How long should I keep records?

The period of limitations is the period of time in which you can amend your tax return to claim a credit or refund, or that the IRS can assess additional tax. The below information contains the periods of limitations that apply to income tax returns. Unless otherwise stated, the years refer to the period after the return was filed. Returns filed before the due date are treated as filed on the d...

How Long to Keep the Surgical Drains- Looking for Evidence

Head and neck operations are associated with clinically significant postoperative morbidities such as haematoma, seroma, wound infection and skin flap complications [1]. Closed suction drainage is the standard of care for Head and Neck surgical wounds. The purpose of drains is to obliterate dead space and to reduce seroma and hematoma formation, thus improving skin apposition and wound healing,...

Narrow pore-diameter polypyrrole nanotubes.

Bulk quantities of electrically conducting nanotubes of polypyrrole having narrow pore diameter (6 nm) can be synthesized rapidly by chemical oxidative polymerization of pyrrole in the presence of stoichiometric amounts of V2O5 nanofibers. The V2O5 nanofibers act as templates for polymerization and yield, as the initial product, polypyrrole nanotubes with pores filled with V2O5. The V2O5 dissol...

Long live the pore

n the first in vivo characterization of nuclear pore complex (NPC) dynamics in mammalian cells, Daigle et al. (page 71; see also the Comment on page 17) have found that NPCs are remarkably stable complexes that appear to be anchored to a protein network in the nuclear envelope. The work also demonstrates the feasibility of tracking single protein complexes in living cells. By fusing GFP tags to...
