Psilocybin (magic mushrooms) - 0 views

  • 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
    • Kenuvis Romero
       
      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

More Remote Learners in Your Future | From the Bell Tower - 7/16/2009 - Library Journal - 0 views

  •  
    What does this have to do with higher education? High gas prices got adult learners questioning the value of driving an hour each way to a college campus. Suddenly, online learning became vastly more attractive to a whole segment of higher education's market. Articles about fuel prices driving students to online courses became as prevalent as those about the impact of the recession on higher education are right now. While the price of fuel has retreated to a more manageable range, the number of Americans flocking to online higher education has shown no such decline.

A report says universities' use of virtual technologies is 'patchy' | Education | The G... - 1 views

  •  
    The "Google generation" of today's students has grown up in a digital world. Most are completely au fait with the microblogging site Twitter; they organise their social lives through Facebook and MySpace; 75% of students have a profile on at least one social networking site. And they spend up to four hours a day online. Modern students are happy to share and participate but are prone to impatience - being used to quick answers - and are casual about evaluating information and attributing it, and also about legal and copyright issues. With almost weekly developments in technology and research added to increasingly web-savvy students' expectations, how are British universities keeping up? Pretty well, according to Sir David Melville, chair of Lifelong Learning UK and author of a new report into how students' use of new technologies will affect higher education.

    Corrupted-Files.com offers a service -- recently noted by several academic bloggers who have expressed concern -- that sells students (for only $3.95, soon to go up to $5.95) intentionally corrupted files. Why buy a corrupted file? Here's what the site says: "Step 1: After purchasing a file, rename the file e.g. Mike_Final-Paper. Step 2: E-mail the file to your professor along with your 'here's my assignment' e-mail. Step 3: It will take your professor several hours if not days to notice your file is 'unfortunately' corrupted. Use the time this website just bought you wisely and finish that paper!!!"

Seth's Blog: Learning from the MBA program - 0 views

  • I taught for five to twenty hours a week, and very little of it was about the books. So, if concepts from books are easy, what’s hard?Doing it.Picking up the phone, making the plan, signing the deal. Pushing ‘publish.’ Announcing. Shipping.We spent a lot of time on this area. Every morning, each person came in prepared to push someone in the group to overcome the next hurdle. This is what growth looks like, and it was energizing to be part of.We didn’t do this at all at when I was at Stanford. We spent a lot of time reading irrelevant case studies and even more time building complex financial models. The thing is, you can now hire someone to build a complex financial model for you for $60 an hour. And a week’s worth of that is just about all the typical entrepreneur is going to need. The rest of the time, it’s about shipping, motivating, leading, connecting, envisioning and engaging. So that’s what we worked on.It amazes me that MBA students around the world aren’t up in arms. How can schools justify taking $100,000 in cash and teaching exactly the wrong stuff?

The National Networker (TNNW) Blog: BEYOND THE CUBICLE - CORPORATE CULTURE: T... - 9 views

  • The culture appears to be grounded in not only a need to share, but also a desire to be recognized. Retweets – when someone sends your tweet (message) out to their followers (a term supporting the need for recognition) somehow elevates your status within this community.
  • Social Media as a dominant force for communicating has penetrated every element of society. Can a virtual community possess a culture? Every company and organization possesses a definable culture. Behaviors, decision-making models, intrinsic and extrinsic actions and how people are treated may all play a part in defining it. These elements of culture are measureable and easy to define within a controlled entity. Social media lives and breathes in a virtual reality. It permeates all corners of the world, allows people to communicate across all traditional boundaries and thrives 24 hours/day. So…does it have a definable culture? If you have spent any time on Twitter, you quickly realize thousands of people have a need to respond to the question, “What’s happening?” Twitter has developed it’s own language with tweets, retweets, tweeple, twitpics, twibes, etc. You can follow topics with a hashtag and people with lists. What is most apparent is the need people have to share. The culture appears to be grounded in not only a need to share, but also a desire to be recognized. Retweets – when someone sends your tweet (message) out to their followers (a term supporting the need for recognition) somehow elevates your status within this community. There are etiquette protocols as many people publicly thank you for following them and for retweeting. Retweeting becomes a type
  • As you get deeper into the structure of Twitter, you can join a twibe or tweeple group, which provides inclusion – another indication that the need for recognition is systemic.

UCSD: Global Information Industry Center - 13 views

  • In 2008, Americans consumed information for about 1.3 trillion hours, an average of almost 12 hours per day. Consumption totaled 3.6 zettabytes and 10,845 trillion words, corresponding to 100,500 words and 34 gigabytes for an average person on an average day. A zettabyte is 10 to the 21st power bytes, a million million gigabytes. These estimates are from an analysis of more than 20 different sources of information, from very old (newspapers and books) to very new (portable computer games, satellite radio, and Internet video). Information at work is not included.

U.S. Urged to Raise Teachers' Status - NYTimes.com - 77 views

    • Steve Ransom
       
      Was it ever?
  • “Despite the characterization of some that teaching is an easy job, with short hours and summers off, the fact is that successful, dedicated teachers in the U.S. work long hours for little pay and, in many cases, insufficient support from their leadership.”
  • In South Korea, teachers are known as ‘nation builders,’ and I think it’s time we treated our teachers with the same level of respect,” Mr. Obama said in a speech on education on Monday.

  • “Make a concerted effort to raise the status of the teaching profession”
  • University teaching programs in the high-scoring countries admit only the best students, and “teaching education programs in the U.S. must become more selective and more rigorous,”
  •  
    ROK banned "beating" in schools about a month ago. So things are indeed different. We can compare pedagogy, but can we compare culture and outcomes that are embedded in culture? When children leave the classroom to take the TIMMS or PISA test, the rest of the class stands to applaud. When I explained this to my students, they were dumbfounded that Korean kids did anything that wasn't directly connected to personal advantage.
