  • The outbreak of the war changed Emerson, who had disdained political parties, mistrusted philanthropic efforts, and once called himself "a seeing eye, not a helping hand." He labeled the war "a new glass to see all our old things through." It was "instructor," "searcher" "magnetizer" and "reconciler." Emerson the individualist and idealist may have bristled at the churning power of the machinery of war, but Emerson the patriot and realist welcomed the struggle for the birth of a new social order. "The War," Emerson realized, "is serving many good purposes .... War shatters everything flimsy and shifty, sets aside all false issues, and breaks through all that is not real as itself."

  • The biosinthetic path that allow Psilocybin to be produced by mushrooms is as follow:
  • The several analogyes with triptophan aminoacid, with whom psilocybin has common origines are probably at the base of psilocybin ability to induced psychedelich alteration on humans.
  • Amino acids, including tryptophan, act as building blocks in protein biosynthesis. In addition, tryptophan functions as a biochemical precursor for many compounds like serotonin Serotonin (a neurotransmitter), synthesized via tryptophan hydroxylase. Serotonin, in turn, can be converted to melatonin (a neurohormone), via N-acetyltransferase and 5-hydroxyindole-O-methyltransferase activities

  • it's been noticed that psilocyn can indirectly raise dopamine concentration withing the basal ganglia.
  • Almost 50% of oral psilocybin is absorbed by stomach and gut; from here is lead to liver, where it's converted in psilocin, pharmacologically active form, that can furtherly be glucoronated and escreted with urine or converted in other psilocinics metabolites.
  • In rats, the median lethal dose (LD50) when administered orally is 280 milligrams per kilogram (mg/kg), approximately one and a half times that of caffeine. When administered intravenously in rabbits, psilocybin's LD50 is approximately 12.5 mg/kg
  • traces of the compund can be detected in unine even after 7 days.
  • Clinical studies show that psilocin concentrations in the plasma of adults average about 8 µg/liter within 2 hours after ingestion of a single 15 mg oral psilocybin dose; psychological effects occur with a blood plasma concentration of 4–6 µg/liter. Psilocybin is about 100 times less potent than LSD on a weight per weight basis, and the physiological effects last about half as long.
  • Within 24 hours from administration 65% of the alucinogen is escreted by urine, while another 15-20% is excreted by bile and feces.
  • Monoamine oxidase inhibitors (MAOI) have been known to prolong and enhance the effects of psilocybin. Alcohol consumption may enhance the effects of psilocybin, because acetaldehyde, one of the primary breakdown metabolites of consumed alcohol, reacts with biogenic amines present in the body to produce MAOIs related to tetrahydroisoquinoline and β-carboline. Tobacco smokers can also experience more powerful effects with psilocybin, because tobacco smoke exposure decreases levels of MAO in the brain and peripheral organs.
  • This could lead to a lower usage o f glucose, but the same study admitted an increase glucose usage by the whole brain cell, meaning a differente use of this sugar while the drug is having effects.
  • use of MRI (functional magnetic resounance) showed that the decresed blood flow associate with decreasing in neural activity. A simple explanation for this unexpected situation could be the serotoning agonist action of psilocybin, action that seems to be focused more on 5-HT receptors than on 5-HT2A.
  • psilocibyn is able to act as a 5-HT agonist binding directly its receptors.
  • augmented glucose consumption in several brain regions; this lead to the conclusion that psilocybin is some way able to modify the physiological glucosal metabolic rate of our body
  • The strong inibition of the PCC is now thought to be most significant action of psilocybin on neural disaccoppiation

      Lower brain glucose metabolism is linked with increased capacity for working memory.
  • Psilocybin comprises approximately 1% of the weight of Psilocybe cubensis mushrooms, and so nearly 1.7 kilograms (3.7 lb) of dried mushrooms, or 17 kilograms (37 lb) of fresh mushrooms, would be required for a 60-kilogram (130 lb) person to reach the 280 mg/kg LD50 value.
  • psilocybin can cause anxiety and increased heart rate and BP which is very counter- productive for someone on metoprolol and micardis.
  • propose the possibility to use psilocybin as a palliative therapy for terminal illness like cancer but also as a real antidepressive active principle available for the family of the patient. The rational is foundable in the fact that we usually administer SSRI as antidepressive agents, so psilocibyn sholud be useful in this purpose for its selective agonist action on 5-HT2A receptors

  • was also concerned about her students’ lack of engagement — so few were completing the assignments she emailed to parents
  • Playing with her family’s laundry marked the first time Maliah seemed happy — actually happy — since the start of the pandemic.

      NOTE - happy - happy is good. Happy kids want to learn or are more likely to learn.
  • Nobody should ever be penalized or put at a disadvantage for the supplies they don’t have,” Dillingham thought to herself. “But everyone’s got laundry!”

  • Clark started an online fundraiser to pay for bikes. He raised more than $10,000, and neighbors donated dozens of bikes and helmets for the rides.

  • She couldn’t be sure whether her kids were uninterested or whether they lacked the necessary pens, paper and crayons at home.
  • He decided he would take his students on socially distanced bike rides across the city. “It was a leap of faith. I got extremely nervous. I was trying to find a way to connect with kids,” Clark said.
  • her young students are musical detectives, in search of learning. She teaches most grade levels and the school chorus.

  • t he’s found other ways to keep his students engaged and cycling the city. He invited students to a weekly entrepreneurship class for which they rode their bikes uptown from Dunbar to the gym where Clark works, Sweat DC. The students met with the owner of the gym and the owners of a nearby bar, Hook Hall, and the bagel shop Call Your Mother Deli to learn what it takes to run a business.
  • She wanted them to create their own composition, their own snowy-day song.

  • When Clark wanted to teach them about resilience, he took them through the hilly streets of Georgetown.
  • In lessons for older students, some days there were makeshift drums involved or recorders that students had taken home.
  • she was able to use the treehouse as a key part of her lessons.
  • She lugged a bookshelf, desk and heater into the 5-by-7-foot space, and ran an Ethernet cable from the house so she’d have Internet.

  • Kids need connection, he said. “I think they’re starving for conversation,” including with adults.
  • In fifth grade, students are expected to learn how to add, subtract, multiply and divide with whole numbers, decimals and fractions. Through a computer application the students have, they can program the robot to move a certain distance, stop, maybe even turn.

  • With learning all-virtual, he packs a big Ziploc bag — for each student, each quarter — with things like fishing line, foam board, pipecleaners, magnets, Popsicle sticks and rubber bands. Whatever they will need for their projects.
  • And a lot of the math is a little sneaky. They think they are trying to get the robot to move, when they are actually measuring the angles to get it to move.”  
  • Others complete their math problems directly on the computer, which can lead to some troubles as they try to show their work.
