An evergreen note on reading restricted paper:
First stop for seeing if there’s a free version of a paper, use the Google Scholar Chrome extension (Mac version), Google Scholar itself or try ResearchGate.
3 other helpful browser extensions are: Unpaywall, Open Access Button & PaperPanda
For the infamous backdoor, use Sci-Hub – the pirated papers repository (Chrome extension here). This works better for older paper than the stuff that just came out.
For Twitter users, send a Tweet of the paper’s title with the hashtag #icanhazpdf. It works because people are beautiful(ish).
Finally, email the author. They’re almost always happy to oblige because, thanks to the predatory academic publishing system, they don’t make a dollar off of their papers.

Endocannabinoids, anandamide and 2-AG, regulate mechanosensitivity of mucosal afferents in the Guinea pig bladder

As often happens, anandamide & 2-AG were the yin & the yang. “Our data indicated that anandamide and 2-AG have opposite effects on mechanosensitivity of mucosal capsaicin-sensitive afferents in the guinea pig bladder; mAEA potentiated while 2-AG inhibited responses of mucosal afferents to mechanical stimulation.”

PS: For this week’s single-note picking blues album, Scrapper Blackwell’s ‘Mr. Scrapper's Blues’. Part Cherokee & one of 16 children born in upstate New York, Scrapper got his nickname from his grandmother for his fiery nature. He built his first guitar out of a cigar box & taught himself to play. He was a working musician by his teens & by the mid-1920s, he became famous for his musical collaboration with the pianist Leroy Carr. By 1935, together they recorded over 100 songs before the war years cut down the music industry. He experienced a revival in the ‘50s with the beginning of the folk music revolution, but sadly, he was killed by a mugger in an Indianapolis alleyway. Now he’s known as one of the most important guitarists of the ‘20s & ‘30s.
