"The Acute Satellite Cell Response and Skeletal Muscle Hypertrophy following Resistance Training"

http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0109739

Simply awesome. Been looking for a study like this for awhile.. demonstrating the actual importance in normal, resistance trained human subjects, of the satellite cell response for long-term hypertrophy.

Interestingly, looking at correlations toward chronic resistance training gains it's been found that:

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3933567/

There's no correlation between the level of activated/phosphorylated p70s6k (mTOR substrate, initiates ribosomal biogenesis) or for protein synthesis levels themselves acutely.
A correlation was found for 4E-BP1 though. It's also a substrate of mTOR, it's phosphorylation inhibits it and allows the translation initiation factor, eIF4, which allows protein synthesis itself to initiate/start.

I suspect perhaps there's other factors that allow proper biogenesis of ribosome complexes, making that distinct factor less important than the initiation of the translation itself.. though I'm not sure, perhaps someone else can shed light on other factors involved there specifically.

"Hypothalamic Programming of Systemic Aging Involving IKKβ/NF-κB and GnRH"

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3756938/pdf/nihms463346.pdf

Awesome paper. It sheds some light on something I was apparently overlooking: that is the influence of GnRH and thus various sex hormones on the aging process (ie low levels increase aging rate) and the apparent inherent activation of NFkB (increases pro-inflammatory cytokine levels) in aged animals.

I realize the deleterious influence of activation of microglia (essentially differentiated monocytes/macrophages that reside in the brain) and general inflammation in the brain, but I didn't realize a secondary influence of that on hormonal control @ the hypothalamus.

e: I'll also look into this a bit more, but my initial thoughts are, yet again, fasting could help increase longevity through mitigating NFkB activation. For instance, as fasting continues, there's a rise in norepi, which is immunosuppressive. It strongly impeded NFkB directly via several mechanisms including activation of HDAC4, CREB binding, stabilization of IkB, and activation of HPK1 to inhibit SLP-76 (luckily, I'm working on influence of norepi on T cell function so some of these pathways are becoming second nature lol)

"Discovery of a Class of Endogenous Mammalian Lipids with Anti-Diabetic and Anti-inflammatory Effects"

http://www56.z.i.p.p.y.s.h.a.re.com/v/46075542/file.html

Very interesting! Will have to thoroughly read this one through

Hopefully dl link doesn't error this time. It should be z.i.p.p.y.s.h.a.r.e (without .s)

I haven't quite finished this as it is over 400+ comments with MANY studies cited, however, I would strongly suggest HNF read it.

It is valuable information presented in an entertaining to read fashion.

However, Hahn has got to be one of the most irritating people...he argued like a child..

I'm not going to read the rest of it tonight, though I read a good chunk, and holy shit Hahn is a moron

"Regulation of skeletal muscle energy/nutrient-sensing pathways during metabolic adaptation to fasting in healthy humans"

http://ajpendo.physiology.org/content/early/2014/09/17/ajpendo.00215.2014

Waiting to get the full text..

However, assuming it holds up, I'm quite disappointed in no change in AMPK activity. That's one of the biggest factors I predicated much of a fasting stance around. I feel almost dishonest if this is completely true and even after 24hrs it doesn't really change activity.
Regardless, I'd still tout fasting as a great mediator of health & longevity via mitohormesis. Despite lack of AMPK signaling, FoxO, Sirt1 and I'm assuming factors such as NRF2 are still indeed increased, which does culminate in a hormetic response, thus still highly beneficial. I suppose fasting still has most of the beneficial effects I've touted on, it just doesn't have AS robust an effect in terms of inhibiting lipid & cholesterol synthesis, insulin-independent glucose uptake, etc.

"The Anabolic Androgenic Steroid Nandrolone Decanoate Disrupts Redox Homeostasis in Liver, Heart and Kidney of Male Wistar Rats"

http://www.plosone.org/article/infodoi10.1371journal.pone.0102699

- it increased NADPH oxidase levels & activity in the heart and liver
- it decreased catalase and superoxide dismutase in the liver
- it decreased catalase in the kidney
-  it reduced thiol residues

This essentially means that DECA administration increases oxidative damage via concomitant increase in production of the superoxide radical and a decrease in the activity of a couple of different endogenous antioxidants.

This study basically gives some mechanistic insight into exactly how AAS use can contribute to tissue damage that is sometimes seen

Maybe I'm wrong for even thinking like this, however, perhaps this implies that small doses.. such as slightly above normal levels (obviously normal levels imply, but maybe SLIGHT supraphysiological levels would be best), it would induce a mitohormetic response, augmented lifespan/longevity via these same outlined mechanisms. This study and a study cited in this paper note that the ROS prod is overproduced w/ respsect to the activity of the antioxidant systems.. however, smaller amounts of ROS signaling and general body stressors and can often induce mitohormesis, whereby your body becomes more robustly stress resistant by ramping up antioxidant defense capacities through a positive ROS signaling. This could also explain why men that go on TRT-esque doses most often become healthier.

My hypothesis may be supported by a few studies too:

"Testosterone increases renal anti-aging klotho gene expression via the androgen receptor-mediated pathway."
http://www.ncbi.nlm.nih.gov/pubmed/25163025

&

"The Neuroprotective Effect of Klotho is Mediated via Regulation of Members of the Redox System"
http://www.jbc.org/content/early/2014/07/18/jbc.M114.567321

Thus, testosterone - androgen receptor interaction signaling induces expression of the anti-aging gene/protein Klotho.. and Klotho is known to exert much of its protective and longevity benefitting effect through the redox system, the same one that is disrupted in the study from very high doses. Notwithstanding, perhaps the positive effects of AAS/testosterone are mediated most optimally, already, at the normal physiological level.


Looks like my surmise here may have even more evidence:

"Stanozolol treatment decreases the mitochondrial ROS generation and oxidative stress induced by acute exercise in rat skeletal muscle"

http://jap.physiology.org/content/110/3/661

I wonder if the very slight discrepancy in redox status is due to a dosage difference or simply difference between the anabolic agents? I don't suspect the latter as I have no reason to suspect that, but who knows.
