Cell cortexThe cell cortex, also known as the actin cortex, cortical cytoskeleton or actomyosin cortex, is a specialized layer of cytoplasmic proteins on the inner face of the cell membrane. It functions as a modulator of membrane behavior and cell surface properties. In most eukaryotic cells lacking a cell wall, the cortex is an actin-rich network consisting of F-actin filaments, myosin motors, and actin-binding proteins. The actomyosin cortex is attached to the cell membrane via membrane-anchoring proteins called ERM proteins that plays a central role in cell shape control.
Stress–strain curveIn engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength and the ultimate tensile strength. Generally speaking, curves representing the relationship between stress and strain in any form of deformation can be regarded as stress–strain curves.
Institutional racismInstitutional racism, also known as systemic racism, is defined as policies and practices that exist throughout a whole society or organization that result in and support a continued unfair advantage to some people and unfair or harmful treatment of others based on race. It manifests as discrimination in areas such as criminal justice, employment, housing, healthcare, education and political representation. The term institutional racism was first coined in 1967 by Stokely Carmichael and Charles V.
Rho-associated protein kinaseRho-associated protein kinase (ROCK) is a kinase belonging to the AGC (PKA/ PKG/PKC) family of serine-threonine specific protein kinases. It is involved mainly in regulating the shape and movement of cells by acting on the cytoskeleton. ROCKs (ROCK1 and ROCK2) occur in mammals (human, rat, mouse, cow), zebrafish, Xenopus, invertebrates (C. elegans, mosquito, Drosophila) and chicken. Human ROCK1 has a molecular mass of 158 kDa and is a major downstream effector of the small GTPase RhoA.
Societal racismSocietal racism is a type of racism based on a set of institutional, historical, cultural and interpersonal practices within a society that places one or more social or ethnic groups in a better position to succeed and disadvantages other groups so that disparities develop between the groups. Societal racism has also been called structural racism, because, according to Carl E. James, society is structured in a way that excludes substantial numbers of people from minority backgrounds from taking part in social institutions.
Cultural racismCultural racism, sometimes called neo-racism, new racism, postmodern racism, or differentialist racism, is a concept that has been applied to prejudices and discrimination based on cultural differences between ethnic or racial groups. This includes the idea that some cultures are superior to others or in more extreme cases that various cultures are fundamentally incompatible and should not co-exist in the same society or state.
