  • 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

blogging education professionaldevelopment

  • What makes professional development even more frustrating to practitioners is that most of the programs we are exposed to are drawn directly from the latest craze sweeping the business world. In the past 10 years, countless schools have read Who Moved My Cheese?, studied The Seven Habits of Highly Effective People, learned to have "Crucial Conversations," and tried to move "from Good to Great."
  • With the investment of a bit of time and effort, I've found a group of writers to follow who expose me to more interesting ideas in one day than I've been exposed to in the past 10 years of costly professional development. Professional growth for me starts with 20 minutes of blog browsing each morning, sifting through the thoughts of practitioners whom I might never have been able to learn from otherwise and considering how their work translates into what I do with students.
  • This learning has been uniquely authentic, driven by personal interests and connected to classroom realities. Blogs have introduced a measure of differentiation and challenge to my professional learning plan that had long been missing. I wrestle over the characteristics of effective professional development with Patrick Higgins (http://chalkdust101.wordpress.com) and the elements of high-quality instruction for middle grades students with Dina Strasser (http://theline.edublogs.org). Scott McLeod (www.dangerouslyirrelevant.org) forces me to think about driving school change from the system level; and Nancy Flanagan (http://teacherleaders.typepad.com/teacher_in_a_strange_land) helps me understand the connections between education policy and classroom practice. John Holland (http://circle-time.blogspot.com) and Larry Ferlazzo, Brian Crosby, and Alice Mercer (http://inpractice.edublogs.org) open my eyes to the challenges of working in high-needs communities.

EdPsych teacher-education assessment value-added ROI

  • hey avidly recruited students and their families into the process; they maintained focus, ensuring that everything they did contributed to student learning; they planned exhaustively and purposefully—for the next day or the year ahead—by working backward from the desired outcome; and they worked relentlessly, refusing to surrender to the combined menaces of poverty, bureaucracy, and budgetary shortfalls.
  • one way that great teachers ensure that kids are learning is to frequently check for understanding: Are the kids—all of the kids—following what you are saying? Asking “Does anyone have any questions?” does not work,
  • Students are not always the best judges of their own learning.
  • Chris Sloan on 15 Jan 10
     
    "For years, the secrets to great teaching have seemed more like alchemy than science, a mix of motivational mumbo jumbo and misty-eyed tales of inspiration and dedication. But for more than a decade, one organization has been tracking hundreds of thousands of kids, and looking at why some teachers can move them three grade levels ahead in a year and others can't. Now, as the Obama administration offers states more than $4 billion to identify and cultivate effective teachers, Teach for America is ready to release its data."

    Article on teacher effectiveness as studied through Teach for American data. Thrilling and scary in implication all at the same time.

shared by Javier E on 31 Dec 10 - No Cached
  • life isn't as simple as it once appeared. Career and Marriage are transformed from abstract hopes into concrete decisions. Every one that is made closes off other possibilities. And every so often, we take stock of life, pondering its purpose, what it is that makes us happy, our responsibilities to others, whether meaning can be found in our work, etc.
  • prep schools and top tier colleges traffic in a perverse illusion: that building a perfect resume is the same thing as building a perfect life
  • since every subculture has its pathologies, you're probably not doing things right unless the other people in your world are at least slightly uncomfortable with some way in which you're challenging its assumptions.

Mary Higgins liked it
  • Your introduction is an important road map for the rest of your paper.
  • your introduction should contain a thesis that will assert your main argument. It should also, ideally, give the reader a sense of the kinds of information you will use to make that argument and the general organization of the paragraphs and pages that will follow. After reading your introduction, your readers should not have any major surprises in store when they read the main body of your paper.
  • Start by thinking about the question (or questions) you are trying to answer
  • ...10 more annotations...
  • our direct answer to the assigned question will be your thesis, and your thesis will be included in your introduction, so it is a good idea to use the question as a jumping off point.
  • Open with an attention grabber.
  • an intriguing example
  • Avoid statements like “In this paper, I will argue that Frederick Douglass valued education.”
  • a puzzling scenario
  • a vivid and perhaps unexpected anecdote
  • a thought-provoking question
  • a provocative quotation
  • less effective

Why Is Innovation So Hard? - 47 views

innovation

shared by Matt Renwick on 09 Aug 14 - No Cached
  • How does innovation occur?  Through an inefficient process of ideation, exploration, and experimentation.
  • we create new value by combining seemingly unrelated things or ideas in new ways, transferring something from one environment to another, or finding new insights in patterns or aberrations. Innovative ideas rarely emerge from an “aha!” moment. Instead, they usually arise from thinking differently than we normally think and from learning.
  • we are highly efficient, fast, reflexive thinkers who seek to confirm what we already know.
  • ...6 more annotations...
  • we are cognitively blind to disconfirming data and challenging ideas.
  • To innovate, people have to take their normal thinking to a much higher level. Most of us have to be taught how to do that.
  • Fear of failure, fear of looking bad, and fear of losing our job if we make mistakes all can lead to what Chris Argyris called “defensive reasoning”: the tendency to defend what we believe. This makes it hard to get outside of ourselves in order to “think out of the box.”
  • most organizations exist to produce predictable, reliable, standardized results. In those environments, mistakes and failures are bad.
  • To innovate, you must simultaneously tolerate mistakes and insist on operational excellence.
  • Humility, empathy, and the devaluation of hierarchical rank were critical to making this new culture work.
