The release of a mature ovum/oocyte from an ovary.

Any process that activates or increases the frequency, rate or extent of smooth muscle contraction.

Any process that activates or increases the frequency, rate or extent of calcium-mediated signaling.

The movement of a neutrophil within or between different tissues and organs of the body.

The multiplication or reproduction of endothelial cells, resulting in the expansion of a cell population. Endothelial cells are thin flattened cells which line the inside surfaces of body cavities, blood vessels, and lymph vessels, making up the endothelium.

A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.

The multiplication or reproduction of cells, resulting in the expansion of a cell population.

Any process that modulates the frequency, rate or extent of proton transport into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.

The enzymatic generation of superoxide, the superoxide anion O2- (superoxide free radical), or any compound containing this species, by a cell in response to environmental stress, thereby mediating the activation of various stress-inducible signaling pathways.

Any process that modulates the binding and fusion of a sperm to the oocyte plasma membrane.

The regulated release of cytokines from a cell. Cytokines are any of a group of proteins that function to control the survival, growth and differentiation of tissues and cells, and which have autocrine and paracrine activity.

A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.

A cytokinesis that involves the function of a set of proteins that are part of the microfilament or microtubule cytoskeleton.

The lipid bilayer surrounding the endoplasmic reticulum.
