Introduction: The insertion/deletion (I/D) polymorphism of 287 bp Alu repeat sequence in intron 16 of Angiotensin Converting Enzyme (ACE) gene resulting in three genotypes I/D, D/D and I/I. ACE gene expression is associated with ACE levels in cells and in the plasma. It indicated that the polymorphism may modulate the expression of the ACE gene. The D/D genotype is believed to confer deleterious effect to many pathogenesis, also, it might be a cause-effect for type 2 diabetic nephropathy (T2DN). In this study, we evaluated the frequency of the different genotypes of ACE gene and investigated if there is an association between ACE gene polymorphism and T2DN by comparing the genotypes results of T2DN patients to healthy control, Type 2 diabetes mellitus (T2DM) and nephropathy patients in Gaza Strip. Methodology: The study included 170 subjects, consisting of 43 T2DM patients undergoing dialysis "T2DN" compared to 41 T2DM patients who were not undergoing dialysis, 43 patients undergoing dialysis without T2DM and 43 healthy individuals. Blood samples were collected in EDTA tubes for DNA extraction. Polymerase Chain Reaction (PCR) was used to detect ACE gene polymorphism. All subjects were asked to fill the questionnaire interview. Results and Conclusion: The initial results showed that there is no statistically significant association between ACE genotypes and T2DN, also between the T2DM and nephropathy when compared to the healthy control (p> 0.05). The (D/D) genotype was the most frequent in all study groups. Moreover, no association was observed between ACE genotypes and gender, diabetic nephropathy, nephropathy, diabetes, hypertension, obesity and various other diabetes complications.

Hemodialysis (HD) is a process in which the blood passes through a machine (dialyzer) to remove waste. Angiotensin Converting Enzyme (ACE) is one of the major components of the renin-angiotensin aldosterone system (RAAS) that is responsible for blood pressure regulation. Insertion/Deletion I/D polymorphism of a 287 bp Alu repeat sequence in introns 16 of the ACE gene results in three genotypes I/D, D/D and I/I. The aims of this study were to evaluate ACE genotypes and allele frequency among HD patients and control subjects and to examine the association between ACE genotypes with HD risk. Methods: A retrospective casecontrol study included 186 subjects, 86 HD patients and 100 healthy individuals as a control. EDTA whole blood samples were collected from all participants for DNA extraction, and the ACE gene polymorphism was analyzed by using the Polymerase Chain Reaction (PCR) technique. Additionally, all individuals were requested to complete the questionnaire. Results: The initial results demonstrated that the D/D genotype was the most common genotype in all subjects and the association between ACE genotypes with HD occurrence was not statistically significant in the Gaza Strip-Palestine. Furthermore, no statistically significant association was detected between the polymorphism and the study groups (p-value = 0.511).

Objectives: To investigate the knowledge, awareness, and attitudes of school teachers towards breast cancer in Kaduna metropolis. Methods: A survey of school teachers aged 20 – 65 years was conducted in both public and private schools in Kaduna metropolis. A self-administered questionnaire was used to collect the data. Results: Out of the 997 participants, mean age 40.69 (SD = 12.09) years. Of all the participants, 259 (26.0%) were males, and 738 (74.0%) were females. The role of a teacher in disseminating information or knowledge cannot be overemphasized. Because of that crucial role they play thus makes it necessary that they have the right information so that they can transfer such to their students or wards. The children today represents the young generation that is growing. It will be good if they have the right knowledge about breast cancer concerning what breast cancer is, what causes it, knowledge of signs and symptoms, and what measures to take to prevent or treat it. Conclusion: This study shows that there is breast cancer awareness but there is low in-depth knowledge about the disease. There is low knowledge of risk factors, signs and symptoms, low response to breast self-examination (BSE), clinical breast examination (CBE) and mammography. Educational health programs can be organized to help create more awareness and knowledge about breast cancer which has the potential to help the public in making informed decisions thereby reducing the incidence of this disease.
