10 Flashcards
Anti-thombin III deficiency (Bagel Lady)
AD
- Venous thrombosis
- Hypercoagulable state
“cotton candy” on pap smear; incidental finding in patient with intrauterine device
Actinomyces-like organisms
squamous cells covered with rods to obscure normal epithelial margins
Clue cells
Beta (1,3) glycan is a main component in
Candida and Aspergillus cells walls (Caspofungin)
Chronic Alcoholic and receptors (leads to tolerance)
UP-REGULATION of NMDA
DOWN-REGULATION of GABA
Most common INITIAL FINDING of alcohol withdraw
The shakes (tremors)
Fluctuating arousal levels are characteristic of delirium tremens. When do you see this?
48-96 hours of last drink
Kinda confusing but you are seeing hallucinations here too kinda seems like there is overlap in stages
Childhood to puberty…status of dat oocyte?
Meiosis I arrested in PROPHASE
Status of that oocyte after ovulation
Meiosis II arrested in metaphase
Why is prophase of meiosis II unique?
does not immediately follow a period of DNA synthesis; DNA was duplicated prior to prophase of meiosis I
How does metaphase of meiosis I different form metaphase of meiosis II and mitosis
Spindles not preparing to split the centromere
Tetrads instead lined up along the metaphase plate, and during anaphase the homologs separate from each other the the centromeres intact
Type of DNA cloning were signals nec. for transcription and translation are included in the cloned DNA. Allows for bacteria to be used to produce large amounts of proteins of interest
Expression cloning
TFs, thyroid proteins, steroids, Vit. D receptors, retinoic acid receptors, DNA transcription and replication proteins,
all bind DNA (good for plasmid vector shit)
Isotype switching is a process that occurs in naive B-lymphocytes on initial exposure to antigen. Walk me through how it happens
CD40 (on B-cell) binds CD40L on T-helper cells.
IL-4 secreted by TH cell = IgE switch
IL-5 secreted by TH cell = IgA swtich
Defect in CD18
LAD
Inherited defects involving the _______ signaling pathway result in disseminated mycobacterial disease in infancy or early childhood.
Interferon-gamma signaling
Fastest metabolism in glycolytic pathway?
Fructose=Fastest
Dietary fructose is phosphorylated in the liver to F1P and is rapidly metabolized because it bypasses _______, the major rate limiting enzyme of glycolysis
PFK-1
Obstructive hydrocephalus (aqueductal stenosis-> papilledema, HA, vomiting) and DORSAL MIDBRAIN (PARINAUD) SYNDROME
Pineal gland mass/tumor
DORAL MIDBRAIN (PARINAUD) SYNDROME
paralysis of upward gaze, ptosis, and pupillary abnormalities
due to direct compression of pretectal region of midbrain
(ex: pineal mass)
What is the most common pineal mass?
germinoma (a midline malignant tumor thought to arise from embryonic germ cells)
Germinoma also in suprasellar region (endocrinopathies) balls and mediastinum (young boys)
Damage, tumor, infact/hemorrhage of thalamus
Contralateral hemisensory loss, behavioral changes and language deficits
Gait and limb ataxia, intention tremor, and nystagmus in a child
Medulloblastoma (cerebellum)
Contralateral loss of pain and temp
Ipsilateral paralysis of CNs V, IX, X, and XI
Lateral Medullary (wallenberg syndrome)
