Micromeria biflora mediated gold and silver nanoparticles for colourimetric detection of antibiotics and dyes degradation
The study reports on synthesis of aqueous extract mediated gold and silver nanoparticles of M. biflora (MBAuNPs and MBAgNPs) via hydrated chloroauric acid and silver nitrate salts. The nanoparticles (NPs) were produced in 1:15 (MBAuNPs) and 1:6 (MBAgNPs) ratios under sunlight displaying localized surface plasmon resonance (LSPR) peaks at 541 and 431Â nm, respectively. The sizes characterized by transmission electron, scanning electron, and atomic force microscopic (SEM, TEM, AFM) techniques were respectively 26.73Â nm and 53.81Â nm. The subject NPs demonstrated application in the degradation of methylene blue, Congo red, Rhodamine B, methyl orange, ortho-nitrophenol, and para-nitrophenol ranging from 65 to 86Â %. For detection of levofloxacin, amoxicillin, and azithromycin antibiotics, the MBAuNPs and MBAgNPs exhibited efficiency in real water and biological (blood plasma and urine) samples. Conclusively, the MBAuNPs and MBAgNPs applications for dyes degradation and antibiotics detection was found as simple and cost-effective analytical method
Data of expression status of miR- 29a and its putative target mitochondrial apoptosis regulatory gene DRP1 upon miR-15a and miR-214 inhibition
Data is about the mitochondrial apoptosis regulatory framework genes PUMA, DRP1 (apoptotic), and ARC (anti-apoptotic) analysis after the employment of their controlling miRNAs inhibitors. The data represents putative conserved targeting of seed regions of miR-15a, miR-29a, and miR-214 with respective target genes PUMA, DRP1, and ARC. Data is of cross interference in expression levels of one miRNA family, miR-29a and its putative target DRP1 upon the inhibitory treatment of other miRNAs 15a and 214. Keywords: DRP1, miR-15a, Apoptosis, miRNAs inhibitio
Interplay of N- acetyl cysteine and melatonin in regulating oxidative stress-induced cardiac hypertrophic factors and microRNAs
Early and specific diagnosis of oxidative stress linked diseases as cardiac heart diseases remains a major dilemma for researchers and clinicians. MicroRNAs may serve as a better tool for specific early diagnostics and propose their utilization in future molecular medicines. We aimed to measure the microRNAs expressions in oxidative stress linked cardiac hypertrophic condition induced through stimulants as Endothelin and Isoproterenol. Cardiac hypertrophic animal models were confirmed by BNP, GATA4 expression, histological assays, and increased cell surface area. High oxidative stress (ROS level) and decreased antioxidant activities were assessed in hypertrophied groups. Enhanced expression of miR-152, miR-212/132 while decreased miR-142-3p expression was observed in hypertrophic condition. Similar pattern of these microRNAs was detected in HL-1 cells treated with H2O2. Upon administration of antioxidants, the miRNAs expression pattern altered from that of the cardiac hypertrophied model. Present investigation suggests that oxidative stress generated during the cardiac pathology may directly or indirectly regulate anti-hypertrophy pathway elements through microRNAs including antioxidant enzymes, which need further investigation. The down-regulation of free radical scavengers make it easier for the oxidative stress to play a key role in disease progression.</p
