Analysis of Biological Elements of Scalp Hairs with SEM-EDX and TEM and Its Application to Hair Comparison

    S. Seta
    TLDR SEM/EDX can analyze hair elements but struggles with trace elements, limiting its forensic use.
    The study explored the use of scanning electron microscope equipped with energy dispersive X-ray microanalyzer (SEM/EDX) for the elemental analysis of hair samples in forensic investigations. While traditional methods relied on morphological features and ABO blood typing, SEM/EDX offered a way to analyze trace elements in hair, which could aid in personal identification. However, the technique faced limitations in detecting trace elements other than sulfur and chlorine from raw hair samples, highlighting a challenge in its application for hair comparison in forensic contexts.

      community Verteporfin and Microneedling

      in Treatments 1 year ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
