Past experiments show that echolocating bats of the species Myotis lucifugus and Eptesicus fuscus can discriminate among airborne sonar targets presented in the context of pursuit maneuvers for the interception of prey. These bats distinguish between edible mealworms and inedible spheres of various sizes. Myotis can distinguish between disks and mealworms(More)
The ability of the echolocating bat, Eptesicus fuscus, to detect a sonar target is affected by the presence of other targets along the same axis at slightly different ranges. If echoes from one target arrive at about the same delay as echoes from another target, clutter interference occurs and one set of echoes masks the other. Although the bat's sonar(More)
BACKGROUND Diabetic cardiomyopathy, a diabetes-specific complication, refers to a disorder that eventually leads to left ventricular hypertrophy in addition to diastolic and systolic dysfunction. In recent studies, hyperglycemia-induced reactive oxygen species (ROS) in cardiomyocytes have been linked to diabetic cardiomyopathy. GATA binding protein 4(More)
ETHNOPHARMACOLOGICAL RELEVANCE Rhodiola rosea (also known as golden root or roseroot) is a perennial plant of the Crassulaceae family that grows in the Arctic and in the mountainous regions of Europe, Asia, and North America. The rhizome and roots of this plant have been long used as traditional medicine in Eastern Europe and Asia for enhancing physical and(More)
We study the width-amplitude relation for three-dimensional Bernstein-Greene-Kruskal (BGK) electrostatic solitary waves in magnetized plasmas, taking into account the dynamics of both electrons and ions. We obtain two coupled inequalities that constrain the amplitude and the widths parallel and perpendicular to the magnetic field for a Gaussian potential,(More)
Sphingomyelinase (SMase) regulates an activation of the sphingomyelin cycle. Recent studies have shown that it is a novel modulator of monoamine receptor and transporter functions; however, its mechanisms are not fully understood. Our previous studies have found that interferon-alpha (IFN-α) up-regulates serotonin (5-HT) transporter expression and induces(More)
BACKGROUND AND PURPOSE Digoxin has been used as an inotropic agent in heart failure for a long time. Troponin I (TnI) phosphorylation is related to cardiac contractility, and the genes are regulated by peroxisome proliferator-activated receptors (PPARs). Our previous studies indicated that cardiac abnormality related to the depressed expression of PPARδ in(More)
It has been indicated that activation of peripheral imidazoline I2-receptor (I-2R) may reduce the blood pressure in spontaneously hypertensive rats (SHRs). Also, guanidinium derivatives show the ability to activate imidazoline receptors. Thus, it is of special interest to characterize the I-2R using guanidinium derivatives in blood vessels for development(More)
The contact pressure experienced by human vocal folds during phonation is usually considered as the most likely source of phonotrauma. Direct contact pressure measurements using pressure sensors were attempted, although some interference with vocal folds oscillation was found to occur. A nonintrusive approach for the contact pressure estimation from high(More)
BACKGROUND Rhodiola rosea (Rhodiola) is a plant in the Crassulaceae family that grows in cold regions of the world. It is mainly used in clinics as an adaptogen. Recently, it has been mentioned that Rhodiola increases plasma β-endorphin to lower blood pressure. Thus, the present study aims to investigate the antidiabetic action of Rhodiola in relation to(More)
