Ionizing radiation is responsible for oxidative stress by generating reactive oxygen species (ROS), which alters the cellular redox potential. This change activates several sensitive enzymes are crucial in activating signaling pathways at molecular level and can lead to induced inflammation. Therefore, present study was intended assess anti-inflammatory role of ferulic acid (FA), a plant flavonoid, against radiation-induced with novel mechanistic viewpoint. FA administered (50 mg/kg body wt)...
Objective: Several recent studies have implicated a role of endogenous nitric oxide (NO) in the pathophysiology myocardial ischemic/reperfusion injury. However, mechanism by which NO exerts its beneficial/detrimental effects remains unknown. This study examined intracellular signaling studying NO-cGMP pathway on phospho-diesteratic breakdown and turnover phosphoinositides during ischemia reperfusion. Methods: Isolated working rat hearts were made ischemic for 30 min followed A separate group...
The present study evaluated the hepatoprotective effect of aqueous ethanolic Moringa oleifera leaf extract (MoLE) against radiation-induced oxidative stress, which is assessed in terms inflammation and lipid peroxidation. Swiss albino mice were administered MoLE (300 mg/kg body weight) for 15 consecutive days before exposing them to a single dose 5 Gy ⁶⁰Co γ-irradiation. Mice sacrificed at 4 hours after irradiation. Liver was collected immunoblotting biochemical tests detection markers...
The current study was intended to evaluate the hepatoprotective effect of Epicatechin (EC) against radiation-induced oxidative stress, in terms inflammation and lipid peroxidation. Swiss albino mice were administered with EC (15 mg/kg body weight) for three consecutive days before exposing them a single dose 5-Gy (60)Co gamma (γ) irradiation. Mice necropsied livers taken immunohistochemistry, western blot analysis biochemical tests detection markers hepatic stress. Nuclear translocation...
The aggregation kinetics of nC60 and higher-order fullerene (HOF) clusters, i.e., nC70, nC76, nC84, was systematically studied under a wide range mono- (NaCl) divalent (CaCl2) electrolytes using time-resolved dynamic light scattering. Suwanee River Humic Acid (SRHA) also used to determine the effect natural macromolecules on nHOF aggregation. An increase in electrolyte concentration resulted electrical double-layer compression negatively charged nC60s nHOFs alike displayed classical...
To evaluate the protective effect of gossypetin (GTIN) against gamma (γ)-radiation-mediated DNA damage.Increasing concentrations (10-150 μM) GTIN were incubated with supercoiled 1 h prior exposure to γ-radiation in range 5-Gy absorbed dose from Co(60) γ source. establish effective concentration GTIN, was pre-incubated 50 μM for followed by 5, 10 and 20 Gy doses γ-radiation. Moreover, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical, hydroxyl nitric oxide (NO) scavenging, metal chelating...
Biosynthesis of gold nanoparticles (AuNPs) was obtained by a simple chemical reduction method using plant-derived aglycone flavonoid, quercetin, as reducing agent. The aqueous chloroauric acid when exposed to quercetin reduced and converted AuNPs in the size range from 20 45 nm. were characterised UV–visual spectroscopy, transmission electron microscopy, atomic force microscopy dynamic light scattering method. These quercetin-mediated have shown excellent stability for more than 30 days at...
Numerous toxicological studies have focused on injury caused by exposure to single types of nanoparticles, but few investigated how such exposures impact a host's immune response pathogen challenge. Few shown that nanoparticles can alter pathogens (chiefly bacteria) there is even less knowledge the particles viral infections. In this study, we performed experiments investigate if mice single-walled carbon nanotubes (SWCNT) alters mechanisms and titers following subsequent influenza A virus...
Radioprotective action of gossypetin (GTIN) against gamma (γ)-radiation-induced oxidative stress in liver was explored the present article. Our main aim to evaluate protective efficacy GTIN radiation-induced alteration murine system. To effect GTIN, it orally administered mice at a dose 30 mg/kg body weight for three consecutive days prior γ-radiation 5 Gy. were evaluated physiological, cellular, and molecular level using biochemical analysis, comet assay, flow cytometry, histopathology,...
Multiwalled carbon nanotube-titanium dioxide (MWNT-TiO2) nanohybrids (NHs), a promising support for electrocatalysts, have high likelihood of environmental release. Aggregation these NHs may or not be captured by the sum their component behavior, thus necessitating systematic evaluation. This study probes "part-whole question" systematically evaluating role TiO2 loading (C:Ti molar ratios 1:0.1, 1:0.05 and 1:0.033) on aggregation behavior NHs. kinetics in-house synthesized (using sol–gel...
Purpose: The present work was intended to evaluate the radioprotective effect of quercetin against gamma radiation-induced oxidative stress on red blood cells (RBC).Materials and methods: Swiss albino male mice were treated with (100 mg/kg body wt) for three consecutive days prior 5 Gy 60Co-gamma irradiation. RBC isolated estimate level intracellular reactive oxygen species (ROS), membrane lipid peroxidation (LPO), reduced glutathione (GSH), mean corpuscular hemoglobin concentration (MCHC),...

Abstract Aromatic rice (Oryza sativa L.) cultivars are strong aromatic which can thrive well in fields prone to flood, drought and other soil constraints. The present investigation was undertaken determine a suitable media compositions for callus induction regeneration using immature embryo of six grown Bangladesh, namely, Chinigura, Kalijira, Radhuni Pagal, Modhumala, Kataribog Mohonbhog. For different concentrations combinations 2, 4-Dichlorophenoxyaceticacid (2, 4-D) along with NAA were...
In the present study, we investigated arsenic accumulation in different parts of rice irrigated with contaminated water. Besides, also evaluated protective effects Corchorus olitorius leaves against induced toxicities animal model. A pot experiment was conducted amended irrigation water (0.0, 25.0, 50.0 and 75.0 mg/L As) to investigate rice. order evaluate leaves, twenty Wistar albino rats were divided into four groups. The control group (Group-I) supplied normal laboratory pellets while...
Recent evidence suggests that, because of their sorptive nature, if single-walled carbon nanotubes (SWCNTs) make way into aquatic environments, they may reduce the toxicity other waterborne contaminants. However, few studies have examined whether contaminants remain adsorbed following ingestion by organisms. The objective this study was to examine bioavailability and bioactivity ethinyl estradiol (EE2) sorbed onto SWCNTs in a fish gastrointestinal (GI) tract. Sorption experiments indicated...
