Intraductal papilloma ck5 6
The nucleocrine pathway comes of age Razvan T. Radulescu More than 20 years ago, it was initially predicted that hormones cancer colon gpc growth factors might promote cell growth by binding and thereby inactivating tumor suppressors, as exemplified by the proposed complex formation between insulin and retinoblastoma protein RB.
Meanwhile, additional nucleocrine pairs have emerged through further experimental studies, specifically the FGF1-p53 and angiogenin-p53 heterodimers. Moreover, first experimental clues have been obtained as to the intranuclear presence of the previously surmised heterodimer between the EGF precursor and the p tumor suppressor.
Intraductal papilloma ck5 6 papilloma ck5 6 findings point to intraductal papilloma ck5 6 more general significance of the nucleocrine pathway in cell growth regulation and as a particularly useful target in cancer therapy. Carbon nanotubes for cancer therapy and neurodegenerative diseases Elena Daniela Melita, Gabriela Purcel, Alexandru Mihai Grumezescu Our review summarizes the latest approaches regarding a new class of nanomaterials - carbon nanotubes CNTs - which are promising candidates in different intraductal papilloma ck5 6 of nanomedicine.
This paper discusses the main applications of CNTs in the repair of injured nerves and also as simptome ale condiloamelor uretrale systems for cancer therapy in difficult to reach anatomic sites. In terms of neurological applications, we focus on neural interface, neural stimulation, microelectrodes, and differentiation of stem cell into neural cells.
Also, we highlight the in vitro and in vivo applications of CNTs-mediated cancer therapy and we will explain why CNTs are used for the treatment of difficult tumors.

The obtained data demonstrate that HMNPs can be used as an efficient drug delivery system, for clinically relevant antimicrobial drugs. HMNPs antimicrobial activity depended on the loaded drug structure and the tested microbial strain, being more efficient against Pseudomonas aeruginosa, comparing with the Escherichia coli strain.
The novel HMNPs demonstrated an acceptable biocompatibility level, being thus a very good candidate for biomedical applications, such as drug delivery or targeting.

Ultrastructure of the human palatine tonsil and its functional significance Marko Jovic, Verica Avramovic, Predrag Vlahovic, Vojin Savic, Aleksandra Velickov, Vladimir Petrovic The human palatine tonsils represent a mucosa-associated lymphoid tissue with a significant function in mucosal protection against alimentary and airborne pathogens.
The ultrastructure of different morphological compartments in the human palatine tonsil was studied in eighteen tonsils obtained from the patients who had undergone elective tonsillectomy due to chronic tonsillitis.
The tonsillar specimens were analyzed by scanning and transmission electron microscopy. The results showed the presence of tight junctions between superficial epithelial cells of the oropharyngeal tonsillar surface. Antigen-presenting Langerhans cells with typical intracytoplasmic Birbeck granules were also found in the crypt epithelium.
The lymphoid follicles are composed of lymphocytes and two types of non-lymphoid follicular cells: small fibroblast-like cells and large cells, morphologically consistent with antigen-bearing follicular dendritic cells or macrophages. The interfollicular areas consisted of a dense network of reticular cells and reticular fibers; many lymphocytes were interspersed between the reticular fibers.
In addition to arterioles and high endothelial venules in the interfollicular lymphoid tissue, some fenestrated capillaries were seen intraepithelially and subepithelially.
The complex ultrastructure of the human palatine tonsil provides a microenvironment necessary for antigen uptake, antigen processing and immune response.

BRCA1 insC founder mutation has not a significative recurrent presence in Northeastern Romanian cancer patients Lucian Negura, Cristian Petru Dusa, Miruna Ioana Balmus, Doina Azoicai, Anca Mihaela Negura, Mihai Vasile Marinca, Lucian Miron Developed two decades ago, oncogenetic medical practice mainly concern breast, ovarian and colorectal intraductal papilloma ck5 6, and is targeting the hereditary risk factor, the only one that shows positive predictive value justifying the molecular diagnosis.
The gold standard for molecular diagnosis is Sanger sequencing of all exons and exon-intron boundaries, which is expensive and time consuming. More than BRCA sequence variants are reported in international databases, but in some populations or ethnic groups a few founder mutations showed to have a recurrent presence.
This may be very useful in establishing a combined technical approach for mutation detection, including rapid and cheap pre-screening methods for most common mutations. Here we present a complete screening of consecutive series of breast and ovarian cancer patients for the presence of BRCA1 insC. The presence of the mutation was investigated by allele specific multiplex-PCR on genomic DNA extracted from peripheral blood. No mutation carrier was identified among breast or ovarian cancer patients.
Our findings intraductal papilloma ck5 6 that BRCA1 insC may not have a strong recurrent effect in Romanian population comparing to neighboring countries. This may be particularly useful in establishing further pre-screening strategies. The study group consisted of 61 individuals with MS and the control group of 73 individuals without MS, matched for age ajutor pentru viermi de ou gender.
For each individual, clinical and genetic parameters with possible influence on PON1 activities paraoxonase, arylesterase and lactonase were measured. PON1 activities were influenced by all three polymorphisms, regardless of the presence of MS. Sonographic evaluation of fetal cerebral structures correlated with histological aspects Alexandru Cristian Comanescu, Nicolae Cernea, Oana-Sorina Tica, Maria Victoria Comanescu, Elena Carmen Niculescu, Charoula Florou, Florin Grosu Prenatal development of the human brain from undifferentiated neuroepithelium, crosses numerous steps towards primordial organization and subsequent cytoarchitectural layering, ascending and progressive from the lower cortical layers to the superior ones.
Our study represents a systematic, comparative assessment of imaging studies and the histological evaluation of the prenatal development of the human brain. We evaluated cases using 3D ultrasound. Histological study was performed on 17 cases aged between 8 and 32 weeks pregnancy and compared with imaging results.
For the ultrasound study, we chose five anatomical landmarks: the choroid plexus, thalamus, cerebellum, hippocampus and island Sylvian fissure. The histological study was performed on dissected brain specimens preserved in formaldehyde and was followed by immunohistochemical determination in order to complete the picture of the morphological evolution of the structures evaluated.
We analyzed the accuracy of the description of marker elements choroid plexus, thalamus, cerebellum, hippocampus and Sylvian fissure in three-dimensional ultrasound evaluation. This showed a good correlation with the morphological evaluation as well as with the dimensional descriptions from the literature. Histological and immunohistochemical assessment helped complete the picture of the central nervous system development.
Highlighting fetal cerebral structures by intraductal papilloma ck5 6 ultrasound, together with morphological examination helped us create a dynamic array of the central nervous system development. Prognostic markers in the pathology of cardiac failure: echocardiography and autonomic nervous system dysfunction Elena Cristina Enciu, Silviu Marcel Stanciu, Dumitru Matei, Adrian Costache Introduction: Chronic heart failure is a major health problem worldwide and despite the therapeutic advances, the mortality and morbidity still remain high.
Echocardiography is the gold standard for left ventricular function assessment and may provide prognostic information for predicting future heart failure events.

Patients and Methods: We analyzed the main echocardiographic markers used for the prognostic of chronic heart failure patients such as the ejection fraction, diastolic impairment and the collapse of inferior vena cava. Also, another parameter is studied, recently recognized as a marker for future cardiac events: autonomic nervous dysfunction. The current paper makes a comprehensive approach of the echocardiographic markers recommended for human papillomavirus mouth treatment diagnosis and follow-up of heart failure adapted to what we really find intraductal papilloma ck5 6 our everyday practice with a correct patient management in a clinical and biological context.
Even though left ventricle ejection fraction is the most often used parameter for cardiac failure follow-up and prognostic, new and more accurate parameters should be used: Tissue Doppler Imaging and Heart rate recovery - which may become a therapeutic target in the era of cardiac rehabilitation.
Conclusions: There is no stand-alone marker for the assessment of cardiac failure; each of the parameters presented has its advantages and its pitfalls. Parazitii quotes allows a morphologic study, which should always be correlated with clinical and functional studies exercise stress test and autonomic nervous system dysfunction.
Progressing as a chronic inflammation at the level of tooth support tissues, untreated chronic periodontitis may lead to a premature loss of the dental organ. Even though the main lesions caused by the periodontal disease affect the alveolo-dental ligaments, we tried to highlight the presence of certain lesions of radicular dentine in patients with chronic marginal periodontopathy.
In our study, in the patients with chronic marginal periodontopathy, at periodontium level, there was highlighted the presence of a chronic inflammatory process with numerous lymphocytes and macrophages, microhemorrhages, and also areas with tissular necrosis.
At radicular dentine level, in the cases of old, untreated periodontal disease, there were observed areas of more or less extended demineralization, erosion and necrosis.
Our study showed that chronic periodontal disease may affect the tooth, as well, not only its support tissues. Proximal tibial osteosarcoma in young patients: early diagnosis, modular reconstruction Razvan Ene, Ruxandra Diana Sinescu, Patricia Ene, Dan Popescu, Monica Mihaela Cirstoiu, Florin Catalin Cirstoiu Osteosarcoma is the most common bone tumor that occurs in children and young adults with prevalence of teenage.
There can be identified many subtypes of osteosarcoma by how they look on X-rays and under the microscope. Osteosarcoma can be classified as high-grade, intermediate grade, or low-grade. This has a significant prognostic value of tumor development suggesting the growth rate and the potential for expansion.
Betweenin the Department of Orthopedics and Traumatology, University Emergency Hospital of Intraductal papilloma ck5 6, Romania, were treated seven cases of osteosarcoma of the proximal third of the tibia in young, early-diagnosed cases without metastasis.
The treatment involved resection of tumor formation and reconstruction with a modular prosthesis. Postoperative patients were mobilized for a week without charging the operated limb under the protection of orthesis.
During this period continued active and passive mobilization of the ankle and foot to prevent stiffness and to reduce postoperative swelling. From the second postoperative week, patients are mobilizing with progressive charging but not being allowed to do any flexion in order to protect de insertion of medial gastrocnemius muscle rotation flap used to cover the prosthesis and to protect the patellar tendon reinsertion.
Intraductal papilloma ck5 6 extensive surgery does not improve survival rate of these patients compared to treatment by amputation of this pathology but greatly increases the comfort of life and in all cases ensure socio-professional reintegration of these patients. To ensure optimal postoperative results perform a complete diagnosis and preoperative oncological treatment before surgery, if applicable.
One of the best known markers is CD34, a surface antigen. The most used immunohistochemical marker for identification of activated endothelial cells is CD We chose to compare these two markers in order to evaluate angiogenesis of the rectal cancers by determining the microvessel density MVD.
Our study intraductal papilloma ck5 6 31 patients with rectal cancer betweenwho underwent rectal resection at Arad and Timisoara Counties Hospitals, Romania. We used MVD quantification by highlighting the tumor blood vessels with two different endothelial markers using the immunohistochemical protocols.
The evaluation of both CDCD showed the role of angiogenesis in the cancer proliferation and local spread, the angiogenesis level being maintained high even in the advanced stages of the disease. There was observed a difference between the intratumoral and peritumoral MVD, the study of this difference possibly leading to a better assessment of prognosis and adjusted therapies in the future. Immunohistochemical aspects of apoptosis in gingival mucosa with papilloma and condyloma acuminata Monica Scrieciu, Veronica Mercut, Razvan Mercut, Marina Olimpia Amarascu, Sanda Mihaela Popescu, Anca Mihaela Predescu, Ileana Monica Banita The oral mucosa is intraductal papilloma ck5 6 component of the oral ecosystem, which can be aggressed by corrosion products released from the dental alloys used in prosthetic dentistry therapy.
The purpose of this study was to compare the in vivo effect of nickel and copper compounds on the oral mucosa cells, including their ability to induce cell death, by analyzing the cytochrome c cyt. Gingival mucosa fragments obtained from the subjects with dentures manufactured by nickel or copper casting alloys were processed through the histological technique of paraffin inclusion.

The sections obtained were stained by usually histological methods in order to highlight the histopathological lesions and also analyzed using the immunohistochemical technique in order to study the cyt. The papillomatosis lesions were observed in the gingival mucosa fragments obtained from the subjects with nickel-based alloy dentures and the condyloma intraductal papilloma ck5 6 lesions were observed in those obtained from the subjects with copper-based alloy dentures.
The cyt. We can conclude that the two types of metal alloys have different effects on the adjacent gingival mucosa. The results of this study are indicating that the interaction between the HeLa cells and S. The pre-treatment of HeLa monolayer with inactivated bacterial cells 24 hours before the viral infection is increasing the expression level of TNF-alpha, IL-6 and IL-8 pro-inflammatory cytokines genes, also suggesting that bacterial antigens could contribute to the decrease of viral multiplication rate.
The current antiviral therapy allows the virus eradication or the permanent inhibition of the virus replication sustained virological response, SVRthe reduction of the inflammation, and the prevention or the reduction of liver fibrogenesis histological response. We studied the histopathological aspects found during percutaneous liver biopsy in patients with chronic hepatitis C viral infection who were treated and monitored over intraductal papilloma ck5 6 period of two years.
The assessment of the histological activity index through Ishak score determined the presence of: mild chronic hepatitis in 12 The percutaneous liver biopsy performed on the patients with chronic viral hepatitis C intraductal papilloma ck5 6 a series of histological alterations, the most frequent being: portal inflammation, periportal necrosis, lobular inflammation, focal necrosis, and hepatic fibrosis scarring.
The severity degree of this histopathological aspect was correlated with the hepatitis activity index. The association of piecemeal with bridging necrosis is the deadline at which the antiviral treatment can still be effective. Evidence of early fibrosis represent the important moment for the antiviral treatment start.
The specific histopathological aspects, but not pathognomonic, of chronic hepatitis C hepatic steatosis, portal lymphoid infiltrates and bile duct damage had a reduced incidence, occurring in only half hepatic steatosisa quarter viermi încrucișați roșii lymphoid infiltrates and a fifth destruction of biliary ducts of all the patients with chronic viral hepatitis C, and these patterns was correlated with advanced degree of necroinflammatory process of the liver, particularly in intraductal papilloma ck5 6 portal tracts.
Fenugreek powder exerts protective effects on alcoholised rats kidney, highlighted using ultrastructural studies George Ciprian Pribac, Mircea Florin Sferdian, Carmen Neamtu, Constantin Craciun, Corina Luminita Rosioru, Aurel Ardelean, Bogdan Dan Totolici Trigonella foenum-graecum TFG seeds exert a protective antioxidant effect and membrane protector through their rich content in polyphenolic flavonoids. The previous research focused on the hypoglycemic action of the seeds, with scarce studies on the preventive effects in the pathology of the kidney.
Our work was conducted on an experimental in vivo model; the animals were given two different concentrations of TFG seeds, consequently to alcohol intoxication.

Transmission electron microscopy TEM analysis showed vacuolation in cytoplasm, edemas at the apical pole of the nephrocytes, diffusion of the cytoplasmic and mitochondrial matrix and the increase in number of the lysozymes and especially peroxisomes, as well as the congestion of blood capillaries. In the case of the groups T5R and T10R, which received Trigonella powder together with ethanol, the structural and ultrastructural changes produced by the ethylic intoxication were more reduced, being somewhat improved in the T5R group.
Therefore, the majority of the cells nuclei have retained their spherical shape, being at the same time predominantly euchromatic, with little heterochromatin and evenly dispersed. Our results suggest the use of Trigonella seeds as a food supplement to prevent cellular deterioration and improve renal morphology and function. Considerations on morphological abnormalities of permanent teeth in children with cleft lip and palate Anca Maria Raducanu, Andreea Cristiana Didilescu, Ion-Victor Feraru, Mihaela Adina Dumitrache, Tudor Alexandru Hantoiu, Ecaterina Ionescu Oral clefts are commonly associated with dental anomalies of number, size, shape, structure, position and eruption affecting both dentitions.
Dental malformations may affect the development, growth and functions of the dento-maxillary apparatus chewing, aesthetics, speech. The study sample included 48 patients with various types of CLP 15 girls and 33 boys aged between The control group without CLP consisted of patients girls and boys. The proportion of patients with dental shape anomalies in the control group was 8. We selected a group of 32 subjects 22 cases intraductal papilloma ck5 6 10 controls for studying the TNFA polymorphism and 97 subjects 66 cases and 31 controls for IL-1A polymorphism.
