[Expanding Pharmacy Services for Sustainable Universal Health Coverage: Lessons from the Canadian Health Care System].

Japan's health care system can be regarded as one of the best worldwide, provided it remains sustainable. It has relatively low costs, short wait times, low disease incidence, and high life expectancy. However, universal coverage in Japan faces financial challenges due to the country's rapidly aging population.

Arginine carrier peptide bearing Ni(II) chelator to promote cellular uptake of histidine-tagged proteins.

Arginine-rich peptide-mediated protein delivery into living cells is a novel technology for controlling cell functions with therapeutic potential. In this report, a novel approach for the intracellular delivery of histidine-tagged proteins was introduced where a Ni(II) chelate of octaarginine peptide bearing nitrilotriacetic acid [R8-NTA-Ni(II)] was used as a membrane-permeable carrier molecule. Significant internalization of histidine-tagged enhanced green fluorescent protein (EGFP) into HeLa cells was observed by confocal microscopic observation in the presence of R8-NTA-Ni(II).
