  • Sizing of Final Stumps for Safer Pillar Extraction
    Sizing of Final Stumps for Safer Pillar Extraction
    08/01/2001 | NIOSH
    The risk of major pillar falls can often be reduced by leaving final stumps, large enough to protect the intersection but small enough to not inhibit gob caving. Analyses were conducted to assess factors on the size variation of remnant stumps.

    Interleukin-6 Treatment Augments Cutaneous Wound Healing in Immunosuppressed Mice
    Berry Ann K ;
    Gallucci RM
    2001/08/01 | National Institute for Occupational Safety and Health (NIOSH)
    It has been postulated that the inflammatory response that occurs after cutaneous wounding is a prerequisite for healing and that inflammatory cytokines, such as interleukin-6 (IL-6) are involved in this process. We showed previously that IL-6-deficient mice display delayed wound healing, which could be reversed by administration of a murine IL-6 e ...
