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。

 

 

 

ImageJ to add arrows to targeted cells

Using ImageJ/”Straight” tool to add arrows to cell pictures as below:

  1. right click to switch the default “Straight Line” to “Arrow tool”
  2. double click to set arrow size/outlook
  3. open a picture, mark a line on the target site press “D”, burn in arrow
  4.  or open ROI Manager to mark multiple arrows to one picture

 

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++CD16subset]

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.
