Beneficial actions of EGb 761 against ischemia/reperfusion (I/R) injury in lung, brain and renal ischemia have been described. However, the relationship between EGb 761 and signal molecules in myocardial ischemia reperfusion has not been well elucidated. In this study, we investigated the effects and mechanism of EGb 761 preconditioning on anti-myocardial I/R injuries in vivo. Meanwhile, their potential anti-oxidative stress and anti-inflammation effect were assessed. Hemodynamic parameters were monitored as left ventricular systolic pressure, LV end-diastolic pressure and maximal rate of increase and decrease of left ventricular pressure (dP/dtmax)...

INTRODUCTION: Advances in organ allocation, surgical technique, immunosuppression, and long-term follow-up have led to a significant improvement in kidney transplant outcomes. Although there are clear recommendations for several aspects of kidney transplant management, there are no pediatric-specific guidelines for immediate postoperative care. The aim of this survey is to examine practice variations in the immediate postoperative care of pediatric kidney transplant patients. METHODS: We surveyed medical directors of Pediatric Acute Lung Injury and Sepsis Investigators (PALISI)-affiliated pediatric intensive care units regarding center-specific immediate postoperative management of pediatric kidney transplantation...

The temporary total artificial heart (TAH-t) has been valuable as a bridge to transplantation in patients with biventricular failure. However, the challenges of accurately assessing pulmonary vascular resistance after TAH-t implantation can preclude these patients from heart transplantation, especially those with pre-existing pulmonary hypertension. The CardioMEMS Heart Failure System (St. Jude's Medical, Little Canada, MN) comprises a wireless pressure sensor that is implanted percutaneously in the pulmonary artery and transmits real-time measurements of pulmonary artery pressures...

Hypertension is a well-documented predictive factor for cardiovascular events. Clinical studies have extensively demonstrated the differential hemodynamic consequences of various anti-hypertensive drugs, but failed to clearly elucidate the underlying mechanisms due to the difficulty in performing a quantitative deterministic analysis based on clinical data that carry confounding information stemming from inter-patient differences and the nonlinearity of cardiovascular hemodynamics. In the present study, a multi-scale model of the cardiovascular system was developed to quantitatively investigate the relationships between hemodynamic variables and cardiovascular properties under hypertensive conditions, aiming to establish a theoretical basis for assisting in the interpretation of clinical observations or optimization of therapy...

Adults with psychopathy have a high propensity for substance abuse, generally starting from a young age. This investigation tested hypotheses about differences in the neural responses associated with drug craving among high-risk young offenders with histories of abuse of stimulants and other drugs as a function of psychopathic traits. Fifty-four male adolescents (44 with a history of stimulant abuse and 10 controls) incarcerated at a maximum-security facility (M age = 17.08 years) completed a drug-cue exposure task while brain hemodynamic activity was monitored using functional magnetic resonance imaging (fMRI) with a mobile MRI scanner stationed at the facility...

PURPOSE: Current analgesic strategies for propofol injection pain may cause adverse reactions during electroconvulsive therapy (ECT), such as shortening seizure duration. This study investigated whether dexmedetomidine could attenuate propofol injection pain in ECT. METHODS: Participants were randomly allocated to receive 0.2 μg/kg dexmedetomidine (Dex-0.2 group), 0.5 μg/kg dexmedetomidine (Dex-0.5 group) or saline (control group) prior to ECT. The composite pain scale and objective Surgical Pleth Index (SPI) were used to measure the intensity of injection pain, and the percentage of patients with pain score > 2 was the primary outcome...

Zinc is an essential micronutrient in pregnancy and zinc deficiency impairs fetal growth. We used a mouse model of moderate zinc deficiency to investigate the physiological mechanisms by which zinc is important to placental morphogenesis and the maternal blood pressure changes during pregnancy. A 26% reduction in circulating zinc (P = 0.005) was exhibited in mice fed a moderately zinc-deficient diet. Zinc deficiency in pregnancy resulted in an 8% reduction in both near term fetal and placental weights (both P < 0...

Sepsis and acute kidney injury (AKI) synergistically increase morbidity and mortality in the ICU. How sepsis reduces GFR and causes AKI is poorly understood; one proposed mechanism includes tubuloglomerular feedback (TGF). When sodium reabsorption by the proximal tubules is reduced in normal animals, the macula densa senses increased luminal sodium chloride, then adenosine 1a receptor (A1aR) signaling triggers tubuloglomerular feedback, reducing GFR through afferent arteriole vasoconstriction. We measured GFR and systemic hemodynamics early during cecal ligation and puncture-induced sepsis in wild-type and A1aR knockout mice...

BACKGROUND: The lower limb muscle may play an important role in decreasing the heart's pumping workload. Aging and inactivity cause atrophy and weakness of the muscle, leading to a loss of the heart-assisting role. An electrical lower limb muscle stimulator can prevent atrophy and weakness more effectively than conventional resistance training; however, it has been reported to increase the heart's pumping workload in some situations. Therefore, more effective tools should be developed...

Cardiogenic shock (CS) is a state of critical end-organ hypoperfusion due to reduced cardiac output, despite adequate filling status. The development of multiorgan dysfunction is believed to be the major contributor to the high early mortality. Little evidence exists as to which vasopressor or inotrope should best be used for early treatment; however, customized pharmacological therapy, tailored on hemodynamic monitoring, is essential to achieve normal peripheral perfusion. Moreover, an increasing number of mechanical circulatory support devices are available for hemodynamic support in patients with CS but, at present, data derived from randomized clinical trials on the effectiveness, safety, differential indications for mechanical support devices, and optimal implant timing are limited...

Cardiogenic shock (CS) is a life-threatening condition that occurs in response to reduced cardiac output, in the presence of adequate intravascular volume, and results in tissue hypoxia. CS can occur as a result of several etiologies but the most common is acute myocardial infarction. Despite the introduction of emergency revascularization for CS complicating acute myocardial infarction, mortality still remains exceptionally high, particularly in patients with refractory CS. The diagnosis of CS is sometimes challenging and it is based on clinical, hemodynamic, and biochemical signs...
