Abstract
Hydrogen peroxide (H2O2) is a signaling molecule that has the capacity to control a variety of biological processes in organisms. Cancer cells release more H2O2 during abnormal tumor growth. There has been a considerable amount of interest in utilizing H2O2 as a biomarker for the diagnosis of cancer tissue. In this study, an electrochemical sensor for H2O2 was constructed based on 3D reduced graphene oxide (rGO), MXene (Ti3C2), and multi-walled carbon nanotubes (MWCNTs) composite. Three-dimensional (3D) rGO-Ti3C2-MWCNTs sensor showed good linearity for H2O2 in the ranges of 1-60 μM and 60 μM-9.77 mM at a working potential of -0.25 V, with sensitivities of 235.2 µA mM-1 cm-2 and 103.8 µA mM-1 cm-2, respectively, and a detection limit of 0.3 µM (S/N = 3). The sensor exhibited long-term stability, good repeatability, and outstanding immunity to interference. In addition, the modified electrode was employed to detect real-time H2O2 release from cancer cells and cancer tissue ex vivo.

Abstract
![]()
Nitric oxide (•NO) is one of the prominent
free
radicals, playing a pivotal role in breast cancer progression. Hyaluronic
acid (HA) plays an essential role in neutralizing free radicals in
tumor tissues. However, its interactions with nitric oxide have not
been thoroughly investigated. Hence, this study attempts to understand
the mechanism of these interactions and the different effects on the
intracellular •NO levels and migration of breast
cancer cells. The affinity of HA to scavenge •NO
was investigated alongside the accompanying changes in specific physico-chemical
properties and the further effects on the •NO-induced
attachment and migration of the breast cancer cell lines, MDA-MB-231
and HCC1806. The reaction of the nitrogen dioxide radical, formed
via •NO/O2 interactions, with HA initiated
a series of oxidative reactions, which, in the presence of •NO, induce the fragmentation of the polymeric chains. Furthermore,
these interactions were found to hinder the NO-induced migration of
cancer cells. However, the NO-induced HA modification/fragmentation
was inhibited in the presence of hemin, a NO-scavenging compound.
Collectively, these results help toward understanding the involvement
of HA in the •NO-induced cell migration and suggest
the possible modification of HA, used as one of the main materials
in different biomedical applications.

Abstract
Nitric oxide (NO) and NO synthases (NOSs) are crucial factors in many pathophysiological processes such as inflammation, vascular/neurological function, and many types of cancer. Noninvasive imaging of NO or NOS can provide new insights in understanding these diseases and facilitate the development of novel therapeutic strategies. In this review, we will summarize the current state-of-the-art multimodality imaging in detecting NO and NOSs, including optical (fluorescence, chemiluminescence, and bioluminescence), electron paramagnetic resonance (EPR), magnetic resonance (MR), and positron emission tomography (PET). With continued effort over the last several years, these noninvasive imaging techniques can now reveal the biodistribution of NO or NOS in living subjects with high fidelity which will greatly facilitate scientists/clinicians in the development of new drugs and/or patient management. Lastly, we will also discuss future directions/applications of NO/NOS imaging. Successful development of novel NO/NOS imaging agents with optimal in vivo stability and desirable pharmacokinetics for clinical translation will enable the maximum benefit in patient management.

Abstract
Information regarding vagal innervation in the cardiac ventricle is limited and the direct effect of vagal stimulation on ventricular myocardial function is controversial. We have recently provided indirect evidence that the anti-fibrillatory effect of vagus nerve stimulation on the ventricle is mediated by nitric oxide (NO). The aim of this study was to provide direct evidence for the release of nitric oxide in the cardiac ventricle during stimulation of the efferent parasympathetic fibres of the cervical vagus nerve. The isolated innervated rabbit heart was employed with the use of the NO fluorescent indicator 4,5-diaminofluorescein diacetate (DAF-2 DA) during stimulation of the cervical vagus nerves and acetylcholine perfusion in the absence and presence of the non-specific NO synthase inhibitor NG-nito-L-arginine (L-NNA) and the neuronal NO synthase selective inhibitor 1-(2-trifluormethylphenyl)imidazole (TRIM). Using the novel fluorescence method in the beating heart, we have shown that NO-dependent fluorescence is increased by 0.92 +/- 0.26, 1.20 +/- 0.30 and 1.91 +/- 0.27% (during low, medium and high frequency, respectively) in the ventricle in a stimulation frequency-dependent manner during vagus nerve stimulation, with comparable increases seen during separate stimulation of the left and right cervical vagus nerves. Background fluorescence is reduced during perfusion with L-NNA and the increase in fluorescence during high frequency vagal stimulation is inhibited during perfusion with both L-NNA (1.97 +/- 0.35% increase before L-NNA, 0.00 +/- 0.02% during L-NNA) and TRIM (1.78 +/- 0.18% increase before TRIM, -0.11 +/- 0.08% during TRIM). Perfusion with 0.1 microM acetylcholine increased NO fluorescence by 0.76 +/- 0.09% which was blocked by L-NNA (change of 0.00 +/- 0.03%) but not TRIM (increase of 0.82 +/- 0.21%). Activation of cardiac parasympathetic efferent nerve fibres by stimulation of the cervical vagus is associated with NO production and release in the ventricle of the rabbit, via the neuronal isoform of nitric oxide synthase.

Pflugers Arch 2008; 456:635-45.

Abstract
4,5-Diaminofluorescein (DAF-2) has been used to measure nitric oxide (NO) activity from a variety of preparations. The aim of this study was to develop a method to assess changes in NO fluorescence using DAF-2 in isolated rabbit hearts (2.0-2.5 kg, n = 8). Hearts were perfused in constant flow Langendorff mode and instrumented to record aortic perfusion pressure, left ventricular pressure and left ventricular epicardial fluorescence using a bifurcated light guide at excitation wavelengths of 470 +/- 10, 480 +/- 10, 490 +/- 10 and 500 +/- 10 nm collected at 535 nm. DAF-2 DA was loaded using a single bolus 150-microl (1 micromol) injection. Changes in NO-dependent fluorescence were determined using the NO donor sodium nitroprusside (SNP: 100 microM), NO-dependent vasodilator bradykinin (BK: 100 microM) and non-specific NO synthase inhibitor NG-nitro-L-arginine (LNA: 200 microM) before and after loading hearts with DAF-2 DA. Before loading, these agents did not alter epicardial fluorescence. After loading, SNP, BK and LNA produced a consistent change in each excitation wavelength. Together, this suggests that change in fluorescence represents changes in the level of NO. SNP and BK increased whilst LNA significantly decreased left ventricular epicardial NO-dependent fluorescence. At the excitation wavelength of 490 nm, SNP and BK increased fluorescence by 104.7 +/- 18.7 mV (1.1 +/- 0.2%) and 150.7 +/- 26.1 mV (1.5 +/- 0.3%) respectively, whilst LNA significantly decreased fluorescence by 90.3 +/- 17.0 mV (-0.9 +/- 0.2%). Changing the rate of aortic perfusion did not alter fluorescence suggesting that changes in aortic perfusion pressure per se do not contribute to the changes in DAF-2 fluorescence seen with SNP, BK or LNA. Our data suggest that DAF-2 DA is a useful fluorescence indicator for measuring NO activity in isolated hearts.

Life Sci 2007; 80:2076-84. [PMID: 17467744 DOI: 10.1016/j.lfs.2007.03.012] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2006] [Revised: 03/13/2007] [Accepted: 03/18/2007] [Indexed: 12/29/2022]
Abstract
Artificial anti-cell death protein FNK, a Bcl-x(L) derivative with three amino acid-substitutions (Y22F, Q26N, and R165K) has enhanced anti-apoptotic and anti-necrotic activity and facilitates cell survival in many species and cell types. The objectives of this study were (i) to investigate whether the protein conjugated with a protein transduction domain (PTD-FNK) reduces myocardial infarct size and improves post-ischemic cardiac function in ischemic/reperfused rat hearts, and (ii) to understand the mechanism(s) by which PTD-FNK exerts a protective effect. Isolated rat hearts were subjected to 35-min global ischemia, followed by 120-min reperfusion using the Langendorff methods. PTD-FNK (a total of 30 microl) was injected intramuscularly into the anterior wall of the left ventricle either at 1 min after induction of global ischemia (group A) or at 30 min after induction of global ischemia (at 5 min before reperfusion) (group B). In group A, infarct size was significantly reduced from 47.8+/-6.8% in the control to 30.4+/-5.2, 28.7+/-3.8, and 30.4+/-6.8% with PTD-FNK at 5, 50, and 500 nmol/l, respectively (p<0.05). Temporal recovery of left ventricular developed pressure at 60 min and 120 min after reperfusion was significantly better in PTD-FNK (50 and 500 nmol/l)-treated groups than in the control (p<0.05). In contrast, PTD-FNK treatment had no effect on group B. Western blot analysis showed that PTD-FNK markedly inhibited procaspase-3 cleavage (activation of caspase-3) and reduced the number of nuclei stained by a terminal deoxynucleotidyl transferase-mediated deoxyuridine 5-triphoshate nick-end labeling (TUNEL) assay. These findings suggest that PTD-FNK reduces the volume of myocardial infarction with corresponding functional recovery, at least in part, through the suppression of myocardial apoptosis following ischemia/reperfusion.

Abstract
This critical review discusses the results published between 2000 and 2005 on the development of analytical systems based on the luminol chemiluminescent and electrochemiluminescent reactions. An increasing number of non-specific detection systems based on the enhancing, inhibiting or catalysing effect of a large range of compounds have been published. Possible detected compounds and their concomitant presence in samples are discussed. Chemiluminescent and electrochemiluminescent reactions were also found to merge in biochip and microarray development as a possible substitute to the well-established but hardly quantitative fluorescent detections.

Abstract
Aim of this study was to investigate the cardiac release of nitric oxide (NO) before and after cold cardioplegia by a novel electron paramagnetic resonance (EPR) technique. Isolated rat hearts were perfused for 20 min in a Langendorff apparatus and then subjected to 3 hours potassium-hypotermic cardioplegia, followed by 20 min reperfusion. The coronary effluent was collected in a flask containing ferrous-bis-diethyldithiocarbamate as a spin trap of NO. Since the trapping agent was not delivered to the heart with the perfusion medium, we avoided that an abnormal extraction of NO from the tissue could inhibit its biological activity. The EPR signal was well detectable after equilibration (25.6 +/- 3.0 nmol/L +/- S.E.M.) and significantly increased following perfusion with 10 micromol/L serotonin (41.1 +/- 3.2 nmol/L) or 10 micromol/L nitroprusside (43.5 +/- 2.9 nmol/L). The basal level of NO did not change after reperfusion, but serotonin administration was not able to stimulate its release. Serotonin failure to stimulate NO production was not due to a loss of endothelial NO synthase, since its protein expression was not modified after reperfusion. The perfusion pressure increased by 51% after reperfusion and was quite completely restored following serotonin or nitroprusside treatment, with respect to the non-stimulated equilibration condition. Therefore, we suggest that the coronary spasm following a cold cardioplegic arrest is not due to an impaired production of basal NO and that NO-donors can be effective in relaxing vascular smooth muscle cells.
