Opsoclonus-myoclonus syndrome (OMS) is a rare neurological disorder characterized by a combination of main symptoms: opsoclonus, myoclonus, ataxia, psychoemotional and behavioral disturbances. OMS can develop in children as a result of immunopathological processes against the background of infectious or oncological pathology and lead to persistent neurological deficit. A case of ten-year observation of paraneoplastic OMS associated with neuroblastoma in a child is presented.

Nevertheless, weak inherent nonlinearity of conventional optical materials continues to hinder the progress of a number of important applications. In this study, we delve into the realm of broadband enhancement of nonlinearity within one-dimensional (1d) plasmonic metamaterials, exploring its intricate connection with nonlocality.

The use of EMHPS in the complex therapy of the above diseases may cause the development of drug-drug interactions, particularly pharmacokinetic interactions at the level of transporter proteins. In the present study, we evaluated the interaction of EMHPS with ABCB1 and SLCO1B1.
