Evaluation of the Cardiovascular Effects of Coriandrum sativum and Citrus limon to Treat Arsenic-Induced Endothelial Damage and Hypertension in Rats

Based on the vernacular reputation of Coriandrum sativum and Citrus limon to treat hypertension, this study was designed to explore the cardiovascular effects of C. sativum (CS) and C. limon (CL) on arsenic-induced hypertension and endothelial damage. Hypertension was induced by arsenic (100 ppm) in drinking water. The crude methanolic extracts of CS and CL were tested for in vivo and in vitro activities using Power Lab. High performance liquid chromatography analysis of CS and CL showed the presence of phenolic compounds. In anesthetized rats, CS (50 mg) and CL (10 mg) showed a marked decrease in blood pressure of 51% and 35%, respectively. Similarly, ascorbic acid (10 mg) also showed a decreased blood pressure (41%). The CS and CL caused complete relaxation (0.003–5 mg/mL) against phenylephrine (1µM) and high K+ (80 mM)-induced contraction. The CS and CL, independently and in combination, exhibited marked (p < 0.001) attenuation in the blood pressure of the arsenic-induced hypertensive rats when compared with the controls. The beneficial effects of the CS and CL were also observed on lipid peroxidation and eNOS. These data suggest that CS and CL possess significant antihypertensive activity, possibly mediated via endothelium protection, and anti-oxidant effects. Thus, this study provides a rationale for the medicinal use of CS and CL in hypertension and also against arsenic-induced cardiovascular complications

Phytocompounds and Regulation of Flavonoids in In Vitro-Grown Safflower Plant Tissue by Abiotic Elicitor CdCl₂

In this study, a Gas chromatography–mass spectrometry (GC–MS) investigation of embryogenic callus and somatic embryo regenerated shoots of Carthamus tinctorius revealed the presence of a variety of sugars, sugar acids, sugar alcohols, fatty acids, organic acids, and amino acids of broad therapeutic value. The in vitro developed inflorescence contained a wide range of active compounds. In embryogenic calluses, important flavonoids like naringenin, myricetin, kaempferol, epicatechin gallate, rutin, pelargonidin, peonidin, and delphinidin were identified. To augment the synthesis of active compounds, the effect of cadmium chloride (CdCl2) elicitation was tested for various treatments (T1–T4) along with a control (T0). Varying concentrations of CdCl2 [0.05 mM (T1), 0.10 mM (T2), 0.15 mM (T3), and 0.20 mM (T4)] were added to the MS medium, and flavonoid accumulation was quantified through ultra-high-pressure liquid chromatography–tandem mass spectroscopy (UHPLC–MS/MS). The flavonoids naringenin, kaempferol, epicatechin gallate, pelargonidin, cyanidin, and delphinidin increased by 6.7-, 1.9-, 3.3-, 2.1-, 1.9-, and 4.4-fold, respectively, at T3, whereas quercetin, myricetin, rutin, and peonidin showed a linear increase with the increase in CdCl2 levels. The impacts of stress markers, i.e., ascorbate peroxidase (APX), catalase (CAT), and superoxide dismutase (SOD), on defense responses in triggering synthesis were also evaluated. The maximum APX and SOD activity was observed at T3, while CAT activity was at its maximum at T2. The impact of elicitor on biochemical attributes like protein, proline, sugar, and malondialdehyde (MDA) content was investigated. The maximum protein, proline, and sugar accumulation was noted at high elicitor dose T4, while the maximum MDA content was noted at T3. These elevated levels of biochemical parameters indicated stress in culture, and the amendment of CdCl2 in media thus could be a realistic approach for enhancing secondary metabolite synthesis in safflower

Biogenic Synthesis of Zinc Oxide Nanoparticles Using <i>Citrullus colocynthis</i> for Potential Biomedical Applications

Green nanoparticle synthesis is considered the most efficient and safe nanoparticle synthesis method, both economically and environmentally. The current research was focused on synthesizing zinc oxide nanoparticles (ZnONPs) from fruit and leaf extracts of Citrullus colocynthis. Four solvents (n-hexane, methanol, ethyl acetate, and aqueous) were used to prepare the extracts from both plant parts by maceration and extraction. Zinc acetate was used to synthesize the nanoparticles (NPs), and color change indicated the synthesis of ZnONPs. X-ray diffraction, UV spectroscopy, and scanning electron microscopy were used to study the ZnONPs. UV–visible spectroscopy revealed an absorbance peak in the 350–400 nm range. XRD patterns revealed the face-centered cubic structure of the ZnONPs. SEM confirmed a spherical morphology and a size range between 64 and 82 nm. Phytochemical assays confirmed that the complete flavonoid, phenolic, and alkaloid concentrations were higher in unrefined solvent extracts than in nanoparticles. Nanoparticles of C. colocynthis fruit aqueous extracts showed stronger antioxidant activity compared with the crude extracts. Strong antifungal activity was exhibited by the leaves, crude extracts, and nanoparticles of the n-hexane solvent. In a protein kinase inhibition assay, the maximum bald zone was revealed by nanoparticles of ethyl acetate extracts from leaves. The crude extracts and nanoparticles of leaves showed high cytotoxic activities of the n-hexane solvent, with LC50 values of 42.08 and 46.35, respectively. Potential antidiabetic activity was shown by the n-hexane (93.42%) and aqueous (82.54%) nanoparticles of the fruit. The bioactivity of the plant showed that it is a good candidate for therapeutic use. The biosynthesized ZnONPs showed promising antimicrobial, cytotoxic, antidiabetic, and antioxidant properties. Additionally, the in vivo assessment of a nano-directed drug delivery system for future therapeutic use can be conducted based on this study

Exogenous Application of Zinc Sulphate at Heading Stage of Wheat Improves the Yield and Grain Zinc Biofortification

Wheat is the leading staple food in the world, particularly in developing countries, which lacks a mechanism of zinc absorption; when compared to pulses, more attention is consequently important to be given to the wheat crop. Micronutrient deficiencies and especially zinc deficiency influences one-third of the world population. In addition to this, it is also essential for the growth and development of plants and animals. A pot and field experiment was conducted to check the effect of foliar application of zinc sulphate on three different wheat varieties at the same time. Treatment consisted of three zinc levels (control, 4%, 6%) in the form of zinc sulphate (21% Zn) applications were applied on various wheat varieties (Zincol, Fakher-e-Bhakkar, Faisalabad-2008) at different growth stages (tillering, booting and heading). Different zinc levels showed different results on wheat varieties in both experiments. Results revealed that var. Fakher-e-Bhakkar was best at 6% zinc application for more plant height, the number of spikelets, spike length, 100-grain weight, biological and grain yield per plant as compared to other varieties and treatments. Antioxidants and nutritional quality (protein, gluten, starch and zinc contents) showed variable behavior both on wheat varieties and zinc application. It is concluded that Fakher-e-Bhakkar was found to be the most responsive cultivar at 6% zinc application for improvement in growth, yield-related traits and nutritional quality. So it is recommended for achieving maximum yield and yield components and grain zinc contents of wheat under agro-climatic conditions of Layyah, Punjab-Pakistan

Comparative Analysis of Eleven Healthcare-Associated Outbreaks of Middle East Respiratory Syndrome Coronavirus (Mers-Cov) from 2015 to 2017

International audienceSince its emergence in 2012, 2,260 cases and 803 deaths due to Middle East respiratory syndrome coronavirus (MERS-CoV) have been reported to the World Health Organization. Most cases were due to transmission in healthcare settings, sometimes causing large outbreaks. We analyzed epidemiologic and clinical data of laboratory-confirmed MERS-CoV cases from eleven healthcare-associated outbreaks in the Kingdom of Saudi Arabia and the Republic of Korea between 2015-2017. We quantified key epidemiological differences between outbreaks. Twenty-five percent (n = 105/422) of MERS cases who acquired infection in a hospital setting were healthcare personnel. In multivariate analyses, age ≥65 (OR 4.8, 95%CI: 2.6-8.7) and the presence of underlying comorbidities (OR: 2.7, 95% CI: 1.3-5.7) were associated with increased mortality whereas working as healthcare personnel was protective (OR 0.07, 95% CI: 0.01-0.34). At the start of these outbreaks, the reproduction number ranged from 1.0 to 5.7; it dropped below 1 within 2 to 6 weeks. This study provides a comprehensive characterization of MERS HCA-outbreaks. Our results highlight heterogeneities in the epidemiological profile of healthcare-associated outbreaks. The limitations of our study stress the urgent need for standardized data collection for high-threat respiratory pathogens, such as MERS-CoV
