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.
Klebsiella pneumoniae has been found in the urinary tract of some bladder cancer patients. Bacterial presence within tumor tissue may affect the tumor-microenvironment and consequently influence cancer behavior, development, and treatment response. This study investigated mesenchymal and stemness transdifferentiation of bladder cancer cell line due to environmental stress of K. pneumoniae. Cultures of urothelial bladder cancer cell line (T24) were infected with K. pneumoniae with different multiplicity of infection (MOI) for two and four days. Transdifferentiation-associated features were morphologically assessed.
Moreover, transdifferentiation markers were estimated using Q-PCR and immunohistoc

The problem of missing data represents a major obstacle before researchers in the process of data analysis in different fields since , this problem is a recurrent one in all fields of study including social , medical , astronomical and clinical experiments .
The presence of such a problem within the data to be studied may influence negatively on the analysis and it may lead to misleading conclusions , together with the fact that these conclusions that result from a great bias caused by that problem in spite of the efficiency of wavelet methods but they are also affected by the missing of data , in addition to the impact of the problem of miss of accuracy estimation

The normal value of preptin in hypothyroidism (2638.4±280.0) in female while (2960.4±256.6) in male, in hyperthyroidism (589.0±90.1) in male, while in female (993.2±103.9), diabetes (2465.6±282.4) in female, in male (2085.5±282.8), in diabetes & hypothyroidism (3314.3±177.3) in male,(3179.4±265.7) in female, but control group in female (427.8±60.4), in male (384.7±62.4) at age (20-45) years they were divided into five groups: group one (G1) consisted of 30 hypothyroidism. The two group (G2) consisted of 30 patients with hyperthyroidism. And three group (G3) consisted of 30 healthy group, four group (G4) consisted of 30 patient with diabetes, and five group (G

Eighty-five male and female participated in this study, with mean age from 20-70 years. They included: negative control group of thirty euthyroid persons represented group 1, twenty-five hyperthyroid patient (positive control) included in the second group and thirty hyperthyroid patients treated with carbimazole drug for one year or less comprised the third group. By vein puncture, blood was collected, and serum was isolated and preserved at –20 C. Adipokines (interleukin-6 and vaspin) were estimated by using ELISA method. The results demonstrated that the the increase of IL-6 level was highly significant
... Show MoreReactive arthritis (ReA) has been as joint developing after infection, it belongs to spongylo arthritis (SpA). The etiology of this disease was multi factorial, the combination between genetic and environmental factors for triggering this disease. This study included 75 Iraqi Arab patients and 39 healthy control. Urine samples and blood were collected from each subject. The results showed that Escherichia coli bacteria (E. coli) was isolated from 32% of urine samples. HLA-B*27 allele frequencies was higher in ReA patients infected with E. coli. This lead to suggest that E. coli may be trigger factor in ReA patients with UTI which had HLA-B*27 positive.
Chronic renal failure (CRF) is progressive irreversible destruction of kidney tissue by disease which, if not treated by dialysis or transplant, will result in patient's death. This study was carried out on 30 patients (17 male and 13 female) with chronic renal failure. The aim of this research was studied the changes in the level of total protein ,albumin, calcium ,ionized calcium, phosphorous , iron ,ALP, LDH ,CK and FFA in patients with CRF before and after hemodialysis .The obtained results have been compared with 30 healthy subjects as control group (18male and 12 female).
