The aim of the study was to evaluate the effect of CE exposure via gavage on metabolic and redox status in pregnant, lactating rats and their pups at weaning. The oral administration of this pesticide at doses of 1 mg/kg of body weight No Observed Adverse Effects Level (NOAEL), 5.4mg/kg b.wt (1/25LD50) and 13.5 mg/kg b.wt (1/10LD50) was given 1day/2 to female rats during the entire gestation and lactation period. Plasma biochemical parameters as well as lipid profiles and oxidative stress markers were determined. Oral CE exposure induced an increase in plasma glucose, urea, creatinine and lipid status levels in mothers at parturition (day 0) and at the end of lactation (day21) and in their offspring at weaning (day21). An altered oxidant/antioxidant status marked in mothers treated by the insecticide at day 0 and day 21 and these disturbances were also seen in their offspring. In conclusion, different doses CE exposure induced several metabolic and redox alterations leading to maternal physiological impairments and to offspring metabolic changes. CE should be used with caution especially during pregnancy and lactation period.","PeriodicalId":286353,"journal":{"name":"Journal of Natural Product Research and Applications","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121536346","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}

Phytochemical tests, total phenolic, flavonoid and tannins contents of the different aqueous extracts were determined. DPPH radical scavenging assay and Ferric Reducing Antioxidant Power (FRAP) were employed for the evaluation of the antioxidant activity. Whereas, the antihemolytic activity was carried out by the evaluation of the protective effect of the various prepared extracts on red blood cells against the radical attack induced by 2,2′-azobis(2-amidinopropane) di-hydrochloride (AAPH). The aqueous extract of Globularia alypum prepared by decoction showed the highest level of total phenolic contents (196.52± 10.76 µg GAE/mg Extract). These findings confirmed the remarkably antioxidant properties of this plant with DPPH scavenging activity and FRAP test. A concentration of 160 µg/ml of this extract showed a protective effect against hemolysis induced by AAPH radical. Hence, Zygophyllum album extracts demonstrated lower level of total phenolic contents (30.41 ± 2.01 µg GAE/mg Extract) and lower antioxidant and antihemolytic activities. Globularia alypum extracts presented a powerful antioxidant and antihemolytic activities especially for the decoction extract whereas Zygophyllum album revealed a weaker protective effect except its maceration extract.","PeriodicalId":286353,"journal":{"name":"Journal of Natural Product Research and Applications","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132418780","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}

Food and energy intakes were also evaluated. The cafeteria diet led to higher energy intake, body weight, hyperglycemia and hyperlipidemia (higher TC, LDL-C and TG) in dams’ rats and their pups. Plasma vitamin C, Erythrocyte GSH levels and catalase activity were lower, whereas plasma diene conjugates (DC), Malondialdehyde and protein carbonyl levels (PC) in plasma and erythrocytes were higher in cafeteria-diet-fed mothers and their pups compared to controls. Supplement of linseed oil significantly enhanced plasma antioxidant defense capacities, as evaluated by the marked increase in the levels of plasma vitamin C and erythrocyte GSH as well as the activities of CAT and the significant reduction in lipid peroxidation (lower DC and MDA) and PC in CAFL-diet-fed mothers and their offspring. Simultaneous intake of linseed oil also reduced body weight, plasma TG, TC and LDL-C contents in obese pregnant and lactating dams and their pups at day 30 and day 90. The flaxseed oil supplementation may prevent lipid peroxidation and metabolic disorders which might be helpful in preventing obesity complications in mothers during pregnancy and lactation and in their offspring.\u0000REFERENCES:Adeoye, O., Olawumi, J., Opeyemi, A., & Christiania, O.

Daily observation Data were collected from three field observation stations (Bani Malik, Stadium, Industrial activity), and treated in ArcGIS environment. According to the obtained results, in the year 2010, NOX varies between (25 – 62.99 ppb), with very important concentrations in the south of the study area, surrounding the industrial activities. While in the year 2018, the highest concentrations were between (25 – 30.99 ppb) in the north of the study area. the spatial distribution of SO2 was very important in the south of the study area, compared to the highest concentrations in the north in 2018. The spatial distribution of PM10 was between (153 – 173 µg/m3) in the south of the study area, in 2018 we noticed a decrease of the PM10 concentration, in the industrial area with values between (67 – 77 µg/m3).
