In the current report, we review many morphologic, clinical, ultrastructural, molecular and genetic aspects that support the hypothesis of an origin of PEComas from the neural crest.

Morphological identification of neuron types in the rat hippocampus T. Szilagyi, K. Pavai The cerebral cortex ensures an optimal interaction of mammals, including humans, with their environment, by encoding, storing and combining information about the surrounding world and the internal milieu.

Probably the simplest and the most popular region for studying the cortical network is the hippocampal CA1 area, because it has the least heterogeneous neuronal population, the somata and dendrites of principal papillary urothelial cell proliferation pyramidal cells are arranged into well defined layers and the extrinsic and intrinsic inputs are segregated. The relatively homogeneous pyramidal cell population is supported by a very heterogeneous GABAergic interneuron population, which provides not only general inhibition, but also regulates the precise timing of pyramidal cell activity.

Interneurons usually innervate distinct domains of the surface of their target cell. The strategic placement of inhibitory synapses, indicate that GABAergic interneurons belonging to different classes serve distinct functions in the hippocampal network.

Neuron types are usually defined according to various morphological, molecular and physiological features. Under typical experimental conditions only some of these parameters are available, therefore an important scientific question is: which partial measures are sufficient for correct recognition of a class of cell.

By immunohistochemistry it is possible to stain all neurochemically identical neurons in a given brain region, therefore it is the most widely used method for identifying neuron tip panglică largă. This review presents the neuron types identified so far in the area CA1 of the rat hippocampus with special emphasis on the immunocytochemical characterization of these cells.

Man COPD is a disease characterized by inflammation both in its stable phase and during exacerbations. Inflammation is present in the respiratory compartment, the inflammatory cells and different mediators of inflammation being present. Studies have shown that some mediators of inflammation have a high level at systemic level also, inducing a certain grade of systemic inflammation, mainly responsible for the systemic manifestation of the disease.

ROMANIAN JOURNAL of MORPHOLOGY and EMBRYOLOGY

It seems that the both local and the systemic inflammation are amplified during exacerbations. The purpose of this paper is to review the respiratory inflammatory reaction, to identify the main actors involved in the stable phase of the disease and during exacerbations, the systemic inflammation accompanying the local inflammation, and to find the possible interrelations between the systemic and local inflammation, on one hand, and the respiratory and extra-respiratory manifestations of COPD on the other hand.

The understanding of the pathogenic mechanisms, which stay at the base of inflammation and of the possible interrelations shown, represents a theoretical interest and also a practical one, concerning the targets of different therapeutic agents which could be used in the management and in the control of the disease.

Clinico-pathological correlations in fatal ischemic stroke. An immunohistochemical study of human brain penumbra D. Arsene, Florina Vasilescu, C. Toader, Adina Balan, C. Popa, Carmen Ardeleanu Ischemic stroke is one of the most frequent pathologies with high invalidating potential and a leading cause of death. The brain tissue adjacent to the central necrotic core, defined as penumbra, was extensively characterized mostly by imaging techniques and in animal models.

Our goal was to identify a large panel of molecules in this particular area on human brains harvested at autopsy. Twenty-one patients with ischemic stroke and seven control cases were taken into study. We used immunohistochemistry to characterize necrotic lesions. Metalloproteinases, mostly MMP-9, seem to be involved in brain ischemia, but as a protective and not as a deleterious factor.

Apoptotic molecules are not increasingly expressed in stroke compared to control cases. Mast cell enzymes chymase papillary urothelial cell proliferation tryptase are described for the first time in neurons and glia, even with unclear significance.

Microglia appears active in stroke and stimulating methods directed to it could be useful. Nitric oxide synthases and cyclooxygenase-2 were also involved in stroke cases but not in control ones. Animal study of penumbra and human tissue findings are distinct and research should be focused on the latter approach in order to find valuable and safe therapeutic methods.

Ditescu, V. Gheorghita, E. Crauciuc, Irina-Draga Caruntu Cyclooxygenase 2 COX-2 regulates the prostaglandins production and it seems to have a role in the onset and progression of different malignant tumors, being overexpressed in numerous human malignancies and premalignant conditions.

Some cellular elements from chronic inflammatory processes, together with stromal cells may be involved in neoplastic transformation of proliferative stem cells and in the process of tumor invasion. Cervical carcinoma, as a commonly pattern of different tumors, can express COX-2 in association with glutathione-S-transferase isoenzymes and can be considered as possible molecular targets in antitumoral therapy. Immunostains with COX-2 antibodies were performed on formalin-fixed and paraffin-embedded tissue sections from 20 cervical biopsies: 10 with LSIL histopathologic diagnosis and 10 with HSIL histopathologic diagnosis.

The Allred immunohistochemical score for the intensity of staining and the percent of cells stained was assigned. The slides papillary urothelial cell proliferation scored by three independent pathologists and compared across histological categories. The increase of COX-2 expression in cervical cancer precursors certifies that COX-2 may have a role in the development and progression of cervical squamous intraepithelial lesions.

Evaluation of women knowledge and papillary urothelial cell proliferation regarding cervical cancer early detection Fl. Badulescu, Ileana Prejbeanu, Cornelia Rada, Anca Patrascu, Manuela Dragomir, Florina Carmen Popescu At European level, Romania unfortunately comes first as far as mortality due to cervical cancer is concerned, mortality rate recording a continuous increase due to papillary urothelial cell proliferation detection in advanced stages.

In this context, we followed an assessment of women's cognitive and attitudinal fund in relation to early detection of cervical cancer, through the application papilomuri de tip oncogen a questionnaire on a batch of women with ages from 18 to year-old, with various levels of education, residents of Craiova City and communes from Dolj County. Statistic processing of their answers indicates that Buiga, Ioana Brie, N.

Balacescu Introduction: Despite the improvement in the treatment results due to modern irradiation techniques and to the association of chemo-radiotherapy, cervical cancer remains an unsolved problem of oncology both due to the increased rate of local failures and of the distant metastasis. Efforts to implement new therapeutic strategies in order to obtain better results in patients with cervical cancer appear justified.

Neovascularization is an important step in the tumor progression and the therapeutic targeting of the tumor blood vessels appears to be a good strategy to follow in the anti-cancer treatment.

Thus, even in an incipient phase of the clinical research process, the combination between the anti-angiogenic aimed therapies and the current radio-chemotherapy seems to represent a new, feasible and promising approach. Materials and Methods: So far, 54 women were included in a prospective trial: 44 having an advanced cervical carcinoma and 10 healthy women, as controls.

A tumor biopsy and a blood sample were obtained from each patient before the start of therapy.

Tumorile vezicale - Papillary urothelial malignant

The quantitative polymerase chain reaction Real Time PCR was employed for assessing the expression level of the genes involved. Conclusions: Univariate analysis demonstrates that the response to radio-chemotherapy in cervical cancer is related to a set of clinical and molecular factors as: the tumor size, the expression of VEGFR2 as mRNA level and the patients' age.

Unfortunately, the multivariate analysis by logistic model selects only VEGFR2 expression for prediction of tumor response. The interrelations between the different biomarkers demonstrate the complexity of the tumor progression process and the necessity of further studies to identify new therapeutic targets.

The vasculogenesis - a possible histological identification criterion for the molar pregnancy Liliana Novac, Mihaela Niculescu, Maria Magdalena Manolea, D. Iliescu, Claudia Valentina Georgescu, Al. Comanescu, N. Cernea, Andreea Enache The benign hydatidiform mole partial and complete practically represents an associated pathology of the first trimester miscarriage; it is considered that it represents the initial pathology, which, evolutionally, may be followed by the dacă copilul tău a tratat viermi of invasive mole and choriocarcinoma.

The authors have studied clinical and cytogenetical 61 cases selected according to some specific criteria for the suspicion of molar pregnancy or hydropic abortion and 21 cases that represented the control group made by patients with normal pregnancy which have been presented for legal abortion. In all cases has been made a histological exam and has been studied the vasculogenesis by immunohistochemistry labeling for CD31 and CD Following-up the results has been established a number of histological and cancer genital cauze criteria for papillary urothelial cell proliferation evaluation and differentiation of various molar pregnancy types and the vasculogenesis characteristics.

The most important differential diagnosis criteria between partial and complete mole is represented by the trophoblast disposition and the atypical trophoblast in the complete mole. Thus, although the expression of transcription factors is very heterogeneous, their simultaneous implementation for positive and differential diagnosis may be useful.
