Article Synopsis
- A study was conducted to determine the reference range for 25-hydroxyvitamin D (25(OH)D) among healthy individuals in an urban area of Japan, as previous standard measurements have been lacking.
- Using a new liquid chromatography method to test serum samples, the researchers ensured accuracy and reproducibility of the results by comparing them to commercial assays.
- The findings showed that a staggering 98% of the 5,518 participants had inadequate vitamin D levels, suggesting lifestyle factors like limited outdoor activity and dietary choices contribute to this deficiency.
A simple device using magnetic transportation for droplet-based PCR.

October 2007
The Polymerase chain reaction (PCR) was successfully and rapidly performed in a simple reaction device devoid of channels, pumps, valves, or other control elements used in conventional lab-on-a-chip technology. The basic concept of this device is the transportation of aqueous droplets containing hydrophilic magnetic beads in a flat-bottomed, tray-type reactor filled with silicone oil. The whole droplets sink to the bottom of the reactor because their specific gravity is greater than that of the silicone oil used here.
