Functional effects of KCNQ K+ channels in airway smooth muscle
Frontiers in Physiology, 2013 KCNQ (Kv7) channels underlie a voltage-gated K+ current best known for control of neuronal excitability, and its inhibition by Gq/11-coupled, muscarinic signaling. Studies have indicated expression of KCNQ channels in airway smooth muscle (ASM), a tissue

Dynamic BOLD functional connectivity in humans and its electrophysiological correlates [PDF]
, 2012 Neural oscillations subserve many human perceptual and cognitive operations. Accordingly, brain functional connectivity is not static in time, but fluctuates dynamically following the synchronization and desynchronization of neural populations.

K-functional and weighted moduli of smoothness
Journal of Approximation Theory, 1990 Les auteurs mettent en évidence des équivalents de la fonctionnelle K, et du module de régularité \(\omega^ r_{\phi}(f,t)_{w,p}\), qui interviennent dans la théorie de l'interpolation, pour des espaces de Sobolev avec poids sur un intervalle de \({\mathbb{R}}\), \(1\leq ...

Boosting BOLD fMRI by K-Space density weighted echo planar imaging [PDF]
, 2013 Functional magnetic resonance imaging (fMRI) has become a powerful and influential method to non-invasively study neuronal brain activity. For this purpose, the blood oxygenation level-dependent (BOLD) effect is most widely used. T2* weighted echo planar

On a Functional Equation Associated with (a,k)-Regularized Resolvent Families
Abstract and Applied Analysis, 2012 Let a∈Lloc1(ℝ+) and k∈C(ℝ+) be given. In this paper, we study the functional equation R(s)(a*R)(t)-(a*R)(s)R(t)=k(s)(a*R)(t)-k(t)(a*R)(s), for bounded operator valued functions R(t) defined on the positive real line ℝ+.

Functional Mechanism of Ginsenoside Compound K on Tumor Growth and Metastasis
Integrative Cancer Therapies, 2022 Ginsenosides, as the most important constituents of ginseng, have been extensively investigated in cancer chemoprevention and therapeutics. Among the ginsenosides, Compound K (CK), a rare protopanaxadiol type of ginsenoside, has been most broadly used ...

Alternating hemiplegia of childhood-related neural and behavioural phenotypes in Na+, K+-ATPase a3 missense mutant mice [PDF]
, 2013 Missense mutations in ATP1A3 encoding Na+,K+-ATPase α3 have been identified as the primary cause of alternating hemiplegia of childhood (AHC), a motor disorder with onset typically before the age of 6 months. Affected children tend to be of short stature

Presenilins Upregulate Functional K+Channel Currents in Mammalian Cells
Neurobiology of Disease, 1998 Mutations in presenilin 1 (PS-1) and presenilin 2 (PS-2) have been linked to early onset, autosomal dominant Alzheimer's disease. Neither the normal function(s) of the presenilins nor their role(s) in mediating the devastating neurological and ...
