概括

法医昆虫学家现在可以准确地将吹幼虫的年龄确定为最小死后间隔 (minPMI) 估计. 一种新的组织学方法改善了组织制备,在没有先进技术的情况下,产生了更清晰的切片,可供可靠的老化.

科学领域:

法医昆虫学法医昆虫学
发展生物学发展生物学

背景情况:

吹对于估计自死亡以来的时间至关重要 (最小死后间隔,minPMI).
衰老的未成熟的吹,特别是在幼中,是准确minPMI的关键.
对于幼儿阶段的传统组织学是具有挑战性的,因为组织透和碎片化很差.

研究的目的:

介绍一种有效的方法,用于制备吹飞内婴儿阶段的组织学段.
为了改善的透,并获得干净的,整个部分用于形态分析.
使用可访问的组织学技术,提高minPMI估计的准确性.

主要方法:

开发了一种新的组织学准备技术,用于吹幼虫.
优化了对的透,以克服由丰富的脂肪体引起的问题.
利用改进的部分来识别可靠的特定年龄的形态标记.

主要成果:

在幼儿组织中实现了最大限度的透.
生产了干净和完整的组织学截面,保留了形态细节.
证明了这些部分对于识别特定年龄标记的有用性.

结论:

提出的方法有效地准备了吹飞膜组织学切口.
该技术通过可靠的老化,提高了minPMI估计的准确性.
当先进的,昂贵的方法对法医研究人员来说不可行时,它提供了一个有价值的替代方案.

Fixation and Sectioning

Fixation and Sectioning

Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
