Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.
research A Discourse on Human Hair Fibers and Reflections on the Conservation of Drug Molecules
Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.
research Characterization and Chromosomal Localization of Human Hair-Specific Keratin Genes and Comparative Expression During the Hair Growth Cycle
Two specific hair keratin genes are active during hair growth and decline as hair transitions to rest.
research Microscopical Characterization of Known Postmortem Root Bands Using Light and Scanning Electron Microscopy
The research found that postmortem root bands in hair are likely caused by the breakdown of a specific part of the hair's inner structure after death.
