Abstract Purpose of Review Early enteral nutrition improves outcomes following traumatic brain injury (TBI). This can prove difficult due to TBI-induced feeding intolerance secondary disruption the brain-gut axis, a network composed central nervous system (CNS) input, autonomic signaling, and immunologic regulation that controls gut CNS homeostasis. Here, we discuss pathophysiology brain–gut ax...

We consider eigenvalue problems for dielectric cylindrical scatterers of arbitrary cross with generalized conditions at infinity that enable one to take into account complex eigenvalues. The existence resonance (scattering) frequencies associated these eigenvalues is proved. technique involves the determination characteristic numbers (CNs) Fredholm operator-valued functions constructed using Gr...

Callosal anomalies are frequently associated with other central nervous system (CNS) and/or somatic anomalies. We retrospectively analyzed the clinical features of corpus callosal agenesis/hypoplasia accompanying other CNS and/or somatic anomalies. We reviewed the imaging and clinical information of patients who underwent brain magnetic resonance imaging in our hospital, between 2005 and 2012. ...
