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 (VMAT) in the Monaco 5.1 version, and then those plans will be forwarded to the Infinity Linear Accelerator (LINAC). For the purposes of evaluation, the dose volume histogram is utilized to perform the calculation necessary to determine the dose for tumors and Organs at Risk (OAR). After that, the modulation complexity score, also known as the MCS, was determined using the multiyear collimators of the plans. Results: Showed that the mean age of males was (82.6 ± 4.93) years, while the mean age of females was (72.12 ± 3.13) years. The proportion of males was significantly higher than that of females. The female patient had a higher body mass index than the male patient. The mean height of men in this study was (172.85 ± 2.02) cm, while the mean height of women was (156.32± 1.21) cm. The coverage planning target volume (PTV) for the left lung tumor shows that the VMAT was significantly higher than the IMRT at 95%, 98%, 5%, and 2%. When comparing IMRT and VMAT for the PTV 105%, there was no discernible difference between the two. According to the statistics, the conformity and homogeneity of the dose delivered by the VMAT was noticeably higher than those delivered by the IMRT. According to the findings of the study, the MCS score for the VMAT is noticeably higher than that of the IMRT. In the case of the IMRT technique, the relationship between the MCS and the total number of monitor units was found to be positive and direct, whereas in the case of the VMAT technique, the relationship was found to be negative and inverse. Conclusions: The volumetric modulated arc therapy (VMAT) shows a better coverage and less complexity technique and could protect the heart, spinal cord, and right lung than the IMRT.

Ocular Drug Delivery Barriers—Role of Nanocarriers in the Treatment of Anterior Segment Ocular Diseases
...Show More Authors

Ocular drug delivery is challenging due to the presence of anatomical and physiological barriers. These barriers can affect drug entry into the eye following multiple routes of administration (e.g., topical, systemic, and injectable). Topical administration in the form of eye drops is preferred for treating anterior segment diseases, as it is convenient and provides local delivery of drugs. Major concerns with topical delivery include poor drug absorption and low bioavailability. To improve the bioavailability of topically administered drugs, novel drug delivery systems are being investigated. Nanocarrier delivery systems demonstrate enhanced drug permeation and prolonged drug release. This review provides an overview of ocular barr

The Role of Monoamine Oxidase and Atherogenic Index in Newly Diagnosed and Tamoxifen Treated Women with Breast Cancer Disease
...Show More Authors

Breast cancer (BC) is one of the most frequently observed malignancy in females worldwide. Today, tamoxifen (TAM) is considered as the highly effective therapy for treatment of breast tumors. Oxidative stress has implicated strongly in the pathophysiology of malignancies. This study aimed to investigate the changes in the levels of oxidants and antioxidants in patients with newly diagnosed and TAM-treated BC. Sixty newly diagnosed and 60 TAM-treated women with BC and 50 healthy volunteers were included in this study. Parameters including total oxidant capacity (TOC), total antioxidant capacity (TAC), and catalase (CAT) activity were determined before and after treatment with TAM. The serum levels of TOC and oxidative stress index (OSI) were

Detection of EGFR Mutations in Bronchial Wash from Iraqi patients with nonsmall Cell Lung Cancer (NSCLC)
...Show More Authors

Background: Non-small cell lung cancer (NSCLC) is caused of 85% of all lung cancers. Among the most important factors for lung tumor growth and proliferation are the tyrosine kinase receptors that coded by the epidermal growth factor recep-tor (EGFR) gene. Activation of EGFR ultimately leads to developing of lung cancer. The present study was undertaken with an objective to detect EGFR mutations in bronchial wash from Iraqi patients with NSCLC before treatment. Methods: DNA was extracted from bronchial wash samples collected from 50 patients with NSCLC by using a Qiamp DNA Mini Kit (Qiagen, Hilden, Germany). Then, EGFR mutations were determined by using real-time RCR combined with two technologies, Amplification Refractory Mutation System (
