A Dynamic Duo: When to Test Neurotransmitters with Sex Hormones

The nervous system and its communication with peripheral organs is under the continuous dynamic influence of hormones, neuroactive steroids, and neurotransmitters. This is why the underlying pathology of mood disorders can often be varied and complex.

The hormonal piece is critical to our understanding of the imbalances when it comes to the complete neurotransmitter assessment. Hormones regulate key processes pertaining to neurotransmitter biosynthesis, signaling, and degradation. It is important to recognize that disturbances in the relationships between hormones and neurotransmitters can shape normal physiology toward a maladaptive state leading to suboptimal psychological wellbeing.

Neurotransmitters 101

The brain orchestrates the delicate interplay between the body and the mind. Structural brain units, the neurons, discharge neurotransmitters. These neurotransmitters provide a communication platform for the brain to fuel internal systems with information. Anything the body senses, feels, hears, smells, touches, or ingests serves as an input that prompts an astoundingly fast response. In the central and peripheral nervous system, neurotransmitters operate as chemical messengers that relay the signal and receive feedback via electrochemical impulses to regulate cognition, memory, emotions, respiration, heart rate and contractility, digestion, metabolism, blood flow and pressure, and hormonal responses. When released from peripheral organs, neurotransmitters can also behave as hormones by diffusing to distant sites via the circulation.

Element Testing – Why Sample Type Matters!

Posted by Ted Zava on Tuesday, 03 May

Urine, serum, plasma, whole blood, red blood cells, feces, hair, fingernails … the list goes on. How do you decide what biological sample(s) to use for element analysis? Can results be compared to scientific literature or do they have clinical significance? Is it possible for values to be elevated or low in one sample type and normal in another? Do test results indicate recent intake, body burden, acute toxicity, chronic toxicity, deficiency, or homeostatic regulation? These are just some of the questions facing a testing laboratory when they want to develop and validate essential and toxic element profiles that will provide clinically meaningful results.

High Air Levels of Arsenic & Cadmium May Be Linked to a Cancer Cluster in Portland, Oregon

Many residents were surprised to learn today that high levels of arsenic and cadmium are being detected at an air monitoring station in Southeast Portland, Oregon according to the state Department of Environmental Quality (DEQ)

Watch the News: Dr. Zava comments on toxin exposure in SE Portland

The state began monitoring air quality after moss samples taken from the area last October were found to be high in arsenic and cadmium. The results, which were only made public in the past few days, show cadmium at 49 times the acceptable level and arsenic at 159 times the acceptable level for air.

Of key concern is that the testing location is in an area populated with businesses, schools, and parks. It is not clear yet how long exposure has occurred or whether it is caused by a nearby glass blowing facility. As of this week, the glass blowing facility decided to cease use of arsenic and cadmium.
