Anorectal malignant melanoma: preoperative usefulness of magnetic resonance imaging.

Abstract：

:Magnetic resonance imaging (MRI) findings in three patients with primary anorectal malignant melanoma are described. Two patients had melanotic and one had amelanotic anorectal melanoma. The findings of MRI with a pelvic coil and an endorectal coil were consistent with pathologic findings. MRI with a pelvic coil demonstrated the melanotic component as high signal intensity on T1-weighted imaging. MRI with a pelvic coil and an endorectal coil was useful for staging anorectal melanoma. This article describes the initial report of the use of an endorectal coil for malignant melanoma of the anorectum.

  • STAT3 signaling within hepatocytes is required for anemia of inflammation in vivo.

    abstract：BACKGROUND:Anemia of inflammation, commonly observed in patients with chronic diseases, is associated with decreased serum iron. Hepcidin, mainly produced by hepatocytes in a STAT3- and/or SMAD-dependent manner, is involved in iron homeostasis. What remains to be established is whether or not the hepatic IL-6/STAT3 sig...
