Lentiviral vector induces high-quality memory T cells via dendritic cells transduction.

immunization favored effector memory phenotype. Studies using HIV antigens in outbred rats demonstrated additional clear-cut evidence for an immunogenic advantage of lentiviral vector over Ad5. Additionally, ...

Assessment of hazards and risks associated with dietary exposure to mineral oil for the Belgian population

Belgian population. For MOSH, the no observed adverse effect level (NOAEL) value of 19 mg kg−1 bw day−1 based on the hepatic inflammation-associated granulomas found in a 90-day oral study in F-344 rats was ...

Update of the risk assessment of nickel in food and drinking water

chronic and acute dietary exposure. An increased incidence of post‐implantation loss in rats was identified as the critical effect for the risk characterisation of chronic oral exposure and a BMDL10  of ...

Risk assessment of ochratoxin A in food

characterisation of neoplastic effects, a BMDL10  of 14.5 μg/kg bw per day was calculated from kidney tumours seen in rats. The estimation of chronic dietary exposure resulted in mean and 95th percentile levels ...

Risk assessment of chlorinated paraffins in feed and food

as the target organ. The Panel selected as reference points a BMDL10  of 2.3 mg/kg bw per day for increased incidence of nephritis in male rats, and of 36 mg/kg bw per day for increased relative kidney ...

Risk assessment of aflatoxins in food

0.4 lg/kg body weight (bw) per day for the incidence of HCC in male rats following AFB1 exposure to be used in a margin of exposure (MOE) approach. The calculation of a BMDL from the human data was not ...

In Vitro and In Vivo Toxicity Studies on Cymbopogon giganteus Chiov. Leaves Essential Oil from Benin

Mutagenic potential was assessed by the Ames test using Salmonella typhimurium strains TA98 and TA100. Oral acute toxicity was carried out by administration of a single dose of 2000 mg/kg b.w. to Wistar rats ...

In vitro antigenotoxic activity, in silico ADME prediction and protective effects against aflatoxin B1 induced hepatotoxicity in rats of an Erythrina latissima stem bark extract

rats induced by the same agent. Male Wistar rats were orally treated with ELBE (20 mg/kg, 50 mg/kg and 100 mg/kg) or curcumin (500 mg/kg) combined with piperine (20 mg/kg) — positive control, for 8 days ...
