So I’m trying really hard to get back into super hardcore studying mode after two whole days of absolutely no studying because of my bout with food poisoning. As if it wasn’t already hard enough because I’m still not 100% better yet (try feeling up to studying when the only things you’ve ingested in the last two days have been a smoothie and some french fries and suffering from perpetual orthostatic hypotension because of dehydration), my physiology book just has to make even the simplest concept hard to understand. Really, these are things that I understood before when I learned them in class and even from other physiology books, but I can’t understand them when I read them in this one. Why am I using this book then? Because it’s a grad school level book and I just can’t use a med school level book to study for my quals because those are just way too over-simplified (try telling that to a med student). Seriously, let’s explain minimum systemic filling pressure by doing a thought experiment involving replacement of the heart and lungs with a simplified pump?! Why can’t I just imagine the heart stopping and pressures equilibrating across all components of the circulatory system? Is it really that hard to keep it simple? And then there was the most annoying section on vasoactive substances that function in the intermediate and long-term control of the circulation, where they chose to list a bunch of things, like endothelins, prostaglandins, and nitric oxide, but then proceeded to state that their roles in blood pressure homeostasis are questionable. Then why, oh why are they listed in this section?! Argh! Am I too dumb? Is my mind still, after all these years in grad school, stuck in med student mode? Or do I just need more sleep/food? Whatever it is, it sure makes me feel like I’ll never be ready for my quals. And that really freaks me out.

» Yum!  Now that’s something I can live with: eating curry to stave off cognitive decline and Alzheimer’s disease.  Researchers in Singapore found that people (aged 60-93) who ate curry even only occasionally scored higher on the Mini Mental Status Exam (MMSE) than those who never ate curry.  The curry spice, turmeric, contains curcumin, which has potent antioxidant and anti-inflammatory properties.  And the prevalence of Alzheimer’s disease in the elderly in India is fourfold less than that in the United States. # 0

» There’s a great article today about how the MIT Dean of Admissions wants to reduce admissions anxiety in teenagers.  How about parents getting off of their kids’ backs?  That would help.  But I do admire her for trying to create a friendlier system that might just ease the pressure enough to not give parents such reason to push their kids so hard.  Too bad it probably won’t happen any time soon.  And go ahead and try to tell Asian parents to stop pushing their kids to the point of insanity.  I dare you. # 0
