Overexpression of HER-2\neu receptor protein in Urinary Bladder Carcinoma, An Immunohistochemical Study.
...Show More Authors

Background: Bladder carcinoma is one of the most common cancer worldwide, it accounts for 6.5% of all cancers, with highest incidence in industrialized countries .It represents the fourth most common cancer in men and the eighth in women. Bladder carcinoma depends in its pathogenesis on a combination of genetic and environmental factors, these factors produce phenotypic changes that allow normal transitional cells to become cancerous and finally acquire the “malignant phenotype".  Many attempts had been tried to explore the role of some genetic abnormalities encountered in bladder carcinoma. It has indicated that many genetic abnormalities may underline the pathogenesis of cancer evolution of urinary bladder like VEGF , P53, Bcl2 and RB, but nowadays a scientific efforts have raised the possible role of Her-2/neu in bladder carcinoma, and the rate of its overexpression in bladder carcinoma is ranging from 2% - 74%. 
Objective: To estimate immunohistochemical expression of HER-2\neu receptor protein in Urinary Bladder Carcinoma in relation to other parameters; sex grade, pattern of tumor and stage of tumor .
Methods: The present work is performed in the Department of Pathology and Forensic medicine, College of Medicine, Kufa University. Formalin fixed, Paraffin-embedded blocks from 60 (43 males and 17 females) patients with urinary bladder carcinoma were included in this study. A group of 12 patients with chronic cystitis were included as a control group. Avidin-Biotin Complex method was employed for immunohistochemical detection of HER-2\neu.
Results: HER-2\neu overexpression was positive in 41.6% of urinary bladder carcinoma, while there was no expression in benign bladder tissue (P<0.05). HER-2\neu immunohistochemical staining was positively correlated with, grade and stage of urinary bladder carcinoma (P<0.05).
Conclusion: These findings support the role of HER-2\neu in the carcinogenesis of urinary bladder carcinoma regarding behavior, and aggressiveness, and thus HER-2\neu could be considered as a poor prognostic parameter in urinary bladder carcinoma.

Zinc Chloride Can Mitigate the Alterations in Metallothionein and Some Apoptotic Proteins Induced by Cadmium Chloride in Mice Hepatocytes: A Histological and Immunohistochemical Study
...Show More Authors

The heavy metal cadmium is extremely harmful to both humans and animals. Zinc supplementation protects the biological system and reduces cadmium-induced toxicity. This study aimed to determine whether zinc chloride (ZnCl2) could protect male mice with the damaged liver induced by cadmium chloride (CdCl2). The protective role of zinc chloride and expression of the metallothionein (MT), Ki-67, and Bcl-2 apoptotic proteins in hepatocytes were studied after subchronic exposure of mice to cadmium chloride for 21 days. Thirty male mice were randomly categorized into 6 groups (5 mice/group) as follows: a control group that did not receive any treatment, a group given ZnCl2 at 10 mg/kg alone, and two groups received ZnCl2 (10 mg/kg) i

Detection of Human papillomavirus in surface epithelial ovarian carcinoma using in situ hybridization technique
...Show More Authors

Background: The role of Human papillomaviruses (HPV) in the etiology of ovarian cancer remains unclear and the results are controversial. Several studies have verified the presence of HPV DNA in both malignant and benign ovarian tumors.
Objectives: Determine the percentage of detection of HPV high (16&18) and low risk types (6&11) in surface epithelial ovarian carcinoma compared to benign and control groups.
Materials And Methods: Molecular detection and genotyping of HPV DNA were performed in 76 ovarian tissue blocks by using in situ hybridization (ISH) technique for detecting and localization of high risk HPV (16 and 18) and low risk HPV (6&11) types.
Results: The presence of ISH signals fo

Plasmid Role in Crystals Protein Production in Locally Isolated Bacillus Thuringiensis
...Show More Authors

The ability of crystals protein production was studied in local isolate Bacillus
thuringiensis by microscope examination, and the crystals protein production were seen
after 48 hour from growth starting, the study of plasmid profile of the isolate using gel
electrophoresis technique in 0.7% of agaros gel, revealed that it had one Mega plasmid
band, the plasmid role in production of crystals protein was studied by using conjugation experiments, that they applied on the local isolate B. thuringiensis which was crystals
protein producer and Rifamycin sensitive as donor cells, with Bacillus spp. which didn’t
produce crystals protein and Rifamycin resistance as recipient cells. Conjugation
experiments assured the transm

Large functioning Childhood adrenocortical carcinoma (Case report)
...Show More Authors

We describe a large functioning non metastasizing ACC in 8 years old boy who presented with a history of precocious puberty noticed by his parents since 3 months .Ultrasound of the abdomen showed a large well defined right suprarenal mass with calcification and necrosis . MRI  showed  the mass to be hypojntense to liver on T1 and   hyperintense  to liver on T2, and  dynamic CT scan revealed a large hetrogenous  enhancing right suprarenal mass with calcification and necrosis , clear chest .Histopathology done after surgical removal reveal adrenocortical carcinoma,so we recommend to do an abdominal ultrasound to any child with precocious puberty because it is easy,cheap and non invasive , if any suprarena

Impact of Plasma Focal Adhesion Kinase, Ephrin Receptor Type A4, and Adiponectin in Patients with Acute Myeloid Leukemia
...Show More Authors
Abstract<sec> <title>BACKGROUND:

Focal adhesion kinase (FAK), ephrin receptor type A4 (EphA4), and adiponectin (ADPN) are important indicators in inflammation, tumor growth, migration, and angiogenesis in some cancers. The predictive impact of their concentrations in acute myeloid leukemia (AML) patients to be identified remains. The research sought to explore the effect of FAK, EphA4, and ADPN as prognostic biomarkers, and their influence on patient survival, and to look for any potential correlation between their levels with hematological parameters in AML patients.

...Show More Authors

Background: Steroid-resistant nephrotic syndrome (SRNS)is associated with serious complications and financial burdens. Studies reported increased urinary neutrophil gelatinase-associated lipocalin (uNGAL) levels in children with idiopathic nephrotic syndrome (INS).

Objectives: This study aimed to evaluate the uNGAL potential to distinguish SRNS from steroid-sensitive nephrotic syndrome (SSNS) in Iraqi children.

Patients and Methods: Children with SRNS (n=31) and SSNS (n=32) were recruited from Babylon Hospital for Maternity and Pediatrics from March to June 2022. Patients' data included demographics, clinical characteristics, and urinary lab tests. The uNGAL concentrations

Immunohistochemical expression of p53 and PCNA proteins in oral lichen planus and oral dysplasia
...Show More Authors

Background: Oral lichen planus (OLP) is a relatively common chronic inflammatory muco-cutaneous disease classified among the potentially malignant lesions of oral mucosa. The aim of this study is to investigate and compare the expression of p53 and PCNA proteins in oral lichen planus and epithelial dysplasia cases. Materials and methods:Formalin-fixed and paraffin- embedded blocks of 21 lichen planusand 21 oral dysplasia cases were referred to immunohistochemical (IHC) analysis for anti p53 and anti PCNA monoclonal antibodies. Results: The results showed that positive nuclear staining for p53 was found in 11/21 (52.4%) cases of lichen planus and 17/21 (80.9%) cases of dysplasia. Positivity for PCNA was observed in 18/21(85.7%) of oral li
