AIMS: Adiponectin, an adipocyte-specific secretory protein, abundantly exists in the blood stream while its concentration paradoxically decreases in obesity. Hypoadiponectinemia is one of risks of cardiovascular diseases. However, impact of serum adiponectin concentration on acute ischemic myocardial damages has not been fully clarified. The present study investigated the association of serum adiponectin and creatine kinase (CK)-MB levels in subjects with ST-segment elevation myocardial infarction (STEMI)...

The cardiotoxicity of arsenic trioxide (ATO) limits its clinical application in cancer treatment. Evidences suggest that sorbus has antioxidant activity and its consumption has been linked with improved cardioprotection. In this study, we investigated the cardio-protective effect and mechanisms of Sorbus pohuashanensis (Hante) Hedl. flavonoids (SPF) against ATO in BALB/c mice and H9c2 cells. Eleven major flavonoids were confirmed by ultra-performance liquid chromatography electrospray ionization quadrupole time of flight mass spectrometry (UPLC-ESI-Q-TOF-MS)...

Effect of Tramadol infusion (5 mg/ml) on oxytocin-induced uterine contractile activity was studied in chronic experiment on female rabbits with different degrees of biological readiness for parturition. In case of sufficient biological readiness for parturition, Tramadol did not change the number of uterine contractions, but increased the amplitude and duration of each contraction against the background of increased creatine phosphate consumption by the myometrium. At the same time, Tramadol infusion to females without biological readiness for partirition suppressed induced uterine contractile activity by reducing the amplitude of each uterine contraction...

Penehyclidine hydrochloride (PHC) is an anticholinergic drug that has been widely used in the clinic for years, evaluating for anesthetic premedication, anti-muscarinic, or improving microcirculation. However, very little is known about its protective effects against anoxia/reoxygenation (A/R) injury in myocardiocytes. The aim of our study was to investigate the protective effects of PHC pretreatment on A/R injury, as well as the underlying mechanisms involved. To investigate apoptosis, we used the cell viability assay, Annexin-V/PI assay, and lactate dehydrogenase (LDH) and creatine kinase (CK) activity measurements...

BACKGROUND: Detectable levels of high sensitivity (cardiac) troponin T (HsTnT), occur in the majority of patients with stable coronary heart disease (CHD), and often in 'healthy' individuals. Extreme physical activity may lead to marked elevations in creatine kinase MB and TnT levels. However, whether HsTnT elevations occur commonly after exercise stress testing (EST), and if so, whether this has clinical significance, needs clarification. METHODS: To determine whether HsTnT levels become elevated after EST (Bruce protocol) to ≥95% of predicted maximum heart rate in presumed healthy subjects without overt CHD, we assayed HsTnT levels for ∼5h post-EST in 105 subjects (median age 37 years)...

BACKGROUND: Magnetic resonance spectroscopy (MRS) provides non-invasive information about the metabolic pattern of the brain parenchyma in vivo. The SpectraClassifier software performs MRS pattern-recognition by determining the spectral features (metabolites) which can be used objectively to classify spectra. Our aim was to develop an Infarct Evolution Classifier and a Brain Regions Classifier in a rat model of focal ischemic stroke using SpectraClassifier. RESULTS: A total of 164 single-voxel proton spectra obtained with a 7 Tesla magnet at an echo time of 12 ms from non-infarcted parenchyma, subventricular zones and infarcted parenchyma were analyzed with SpectraClassifier ( http://gabrmn...
