Immunohistochemical expression of beta-catenin in ampullary adenocarcinoma: a cross-sectional retrospective study
...Show More Authors
Introduction:

Ampullary carcinomas are uncommon malignant tumours of the digestive system, they usually are adenocarcinomas presenting histologically as three types: intestinal, pancreaticobiliary and mixed. β-catenin is a multifunctional protein involved in physiological homoeostasis and intracellular adhesion. Abnormal nuclear accumulation of β-catenin has been described in many malignancies such as colon, breast, liver and others. The relationships between the immunohistochemical expression of β-catenin and the subtype, the grade and the stage of ampullary carcinoma are studied.

Material and methods:

A cross-sectional retrospective study was done on 25 formalin-fixed paraffin-embedded blocks of ampullary carcinoma: Cases were collected from the archives of the pathology department in the Gastroenterology and hepatology teaching hospital, medical city/ Baghdad from January 2019 to March 2022. The data of the patients and the characteristics of the tumour were derived from the pathological reports; additional sections from the block were stained with β-catenin immunohistochemically.

Results:

25 paraffin blocks from patients with ampullary carcinoma (12 males, 13 females) were included in the study. 64% of the cases are classified as pancreaticobiliary, 20% as mixed, 12% as intestinal and 4% as adenosquamous type. Eighty-four percent of the cases are moderately differentiated, and the remaining is poorly differentiated. Most cases show strong β-catenin membranous staining and 80% express 3+ staining of cytoplasmic β-catenin. Regarding nuclear β-catenin staining, 56% has negative staining.

Conclusion:

No significant association was found between the cytoplasmic and the nuclear expression of β-catenin and the tumour type, size and lymph node status. The grade of the tumour showed a significant correlation with the cytoplasmic expression; while, no correlation was noted with the nuclear expression. This study results do not support the use of beta-catenin as a diagnostic marker or prognostic marker in ampullary cancers.

ABSTRACTBackground: In Iraq smoking is a common habit in both the urban and rural areas. There are many respiratory diseases like chronic bronchitis, bronchial carcinoma and emphysema which are related to chronic tobacco smoking.Objectives: To study the effect of tobacco smoking on the respiratory system, to establish a correlation between chronic tobacco smoking and its effects on the parameters which were studied and to create awareness in tobacco smokers about the effects of tobacco on their healthMethod: In this study 100 male subjects, 50 chronic smokers and 50 non- smokers were assessed for their pulmonary function tests by using a computerized spirometer.Results: Almost all their respiratory parameters were significantly reduced.

A Comparative Study of Organic and Mineral Acids in the Release of Potassium from Potassium Feldspar Minerals
...Show More Authors
Abstract<p>A study conducted a laboratory experiment to measure the release of potassium and the dissolution of feldspar minerals in soils from different locations in Karbala Province (Ain Al-tamur, Qasr Al-Akhyar, Fadak Farm). The study involved the addition of organic acids (fulvic and humic) and mineral acids (sulfuric and phosphoric) at concentrations of 5% and 10% to sand-separated soil samples obtained through wet sieving. Feldspar minerals were identified using a polarized light microscope, and the percentage of each type of feldspar mineral was calculated. The results demonstrated that organic acids outperformed mineral acids in releasing potassium at both concentrations. Among the organ</p> ... Show More

A study of adsorption in aqueous solution of p,o,m-Chlorophenol on Iraqi siliceouns rocks powder
...Show More Authors

Adsorption of Chlorophenol compounds in aqueous solution on Iraqi siliceouns rocks powder have been investigated. UV technique has been used to determine the adsorption isotherms. The results showed that the adsorption isotherms obeyed Freundlich adsorption equation. The adsorption was endothermic process, increasing temperature leads to increasing adsorption.  H,  S,  G were calculated. The results showed that the adsorption increases with increasing acidity of solutions
