Information comes in many forms, and its conveyance necessitates a wide variety of methods of communication. We must communicate these types of data over a secure communication channel on the internet because they include confidential and sensitive information. One of the most challenging issues was figuring out how to send sensitive information without raising suspicion. Cryptography and steganography are just two examples of many methods used to conceal information from prying eyes, all to protect sensitive data from being misused or altered by unauthorized parties. Using an encryption method, cryptography transforms information from its original, easily decipherable form (plain text) into a completely meaningless one (cipher text). We can also use a decryption technique to change the encrypted text back into plain text. Steganography is a technique used to transmit information through other forms of digital media secretly. Due to the difficulty in visually detecting hidden data, the image will serve as the cover media for this thesis. The well-known method used to conceal confidential information is LSB (Least Significant Bit). The LSB method is based on exchanging bits of the cover medium for bits of private data.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126708511","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 study aimed to investigate the A. muricata leaves extract and its active fraction in inhibiting cell proliferation in the human MDA-MB-231 cell line as a model of Triple Negative Breast Cancer. MDA-MB-231 cell lines were seeded and maintained in RPMI 1640 culture medium. RNAs were isolated from non-treated MDA-MB-231 and treated cell lines with A. muricata DMSO extract after 72 hrs incubation using TriPure isolation reagent. qRT-PCR was applied to measure the gene expression of P 53 , and Bcl 2 against the β-actin gene as an internal control. Protein analysis of BRCA 1 , BRCA 2 , EGFR , p53, Bcl2, Cytochrome C , and Caspase3 gene expression was carried out by ELIZA immunoassay. The level of expression of the pro-apoptotic P 53 gene in the treated cell line with A. muricata DMSO extract was overexpressed, indicating its potential efficacy in directing cancer cells toward programmed death. On the other hand, the treated cell line significantly ( P = 0.05) showed low expression of BRCA 1 , BRCA 2 , and EGFR when compared to the negative control. The present study revealed that A. muricata leaves extract is a promising inhibitor of cell proliferation in the MDA-MB-231 cell line (TNBC), and has efficacy against BRCA 1 , BRCA 2 , and EGFR gene expression. Since this plant is widely consumed by humans and is non-toxic, it could be developed quickly for chemoprevention and intervention in breast cancer patients.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115585505","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 space-time is modeled by Bianchi type 𝑉𝐼 0 cosmological model. The field equations' solution is obtained considering that the scalar expansion θ of the cosmological model is proportional to the eigenvalue 𝜎 11 of the shear tensor 𝜎 𝑖𝑗 . The thermodynamic functions are studied for the universe and their values are compared in general relativity and Lyra geometry. For all obtained models, the entropy is consistent with the second law of thermodynamics. The physical and geometrical properties of the obtained models are discussed. Also, we show that the Lyra term 𝛽 plays the role of the variable cosmological term in the relativity theory and can not be identified as a viscosity term. Without the viscosity term, we obtain the entropy as a constant 𝑺 = constant. That is the universe is in an adiabatic state. The Bianchi type 𝑉𝐼 0 cosmological model presented in this paper explains a stage of evolution with the positive deceleration parameter.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122780385","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 amplification and fundamental resonance frequency and of ground motion at different frequencies were estimated using the microtremor data measured at ten sites in the new industrial zone around the urban areas in Sohag Governorate, Egypt. Also, site effects were calculated applying a numerical technique using shear wave velocities observed from measured profiles at the study area utilizing 24-channel shallow seismic refraction seismograph. The results show variations in the fundamental resonance frequency values from one site to another depending on its distance from the Eocene plateau scarp that located at the southern and southwestern sides of the study area, where it becomes higher close to the plateau foot. In case of the low frequency, the amplification of the ground motion shows variation from site to the other site depending on its vicinity to the plateau, while in case of high frequency the variation depends on the thickness of the sediment layers. The results using the microtremor technique emphasize that given by the shallow seismic refraction method.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114662896","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}

Fifth group was given DPP 12 hrs before administration of DPP, while the sixth group was given BPA 12 hrs before administration of BPA. The seventh group was given Vit. C 12 hrs before administration of BPA, whereas the eighth group was given BPA 12 hrs before administration of vit. C. The ninth group was given DPP combined with Vit. C 12 hrs before administration of BPA.BPA induced histopathological changes in the stomach indicated by congestion at the vasculatureand edema of the submucosal layer of the non-glandular part, and congestion of the blood vessels at the muscular layer of the glandular part. However, administration of each DPP and vitamin C before and after BPA, or combined with each other before BPA, restored the normal histological structure of the stomach. So, this study revealed that DPP and Vit. C protected and ameliorated gastric structure against BPA toxicity via their antioxidant activities.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"284 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116572190","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}

At the same theoretical level, the vibrational frequencies (FT-IR) of the titled compound were determined and scaled down using a factor of 0.961. Also, at the same level of theory, the electronic spectrum of the mentioned molecule was theoretically estimated using Time-Dependent Density Functional Theory (TD-DFT) in gas phase. The mentioned molecule was subjected to molecular docking investigations to determine its inhibitory activity against the breast cancer receptor (PDB ID: 3I89), the HCV receptor (PDB ID: 5TRH), the HBV receptor (PDB ID: 5T2P), and the HAV receptor (PDB ID: 5WTG). According to the findings, the aforementioned compound has a higher maximum binding affinity for HBV than the others do. Consequently, it might be a good candidate for an antiviral therapy.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130263269","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}
