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 frequencies are amplified and detected by the FM receiver after each burst of transmitted energy and, after the `` pill '' has been calibrated, precise internal pressure indications can be obtained.

These can trap enemies, who are defeated if the bubble is then burst by the player's spiny back.

These are detected when they reach a scintillator in the scanning device, creating a burst of light which is detected by photomultiplier tubes or silicon avalanche photodiodes ( Si APD ).

These models burst out beyond the pages of the magazines.

These include the Canada burst, heart, downward bomb burst, solo head on crosses, and their signature 9-abreast exit.

These are click trains, which are made of numerous individual clicks, usually broadband signals that change from low value to high value quickly, burst pulses, which are individual clicks with high repetition and can be heard by humans only as a buzzing sound and whistles, which are signals that are pure-tones and whose frequency varies depending on the time.

These four pillars will burst jets of water when the Giants hit a home run, win a game, and at the end of the National Anthem.

These activities popularised the trestle desk as a desk form, and some of this survived after the dot-com burst in the year 2000.

These results produced what Seligman described as " a great burst of enthusiasm about changing homosexuality swept over the therapeutic community " after the results were reported in 1966.

These were in the form of dates of the first occurrence of events such as flowering, bud burst, emergence or flight of an insect.

These weapons, designed to destroy incoming nuclear-armed Soviet bombers even when not scoring a clear hit ( due to the nuclear explosion radius, shock wave and radiation burst ), were the only nuclear weapons in USAF arsenal at the time to be under sole control of their pilots ( during a mission ).

These lakes may burst, creating a hazard for zones below.

These beings are dispelled by daylight, though a strong enough burst of light could sear one to dust.

These, however, exerted larger pressure on the existing cannon and could make it burst, causing the death of the irreplaceable gunner with his crew ( and even kings ).

These sounds are layered with vocals and natural instruments ( guitar and piano are common ) into complex, ever-shifting melodies that, at their best, burst with energy.

These included a microgravity crystallography experiment ; animal species including six mice, and small aquatic and terrestrial organisms ; cosmic ray and particle detectors and a gamma ray burst detectors.

These include 16 bits of requester identification ( PCI bus, device and function number ), 12 bits of burst length, 5 bits of tag ( for associating split transactions ), and 3 bits of additional status.

These racemes burst into great trails of clustered white, violet, or blue flowers in early-to mid-spring.

These new factor ( s ) would have acted either to increase human exposures to SIV, to help it to adapt to the human organism by mutation ( thus enhancing its between-humans transmissibility ), or to cause an initial burst of transmissions crossing an epidemiological threshold, and therefore increasing the odds of continued spread.
