The results showed that the optimal drying condition was 376.1 W for 3 min, 282.1 W for 3 min, 188 W for 9 min, and 94 W for 3 min. The thiosulfinates retention after drying was 90.2%. Following drying, the garlic powder was microencapsulated by modified fluidized bed technique. Scanning electron microscope revealed good integrity and core materials that were embedded in the microcapsules. Studies on the release kinetics of microencapsulated garlic granulates in vitro using simulated intestinal fluid indicated that release of garlic powder could be controlled in the intestine by passing stomach conditions.展开更多
VSIG4(the protein V-set and immune globulin domain-containing 4)是一种与巨噬细胞蛋白质相关的新的B7相关免疫球蛋白的Ⅰ型跨膜蛋白,具有抑制T细胞活化的能力,也被称为CRIg(免疫球蛋白超家族)和Z39Ig,在病原体识别和清除中起关键...VSIG4(the protein V-set and immune globulin domain-containing 4)是一种与巨噬细胞蛋白质相关的新的B7相关免疫球蛋白的Ⅰ型跨膜蛋白,具有抑制T细胞活化的能力,也被称为CRIg(免疫球蛋白超家族)和Z39Ig,在病原体识别和清除中起关键作用。恶性肿瘤中,VSIG4的表达及VSIG4阳性T细胞的增加可能预示更高的侵袭性和复发风险。全文就VSIG4与各肿瘤间的关系作一简要概述,为VSIG4与恶性肿瘤诊治提供参考。展开更多
