Evaluation of anionic surfactants effects on the skin barrier function based on skin permeability.

Anionic surfactants are often used for cleaning and pharmaceutical purposes because of their strong surfactancy and foaming property. However, they are rarely ingested orally, the skin is a part of the human body most affected by surfactants. Barrier function of the skin is very strong, but the anionic surfactants can cause serious damages to it.

MHC matching improves engraftment of iPSC-derived neurons in non-human primates.

The banking of human leukocyte antigen (HLA)-homozygous-induced pluripotent stem cells (iPSCs) is considered a future clinical strategy for HLA-matched cell transplantation to reduce immunological graft rejection. Here we show the efficacy of major histocompatibility complex (MHC)-matched allogeneic neural cell grafting in the brain, which is considered a less immune-responsive tissue, using iPSCs derived from an MHC homozygous cynomolgus macaque. Positron emission tomography imaging reveals neuroinflammation associated with an immune response against MHC-mismatched grafted cells.

One confirmed and six suspected cases of cutaneous larva migrans caused by overseas infection with dog hookworm larvae.

Cutaneous larva migrans (CLM) is characterized as creeping eruption/serpiginous erythema and/or mobile erythematous induration on the skin. In Japan, Gnathostoma spp. are the most well known pathogens causing CLM, especially the creeping eruption type.
