PMID: 24241614
Planta. 1985 Dec;166(4):490-9. doi: 10.1007/BF00391273.

The dependence of the membrane potential of Eremosphaera viridis on different external concentrations of potassium, sodium, calcium, and protons was compared with the diffusion potential measured in the dark and in the presence of NaN3. In contrast to some...

The depressor response to intracerebroventricular hypotonic saline is sensitive to TRPV4 antagonist RN1734.

Frontiers in pharmacology

Feetham CH, Nunn N, Barrett-Jolley R.
PMID: 25954200
Front Pharmacol. 2015 Apr 23;6:83. doi: 10.3389/fphar.2015.00083. eCollection 2015.

Several reports have shown that the periventricular region of the brain, including the paraventricular nucleus (PVN), is critical to sensing and responding to changes in plasma osmolality. Further studies also implicate the transient receptor potential ion channel, type V4...

Vasogenic shock physiology.

Open access emergency medicine : OAEM

Gkisioti S, Mentzelopoulos SD.
PMID: 27147845
Open Access Emerg Med. 2011 Jan 06;3:1-6. doi: 10.2147/OAEM.S10388. eCollection 2011.

Shock means inadequate tissue perfusion by oxygen-carrying blood. In vasogenic shock, this circulatory failure results from vasodilation and/or vasoplegia. There is vascular hyporeactivity with reduced vascular smooth muscle contraction in response to α1 adrenergic agonists. Considering vasogenic shock, one...

Update on the implication of potassium channels in autism: K(+) channelautism spectrum disorder.

Frontiers in cellular neuroscience

Guglielmi L, Servettini I, Caramia M, Catacuzzeno L, Franciolini F, D'Adamo MC, Pessia M.

OBJECTIVES: The effect of agmatine on prostate contractility as well as the roles of imidazoline receptors and potassium channels in this action were studied using isolated Wistar rat prostate tissue.METHODS: Rat prostate strips were pre-contracted with 1 µmol/L phenylephrine...

The Effect of Glibornuride on Plasma Atrial Natriuretic Factor Levels in Patients with Newly Diagnosed NIDDM.

Endocrine regulations

Cakir B, Ayavaz G, Cakir N, Arslan M.
PMID: 10407367
Endocr Regul. 1998 Mar;32(1):27-31.

The aim of this clinical trial was to study the participation of plasma atrial natriuretic factor (ANF) in the risk of developing diabetic nephropathy by increasing the intraglomerular pressure. The effect of glibornuride on the plasma ANF levels and...

Auxiliary subunits of Shaker-type potassium channels.

Trends in cardiovascular medicine

Xu J, Li M.
PMID: 14987569

Voltage-gated potassium channels are important determinants of membrane excitability. This family of ion channels is composed of several classes of proteins, including the pore-forming Kvalpha subunits and the recently identified auxiliary Kvbeta subunits. A combination of a large number...

Electrogenic transport properties of growing Arabidopsis root hairs : the plasma membrane proton pump and potassium channels.

Plant physiology
