P-selectin mediates adhesion of the human melanoma cell line NKI-4: identification of glycoprotein ligands

Activated endothelial cells and stimulated platelets express the cell adhesion molecule P-selectin (CD62P), which mediates adhesion to various leukocytes and certain types of cancer cells. In this study, we show Ca2+-dependent binding of P-selectin to NKI-4 cells, a cell line derived from a human melanoma. The binding is inhibited by P7 (a leukocyte adhesion blocking mAb against P-selectin), but not by PL5 (a leukocyte adhesion blocking mAb against P-selectin glycoprotein ligand-1; PSGL-1). Further, expression of PSGL-1 could not be detected on NKI-4 cells by either PL5 mAb or an Ab against a synthetic peptide corresponding to a portion of the PSGL-1 sequence. P-selectin affinity chromatography of lysates from in vivo [3H]-glucosamine-labeled NKI-4 cells resulted in the isolation of three glycoproteins, with apparent molecular masses of approximately 250, approximately 110, and approximately 100 kDa under reducing conditions and approximately 230, approximately 105, and approximately 85 kDa under nonreducing conditions. These molecules could be precipitated by P-selectin, but not by E-selectin. EDTA and the P7 mAb, but not the PL5 mAb, inhibited the binding of P-selectin to the purified ligands. Surprisingly, we found that sodium chlorate, a sulfation inhibitor, did not inhibit the binding of P-selectin to NKI-4 cells and that [35S]-sulfate did not label the NKI-4 cell ligands. We conclude that P-selectin-dependent adhesion of the human melanoma cell line NKI-4 is mediated by a novel class of glycoprotein ligands.

Example-based automatic music-driven conventional dance motion synthesis

We introduce a novel method for synthesizing dance motions that follow the emotions and contents of a piece of music. Our method employs a learning-based approach to model the music to motion mapping relationship embodied in example dance motions along with those motions' accompanying background music. A key step in our method is to train a music to motion matching quality rating function through learning the music to motion mapping relationship exhibited in synchronized music and dance motion data, which were captured from professional human dance performance. To generate an optimal sequence of dance motion segments to match with a piece of music, we introduce a constraint-based dynamic programming procedure. This procedure considers both music to motion matching quality and visual smoothness of a resultant dance motion sequence. We also introduce a two-way evaluation strategy, coupled with a GPU-based implementation, through which we can execute the dynamic programming process in parallel, resulting in significant speedup. To evaluate the effectiveness of our method, we quantitatively compare the dance motions synthesized by our method with motion synthesis results by several peer methods using the motions captured from professional human dancers' performance as the gold standard. We also conducted several medium-scale user studies to explore how perceptually our dance motion synthesis method can outperform existing methods in synthesizing dance motions to match with a piece of music. These user studies produced very positive results on our music-driven dance motion synthesis experiments for several Asian dance genres, confirming the advantages of our method.

The Synthesis of Covalent Triazine-Based Frameworks via Friedel–Crafts Reactions of Cyanuric Chloride with Thienyl and Carbazolyl Derivatives for Fluorescence Sensing to Picric Acid,Iodine and Capturing Iodine

A multifunctional thiophene-based covalent triazine framework (TTPATTh) with triphenylamine as core is synthesized by Friedel–Crafts reaction of cyanuric chloride with thienyl derivative for the first time. The yield of TTPATTh (99.59%) is far higher than that of the carbazole-based CTF (TTPATCz, 47.03%). TTPATTh and TTPATCz possess high BET surface areas with 1235 and 2501 m² g^–1 as well as high pore volumes with 1.60 and 2.23 cm³ g^–1, respectively. TTPATTh and TTPATCz have high thermal stability with high thermal decomposition temperatures of 514 and 598 °C in nitrogen atmosphere. With the introduction of triazine rings, the fluorescence sensing sensitivities of TTPATTh and TTPATCz to picric acid and iodine are improved significantly. Especially for TTPATTh, the K_sv values reach 5.95 × 10⁵ and 1.61 × 10⁴ L mol^–1, and LODs reach 1.02 × 10^–12 and 1.86 × 10^–12 mol L^–1. To the best of the knowledge, this is the most sensitive value among thiophene-based porous organic polymers to PA and I₂. Furthermore, TTPATTh and TTPATCz can also adsorb iodine in vapor phase, cyclohexane solution and aqueous solution, and release iodine by heating or in ethanol solution. The efficiency of controlling the release of iodine is higher than that in ethanol.
