GPR 30 reduces myocardial infarct area and fibrosis in female ovariectomized mice by activating the PI3K/AKT pathway
Aims—Estrogen plays an important role in cardioprotection. Animal experiments showed that the G-protein coupled estrogen receptor 30 (GPR30) specific agonist G1 could reduce post-ischemic dysfunction and inhibit cardiac fibroblast proliferation. However, …

Portal milieu and the interplay of multiple anti-diabetic effects after gastric bypass surgery
AIMS: Diabetes is a worldwide health problem. Roux-en-Y-Gastric-Bypass (RYGB) leads to rapid resolution of Type-2-Diabetes (T2D). Decreased hepatic insulin resistance is key but underlying mechanisms are poorly understood. We hypothesized that changes in …

Time Series Characteristics of Serum Branched-Chain Amino Acids for Early Diagnosis of Chronic Heart Failure
Chronic heart failure (CHF) is an ongoing clinical syndrome with cardiac dysfunction that can be traced to alterations in cardiac metabolism. The identification of metabolic biomarkers in easily accessible fluids to improve the early diagnosis of CHF has …

Ablation of Cardiac TIGAR Preserves Myocardial Energetics and Cardiac Function in the Pressure Overload Heart Failure Model
Despite the advances in medical therapy, the morbidity and mortality of heart failure (HF) remain unacceptably high. HF results from reduced metabolism-contraction coupling efficiency, so the modulation of cardiac metabolism may be an effective strategy …

Sex influences susceptibility to methamphetamine cardiomyopathy in mice
In this study, we created a mouse model of methamphetamine cardiomyopa- thy that reproduces the chronic, progressive dosing commonly encountered in addicted subjects. We gradually increased the quantity of metham- phetamine given to C57Bl/6 mice from 5 to …

Rapamycin attenuates a murine model of thoracic aortic aneurysm by downregulating the miR-126–3p mediated activation of MAPK/ERK signalling pathway
Thoracic aortic aneurysm (TAA) is fatal diseases, which leads to aortic rupture and sudden death. Blood pressure-lowering drugs are ineffective for most of the patients. Our previous study demonstrated the inhibition of endothelial secreted miR-126e3p by …

A Net Mold-based Method of Scaffold-free Three-Dimensional Cardiac Tissue Creation
This protocol describes a novel and easy net mold-based method to create three-dimensional (3-D) cardiac tissues without additional scaffold material. Human-induced pluripotent stem-cell-derived cardiomyocytes (iPSC-CMs), human cardiac fibroblasts (HCFs), …

Prior β-blocker treatment decreases leukocyte responsiveness to injury
Following injury, leukocytes are released from hematopoietic organs and migrate to the site of damage to regulate tissue inflammation and repair, however leukocytes lacking β2-adrenergic receptor (β2AR) expression have marked impairments in these …

Solid stress in brain tumours causes neuronal loss and neurological dysfunction and can be reversed by lithium
The compression of brain tissue by a tumour mass is believed to be a major cause of the clinical symptoms seen in patients with brain cancer. However, the biological consequences of these physical stresses on brain tissue are unknown. Here, via imaging …

Short-Term Preoperative Protein Restriction Attenuates Vein Graft Disease via Induction of Cystathionine ϒ-Lyase
AIMS: Therapies to prevent vein graft disease, a major problem in cardiovascular and lower extremity bypass surgeries, are currently lacking. Short-term preoperative protein restriction holds promise as an effective preconditioning method against surgical …
