Researchers from the Hangzhou Medical College School of Public Health, China, disclosed the results of their latest study. According to their research, women with increased levels of triclosan in their urine were more probable to have issues with their bones, as compared with those having low levels. If believed to Yingjun Li, lead author of this study, earlier researchers have already demonstrated that triclosan might have the ability to adversely impact the bone mineral density in cell lines and animals. However, there is very little known regarding the impact of the chemical on human bone health.
Yingjun Li proclaimed that this is the foremost epidemiological research to investigate the link between triclosan contact with bone mineral density and osteoporosis in a nationwide representative model from the U.S. adult women. Triclosan can be described as an antibacterial chemical widely employed in personal hygiene products such as toothpaste, soaps, mouthwash, and hand sanitizers.
On a similar note, the capability to program living cells to behave in particular ways under certain conditions is creating novel opportunities in medicine. A recent mouse study in which researchers programmed bacteria to help fight cancer can be considered as an example. Researchers reprogrammed bacteria and employed them in the battle against cancer.
A few tumors thrive and expand as their cells send out a “don’t eat me” signal. This signal makes an individual’s immune system leave them. Tumor cells that are not sending the signal are exposed to macrophages and other immune cells, which engulf and digest them. Recently, researchers from Columbia University, New York, demonstrated the possibility to program bacteria to stop the “don’t eat me” signal and stimulate an anti-tumor immune response. The latest approach is said to be a model of synthetic biology, which is said to be an emerging field where medical treatments are more effective and precise than many molecular techniques.
