Pointing at Ito cell, from structure psa density md calc function or Cinderella story in liver histology Adriana Grigoras, Simona Eliza Giusca, Elena Roxana Avadanei, Cornelia Amalinei, Irina-Draga Caruntu For more than years, psa density md calc hepatic stellate cells also known as Ito cells have been the object of numerous studies that aimed at their characterization both in normal and postlesional status, where they play a key role in fibrosis progression specific for chronic hepatic pathology.
Converged studies on their histophysiology have revealed other functions, namely the involvement in liver embryological development and regeneration, metabolisms regulation, modulation of local inflammatory and immune reactions. Ito cells plasticity is surprising, as they are able to provide the connection between the complex sinusoidal and parenchymal microenvironment, influencing by autocrine and paracrine mechanisms the extracellular matrix content in tight correlation to growth and repair necessities.
Last but not least, Ito cells take an active part in systemic homeostasis maintenance by their capacity to store and mobilize vitamin A, respectively. The evolving interest in their research will be undoubtedly followed by a better knowledge of the physiopathological sequences responsible for liver diseases, as new targets for the development of new therapeutic approaches directed toward improvement of prognosis and patients quality of life. The utility of bone remodeling markers in the diagnosis, evolution and treatment response evaluation in bone metastases Mihail-Lazar Mioc, Horia George Haragus, Andrei Dan Balanescu, Pompiliu Horatiu Petrescu, Mihaela Iacob, Radu Prejbeanu After the lungs and liver, the bone is the third most common site for metastatic disease, appearing frequently in breast and prostate malignancies.

These pathological bone events that occur during the evolution of the metastatic disease are usually the onset of osteolysis and they lower the patient s life quality, and are sometimes the cause of death due to the required treatments surgery, radiotherapy. Due to the nature of the bone remodeling process, the markers that control bone resorption are the main early indicators of bone malignancy.
Analyzing these indicators in conjunction with traditional tumoral markers such as the prostate specific antigen PSA and the type I collagen cross-linked telopeptide ICTP can often increase the sensibility of the investigation and the chances of diagnosing bone metastases. The studies that were carried out in order to research this area of knowledge have had good and expected results.

Most of the efforts are now channeled into developing a better therapeutic strategy that would allow for the early diagnosis and treatment of the pathological bone events.
Until these markers can be used as standard investigation methods in all of our patients, some controlled studies must be carried out in order to statistically prove these results, which are purely observational. Narrow band imaging endoscopy for detection of precancerous lesions of upper gastrointestinal tract Dan Nicolae Florescu, Elena Tatiana Ivan, Adriana Mihaela Ciocalteu, Ioana Andreea Gheonea, Diana Rodica Tudorascu, Tudorel Ciurea, Dan Ionut Gheonea Gastric cancer GC is an important health problem despite the advances in surgery and chemotherapy and although the incidence is decreasing, GC is still considered the second most common cause of deceases produced by cancer.
Survival rates in gastric cancer are low, mainly because most patients are often diagnosed in late stages. The current interest in the diagnostic of GC is the prostatita de gradul i of early gastric cancer. Advances in high-resolution endoscopic techniques such as narrow band imaging NBI allow the detection of early precancerous lesions like polyps or metaplastic mucosa.
Performing only white light imaging endoscopy in order to detect gastric cancer can lead to omission or misdiagnose of a considerable number of early gastric cancers. NBI endoscopy associated with other high-resolution examinations is viable in detecting early gastric cancer, though few studies also indicate that the endoscopist s expertise plays an important factor as well.
Histopathological aspects in autoimmune cutaneous manifestations associated with hepatitis C virus infection Laura Statescu, Dan Vata, Delia Ciobanu, Laura Gheuca Solovastru, Maria Rotaru Autoimmunity is characterized by activation of the immune system that attacks and destroys wrongly, the body s own structures. All body tissues can be affected erythrocytes, leukocytes, platelets, blood vessels, muscle tissue, endocrine system, and otherincluding the skin.
Autoimmune diseases psa density md calc an increased frequency in women, especially in adulthood, and they are associated with hereditary factors. Although the etiology of autoimmune diseases is incompletely elucidated, there is an association between chronic infection with hepatitis C and autoimmunity, association highlighted and well documented in clinical studies.

Other viral infections do not have the same connotation in the context of autoimmunity, but it is recognized that they are an important triggering factor in the pathophysiological mechanism. The cases associating chronic hepatitis C treated with interferon and ribavirin, with multiple autoimmune diseases substrate, raising the discussion of a possible pathophysiological correlation between them. In the last 40 years, there was observed a rapid increase of their incidence, because of the UV radiations exposure and weather changes.
Although its morbidity is a relatively modest one, the direct social costs of NMSCs are quite substantial due to a high incidence. Due to these reasons, numerous studies try to clarify the etiopathogenic mechanisms of NMSCs, to elaborate treatment and prevention measures.
In the last years, a special attention was given to the relation between inflammation and skin cancer.
Psa density md calc our study, we performed a histological and immunohistological evaluation of the inflammatory reaction on a number of 73 surgical exeresis pieces coming from the patients diagnosed with NMSCs. The peritumoral inflammatory reaction in NMSCs was an extremely variable one in intensity and distribution, from one case to another and even from one area to another within the same tumor, thus proving the complexity of the relations between tumor cells and the cells of the immune system.
By comparing the intensity of the inflammatory reaction between the two main types of NMSCs, there was observed that in SCCs the inflammatory reaction was more intense in comparison to BCCs. Also, in SCC there was highlighted a more abundant inflammatory infiltrate in poorly differentiated psa density md calc, in comparison to the well-differentiated ones.
The presence of the immune system cells T-lymphocytes, macrophages, mast cells among the tumoral cells, in a direct contact with these, makes us believe that between the two categories of cells there may appear mechanisms of intercellular communication, distinct from the mechanisms of paracrine signaling.
Caspase 3 expression and plasma level of Fas ligand as apoptosis biomarkers in inflammatory endotoxemic lung injury Raluca-Stefania Fodor, Anca-Meda Georgescu, Bianca-Liana Grigorescu, Adrian-Dan Cioc, Mihaly Veres, Ovidiu-Simion Cotoi, Pal Psa density md calc, Sanda-Maria Copotoiu, Leonard Azamfirei Objective: The objective of this study is to evaluate if the immunohistochemical expression of a pulmonary apoptosis marker and plasma level of Fas psa density md calc FasL correlates with the dose- and time-dependent severity psa density md calc lung injury, induced by the administration of lipo-polysaccharide LPS in an endotoxemic rat model.
We measured FasL plasma levels of the rats at different time points and analyzed îmbunătățește urinarea cu prostatita relationships with markers of lung injury. To investigate the level of caspase 3-protein expression, the immunohistochemistry of the lung tissue was assessed.
