Everything (Week 4) Flashcards
What is order of C-PIB PET, PDG-PET, and brain atrophy and what stages of dementia do they correlate with?
C-PIB PET (complete) comes before FDG-PET (very mild dementia) which occurs before brain atrophy (mild dementia)
What are the 5 phases of abeta in different locations in the brain? What is functional correlation?
Phase 1: Abeta starts in neocortex - Nondemented
Phase 2: Entorhinal cortex - Nondemented (Abeta pyrogluamylated abeta and soluble abeta starts here and increased through other phases)
Phase 3: Hippocampus - Nondemented
Phase 4: Midbrain - Symptomatic (AbetapS8 starts here and icnreases in later phases)
Phase 5: Pons and cerebellum - Symptomatic
Explain the Dkk1 and canonical and noncanonical Wnt pathways, what two functions does Dkk1 control?
Dkk1 drives synapse loss and Abeta production in neurons (through canonical Wnt pathway by binding to Lrp5/6/Frazzled/Wnt and noncanonical pathway to drive APP/Vrgl2
What pathology does pyroglutamylated abeta correlate with?
Pyroglutamylated abeta (as measured by 8/4D antibodY) correlates with tau load in AD brains, but not general amyloid beta plaques (as measured by 4G8)
What size abeta oligomers can seed abeta plaques?
200-300 kDa, not 50-60 kDa
TREM2 variants (3) lead to what functional changes (4)?
TREM2 variants (R47H, R62H, T66M) lead to increased intracellular TREM2, reduced sTREM2, reduced microglial activation (measured by TSPO-PET), and no APOE upregulation or abeta engulfment
What type of antibody is Crenezumab? What patient population did it test in Phase 3 and 2? What doses?
Crenezumab - anti-amyloid beta IgG4 mAb (designed to bind Abeta oligomers, lack of vascular amyloid binding and low effector function backbone suggested as reasons for low ARIA risk), Phase III in prodromal or mild AD, Phase II in Mild-moderate AD; Phase III was 4x dose (60mg) as Phase 2 (15mg)
What is the method of focused ultrasound for BBB penetration?
Inject microbubbles and stimulate hippocampus with focused ultrasound to to loosen tight junctions to open BBB
VX-765 effect in AD mouse model?
Selective Casp-1 inhibitor leads to successful inhibition of cognitive deficits, inflammation and amyloid accumulation
When does sTREM2 increase and what pathology does it correlate with?
sTREM2 increases with aging (5 years before symptom onset) - strong correlation with tau but not Abeta
What does scopolamine do?
It blocks acetylcholine receptors and impairs short term memory in mouse model
What is the make up of the Series 65 test?
30% Legal and ethics issues
30% Client recommendations and investment strategies
25% Investment vehicles
15% Business and economic information
What is a security? (3)

What is authorized stock? How are number of shares determined?
The number of shares allotted in creation of the corporation. Number of shares are arbitrary, and new authorized stock needs to be approved for further money coming into the corporation.

- To maintain control of the company
- To increase earnings/share
- To use shares to pay for an acquisition/merger

What is book value and book value/share?
Book value = Total assets - Total liabilities (tangible)
Book value/share = Book value/outstanding shares
Par value
The value an accountant records in the balance sheet for sale of an initial stock
What are preemptive rights? Ensures through what? When and how can you purchase new shares? What is this called and what are the 3 possible outcomes?
Allows investors to maintain their ownership by buying percentage of shares, ensured through rights offering. You can buy percentage of shares at a discount for 45 days at subscription price. Possible outcomes:

What are equity security types (2)?
Common and preferred stock
Alzprotect
ALZ2006- binds cofactor of progranulin, entering Phase 2 in PSP
3 steps of a rights offering
- Once rights offering is declared, stock is traded with rights attached (trading cum rights) - starts trading cum rights after declaration date
- Stock becomes available to trade without rights attached after ex date (trading ex rights)
- Stock not sold in the rights offering is bought by underwriters (investment banks standing by)
The value of the common stock will be adjusted when and by what?
The value of the common stock will be adjusted down by the value of the right on the ex rights date
During a rights offering, one share = how many rights?
1 right
How is number of rights “cum rights” calculated and where is it detailed?
Stock price - Subscription price = Number of rights required to purchase one share + 1 That value (discount)/# of rights required for one share = value of one right Terms of how many rights required to purchase one additional share is detailed in terms of rights certificate
How is number of rights “ex rights” calculated?
Rights bought after ex date, stock price - subscription price = Number of rights required to purchase one share That value (discount)/# of rights = value of one right
What shares do underwriters purchase?
