Pharmacokinetic characteristics of hydroxysafflor yellow A in normal and diabetic cardiomyopathy mice
Hydroxysafflor yellow A (HSYA), a major active water-soluble component in Carthamus tinctorius L., is considered a potential antioxidant with protective effects against myocardial injury. However, its pharmacokinetic characteristics in normal and diabetic …

Low Dose of Folic Acid Can Ameliorate Hyperhomocysteinemia-Induced Cardiac Fibrosis and Diastolic Dysfunction in Spontaneously Hypertensive Rats
To evaluate whether lowering plasma homocysteine (Hcy) levels at different doses of folic acid (FA) could reduce cardiac fibrosis and diastolic dysfunction in spontaneously hypertensive rats (SHRs) with hyperhomocys-teinemia (Hhcy) and investigate the …

Extracellular vesicles derived from myocardial infarction plasma inhibit BMSCs apoptosis and enhance cardiac function via AKT signaling pathway
This study aimed to investigate whether extracellular vesicles (EVs) secreted in myocardial infarction (MI) plasma could protect against apoptosis of bone marrow mesenchymal stem cells (BMSCs) following hypoxia or serum deprivation in vitro and improve …

The effect of targeting Tie2 on hemorrhagic shock-induced renal perfusion disturbances in rats
BACKGROUND: Hemorrhagic shock is associated with acute kidney injury and increased mortality. Targeting the endothelial angiopoietin/Tie2 system, which regulates endothelial permeability, previously reduced hemorrhagic shock-induced vascular leakage. We …

The insulin receptor family and protein kinase B (Akt) are activated in the heart by alkaline pH and α1-adrenergic receptors
Insulin and insulin-like growth factor stimulate protein synthesis and cardioprotection in the heart, acting through their receptors (INSRs, IGF1Rs) and signalling via protein kinase B (PKB, also known as Akt). Protein synthesis is increased in hearts …

Donor Myocardial Infarction Impairs the Therapeutic Potential of Bone Marrow Cells by an Interleukin-1-Mediated Inflammatory Response
Delivery of bone marrow cells (BMCs) to the heart has substantially improved cardiac function in most rodent models of myocardial infarction (MI), but clinical trials of BMC therapy have led to only modest improvements. Rodent models typically involve …

Magnetic black phosphorus microbubbles for targeted tumor theranostics
Black phosphorus (BP) is attracting more and more interest for the biomedical application. The absorption in a wide spectral range and high photothermal conversion efficiency make BP suitable for photothermal therapy. However, BP alone is hard to realize …

Chronic stimulation of group II metabotropic glutamate receptors in the medulla oblongata attenuates hypertension development in spontaneously hypertensive rats
Baroreflex dysfunction is partly implicated in hypertension and one responsible region is the dorsal medulla oblongata including the nucleus tractus solitarius (NTS). NTS neurons receive and project glutamatergic inputs to subsequently regulate blood …

Cardiac metallothionein overexpression rescues diabetic cardiomyopathy in Akt2-knockout mice
To efficiently prevent diabetic cardiomyopathy (DCM), we have explored and confirmed that metallothionein (MT) prevents DCM by attenuating oxidative stress, and increasing expression of proteins associated with glucose metabolism. To determine whether …

8-Formylophiopogonanone B antagonizes doxorubicin-induced cardiotoxicity by suppressing heme oxygenase-1-dependent myocardial inflammation and fibrosis
Doxorubicin (DOX) is a widely used antitumor drug that causes severe cardiotoxicity in patients; no effective strategy yet exists to address this problem. We previously reported that 8-formylophiopogonanone B (8-FOB), a natural isoflavone in Ophiopogon …
