Back ground: Epstein- Barr virus (EBV) is a ubiquitous in that infecting more than 90% of adult population worldwide. Recently, EBV has been linked to the development of variety of human malignancies. P53 gene is mutated in more than 50% of human cancers. Cell cycle dysregulation, measured by p53 protein expression, and latent EBV infection are important in the pathogenesis of Non-Hodgkin’s lymphomas.
Objective: To analyze the distribution and impact of concordant p53 expression and latent EBV infection on a group of B & T cell types of NHL.
Materials and Methods: Forty (40) formalin-fixed, paraffin embedded tissue blocks were obtained from lymph nodes biopsies related to patients with NHL.
In addition, biopsies of twenty (20) lymph nodes autopsies were included as apparently normal control group. The clinico- pathological criteria of NHL cases were assessed and In Situ Hybridization( ISH ) techniques for mutant p53 and Epstein-Barr Early Repeats(EBERs) detection were performed.
Results: The percentage of EBV-ISH reaction results in the total group of NHL was (60%), where its percentage in NHL, B-cell type was (58.6%)and in NHL, T-cell type (63.7%). None of the control group showed EBV-ISH reaction. Statistical analysis showed significant difference between these groups (p<0.05). The percentage of B-cell lymphoma with moderate signal score for EBV-ISH test was (41.4%) while with strong scoring was (17.2%). In the T-cell lymphoma, moderate signal scoring was (18.2%) while strong scoring was(45.5%). Statistically, they showed no significant differences (p> 0.05). Mutant p53 gene was observed in 60% of NHLs and dual positivity of EBV and p53-ISH was found in 42.5 % of cases. Regarding the grades, it was found that the higher level of p53 expression was observed in low grade tumors (39.3% ; 11out of 28) NHL.
Conclusion: The present findings indicate that cell cycle dysregulation and EBV-related transformation are important in the pathogenesis of NHL.
Background : The aim of this work is to study the clinical features and causative fungi of tinea pedis in diabetic and non-diabetic patients. Result : Tinea pedis was estimated to be the second most common skin disease in the United States, after acne. Up to 15% of the U.S., population may have tinea pedis. Across Europe and East Asia, prevalence rates reach 20 %. Methods: The Complete history taking regarding: age, sex, occupation, residency, history of diabetes and diabetic profile (fasting blood sugar and post prandial).and Clinical examination of the feet Aim of the study : The aim of this work was to study the clinical features and causative fungi of tinea pedis in diabetic and non-diabetic patients Conclusion : Tinea pedis is more

To find estimated values for these two scale parameters using real data for COVID-19 which was taken from the Iraqi Ministry of Health and Environment, AL-Karkh General Hospital. Then the Chi-square test was utilized to determine if the sample (data) corresponded with the Exponential-Rayleigh distribution (ER). Employing the nonlinear membership function (s-function) to find fuzzy numbers for these parameters estimators. Then utilizing the ranking function transforms the fuzzy numbers into crisp numbers. Finally, using mean square error (MSE) to compare the outcomes of the survival
... Show MoreFusidic acid (FA) is a well-known pharmaceutical antibiotic used to treat dermal infections. This experiment aimed for developing a standardized HPLC protocol to determine the accurate concentration of fusidic acid in both non-ionic and cationic nano-emulsion based gels. For this purpose, a simple, precise, accurate approach was developed. A column with reversed-phase C18 (250 mm x 4.6 mm ID x 5 m) was utilized for the separation process. The main constituents of the HPLC mobile phase were composed of water: acetonitrile (1: 4); adjusted at pH 3.3. The flow rate was 1.0 mL/minute. The optimized wavelength was selected at 235 nm. This approach achieved strong linearity for alcoholic solutions of FA when loaded at a serial concentrati

Materials and methods: for reliable evaluation, more time-efficient and user friendly method we used simple computer program with image analysis options as independent parameters for reading positive results. To test the validity of visually scored results, we compare and correlate the results of Digital image analysis (DIA) variables with the visual scores of 280 pictures taken from entire stained glioma tumor sections for Bcl-2 and P53 oncoproteins in different glioma tumor grades.
Results: In this study, rates expression of both oncoproteins was evaluated visually in glioma tumor samples (
Background: There is a recognized association between prolongation of the heart rate corrected QT interval (QTc) and antipsychotic drugs. QTc prolongation may increase the risk of ventricular tachyarrhythmias, especially torsade de pointes, and therefore, sudden cardiac death.
Objective: This study assess the effect of antipsychotics and prolongation of the heart rate corrected QT interval (QTC), and QTC prolongation may increase the risk of ventricular tachyarrhythmias, especially torsade de pointes and sudden cardiac death.
Results: Abnormal QTc was defined as an interval of more than 440 ms (0.44 second) and was present in 21.7% (43 patients of 198). Benzhexol (-0.333

Show MoreBackground: Malignant lymphoma is a term that describes primary tumors of the lymphoreticular system, almost all of which arise from lymphocytes.MMP-1 is the most ubiquitously expressed interstitial collagenase, a subfamily of MMPs that cleaves stromal collagens. It is also called collagenase-1.TIMPs which inhibits MMP activity and thereby restrict extracellular matrix breakdown, TIMP-1 is a stromal factor that has a wide spectrum of functions in different tissues. Material and Methods: This study was performed on (68) formalin-fixed, paraffin-embedded blocks, histopathologically diagnosed as lymphoma (head and neck lesions). Immunohistochemical staining of MMP1and TIMP1 was performed on each case of the study sample. Results: The expressio
