Hemodynamics of the left cerebral hemisphere during silent reading:analysis using near-infrared spectroscopy.

The purpose of this study was to investigate the hemodynamic activity in the left cerebral hemisphere during silent reading in college students with typical development using near-infrared spectroscopy (NIRS). Sixty college students with typical development participated in this study. In the silent reading task, participants were asked to read a text from Andersen's fairy tale.

A female case of L1 syndrome that may have developed due to skewed X inactivation.

Background: Heterozygous L1CAM variants cause L1 syndrome with hydrocephalus and aplasia/hypoplasia of the corpus callosum. L1 syndrome usually has an X-linked recessive inheritance pattern; however, we report a rare case occurring in a female child.

Case Presentation: The patient's family history was unremarkable.

Identification of polyethylene glycol-resistant macrophages on stealth imaging in vitro using fluorescent organosilica nanoparticles.

An in vitro imaging system to evaluate the stealth function of nanoparticles against mouse macrophages was established using fluorescent organosilica nanoparticles. Surface-functionalized organosilica nanoparticles with polyethylene glycol (PEG) were prepared by a one-step process, resulting in a brush-type PEG layer. A simultaneous dual-particle administration approach enabled us to evaluate the stealth function of nanoparticles with respect to single cells using time-lapse fluorescent microscopic imaging and flow cytometry analyses.
