A unique core-inversible micelle (CIM) was formed via PEG(5k)CA8 for hydrophilic drug delivery. An amyloid-fibril-inhibiting water-soluble molecule, congo red (CR), has been loaded into the hydrophilic core of CIMs. The targeting folate-CIMs significantly enhanced the intracellular delivery of hydrophilic CR in a folate receptor-expressing cell line.

BACKGROUND Previous studies showed that octacalcium (OCP) collagen composite (OCP/Col) can be used to repair human jaw bone defects without any associated abnormalities. The present study investigated whether OCP/Col could be applied to dental implant treatment using a dog tooth extraction socket model. METHODS The premolars of dogs were extracted; each extraction socket was extended, and tit...

Calcium-containing crystals are the most common class for the osteoarthritic joint. They are responsible for acute periarthritis and destructive arthropathies, and for tissue deposits mimicking tumor-like masses. These crystals encompassed mainly calcium pyrophosphate dihydrate and basic calcium phosphate crystals, with the latter being related to hydroxyapatite, carbonate-substituted apatite, ...
