Possible Role of N-Methyl-D-Aspartate Glutamate Receptors in The Induction of Acrosome Reaction in Human Sperm [PDF]
Cell JournalObjective: Acrosome reaction is a receptor and Ca2+-dependent process. N-Methyl-D- aspartate (NMDA) glutamatereceptors are expressed in the human sperm and are involved in the Ca2+ influx.

Ca2+ Dependence of the Ca2+-selective TRPV6 Channel [PDF]
Journal of Biological Chemistry, 2004 Microfluorimetry and patch-clamp experiments were performed on TRPV6-expressing HEK cells to determine whether this Ca(2+)-sensing Ca(2+) channel is constitutively active. Intact cells loaded with fura-2 had an elevated intracellular free Ca(2+) concentration ([Ca(2+)](i)), which decreased to the same level such as in non-transfected cells if external ...

Endothelin-Induced Sarcoplasmic Reticulum Calcium Depletion Waves in Vascular Smooth Muscle Cells [PDF]
, 2011 Agonist-stimulated waves of elevated cytoplasmic Ca2+ concentration ([Ca2+]i ) regulate blood vessel tone and vasomotion in vascular smooth muscle. Previous studies employing cytoplasmic Ca2+ indicators revealed that these Ca2+ waves were generated by a ...

Saltatory Propagation of Ca2+ Waves by Ca2+ Sparks [PDF]
Biophysical Journal, 1998 Punctate releases of Ca2+, called Ca2+ sparks, originate at the regular array of t-tubules in cardiac myocytes and skeletal muscle. During Ca2+ overload sparks serve as sites for the initiation and propagation of Ca2+ waves in myocytes. Computer simulations of spark-mediated waves are performed with model release sites that reproduce the adaptive Ca2 ...

Role of adenosine triphosphate and protein kinase A in the force-frequency relationship in isolated rat cardiomyocytes [PDF]
Archives of Biological Sciences, 2023 The physiological heart rate of rodents is around 4-6 Hz, although a stimulus frequency of 1 Hz is generally used in isolated cardiomyocytes to study changes in the contraction-relaxation cycle in cardiac muscle physiology and pathophysiology.

Evidence for the role of sound on the growth and signal response in duckweed
Plant Signaling & Behavior, 2023 Sound vibration, an external mechanical force, has been proven to modulate plant growth and development like rain, wind, and vibration. However, the role of sound on plants, especially on signal response, has been usually neglected in research.
