The study of vascular modulation has received a great deal of attention in recent years. Here we present the generation of a novel structural biomarker, which can be incorporated into a number of contemporary image analysis platforms and used to compare tumour versus systemic host tissue vascularity. By contrasting the measurements obtained, the preclinical efficacy of vascular modulating chemotherapies can be evaluated in light of concomitant systemic vascular toxicity.

The aim of this study was to estimate the lower limit of the benchmark dose (BMDL) as the threshold limit level of the Cd concentration in rice for itai-itai disease and/or suspected disease based upon a logistic regression model. The estimated BMDLs of the Cd concentration in rice for itai-itai disease and/or suspected disease were 0.62–0.76 and 0.27–0.56 mg kg−1 in men and women, respectively. This result provides important information about the worldwide standard for the Cd concentration in rice.

Perinatal exposure to xeno-oestrogens can disrupt female sexual development, leading to changes in reproductive behaviour in adulthood, but the effects remain to be fully determined. We examined the effects of a single perinatal exposure to low (0.02 mg kg−1) and high (2.0 mg kg−1) doses of 17α-ethinyloestradiol (EE) on female rats in a paced mating test. The high EE dose, but not the low dose, disrupted females' sexual behaviours in adulthood. Such exposure could pose a risk to reproductive health.
- Role of connexin 43 in cadmium-induced proliferation of human prostate epithelial cells

The roles of the protein connexin 43 (Cx43) in the effects of Cd on the prostate have not been reported previously. In this study, the human prostate epithelial cell line RWPE-1 was exposed to Cd. A low dose of Cd stimulated cell proliferation, along with a lower degree of gap junction intercellular communication and an elevated level of Cx43. Knockdown of Cx43 blocked Cd-induced proliferation. Thus, Cx43 might be a target for prostatic abnormality associated with Cd exposure.
- Pancreatic impairment and Igf2 hypermethylation induced by developmental exposure to bisphenol A can be counteracted by maternal folate supplementation

Perinatal BPA exposure can induced epigenetic modification in offspring islet. Maternal folate supplementation can ameliorate perinatal BPA-induced glucose intolerance and β-cell dysfunction in the offspring. Perinatal BPA exposure induced DNA hypermethylation of Igf2 in offspring islets which can be counteracted by maternal folate supplementation. The changes of epigenetics in islet may contribute to the protection.
