Pharmacokinetics of oral and intravenous cannabidiol and its antidepressant-like effects in chronic mild stress mouse model
Publication date: Available online 30 May 2019Source: Environmental Toxicology and PharmacologyAuthor(s): Chen Xu, Tanran Chang, Yaqi Du, Chaohui Yu, Xin Tan, Xiangdong LiAbstractCannabidiol (CBD) exhibits significant efficacy in mental and inflammatory diseases. Several studies have recently reported on the rapid antidepressant-like effects of CBD, suggesting that CBD is a potential anti-depressant or anti-stress drug. However, CBD is mainly administered orally or by inhalation with poor bioavailability, resulting in high costs. We aim to explore the efficacy of long-term periodic administration of CBD in chronic mild str...

Bioaccumulation of decabromodiphenyl ether affects the antioxidant system in the clam Mactra veneriformis
In this study, the clams Mactra veneriformis were exposed to 0.1, 1, and 10 μg/L BDE-209 for 7 days and then maintained in clean seawater for 3 days as the depuration. The bioaccumulation of BDE-209 and the effects on superoxide dismutase, catalase, and glutathione peroxidase were investigated. BDE-209 accumulation was concentration-dependent and decreased by 36%-52% after recovery. Malondialdehyde contents increased in a time- and dose-dependent manner. mRNA expression and activity of antioxidant enzymes changed with different patterns and recovered after depuration. These results suggested that antioxidant syst...

Hydrogen sulfide ameliorates disorders in the parafacial respiratory group region of neonatal rats caused by prenatal cigarette smoke exposure via an antioxidative effect
Publication date: Available online 4 March 2019Source: Environmental Toxicology and PharmacologyAuthor(s): Xiang Yan, Fusheng Zhao, Senfeng Zhang, Fang Lei, Wen Wang, Yu ZhengAbstractWe previously found that hydrogen sulfide (H2S) ameliorated the dysfunction of central chemoreception caused by prenatal cigarette smoke exposure (CSE). In the present study, we further explored whether the parafacial respiratory group (pFRG) is involved in the protection of central chemoreception by H2S against prenatal CSE-induced injury. We found that NaHS, a donor of H2S, restored the expression of Phox2b, which was downregulated by prenat...

Cathepsin B mediated scramblase activation triggers cytotoxicity and cell cycle arrest by andrographolide to overcome cellular resistance in cisplatin resistant human hepatocellular carcinoma HepG2 cells
Publication date: Available online 5 March 2019Source: Environmental Toxicology and PharmacologyAuthor(s): Kaustav Dutta Chowdhury, Avik Sarkar, Sujan Chatterjee, Debajyoti Patra, Dipanwita Sengupta, Soumi Banerjee, Pratip Chakraborty, Gobinda Chandra SadhukhanAbstractAndrographolide regimen in single or in combination with anticancer drugs is a promising new strategy to reverse chemoresistance in heaptocellular carcinoma. Apoptosis inducing factor (AIF) may regulate a complementary, cooperative or redundant pathway, along with caspase cascades. Despite these findings, mechanisms underlying caspase-dependent and-independen...

Nano-eco toxicity study of gold nanoparticles on less explored aquatic organism Moina macrocopa: enzymatic biomarkers and bioaccumulation perspective
Publication date: Available online 22 February 2019Source: Environmental Toxicology and PharmacologyAuthor(s): Hemant P. Borase, Abhijeet B. Muley, Satish V. Patil, Rekha S. SinghalAbstractIn the field of nanoecotoxicology, very few reports have focused on biochemical changes in non-target organisms after nanoexposure. A less explored aquatic non-target crustacean Moina macrocopa was used in the present study to analyze toxicity effects of gold nanoparticles (AuNPs), an emerging nanomaterial. AuNPs was fabricated using tannic acid and were of 29 ± 2 nm in size. The 48 h LC50 value of AuNP...
