What is the affect of doping on XRD peak intensity?
Yes, there will be shifting of XRD peaks during doping. The main reason in your case is the increase/decrease in the lattice parameters that is reflected by the shift of diffraction peaks. This effect is mainly due to the difference in ionic radii between the main element and the dopant ion.
What is blood doping?
Blood doping is the practice of misusing certain techniques and substances to increase the red blood cells in the body. There are three widely known substances or methods used for blood doping, namely, erythropoietin (EPO), synthetic oxygen carriers and blood transfusions*.

Withdrawal from anabolic steroid use can be associated with depression, and in some cases, suicide.
How does exercise affect the body?
In the human body, exercise can be a source profound physiological changes. In particular, its impacts the release of fundamental hormones in the body. The adrenal glands is the body 's main site of steroid hormone release and it responds to increased physical activity through the release of hormones such as cortisol and aldosterone. (Buono & Yeager, 1991) Aldosterone is an essential hormone used by the body to maintain sodium and fluid balance. It exerts it effects by increasing sodium re-absorption and potassium secretion in the kidneys and in turn this also increases water resorption.
Why is the pressure in the arteries higher?
So in the arteries of the human being, if its pathway is blocked by fatty deposits, the walls becomes smaller and the heart has to pump a higher amount of pressure to get the blood flowing through, resulting in hypertension. In order to check if a patient is suffering from hypertension or abnormal levels of blood pressure, there are four indirect and non-invasive methods to assess the patient.

Is blood doping the same as EPO?
Blood doping has the same end result as using EPO. In effect, the athlete donates a unit (about a pint) or two of blood to himself. The blood can be stored for a month or two while the body replenishes it and just before competition, the saved blood is transfused back into the athlete, increasing the red blood cell count and the oxygen delivery capacity. The risk? The same as using EPO – blood clots and potential death.
What is blood doping?
According to the World Anti-Doping Agency (Wada) blood doping is defined as the “misuse of certain techniques and/or substances to increase one’s red blood cell mass, which allows the body to transport more oxygen to muscles and therefore increase stamina and performance”.
What are the most common methods of blood doping?
There are three most commonly used methods for blood doping and these include erythropoietin (EPO), synthetic oxygen carriers and blood transfusions, all of which are prohibited under Wada’s List of Prohibited Substances and Methods.
What does EPO do to your body?
EPO is a naturally occurring hormone that stimulates bone marrow to up your red blood cell count. Simply put, more red blood cells means more oxygen traveling to muscles. Pro athletes may be able to dose themselves precisely, with small amounts every day, but if you take too much EPO you end up with too many red blood cells, which actually thicken the blood and slow it down in your veins.
Does hematocrit increase risk of stroke?
The same blood-thickening effect also increases the risk for blood clots, stroke and heart attack. “The most dangerous side effect relates to an increased risk of a thromboembolic event (clot),” says Amit Momaya a surgeon at the University of Alabama at Birmingham. The cellular components of the blood, or “hematocrit,” usually make up about 40 percent of blood volume when centrifuged. As red blood cells accrue, hematocrit goes up as well and along with it, the risk of blood clots and heart attacks.
Does EPO cause cancer?
As a growth hormone, EPO also has antiapoptotic effects, meaning that it slows down the body’s natural system of killing and removing damaged cells. “It doesn’t cause cancer, but it might prevent the body from killing cancer cells, or it might aggravate growth of cancer cells,” says Franz. Some long-term studies of kidney patients have found an increased incidence of cancer for those treated with EPO, and experts hypothesize that the hormone may stimulate tumor growth.
Can EPO cause blood clots?
In 2014, researchers in The Netherlands noted that four recent trials of kidney transplant patients receiving high doses of EPO after surgery found an increased risk of blood clots. “EPO is known to induce hypertension, so if you are a more mature male you might already have hypertension and taking EPO could have long-term risks,” says doctor Stefan Franz.
What is doping misconduct?
Likewise, doping includes other forms of misconduct, such as assisting, encouraging, provoking, inciting or covering up an anti-doping rules violation or any attempted violation either by an athlete or a member of their team, such as their doctor or physical trainer.
