Discuss what we consider as extreme conditions for biochemical parameters.
Discuss different extreme or extraordinary conditions that influence precise biological aspects. Identify what and how biochemical parameters may influence clinical follow-up.
Discuss what we consider normal range and critical values influenced by environmental and extreme activities. Identify the consequences of intermittent hypoxemia in the patient with long standing obstructive sleep apnea. Explain the effects acute exposure to intermittent hypoxia molecular, physiological in otherwise healthy young adults.
Assess the implications of the above findings to the high altitude workers who travel from sea level to high altitude for work.
We will discuss this possibility first by discussing the most thoroughly documented effects of nocturnal intermittent hypoxemia in the patient with long standing obstructive sleep apnea.
Then we consider the consequences of intermittent hypoxemia in otherwise healthy young adult humans, and finally conjecture on how these results might apply to the high altitude worker and what to do about it. The intermittent hypoxemia attending severe obstructive sleep apnea has been well documented to produce oxidative stress, sensitization of carotid chemoreceptor output and marked reductions in endothelium-dependent vasodilation, leading to persistent daytime elevations in sympathetic vasomotor outflow and systemic hypertension.
In healthy young awake adult humans brief periods of daily hypoxic exposure have not elicited adverse cardiovascular after-effects. On the other hand, recent studies mimicking the intermittent hypoxemia of sleep apnea in healthy subjects for up to two weeks shows persistent daytime elevations in muscle sympathetic nerve activity MSNAimpaired vascular vasodilation and moderate elevations in systemic blood pressure.
In summary, given our current questioning of both the benefits to performance and the cardiovascular risks of prolonged intermittent hypoxemia, it seems important to determine for each worker when the risks might exceed the benefits.
We address the problem of cardiovascular consequences of intermittent hypoxemia as experienced clinically in severe obstructive sleep apnea and in healthy adults and the implications of these findings to the high altitude workers who travel from sea level to high altitude for work. At the end of this session, participants will be able to: Review the impact of chronic and intense exercise on physiological responses and on biomarkers in humans.
Identify the changes in biochemistry parameters associated with the marathon and ironman challenges. Present the impact of training and conditioning on those responses. Chronic regular exercise provides significant benefits on cardiovascular, cardio-metabolic, and overall health.
Moreover chronic exercise decreases the circulating markers of inflammation. Despite the benefits related to the practice of regular exercise, strenuous and intense exercise such as the marathon or Ironman may cause some structural changes to the myocardium.
In fact, some studies have reported elevation in cardiac markers such has BNP, Troponin, IL-6, cardiac edema, as well as global left ventricular dysfunctions following strenuous long distance endurance exercise. In addition, some recent investigations have reported sub-clinical inflammation in athletes engage in high volume endurance exercise training.
Finally the life-long risk of atrial fibrillation increases with some sports such has running or cycling. The effects of intense aerobic training and competitive endurance exercise remain controversial. Intense and prolonged endurance exercise such as the marathon results in high cardiovascular strain whose clinical relevance, especially for middle age and older athletes is unclear and remains a matter of controversy.
There is a need for more investigations on the metabolic consequences of intense endurance exercise especially in amateur runners over the age of 35 years.The Speakers of DEF CON Speaker Index.

Here we take a much closer look at some current automation concepts and successes that increasingly incorporate A.I.-enabled robotics. Industrial robots and other automation machines are discussed along with some brief historical background for perspective.
If you answered yes, you were probably using a form of moral reasoning called "utilitarianism." Stripped down to its essentials, utilitarianism is a moral principle that holds that the morally right course of action in any situation is the one that produces the greatest balance of benefits over.
