    Recoloring hair is not Harris’s end goal. Sure, her work has applications to pigmentary disorders like the autoimmune disease vitiligo and to the most common skin cancer, melanoma, which is cancer of the melanocyte cells. But ultimately, she wants to understand why somatic stem cells — which are found in muscles, bone and organs throughout the body...

    “Everyone gets gray hair,” Harris said. But hair-graying research has a bad reputation that keeps many investigators away. “It is considered vanity science,” Harris said. As she likes to emphasize during her talks, however, “I am not an abnormally vain person,” she insists. “My lab has picked the model that is the most appropriate method to investi...

    Harris and one of her doctoral students, Joseph Palmer, suspect that one way in which melanocyte stem cells might be affected with age has to do with a phenomenon called the “quiescence program.” Most types of stem cells are needed only sporadically, to replace a specialized population of cells — such as the melanocyte stem cells, which are called ...

    The immune angle had turned up a few months earlier in an unexpected way. Spanish physicians writing in JAMA Dermatologynoted a strange side-effect in more than a dozen patients receiving anti-programmed death receptor ligand 1 (anti-PD-L1) immunotherapy as treatment for lung cancer: hair repigmentation. PD-L1 is a protein that suppresses the immun...

    The Harris lab looked at quiescent melanocyte stem cells and found that they expressed more of the PD-L1 protein than actively dividing cells. “And as you go farther into quiescence, cells are expressing more PD-L1, and they are harder to reactivate when Joseph gives them cues to say, ‘Hey, wake up!” Harris said. The research has convinced Harris t...

This method has the advantages of simplicity and safety, but does not freeze the tissue as rapidly as immersion in a freezing medium. The method we prefer uses dry ice in pellet form.

Experts from the University of Alabama at Birmingham discuss changes starting in March 2020 that will forever stamp and change our lives. “We’ve had to shift the way we approach most things in our lives,” said ...

  6. 2022年10月14日 · Small cavities are manageable now without drilling away the tooth structure, thanks to resin infiltration, a technique to fill cavities at an early stage. “This is one of the neatest things, which just has not made it into the public consciousness yet, for whatever reason,” Lawson said. “A clear resin is injected into the tooth and fills ...
