- Ep. 69 Gut Ulcers! (And Stress?)
This episode is about peptic ulcers, the ulcers of your stomach and duodenum. For a long time they were considered to be linked to stress, but that idea fell a little out of favor when H. pylori bacteria were discovered as a major causative agent for gastritis. But in more recent years, stress and its connection to peptic ulcers are making a bit of a comeback!

52 min - [CORRECTED] Ep. 66 Stress: The HPA Axis of Evil
This is a corrected version of the episode! The audio from the last release was all messed up! Sorry about the mistake!
Are y'all done feeling stressed yet? No? Well neither are we! We continue our discussion from last episode, moving on to the stuff that actually makes the stress hormone, the HPA axis! What does the hypothalamus-pituitary-adrenal axis do and how does it work? Also, we discuss what the science is behind stress vis-a-vis hair loss and hair greying!

40 min - Ep. 64 The BBB2: The Crack in the Wall
Last episode introduced the blood brain barrier; it is a lot like a bouncer for the exclusive dance club that is your brain, keeping all the randos out. But this week we get into some of the details on diseases and drugs and their impact on the blood brain barrier. Also, sometimes we WANT drugs to get into the brain, so how can we get around this BBB?

1 hr 4 min - Ep. 63 The Brain's Bouncer: The Blood Brain Barrier
We did a twitter poll and the people have spoken! You folks want to hear about the "Blood Brain Barrier"! But what is it, besides great alliteration?! The blood brain barrier is a lot like a bouncer for the exclusive dance club that is your brain -- but who is allowed in? How does one get in? And on a cellular and protein level, who are the actual bouncers that keep us out? Next week we will get into some of the details on diseases and drugs and their impact on the blood brain barrier, so tune in next week too!
