Catecholamines induce metamorphosis in the hydrozoan Halocordyle disticha but not in Hydractinia echinata.

Roux's archives of developmental biology : the official organ of the EDBO

Edwards NC, Thomas MB, Long BA, Amyotte SJ.
PMID: 28305639
Rouxs Arch Dev Biol. 1987 Sep;196(6):381-384. doi: 10.1007/BF00375776.

Planula larvae of the marine hydroids Halocordyle disticha and Hydractinia echinata were treated with the catecholamines epinephrine, norepinephrine and dopamine, as well as with certain of their precursors and agonists. Norepinephrine, L-dopa, dopamine and the dopamine agonist ADTN at...

Beta-Blockers and Oxidative Stress in Patients with Heart Failure.

Pharmaceuticals (Basel, Switzerland)

Nakamura K, Murakami M, Miura D, Yunoki K, Enko K, Tanaka M, Saito Y, Nishii N, Miyoshi T, Yoshida M, Oe H, Toh N, Nagase S, Kohno K, Morita H, Matsubara H, Kusano KF, Ohe T, Ito H.
PMID: 26791643
Pharmaceuticals (Basel). 2011 Aug 05;4(8):1088-100. doi: 10.3390/ph4081088.

Oxidative stress has been implicated in the pathogenesis of heart failure. Reactive oxygen species (ROS) are produced in the failing myocardium, and ROS cause hypertrophy, apoptosis/cell death and intracellular Ca(2+) overload in cardiac myocytes. ROS also cause damage to...

The effect of meditation on regulation of internal body states.

Frontiers in psychology

Khalsa SS, Rudrauf D, Davidson RJ, Tranel D.
PMID: 26217263
Front Psychol. 2015 Jul 07;6:924. doi: 10.3389/fpsyg.2015.00924. eCollection 2015.

Meditation is commonly thought to induce physiologically quiescent states, as evidenced by decreased autonomic parameters during the meditation practice including reduced heart rate, respiratory rate, blood pressure, skin conductance, and increased alpha activity in the electroencephalogram. Preliminary empirical support...

Cardioprotective Effects of Essential Oil of Lavandula angustifolia on Isoproterenol-induced Acute Myocardial Infarction in Rat.

Iranian journal of pharmaceutical research : IJPR

Ziaee M, Khorrami A, Ebrahimi M, Nourafcan H, Amiraslanzadeh M, Rameshrad M, Garjani M, Garjani A.
PMID: 25561934
Iran J Pharm Res. 2015;14(1):279-89.

Myocardial infarction (MI) is a common presentation of the ischemic heart disease. Lavandula angustifolia is an herbaceous plant with antioxidative effects. This study was designed to investigate the cardioprotective effects of lavandula angustifolia essential oil against isoproterenol-induced MI in...

Neuroglobin protects cardiomyocytes against apoptosis and cardiac hypertrophy induced by isoproterenol in rats.

International journal of clinical and experimental medicine

Liu ZF, Zhang X, Qiao YX, Xu WQ, Ma CT, Gu HL, Zhou XM, Shi L, Cui CX, Xia D, Chen YG.
PMID: 26131111
Int J Clin Exp Med. 2015 Apr 15;8(4):5351-60. eCollection 2015.

Neuroglobin (Ngb) is well known as a physiological role in oxygen homeostasis of neurons and perhaps a protective role against hypoxia and oxidative stress. In this study, we found that Ngb is expressed in rat heart tissues and it...

Swallowing-induced atrial tachyarrhythmias successfully ablated at the left posterior interatrial septum in patient with wolff-Parkinson-white syndrome.

Korean circulation journal

Ban JE, Park SW, Lee HS, Choi JI, Kim YH.
PMID: 26023316
Korean Circ J. 2015 May;45(3):253-8. doi: 10.4070/kcj.2015.45.3.253. Epub 2015 May 27.

We reported a case of a 55-year-old patient who presented with palpitation after swallowing. Initial surface electrocardiogram revealed ventricular preexcitation utilizing a left lateral bypass tract. The orthodromic atrioventricular reentrant tachycardia (AVRT) was induced during electrophysiologic studies. After successful...

Effect of Isoproterenol on LDL Susceptibility to Oxidation and Serum Total Antioxidant Capacity in Cyclosporine-Treated Rats.

International journal of organ transplantation medicine

Foroughimoghaddam H, Ghorbanihaghjo A, Rashtchizadeh N, Argani H.
PMID: 25013580
Int J Organ Transplant Med. 2010;1(3):139-45.

BACKGROUND: Cyclosporine therapy is associated with a variety of adverse effects. Recent studies have suggested increased oxidative stress as a cause of these side effects.OBJECTIVE: Since, melatonin is one of the most powerful known antioxidants, and considering that isoproterenol...

Avicenna journal of phytomedicine

Srivastav RK, Siddiqui HH, Mahmood T, Ahsan F.
PMID: 25050277
Avicenna J Phytomed. 2013;3(3):216-23.

OBJECTIVE: The study was conducted to evaluate cardioprotective effect of silk cocoon (Abresham) Bombyx mori (B. mori) on isoprenaline-induced myocardial infarction. This study deals with the cocoons, which is called Abresham in the Unani system of medicine. It is...

Endothelin-evoked Release of Arachidonic Acid from Mouse Astrocytes in Primary Culture.

The European journal of neuroscience

Tencé M, Cordier J, Glowinski J, Prémont J.
PMID: 12106434
Eur J Neurosci. 1992;4(10):993-999. doi: 10.1111/j.1460-9568.1992.tb00125.x.

In striatal astrocytes, receptors for the vasoactive peptide endothelin (ET) are associated with several intracellular signalling pathways: ET-1 increases the breakdown of phosphoinositides, induces a sustained influx of Ca2+ and inhibits the isoproterenol-induced formation of cAMP (Marin et al.,...

Dietary fish oil prevents asynchronous contractility and alters Ca(2+) handling in adult rat cardiomyocytes.

The Journal of nutritional biochemistry

Leifert WR, Dorian CL, Jahangiri A, McMurchie EJ.

This study examined the effects of dietary incorporation of n-3 polyunsaturated fatty acids (PUFAs) into cardiac membrane phospholipids on Ca(2+) handling (using Fura-2) and arrhythmic contractility in electrically-stimulated, adult rat ventricular cardiomyocytes. Dietary lipid supplementation with fish oil (FO)...

Enzyme-catalyzed processes of first-pass hepatic and intestinal drug extraction.

Advanced drug delivery reviews
