Evaluation of In Vitro Immunomodulatory Activity of Withania somnifera Roots on Human Neutrophils.

The present study encompasses in vitro immunomodulatory activity of Withania somnifera WS (Solanaceae) examined on human neutrophils. The isolated compound of Withania somnifera roots was screened for its possible immunomodulatory activity by nitro blue tetrazolium test, phagocytosis of killed Candida albicans, neutrophil locomotion and chemotaxis. The extracted compound was examined at concentrations, viz.

Unicuspid unicommissural aortic valve: an extremely rare congenital anomaly.

Unicuspid aortic valve is a rare congenital malformation that usually presents in the 3rd to 5th decade of life-and usually with severe aortic stenosis or regurgitation. It often requires surgical correction. Diagnosis can be made with 2- or 3-dimensional transthoracic or transesophageal echocardiography, cardiac computed tomography, or cardiac magnetic resonance imaging.

Blockade of EMAP II protects cardiac function after chronic myocardial infarction by inducing angiogenesis.

Promoting angiogenesis is a key therapeutic target for protection from chronic ischemic cardiac injury. Endothelial-Monocyte-Activating-Polypeptide-II (EMAP II) protein, a tumor-derived cytokine having anti-angiogenic properties in cancer, is markedly elevated following myocardial ischemia. We examined whether neutralization of EMAP II induces angiogenesis and has beneficial effects on myocardial function and structure after chronic myocardial infarction (MI).

Hypertension in African Americans with heart failure: progression from hypertrophy to dilatation; perhaps not.

Aim: Concentric hypertrophy is thought to transition to left ventricular (LV) dilatation and systolic failure in the presence of long standing hypertension (HTN). Whether or not this transition routinely occurs in humans is unknown.

Methods: We consecutively enrolled African American patients hospitalized for acute decompensated volume overload heart failure (HF) in this retrospective study.

Aortic counterpulsation: C-pulse and other devices for cardiac support.

Heart failure is the leading cause of hospitalization in the USA. Despite major advances in the medical and device-related therapy including chronic resynchronization therapy for management of heart failure, significant number of patients eventually require advanced cardiac therapy including mechanical circulatory support or heart transplant. Heart transplant is a gold standard for end-stage heart failure but is limited by the donor heart shortage creating a definite need for alternative effective therapies.

Rapid Resolution of Acute Fulminant Myocarditis after IVIG and Steroid Treatment.

We report a case of a 59-year-old woman who presented with worsening dyspnea which rapidly progressed to severe heart failure. Coronary arteries showed no obstruction. Supportive measures stabilized the patient's hemodynamics.

Anteriorly displaced right coronary artery in acute myocardial infarction: what should every cardiologist know.

Anteriorly displaced right coronary artery (RCA) and anomalous origin RCAs occur in ≈ 1% and 0.1% of adult patients, respectively, and are the leading cause of incomplete coronary angiography and prolonged procedure times. We present a case in which anteriorly displaced RCA occlusion resulted in an acute inferior-posterior-right ventricular myocardial infarction complicated by complete atrioventricular block and hypotension.

An unusual combination of an anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and a right coronary artery system with two separate ostia from the aorta in an adult.

We describe a patient with an infrequent combination of variants in both the right and the left coronary arterial ostia, namely a combination of two separate right coronary artery (RCA) ostia from the aorta, and an anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA). To our knowledge, such a combination has not been previously reported. Based on published statistics for individual variants, such a combination is expected to occur approximately once for every 500,000 to one million live births.

Right coronary artery anatomical variants: where and how?

Background: Ectopic origin of the right coronary artery (RCA) occurs in approximately 1.0% of studied populations. We investigated the prevalence and location of ectopic RCAs among patients undergoing coronary angiography (CA) and assessed its effects on resource utilization.
