Investigating the effect of host plant identity on instar number in fall webworm, a common generalist herbivore.

For herbivorous insects with a broad diet breadth, host plant identity can influence larval development by either accelerating or delaying growth. For some species of Lepidoptera, the number of larval instars varies depending on the host plant's identity. Fall webworm (Hyphantria cunea, Drury) is a polyphagous herbivore that feeds on over 450 host plants worldwide.

A simple method for non-denaturing purification of biotin-tagged proteins through competitive elution with free biotin.

The use of avidin or streptavidin in the purification of biotinylated proteins has been highly restricted due to the harsh and denaturing elution conditions. Here, we use biotinylated bovine serum albumin as a working model to demonstrate a simple and rapid method for biotin-tagged protein purification under non-denaturing conditions. The biotinylated bovine serum albumin is specifically bound to the anti-biotin antibody agarose beads and competitively eluted with free biotin under near-neutral conditions.

Delayed postoperative agitation in a child after preoperative midazolam.

We present a case report of a 5-year-old boy who had severe agitation after PACU discharge after midazolam premedication for minor otologic surgery. He was treated over several hours in the emergency department with several doses of midazolam and phenobarbital, without resolution of the agitation. Finally, a single dose of flumazenil (0.
