Stimulation of cardiac sympathetic afferents evokes excitatory cardiovascular reflexes. However, the exact regions in the brain that integrate these reflexes have not been identified. Expression of c-Fos in the neurons provides a useful marker of the activated neurons. In the present study, we examined the response of c-Fos within the medulla of the cat to(More)
AIMS The objective of this study was to investigate whether a cytoprotective herb-derived agent, Ginkgo biloba extract (EGb) 761, could have a beneficial effect on doxorubicin-induced cardiac toxicity in vitro and in vivo. METHODS AND RESULTS Primary cultured neonatal rat cardiomyocytes were treated with the vehicle, doxorubicin (1 microM), EGb761 (25(More)
Insulin-like growth factor-1 (IGF 1) suppresses myocardial apoptosis and improves myocardial function in experimental models of cardiomyopathy. Apoptosis is triggered by mitochondria dysfunction and subsequent activation of caspases. We had previously shown that IGF 1 inhibited cardiomyocyte apoptosis via suppression of caspase, however, how IGF 1 and its(More)
Insulin deficiency downregulates HSP60 and IGF-I receptor signaling and disrupts intracellular signaling homeostasis in diabetic cardiac muscle. Our previous studies had shown that IGF-I receptor signaling can be modulated by the abundance of HSP60. Since HSP60 localizes to the cytoplasmic compartment and mitochondria, this study was carried out to(More)
BACKGROUND Whether serum triglyceride level correlates with clinical outcomes of patients with ST segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (pPCI) remains unclear. METHODS From June 2008 to February 2012, all patients with STEMI who were treated with pPCI in this tertiary referral hospital and(More)
Shikonin, a natural naphthoquinone pigment isolated from Lithospermum erythrorhizon, has been reported to suppress growth of various cancer cells. This study was aimed to investigate whether this chemical could also inhibit cell growth of lung cancer cells and, if so, works via what molecular mechanism. To fulfill this, A549 lung cancer cells were treated(More)
We investigated the association between the risk of herpes zoster (HZ) and diabetes-related macrovascular comorbidities and microvascular disorders in diabetic patients. This retrospective study included 25,345 patients with newly identified HZ and age- and gender-matched controls retrieved from the National Health Insurance Research Database in Taiwan(More)
