If researchers were able to determine that cortisol decreases vitamin d receptors, is there an assay for the general public?

If researchers were able to determine that cortisol decreases vitamin d receptors, is there an assay for the general public?

Not scientific fact: What you're referring to is a blog post without any scientific documentation or substantiation. Doctors and scientists use facts and data, not blogs and pseudoscience. Don't waste your money. There is no assay available because none is needed. ...Read more

Receptor (Definition)

An organ, cell or molecule that accepts an outside signal and causes an internal change. Eyes receive light, touch receptors send messages to the brain when stimulated by pressure and estrogen receptors bind Estradiol causing responses of normal breast, ovary and uterus cells to rising and falling levels of the female steroid hormones. Most of the time "receptor" refers to one ...Read more

I learned that the cox 2 receptor is inhibited by nsaids, but how exactly does amitriptyline reduce pain?

I learned that the cox 2 receptor is inhibited by nsaids, but how exactly does amitriptyline reduce pain?

Not yet known: The exact mechanism of action is apparently not yet known but it just thought to be by the low doses of Amitriptyline being used blocking pain signals in the spinal cord by the increase of norepinephrine and serotonin into the spinal cord tracks that carry pain signals to the brain, best wishes. ...Read more

Why do people feel tired or energetic, and how does it work? Like is it only melatonin and its receptor?

Why do people feel tired or energetic, and how does it work? Like is it only melatonin and its receptor?

Myriad of reasons: Discovering the reason for a person being tired or fatigued is a complex process of medical detective work. Sometimes we get lucky and the answer falls right out such as low functioning thyroid or severe anemia. Other times it's a combination of several things. You appear to have at least a good possible reason based on your condition of hypopit- I doubt it's JUST melatonin. What's your doc say? ...Read more

Can you please help me to understand how buprenorphine works with your bodies receptors for pain control, not opiate addiction?

Can you please help me to understand how buprenorphine works with your bodies receptors for pain control, not opiate addiction?

Buprenorphine: Buprenorphine, as marketed as butrans, is a potent opiod analgesic medication with the analgesic effect coming from partial agonist activity at mu opioid receptors. It is also an antagonist at kappa opioid receoptors, an agonist at delta receptors, and a partial agonist at orl-1 (nociceptin) receptors. Its binding affinity to the mu recetors is very high, and overdose cannot be easily reversed. ...Read more

Which immune assay is best to measure inflammatory responses?

Which immune assay is best to measure inflammatory responses?

No great test: Acute inflammation: c-reactive protein; long-term inflammation: erythrocyte sedimentation rate. But a complete blood count with differential can also help. There are so many tests you need to see a doctor to have the appropriate test ordered. ...Read more

Is a rapid heartbeat caused by blocked ach receptors dangerous?

Depends: Certain drugs and venoms cause reversible or irreversible blockade of acetylcholine receptors. Some cause rapid heart rate. If you're receiving such a drug, it's under the supervision of a physician, so put your trust in that person. Whether the increased heart rate is injurious depends on the specifics of your health history and condition. ...Read more

Is there a benefit to chemotherapy in hormone receptor positive, node positive postmenopausal breast cancer?

Is there a benefit to chemotherapy in hormone receptor positive, node positive postmenopausal breast cancer?

Often: There is increasing data based on the oncotype DX test in women with 1-3 positive notes that shows that some women will not get much benefit from chemo and some will get a great deal. It can be useful in cases where a woman is reluctant to take chemo. This is done on tissue that has been already removed. Most oncologists believe that women who have multiple positive nodes should get chemotherapy. ...Read more

Can weight bering exercise change the pain receptor on the nervous system to a higher level, where you start of weak and then become strong?

Can weight bering exercise change the pain receptor on the nervous system to a higher level, where you start of weak and then become strong?

No, just its working: It's more likely that instead of altering your pain receptors, you're the exercises are actually making you stronger! over time, weight-bearing exercises will become easier as your muscles get bigger and/or toned in response to the increased workload! good for you! ...Read more
