Effect of lysophosphatidic acid on the immune inflammatory response and the connexin 43 protein in myocardial infarction.

Experimental and therapeutic medicine

Zhang D, Zhang Y, Zhao C, Zhang W, Shao G, Zhang H.
PMID: 27168781
Exp Ther Med. 2016 May;11(5):1617-1624. doi: 10.3892/etm.2016.3132. Epub 2016 Mar 09.

Lysophosphatidic acid (LPA) is an intermediate product of membrane phospholipid metabolism. Recently, LPA has gained attention for its involvement in the pathological processes of certain cardiovascular diseases. The aim of the present study was to clarify the association between...

Volatile anesthetics suppress glucose-stimulated insulin secretion in MIN6 cells by inhibiting glucose-induced activation of hypoxia-inducible factor 1.

PeerJ

Suzuki K, Sato Y, Kai S, Nishi K, Adachi T, Matsuo Y, Hirota K.
PMID: 26713247
PeerJ. 2015 Dec 10;3:e1498. doi: 10.7717/peerj.1498. eCollection 2015.

Proper glycemic control is one of the most important goals in perioperative patient management. Insulin secretion from pancreatic β-cells in response to an increased blood glucose concentration plays the most critical role in glycemic control. Several animal and human...

Overview of the genetic determinants of primary aldosteronism.

The application of clinical genetics

Al-Salameh A, Cohen R, Desailloud R.
PMID: 24817817
Appl Clin Genet. 2014 Apr 08;7:67-79. doi: 10.2147/TACG.S45620. eCollection 2014.

Primary aldosteronism is the most common cause of secondary hypertension. The syndrome accounts for 10% of all cases of hypertension and is primarily caused by bilateral adrenal hyperplasia or aldosterone-producing adenoma. Over the last few years, the use of...

Role of endothelium-dependent hyperpolarisation and prostacyclin in diabetes.

The Malaysian journal of medical sciences : MJMS

Mokhtar SS, Rasool AH.
PMID: 26023290
Malays J Med Sci. 2015 Mar-Apr;22(2):8-17.

The endothelium plays a crucial role in maintaining vascular homeostasis by producing several vasodilating factors, including nitric oxide (NO), prostacyclin (PGI2), and endothelium-dependent hyperpolarisation (EDH); however, the balance between endothelial relaxing and contracting factors is disrupted in disease states...

The Natural Flavone Acacetin Blocks Small Conductance Ca.

Frontiers in pharmacology

Chen KH, Liu H, Sun HY, Jin MW, Xiao GS, Wang Y, Li GR.
PMID: 29081746
Front Pharmacol. 2017 Oct 10;8:716. doi: 10.3389/fphar.2017.00716. eCollection 2017.

The natural flavone acacetin inhibits several voltage-gated potassium currents in atrial myocytes, and has anti-atrial fibrillation (AF) effect in experimental AF models. The present study investigates whether acacetin inhibits the Ca

Large-Conductance Calcium-Activated Potassium Channels in Glomerulus: From Cell Signal Integration to Disease.

Frontiers in physiology

Tao J, Lan Z, Wang Y, Hei H, Tian L, Pan W, Zhang X, Peng W.
PMID: 27445840
Front Physiol. 2016 Jun 21;7:248. doi: 10.3389/fphys.2016.00248. eCollection 2016.

Large-conductance calcium-activated potassium (BK) channels are currently considered as vital players in a variety of renal physiological processes. In podocytes, BK channels become active in response to stimuli that increase local cytosolic Ca(2+), possibly secondary to activation of slit...

hERG S4-S5 linker acts as a voltage-dependent ligand that binds to the activation gate and locks it in a closed state.

Scientific reports

Malak OA, Es-Salah-Lamoureux Z, Loussouarn G.
PMID: 28273916
Sci Rep. 2017 Mar 02;7(1):113. doi: 10.1038/s41598-017-00155-2.

Delayed-rectifier potassium channels (hERG and KCNQ1) play a major role in cardiac repolarization. These channels are formed by a tetrameric pore (S5-S6) surrounded by four voltage sensor domains (S1-S4). Coupling between voltage sensor domains and the pore activation gate...

In vitro effects of extracellular hypercapnic acidification on the reactivity of rat aorta: Rat aorta vasodilation during hypercapnic acidification.

Nitric oxide : biology and chemistry

de Nadai TR, de Nadai MN, Cassiano Silveira AP, Celotto AC, Albuquerque AA, de Carvalho MT, Scarpelini S, Rodrigues AJ, Evora PR.
PMID: 26358824
Nitric Oxide. 2015 Nov 15;50:79-87. doi: 10.1016/j.niox.2015.09.001. Epub 2015 Sep 07.

The mechanisms by which pH influences vascular tone are not entirely understood, but evidence suggests that the endothelium is involved. Here, we aimed to study the in vitro vascular responses induced by extracellular hypercapnic acidification (HA), as well as...

Cross-talk and regulation between glutamate and GABAB receptors.

Frontiers in cellular neuroscience

Kantamneni S.
PMID: 25914625
Front Cell Neurosci. 2015 Apr 10;9:135. doi: 10.3389/fncel.2015.00135. eCollection 2015.

Brain function depends on co-ordinated transmission of signals from both excitatory and inhibitory neurotransmitters acting upon target neurons. NMDA, AMPA and mGluR receptors are the major subclasses of glutamate receptors that are involved in excitatory transmission at synapses, mechanisms...

ATP-dependent potassium channels are implicated in simvastatin pretreatment-induced inhibition of apoptotic cell death after renal ischemia/reperfusion injury.

Medical journal of the Islamic Republic of Iran

Front Comput Neurosci. 2015 Jul 06;9:86. doi: 10.3389/fncom.2015.00086. eCollection 2015.

This study used the Frankenhaeuser-Huxley axonal model to analyze the effects of non-symmetric waveforms on conduction block of myelinated axons induced by high-frequency (10-300 kHz) biphasic electrical stimulation. The results predict a monotonic relationship between block threshold and stimulation...
