Endocrine-Disrupting Chemicals: What They Are & How To Avoid Them

As a hormone testing lab, ZRT understands the importance of a well-balanced endocrine system in maintaining overall health. Hormone balance is achieved through multiple feedback mechanisms, and when any part of the system is thrown out of whack by forces beyond its control, there is a knock-on effect on the rest of the body systems that are under endocrine control. Such forces can include extreme or chronic stress, or exposure to environmental toxins that enter the body through the air we breathe or in our diets. Substances in the environment that upset the endocrine system are known as endocrine-disrupting chemicals, or EDCs.

There have been some articles going around the medical news reporting on a new Danish study [1] suggesting that hormonal contraception might increase risk of depression, and that previous studies may not have highlighted this link because they did not include women who stopped taking their birth control as a result of depressive symptoms. This study got around that problem by including in their survey women who had been using birth control at any time during the previous 6 months. So what is the fuss all about?

Exercise – Good for What Ails your Brain

Posted by Margaret Groves on Wednesday, 17 August

As the 2016 Olympic games play out in Rio, you might be feeling inspired to get moving yourself. While some sports admittedly look pretty dangerous, and we cringe at the sight of a cyclist skidding into the curb on a wet road and landing on her head, there are others that simply make us marvel at the agility and strength of the human body. For me, when I watch those swimmers cutting through the water at tremendous speed, I just want to get into a pool and see if I could really try to swim faster myself.

We’ve probably all heard by now that “sitting is the new smoking,” and that our health suffers greatly from inactivity. The human body was meant to be in motion at least for an hour or two a day, and this is known to keep the cardiovascular system tuned up as well as preventing excessive weight gain. But did you know that exercise affects levels of neurotransmitters in the body and can actually help you prevent or overcome disorders such as depression?

Research Puts the "R" in ZRT

Posted by Margaret Groves on Friday, 15 April

I have to admit, I believe that "research" is one of those words that I think is often misused today.

I started my own career in a cancer research lab, continued it in a pharmaceutical company research lab, and then got into medical information research and scientific writing, which meant using a range of medical literature databases and complex searching strategies. My early research career was back in the days before we had personal computers, so many hours – in between tending to assays and experiments (as well as late in the evening) – were spent thumbing through the pages of massive volumes of Index Medicus, the print version of Medline, in various university libraries to find relevant publications.
