The above findings suggested a potential functional role for P311 in renal fibrosis. To examine this hypothesis, we analyzed P311−/− mice and found that obstructed kidneys in both P311+/+ and P311−/− mice exhibited tubular dilation and atrophy, interstitial matrix deposition and inflammatory cell infiltration (Fig. 3A). These changes were more severe in P311+/+ mice. Quantitative analysis of Masson trichrome-positive areas revealed an approximately 1.43-fold increase in interstitial collagen deposition in P311+/+ mice compared to P311−/− mice after UUO (Fig. 3B,C, P = 0.005). Real-time PCR showed that collagen I mRNA levels were very low in the P311+/+ and P311−/− Sham groups, but were significantly increased in the UUO groups. However, collagen I mRNA expression increased more in P311+/+ mice than in P311−/− mice after UUO (Fig. 3D, 1.69-fold difference, P = 0.010). Vimentin expression was significantly higher in obstructed kidneys from P311+/+ mice compared to P311−/− mice, as determined by western blot (Fig. 3E,F, 1.52-fold difference, P = 0.024). Therefore, these results suggested that P311 promotes renal fibrogenesis in a mouse model of UUO.

(A) Representative HCN4 current traces from cells that underwent cholesterol depletion by MβCD (red) or enrichment by MβCD/cholesterol (blue) were compared to control (black). (B) Current densities of HCN4 are reduced upon cholesterol depletion and unchanged with enrichment. (C) Steady-state activation was not affected by modification of membrane cholesterol content. (D,E) HCN4 channel activation can be fit by a dual-exponential function whose 2 components were unchanged compared to control. (F) The kinetics of HCN4 deactivation can be described by mono-exponential functions which were slowed with cholesterol depletion and enrichment. (n > 8; P < 0.05).

Addex Therapeutics (SIXSwiss:ADXN.SW ; OTC:ADDXF ; Berlin:APE.BE ) is a development stage company focused on advancing innovative oral small molecules against rare diseases utilizing its pioneering allosteric modulation-based drug discovery platform. The Company’s two lead products are being investigated in Phase 2 clinical testing: dipraglurant (ADX48621, an mGlu5 negative allosteric modulator or NAM) is being developed by Addex to treat Parkinson’s disease levodopa-induced dyskinesia (PD-LID) and rare forms of dystonia; and ADX71149 (mGlu2 positive allosteric modulator or PAM) is being developed in collaboration with Janssen Pharmaceuticals, Inc. to treat both schizophrenia and anxiety as seen in patients suffering from major depressive disorder. Addex is also advancing several preclinical programs including: GABA-BR positive allosteric modulator (PAM) for Charcot-Marie-Tooth (type 1a) disease, spasticity in patients with multiple sclerosis (MS), pain, overactive bladder and other disorders; and mGlu4 PAM for MS, Parkinson’s disease, anxiety and other diseases. Allosteric modulators are an emerging class of small molecule drugs which have the potential to be more specific and confer significant therapeutic advantages over conventional ‘orthosteric’ small molecule or biological drugs. The Company uses its proprietary discovery platform to target receptors and other proteins that are recognized as essential for the therapeutic modulation of important diseases with unmet medical needs.

        The total intrinsic values of options exercised totaled $0.9 million and $1.4 million for the years ended December 31, 2018 and 2017, respectively. The intrinsic value was calculated as the difference between the fair value of the Company’s common stock and the exercise price of the option. The weighted-average grant date fair value of stock options granted was $6.63 and $11.57 for years ending December 31, 2018 and 2017, respectively.

I’ve often thought that one of the brain’s greatest abilities is the ability to forget. Hence I would be quite surprised a rejuvenated brain would have any difficulty adapting to existing in a rejuvenated body.

The Pharma Services business of Thermo Fisher Scientific will invest $150 Million at three facilities.

“So we arrive at the million-dollar question: Are regulatory agencies and pharmacopeias doing a good enough job, if a sponsor can comply with [most] regulations and yet send a product on the market which contains carcinogens,” asks Anders Fuglsang, founder of Fuglsang Pharma. “We can’t test for everything, but I’m not entirely happy with that statement as a patient or consumer,” he says. Fuglsang hopes that there will be an independent analysis of the root cause of the nitrosamine contamination, performed by independent experts outside of regulatory agencies or pharmacopeias. In the end, he says, “we can only find what we are looking for.” But the sartan API contamination case suggests a need to focus more closely on assessing potential risks during process synthesis review.

My thoughts on excessive high intensive exercise is that it may be the depletion of essential minerals (such as magnesium), may lead to worse health outcomes. This may be because it would then lead to poor blood sugar control. I say this because as a heavy gym user (combined with excessive alcohol use), I suffered muscle twitching and some high blood sugar episodes (resolved by giving up alcohol for a week and going low carb).
