Some General Resources:

Antimicrobial Agents  - Cell wall inhibitors

Based on mode of action • divided into families based on chemical structure

 Modes of action Interference with: 

cell wall synthesis 

protein synthesis 

nucleic acid synthesis 

plasma membrane integrity 

metabolic pathway 

Inhibitors of Bacterial Cell Wall (peptidoglycan) Synthesis 

The Beta-lactam Family 

The Glycopeptides 

Peptidoglycan is composed of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) repeat units, and amino acids.  Each NAM is linked to peptide chain and the peptide chains are cross-linked.

β-lactams 

Includes penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems.

class of broad-spectrum antibiotics containing a β-lactam ring

Bacterial transpeptidase enzymes are responsible for catalysing cross-linking of the peptide chains

β-lactam ring bind to these transpeptidases – this inhibits cross-linking between peptide chains and prevents synthesis of stable PG

Cell wall synthesis ceases and the bacterial cells eventually die due to osmotic instability or autolysis. 

Glycopeptides 

Polypeptide agents - basic structural elements amino acids 

Vancomycin: 

complexes with peptide portion of peptidoglycan’s precursor units 

vancomycin is a large hydrophilic molecule able to form hydrogen bonds with the terminal D-alanyl-D-alanine moieties of the NAM/NAG-peptides

preventing PG transglycosylation reaction – PG precursor subunits (NAG-NAM+peptide) cannot be inserted into peptidoglycan matrix;

Vancomycin also alters bacterial-cell-membrane permeability and RNA synthesis

Uses:  serious Gram positive infections e.g. MRSA wound infection

Adverse effects:

damage to auditory nerve 

hearing loss (ototoxicity) 

“Red man/neck” syndrome - rash on face, neck, upper torso 

I need tips on taking textbook notes please! I always get bored reading and then I end up just writing down bolded words with no context (which is really bad I know) any tips to help take more efficient textbook notes without having to spend hours (because I have 3 content heavy classes that I need to take notes for)

Hi there! I know this post may feel basic, but I feel like you’re struggling with basic skills like summarising a topic and writing things in your own words, so I tried my best to explain things in a step-by-step action-oriented list so that you can stand on your own ‘feet’ when you’re studying :)

The Basics of Studying From a Textbook

1. The textbook may be boring, but you’ve still got to read it. 

Unfortunately, high school and university isn’t a walk in the park :( I know, some days it’s hard, but you’ve still got to put in at least a modicum of hard work if you want to do well. 

Sometimes, the studyblr community perpetuates the idea that there’s some sort of “secret” to being a straight-As, 4.0GPA, HD WAM student, but there’s only studying techniques to make things easier. You’re still going to need a basic level of motivation, discipline, time management, organisation and study in order to do well. 

So even though the textbook is boring, you’re either going to have to convince yourself that the topic is interesting, or pull up your socks, buckle down, and actually read it. 

2. Reading speed is a limiting factor on how fast you can take notes. 

Try reading the textbook without taking any notes and time how long it takes you. That’s going to be the minimum time it takes, so if doing all the reading for 3 content heavy courses takes at least an hour or two, then reading and taking notes is going to be much more than that (roughly more than double the time), so you can’t speed it up any faster than your base reading speed. 

I recommend trying speed reading techniques, but that would take a whole separate post, so I won’t go into that here. 

3. Learn how to summarise a topic. 

At the moment it seems like you’re struggling and not really understanding how to summarise topics, and just relying on the textbook to tell you what’s important. 

To summarise something, you’ll need to write down the key points (the most important information) from something that you read in the fewest number of words reasonable. I’m sure you already knew that, but you must not be putting it into practice because of what you’re telling me in your ask. 

4. Write things in your own words. 

Again, once you learn how to summarise, writing it in your own words will solidify that information in your brain. Explain the topic in layman’s terms to a family member, which forces you to use your own words. If you live alone, try a stuffed toy or rubber duck. 

5. Start off by annotating your class notes. 

I think initially you should start off with annotating just until you learn what information is important and what’s not. Class notes usually have 80% of the important information in brief points, and the textbook colours in the rest. 

6. Use the “gummy bears” method. 

I know it’s elementary, but you seemed to be having trouble with discipline and boredom, so place gummy bears on every paragraph as a crutch to get yourself to finish reading everything. Once you train yourself to do things that you don’t want to do, then you won’t have to use any cheap tricks, as you’ll be disciplined enough to read pages and pages without needing constant “carrot on a stick” rewards. 

Once you’ve done those, here are my masterposts for content heavy courses:

desmosome a circular, dense body that forms the site of attachment between certain epithelial cells, especially those of stratified epithelium of the epidermis, which consist of local differentiations of the apposing cell membranes.

-Exfoliatin

A staphylococcus toxin - Cleaves the desmosomes in the stratum granulosum - Separates layers of skin. - Example: Scalded skin syndrome (occurs more often in infants)

Ketone bodies are produced in the liver and can be used as an energy source in the mitochondrial of peripheral tissues. Important fact: RBCs can not use ketones because they lack mitochondria.

The liver is unable to peform Ketolysis because it lacks Thiophorase (Succinyl-CoA Acetoacetate Transferase), and is hence unable to activate its own ketones.

Hey, I’m back with another masterpost. I decided to include some of my tips.

Use the forest app to keep you off your phone, your phone is a distractions you face when studying

Try making a to-do list to plan out how much time you take to do each task so you keep track of time

Set rewards i.e. if I finish this task at 9am instead of 9.30am, I’ll watch my favourite tv show for 1 hour instead of 30mins.

How to be disciplined

I guess this is pretty much like a habit. So try to maybe start small, i.e. study 10 mins each day and gradually increase the time limit if you feel comfortable doing so. The reason I chose 10 mins is because it seems like a very short period of time so it’s easier for you to get to work.

How to manage studies with social media

Always set a time period for your school work. For example, after 30 minutes of browsing through your social media, force yourself to do a piece of school work. That way, you will still get work done instead of browsing through your social media all day long.

If you realise on tumblr, I don’t come up with an original post every day and I tend to reblog my old post or queue others posts so don’t stress too much on coming up with a post. For instagram, you could try to take pictures all during the weekend, so you don’t have to stress taking them after school, etc.  But it is important to always put studies first before your social media.

Consider switching off your phone or even deleting your social media apps or deactivating them during exams period if they are really getting in the way of your studies.
