Fingernail Configuration
BACKGROUND A number of conditions can alter a person's fingernail configuration. The ratio between fingernail width and length (W/L) is an important aesthetic criterion, and some underlying diseases can alter the size of the fingernail.

Genetic analysis using fingernail DNA.
For the genetic analysis with the polymerase chain reaction (PCR), template DNA is generally prepared from blood cells. However, in some instances, when blood samples are not available, DNA from hair can be used for the analysis (1, 2). Both mitochondrial DNA (mtDNA) and nuclear DNA can be amplified using DNA extracted from one hair. While hair sampling is easy, there are still some problems, e...
متن کاملFingertip Force Measurement by Imaging the Fingernail
Shear and normal forces from fingertip contact with a surface are measured by external camera images of the fingernail. Due to mechanical interaction between the surface, fingertip bone, and fingernail, regions of tension or compression are set up that result in reddening or whitening due to blood flow. The effect is quantitative enough to serve as a transducer of fingertip force. Due to indivi...
