Abstract
Boring sponge infection affects growth, development and reduces the soft tissue weight of oysters. In this study, we investigated the effects of boring sponge on the activity of three antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GP)) in the mantle, and the production of reactive oxygen species (ROS) and potential genotoxicity in hemocytes of the Pacific oyster Magallana gigas. Our results showed a significant increase in ROS production and DNA damage in hemocytes. Notably, the activity of SOD, CAT, and GP in the mantle was not significantly affected by boring sponge infection. Collectively, these results suggest that sponge invasion may cause oxidative stress in Pacific oyster hemocytes through ROS overproduction.

Abstract
Hydroxypropyl methylcellulose (HPMC)-based microparticles and modified starch emulsions (OSA-MS) were loaded with resveratrol and characterized regarding their physicochemical and thermal properties. Both delivery systems were subject to an in vitro gastrointestinal digestion to assess the bioaccessibility of resveratrol. In addition, cell-based studies were conducted after in vitro digestion and cytotoxicity and oxidative stress were assessed. HPMC-based microparticles displayed higher average sizes (d) and lower polydispersity index (PDI) (d = 948 nm, PDI < 0.2) when compared to OSA-MS-based emulsions (d = 217 nm, PDI < 0.3). Both proved to protect resveratrol under digestive conditions, leading to an increase in bioaccessibility. Resveratrol-loaded HPMC-microparticles showed a higher bioaccessibility (56.7 %) than resveratrol-loaded emulsions (19.7 %). Digested samples were tested in differentiated co-cultures of Caco-2 and HT29-MTX, aiming at assessing cytotoxicity and oxidative stress, and a lack of cytotoxicity was observed for all samples. Results displayed an increasing antioxidant activity, with 1.6-fold and 1.4-fold increases over the antioxidant activity of free resveratrol, for HPMC-microparticles and OSA-MS nanoemulsions, respectively. Our results offer insight into physiological relevancy due to assessment post-digestion and highlight the protection that the use of micro-nano delivery systems can confer to resveratrol and their potential to be used as functional food ingredients capable of providing antioxidant benefits upon consumption.

Abstract
Introduction Atherosclerosis is a complicated cascade of inflammatory processes, oxidative stress, and apoptosis, making it the most prevalent cardiovascular disease. The onset and progression of cardiovascular diseases are greatly influenced by oxidative stress. Targeting oxidative stress is an effective strategy for treating such diseases. Marrubiin is a bioactive furan labdane diterpenoid acts as a strong antioxidant to protect against oxidative damage. This study aimed to investigate the protective effects of marrubiin against oxidative stress and apoptosis in a cellular model of the vascular system. Methods Human umbilical vein endothelial cells were treated with varying concentration of marrubiin and its IC50 value was determined. The antioxidant potential of marrubiin was assessed by measuring the intracellular level of glutathione (GSH) using a colorimetric technique. Since apoptosis plays a significant role in the plaque rupture, the study also evaluated the protective effects of marrubiin on the expression of key genes involved in apoptotic pathways. Results Cells treated with marrubiin showed increased GSH levels compared to cell therapy control cells, indicating marrubiin's ability to counteract the effects of TNF-α's on GSH levels. Furthermore real-time PCR analysis demonstrated that marrubiin upregulated Bcl-xl while downregulating caspase3 and Nox4 in treated cells. These findings suggest that marrubiin protects against apoptosis and oxidative stress. Conclusion Based on our findings, marrubiin is recommended as a preventive/therapeutic treatment for diseases caused by elevated intracellular reactive oxygen species levels in cardiovascular diseases.

Abstract
Inulin, a dietary fibre, is widely used as a prebiotic, sugar replacer, and texture modifier in the food industry. In this study, we have shown that irradiation affects the physicochemical properties of inulin, which in turn improves its biological functionality and feasibility as a functional ingredient in synbiotic foods. The biological functionality of 25 kGy-irradiated inulin (IRI) was assessed in terms of antioxidant capacity, protective action against intracellular ROS, and prebiotic activity. Antioxidant assays revealed that irradiated inulin had improved antioxidant activity, which was even greater than that of fructooligosaccharides. Furthermore, IRI was found to be comparatively more effective in maintaining low intracellular ROS levels. The in vitro fermentation studies showed that IRI had higher bifidogenic efficacy than fructooligosaccharides and unirradiated inulin. A synbiotic low-fat yogurt containing IRI (8.5 %) was prepared. In terms of sensory attributes, the developed product was comparable to a commercially available non-synbiotic and high-fat containing product.

Abstract
Guanine nucleotide binding protein (G protein) coupled receptor 17 (GPR17) plays crucial role in Glioblastoma multiforme (GBM) cell signaling and is primarily associated with reactive oxidative species (ROS) production and cell death. However, the underlying mechanisms by which GPR17 regulates ROS level and mitochondrial electron transport chain (ETC) complexes are still unknown. Here, we investigate the novel link between the GPR17 receptor and ETC complex I and III in regulating level of intracellular ROS (ROSi) in GBM using pharmacological inhibitors and gene expression profiling. Incubation of 1321N1 GBM cells with ETC I inhibitor and GPR17 agonist decreased the ROS level, while treatment with GPR17 antagonist increased the ROS level. Also, inhibition of ETC III and activation of GPR17 increased the ROS level whereas opposite function was observed with antagonist interaction. The similar functional role was also observed in multiple GBM cells, LN229 and SNB19, where ROS level increased in the presence of Complex III inhibitor. The level of ROS varies in Complex I inhibitor and GPR17 antagonist treatment conditions suggesting that ETC I function differs depending on the GBM cell line. RNAseq analysis revealed that ∼ 500 genes were commonly expressed in both SNB19 and LN229, in which 25 genes are involved in ROS pathway. Furthermore, 33 dysregulated genes were observed to be involved in mitochondria function and 36 genes of complex I-V involved in ROS pathway. Further analysis revealed that induction of GPR17 leads to loss of function of NADH dehydrogenase genes involved in ETC I, while cytochrome b and Ubiquinol Cytochrome c Reductase family genes in ETC III. Overall, our findings suggest that mitochondrial ETC III bypass ETC I to increase ROSi in GPR17 signaling activation in GBM and could provide new opportunities for developing targeted therapy for GBM.

Abstract
Mitochondrial dysfunction has been reported to be one of the main causes of many diseases including cancer, type2 diabetes, neurodegenerative disorders, cardiac ischemia, sepsis, muscular dystrophy, etc. Under in vitro conditions, Cytochrome C (Cyt C) maintains mitochondrial homeostasis and stimulates apoptosis, along with being a key participant in the life-supporting function of ATP synthesis. Hence, the medicinal importance of Cyt C as catalytic defense is immensely important in various mitochondrial disorders. Here, we have developed a nanomaterial via electrostatically conjugating oxidized single-wall carbon nanotube with Cyt C (Cyt C@cSWCNT) for the exogenous delivery of Cyt C. The chemical and morphological characterization of the developed Cyt C@cSWCNT was done using UV-vis, FTIR, XPS, powder XRD, TGA/DSC, TEM, etc. The developed Cyt C@cSWCNT exhibited bifunctional catalase and peroxidase activity with Km (∼ 642.7 μM and 351.6 μM) and Vmax (∼0.33 μM/s and 2.62 μM/s) values, respectively. Also, through this conjugation Cyt C was found to retain its catalytic activity even at 60 °C, excellent catalytic recyclability (at least up to 3 times), and wider pH activity (pH = 3 to 9). Cyt C@cSWCNT was found to promote intracellular ROS quenching and maintain mitochondrial membrane potential and cellular membrane integrity via Na+/K+ ion homeostasis during the H2O2 stress. Overall the present strategy provides an alternative approach for the exogenous delivery of Cyt C which can be used as nano catalytic medicine.

Abstract
Intracellular bacterial infections pose enormous challenges to food safety and public health. Antibiotic-based polymer prodrugs have been used to treat intracellular bacterial infection. However, the overuse of antibiotics may lead to the emergence of antibiotic resistance. In this work, we aimed to develop antibiotic-free pH-responsive polymeric prodrugs to combat intracellular S. aureus infection. Amphiphilic poly(ethylene glycol)-b-poly[(3-phenylprop-2-ene-1,1-diyl)bis(oxy)bis(enthane-2,1- diyl)diacrylate] (PEG-b-PCAE) was obtained by radical polymerization and they could self-assemble to form micelles. PEG-b-PCAE micelles could uptake by macrophage. Upon exposure to the acidic phagolysosome, PEG-b-PCAE micelles could release cinnamaldehyde (CA) through hydrolysis of the acetal linkage. PEG-b-PCAE could kill intracellular bacteria by damaging the bacterial membrane. Furthermore, PEG-b-PCAE micelles could generate reactive oxygen species (ROS) in macrophages and subsequently activate immune system to clear bacteria by inducing macrophages differentiation to M1 phenotype. PEG-b-PCAE micelles could accelerate the wound healing process of the S. aureus-infected model in vivo. It is anticipated that multifunctional antibiotic-free PEG-b-PCAE micelles with intrinsic antibacterial activities hold promise for improved outcomes in intracellular S. aureus infections.

Abstract
In this study, substance P, an antioxidant peptide of tachykinin, was identified using bioinformatics tools from the earlier established muscle transcriptome of a freshwater murrel Channa striatus and the peptide was named RM12. The antioxidant properties of RM12 were screened using various colorimetric assays. The toxicity of RM12 was experimented using fish erythrocytes, and it is observed that the maximum concentration (320 μM) of RM12 was found to have 15 or 20% of hemolytic activity; however, it was not significant with other tested concentrations (10, 20, 40, 80, and 160 μM). Further, the in vivo antioxidant properties of RM12 were experimented on zebrafish embryo, the intracellular ROS level was estimated by 5 mM H2O2 stress in the zebrafish embryo, and inhibition of apoptosis was evaluated. The antioxidant enzymes were extracted from the H2O2-stressed zebrafish embryo, and the intracellular ROS was eliminated due to RM12. Collectively, the experiment showed that the substance P from the freshwater murrel C. striatus possessed potent antioxidant properties; thus, it can further be focused to develop it as antioxidant molecule in aquaculture organisms.

Abstract
Lignin is a complex phenolic biopolymer present in plant cell walls and a by-product of the cellulose pulping industry. Lignin has functional properties, such as antioxidant activity, that make it a potential natural active ingredient for health-care products. However, not all safety aspects of lignin fractions have been adequately investigated. Herein, we evaluated the antioxidant and genotoxic potential of two hardwood kraft lignins (F3 and F5). The chemical characterization of F3 and F5 demonstrated their thermal stability and the presence of different phenolic units, while the DPPH assay confirmed the antioxidant activity of these lignin fractions. Despite being antioxidants in the DPPH assay, F3 and F5 were capable of generating intracellular reactive oxygen species (ROS) and subsequently causing oxidative DNA damage (Comet assay) in HepG2 cells. The biological relevance of the DPPH assay might be uncertain in some cases; therefore, we suggest combining in chemico tests with biological system-based tests to determine efficacy and safety levels of lignins and define appropriate applications of lignins for consumer products. Moreover, kraft lignins obtained by acid precipitation may pose risks to human health; however, as genotoxicity is not the sole endpoint of toxicity required in hazard assessments, additional toxicological evaluations are needed.

Abstract
Peracetic acid (PAA) has been widely used as a disinfectant in many industries; its use in poultry processing is steadily increasing. However, information related to the potential inhibitory effect of PAA solutions (PAA and H2O2) on biological wastewater treatment processes used by the poultry processing industry is extremely limited. The work reported here assessed the long-term effect of PAA solution on aerobic degradation and nitrification in three bioreactors fed with poultry processing wastewater by quantifying the extent of COD removal and nitrification rates. Changes in culture viability, intracellular reactive oxygen species (ROS), and microbial community structure were also evaluated. COD removal and nitrification were not affected by H2O2 and PAA solutions added to the wastewater before feeding (indirect addition). However, both processes were significantly affected by high levels of H2O2 (i.e., 27 mg/L) and PAA solution (i.e., 60/8.4 mg/L PAA/H2O2) directly added to the reactors. Directly added PAA/H2O2 at 40/5.6 mg/L was the lowest dose resulting in nitrification inhibition. Fast recovery of COD removal and nitrification was observed when direct addition of H2O2 and PAA solution ended. Cell viability measurements revealed that the negative impact on nitrification was predominantly attributed to enzyme inhibition rather than to loss of cell viability. The impact on nitrification was not related to intracellular ROS levels. Microbiome analysis showed major shifts in community composition during the long-term addition of H2O2 and even more with PAA addition. No significant time-trend change in the relative abundance of ammonia-oxidizing bacteria or nitrite-oxidizing bacteria was observed, further supporting the conclusion that the negative impact on nitrification was attributed mainly to enzyme inhibition.

Abstract
Although a mitochondrial redox-cycling superoxide-generating mechanism for the cardiotoxicity of doxorubicin was suggested from experiments with isolated mitochondria, its occurrence and contribution to cytotoxicity in intact cardiomyocytes is not fully established. Therefore, we determined the immediate and delayed effects of doxorubicin on the generation of reactive oxygen species (ROS) and cytotoxicity in differentiated H9c2 cardiomyocytes. Although relatively short incubations (3 or 6 h) with 1 or 5 µM doxorubicin did not acutely decrease cell survival, exposure to 5 µM doxorubicin for 3 h was sufficient to cause a significant delayed decrease in cell survival after an additional 24 h without doxorubicin. Mitochondrial superoxide generation was observed to increase within 30 min of incubation with 5 µM doxorubicin. Increased intracellular ROS generation, decreased mitochondrial metabolic activity, and decreased mitochondrial membrane potential (MMP) were observed after more extended periods (6-12 h). Overall, these observations support that the toxicity of doxorubicin to differentiated cardiomyocytes involves acute mitochondrial superoxide generation with subsequent intracellular ROS generation, mitochondrial dysfunction, and cell death.

Abstract
Lipid production in microalgae can be induced by various stress factors. However, stress induced lipid accumulation requires considerable time leading to the decrease in lipid productivity. Here, we attempted to increase the lipid productivity while maintaining the high growth of Ettlia sp. by optimizing nitrogen concentration and UV exposure in a continuous culture. The biomass and lipid productivities of Ettlia sp. cultured with 150 mg N L-1 and UV-A added PAR were 1.67 ± 0.08 g L-1 d-1 and 0.55 ± 0.05 g L-1 d-1, respectively. Lipid productivity and lipid content were around 43.7% and 33.7% higher, respectively in UV-A treatment compared to the control. Moreover, gene-expression patterns related to antioxidant defense and intracellular ROS levels indicated that UV-A affected certain ROS and antioxidants pathways and successfully induced the lipid accumulation in Ettlia sp. This strategy to activate lipid accumulation can be applied in other microalgae without affecting their growth.

Abstract
In the present study, a series of forty-five asymmetrical meta-methoxylated diarylpentanoids have been synthesized, characterized and evaluated for their in-vitro anti-cancer potential. Among the forty-five analogs, three compounds (20, 33 and 42) have been identified as lead compounds due to their excellent inhibition against five human cancer cell lines including SW620, A549, EJ28, HT1080 and MCF-7. Structure-activity relationship study on cytotoxicity of tested compounds suggested that the presence of meta-oxygenated phenyl ring played a critical role in enhancing their cytotoxic effects. Compounds 33 and 42 in particular, exhibited strongest cytotoxicity against tested cell lines with the IC50 values ranging from 1.1 to 4.3 μM. Subsequent colony formation assay on SW620 cell line showed that both compounds 33 and 42 possessed strong anti-proliferative activity. In addition, flow cytometry based experiments revealed that these compounds could trigger intracellular ROS production thus inducing G2/M-phase cell arrest and apoptosis. All these results suggested that poly meta-oxygenated diarylpentnoid is a promising scaffold which deserved further modification and investigation in the development of natural product-based anti-cancer drug.

Abstract
Reactive oxygen species (ROS) are chemically reactive oxygen containing molecules. ROS consist of radical oxygen species including superoxide anion (O2 •-) and hydroxyl radical (•OH) and non-radical oxygen species such as hydrogen peroxide (H2O2), singlet oxygen (O2). ROS are generated by mitochondrial oxidative phosphorylation, environmental stresses including UV or heat exposure, and cellular responses to xenobiotics ( Ray et al., 2012 ). Excessive ROS production over cellular antioxidant capacity induces oxidative stress which results in harmful effects such as cell and tissue damage. Sufficient evidence suggests that oxidative stresses are involved in cancers, cardiovascular disease, and neurodegenerative diseases including Alzheimer's disease and Parkinson disease (Waris and Ahsan, 2006). Though excessive level of ROS triggers detrimental effects, ROS also have been implicated to regulate cellular processes. Since ROS function is context dependent, measurement of ROS level is important to understand cellular processes (Finkel, 2011). This protocol describes how to detect intracellular and mitochondrial ROS in live cells using popular chemical fluorescent dyes.

Abstract
A high sensitive and selective hydrogen peroxide (H2O2) biosensor was fabricated on the basis of reduced hemoglobin (Hb) and single-walled carbon nanotubes (SWCNTs) for detecting the release of H2O2 from living HepG2 cancer cells in the process of the in situ biosynthesis of ZnO quantum. The modification of carbon fiber microelectrode (CFME) was carried out by physical adsorption. By the scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), the dense cover of surface and successful immobilization were characterized. Electrochemical investigation demonstrates that the as-prepared modified microelectrode showed a quasi-reversible process toward the reduction of H2O2, which exhibited a linear range from 0.51 to 10.6 μM, with a limit of detection of 0.23 μM. This microelectrode biosensor was applied for the quantification of the change of H2O2 concentration released from HepG2 cells through the in situ biosynthesis of ZnO quantum dots, which was further confirmed by the fluorescence staining.

Abstract
Platelet is an important cell contributing to hemostasis and immunity. Bacterial lipopolysaccharide (LPS), mainly functioning by stimulating toll-like receptor 4 (TLR4), mediates platelet activation and sepsis. However, the inter-relationship between these players in sepsis remains unknown. We found that the aggregation of platelets was enhanced in complete blood of sepsis patients than that of healthy donors. PRP isolated from complete blood of healthy donors was used in the following study to filter out the interference of irrelevant cells. The results shown that the maximum aggregation rate (MAR) was significantly higher in LPS-challenged PRP model than that of controls, and administration of the specific TLR4 inhibitor, TAK242, reduced the MAR in this model. LPS promoted P-selectin expression and intracellular ROS production, and both TAK242 and N-acetyl-L-cysteine (NAC) could depressed the LPS-induced increase of P-selectin and intracellular ROS. H2O2 administration increased P-selectin expression partially but had little effect on intracellular ROS, thought it increased mitochondrial damage. In vivo, LPS increased both intracellular ROS and CD62P comparing with that of controls, effects that were prevented by TAK242. Furthermore, platelet aggregation through LPS-TLR4 pathway was involved in AKT, PKC and p38 phosphorylation but not cGMP/cAMP pathway. In conclusion, this study shows that intracellular ROS, not extracellular ROS such as H2O2, plays a crucial role in facilitating platelet aggregation via LPS/TLR4 pathway, and this process was involved in AKT, PKC and p38 phosphorylation but not cGMP/cAMP pathway. The results would helpful for understanding the role of intracellular ROS and LPS-TLR4 pathway in platelet aggregation.

Abstract
Oxidative stress possesses a key role in the onset and development of cardiovascular diseases (CVDs), thus it can be an efficient target to tackle such ailment. Marrubiin, a bioactive diterpene, is a potent antioxidant against oxidative stress. Herein, we aimed to formulate marrubiin loaded solid lipid nanoparticles (SLNs) to improve its pharmacokinetics and bioavailability and also to investigate free drug and formulation's protective impact against intracellular reactive oxygen species (ROS) generation in HUVECs. Marrubiin-SLNs were formulated using hot homogenization/solidification method and then were subjected to physicochemical characterizations, i.e. size, zeta potential, morphology, polydispersity index (PDI), encapsulation efficiency (% EE), drug loading/content and physical stability assessments. MTT assay was performed to study the cytotoxicity of the intact and SLN incorporated marrubiin on HUVECs. Further, the antioxidant property of marrubiin and formulations was evaluated using DPPH radical scavenging assay and their protective effect against TNF-α induced oxidative stress was assessed by the means of intracellular ROS assessment, and also apoptosis/necrosis, cell cycle, and DNA fragmentation assays. Electron microscopy analysis showed spherical monodispersed SLNs with the size less than 100 nm, particle/zeta size analyses also approved the size of particles with a zeta potential of -1.28 ± 0.17 mV. Results also showed high EE (98%), drug loading (31.74 mg/g) with 3.15% drug content. In vitro release studies revealed about 90% of marrubiin cumulative release during 24 h. The stability of marrubiin-SLNs in terms of size, zeta potential, polydispersity index, EE and drug leakage was approved. Marrubiin antioxidant stability after formulation was approved by DPPH analysis. MTT cell survival assay showed no significant cytotoxicity after 24 h and 48 h. Intracellular ROS detection assay revealed that marrubiin and marrubiin-SLNs, play protective effect against TNF-α induced oxidative stress in HUVECs which was further approved by apoptosis assessment. Conclusively, based on our findings, marrubiin nanoparticles are proposed as a preventive/therapeutic remedy against disorders elicited by increased levels of intracellular ROS in CVDs.

Abstract
The potential toxicity of pharmaceuticals towards aquatic invertebrates is still poorly understood and sometimes controversial. This study aims to document the in vitro genotoxicity and immunotoxicity of psychotropic drugs and antibiotics on Mytilus edulis. Mussel hemocytes were exposed to fluoxetine, paroxetine, venlafaxine, carbamazepine, sulfamethoxazole, trimethoprim and erythromycin, at concentrations ranging from μg/L to mg/L. Paroxetine at 1.5 μg/L led to DNA damage while the same concentration of venlafaxine caused immunomodulation. Fluoxetine exposure resulted in genotoxicity, immunotoxicity and cytotoxicity. In the case of antibiotics, trimethoprim was genotoxic at 200 μg/L and immunotoxic at 20 mg/L whereas erythromycin elicited same detrimental effects at higher concentrations. DNA metabolism seems to be a highly sensitive target for psychotropic drugs and antibiotics. Furthermore, these compounds affect the immune system of bivalves, with varying intensity. This attests the relevance of these endpoints to assess the toxic mode of action of pharmaceuticals in the aquatic environment.

Abstract
Nostoc commune is a terrestrial benthic blue-green alga that often forms an extended mucilaginous layer on the soil, accumulates on stones and mud in aquatic environments. Reduced-scytonemin (R-scy), isolated from N. commune Vaucher, has been shown to suppress the human T-lymphoid Jurkat cell growth. To reveal the mechanisms underlying the R-scy-mediated inhibition of Jurkat cell growth, we examined cell morphology, DNA fragmentation, and microtubule-associated protein light chain 3 (LC3) modification in these cells. We observed multiple vacuoles as well as the conversion of LC3-I to LC3-II in R-scy-treated cells. These results suggest that the R-scy induced Jurkat cell growth inhibition is attributable to the induction of type II programmed cell death (PCD II; autophagic cell death or autophagy). We further examined the mechanisms underlying R-scy-induced PCDII. The cells treated with R-scy produced large amounts of reactive oxygen species (ROS), leading to the induction of mitochondrial dysfunction. However, the elimination of R-scy-induced ROS by treatment with N-acetyl-L-cysteine (NAC) markedly opposed R-scy-induced PCDII. Based on these results, we conclude that ROS formation plays a critical role in R-scy-induced PCDII.
