to assess the effects of these extracts on blood pressure regulation in N(ω)-Nitro-L-Arginine Methyl Ester (L-NAME)-induced hypertensive rats. Renal (creatinine, urea, uric acid, and total protein) and endothelial (NOx levels) function, angiotensin-converting enzyme (ACE) I and II activity, and histopathological effects on heart and kidney tissues were evaluated. Results: In particular, Esmeralda barley extract demonstrated 83% inhibition of ACE activity in vitro. Furthermore, the combined administration of sprouted barley extract (SBE) and captopril significantly reduced blood pressure and ACE I and II activity by 22%, 81%, and 76%, respectively, after 3, 5, and 7 days of germination. The treatment also led to reductions in protein, creatinine, uric acid, and urea levels by 3%, 38%, 42%, and 48%, respectively, along with a 66% increase in plasma NO concentrations. Conclusions: This study highlights the bioactive properties of barley extracts with different germination times, emphasizing their potential health benefits as a more effective alternative to conventional antihypertensive therapies.

Microencapsulation of Hibiscus sabdariffa extract in taro starch: Determination of optimal conditions of bioactive compound retention using response surface methodology

Hibiscus sabdariffa (HS) extract contains a large amount of bioactive compounds with antioxidant, anticarcinogenic, and antihypertensive effects. The extraction of total phenols, flavonoids, and anthocyanins is more efficient at boiling temperature (~91 °C) than that performed at room temperature (~27 °C). In this study, a central composite rotatable design (CCRD) was used to optimize the inlet temperature conditions of a spray dryer and the concentration of taro starch solids to obtain microcapsules with the highest retention of bioactive compounds in hibiscus extracts. Optimized microcapsules (OM) were obtained at an inlet temperature of 118 °C and solid concentration of 26.5 %. Low moisture content (4.54 %) and water activity (0.2) and high content of total phenols (3374.91 mg GAE/100 g), flavonoids (372.81 mg QE/100 g), monomeric anthocyanins (36.74 mg C-3-GE/100 g), and angiotensin-converting enzyme inhibitory activity (80.01 %), were determined in OM using response surface methodology. OM showed a range of spherical agglomerate sizes (10––32 μm). These results indicate that CCRD is a good tool for establishing the optimal conditions for solid concentration and drying temperature to maximize the protection of bioactive compounds using taro starch as the wall material.

Antihypertensive and ACE-2 Inhibitory Effects of Daphne gnidium in Rats.

The antihypertensive activity of Daphne gnidium was tested. Daphne gnidium (Thymelaeaceae) is used against hypertension. The antihypertensive effect of Daphne gnidium was evaluated in this study. The effect of Daphne gnidium aqueous extract (DGAE, 100 and 180 mg/kg) on blood pressure was evaluated in rats. In addition, the vasorelaxant effect of this extract was also tested. DGAE lowered blood pressure in hypertensive rats and exhibited vasorelaxant activity. In addition, cumulative concentrations of DGAE induced vasodilatation through receptoractivated calcium channels (ROCCs) without affecting ACE-2. The aqueous extract of Daphne gnidium exhibits antihypertensive activity and induces vasodilatation via the inhibition of Ca2+ entry.

Exendin-4, a glucagon-like peptide-1 receptor agonist, regulates ductus arteriosus by vasodilation and anti-remodeling through the PKA pathway

The mechanisms of ductus arteriosus (DA) closure involve vasoconstriction and vascular remodeling. Previous findings indicate that the glucagon-like peptide-1 receptor agonist (GLP-1RA) exhibits antihypertensive and anti-remodeling effects in the pulmonary circulation. However, its role in the DA remains unknown. This study aimed to investigate whether exendin-4 (Ex-4), a GLP-1RA, can regulate DA patency and elucidate its mechanisms. After confirming the presence of GLP-1R in neonatal rat DA tissue in vivo, the effects of Ex-4 on DA patency in neonatal rats were sequentially examined. Two hours after birth, we observed spontaneous closure of the DA in control rats. In contrast, Ex-4 prevented the closure of DA, accompanied by reduced intimal thickening. Ex-4 attenuated oxygen-induced vasoconstriction in isolated DA rings ex vivo. This effect was diminished in the presence of H89, a PKA inhibitor. In vitro, Ex-4 inhibited platelet-derived growth factor (PDGF)-BB-induced proliferation and migration of DA smooth muscle cells. Additionally, Ex-4 inhibited PDGF-BB-induced reactive oxygen species (ROS) production, calcium mobilization, and signal transduction of MAPK and Akt pathways. Furthermore, Ex-4 preserved the nuclear expression of Nrf2 attenuated by PDGF-BB. Similarly, all these in vitro effects of Ex-4 were blunted by H89. In conclusion, Ex-4 maintains postnatal DA patency through vasodilatation and anti-remodeling via the PKA pathway. The GLP-1R/PKA pathway emerges as a promising target of DA patency in clinical management.

Pharmacological Attributes of Hesperidin

: Hesperidin is a major flavonoid in sweet oranges and lemons. Aglycone form of hesperidin i.e., hesperetin, and their various derivatives possess significant potential as therapeutic agents for a wide range of diseases and disorders. No signs of toxicity have been observed with the normal intake of hesperidin or related compounds. Hesperidin has been reported to possess a wide range of pharmacological properties, which includes antioxidant, anti-viral, anticancer, antidiabetic, analgesic, organ protective, neuroprotective, antihypertensive, and cardioprotective effects. This needs to be effectively studied at the clinical level so as to firmly establish the usefulness of these compounds in the treatment or prevention of disease in humans. This paper reviews various aspects of hesperidin, including their chemistry, biosynthesis, and bioactivity.

Resistance exercise has an antihypertensive effect comparable to that of aerobic exercise in hypertensive patients: a meta-analysis of randomized controlled trials.

Hypertension increases the risk of cerebrovascular disease and death. In addition to aerobic exercise, which is currently recommended for its antihypertensive effects, recent studies have suggested that dynamic and isometric resistance exercises also have antihypertensive effects. However, the magnitude of the antihypertensive effect of such resistance exercises is not well known. To clarify the differences in these effects, we conducted an umbrella review of a meta-analysis of randomized controlled trials (RCTs). A systematic search was performed on the Ovid MEDLINE and Cochrane Library, covering the period from inception to August 1, 2023. Eligible studies were RCTs comparing the effects of exercise and non-exercise on office, home, or ambulatory blood pressure (BP) in hypertensive patients aged 18 years or older. A random effects model meta-analysis was performed to estimate the effect size across multiple studies. A sub-analysis determined outcomes by the type of exercise (aerobic exercise, dynamic resistance exercise, isometric resistance exercise, and combined exercise). Eighty-four RCTs with 5065 hypertensive patients were included in the study. All exercise significantly reduced systolic BP (SBP) and diastolic BP (DBP) compared to non-exercise (SBP:-7.52 mmHg, 95% confidence interval [CI] -8.77 to -6.27, p < 0.001; DBP: -4.36 mmHg, 95% CI - 5.15 to -3.57, p < 0.001). There were no significant differences in the magnitude of the reduction in BP between the types of exercise (p for interaction = 0.815 for SBP, p = 0.417 for DBP). These data from 84 RCTs showed that exercise intervention significantly reduced BP and that resistance exercise has a similar antihypertensive effect to aerobic exercise in hypertensive patients. This meta-analysis showed that exercise significantly reduced blood pressure in hypertensive patients. There were no significant differences in the magnitude of this reduction in BP between the types of exercise.

Resveratrol Butyrate Esters Reduce Hypertension in a Juvenile Rat Model of Chronic Kidney Disease Exacerbated by Microplastics

Background: Resveratrol is recognized as a promising nutraceutical with antihypertensive and prebiotic properties; however, its bioavailability in vivo is limited. To enhance its bioactivity, we developed resveratrol butyrate esters (RBEs). This study investigates whether RBEs can mitigate hypertension induced by chronic kidney disease (CKD) and exacerbated by microplastics (MPs) exposure in juvenile rats. Methods: Three-week-old male Sprague Dawley rats were fed either regular chow or 0.5% adenine chow for three weeks. The adenine-fed CKD rats (N = 8 per group) received either 5 μM MPs (10 mg/L) or MPs combined with RBE (25 mg/L) in their drinking water from weeks 3 to 9. Results: Our results indicate that MP exposure worsened CKD-induced hypertension, while RBE treatment resulted in a reduction in systolic BP by 15 mmHg (155 ± 2 mmHg vs. 140 ± 1 mmHg, p &lt; 0.05). The combined exposure to adenine and MPs was associated with nitric oxide (NO) deficiency, which RBE treatment alleviated. Additionally, our findings revealed that RBE modulated both the classical and nonclassical renin–angiotensin system (RAS), contributing to its protective effects. We also observed changes in gut microbiota composition, increased butyric acid levels, and elevated renal GPR41 expression associated with RBE treatment. Conclusions: In conclusion, in this juvenile rat model of combined CKD and MP exposure, RBE demonstrates antihypertensive effects by modulating NO levels, the RAS, gut microbiota, and their metabolites.

Effectiveness and Monitoring of Side Effects of Hypertension Drugs in the Elderly in Kalijaga Village

Hypertension is the disease with the highest prevalence in Indonesia. Prevalence of hypertension in the elderly aged 55-75 years and above, which is 62.63% of the overall percentage of people with hypertension. However, many elderly people are not aware and responsive to the treatment of hypertension. The use of anti-hypertensive drugs is often not taken with good procedures. The purpose of this study was to determine the effectiveness and side effects of anti-hypertensive drugs consumed by the elderly in Kalijaga. Sampling using purposive sampling technique with a sample of 30 respondents with blood pressure criteria ≥140/90 mm Hg. Data analysis used wilcoxon and chi-square tests. The results showed a significant effectiveness after the administration of anti-hypertensive drugs as shown by 26 people reaching the target blood pressure therapy. Many of the side effects felt were derived from the use of anti-hypertensive drugs.

Decoding the anti-hypertensive mechanism of α-mangostin based on network pharmacology, molecular docking and experimental validation.

Hypertension is a leading risk factor for disability and deaths worldwide. Evidence indicates that alpha-mangostin(α-MG) can reduce blood pressure and improve target organ damage. Nonetheless, its pharmacological targets and potential mechanisms of action remain inadequately elucidated. We used SwissTargetPrediction to identify α-MG's drug targets and DisGeNET, GeneCards, CTD, and GEO databases for hypertension-related targets, and then determined antihypertensive therapeutic targets of α-MG by intersecting these targets. GO functional enrichment analysis, KEGG pathway analysis, and disease association analysis were conducted using the DAVID database and R package "clusterprofile", visualized with Cytoscape software. The binding affinity of α-MG to identified targets was confirmed through molecular docking using Autodock Vina v.1.2.2 software. The impact of α-MG on target genes was validated using an Angiotensin II-induced hypertensive mouse model and RT-qPCR. A total of 51 potential antihypertensive therapeutic targets for α-MG were identified by intersecting 109 drug targets with 821 disease targets. Furthermore, 10 cellular component terms, 10 disease terms, and the top 20 enriched biological processes, molecular functions, and KEGG pathways related to α-MG's antihypertensive effects were documented. Molecular docking studies indicated a strong binding affinity of α-MG with the HSP90AA1 domain. In Ang II-induced hypertensive mice aorta, treatment with α-MG effectively reversed the aberrant mRNA expression of TNF, HSP90AA1, NFKB1, PPARG, SIRT1, PTGS2, and RELA. Our analyses showed that TNF, HSP90AA1, NFKB1, PPARG, SIRT1, PTGS2, and RELA might be α-MG's potential therapeutic targets for hypertension, laying groundwork for further investigation into its pharmacological mechanisms and clinical uses.

The physiological anti-hypertensive peptide catestatin and its common human variant Gly364Ser: differential cardiovascular effects in a rat model of hypertension.

Catestatin (CST), a 21-amino acids physiological peptide, has emerged as a key modulator of cardiovascular functions due to its anti-hypertensive and cardioprotective properties. However, the ramifications of the most common human variant of CST (viz. Gly364Ser) on cardiovascular pathophysiology remain partially understood. In this study, hypertension was induced in uninephrectomized rats by treatment with deoxycorticosterone-acetate and sodium chloride (DOCA-salt). The DOCA-salt-induced hypertensive (DSHR) animals were then intraperitoneally administered with either CST wild-type (CST-WT) or 364Ser variant (CST-Ser) peptide. CST-Ser was profoundly less effective than CST-WT in rescuing the elevated systolic blood pressure [from ~211 mmHg to ~176 mmHg, p<0.0001 (CST-Ser) versus ~116 mmHg, p<0.0001 (CST-WT)] and heart rate [from ~356 bpm to ~314 bpm, p=0.66 (CST-Ser) versus ~276 bpm, p=0.02 (CST-WT)]. CST-Ser also showed diminished effects in lowering diastolic blood pressure and mean arterial pressure in the DSHR animals. Furthermore, CST-Ser was inefficient/markedly less potent in rescuing the impaired contractile and diastolic function in DSHR animals [improvements in the contractility index by ~22 s-1 (CST-Ser), p=0.15 versus by ~84 s-1 (CST-WT), p<0.0001 and decrease in end-diastolic pressure by ~4 mmHg (CST-Ser), p=0.015 versus by ~14 mmHg (CST-WT), p<0.0001]. Moreover, CST-Ser exerted less potent anti-inflammatory effects on the DSHR hearts than CST-WT. These findings are in concordance with the elevated systolic/diastolic blood pressure observed in Ser variant carriers from various human populations. This study provides compelling evidence for the diminished anti-hypertensive and cardioprotective effects of the CST-Gly364Ser variant.

Optimization of Ultrasound Extraction of Total Anthocyanin From <i>Berberis kaschgarica</i> Rupr. by Response Surface Methodology and Its Antihypertensive Effect

Systematic review of Mendelian randomization studies on antihypertensive drugs

BackgroundWe systematically reviewed Mendelian randomization (MR) studies and summarized evidence on the potential effects of different antihypertensive drugs on health.MethodsWe searched PubMed and Embase for MR studies evaluating the effects of antihypertensive drug classes on health outcomes until 22 May 2024. We extracted data on study characteristics and findings, assessed study quality, and compared the evidence with that from randomized controlled trials (RCTs).ResultsWe identified 2643 studies in the search, of which 37 studies were included. These studies explored a wide range of health outcomes including cardiovascular diseases and their risk factors, psychiatric and neurodegenerative diseases, cancer, immune function and infection, and other outcomes. There is strong evidence supporting the protective effects of genetically proxied antihypertensive drugs on cardiovascular diseases. We found strong protective effects of angiotensin-converting enzyme (ACE) inhibitors on diabetes whereas beta-blockers showed adverse effects. ACE inhibitors might increase the risk of psoriasis, schizophrenia, and Alzheimer’s disease but did not affect COVID-19. There is strong evidence that ACE inhibitors and calcium channel blockers (CCBs) are beneficial for kidney and immune function, and CCBs showed a safe profile for disorders of pregnancy. Most studies have high quality. RCT evidence supports the beneficial effects of ACE inhibitors and CCBs on stroke, diabetes, and kidney function. However, there is a lack of reliable RCTs to confirm the associations with other diseases.ConclusionsEvidence of the benefits and off-target effects of antihypertensive drugs contribute to clinical decision-making, pharmacovigilance, and the identification of drug repurposing opportunities.

Comparison of Forsythia suspensa leaf fermented tea in the four different regions of Shanxi Province: quality, functional ingredients, and bioactivity

BackgroundForsythia suspensa (F. suspensa) is a plant of the Oleaceae family that is used as a medicinal plant. It is a traditional Chinese medicine that functions in clearing heat and detoxification. F. suspensa contains various phytochemicals, such as lignans, flavonoids, triterpenoids, and phenylethanolic glycosides; however, the main active phytochemical in F. suspensa is phillygenin, which has lipid-lowering, antioxidant, antihypertensive, and tyrosinase inhibitory effects. However, the content of phillygenin in F. suspensa is very low, limiting its application.MethodsThis study used wild F. suspensa leaves (FSL) from Lingchuan County (LC), Anze County (AC), Pingshun County (PS), and Pingding County (PD) in Shanxi Province as experimental materials. Through a single factor and orthogonal experimental design, the fermentation time, temperature, and humidity of F. suspensa leaf fermented tea (FSLFT) were optimized using a black tea fermentation machine. By comparing the differences in phillygrin and phillygenin content in FSL and FSLFT, the optimal production process for increasing phillygenin content in FSLFT was sought. This study also compared the differences in bioactive substance content and in vitro antioxidant and antibacterial functions of wild FSLFT from the four counties to evaluate the quality of wild FSLFT from the four counties.ResultsThe optimal technological parameters of Forsythia suspensa leaf fermented tea (FSLFT): fermentation time of 2 h, fermentation humidity of 80%, fermentation temperature of 35°C, the experimental results showed that the order of influence of each factor on phillygenin content was C (fermentation temperature) &amp;gt; A (fermentation time) &amp;gt; B (fermentation humidity). The cellulase activity of FSLFT was significantly higher than that of FSL (P &amp;lt; 0.05). The total volatile compounds of the wild FSLFT from the four counties were 87 volatile aroma components, 13 of which were common aroma components, and the PCA scores ranged from high to low as follows: AZ-FSLFT &amp;gt; LC-FSLFT &amp;gt; PS-FSLFT &amp;gt; PD-FSLFT. The antioxidant effects of the FSLFT were as follows: AZ-FSLFT &amp;gt; LC-FSLFT &amp;gt; PS-FSLFT &amp;gt; PD-FSLFT. PD-FSLFT had the least inhibitory effect on both Gram-positive and Gram-negative bacteria, whereas AZ-FSLFT had the greatest inhibitory effect.ConclusionFermentation promoted the conversion of phillygrin to phillygenin in FSL, which might be related to the increased cellulase activity in FSL during fermentation. The AZ-FSLFT had the best quality and functional activity, which made sense given its active ingredient content. The AZ-FSLFT had the best quality and functional activity, which made sense given its active ingredient content. This study contributes to the comprehensive development and utilization of F. suspensa leaves for economic and healthcare purposes.

Relative protective activities of avenanthramide A, B, and C against H2O2-induced endothelial dysfunction in EA.hy926 cells.

This study compared the antihypertensive effects of avenanthramides A, B, and C, with a focus on their antioxidant and anti-inflammatory properties. Treatment with avenanthramides A, B, and C (50μM) significantly enhanced cell viability and nitric oxide production in H2O2-induced endothelial dysfunction in EA.hy926 cells. Avenanthramides notably increased the levels of antioxidant enzymes and glutathione while reducing malondialdehyde and reactive oxygen species. Moreover, avenanthramides promoted the Nrf2 translocation to nucleus, enhancing the expression of antioxidant enzymes. Furthermore, avenanthramides inhibited the protein levels of iNOS and COX-2, as well as the phosphorylation of IkBα and translocation of p65, thereby mitigating endothelial inflammation. Molecular docking analysis revealed that avenanthramide A exhibited the strongest binding affinity for HO-1 and iNOS, which was correlated with its superior biological activity. Overall, by upregulating Nrf2/HO-1 pathways and downregulating NF-kB pathways, avenanthramides show potential as therapeutic agents for the treatment of endothelial dysfunction.

Antihypertensive effects and changes in extracellular water content by mineralocorticoid receptor antagonists in patients with primary aldosteronism.

In primary aldosteronism (PA), non-suppressible excessive aldosterone secretion due to dietary salt intake significantly contributes to hypertension and cardiovascular complications. Blocking the overactivation of mineralocorticoid receptors (MRs) with mineralocorticoid receptor antagonists (MRAs) is a cornerstone for the medical treatment of PA. However, the role of MRAs in controlling hypertension remains unclear. This study aimed to explore the relationship between changes in body composition parameters (determined by bioelectrical impedance analysis), blood pressure (BP) levels, serum potassium (K+) levels and Study 36-Item Short-Form Health Survey (SF-36) scores after MRA treatment in 50 patients with PA. Treatment with MRAs significantly decreased the systolic BP (SBP) and diastolic BP (DBP) levels and extracellular water (ECW) volume, while it increased the serum K+ levels, active renin concentrations (ARCs), and scores on several SF-36-based quality of life (QOL) subscales. ECW change (ΔECW) and serum K+ change were not significantly associated with changes in SBP and DBP levels. ΔECW showed a significant inverse correlation with ΔARC, suggesting that ARC increases with decreasing ECW volume due to renal MR activity blockade and that ARC is a highly sensitive indicator of ECW volume. In the stratified analysis of patients with PA, ECW volume was significantly decreased in those aged ≥60 years and those with a body mass index of ≥25 kg/m2. In conclusion, MRA treatment showed antihypertensive, biochemical, and QOL improvement effects in patients with PA. The antihypertensive effect may not be related to the decrease in ECW volume due to renal MR activity blockade. Evaluation of ECW using BIA in patients with PA treated with MRAs. Abbreviations: ARC, active renin concentration; BIA, bioelectrical impedance analysis; BMI, body mass index; BP, blood pressure; ECW, extracellular water; K+, serum potassium; MRA, mineralocorticoid receptor antagonist; PA, primary aldosteronism; QOL; quality of life; Δ, parameter changes after MRA treatment.
