Spontaneous fluctua- tions of excitability in the muscle spindle of the frog. The concept of hormesis radiation is normally applied to radiation doses in the range of 1 to 50 Gywhich means, radiation doses that instead of provoking irreparable damage that would lead to cellular death, would provoke a radioadaptative response that would benefit the cell and its descendant , . Behavioral modulation of tactile responses in the rat somatosensory sys- tem.
Components of re- ceptor adaptation in a Pacinian corpuscle. At the present work possible transformations on E. The exercised skeletal mus- cle: Morphological and physiological alterations occurred in Escherichia coli E. The prokaryotes compose an interesting group of microorganisms, which can be used as instruments boifisica scientific investigation.

Motor-unit discharge rates in maximal voluntary con- biofisida of three human muscles. Loewenstein WR, Mendelson M. Heneihe of cat moto- neurons to sustained and intermittent extracellular activation. Coli cells elongated after irradiation with UVc as well as with proton beam. For the radiation with proton beams the absorbed doses ranged from 0.

Adaptation of the dis- charge of frog muscle spindles following a stretch. Analysis of impulse adaptation in motoneurons.
The cells were then centrifugated rpm15 minutes and resuspended in solution of NaCl 0. The biochemical test carried out was the following: Enviado por Gabriel flag Denunciar. Vogues-Proskauer, Indol production, descaboxilation of L-lisina, glucose fermentation, lactose fermentation, rhamnose fermentation, urea hydrolysis, H 2 S production, citrate and ornitine , .
Prokaryote cells were exposed to ultra violet UVc radiation and to proton beams in order for the induced effects to be studied. Some mutations are undesirable and even lethal, however, some can be interesting for the survival of a species , , .
Neural control in human muscle fa- tigue: Motoneurone properties and motor fatigue. This can be provoked by UVc radiation that induces the formation of pyrimidine dimers in the cellular DNA or by beams of protons it can dislocate electrons of the atoms and create highly reactive ions that can attack biomolecular constituents of the cell, including the DNA , .
This solution was used to make the dilutions of which 0. Brokensha G, Westbury DR. In the literature the elongation phenomenon of E. The tests should be rechecked and it would perhaps be necessary to increase the corpuscular radiation dose proton beams applied to the E.
This can be explained by the fact that they possess intrinsic properties, such as reduced time of generation and relatively low cost of culture and maintenance , . A model illustrating some aspects of muscle spindle physiology. As for the exposition with proton beam, it was also possible to observe that the cells were elongated as can be seen in Figs.
The induction of N-methyl-D-aspar- tate receptor-dependent long-term potentiation. Coli cells lost some basic biochemical properties when the received doses were in the range of 0.
Time course and properties of late adaptation in spinal motoneurones of the cat.

A cellular survival curve versus exposition time and absorbed dose was built for each case. The components of mem- brane conductance in the giant axon of Loligo.
Principles of electric circuits, electron flow version.
Changes in motoneurone firing rates during sustained maximal voluntary contractions. With the experiments described above it was possible to conclude that: It is an important biotechnological tool, which makes it possible to obtain important parameters for the metabolic heneinf genetic hheneine of cells of more complex organisms.
Inhibition of impulse activity in a sensory neuron by an electrogenic pump. Evidence for saltatory conduc- tion in peripheral myelinated nerve bifisica. The occurrence of morpho-physiologic alterations in the cells of E. A brief history of myelinated nerve fi- bers: Services on Demand Journal.
For the irradiation with UVc radiation a dilution of 1: This antibiotic intervenes in the synthesis of the peptidoglycan of the cell’s wall, resulting in the incapacity of the cell to divide, without provoking its death .
In the Gram-stain the E. Energy-efficient action po- tentials in hippocampal mossy fibers. Figure 1 shows the plot of the survival fraction versus the exposition time to the UVc beam, while Fig.
