Abstract
The impact of hypertension on tissue and organ damage is mediated through its influence on the structure and function of blood vessels. This study aimed to examine the potential of celastrol, a bioactive compound derived from Tripterygium wilfordii Hook F, in mitigating hypertension-induced energy metabolism disorder and enhancing blood perfusion and vasodilation. In order to investigate this phenomenon, we conducted in vivo experiments on renovascular hypertensive rats, employing indirect calorimetry to measure energy metabolism and laser speckle contrast imaging to evaluate hemodynamics. In vitro, we assessed the vasodilatory effects of celastrol on the basilar artery and superior mesenteric artery of rats using the Multi Wires Myograph System. Furthermore, we conducted preliminary investigations to elucidate the underlying mechanism. Moreover, administration of celastrol at doses of 1 and 2 mg/kg yielded a notable enhancement in blood flow ranging from 6 to 31% across different cerebral and mesenteric vessels in hypertensive rats. Furthermore, celastrol demonstrated a concentration-dependent (1 × 10-7 to 1 × 10-5 M) arterial dilation, independent of endothelial function. This vasodilatory effect could potentially be attributed to the inhibition of Ca2+ channels on vascular smooth muscle cells induced by celastrol. These findings imply that celastrol has the potential to ameliorate hemodynamics through vasodilation, thereby alleviating energy metabolism dysfunctions in hypertensive rats. Consequently, celastrol may hold promise as a novel therapeutic agent for the treatment of hypertension.

Changes in the Prescription of Antibiotics and Phytopharmaceuticals in Children Treated for Acute Upper and Lower Respiratory Tract Infections in Pediatric Practices in Germany in 2013, 2018, and 2022. Antibiotics (Basel) 2023; 12:1491. [PMID: 37887192 PMCID: PMC10604680 DOI: 10.3390/antibiotics12101491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 09/17/2023] [Accepted: 09/26/2023] [Indexed: 10/28/2023] Open
Abstract
Background: Little is known about the recent trends in antibiotic and phytopharmaceutical prescribing for acute upper (URIs) and lower respiratory tract infections (LRIs) in children and adolescents. Therefore, this study investigated changes in the prescription of antibiotics and phytopharmaceuticals in children diagnosed with acute URIs and LRIs in pediatric practices in Germany in 2013, 2018, and 2022. Methods: The present retrospective study included children aged 2-12 years diagnosed with acute URIs or LRIs in one of 180 pediatric practices in 2013, 2018, and 2022. The URIs included nasopharyngitis, sinusitis, pharyngitis, tonsillitis, laryngitis and tracheitis, and upper respiratory infections of multiple and unspecified sites, while the LRIs corresponded to bronchitis. The primary outcomes were the proportion of children being prescribed antibiotics and the proportion of those being prescribed phytopharmaceuticals. Results: A total of 120,894 children were diagnosed with acute URIs or LRIs in 2013 compared to 116,844 in 2018 and 127,821 in 2022. The prevalence of antibiotic prescription decreased for all diagnoses between 2013 and 2022. This decrease was statistically significant for both 2013-2018 and 2018-2022 for nasopharyngitis, pharyngitis, and bronchitis. Meanwhile, there was a significant increase in the use of phytopharmaceuticals for all diagnoses between 2013 and 2018. The prevalence of phytopharmaceutical prescription decreased slightly between 2018 and 2022, but this decrease was generally not statistically significant. Conclusions: The prescription of antibiotics has decreased and that of phytopharmaceuticals has increased in children diagnosed with acute URIs and LRIs in Germany over the last decade. More data are needed to corroborate these findings in other settings.

[PMID: 37638214 PMCID: PMC10458336 DOI: 10.1016/j.jsps.2023.101737] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Accepted: 08/01/2023] [Indexed: 08/29/2023] Open
Abstract
The objective of this study was to investigate the effects of cinnamon on the pharmacodynamic (PD) & pharmacokinetic (PK) of amlodipine in hypertensive rats. The hypertensive control group of Wistar rats received L-NAME (40 mg/kg, daily, orally) only. The cinnamon group of rats was treated with cinnamon (200 mg/kg, daily, orally) along with L-NAME. Following 14 days treatment period, blood pressures of rats were monitored at designated intervals over 24 h utilizing a tail-cuff system for measuring blood pressure. To assess the oral PK; amlodipine was administered as a single oral dose of 1 mg/kg to rats and blood samples were collected at specified intervals over 24 h and analysed by UPLC-LC MS/MS. Synergistic decreased in rat's blood pressure was observed in presence of cinnamon + amlodipine. Simultaneous administration of cinnamon ameliorates the Cmax and AUC0-t of amlodipine, the Cmax and AUC0-t was 11.04 ± 1.01 ng/ml and 113.76 ± 5.62 ng h/ml for the cinnamon + amlodipine group as compared to 4.12 ± 0.49 ng/ml and 48.59 ± 4.28 ng h/ml for the amlodipine alone group. The study demonstrates that the use of cinnamon considerably decreases the blood pressure levels and enhances the PK parameters of amlodipine in hypertensive rats.

Abstract
Prunus mume Siebold et Zuccarini is mainly consumed as processed fruits in beverages, vinegar, alcohol, or fruit syrup; studies have reported various functional effects. Many pharmacological and functional studies exist on fruit extracts or processed foods using fruits, however, efficacy studies on various parts of P. mume, including the bark, branches, flowers, and leaves, have not been sufficiently conducted. A previous study revealed that a 70% ethanol extract of P. mume branches induced vascular endothelium-dependent vasorelaxant effects in rat thoracic aortic rings. Therefore, we hypothesized that various parts (the fruits, flowers, leaves, and bark) might have vasorelaxant effects. We evaluated the effects of P. mume extracts on the vascular relaxation of isolated rat thoracic aorta and hypotensive effects in spontaneous hypertensive rats (SHR). A 70% ethanol extract of P. mume bark (PBaE) was the most effective, thus, we investigated its vasorelaxant mechanisms and hypotensive effects. PBaE lowered the blood pressure in SHR and induced the vascular endothelium-dependent relaxation of isolated rat aortic rings via the NO/sGC/cGMP and the PGI2 pathways in the vascular smooth muscle. Potassium channels, such as KCa, KATP, KV, and Kir, were partially associated with a PBaE-induced vasorelaxation. Therefore, PBaE might help prevent and treat hypertension.

Abstract
AIMS The work aimed to study the antihypertensive ability of Haloxylon scoparium. BACKGROUND Haloxylon scoparium Pomel is used to treat various diseases, including hypertension. OBJECTIVE This study aimed to evaluate the antihypertensive effect of Haloxylon scoparium (H. scoparium) in hypertensive rats, and to evaluate its probable vasorelaxant activity. MATERIALS AND METHODS The aqueous extract of Haloxylon scoparium (AEHS) was prepared and used to investigate its antihypertensive ability in L-NAME(Nω-L-arginine methyl ester)-induced hypertensive rats, and its vasorelaxant activity was studied on the isolated thoracic aorta of rats. The acute and subchronic effects of (AEHS) on blood pressure parameters were evaluated after oral administration of AEHS (60 and 100 mg/kg body weight) for 6 h for the acute experiment and for 7 days for the subchronic test. RESULTS The results indicated that AEHS decreased blood pressure parameters (systolic, mean, and diastolic blood pressure) after repeated oral administration in hypertensive rats without affecting normal rats. In addition, AEHS (375-1250 μg/mL) revealed a vasorelaxant effect in thoracic aortic rings precontracted with norepinephrine (NE) (10 μM) or KCl (80 mM). This effect was partially decreased in the presence of nifedipine by inhibition of the vascular calcium channel pathway in isolated rat thoracic aorta. CONCLUSION The study demonstrates the beneficial effect of Haloxylon scoparium as an antihypertensive agent. Moreover, this plant exerts vasorelaxant activity via the blockade of Ca2+ channels.

Abstract
BACKGROUND Complementary and alternative medicine (CAM) has been continuously used worldwide. Various cultures have used this path of healing, and to our date, people are still using it and some even prefer it to modern medicine. Thus, this study aims to analyze awareness, self-use, perceptions, beliefs, and attitudes toward CAM in the general public of Jeddah, Saudi Arabia. METHODS A descriptive observational cross-sectional study was conducted in the public places of Jeddah. Data were collected from 784 participants using a self-administered paper-based questionnaire, and statistical analysis was performed using Statistical Package for the Social Sciences (SPSS). RESULTS The majority of the population was aware of massage (91.8%), herbs (90.7%), nutritional supplements (89.8%), and prayers (88.1%). With regards to usage and effectiveness, prayers and spirituality is used by 75.5% of the population and considered to be the most effective by 76.0%. Respondents obtained information about CAM mostly from friends and relatives (76.6%), followed by media (67.2%), while lack of knowledge about CAM and lack of trained professionals are the most perceived barriers to CAM implementation. Data showed a significant association (p < 0.05) between gender, awareness, and self-use of CAM modalities. Yoga (44.2%) and herbs (72.6%) were mostly used by females, whereas males were mostly aware of cupping (90.4%) and cauterization (76.2%). Another significant association was found between the level of education, awareness, and self-use of CAM modalities indicating that those who were not educated were aware of and used cauterization the most, while those who went to college were more aware of yoga (75.4%). Lastly, having a relative in the healthcare field showed a significant association with awareness of yoga, prayers, and spirituality compared to other CAM modalities. CONCLUSION In conclusion, the present study revealed that the majority of the Western Saudi Arabian population was aware of several CAM modalities and practiced some form of CAM. However, awareness of specific types of CAM may relate to gender, educational level, and relationship to the medical field.

Abstract
To clarify the differences in the clinical application scope of Chrysanthemum morifolium flower (CMF) and Chrysanthemum indicum flower (CIF), two herbs of similar origin, an integrated strategy of network pharmacology, molecular pharmacology, and metabolomics was employed, with a view to investigating the commonalities and dissimilarities in chemical components, efficacy and mechanisms of action. Initial HPLC-Q-TOF-MS analysis revealed that CMF and CIF had different flavonoid constituents. The biological processes underlying the therapeutic effects of CMF and CIF on liver-fire hyperactivity syndrome of hypertension (LFHSH) were predicted to be related to inflammatory response, fatty acid production, and other pathways based on network pharmacology analysis. ELISA, molecular docking, Western blot, and metabolomics techniques showed similar effects of CMF and CIF in lowering blood pressure, resistance to tissue, organ and functional damage, and dyslipidemia. However, distinct effects were found in the regulation of inflammatory response, PI3K-Akt and NF-κB signaling pathways, lipid anabolism, renin-angiotensin system, and metabolic abnormalities. The comparable efficacies of CMF and CIF, despite having distinct mechanisms of action, may be attributed to the integration and counteraction of their different regulating capabilities on the above anti-LFHSH mechanisms. This study offers a vital platform for assessment of differential and precise applications of herbs of close origin with similar but slightly different medicinal properties, and provides a research strategy for bridging Chinese medicine and modern precision medicine.

Abstract
Plant-derived products and their extracted compounds have been used in folk medicine since early times. Zimbro or common juniper (Juniperus communis) is traditionally used to treat renal suppression, acute and chronic cystitis, bladder catarrh, albuminuria, leucorrhea, and amenorrhea. These uses are mainly attributed to its bioactive composition, which is very rich in phenolics, terpenoids, organic acids, alkaloids, and volatile compounds. In the last few years, several studies have analyzed the huge potential of this evergreen shrub, describing a wide range of activities with relevance in different biomedical discipline areas, namely antimicrobial potential against human pathogens and foodborne microorganisms, notorious antioxidant and anti-inflammatory activities, antidiabetic, antihypercholesterolemic and antihyperlipidemic effects, and neuroprotective action, as well as antiproliferative ability against cancer cells and the ability to activate inductive hepato-, renal- and gastroprotective mechanisms. Owing to these promising activities, extracts and bioactive compounds of juniper could be useful for the development of new pharmacological applications in the treatment of several acute and chronic human diseases.

Abstract
BACKGROUND Medicinal plants or herbs produce a bounty of bioactive phytochemicals. These phytochemicals can influence a variety of physiological events related to cardiovascular health through multiple underlying mechanisms, such as their role as antioxidative, anti-ischemic, anti-proliferative, hypotensive, anti-thrombotic, and anti-hypercholesterolemic agents. PURPOSE The purpose of this review is to summarize and connect evidences supporting the use of phytotherapy in the management of some of the most common cardiovascular impairments, molecular mechanisms underlying cardio-protection mediated by herbs, and clinical studies which are positively linked with the use of herbs in cardiovascular biology. Additionally, we also describe several adverse effects associated with some of the herbal plants and their products to provide a balanced set of studies in favor or against phytotherapy in cardiovascular health that may help global discourses on this matter. METHODS Studies relating to the use of medicinal plants were mined by strategically searching scientific databases including Google Scholar, PubMed and Science Direct. Investigations involving approximately 175 articles including reviews, research articles, meta-analyses, and cross-sectional and observational studies were retrieved and analyzed in line with the stated purpose of this study. RESULTS A positive correlation between the use of medicinal plants and cardiovascular health was observed. While maintaining cardiovascular physiology, medicinal plants and their derivatives seem to govern a variety of cellular mechanisms involved in vasoconstriction and vasorelaxation, which in turn, are important aspects of cardiovascular homeostasis. Furthermore, a variety of studies including clinical trials, cross-sectional studies, and meta-analyses have also supported the anti-hypertensive and thus, cardio-protective effects, of medicinal plants. Apart from this, evidence is also available for the potential drawbacks of several herbs and their products indicating that the unsupervised use of many herbs may lead to severe health issues. CONCLUSIONS The cardio-protective outcomes of medicinal plants and their derivatives are supported by ever-increasing studies, while evidences exist for the potential drawbacks of some of the herbs. A balanced view about the use of medicinal plants and their derivative in cardiovascular biology thus needs to be outlined by researchers and the medical community. The novelty and exhaustiveness of the present manuscript is reflected by the detailed outline of the molecular basis of "herbal cardio-protection", active involvement of several herbs in ameliorating the cardiovascular status, adverse effects of medicinal plants, and the clinical studies considering the use of phytotherapy, all on a single platform.

Abstract
The recent outbreak of SARS CoV-2 has changed the global scenario of human lives/economy. A significant number of the non-survivors showed cardiac-renal-vasculature dysfunction. A 'cytokine storm' namely, interleukin IL6-IL1 receptors i.e. IL6R-IL1R over-functioning was reported. Here, nigellidine, an indazole-alkaloid and key-component of Nigella Sativa L. (NS) commonly known as black-cumin-seed was analyzed for COVID-19 protein-targeting and IL1R-IL6R inhibition through molecular-docking-study and biochemical-study in experimental-rat to evaluate antioxidative-capacity. The NMR/X-ray-crystallographic/Electron-microscopic structures of COVID-19 Main-protease (6LU7)/Spike-glycoprotein(6vsb)/NSP2(QHD43415_2)/Nucleocapsid(QHD43423), Human IL1R(1itb)-IL6R(1pm9) from PDB were retrieved-analyzed for receptor-ligand interaction. Then those structures were docked with nigellidine using Autodock and Patchdock-server. A brief comparison was made with nigellicine-thymoquinone from N. sativa. Where nigellidine showed highest binding-energy of -6.6 (kcal/mol), ligand-efficiency of -0.3 with COVID19 Nsp2 forming bonds with amino acid CYS240 present in binding-pocket. Nigellidine showed strong interaction with main-protease (BE:-6.38/LE:-0.29). Nigellidine showed affinity to IL1R (-6.23). The NS treated rat showed marked decline in ALP-SGPT-SGOT-malondialdehyde(MDA) than the basal-levels. From the Western-blot and activity-analysis it was observed that Nigellidine (sulfuryl-group-drug) showed no impact on Phenol-catalyzing ASTIV and Steroid-catalyzing estrogen-sulfotransferase expressions and activities in liver-tissue and thus has no influence in sulfation-mediated adverse metabolic-processes. Conclusively, nigellidine has hepato-reno-protective/antioxidant-immunomodulatory/anti-inflammatory activities with inhibit-potentials of COVID-19 proteins. Further validation is necessary.
