OBJECTIVES To determine the utility of two-dimensional (2D) sonographic placental measurements in the prediction of small-for-gestational-age (SGA) infants. METHODS The maximal diameter along the fetal surface of the placenta and the maximal placental thickness were measured at 18-24 weeks' gestation, and the measurements repeated in the orthogonal plane.(More)
Intracranial clear cell meningioma (CCM) is very rare and often has an aggressive clinical course. The predilection site of intracranial CCM in children was cerebellopontine angle where represents challenging tumor resection because of the vicinity of brainstem, vertebral artery, and lower cranial nerve. Therefore, special consideration is required for this(More)
An efficient Ag-catalyzed three-component reaction of amidines, ynals, and alcohols, phenols, or water has been developed. This strategy provides a wide range of substrates and represents a simple process for the preparation of different imidazole derivatives in good yields with high regioselectivities.
