The contribution of bioinformatics\u0000 tools and databases in these two fields has provided key elements, sometimes impossible to explain during early clinical phases. In this context, some computational approaches were used in this work to investigate the molecular weight distribution (MWD), allergenicity, toxicity profile, possible\u0000 biodegradation, persistence and bioaccumulation factor of four natural compounds. Results revealed that MWD indices of compound 2 and 3 were the best among the tested compounds. However, the route of administration of compound 1 could be considered the safest for rats, especially the oral,\u0000 intravenous and subcutaneous ways, in which LD50 values were the best, comparing to the other compounds. The two allergenicity tests revealed that the four phyto-compounds could be considered non-allergen agents and may not present any drug toxicity risks. Concerning cytotoxicity,\u0000 compound 4 exhibited the best cytotoxic effect among these compounds with a corresponding value of Pa = 0.782 against colon carcinoma (HCT-116) cell line. The four bio-compounds could be toxic for avian species but non-toxic for Daphnia magna, a key aquatic species. Compound 1 exhibited\u0000 the lowest bioaccumulation factor value (0.17). All compounds were inactive against Tox21-Stress response pathways, but compound 2 and 3 could potentially be immunotoxic. Finally, all tested compounds may possess a non persistent profile, while only compound 1 and 4 could possibly be biodegradable.\u0000 This preliminary work, revealed once again the potential of phyto-compounds and certain fundamental aspects, which could represents an initial step for further investigation.","PeriodicalId":15157,"journal":{"name":"Journal of Biobased Materials and Bioenergy","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44358679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soil can be contaminated by heavy metals, organic chemicals like biological pathogens, pesticides, micro plastics and nano particles. Contamination decreases the soil’s capability\u0000 to yield food thereby affecting food production by means of pollution and disease. Moreover, soil contaminants move into rivers damaging the water quality. Numerous technologies have been established to tackle water and soil remediation, such as deep excavation technique where transportation\u0000 of contaminated soils or water is done to remote unpopulated sites. Recent development in Remote Sensing and geographic information processing techniques have led to exciting new opportunities for investigating and closely monitoring environmental factors that influence key land and soil management\u0000 approaches. Hence, this paper uses the Deep Excavation and Remote Sensing based Assessment Model (DERSAM) to assess the soil and water pollution in contaminated areas. The data are taken from the Europe soil contamination map to classify the contaminated and non-contaminated areas. This data\u0000 obtained from the high-resolution satellite of Remote Sensing (RS) technique and Geographical Information System (GIS) with the parallel expansion of a fully assimilated geospatial database system that provides monitoring and feedback at suitable spatial scales. Thus, such data can be utilized\u0000 for long-term environmental management and monitoring of remediation and rehabilitation of excavation areas. The numerical outcomes show that the recommended DERSAM model increases the land use and land cover change prediction by 90.2%, the classification ratio by 98.2%, the pollution reduction\u0000 ratio by 96.6%, the soil contamination detection ratio by 95.9%, and the overall performance by 97.2% compared to other existing approaches.","PeriodicalId":15157,"journal":{"name":"Journal of Biobased Materials and Bioenergy","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41391888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to evaluate the toxicity profile\u0000 of this plant, rats were orally treated with a single concentration of 2000 mg/kg and observed during a period of two weeks. For the anti-diabetic study, thirty male wistar rats (130–170 g) were randomized into 5 groups (n = 6/group). Groups I and II served as negative and normal\u0000 controls, respectively. Diabetes was induced in test groups (II–V) using 200 mg/kg of body weight (BW) streptozotocin. Concerning the clincial outcomes, no mortality, morbidity, or abnormal hematological, biochemical and histopathological alterations were observed. Accordingly, J.\u0000 regia L is considered a non-toxic plant. The extract was found to limit weight loss and reduce blood glucose levels by −32.30% after 14 days of treatment for the anti-diabetic and anti-atherogenic study.
