Abstract
Objective: To investigate the ability of docosahexaenoic acid (DHA)-loaded silver nanoparticles (AgNPs) in facilitating the incorporation of DHA in the cell membrane, improve cell membrane structure, and attenuate endothelial dysfunction in experimental diabetes. Methods: DHA/AgNPs were prepared using a nanoprecipitation technique. Fifty male albino rats were used in this study; 10 of them were served as the control group and 40, as the experimental groups, were injected with streptozotocin. Then, the experimental groups were subdivided into diabetic, diabetic treated with DHA, diabetic treated with AgNPs, and diabetic treated with DHA/AgNPs groups. Results: DHA/AgNPs have small spherical size as proved from ultraviolet–visible spectroscopy, transmission electron microscope, dynamic light scattering, and scanning electron microscope techniques. Cell membrane cholesterol and triglycerides showed a significant elevation in the diabetic group compared to the control, but treatment with DHA and DHA/AgNPs caused a significant reduction in both. Treatment with AgNPs and DHA/AgNPs caused a significant improvement in asymmetric dimethylarginine and nitric oxide levels compared to the diabetic group. Cell membrane fatty acids showed that omega-6 polyunsaturated fatty acids (PUFAs) were significantly elevated, while omega-3 PUFA were significantly reduced in the diabetic group compared to the control. There is a significant improvement in the levels of fatty acids in all groups after treatment with DHA, silver, or DHA/AgNPs. Conclusion: DHA/AgNPs are potent agents for the improvement of diabetic complication and endothelial dysfunction in experimental diabetes.

Abstract
High throughput production of silver nanoparticles (AgNPs) having controlled size appropriate for industrial purposes were achieved via using facile and ecofriendly chemical reduction method. Native rice starch was used as reductant for silver ions (Ag+) to silver atoms (Ag0), as well as stabilizing for the obtainable AgNPs. Two different concentrations; 2000 ppm and 4000 ppm were successfully prepared and coded as AgNPs-2000 and AgNPs-4000 respectively. The attained AgNPs were characterized via ultra-visible (UV-vis) spectra, Transmission Electron Microscope (TEM), Energy dispersive X-ray (EDX), Particle size analyzer, polydispersity index (PDI) and zeta potential (ζ-potential). The average particle size of AgNPs (2000 ppm) was 8 nm with PDI = 0.01 which affirm the monodispersity and homogeneity of the produced AgNPs. Meanwhile, the size majority for the as prepared AgNPs (4000 ppm) was 24 nm with PDI = 0.021. Based on the aforementioned data, AgNPs prepared with a high concentration (4000 ppm) compared with the commercialized ZnNPs were used for the genotoxicity study on onion. Root-tips was used for cytogenetic studies using onion (Allium cepa L.) which are excellent materials for cytological and genotoxicity studies. Genotoxicity results explored that, by using AgNPs ≥40 ppm, the abnormalities disturbed chromosomes were observed and detected, that reflects the genotoxicity effect of these nanoparticles at this dose. In addition, the commercial available ZnNPs with the recommended dose (2 g/L) displayed also severe genotoxicity on A. cepa L. root meristem cells.

Abstract
INTRODUCTION The effects of edaravone against pentylenetetrazole (PTZ)-induced epilepsy in male albino rats were investigated. Edaravone is a well-known commercial drug used in the treatment of strokes and amyotrophic lateral sclerosis (ALS). Antioxidant and free radical scavenging activities of edaravone have been reported in patients with ALS. METHODS In this study, the experimental groups were as follows: sham, control, 5 mg/kg edaravone, and 10 mg/kg edaravone. Behavioral assessment, determination of biochemical markers, apoptosis, nitric oxide (NO), and mRNA and protein expression of cyclooxygenase-II (COX-II) were carried out. Seizure incidence, including generalized tonic-clonic seizure (GTCS) and minimal clonic seizure (MCS), was directly associated with PTZ administration in rats. RESULTS Edaravone supplementation substantially increased MCS and GTCS latency in rats, and biochemical markers were significantly altered in the brain tissue of PTZ-treated rats. Edaravone treatment normalized altered biochemical markers compared with the untreated control. Apoptosis and NO levels were significantly reduced by more than 50% compared to their respective controls. COX-II mRNA was increased by 130% in PTZ-treated rats, while edaravone supplementation reduced mRNA and protein expression of COX-II by more than 20% and 40%, respectively. Immunohistochemistry indicated that COX-II protein expression was reduced by 13.2% and 33.7% following supplementation with 5 and 10 mg/kg edaravone, respectively. CONCLUSION Taken together, our results suggest that edaravone functions by downregulating the levels of COX-II and NO and is a potential candidate for the treatment of PTZ-induced epilepsy.

Abstract
The current study evaluated the anti-inflammatory and anxiolytic activities of Euphorbia hirta extract in neonatal asthmatic rats. Rats were assigned to the following groups: group I, sham (normal rats); group II, control (asthmatic rats); group III, E. hirta extract (100 µg/100 µl) and group IV, E. hirta extract (200 µg/100 µl). We performed a phytoscreening analysis of E. hirta extract. Inflammatory cell counts in the bronchoalveolar lavage fluid, levels of anti-inflammatory and antioxidant markers, apoptosis, and a histopathological analysis were carried out. An open field test determined anxiolytic activity, an elevated plus maze, a hole board test, and a cross test. The presence of 9,12,15-octadecatrien-1-ol, pentadecylic acid, ethyl linoleate, 1,2,3-trihydroxy benzene, gamma-tocopherol, 5-hydroxymethyl-2-furancarboxaldehyde, myristic acid, 7,10-octadecadienoic acid methyl ester, phytol, ethyl palmitate, and squalene in E. hirta extract was noted. Following treatment with E. hirta extract, total leukocytes, eosinophils, tumor necrosis factor-α (TNF-α), interleukin (IL-6), and lipid peroxidation were reduced, whereas antioxidant levels were increased. The mRNA expression levels of TNF-α, inducible nitric oxide synthase, IL-6, cyclooxygenase-2, caspase-3, p53, nerve growth factor precursor, and Bax were reduced, whereas that of Bcl-2 was increased. Apoptosis and caspase-3 protein expression were significantly reduced. Treatment of rats with E. hirta extract significantly reduced inflammation and eosinophil infiltration in the lungs. Taken together, these results led us to conclude that E. hirta extract has anti-inflammatory and anxiolytic effects on neonatal asthmatic rats with inflammation.

Abstract
The evaluation of cytotoxic and apoptotic activities of silver nanoparticles (Ag-NPs) synthesized by aqueous extract of Prosopis farcta was investigated against lung (A549) and colon (HT-29) cell lines. The cytotoxic activity of nanoparticles was performed using MTT assay, while their apoptotic activity was tested using TUNEL method. The obtained results of MTT showed that the cell viability of A549 was dependent on the nanoparticles concentration and incubation time. Therefore, although the cytotoxic effect increased as the Ag-NPs concentration and incubation time heightened, yet the viability of HT-29 cells seems to be dependent only on the incubation time. The apoptotic results of the nanoparticles showed more than 50% of apoptosis on A549 and HT-29 cell lines, which in this case, HT-29 demonstrated 100% apoptosis at concentrations of more than 400 µg/ml. It seems that Ag-NPs synthesized using P. farcta extract can serve as anti-cancer agent in the treatment many cancers through creating or discovering new drug forms.

Abstract
The protective effect of taurine against inflammation, apoptosis and oxidative stress in traumatic brain injury was investigated in the present study. Taurine is a non-proteogenic and essential amino acid in animals. It plays a critical nutritional role in brain cell growth, differentiation, and development. Taurine is involved in regeneration and neuroprotection in the injured nervous system, and is an effective antioxidant against lead-, cadmium-, and exercise-induced oxidative stress. Astrocytes and neuron cells were co-cultured and cells were treated with different concentrations of taurine (100, 200 and 300 mg/l) for 72 h, and the levels of reactive oxygen species, malondialdehyde, reduced glutathione, glutathione peroxidase, superoxide dismutase, catalase, acetylcholinesterase, tumor necrosis factor-α, interleukin-6, caspase-3, p53, B-cell lymphoma 2 and Bcl-2-associated X protein were determined. These inflammatory, apoptotic, and oxidative stress markers were substantially increased in injured cells, and returned to normal levels following taurine supplementation. Thus, taurine supplementation may be effective against oxidative stress, apoptosis, and inflammation in injured brain cells.

Abstract
Hyperglycemia-induced overproduction of reactive oxygen species (ROS) is an important contributor to type 2 diabetes (T2D) pathogenesis. The conventional antioxidant therapy, however, proved to be ineffective for its treatment. This may likely be due to limited absorption profiles and low bioavailability of orally administered antioxidants. Therefore, novel antioxidant agents that may be delivered to specific target organs are actively developed now. Metallic nanoparticles (NPs), nanosized materials with a dimension of 1–100 nm, appear very promising for the treatment of T2D due to their tuned physicochemical properties and ability to modulate the level of oxidative stress. An excessive generation of ROS is considered to be the most common negative outcome related to the application of NPs. Several nanomaterials, however, were shown to exhibit enzyme-like antioxidant properties in animal models. Such NPs are commonly referred to as “nanoantioxidants.” Since NPs can provide specifically targeted or localized therapy, their use is a promising therapeutic option in addition to conventional therapy for T2D. NP-based therapies should certainly be used with caution given their potential toxicity and risk of adverse health outcomes. However, despite these challenges, NP-based therapeutic approaches have a great clinical potential and further translational studies are needed to confirm their safety and efficacy.

Abstract
OBJECTIVE To investigate and compare between the effect of both silver nanoparticles (AgNPs) and zinc oxide nanoparticles (ZnONPs) on insulin signaling pathway and insulin sensitivity in experimental diabetes. Preparation of AgNPs and ZnONPs in their solid state were carried out using pullulan (Natural polymer) as both reducing and stabilizing agent. The synthesis of these nanoparticles in a large scale were carried out without using any solvents. The experimental male albino rats received diluted solutions of AgNPs and ZNONPs. After the experimental period, blood was withdrawn; erythrocyte membrane lipids were extracted and fatty acids were determined by HPLC. Oxidant, antioxidant profile and phosphatidylinositol 3-kinase (PI3K) were estimated. RESULTS It was observed that the as synthesized AgNPs and ZnONPs have nearly spherical shape with small size due to the stabilization effect of pullulan as proved by UV-vis spectroscopy (UV-vis), Transmission electron microscy (TEM) and Field emission scanning electron microscopy (FESEM), Zeta potential, Dynamic light scattering (DLS) and X-ray diffraction (XRD) techniques. The average hydrodynamic size of the formed AgNPs was 15 nm which is considered as very small size when compared with that of ZnONPs (above 50 nm). Fasting blood sugar was significantly increased in diabetic group along with elevation of MDA and DNA damage indicating the oxidative properties of streptozotocin. Whereas, the treatment with nanoparticles significantly attenuated these elevations. CONCLUSION AgNPs and ZnONPs represent promising materials in attenuating diabetic complications and insulin resistance in experimental diabetes; no Impressive differences were observed between the effect of ZnONPs and AgNPs in this current research.

Abstract
The eco-friendly biosynthesis of silver nanoparticles (AgNps) from bark extract of Albizia chevalier are reported here for their anti-proliferative, antibacterial and pollutant degradation potentials. The synthesized AgNps were characterized by FTIR spectroscopy, transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), energy dispersive X-rays spectrometry (EDS) and X-ray diffraction studies. The TEM and FESEM images show a monodispersed spherical shaped particles of approximately 30 nm. Crystalline peaks were obtained for the synthesized AgNps in XRD spectrum. The AgNps were investigated for in vitro anticancer and antibacterial activities and its potential to degrade 4-nitrophenol (4-NP) and congo red dye (CR). The MTT results shows a significant dose-dependent antiproliferation effect of the AgNps on the cell lines HepG2, MDA-MB-231 and MFC7. The effect was found more pronounced in MDA-MB-231 as compared to MFC-7 cell lines. The antibacterial results indicated 99 and 95% killing of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) respectively, after 24 h of incubation with the AgNps. The AgNps were found to speed up the reductive degradation of 4-NP and CR dye, which give an alternative route for the removal of toxic organic pollutants from the wastewater. The synthesized AgNps were not only used as a bactericidal and anticancer agent, but also effectively used for the reductive degradation of carcinogenic compounds which are listed as the priority pollutants. Therefore, AgNps have the potential for the treatment of various cancers, bacterial infections and for industrial detoxification of wastewater.

Abstract
BACKGROUND Medicinal plants and green synthesis of silver nanoparticles (AgNPs) have proven to be good sources of agents effective in the treatment of diabetes mellitus. The present study focused on the green synthesis of AgNPs from the aqueous leaf extract of Pouteria sapota in order to evaluate the in vitro and in vivo antidiabetic properties of this extract and the synthesized AgNPs. METHODS The AgNPs were biologically synthesized under ambient conditions from an aqueous leaf extract of P. sapota using the hot percolation method and were characterized using spectroscopic methods, X-ray diffraction, and scanning electron microscopy. The in vitro antidiabetic activity of the aqueous leaf extract and AgNPs was confirmed by non-enzymatic glycosylation of hemoglobin, glucose uptake by yeast cells following exposure of cells to 5 or 10 mmol/L glucose solution, and inhibition of α-amylase. Further, in vivo antidiabetic activity was assessed in streptozotocin-induced rats. Rats were treated with aqueous leaf extract (100 mg/kg) or AgNPs (10 mg/kg) for 28 days. Following treatment, rats were killed for biochemical and histopathological analysis of kidney and liver samples. RESULTS A significant reduction in blood sugar levels was noted in rats treated with leaf extract or AgNPs. Results of in vitro and in vivo analyses in rats treated with leaf extract or AgNPs show that both the extract and the biologically synthesized AgNPs have antidiabetic activity. CONCLUSION The aqueous leaf extract of P. sapota and AgNPs exhibited efficient antidiabetic activity in the rat model of diabetes and therefore could have potential for development for medical applications in the future.

Abstract
Herein, this research addresses an innovative approach for one-pot synthesis of highly stabilized silver nanorods in powder form at concentration as high as feasible to be proposed in large-scale production via cellulose nanocrystals (CNC). For the first time, CNC without any surface modification in the presence of alkali is acting as both reducing and stabilizing agent for assembling of Ag nanorods. Extraction of CNC from cotton is carried out as per to acid hydrolysis technique. Thorough assessments of Ag nanorods formation, structural and morphological characteristics of Ag nanorods were investigated by making use of UV-vis spectroscopy, TEM, DLS, AFM and X-ray diffraction (XRD) analysis. Also, the antibacterial activity and cytotoxicity of Ag nanorod were investigated. Research outputs signify that, Ag nanorods has been successfully prepared through an effectively approach by virtue of the textural feature of CNC as a mediator. Results revealed the great tendency of CNC toward reducing and stabilizing the as formed Ag nanorods even at high concentration. Results also demonstrated that Ag nanorods have not merely remarkably antibacterial activity towards Gram-positive and Gram-negative bacteria, but safe for using in human life, which exhibited no effect on eukaryotic cells.

Abstract
Gold nanoparticles (AuNPs) are widely used as a drug delivery vehicle, which can accumulate in the heart through blood circulation. Therefore, it is very important to understand the effect of AuNPs on the heart, especially under pathological conditions. In this study, we found that PEG-coated AuNPs attenuate β-adrenergic receptor (β-AR)-mediated acute cardiac hypertrophy and inflammation. However, both isoproterenol, a non-selective β-AR agonist, and AuNPs did not induce cardiac function change or cardiac fibrosis. AuNPs exerted an anti-cardiac hypertrophy effect by decreasing β1-AR expression and its downstream ERK1/2 hypertrophic pathway. Our results indicated that AuNPs might be safe and have the potential to be used as multi-functional materials (drug carrier systems and anti-cardiac hypertrophy agents).
