Cell synchronization is a process by which cells in a culture at different stages of the cell cycle are brought to the same phase. Cell synchrony is a vital process in the study of cells progressing through the cell cycle as it allows population-wide data to be collected rather than relying solely on single-cell experiments.
Obtaining a culture with a unified cell-cycle stage is useful for biological research where a particular stage in the cell cycle is desired (such as the culturing of parasitized cells [3]). Since cells are too small for certain research techniques, a synchronous culture can be treated as a single cell; the number of cells in the culture can be ...
In some experiments, a researcher may want to control and synchronize the time when a group of cells progress to the next phase of the cell cycle. [5] The cells can be induced to arrest as they arrive (at different time points) at a certain phase, so that when the arrest is lifted (for instance, rescuing cell cycle progression by introducing another chemical) all the cells resume cell cycle ...
The cell cycle is a series of complex, ordered, sequential events that control how a single cell divides into two cells, and involves several different phases. The phases include the G1 and G2 phases, DNA replication or S phase, and the actual process of cell division, mitosis or M phase. [ 1 ]
The episode aired in the United States on April 13, 1997, on the Fox network. The episode is a "Monster-of-the-Week" story, a stand-alone plot, unconnected to the series' wider mythology. "Synchrony" earned a Nielsen rating of 11.3, being watched by 18.09 million people upon its initial broadcast. The episode received mixed to positive reviews ...
The best studied rhythm in chronobiology is the circadian rhythm, a roughly 24-hour cycle shown by physiological processes in all these organisms.The term circadian comes from the Latin circa, meaning "around" and dies, "day", meaning "approximately a day."
In 1973, M. M. Taylor [1] suggested that if synapses were strengthened for which a presynaptic spike occurred just before a postsynaptic spike more often than the reverse (Hebbian learning), while with the opposite timing or in the absence of a closely timed presynaptic spike, synapses were weakened (anti-Hebbian learning), the result would be an informationally efficient recoding of input ...
In electrical engineering terms, for digital logic and data transfer, a synchronous circuit requires a clock signal.A clock signal simply signals the start or end of some time period, often measured in microseconds or nanoseconds, that has an arbitrary relationship to any other system of measurement of the passage of minutes, hours, and days.
