Polyaniline (PANi), a conductive polymer, was blended with a natural protein, gelatin, and co-electrospun into nanofibers to investigate the potential application of such a blend as conductive scaffold for tissue engineering purposes. Electrospun PANi-contained gelatin fibers were characterized using scanning electron microscopy (SEM), electrical conductivity measurement, mechanical tensile tes...

Myoblast transplant for cardiac repair offers an alternative therapeutic modality for cardiac repair. This novel cell based approach has the potential for replacing cardiomyocytes damaged during the disease process. Studies in the small and large animals and human phase-I trials have shown that myoblast transplantation into damaged myocardium results in the improved myocardial function and hemo...

Sodium nitroprusside (SNP) releases nitric oxide (NO), a powerful vasodilator, and thus widely used in intensive care unit for treating hypertension emergency. However, cardiac toxicity after SNP administration is a clinical problem. For finding a natural compound that suppressing SNP-induced cardiac toxicity, we tested the protective potential of kobophenol A (Kob A), purified from the root of...

Objective(s) Doxorubicin (DOX), a widely used chemotherapeutic agent can give rise to serve cardiotoxicity by inducing apoptosis. Curcumin, the active compound of the rhizome of Curcuma longa L. has anti-inflammatory, antioxidant and anti-proliferative activities. Curcumin has been identified to increase cytotoxicity in several cancer cell lines in combination with DOX, but there is no study a...

AIMS Transplantation of myoblast sheets is a promising therapy for enhancing cardiac function after heart failure. We have previously demonstrated that a 7-amino-acid sequence (Ser-Val-Val-Tyr-Gly-Leu-Arg) derived from osteopontin (SV peptide) induces angiogenesis. In this study, we evaluated the long-term therapeutic effects of myoblast sheets secreting SV in a rat infarction model. METHODS ...

Hydrogen sulphide (H2S), a newly identified gasotransmitter, can be endogenously produced by cystathionine gamma-lyase (CSE) in the cardiovascular system. This study investigated role of CSE/H2S system on lipid overload-induced lipotoxicity and cardiac senescence. Lipid overload rat cardiomyocyte cells (H9C2) promoted intracellular accumulation lipid, oxidative stress, mitochondrial dysfunction...

objective(s) doxorubicin (dox), a widely used chemotherapeutic agent can give rise to serve cardiotoxicity by inducing apoptosis. curcumin, the active compound of the rhizome of curcuma longa l. has anti-inflammatory, antioxidant and anti-proliferative activities. curcumin has been identified to increase cytotoxicity in several cancer cell lines in combination with dox, but there is no study ab...

Doxorubicin (DOX) is a potent and currently available antitumor therapeutic agent; however, its clinical application is limited by the occurrence of cardiotoxicity. Preliminary evidence indicates that hydrogen sulfide (H2S) may exert protective effects against DOX cardiotoxicity. Therefore, the aim of the present study was to investigate whether calreticulin (CRT) is involved in the cardioprote...

The calcium/calmodulin-dependent phosphatase calcineurin has been shown to be both necessary and sufficient to induce cardiac hypertrophy in vivo and in vitro. Treatment with the antineoplastic agent doxorubicin (DOX) was shown to activate calcineurin signaling in H9c2 rat cardiac muscle cells; however, the effect of this activation on hypertrophy was not investigated. Therefore, the present st...
