The parallel in-register assembly of prion protein monomers within the prion fibril, together with observed strain-dependent differences in fibril morphology, provide a structural foundation for understanding prion replication, strains, species barriers, and membrane pathogenesis.

Jul 21, 2019 · In addition, Bandler et al. 24 mentioned that, “SM techniques require sufficiently faithful coarse models to assure good results.” Thus, it is worth comparing the results (responses) of both coarse and fine models before applying the SM algorithm and starting the optimization process.

We found that FMRP binds mRNA encoding the voltage-gated potassium channel Kv3.1b in brainstem synaptosomes. To explore the regulation of Kv3.1b by FMRP, we investigated Kv3.1b immunoreactivity and potassium currents in the auditory brainstem ...

Gibbs • the algorithm • a bivariate example • an elementary convergence proof for a (discrete) bivariate case Neuralgic amyotrophy (NA), also known as Parsonage-Turner syndrome, is characterised by sudden pain attacks, followed by patchy muscle paresis in the upper extremity. Recent reports have shown that incidence is much higher than previously assumed and that the majority of patients never achieve full recovery. Traditionally, the diagnosis was mainly based on clinical observations and treatment ... This is the standard EM algorithm for normal mixtures that maximizes the conditional expected complete-data log-likelihood at each M-step of the algorithm. If desired, the EM algorithm may be replaced by an ECM algorithm (see ECM argument) that alternates between maximizing with respect to the mu and lambda while holding sigma fixed, and ...
