Function of P2X4 Receptors Is Directly Modulated by a 1:1 Stoichiometric Interaction With 5-HT3A Receptors

Frontiers in Cellular Neuroscience, 2020
Interacting receptors at the neuronal plasma membrane represent an additional regulatory mode for intracellular transduction pathways. P2X4 receptor triggers fast neurotransmission responses via a transient increase in intracellular Ca2+ levels.

Stoichiometry of carbon, nitrogen, and phosphorus in wastewater from Romania

Romanian Journal of Ecology & Environmental Chemistry, 2021
Water resources crisis can lead to a new concept of wastewater treatment. Wastewater cannot be considered waste, but can be a renewable or non-renewable energy source. Nutrients from wastewater could be recycled and not disposed of.

Stoichiometry

Con-Ciencia Boletín Científico de la Escuela Preparatoria No. 3, 2023
La estequiometría se utiliza en nuestra vida cotidiana no solo en las industrias, nos permite identificar cuánta materia prima se necesita para que un producto quede en las mejores condiciones sin desperdiciar sustancias. La estequiometría se refiere a las relaciones entre átomos, moles y partículas elementales en una reacción química; por ejemplo, en

Pelagic community production and carbon-nutrient stoichiometry under variable ocean acidification in an Arctic fjord [PDF]

, 2013
Net community production (NCP) and carbon to nutrient uptake ratios were studied during a large-scale mesocosm experiment on ocean acidification in Kongsfjorden, western Svalbard, during June–July 2010. Nutrient depleted fjord water with natural plankton
