Each sample consists of a volume of 1 litre of water which had been obtained from multiple geographical locations. There were twelve water samples representing pure tap water sourced from various locations additionally, eight samples of mineral water were obtained from several marketplaces in Baghdad. A total of six radionuclides were detected in the water samples using the HPGe detector. These radionuclides were identified as Bi 214, Ra 226, TI 208, Bi 212, Pb 212, and K 40. Among these, Bi 214 and Ra 226 are part of the U-238 series, while TI 208, Bi 212, and Pb 212 belong to the Th 232 series. Additionally, K 40 is a naturally occurring radionuclide. The observed minimum value for the average specific activity of radionuclides in pure tap water samples was Al-Yarmouk Pure tap water. However, the sample Hay Al-qahira pure tap water exhibited the highest recorded specific activity values of radionuclides in pure tap water. The observed minimum value for the average specific activity of radionuclides in mineral water samples was Bardaa mineral water. However, the sample (W15) exhibited the highest recorded values for the specific activity of radionuclides in mineral water. The measured external dosage of natural radioactivity in water samples from Baghdad was found to be relatively low, at 0.366 mSv.y-1. This value falls below the recommended limit the United Nations Scientific Committee set on the Effects of Atomic Radiation (UNSCEAR), 1 mSv.y-1.","PeriodicalId":7494,"journal":{"name":"Al-Nahrain Journal of Science","volume":"43 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140267991","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 azo compounds have a variety of applications including dyes, pigments, and pharmaceuticals. The preparation and characterization of different azo compounds is an important area of research in organic synthesis. The azo compound synthesis typically involves the diazotization process for coupling between an aromatic amine and another aromatic compound containing an activating group such as -OH, -NH2, or -NR2. The reaction conditions must be carefully controlled to prevent side reactions, such as the formation of unwanted byproducts. Once synthesized, azo compounds can be characterized using a variety of techniques including UV-Vis spectroscopy, NMR spectroscopy, and mass spectrometry. UV-Vis spectroscopy is a commonly used technique for characterizing azo compounds. The absorption spectrum of an azo compound typically exhibits a strong absorption band in the visible region due to the delocalized π-electrons in the azo group. While in FTIR, the loss of the amine peak and showing a weak peak at about 1550 cm−1forthe (N=N) group, indicates the presence of Azo. The preparation and characterization of different azo compounds is a significant field of research in organic chemistry, which are applied as acid and base indicators, food coloring, optical switches, liquid crystal and in medicine.

Despite its ancestral use and wide applications in human health, scientific information on its oral safety remains scanty. In this study, the oral safety of 100 mg/kd/day, 200 mg/kg/day and 400 mg/kg/day of the aqueous fruit extract of Annona Muricata (AFAM) was evaluated in young adult, male and female white albino Wistar rats using standard acute and 42-days sub-chronic oral toxicity testing guidelines on anthropometric, biochemical, hematological and histo-pathological endpoints. In addition, preliminary qualitative and quantitative analyses of AFAM were undertaken using standard procedures. Results of the study showed that the estimated LD50 value for the acute oral toxicity study of AFAM calculated to be greater than 5 g/kg body weight/oral route although the testing was associated with transient but reversible behavioral toxicities. For its sub-chronic oral toxicity testing, AFAM treatment resulted in profound %weight gain, decreases in the serum triglycerides and very low density lipoprotein cholesterol and liver enzymes. Similarly, prolonged oral AFAM treatments caused significant decrease and increase in the differential neutrophils and platelet counts, respectively while the hist-opathological features of hepatic steatos is and renal tubule collapse in the AFAM-treated livers and kidneys, respectively suggested possible increased intrahepatic lipids biosynthesis and nephrotoxicity. The preliminary phytochemical analyses of AFAM showed the presence and relative amount of flavonoids, alkaloids, tannin, glycosides, saponin, and reducing sugars while the Gas Chromatography-Mass spectroscopy showed the relative abundance of thirteen compounds. Composite analyses conducted on the extract showed the presence of carbohydrate (64.65%), protein (2.14%), moisture content (8.07%), ash value (6.73%), lipid (14.22%) and fiber (4.19%). Overall, the study suggested that the prolonged AFAM oral treatments could predispose to the development of fatty liver disease from de novo intrahepatic biosynthesis of triglycerides, nephrotoxicity and hematotoxicity. In conclusion, the results of this study showed that prolonged consumption of AFAM should be with a great caution as it could pose serious health concerns.","PeriodicalId":7494,"journal":{"name":"Al-Nahrain Journal of Science","volume":"588 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140281150","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}

It plays a crucial role in determining an individual's sex and contains genetic information that can be useful in forensic and human identity testing. Unlike autosomal DNA, which is inherited from both parents, the X chromosome is inherited differently in males and females, making it useful in certain types of analyses. In forensic investigations, the X chromosome can be used to determine the sex of an individual, which can be useful in identifying potential suspects or victims. Additionally, X chromosome analysis can be used to link evidence samples to a particular individual or to exclude individuals as potential contributors of the evidence. This can be particularly useful in cases where the evidence sample is a mixture of DNA from multiple individuals. In human identity testing, the X chromosome can be used in situations where other types of DNA analysis are not possible or inconclusive. For example, in cases where a potential parent is unavailable for testing, analysis of the X chromosome can be used to determine if a child is likely to be their biological offspring. Similarly, in cases where traditional autosomal DNA analysis is inconclusive, X chromosome analysis can be used to provide additional information about the biological relationship between individuals. However, there are some limitations to the use of X chromosome analysis in forensic and human identity testing. One limitation is that it is not as informative as autosomal DNA analysis, as it contains less genetic information. Additionally, the inheritance patterns of the X chromosome can be complex, particularly in cases where there are multiple generations involved. Therefore, X chromosome analysis should be interpreted in conjunction with other types of DNA analysis and other forms of evidence to ensure accurate and reliable results. Overall, the use of X chromosome analysis in forensic and human identity testing can provide important information in certain situations, particularly where traditional DNA analysis is not possible or inconclusive. As such, it is an important tool in the fields of forensic science and human identification.","PeriodicalId":7494,"journal":{"name":"Al-Nahrain Journal of Science","volume":"14 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140268583","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}
