New research published in the online open access journal BMC Genomics is the first to show that this chemical can affect the breasts' genomic profile.
Jose Russo and coworkers from the Fox Chase Cancer Center in Philadelphia, along with colleagues from the University of Alabama in Birmingham, US, fed lactating rats with butyl benzyl phthalate (BBP), which their offspring then absorbed via breast milk. The offspring ingested levels of chemical estimated to be nearly equivalent to the Environmental Protection Agency's safe dose limit of BBP for humans.
The researchers found that BBP had a transitory effect on certain characteristics of the female offspring of the rats, such as the ratio of uterine weight to body weight and the genetic profile of the mammary gland. Dr Russo stated: "We are the first to report that neonatal/prepubertal exposure to BBP induced modifications in the gene expression of the mammary tissue."
Although these effects wore off once exposure to BBP was removed, the subtle changes in the mammary gland may have an effect later in life.
BBP is widely used as a plasticizer, an additive used to soften polymers, and is found in household fittings such as pipes, vinyl floor tiles and carpet backing. This type of chemical is known to be an endocrine disruptor, which mimics the effect of hormones. Endocrine disruptors are known to damage wildlife and they have also been implicated in reduced sperm counts and neurological problems in humans.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
