This research intends to analyze the high-quality plan using accomplishment, conformance, and homogeneity criteria.\u0000The study involved 40 patients with a postnasal cancerous tumor. The patients underwent computed tomography (CT) simulation to scan the anatomical details of the patients' heads. Then, their data was forwarded to the treatment planning system (TPS) workstation for IMRT and VMAT planning. The plans were evaluated using the IOA, HI, and CI indices.\u0000The nasopharynx coverage results consist of the GTV and PTV at 95%. The statistical study reveals that VMAT provides much more coverage than IMRT for 95% GTV and 95% PTV. The results reveal that VMAT has a substantially better-quality plan (IOA) than IMRT. IMRT provides a superior CI, but VMAT protects the cochlea and optic nerves more effectively. In addition, the IMRT is advantageous for the preservation of additional OARs. There is no statistical difference in protection for the mandible and parotid glands between the two procedures. The VMAT has superior coverage for the gross and planned target volumes and achievement indices. The conformity of IMRT in the tumor target area is better, while VMAT can better protect the cochlea and optic nerves.","PeriodicalId":511333,"journal":{"name":"Ibn AL-Haitham Journal For Pure and Applied Sciences","volume":"94 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140501680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MONCs with various morphologies have been created by physical, chemical, and biological processes, such as sol-gel, hydrothermal, co-precipitation, solvothermal, and microwave irradiation. Eugenol (4-allyl-2-methoxyphenol) is a major component of clove essential oil and it was found in various plant groups, has been widely utilized, and famously stated to have a variety of important biological activities. It is a good starting material for the synthesis of a wide variety of derivatives with different activity.

Obesity is a shortcut to many diseases, such as hypertension, diabetes, atherosclerosis, and other chronic diseases. Oxidative stress increases obesity through free radicals. Glutathione S-transferase (GST) is a metabolic enzyme used to remove toxins. This study aimed to determine GST activity in obese patients as a predictor of oxidative stress and the effectiveness of lipid profiling in obese patients. The study included 139 samples of obese and healthy people (obese group 84 and healthy group 55). Both groups (obese and healthy groups) were divided into four groups based on body mass index. Blood samples were collected from obese males and females in Al-Yarmouk Hospital. Some biochemical parameters were measured for all study groups, including estimation of lipid profile, FSG, and GST activity. Results have shown a significant increase in low-density lipoprotein cholesterol (LDL-C) in obese groups and showed a rise in GST levels in healthy groups compared with obese groups (p < 0.05). These studies show that being overweight or obese makes you more likely to get heart disease and other illnesses. It has been demonstrated that the slightly lower levels of GST in the overweight and obese groups compared to other groups demonstrate the precise role of GST in its decrease with weight gain, along with an increase in LDL-C level.","PeriodicalId":511333,"journal":{"name":"Ibn AL-Haitham Journal For Pure and Applied Sciences","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140501967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the actual cause is unknown, PCOS is regarded as a complicated genetic characteristic with a great degree of variability. Moreover, hormones and immune cells, including both innate and acquired immune cells, are thought to interact in PCOS. Chronic low-grade inflammation raises the risk of autoimmune disease. The study's purpose is to investigate the chemokine monocyte chemoattractant protein-1 (MCP-1) and fertility hormones in samples of women patients with polycystic ovary syndrome (PCOS) in the City of Medicine. Sixty PCOS women comprise 30 healthy control women; their average age was 20–40 years, and their weight ranged from 60 to 100 kg. The results showed an increase in the level of MCP1 in PCOS patients, but this increase was not significant (P<0.05), which was not influenced by BMI or fertility hormones. As well as elevated fertility hormones, this study, when compared to controls as well as patients with PCOS, showed a significant increase in the level of testosterone (14.63 ±2.30 nmol/L) while in control women (0.627 ±0.04), LH hormone in patients and control group (6.54 ±0.51 mIU/mL), and 2.93 ±0.18, respectively. Prolactin hormone was increased in PCOS patients (16.27 ±1.25 ng/mL) when compared to the control group (12.85 ±0.62). There was no significant difference in FSH hormone in women with PCOS (5.27 ±0.28 mIU/mL) compared with the control group (5.59 ±0.18).","PeriodicalId":511333,"journal":{"name":"Ibn AL-Haitham Journal For Pure and Applied Sciences","volume":"104 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140501860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method depends on changing the physical and chemical properties of a part of the specimen spread out from the specimen injected into the carrier stream. The CFIA technique uses automatic analysis of samples with high efficiency. The CFIA PC compatibility also allows specimens to be treated automatically, reagents to be added, and reaction conditions to be closely monitored. The CFIA is one of the automated chemical analysis methods in which a successive specimen sample is to be estimated and injected into a vector stream from a flowing solution that meets the reagent and mixes at a specific point, the y-junction, before reaching the detector. However, CFIA does not have a separation method because the sample, carrier stream, and reagent all enter the system simultaneously and move together at a specific flow rate to the end of the system. It is also possible to inject a second specimen sample to be estimated before the first sample reaches the detector. For all the reasons mentioned, the CFIA technique analysis is appropriate, fast, and ideal for analyzing different samples. This general technique deals with solutions and is used for various tasks, including pH measurement, conductivity, colorimetry, titration, and enzyme assays. So, it was used in analytical chemistry to estimate many samples, including medicines, because they are essential substances for human life, and everyone widely uses them.","PeriodicalId":511333,"journal":{"name":"Ibn AL-Haitham Journal For Pure and Applied Sciences","volume":"34 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140502223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
