The discovery of adult stem cells represented an important step in regenerative medicine because they no longer raises ethical or legal issues and are more accessible. Only instem cells isolated from adipose tissue were described as multipotent stem cells.

Adipose tissue stem cells benefits in tissue engineering and regenerative medicine are numerous. Development of adipose tissue engineering techniques offers a great potential in surpassing the existing limits faced by the classical approaches used in plastic and aggressive cancer of the lymph nodes surgery.

Adipose tissue engineering clinical applications are wide and varied, including reconstructive, corrective and cosmetic procedures. Nowadays, adipose tissue engineering is a fast developing field, both in terms of fundamental researches and medical applications, addressing issues related to current clinical pathology or trauma management of soft tissue injuries in different body locations.

Regardless of histopathological or molecular subtype, the statistical tests proved that for ILC, the highest D lymphatic microvessels density LMVD was in the peritumoral areas. In classical subtype, the LMVD values were positively correlated with the degree of tumor differentiation and pTNM clinical stages and when these cases were classified based on the molecular criteria the highest recorded values were found in the luminal B subtype. This immunoprofile suggests the existence of a tumor type-specific lymphangiogenesis that may have certain prognostic and therapeutic implications.

The nodular and infiltrative-morpheaform are the most common BCC types in the head and neck region and together with the micronodular subtypes are the most aggressive tumors, because of their tendency to infiltrate the deep subcutis, muscles and even bones.

To explain the local aggressive behavior and their metastatic potential, many studies have been performed to identify the molecular determinants implicated in BCC tumor progression.

For this reason, we investigated the immunohistochemical expression of CXCR4, MMP and beta-catenin expression in six metatypical, eight infiltrative-morpheaform, six micronodular and five superficial facial BCCs. For all three markers, the tumor reactivity varied with the histological type.

The highest reactivity was observed in metatypical subtype, especially at the level of areas with squamous cells differentiation. The lowest reactivity was recorded in micronodular and superficial BCC subtypes. Regardless histological subtype, the tumor reactivity was higher at the advancing edge simptome ale verucilor intestinale additional a strong stromal reaction was noticed for all investigated markers peculiar in fibroblasts, inflammatory cells and endothelial cells.

All these data proved the utility of CXCR4, MMP and beta-catenin immunohistochemical investigation in BCCs both for identification of high-aggressive tumors and to develop novel more efficient therapeutic strategy for these patients by targeting these biomarkers.

Electrical conduction system apoptosis in type II diabetes mellitus S. Rusu, F. Pop Even though apoptosis is known to be associated with various cardiovascular pathologies, its presence in cardiac nodal tissue in adults was only scarcely researched.

Cardiomyocyte apoptosis was associated with diabetic cardiovascular pathology. Our main objective was to test whether programmed cell death is present in nodal tissue in type II diabetes mellitus and, if present to characterize it. The study was designed as a qualitative one. We used autopsy samples of hearts from 10 patients 56 to year-old, male to female ratiopositive for type II diabetes mellitus. Samples from sinoatrial and atrioventricular nodes were stained with Hematoxylin-Eosin.

Motoc In the primary mammary malignant tumors, including in situ carcinoma, it is recommended the carrying out of immunohistochemical diagnosis for the estrogen ER and the progesterone receptors PR. We have studied the ER and the PR expression in malignant tumors, trying to identify the corresponding phenotypes according to the presence of these tumors.

Aggressive cancer in lymph nodes,

We have carried out a study on a total number of 80 carcinomas, divided into two groups: the first one constituted of 54 cases of carcinomas on which we had clinical data, and another group, constituted of 26 cases of mammary carcinoma, where no clinical data was available. We have observed that the values and the distribution of the ER and PR taken from the biopsies made in the patients with mammary carcinoma are influenced by the age and menopausal status. The involvement of growth differentiation factor 5 GDF5 and aggrecan in the epithelial-mesenchymal transition of salivary gland pleomorphic adenoma Anca Stefania Enescu, Cl.

Margaritescu, Monica Mihaela Craitoiu, Aurelia Enescu, Stefania Craitoiu Pleomorphic adenoma is the most common salivary gland tumor with annual incidence of The histogenesis of salivary gland pleomorphic adenoma is still unclear.

One concept sustains the existence of an epithelial-mesenchymal transitions EMT process in pleomorphic adenomas by which neoplastic epithelial cells transdifferentiate into mesenchymal cells and leading to tissue heterogeneity from this salivary gland neoplasia. Here we investigate by immunohistochemistry the expression of growth differentiation factor 5 GDF5 and aggrecan in 15 cases of salivary gland pleomorphic adenomas.

We found that both markers were present in normal salivary gland, mainly in the cells that line striated and intercalated ducts suggesting their involvement in the morphogenesis of this duct system.

A constant positive reactivity for both markers was recorded in transition regions from tubular proliferative units to myxoid areas suggesting the involvement of an EMT process during the tumorigenesis of such salivary gland neoplasia.

Also, both markers may be implicated in the transdifferentiation of neoplastic myoepithelial cells from the myxoid zones to lacuna cells of adjacent chondroid areas completing the morphology of this salivary gland tumor. Morphometric and ultrasonographic study of the human fetal hip joint during intrauterine development Beata Baroti, Zsuzsanna Pap, Z. Panti, M. Buruian, Z. Pavai The main method for the early screening of the developmental dysplasia of the hip DDH is the ultrasound imaging.

There are several studies about the ultrasound imaging of newborns' hips, but only a few studies include the prenatal period of life.

Our aim was to examine the prenatal development of the hip joint through the evolution of the alpha angle seen on the ultrasound, described in the Graf R method, combined with anatomical dissection.

Materials and Methods: Thirty-one post-mortem fetal hips were analyzed trough anatomical dissection, in 25 cases trough ultrasound imaging, in which the alpha angle was measured. Based on the morphometric examination, we applied the sine rule and we calculated the alpha1 angle, which also represents the coverage of the femoral head.

Results: Based on the morphometric examination, not only the diameters of the femoral head and of the acetabulum, but also the joint cavity X showed an increase during development. Both of the alpha angles measured alpha, calculated alpha1 showed a decrease as the fetus developed.

Conclusions: The decrease of the angles alpha, alpha1 and the increase of the joint cavity during development correspond to the findings of the main research papers: the hip joint is less stable in the perinatal life. The alpha angle can be accurately determined only after the ossification of the acetabulum had started, in our case after the fetus is older than 18 weeks.

We hypothesized that folate receptor gene folr1 and others may be interacting to elicit neural tube defect NTDwhile N-acetylcysteine NAC may be beneficial for protection. In chicken embryo model, the experiment was conducted in two parts. The first part was carried out to test the optimum dose of VPA.

The second part was conducted to test the protective effect of NAC at doses 10 and 20 mM. VPA induced dysvascularization, incomplete somite enclosure, histone deacetylase HDAC inhibition, folate deficiency, homocysteine accumulation, SOD inhibition, glutathione depletion, elevated MDA and hydrogen peroxide. NAC alleviated most of these adverse effects. The microarray analysis revealed 17 genes downregulated and four upregulated.

VPA downregulated folr1 gene in a dose responsive manner without affecting pax-3 gene, which was ascribed to the metahypoxic state.

Five main groups were defined based on the histopathological criteria and then compared. The assessment of clinical data, in spite of a wide range of clinical expressions, revealed some particular features for each of the defined groups. The morphological data outlined also different behavioral profiles for each of the histopathological types of lung carcinoma.

These results showed that malignant epithelial tumors of the lung are still a major challenge from the detection until the therapeutic intervention and, therefore, the preoperative clinical-morphological investigation aggressive cancer of the lymph nodes crucial for a better adjustment of the therapeutic act according to the individual profile of each type of tumor. Testicular histopathological changes following sodium fluoride administration in mice Nicoleta Dimcevici Poesina, C.

Balalau, Maria Barca, I. Ion, Daniela Baconi, C. Baston, Violeta Baran Poesina It has been revealed that excessive fluoride intake on long-term is associated with toxic effects and can damage a variety of organs and tissues in the human body, including the male reproductive system. However, the molecular mechanisms of fluoride-induced male reproductive toxicity are not well understood.
