Honeycomb reactor: a promising device for streamlining aerobic oxidation under continuous-flow conditions.

We report on the high potential of a honeycomb reactor for the use in aerobic oxidation under continuous-flow conditions. The honeycomb reactor is made of porous material with narrow channels separated by porous walls allowing for high density accumulation in the reactor. This structure raised the mixing efficiency of a gas-liquid reaction system, and it effectively accelerated the aerobic oxidation of benzyl alcohols to benzaldehydes under continuous-flow conditions.

MRI abnormality of the pulvinar in patients with status epilepticus.

Objective: Recently, magnetic resonance imaging (MRI) abnormalities of the pulvinar in patients with epilepsy have received greater attention, but their occurrence and features have not been fully elucidated. Therefore, we investigated the clinical and radiological features of patients with epilepsy who presented MRI abnormalities of the pulvinar.

Patients And Methods: We retrospectively investigated 225 consecutive patients who came to our institute because of seizures and underwent an MRI within 24h.

Magnetic resonance imaging investigation of secondary degeneration of the mesencephalic substantia nigra after cerebral infarction.

Secondary degeneration of the mesencephalic substantia nigra after cerebral infarction is widely known to occur in animal experiments, but has yet to be sufficiently investigated in human cerebral infarction. This study investigated the background and features of patients exhibiting secondary degeneration of the mesencephalic substantia nigra. The subjects comprised 43 patients admitted to our hospital for cerebral infarction between April 2007 and October 2010 showing secondary degeneration of the mesencephalic substantia nigra on cranial magnetic resonance imaging (MRI).
