The highly heterogeneous nature of biological specimens present in small animals results in a wide distribution of optical properties and high inherent autofluorescence that demands tomographic approaches with spectral priors, in the form of emission spectra of the fluorophores (literature method), for improved reconstructions [ 27, 28].
Local farmers found three specimens in a small quarry in the Liaoning province of north-east China.
She probably relied for models on specimens in the Small Mammal House of a zoo, and consulted reference works in the library of the Natural History Museum to aid her work.
An immunohistochemistry (IHC) assay was used to detect PD-L1 protein expression in the cytoplasm and on the cell surface of tumor specimens in 2 small NSCLC cohorts, one with 52 frozen sections 10 and the other with 109 formalin-fixed paraffin-embedded (FFPE) sections.
Apparently, quicklime-stabilized specimens proved to be mechanically stronger which indicate a potential to sustain higher bearing loads than hydrated lime-stabilized specimen albeit in small measures at the various dosage levels.
In particular, the Munich, Eichstätt, Solnhofen, and Thermopolis specimens differ from the London, Berlin, and Haarlem specimens in being smaller or much larger, having different finger proportions, having more slender snouts lined with forward-pointing teeth, and possible presence of a sternum.
In general, staining will provide better results if it is performed in larger resected specimens rather than in smaller specimens from biopsies.
Upon arrival in the laboratory, surgical tonsil specimens were cut in small pieces using sterile instruments.
To accomplish this, specimens were placed in small polypropylene tubes: either 0.2 ml PCR tubes, or heat-sealed pipette tips.
