Estimation of tumor and local tissue dose in gold nanoparticles radiotherapy for prostate cancer
...Show More Authors

The objective of this research was to estimate the dose distribution delivered by radioactive gold nanoparticles (198 AuNPs or 199 AuNPs) to the tumor inside the human prostate as well as to normal tissues surrounding the tumor using the Monte-Carlo N-Particle code (MCNP-6.1. 1 code). Background Radioactive gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated to treat prostate cancer in animals. In order to use them as a new therapeutic modality to treat human prostate cancer, accurate radiation dosimetry simulations are required to estimate the energy deposition in the tumor and surrounding tissue and to establish the course of therapy for the patient. Materials and methods A simple geometrical model of a human prostate was used, and the dose deposited by 198 AuNPs or 199 AuNPs to the tumor within the prostate as well as to the healthy tissue surrounding the prostate was calculated using the MCNP code. Water and A-150 TEP phantoms were used to simulate the soft and tumor tissues. Results The results showed that the dose due to 198 AuNPs or 199 AuNPs, which are distributed homogenously in the tumor, had a maximal value in the tumor region and then rapidly decreased toward the prostate–tumor interface and surrounding organs. However, the dose deposited by 198 Au is significantly higher than the dose deposited by 199 Au in the tumor region as well as normal tissues. Conclusions According to the MCNP results, 198 AuNPs are a promising modality to treat prostate cancer and other cancers and 199 AuNPs could be used for imaging purposes. Abstract

Fingerprints Recognition Using the Local Energy Distribution over Haar Wavelet Subbands
...Show More Authors

Fingerprints are commonly utilized as a key technique and for personal recognition and in identification systems for personal security affairs. The most widely used fingerprint systems utilizing the distribution of minutiae points for fingerprint matching and representation. These techniques become unsuccessful when partial fingerprint images are capture, or the finger ridges suffer from lot of cuts or injuries or skin sickness. This paper suggests a fingerprint recognition technique which utilizes the local features for fingerprint representation and matching. The adopted local features have determined using Haar wavelet subbands. The system was tested experimentally using FVC2004 databases, which consists of four datasets, each set holds

...Show More Authors
Abstract<p>The synthesis oxadiazole derivative 2,5-disubstituted-1,3,4oxadiazole (3a,3b,3c) was prepared from reaction of N-(4-amino benzene sulphonyl)Morpholipebut-2-enehydrazide with (4-hydroxybenzaldehyde,4-methoxy benzaldehyde,4-ethoxybenzaldehyde) in the presence of lone as catalyst. The structure of (3a,3b,3c) was characterized by using FT-IR, H-NMR and spectroscopy. Nanoparticles of the prepared compounds have been fabricated in aqueous media using re-precipitation method.Characterization of the nano particles (ONPs) have been performed by using UV-VIS spectrophotometer and scanning electron micro scope ( SEM). The size of the nanoparticales were around 150-200 nm as indicated by (SEM). T</p> ... Show More

The role of Modulation Complexity Score (MCS) of the VMAT and IMRT techniques in the treatment planning of left non-small lung cancer
...Show More Authors

Background: Lung cancer is a common disease for patients over the age of 50 years, especially males due to smoking habits. This study aimed to compare the modulation complexity score (MCS) for the advanced treatment planning techniques which the intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT). Materials and Methods: Thirty patients who had non-small lung cancerous tumors on their left side participated in this study. The range ages were 68 to 98 years, the heights were between 151 and 182cm and they having weights from 46 to 79 kg. For Each patient will create two plans dial using two different techniques, which will be Intensity Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy

Waterpipe tobacco smoking and gene variants of CYP1A1-Ile462Val and -MspI polymorphisms are possibly associated with the risk of lung cancer in the Iraqi population
...Show More Authors

Background: Previous studies about the correlation of genetic polymorphisms in the multigene family of cyto- chrome P450 (CYPs), the effect of tobacco smoking, and the risk of developing cancer have been well in- vestigated in different populations, but not in Iraq. Furthermore, the studies of malignance occurrence re- lationship with cigarette tobacco smoking revealed the presence of strong association, however, little is known about the risk of Waterpipe (WP) tobacco smoking. Thus, determination two important genetic polymorphisms in CYP1A1, a main member of CYPs, among Iraqi men was our first aim. This is the first study that highlights the correlation of CYP1A1 polymorphisms with the risk of lung cancer in Iraq. The second aim was to ev

Comparative of Green-Synthesis of Bimetallic Nanoparticles Iron/Nickel (Fe/Ni) and Supported on Zeolite 5A: Heterogeneous Fenton-like For Dye Removal From Aqueous Solutions
...Show More Authors

Green synthesis of bimetallic nanoparticles of Fe/Ni (G-Fe/Ni-NPs) and zeolite-5A supported (G-Z-Fe/Ni-NPs) as heterogeneous Fenton-like oxidation for the decolourisation of reactive red 120-dye (RR120) from the aqueous medium using green tea extract as a reducing agent. Zeolite-5A from local kaolin is prepared and characterised using the hydrothermal method and is used as a supporting material for Fe/Ni-NPs. (SEM), (EDX), (AFM), (XRD), (FT-IR), (BET). Its zeta potential were used to characterise G-Fe/Ni-NPs and G-Z-Fe/Ni-NPs. The decolourisation efficiency (Ed) of the RR120-dye using a heterogeneous Fenton-like for G-Fe/Ni-NPs and G-Z-Fe/Ni-NPs is 99.8% and 99.9%, respectively, under the optimum conditions: [H2O2] = 20 and 1 mmol/L

Nadaraya-Watson Estimation of a Circular Regression Model on Peak Systolic Blood Pressure Data
...Show More Authors

Purpose: The research aims to estimate models representing phenomena that follow the logic of circular (angular) data, accounting for the 24-hour periodicity in measurement. Theoretical framework: The regression model is developed to account for the periodic nature of the circular scale, considering the periodicity in the dependent variable y, the explanatory variables x, or both. Design/methodology/approach: Two estimation methods were applied: a parametric model, represented by the Simple Circular Regression (SCR) model, and a nonparametric model, represented by the Nadaraya-Watson Circular Regression (NW) model. The analysis used real data from 50 patients at Al-Kindi Teaching Hospital in Baghdad. Findings: The Mean Circular Erro
