Intracellular Ca2+ is critical for regulating airway smooth muscle (ASM) tension. A rapid rise in the intracellular Ca2+ concentration ([Ca2+]i) of ASM cells is crucial for modulating the intensity and length of the ASM contraction.

Background: The bronchodilating action of β-agonists depends on the tone of airway smooth muscle or on spasmogen. To estimate the precise intrinsic activity of β-agonists, relaxation responses should be examined on maximally contracted airway smooth ...

Curcuma longa extract exerts a myorelaxant effect on the ileum and colon in a mouse experimental colitis model, independent of the anti-inflammatory effect. [PDF]
BACKGROUND: Curcuma has long been used as an anti-inflammatory agent in inflammatory bowel disease. Since gastrointestinal motility is impaired in inflammatory states, the aim of this work was to evaluate if Curcuma Longa had any effect on intestinal ...

Thrombin Protease-activated Receptor-1 Signals through Gq- and G13-initiated MAPK Cascades Regulating c-Jun Expression to Induce Cell Transformation [PDF]
Although the ability of G protein-coupled receptors to stimulate normal and aberrant cell growth has been intensely investigated, the precise nature of the molecular mechanisms underlying their transforming potential are still not fully understood.

Cellular mechanisms of potassium homeostasis in the mammalian nervous system [PDF]
Double-barrelled ion-sensitive microelectrodes were used to measure changes in the intracellular activities of K+, Na+, and Cl- (aKi, aNai, aCli) in neurones of rat sympathetic ganglia and in glial cells of slices from guinea-pig olfactory cortex.

Diabetes-induced alterations in urothelium function:Enhanced ATP release and nerve-evoked contractions in the streptozotocin rat bladder [PDF]
Up to 80% of patients with diabetes mellitus develop lower urinary tract complications, most commonly diabetic bladder dysfunction (DBD). The aim of this study was to investigate the impact of diabetes on the function of the inner bladder lining ...

Voiding Behavior and Efferent Bladder Function Altered in Mice Following Social Defeat but Not Witness Trauma [PDF]
Psychological stress is associated with bladder dysfunction, however, the local bladder mechanisms affected are not well understood. This study aimed to determine how psychological stress, caused by social defeat or witness trauma, affects voiding ...
