Among the various types of dermatological malignancy, melanomas are particularly malignant and responsible for a significant number of cancer-related deaths. Early skin cancer detection plays a crucial role in reducing mortality rates and saving lives. So, Computer-Aided Diagnosis (CAD) systems that are driven by machine learning algorithms can help to detect melanoma early. In this article, we propose an innovative approach to melanoma recognition through the development of a fully automatic CAD system. To elevate the overall quality of input dermatoscopic images, we apply a series of preprocessing techniques such as median filtering and bottom-hat filtering. Besides that, an adaptive segmentation method based on the well-known Otsu thresholding technique is conducted to accurately extract suspected skin lesion regions from the improved input image. Then, we use the Local Binary Pattern (LBP) feature extraction method to characterize segmented skin lesions. This technique enables us to capture relevant information from the lesions effectively. Ultimately, the extracted features are inserted into a Decision Tree (DT) classifier to categorize each melanocytic cutaneous lesion in a given dermatoscopic image as either benign or melanoma. The proposed method is effectively tested and verified using a 10-fold cross-validation approach, achieving 90.35%, 88.47%, and 86.28% for average diagnostic accuracy, sensitivity, and specificity, respectively. The experimentation is conducted on the ISIC database, which contains suspect melanoma skin cancer cases, utilizing the MATLAB environment.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"102 3-4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140517155","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 cultivation of edible oyster mushroom Pleurotus floridanus (EMPF) was carried out utilizing a hanging technique based on different substrate cultures including rice straw, wheat straw, a mixture of rice and wheat straw, a mixture of agricultural lime and wheat straw, a mixture of agricultural lime and rice straw, a mixture of quicklime and rice straw. After that, this research work analyzed the carbohydrate and protein contents in addition to investigating the antioxidant performance of EMPF as a species of oyster mushroom to improve awareness of the beneficial impact of EMPF in commercial markets. Based on the obtained results of biochemical analysis, the investigated EMPF (fresh) has 4.979 g/ 100 g carbohydrate using the traditional anthrone test. Additionally, the studied fresh EMPF has 2.413 g/ 100 g as a total protein content using the Folin-Ciocalteu test. Besides, FT-IR indicates the chemical existence of function groups of protein and carbohydrate in the investigated EMPF. The main contents of the cultivated EMPF are moisture followed by carbohydrates and protein in addition to traces from ash and metals. The antioxidant of the cultivated EMPF was evaluated via 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity values using different mushroom concentrations from 30 -150 g/L indicating that the optimum one is 90 g/L. The antimicrobial of the cultivated EMPF was tested and the results affirm the high performance of the EMPF as antibacterial or antifungal compared with familiar antibacterial or antifungal (Streptomycin or fluconazole, respectively). To conclude, this work introduces the antimicrobial and antioxidant of the studied EMPF.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"43 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139126943","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}

Patulin forms an adduct when it interacts with amino acids that contain thiol groups; the creation of these adducts could represent the main toxic pathway of PAT. Catechins are a major component of green tea polyphenols. Polyphenols have many protective effects against chronic diseases. In this study, 60 rats were randomly divided into five groups, with 12 rats in each group. Group I rats were given 0.1% DMSO in saline 2 mL/kg BW for 7 days; Group II rats received 50 mg/kg BW of GTE for 7 days; Group III, IV, and V rats received 0.2 mg/kg BW of patulin for 14 days; then Group IV and V rats received 50 mg/kg and 100 mg/kg BW of GTE for 7 days; respectively. We evaluated the nephrotoxicity induced by patulin within the medulla and cortex and the enhancement role of GTE on both renal histological and physiological parameters. Urea, BUN, and creatinine levels showed a high significance increase ( p <0.001) in the patulin group, while GTE-treated groups showed a high significance decrease ( p <0.001). PAT-induced harmful effects on kidney tissue are portrayed in the structure of the cortex and medulla. The cortex showed improvement in renal corpuscles, while the medulla showed highly dilated lumina in most tubules with luminal deposits. Treated groups with GTE showed improvement in renal corpuscles, especially with high doses. So, we concluded that GTE had dose-dependent antioxidant and therapeutic effects on renal functions.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139129274","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}

In this work, we aimed to prepare, characterize, and investigate some unprecedented hybrid compounds comprising carboxamide and 1,3,4-thiadiazole in addition to 1,3,4-thiadiazine motifs synthesized from thioxoacetamide derivatives. Here, thioxoacetamide derivatives are used as building blocks in the preparation process of these compounds. Moreover, the reaction of thioxoacetamide was examined with some reagents having electrophilic centers such as ethyl chloroformate, phenyl isothiocyanate, triethylorthoformate, malononitrile and diethyl-2-(bis(methylthio)methylene) malonate, to give five-membered heterocyclic rings, also reacted with ethyl chloroacetate, and chloroacetonitrile and the resulting products are six-membered heterocyclic rings. The synthesized compounds were characterized and investigated their validity by full spectral analysis. According to previous studies, these compounds are expected to have high biological activity in various antidotes.","PeriodicalId":146413,"journal":{"name":"Sohag Journal of Sciences","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122763565","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}
