The relation between health literacy, hypertension knowledge, and blood pressure among middle-aged Japanese adults.

Background: With the growth in the popularity of the Internet, individuals' skills in finding and applying information about health issues [health literacy (HL)] are affecting their health behaviors. This study aimed to examine functional HL (FHL), critical HL (CHL), and hypertension knowledge (HK) among middle-aged Japanese adults. In addition, to measure health outcomes, we examined the relationship between HL, HK, and blood pressure (BP) level.

Visible-light induced hydrogen production using a polypeptide-chlorophyll complex with alpha-helix conformation.

Hydrogen production was accomplished under visible-light irradiation by using a system consisting of a biomolecule (chlorophyll a), methylviologen, ethylenediaminetetraacetic acid disodium salt and Pt-loaded poly(l-glutamate) (Poly(Glu)), in aqueous decylammonium chloride (DeAC) solution. Spectroscopic studies revealed that chlorophyll a is solubilized in the hydrophobic clusters of Pt-loaded Poly(Glu)-decylammonium chloride. In the Poly(Glu)-DeAC complex, the electron transfer occurred between chlorophyll a and methylviologen leading to hydrogen production.
