A Blended Learning Program Based on the Next Generation Standards (NYS) to Develop the Teaching Performance of Middle School Mathematics Teachers and Some Students’ Future Thinking Skills
...Show More Authors

Abstract

The aim of the current research is to prepare an integrated learning program based on mathematics standards for the next generation of the NYS and to investigate its impact on the development of the teaching performance of middle school mathematics teachers and the future thinking skills of their students. To achieve the objectives of the research, the researcher prepared a list of mathematics standards for the next generation, which were derived from a list of standards. He also prepared a list of the teaching competencies required for middle school mathematics teachers in light of the list of standards, as well as clarified the foundations of the training program and its objectives and the mathematical practices that include. Additionally, he prepared an electronic skill test for mathematics teachers and a test for future thinking skills for pupils on the stage. The research sample consisted of a group of mathematics teachers at the intermediate stage, numbering (40) teachers who were divided into two experimental and control groups, and a group of intermediate school students; whose number reached (60) students, were divided into two experimental and control groups as well. The results revealed that there are differences between the experimental and control groups of teachers in the post-measurement of the skill-test of the teaching performance in favor of the experimental group and in the pre-post-test measurements of the experimental group in favor of the post-measurement, The results showed also that there are differences between the experimental and control groups of students in the post-measurement to test future thinking skills in favor of the experimental group and differences in the pre-post measurements to test the future thinking skills of the experimental group of students in the intermediate stage in favor of the post-measurement. In light of these results, the researcher presented a set of recommendations for training and preparing mathematics teachers and also made some suggestions for future research similar to the current research.

Hong-Ou-Mandel Dip Measurements of Two Independent Weak Coherent Pulses for Free Space Quantum Key Distribution Systems
...Show More Authors

Preparation of identical independent photons is the core of many quantum applications such as entanglement swapping and entangling process. In this work, Hong-Ou-Mandel experiment was performed to evaluate the degree of indistinguishability between independent photons generated from two independent weak coherent sources working at 640 nm. The visibility was 46%, close to the theoretical limit of 50%. The implemented setup can be adopted in quantum key distribution experiments carried out with free space as the channel link, as all the devices and components used are operative in the visible range of the electromagnetic spectrum.

Molecular diagnosis of bcr-abl fusion gene in CML patients using Monoplex-Two Steps- Reveres Transcriptase–Polymerase Chain
...Show More Authors

Background: Chronic myeloid leukemia (CML) is a stem cell disorder associated with an acquired chromosomal abnormality, Philadelphia chromosome (Ph), which arises from the reciprocal translocation of part of long arm of chromosome 9, in which proto-oncogene ablson gene (abl) is located, to long arm of chromosome 22, in which break point cluster region gene (bcr) is located. The bcr-abl fusion gene can be detected using several molecular methods. For its simplicity, rapidity, and sensitivity, Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) is one of the most common techniques used for analyzing whether a target gene is being expressed or not.
Patients and methods: Venous blood (VB) sample from hem

Protection Effects of Vernonia Amygdalina Methanolic Extracts Against Hepatocellular Damage Induced by Petroleum Contaminated Diets in Male Rats
...Show More Authors

Recently, bitter leaf (Vernonia amygdalina) was found to prevent petroleum – induced toxicities on the kidney whereas it potentiates the toxic effect of petroleum adulterated diet on the testes of animal model. This differential action has elicited further inquest into the role of bitter leaf extract in other organs in the midst of petroleum affronts. The hepatoprotective ability of Vernonia amygdalina methanol extract (VAME) is the objective of this investigation.  Administration of VAME significantly (P <0.05) reduced serum liver function indices relative to the control. In addition, the activities of liver oxidative enzymes, energy metabolizing enzymes and oxidative stress indices altered by crude oil

Humoral immune factor changes in group of patients with Non-muscle invasive bladder cancer treated with intravesical therapy.
...Show More Authors

Background: Bladder cancer (BC) one of the most common urologic cancer characterized by the highest recurrence rate, many types belong to BC, but most common of them worldwide are transitional cell carcinoma(TCC) which constitute about 90-95% cases, squamous cell carcinoma (SCC) and adenocarcinomas
Objective: This study was designed to evaluate parameters of humoral immunity in Non-muscle invasive (superficial or early) bladder cancer patients in Iraq that may provide a new insight into the future of immunotherapies development and BC management.
Materials and methods: Fifty-nine volunteer's patients ranged from 24 to 83years old, and 30 control individuals ranged from 51-80 years old, who attended and admitted to Hospital of Gazi

High Serum High Mobility Group A1 (HMGA1) Levels are associated with presence of Metabolic Syndrome: Case-control study
...Show More Authors

Background: Metabolic syndrome is a complex series of metabolic defects, characterized by high levels of serum glucose, hypertension, abdominal obesity, and dyslipidemia. The high mobility group AT-hook1, an architectural transcript factor, affects the homeostasis of glucose. No previous studies have been performed to examine whether HMGA1 can be secreted into the extracellular milieu.

Objectives: this case-control study aimed to examine whether HMGA1 secretes into the extracellular milieu and compares its serum level in two groups of metabolic syndrome (with and without diabetes) and a control group composed of apparently healthy individuals of Iraqi population with different nationalities.

...Show More Authors

Background: Tooth wear is one of the most common problems in the older dentate population which results from the interaction of three processes (attrition, abrasion and erosion) and it affects all societies, different age groups, and all cultures. This study was achieved to evaluate the prevalence and distribution of tooth wear among institutionalized residents in Baghdad city\ Iraq.

...Show More Authors

Heart failure (HF) is characterized by family history and clinical examination combined with diagnostic tools such as electrocardiogram, chest x-ray and an assessment of left ventricular function by echocardiography. An early diagnosis of heart failure is still based on symptoms of dyspnea, fatigue and signs of fluid overload. Serum N-terminal pro-B-type natriuretic peptide (NT-pro BNP) is cardiac biomarker has emerged as potential predictor of heart failure. It is used as a sensitive biomarker in diagnosis and assessment severity of heart failure. This study assed the diagnostic value of (NT-pro BNP), in Iraqi children patients with heart failure and its correlation with LVEF% especially in emergency rooms of hospitals.Ninety (90) consecut
