Coriandrum sativum (C. sativum), widely known as coriander, is a herb of global significance, valued for its flavor and therapeutic properties. Originating from the Mediterranean, it has acclimatized to various continents, including Europe, Africa, and Asia.

This review article was compiled from the data obtained from Google Scholar, PubMed/Medline, ScienceDirect, Hinari, and EBSCO.

The herb thrives in areas with favorable agricultural climates, such as India, China, and parts of Europe. The plant's phytochemical spectrum is notably rich, featuring essential oils, flavonoids, phenolic compounds, and fatty acids. The seed oil is predominantly composed of linalool, complemented by γ-terpinene, decanal, and geranyl acetate. Both leaves and seeds are rich in nutrients, including tocopherols, carotenoids, chlorophylls, sugars, ascorbic acid, phenolics, and anthocyanins. C. sativum has shown beneficial effects in easing anxiety, depression, and convulsions, protecting neural health, combating bacteria and fungi, repelling insects, and supporting cardiovascular and diabetic health.

These benefits are mainly due to the combined action of its phytochemicals. The toxicity study of this plant revealed that it is safe when administered in single or multiple doses. The essential oils of the herb have also been explored for their repellent and fumigant capabilities. Various clinical trials have been conducted to evaluate its different pharmacological safety profiles and assess its therapeutic potential.

This review aimed to discuss the botanical features, chemical constituents, pharmacological properties, toxicity studies, and clinical trials. Further study is needed related to embryonic and other toxicities.

The consumption of tea and coffee as beverages is prevalent worldwide, with each having potential health implications. The study investigated the effect of black tea (BT), green tea (GT), and coffee on blood pressure (BP), heart rate (HR), and blood glucose level (BGL) in healthy females.

Forty (40) participants aged 18 to 26 were randomly assigned to four groups: control (250 mL warm water), GT (2 g GT dissolved in 250 mL of hot water), coffee (2 g coffee dissolved in 250 mL of hot water), and BT (2 g BT dissolved in 250 mL of hot water) groups with 10 subjects each. Each group was given its designated drink once a day for three consecutive days. Baseline measurements of BP, HR, and BGL were taken after a 15-minute rest before the consumption of the beverages. Follow-up measurements were taken at 15, 30, 45, and 60 minutes after consumption for cardiovascular indices, and 30 and 60 minutes for BGL. This procedure was repeated for three days.

The results showed no significant changes in BP, HR, and BGL in all the experimental groups compared to the control group.

Coffee and tea are popular beverages enjoyed worldwide, recognized for their numerous health benefits largely due to their bioactive compounds, particularly polyphenols and caffeine. The different concentrations of polyphenols and caffeine in these drinks can affect various physiological functions in distinct ways. The results of the present study showed no significant changes in blood pressure, heart rate, or blood glucose level among healthy young female participants who consumed green tea, coffee, and black tea, respectively. Although some previous studies have indicated that these beverages can significantly impact these health metrics, other research has shown no notable changes. The lack of significant findings in this study may be attributed to its short duration; a more extended study could potentially uncover significant changes.

The findings of this study revealed that green tea, black tea, and coffee have no acute effect on blood pressure, heart rate, and blood glucose levels in healthy female individuals. It can therefore be concluded that green tea, black tea, and coffee have a neutral effect on these physiological parameters, but a more elaborate study is highly recommended.

Chronic renal failure (CRF) triggers chronic systemic inflammation and causes vascular calcification, a prominent contributor to the progression of cardiovascular disease. Adropin and spexin peptides regulate energy balance; also, these peptides trigger anti-inflammatory pathways.

Our present study aimed to clarify the potentially protective impact of spexin and adropin peptides on cardiovascular inflammation in an adenine-induced chronic renal failure model.

The CRF model in Sprague-Dawley rats was established by the administration of adenine hemisulfate for ten days. Then, rats were treated with saline or adropin, or/and spexin for four weeks. CRP, CK, and CK-MB levels in serum were measured by autoanalyzer. Aortic contraction-relaxation responses were determined by the organ bath system. H&E, PAS, and Masson's trichrome stainings evaluated histopathological alterations in both aorta and cardiac tissue. Gene expression levels of ILs (IL1β, IL10, IL17A, IL18, IL21, and IL33), MMPs (MMP1, MMP2, MMP3, MMP9, MMP13, and MMP14), NGAL, TGFβ1, TIMP1, and TNFα in cardiac tissue were evaluated by real-time PCR.

We found increased CK and CK-MB levels by CRF induction. In addition, IL1β, IL17A, IL18, IL21, MMP1, MMP3, MMP13, and MMP14 increased after CRF progression. While adropin has effects on CK levels, spexin decreases CK-MB levels. Also, adropin and spexin had a nitric oxide-dependent impact on vascular reactivity. Besides, spexin downregulated IL1β, IL10, IL17A, TGFβ1, MMP1, MMP3, MMP9, MMP13, MMP14 and NGAL; however, the adropin peptide had a limited effect.

These results suggest that adropin and spexin have potential preventive roles on vascular damage in CRF progression via modulation of MMPs and inflammatory genes.

Pulmonary Hypertension (PH) is a significant contributor to cardiac mortality in Dilated Cardiomyopathy (DCM) patients. Inflammatory processes and oxidative stress play pivotal roles in the advancement of Pulmonary Hypertension (PH). The Monocyte-to-High-Density-Lipoprotein Cholesterol Ratio (MHR), a newly identified biomarker indicative of inflammatory and oxidative stress, has not been extensively researched in the context of pulmonary hypertension, especially within the scope of dilated cardiomyopathy.

Given the reason mentioned above, our research explores the correlation between the MHR and the severity of PH in patients suffering from DCM.

In this study, we conducted a retrospective review of medical data from 107 individuals diagnosed with non-ischemic DCM, evaluating their clinical profiles, biochemical indicators, MHR, and echocardiographic parameters. We analyzed the relationships between Pulmonary Arterial Systolic Pressure (PASP) and the Ejection Fraction of the Left Ventricle (LVEF). Utilizing logistic regression analysis, we determined the predictors of PH.

Findings indicated that the DCM-PH group exhibited a significantly larger male population and elevated New York Heart Association (NYHA) classification scores (both with p-values <0.001 and 0.01, respectively) compared to the DCM-only group. A positive association was observed between the PASP and parameters, such as the Dimensions of the Left Atrium (LAD) and Left Ventricle in Systole (LVDs), Monocyte (M) levels, Direct Bilirubin (DB), and MHR. Conversely, an inverse relationship was noted with serum lipid profiles, including Total Cholesterol (TC), HDL Cholesterol (HDL-c), and apolipoprotein A1. LVEF demonstrated positive linkage with the same lipid profiles and the Left Ventricular Posterior Wall Thickness (LVPWT) yet showed negative correlations with the NYHA classification, Red Blood Cell Distribution Width Standard Deviation (RDW-SD), Total Bilirubin (TB), Direct Bilirubin (DB), and dimensions of the left ventricle in diastole and systole, as well as MHR. Through logistic regression analysis, several factors were recognized as significant predictors for the severity of PH within the DCM cohort, with weight (OR1.20, CI 1.022-1.409, p=0.026), RDW-SD (OR1.988, CI 1.015-3.895, p=0.045), LVPW (OR3.577, CI 1.307-9.792, p=0.013), LVDd (OR1.333, CI 1.058-1.680, p=0.015), MHR (OR3.575, CI 1.502-8.506, p=0.032), and TB (OR1.416, CI 1.014-1.979, p=0.041) showing positive associations, while apoB (OR0.001 CI0.001-0.824, p=0.045) exhibiting negative associations, all with p-values <0.05.

Higher MHR and LVD correlate with increased PASP and reduced LVEF in DCM-PH patients. MHR and LVPW are independent predictors of PH severity, indicating their potential as novel severity markers in DCM-related PH.
