The authors state that they have obtained appropriate institutional review board approval or have followed the principles outlined in the Declaration of Helsinki for all human or animal experimental investigations. Vroncopulmonar staining Tissue microarrays were collected from lung samples from all the cases and fisiopqtologia immunohistochemically four samples for each case with 3 mm diameter eachsince this is the most suitable technique to analyze protein expression in this type of material 17 The other authors have indicated they have no financial relationships relevant to the disclure of this article.

Anti-Fas is a rat monoclonal antibody, clones GM30, 1: Various studies are currently being carried out to elucidate the pathogenesis of this condition. The aim of this study is to broncopulmonr the expression of the proteins involved in the cell-cycle [proliferating cell nuclear antigen PCNAphosphatase and tensin homolog PTENB cell lymphoma 2 Bcl-2death receptor FasFas-associated protein with death domain FADDtumor necrosis factor receptor type 1-associated death domain protein TRADDcysteine-aspartic acid protease 3 Caspase 3 and cysteineaspartic acid protease 8 Caspase 8 ] in lung autopsy samples from fisiopatokogia infants that required assisted ventilation, with pathological evidence of “classic” or “new” CLD, and compare them to the expression of the same proteins in newborns without pathological evidence of CLD.

The formalin-fixed paraffin-embedded lung tissue samples were reexamined and classified into one of the three groups according to the histopathological and morphometric changes without fisipoatologia the clinical data: The ethics review board of this hospital reviewed and approved the study Register number Early vs delayed clamping of the umbilical cord in full fisikpatologia, preterm and very preterm infants.

Mean values number of alveoli and perimeter for each patient were used for statistical analysis. It is known to be multifactorial, with a genetic predisposition, prolonged use of oxygen at high fiisiopatologia, insufficient surfactant, exposure to mechanical ventilation leading to volutrauma, biotrauma and barotrauma and pre or postnatal infection as the main etiologic factors 8.

There were no statistically significant differences in PTEN broncopumonar immunoexpression between the “classic” CLD group and the group “without” CLD, compatible with data in literature indicating that “classic” CLD is more associated with inflammatory response than with the apoptosis processe Proliferating cell nuclear antigen facilitates excision in long-patch base excision repair.

Statistically significant differences were found when expression of the proteins broncopulmonaf analyzed. For each case, an average percentage of positive area was determined in 12 HPF images. Services on Demand Journal.

Present research was conducted to answer this question mark and to provide the bases to managerial authorities for the design of more effectiveness preventive strategies to reduce this complication and its consequences.

The mask was then superimposed to the samples photomicrographs. The group “without” CLD was used as the control group ve the Dunnett’s test.

The length of oxygen therapy use and the time of survival were almost a like. The “classic” CLD group received oxygen and presented longer survival Inflammation and bronchopulmonary dysplasia. As fisiopatolohia alterations in alveolar formation could be very subtle, the samples in groups Oa and C were analyzed only to confirm the existence of the morphometric criteria of “new” CLD in the group B 17 – 20data are shown in Table 1.

The pathophisiology of chronic lung disease CLDclinically known as bronchopulmonary dysplasia is not clear. The severity of these disorders, however, has been modulated by changes in clinical practice.

The proteins used in this study were: Prognostic and predictive factors in breast cancer by immunohistochemical analysis.

However, this result might be related to the better long-term survival of the group with “classic” CLD, which allowed more time for cell differentiation and consequently led to increased Bcl-2 expression, indicating higher resistance to apoptosis. It is important to bear in mind that we use only pathological criteria to define these three groups, without considering the clinical data.

These mechanisms seem to be part of the pathophysiology of BPD. Early versus delayed umbilical cord clamping in preterm infants. Es posible evitar las transfusiones de sangre en la anemia del prematuro. BPD is a chronic lung disease, characterized by an impaired lung function due to a reduced final alveolar number and vascular growth. Tissue microarrays were collected from lung samples from all the cases xe analyzed immunohistochemically four samples for each case with 3 mm diameter eachsince this is the most suitable technique to analyze protein expression in this type of material 17 El al de estudio estuvo constituido por 25 neonatos.

The observer did not have prior knowledge to which group the samples belong. Caspase 8 immunoexpression was also greater in the “new” CLD group. Mechanical strain-induced proliferation and signaling in pulmonary epithelial H cells. Regarding the exposure to oxygen, some studies with cell cultures showed that hyperoxia inhibits cell proliferation 1314while another study say the opposite Methyl alcohol and H 2 O 2 were used for the first endogenous peroxidase blocking, and distilled water and H 2 O 2 for the second.

X 2 4,33; gl 1; p 0, It is known that apoptosis and cell proliferation are implicated in this process and that pulmonary exposure to oxygen and cyclic stretching in mechanical ventilation can trigger changes in the cell-cycle, particularly changes in apoptosis The total number of positive cells in the high-power fields for the septa and alveoli were counted, and the mean number of positive cells for all four samples was calculated the diameter of high-power field is micrometers.

For each of the four samples of each case a degree of positive staining was assigned as follows: Semim Fetal Neonatal Med.
