(Onion). Onion is cultivated all over the world.  Onion bulbs are composed of polysaccharides such as peptides, fructans, flavonoids (mostly quercetin), saccharose and organosulfur compounds having salutary effects on human health. Onion is beneficial for human health since it has a high nutritional value. The nutritional constituents of an onion bulb are crude oil, vitamin E, sodium, potassium, and zinc. The onion bulb has the potential to reduce diseases such as stomach cancer, osteoporosis, and brain cancer in human beings. Additionally, onion is antidiabetic, anti-inflammatory, anti-scar, antispasmodic, antiseptic, anti-genotoxic, anti-mutagenic, diuretic, anti-parasitic, antimicrobial, antipyretic, and analgesic. \u0000Copyright(c) The Authors","PeriodicalId":137307,"journal":{"name":"Scientific Inquiry and Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131813735","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 quality parameters examined in the water samples were pH (acidity), total dissolved solids (TDS), and electrical conductivity (EC). A total of 20 samples were randomly collected from different sources of drinking water, namely dug well and hand pump, from the study area. The results showed that the quality parameters of water samples taken from the hand pump were not within the appropriate range (pH range was 5.7-6.0 and TDS range was 1579-2120 mg/L), while those of well water samples were within range (pH range was 5.09-6.60 and TDS range was 497-1182 mg/L). Therefore, it was concluded that water from the well sources was safe for consumption as per the guidelines set by WHO and EPA and could be used for drinking purposes. The findings revealed that water from the hand pump sources had high TDS and EC (greater than WHO limit), which pose several health risks. It was noted that TDS is directly proportional to electrical conductivity and inversely proportional to the pH level of water. Further, it was recommended that future studies need to be conducted at regular intervals to evaluate the quality of drinking water in rural areas of Sindh province, so that authorities can promptly provide solutions to such issues. \u0000Copyright (c) The Authors","PeriodicalId":137307,"journal":{"name":"Scientific Inquiry and Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126702060","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 electron and photon beam characteristic are essential to study before calibration of machine. This study focused on the dosimetric characteristics of different energies of electron beams for different field size. The basic objective of this work is, to calculate dosimetric parameters and characteristics of electron beam, specially depth dose characteristics along central axis. In this work, 6 MeV, 9 MeV, 12 MeV, 15 MeV and 18 MeV of electron beam and 6 MV and 15 MV of photon beam with different field size is used. Characteristics of depth dose of electron and photon beam in water have analyzed to provide better quality of radiation therapy treatment planning. The different beam characteristics are due to different interactions that occurs between electron beams giving them a definite range whereas photon beams are attenuated leading to dose deposition and much larger range with no definite end. Depth dose characteristics of electron and photon beams do not show same characteristics as interaction of beam with matter depends on the quality of beam. Attenuation and penetration factors change with changing dosimetric parameters. Complete analysis of dosimetric characteristics of electron and photon beam help to choose more accurate beam for the treatment of cancer. This work will help to increase accuracy in treatment of cancer with radiotherapy.","PeriodicalId":137307,"journal":{"name":"Scientific Inquiry and Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125375832","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}

Excessive glucose levels and failure of one’s body to produce or manage glucose, trigger diabetes. Glucose is known to be responsive to NIH3T3 cells as it alters the expression of a range of genes associated with inflammation and apoptosis. In this study, the toxic effect of glucose was evaluated on NIH3T3 fibroblasts. Cells (NIH3T3) were cultured in media (DMEM), supplemented with 10% FBS and 1% Penicillin-Streptomycin. MTT assay was performed to check the toxic effect of glucose. NIH3T3 cells were treated with high glucose (30mM) for 24 hours. Trizol was used to extract the RNA followed by PCR reactions for gene expression analysis. Glucose treatment for 24 hours, modulated the expression of BCL-2 and BAX genes. The expression of BCL-2 was reduced while a significant increase was noticed in the expression BAX gene. Our results illustrated that glucose has some toxic effects on NIH3T3 cells. Glucose induces apoptosis by upregulating BAX and down-regulating BCL-2 expressions.","PeriodicalId":137307,"journal":{"name":"Scientific Inquiry and Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126561010","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}
