Tsc-22 is a novel tumor suppressor gene that represents a new class of transcription factors that has transcriptional repressor activity. We found Tsc-22 downregulation in livers from B6C3F1 mice following treatment for 2 weeks with carcinogenic doses of the antianxiety drug oxazepam (2500 ppm) or the peroxisome proliferator Wyeth-14,643 (500 ppm) but not with two other carcinogens such as o-ni...

Introduction For most countries it is currently unknown to what degree concentrations of psychotropic drugs in surface water exceed environmental threshold (ETCs) [MOU1] for ecosystems and risk mitigation could be applied. ETCs are defined as per-compound above which detrimental effects on reproduction, growth, mortality aquatic organisms cannot exclude Objectives To quantify levels antidepress...

The carcinogenicity of benzodiazepines (BZDs) is still unclear. We aimed to assess whether long-term benzodiazepines use is risk for cancer.We conducted a longitudinal population-based case-control study by using 12 years from Taiwan National Health Insurance database and investigated the association between BZDs use and cancer risk of people aged over 20 years. During the study period, 42,500 ...

OBJECTIVES This study investigated and quantified risk factors of dose escalation, as an indication of drug misuse and dependency of benzodiazepines and congeners, among presumably drug naïve patients in the Norwegian drug prescription database, observed over 3 years. DESIGN Observational study. SETTING Prescription database study. PARTICIPANTS We defined an excessive user as one redeemin...

Migration is an important life-history event in a wide range of taxa, yet many migrations are influenced by anthropogenic change. Although migration dynamics are extensively studied, the potential effects of environmental contaminants on migratory physiology are poorly understood. In this study we show that an anxiolytic drug in water can promote downward migratory behaviour of Atlantic salmon ...
