Local electrical conduction behaviors of polycrystalline La-doped BiFeO3 thin films have been investigated by combining conductive atomic force microscopy and piezoelectric force microscopy. Nanoscale current measurements were performed as a function of bias voltage for different crystal grains. Completely distinct conducting processes and resistive(More)
OBJECTIVE Study on the diagnostic accuracy of fine needle aspiration biopsy of cervical lymph nodes and to discuss the reasons of making a misdiagnosis. METHODS Five hundred and eighty cases of cervical lymph node fine needle aspiration biopsy were reviewed retrospectively. Among them, histologic findings were available in 161 cases. The cytologic and(More)
OBJECTIVE To study the association between single nucleotide polymorphisms(SNP) in toll-like receptors (TLR) 2 and 5 genes and the susceptibility to neonatal sepsis. METHODS One hundred and fourteen newborn infants who were diagnosed with clinical sepsis (case group) between May 2011 and January 2014 and 172 newborn infants without infection(control(More)
