Echinaforce Hotdrink versus Oseltamivir in Influenza: A randomized, double-blind, doubl... - 0 views

  •  
    new study finds Echinacea plus elderberry out performs Tamiflu in the treatment of early flu-like symptoms.  This study was fairly large for a head to head randomized study.  I love it when natural therapies out perform prescription meds.

Chronic Inflammation and Cytokines in the Tumor Microenvironment - 0 views

  •  
    Acute inflammation is a response to an alteration induced by a pathogen or a physical or chemical insult, which functions to eliminate the source of the damage and restore homeostasis to the affected tissue. However, chronic inflammation triggers cellular events that can promote malignant transformation of cells and carcinogenesis. Several inflammatory mediators, such as TNF-α, IL-6, TGF-β, and IL-10, have been shown to participate in both the initiation and progression of cancer. In this review, we explore the role of these cytokines in important events of carcinogenesis, such as their capacity to generate reactive oxygen and nitrogen species, their potential mutagenic effect, and their involvement in mechanisms for epithelial mesenchymal transition, angiogenesis, and metastasis. Finally, we will provide an in-depth analysis of the participation of these cytokines in two types of cancer attributable to chronic inflammatory disease: colitis-associated colorectal cancer and cholangiocarcinoma.

    Sex difference of gut flora has different metabolic effects from the same diet.  Could it all begin in the get?  Are gut flora sexist?  Of course not, but this study highlights the sex difference of the gut flora and the gender different effects.

Estrogens and Their Genotoxic Metabolites Are Increased in Obese Prepubertal Girls: The... - 0 views

  •  
    Obesity in young girls increases Estradiol production compared to thin young girls.  Obesity increased  the Estrogen metabolite 16lpha-OH-E1  and this positively correlated with IL-6.

Salivary Testosterone and a Trinucleotide (CAG) Length Polymorphism in the Androgen Rec... - 0 views

  • Testosterone correlated inversely with participant age (r = −0.39, p = 0.012) and positively with number of CAG repeats
  • transactivation potential of the AR appears to decline in graded relation to an increasing number of CAG repeats, which are distributed over a normative range of 11–37 and, in Caucasian populations, commonly average 21–22 repeats
  • When activated by androgens, ARs translocate to the cell nucleus, where they exert transcriptional control of androgen-dependent genes by binding to androgen response elements within gene regulatory sequences
  • ...10 more annotations...
  • some evidence suggests a high number of CAG repeats may be associated with cognitive aging
  • androgens (like other steroid hormones) promote or repress the expression of genes specifying an array of cellular proteins
  • diurnal variation in testosterone levels
  • salivary testosterone correlated negatively with participant age and positively with CAG length variation in the AR gene
  • CAG repeat number varied inversely with reactivity of the ventral amygdala to facial expressions of negative affect
  • higher salivary testosterone was likewise associated with a greater number of AR CAG repeats
  • relative androgen insensitivity in ARs with a larger number of CAG repeats
  • Because circulating testosterone is regulated via negative feedback through the hypothalamic-pituitary-gonadal axis, diminished androgen sensitivity at higher CAG repeat lengths may reduce feedback suppression of luteinizing hormone (LH). LH would then be maintained at higher levels, in turn promoting higher testosterone production
  • Testosterone up-regulates AVP expression in the amygdala
  • Oxytocin exerts an inhibitory influence on AVP expression in the central amygdala, and the synthesis of oxytocin is mediated by estrogen and estrogen receptors
  •  
    Study used saliva to measure Testosterone levels in men.  Testosterone levels were inversely associated with age, but positively associated with CAG repeat sequences in the AR.

    Topical hormones best evaluated via saliva and/or blood spot. Urine and particularly serum does not increase with dosing.  That does not mean the topical hormone therapy is ineffective, just that serum and urine are not optimal to follow topical therapy.  When looking at endogenous hormones without any therapies: serum, saliva, urine, and blood spot are equivalent.
