EZH2藉由PIP5K1C誘導鈣離子訊息傳遞調控人類間質幹細胞的神經分化 [PDF]
[[abstract]]EZH2是PcG蛋白群的一員,其功能在調節幹細胞的自我更新與分化。在PI(4,5)P2的合成過程PIP5K1C扮演著重要的角色。磷脂?C(phospholipase C)會將PI(4,5)P2水解成細胞內傳訊者IP3和DAG,其中IP3是細胞內鈣離子的活化者。在神經分化過程中,細胞內鈣離子濃度改變是必須且關鍵的。然而,EZH2是否調控細胞內鈣離子訊息傳遞,以及它是如何調控人類間質幹細胞(hMSCs)的神經分化,其機制目前尚未清楚。在本研究中,偵測神經標記的表現結果顯示 ...

雉鸡(Phasianus colchicus)是国内主要经济鸟类之一,也是分布最广、亚种分化最多、地理变异最复杂的种类之一。《中国动物志鸟纲第四卷鸡形目》一书对其分类、亚种分化、地理变异等方面作了迄今最完整的叙述。本文仅就甘肃雉鸡亚种分化、分布、地理变异等作进一步探讨。一、亚种分化甘肃雉鸡有甘肃亚种(P.c.strauchi)、南山亚种(P.c.satscheuensis)、阿拉善亚种(P.c.sohokhotensis)和华东亚种(P.c.torquatus)共4个亚种 ...

Abstract This paper examines the concept of non‐understandable in psychotherapy, based on the author's own play therapy with a boy with mild ASD (autism spectrum disorder). ASD is considered to belong to an area beyond comprehension, as psychotherapy is often deemed ineffective for it.

Looking at Us Through Their Eyes. The Analytical Process from Ethnographic Perspectives1
Abstract This article looks at the analytical situation through the Others’ eyes—through examples from contemporary ethnographies of foreign cultures. It discusses the following issues: a) The analogy between the ontological worlds of the dead, ghosts, animals and dreams in “primitive populations” and the analytical psychological descriptions of the ...

本文主要以莴苣髓部外植体为材料研究了激素,多胺,一些糖和氨基酸及丁酸钠,二甲亚砜对导管分子分化的影响,结果表明,生长素、细胞分裂素和糖是外植体中导管分子分化调控中的关键因素。生长素和细胞分裂素可能是导管分子分化诱导因子。糖可能有两方面的作用:提供壁合成原料和提供分化所需能量。多胺可以部分取代细胞分裂素的作用。游离羟脯氨酸抑制了外植体细胞分裂和导管分子分化。与壁代谢有关的木糖,苯丙氨酸对导管分子分化有促进作用,说明细胞壁合成的调节机制是分化调节机制中的—部分 ...

The collective application of shorebird tracking data to conservation
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Comprehensive framework for assessing and optimizing existing research networks
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...
