	Le Magazine, July 2004 - Report: Cortisol
		Cortisol is one of several hormones in the hypothalamic-pituitary-adrenal axis.
		Cortisol has short-term anti-inflammatory properties, which is why it was used to treat arthritis when first made available as a drug in the 1950s.
		Cortisol also enhances the expression of the 5-lipoxygenase (5-LOX) enzyme, which is the central enzyme responsible for synthesis of the inflammatory leukotrienes involved in neurodegeneration.

	Biomarker Network - Collection
		Cortisol is a steroid hormone produced by the adrenal cortex.
		As a stress induced hormone, cortisol secretion to an immediate challenge is a healthy response, while consistently high cortisol reactivity to repeated familiar challenges is an atypical response that may reflect chronic physiological stress (Epel et al., 2000) and is associated with negative health outcomes in old age (Seeman et al., 1997).
		Cortisol levels have been shown to be greater among individuals experiencing chronic stress from work or emotional strain (Steptoe et al., 2000).

	Bodybuilding.com - David Robson - The Implications Of Cortisol Release!
		Cortisol is termed catabolic as it has the opposite effect to testosterone, insulin and growth hormone in that it breaks down tissue.
		In fact cortisol, which is released by the adrenal glands under conditions of high mental and physical stress and high temperature, is the bodyâ€™s primary catabolic hormone.
		Cortisol is at its lowest and growth hormone is at its highest during slow wave sleep (deepest stage of sleep).

	Dr. Perricone on Stress and Cortisol
		Cortisol is essential in our bodies to maintain homeostasis during acute forms of stress, such as fear, physical trauma and extreme physical exertion.
		Cortisol causes death to brain cells when it is circulating at a high level.
		It is not surprising that we in the anti-aging field call cortisol "the death hormone" because it is truly associated with old age and disease.

	Cortisol: The Test
		A cortisol test may be ordered when a patient has symptoms that suggest Cushing’s syndrome (obesity, muscle wasting, and muscle weakness) or Addison’s disease (weakness, fatigue, increased pigmentation, among others).
		Cortisol testing may be ordered at intervals when patients are being or have been treated for Cushing’s syndrome or Addison’s disease to monitor the effectiveness of treatment.
		Salivary cortisol testing is being used more frequently to help diagnose Cushing's syndrome and stress-related disorders but still requires specialized expertise to perform and is not yet widely available.

	Cortisol - lose weight with Cortislim
		Cortisol is produced in the adrenal glands of the body.
		Cortisol is its main secretion, even as the adrenal cortex also produces aldosterone (in the zona glomerulosa) and some sex hormones (in the zona reticulosa).
		The functions of cortisol include assistance in the regulation of blood pressure and cardiovascular function, besides regulation of the use of proteins, carbohydrates, and fats in the human body.

	MedlinePlus Medical Encyclopedia: Cortisol level
		A cortisol level is a blood test that measures the amount of cortisol, a steroid hormone produced by the adrenal cortex.
		Cortisol levels are often measured to evaluate the pituitary and adrenal function.
		Cortisol is a steroid hormone released from the adrenal cortex in response to a hormone called ACTH (produced by the pituitary gland).

	Cortisol - Wikipedia, the free encyclopedia
		Cortisol is a corticosteroid hormone produced by the adrenal cortex that is involved in the response to stress; it increases blood pressure, blood sugar levels, may cause infertility in women, and suppresses the immune system.
		The amount of cortisol present in the serum undergoes diurnal variation, with the highest levels present in the early morning, and lower levels in the evening, several hours after the onset of sleep.
		Changed patterns of serum cortisol levels have been observed in connection with abnormal ACTH levels, clinical depression, psychological stress, and such physiological stressors as hypoglycemia, illness, fever, trauma, surgery, fear, pain, physical exertion or extremes of temperature.

	Cortisol reviews
		Cortisol has a pivotal role in physical and mental health, but relatively few studies have paid attention to individual differences in cortisol levels and the etiology of these differences, in particular their possible genetic basis.
		Cortisol, while associated with fear and stress response, is also the hormone of energy metabolism and it coordinates behavioral adaptation to the environmental and internal conditions through the regulation of many neurotransmitters and neural circuits.
		Baseline cortisol levels were decreased in 98% of patients, ACTH hormone levels were increased in 96% of patients, and the cosyntropin stimulation test was positive in 100% of patients tested.

		Mean (SE) salivary cortisol concentration was 4.7 (0.5) nmol/l on awakening, peaked at 8.6 (0.9) nmol/l 30 min later, and declined to a trough of 2.3 (0.2) nmol/l 600 min after awakening.
		Mean resting cortisol concentrations for these samples were in the high end of the normal reference interval previously reported for this population in the literature: SER (656.5+/-122.3 nmol x L(-1)).
		METHODS: Salivary cortisol levels of 104 patients with metastatic breast cancer were assessed at study entry at 0800, 1200, 1700, and 2100 hours on each of 3 consecutive days, and the slope of diurnal cortisol variation was calculated using a regression of log-transformed cortisol concentrations on sample collection time.

	cortisol. The Columbia Encyclopedia, Sixth Edition. 2001-05
		A main effect of cortisol is to reduce the reserves of protein in all body cells except cells of the liver and gastrointestinal tract.
		Cortisol is synthesized and secreted by the adrenal cortex in response to the stimulating substance adrenocorticotropic hormone (ACTH).
		Cortisol, usually referred to as hydrocortisone when used medicinally, is more potent than cortisone with respect to metabolic and anti-inflammatory effects.

	Cortisol Tests Information on Healthline
		This test is a measure of serum cortisol (also known as hydrocortisone), or urine cortisol (also known as urinary free cortisol), an important hormone produced by a pair of endocrine glands called the adrenal glands.
		Blood and urine cortisol, together with the determination of adrenocorticotropic hormone (ACTH), are the three most important tests in the investigation of Cushing's syndrome (caused by an overproduction of cortisol) and Addison's disease (caused by the underproduction of cortisol).
		Cortisol is a potent hormone known as a glucocorticoid that affects the metabolism of carbohydrates, proteins, and fats, but especially glucose.

	University of Chicago Hospitals: Low levels of salivary cortisol associated with aggressive behavior
		Consistently low salivary levels of the stress hormone cortisol in boys aged 7 to 12 are associated with early onset and persistence of extremely aggressive behavior report researchers from the University of Chicago in the Archives of General Psychiatry.
		More than one third of boys with low cortisol were nominated by their peers as the "meanest" in the class, compared with 10.5 percent of boys who had at least one higher cortisol reading.
		Although the mechanism connecting cortisol levels to aggressive behavior is unclear, McBurnett suspects that variation in levels may serve as a marker for abnormalities in the production of various stress hormones that influence the body's response to a challenge or confrontation.

	Cortisol - Is NOT a Nasty Little Hormone
		Cortisol is a steroid hormone made in the adrenal glands, which are small glands adjacent to the kidneys.
		Cortisol is released in the body during stress; hence is called the "stress hormone." But cortisol is more than a simple marker of stress levels - it is necessary for the function of almost every part of the body.
		Cortisol releases glucose and amino acids for cellular energy and is associated with the "fight or flight" response.

	Cortisol and Labored Breathing
		If the sudden elevation of cortisol had caused the death, as was the case in examples mentioned before, then cortisol is not only the hormone of aging but also the "angel of death".
		In an article titled "Cortisol" by Jodi Tuck, she states, "Cortisol is a steroid hormone that is released from the zona fasciculata of the adrenal cortex in response to stress.
		Measurement of cortisol in a repeated public-speaking challenge has revealed individuals who do not habituate, and these individuals, who lack self-confidence and self-esteem, are undoubtedly overexposing their bodies to stress hormones under many circumstances in daily life that do not overtly disturb other individuals.

		Cortisol secretion is usually very low at this time of the day, but in patients with Cushing's syndrome, the value is virtually always elevated.
		Although the majority of patients with Cushing's have elevated levels of urine free cortisol, it is becoming increasingly evident that many patients with mild Cushing's syndrome will actually have normal levels of urine free cortisol.
		Some patients with Cushing's syndrome may have a tumor in their adrenal glands secreting excessive cortisol or occasionally may have nodules in both adrenal glands that are hypersecreting.

	Muscle Breakdown: Is Cortisol Leading You Down the Catabolic Pathway? by Rehan Jalali
		Another one of cortisol's undesirable effects for athletes is it causes insulin resistance by decreasing the rate at which insulin activates the glucose uptake system, likely because of a post-insulin receptor block (2).
		Cortisol suppression may be an essential part in the recovery process for athletes involved in a rigorous training program.
		Decreasing cortisol levels or suppression of cortisol production is not desired in many instances as it may cause adverse effects such as a decrease in reaction time to wounds and healing mechanisms in the body.
