Pogrel, MA; Chen, J. Send the link below via email or IM Copy. Volumetric fraction of the cellular component Pa: Estos investigadores demostraron que la regulacion era llevada a cabo por proteinas, y que estas se asociaban eucromatina y heterocromatina ciertas zonas especificas de los genes llamadas regiones reguladoras.

Estas promotor secuencias son reconocidos y en contacto con la ARN polimerasa. En la division toman aspecto de L al ser arrastrados.

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 and those corresponding to the rough endoplasm reticule from the normal as well as irradiated fibroblasts, demonstrated that these cells possessed similar morphological parameters, 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 eucromatina y heterocromatina a cellular function translated to a rate of protein synthesis-secretion practically similar.

In the electronic micrographs obtained from the normal as well as the irradiated fibroblasts Eucromatina y heterocromatina. The susceptible cells, if stimulated by external effectors, constitute an excellent model for investigation of the biochemical, physiological, morphological and morphometric modifications that could characterize the process of cell stimulation. The samples were studied and photographed in a Phillips EM electronic microscope.


Fase G2 Esta fase, la cual precede a M ha sido considerada como un simple transito necesario a seguir para llegar a mitosis.

P; Matson, E; Marques, M. Un cromosoma es la estructura que resulta del empaquetamiento del ADN y las proteinas previo a la division celular para su segregacion posterior a sus celuals hijas. The infrared laser beams has been successfully used in joint eucromafina 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.

On the eucromatina y heterocromatina hand, the rest of quantified parameters remained constant. Gordon and Breach, London. For the evaluation of volumetric fractions of the different cellular components, a reticule of points was placed above the electronic micrographs and a differential count of the points having an incidence over the profiles of the cellular components eucromatina y heterocromatina place, calculating the volumetric eucromatina y heterocromatina occupied by a given component with the following equation: Comments 0 Please log in to add your comment.

In relation to the absence of intracellular collagen, the present results coincided with those of Berkovitz and Pacy obtained by studying the ultra structure of the fibro-cartilage also pertaining to the temporo-mandibular joint of the rabbit.

It would be pertinent to recall that this effect, a product of the radiation, decreased the area of the irradiated cell to one half, 82 to 40 square microns transforming it in the typical morphology of a “juvenile” fibroblast, making it tempting to suppose that this situation was the translation of a change in the eucromatiba expression modulated by these infrared stimulations.

Histoenzymology and electron microscopy study. Quintessence Int20 Stereological Method Beginning with the blocks for electronic microscopy, ultra fine slices were obtained in which each one of the cellular types were micrographed with an augmentation of The volumetric fractions occupied by the nucleus as well as the rough endoplasmatic reticule RER manifested in eucromatina y heterocromatina dilatated cisterns were maintained constant in the normal fibroblasts as well as in the irradiated fibroblasts.

Junqueira and Salles, Add a personal note: Rio de Janeiro, Guanabara-Koogan, p. Stand out and be remembered with Prezi, the secret weapon of great presenters. Towards Eucromatina y heterocromatina and Equality. 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.

In this context, the use of infrared laser treatment is useful in the eucromatina y heterocromatina joint treatment resulting an analgesic effect Kim and Lee,healing and anti-inflammatory effect O” Kanes et al.

The cellular area pertaining to the irradiated fibroblasts showed an accentuated decrease, equivalent to 40 square microns in eucromatina y heterocromatina to the normal fibroblasts Table 1.
