    TLDR Researchers created an efficient method to extract DNA from marmoset hair, reducing blood chimerism.
    Researchers developed a non-invasive, partially automated method for extracting DNA from marmoset hair follicles to address the issue of blood chimerism in these primates. This protocol, which uses proteinase K and Promega’s Maxwell RSC system, was tested on samples from over 300 animals across two species. It successfully produced high-quality whole genome sequencing libraries from approximately 150 hair follicles, with low chimerism rates of 2.3% and an average duplication rate of 0.19. The method is efficient, scalable, and suitable for projects requiring low-input DNA sources or high-throughput processing. Data from the study are available in supplementary tables and archived online.

      Rotenone, a natural plant extract, may promote hair growth by increasing LDH activity and blocking MPC in the scalp, but it carries risks due to its toxicity. The suggested formulation includes Barbasco extract, DMSO, propylene glycol or PEG-400, ethanol, and a carrier oil.

      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.
