This research introduce a study with application on Principal Component Regression obtained from some of the explainatory variables to limitate Multicollinearity problem among these variables and gain staibilty in their estimations more than those which yield from Ordinary Least Squares. But the cost that we pay in the other hand losing a little power of the estimation of the predictive regression function in explaining the essential variations. A suggested numerical formula has been proposed and applied by the researchers as optimal solution, and vererifing the its efficiency by a program written by the researchers themselves for this porpuse through some creterions: Cumulative Percentage Variance, Coefficient of Determination, Variance

Background:sThe aims of this study were to evaluate and compare the ability of three different techniques to obdurate simulated lateral canals, evaluate the effect of the main canal curvature on obturation of lateral canals and compare the gutta-percha penetration between coronal and apical lateral canals. Materials and methods: Resin blocks with 30 straight and 30 curved were used in this study. Each canal has two parallel lateral canals. The main canal has 0.3 mm apical diameter and 0.04 taper. The canals were divided into six groups according to canal curvature and obturation techniques used (n=10): Groups C1 and C2: straight and curved canals obturated with continuous wave technique using E&Q masterTM system. Groups O1 and O2: straight

Background: Adults with Acute Myelogenous Leukemia (AML) have the lowest survival rate of all leukemias. Complete remission (CR) rate after induction therapy is about 55-85%, however 30% of patients fail to achieve remission and they remain alive only for about a year. Consolidation chemotherapy results in 5-year overall survival (OS) of about 30%.

Objectives: To study characteristics of adult patients with AML who attended Baghdad Teaching Hospital, their response to induction therapy and then to consolidation therapy, and their 5-year (OS) and disease free survival (DFS).

Results: Eleven patients who received attenuated induction therapy had a median survival of 6-8 mon

Background: Chronic myeloid leukemia (CML) is a clonal stem disease with distinctive clinical course which is ultimately fatal. It is characterized by the presence of Philadelphia
chromosome (t 9:22).Tyrosine kinase inhibitors like imatinib mesylate as targeted therapy had revolutionized the management of CML with significant prolongation of overall survival and
decreased rate of blastic transformation.
Objective:This study will describe the experience of treating 44 Iraqi patients with chronic myeloid leukemia by imatinib at the National Hematology Centre in Baghdad.
Patients and Methods:This study included 44 Iraqi patients diagnosed in Chronic phase CML at the National Centre of Hematology in Baghdad fr

Diabetic nephropathy (DN) is a principle cause of microangiopathy and the main reason for kidney disease at the end stage in patients with type 2 diabetes mellitus (T2DM). This work aimed to study the relation of pentosidine with kidney injury in the case of diabetic nephropathy. This study included 75 patients suffering from T2DM and 75 apparently healthy subjects. The patients group was divided into three groups ((normoalbumin, microalbuminuria, and macroalbuminuria; 25 patients for each) on the basis of albumin-creatinine ratio (ACR) . The level of serum pentosidine was determined using an ELISA kit. The level of pentosidine was found to be significantly higher in DN patients than in the healthy group. Also, the results revealed a str

Objective(s): to assess the factors which are associated with the prolonged prehospital delay of patients with
acute myocardial infarction.
Methodology: A descriptive study was conducted at the Coronary Care unit (CCU) in Al-Yarmok Teaching
Hospital, Ibn AL-Nafis Hospital for Cardiovascular Diseases, AL-Kadumia Teaching Hospital, Baghdad Teaching
Hospital, and AL-Kindy Teaching Hospital during the period of the study from February 2

With the vast usage of network services, Security became an important issue for all network types. Various techniques emerged to grant network security; among them is Network Intrusion Detection System (NIDS). Many extant NIDSs actively work against various intrusions, but there are still a number of performance issues including high false alarm rates, and numerous undetected attacks. To keep up with these attacks, some of the academic researchers turned towards machine learning (ML) techniques to create software that automatically predict intrusive and abnormal traffic, another approach is to utilize ML algorithms in enhancing Traditional NIDSs which is a more feasible solution since they are widely spread. To upgrade t
