By inference, we conclude that this delayed settlement is an unavoidable timing error that desynchronizes the development of neocortex and thalamus, and arrests the outgrowth of axonal projections by GPT neurons.
After two treatments on E12, ablated mice terminated on E14 had a 54% reduction due to unablated GPT neurons generated on E11, absence of GPT neurons killed on E12 (45%) and delayed settlement of GPT neurons normally generated on E13 (10%).
GPCRs and membrane trafficking mechanisms that are expressed in the larval stages are candidate regulators of competence and metamorphosis, and indeed, exposure of precompetent larvae to an inductive cue results in habituation or a decrease in responsiveness that delays settlement [ 13].
The delayed settlement and tight packing of a near-normal complement of GPT neurons into this smaller ablated neocortex merely emphasize the presence of the middle lamina of principal PP neurons as usually found during its immature stage (Luskin and Shatz, 1985; Xie et al., 2009).
After four treatments on E11 E12, ablated mice terminated on E14 had a 56% reduction due to replacement of GPT neurons killed on E11, absence of GPT neurons killed on E12 (45%) and delayed settlement of GPT neurons normally generated on E13 (10%).
A House subcommittee has approved a bill to ban such "pay-for-delay settlements".
"He's done really aggressive work to stop these pay-for-delay settlements," she said, referring to drug industry practices.
The F.T.C. found that there have been more such pay-for-delay settlements in the first nine months of the current fiscal year than in any entire previous year.
One tactic that insurance companies use, they say, is to put off paying for as long as possible, by delaying settlements and stalling court procedures brought against them by frustrated policyholders.
Jon Leibowitz, chairman of the Federal Trade Commission, which has greatly increased its scrutiny of what it calls "pay-for-delay settlements" between generic and branded drug companies, said that the appeals court decision "puts us one step — and a very important one — closer to solving this very real problem".
