Does narrow-band ultraviolet B radiation induce the expression of β-endorphin in human skin in vivo?
Our study is the first to show that UV-B exposures increase β-END expression in epidermal keratinocytes of human skin in vivo, which could be the link to proposed UVR addiction.
On conventional MRI, epidermoid-dermoid and arachnoid cysts have similar signal characteristics. Initial experience with spine DW imaging shows promise in differentiating epidermoid-dermoid cysts from arachnoid cysts. Preoperative differentiation is important because it changes management and surgical approach.
