The best initial screening test for Cushing's syndrome is the 24-hour urinary free cortisol measurement. 17 Although some authors 16 do not support screening for Cushing's syndrome in the absence of clinical signs or symptoms, other investigators recommend routine measurement of 24-hour urinary free cortisol levels in all patients with incidental adrenal masses. Additional evaluation with a dexamethasone suppression test is warranted if Cushing's syndrome is suspected, a patient has signs or symptoms of the syndrome or the results of the 24-hour urinary free cortisol measurement are equivocal.

Kidneys are the natural filters of our body. They perform various functions, including maintaining acid-base balance, regulating blood pressure, producing hormones and reabsorbing water, glucose and amino acids . The symptoms of kidney dysfunction are normally felt via other organs and systems consequently affected. Fatigue, joint and back pain, high blood sugar level and impotence are all symptoms of degenerative kidney health. Recent studies have shown that Cordyceps enhances the kidneys’ potential by increasing 17-hdroxy-corticosteroid and 17-ketosteroid levels (Zhu, J. et al. The Scientific Rediscovery of an Ancient Chinese Herbal Medicine: Cordyceps sinensis The Journal Of Alternative And Complementary Medicine [part 1]Volume 4, Number 3, 1998, pp. 289—303 [part 2] Volume 4, Number 4, 1998, pp. 429 - 457.). 

The TSH receptor is formed as one polypeptide chain and inserted into the thyroid cell plasma membrane. It undergoes a processing that is reminiscent of that occurring with insulin. A segment of 30 or more amino acids is cut out of the receptor at approximately residue 320, forming a two peptide structure with the chains held together by disulfide bonds. It is thought that both the intact and the processed receptor are functional. The processing of the receptor is thought to involve a matrix metalloprotease-like enzyme cleaving the 120 kDa precursor to form the heterodimeric receptor. Subsequently, reduction of the disulfide bonds by a protein disulfide isomerase may separate the two molecules and lead to shedding of the “alpha” subunit. It is an interesting concept that shedding of the alpha subunit might be intimately related to onset of autoimmunity against the TSH receptor. Shedding of the receptor is augmented by TSH stimulation of thyroid cells (58). The amino-terminal ectodomain of the human TSH receptor has been expressed on the surface of CHO cells as a glycosylphosphatidylinositol-anchored molecule. This material can be released from the cells and is biologically active in that it binds immunoglobulins from serum of patients with Graves’ disease, and displays saturable binding of TSH (46), indicating that all of the “immunologic information” related to production of antibodies resides in the extracellular portion of TSH-R.

Standardized rhodiola supplements have also been put to the test in physicians during two-week stretches on night duty and in students during final exams. These trials have confirmed the herb’s general anti-fatigue effect, showing that it improves tests of physical fitness, mental fatigue and neuromotor function under stress.
Many people who have tried rhodiolareport that they feel better while taking it. The experience is described in terms of a continuous sensation of physical and mental relief from stress, and anecdotally the effect appears to be most pronounced in people who typically respond to stress with anger or feelings of helplessness. Animal studies on rhodiola have given us some clues as to the neurochemical basis of these effects, such as its effects on the metabolism of the serotoninergic system, boosting brain levels of dopamine, acetylcholine, and norepinephrine. The evidence also seems to suggest that rhodiola  influences the synthesis, levels, and/or activity of endorphins and enkephalins, since blocking the receptors for some of these “feel-good” peptides negates some of  its effects.
