Periodic Limb Movements of Sleep measurementsconfirmedthat ULDNallowed equivalent control of limb movements at half the prior dose of D2/3 agonists. Although the naltrexone dosewas 0.15 ug, the effect was retained at 100 ug and 1 mg(Bear and Kessler, 2014a,2014b).Thus, naltrexone proved effective forRLS, putativelyby facilitating sensitization of D2/3 agonists.
The sources are patents. 2014a and 2014b.
It is interesting that the benefits were retained over a large dose range. Oddly, full doses (when combined with benzos) can help treat tardive dyskinesia. Thus, it seems plausible that the benefits for RLS are retained at even higher doses. I've not yet checked the sources to see if higher doses were tested. That is, doses over 1 mg. I doubt they were, because it would probably have been mentioned here.

the best known example of this type of research concerns the co-evolution of pastoralism and lactose tolerance [30]. In rough terms, the basic hypothesis—which is widely accepted and well confirmed—is that the adoption of dairying set up a modified niche in which the ability to digest lactose into adulthood was at an advantage.
Best known example of gene-culture coevolution - co-evolution of pastoralism and lactose intolerance - the adoption of dairying set up a modified niche - in which the ability to digest lactose into adulthood was an advantage. - ancestors who were lactose tolerant could take advantage of a new source of calories. - Hence it is the learned acquisition of dairying which explains the natural selection of genes favoring lactase persistence, - the continued production of the enzyme lactase beyond weaning - Dual inheritance theory (Gene-culture coevolution) typically uses this example to explain - Dairying is inherited via a cultural channel - lactase persistence is inherited via a genetic channel - Recent supporters of this also make recent claims that it is not possible to distinguish between - what is biological from what is cultural

Vulnerable users increasingly felt the effects of Karl Popper's Paradox of Tolerance, that if we include in a more tolerant discussion those who are less tolerant, they will prevent the discussion from being fully open. (Thus, in Popper's view, some level of "intolerance towards intolerance" must be exercised even by the tolerant.)

I found this paragraph in a New York Times article about Elon Musk’s attempts to buy Twitter striking: The plan jibes with Mr. Musk’s, Mr. Dorsey’s and Mr. Agrawal’s beliefs in unfettered free speech. Mr. Musk has criticized Twitter for moderating its platform too restrictively and has said more speech should be allowed. Mr. Dorsey, too, grappled with the decision to boot former President Donald J. Trump off the service last year, saying he did not “celebrate or feel pride” in the move. Mr. Agrawal has said that public conversation provides an inherent good for society. Their positions have increasingly become outliers in a global debate over free speech online, as more people have questioned whether too much free speech has enabled the spread of misinformation and divisive content. In other words, the culture has changed; the law persists, but it does not and, according to the New York Times, ought not apply to private companies.
Ben Thompson argues that it is precisely culture that has now changed, seemingly in favor of being less tolerant towards the expression of certain opinions.
-
Munroe, though, assumes the opposite: liberty, in this case the freedom of speech, is an artifact of law, only stretching as far as government action, and no further. Pat Kerr, who wrote a critique of this comic on Medium in 2016, argued that this was the exact wrong way to think about free speech: Coherent definitions of free speech are actually rather hard to come by, but I would personally suggest that it’s something along the lines of “the ability to voluntarily express (and receive) opinions without suffering excessive penalties for doing so”. This is a liberal principle of tolerance towards others. It’s not an absolute, it isn’t comprehensive, it isn’t rigorously defined, and it isn’t a law. What it is is a culture.
Ben Thompson by highlighting an argument made by Pat Kerr, that free speech (although lacking a widely accepted definition) is about the tolerance we show others in expressing their opinions, equates it to culture.

The idea that “we as therapists shouldn’t talk about right and wrong” has become the very different idea that there is no right and wrong in the first place.
James Mumford says that therapists took the idea that they shouldn't talk to patients about right and wrong (to help create a safe space) morphed into: there IS no right and wrong.
I would add that this seems to have bled over into society.

The kappa agonist spiradoline failed to produce cross-sensitization, but coadministration of spiradoline prevented morphine and buprenorphine from producing cross-sensitization. The ability of spiradoline to block cross-sensitization was itself blocked by the kappa antagonist nor-binaltorphimine.
This suggests to me that it is the opioid tolerance itself that determines cocaine sensitivity. To test this, I'd like to see a study that administers a KOR agonist after tolerance to opioids has been established, and see if this reverses cocaine sensitivity.

Repeated treatment with (-)U-50,488H (s.c. or i.c.v.) significantly enhanced antinociceptive effect of both mu-opioid receptor agonist (morphine) and delta-opioid receptor agonists
Just confirming what I believed to be the case. I couldn't remember whether I'd read results of this specific sort, so I figured I should look it up. Chronic KOR agonism appears to be an ideal opioid hack.

Firmina will be the longest cable in the world capable of running entirely from a single power source at one end of the cable if its other power source(s) become temporarily unavailable—a resilience boost at a time when reliable connectivity is more important than ever.
i was going to ask what good it is having a cable that has power, but not the data center behind it.
i guess the situation is that the fiber optic cable also has power cables running along it too, powering the repeaters, and it's the power cables that might break. in this case, having single ended power would be very useful.
i'm most curious to know how power is sent. is this 48V dc? higher? how much? kV?

In contrast to its acute administration, repeated salvinorin A administration did not modify dialysate DA levels. Similarly, neither basal extracellular DA levels nor DA uptake was altered. Unlike synthetic KOPr agonists, prior repeated administration of salvinorin A did not attenuate the locomotor activating effects of an acute cocaine (20 mg/kg, i.p.) challenge. However, cocaine-evoked DA overflow was enhanced.
Fascinating and useful stuff. This is close to what I was expecting. Though, I was expecting chronic exposure to upregulate dopamine beyond baseline. If I'm understanding this correctly, it was upregulated in the sense that it enhanced the dopaminergic effects of cocaine. I've not yet read the full study.

Systemic administration of ultra-low doses of naltrexone (16.7, 20.0, and 25.0 ng/kg) with morphine (1.0 mg/kg) extended the duration of the morphine-induced conditioned place preference.
This is important because it suggests mood-brightening. Contrast this with combining L-type calcium channel blockers with opioids, which appears to limit tolerance to opioid analgesia that does not correspond to mood brightening.

However, coadministration of nefiracetam (5 or 10 mg/kg, p.o.), enprofylline (30 mg/kg, p.o.) and rolipram (0.3 or 1 mg/kg, i.p.) with morphine during the pretreatment period, significantly reduced the withdrawal signs, moreover, the tolerance was significantly attenuated.
Looks promising. It's odd that theophylline had a lesser effect.

Conclusion: Our data suggest that the combination of VLF with morphine may be a relevant therapeutic implication to manage pain even when tolerance to morphine exists. Moreover, our data demonstrates the involvement of L-Arg/NO/cGMP pathway in the prevention of morphine tolerance and dependence by venlafaxine.
It's not clear if this has relevance to the subjective effects. I'm starting to think that I won't get an answer anytime soon.

Results: Tadalafil showed anti-nociceptive effect when given alone at different doses (p<0.05). However, tadalafil significantly decreased the analgesic effect of morphine (p<0.05). In addition, tadalafil significantly increased the tolerance to morphine (p<0.05). Conclusions: The phosphodiesterase type 5 inhibitor tadalafil have anti-nociceptive properties and it decreases analgesic effect of morphine, in addition improves tolerance development. These effects probably may occur via NO/cGMP pathway.
This is analgesia, so is not necessarily relevant for my purposes. Nonetheless, there implies some relevance of cGMP, but the direction isn't yet clear.

Repeated KOR agonist exposure, on the other hand, can result in opposing effects on the dopamine system [27], and desensitization of the KOR [28]

PAT is apparently an herbal medicine I should look into. They also imply that KOR agonists act as I expect they do, but I'll need to read the full study to be sure.
Edit: yup, it appears that chronic KOR agonism is probably a good idea.
from full text "Utility of KOR agonists is a promising pharmacological tool for attenuating morphine tolerance (Pan, 1998), however, it is difficult to find effective KOR agonists that are devoid of dysphoric and psychotomimetic adverse effects in humans"

The results also showed that diltiazem was able to selectively potentiate the analgesic effect of morphine but not of fentanyl (the reason was not known).
Fascinating. However, this provides no insight into the subjective effects. However, it does reduce my certainty that any given combination of drugs (sharing these mechanism) will work. There doesn't seem to be consistent results with these L-CCBs plus opioid studies.

These results suggest that the elevation of the cyclic AMP levels is involved in the development of morphine withdrawal syndrome and that blockade of the morphine-induced reduction of cyclic AMP levels by chronic rolipram inhibits the development of dependence and the behavioural and biochemical changes induced by naloxone. Furthermore, rolipram may be a useful drug for attenuating the development of morphine dependence.
Excellent. This implies that theobromine may help prevent opioid tolerance.

Big corporations have been doing this for a while.

The world is more beautiful the more you accept.”

Cessation of nitrous oxide resulted in characteristic convulsions similar to those seen in alcohol withdrawal in all mice.
This demonstrates that tolerance is possible. However, exposure in humans lasts only several minutes at a time. Let's assume 3 exposures per day lasting 10 minutes each (i.e. 30 minutes total). It would take 68 days to reach 34 hours of exposure. Alternatively, that's a ratio of 1 to 47 exposure to non-exposure. It's unclear whether that would be sufficient for tolerance.
In the 50% exposure group, convulsion score was effectively zero by hour 6 (from full text). This does not mean that withdrawal symptoms were gone. However, it does imply that recovery is rapid. It seems plausible that 20 hours between doses is sufficient to reach baseline, rendering tolerance in humans extremely unlikely. I will need to compare to alcohol withdrawal to confirm.
Edit: Alcohol withdrawal in mice can be induced with 72 hours of alcohol exposure. That implies it is similar to NO. In humans, "the shakes" appear to last 1 or two weeks. In mice, convulsions appear to be half gone in 25 hours, suggesting that they last a few days. Thus, it appears that NO withdrawal is possibly an order of magnitude shorter than alcohol withdrawal.
In conclusion, NO used in a normal fashion is unlikely to be harmful (except for risk of inducing B12 deficiency). Even if it is harmful, the short half life means that it will be apparent very quickly. I'm aware of several reports of B12 deficiency from NO abuse, but I haven't seen any reports of withdrawal symptoms.

While somewhat modest in size, the literature on chronic tolerance to nicotine in humans is reasonably consistent in showing clear evidence of tolerance to subjective mood effects but little or no tolerance to cardiovascular, performance or other nicotine effects
This is what I'd expect for tobacco, but it tells me little about nicotine. Most of the subjective effects are not from tobacco, so It's still plausible that nicotine does not develop tolerance. Indeed, the effects that don't go away are the effects expected from nicotine.

This book is not about religion, although I talk about religion. It's about religious tolerance and the fight for human rights; the first battlefront in public discourse about human rights.
Freedom of religion was the first base upon which other understandings of freedom have been built upon.
-
This is the story of 16th century Europe, and the political earthquake that was protestantism. The overarching historical narrative unfolds around the lives of fictional characters who might have lived in this historic period.
Follett's literary reenactment explores the intricacies of the Protestant Reformation through a cast of strategically diverse characters, whose stories span across multiple continents, nations, and cities. Each character is an important harbinger of larger historical trends. Within the masterfully established geo-political reality, each of their decisions serve to gradually reveal their distinct personalities and temperaments, belief systems and ideologies, and cultural identities.
-
The real enemies, then as now, are not the rival religions. The true battle pitches those who believe in tolerance and compromise against the tyrants who would impose their ideas on everyone else—no matter what the cost.
Reminiscent of our current geo-political climate. The extended cycles of history.

Most people reading this will already be fairly tolerant. But there is a step beyond thinking of yourself as x but tolerating y: not even to consider yourself an x. The more labels you have for yourself, the dumber they make you.
The only counter-argument that comes to mind for me didn't form itself until I had read this last paragraph a few times.
If your identity marker connotes tolerance then it hopefully has the opposite effect. Insofar as the experience of marginalization promotes empathy such identities might be good evidence for intelligence, and I do think individuals who feel oppressed or marginalized tend to empathize with others who suffer for different, marginalized identities.
These identities will only breed stupidity if the individual feels a competition for scarce resources that overwhelms their empathy, whence the perniciousness of the belief in zero sum attention economics as a greater threat to activism than inaction, ignorance, and exhaustion.
