Low Free Testosterone Predicts Mortality from Cardiovascular Disease But Not Other Caus... - 0 views

  •  
    low free Testosterone found to be associated with decreased CVD.

Sex Hormone-Binding Globulin and Insulin-Like Growth Factor-Binding Protein-1 as Indica... - 0 views

  •  
    SHBG decreased in hyperinsulinemic states, such as in metabolic syndrome.  Low Testosterone has proven to be the same, though not looked at in this study.   Also, in this study, low SHBG is associated with increased cardiovascular mortality.

Regulation of production and secretion of sex hormone-binding globulin in HepG2 cell cu... - 0 views

  •  
    SHBG and hormones.  Insulin, IGF-1, and EGF decrease SHBG levels.  Contrast that with estradiol, testosterone, T3, and cortisol that increase SHBG

Low Grade Chronic Inflammation in Women with Polycystic Ovarian Syndrome - 0 views

  •  
    low grade, chronic inflammation associated with PCOS and common disease states associated with PCOS.  It is known that high androgen levels in women causes inflammation.

Vitamin D, Mitochondria, and Muscle - 0 views

  •  
    editorial discussion of the benefit of vitamin D in mitochondrial function.   Those in the vitamin D repletion arm of the study had a quicker recovery time to restored phospho-creatinine levels.  The quicker the recovery of phospho-creatinine levels, the shorter recovery phase and the likely improvement in athletic performance.

Improving the Vitamin D Status of Vitamin D Deficient Adults Is Associated With Improve... - 0 views

  •  
    Fascinating link between vitamin D and mitochondria function in skeletal muscle.  Vitamin D replacement was found to improve mitochondrial function, improve post exercise discomfort in those with vitamin D deficiency.  Obviously, this provides support for a link between vitamin D and mitochondrial function.  This could provide an important tool in the recovery phase in athletes.

Sex Steroid Hormone Levels and Body Composition in Men - 0 views

  •  
    The results of this study: body composition i.e. fat, effects hormone levels, rather then hormone effecting body composition.

Diet and Sex Hormone-Binding Globulin - 0 views

  •  
    In men, flax intake is positively associated with SHBG; whereas protein intake is inversely associated with SHBG.

Production of 3α-Androstanediol Glucuronide in Human Genital Skin - 0 views

  •  
    DHT metabolite 3 alpha-androstanediol shown to be a good assessment of peripheral DHT action.

Differences in the Apparent Metabolic Clearance Rate of Testosterone in Young and Older... - 0 views

  •  
    Age seems to predict metabolism of testosterone in those receiving testosterone therapy.  Older men appear to have slower metabolism of testosterone.  This implies that one can likely dose "older" men at lower dosages.

Thyroid Hormone Action Is Disrupted by Bisphenol A as an Antagonist - 0 views

  •  
    Bisphenol A (BPA) shown to interfere with the T3 and thyroid hormone receptor interaction.  This study even showed that BPA inhibited thyroid receptor transcription.

Effects of Cortisol on Carbohydrate, Lipid, and Protein Metabolism: Studies of Acute Co... - 0 views

  •  
    This study they looked at the withdrawal of cortisol on glucose homeostasis.  The point is that cortisol has profound effects on glucose homeostasis.  Elevated cortisol or exogenous intake reduces T3 and increases insulin resistance.

Cardiac Involvement in Thyroid Hormone Resistance - 0 views

  •  
    Thyroid hormone resistance has cardiac effects.

Thyrotropin Suppression by Metformin - 0 views

  •  
    Metformin shown to suppress TSH secretion without change in free t4 or free t3 levels.  This again, shows the lack of reliability of the test TSH.  With the suppression of TSH indicated in this study, the free t4 and t3 should have been elevated, but were obviously not.

Testosterone Treatment and Mortality in Men with Low Testosterone Levels - 0 views

  •  
    In this study, testosterone therapy in those with low T was found to provide a reduction in mortality compared to no testosterone therapy.

Persistent Subclinical Hypothyroidism and Cardiovascular Risk in the Elderly: The Cardi... - 0 views

  •  
    study finds no increased risk of CHD, HF, or CV death in subclinical hypothyroidism in older adults.  No insight is gained from this article, due to the use of TSH as the only tool for thyroid assessment.  TSH has been shown to become unreliable as a sole thyroid assessment tool an aging population.

Mortality and Other Important Diabetes-Related Outcomes With Insulin vs Other Antihyper... - 0 views

  •  
    Insulin therapy in people with type II diabetes shown to increase complications, cancer, and mortality.  The reason?  Insulin is not the problem.  Treat the cause.  Diabetes can not be properly managed without dietary changes and weight loss.
