Hi, do you know any studyblrs that study anesthesiology or medical in general? Thank you!

Hey! Active anesthesiology studyblrs I only found this lovely:

Rare babe!

Here are some active medicine studyblrs:

Bonus: @dxmedicalstudent for amazing medical student related cartoons!

And active nurse studyblrs:

Bonus: @nursegif a BSN student with the funniest posts about nursing.

Please anyone else tag yourselves so I can add you!

23 year old aspiring photographer. College student, medical secretary, and Paparazzi consultant. I love love LOVE to read, so much so that I always have at least 2 books with me at all times. I also love to draw, although I’m not the best at it. I love a good comedy movie but also a good horror. And cartoons! Just looking for a new friend to talk to :)

Preferences: looking for female friends only.

Base of skull fractures can produce the clinical signs seen in my caretoon:

  1. ‘Raccoon eyes’ AKA periorbital bruising
    This is bruising around the eyes, sometimes seen with tarsal plate sparing; this is where the bruising doesn’t cover the upper eyelid, which contains the ‘tarsal plate’, a small area of connective tissue which helps stop the eyelid inverting when opening and closing the eye.
  2. Blood or CSF rhinorrhoea (nose leakage) and otorrhoea (ear leakage)
    These fluids may leak from the nose or ear. CSF is cerebrospinal fluid; the clear fluid which surrounds the brain and spinal cord.
  3. Haemotympanum
    This is blood seen behind the eardrum (AKA tympanic membrane) when using an otoscope, the tool a doctor uses to look inside the ear canal.
  4. ‘Battle sign’ AKA postauricular bruising
    Bruising may appear behind the ear.

These clinical signs occur in base of skull fractures, when the cracked bone, or trauma that caused it, results in damage to the blood vessels or/and brains covering, allowing leakage of their contents into these areas of the head and neck.

They make up a classic set of signs emergency doctors will look for when assessing patients who have had a head injury. They can be a marker of how severe the trauma has been, and alert medics to consider further imaging (scans) to go looking for further damage or compromise to structures within the skull.

These signs are important ‘free information’ to pick up if you have a sharp eye!

Avatars Involved 
Oklahoma, CEO, Washington and Minnesota. 

Character Notes:
Minnesota is the doctor for the states (because Mayo clinic), and Oklahoma handled medical insurance because *hand waves* reasons that are not at all related to mistaking life insurance companies for medical insurance companies, but I sorta liked him doing that, so I kept it. 

Washington’s condition is meant to reflect Mount St Helens

History Notes:
Not so much history, but current event and actually my life. 
Literally, this is what my oncologist told me insurance companies did when he was trying to explain why my PET scan might be delayed until May. He (angrily) explained Doctors now needed insurance approval to schedule the PET scan (otherwise they rejected the claim and I’d have to pay the full amount out of pocket), and because it was so near the end of April, and this no longer looked to be pancreatic cancer, but “only” Lymphoma, they might not approve the PET scan until May, so that they could report higher profits in April. He explained they liked to play the “how much profit can we make before we are really endangering the patient” and since my tumor had no markers for aggressive cancer I may have to wait -_-


Btw, this is why the comic was on hiatus. Cancer Scare. 
Still ongoing, still waiting on biopsy results, but scary aggressive cancer has been ruled out, so not it just maybe lazy indolent tumor, autoimmune, or many other things I am waiting on a biopsy to find out.

The interactions between Nonpolar molecules and Water molecules are not as favorable as interactions amongst just the water molecules, due to the inability of nonpolar molecules to form hydrogen bonding or electrostatic interactions.

When nonpolar molecules are introduced to the water molecules, the water molecules will initially surround the nonpolar molecules, forming a “cages” around the molecules. However, the tendency of nonpolar molecules to associate with one another will draw the nonpolar molecules together, forming a nonpolar aggregate.

Based on the second law of thermodynamics, the total entropy of the system plus its surrounding must always be INCREASING. Therefore, it is Favorable for the nonpolar molecules to associate without the interference of water. The water molecules that initially “caged” the nonpolar molecules are released from the nonpolar molecules’ surfaces, creating an Increase in Entropy in the surrounding (increase in disorder). The favorable release of water molecules from nonpolar surfaces is responsible for phenomenon of the hydrophobic effect.

When two nonpolar molecules come together, structured water molecules are released allowing them to interact freely with bulky water. The release of water from such cages is favorable. The result is that non-polar molecules show an increased tendency to associate with one another in water compared with others - less polar and less self-associating solvents. This tendency is called the hydrophobic effect and the associated interactions are called hydrophobic interaction.

The release from the cage-like clathrates is more favorable because it increases the entropy of the system.

Hydrophobic interactions can also be seen in the clustering of amphipathic/amphiphillic molecules such as phospholipids into bilayers and micelles. The hydrophobic areas of amphipathic molecules cluster together to avoid the ordered “cage” of water molecules that would surround them and orient the hydrophillic ends as a shield-like outer structure that interacts amicably with the polar water molecules.

Micelles occur when a spherical fatty acids structure is formed with a hydrophobic core and hydrophillic outer shell.

Bilayers can be commonly seen in cell membranes with hydrophillic outer (outside the cell) and inner (inside the cell) linings has hydrophobic (inside the membrane) center.

The Lipid bilayer is a more favored formation in nature due to the micelle formation may contain bulky fatty acids causing hindrance in its formation.

Most cell membranes are electrically polarized, such that the inside is negative [typically 260 millivolts (mV)]. Membrane potential plays a key role in transport, energy conversion, and excitability.
For example, membrane transport. Some molecules can pass through cell membranes because they dissolve in the lipid bilayer.
Additionally, most animal cells contain a high concentration of K1 and a low concentration of Na1 relative to the external medium. These ionic gradients are generated by a specific transport system, an enzyme that is called the Na1–K1 pump or the Na1–K1 ATPase.
The hydrolysis of ATP by the pump provides the energy needed for the active transport of Na1 out of the cell and K1 into the cell, generating the gradients.

The pump is called the Na1–K1 ATPase because the hydrolysis of ATP takes place only when Na+ and K+ are present. This ATPase, like all such enzymes, requires Mg2+
