متن کاملPrinciples of laser microdissection and catapulting of histologic specimens and live cells.
Rapid contact- and contamination-free procurement of specific samples of histologic material for proteomic and genomic analysis as well as separation and transport of living cells can be achieved by laser microdissection (LMD) of the sample of interest followed by a laser-induced forward transport process [laser pressure "catapulting," (LPC)] of the dissected material. We investigated the dynam...
متن کاملA microfluidic-enabled mechanical microcompressor for the immobilization of live single- and multi-cellular specimens.
A microcompressor is a precision mechanical device that flattens and immobilizes living cells and small organisms for optical microscopy, allowing enhanced visualization of sub-cellular structures and organelles. We have developed an easily fabricated device, which can be equipped with microfluidics, permitting the addition of media or chemicals during observation. This device can be used on bo...
متن کاملType specimens, samples of live individuals and the Galapagos Pink Land Iguana
The nomenclatural implications of Gentile & Snell (2009)'s innovations in the designation of a type specimen that is sampled and tagged but not killed are discussed. The paper also responds to Nemésio (2009)'s criticism of Donegan (2008), where I argued that descriptions based on samples of live individuals are valid. I also discuss whether recent descriptions of such a nature involve a differe...
متن کاملAedes albopictus in Africa? First records of live specimens in imported tires in Cape Town.
Live larvae of Aedes albopictus have been found entering South Africa in used tire casings imported from Japan on 3 separate occasions. This is the first evidence that this mosquito is entering Africa and underlines the value of mosquito monitoring programs to detect the importations of this important vector. It is suggested that undetected populations of Ae. albopictus may have already become ...
