Different Contacted Cell Types Contribute to Acquiring Different Properties in Brain Microglial Cells upon Intercellular Interaction.

Microglial cells (MGs), originally derived from progenitor cells in a yolk sac during early development, are glial cells located in a physiological and pathological brain. Since the brain contains various cell types, MGs could frequently interact with different cells, such as astrocytes (ACs), pericytes (PCs), and endothelial cells (ECs). However, how microglial traits are regulated via cell-cell interactions by ACs, PCs, or ECs and how they are different depending on the contacted cell types is unclear.

Assessment of circulating microRNA specific for patients with familial adenomatous polyposis.

Circulating microRNAs (miRNAs) are considered promising biomarkers for diagnosis, prognosis, and treatment efficacy of diseases. However, usefulness of circulating miRNAs as biomarkers for hereditary gastrointestinal diseases have not been confirmed yet. We explored circulating miRNAs specific for patients with familial adenomatous polyposis (FAP) as a representative hereditary gastrointestinal disease.

The experience of parents of adult sons with Duchenne muscular dystrophy regarding their prolonged roles as primary caregivers: a serial qualitative study.

Purpose: Mechanical ventilation has allowed a greater number of patients with Duchenne muscular dystrophy (DMD) to transition into adulthood. However, the role of a child's parent as a caregiver lasts throughout the child's lifetime. We explored parents' experiences of prolonged caregiving using serial interviews, analyzed using constructivist grounded theory.

Drug Permeation Characterization of Inhaled Dry Powder Formulations in Air-Liquid Interfaced Cell Layer Using an Improved, Simple Apparatus for Dispersion.

Purpose: An improved, simple apparatus was developed to easily and uniformly disperse dry powders onto an air-liquid interfaced cultured cell layer. We investigated drug permeation in cell cultures with access to the air-liquid interface (ALI) following deposition of a dry powder using the apparatus.

Method: The improved apparatus for dispersing the powders was assembled.
