beta blockers and diabetes
block the sympathetic response to low blood sugar;
nonselective beta blockers– use with caution (hypoglycemia)
equation for sensitivity
number of true positives/ total patients with the disease
how huntingtin suppresses other genes
histone de-acetylation
CMV shape and susceptibility
enveloped double-stranded DNA

esp. in patients with lung transplants
what is the significance of HLA-B*57:01 in AIDS patients?
avoid abacavir due to hypersensitivity reaction
what happens to RAAS in response to beta blockers

destruction of purkinje fibers that goes with cancers
trapezius muscle injury
drooping of shoulder
impaired abduction above horizontal
what do high concentrations of fructose 2,6 bisphosphate do?
inhibit gluconeogenesis
–> decreased conversion of alanine and other stuff to glucose

anaphylaxis with blood transfusion of O neg. What’s the likely dx?
selective igA deficiency can cause this.

short PR interval
widening of QRS interval
delta wave
can be associated with AV reentrant tachycardia and other arrhythmias
what extra thing should pts on inhaled glucocorticoids do?
oral rinsing to prevent candidiasis
how does alcohol serve as an antiseptic?
