In this work, the electromagnetic scattering from an arbitrary conducting target above the PM sea surface is studied by a hybrid method combining the finite element method (FEM) with the boundary integral equation (BIE). As the integral boundary can be set at anywhere with the arbitrary shape, the conformal truncated boundaries are built to reduce the(More)
Antisera were raised against synthetic peptides derived from the primary amino acid sequence of human chromogranin B. These antisera recognized in one- and two-dimensional immunoblotting a component previously designated as chromogranin B. In human chromaffin granules, the major endogenous processing product of chromogranin B is formed by proteolytic(More)
Although existing data suggest an influence of leptin on circulating levels of growth hormone (GH), the action site and properties of leptin are still controversial. Using primary cultured ovine pituitary cells, we studied the direct effect of leptin on the secretion of GH. Pituitary cells were dissociated by collagenase and subjected to Percoll gradient(More)
BACKGROUND Pemphigus is an organ-specific autoimmune bullous disease. OBJECTIVES To determine the role of regulatory B cells (Bregs) in patients with pemphigus. METHODS The frequency of the occurrence of CD19(+) CD24(hi) CD38(hi) Bregs was detected from 34 patients with pemphigus and 20 healthy controls. Interleukin (IL)-10 secretion was processed after(More)
Heparin-modified hydroxyapatite (HAP-HP) particles were prepared by an in situ coprecipitation method and were characterized by Fourier transform infrared spectrometry, x-ray diffraction and transmission electron microscopy. The heparin content in the particles was determined by a colorimetric assay and energy dispersive x-ray spectroscopy. Final results(More)
