background: usual dosage  of morphine  (10 mg/kg) induces  analgesia  and ultra-low dose (uld) of morphine (1 μg/kg); hyperalgesia, and  c-fibers are also bearing  μ- opioid receptors; here the importance  of c-fibers on pain and  morphine   induced  analgesia/hyperalgesia  is questioned   and  investigated    using   pain   evaluation methods and infant capsaicin treating  for c-fibers lesioni...

waveguides with low confinement loss, low chromatic dispersion, and low nonlinear effects are used in optical communication systems. optical fibers can also be employed in such systems. besides optical fibers, photonic crystal fibers are also highly suitable transmission media for optical communication systems. in this paper, we introduce two new designs of index-guiding photonic crystal fiber ...
