Abstract
Neonicotinoids are the most widely used pesticides in the world. However, research studies have shown that it can affect the cognitive abilities and health of non-target bees and other wild pollinators by inducing DNA damage, apoptosis and mitochondrial damage, injure to its central nervous system, and it is even developmentally neurotoxic to mammals and humans, with mitochondria being an important target of neonicotinoids. Therefore, this article reviews the role of mitochondrial morphology, calcium ions (Ca2+) homeostasis, respiratory function, apoptosis, and DNA damage in neonicotinoids-induced systemic toxicity. Additionally, it evaluates the protective effects of various active substances including vitamin C, N-acetylcysteine (NAC), curcumin (CUR), glutathione reduced (GSH), caffeic acid phenethyl ester (CAPE), resveratrol, and thymoquinone (TQ) on neonicotinoids-induced toxicity. This review manuscript found that mitochondria are important targets to neonicotinoids. Neonicotinoids can cause DNA damage, apoptosis, protein oxidation, and lipid peroxidation in non-target organisms by altering mitochondrial Ca2+ homeostasis, inhibiting mitochondrial respiration, and inducing reactive oxygen species (ROS) production. Several active substances (vitamin C, NAC, CUR, GSH, resveratrol, CAPE, and TQ) play a protective role against neonicotinoid-induced systemic toxicity by inhibiting ROS signaling pathways, apoptosis, and lipid peroxidation. This review manuscript emphasizes the importance and urgency of the development of neonicotinoid antidotes, emphasizes the prospect of the application of targeted mitochondrial antidotes, and prospects the development of neonicotinoid antidotes in order to provide some strategies for the prevention of neonicotinoid toxicity.

Abstract
Inflammation is major symptom of the innate immune response by infection of microbes. Macrophages, one of immune response related cells, play a role in inflammatory response. Recent studies reported that various natural products can regulate the activation of immune cells such as macrophage. Sargassum horneri (Turner) C. Agardh is one of brown algae. Recently, various seaweeds including brown algae have antioxidant and anti-inflammatory effects. However, anti-inflammatory effects of Sargassum horneri (Turner) C. Agardh are still unknown. In this study, we investigated anti-inflammatory effects of ethanolic extract of Sargassum horneri (Turner) C. Agardh (ESH) on RAW 264.7 murine macrophage cell line. The ESH was extracted from dried Sargassum horneri (Turner) C. Agardh with 70% ethanol and then lyophilized at -40 °C. ESH was not cytotoxic to RAW 264.7, and nitric oxide (NO) production induced by LPS-stimulated macrophage activation was significantly decreased by the addition of 200 μg/mL of ESH. Moreover, ESH treatment reduced mRNA level of cytokines, including IL-1β, and pro-inflammatory genes such as iNOS and COX-2 in LPS-stimulated macrophage activation in a dose-dependent manner. ESH was found to elicit anti-inflammatory effects by inhibiting ERK, p-p38 and NF-κB phosphorylation. In addition, ESH inhibited the release of IL-1β in LPS-stimulated macrophages. These results suggest that ESH elicits anti-inflammatory effects on LPS-stimulated macrophage activation via the inhibition of ERK, p-p38, NF-κB, and pro-inflammatory gene expression.

Abstract
The role of redox molecules, such as NO and ROS, as key mediators of immunity has recently garnered renewed interest and appreciation. To regulate immune responses, these species trigger the eradication of pathogens on the one hand and modulate immunosuppression during tissue-restoration and wound-healing processes on the other. In the acidic environment of the phagosome, a variety of RNS and ROS is produced, thereby providing a cauldron of redox chemistry, which is the first line in fighting infection. Interestingly, fluctuations in the levels of these same reactive intermediates orchestrate other phases of the immune response. NO activates specific signal transduction pathways in tumor cells, endothelial cells, and monocytes in a concentration-dependent manner. As ROS can react directly with NO-forming RNS, NO bioavailability and therefore, NO response(s) are changed. The NO/ROS balance is also important during Th1 to Th2 transition. In this review, we discuss the chemistry of NO and ROS in the context of antipathogen activity and immune regulation and also discuss similarities and differences between murine and human production of these intermediates.

Abstract
Viral infections of the heart are a causative factor of myocarditis as well as of sudden, unexpected deaths of children, yet the mechanisms of pathogenesis remain unclear, in part due to the relatively few animal models of virus-induced myocarditis. In the current study, we examined the ability of polytropic murine retroviruses to infect the heart and induce cardiac dysfunction. In situ hybridization and immunohistochemistry analysis detected virus-infected cardiomyocytes and macrophages in the heart. A significant decrease in left ventricle function, as measured by fractional shortening, was detected in mice infected with the neurovirulent retrovirus Fr98 but not in mice infected with the nonneurovirulent retrovirus Fr54. Virus infection was not associated with consistent findings of fibrosis or substantial cellular infiltrate. Fr98-induced left ventricle dysfunction was associated with a higher virus load, increased mRNA expression of the macrophage marker F4/80, increased chemokine production, and a small number of apoptotic cells in the heart.

Abstract
Ongoing coxsackievirus B3 (CVB3) myocarditis is characterized by persistence of viral RNA and chronic inflammation primarily mediated by macrophages and T cells. Activated macrophages produce anti-viral effector molecules comprising reactive nitrogen intermediates; however, reactive nitrogen intermediates also contribute to host tissue damage. Controlled activation of macrophages depends on interferon (IFN)-gamma and interleukin (IL)-10. To evaluate mechanisms involved in CVB3-induced pathogenesis of myocarditis, we determined the relationship of inducible nitric-oxide synthase (iNOS) mRNA expression with IFN-gamma and IL-10 secretion during CVB3 infection in different mouse strains. We found in susceptible A.BY/SnJ mice that develop ongoing myocarditis, a low and delayed IFN-gamma secretion and highly diminished IL-10 production compared with resistant C57BL/6 mice. Consequently, iNOS mRNA synthesis was delayed but clearly prolonged in susceptible mice. IL-10 gene-deficient mice confirmed the regulatory role of IL-10 in the outcome of CVB3 myocarditis. These mice did not establish a persistent cardiac infection and revealed IFN-gamma secretion kinetics similar to resistant mice but showed a slightly elongated cardiac iNOS mRNA expression resulting in extended myocarditis. We conclude that coordinated secretion of IFN-gamma and IL-10 is crucial for the effective resolution of CVB3 myocarditis. Moreover, lack of regulatory IL-10 leads to uncontrolled iNOS mRNA production, thus contributing to ongoing myocardial injury.

Abstract
The utility of adenoviral vectors, currently used in cardiovascular gene transfer protocols, is limited by the brevity of transgene expression and by antiadenoviral immune responses. The effect of preexisting antiadenoviral immunity on intracardiac gene transfer or its modulation by nitric oxide is unknown. Adenoviral vectors, expressing the firefly luciferase gene (AdLuc) or the human nitric oxide synthase 3 (NOS3) gene (AdNOS3), were infused into the great cardiac vein of naive pigs or immunized pigs. Pigs were immunized by intravenous injection of control virus AdRR5 and the resulting neutralizing antibody titers (median, 1:178; p < 0.0001 vs. baseline) were similar to preexisting titers in 54% of randomly selected coronary artery bypass graft patients. In naive animals distribution of transgene expression in the left ventricular free wall was focal. In immunized pigs myocardial luciferase expression 3 days after AdLuc gene transfer was more than 1000-fold lower than in naive pigs, whereas no change in NOS3 transcript levels was detected after AdNOS3 gene transfer. Severe, grade III-IV mononuclear cell infiltration and myocyte apoptosis were observed in four of five AdLuc-infected, immunized animals, compared with low-level inflammation and apoptosis in five of six AdNOS3-infected pigs. Coinfusion of AdLuc and AdNOS3 in immunized pigs resulted in spatially colocalized transgene expression, reduced T cell-mediated inflammation, and myocyte apoptosis and was associated with 200-fold greater median reporter transgene expression levels in the subendocardium (1.0 x 10(3) light units [LU]/mg protein, n = 8, vs. 4.5 x 10(1) LU/mg protein in AdLuc- and AdRR5-coinfected pigs, n = 7, p = 0.02). Preexisting antiadenoviral immunity abrogates myocardial gene expression in pigs and is associated with severe inflammation and myocyte apoptosis. Intracardiac NOS3 gene transfer may reduce these barriers to adenovirus-mediated myocardial gene transfer.

Abstract
OBJECTIVES This study was designed to investigate the roles of Fas/FasL pathway in myocardial damage in murine acute myocarditis caused by Coxsackie virus B3 (CVB3). BACKGROUND Cardiac myocyte apoptosis rarely occurs in murine acute myocarditis caused by CVB3. Fas/FasL belong to the tumor necrosis factor receptor/ligand superfamily of costimulatory molecules and are known to play a critical role in the induction of apoptosis, as well as in the cytotoxicty mediated by T-cells and natural killer cells. METHODS We first analyzed the expression of Fas on cardiac myocytes in vivo and in vitro. Second, we examined the development of myocardial damage, in C3H/He mice treated with an anti-FasL monoclonal antibody (mAb), and in C3H/He-lpr/lpr mice and C3H/He-gld/gld mice infected with CVB3. Third, to investigate the effects of anti-FasL mAb treatment on the activation of the infiltrating cells, we examined the expression of interferon (IFN)-gamma and interleukin (IL)-2 as activation markers in the heart of mice by semiquantitative polymerase chain reaction. RESULTS Fas was markedly induced on cardiac myocytes with acute myocarditis. Myocardial inflammation was decreased in mice treated with anti-Fas L mAb, C3H/He-lpr/lpr mice and C3H/He-gld/gld mice. Anti-FasL mAb-treatment also decreased the expression of IFN-gamma, IL-2, inducible nitric oxide synthase and CVB3 genomes in myocardial tissue. CONCLUSIONS Our findings strongly suggested that the Fas/FasL pathway played a critical role in the development of massive myocardial necrosis through activation of infiltrating cells, and raise the possibility of immunotherapy by blocking the Fas/FasL pathway to prevent myocardial damage and improve the prognosis of patients with viral myocarditis.

Abstract
Increased expression of inducible nitric oxide synthase (iNOS) has been found in inflammatory myocardial disease and increased production of nitric oxide (NO) has both an inhibitory effect on virus replication and a cytotoxic effect on host cells. To investigate the relationship between severity of enteroviral myocarditis and iNOS expression, a characterised murine model was infected with either cardiovirulent or an attenuated Coxsackievirus B3 and myocardial samples were collected on Day 7. The ability of these viruses to induce NOS expression was compared by measurement of iNOS enzyme activity and localisation of iNOS protein or peroxynitrite, a product of excessive NO production. In accordance with previous reports, high expression of iNOS was detected in mice infected with the cardiovirulent virus. The iNOS protein was located mainly in infiltrating macrophages in and around foci of necrotic myofibres where viral genomic RNA was detected. In contrast, the level of iNOS expression was significantly lower in mice infected with the attenuated virus. This correlates with fewer and smaller myocarditic lesions and less infiltrating cells in the heart. iNOS was not detected in mock-infected mice by the above assays. These findings suggest that one mechanism of attenuation may be associated with the reduced ability of the variant to induce NOS expression in the heart. This also confirms a cytotoxic role for NO in the pathogenesis of Coxsackievirus B3-induced myocarditis.

Abstract
BACKGROUND Human rhinovirus (HRV) infections are the predominant cause of the common cold and are associated with exacerbations of asthma. Nitric oxide (NO) may play an important role in host defense by means of its potent antiviral properties. OBJECTIVE We sought to determine whether epithelial expression of type 2 nitric oxide synthase (NOS 2), which produces NO, is induced on rhinovirus infection in vitro and in vivo. METHODS Primary cultures of human airway epithelial cells were infected with HRV-16, and NOS 2 mRNA expression was assessed by conventional and real-time RT-PCR and NOS 2 protein by using Western blot analysis. Human subjects were also infected with HRV-16 in vivo, and mRNA for NOS 2 was assessed in nasal epithelial scrapings obtained before and after infection. RESULTS NOS 2 mRNA levels increased within 8 hours after HRV-16 infection of cultured cells and remained elevated up to 48 hours after infection. NOS 2 protein was elevated at 24 hours. Induction of NOS 2 did not occur with UV-inactivated HRV-16 but could be reproduced by using double-stranded RNA, indicating that induction was dependent on viral replication. Increased NOS 2 expression was also observed in nasal epithelial scrapings during symptomatic colds. CONCLUSION Increased epithelial expression of NOS 2 mRNA occurs as part of the host response to HRV infection in vitro and in vivo. Given the antiviral effects of NO, we speculate that increased host production of NO may play an important role in host defense during HRV infections.

Abstract
Myocarditis is an acquired form inflammatory heart muscle disease, manifested as acute and chronic conditions. While many etiologies have been reported, the most common cause of this disease is infection, primarily viral. Typically, the specific causative agent(s) and mechanism(s) are elusive. Over the past several years, various new findings have added to our understanding of myocarditis. These include the identification of adenoviruses as important causative agents, a new receptor protein likely to play an important role in the virulence of certain agents affecting the myocardium, and the effect of viruses on the cardiac cytoskeleton. This report reviews the current understanding of myocarditis, proposes a hypothesis about the long-term sequelae, and suggests possible new therapeutic strategies.
