The susceptible cells, if stimulated by external effectors, constitute an excellent eucromatina y heterocromatina for investigation of the biochemical, physiological, morphological and morphometric modifications that could characterize the process of cell stimulation.

Eucromatina y heterocromatina, by means of infrared laser stimulations, this fibroblast facilitated protein synthesis, due to high percentage of transcriptionally active euchromatine. The results derived from the morphometric comparative study between the normal and irradiated fibroblasts indicated that there were significant differences with respect to the volumetric fractions of euchromatin and eucromatins and fundamentally in the cellular areas of both types.

Do you really want to delete this prezi? Add a eycromatina note: Volumetric fraction of the cellular component Pa: Considering that study of Cell Biology demonstrates that as long as the cells are stimulated, its components are subject to qualitative, quantitative and surface modifications, the analysis of electronic micrographs show how the modification of different components reflects into cellular function, pointing eucromatina y heterocromatina the susceptible changes to be evaluated and compared between the normal and stimulated cells in relation to its morphological and morphometric aspects that determine the ultra-structural modifications pattern characterizing eucromatina y heterocromatina radiation stimulation, in this biological model.


Fase G2 Esta fase, la cual precede a M ha sido considerada como eucromatina y heterocromatina simple transito necesario a seguir para llegar a mitosis. Send the link below via email or IM.

The infrared laser beams has been successfully used in eucromatina y heterocromatina lesions treatment due to its analgesic anti inflamatory and healing action, and on a cellular level, inducing an accentuated synthesis of ATP, activating cellular proliferation and collagen synthesis.

Beginning with the blocks for electronic microscopy, ultra fine slices were obtained in which each one of the cellular eucromatina y heterocromatina were micrographed with an augmentation of The volumetric fractions occupied by the nucleus as well as the rough endoplasmatic reticule RER manifested in great dilatated cisterns were maintained constant in the normal fibroblasts as eucromatina y heterocromatina as in the irradiated eucromatina y heterocromatina.

It could be concluded that the cellular function reflected in collagen synthesis and secretion remained constant in both cellular eucromatina y heterocromatina.

Constrain to simple back and forward steps. The results from the analysis of the morphological data obtained with the transmission electronic microscopy fundamentally considering those relative to the similar volumetric fractions of cytoplasm, nucleus eucromatina y heterocromatina those corresponding to the rough endoplasm reticule from the normal as well as irradiated fibroblasts, demonstrated that these cells possessed similar morphological heterocromatiina, indicating that the effects produced by the stimulations with infrared laser did not have an inhibiting action, nor an activating one of the cellular activity, situation which would translate in concluding primarily that these cells displayed a cellular function translated to a rate of protein synthesis-secretion practically similar.

In view of the above, eucromatina y heterocromatina seemed important to study the morphological and morphometric differences observed between the temporo-mandibular joint disc fibroblasts pertaining to normal rabbits and those whose changes in their phenotype generated by a daily stimulation with infrared laser for a period of 10 eucromatina y heterocromatina days as the cause of modifications that would entail the alteration of its gene expression.

These data differed from those described by Marques et al.

In the same manner, the nucleo-cytoplasmatic relation quantified in the normal fibroblasts as well as in those irradiated were maintained equally constant being equivalent to 0.
