Bioassays with terrestrial and aquatic species as monitoring tools of hydrocarbon degradation [PDF]
, 2016 In this study chemical analyses and ecotoxicity tests were applied for the assessment of a heavily hydrocarbon-contaminated soil prior and after the application of a remediation procedure that consisted in the stimulation of soil autochthonous ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Molecular Oncology, EarlyView.Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Impact of cypermethrin on enzyme activities in the freshwater fish Cirrhinus mrigala (Hamilton) [PDF]
, 2008 Freshwater fish Cirrhinus mrigala were exposed to lethal concentration (5 µg/L) for 1, 2, 3 ,4 days and sublethal concentration (1 µg/L) for 1, 7, 14, 21 days of cypermethrin to examine the enzymes activity, in functionally three different tissues namely,

Is birthweight associated with total and aggressive/lethal prostate cancer risks? A systematic review and meta-analysis [PDF]
, 2016 BACKGROUND: It has been hypothesised that intrauterine exposures are important for subsequent prostate cancer risk. Prior epidemiological studies have used birthweight as a proxy of cumulative intrauterine exposures to test this hypothesis, but results ...
