Oh, the overwhelming, never-ending, reckless love of God. Oh, it chases me down, fights ‘til I’m found, leaves the ninety-nine. I couldn’t earn it, and I don’t deserve it, still, You give Yourself away.

People move to new cities for people and with people who they might not be talking to in two years. People combine their life savings and have children with people who they no longer can be in the same room as. Because nothing is certain and no love is guaranteed and life is unpredictable and things change. That’s why the only personality you absolutely HAVE to love is your own, the only one whose happiness is always going to affect you and be controlled by you is your own, and the most important life that you need to go out of your way to improve is your own.

“Your ambition should be to get as much life out of living as you possibly can – as much enjoyment, as much interest, as much experience, as much understanding. And not to simply be what is generally called a “success”.”

“Never speak of marriage as an achievement. Find ways to make clear to her that marriage is not an achievement, nor is it what she should aspire to. A marriage can be happy or unhappy, but it is not an achievement. We condition girls to aspire to marriage and we do not condition boys to aspire to marriage, and so there is already a terrible imbalance at the start. The girls will grow up to be women preoccupied with marriage. The boys will grow up to be men who are not preoccupied with marriage. The women marry those men. The relationship is automatically uneven because the institution matters more to one than the other.”

“Educate yourself. When a question about a certain topic pops up, google it. Watch movies and documentaries. When something sparks your interest, read about it. Read read read. Study, learn, stimulate your brain. Don’t just rely on the school system, educate that beautiful mind of yours.”

“Learn to type. Learn to drive. Have fun. Write postcards. (Letters take too long and you won’t do it, a postcard takes two minutes.) Be punctual. Don’t worry about what other people are thinking. They are not thinking about you. Write quickly. (Taking longer doesn’t usually make it better.) Get up early. See the world. Call everybody by their first name, from doctors to presidents. Have parties. Don’t agonise. Don’t regret. Don’t fuss. Never brood. Move on. Don’t wait for permission to be happy. Don’t wait for permission to do anything. Make your own life …

Don’t live for the weekends. Don’t write off things you’re unsure of. Don’t mistake comfort for love. Don’t mistake attention for love. And most importantly, don’t believe anyone who says they don’t have time to see you, because there’s no such thing as being too busy for something you care about.

Don’t you think it’s crazy how one decision can determine the course of your life. If I went to the dining hall a half hour later on the day I met my first boyfriend, my life could have been completely different. I could have eventually met him somewhere else and still fallen in love with him, but I also could not have. I could’ve dated someone completely different who I might be engaged to right now. Or I could not have.
The classes you choose, the seats you choose in those classes, the way you choose to walk home on a particular night. They can all cause or prevent a major event in your life. It’s crazy because they’re decisions we consciously make, but we’re not actually choosing the outcome. And when it works out in our favor, it’s “fate” but when it doesn’t, we’re “unlucky.”

Penicillin

Penicillin is a widely used antibiotic prescribed to treat staphylococci and streptococci bacterial infections. 

  • beta-lactam family 
  • Gram-positive bacteria = thick cell walls containing high levels of peptidoglycan
  • gram-negative bacteria = thinner cell walls with low levels of peptidoglycan and surrounded by a lipopolysaccharide (LPS) layer that prevents antibiotic entry 
  • penicillin is most effective against gram-positive bacteria where DD-transpeptidase activity is highest.

Examples of penicillins include:

  • amoxicillin
  • ampicillin
  • bacampicillin
  • oxacillin
  • penicillin

Mechanism(s)

  • Penicillin inhibits the bacterial enzyme transpeptidase, responsible for catalysing the final peptidoglycan crosslinking stage of bacterial cell wall synthesis.
  • Cells wall is weakened and cells swell as water enters and then burst (lysis)
  • Becomes permanently covalently bonded to the enzymes’s active site (irreversible)

Alternative theory: penicillin mimics D-Ala D-Ala

Or may act as an umbrella inhibitor

Resistance

  • production of beta-lactamase - destroys the beta-lactam ring of penicillin and makes it ineffective (eg Staphylococcus aureus - most are now resistant)
  • In response, synthetic penicillin that is resistant to beta-lactamase is in use including egdicloxacillin, oxacillin, nafcillin, and methicillin. 
  • Some is resistant to methicillin - methicillin-resistant Staphylococcus aureus (MRSA).  
  • Demonstrating blanket resistance to all beta-lactam antibiotics -extremely serious health risk.
