Tissue Microarray Analysis Applied to Bone Diagenesis

Tissue Microarray Analysis Applied to Bone Diagenesis

Taphonomic processes affecting bone post mortem are important in forensic, archaeological and palaeontological investigations. In this study, the application of tissue microarray (TMA) analysis to a sample of femoral bone specimens from 20 exhumed individuals of known period of burial and age at death is described. TMA allows multiplexing of subsamples, permitting standardized comparative analy...

Correspondence analysis applied to microarray data.

Correspondence analysis is an explorative computational method for the study of associations between variables. Much like principal component analysis, it displays a low-dimensional projection of the data, e.g., into a plane. It does this, though, for two variables simultaneously, thus revealing associations between them. Here, we demonstrate the applicability of correspondence analysis to and ...

Gene set analysis methods applied to chicken microarray expression data

BACKGROUND Gene set analysis is considered to be a way of improving our biological interpretation of the observed expression patterns. This paper describes different methods applied to analyse expression data from a chicken DNA microarray dataset. RESULTS Applying different gene set analyses to the chicken expression data led to different ranking of the Gene Ontology terms tested. A method fo...

Stability-based cluster analysis applied to microarray data

This paper studies the estimation of the number of clusters using the so-called stability-based approach, where clusters obtained for two subsets of the data set are compared via a similarity index and the decision regarding the number of clusters is taken based on the statistics of the index over randomly selected subsets. We introduce a new similarity index , and analyze the consistency of th...
