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...

Influence of Diet and Dehydroepiandrosterone on Hypothalamic Monoamine Neurotransmitters in Zucker Rats.

Nutritional neuroscience

Svec F, Porter J.
PMID: 27415806
Nutr Neurosci. 1999;2(5):337-45. doi: 10.1080/1028415X.1999.11747288.

Food intake is controlled by hypothalamic neurotransmitters. Exogenous dehydroepiandrosterone (DHEA) decreases Zucker rat caloric intake, alters selection of macronutrients and affects the level of hypothalamic neurotransmitters. The goal of this study was to determine whether the changes induced by...

Oesophageal Pain and Catecholamine Mediated Ecg Changes Mimicking Myocardial Ischaemia.

Bristol medico-chirurgical journal (1963)

Logan RF, Shahi J, Sanderson JE.
PMID: 28906751
Bristol Med Chir J. 1987 May;102(2):41-50.

It is known that oesophageal pain can imitate angina and also that non specific ECG changes, probably catecholamine mediated, can be similar to those due to true myocardial ischaemia. Both of these can therefore pose a problem for the...

Dopaminergic Input to the Inferior Colliculus in Mice.

Frontiers in neuroanatomy

Nevue AA, Elde CJ, Perkel DJ, Portfors CV.
PMID: 26834578
Front Neuroanat. 2016 Jan 21;9:168. doi: 10.3389/fnana.2015.00168. eCollection 2015.

The response of sensory neurons to stimuli can be modulated by a variety of factors including attention, emotion, behavioral context, and disorders involving neuromodulatory systems. For example, patients with Parkinson's disease (PD) have disordered speech processing, suggesting that dopamine...

Complete Remission in Metastatic Pheochromocytoma Treated with Extensive Surgery.

Cureus

Arnas-Leon C, Sánchez V, Santana Suárez AD, Quintana Arroyo S, Acosta C, Martinez Martin FJ.
PMID: 26918215
Cureus. 2016 Jan 05;8(1):e447. doi: 10.7759/cureus.447.

Pheochromocytomas are rare neuroendocrine tumors that arise from chromaffin cells of the adrenal medulla. Malignant pheochromocytoma is defined as the presence of metastatic spread in tissues where chromaffin cells are not usually present. This case report describes the case...

Effects of Mind-Body Training on Cytokines and Their Interactions with Catecholamines.

Psychiatry investigation

Jang JH, Park HY, Lee US, Lee KJ, Kang DH.
PMID: 28845176
Psychiatry Investig. 2017 Jul;14(4):483-490. doi: 10.4306/pi.2017.14.4.483. Epub 2017 Jul 11.

OBJECTIVE: Mind-body training (MBT) may control reactions to stress and regulate the nervous and immune systems. The present study was designed to assess the effects of MBT on plasma cytokines and their interactions with catecholamines.METHODS: The study group consisted...

Whether it's a study on endorphins, catecholamines, altitude sickness, or thermal injury, John R. Sutton, MD, is sure to be in the thick of the research, quickly disseminating what he's learned, while applying the principles to himself. Teacher, researcher,...

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...

Acute oral administration of low doses of methylphenidate targets calretinin neurons in the rat septal area.

Frontiers in neuroanatomy

García-Avilés Á, Albert-Gascó H, Arnal-Vicente I, Elhajj E, Sanjuan-Arias J, Sanchez-Perez AM, Olucha-Bordonau F.
PMID: 25852493
Front Neuroanat. 2015 Mar 23;9:33. doi: 10.3389/fnana.2015.00033. eCollection 2015.

Methylphenidate (MPD) is a commonly administered drug to treat children suffering from attention deficit hyperactivity disorder (ADHD). Alterations in septal driven hippocampal theta rhythm may underlie attention deficits observed in these patients. Amongst others, the septo-hippocampal connections have long...

Effect of Magnesium Sulfate and Clonidine in Attenuating Hemodynamic Response to Pneumoperitoneum in Laparoscopic Cholecystectomy.

Anesthesia, essays and researches

Kamble SP, Bevinaguddaiah Y, Nagaraja DC, Pujar VS, Anandaswamy TC.
PMID: 28298759
Anesth Essays Res. 2017 Jan-Mar;11(1):67-71. doi: 10.4103/0259-1162.200228.

BACKGROUND: Pneumoperitoneum in laparoscopic procedures is associated with hemodynamic response, due to the release of catecholamines and vasopressin. Magnesium and clonidine have been used to attenuate such hemodynamic responses by inhibiting release of these mediators. We conducted this randomized,...
