Areas of Singapore
新加坡的五个区: Central / North/ North-East/ East / West
55个规划区: planning areas (PA/ DGP areas/ DGP zones)
女王镇（Queenstown）位于新加坡中西部，红山以西及金文泰新镇以东，名称取自英女王伊丽莎白二世，以纪念她在1952年加冕。女王镇距离核心商业区大约8千米（5.0英里），是新加坡最早发展公共房屋的社区，比起大巴窑和宏茂桥还要早。女王镇的前身被华族村民称为“无尾港”（福建话为 “boh beh kang”），因为在那里落脚的居民无法确定流往芳林山（Hong Lim Hill）和丰兴山（ Hong Heng Hill）这两座山的水源。
早于1950年代，新加坡改良信托局（Singapore Improvement Trust）已着手将女王镇打造成新加坡第一个卫星城市。大部分组屋均于第1个5年建筑计划（1960年–1965年）内建成，布局多为1至3房，楼层较低，而且没有装置升降机。

天然海绵
海绵（sponge）是动物界中最原始的多细胞生物，多孔动物门（Porifera），又称海绵动物门（Spongia）生物。没有任何组织系统，就像多个单细胞生物的聚集体，被切割后的每一块海绵还能再生成新的独立个体。不能移动，靠细胞分泌的酸性物质溶解礁石、珊瑚（往往导致整片珊瑚礁死亡）而固着其上，从淡水、潮间带到深海分布十分广泛，但多数为海生，靠流水滤食微生物而生。潜水时看到珊瑚上有孔洞一般都是被海绵干掉了。海绵的体内有不同种类的海藻共生，因此它们才呈现不同的色彩。人类和所有动物的祖先是至少在地球上生活了5亿年的海绵，而海绵的祖先是真菌。
因为吸水性佳，在水彩的创作中常常也用到天然海绵辅助毛笔，因为有独特的纹理同时又可以直接作为绘画工具。

Study human monocyte subsets
MNCs/ MKs [https://www.dreamstime.com/]
Monocytes (MNCs) play an important role in immune defense, inflammation, and homeostasis by sensing their local environment, clearing pathogens and dead cells, and initiating adaptive immunity, as well as providing a progenitor pool that contributes to inflammatory DCs and replenishes some tissue macrophages. MNCs are a heterogeneous and plastic cell population. It’s subset function has been more extensively studied in mouse models than in humans.
Subsets:
classical_ CD14++CD16–
non-classical_ CD14dimCD16+
intermediate_ CD14++CD16+
Differentiation induction:
mo-DCs_ IL-4, GM-CSF [mainly by CD14++CD16– subset]
M1 macrophage_ GM-CSF [all subsets]
M2 macrophage_ M-CSF [all subsets]
Functional observations of human monocyte subsets documented in the literature are somewhat controversial, with different responses observed depending on the context of their activation.
