These cells were used rather than square Pyrex tubing because of the tendency of the latter to shatter when thawing frozen carbon tetrachloride.

These antibody titers were determined by reaction with homozygous Af red cells.

These cells were thawed at 37-degrees-C for 30 min and were deglycerolized by alternately centrifuging and mixing with descending concentrations of glycerol solutions ( 20, 18, 10, 8, 4 and 2% ).

These protists live as individual amoebae until starved, at which point they aggregate and form a multicellular fruiting body in which some cells sacrifice themselves to promote the survival of other cells in the fruiting body.

These particles continue to decay, emitting alpha particles which can damage cells in the lung tissue.

These antigens can sometimes be presented by tumor cells and never by the normal ones.

These are released by lysis of the host cells and group together by syzygy.

These secrete enzymes that allow the parasite to enter other cells.

These molecules mark the cell for phagocytosis by cells possessing the appropriate receptors, such as macrophages.

These two inhibitory proteins are partially responsible for HeLa cells immortality by inhibiting apoptosis to occur.

These bacteria also secrete proteins that enable the AC-II to enter host cells, where the exogenous AC activity undermines normal cellular processes.

These oxidants can damage cells by starting chemical chain reactions such as lipid peroxidation, or by oxidizing DNA or proteins.

These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.

These same compounds also increase secretion of macrophage colony-stimulating factor by osteoblasts, which promotes the differentiation of progenitor cells into osteoclasts, and decrease secretion of osteoprotegerin.

These domains reflect whether the cells have nuclei or not, as well as differences in the chemical composition of the cell exteriors and ribosomes.

These tailor-made drugs promise not only to maximize therapeutic effects but also to decrease damage to nearby healthy cells.

These include the use of genetic information in reproductive decision-making and the possibility of genetically altering reproductive cells that may be passed on to future generations.

These are epithelial cells that are coated with bacteria.

These proteins are often concentrated in specialized cells and in cell corners.

These ideas include the proposal that cells contain zones of low and high-density water, which could have widespread effects on the structures and functions of the other parts of the cell.

These can take part in self-perpetuating circuits in the gene regulatory network, circuits that can involve several cells that communicate with each other.

These cells and the bacteria trapped inside them entered a symbiotic relationship, a close association between different types of organisms over an extended time.

These principles are motivated by neuroscience insights about learning at the level of nerve cells ( synaptic plasticity ) and the coupling between cortical systems for language and action in the human brain.

These effects are likely mediated in the inferior olive, specifically at low-threshold calcium channels ( LTCC ) which have been shown to modulate the rhythmic firing of cells in this area.

These things both express and, at the same time, continue contributing to, their identity diffusion in an area that could have become a source of developing dignity and self-certainty.

These three express in divine Science the threefold, essential nature of the infinite.

These nonce orders all express the " speaking architecture " ( architecture parlante ) that was taught in the Paris courses, most explicitly by Étienne-Louis Boullée, in which sculptural details of classical architecture could be enlisted to speak symbolically, the better to express the purpose of the structure and enrich its visual meaning with specific appropriateness.

These equations express mathematically that, in the case of an object that moves along a circular path with a changing speed, the acceleration of the body may be decomposed into a perpendicular component that changes the direction of motion ( the centripetal acceleration ), and a parallel, or tangential component, that changes the speed.

These minutes correspond to the Latin diei scrupulis, and used to express periods of planetary motions.

These words express the deep and respectable knowledge that Palaestrio has of the Latin language.

These outcomes occur because giving some passengers full express services means bypassing often large numbers of passengers at intermediate stations along the corridors.

These are quantities that express the local state of the system, besides the usual local thermodynamic variables ; in a sense such variables might be seen as expressing the ' memory ' of the materials.

These words must be factual yet entertaining as the Count states, “ then, it is necessary to arrange what is to be said or written in its logical order, and after that to express it well in words that, if I am not mistaken, should be appropriate, carefully chosen, clear and well formed, but above all that are still in popular use " ( Courtier 77 ).

These myths also express some hope that the idyllic state of affairs they describe is not irretrievably and irrevocably lost to mankind, that it can be regained in some way or other.

These words and terms were used because of their familiarity, but more so because in most cases there were no equivalent terms in the vernacular which could express the Jewish concepts or describe the objects of cultural significance.

These complications mean that there are three common ways to express a polynomial as an integer: the first two, which are mirror images in binary, are the constants found in code ; the third is the number found in Koopman's papers.

The path loss for the first ten kilometers may be 150 -- 190 dB ( Note: These values are very approximate and are given here only as an illustration of the range in which the numbers used to express the path loss values can eventually be, these are not definitive or binding figures -- the path loss may be very different for the same distance along two different paths and it can be different even along the same path if measured at different times.

These few words succinctly express the missionary nature of the Church ".

" These symbols express a self-view of the Prieneians as a maritime democracy aligned with Athens but located in Asia.

These demonstrate his attempt to express the tension between the static stone and the dynamic desires of the figures represented emerging into solidity from it.

These included express coach ( Transport Act 1980 ), British Telecom ( completed in 1984 ), privatisation of London bus services ( 1984 ), local bus services ( Transport Act 1985 ) and the railways ( 1993 ).

These cells are also known as CD4 < sup >+</ sup > T cells because they express the CD4 protein on their surface.

These cells are also known as CD8 < sup >+</ sup > T cells since they express the CD8 glycoprotein at their surface.

These self-antigens are expressed by thymic cortical epithelial cells that express Activation-Induced ( Cytidine ) Deaminase on both MHC molecules on the surface of cortical cells.

These, along with the similar British Rail Class 86 | Class 86 formed the backbone of express passenger services on the WCML from the 1970s until the 2000s.

These vehicles remained the mainstay of the WCML's express services until the early 2000s.

" These phrases express the idea that the totem always accompanies, belongs to, and stands behind one as a guide and warner of dangers.
