Mixed Block Notes 5 Flashcards
FA vs Glucose oxidation in ATP generation and O2 use
FA oxidation produces more ATP, but uses more O2 per ATP
Receptor mediating Mydriasis
Alpha 1
Receptor mediating uterine relaxation
Beta 2 (tocolysis = Terbutaline, Ritodrine)
Mom and infant sequelae of rubella
Mom = Polyarthritis/Polyarthralgia; Infant = Sensorineural deafness, Cataracts, Cardiac malformations (PDA)
Intracellular pyrophophate granules in a bug
C diph (methylene blue staining)
Conus Medullaris Syndrome
L2 lesion = Flaccid paralysis of bladder and rectum, impotence, saddle anesthesia
Cauda Equina Syndrome
Radiating back pain, Saddle anesthesia, Loss of anocutaneous reflex, Bowel and bladder dysfunction, Loss of ankle-jerk reflex w/ plantar flexion weakness
Saddle anesthesia and Loss of anocutaneous reflex =
S2-S4 lesion (cauda equina syndrome)
Danazol MOA
Synthetic androgen for endometriosis and hereditary angioedema
Mifepristone MOA
Synthetic steroid with anti-progestin and anti-glucocorticoid effects
Mitotane MOA
Adrenocorticolytic used primarily for adrenocortical carcinoma
Maintenance Dose =
Cpss x CL / [Bioavailability fraction]
Half life =
(Vd x 0.7) / CL
Loading Dose =
(Vd x Cpss) / [Bioavailability Fraction]
Methoxamine MOA
Selective a1 agonist
a2 activation effects
Decr insulin, Decr lipolysis, Decr aqueous humor production, Incr Platelet Aggregation
b1 activaiton effects
HR/Contractility, Incr Renin and Lipolysis
b2 activation effects
Vasodilation/Bronchodilation; Incr Lipolysis and Insulin; Decr uterine tone; Ciliary muscle relaxation and acqueous humor production
Recurrent kidney stones in young patient indicates
Inborn error of metabolism
Sodium Cyanide-Nitroprusside test
Detects presence of (sulfhydryl groups) urine cystine (converts cystine to cysteine and nitroprusside binds to make purple)
Treatment of Cystinuria
Hydration and Alkalinization of urine
Microscopic finding of irreversible cardiac ischemic injury
Vacuoles and Phospholipid-containing amorphous densities w/in mitochondria
Glandular epithelial changes from Proliferative to Secretory stages in endometrium
Pseudostratified, elongated, mitotically active epithelial cells –> Acquire large cytoplasmic vacuoles
Features that differentiate LEMS from MG
Hypo/areflexia, Autonomic symptoms, Classic incremental response to repetitive stimuli
Pyruvate Carboxylase activity is increased by
Acetyl-CoA
Citrate is a regulator of
Positive regulator of AcCoA Carboxylase, F-1,6-BP; Negative of PFK1 and 2 (inhibiting glycolysis)
Narcolepsy with Cataplexy is most often caused by
Lack of Hypocretin 1/2 (Orexin A/B) from Lateral Hypothalamus
Elevatd 14-3- protein in CSF
CJD
