Hey everyone!
Let's revise the ovarian cycle today ^__^

Antibiotic sensitivity tests for gram positive cocci mnemonic

Hello there!
This is a short post on mnemonic for antibiotic sensitivity tests for gram positive cocci. 

Emoticon game on Microbiology: Part two

After an amazing feedback on the first game, we thought of making part two.

Mycobacterial biochemical reactions mnemonic

Hello!

We'll be learning about biochemical reactions for mycobacteria today.

Emoticon game on Microbiology

Hi everyone!

We will be doing something different and fun today ^___^
We are playing the emoticon game.. Difference is that it's on Microbiology!

Kinetics of drug elimination simplified

Hi everyone!
We will be covering kinetics of elimination today. =)
Let's get started!

Oxygen - hemoglobin dissociation curve mnemonic

Hi everyone!
What is oxygen - haemoglobin dissociation curve or oxygen binding curve?
The oxygen - haemoglobin dissociation curve plots the proportion of haemoglobin in its saturated form on the vertical axis (fractional saturation of hemoglobin) against the prevailing oxygen tension on the horizontal axis.

What does it tell?
It tells you the affinity of hemoglobin for oxygen.

How does it do that?
It's simple!
If the curve shifts towards the right, hemoglobin has decreased affinity for oxygen.
If the curve shifts towards the left, hemoglobin has increased affinity for oxygen.

How do I remember the shift in curves?
Remember: Left shifted curve doesn't want to leave oxygen.

Obstructive and restrictive lung diseases

Happy friday everyone!
We’ll learn about obstructive and restrictive lung diseases today.
This is just a short summary for a quick review :)


Obstructive lung diseases - Characterized by airway obstruction.
You have an obstruction in air flow resulting in air trapping in the lungs.
Increased compliance: Due to the loss of alveolar and elastic tissue.
You have a problem getting air out of your lungs.
Mnemonic: Obstructive Out

They breathe like “poof poooooof”
In and oooooout
They take infinity to get it all out =P
So, FEV1 / FVC is decreased.

TLC and RV increased - Flow volume loop shifts towards left.

Examples: Any pathology that decreases the ability to develop a positive intrapleural pressure.
(Airways close prematurely at high lung volumes!)
Chronic bronchitis
Asthma
Bronchiectasis
Emphysema
COPD

Restrictive lung diseases - Characterized by restriction of lung expansion.
You have a problem getting air into your lungs.
Reduced compliance: Lungs become fibrotic, lose their distensibility and become stiffer.
Mnemonic: Restrictive Reduced compliance

They breathe like “poof pof”
In and out
They get everything out in one second =P
So, FEV1 / FVC is increased.

TLC and RV decreased - Flow volume loop shifts towards the right.

Examples: Any pathology that decreases the ability to develop a negative intrapleural pressure.
Pulmonary fibrosis
Asbestosis
Sarcoidosis
Pneumoconioses
Kyphoscoliosis
ARDS
Polio
Obesity

That's all!

I know you must've found the "poof" sounds pretty weird because that isn't the way you breathe
But they are a funny and they help me remember so I put it up anyway ^___^"
Just like "lup dubb" are official sounds for heart beats.. Which sounds would you assign to inspiration and expiration?

What are the factors affecting diastolic blood pressure?

Hi everyone!

What is diastolic blood pressure?
It is the pressure that is exerted on the walls of the various arteries around the body in between heart beats when the heart is relaxed.
It is the minimum pressure in the entire cardiac cycle.
So it basically represents amount of blood in arterial system during diastole.

Lateral medullary syndrome and lateral pontine syndrome mnemonic

*Super super excited to share this mnemonic with you* ^__^
 But let's get to the basics first!

What is lateral medullary syndrome?
Neurological symptoms due to injury to lateral part of the medulla.
Also called Wallenberg's syndrome.

When does it happen?
When the posterior inferior cerebellar artery is occluded.

What is lateral pontine syndrome?
Neurological symptoms due to injury to lateral part of the pons.

When does it happen?
When the anterior inferior cerebellar artery is occluded.

Aniridia

What is Aniridia?
Aniridia is the absence of the iris

Viral inclusion bodies mnemonic

Free water clearance

Hi everyone!
This is my attempt of explaining everything I know about free water clearance.. Hope you understand :)

What is free water clearance?
Free water clearance (CH2O) is the volume of blood plasma that is cleared of solute-free water per unit time.

What does it mean? @_@
Water follows salt everywhere it goes.
[Think of salt and water as a lovey dovey couple, in a very codependent relationship of course, water being the lead role xP ]
